[0009] S3: Tighten the wire rope: operate the hand chain hoist to tighten the wire rope;

[0010] S4: Transferring the old chain box: Under the action of manpower, the chain box is pushed to move along the tightened wire rope from the maintenance position to the spare parts storage position, and then the old chain box is removed;

[0011] S5: Fix the new chain box: Fix the new chain box to the wire rope with two shackles;

[0012] S6: Transferring the new chain box: Use the hand chain hoist to tighten the wire rope, and under human power, the new chain box is quickly moved along the wire rope from the spare parts storage position to the maintenance position;

[0013] S7: Install the new chain box: Install the new chain box at the maintenance position.

[0014] S8: Repeat the above steps until all the chain boxes of the apron feeder are replaced.

[0015] As a further solution of the present invention: The length of the steel wire rope is adjusted according to the actual distance between the on-site maintenance position and the spare parts storage position in the working environment.

[0016] As a further solution of the present invention: The load of the chain block is 1 ton.

[0017] As a further solution of the present invention: The fixed connection mode between the chain block and the steel wire rope is that the hook of the chain block directly hooks the end of the steel wire rope, and an anti-detachment device is provided at the connection between the hook of the chain block and the steel wire rope to prevent the steel wire rope from falling off the hook during the stress process.

[0018] The advantages of the present invention compared with the prior art are as follows: This method shortens the time for overhauling and replacing the chain boxes of the apron feeder by half, greatly reduces the labor intensity, and well solves the problems of low efficiency, high labor intensity and high safety risk in overhauling and replacing the chain boxes of the apron feeder.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a technical solution: To solve the existing problems proposed in the background art.

[0025] Combined with the attached Figure 1It can be known that the chain box body 1 includes a bottom plate 1.1, support plates 1.2 are fixed at both ends of the bottom plate 1.1, and a shackle 2 is fixed on the side of the support plate 1.2 near the top. A wire rope 3 is passed through the shackle 2, and one end of the wire rope 3 is fixed at the on-site maintenance position, and the other end is fixedly connected to the hand chain hoist. The hand chain hoist is located at the spare parts storage position, and the length of the wire rope 3 can be adjusted according to the actual distance between the on-site maintenance position and the spare parts storage position in the working environment. The load of the hand chain hoist is set to 1 ton. The fixed connection method of the hand chain hoist and the wire rope 3 is that the hook of the hand chain hoist directly hooks the end of the wire rope 3, and an anti-drop device is provided at the connection between the hook of the hand chain hoist and the wire rope 3 to prevent the wire rope 3 from falling off the hook during the force application process. Replacement steps The method is as follows: first, the old chain box on the plate feeder is removed, and then the two shackles 2 are used to fix the removed old chain box on the installed wire rope 3 and keep the wire rope 3 in a loose state to facilitate the fixing operation of the chain box, and then the hand chain hoist is operated to tighten the wire rope 3, and then the chain box is pushed by manpower to move it from the maintenance position to the spare parts storage position along the tightened wire rope 3 and then the old chain box is removed, and then the new chain box is fixed to the wire rope 3 with two shackles 2, and then the wire rope 3 is tightened by the hand chain hoist and the new chain box is quickly moved from the spare parts storage position to the maintenance position along the wire rope 3 under manpower, and then the new chain box is installed at the maintenance position, and finally the above steps are repeated until the replacement of all chain boxes of the plate feeder is completed.

[0026] The working principle of this application is: this method uses a simple transfer system constructed by a wire rope 3 and a hand chain hoist to realize the rapid transfer of the chain box between the maintenance position and the spare parts storage position. The core is to use the coordinated operation of mechanical tensioning and human push to complete the disassembly and transfer of the old chain box and the installation and return of the new chain box. The specific process is as follows:

[0027] Device construction: Fix the shackle 2 on the top of the support plate 1.2 of the chain box body 1 and pass the wire rope 3. The two ends of the wire rope 3 are respectively anchored at the on-site maintenance position and the hand chain hoist connected to the spare parts storage position to form a cross-regional transfer channel.

[0028] Treatment of the old chain box: first remove the old chain box, fix it on the loose wire rope 3 through the shackle 2, tighten the wire rope 3 with the hand winch, and then manually push the chain box along the wire rope 3 from the maintenance position to the spare parts storage position.

[0029] Reinstall the new chain box: fix the new chain box to the wire rope 3 in the same way, tighten the wire rope 3 again, and then push the new chain box along the wire rope 3 to the inspection position with human assistance to complete the installation.

[0030] Circular operation: Repeat the above operation until all chain boxes are replaced.

[0031] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
