[0020] The left and right outer walls of gantry 1 are all fixed with dovetail tracks, the back of C mouth sliding plate 2 is installed with the sliding table of dovetail track sliding cooperation, bilateral chain wheel lifting assembly 3 includes bearing seat 301 fixed at the top of both sides of gantry 1, main transmission shaft 302 rotatably installed between two bearing seats 301 and driven shaft 303 rotatably installed on the inner wall of front and back of gantry 1, and the same end of main transmission shaft 302 and driven shaft 303 is installed with chain wheel lifting structure 304 for driving C mouth sliding plate 2 to lift, when bilateral chain wheel lifting assembly 3 works, the rotary power of step motor 4 is transmitted to main transmission shaft 302, then main transmission shaft 302 and driven shaft 303 are powered by chain wheel lifting structure 304, and then chain wheel lifting structure 304 can drive C mouth sliding plate 2, crossboard 5 and other components to lift, so as to change the height of two-way screw rod tightening module 6, right angle frame 7, circular arc mouth evacuation shell 8 and other components, so that the well lid clamped by two-way screw rod tightening module 6 and circular arc mouth evacuation shell 8 can be far away or close to the well mouth, after lifting to the predetermined height, step motor 4 stops working, and the well lid is accurately placed on the well opening;

[0021] The two ends of crossboard 5 are all fixed with convex plate 501, and the side outer wall close to gantry 1 of convex plate 501 is fixed with two steel columns 502, and the end of steel column 502 away from convex plate 501 is fixedly connected with the side outer wall of C mouth sliding plate 2, and convex plate 501 and steel column 502 enable crossboard 5 to be stably installed on the side inner wall of C mouth sliding plate 2;

[0022] The bidirectional screw rod tightening module 6 comprises a bidirectional screw rod rotatably installed on the outer wall of one side of the horizontal plate 5, and a nut pair installed at the threaded ends of the surface of the bidirectional screw rod. The back of the nut pair is in sliding connection with the outer wall of one side of the horizontal plate 5, and the bottom end of the nut pair is fixedly connected with the top end of the right-angle frame 7. The bidirectional screw rod in the bidirectional screw rod tightening module 6 drives the right-angle frame 7 and the circular-arc-port evacuated shell 8 to slide in the X-axis direction through the nut pair, so as to control the distance between the two circular-arc-port evacuated shells 8.

[0023] The circular-arc-port evacuated shell 8 is internally provided with a trapezoidal concave cavity 801, and a rectangular cutaway portion 802 is arranged on the outer wall of the side of the circular-arc-port evacuated shell 8 close to the gantry 1. The trapezoidal concave cavity 801 and the rectangular cutaway portion 802 enable the manhole cover edge to be stably embedded in the circular-arc-port evacuated shell 8, thereby enhancing the contact area between the circular-arc-port evacuated shell 8 and the manhole cover and ensuring that the manhole cover is uniformly clamped in the whole process rather than relying on single-point contact.

[0024] In use, the gantry 1 is first stably installed at the construction site by the staff, and the structure is ensured to be stable and capable of bearing the weight of the manhole cover and the applied force. The height and width of the gantry 1 can be adjusted according to the size of the manhole cover to ensure that the clamping and placement of the manhole cover can be smoothly performed. Then, the manhole cover is inspected to ensure that the surface is smooth, free of defects, and meets the installation standards. Once the manhole cover is ready, the staff can start the clamping process. At this time, the two circular-arc-port evacuated shells 8 need to be lowered to the ground, and the staff manually operates the bidirectional screw rod tightening module 6 to drive the two circular-arc-port evacuated shells 8 to move closer to each other. The circular-arc-port evacuated shells 8 can better fit the edge of the manhole cover, ensuring that the manhole cover will not be damaged during clamping. As the two circular-arc-port evacuated shells 8 move closer to each other, the manhole cover is stably clamped on the circular-arc-port evacuated shells 8, ensuring its stability during lifting. After the manhole cover is clamped, the staff can operate the stepper motor 4 to start the double-sided chain wheel lifting assembly 3 and start the lifting process. The high-precision control of the stepper motor 4 enables the manhole cover to be smoothly lifted at a set speed. During the lifting process, the staff needs to observe the state of the manhole cover at all times to ensure that it does not deviate or shake. Due to the design of the bidirectional screw rod tightening module 6 and the circular-arc-port evacuated shells 8, the manhole cover remains clamped during the lifting process, which can avoid sliding or tilting caused by gravity. Thereafter, the staff moves the device and the manhole cover above the entrance, causing the bidirectional screw rod tightening module 6, the right-angle frame 7, and other components to move downward until the manhole cover is located at the well opening. The staff can release the clamping of the bidirectional screw rod tightening module 6, i.e., the two circular-arc-port evacuated shells 8 move away from each other, and the manhole cover will be stably fixed on the well opening.
