Description

Technical Field

[0001] This utility model belongs to the field of crane equipment technology, specifically relating to a maintenance platform for a crane beam. Background Technology

[0002] Bridge cranes are lifting equipment that spans across workshops, warehouses, and material yards for material handling. Because their ends rest on tall concrete pillars or metal supports, they resemble bridges. The bridge frame of a bridge crane runs longitudinally along rails laid on elevated structures on both sides, making full use of the space beneath the bridge frame for material handling without being obstructed by ground equipment. It is the most widely used and numerous type of lifting machinery.

[0003] Some bridge cranes have electric hoists installed at the bottom of both crossbeams for lifting. However, sometimes when one of the electric hoists is damaged or needs repair in the laboratory, workers usually have to move it from the top of both crossbeams to repair it. However, the height of the electric hoist is lower than the crossbeam, which makes subsequent repairs inconvenient and poses a certain danger to personnel. Summary of the Invention

[0004] The present invention mainly addresses the technical problems existing in the prior art by providing a maintenance platform for a crane beam.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a maintenance platform for a crane beam, comprising two opposing beams, characterized in that: a bottom slide rail is provided at the bottom of each beam, a drive mechanism for forward and backward movement is slidably provided on the surface of the bottom slide rail, an electric hoist is installed at the bottom of the drive mechanism, a hook is connected to the bottom of the electric hoist, a top slide groove is provided at the top of each beam, a maintenance platform is slidably provided between the two top slide grooves, the maintenance platform is disposed in the space between the two beams, and the maintenance platform is located between the two electric hoists.

[0006] Preferably, pulley frames are provided on both sides of the crossbeam, and a first motor is provided on the top side of the pulley frame and coaxially connected to the pulley of the pulley frame.

[0007] Preferably, the maintenance platform includes two opposing side plates, with baffles slidably connected to the front and rear sides between the two side plates, and a base plate connected to the bottom of both the two side plates and the two baffles. The base plate, baffles, and side plates together form the maintenance platform. The base plate is fixedly connected to the baffles on both sides, and slots for lifting and storing the corresponding side plates are provided on both sides of the base plate.

[0008] Preferably, the maintenance platform is provided with a slide on both the left and right sides. The top of the slide is bent towards the crossbeams on both sides, and multiple rollers are rotatably provided on the top of the slide corresponding to the top slide groove.

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] Example: A maintenance platform for a crane beam, such as Figures 1-2As shown, the device includes two opposing crossbeams 1. Each crossbeam 1 has a bottom slide rail 15 at its bottom. A drive mechanism 16 for forward and backward movement is slidably mounted on the surface of the bottom slide rail 15. An electric hoist 18 is mounted on the bottom of the drive mechanism 16. A hook 19 is connected to the bottom of the electric hoist 18. Each crossbeam 1 has a top slide groove 14 at its top. A maintenance platform 2 is slidably mounted between the two top slide grooves 14. The maintenance platform 2 is located in the space between the two crossbeams 1 and between the two electric hoists 18. A fixed hook and a strap connect the maintenance platform 2 and the electric hoist 18 to enable the maintenance platform 2 to move forward and backward.

[0016] Both sides of the crossbeam 1 are provided with pulley frames 12. A first motor 13 is provided on the top side of the pulley frame 12 and is coaxially connected to the pulley of the pulley frame 12. The crossbeam 1 can move back and forth by the first motor 13 on both sides driving the pulley frame 12 to roll.

[0017] The maintenance platform 2 includes two opposing side plates 21. Baffles 24 are slidably connected to the front and rear sides of the two side plates 21. A base plate 25 is connected to the bottom of both the side plates 21 and the two baffles 24. The base plate 25, baffles 24, and side plates 21 together form the maintenance platform 2. The base plate 25 is fixedly connected to the baffles 24 on both sides. The base plate 25 has corresponding slots 251 on both sides for lifting and storing the side plates 21. Slides 22 are provided on both the left and right sides of the maintenance platform 2. The tops of the slides 22 are bent towards the crossbeams 1 on both sides, and the tops of the slides 22 are rotatably mounted corresponding to the top slide groove 14. Multiple rollers 23 and a slide 22 are slidably mounted on the crossbeam 1 via the rollers 23. Multiple slide rods 27 are provided on the left and right sides of the top of the base plate 25. An anti-detachment plate 26 is provided on the top of the multiple slide rods 27 on one side to fix the multiple slide rods 27 together. Limiting plates 28 are provided at the bottom of the side plates 21 on both sides. The slide rods 27 are slidably inserted into the limiting plates 28.

[0018] The principle of this utility model is as follows: When the drive mechanism 16 or electric hoist 18 at the bottom of one side of the crossbeam 1 breaks down, the worker climbs up the scaffold to the maintenance platform 2 between the two crossbeams 1. Before use, the maintenance platform 2 is set on one side of the two crossbeams 1 to facilitate the worker's entry. Then, the worker uses a fixed hook and a strap to tie one end to the working electric hoist 18 and the other end to the maintenance platform 2. The worker then turns on the drive mechanism 16 of the working side to move the maintenance platform 2 to the broken side. The worker turns on the multiple second motors 210 on the maintenance platform 2. The multiple second motors 210 are turned on synchronously through control, which drives the gear 211 at the output end to roll. As a result, the gear 211 drives the rack 29 to move downward, which causes the baffle 24 and the bottom plate 25 fixed to the rack 29 to move downward, making it easier for the worker to repair the broken electric hoist 18. After the repair is completed, the worker returns via the drive mechanism 16.
