[0002] In building construction, foundation pit support is a crucial measure to ensure the safety of foundation pit construction and the stability of the surrounding environment. Currently, most commonly used foundation pit support devices are fixed structures, which cannot be flexibly adjusted according to the actual size of the foundation pit. When the size of the foundation pit changes, it is necessary to replace the support device with one of different specifications, which not only increases construction costs but also reduces construction efficiency. Therefore, we propose an adjustable support device for building foundation pit support to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 An adjustable support device for supporting a building foundation pit includes a cylinder 2 for supporting a support plate 1 of the building foundation pit and eight support plates 315. An adjustable support mechanism 3 for supporting the support plate 1 is provided between the cylinder 2 and the eight support plates 315. A lifting ring mechanism 4 is provided at the top of the cylinder 2 and a fixing mechanism is provided at the bottom of the cylinder 2.

[0023] Furthermore, refer to Figures 1-4The adjustable support mechanism 3 includes a drive motor 31 and a reduction gearbox 36 fixedly connected to the top of the cylinder 2, and a lifting screw 34 rotatably connected to the upper and lower inner walls of the cylinder 2. A drive shaft 32 is fixedly connected to the output shaft of the drive motor 31. A drive bevel gear 33 is fixedly connected to one end of the drive shaft 32. A driven bevel gear 35 is fixedly connected to the top of the lifting screw 34. The drive bevel gear 33 and the driven bevel gear 35 mesh with each other. A lifting disc 38 is threaded on the outer side of the lifting screw 34. Four push-pull rods 310 are rotatably arranged on the outer side of the lifting disc 38. A connecting plate 311 is rotatably connected to the outer end of each of the four push-pull rods 310. A vertical plate 313 is fixedly connected to the outer end of the connecting plate 311. Inclined plates 314 are fixedly connected to the upper and lower surfaces of the vertical plate 313. Eight support plates 315 are fixedly connected to one side of the corresponding inclined plate 314. The eight support plates 315 are movably abutting against the inner side of the support plate 1.

[0024] The above scheme is adopted as follows: First, the support plate 1 is attached to the inner walls of the building foundation pit. Then, the drive motor 31 is started. Through the transmission and deceleration of the active bevel gear 33 and the driven bevel gear 35 in the reduction gearbox 36, the output shaft of the drive motor 31 drives the lifting screw 34 to rotate at a reduced speed. Through the limiting guidance of the guide rod 37, the lifting screw 34 drives the lifting plate 38 to move down. The lifting plate 38 drives the four push-pull rods 310 to move down. The four push-pull rods 310 drive the four connecting plates 311 and the vertical plate 313 to move away from each other. The vertical plate 313 drives the inclined plate 314 and the support plate 315 to move outward horizontally in sync. This makes the support plate 315 firmly abut against the inner wall of the corresponding support plate 1, thereby providing stable support and fixation for the support plate 1. Furthermore, by moving the eight support plates 315 closer to or further away from each other, the purpose of adjustment can be achieved, so as to effectively support foundation pits of different sizes and support plates 1, greatly improving the practicality and versatility of the support device.

[0025] Furthermore, bearings are fixedly connected to the bottom of the gearbox 36 and the bottom of the cylinder 2. The lifting screw 34 is fixedly sleeved in the inner ring of the two bearings, which can support the lifting screw 34 and make its rotation more stable.

[0026] Furthermore, four guide rods 37 are fixedly connected to the upper and lower inner walls of the cylinder 2. The lifting plate 38 is slidably sleeved on the outside of the four guide rods 37. Sliding sleeves 312 are fixedly connected to all four sides of the outer side of the cylinder 2. Four connecting plates 311 are slidably sleeved in the corresponding sliding sleeves 312, which can guide the lifting plate 38 and the connecting plate 311, making their movement more stable and smooth.

[0027] Furthermore, ear plates 39 are fixedly connected to the outer perimeter of the lifting plate 38, and four push-pull rods 310 are rotatably connected to the outer perimeter of the corresponding ear plates 39, making it convenient to rotatably connect the four push-pull rods 310 to the outer perimeter of the lifting plate 38.

[0028] Furthermore, refer to Figure 1 and Figure 2 The lifting ring mechanism 4 includes four brackets 41 fixedly connected to the top of the cylinder 2. The same mounting plate 42 is fixedly connected to one end of the four brackets 41 that is close to each other. The top of the mounting plate 42 is fixedly connected to a lifting ring 43. The fixing mechanism includes four support columns 7 fixedly connected to the bottom of the cylinder 2. The bottom end of the support column 7 is fixedly connected to a fixing seat 5. The top of the fixing seat 5 is threaded with two fixing nails 6.

[0029] Using the above scheme: First, attach the support plate 1 to the inner walls of the building foundation pit. By setting up the bracket 41, the mounting plate 42 and the lifting ring 43, the hoisting equipment can be connected to the lifting ring 43, which makes it easier to place the cylinder 2 in the foundation pit. The fixing nail 6 is used to lock the fixing seat 5 and the cylinder 2.

[0030] In this utility model, during use, the support plate 1 is first attached to the inner walls of the building foundation pit. Through the bracket 41, mounting plate 42, and lifting ring 43, the hoisting equipment can be connected to the lifting ring 43, facilitating the placement of the cylinder 2 inside the foundation pit. The fixing nail 6 locks the fixing seat 5 to the cylinder 2. The drive motor 31 is started, and through the transmission and deceleration of the driving bevel gear 33 and driven bevel gear 35 in the reduction gearbox 36, the output shaft of the drive motor 31 drives the lifting screw 34 to rotate at reduced speed. Guided by the guide rod 37, the lifting screw 34 drives the lifting plate 38 to move downwards, raising... The lowering plate 38 causes the four push-pull rods 310 to move downwards. The four push-pull rods 310 cause the four connecting plates 311 and the vertical plate 313 to move away from each other. The vertical plate 313 causes the inclined plate 314 and the support plate 315 to move outwards horizontally in sync, so that the support plate 315 is firmly abutted against the inner wall of the corresponding support plate 1, thereby providing stable support and fixation for the support plate 1. Furthermore, by moving the eight support plates 315 closer to or further apart from each other, the purpose of adjustment can be achieved, so as to effectively support the foundation pits and support plates 1 of different sizes and specifications, greatly improving the practicality and versatility of the support device.
