[0015] (1) The utility model provides two telescopic components. By adjusting the length of the two telescopic components, the angle between the support plate and the horizontal plane can be changed, so that the device can adapt to the support work of the inner wall of the foundation pit of different models. First, the two telescopic components on one side are adjusted to make the support plate contact the inner wall of the foundation pit, and the driving ring is rotated.

The outer wall of one side of the connecting frame 506 is fixedly connected to the support plate 4, and the telescopic component 5 includes a limiting tube 501 fixedly connected to the outer wall of one side of the support rod 1, and a slider 502 is slidably connected inside the limiting tube 501. The slider 502 is coaxially fixed with a screw rod 503, and the screw rod 503 is threadedly sleeved with a driving ring 504, and the driving ring 504 is rotatably connected to the outer wall of one side of the limiting tube 501, and one end of the screw rod 503 is fixedly connected to a mounting sleeve 505, and two mounting sleeves 505 on one side are both rotatably connected to one side of the connecting frame 506.

[0024] First, adjust the two telescopic components 5 on one side so that the support plate 4 contacts the inner wall of the foundation pit, rotate the drive ring 504, and the slider 502 cannot rotate due to the restriction of the limit tube 501. The screw 503 will move outward under the cooperation of the slider 502 and the drive ring 504, and then the position of the connecting frame 506 and the support plate 4 will also change. If the support plate 4 is not in full contact with the foundation pit, it is only necessary to change the extension length of one of the screws 503 and cooperate with the other screw 503 to change the angle between the connecting frame 506 and the support plate 4.

[0025] As shown in Figure 1 and Figure 2 As shown, the two support plates 4 are both installed with an extension component 6, and the extension component 6 includes a slide groove 601 opened at both ends of the support plate 4, and an extension plate 602 is slidably connected inside the two slide grooves 601. The same transmission component is installed on the top of the two extension plates 602. The transmission component includes two extension blocks 603 fixedly connected to the outer walls of the tops of the two extension plates 602. A two-way screw rod 604 is rotatably connected to the top of the support plate 4, and the two extension blocks 603 are respectively threadedly connected to the threads at both ends of the two-way screw rod 604. A knob is rotatably connected to the outer wall of one end of the support plate 4, and the knob is coaxially fixed with the two-way screw rod 604.

[0026] Turning the knob changes the area of ​​the support plate 4, so that the device can adapt to foundation pit support work of various sizes. The knob drives the bidirectional screw 604 to rotate, and the bidirectional screw 604 will drive the two extension blocks 603 away from each other, and then the two extension plates 602 will also be driven away from each other along the slide groove 601, and the area of ​​the support plate 4 will also increase accordingly.

[0027] A fixing seat 2 is fixedly connected to the outer wall of the bottom of the support rod 1. The area of ​​the fixing seat 2 is larger than that of the support rod 1. Fixing holes 3 are opened at the four corners of the fixing seat 2. The fixing seat 2 is restricted to the ground by passing a pin through the fixing hole 3. At this time, the position of the support rod 1 will also be restricted.

[0028] The mounting sleeve 505 is installed at the cross position of the connecting frame 506, which can avoid large local pressure and increase the supporting strength.

[0029] The utility model provides a support device in a foundation pit, and the specific working principle is as follows:

[0030] When the device is working, first move the device to the foundation pit, then use the pin to pass through the fixing hole 3 to limit the fixing seat 2 on the ground, at this time the position of the support rod 1 will also be limited, then turn the knob to change the area of ​​the support plate 4, so that the device can adapt to the foundation pit support work of various sizes, the knob drives the two-way screw rod 604 to rotate, the two-way screw rod 604 will drive the two extension blocks 603 away from each other, and then the two extension plates 602 will also be driven along the slide groove 601 away from each other, the area of ​​the support plate 4 will also increase accordingly, first adjust one side The two telescopic components 5 make the support plate 4 contact the inner wall of the foundation pit and rotate the driving ring 504. The slider 502 cannot rotate due to the restriction of the limiting tube 501. The screw 503 will move outward under the cooperation of the slider 502 and the drive ring 504, and the position of the connecting frame 506 and the support plate 4 will also change. If the support plate 4 is not in full contact with the foundation pit, it is only necessary to change the extension length of one of the screws 503 and cooperate with the other screw 503 to change the angle between the connecting frame 506 and the support plate 4.
