6. A pier top isolation bearing mounting device as claimed in claim 5, characterised in that: First hydraulic cylinders constituting the second support mechanism are respectively arranged on the outer surfaces of the left and right side walls of the U-shaped plate, one end of each first hydraulic cylinder being hingedly connected to the U-shaped plate and the other end being hingedly connected to the second support beam on the same side; an inclination detector is respectively mounted on each second support beam; second hydraulic cylinders constituting the first support mechanism are respectively arranged on the left and right sides of the support plate, both ends of each second hydraulic cylinder being hingedly connected to the first support beam and the support plate.

7. A pier top isolation bearing mounting device as claimed in claim 6, characterised in that: A plurality of horizontal rods are connected between the bottoms of the two opposite first support beams, and the plurality of horizontal rods constitute a ladder structure; no horizontal rod is arranged between the two opposite second support beams, and the two opposite second support beams constitute an installation space.

8. A pier top isolation bearing mounting device as claimed in claim 7, characterised in that: Third hydraulic cylinders are respectively arranged outside the rollers provided at the front and rear sides of the bottoms of the first and second support beams, one end of each third hydraulic cylinder being fixedly connected to the bottom of the first or second support beam, and a foot plate being connected to the other end of each third hydraulic cylinder, the height of the foot plate being higher than the bottom end of the roller in the initial state.

9. A pier top isolation bearing mounting device as claimed in claim 8, characterised in that: A controller is further provided, the controller being electrically connected to the camera, the driving motor of the mesh type pushing chain device, the control circuit of the first, second and third hydraulic cylinders, the inclination detector, and the electric cylinder through wires.

10. A method of using a pier top isolation bearing mounting device as defined in claim 9, comprising: Step 1: After the pier column is formed, guide rails are arranged on both sides of the ground where the pier column is located, the top of each guide rail is provided with a guide groove for the movement of a roller, the guide rails are leveled and then fixed to the ground to ensure that the distance between the guide rails and the central axis of the pier column is consistent; Step 2: one end of the isolation bearing installation device provided at the top of the pier column is pushed into the guide grooves on the left and right sides, and four rollers are respectively pushed into the guide grooves on the left and right sides, as the device moves towards the pier column, the first and second hydraulic cylinders are adjusted to make the foldable guide rail reach a height higher than the top end of the pier column; the base is further leveled by the third hydraulic cylinder; Step 3: the isolation bearing installed between the first and second sliding plates is pulled to one side of the foldable guide rail by the mesh type pushing chain device, and the second guide rail is leveled by retracting the first hydraulic cylinder; Step 4: a worker climbs to the height of the top of the pier column through the ladder structure, sends a signal to the controller through a handheld control panel, moves the isolation bearing along the X and Y axes, aligns the lower plate of the isolation bearing with the installation position on the top of the pier, places the isolation bearing at the installation position by adjusting the first and second hydraulic cylinders, and connects and fixes the lower plate of the isolation bearing to the top of the pier.
