Device for hoisting long-shaft vertical pump and hoisting method thereof

Abstract

The invention belongs to the technical field of long-shaft vertical pump hoisting, and particularly relates to a device for hoisting a long-shaft vertical pump and a hoisting method thereof.The device comprises foundation slabs which are arranged in pairs, distributed on the two opposite sides of a hoisting hole and fixed to the ground; the arc-shaped supporting plates correspond to the foundation bottom plates one to one, one ends of the arc-shaped supporting plates are rotationally connected to the foundation bottom plates, the other ends of the arc-shaped supporting plates are of inwards-concave arc-shaped structures, and the radian of the arc-shaped structures is larger than the corresponding radian of a pump body of the long-shaft vertical pump and smaller than the corresponding radian of a pump body bearing seat of the long-shaft vertical pump; the buffering mechanism is arranged on the foundation bottom plate, located on the outer side of the arc-shaped supporting plate and used for enabling the arc-shaped supporting plate to rotate inwards by not larger than 90 degrees and buffering the arc-shaped supporting plate; and the baffle is arranged on the arc-shaped supporting plate. According to the invention, safe hoisting can be realized, high-altitude falling can be prevented, and safe operation can be realized when a hoisting point is replaced; the stability of the pump body in the hoisting process is improved, and safety is improved.

Description

technical field [0001] The invention belongs to the technical field of hoisting a long-axis vertical pump, and particularly relates to a device for hoisting a long-axis vertical pump and a hoisting method thereof. Background technique [0002] Long shaft vertical pump, widely used in various industrial fields. In the field of underground pool water supply, the long-axis vertical pump is used in the interior of the workshop. Due to space constraints, the vertical pump can only be installed and disassembled using the crane in the workshop as a lifting appliance. The length of the long-axis vertical pump is 8.5 meters, while the maximum lifting height from the hoisting hole of the ground vertical pump to the main crane hook is only 7 meters, and the hoisting height is limited. In the existing technical solutions, such as Figure 5 As shown in the figure, during installation, the vertical pump cannot be hoisted vertically, and the hoisting point needs to be adjusted to the incli...

AI Technical Summary

Problems solved by technology

[0004] 1. The components of the vertical pump are hoisted multiple times, the operation risk is high, and the hoisting time is long;

[0005] 2. When the pump set is placed during hoisting, the pump body is in a tilted state, and the filter at the bottom of the pump is lowered on the concrete of the pool surface, resulting in uneven force on the bottom filter, which eventually leads to damage to the filter of the pump set;

[0006] 3. When the pump set is hoisted for the second time, the operator needs to replace the hoisting point on the ground of the hoisting hole and needs to carry out binding operations, and there is a risk of falling from a high place;

[0007] 4. The pump body has been placed in the sludge for a long time, and a large amount of sludge and oil stains are attached to the pump body. When the pump body is lifted out, it is also accompanied by a large amount of sludge and oil stains, causing great pollution and damage to the work site;

[0008] 5. When the pump set is hoisted or installed, when the pump body penetrates the narrow hoisting hole, the pump body is likely to collide with the edge of the hole, causing damage to the pump body, or the collapse of the concrete at the edge of the hole, causing various equipment accidents and falling accidents from heights
