Description

Technical Field

[0001] The present invention relates to the technical field of support structures, and particularly to a roadbed support structure for a cut section. Background Technique

[0002] During the road construction process, it is often necessary to excavate a foundation pit for construction operations. The foundation pit is a temporary project, and its function is to provide a space so that the masonry operation of the foundation can be carried out at the designated position according to the design. The safety of the foundation pit directly affects the reliability of the subsequent construction and the safety of the construction personnel. To ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, it is necessary to set up a support structure for reinforcement in the foundation pit. Foundation pit support is a support, reinforcement and protection measure for the side wall of the foundation pit and the surrounding environment.

[0003] When the existing roadbed support structure for a cut section is in use, since the length of the road foundation pit is relatively long, multiple support devices need to be used for connection and assembly before the road foundation pit can be supported. However, when connecting and assembling multiple support devices, multiple fixing bolts need to be used to fix the connection points. The assembly process is relatively cumbersome and not easy to disassemble. Moreover, for this reason, when the existing roadbed support structure for a cut section is assembled, the support device needs to be moved to the designated location. However, since most of the structure of the support device is made of metal materials, it is heavy and not easy to move, and the movement process of the support device is time-consuming and laborious, and a new technical solution needs to be designed to solve this problem. Summary of the Invention

[0004] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to again Figures 1-5, the present invention provides a subgrade support structure for an excavation section, including a support base 100. At the four corners of the bottom of the support base 100, there are rotatably connected moving wheels 110. Inside the support base 100, there is a support mechanism. The support mechanism includes a rotating rod 120. The rotating rod 120 is rotatably connected to the rear side wall of the support base 100. The front end of the rotating rod 120 penetrates through the support base 100 and extends into the inner cavity of the support base 100. On the front and rear sides of the outer side wall of the rotating rod 120, there are fixedly connected driving gears 121. On the front and rear sides of the bottom of the inner cavity of the support base 100, there are rotatably connected threaded rods 130. The top of the threaded rod 130 is fixedly connected with a driven gear 131. The bottom end of the threaded rod 130 penetrates through the support base 100 and extends into the inside of the support base 100. A first threaded sleeve 140 is screwed on the outer side wall of the threaded rod 130. Between the bottom ends of the first threaded sleeves 140 on the front and rear sides, there is fixedly connected a thorn plate 150.

[0023] Specifically, when it is necessary to adjust the position of the support device to move it to a designated assembly location, by rotating the rotating rod 120, the rotating rod 120 drives the driving gear 121 to drive the driven gear 131 meshed with it to rotate, so that the threaded rod 130 rotates, and the first threaded sleeve 140 installed on the threaded rod 130 rises following the rotation of the threaded sleeve, so that the thorn plate 150 installed between the bottom ends of the first threaded sleeves 140 rises, so that the thorn plate 150 does not contact the ground, and the moving wheels 110 contact the ground, so that the support device can be moved to the assembly location. After the movement is completed, by flipping the rotating rod 120, the thorn plate 150 descends, so that the thorn plate 150 contacts the ground to support the support device, so that the support device can be moved, thus eliminating the need for workers to carry the support device to the assembly location.

[0024] Embodiment 2: Please refer to again Figures 1-5, a support plate 200 is fixedly connected to the top of the support base 100. A connecting seat 210 is fixedly connected to the upper side of the right side wall of the support plate 200. Connecting piles 220 are fixedly connected to the upper and lower sides of the rear side wall of the support plate 200. A combined structure is arranged inside the support plate 200. Limiting grooves 230 are formed in the upper and lower sides inside the support plate 200. A gear driving rod 240 is rotatably connected to the right side wall of the support plate 200. The left end of the gear driving rod 240 penetrates through the support plate 200 and extends into the inner cavity of the support plate 200. The top and bottom of the inner cavity of the support plate 200 are rotatably connected with gear driven screw rods 250. One ends of the upper and lower gear driven screw rods 250 are meshed and connected with the gear driving rod 240. The other ends of the upper and lower gear driven screw rods 250 penetrate through the support plate 200 and extend into the inner cavities of the upper and lower limiting grooves 230. A second thread sleeve 251 is sleeved on the outer side wall of the upper and lower gear driven screw rods 250. One ends of the upper and lower second thread sleeves 251 are fixedly connected with mounting plates 260. Plug pins 261 are fixedly connected to the outer side walls of the upper and lower mounting plates 260. One ends of the upper and lower plug pins 261 penetrate through the upper and lower limiting grooves 230 and extend into the inside of the support plate 200.

[0025] Specifically, when assembling adjacent support devices, by inserting the connecting pile 220 on one side of the support plate 200 into the inside of the support plate 200 on the other side, and then rotating the gear driving rod 240 to drive the gear driven screw rod 250 meshed with it to rotate, the second thread sleeve 251 mounted on the gear driven screw rod 250 moves along with the rotation of the gear driven screw rod 250, and the mounting plate 260 mounted on the second thread sleeve 251 moves synchronously, so that the plug pin 261 mounted on the second thread sleeve 251 is inserted into the connecting pile 220 on the support plate 200 on the other side inside the support plate 200, assembling and connecting the two support plates 200, thus eliminating the need to connect and assemble adjacent support devices with multiple fixing bolts, which is convenient for installation and disassembly.

[0026] Working principle: When it is necessary to adjust the position of the support device to move it to a specified assembly location, by rotating the rotating rod 120, the rotating rod 120 drives the driving gear 121 to drive the driven gear 131 engaged therewith to rotate, so that the threaded rod 130 rotates and the first thread sleeve 140 installed on the threaded rod 130 rises following the rotation of the thread sleeve, so that the thorn plate 150 installed between the bottoms of the first thread sleeves 140 rises, so that the thorn plate 150 does not contact the ground, so that the moving wheels 110 contact the ground, so that the support device can be moved to the assembly location. After the movement is completed, by flipping the rotating rod 120, the thorn plate 150 descends, so that the thorn plate 150 contacts the ground to support the support device, so that the support device can be moved, so that it is not necessary for the staff to carry the support device to the assembly location. When it is necessary to assemble adjacent support devices, by inserting the connecting pile 220 on one side of the support plate 200 into the inside of the support plate 200 on the other side, and then rotating the gear driving rod 240 to drive the gear driven screw 250 engaged therewith to rotate, so that the second thread sleeve 251 installed on the gear driven screw 250 moves following the rotation of the gear driven screw 250, so that the mounting plate 260 installed on the second thread sleeve 251 moves synchronously, so that the tenon 261 installed on the second thread sleeve 251 is inserted into the connecting pile 220 on the support plate 200 on the other side inside the support plate 200, to assemble and connect the two support plates 200, so that it is not necessary to use multiple fixing bolts to connect and assemble adjacent support devices, which is convenient for installation and disassembly.
