Description

Technical Field

[0001] The invention relates to the technical field of protective scaffolding, in particular to a movable protective scaffolding in a mining area. Background Art

[0002] During the mining process, the rock structure of the mountain will become unstable due to mining activities. For example, blasting operations will cause cracks in the mountain rocks. Under the subsequent natural weathering and rain erosion factors, the rocks are prone to loosening and falling off. Protective scaffolding can effectively block these falling rocks and protect the safety of personnel and equipment in the mining area. Some mines are located in seismic activity zones or areas with complex geological structures. Crustal movement can cause mountain rock collapse. Protective scaffolding is like a barrier that can reduce the impact of falling rocks on the working area below.

[0003] In the existing mining process, the mining face is constantly advancing and changing. With the excavation of coal, the mining work will be transferred from one area to an adjacent area. In order to facilitate the migration of the protective shed, the protective shed needs to be designed to be movable so that the protective shed can be moved to the new work area in time to continuously provide effective protection for the mining equipment and workers. In order to achieve the mobile function, the movable protective shed is mostly designed to be easy to disassemble and assemble, and the structure is also relatively light, which makes the overall structural stability of the movable protective shed less than that of the fixed protective shed. When facing the large impact force that occurs during the mining process, the movable protective shed has a weak resistance ability, and thus cannot guarantee the safety of the mining personnel.

[0004] Therefore, we propose a movable protective shed for mining areas to solve the above-mentioned problems. Summary of the invention

[0010] Preferably, the other ends of the plurality of springs are respectively fixedly connected to the outer surfaces of the plurality of limit plates, and one ends of the plurality of telescopic tubes are respectively movably extended through the outside of the plurality of mounting columns.

[0011] Preferably, the movable component includes a pressure-resistant plate, and slideways are fixedly installed on the top of the pressure-resistant plate near the two side edges, and sliding rods are slidably sleeved on the outer surfaces of the two slideways, and the tops of the two sliding rods are fixedly connected to the bottoms of the two pressure-resistant plates respectively.

[0012] Preferably, a limiting frame is fixedly connected between the outer surfaces of the two sliding rods, and extension rods are fixedly mounted on the opposite inner walls of the two limiting frames by screws.

[0015] Preferably, two ends of the threaded rod are movably inserted into opposite outer parts of the pressure-resistant plate, and the outer surface of the threaded rod is connected to the inner thread of the limiting frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In order to ensure the firmness and stability of the protective shed, two protective frames made of metal steel are used as the main support of the protective shed, and then the firmness of the protective shed is further enhanced by the arc-shaped arc top, and the stability of the protective shed is further enhanced by the setting of multiple triangular support rods.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-8 The present invention provides a technical solution: a movable protective scaffolding in a mining area, comprising a moving component 1 for facilitating the transfer of the protective scaffolding, a reinforcing component 2 is arranged on the top of the moving component 1, the reinforcing component 2 comprises two protective frames 201 for supporting the protective scaffolding, a plurality of arc-shaped tops 202 for dispersing the load of the protective scaffolding are fixedly welded between the tops of the two protective frames 201, a plurality of arc-shaped tops 202 for dispersing the load of the protective scaffolding are fixedly welded between the opposite inner walls of the plurality of arc-shaped tops 202 for bearing the load of the protective scaffolding, a web 204 for transmitting the vertical force of the protective scaffolding is fixedly welded near the center of the tops of the plurality of webs 203, a triangular support rod 205 for enhancing the compressive strength of the protective scaffolding is fixedly welded on the opposite outer surfaces of the plurality of webs 204, a mounting sleeve 206 is fixedly welded between the tops of the plurality of arc-shaped tops 202, the tops of the mounting sleeves 206 are fixedly welded to a plurality of mounting columns 207, a spring 208 is arranged on the inner bottom surfaces of the plurality of mounting columns 207, and the interiors of the plurality of mounting columns 207 are slidably connected with a limiting plate 209.

[0023] In this embodiment, in order to ensure the safety of workers in the mining area, it is often necessary to install protective scaffolding in the mining area. In order to further ensure the firmness and stability of the protective scaffolding, two protective frames 201 made of metal steel are first used as the main support of the protective scaffolding, and then the firmness of the protective scaffolding is further enhanced by the arc-shaped arc top 202. When the arc top 202 bears the weight of falling ore and rain and snow, it will generate horizontal thrust, which can convert the vertical load into axial pressure and transfer it to the two protective frames 201 along the arc curve shape. This makes the load of the entire protective scaffolding more evenly dispersed, avoiding stress concentration in a certain place, thereby significantly improving the overall bearing capacity of the protective scaffolding and better coping with the mine. In order to cope with various heavy impact situations that may occur in the mining area, the stability of the protective scaffolding is further enhanced by the arrangement of multiple triangular support rods 205, wherein a triangular beam is formed between the triangular support rod 205 and the web rod 204 connected thereto. In the principle of mechanics, the triangle is one of the most stable structural forms. When the top of the protective scaffolding is subjected to various external forces, the triangular beam can keep its shape basically unchanged. When encountering strong winds, the triangular beam can effectively resist the horizontal thrust and upward suction generated by the wind, thereby preventing the protective scaffolding from being deformed by the wind. Multiple cross beams 203 can be used to bear the load of the protective scaffolding, thereby further improving the stability of the protective scaffolding, solving the problem that most existing mining protective scaffoldings in the prior art have simple structures and weak resistance capabilities.

[0024] like Figure 1-Figure 3 and Figure 6-Figure 8As shown, a movable protective scaffolding in a mining area includes a movable component 1 for facilitating the transfer of the protective scaffolding, a reinforcing component 2 is arranged on the top of the movable component 1, and the reinforcing component 2 includes two protective frames 201 for supporting the protective scaffolding, a plurality of arc-shaped tops 202 for dispersing the load of the protective scaffolding are fixedly welded between the tops of the two protective frames 201, cross beams 203 for bearing the load of the protective scaffolding are fixedly welded between the opposite inner walls of the plurality of arc-shaped tops 202, web bars 204 for transmitting the vertical force of the protective scaffolding are fixedly welded near the center of the tops of the plurality of cross beams 203, triangular support bars 205 for enhancing the compressive strength of the protective scaffolding are fixedly welded on the opposite outer surfaces of the plurality of web bars 204, mounting sleeves 206 are fixedly welded between the tops of the plurality of arc-shaped tops 202, and the tops of the mounting sleeves 206 are fixedly welded to a plurality of mounting columns 207, and the plurality of mounting columns 208 are fixedly welded to the tops of the plurality of arc-shaped tops 202. 07 is provided with springs 208 on the inner bottom surface, the interiors of the plurality of mounting columns 207 are slidably connected with limit plates 209, the outer surfaces of the plurality of limit plates 209 are fixedly installed with telescopic tubes 210, a buffer layer 211 for buffering the protective scaffolding is provided between one ends of the plurality of telescopic tubes 210, an outer sheath 212 is provided on the outer surface of the buffer layer 211, the bottom ends of the plurality of webs 204 are respectively fixedly connected with the inner top surfaces of the plurality of arc-shaped tops 202, the plurality of triangular support rods 205 are grouped into a group of two adjacent ones, one end of each group of triangular support rods 205 is respectively fixedly connected with the inner walls of the plurality of arc-shaped tops 202, one end of the plurality of springs 208 is respectively fixedly connected with the inner walls of the plurality of mounting columns 207, the other ends of the plurality of springs 208 are respectively fixedly connected with the outer surfaces of the plurality of limit plates 209, and one end of the plurality of telescopic tubes 210 is respectively movable through the outside of the plurality of mounting columns 207.

[0025] In this embodiment, in order to further improve the compressive strength of the protective scaffolding, when the crushed stones in the mine fall to the top of the protective scaffolding, the outer sheath 212 is first squeezed by the gravity of the crushed stones, driving the multiple telescopic tubes 210 to move toward the direction of the mounting column 207, thereby squeezing the multiple springs 208 and shortening them. Figure 8 As shown, the limit plate 209 limits the telescopic tube 210, and the multiple springs 208 extend under their own elastic force, thereby driving the multiple telescopic tubes 210 to move toward the buffer layer 211. Since the buffer layer 211 is made of a rubber material with a certain elasticity, the pressure resistance of the protective shed is further improved. By adding an elastic buffer device to the protective shed, the protective shed can buffer the impact force through its own elastic deformation at the moment when the falling object contacts the top of the protective shed, thereby reducing the damage to the protective shed structure caused by the falling object. In addition, the outer sheath 212 is made of aluminum alloy, and its purpose is to protect the buffer layer 211 to prevent it from being washed by rain and reducing its own elasticity. By adding a buffer device to the protective shed, the pressure resistance of the protective shed is further improved.

[0026] like Figure 1-Figure 5 As shown, the moving component 1 includes a pressure-resistant plate 101, and a slideway 102 is fixedly installed on the top of the pressure-resistant plate 101 near the edges on both sides. The outer surfaces of the two slideways 102 are slidably sleeved with slide rods 103, and the tops of the two slide rods 103 are respectively fixedly connected to the bottoms of the two pressure-resistant plates 101, and the outer surfaces of the two slide rods 103 are fixedly connected to the limiting frames 104, and the relative inner walls of the two limiting frames 104 are fixedly installed with extension rods 105 by screws. The opposite outer surfaces of the pressure-resistant plate 101 are provided with limiting grooves 106, and the outer surfaces of the two extension rods 105 are respectively slidably connected to the inner walls of the two limiting grooves 106, and a driving motor 107 is fixedly installed on the outer surface of one side of the pressure-resistant plate 101 by screws. The outer surfaces of the two driving motors 107 are fixedly connected with threaded rods 108, and the two ends of the threaded rods 108 are respectively movably penetrated to the opposite outer parts of the pressure-resistant plate 101, and the outer surfaces of the threaded rods 108 are connected to the internal threads of the limiting frames 104.

[0027] In this embodiment, in order to facilitate the movement of the protective scaffolding, when the protective scaffolding needs to be moved, the driving motor 107 is first started to drive the threaded rod 108 to rotate, thereby driving the limit frame 104 to move horizontally along the direction of the threaded rod 108. In order to ensure the stability of the movement of the limit frame 104, the two extension rods 105 are respectively inserted into the two limit grooves 106 to limit the limit frame 104. The movement of the limit frame 104 drives the two slide bars 103 to move along the directions of the two slideways 102 respectively, thereby driving the two pressure-resistant plates 101 to move along the two slideways 102, thereby driving the entire protective scaffolding to move forward until the protective scaffolding moves to the required position, and then the driving motor 107 can be turned off, and the staff can walk on the top of the pressure-resistant plate 101. Through the action of the moving component 1, the protective scaffolding can be moved without manual disassembly during the movement process, thereby reducing the labor intensity of the staff.

[0028] The use method and working principle of the device: In order to ensure the safety of the workers in the mining area, it is often necessary to install a protective shed in the mining area. When the protective shed needs to be moved, the driving motor 107 is first started to drive the threaded rod 108 to rotate, thereby driving the limit frame 104 to move horizontally along the direction of the threaded rod 108. The movement of the limit frame 104 drives the two slide bars 103 to move along the directions of the two slideways 102 respectively, and then drives the two pressure-resistant plates 101 to move along the two slideways 102, thereby driving the entire protective shed to move forward until the protective shed moves to the required position, and then the driving motor 107 can be turned off, and the workers can walk on the top of the pressure-resistant plates 101. In order to further ensure the firmness and stability of the protective shed, firstly, two protective frames 201 made of metal steel are used as the main support of the protective shed, and then the firmness of the protective shed is further enhanced by the arc-shaped arc top 202. Among them, the arc top 202 will generate horizontal thrust when it bears the weight of falling ore and rain and snow, which can convert the vertical load into The axial pressure is transformed into an axial pressure and transmitted to the two protective frames 201 along the arc curve shape, which makes the load of the entire protective shed more evenly dispersed, avoiding stress concentration in a certain place, thereby significantly improving the overall bearing capacity of the protective shed and better coping with various heavy object impacts that may occur in the mining area. The stability of the protective shed is further enhanced by the arrangement of multiple triangular support rods 205, wherein a triangular beam is formed between the triangular support rod 205 and the web rod 204 connected thereto. When the top of the protective shed is subjected to various external forces, the triangular beam can keep its shape basically unchanged. When encountering strong winds, the triangular beam can effectively resist the horizontal thrust and upward suction generated by the wind, thereby preventing the protective shed from being deformed by the wind. Multiple cross beams 203 can be used to carry the load of the protective shed. When the gravel in the mine falls to the top of the protective shed, it is first squeezed by the gravity of the gravel, and the outer sheath 212 is driven to move toward the direction of the mounting column 207, thereby causing the multiple springs 208 to be squeezed and shortened. Figure 8 As shown, the limiting plate 209 limits the telescopic tube 210, and the multiple springs 208 extend under their own elastic force, thereby driving the multiple telescopic tubes 210 to move toward the buffer layer 211. Since the buffer layer 211 is made of a rubber material with a certain elasticity, the pressure resistance of the protective shed is further improved. By adding an elastic buffer device to the protective shed, the protective shed can buffer the impact force through its own elastic deformation at the moment when the falling object contacts the top of the protective shed, thereby reducing the damage to the protective shed structure caused by the falling object.

[0029] The wiring diagram of the drive motor 107 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the drive motor 107 are no longer explained in detail.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
