The method for temporarily welding the hanging points not only increases the workload, but also wastes time and labor, and the temporarily welded hanging points have the potential safety hazard of falling off; the method for establishing the hanging point by utilizing the combination of a plurality of binding bands or steel wire ropes has insufficient stability and very limited height which can be increased; the method of setting up the scaffold to establish the lifting point requires a large amount of maintenance space. The composition of the utility model comprises: the lifting cylinder (2) and the supporting cylinder (3) are inserted into the supporting cylinder and are in sliding fit with the supporting cylinder, and a plurality of positioning plates (5) for fixing are fixed on the lower circumferential surface of the supporting cylinder; the side walls of the supporting cylinder and the lifting cylinder are provided with at least two groups of symmetrically arranged positioning holes (6); one group of the positioning holes is internally penetrated with a positioning pin (4). The utility model is used for assisting the lifting of the heavy objects in a narrow space.

Description

Adjustable auxiliary device for hoisting heavy objects in narrow space
Technical Field
The utility model relates to an adjustable auxiliary device for hoisting a heavy object in a narrow space.
Background
In the overhaul process of the power equipment, heavy equipment is often hoisted by using a chain block, and the precondition of using the chain block is that the upper part of the equipment is provided with a proper hoisting point. In the practical overhaul process, the upper space of the hoisting equipment is often narrow, a proper hoisting point cannot be found, and the hoisting equipment is insufficient to hoist out. The conventional method is as follows: (1) and (3) utilizing a plurality of binding bands or steel wire rope combinations to establish hanging points (3) by utilizing the existing condition welding hanging points (2) to set up a hoisting scaffold to establish hanging points. The method is theoretically feasible, however, the process is often complicated in the actual application process, and the field requirement is often difficult to meet.
At present, the method for temporarily welding the hanging points in the existing method not only increases the workload, wastes time and labor, but also can change the internal structure and the load of the steel for providing support for the hanging points due to the welding operation, thereby forming unnecessary potential safety hazards, if the fire-fighting operation is not carried out at will at the fireproof important positions, and the temporarily welded hanging points have the potential safety hazards of falling off; the method for establishing the hanging point by utilizing a plurality of binding bands or steel wire ropes has certain limitation, needs enough space and stable fixed points, often has insufficient stability of the established hanging point and has very limited height; the method for building the scaffold to establish the lifting points occupies a large amount of maintenance space, and the higher the lifting points are, the higher the strength of the scaffold to be built is, so that the lifting and transferring of equipment are prevented, and the safety risk of collapse of the scaffold exists.
Disclosure of Invention
The utility model aims to make up the defects of the prior art and provides an adjustable auxiliary device for hoisting a heavy object in a narrow space.
The above object is achieved by the following technical scheme:
an adjustable small space heavy object lifting auxiliary device comprises a lifting cylinder and a supporting cylinder, wherein the lifting cylinder is inserted into the supporting cylinder and is in sliding fit with the supporting cylinder, and a plurality of positioning plates for fixing are fixed on the circumferential surface of the lower side of the supporting cylinder;
the side walls of the supporting cylinder and the lifting cylinder are provided with at least two groups of symmetrically arranged positioning holes;
wherein one group of positioning holes are internally penetrated with positioning pins.
The adjustable small space heavy object lifting auxiliary device is characterized in that the lifting cylinder is a hollow carbon steel cylinder, and a crisscross plate is welded at the top of the hollow carbon steel cylinder.
The adjustable small space heavy object lifting auxiliary device is characterized in that the supporting cylinder is a hollow carbon steel cylinder.
Advantageous effects
1. The utility model can realize normal use of the hoisting equipment of the chain block in a narrow space. The preparation work before hoisting can be greatly reduced, and the hoisting point of the device can easily meet the actual requirements on site. After the device is put into use, the workload of maintenance personnel is greatly reduced. The device can guarantee to have higher level security and stability.
2. The utility model can adjust the height, thereby adjusting the height of the hanging point and being beneficial to the smooth hanging of equipment.

FIG. 3 is a schematic view of the structure of the present utility model in use;
in the figure: 1. a crisscross plate; 2. a lifting cylinder; 3. a support cylinder; 4. a positioning pin; 5. a positioning plate; 6. positioning holes; 7. equipment to be suspended; 8. chain block; 9. a ceiling fixing frame.
Detailed Description
An adjustable small space heavy object lifting auxiliary device comprises a lifting cylinder 2 and a supporting cylinder 3, wherein the lifting cylinder is inserted into the supporting cylinder and is in sliding fit with the supporting cylinder, and a plurality of positioning plates 5 for fixing are fixed on the circumferential surface of the lower side of the supporting cylinder;
the side walls of the supporting cylinder and the lifting cylinder are provided with at least two groups of symmetrically arranged positioning holes 6;
one group of positioning holes is internally penetrated with a positioning pin 4.
The main body part of the hoisting cylinder wall is a section of carbon steel material and a hollow cylindrical cylinder wall, a pair of crisscross solid carbon steel plates are welded on the upper part of the cylinder wall, and the crisscross part is used for hanging a hook of a chain block.
The main body part of the supporting cylinder wall is a section of carbon steel material with the inner diameter slightly larger than the outer diameter of the lifting cylinder wall and a hollow cylindrical cylinder wall, three pairs of positioning pin holes are symmetrically arranged in the middle of the cylinder wall, and four steel plates are symmetrically arranged at the bottom of the cylinder wall along the horizontal direction so as to ensure the fixation and stability of the whole tool.
When the height is adjusted, the positioning holes of the corresponding heights of the lifting cylinder and the supporting cylinder are aligned, then the positioning pins are inserted, the positioning holes on two sides of the supporting cylinder are inserted into the positioning pins, and the overall height of the auxiliary device is controlled in a mode of symmetrically inserting the positioning pins so as to control the height of the lifting point according to the actual space.
Working principle: when the device is used, referring to fig. 3, the device is fixed through the ceiling fixing frame 9 on the upper portion of the equipment 7 to be lifted, the lifting cylinder faces downwards, the height of the lifting cylinder is adjusted according to the height required to be lifted, a locating pin is inserted to fix the height after the height is adjusted, then the upper hook of the chain block 8 is hung on the cross plate, then the equipment is lifted, and through the arrangement of the device, a stable lifting point is formed on the ceiling fixing frame, so that the lifting of the equipment is facilitated.
