DETAILED DESCRIPTION

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0024] like Figure 1-Figure 6 The present embodiment shows that the brake shoe wear detection device for a mining hoist provided by the present embodiment comprises a mounting plate 4, a second clamping plate 3 is mounted on one end of the mounting plate 4, a first clamping plate 1 is arranged on one side of the second clamping plate 3, the first clamping plate 1 is connected to the second clamping plate 3 through a plurality of first screws 2, the first screws 2 are threadedly connected to the second clamping plate 3, the first clamping plate 1 is driven to move by rotating the first screw 2 and approach the second clamping plate 3, the first clamping plate 1 is gradually moved by rotating the first screw 2, and can be clamped near the brake shoe of the hoist through the gap between the first clamping plate 1 and the second clamping plate 3, and the clamping is convenient;

[0025] Two mounting frames are installed on the side of the mounting plate 4, and the mounting frames are respectively located at both ends of the mounting plate 4, and a displacement sensor 10 is installed on the mounting frame at one end close to the second clamping plate 3, and the displacement sensor 10 model is MN18-08DLU, and an active kit is installed on the mounting frame at the other end; a display 18 is connected to one end of the displacement sensor 10 through a wire, and an alarm horn is provided on the display 18. When the degree of wear is large, that is, when the displacement distance difference of the measuring plate 11 is large, an alarm is issued.

[0026] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the mounting frame includes a collar 5, a carrier plate 14 is installed on one side of the collar 5, and the carrier plate 14 is connected to the mounting plate 4 by bolts, which is convenient for installation and disassembly. The top and bottom of the collar 5 are both threadedly connected with a second screw rod 6, one end of the second screw rod 6 is installed with a handle 15, and the other end of the second screw rod 6 is installed with a cushion block 16. During installation, the object placed in the collar 5 can be fixed by rotating the second screw rod 6, and because the second screw rod 6 is threadedly connected, it is more convenient to replace;

[0027] The movable kit includes a slide cylinder 7, a slide rod 8 is slidably installed inside the slide cylinder 7, a connecting plate 9 is installed at one end of the slide rod 8, and a measuring plate 11 is installed at the other end of the slide rod 8. An inner sleeve 13 is installed inside the end of the slide cylinder 7 close to the connecting plate 9. The measuring plate 11 is connected to the inner sleeve 13 inside the slide cylinder 7 through a spring 12. The spring 12 can stretch the slide rod 8 to reset the measuring plate 11. The connecting plate 9 is connected to the brake shoe or brake shoe disc through a wire rope, etc., and the movement of the brake shoe or brake shoe disc drives the slide rod 8 to move. The moving distance of the measuring plate 11 is monitored by the displacement sensor 10. If the brake shoe is worn, its moving distance will change. The degree of wear of the brake shoe is obtained according to the displacement change difference monitored by the displacement sensor 10, so that it is convenient to replace it after the horn alarm on the display 18 is sounded later; the connecting plate 9 can also be directly connected to the brake shoe disc, and the movement of the measuring plate 11 is directly driven by the brake shoe disc; but it will be more flexible and convenient when connected by ropes such as wire ropes, and the installation of the mounting plate 4 is also more flexible and convenient.
