Technical Field

[0001] This utility model relates to the field of support equipment technology, and more specifically, it relates to an earthwork support device. Background Technology

[0002] Earthwork engineering, as a part of construction engineering, mainly includes foundation pit, trench excavation, roadbed excavation, etc. In earthwork engineering, in order to prevent the excavated foundation pit from collapsing, support devices are usually used to reinforce the side walls of the foundation pit.

[0003] Currently, the support system mainly consists of support plates, a base plate, and support columns. When using the support system to reinforce the sidewall of the foundation pit, tools are typically used to lift the support plates, then move them to the sidewall of the foundation pit and fit them against the sidewall. Expansion bolts or rivets are then driven into the support plates to bring them into contact with the sidewall. This process is repeated to fix the support plates to the sidewall in sequence, while also splicing adjacent support plates together. After fixing the support plates to the foundation pit, the base plate is placed at the bottom of the foundation pit and makes contact with the sidewall of the support plates. At the same time, the piles at the bottom of the base plate are driven into the foundation pit to fix the base plate. Finally, the support columns are installed to the support plates and the base plate, thus achieving the effect of reinforcing the sidewall of the foundation pit.

[0004] However, when splicing the support plates on the installed support device, the workers need to screw multiple bolts into the space between two adjacent support plates in order to achieve the effect of splicing the two support plates together. During this process, the workers need to repeatedly perform the operation of screwing the bolts into the support plates, which is quite cumbersome and makes the construction process of the foundation pit quite inconvenient.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an earthwork support device, which solves the problem that when splicing the support plates on the installation support device, workers need to repeatedly screw bolts into the support plates, which is a cumbersome operation and makes the construction of the foundation pit inconvenient.

[0008] The present invention is further configured such that: a lever is fixedly connected to the side wall of the limiting block, and a through groove is provided on the side wall of the sliding groove for the lever to slide, and the lever passes through the through groove to the outside.

[0009] The present invention is further configured such that: a rotating plate is rotatably connected to the side of the mounting plate away from the splicing plate, and a groove is provided on the side wall of the rotating plate for the prying block to enter; when the prying block enters the groove, the limiting block is completely located in the sliding groove and the spring is in a deformed state.

[0010] The present invention is further configured such that when the limiting block and the two side walls of the splicing plate are in contact with each other, the first splicing plate and the side of the slide rail closest to the second splicing plate are in contact with each other.

[0011] The present invention is further configured such that rubber layers are fixedly connected to both sides of the support plate.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] An earthwork support device, such as Figures 1-6 As shown, the structure includes several support plates 1. A first splicing plate 2 is slidably connected to the side wall of each support plate 1, and a second splicing plate 3 is fixedly connected to it. A slide rail 4 is fixedly connected to the side wall of each support plate 1 for the first splicing plate 2 to slide on, preventing the first splicing plate 2 from separating from the support plate 1 during movement and improving the stability of the first splicing plate 2 on the support plate 1. An installation plate 5 is fixedly connected to the side wall of the first splicing plate 2. An installation groove 6 is provided on the side wall of the second splicing plate 3 for the installation plate 5 to pass through. Sliding grooves 7 are provided on the upper and lower sides of the installation plate 5. A limiting block 8 is slidably connected to the sliding groove 7 to fix the installation plate 5 and the installation groove 6 to each other. The bottom of the limiting block 8 and the sliding groove 7 are connected by a spring 9. When the spring 9 is in its natural state, the limiting block 8 and the side wall of the second splicing plate 3 are in contact with each other. Rubber layers 14 are fixedly connected to both sides of each support plate 1, which improves the sealing between the two support plates 1 after they are connected, reducing the amount of sand and gravel from the side wall of the pit falling into the pit through the gap between the two support plates 1.

[0027] When installing the support plates 1 together, the side walls of the two support plates 1 are pressed together. Then, the splicing plate 1 2 is pushed, causing it to move along the slide rail 4 towards the splicing plate 2 3, and the mounting plate 5 is inserted into the mounting groove 6. Then, pressure is applied to the two limiting blocks 8, pressing them into the slide groove 7, while simultaneously causing the spring 9 to deform and compress. Then, the splicing plate 1 2 continues to move in the same direction. At this time, the limiting blocks 8 and the inner wall of the mounting groove 6 are in contact with each other, and the spring 9 is restricted by the mounting groove 6 and cannot deform and recover. When the mounting plate 5 moves to the point where the limiting blocks 8 and the mounting groove 6 separate, the spring 9 loses its restriction and recovers. The deformation is restored and the limiting block 8 moves upward, making contact with the side wall of the second splicing plate 3. At this time, the mounting plate 5 and the mounting groove 6 are restricted by the limiting block 8 and cannot be separated. Consequently, the first splicing plate 2 and the second splicing plate 3 cannot be separated from each other, thus achieving the effect of installing the support plates 1 together. With the setting of the first splicing plate 2 and the second splicing plate 3, when splicing the two support plates 1 together, it is only necessary to insert the mounting plate 5 into the mounting groove 6 to complete the effect of splicing the two support plates 1 together. This facilitates the installation by the staff, reduces the number of operation steps when splicing the support plates 1, and improves work efficiency.

[0028] Furthermore, a lever 10 is fixedly connected to the side wall of the limiting block 8, and a through groove 11 is provided on the side wall of the slide groove 7 for the lever 10 to slide. The lever 10 passes through the through groove 11 to the outside, which facilitates the movement of the limiting block 8 along the slide groove 7 and makes it easier for the work team to operate. A rotating plate 12 is rotatably connected to the side of the mounting plate 5 away from the splicing plate 2. A groove 13 is provided on the side wall of the rotating plate 12 for the lever 10 to enter. When the lever 10 enters the groove 13, the limiting block 8 is completely located in the slide groove 7 and the spring 9 is deformed. In this state, after the limiting block 8 is fully inserted into the slide groove 7, the rotating plate 12 is rotated to move the push block 10 into the groove 13 of the rotating plate 12. At this time, the limiting block 8 is restricted by the push block 10 and the rotating plate 12 and cannot move upward. When the mounting plate 5 passes through the mounting groove 6, the push block 10 and the groove 13 are separated from each other. At this time, the spring 9 can drive the limiting block 8 back to its original position. The setting of the rotating plate 12 makes it easier for the mounting plate 5 to enter the mounting groove 6, and at the same time, it better controls the position of the limiting block 8.

[0029] When the limiting block 8 and the side wall of the second splicing plate 3 come into contact with each other, the side of the first splicing plate 2 and the slide rail 4 closest to the second splicing plate 3 come into contact with each other. This can prevent the first splicing plate 2 from moving after the mounting plate 5 and the mounting groove 6 are fixed together, thereby improving the stability of the first splicing plate 2 on the support plate 1.

[0030] like Figure 1 , Figure 3 , Figure 4 , Figure 6 As shown, both sides of the support plate 1 are provided with connecting grooves 15, and a reinforcing plate 16 is slidably connected in the connecting grooves 15. A connecting block 17 is fixedly connected to the reinforcing plate 16. The support plate 1 is provided with a limiting groove 18 for the connecting block 17 to slide. When the connecting block 17 and the limiting groove 18 are in contact with each other on the side away from the splicing plate 2 3, the reinforcing plate 16 is completely located in the connecting groove 15 close to the splicing plate 1 2. After the two support plates 1 are fixed to each other, the connecting block 17 is moved, which drives the reinforcing plate 16 to move between the two support plates 1. The setting of the reinforcing plate 16 can further improve the fixing effect between the two support plates 1. When it is necessary to disassemble the support plates 1, it is only necessary to move the connecting block 17 to the side of the limiting groove 18 away from the splicing plate 2 3, so that the reinforcing plate 16 is completely located in the connecting groove 15 close to the splicing plate 1 2, which facilitates the subsequent disassembly of the support plate 1.

[0031] The working process of this utility model is as follows:

[0032] When installing the support plates 1 together, the side walls of the two support plates 1 are pressed together. Then, the splicing plate 1 2 is pushed, causing it to move along the slide rail 4 towards the splicing plate 2 3, and the mounting plate 5 is inserted into the mounting groove 6. Then, pressure is applied to the two limiting blocks 8, pressing them into the slide groove 7, while simultaneously causing the spring 9 to deform and compress. Then, the splicing plate 1 2 continues to move in the same direction. At this time, the limiting blocks 8 and the inner wall of the mounting groove 6 are in contact with each other, and the spring 9 is restricted and cannot deform and return to its original shape. When the mounting plate 5 moves to the point where the limiting blocks 8 and the mounting groove 6 separate, the spring 9 loses its restriction and deforms and returns to its original shape. The original movement causes the limiting block 8 to move upwards and simultaneously come into contact with the side wall of the second splicing plate 3. At this time, the mounting plate 5 and the mounting groove 6 are restricted by the limiting block 8 and cannot be separated. Consequently, the first splicing plate 2 and the second splicing plate 3 cannot be separated from each other, thus achieving the effect of installing the support plates 1 together. With the setting of the first splicing plate 2 and the second splicing plate 3, when splicing the two support plates 1 together, it is only necessary to insert the mounting plate 5 into the mounting groove 6 to achieve the effect of splicing the two support plates 1 together. This facilitates the installation by the staff, reduces the number of operation steps when splicing the support plates 1, and improves work efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
