[0031] Further, the fixed base 1 is a plate structure, which can increase the fixing area.

[0032] Further, the fixed base 1 is provided with bolt fixing point 11, which is used for the close connection of the fixed base and the leaf filter machine.

[0033] Further, the number of bolt fixing points 11 is several, and the bolt fixing points 11 are uniformly distributed at the edge position of the fixed base 1, further increasing the stability of the device, ensuring that the whole device will not displace in the running process, providing a stable foundation support for subsequent hoisting operation, and avoiding safety accidents caused by unstable base.

[0034] Further, the rotating support 3 is disc-shaped or polygonal disc-shaped, the lug 4 is located at the edge position of the disc-shaped structure of the rotating support 3, and the opening direction of the lug 4 is upward, facilitating the lifting of the electric hoist.

[0035] Further, the suspension bracket 5 is vertically arranged on the upper surface of the rotating support 4, and at least two suspension brackets 5 are symmetrically distributed, the suspension bracket 5 is a rod-shaped structure, one end of which is connected with the rotating support, and the other end extends outward.

[0036] Further, the safety belt hook 6 is provided with several, and each suspension bracket 5 is provided with at least two and more than two safety hooks 6.

[0037] Further, the area of the fixed base 1 is greater than the cross-sectional area of the bottom of the support column 2, so as to increase the contact area with the installation foundation and improve the carrying capacity;The diameter of the rotating support 3 is greater than the diameter of the top of the support column 2.

[0038] Further, the lug 4 and the rotating support 3 are connected by welding or high-strength bolt connection, the connection position is located at the edge of the rotating support 3 and outside the hanging support, which ensures the force balance of the rotating support during lifting and avoids the shaking of the device.

[0039] Further, the materials of the support column 2, the rotating support 3 and the hanging support 5 are high-strength steel materials, and the connection parts between the support column 2, the rotating support 3 and the hanging support 5 are subjected to reinforced welding treatment.

[0040] Working principle:

[0041] Before the internal structure maintenance or filter cloth replacement operation of the leaf filter is performed, the electric hoist is first connected with the lug 4 of the device. Through the lifting action of the electric hoist, the whole device is lifted and moved to the fixed pressure relief pipeline above the leaf filter. Then, the fixed base 1 of the device is placed stably, and the fixed base 1 is firmly fixed on the pressure relief pipeline by using the bolt through the bolt fixing point 11, so as to ensure that the whole device will not be displaced during the operation.

[0042] Before the operation personnel climb to the top of the leaf filter for operation, the double hooks of the safety belt carried by the operation personnel are hung on the first safety belt hook 61 and the second safety belt hook 62, or the third safety belt hook 63 and the fourth safety belt hook 64.

Since the rotating support 3 can rotate relative to the support column 2, when the operation personnel operate at different positions on the top of the leaf filter, the movement of the body of the personnel will drive the safety belt, and then the rotating support will rotate within a certain range. This rotating process can adjust the position of the operation personnel, so that the personnel can conveniently reach each part of the upper part of the leaf filter for maintenance or filter cloth replacement operation, while ensuring that the safety belt is always in an effective protection state, preventing the personnel from falling from a high place due to accidental loss of balance. During the whole process, the fixed base 1 bears the weight of the operation personnel and various forces generated during the operation, and transmits the force to the installation foundation through the support column 2, so as to ensure the stability and safety of the device.
