[0034] like Figure 1-Figure 4As shown, this embodiment provides a technical solution: a foundation pit support device, including a support plate 1, the top of the support plate 1 is fixedly connected to two support columns 11, and an auxiliary support mechanism 2 is installed between the two support columns 11; the auxiliary support mechanism 2 includes a support mounting plate 24, the top of the support plate 1 is fixedly connected to the support mounting plate 24, the interior of the support mounting plate 24 is rotatably connected to two second rotating plates 23, the tops of the two second rotating plates 23 are rotatably connected to the first rotating plate 22, and one side of the two first rotating plates 22 is rotatably connected to the support top plate 21, the support mounting plate The interior of 24 is equipped with electric telescopic rods 25 that are evenly distributed and used in conjunction with the support top plate 21; auxiliary reinforcement mechanisms 3 are installed on both sides of the support vertical plate 1; the auxiliary reinforcement mechanism 3 includes an auxiliary support base plate 31, and auxiliary support base plates 31 are installed on both sides of the support vertical plate 1. Auxiliary connecting plates 32 are installed under the two auxiliary support base plates 31. The interiors of the two auxiliary connecting plates 32 are slidably connected to the first sliding plate 33, and one side of the first sliding plate 33 is fixedly connected to the corresponding auxiliary support base plate 31. The interiors of the two auxiliary connecting plates 32 are slidably connected to the second sliding plate 34. The second sliding plate 34 is arranged opposite to the first sliding plate 33. The bottoms of the two second sliding plates 34 are fixedly connected to the mounting cross plates 35. The bottoms of the two mounting cross plates 35 are installed with universal wheels 36. One side of the two auxiliary connecting plates 32 is installed with mounting screws 37 extending to the inside of the supporting vertical plate 1. The two mounting screws 37 are threadedly connected to the supporting vertical plate 1. When installing, the mounting screws 37 are screwed together until the auxiliary connecting plate 32 and the supporting vertical plate 1 are reinforced and installed. The operating mode is switched according to the operation requirements of the equipment. When convenient movement is required, the installation is kept The state remains stationary, the first positioning bolt 38 is removed, and the second sliding plate 34 is pulled downward from the inside of the auxiliary connecting plate 32 until it is at a height below the reinforced side plate 13, and is positioned again by the first positioning bolt 38. At this time, the entire equipment is driven to move by the universal wheel 36, which reduces the labor intensity of manual handling equipment. At this time, the entire equipment can be supported by the reinforced side plate 13 and the auxiliary support bottom plate 31, which improves the flexibility of the equipment during use and meets the needs of use in different scenarios. It solves the technical problems in the prior art of single equipment function and inconvenient switching of equipment operation modes during foundation pit support.

[0035] A step further, such as Figure 1-Figure 4As shown: the first rotating plate 22 is fixedly connected to the side of the supporting top plate 21 with the mounting plug plate 5, and the outer side of the mounting plug plate 5 is installed with a limiting shaft 29 that penetrates the supporting top plate 21. A rotating rod is installed between the first rotating plate 22 and the supporting mounting plate 24. The rotating rod is located on one side of the push rod 26. The rotating rod is rotatably connected to the supporting mounting plate 24. The supporting top plate 21 and the first rotating plate 22 are limitedly connected by the limiting shaft 29 and the mounting plug plate 5, which is convenient for normal angle adjustment during use. The first rotating plate 22 and the supporting mounting plate 24 are adjusted by the rotating rod. The mounting plate 24 is connected for limiting, which improves the overall stability of the equipment during operation. The output ends of the electric telescopic rods 25 are fixedly connected with push rods 26, and the top ends of the push rods 26 are installed with buffer pads 27. The tops of the buffer pads 27 are rotatably connected to the bottom of the support top plate 21.

[0036] The above solutions still have the problem of poor stability of the overall support equipment, such as Figure 4 As shown: In this solution, one side of the two auxiliary connecting plates 32 is equipped with a second positioning bolt 39 for use with the first sliding plate 33, and one side of the two auxiliary connecting plates 32 is equipped with a first positioning bolt 38 for use with the second sliding plate 34. The first positioning bolt 38 is located below the corresponding second positioning bolt 39. The second positioning bolt 39 is used to limit the first sliding plate 33 after the height adjustment is completed, and the first positioning bolt 38 is used to limit the second sliding plate 34 after the height adjustment is completed.

[0037] The above solutions still have the problem of being inconvenient to support different scenarios, such as Figure 1-Figure 3 As shown, in this scheme, an inner mounting plate 28 is installed on the top of the support mounting plate 24, and the electric telescopic rod 25 is located on the top of the inner mounting plate 28 and connected to the inner mounting plate 28. A protective partition 4 is fixedly connected to the top of the support mounting plate 24 and on one side of the electric telescopic rod 25. The protective partition 4 is used to isolate and protect the internal equipment of the auxiliary support mechanism 2, and reduce the entry of foreign particles and residues into the interior of the auxiliary support mechanism 2. Limit baffles 12 are installed on the tops of the two support columns 11, and symmetrically distributed reinforcing side plates 13 are installed on the bottoms of the support plates 1. A first mounting hole is provided inside the two limit baffles 12, and a second mounting hole is provided inside the two reinforcing side plates 13. Positioning bolts are installed inside the second mounting holes.

[0038] The above solutions still have the problem of not being able to uniformly manage power equipment, such as Figure 1-Figure 3As shown, in this solution, a control panel is installed on the outside of the supporting column 11, and the electric telescopic rod 25 is electrically connected to the control panel. The control panel is used to control the operation of the electric telescopic rod 25, realizing normal control of the switch. At the same time, the overall equipment uses less power equipment to assist in operation, saving the overall use and installation cost.

[0039] Working principle:

[0040] like Figure 1-4 As shown:

[0041] The rotating rod is located on one side of the push rod 26, and the rotating rod is rotatably connected to the support mounting plate 24. The limiting shaft 29 and the mounting plug plate 5 cooperate to limit the connection between the supporting top plate 21 and the first rotating plate 22, which is convenient for normal angle adjustment during use;

[0042] The first rotating plate 22 and the supporting mounting plate 24 are connected in a limited manner by the rotating rod, thereby improving the overall stability of the equipment during operation;

[0043] The electric telescopic rod 25 is operated to drive the push rod 26 to move upward, and is rotatably connected to the support top plate 21 through the buffer plate 27, so that the support angle of the support top plate 21 can be adjusted, which is suitable for different support scenarios and improves the flexibility of the equipment.

[0044] The first positioning bolt 38 is located below the corresponding second positioning bolt 39. The second positioning bolt 39 limits the first sliding plate 33 after the height adjustment is completed. The first positioning bolt 38 limits the second sliding plate 34 after the height adjustment is completed.

[0045] The protective partition 4 is used to isolate and protect the internal equipment of the auxiliary support mechanism 2, reducing the entry of foreign particles and residues into the auxiliary support mechanism 2;

[0046] A first mounting hole is formed inside the two limit baffles 12, and a second mounting hole is formed inside the two reinforced side plates 13. Positioning bolts are installed inside the second mounting holes.

[0047] The control panel is used to control the operation of the electric telescopic rod 25 and realize normal control of the switch;

[0048] During installation, the mounting screws 37 are screwed together until the auxiliary connecting plate 32 and the supporting vertical plate 1 are reinforced and installed. The operation mode is switched according to the operation requirements of the equipment. When convenient movement is required, the installation state is kept stationary, the first positioning bolts 38 are removed, and the second sliding plate 34 is pulled downward from the inside of the auxiliary connecting plate 32 until it is at a height below the reinforced side plate 13. It is positioned again by the first positioning bolts 38. At this time, the universal wheel 36 is used to drive the entire equipment to move, which reduces the labor intensity of manual handling equipment. When reinforcement support is required, the auxiliary support base plate 31 and the mounting cross plate 35 are flipped together with the mounting screws 37. Remove the second positioning bolt 39 and pull the first sliding plate 33 out from the auxiliary connecting plate 32 until the auxiliary support base plate 31 and the reinforced side plate 13 are on the same horizontal plane, and are positioned by the second positioning bolt 39. At this time, the reinforced side plate 13 and the auxiliary support base plate 31 can be used for overall support, which improves the flexibility of equipment use and meets the needs of use in different scenarios. It solves the technical problems in the prior art that the equipment has a single function and is inconvenient to switch the equipment operation mode when supporting foundation pits. At the same time, the overall equipment uses less power equipment for auxiliary operation, saving the overall use and installation cost, facilitating the angle adjustment of the equipment during support, and improving the overall flexibility of use.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
