A horizontal adjustment mechanism and a vertical adjustment mechanism are respectively arranged on one side of the support wall 2. Support mechanisms are arranged on both sides of the horizontal adjustment mechanism;

[0029] The horizontal adjustment mechanism realizes the action of reciprocating movement adjustment of the vertical adjustment mechanism in the horizontal direction. The horizontal adjustment mechanism includes a first motor 8. A first support block 7 is fixedly installed on one side of the fixed shell 6 near the top. The first motor 8 is fixedly installed at the bottom of the first support block 7. The output end of the first motor 8 is rotationally connected to a first transmission shaft 9 through a coupling. The first transmission shaft 9 penetrates and extends to the upper part of the first support block 7. A first transmission gear 10 is fixedly installed at one end of the first transmission shaft 9. Second transmission shafts 11 are fixedly installed at the tops of the two fixed shells 6. One end of the second transmission shaft 11 is rotationally connected to a second transmission gear 12 through a ball bearing. The teeth of the first transmission gear 10 mesh with the tooth grooves of the second transmission gear 12. The teeth of the two second transmission gears 12 mesh with the tooth grooves of the transmission rack 4.

[0030] The first motor 8 drives the first transmission gear 10 to rotate. The rotation of the first transmission gear 10 drives the second transmission gear 12 to rotate. The teeth of the second transmission gear 12 mesh with the tooth grooves of the transmission rack 4, enabling the second transmission gear 12 to move on the transmission rack 4, thereby driving the fixed housing 6 to move horizontally, so that the horizontal adjustment mechanism can perform reciprocating motion in the horizontal direction.

[0031] The vertical adjustment mechanism realizes the telescopic adjustment action of the support mechanism in the vertical direction. The vertical adjustment mechanism includes a wheel shaft 13. A third transmission gear 14 is fixedly installed in the middle of the wheel shaft 13. A second support block 15 is fixedly installed on one side of the fixed housing 6 near the middle. A second motor 16 is fixedly installed at the bottom of the second support block 15. The output end of the second motor 16 is rotationally connected to a second transmission shaft 11 through a coupling. The second transmission shaft 11 penetrates and extends to the upper part of the second support block 15. A fourth transmission gear 18 is fixedly installed at the top of the second transmission shaft 11. The teeth of the third transmission gear 14 mesh with the tooth grooves of the fourth transmission gear 18;

[0032] A left-handed thread 19 is provided on the upper arc surface of the upper end of the wheel shaft 13, and a right-handed thread 20 is provided on the lower arc surface of the lower end of the wheel shaft 13. Both ends of the wheel shaft 13 are respectively rotationally connected to the top and bottom of the fixed housing 6 through ball bearings.

[0033] Fixed blocks one 23 are symmetrically and fixedly installed on the outer arc surfaces of the left-handed threaded pipe 21 and the right-handed threaded pipe 22. A movable rod 25 is rotationally connected between every two symmetric fixed blocks one 23 through a pin shaft 24. The intersection of the two movable rods 25 on the same side is rotationally connected through a pin shaft 24.

[0034] The second motor 16 drives the fourth transmission gear 18 to rotate, and the fourth transmission gear 18 drives the third transmission gear 14 to rotate, thereby driving the wheel shaft 13 to rotate;

[0035] The rotation of the wheel shaft 13 can realize the synchronous movement of the left-handed threaded pipe 21 and the right-handed threaded pipe 22 in the vertical direction, and the moving directions of the left-handed threaded pipe 21 and the right-handed threaded pipe 22 are opposite;

[0036] Through the different-direction movements of the left-handed threaded pipe 21 and the right-handed threaded pipe 22 in the vertical direction, the movable rod 25 can be driven to rotate around the pin shaft 24 in the middle of the movable rod 25, realizing the up-and-down telescopic adjustment of the support mechanism.

[0037] The support mechanism realizes the support action on the inner walls of both sides of the deep foundation pit. The support mechanism includes an upper support plate 26 and a lower support plate 27. Second fixing blocks 28 are symmetrically and fixedly installed on the upper part of the upper support plate 26 and the lower part of the lower support plate 27.

The surface of the convex plug rod 29 is slidably inserted into the inner surface of the convex slot 30.

[0038] When the movable rod 25 rotates around the pin shaft 24, it can drive the upper support plate 26 and the lower support plate 27 to move upward. And because the upper support plate 26 and the lower support plate 27 are slidably inserted through the convex plug rod 29 and the convex slot 30, the upper support plate 26 and the lower support plate 27 are integrated to support the side wall of the deep foundation pit.

[0039] The bottom of the base 1 is fixedly connected with moving wheels 31, and the four moving wheels 31 are distributed in a rectangular array at the bottom of the base 1. This enables the device to be conveniently moved through the moving wheels 31, facilitating the operation of workers.

[0040] Working principle: First, move the device to the middle position of the deep foundation pit through the moving wheels 31, and then drive the motor two 16 to drive the wheel shaft 13 to rotate, driving the left-handed threaded pipe 21 and the right-handed threaded pipe 22 to move synchronously, so that the two movable rods 25 rotate around the pin shaft 24 in the middle of the movable rod 25. The rotation of the movable rod 25 drives the up and down movement of the upper support plate 26 and the lower support plate 27, which changes the support area of the upper support plate 26 and the lower support plate 27 to meet the support requirements of the deep foundation pit. When the driving motor one 8 drives the first transmission gear 10 to rotate, it drives the second transmission gear 12 to rotate, so that the second transmission gear 12 moves on the transmission rack 4, driving the fixed shell 6 to move horizontally, so that the upper support plate 26 and the lower support plate 27 support the inner walls of both sides of the deep foundation pit.
