[0008] To achieve the above objectives, this utility model provides the following technical solution: a combined earthwork excavation pit protection device, comprising: a connecting horizontal plate, a first support rod perpendicular to the outer end of the connecting horizontal plate, and an adjustment assembly connected to the inner side of the first support rod, further comprising:

[0009] The second support rod is connected internally to the first support rod, and a connecting crossbar is vertically fixed to the upper end of the second support rod. A disassembly assembly is connected to the outer end of the first support rod, and a reinforcement assembly is fixed to the lower end of the connecting crossbar.

[0010] As a preferred embodiment of this utility model, the adjustment component includes a second stabilizing rod fixed at equal intervals on the connecting horizontal plate, and a first stabilizing rod is provided inside the second stabilizing rod. The first stabilizing rod has a positioning hole inside. A bearing stabilizing plate is vertically fixed to the top of the first support rod.

[0013] As a preferred embodiment of this utility model, the reinforcing component includes a bearing panel fixed to the bottom of the connecting cross plate, and a supporting connecting rod is connected inside the bearing panel, and a supporting pad is provided at the lower end of the supporting connecting rod.

[0014] As a preferred technical solution of this utility model, the supporting connecting rod is threadedly connected to the bearing panel, and four sets of supporting connecting rods are provided on the outer side of the connecting cross plate.

[0015] As a preferred embodiment of this utility model, the second support rod and the first support rod are connected in a sliding manner.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the combined earthwork excavation pit protection device solves the problems of existing excavation protection devices, which are inconvenient to combine, disassemble and install within the construction area due to the large construction range, and are also inconvenient to adjust the protection height. Furthermore, it is not convenient to provide stable support for the device after it has been moved.

[0017] The positioning holes are evenly spaced inside the first stabilizer rod, allowing the first stabilizer rod to slide inside the second stabilizer rod. When the first stabilizer rod moves, the second support rod slides inside the first support rod as well. After adjusting to a suitable height, the connecting rod is inserted through the groove at the top of the first support rod and rotated, thereby connecting the connecting rod to the appropriate positioning hole. The rotation of the connecting rod adjusts and limits the first and second stabilizer rods, increasing stability after movement.

[0018] A first connecting block is fixedly installed at the right end of the first support rod, and the second connecting block and the first connecting block are installed and fixed together by a threaded rod. When the foundation pit is excavated, it is necessary to expand the protection range. At this time, the first connecting block and the second connecting block at the outer end of the adjacent first support rod can be connected. Then, the threaded rod is rotated so that the threaded rod passes through the interior of the second connecting block and the first connecting block, thereby connecting the adjacent first support rods and facilitating the expansion of the protection range. When the threaded rod is rotated in the opposite direction, the first connecting block is disassembled from the second connecting block, making it easy to disassemble the adjacent first support rods. The operation is convenient.

[0019] By manually pushing the first support rod, the moving wheel is rotated, facilitating easy movement of the device. When moved to a suitable position, the reinforcement assembly includes a bearing panel fixed to the bottom of the connecting horizontal plate. The bearing panel is internally connected to a support connecting rod, and a support pad is provided at the lower end of the support connecting rod. The connecting horizontal plate is supported by the support pad. The support connecting rod is threadedly connected to the bearing panel. By rotating the support connecting rod, the support connecting rod moves inside the bearing panel. When the bearing panel is moved below the lower surface of the moving wheel, and four sets of support connecting rods are provided on the outside of the connecting horizontal plate, the device is supported by moving the bearing panel to the ground.

A second support rod 3 is connected inside the first support rod 2, and a connecting horizontal bar 4 is vertically fixed to the upper end of the second support rod 3. The adjustment assembly includes second stabilizing rods 7 fixed at equal intervals on the connecting horizontal plate 1, and a first stabilizing rod 5 is installed inside the second stabilizing rod 7. A positioning hole 6 is provided inside the first stabilizing rod 5. A load-bearing stabilizing plate 9 is vertically fixed to the top of the first support rod 2, and a connecting rod 8 is threadedly connected to the inside of the second stabilizing rod 7. The second stabilizer 7 is slidably connected to the first stabilizer 5. By sliding the first stabilizer 5 inside the second stabilizer 7, when the first stabilizer 5 moves, the second support rod 3 slides along with it inside the first support rod 2. After adjusting to a suitable height, the connecting rod 8 is inserted through the groove at the top of the first support rod 2 and rotated. The positioning holes 6 are equally spaced inside the first stabilizer 5, thereby rotatably connecting the connecting rod 8 with the appropriate positioning holes 6. The rotation of the connecting rod 8 adjusts and limits the first stabilizer 5 and the second stabilizer 7, increasing stability after movement.

The second connecting block 11 and the first connecting block 10 are fixed together by a threaded rod 12. When excavating a foundation pit, if it is necessary to expand the protection area, the first connecting block 10 and the second connecting block 11 at the outer ends of adjacent first support rods 2 can be connected. Then, rotating the threaded rod 12 allows it to pass through the interior of the second connecting block 11 and the first connecting block 10, thus connecting adjacent first support rods 2 and facilitating the expansion of the protection area. Rotating the nut 13 disengages it from the threaded rod 12. Reversing the rotation of the threaded rod 12 disengages the first connecting block 10 from the second connecting block 11, facilitating the disassembly of adjacent first support rods 2. The operation is convenient. The lower end of the connecting horizontal plate 1 is fixed. The device has a reinforcing assembly, and the lower end of the connecting horizontal plate 1 is equipped with a movable wheel. By manually pushing the first support rod 2, the movable wheel can be rotated, facilitating easy movement of the device. When moved to a suitable position, the reinforcing assembly includes a bearing panel 14 fixed to the bottom end of the connecting horizontal plate 1. The bearing panel 14 is internally connected to a support connecting rod 15, and the lower end of the support connecting rod 15 is equipped with a support pad 16. The support pad 16 supports the connecting horizontal plate 1. The support connecting rod 15 is threadedly connected to the bearing panel 14. By rotating the support connecting rod 15, the support connecting rod 15 moves inside the bearing panel 14. When the bearing panel 14 is moved below the lower surface of the movable wheel, and four sets of support connecting rods 15 are provided on the outer side of the connecting horizontal plate 1, the device is supported by moving the bearing panel 14 to fit against the ground, increasing the stability of the support after movement. This is the usage method of this combined earthwork excavation pit protection device.
