[0023] As a further improvement, a mounting groove 15 is provided on the surface of the upper support seat 12, and the upper support arm 11 is embedded in the mounting groove 15 and a pin shaft 16 is provided between the upper support arm 11 and the mounting groove 15. By providing the mounting groove 15 on the surface of the upper support seat 12, it is convenient to make an active connection with the end of the upper support arm 11, so that the upper support arm 11 can push the lifting and lowering anti-collision seat 5 to move up and down.

[0024] As a further improvement, pins 16 are respectively provided at the connections between the joint seat 10 and the upper support arm 11 and the lower support arm 13. The pins 16 are fixedly connected to the joint seat 10 and rotatably connected to the upper support arm 11 and the lower support arm 13. By providing the pins 16 at the connections between the joint seat 10 and the upper support arm 11 and the lower support arm 13, the rotation between the upper support arm 11, the lower support arm 13 and the joint seat 10 is facilitated.

[0025] As a further improvement, the lower support seat 14 has the same structure as the upper support seat 12, and a mounting plate 17 is fixedly connected to the bottom of the lower support seat 14, and the mounting plate 17 is fixedly connected to the bottom of the sink 8.

By fixing the baffle 21 to the top of the fixing seat 4, it is convenient to fix the fixing seat 4 and prevent soil on the ground from entering the fixing seat 4.

[0029] Specifically, the depth of the groove 8 is equal to the height of the lifting anti-collision seat 5, and the internal opening width of the lifting anti-collision seat 5 is greater than the width of the electric cylinder 6. By making the depth of the groove 8 equal to the height of the lifting anti-collision seat 5, it is convenient to embed the lifting anti-collision seat 5 into the fixed seat 4 and keep the top flush with the ground without affecting the passage of other equipment.

[0030] The present invention provides a movable lifting anti-collision seat 5 at the edge of the foundation pit 1, which can not only protect the edge of the foundation pit 1 to prevent other equipment from falling into the foundation pit 1 and damaging the comprehensive experimental testing equipment 2, but also can lower the lifting anti-collision seat 5 to be flush with the ground without affecting the passage of other equipment, thereby greatly enhancing the convenience of use. A linkage rod 7 driven by an electric cylinder 6 is provided between the fixed seat 4 and the lifting anti-collision seat 5 to improve the stability of the connection between the lifting anti-collision seat 5 and the fixed seat 4. The upper support arm 11 and the lower support arm 13 symmetrically distributed on both sides of the joint seat 10 are used to facilitate the linkage rod 9 to push the joint seat 10 to drive the upper support arm 11 and the lower support arm 13 to move synchronously. The structure is simple, the movement is stable, and it is convenient for later maintenance.

[0031] When the present invention is in use, the fixing seat 4 is fixedly installed on the edge of the foundation pit 1, the electric cylinder 6 is controlled to extend and move, and the linkage rods 9 at both ends are pushed outward at the same time, and the joint seat 10 moves outward synchronously with the linkage rod 9, so that the angle between the upper support arm 11 and the lower support arm 13 is reduced, thereby realizing the downward movement of the lifting and anti-collision seat 5. After the lifting and anti-collision seat 5 is fully retracted into the fixing seat 4, the top is flush with the ground and does not affect the passage of other equipment. When machine protection is needed, the electric cylinder 6 is controlled to retract and move, driving the linkage rods 9 at both ends to move inward, and the angle between the upper support arm 11 and the lower support arm 13 is increased, pushing the lifting and anti-collision seat 5 to extend upward from the surface of the fixing seat 4, effectively preventing other equipment from mistakenly entering the foundation pit 1 and causing damage to the comprehensive experimental test equipment 2.
