Description

Technical Field

[0001] The utility model relates to the technical field of iron and steel metallurgical crushing equipment, in particular to a mobile auxiliary roll removing mechanism for a double-roll crusher. Background Art

[0002] The double-roll crusher is a device commonly used in the iron and steel metallurgical industry to crush minerals such as coke and anthracite. Through the mutual meshing of the relatively rotating rollers and the crushing teeth on their surfaces, the crushing effect of the material is achieved, which is high and will not be affected by the shape of the material. Since the minerals have a certain hardness and various crushed stones mixed in the minerals will accelerate the wear of the crushing teeth on the rollers, the rollers need to be maintained or replaced after the double-roll crusher has been used for a period of time.

[0003] At present, truss lifting equipment is generally installed in the factory area to lift the materials and equipment in the factory area. This kind of truss lifting equipment is a common lifting tool in the factory area. Therefore, when the roller of the double-roll crusher needs to be maintained or replaced, the truss lifting equipment in the factory area is usually used to lift the roller so that the roller is separated from the main body of the double-roll crusher.

[0004] Truss hoisting equipment uses flexible chains to hoist rollers. Since flexible chains are often very long, during the hoisting process, a small impact (such as changes in the moving speed of the truss hoisting equipment) will cause the roller to swing significantly. In addition, the roller is heavy, so such swinging will threaten the safety of personnel in the factory (especially those who are close to the roller). Therefore, the above problems need to be solved urgently. Summary of the invention

[0029] The utility model further provides a lifting assembly at the middle position of the lower surface of each movable sleeve seat 9, and the lifting end of each lifting assembly is arranged downward, and performs lifting action in the vertical up and down direction; wherein each lifting assembly is arranged at intervals between the corresponding front and rear adjacent rollers 12, and each lifting assembly includes a winch 14, a cable limiting sleeve 23, a cable 22, a limiting sleeve 15, a guide rod 16, a pulley 17, a pulley seat 18 and a fixing ring 24; such as Figures 1 to 3As shown, a limiting sleeve 15 is vertically provided in the middle position of the lower surface of each movable sleeve 9, and a guide rod 16 is coaxially sleeved in each limiting sleeve 15, and the lower end of each guide rod 16 vertically extends downward from the lower surface of the corresponding limiting sleeve 15, and is respectively vertically slidably connected with the corresponding limiting sleeve 15; a pulley seat 18 is fixedly provided at the lower end of each guide rod 16, and a pulley 17 is vertically and longitudinally sleeved at the lower end of each pulley seat 18, and each pulley 17 is connected to the corresponding pulley seat 18.

[0032] The working principle of this utility model:

[0033] First, move the base 1 to the outside of the roller crusher, and make the pulley 17 correspond to the end of the roller. Then, after the limiting components on the end of the roller are disassembled, use chains or steel cables to tie the two ends of the roller, and then put one end of the chain or steel cable into the corresponding rope groove 20 to shorten the distance between the roller and the rope seat 19, greatly reduce the shaking amplitude of the roller, and protect the personal safety of workers near the roller.

[0034] Then, driven by the winch 14, the cable 22 is wound up so that the V-shaped angle between the two ends of the cable 22 becomes larger and larger, so that the pulley 17 is lifted upward and the roller is lifted upward synchronously;

[0035] During the lifting process of the pulley 17, the limiting sleeve 15 limits the guide rod 16, thereby constraining the freedom of the pulley 17 so that it can only perform lifting and lowering linear motion in the vertical direction, thereby improving the stability of the roller hoisting, avoiding the danger of large-scale shaking, and improving the safety of the roller hoisting operation;

[0036] After the roller is hoisted to a certain height, the base 1 is driven to move by the driving wheel 5, and the roller can be transferred to the specified position. During this process, the taut cable 22 and the limit sleeve 15, the guide rod 16, and the pulley 17 are mutually constrained, so that the pulley 17 and the cable 22 can be relatively fixed, thereby further improving the stability of the roller during the hoisting and moving process.

[0037] Beneficial effects of the utility model:

[0038] (1) The utility model uses a chain or a steel cable to tie the two ends of the roller, and then puts the end of the chain or the steel cable into the rope groove 20 on the rope seat 19, so that the pulley 17 and the rope seat 19 can be driven by the hoist 14 to make the vertical up and down movement, thereby realizing the disassembly and assembly of the auxiliary roller, minimizing the problem of the roller shaking during the lifting process, and improving the stability and safety of the roller lifting process;

[0039] (2) The utility model can not only be moved to a designated position in a workshop for roller hoisting, but also can be moved and hoisted in an open field, assisting the roller in or out during disassembly or installation, thereby reducing the limitations of the field on its hoisting and expanding its scope of application.
