[0027] In view of the problems mentioned in the above background technology, the embodiment of the utility model provides a lightweight agitator lifting device to solve the above technical problems, and its technical solution is as follows:

[0028] A lightweight agitator lifting device, comprising:

[0029] The square pipe column 310, the rotating support 320 and the crane arm; the material of the square pipe column 310 is a square pipe;

[0030] The rotating support member 320 includes a short square tube 321 and a first limiting ring 322 fixed on the top surface of the short square tube 321;

[0031] The short square tube 321 of the rotating support 320 is inserted into the top of the tube cavity of the square tube column 310 and the first limiting ring 322 is stuck on the top surface of the square tube column 310; after the short square tube 321 is inserted into the tube cavity of the square tube column 310, the short square tube 321 and the tube wall of the square tube column 310 restrict each other, so that the rotating support 320 cannot rotate on the square tube column 310;

[0032] The lifting arm includes a short round tube 331, a second limiting ring 332 fixed on the top surface of the short round tube 331, a seat body 333 fixed on the second limiting ring 332, and a force arm 334 fixed on the seat body 333; a lifting ring 340 is provided on the force arm 334;

[0033] The short round tube 331 of the lifting arm passes through the first limiting ring 322 of the rotating support 320 and is inserted into the tube cavity of the short square tube 321, and the bottom surface of the second limiting ring 332 is lower than the top surface of the first limiting ring 322; because the lifting arm is inserted into the rotating support 320 through the short round tube 331, the lifting arm can be freely rotated horizontally on the rotating support 320 with the help of the short round tube 331.

[0034] The working method of a lightweight agitator lifting device provided by the embodiment of the utility model is as follows:

[0035] 1. When in use, plug the square pipe column 310 into the base on the bank of the sewage pool, insert the pull rope into the lifting ring 340 of the lever arm 334 or hang the hand chain hoist 400, tie the flow pusher, agitator, through-wall pump or water pump to the end of the pull rope or connect it to the lifting chain of the hand chain hoist 400, control the pull rope or hand chain hoist 400 to lift the equipment in the sewage pool, and rotate the lifting arm to move the lifted equipment to the ground;

[0036] 2. When the lifting device needs to be transported, the lifting arm and the rotating support 320 are removed from the square tube column 310, and then the square tube column 310 is pulled out from the base on the shore of the sewage pool, and the entire lifting device is split into multiple structural components for separate transportation, which reduces the transportation space occupied by the lifting device and improves the convenience of transportation.

[0037] In this embodiment, the lever arm 334 and the seat body 333 are arranged in a cross-arrangement state; a plurality of shaft holes 333 a are arranged at intervals on the lever arm 334 , a pin shaft 350 is inserted into one of the shaft holes 333 a , and the ring 340 is hooked on the pin shaft 350 .

[0038] The axial hole 333a on the lever arm 334 can be arranged close to the seat body 333. This arrangement can shorten the distance from the force point of the lever arm 334 to the square tube column 310, further improving the compactness of the structure. At the same time, multiple axial holes 333a are arranged on the lever arm 334, and the position of the axial hole 333a for the pin shaft 350 can also be adjusted as needed.

[0039] In this embodiment, a hand winch 400 is also included, and a hook on the hand winch 400 is hooked on the lifting ring 340; the hand winch 400 is connected to the lifting ring 340, and the equipment is lifted with the help of the hand winch 400, which enables workers to easily lift and move heavier equipment without having to rely on pure manpower.

[0041] The basic pole 200 serves as a fixed base for the lifting device, which facilitates the installation of the lifting device. At the same time, the basic pole 200 can be set in different sewage pools according to needs. In this way, several sewage pools can be lifted with the help of one lifting device, reducing the operation cost.

[0042] In this embodiment, a short plug-in square tube 311 is fixed at the bottom of the square tube column 310. The outer diameter of the short plug-in square tube 311 is smaller than the outer diameter of the square tube column 310 and the outer diameter of the short plug-in square tube 311 is smaller than the inner diameter of the foundation pole 200. The square tube column 310 is plugged into the top of the tube cavity of the foundation pole 200 through the short plug-in square tube 311.

[0043] The provision of the short plug-in square tube 311 can facilitate the insertion of the square tube column 310 on the foundation pole 200 . At the same time, the position where the bottom surface of the square tube column 310 is connected to the short plug-in square tube 311 can be used as a limiting structure to limit the square tube column 310 to the top surface of the foundation pole 200 .

[0044] In this embodiment, the rotating support member 320 is made of nylon. The rotating support member 320 made of nylon is light in weight and has high structural strength.
