Description

Technical Field

[0001] This utility model relates to the technical field of open-pit coal mining equipment, and in particular to a slope reinforcement device for open-pit coal mining areas. Background Technology

[0002] Slope reinforcement devices in open-pit coal mines are safety protection systems used to enhance slope stability and prevent landslides and collapses. Their core structure typically includes components such as anchor bolts (cables), lattice beams, retaining walls, and anti-slide piles, combined with surface protection measures such as geogrids and shotcrete. The strength of the soil and rock mass is enhanced through mechanical anchoring, prestressing tensioning, or grouting reinforcement. Some devices also integrate real-time monitoring sensors to dynamically provide feedback on slope displacement, stress, and other data. This device features a modular design and adaptability to complex geological conditions, effectively reducing the risk of slope instability during mining and ensuring operational safety and production efficiency.

[0003] In the prior art, Chinese utility model patent CN220847647U, authorized by the Ministry of Industry and Information Technology, relates to the field of coal mine slope protection technology and discloses a slope stabilization mechanism for open-pit coal mining areas. The mechanism includes a slope body, with rivets inserted and fixed within the slope body. A reinforcing mechanism is provided on the circumferential surface of the rivets, comprising a threaded rod fixedly connected to the circumferential surface of the rivets, a transverse reinforcing rod connected to the circumferential surface of the threaded rod, and a nut threadedly connected to the circumferential surface of the threaded rod for positioning the transverse reinforcing rod. A protective mechanism is provided on the circumferential surface of the rivets. This utility model achieves the effect of reinforcing coal mine slopes with simple operation, stabilizing them and reducing the likelihood of landslides.

[0004] The aforementioned slope stabilization mechanism for open-pit coal mining areas cannot adjust the reinforcement position of the slope according to the terrain during use, making it difficult for the slope reinforcement device to meet the needs of different terrains, and its application range needs to be improved.

[0005] Therefore, there is an urgent need for a slope reinforcement device for open-pit coal mining areas. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a slope reinforcement device for open-pit coal mining areas.

[0007] The present invention solves its technical problem through the following technical solution: a slope reinforcement device for open-pit coal mining areas, comprising a crossbeam, a longitudinal beam installed above the crossbeam, and a reinforcement mechanism disposed on one side of the crossbeam for reinforcing the slope of the open-pit coal mining area. It also includes a connecting mechanism disposed above the longitudinal beam for installing slope protection equipment in the open-pit coal mining area. The reinforcement mechanism includes a notch, which is uniformly cut at the middle of the crossbeam and the longitudinal beam. A groove is provided at the middle of the notch, and a T-shaped slide rail is provided on the inner wall of the groove. A bolt rod is slidably connected to the inner wall of the T-shaped slide rail, and a pressure block is slidably connected to the outer side of the bolt rod. A fastening nut is threadedly connected to one end of the bolt rod.

[0008] As a further embodiment of this utility model: the connecting mechanism includes a square hole, which is uniformly cut in the middle of the longitudinal beam. A helical spring is fixedly installed at the bottom of the square hole, and a slider is fixedly installed at one end of the helical spring. A connecting bolt is threadedly connected to the middle of the slider.

[0009] As a further improvement of this utility model: multiple support legs are evenly arranged below the crossbeam, and a lead screw is connected to the middle position of each support leg.

[0010] As a further embodiment of this utility model: a hexagonal screw is fixedly installed at one end of the lead screw, and a rotating base is rotatably connected to one end of the hexagonal screw.

[0011] As a further improvement of this utility model, multiple bolt brackets are evenly arranged on the outer side of the rotating base.

[0012] As a further improvement of this utility model: a reinforcing protective net is slidably connected to the outside of the connecting bolt, and multiple positioning holes are evenly arranged in the middle of the reinforcing protective net.

[0013] As a further improvement of this utility model, the pressure block is slidably connected to the longitudinal beam.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. By setting the bolt rod and sliding connection, the crossbeam and longitudinal beam can move relative to each other along the notch. By tightening the nut and threaded connection of the bolt rod, the pressure block is pressed. The friction generated by the pressure block is used to position the crossbeam and longitudinal beam. During use, the position of the crossbeam and longitudinal beam can be adjusted according to the terrain, thereby adjusting the reinforcement position of the slope in the mining area.

[0016] 2. The screw is driven to rotate by a hexagonal screw. The screw rotates along the inner wall of the support leg, which can drive the screw to rise and fall. This allows the slope reinforcement device in the open-pit coal mining area to connect and fix uneven coal mining slopes, thus expanding the application range of the slope reinforcement device in the open-pit coal mining area.

[0017] 3. By sliding the slider to the square hole, the slider moves up and down along the square hole. Under the elastic connection of the spiral spring, the reinforced protective net can be elastically connected to the coal mine slope. This allows the slope reinforcement device in the open-pit coal mining area to elastically block falling coal blocks, reduce the impact of the coal mine on the reinforced protective net, and extend the service life of the reinforced protective net.

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example 1: As Figure 3-7As shown, a slope reinforcement device for an open-pit coal mining area includes a crossbeam 100, a longitudinal beam 200 installed above the crossbeam 100, and a reinforcement mechanism disposed on one side of the crossbeam 100. This device is used to reinforce the slope of the open-pit coal mining area. The reinforcement mechanism includes a notch 101, which is uniformly cut at the midpoint of the crossbeam 100 and the longitudinal beam 200. A groove 102 is cut at the midpoint of the notch 101. A T-shaped slide rail 103 is cut on the inner wall of the groove 102. A bolt rod 104 is slidably connected to the inner wall of the T-shaped slide rail 103. The bolt rod 104 is slidably connected to the groove 102, allowing the crossbeam 100 and the longitudinal beam 200 to move relative to each other along the notch 101. A pressure block 105 is slidably connected to the outer side of the bolt rod 104. 05 is slidably connected to the longitudinal beam 200. One end of the bolt rod 104 is threaded with a fastening nut 106. The fastening nut 106 is threaded with the bolt rod 104 to press the pressure block 105. Multiple support legs 107 are evenly welded below the crossbeam 100. A lead screw 108 is connected to the middle position of the support leg 107. The lead screw 108 can be raised and lowered by rotating along the inner wall of the support leg 107. A hexagonal screw 110 is fixed to one end of the lead screw 108 by a bolt. The hexagonal screw 110 drives the lead screw 108 to rotate. A rotating base 120 is rotatably connected to one end of the hexagonal screw 110. Multiple bolt brackets 130 are evenly welded to the outside of the rotating base 120. The rotating base 120 rotatably connects the bolt brackets 130 and the hexagonal screw 110.

[0033] In this embodiment, by setting the bolt rod 104 to slide and the slide groove 102, the crossbeam 100 and the longitudinal beam 200 can move relative to each other along the notch 101. By fastening the nut 106 and threadedly connecting the bolt rod 104, the pressure block 105 is pressed. The friction generated by the pressure block 105 is used to position the crossbeam 100 and the longitudinal beam 200. During use, the position of the crossbeam 100 and the longitudinal beam 200 can be adjusted according to the terrain conditions, thereby adjusting the reinforcement position of the coal mining area slope. The hexagonal screw 110 drives the lead screw 108 to rotate. The rotation of the lead screw 108 along the inner wall of the support leg 107 can drive the lead screw 108 to rise and fall. This allows the open-pit coal mining area slope reinforcement device to connect and fix uneven coal mining slopes, expanding the application range of the open-pit coal mining area slope reinforcement device.

[0034] During the process of installing the bolt rod 104 into the slide groove 102, the bolt rod 104 is first inserted into the slide groove 102, with at least a portion of the upper end of the bolt rod 104 extending out of the slide groove 102. Then, the pressure block 105 is placed on the upper end of the bolt rod 104. Finally, the fastening nut 106 is installed by threading it to the bolt rod 104.

[0035] Example 2: Figure 1-7 As shown, an open-pit coal mine slope reinforcement device further includes a connecting mechanism installed above a longitudinal beam 200 for installing slope protection equipment in the open-pit coal mine. The connecting mechanism includes a square hole 201, which is uniformly cut in the middle of the longitudinal beam 200. A helical spring 202 is fixed to the bottom of the square hole 201 by bolts. A slider 203 is fixed to one end of the helical spring 202 by bolts. The slider 203 is slidably connected to the square hole 201 and moves up and down along the square hole 201. A connecting bolt 204 is threadedly connected to the middle of the slider 203. A reinforcement protective net 400 is slidably connected to the outside of the connecting bolt 204. Multiple positioning holes 210 are uniformly cut in the middle of the reinforcement protective net 400. Multiple connecting bolts 204 are fixedly connected to the reinforcement protective net 400 through the positioning holes 210. One end of the bolted frame 130 is fixedly connected to the slope of the open-pit coal mine.

[0036] In this embodiment, the slider 203 is slidably connected to the square hole 201, so that the slider 203 moves up and down along the square hole 201. Under the elastic connection of the helical spring 202, the reinforced protective net 400 can be elastically connected to the slope of the open-pit coal mining area, so that the slope reinforcement device of the open-pit coal mining area can elastically block the falling coal blocks, reduce the impact of the coal mine on the reinforced protective net 400, and extend the service life of the reinforced protective net 400.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
