At this time, the nylon sleeve on the lifting rope can be wound around the rotating ring in the mounting frame. At this time, the lifting equipment is started to drive the fixing frame to rise, so that the nylon sleeve on the lifting rope is raised accordingly, and then the steel rod is driven to move accordingly, so that the prefabricated pier can be lifted up at one end close to the steel rod. At this time, the lifting device is turned on and the fixing frame is turned up and the nylon sleeve on the lifting rope is turned up and the steel rod is turned up and the prefabricated pier is lifted up. The output end of the lifting device is slowly lifted, so that the end of the prefabricated pier column close to the steel rod is lifted along with it until the prefabricated pier column is completely lifted.

[0021] See also Figure 1-2 , Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 It is an overall front view of the first embodiment of the utility model.

[0022] The utility model discloses a prefabricated bridge pier lifting device, comprising a prefabricated pier 101, a steel rod 102 and a lifting assembly 103, wherein the lifting assembly 103 comprises a mounting frame 104, a rotating ring 105, a limiting plate 106, a supporting rod 107, a nylon sleeve 108, a lifting rope 109, a fixing frame 110, an extension plate 111, an auxiliary frame 112, a base 113 and a stabilizing frame 114; the above-mentioned scheme solves the problem that the existing prefabricated pier lifting and turning devices and device groups are used to lift the prefabricated pier 101, which causes the stress between the nylon sleeve 108 and the steel rod 102 to concentrate, and the prefabricated pier 101 is easily damaged.

[0023] According to this specific implementation, the steel rod 102 is installed on the prefabricated pier 101 to facilitate subsequent transportation.

[0024] The mounting frame 104 is fixedly connected to the steel rod 102 and is located on one side of the steel rod 102. The rotating ring 105 is rotatably connected to the mounting frame 104 and is located on one side of the mounting frame 104. The limiting plate 106 is fixedly connected to the steel rod 102 and is located on a side of the steel rod 102 away from the prefabricated pier 101. The supporting rod 107 is fixedly connected to the prefabricated pier 101 and is fixedly connected to the mounting frame 104 and is fixedly connected to the limiting plate 106 and is located on the mounting frame 104. On both sides of the pier 101, the nylon sleeve 108 is slidably connected to the rotating ring 105 and is located on one side of the rotating ring 105. The lifting rope 109 is fixedly connected to the nylon sleeve 108 and is located on the top of the nylon sleeve 108. The fixing frame 110 is fixedly connected to the lifting rope 109 and is located on one side of the lifting rope 109. When the prefabricated pier 101 is completed and needs to be transported to the bridge construction site, the staff first uses the lifting equipment to move the fixing frame 110 on the hook to the side of the prefabricated pier 101. At this time, The nylon sleeve 108 on the lifting rope 109 can be wound around the rotating ring 105 in the mounting frame 104. At this time, the lifting device is started to drive the fixing frame 110 to rise, so that the nylon sleeve 108 on the lifting rope 109 is raised accordingly, thereby driving the steel rod 102 to move accordingly, and the end of the prefabricated pier column 101 close to the steel rod 102 can be lifted. At this time, the output end of the lifting device is slowly lifted, so that the end of the prefabricated pier column 101 close to the steel rod 102 is lifted accordingly, until the prefabricated pier column 101 is lifted. The column 101 is completely lifted, and when the prefabricated pier column 101 is overturned during the lifting, the rotating ring 105 can rotate on the mounting frame 104, so that the nylon sleeve 108 slides on the rotating ring 105 to avoid accidents caused by the overturning of the prefabricated pier column 101, thereby solving the problem that the existing prefabricated pier column 101 lifting and overturning device and device group turns the prefabricated pier column 101 from a lying position to a vertical position during lifting, which causes stress concentration between the nylon sleeve 108 and the steel rod 102, and easily causes damage to the prefabricated pier column 101.

[0025] Secondly, the extension plate 111 is fixedly connected to the mounting frame 104 and is located on one side of the mounting frame 104, and the auxiliary frame 112 is fixedly connected to the fixing frame 110 and is located on one side of the fixing frame 110. The extension plate 111 can prevent the nylon rope from falling off the rotating ring 105, and the auxiliary frame 112 can improve the strength of the fixing frame 110 to prevent the fixing frame 110 from being damaged during use.

When the prefabricated pier 101 is manufactured and needs to be transported to the bridge construction site, the staff first uses the lifting equipment to move the fixing frame 110 on the hook to the side of the prefabricated pier 101. At this time, the nylon sleeve 108 on the lifting rope 109 can be wrapped around the rotating ring 105 in the mounting frame 104. At this time, the lifting equipment is started to drive the fixing frame 110 to rise, so that the nylon sleeve 108 on the lifting rope 109 is raised accordingly, and then The steel rod 102 is driven to follow the movement, and the end of the prefabricated pier 101 close to the steel rod 102 can be lifted. At this time, the output end of the lifting equipment is slowly lifted, so that the end of the prefabricated pier 101 close to the steel rod 102 is lifted until the prefabricated pier 101 is completely lifted. When the prefabricated pier 101 is overturned during lifting, the rotating ring 105 can rotate on the mounting frame 104, so that the nylon sleeve 108 slides on the rotating ring 105 to avoid accidents caused by the overturning of the prefabricated pier 101, thereby solving the problem that the existing prefabricated pier 101 lifting and overturning device and device group turns the prefabricated pier 101 from a lying position to a vertical position during lifting, which causes stress concentration between the nylon sleeve 108 and the steel rod 102, and easily causes damage to the prefabricated pier 101.
