Technical Field

[0001] The utility model relates to the technical field of foundation pit supporting equipment, in particular to a foundation pit supporting stabilizing frame. Background Art

[0002] Foundation pit support is a measure of support, reinforcement and protection for the side walls of the foundation pit and the surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. During the construction of the station, the foundation pit support project is expensive and the number of projects started is large. In order to ensure the safety of underground structure construction and the surrounding environment of the foundation pit, it is necessary to install foundation pit support frames inside the foundation pit to protect the inner wall of the foundation pit.

[0003] However, most of the existing foundation pit support frames have a multi-position assembly structure, which makes the support frames insufficiently stable and unable to provide good support and protection for the foundation pit wall, affecting the normal progress of station construction. In addition, the disassembly, assembly and adjustment of the support frames are troublesome and inconvenient. In addition, since the existing support frames are assembled, their use is highly limited and it is difficult to adjust them according to foundation pits of different sizes. Their versatility is poor, so that support frames of corresponding sizes and specifications need to be purchased for support of different foundation pit constructions, which greatly increases the construction cost of the station. Summary of the invention

[0004] In order to solve the above problems, the main purpose of the utility model is to provide a foundation pit support stabilizing frame with a wide range of applications and strong versatility.

The support unit includes a support plate, a first movable guard plate and a first driving mechanism. The first movable guard plate is slidably connected to the support plate in the height direction of the base. The first driving mechanism is connected between the support plate and the first movable guard plate. The first driving mechanism can drive the first movable guard plate to move relative to the support plate in the height direction. The driving unit is connected between the column and the plurality of support units. The driving unit can drive the plurality of support units to spread or retract relative to the column.

[0006] It can be seen from the above that compared with the traditional assembled support frame, the foundation pit support stabilization frame provided by the utility model is more convenient and quick to use; at the same time, the driving unit can drive multiple support units to spread or gather, so that the foundation pit support stabilization frame can be applicable to foundation pits of different sizes within a certain range, and provide stable support for the foundation pit; in addition, the support unit can drive the first movable guard plate to move relative to the support plate through its own first driving mechanism, so that the foundation pit support stabilization frame can be applicable to foundation pits of different depths within a certain range, thereby better expanding the scope of application of the foundation pit support stabilization frame and making the foundation pit support stabilization frame more versatile.

[0007] A preferred solution is that the support unit also includes a second movable guard plate, which is distributed along the height direction with the first movable guard plate, and the second movable guard plate is slidably connected to the support plate in the height direction. The first driving mechanism is also connected between the support plate and the second movable guard plate, and the first driving mechanism can also drive the second movable guard plate to move relative to the support plate in the height direction.

[0008] As can be seen from the above, the addition of the second movable guard plate makes the foundation pit support stabilization frame applicable to foundation pits of greater depth.

[0009] A further solution is that a sliding slot is provided in the support plate, the sliding slot penetrates the support plate in the height direction, and the first movable guard plate and the second movable guard plate can be slidably inserted in the sliding slot; the first driving mechanism includes a driving rod, the driving rod extends in the height direction, and the driving rod is rotatably installed on the support plate around its own axis, the driving rod has a first thread segment and a second thread segment, and the first thread segment and the second thread segment rotate in opposite directions; a through groove is provided on the support plate, the through groove extends in the height direction, the through groove is connected with the sliding slot, the first movable guard plate has a first connecting block, the first connecting block passes through the through groove and is threadedly connected to the first thread segment, and the second movable guard plate has a second connecting block, the second connecting block passes through the through groove and is threadedly connected to the second thread segment.

[0010] As can be seen from the above, the rotational design of the first thread segment and the second thread segment on the driving rod enables the driving rod to drive the first movable guard plate and the second movable guard plate to move toward or away from each other when the driving rod is rotated, so that the first movable guard plate and the second movable guard plate are retracted into the support plate or extended out of the support plate, thereby making the adjustment of the first movable guard plate and the second movable guard plate more convenient and quick.

[0011] A further solution is that the first driving mechanism further includes an operating hand wheel, which is mounted at the bottom of the driving rod; or the first driving mechanism further includes a docking socket, which is mounted at the bottom of the driving rod.

[0012] As can be seen from the above, setting an operating hand wheel allows the staff to easily and reliably control the first movable guard plate and the second movable guard plate to move toward or away from each other through the operating hand wheel; and setting a docking socket allows the staff to drive the first movable guard plate and the second movable guard plate to move toward or away from each other through corresponding tools, and also makes the extension or retraction control of the first movable guard plate and the second movable guard plate more convenient, quick and labor-saving.

[0016] As can be seen from the above, by arranging a supporting sleeve on the column, arranging the telescopic rod into a combination structure of a threaded sleeve and a threaded rod, and arranging a rotating rod and a second driving mechanism, multiple support units can be driven to spread or retract simultaneously through the rotating rod and the second driving mechanism; and setting the telescopic rod as a cylinder allows the driving unit to independently control the movement of a support unit inside, thereby better adapting to the interior of the foundation pit and improving the practicability of the foundation pit support stabilization frame.

[0019] A further solution is that the base includes an upper body, a lower body and a lifting mechanism, the column is installed on the upper body, the lifting mechanism is connected between the upper body and the lower body, and the lifting mechanism can drive the upper body to move relative to the lower body in the height direction; the lifting mechanism is an oil cylinder or a pneumatic cylinder.

[0020] It can be seen from the above that the above design can further expand the applicable depth range of the foundation pit support stabilization frame, and also facilitate the workers to operate on the bottom edge of the foundation pit.

[0021] A further solution is that the foundation pit support stabilization frame also includes more than two support units, and the more than two support units are distributed along the circumference of the base. The support units include an auxiliary support plate, a slider, a bracket, a connecting rod and a first locking piece.
