[0025] As follows, embodiments are further described with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown, as a preferred embodiment 1, a hoisting and lifting device for a circular well comprises a circular track 5 arranged along the top of the circular well and concentric and coaxial with the circular well, a lifting beam 1 is provided at the radial top of the circular track 5, and a rotary running mechanism 4 is provided at both ends of the lifting beam 1. The two ends of the lifting beam 1 form a drivable sliding fit with the circular track 5 through the corresponding rotary running mechanism 4, an electric hoist 3 is provided at the bottom of the lifting beam 1, and a translation mechanism 2 is provided between the top of the electric hoist 3 and the bottom of the lifting beam 1, and the electric hoist 3 forms a drivable sliding fit with the lifting beam 1 through the translation mechanism 2. The lifting beam 1 of the circular well lifting device realizes its circular rotation around the circular track 5 through the rotary running mechanism 4, and in combination with the translation mechanism 2 on the lifting beam 1, the electric hoist 3 can be lifted and hoisted at any point in the circular well.

[0027] The middle axis of the annular track 5 passes through the middle position of the lifting beam 1, and the rotary travel mechanism 4 is symmetrically arranged about the middle position of the lifting beam 1. This ensures stability during hoisting and ensures that the force on the shaft wall is as stable as possible.

[0028] The lifting beam 1 is an I-beam, which is convenient for installing the translation mechanism 2.

[0029] As a preferred embodiment 2, the translation mechanism 2 includes a beam 22 fixedly mounted on the top of the electric hoist 3, the beam 22 is parallel to the lifting beam 1, and horizontal running wheels 21 are provided at both ends of the top of the beam 22. Each horizontal running wheel 21 is suspended on the lower flange plate of the lifting beam 1 and forms a sliding fit with the lower flange plate. A first motor 23 is provided on the beam 22, and each horizontal running wheel 21 forms a transmission fit with the first motor 23.

[0030] Preferably, each horizontal running wheel 21 includes four wheels, which are symmetrically arranged in pairs, with two of them suspended on one side of the lower flange plate of the lifting beam 1 and the other two suspended on the other side of the lower flange plate of the lifting beam 1 to ensure stability.

[0031] A first driving sprocket 24 is coaxially coupled to the output shaft of the first motor 23. A first driven sprocket 25 is provided on each horizontal travel wheel 21. The horizontal travel wheels 21 are linked to the corresponding first driven sprockets 25. A sprocket-chain transmission is formed between the first driving sprocket 24 and the first driven sprocket 25 via a first chain 26. The first motor 23 provides driving force, which drives the horizontal travel wheels 21 to move on the lifting beam 1 through the sprocket-chain transmission, thereby moving the electric hoist 3.

[0032] As a preferred embodiment 3, the slewing walking mechanism 4 includes a mounting beam 43 fixed to the bottom end of the lifting beam 1, and slewing walking wheels 42 are provided at both ends of the mounting beam 43.

A second motor 41 is provided on one side of the mounting beam 43, and the second motor 41 forms a transmission fit with the slewing walking wheels 42 on one side.

[0033] A second driving sprocket 46 is coaxially coupled to the output shaft of the second motor 41. A second driven sprocket 44 is provided on one side of the rotating travel wheel 42. The rotating travel wheel 42 and the corresponding second driven sprocket 44 form a linkage, and a sprocket-chain transmission is formed between the second driving sprocket 46 and the corresponding second driven sprocket 44 via a second chain 45. The second motor 41 provides driving force, which drives the rotating travel wheel 42 on one side to move, thereby causing the entire mounting beam 43 to move along the annular track 5.

[0034] The mounting beam 43 is symmetrical with respect to the lifting beam 1, and the slewing wheels 42 are symmetrical with respect to the middle position of the mounting beam 43, thereby ensuring the stability of movement.

[0035] The walking beam 4-3 is in the shape of "〔". This ensures the stability of movement.

[0036] As a preferred embodiment 4, the output end of the electric hoist 3 is located within the well wall of the circular well to ensure lifting in the well.

[0037] The working principle of this utility model:

[0038] The utility model adopts an I-shaped lifting beam 1 with limit blocks at both ends, and the travel wheel 21 of the translation mechanism 2 is suspended on the lower flange plate of the lifting beam 1. The translation mechanism 2 is driven by the first motor 23, the sprocket and the chain.

[0039] The electric hoist 3 is connected to the crossbeam 22 of the translation mechanism 2. The electric hoist 3 can move horizontally left and right on the lifting beam 1 through the translation mechanism 2.

[0040] The walking system 4 is arranged at both ends of the lifting beam 1, and there are walking wheels symmetrically at both ends of the walking beam 43, so that the walking system can walk around the circular track 5 and realize circular rotation. The track 5 is composed of several sections of railway tracks, each section is bent into an arc shape, assembled into a ring and arranged on the top of the circular pool wall.

[0041] The lifting beam 1 of the circular well lifting device is rotated around the circular track 5 by the rotary walking mechanism 4. In combination with the translation mechanism 2 on the lifting beam 1, the electric hoist 3 can be lifted and hoisted at any point in the circular well.
