It can be understood that the foregoing solution can be used in the scenario of controlling the straightening device and can also be used to solve the installation problem of the straightening device.
[0021] For this specific embodiment, the number of the bidirectional lead screws 102 is multiple. The multiple bidirectional lead screws 102 are respectively rotatably connected to the base 101 and respectively pass through the base 101. The number of the transmission gears 103 is multiple. The multiple transmission gears 103 are respectively fixedly connected to the bidirectional lead screws 102 and are respectively located inside the base 101. The internal gear ring 104 is rotatably connected to the base 101 and meshes with the multiple transmission gears 103. The number of the moving blocks 105 is multiple. The multiple moving blocks 105 are respectively threadedly connected to the bidirectional lead screws 102 and are respectively located inside the base 101. The fixing component and the installation component are respectively connected to the base 101. The base 101 provides a supporting function for the device. When the device is in use, the base 101 is installed in the pipe well. The bidirectional lead screw 102 provides a limiting function for the moving block 105. The transmission gear 103 provides a transmission function for the bidirectional lead screw 102. When the device is in use, by rotating the driving shaft 106, the driving gear 107 is driven to rotate, and at the same time, a corresponding one of the transmission gears 103 is driven to rotate. Through the transmission of the internal gear ring 104, the other transmission gears 103 are driven to rotate synchronously, driving the multiple bidirectional lead screws 102 to rotate synchronously, so that the multiple moving blocks 105 move along the corresponding bidirectional lead screws 102 at the same time. By contacting the moving block 105 with the control seat 109, the purpose of controlling the fixing component is achieved.
[0022] Among them, the driving shaft 106 is rotatably connected to the base 101 and passes through the base 101. The driving gear 107 is fixedly connected to the driving shaft 106 and meshes with one of the transmission gears 103. When the device is in use, by connecting the driving shaft 106 to an external power device, the driving shaft 106 rotates. At this time, the driving gear 107 transmits the power of the driving shaft 106 to the transmission gear 103, achieving the purpose of driving the transmission gear 103.
[0023] Secondly, the number of the spring shafts 108 is multiple. The multiple spring shafts 108 are respectively rotatably connected to the base 101 and are respectively located inside the base 101. The number of the control seats 109 is multiple. The multiple control seats 109 are respectively fixedly connected to the spring shafts 108 and are respectively located outside the spring shafts 108.

A torsion spring is arranged inside the spring shaft 108. When the moving block 105 does not contact the control seat 109, the control seat 109 resets. When the moving block 105 contacts the control seat 109, the control seat 109 is pushed along the spring shaft 108, so that the control seat 109 rotates along the spring shaft 108, and at the same time drives the fixed seat 110 and the centering plate 113 to move. Through the centering plate 113, it is convenient to center and fix the downcomer and facilitate the centering of the downcomer.

[0026] Using the pipe uprighting device for foundation pit dewatering in this embodiment, the base 101 provides a supporting function for the device. When the device is in use, the base 101 is installed in the pipe well. The bidirectional lead screw 102 provides a limiting function for the moving block 105, and the transmission gear 103 provides a driving function for the bidirectional lead screw 102. When the device is in use, by rotating the driving shaft 106, the driving gear 107 is driven to rotate, and at the same time, one corresponding transmission gear 103 is driven to rotate. Through the transmission of the internal gear ring 104, the other transmission gears 103 are driven to rotate synchronously, driving a plurality of bidirectional lead screws 102 to rotate synchronously, so that a plurality of moving blocks 105 move along the corresponding bidirectional lead screws 102 at the same time. By contacting the moving block 105 with the control seat 109, the purpose of controlling the fixing component is achieved, solving the problem that when the pipe uprighting device for foundation pit dewatering is in use, the pull rope and spring are used to control the clamping piece, and the pull rope is prone to aging during long-term use, resulting in poor uprighting effect on the dewatering pipe.
