Description

Technical Field

[0001] The present application relates to the field of trench construction, and in particular to a trench support structure. Background Art

[0002] During municipal construction, trenches need to be excavated to facilitate the burying of equipment such as pipelines and cables in the soil. In the existing related technologies, a trolley is used for trench excavation. The trolley used for trench excavation can refer to the patent document with announcement number CN 215290144 U, announcement date 2021.12.24, and name "A self-propelled adjustable support trolley". This utility model patent drives the support plate to move in the horizontal and vertical directions through the horizontal cylinder piston and the vertical cylinder piston, and supports the support plates on both sides through the telescopic top support, so that the support plates on both sides are always tightly fitted to the side walls of the trench, thereby supporting the side walls of the trench.

[0003] Regarding the above-mentioned related technologies, the surface roughness of the side walls on both sides of the groove is generally not the same, and the bottom of the groove is generally difficult to keep straight. When the vertical cylinder piston drives the support plate to move in the vertical direction, the support plates on both sides are prone to being out of sync (out of sync means: the movement speed of one side plate is greater than the movement speed of the other side plate), which makes it difficult for the telescopic top support located between the two side plates to stably support the support plate when the support plate moves in the vertical direction, and the telescopic top support is prone to loosening. Summary of the invention

[0004] In order to ensure that the top support can stably support the support plate when the support plate moves in the vertical direction in the groove, the present application provides a groove support structure.

[0005] A groove support structure provided in this application adopts the following technical solution:

[0006] A groove support structure includes a groove support plate, a support rod body and a buffer component. The groove support plate and the support rod body are each provided with two, the two groove support plates are arranged opposite to each other, one end of the two support rod bodies is respectively installed on the two groove support plates, the buffer component is elastic, and the other ends of the two support rod bodies are installed on the buffer component.

[0007] By adopting the above technical solution, when the groove support plate moves in the vertical direction in the groove, the two support rod bodies respectively adapt to the movement speed of the two groove support plates through elastic buffer parts, so that even if the movements of the two groove support plates are not synchronized, the support rod body can still stably support the groove support plate, and can also release the internal force generated by the deformation and displacement of the support rod body through deformation, thereby reducing the load borne by the support rod body.

[0008] Optionally, the buffer component includes an elastic base block and a plurality of rigid ring bodies, the other ends of the two support rod bodies are installed on the elastic base block, the plurality of rigid ring bodies are installed on the elastic base block, and the plurality of rigid ring bodies are wound around the elastic base block.

[0009] By adopting the above technical solution, the elastic base block provides the necessary elasticity for the buffer, and the rigid ring body limits the deformation amplitude of the elastic base block. Then, when the deformation of the buffer is too large, the two adjacent rigid ring bodies press against each other to limit the support rod body, thereby reducing the adverse stress conditions caused by the inclination of the support rod body.

[0010] Optionally, the distance between two adjacent rigid ring bodies is 1-3 mm.

[0011] By adopting the above technical solution, on the one hand, it is ensured that the elastic base block has sufficient deformation space, and on the other hand, it is also convenient to limit the maximum deformation of the elastic base block through the rigid ring body.

[0012] Optionally, a plurality of base block slots are formed on the outer peripheral surface of the elastic base block, and a plurality of the rigid ring bodies are respectively snap-fitted into the base block slots.

[0013] By adopting the above technical solution, the rigid ring body is engaged with the elastic base block through the base block slot, so as to ensure the connection stability between the rigid ring body and the elastic base block.

[0014] Optionally, the material of the elastic base block is rubber, and the elastic modulus of the elastic base block is 4-7Mpa.

[0015] By adopting the above technical solution, the elastic base block whose material is rubber is more durable and suitable for construction environments with relatively harsh environments.

[0016] Optionally, the support rod body has the ability to extend and retract along its own length direction.

[0017] By adopting the above technical solution, it is easy to adjust the distance between the two groove support plates, so as to adapt to grooves of different widths.

[0018] Optionally, the support rod body includes a first screw, a second screw and an adjusting screw, one end of the first screw is installed on the groove baffle, and the other end of the first screw is threadedly engaged with the adjusting screw, one end of the second screw is installed on the buffer member, and the other end of the second screw is threadedly engaged with the adjusting screw, and when the adjusting screw rotates, the first screw and the second screw move in a direction closer to or away from each other.

[0019] By adopting the above technical solution, the first screw rod and the second screw rod can be moved towards or away from each other by rotating the adjusting screw tube, and the structure is reliable and easy to operate.

[0020] Optionally, the groove support plate is installed with a plurality of support plate bases, and the plurality of support plate bases are distributed along the height direction of the groove support plate, and the support rod body is installed on the support plate base by bolts.

[0021] By adopting the above technical solution, it is convenient to adjust the installation position of the support rod body according to the trench depth, soil parameters and load conditions, thereby ensuring the supporting effect of the trench baffle.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the groove support plate moves in the vertical direction in the groove, the two support rods respectively adapt to the movement speed of the two groove support plates through elastic buffers, so that even if the two groove support plates move asynchronously, the support rods can still stably support the groove support plates, and can also release the internal force generated by the deformation and displacement of the support rods through deformation, thereby reducing the load borne by the support rods;

[0024] 2. The elastic base block provides the necessary elasticity for the buffer, and the rigid ring body limits the deformation range of the elastic base block. When the deformation of the buffer is too large, the two adjacent rigid ring bodies press against each other to limit the support rod body and reduce the adverse force caused by the tilt of the support rod body.
