Description

Technical Field

[0001] The present invention relates to the technical field of tunnel filling, and in particular to a filling body baffle device which can automatically unfold and actively fit into the tunnel wall. Background Art

[0002] Continuous mining and filling operation is a mining method that, as the mining face advances and isolation plates are arranged to block the filling body, waste rock, tailings, slag, construction waste and other materials are filled into the goaf or abscission zone to prevent deformation of the surrounding rock and improve production efficiency. The specific method is: after the coal mining tunnel is excavated, the on-site construction personnel will fill the tunnel with filling body, and arrange an isolation wall composed of multiple plastic boards (isolation boards) at the tunnel opening, supplemented by isolation cloth and other blockages to prevent the outflow of filling slurry.

[0003] The development of this process has mainly gone through the dry filling stage, water-sand filling stage, tailings cementation filling stage and high-concentration filling stage. Among them, tailings cementation filling technology is currently the most widely used filling technology. This technology, on the basis of fully processing solid waste resources such as coal gangue, realizes the effective control of surface subsidence and reduces the mine pressure manifestation of the working face.

[0004] However, under the action of ground stress, the shape of the sidewalls in coal mine tunnels is usually irregular, and the isolation plates are made of hard materials. As a result, the filling isolation plates used in the filling process cannot completely fit the left and right sides of the tunnel, which will cause leakage of the filling slurry, affect the filling rate, and may also cause serious roof subsidence, affecting the safe and efficient production of coal mines.

[0005] Currently, some mines address this issue by halting filling mid-process. Workers then lay a layer of isolation cloth near the left and right sides of the roadway. They then place hay and other debris outside the isolation cloth to fill the gap between the roadway side and the baffle, preventing leakage of the filling slurry. Pipelines for transporting the filling slurry are then placed above the roadway, and filling is resumed. However, this method is cumbersome to lay the filling material, as hay and isolation cloth cannot completely and effectively prevent slurry leakage. It is also time-consuming and labor-intensive, contradicting the mine's philosophy of efficient production. Summary of the Invention

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 making creative efforts are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a filling baffle device that can automatically unfold and actively fit the side of the tunnel to solve the problems existing in the prior art. It can fit the surface of the tunnel surrounding rock, has good isolation effect, and high construction efficiency.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-Figure 4As shown, this embodiment provides a filling body baffle device that can automatically unfold and actively fit the side of the tunnel, including a box body, a pressure detection element 1, a linkage element and a baffle body 15. The pressure detection element 1 is located outside the box body to facilitate the detection of the pressure in the tunnel. The linkage element and the baffle body 15 are both arranged in the box body. The side wall of the box body can squeeze the baffle body 15 and put the baffle body 15 in a folded state. After the tunnel begins to be filled and reaches a certain amount, the pressure detection element 1 can receive the pressure signal in the tunnel in real time, and after the pressure reaches the set value, the pressure signal is converted into an electrical signal and transmitted to the linkage element to control The linkage element is actuated, and when the linkage element is actuated, it can act on the side wall of the box body and open the side wall of the box body. At this time, the side wall of the box body no longer limits the baffle body 15, so that the baffle body 15 can be unfolded along the length direction of the tunnel side, realizing the automatic laying of the baffle body 15 and improving the construction efficiency. One side of the baffle body 15 is used to contact and fit the rock wall of the tunnel side, thereby preventing the filling slurry from leaking. At the same time, since the baffle body 15 is a foldable structure, the unfolding angle can be adaptively adjusted according to the shape of the rock wall, so that the baffle body 15 can better fit the surface of the tunnel surrounding rock, thereby improving the isolation and anti-seepage effect.

[0030] Specifically, the box body is equipped with a horizontally arranged isolation plate 7 and impact plate 10. The isolation plate 7 is located above the impact plate 10, and the distance between the isolation plate 7 and the top surface of the box body is preferably 35 mm. The linkage element is mounted on the isolation plate 7, and the impact plate 10 is provided with an impact hole 9. When the linkage element is activated, the active end of the linkage element can extend through the impact hole 9 and act on the side wall of the box body, causing the side wall of the box body to open, allowing the baffle body 15 to automatically deploy and conform to the rock wall of the roadway side. The box body is preferably a cubic shell made of hard plastic, with dimensions of 150 mm * 50 mm * 150 mm.

[0031] The linkage element includes a telescopic element 4, a slider 5, a spring 6 and an impact block 8. The fixed end of the telescopic element 4 is installed in the chamber above the isolation plate 7. The telescopic element 4 can be extended to a total length of 70 mm. The telescopic element 4 is preferably a telescopic cylinder, a hydraulic cylinder or the like. The action end of the telescopic element 4 is connected to the slider 5, so that the telescopic element 4 can drive the slider 5 to move back and forth. The size of the slider 5 is preferably 50 mm * 45 mm * 30 mm. The telescopic direction of the telescopic element 4 is perpendicular to the expansion direction of the baffle body 15. The isolation plate 7 is provided with a long hole, the length direction of which is consistent with the telescopic direction of the telescopic element 4. The upper end of the spring 6 is connected to the lower end of the slider 5, and the lower end of the spring 6 extends through the long hole to the bottom of the isolation plate 7 and is connected to the upper end of the impact block 8. The setting of the long hole can ensure that the slider 5 and the smooth movement of the impact block 8, the shortest length of the spring 6 is 20mm, and the natural length after release is 60mm. The size of the impact block 8 is 20mm*45mm*40mm, and the lower end of the impact block 8 contacts the upper end surface of the impact plate 10. At the same time, the upper end surface of the impact plate 10 is a smooth plane, and the elastic modulus of the spring 6 is large, that is, the spring 6 is harder, which can make the movement of the impact block 8 smoother. The telescopic element 4 can drive the impact block 8 to move toward the impact hole 9 through the slider 5 and the spring 6, and when the impact block 8 moves to the impact hole 9, it can extend through the impact hole 9 and act on the side wall of the box body to open the side wall of the box body. By real-time detection of the pressure in the tunnel, the opening of the side wall of the box body can be controlled in a linked manner, thereby facilitating the automatic deployment of the baffle body 15 and improving construction efficiency.

[0032] A toggle wheel 13 is rotatably mounted on the first side wall 21 of the box body, and a toggle block 23 is mounted on the outer edge of the toggle wheel 13. The toggle block 23 is located directly below the impact hole 9, and the toggle block 23 can drive the toggle wheel 13 to rotate. The toggle wheel 13 is preferably a circular gear, and the diameter of the toggle wheel 13 is 50 mm, the thickness is 45 mm, and the size of a single tooth is 20 mm * 45 mm * 20 mm. The center of the toggle wheel 13 is mounted at a distance of 45 mm from the impact hole 9 in the X direction and 25 mm in the Y direction. A hook 11 is further mounted on the outer edge of the toggle wheel 13 near the second side wall 22 of the box body. The first side wall 21 of the box body is adjacent to the second side wall 22 of the box body. The first side wall 21 of the box body is located near the hook 11 and The second side wall 22 of the box body is respectively provided with a hanging ring 12 at a position close to the hook 11, and the two hanging rings 12 can be aligned in the vertical direction. The hook 11 can pass through the two hanging rings 12 and make the first side wall 21 of the box body perpendicular to the second side wall 22 of the box body, and make the first side wall 21 of the box body block the baffle body 15. At this time, the baffle body 15 is stored in the box body in a folded state. When the telescopic element 4 is actuated, the impact block 8 extends through the impact hole 9 and impacts the toggle block 23 downward, which can drive the toggle wheel 13 to rotate until the hook 11 is disengaged from the two hanging rings 12. At this time, the baffle body 15 can push away the first side wall 21 of the box body and unfold along the length direction of the side of the tunnel to fit the rock wall of the side of the tunnel. During this process, an elastic connection can also be adopted between the first side wall 21 of the box body and the second side wall 22 of the box body. For example, the two can be connected by a torsion spring or other structure to ensure that after the hook 11 is separated from the hanging ring 12 (that is, the constraint between the first side wall 21 and the second side wall 22 is released), the two side walls can be rotated counterclockwise and clockwise respectively to open, making way for the release of the baffle body 15.

[0033] As a preferred solution of this embodiment, the hanging ring 12 is fixed to the first side wall 21 of the box body or the second side wall 22 of the box body through welding points.

[0034] The telescopic element 4 is connected to a signal receiver 3 for receiving the signal detected by the pressure detection element 1. The size of the signal receiver 3 is preferably 30mm*45mm*30mm. The pressure detection element 1 and the signal receiver 3 are connected by a wire 2. The length of the wire 2 is preferably 15000mm. When the pressure detection element 1 detects that the pressure reaches the set value, it can transmit the pressure signal to the signal receiver 3, and enable the signal receiver 3 to control the movement of the telescopic element 4, so as to automatically control the expansion of the baffle body 15 according to the actual pressure situation, thereby improving construction efficiency.

[0035] The baffle body 15 includes a plurality of folding parts connected in sequence, and the folding part includes a rotating element and a baffle unit. One end of the baffle unit is connected to the rotating element, and adjacent baffle units are connected by the rotating element to ensure that each baffle unit can rotate relative to each other, so as to facilitate the overall expansion of the baffle body 15. The rotating element in the folding part located at the first end is rotatably connected to an inner side wall of the box body to limit one end of the baffle body 15. The baffle unit in the folding part located at the second end can contact the other inner side wall of the box body, and then can block the baffle body 15 through the inner side wall of the box body, so as to ensure that the baffle body 15 is in a stored folded state when not in operation.

[0036] The baffle unit includes a robotic arm 18, an isolation cloth 19 and a sponge layer 20. In this embodiment, the size of the robotic arm 18 is preferably 120mm*10mm*10mm. One end of the robotic arm 18 in the baffle unit located at the second end is connected to the rotating element, and the other end of the robotic arm 18 in the baffle unit located at the second end is a free end and is used to contact the inner wall of the box body. The two ends of the robotic arms 18 in the remaining baffle units are respectively connected to two adjacent rotating elements. The isolation cloth 19 is laid on one side of the robotic arm 18, and the size of the isolation cloth 19 is 130mm*60mm. The sponge layer 20 is laid on the side of the robotic arm 18 in the yard where the isolation cloth 19 is, and the size of the sponge layer 20 is 130mm*40mm*60mm.

[0037] When the baffle body 15 is in a folded state, the distance between the upper rotating element and the lowest point of the toggle wheel 13 is 10 mm, the distance between the lower rotating element and the bottom surface of the box body is 10 mm, and the distance between the end of the rotating element and the inner wall of the box body is 10 mm, and the distance between the upper rotating element and the lower rotating element is 30 mm.

[0038] The rotating element includes a rotating shaft 14, an energy storage spring 17 and a rotating shell 16. The rotating shell 16 is a hollow cylindrical shell with a diameter of 20 mm and a wall thickness of 12 mm. The diameter of the rotating shaft 14 is 15 mm. When designed as a hollow shaft, the wall thickness is 12 mm. The rotating shaft 14 and the energy storage spring 17 are both located in the rotating shell 16, and the energy storage spring 17 extends along the circumference of the rotating shaft 14. The circumference of the rotating shell 16 is provided with a long hole for the rotation of the robot arm 18. One end of the energy storage spring 17 in the baffle unit at the first end is connected to the inner wall of the box body. The other end of the energy storage spring 17 in the baffle unit at the first end is connected to one end of a mechanical arm 18. The two ends of the energy storage springs 17 in the remaining baffle units are respectively connected to one end of two adjacent mechanical arms 18. One end of the mechanical arm 18 in the baffle unit at the second end is connected to the rotating shaft 14, and the other end of the mechanical arm 18 in the baffle unit at the second end is a free end. The mechanical arms 18 in the remaining baffle units have one end connected to the rotating shaft 14 and the other end connected to the rotating housing 16. When the baffle body 15 is in the folded state, each energy storage spring 17 is in a stretched state. When the sidewalls of the box body no longer block the free end of the baffle body 15, the baffle body 15, under the action of the energy storage springs 17 in each rotating element, automatically drives each mechanical arm 18 to rotate until the mechanical arm 18 contacts the rock wall, achieving the deployment action. After the robotic arm 18 is deployed into place, it cannot completely fit the rock wall. However, when the filling body submerges the isolation cloth 19, it will apply pressure to the isolation cloth 19 and the sponge layer 20, causing them to automatically fit tightly against the rock wall, thereby preventing the filling body slurry from leaking.

[0039] The pressure detection element 1 is a pressure sensor.

[0040] The filling baffle device capable of automatically unfolding and actively fitting the side of the lane provided in this embodiment can be provided in two sets when used, installed on the left and right sides of the lane respectively, and the filling baffle devices capable of automatically unfolding and actively fitting the side of the lane on the left and right sides are mirror-symmetrical.

[0041] The filling baffle device provided in this embodiment, which can automatically unfold and actively fit the side of the tunnel, can realize the automatic laying of isolation cloth 19 and sponge layer 20 through the above-mentioned design, without the need for workers to stop filling and then lay, thus shortening the construction time by more than 20%, and greatly improving the construction efficiency; and, after the baffle body 15 is unfolded, the self-weight stress of the filling body can make the isolation cloth 19 and sponge layer 20 fit better with the surrounding rock of the tunnel, which is more efficient and has better effects than the traditional hay + isolation patch.

[0042] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention.
