DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown:

[0022] Embodiment 1: The utility model provides a safety inspection and prying device for underground production and mining sites of a mine, comprising: an inspection and prying mechanism 1, comprising an inspection and prying bar assembly 11, a first positioning assembly 12 and a second positioning assembly 13 arranged on the outer side of the inspection and prying bar assembly 11, and a guide block 14 is fixedly connected to the first positioning assembly 12; a steel drill mechanism 2, comprising a slider assembly 21 which is limitedly slidably embedded on the inspection and prying bar assembly 11, and a steel drill assembly 22 which is fixedly connected to one side of the slider assembly 21, the first positioning assembly 12 and the second positioning assembly 13 can both position the slider assembly 21, the steel drill assembly 22 is slidably embedded on the guide block 14, and the first positioning assembly 12 and the second positioning assembly 13 have the same structure;

[0023] Among them, the staff can perform normal prying operations through the pry bar assembly 11, move the slider assembly 21 and abut it on the first positioning assembly 12, and the guide block 14 can play a guiding role. At this time, the first positioning assembly 12 can position the slider assembly 21, and the steel drill assembly 22 is inserted into the rock wall or ore pile. The pumice and loose ore can be detected by poking. At the same time, by poking the rock with the steel drill, the stability of the rock can be preliminarily judged. If the rock is obviously loose or broken under the poking, it may mean that there are safety hazards in the area. The steel drill assembly 22 can play a lighting role. After use, the positioning of the first positioning assembly 12 is released, and the slider assembly 21 is moved so that it can be positioned against the second positioning assembly 13, thereby facilitating the staff to store the steel drill assembly 22.

[0024] Specifically, the inspection crowbar assembly 11 includes an inspection crowbar trunk 111 , one end of the inspection crowbar trunk 111 is fixedly connected to an oblique prying steel head 112 , and the other end of the inspection crowbar trunk 111 is fixedly connected to a curved prying steel head 113 .

[0025] Specifically, the first positioning assembly 12 includes a positioning block 121 , a positioning clamping block 122 and a spring 123 . A guide rod 124 is fixedly connected to the interior of the positioning block 121 , and a pressing rod 125 is fixedly connected to one side of the positioning clamping block 122 .

[0026] Specifically, the positioning block 122 and the spring 123 are both limitedly slidably embedded on the guide rod 124, and the spring 123 drives the positioning block 122 to move away from the inspection crowbar trunk 111.

[0027] As can be seen from the above, pushing the pressing rod 125 can make the positioning block 122 slide along the guide rod 124 and compress the spring 123. At this time, the positioning block 122 moves and disengages from the slider assembly 21, thereby facilitating the staff to move the position of the slider assembly 21. After releasing the pressing rod 125, the spring 123 resets and moves the positioning block 122, thereby facilitating the next positioning use.

[0028] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the slider assembly 21 includes a slider body 211, on which a positioning groove 212 is provided; the steel drill assembly 22 includes a steel drill body 221, on which a lighting lamp 222 is fixedly connected, and on the outer side of the steel drill body 221 a button 223 is fixedly connected. The design of the lighting lamp 222 facilitates workers to work in places with dim light.

[0029] Specifically, the slider body 211 is slidably embedded in the inspection crowbar trunk 111, the slider body 211 and the steel chisel body 221 are fixedly connected, the positioning block 122 can be inserted into the positioning groove 212, and the button 223 can control the switch of the lighting lamp 222.

[0030] As can be seen from the above, moving the slider body 211 can fix the positioning groove 212 by the positioning block 122, and the lighting lamp 222 can be turned on by controlling the button 223. The staff can illuminate the local area through the lighting lamp 222 to facilitate observation. At the same time, the tip of the steel drill body 221 can be poked on the rock to judge the stability of the rock.
