Technical Field

[0001] The utility model relates to the technical field related to support construction engineering, in particular to a device for adjusting the flatness of shotcrete for support. Background Technique

[0002] Tunnel engineering includes sub-projects such as primary support, waterproofing and drainage, and secondary lining. Among them, the primary support is an important part of tunnel engineering, and the quality control of shotcrete construction is the key and difficult point of primary support construction, especially the thickness of the shotcrete protective layer and the surface flatness are difficult to control.

[0003] The existing patent (publication number: CN214196346U) discloses a device for adjusting the flatness of shotcrete for primary support of tunnels, including an adjustment mechanism. The adjustment mechanism includes a scraper, a longitudinal rod, an upper hoop and a lower hoop. Longitudinal rods are fixedly installed on the lower surface of the scraper near the left and right edges. However, this technical solution still has deficiencies, as follows:

[0004] This device forms an adjustment mechanism by welding the longitudinal rod, the upper hoop and the lower hoop together, and then installs the adjustment mechanism on the nozzle of the wet shotcreting manipulator. Then, the flatness of the concrete is adjusted through the scraper. However, when the device is no longer in use, the operator needs to store the device. However, after the device is assembled, it occupies a large space and is difficult to disassemble, which is not convenient for the operator to store the device. For this reason, we propose a device for adjusting the flatness of shotcrete for support to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and the title of the utility model of the specification, to avoid obscuring the purpose of this part, the abstract of the specification and the title of the utility model. However, such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] Therefore, the purpose of the utility model is to provide a device for adjusting the flatness of shotcrete for support, which can solve the problem that when the existing device is no longer in use, the operator needs to store the device. However, after the device is assembled, it occupies a large space and is difficult to disassemble, which is not convenient for the operator to store the device.

[0007] To solve the above technical problems, the present utility model provides a device for adjusting the flatness of shotcrete for support, adopting the following technical solutions: It includes a connection mechanism, which includes two clamps. The outer walls of the two clamps are connected by arranging a plurality of connecting plates. A wet shotcreting manipulator nozzle is movably inserted into the two clamps. A driving ring is rotatably arranged inside the clamp. A first limiting member is movably arranged outside the clamp. One end of the first limiting member is inserted into the clamp and abuts against the outer wall of the driving ring. The other end of the first limiting member is movably inserted into the connecting plate. A second limiting member is movably arranged inside the clamp. One end of the second limiting member is inserted into the clamp and abuts against the inner wall of the driving ring. The other end of the second limiting member abuts against the outer wall of the wet shotcreting manipulator nozzle;

[0009] By adopting the above technical solutions, in this solution, first, the two clamps are connected together by four connecting plates, then the wet shotcreting manipulator nozzle is inserted into the clamp. Then the driving ring is rotated and the first limiting member is pushed to move. At this time, the first limiting member is inserted into the connecting plate, thereby fixing the connecting plate on the clamp. On the contrary, when the operator rotates the driving ring in the reverse direction, the first limiting member loses the thrust and resets and separates from the connecting plate, thus facilitating the operator to disassemble and store the device.

[0010] Optionally, a concave plate opposite to the connecting plate is fixedly arranged on the outer wall of the clamp. The connecting plate is movably inserted into the concave plate.

[0011] By adopting the above technical solutions, in this solution, it is convenient to connect the two clamps together when the connecting plate is inserted into the clamp.

[0012] Optionally, limiting plates are fixedly arranged on both outer walls of the connecting plate. The limiting plates are movably inserted into the inner wall of the concave plate.

[0013] By adopting the above technical solutions, in this solution, it is convenient to limit the connecting plate through the limiting plates, so that the connecting plate can only move along the inner wall of the concave plate, and it is convenient to fix the connecting plate in the concave plate by inserting the first limiting member into the connecting plate.

[0014] Optionally, an annular groove is opened inside the clamp. The driving ring is movably arranged in the annular groove. An arc-shaped groove is opened on the top surface of the clamp. The arc-shaped groove is communicated with the annular groove.

[0015] By adopting the above technical solutions, in this solution, it is convenient to assemble the driving ring through the annular groove, and it is convenient to control the movement of the first limiting member and the second limiting member by rotating the driving ring.

[0016] Optionally, a plurality of depressions are provided on both the outer wall and the inner wall of the driving ring. A connecting cylinder is fixedly provided on the top surface of the driving ring, and the connecting cylinder is movably arranged in the arc-shaped groove.

[0017] By adopting the above technical solution, the connecting cylinder in this solution facilitates the operator to rotate the driving ring.

[0018] Optionally, a cross rod is movably inserted into the connecting cylinder. One end of the cross rod inserted into the connecting cylinder is connected to the inner wall of the connecting cylinder by arranging a third spring. The other end of the cross rod is fixedly provided with a control handle. A limiting rod is fixedly provided on the surface of the control handle facing the clamp. The end of the limiting rod away from the control handle is movably inserted into the clamp.

[0019] By adopting the above technical solution, in this solution, when the position adjustment of the driving ring is completed, the control handle is released, and then the control handle is released. At this time, the third spring pulls the control handle to move downward and prompts the limiting rod to be inserted into the clamp, so as to fix the positions of the control handle, the cross rod and the limiting cylinder, thereby reducing the possibility of automatic adjustment of the position of the driving ring.

[0020] Optionally, a first assembly groove corresponding to the first limiting member is provided on the outer side of the clamp. The first assembly groove communicates with the ring groove. The first limiting member is connected to the inner wall of the first assembly groove by arranging a first spring.

[0021] A second assembly groove corresponding to the second limiting member is provided on the inner side of the clamp. The second assembly groove communicates with the ring groove. The second limiting member is connected to the inner wall of the second assembly groove by arranging a second spring.

[0022] By adopting the above technical solution, this solution.

[0023] Optionally, when the depression of the driving ring coincides with the first limiting member, the first spring pulls the first limiting member to be received into the clamp and separated from the connecting plate, so as to facilitate the operator to disassemble the connecting plate; when the depression of the driving ring coincides with the second limiting member, the second spring pulls the second limiting member to be received into the clamp and separated from the nozzle of the wet shotcreting manipulator, so as to facilitate the operator to disassemble the device.

[0024] By adopting the above technical solution, a slot is provided on the side wall of the scraper in this solution. The connecting plate is movably inserted into the slot. The electric push rod facilitates the movement of the scraper, so as to adjust the distance between the scraper and the support. Furthermore, the thickness of the concrete sprayed on the support can be adjusted by the scraper, and the stability of the electric push rod pushing the scraper to move can be increased by the slot.

[0025] In summary, the utility model has at least the following beneficial effects:

[0026] When the operator reversely rotates the driving ring, the first limiting member loses the thrust and resets, separating from the connecting plate, so as to facilitate the operator to disassemble the device into individual components, and further facilitate the operator to store the device;

[0027] When the operator rotates the driving ring, the second limiting member is pushed to move. At this time, the limiting member abuts against the nozzle of the wet shotcreting manipulator, so as to fix the clamp on the nozzle of the wet shotcreting manipulator. Therefore, it is convenient to install the device on the nozzle of the wet shotcreting manipulator. Brief Description of the Drawings

[0035] The following will further describe the present invention in detail with reference to the Figures 1-4 drawings.

[0036] Embodiment 1, referring to Figures 1-4, in this embodiment, in order to solve the problem that after the existing device is used, the operator needs to store the device. However, after the device is assembled, it occupies a large space and is difficult to disassemble, making it inconvenient for the operator to store the device. The utility model discloses a device for adjusting the flatness of shotcrete for support,

[0037] including a connection mechanism 100, which includes two clamps 101. The outer walls of the two clamps 101 are connected by a plurality of connecting plates 102. A concave plate 101a opposite to the connecting plate 102 is fixedly arranged on the outer wall of the clamp 101. The connecting plate 102 is movably inserted into the concave plate 101a. When the connecting plate 102 is inserted into the clamp 101, it is convenient to connect the two clamps 101 together.

[0038] A wet shotcreting manipulator nozzle 103 is movably inserted into the two clamps 101. Through the wet shotcreting manipulator nozzle 103, it is convenient to continuously spray concrete on the support.

[0039] A driving ring 104 is rotatably arranged inside the clamp 101. A first limiting member 105 is movably arranged outside the clamp 101. One end of the first limiting member 105 is inserted into the clamp 101 and abuts against the outer wall of the driving ring 104. The other end of the first limiting member 105 is movably inserted into the connecting plate 102. When the operator rotates the driving ring 104, the first limiting member 105 is pushed to move. At this time, the first limiting member 105 is inserted into the connecting plate 102, thereby fixing the connecting plate 102 on the clamp 101. On the contrary, when the operator rotates the driving ring 104 in the reverse direction, the first limiting member 105 loses the thrust and resets and separates from the connecting plate 102, facilitating the operator to disassemble and store the device.

[0040] Limiting plates 102a are fixedly arranged on both outer walls of the connecting plate 102. The limiting plates 102a are movably inserted into the inner wall of the concave plate 101a. Through the limiting plates 102a, it is convenient to limit the connecting plate 102, so that the connecting plate 102 can only move along the inner wall of the concave plate 101a. And by inserting the first limiting member 105 into the connecting plate 102, it is convenient to fix the connecting plate 102 in the concave plate 101a, thus realizing the assembly of the device.

[0041] A second limiting member 106 is movably arranged inside the clamp 101. One end of the second limiting member 106 is inserted into the clamp 101 and abuts against the inner wall of the driving ring 104. The other end of the second limiting member 106 abuts against the outer wall of the wet shotcreting manipulator nozzle 103. When the operator rotates the driving ring 104, the second limiting member 106 is pushed to move. At this time, the limiting member abuts against the wet shotcreting manipulator nozzle 103, thereby fixing the clamp 101 on the wet shotcreting manipulator nozzle 103.

[0042] The scraping mechanism 200 includes an electric push rod 201 fixedly arranged in the connecting plate 102. The extending end of the electric push rod 201 is fixedly provided with a scraper 202. The scraper 202 is movably sleeved on the connecting plate 102. When the nozzle 103 of the wet shotcreting manipulator continuously sprays concrete, the sprayed concrete is scraped by the scraper 202 at the same time, so as to adjust the flatness of the concrete and make the concrete evenly sprayed and smeared on the support.

[0043] The specific working principle is as follows: First, the two clamps 101 are connected together by four connecting plates 102. Then, the nozzle 103 of the wet shotcreting manipulator is inserted into the clamp 101. Then, the driving ring 104 is rotated and the first limiting member 105 is pushed to move. At this time, the first limiting member 105 is inserted into the connecting plate 102, so as to fix the connecting plate 102 on the clamp 101.

[0044] On the contrary, when the operator reversely rotates the driving ring 104, the first limiting member 105 loses the thrust and resets to separate from the connecting plate 102, which is convenient for the operator to disassemble and store the device.

[0045] Embodiment 2, referring to Figures 2-3 , in this embodiment, in order to solve the problem that the installation of some existing devices is more troublesome, based on the same concept as in Embodiment 1 above, the device for adjusting the flatness of shotcrete for support further includes:

[0046] An annular groove 101b is opened inside the clamp 101. The driving ring 104 is movably arranged in the annular groove 101b. An arc-shaped groove 101c is opened on the top surface of the clamp 101. The arc-shaped groove 101c is communicated with the annular groove 101b. The annular groove 101b is convenient for assembling the driving ring 104, and the rotation of the driving ring 104 is convenient for controlling the movement of the first limiting member 105 and the second limiting member 106.

[0047] A plurality of depressions 104a are opened on the outer wall and the inner wall of the driving ring 104. A connecting cylinder 104b is fixedly arranged on the top surface of the driving ring 104. The connecting cylinder 104b is movably arranged in the arc-shaped groove 101c. The connecting cylinder 104b is convenient for the operator to rotate the driving ring 104. When the depression 104a of the driving ring 104 coincides with the first limiting member 105, the first limiting member 105 is received into the clamp 101 and separated from the connecting plate 102, which is convenient for the operator to disassemble the connecting plate 102. When the first limiting member 105 is separated from the depression 104a of the driving ring 104, the driving ring 104 pushes the first limiting member 105 to move and insert into the connecting plate 102, so as to fix the connecting plate 102 in the concave plate 101a.

[0048] When the recess 104a of the drive ring 104 overlaps with the second limit piece 106, the second limit piece 106 is received in the clamp 101 and separated from the wet spraying robot nozzle 103, so as to facilitate the operator to disassemble the device; when the second limit piece 106 is separated from the recess 104a of the drive ring 104, the drive ring 104 pushes the second limit piece 106 to move and contact with the wet spraying robot nozzle 103, thereby fixing the device on the wet spraying robot nozzle 103.

[0049] A cross rod 104c is movably inserted in the connecting tube 104b, and one end of the cross rod 104c inserted into the connecting tube 104b is connected to the inner wall of the connecting tube 104b by setting a third spring 104d, and a control handle 104e is fixedly set on the other end of the cross rod 104c, and a limiting rod 104f is fixedly set on the side of the control handle 104e facing the clamp 101, and the end of the limiting rod 104f away from the control handle 104e is movably inserted with the clamp 101. When the operator pulls the control to move upward, the control handle 104e drives the limiting member to move and separate from the clamp 101, thereby causing the connecting tube 104b to lose the limit, and then it is convenient for the operator to drive the connecting tube 104b and the driving ring 104 to rotate through the control handle 104e, and as the cross rod 104c reduces the possibility of the control handle 104e rotating, as the cross rod 104c moves upward, the third spring 104d is stretched and deformed;

[0050] When the position adjustment of the drive ring 104 is completed, the control handle 104e is released, and then the control handle 104e is released. At this time, the third spring 104d pulls the control handle 104e downward and prompts the limit rod 104f to be plugged into the clamp 101, thereby fixing the position of the control handle 104e, the cross rod 104c and the limit cylinder, thereby reducing the possibility of automatic adjustment of the position of the drive ring 104.

[0051] The outer side of the clamp 101 is provided with a first assembly groove 101d corresponding to the first stopper 105, and the first assembly groove 101d is communicated with the annular groove 101b. The first stopper 105 is connected to the inner wall of the first assembly groove 101d by setting a first spring 105a. The first assembly groove 101d is convenient for assembling the first stopper 105. When the recess 104a of the drive ring 104 coincides with the first stopper 105, the first stopper 105 is pulled by the first spring 105a to be accommodated in the clamp 101 and separated from the connecting plate 102, so that the operator can disassemble the connecting plate 102 conveniently. When the first stopper 105 is separated from the recess 104a of the drive ring 104, the drive ring 104 pushes the first stopper 105 to move and plug with the connecting plate 102, and causes the first spring 105a to stretch and deform, so as to fix the connecting plate 102 in the concave plate 101a.

[0052] A second assembly groove 101e corresponding to the second limit member 106 is provided on the inner side of the clamp 101, and the second assembly groove 101e is connected to the annular groove 101b. The second limit member 106 is connected to the inner wall of the second assembly groove 101e by setting a second spring 106a. When the recess 104a of the drive ring 104 coincides with the second limit member 106, the second limit member 106 is pulled by the second spring 106a to be received into the clamp 101 and separated from the wet spraying robot nozzle 103, thereby facilitating the operator to disassemble the device. When the second limit member 106 is separated from the recess 104a of the drive ring 104, the drive ring 104 pushes the second limit member 106 to move and contact with the wet spraying robot nozzle 103, and causes the second spring 106a to stretch and deform, thereby fixing the device on the wet spraying robot nozzle 103.

[0053] The specific working principle is: when the operator pulls the control to move upward, the control handle 104e drives the limiter to move and separate from the clamp 101, thereby causing the connecting tube 104b to lose its limit, and then the operator drives the connecting tube 104b and the driving ring 104 to rotate through the control handle 104e;

[0054] When the recess 104a of the driving ring 104 overlaps with the second stopper 106, the second stopper 106 is received in the clamp 101 and separated from the wet spraying robot nozzle 103, so that the operator can disassemble the device easily;

[0055] When the second stopper 106 is separated from the recess 104 a of the driving ring 104 , the driving ring 104 pushes the second stopper 106 to move and contact with the wet spraying robot nozzle 103 , thereby fixing the device on the wet spraying robot nozzle 103 .

[0056] Example 3, refer to Figure 4 Based on the same concept as the first embodiment, the device for adjusting the flatness of the supporting shotcrete further comprises:

[0057] A slot 202a is provided on the side wall of the scraper 202, and the connecting plate 102 is movably inserted in the slot 202a. The scraper 202 can be pushed to move by the electric push rod 201, so as to adjust the distance between the scraper 202 and the support, and then the thickness of the concrete sprayed on the support can be adjusted by the scraper 202, and the stability of the scraper 202 when pushed to move by the electric push rod 201 can be increased by the slot 202a.

[0058] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
