Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a supporting device for deep foundation pit construction. Background Art

[0002] As we all know, during the excavation of deep foundation pits, the sinking and deformation of adjacent buildings or structures, roads, pipelines, etc. should be prevented. If necessary, the design unit or construction unit should be consulted to take protective measures and observe the settlement or displacement during construction. Measures should be taken during construction to prevent landslides and avoid serious accidents caused by excavation.

[0003] At present, in order to prevent the collapse of the foundation pit during operation, concrete pouring is mostly used when supporting and reinforcing the deep foundation pit. However, concrete pouring is only suitable for large foundation pits and is inconvenient to use when encountering smaller foundation pits. It is also difficult to quickly adjust the support width according to the actual support needs of the foundation pit width, resulting in poor flexibility in use and great limitations. In view of the above defects, the utility model provides a support device for deep foundation pit construction. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a supporting device for deep foundation pit construction.

[0007] The outer side of the fixing frame is respectively provided with a transmission groove and two movable grooves located below the transmission groove, the same stud is rotatably installed in both movable grooves, and movable seats are respectively connected to the studs located in the two movable grooves through threads, and the outer side of the movable seat is rotatably connected to one end of the oblique anchor rod;

[0008] The top end of the stud rotates and passes through the transmission groove and is fixedly connected to the second bevel gear, the top of the fixed frame is fixedly installed with a top frame, the top of the top frame is fixedly installed with a driving motor, the output end of the driving motor rotates and passes through the bottom of the top frame and is fixedly connected to a worm, a worm wheel is meshed on the worm, and a transmission shaft is fixedly sleeved on the worm wheel, and both ends of the transmission shaft respectively rotate and pass through the transmission groove and are fixedly connected with the first bevel gear, and the first bevel gear is meshed with the second bevel gear.

[0009] Furthermore, a transverse plate is fixedly connected to the inner side of the fixing frame, a rotating seat is fixedly mounted on the transverse plate, and the bottom end of the worm is rotatably mounted on the rotating seat.

[0010] Furthermore, the movable seat is provided with a mounting hole, a threaded pipe is fixedly installed in the mounting hole, and the stud passes through the threaded pipe and is threadably connected to the threaded pipe.

[0011] Furthermore, the studs located in the two movable grooves are respectively provided with external threads, and the thread directions of the two external threads on the studs are arranged in opposite directions.

[0012] Furthermore, a sliding block is arranged on the inner side of the movable seat, a sliding rail is arranged on the inner wall of the movable groove, and the sliding block is slidably mounted on the sliding rail.

[0013] Furthermore, a controller is provided at one end of the top of the top frame, and the controller is electrically controlled and connected to the driving motor.

[0014] By adopting the above structure, the utility model has the following beneficial effects:

[0015] In the utility model, the worm is driven by a driving motor to rotate forward and reversely. When the worm rotates, it meshes with the worm wheel to drive, thereby driving the transmission shaft to rotate. The transmission shaft also meshes with the first bevel gear and the second bevel gear to drive the stud to rotate. Since the thread directions of the two external threads on the stud are arranged in opposite directions, the two movable seats can each be threaded on the two external threads of the stud to move closer to or away from each other through the threaded tube. When the two movable seats move away from or approach each other, the support plates are driven closer to or away from each other through the oblique anchor rod, so that the support position of the support plate can be adjusted according to the width of the deep foundation pit of the building. The structure is simple and easy to adjust and use.

[0016] Finally, the support device for deep foundation pit construction of the building not only prevents the risk of collapse of the deep foundation pit through the support of the support plate, but also can quickly adjust the support position of the support plate according to the actual support needs of the foundation pit width, making the support more flexible and less limited in use, greatly facilitating people's use.
