Description

Technical Field

[0001] The utility model relates to a steel wire rope fixing fixture used for overhauling a hoisting mechanism of a crane. Background Art

[0002] The maintenance work of the wire rope winding system of the crane hoisting mechanism is generally the replacement and installation of parts. The main work on site includes the replacement of the fixed pulley group, the replacement of the ground wheel group, and the replacement of the wire rope. The conventional replacement of the above important parts is generally carried out after the wire rope is removed, and then the fixed pulley group and the ground wheel group (hook group or fixed gantry hook sling) are replaced and installed. After the installation is completed, the wire rope is re-threaded and installed. The re-threading of the wire rope on site requires the cooperation of multiple people, which has high risks, long operation time and high labor intensity.

[0003] The hoisting mechanism of a crane generally adopts a multi-ratio pulley form to reduce the load-bearing capacity of each wire rope and increase the overall lifting capacity of the hoisting mechanism. The larger the ratio of the hoisting mechanism pulley group, the more wire ropes pass through the pulley system, so the more difficult it is to install on site. Sometimes, there are situations on site where the wire rope does not need to be removed and replaced synchronously because the wire rope has not reached its service life, but the fixed pulley group and the movable pulley group (hook group or fixed gantry hook sling) need to be replaced. To replace the fixed pulley group and the hook group, it is generally necessary to replace the wire rope when the hook group is on the ground and is in a relaxed state. Since the pulley group is a rotating component, multiple wire ropes repeatedly move up and down on the pulley due to different forces, which increases the difficulty of on-site maintenance operations. Summary of the invention

[0004] The utility model aims to provide a wire rope fixing fixture for the overhaul of a crane hoisting mechanism, which prevents the wire rope from moving up and down, thereby achieving the purpose of safely, efficiently and quickly replacing large parts of a hoisting mechanism pulley system.

[0005] The technical solution adopted by the utility model is a wire rope fixing fixture for the overhaul of a crane hoisting mechanism, comprising a rope clamp and a rope clamp connecting plate, the rope clamp connecting plate being a long strip plate, a plurality of rope clamps being fixed by bolts and evenly spaced on the rope clamp connecting plate, a wire rope channel being formed between the rope clamp and the rope clamp connecting plate, the rope clamp and the rope clamp connecting plate being matched and connected to each other to vertically and side by side fix the crane hoisting mechanism wire ropes passing through each wire rope channel in sequence; an auxiliary wire rope is also arranged on the rope clamp connecting plate, and the working position of the rope clamp connecting plate is pulled and adjusted by the auxiliary wire rope.

[0006] The utility model fixes the wire rope in a relaxed state to prevent the wire rope from moving up and down, thereby realizing the rapid replacement of the fixed pulley block and the movable pulley block (hook block or fixed gantry hook sling), and at the same time can simplify the replacement operation steps, realize the improvement of maintenance efficiency and the reduction of the labor intensity of on-site workers. The utility model is to solve the problem of fixing the relative position of all the wire ropes on one side during the replacement operation of the fixed pulley block or the movable pulley block (hook block or fixed gantry hook sling) without removing the wire rope, prevent the wire rope from moving up and down, thereby realizing the purpose of safely, efficiently and quickly replacing large parts of the lifting mechanism pulley system. The manufactured wire rope fixing fixture fixes the wire ropes on both sides respectively, and is manufactured by combining and assembling the rope clamp connecting plate and the standard wire rope rope clamp. The rope clamp connecting plate is processed into a long round strip, which is convenient for adjusting the cranes of different specifications due to the different lateral distances of the wire rope, and is convenient for rapid installation and removal on site. This design is suitable for the rapid replacement of fixed pulley blocks or movable pulley blocks (hook blocks or fixed gantry hook slings) of large-tonnage hoisting mechanisms that adopt multi-ratio designs. It achieves the goal of not dismantling or scrapping the wire rope, simplifies the operation sequence, and thus reduces the workload and labor intensity of maintenance personnel.

[0007] This design has been tested on site, and the results have shown that the special fixture for fixing wire ropes can effectively fix the wire ropes of the lifting mechanism in a relaxed state, avoiding the up and down movement of the wire ropes. The application of the special fixture for fixing wire ropes solves the current situation where the adjustment of the wire ropes is difficult due to the relative position change of the wire ropes. This method allows the replacement of large parts without dismantling or damaging the wire ropes, and shortens the maintenance operation time by more than 40%, thereby improving the maintenance operation efficiency and reducing the labor intensity of on-site operators. Therefore, the special fixture for fixing wire ropes can be widely used as a tool for fixing wire ropes in crane maintenance operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is a schematic diagram of the main structure of the utility model;

[0009] Figure 2 It is a side structural schematic diagram of the utility model. Implementation

[0010] A wire rope fixing fixture for overhauling a crane hoisting mechanism, such as Figure 1 , 2As shown, it includes a rope clamp 2 and a rope clamp connecting plate 4. The rope clamp connecting plate 4 is a long strip plate. A number of rope clamps 2 are fixed on the rope clamp connecting plate 4 by bolts and are evenly spaced. A wire rope channel is formed between the rope clamp 2 and the rope clamp connecting plate 4. The coordinated connection between the rope clamp and the rope clamp connecting plate fixes the crane hoisting mechanism wire ropes 1 passing through each wire rope channel vertically and side by side in sequence; an auxiliary wire rope 3 is also arranged on the rope clamp connecting plate 4, and the working position of the rope clamp connecting plate 4 is pulled and adjusted by the auxiliary wire rope 3.

[0011] When replacing the hook group of the fixed pulley block, it is generally necessary to replace the hook group (or gantry hook sling) when the wire rope is in a relaxed state. Since the pulley block is a rotating component, multiple wire ropes repeatedly move up and down on the pulley due to different forces. The wire ropes become more and more tangled on site, which affects the efficiency of on-site maintenance operations. Through on-site observation and analysis, the structure of the utility model can effectively fix the relative positions of all wire ropes in the pulley system in a relaxed state, that is, it can achieve the purpose of quickly replacing large components (fixed pulley block, movable pulley block) in the lifting mechanism pulley system without removing the wire rope.
