Description

Technical Field

[0001] This invention relates to the field of support device technology, specifically to a roadway corner co-support steel frame support device. Background Technology

[0002] In underground engineering, tunnels are artificial passages excavated to achieve purposes such as transportation, ventilation, drainage, or mining. They are one of the core infrastructures for underground space development. The tunnel sidewalls are the junctions between the sidewalls and the roof or the sidewalls and the floor in the tunnel structure. They are key stress nodes in underground tunnels and weak areas that need to be focused on in support design.

[0003] When supporting roadways, a steel frame is typically used as the foundation. Side plates are installed on the steel frame, and these side plates are fitted against the inner wall of the roadway for fixation. The junction of the roadway's support and the floor is a region of concentrated stress in the surrounding rock. High stress can lead to rock failure and roadway instability, necessitating support for the floor and side walls. This is usually achieved by controlling the position of the support plates on the side plates to ensure they fit snugly against the roadway's floor and side walls, thus providing support.

[0004] However, the conditions of the bottom and side corners are different in different roadways, or the bottom and side corners at different locations in the same roadway may also be different. Some bottom and side corners may be right angles, while others may be arcs. The support plates of most existing support devices have relatively simple shapes, making it difficult to modularly adjust the support plates according to the conditions of different side corners. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a roadway corner-coordinated load-bearing steel frame support device, which solves the problem mentioned in the background art of the difficulty in modularly adjusting the support plate for different roadway corners.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A roadway corner support device with a steel frame includes a base plate and side plates mounted on the base plate. The side plates have several through slots on their sides. The device also includes right-angle plates, arc-shaped plates, a top plate assembly, and a pushing assembly. Several right-angle plates are slidably mounted on the base plate. Each right-angle plate has a through slot on its side, and a fitting plate is hinged to the slot. A connecting frame is fixedly mounted on the side of each right-angle plate. Several arc-shaped plates are slidably mounted on the top of each right-angle plate, and a connecting frame is fixedly mounted between the arc-shaped plates. Several top plate assemblies are provided, each located on the side of one of the right-angle plates, for fixing the right-angle plates and arc-shaped plates when they fit against the roadway corner. The pushing assembly is located on the base plate and is used to drive the right-angle plates and arc-shaped plates to fit against the roadway corner.

[0010] Furthermore, the top plate assembly includes a support plate, a rotating frame, support plates, and a push-forward assembly. The support plate is rotatably mounted on the top of the right-angle plate, the rotating frame is rotatably mounted on the side of the right-angle plate, two support plates are fixedly mounted on the top of the support plate, and the push-forward assembly is disposed on the rotating frame.

[0011] Furthermore, the forward push assembly includes a forward push cylinder, a threaded rod, and a handwheel. The forward push cylinder is slidably mounted inside the rotating frame. One end of the threaded rod is fixedly mounted on the side of the forward push cylinder and threadedly mounted on the side of the rotating frame. The handwheel is coaxially connected to the threaded rod.

[0012] Furthermore, the pushing assembly includes a support cover, a reciprocating screw, a second handwheel, a pushing frame, and a pushing component. The support cover is fixedly installed on the base plate, the reciprocating screw is rotatably installed inside the support cover, and a matching crescent-shaped slider is installed on the reciprocating screw. The second handwheel is coaxially connected to the reciprocating screw. One end of the pushing frame is fixedly connected to the side of the crescent-shaped slider, and the other end of the pushing frame is fixedly connected to the side of the first connecting frame. The pushing component is disposed on the first connecting frame.

[0013] Furthermore, the pushing assembly includes a pushing frame and a fixing rod. The pushing frame is slidably mounted on the side of the pushing frame, and the fixing rod is fixedly mounted between the pushing frame and the connecting frame.

[0014] Furthermore, the inner wall of the support cover is provided with a sliding groove, a limiting block is slidably installed in the sliding groove, and the limiting block is fixedly connected to the side of the crescent-shaped slider.

[0015] Furthermore, the arc-shaped plate corresponds one-to-one with the through slots of the plurality of right-angled plates.

[0016] Furthermore, the side of the base plate is set in a pointed cone shape, and the side of the side plate is provided with several anchor holes.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a roadway corner collaborative bearing steel frame support device, which has the following beneficial effects:

[0019] 1. In this invention, when the sidewalls and bottom corners of the tunnel are fitted and supported, the side of the bottom plate is first inserted into the bottom side of the tunnel, and the side plate is fitted to the side of the tunnel. At this time, the fitting of the right-angle plate or the arc plate can be adjusted according to the state of the bottom corner of the tunnel.

[0020] 2. In this invention, when the bottom and side corners of the tunnel are regular right angles, the right-angle plate can be pushed to fit against the side and bottom corners of the tunnel by the cooperation between the pushing component and the roof plate component, thereby providing support for them;

[0021] 3. In this invention, when the bottom corner of the tunnel is arc-shaped, the right-angle plate can be moved backward by pushing the component, and the arc-shaped plate can be moved forward through the through groove of the right-angle plate to fit the arc-shaped bottom corner of the tunnel, thereby fitting the bottom corner of the tunnel.

[0022] Therefore, the roadway corner co-support steel frame support device, through the cooperation between the right-angle plate, the arc plate, the top plate assembly and the pushing assembly, can adjust the right-angle plate or the arc plate at any time according to the state of the roadway bottom corner when supporting the roadway.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 8 A steel frame support device for roadway corner joint bearing includes a base plate 1 and side plates 2 installed on the base plate 1. The side plates 2 have several through slots on their sides. The device also includes right-angle plates 3, arc plates 6, top plate components, and a pushing component. Several right-angle plates 3 are slidably installed on the base plate 1. The side plates 3 have through slots, and fitting plates 4 are hinged to the slots. Connecting frames 1 5 are fixedly installed on the side plates 3. Several arc plates 6 are slidably installed on the tops of the right-angle plates 3, and connecting frames 2 7 are fixedly installed between the arc plates 6. Several top plate components are provided, and the top plate components are respectively provided on the side plates of the right-angle plates 3 to fix them when the right-angle plates 3 and arc plates 6 fit against the roadway corner. The pushing component is provided on the base plate 1 to drive the right-angle plates 3 and arc plates 6 to fit against the roadway corner.

[0034] like Figure 7 As shown, when supporting the roadway, because the side of the bottom plate 1 is set as a pointed cone and the side of the side plate 2 is provided with several anchor holes, the device can be placed into the roadway, and the pointed cone of the bottom plate 1 is inserted into the side wall of the roadway. Then, the anchor cable passes through the anchor hole of the side plate 2 to further strengthen the bonding strength between the side plate 2 and the side of the roadway.

[0035] like Figure 2 , Figure 3 , Figure 6 and Figure 8As shown, after the bonding is completed, the state of the bottom corner of the tunnel (whether it is a right angle or an arc angle) can be observed. If it is a right angle, the connecting frame 5 and several right-angle plates 3 can be moved forward by the pushing component, passing through the through groove of the side plate 2, thereby bonding and supporting the side wall of the tunnel. After bonding is completed, it can be fixed by the top plate component. The pushing component includes a support cover 14, a reciprocating screw 15, a handwheel 17, a pushing frame 18, and a pushing component. The support cover 14 is fixedly installed on the bottom plate 1. The reciprocating screw 15 is rotatably installed in the support cover 14, and a matching crescent slider 16 is installed on the reciprocating screw 15. The handwheel 17 is coaxially connected to the reciprocating screw 15. One end of the pushing frame 18 is fixedly connected to the side of the crescent slider 16, and the other end of the pushing frame 18 is fixedly connected to the side of the connecting frame 5. Next, the pushing assembly is set on the connecting frame 5. The pushing assembly includes a pushing frame 19 and a fixing rod 20. The pushing frame 19 is slidably installed on the side of the pushing frame 18. The fixing rod 20 is fixedly installed between the pushing frame 19 and the connecting frame 7. The top plate assembly includes a support plate 8, a rotating frame 9, a support plate 10 and a front pushing assembly. The support plate 8 is rotatably installed on the top of the right angle plate 3. The rotating frame 9 is rotatably installed on the side of the right angle plate 3. Two support plates 10 are fixedly installed on the top of the support plate 8. The front pushing assembly is set on the rotating frame 9. The front pushing assembly includes a front pushing cylinder 11, a threaded rod 12 and a handwheel 13. The front pushing cylinder 11 is slidably installed inside the rotating frame 9. One end of the threaded rod 12 is fixedly installed on the side of the front pushing cylinder 11 and the threaded rod 12 is threadedly installed on the side of the rotating frame 9. The handwheel 13 is coaxially connected to the threaded rod 12.

[0036] like Figure 4 and Figure 5 As shown, specifically, rotating handwheel 17 causes the reciprocating screw 15 to rotate within the support cover 14, allowing the crescent-shaped slider 16 to move back and forth on the reciprocating screw 15. It should be noted that the shape of the crescent-shaped slider 16 matches the helical groove of the reciprocating screw 15. When the reciprocating screw 15 rotates, the sidewall of the helical groove exerts an axial thrust on the crescent-shaped slider 16 embedded within it. This is because the inner sidewall of the support cover 14 has a sliding groove, within which a limit block 21 is slidably installed, and the limit block 21 and the crescent... The side of the slider 16 is fixedly connected, so the crescent slider 16 can only move along the axial trajectory of the reciprocating screw 15, thereby moving back and forth. When the crescent slider 16 reaches the end of the reciprocating screw 15, the crescent slider 16 will smoothly transition to the reverse spiral groove, thereby realizing reciprocating movement. This is a well-known technology and will not be described in detail. The crescent slider 16 drives the pusher frame 18 to move forward, the pusher frame 18 drives the connecting frame 5 to move forward, and the connecting frame 5 drives several right-angle plates 3 to move forward to the through groove and fit as close as possible to the bottom corner of the tunnel.

[0037] After the bonding is completed, the support plate 8 can be rotated to a position horizontal with the through groove, and then the rotating frame 9 can be rotated. It should be noted that the top of the support plate 10 has a groove that fits with the bottom of the rotating frame 9. When the rotating frame 9 is placed into the groove of the support plate 10, the rotating frame 9 and the support plate 8 restrict each other. The handwheel 13 can be rotated, and the handwheel 13 drives the threaded rod 12 to move forward in the rotating frame 9. Simultaneously, it drives the front push cylinder 11 to rotate and move forward in the rotating frame 9, thereby pressing against the bonding plate 4 of the right angle plate 3, preventing the bonding plate 4 from rotating due to the hinge and allowing the bonding plate 4 to fit against the side wall of the tunnel.

[0038] like Figure 2 , Figure 4 and Figure 6 As shown, if the bottom corner of the tunnel is arc-shaped, the right-angle plate 3 can be moved backward by rotating the second handwheel 17 again, and then the bonding plates 4 can be opened one by one. At this time, the support plate 8 is rotated to a position perpendicular to the through groove of the right-angle plate 3, and then the rotating frame 9 is rotated to the other end. Then, the pushing frame 19 is pushed forward on the pushing frame 18. Under the connection of the fixed rod 20, the connecting frame 7 and several arc-shaped plates 6 are moved forward. Because if the arc-shaped plates 6 correspond one-to-one with the through grooves of several right-angle plates 3, then the several arc-shaped plates 6 pass through the through grooves of the right-angle plates 3, and then approach and fit against the bottom corner of the tunnel. Then, the support plate 8 and the rotating frame 9 are rotated back to the initial position. Then, the first handwheel 13 is rotated, and the threaded rod 12 and the front push cylinder 11 are rotated forward on the rotating frame 9 to contact and fit against the side of the arc-shaped plate 6 as much as possible, thereby fixing it against it.

[0039] Working principle: When this roadway corner support steel frame support device is used to support the roadway, the device is first placed into the roadway, and the pointed cone of the bottom plate 1 is inserted into the side wall of the roadway. Then, the anchor cable passes through the anchor hole of the side plate 2 to further strengthen the fit between the side plate 2 and the side of the roadway. After the fit is completed, the right angle plate 3 or the arc plate 6 is adjusted according to the state of the roadway corner. The handwheel 17 is turned, and the handwheel 17 drives the reciprocating screw 15 to rotate in the support cover 14. The crescent slider 16 can move back and forth on the reciprocating screw 15. The crescent slider 16 drives the push frame 18 to move forward, the push frame 18 drives the connecting frame 5 to move forward, and the connecting frame 5 drives several right angle plates 3 to move forward to the through groove to fit the roadway corner to the maximum extent.

[0040] After bonding is completed, rotate the support plate 8 to a position level with the through groove, and then rotate the rotating frame 9 to place the rotating frame 9 into the groove of the support plate 10. At this time, the rotating frame 9 and the support plate 8 restrict each other, and the handwheel 13 can be rotated. The handwheel 13 drives the threaded rod 12 to move forward in the rotating frame 9, and simultaneously drives the front push cylinder 11 to rotate and move forward in the rotating frame 9, thereby pressing against the bonding plate 4 of the right angle plate 3, preventing the bonding plate 4 from rotating due to the hinge and allowing the bonding plate 4 to adhere to the side wall of the tunnel.

[0041] If the bottom corner of the tunnel is arc-shaped, the right-angle plate 3 can be moved backward by rotating the second handwheel 17 again, and then the bonding plates 4 can be opened one by one. At this time, the support plate 8 is rotated to a position perpendicular to the through groove of the right-angle plate 3, and then the rotating frame 9 is rotated to the other end. Then, the pusher 19 is pushed forward on the connecting frame 5. Under the connection of the fixed rod 20, the connecting frame 7 and several arc-shaped plates 6 are moved forward. Several arc-shaped plates 6 pass through the through groove of the right-angle plate 3, and then approach and fit against the bottom corner of the tunnel. The position of the front pusher 11 is adjusted again to fit against the side of the arc-shaped plate 6, and it is fixed and stabilized.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
