Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The following is combined Figures 1-5 This invention describes a safety protection device for mining engineering.

[0030] In one embodiment, a safety protection device for mining engineering includes: a protective device 100, which consists of a protective plate 101 and a fixed bracket 102;

[0031] The side protection mechanism 200 includes a side plate 201 and a drive assembly. The side plate 201 is disposed on both sides of the protective plate 101, and the drive assembly is disposed on the top of the protective plate 101 for adjusting the angle of the two side plates 201.

[0032] The drive assembly includes a gear 205 and a toothed plate 204. The gear 205 is respectively disposed on the top of the side plate 201. The gear 205 is meshed with the toothed plate 204. The toothed plate 204 is fixedly installed on the side wall of the movable plate 203. The top of the protective plate 101 is provided with a drive module for pushing the movable plate 203 to move back and forth.

[0033] An auxiliary component 207 is provided between the two sets of side plates 201 on the back side wall of the protective plate 101, and a buffer mechanism 300 is provided on the outer side of the protective plate 101.

[0034] like Figure 2 and Figure 3As shown, the drive module includes an electric telescopic rod 202, a top frame 103 is provided on the top of the protective plate 101, a partition is provided in the middle of the inner wall of the top frame 103, the bottom end of the electric telescopic rod 202 is provided on the side walls of the partition, and the working ends of the electric telescopic rod 202 are fixedly connected to the side walls of the movable plate 203 respectively.

[0035] The inner wall of the top frame 103 is provided with a groove 206, and the protrusions on the side wall of the toothed plate 204 are slidably disposed inside the groove 206.

[0036] In this embodiment, when the angle of the side plate 201 needs to be adjusted, the worker controls the working end of the electric telescopic rod 202 to extend through the external controller. The extension of the working end of the electric telescopic rod 202 pushes the movable plates 203 on both sides to move outward, thereby causing the toothed plates 204 on the side wall of the movable plates 203 to drive the gears 205 to rotate. This causes the gears 205 to drive the side plates 201 on both sides of the protective plate 101 to rotate, thereby adjusting the angle of the side plate 201. The specific rotation angle is adjusted according to the distance the movable plates 203 are pushed out.

[0037] When the side plates 201 on both sides are moved to adjust their angle, auxiliary components 207 are provided on the back sidewalls of the two sets of side plates 201. These auxiliary components 207 assist in adjusting the angle of the two sets of side plates 201, increasing the stability of the side plates 201 during rotation. For example... Figure 3 As shown, the auxiliary component 207 includes an I-beam 214, support plates 208, and vertical rods 209. The I-beam 214 is disposed on the back side wall of the protective plate 101. Two sets of support plates 208 are disposed on the side wall of the side plate 201, respectively. The vertical rods 209 are fixedly disposed between the two sets of support plates 208. An auxiliary module is disposed between the outside of the vertical rods 209 and the I-beam 214.

[0038] The auxiliary module includes an inner telescopic rod 210 and an outer cylinder 211. The end of the inner telescopic rod 210 is rotatably disposed outside the vertical rod 209, and the bottom end of the outer cylinder 211 is rotatably disposed inside both sides of the I-beam 214. A groove 213 is provided inside the outer cylinder 211, and the other end of the inner telescopic rod 210 is slidably disposed inside the groove 213.

[0039] An auxiliary spring 212 is provided inside the groove 213, and the end of the auxiliary spring 212 is fixedly connected to the end of the inner telescopic rod 210 located inside the groove 213.

[0040] In this embodiment, when the two sets of side plates 201 are driven to adjust their angle, the end of the inner telescopic rod 210 rotates along the outer surface of the vertical rod 209, and the other end of the inner telescopic rod 210 slides inside the outer cylinder 211. At the same time, the end of the outer cylinder 211 is rotatably set inside the I-beam 214, and an auxiliary spring 212 is provided inside the outer cylinder 211 on the side wall of the inner telescopic rod 210. The auxiliary spring 212 buffers the force when the inner telescopic rod 210 slides inside the outer cylinder 211, so as to increase the stability when the side plate 201 is driven to rotate.

[0041] like Figure 4 and Figure 5 As shown, the buffer mechanism 300 includes a buffer plate 301 and a pressure plate 303. The buffer plate 301 has a notch 302 on the side wall facing the protective plate 101. The end of the pressure plate 303 is rotatably disposed on the inner walls of both sides of the notch 302, and the other end of the pressure plate 303 is slidably disposed inside the buffer groove 307 opened on the side wall of the protective plate 101.

[0042] The other end of the pressure plate 303 is rotatably sleeved on the outside of the limiting post 304. The inner top surface and inner bottom surface of the buffer groove 307 are provided with guide grooves 308. The two ends of the limiting post 304 are slidably disposed inside the guide groove 308. The inside of the guide groove 308 is provided with a buffer spring 306. The side frame 305 is provided between the limiting posts 304 at the upper and lower ends of the pressure plate 303 and faces the side wall of the buffer spring 306. The ends of the buffer spring 306 are fixedly connected to the side wall of the side frame 305 respectively.

[0043] In this embodiment, before use, the buffer spring 306 pushes out the buffer plate 301 so that it does not contact the side wall of the protective plate 101. During use, the buffer plate 301 is pressed against the protective plate 101 under the impact force of external explosion. The pressure plate 303 is pressed by the buffer plate 301. The side frame 305 on the side wall of the limiting post 304 at the end of the pressure plate 303 presses the buffer spring 306, causing the side frame 305 to slide towards both ends of the buffer groove 307, so as to buffer the external impact force.

[0044] Working principle: After the worker fixes the fixed bracket 102 in the installation position, the working end of the electric telescopic rod 202 is extended through the external controller. The movable plate 203 is driven to move outward by the electric telescopic rod 202. During the movement of the movable plate 203, the toothed plate 204 drives the gear 205 to rotate, thereby causing the gear 205 to drive the side plate 201 to rotate, thus realizing the angle adjustment of the side plate 201 without manual adjustment. Moreover, the rotation angle of the side plate 201 can be adjusted according to the distance that the movable plate 203 is pushed out.

[0045] It should be noted that the electric telescopic pole 202 and external controller mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the electric telescopic pole 202 and external controller can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
