Technical Field

[0001] The present application relates to the field of housing construction technology, and in particular to a device for maintaining a foundation pit for housing construction. Background Art

[0002] In building construction, foundation pit excavation is required. The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. The support of the foundation pit is to ensure the safety of underground structure construction and the surrounding environment of the foundation pit, and to adopt support, reinforcement and protection measures for the side walls and the surrounding environment.

[0003] The Chinese utility model patent with patent number CN220725119U discloses a foundation pit support device for building construction, including a main board and an adjustable fixed component installed on one side thereof, two groups of protective support plates are arranged inside the main board, and the protective support plates are slidably connected to the inner wall of the main board. A handle is arranged on the main board, and an adjustment mechanism is arranged inside the support. During use, when the protection area of ​​the device needs to be adjusted according to the size of the foundation pit, the operating handle can be rotated to drive the turntable and the rotating rod to rotate, and at the same time drive the meshing first gear and the second gear to rotate, thereby driving the two screws to rotate. Under the action of the thread, the two groups of protective support plates move away from or towards each other along the inner wall of the main board, so that the protection area of ​​the device can be telescopically adjusted.

[0004] In actual use, if there is heavy rain or loose soil, the support will sink, and the sinking will make it difficult to adjust and extend the protective support plate. Utility Model Content

[0005] In order to solve the problem that sinking makes it difficult to adjust and extend the protective support plate, the present application provides a foundation pit maintenance device for house construction.

[0006] The present application provides a housing construction foundation pit maintenance device, which adopts the following technical solution:

[0007] The cam is an angular channel formed between a first and a second camshaft, and the cam is connected to the base plate by a threaded connection. The cam is connected to the base plate by a threaded connection. The cam is connected to the base plate by a threaded connection. The cam is connected to the base plate by a threaded connection.

[0008] A placement groove is provided on the bottom surface of the base plate, and the lifting mechanism includes a lifting plate, a first threaded rod and a turntable. The lifting plate is slidably arranged in the placement groove, and the sliding direction of the lifting plate is vertical. A through hole penetrating the base plate is provided on the base plate, and a first threaded hole for threaded connection of the first threaded rod is provided on the lifting plate. The first threaded rod passes through the through hole and is threadedly connected in the first threaded hole, and the turntable is arranged at an end of the first threaded rod away from the first threaded hole.

[0009] By adopting the above technical solution, one end of the first support rod is hinged on the connecting seat, and the other end is inserted into the insertion groove, which provides support force for the main board and transmits the force to the bottom plate. The second support rod further strengthens the support force of the top surface of the main board, and the second support rod abuts against the limit block. The hinged connection between the main board and the bottom plate facilitates the rotation of the foundation pit maintenance device for housing construction; the lifting plate is threadedly connected to the first threaded rod, and the rotation of the turntable drives the rotation of the first threaded rod, and the lifting plate slides vertically to prop up the bottom plate, and the height of the main board is increased, so that the sliding trajectory of the protective support plate is not easy to sink and be hindered; at the same time, the setting of the bottom plate increases the support area, so that when encountering heavy rain or loose soil, the bottom plate is not easy to sink, so that the protective support plate can be deployed smoothly.

[0010] Optionally, a driving mechanism is provided inside the main board to drive the two groups of protective support plates to slide towards or away from each other, and the driving mechanism includes a dual-axis motor and two groups of second threaded rods. The two groups of second threaded rods are coaxially fixed with the dual-axis motor, and the dual-axis motor drives the two groups of second threaded rods to rotate. The protective support plates are provided with second threaded holes for threaded connection of the second threaded rods.

[0011] By adopting the above technical solution, the dual-axis motor drives the two sets of second threaded rods to rotate through forward and reverse rotation.

[0012] Optionally, a reinforcing rib is provided on a side of the main board facing the first support rod.

[0013] By adopting the above technical solution, when the protective support plate is extended, the main board is hollow, the supporting capacity of the structure is reduced, and the setting of the reinforcing ribs strengthens the protection of the main board after the protective support plate is extended.

[0014] Optionally, the limiting block is a concave block, and the concave surface of the concave block is arranged on a side facing close to the mainboard.

[0015] By adopting the above technical solution, the concave setting of the limiting block allows the second support rod to abut against the connecting seat and is not easy to slide out of the connecting seat, so that the second support rod is stably supported.

[0016] By adopting the above technical solution, several groups of plug rod structures are arranged on the bottom surface of the lifting plate. The plug rod structure includes a plug rod and a fixed seat. The end of the plug rod is arranged on the fixed seat. The fixed seat is fixed to the bottom surface of the lifting plate. A tip is arranged on the end of the plug rod away from the fixed seat.

[0017] By adopting the above technical solution, the rod structure is inserted into the soil through the rods, so that the position of the bottom plate is fixed, and the force applied to the bottom plate is transmitted to the soil through the rod structure, thereby improving the supporting capacity.

[0018] Optionally, a third threaded hole is provided on the lifting plate, a connecting hole for bolt connection is provided on the fixing seat, and the fixing seat is threadedly connected to the bottom of the lifting plate through bolts.

[0020] Optionally, the insertion rod is connected to the fixing seat by providing a clamping block, the diameter of the clamping block is larger than the diameter of the insertion rod, and a countersunk hole for accommodating the clamping block is provided on the fixing seat, and the insertion rod is inserted into the countersunk hole.

[0021] By adopting the above technical solution, the clamping block enables the insertion rod to be inserted into the countersunk hole without falling off, and the setting of the countersunk hole enables the clamping block to be clamped into the countersunk hole without protruding from the surface of the insertion rod structure.

[0022] Optionally, a handle is provided on an eccentric side of the turntable, and the handle is fixed on the turntable.

[0023] By adopting the above technical solution, the setting of the handle facilitates the rotation of the turntable.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The setting of the lifting mechanism allows personnel to manually rotate the turntable to rotate the second threaded rod, thereby driving the lifting plate to slide vertically downward to prop up the bottom plate. When encountering heavy rain or loose soil, the lifting mechanism can be used to raise the bottom plate to avoid support sinking and prevent the protective support plate from being difficult to adjust and extend.

[0026] 2. The dual-axis motor drives the two sets of second threaded rods to rotate, thereby driving the two sets of protective support plates to extend outward, facilitating the sliding of the protective support plates;

[0027] 3. The setting of reinforcing ribs strengthens the mainboard, making it less likely to break. BRIEF DESCRIPTION OF THE DRAWINGS
