Abstract

The invention relates to the technical field of special slings and in particular relates to a multi-suspension point eccentric special sling. The multi-suspension point eccentric special sling is characterized by comprising a lifting plate and a counter weight, wherein a first suspension point used for lifting the counter weight is formed in one end of the lifting plate; a second suspension point used for lifting mechanical equipment is formed in the other end of the lifting plate; and a third suspension point used for connecting a hanger of hoisting equipment is formed in the middle of the lifting plate. The sling is designed according to a lever balance principle, and the mechanical equipment positioned in a lifting blind area or a dead angle of a workshop traveler can be easily placed or detached.

Description

The eccentric special hanger of many suspension centres
Technical field
The present invention relates to special hanger technical field, be specifically related to the eccentric special hanger of a kind of many suspension centres.
Background technology
In general, lifting operation does not need special special hanger.But we still often can run into lifting blind area or dead angle, especially in the workshop of large-scale factories and miness during operation.The driving in workshop often cannot directly lift, and adopts other loop wheel machine to stretch not open.
As the large-scale cold bed in metallurgical works, be generally positioned at workshop several continuously across.As installed mechanical equipment below crane girder, or need mechanical equipment below to hang out maintenance, if do not have special suspender, shop traveller is difficult to the task of fulfiling assignment.And there is very large security risk, if suspension hook adopts, oblique pull is askew drags, and can cause steel cable slot disengaging, safety regulation for operations does not allow suspension hook to adopt the askew mode operation of dragging of oblique pull yet, can be easy to like this cause steel cable slot disengaging, also can damage weight-lifting equipment, cause safety misadventure.
Summary of the invention
For above-mentioned technical matters, the object of the present invention is to provide the eccentric special hanger of a kind of many suspension centres, this suspender designs according to lever balance theory, can easily the mechanical equipment lifting being positioned at shop traveller lifting blind area or dead angle be put in place or be disassembled.
For achieving the above object, the technical solution used in the present invention is:
The eccentric special hanger of a kind of many suspension centres, it is characterized in that: it comprises boatswain chair and counterweight, described boatswain chair one end is provided with the first suspension centre for hanging counterweight, and the other end is provided with the second suspension centre for hanging mechanical equipment, and middle part is provided with the 3rd suspension centre for being connected with the hanging of weight-lifting equipment.
Described boatswain chair is the box-structure be welded to each other by steel plate.
Described first suspension centre and the second suspension centre place are equipped with multiple through hole, and multiple through hole is all located on the same line; Be provided with joint steel pipe in each through hole, the two ends of joint steel pipe are equipped with spacing steel plate.
Described 3rd suspension centre place is provided with a pair circular hole, is provided with joint steel pipe in each through hole, and the two ends of joint steel pipe are equipped with spacing steel plate.
Described spacing steel plate is circular or square, and its diameter or circumscribed circle diameter are greater than the diameter of joint steel pipe, and arrange with joint steel pipe concentric.
The invention has the beneficial effects as follows: this suspender designs according to lever balance theory, by eccentric lift-on/lift-off system (balancing with adjustable counter balance), mechanical equipment is transported to the certain distance (being generally no more than 3.5m) in suspension hook horizontal displacement direction, can easily the mechanical equipment lifting being positioned at shop traveller lifting blind area or dead angle is put in place or disassemble.Adopt this suspender not only can speed up the work, alleviate operating personnel's labour intensity, but also can work efficiency be improved, save the duration.This suspender can be gathered materials on the spot, and processes easy, low cost, and safe and convenient to use, keeps in repair also simple.And this hanger structure is simple, easily manufactured, do not need special Fabricating machinery; This suspender volume is little, lightweight, deposits and does not substantially account for place; This suspender can Reusability, easy maintenance.

Detailed description of the invention
In order to understand the present invention better, below in conjunction with embodiment and accompanying drawing, technical scheme of the present invention is described further (shown in Fig. 1-3).
The eccentric special hanger of a kind of many suspension centres, it comprises boatswain chair 1 and counterweight 2, described boatswain chair 1 one end is provided with the first suspension centre 4 for hanging counterweight 2, and the other end is provided with the second suspension centre 5 for hanging mechanical equipment 3, and middle part is provided with the 3rd suspension centre 6 for being connected with the hanging of weight-lifting equipment.
Described boatswain chair 1 is served as reasons (going up inferior all around) box-structure that steel plate is welded to each other.
Described first suspension centre 4 and the second suspension centre 5 place equal (evenly) are provided with multiple through hole, and multiple through hole is all positioned on same (level) straight line; The two ends being provided with joint steel pipe 7 described in joint steel pipe 7(in each through hole all exceed boatswain chair 1, and two ends are symmetrical centered by boatswain chair 1), the two ends of joint steel pipe 7 are equipped with spacing steel plate 8.
Described 3rd suspension centre 6 place is provided with a pair circular hole, and the two ends being provided with joint steel pipe 7 described in joint steel pipe 7(in each through hole all exceed boatswain chair 1, and two ends are symmetrical centered by boatswain chair 1), the two ends of joint steel pipe 7 are equipped with spacing steel plate 8.
Described spacing steel plate 8 is circular or square, and its diameter or circumscribed circle diameter are greater than the diameter of joint steel pipe 7, and arrange with joint steel pipe 7 concentric.
Described joint steel pipe 7 is for being connected with suspension hook with counterweight 2, mechanical equipment 3 by steel cable.
More than illustrate and be only Application Example of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalence change that the present patent application the scope of the claims is done, still belong to protection scope of the present invention.
