DETAILED DESCRIPTION

[0016] The technical scheme in the utility model will be further described below in combination with the drawings and embodiments.

[0017] The utility model provides a kind of novel equipment jacking device as shown in Figure 1 It comprises concrete foundation pit 1, support 2, limiting frame 3, steel column 4, drive device 5 and top block 6, the mounting cavity 13 is arranged in the foundation pit 1, the middle part of the mounting cavity 13 is provided with the vertical columnar groove 14, the support 2 and limiting frame 3 are all horizontally fixedly installed in the mounting cavity 13, and the support 2 is fixedly connected with the limiting cylinder 15, the inner wall of the limiting cylinder 15 is fixedly connected with the clamping key 17 arranged along radial direction, the steel column 4 is provided with the clamping groove 18 arranged along radial direction and matched with the clamping key 17, the steel column 4 is keyed with the limiting cylinder 15, the rotating disc 16 is arranged between the limiting frame 3, the limiting frame 3 can use two parallel limiting components to slide and limit the rotating disc 16 between limiting components, the rotating disc 16 is transmission connected with drive device 5, the drive device 5 is fixedly installed on the support 2, the center of the steel column 4 and rotating disc 16 is screw connected, and the top block 6 is rotatably installed at the top end of the steel column 4.

[0018] In use, the rotating disc 16 is driven to rotate by the driving device 5 in cooperation with the speed reducer, and due to the limiting effect of the limiting frame 3 on the rotating disc 16 and the limiting effect of the limiting cylinder 15 on the steel column 4, the rotating disc 16 drives the steel column 4 in threaded connection with the rotating disc 16 to vertically ascend, thereby lifting the to-be-detected component resting on the top block 6, and when not in use, the steel column 4 is immersed into the cylindrical groove 14, so that the ground has no protruding part to affect the movement and turning of the detection device, and the use is more convenient. The steel column 4 is driven to ascend and descend by mechanical transmission, which facilitates the installation of the entire device in the installation cavity 13 of the foundation, and at the same time, the jacking device from the height of the foundation is more convenient for ground maintenance personnel to maintain large equipment, which is more reasonable.
