The invention aims at the high height of the existing crane and the high cost of the factory building, and provides a kind of crane in the main engine room of the power plant. The crane has a low height and low cost of the factory building.

Adjustable wheel axle sleeve

technical field

The patent relates to a wheel equipment, in particular to an adjustable wheel axle sleeve.

Background technology

The traditional LD wheel axle sleeve is concentric, because there are errors in the machining of the shaft of the LD wheel set, and it can not be changed. Therefore, there is a certain horizontal and vertical deviation in the installation of the wheel group, which affects the running of the driving and even gnawing on the rail.

summary of the invention

The invention provides a adjustable wheel axle sleeve, which can avoid deviation when installing the wheel shaft sleeve of the wheel shaft sleeve of the existing technology, and can ensure the installation precision of the wheel group.

An adjustable span test bed

technical field

The patent relates to a crane experimental equipment, in particular to an adjustable span test rig.

Background technology


     

A crane needs to do the internal action experiments before the crane is out of the factory. In this way, a test bed is needed. At present, some construction has a fixed collapse, but the span of the crane is different, and the construction of a fixed span test bench can not meet the needs.

summary of the invention

In view of the existing technology, the invention can not meet the experimental requirements of different span cranes, and provides an adjustable span test bed, which is very convenient to adjust the span of the portal frame according to the span of the crane.

A centralized discharge device for condensate water in a crane's air conditioning

technical field

The invention relates to a crane auxiliary equipment, in particular to a centralized drainage device for condensing water of a crane air conditioner.

Background technology

With the continuous improvement of living standards, the probability of using the air conditioner is increasing gradually. However, some unit work environment is not allowed to sprinkled water droplets, so that these units can not use the crane with air conditioning, making the indoor environment not suitable for work and sound normal work.

summary of the invention

The invention provides a centralized discharge device for the condensing water of the crane air conditioning in view of the limited use range of the crane with air conditioning with the existing technology, and the water discharged by air conditioning on the crane will not sprinkled on the ground, greatly enlarging the use range of the crane with air conditioning.

A double beam car with a hanging hook

technical field

The patent relates to a crane equipment, and specifically relates to a double hanging beam trolley with a downward suspension hook.

Background technology

The traditional hoisting double beam car is to install the lifting mechanism on the platform surface of the small frame. The height of the small frame of this structure is relatively large, so the height of the workshop must be relatively large so as to make the lifting mechanism work normally, but it can not be used in some small car frames with small upper space.

summary of the invention

The invention aims at the problem of the high height of the existing double beam trolley and occupying space, and provides a double beam car with a hanging hook, which is highly reduced and suitable for a workshop with a small space in the upper part of the small frame and has a wide range of application.


A hoist gourd trolley

technical field

The patent relates to a crane equipment, in particular to a suspension type gourd trolley.

Background technology

The traditional gourd trolley is mounted on a small frame table with a seat type electric hoist. This structure has a large height above the rail surface and can not be used in a small workshop with small frame upper space.

summary of the invention

The invention aims at the problem that the height of the existing gourd trolley is relatively large and does not apply to the workshop with small upper space in the small frame, and provides a hoist hoist car with a low overall height and wide application range.

A wheel axle

technical field

The patent relates to a vehicle accessory, in particular to a vehicle axle.

Background technology

The diameter of the traditional LD270 axle shaft is 75mm. The diameter of the axle head of phi 75mm needs a series of turning with the rod of 80mm, which wastes a lot of material and has a long processing time.

summary of the invention

The invention aims at the problem of wasting a lot of material and low processing efficiency when machining the existing wheel shaft, and provides a car wheel shaft, which saves raw material and has high processing efficiency.

A railing

technical field

The patent relates to a walking auxiliary equipment, in particular to a railing.

Background technology

30x30x3 angle steel is used to directly weld the angle steel column of 50x50x5. When the product span is large, the bar cross bar needs to be made to the installation site and then reassemble, weld and fill the field, and the stiffness and strength of the 30x30x3 angle steel are low, and the safety hidden danger exists for a long time.

summary of the invention

The invention provides a railing with the advantages of convenient installation and firm connection, aiming at the existing problems of troublesome and unsafe installation.

A main beam

technical field

The patent relates to a crane supporting device, in particular to a main beam.

Background technology

The traditional main beam is welded by an upper cover plate, a lower cover plate and two web plates, but the inner space of the main beam is very small. The builders can't enter the internal welding of the beam. The four longitudinal angle welds of the main beam are welded by submerged arc automatic single side welding. When the current is too large, it is easy to cause welding defects on the back of the weld, causing stress concentration and reducing the strength of the weld, while the current is too small, it can easily lead to defects such as penetration and inclusion, and the strength of the weld is reduced, and the welding parameters are difficult to master.

summary of the invention

Aiming at the problem that the existing main beam is not easy to weld, the invention provides a main beam, which is easy to weld and has strong connection.

A light frame

technical field

The patent relates to lighting equipment, and specifically relates to a lamp holder.

Background technology

The fixed lamp holder and the beam body are fixed only by one bearing, which is fastened by a bolt group. Because of the high height of the lamp holder itself, only a fixed point on the upper end of the lamp holder can not restrain the swing of the lower end of the lamp holder. Therefore, during the running process, the lamp holder will easily collide with the main beam, resulting in the breakage of the lamp and even the lamp. Falling, there is a security risk.

summary of the invention

Aiming at the problem of unsafe installation and use of the existing lamp holder, the invention provides a lighting rack, which is firmly installed and safe to use.

A kind of platform railings

technical field

The patent relates to a walking auxiliary equipment, in particular to a walking rail.

Background technology

The traditional platform column 2 adopts 50x50x5 angle steel, the upper slope is 120 degree angle, the 50x50x5 angle steel is small in lateral bearing capacity, and the man can help and slosh more. There is a hidden danger of safety. The width of the width 50mm can not be used to hit the railing tube with a diameter of 30mm hole.

summary of the invention

Aiming at the unsafe problem of the prior art, the invention provides a walking railing, which is safe to use and can also play a 30mm hole.

A treadmill

technical field

The patent relates to a crane bridge tread, in particular to a treadle pedal.
