Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of mine smelting technology, and particularly relates to a rotation-preventing device for a double-miner car dumper. BACKGROUND

[0002] The double-miner car dumper is a main unloading device for a miner car, and its common driving mode is that a motor drives a speed reducer, the speed reducer drives a rotating drum to drive the dumper to rotate, and the unloading of the miner car is completed; since daily maintenance work needs to be carried out in the rotating body of the dumper, the rotation of the dumper is caused by the unbalance of the rotating body and the misoperation of others due to external reasons. SUMMARY

[0003] The utility model discloses a rotation-preventing device for a double-miner car dumper, which solves the problem that the existing double-miner car dumper lacks a rotation-preventing device during maintenance.

[0004] The utility model discloses the following technical scheme: a rotation-preventing device for a double-miner car dumper, which comprises a threaded connecting rod, outer threads are arranged at both ends of the threaded connecting rod, U-shaped joints are threadedly connected to both ends of the threaded connecting rod respectively, inner threads are arranged on the straight sections of the U-shaped joints, and a pin shaft is arranged between the vertical sections of the U-shaped joints.

[0005] The utility model has the advantages that the outer threads arranged at both ends of the threaded connecting rod and the inner threads arranged on the U-shaped joints are matched with each other, the connection strength can be increased, the connection process is simple, fastening is reliable, the threaded connecting rod can be easily disassembled, the length of the connecting rod can be effectively increased, the U-shaped joints can balance the load, disperse stress, improve the stability of the connection, and increase the firmness of the connection between the threaded connecting rod, the rotating body of the double-miner car dumper and the ground base steel plate. BRIEF DESCRIPTION OF DRAWINGS

[0006] Figure 1 It is a use state schematic diagram of the utility model;

[0007] Figure 2 It is a three-dimensional structure schematic diagram of the utility model;

[0008] Figure 3 It is Figure 2 It is an enlarged view of position A in the middle.

[0009] In the drawing: 1 is a rotation-preventing device; 1a is a pin shaft; 1b is a U-shaped joint; 1c is a threaded connecting rod; 1d is a support plate; 2 is a rotating body of a double-miner car dumper; and 3 is a ground base steel plate. DETAILED DESCRIPTION

[0010] The technical scheme of the utility model is described below in connection with the drawings and implementation methods.

[0011] As shown in the drawings, Figure 1 The anti-rotation device 1 is used to connect and fix the double-miner car dumper rotating body 2 and the ground base steel plate 3, so as to prevent the rotation of the double-miner car dumper.

[0012] As shown in the drawings, Figures 2-3 The anti-rotation device for the double-miner car dumper comprises a threaded connecting rod 1c, the threaded connecting rod 1c is provided with external threads at both ends, the threaded connecting rod 1c is respectively threadedly connected with U-shaped joints 1b at both ends, the U-shaped joints 1b are provided with internal threads at straight sections, and a pin shaft 1a is inserted between vertical sections of the U-shaped joints 1b, and one of the U-shaped joints 1b is connected with a support plate 1d through the pin shaft 1a between the vertical sections.

[0013] The threaded connecting rod 1c is connected with the two U-shaped joints 1b at both ends through internal and external thread cooperation, so as to adjust the length of the anti-rotation device 1, one end of the threaded connecting rod 1c is welded with the ground base steel plate 3 through the support plate 1d, and the other end of the threaded connecting rod 1c is fixed with the double-miner car dumper rotating body 2 through the U-shaped joint 1b and the pin shaft 1a. Specifically, the threaded connecting rod 1c is provided with external threads at both ends, and the U-shaped joints 1b are provided with internal threads, which are arranged to make the length of the anti-rotation device 1 adjustable, more applicable, and further make the connection and fixation of the anti-rotation device 1 with the double-miner car dumper rotating body 2 and the ground base steel plate 3 reliable.

[0014] During the maintenance operation of the double-miner car dumper, the positions of the U-shaped joints 1b at both ends of the threaded connecting rod 1c are adjusted through threads, so that the length of the anti-rotation device 1 is appropriate, the U-shaped joints 1b are fixed with the double-miner car dumper rotating body 2 through the pin shaft 1a, and the support plate 1d is welded with the ground base steel plate 3, so as to form a triangular stable structure, and further prevent the rotation of the double-miner car dumper rotating body 2. After the operation is completed, the pin shaft 1a is removed, the fixation of the anti-rotation device 1 with the double-miner car dumper rotating body 2 is released, and the anti-rotation device 1 is placed aside without affecting the normal operation of the double-miner car dumper.
