Description

Technical Field

[0001] This invention relates to the field of hoisting technology, and in particular to a hoisting device for preventing the falling of scrap steel plates in steel rolling machinery. Background Technology

[0002] A crane is a type of lifting and moving machinery widely used in ports, workshops, power plants, construction sites, and other places. The term "crane" is a general term for lifting machinery. The most common types of cranes are truck cranes, crawler cranes, and tire cranes. Cranes are used for lifting equipment, disaster relief, hoisting, and rescue operations.

[0003] The patent application "CN215974521U" describes "a single steel plate hoisting device, including an overhead crane and an electromagnetic hoisting mechanism that works in conjunction with the overhead crane; multiple chains are provided at the lower end of the electromagnetic hoisting mechanism; electromagnets are suspended at the lower end of the chains; limit switches and thickness gauges are provided on the sides of the electromagnets; and a weighing instrument is also provided on the chains. The thickness gauge on the electromagnet is used to determine the thickness of the steel plate and the relationship between the magnetic force and the load, enabling rapid hoisting of the steel plate; the limit switch contacts are located at the lower end of the electromagnet, effectively determining whether the electromagnet has reached the required position before energizing; the weighing instrument measures changes in gravity to determine whether the steel plate should be hoisted, ensuring hoisting safety. This device effectively solves the problems of low efficiency and wasted labor in hoisting single steel plates, achieving the advantages of intelligent hoisting of single plates and saving operation time." The aforementioned patent can effectively solve the problems of low efficiency and wasted manpower in lifting single steel plates, and realize the advantages of intelligent lifting of single plates by the device, saving operation time. However, the existing technology uses electromagnetic attraction to transport steel plates, but it can only operate on a single steel plate. When the lifting equipment collides during transportation, it will cause the steel plate to fall off. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a scrap steel plate lifting device for steel rolling machinery, which solves the problem that existing technologies use electromagnetic attraction to transport steel plates, but can only operate on a single steel plate. When the lifting equipment collides during transportation, the steel plate will fall off.

[0005] To achieve the above objectives, the present invention employs the following technical solution: A scrap steel plate lifting device for steel rolling machinery to prevent it from falling off includes: hoisting beams; Two support frames are fixedly connected to the upper end of the hoisting beam; The anti-fall-off mechanism has two sets, one of which includes: A hydraulic cylinder is fixedly connected to the upper end of the support frame; The push ring is fixedly connected to the surface of the thin rod of the hydraulic cylinder; The push plate is fixedly connected to the thin rod of the hydraulic cylinder; The connecting rod is slidably connected to the upper end of the hoisting beam; A connecting block is rotatably connected to one end of the connecting rod; The slider is fixedly connected to the lower end of the connecting block; The mounting strip is fixedly connected to the side end of the hoisting beam; The hook is rotatably connected to the lower end of the mounting strip; A sliding groove is fixedly connected to the upper end of the hook block, and the slider is slidably connected within the sliding groove.

[0006] Furthermore, wear-resistant pads are fixedly connected to the sides of the six hook blocks and the two push plates, and the eight wear-resistant pads are made of rubber material.

[0007] Furthermore, the upper end of the hoisting beam is fixedly connected to two fixing strips, and the upper end of the hoisting beam and the upper end of the two fixing strips are both fixedly connected to a fixing seat.

[0008] Furthermore, two protective tubes are fixedly connected to the upper ends of both support frames, and each of the two protective tubes has a through hole at its upper end.

[0009] Furthermore, four reflective pads are fixedly connected to both ends of the hoisting beam, and two protective pads are fixedly connected to both ends of the hoisting beam.

[0010] Furthermore, the upper end of the hoisting beam is fixedly connected to four limit rails, and the two connecting rods are slidably connected within the four limit rails respectively.

[0011] Furthermore, the lower end of the hoisting beam is provided with three square slots, and multiple ribs are fixedly connected in each of the three square slots.

[0012] Furthermore, the lower end of the push ring is provided with a rubber layer, and the upper end of the hoisting beam has two through holes.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by connecting the lifting equipment to the fixed base, moving the lifting beam to the top of the scrap steel pile, and then operating the hydraulic cylinder to drive the connecting rod downward, the hydraulic cylinder pushes the hook block to hook the scrap steel, while the push plate pushes the scrap steel, so that the hook block fixes the scrap steel to the bottom of the lifting beam. This allows multiple scrap steels to be transported, while also increasing the fixing effect between the scrap steel and the lifting beam, effectively preventing the scrap steel from falling during transportation.

[0014] 2. In this invention, the reflective pad installed on the surface of the hoisting beam enables workers to locate the hoisting beam in low ambient light conditions; the wear-resistant pad installed on the surface of the hook block increases the stability of the hook block and the steel plate; and the protective pad installed on the surface of the hoisting beam protects the surface of the hoisting beam.

By cooperating with the hook block 13, it can be used to drive the hook block 13 to swing. The slider 20 is fixedly connected to the lower end of the connecting block 6. By sliding in the groove 19, the hook block 13 can swing freely. Mounting strip 16 is fixedly connected to the side end of hoisting beam 1 and can be used to install connecting block 6; Hook block 13 is rotatably connected to the lower end of mounting strip 16.

[0018] like Figure 3 As shown, wear-resistant pads 7 are fixedly connected to the sides of the six hook blocks 13 and the two push plates 14, which can increase the friction between the hook blocks 13 and the steel plate. The eight wear-resistant pads 7 are made of rubber material, which can effectively protect the hook blocks 13.

[0019] like Figure 2 As shown, two fixing strips 9 are fixedly connected to the upper end of the hoisting beam 1, which can increase the connection strength between the fixing seat 2 and the hoisting beam 1.
