Description

Technical Field

[0001] This utility model relates to the field of tunnel support technology, and more specifically, to a tunnel support device. Background Technology

[0002] Currently, in the mining industry, the construction technology and preparation for rapid tunneling have been greatly improved, resulting in increased annual output and a significant improvement in rapid tunneling speed. There are now onboard temporary support devices for tunneling machines to provide temporary support along with the tunneling face, immediately supporting the roof, preventing further deformation of the rock strata, and ensuring the safety of personnel and equipment.

[0003] The existing support system mainly consists of a lifting column, a support beam, a top beam, and a telescopic pipe. The lifting column is responsible for adjusting the height of the system, the support beam is located at the top of the lifting column, and the top beam is installed above the support beam. This system only allows for overall lifting and lowering of the roadway roof, and cannot compensate for local unevenness. When the roadway roof experiences undulations, grooves, or localized rises, point contact or even a gap in the roof can easily form between the support surface and the rock surface, resulting in uneven distribution of support force and poor support effectiveness. Utility Model Content

[0004] This utility model provides a roadway support device to solve the problem that the support height of the roadway roof in the prior art can only achieve overall lifting and lowering. When the roadway roof is uneven, it cannot compensate for the difference in local concavity and convexity, resulting in uneven distribution of support force and poor support effect.

[0005] This utility model provides a roadway support device, comprising: an installation structure having a support end and an installation end arranged opposite each other in the vertical direction, the support end being used to abut against the floor of the roadway; a support structure including multiple rotating parts, the multiple rotating parts being rotatably arranged on the installation end in the horizontal direction, the rotation axis of the installation structure forming an angle with the vertical direction, the rotating parts being used to support the roof of the roadway; and multiple adjusting parts disposed between the installation structure and the rotating parts, the multiple adjusting parts being arranged one-to-one with the multiple rotating parts, the rotating parts being rotatably connected to the adjusting parts, the adjusting parts having a connecting end and an adjusting end, the connecting end being connected to the installation end, the adjusting end being connected to the rotating parts, and the adjusting end being able to move relative to the connecting end in the vertical direction to adjust the distance between the rotating parts and the installation structure.

[0006] Furthermore, the adjustment section includes two adjustment units, which are respectively arranged one-to-one with the two ends of the rotating part, and the two adjustment units are spaced apart on the mounting end.

[0007] Furthermore, the adjustment unit includes: a sleeve having a cavity, a guide groove on the side wall of the sleeve communicating with the cavity, one end of a rotating member being rotatably inserted into the guide groove and moving along the guide groove; and an elastic member disposed in the cavity, one end of the elastic member being fixedly connected to the bottom of the sleeve, and one end of the rotating member being connected to the end of the elastic member away from the bottom of the sleeve.

[0008] Furthermore, the rotating component includes a rotating roller and a rotating shaft. The rotating shaft passes through the rotating roller and extends out from both ends of the rotating roller. Both ends of the rotating shaft are rotatably inserted into the guide grooves of the two adjusting units. The guide grooves extend vertically and the width of the guide grooves is greater than the outer diameter of the rotating shaft.

[0009] Furthermore, the outer periphery of the rotating roller is provided with multiple anti-slip structures at intervals.

[0010] Furthermore, the adjustment unit also includes a movable plate, which is disposed in the cavity. The side of the movable plate closer to the mounting structure is connected to the elastic element, and the side of the movable plate away from the mounting structure abuts against one end of the rotating element.

[0011] Furthermore, the support structure also includes a flexible belt that covers multiple rotating components. The flexible belt abuts against the roof of the tunnel, and the rotating components can roll relative to the flexible belt.

[0012] Furthermore, the mounting structure has two baffles on its sidewalls that are arranged opposite each other along the distribution direction of multiple rotating parts. The top of the baffles has a support surface, the two support surfaces are arranged facing each other, the height of the support surfaces is between the highest and lowest points of the support structure, and there is a gap between the support surfaces and the support structure.

[0013] Furthermore, the mounting structure includes a support frame and a base, with the base located at the bottom of the support frame, the top of the support frame forming an mounting end, and the bottom of the base forming a support end; the support frame includes a support plate structure, a support column structure, and a reinforcing structure, with the support plate structure and the support column structure arranged alternately, and the reinforcing structure located between the support plate structure and the support column structure.

[0014] Furthermore, two handrail structures are provided on the sidewalls of the mounting structure that are arranged opposite each other along the distribution direction of the multiple rotating parts.

[0015] By integrating multiple rotating components into a support structure, the design of these rotating components transforms the hard friction between the support structure and the tunnel roof into rotational friction, reducing friction and improving the support effect. Furthermore, the rotating components can not only support the tunnel roof but also transport materials and other items within the tunnel. Multiple adjustment sections are provided, each corresponding to one of the rotating components. Each adjustment section has a connecting end and an adjusting end. The connecting end connects to the mounting end, and the adjusting end abuts against the rotating component. The adjusting end can move vertically relative to the connecting end to adjust the distance between the rotating component and the mounting structure, thereby adjusting the distance between the rotating component and the tunnel roof, i.e., adjusting the support height of the rotating component. This configuration allows for unified adjustment of the support height of multiple rotating components through multiple adjustment sections. When the roadway roof experiences undulations, grooves, or localized rises, the support height of different rotating components can be adjusted individually based on the degree of undulation of the roof surface. This provides differential compensation for localized unevenness in the roadway roof, ensuring a more uniform distribution of the support force and improving the support effect of the roadway support device.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] like Figures 1 to 5 As shown, this utility model embodiment provides a roadway support device, which includes: an installation structure 10, a support structure 20, and multiple adjustment parts 30. The installation structure 10 has a support end 101 and an installation end 102 arranged opposite each other in the vertical direction. The support end 101 is used to abut against the floor of the roadway. The support structure 20 includes multiple rotating members 21, which are rotatably mounted on the installation end 102 and distributed in the horizontal direction. The rotation axis of each rotating member 21 forms an angle with the vertical direction, and the rotating member 21 is used to support the roof of the roadway. Multiple adjustment parts 30 are disposed between the installation structure 10 and the rotating members 21, with each adjustment part 30 corresponding to one of the rotating members 21. The rotating members 21 are rotatably connected to the adjustment parts 30. Each adjustment part 30 has a connecting end and an adjusting end. The connecting end is connected to the installation end 102, and the adjusting end is connected to the rotating member 21. The adjusting end can move vertically relative to the connecting end to adjust the distance between the rotating member 21 and the installation structure 10.

[0035] The specific structure of the adjusting part 30 is not limited; it can be a telescopic cylinder, a hydraulic cylinder, an elastic structure, or other structures that can achieve height adjustment. The specific location of the adjusting part 30 is also not limited; it can be installed alone at the bottom of the rotating member 21, or multiple parts can be distributed at both ends of the rotating member 21.

[0036] The rotating component 21 can be a cylindrical structure that can rotate, such as a drum, a rotating shaft, or a rotating roller.

[0037] By applying the technical solution of this utility model, multiple rotating parts 21 are integrated into a support structure. The design of the rotating parts 21 can convert the hard friction between the support structure 20 and the tunnel roof into rotational friction, reducing friction and improving the support effect. At the same time, the rotating parts 21 can not only be used to support the tunnel roof, but also to transport materials and other items inside the tunnel. Multiple adjusting parts 30 are provided, each corresponding to one of the rotating parts 21. Each adjusting part 30 has a connecting end and an adjusting end. The connecting end is connected to the mounting end, and the adjusting end abuts against the rotating part 21. The adjusting end can move vertically relative to the connecting end to adjust the distance between the rotating part 21 and the mounting structure, thereby adjusting the distance between the rotating part 21 and the tunnel roof, i.e., adjusting the support height of the rotating part 21. This configuration allows for unified adjustment of the support height of multiple rotating components 21 through multiple adjustment sections. When the roadway roof experiences undulations, grooves, or localized rises, the support height of different rotating components 21 can be adjusted individually based on the degree of undulation of the roof surface. This provides differential compensation for localized unevenness in the roadway roof, ensuring a more uniform distribution of the support force of the support structure 20 and improving the support effect of the roadway support device.

[0038] like Figure 2 As shown, the adjustment unit 30 includes two adjustment units 31, each corresponding to one end of the rotating member 21. The adjustment units 31 are used to adjust the support height of the rotating member 21. The two adjustment units 31 are spaced apart on the mounting end 102. Compared to adjusting the support height of the rotating member using only a single adjustment structure, using two adjustment units 31 ensures that both ends of the rotating member 21 can move, reducing the possibility of one end moving while the other cannot be adjusted. This further improves the uniformity of support and enhances the stability and accuracy of the support height adjustment of the rotating member 21.

[0039] In other embodiments, the adjustment unit 30 may also include multiple (two or more) or a single adjustment unit 31, which can be selected according to the actual working conditions.

[0040] like Figure 3As shown, the adjustment unit 31 includes a sleeve 310 and an elastic element 311. The sleeve 310 has a cavity, and its side wall has a guide groove 3101 communicating with the cavity. One end of the rotating element 21 is rotatably inserted into the guide groove 3101 and moves along it. The other end of the rotating element 21 is rotatably inserted into the guide groove 3101 of another adjustment unit 31 and moves along it. Thus, the guide groove 3101 guides the movement of the rotating element 21, preventing it from shifting and interfering with or colliding with adjacent rotating elements when adjusting its support height, thereby improving the stability of the rotating element 21's movement and support. The elastic element 311 is disposed within the cavity, and one end of the elastic element 311 is fixedly connected to the bottom of the sleeve 310, forming a connecting end at the bottom of the sleeve 310. One end of the rotating component 21 is connected to the end of the elastic component 311 furthest from the bottom of the sleeve 310, so as to adjust the height of the end of the rotating component 21. The end of the elastic component 311 furthest from the bottom of the sleeve 310 forms an adjustment end. With this configuration, the elastic component 311 can adjust the support height of the rotating component 21 at any time according to the unevenness of the contact surface of the roadway roof. When the rotating component 21 supports the roadway roof, the elastic component 311 is compressed to provide support force. When the height of the roadway roof is low, the compression of the elastic component 311 in the corresponding adjustment unit 31 increases; when the height of the roadway roof is high, the compression of the elastic component 311 in the corresponding adjustment unit 31 is small. No manual adjustment of the support height of the rotating component 21 is required, simplifying the operation of the support device.

[0041] In other embodiments, the adjustment unit 31 can be configured as a hydraulic cylinder or an electric telescopic rod, etc. The end of the adjustment unit 31 is rotatably connected to the end of the rotating member 21 to drive the rotating member 21 to rise or fall, and the raising and lowering of the rotating member 21 is controlled by an electronic control system.

[0042] Among them, the elastic element 311 can be set as a spring, elastic bellows or other elastic structure.

[0043] In this embodiment, the elastic element 311 is a spring.

[0044] like Figure 3 As shown, the adjustment unit 31 also includes a movable plate 312, which is movably disposed within the cavity. The side of the movable plate 312 closest to the mounting structure 10 is fixedly connected to the end of the elastic member 311, and the side of the movable plate 312 furthest from the mounting structure 10 abuts against one end of the rotating member 21. One end of the rotating member 21 is placed on the side of the movable plate 312 furthest from the mounting structure 10. This increases the contact area between the adjustment unit 31 and the rotating member 21, reduces the shaking of the rotating member 21 during movement, and improves the stability of the adjustment unit 31 in adjusting the height of the rotating member 21.

[0045] In this embodiment, the sleeve 310 is a cylindrical tube and the movable plate 312 is a circular plate, which are adapted to the structure of the sleeve 310. In this way, the sleeve 310 can guide the movement of the movable plate 312, prevent the movable plate 312 from flipping during movement, and ensure the stability and smoothness of the support for the rotating part 21.

[0046] In other embodiments, the sleeve 310 can be a cuboid cylinder or other structure. The movable plate 312 can be a square plate or other structure.

[0047] Specifically, the rotating component 21 includes a rotating roller 211 and a rotating shaft 212. The rotating shaft 212 passes through the rotating roller 211 and extends out from both ends of the rotating roller 211. Both ends of the rotating shaft 212 are rotatably inserted into the guide grooves 3101 of the two adjusting units 31. The rotating roller 211 and the rotating shaft 212 rotate synchronously. The guide groove 3101 extends vertically, and its width is greater than the outer diameter of the rotating shaft 212. Thus, while the rotating shaft 212 rotates within the guide groove 3101, it can also achieve a small-amplitude rolling motion along the width of the guide groove. This transforms the rotational friction between the rotating component 21 and the roadway roof into rolling friction, further reducing the friction between the rotating roller 211 and the external contact surface when the roadway support device moves or when the rotating component 21 rotates, thereby extending the service life of the roadway support device.

[0048] In this application, the rotating roller 211 and the rotating shaft 212 extend horizontally. The rotation axis of the rotating roller 211 extends horizontally and is the same as the length direction of the rotating roller 211. The length direction of the rotating roller 211 is the extension direction and length direction of the rotating member 21. Multiple rotating rollers 211 are distributed at intervals in the horizontal direction, and the distribution direction is perpendicular to the length direction of the rotating roller 211.

[0049] like Figure 2 As shown, multiple anti-slip structures 2112 are spaced apart on the outer periphery of the rotating roller 211. The anti-slip structures 2112 extend along the length of the rotating roller 211, which can increase the friction of the rotating roller 211 when it is stationary or performing support work, and prevent rotation from affecting the support effect.

[0050] Specifically, the anti-slip structure 2112 is a groove.

[0051] like Figure 1As shown, the support structure 20 also includes a flexible belt 22, which covers multiple rotating components 21. The flexible belt 22 abuts against the roof of the tunnel, and the rotating components 21 can roll relative to the flexible belt 22. The flexible belt 22 makes the supporting force provided by the support structure 20 more moderate, avoiding impact or shock to the roof when the rotating components 21 support the tunnel roof, which could lead to roof collapse or damage. This ensures the integrity of the tunnel roof while providing support. Simultaneously, the flexible belt can also collect stones and other debris falling from the tunnel roof, preventing them from falling between the rotating components 21 inside the tunnel support device or inside the installation structure 10, thus preventing component jamming. Furthermore, the flexible belt 22 can also be used to place items to be transported.

[0052] In this embodiment, the flexible belt is a flexible track that extends along the distribution direction of the rotating component 21 and is longer than the length of the roadway support device. In use, multiple roadway support devices can be used in a coordinated manner along the extension direction of the flexible belt to carry out long-distance support work.

[0053] like Figure 1 As shown, the mounting structure 10 has two baffles 40 on its sidewalls, which are arranged opposite each other along the distribution direction of the multiple rotating parts 21. Each baffle 40 has a support surface 401 on its top. The two support surfaces 401 face each other, and their height is between the highest and lowest points of the support structure 20. A gap exists between the support surface 401 and the support structure 20 to prevent interference between the baffles 40 and the rotating parts 21. This gap is not limited and can be adjusted according to the thickness of the flexible strip 22 or the working conditions. Through this arrangement, the support surface 401 provides a stopping function on one side of the support structure 20. Since its height is between the highest and lowest points of the support structure 20, when the portion of the top flexible strip 22 outside the roadway support device sinks, the support surface 401 can support the falling portion of the flexible strip 22, preventing it from being pulled into the bottom of the support structure 20 by the rotating parts 21, thus ensuring the normal operation of the device.

[0054] Specifically, the baffle 40 is a U-shaped plate with the opening facing the inside of the device. The bottom end of the U-shaped plate is fixedly connected to the side wall of the mounting structure 10, and the top end of the U-shaped plate forms a support surface 401.

[0055] like Figure 1 As shown, the mounting structure 10 includes a support frame and a base 19. The base 19 is located at the bottom of the support frame, the top of the support frame forms a mounting end 102, and the bottom of the base 19 forms a support end 101. The support frame includes a support plate structure, a support column structure, and a reinforcing structure. The support plate structure and the support column structure are staggered, and the reinforcing structure is located between the support plate structure and the support column structure. The reinforcing structure can improve the overall structural strength of the support frame. Specifically, the support plate structure, the support column structure, and the reinforcing structure can be fixed together by welding.

[0056] Specifically, the specific structure of the base 19 is not limited; it can be a combination of support legs, angle steel brackets, and pads, as long as it can achieve a stable support function.

[0057] In this embodiment, two sets of support column structures and reinforcing structures are respectively provided and are spaced apart on the support plate structure along the length direction of the rotating member 21.

[0058] like Figure 1 As shown, the support plate structure includes an upper fixing plate 11, a middle fixing plate 12, and a lower fixing plate 13 arranged sequentially and at intervals along the vertical direction. The upper fixing plate 11 is located above the middle fixing plate 12 and the lower fixing plate 13. The top of the upper fixing plate 11 forms the mounting end 102, and the bottom of the lower fixing plate 13 is provided with multiple bases 19 at intervals. The support column structure includes multiple upper fixing columns 14 and multiple middle fixing columns 15. The multiple upper fixing columns 14 are arranged horizontally and at intervals between the upper fixing plate 11 and the middle fixing plate 12, and the multiple middle fixing columns 15 are arranged horizontally and at intervals between the middle fixing plate 12 and the lower fixing plate 13.

[0059] The reinforcing structure includes an upper tripod 161, a middle tripod 162, fixing rods 163, arched cylinders 17, and diagonal bracing plates 18. In this embodiment, four upper fixing columns 14 are arranged between the upper fixing plate 11 and the middle fixing plate 12, forming three hollow areas. Two arched cylinders 17 are arranged in the middle hollow area, and an upper tripod 161 is arranged in each of the two hollow areas on both sides. Six middle fixing columns 15 are arranged between the middle fixing plate 12 and the lower fixing plate 13, forming five hollow areas. A middle tripod 162 is arranged in the middle hollow area, and two cross-distributed fixing rods 163 are arranged inside the middle tripod 162. A diagonal bracing plate 18 is arranged in each of the four hollow areas on both sides.

[0060] In other embodiments, the specific distribution location and number of the above-mentioned reinforcing structures are not limited, as long as they can form a stable support.

[0061] like Figure 1 As shown, the installation structure 10 has two handrail structures 50 on its side wall, which are arranged opposite to each other along the distribution direction of the multiple rotating parts 21. Specifically, the handrail structures 50 are set on the central fixed column 15. The handrail structures 50 facilitate the movement or transport of the roadway support device by the staff.
