Abstract
The utility model discloses a kind of derrick crane zoom auxiliary devices, it is characterized by comprising four rack bodies, four rack bodies are symmetricly set on pulley blocks both sides, and the rack body top is flexibly connected with pulley blocks and pulley blocks is supported to keep vertical state.The utility model provides a kind of derrick crane zoom auxiliary device, can effectively solve the problem that derrick crane become multiplying power use during security risk the technical issues of.
Description
Technical field
The utility model is related to derrick crane technical field more particularly to a kind of derrick crane zoom auxiliary devices.
Background technology
Derrick crane answers construction party requirement to need to convert tower crane multiplying power using on the way（4 multiplying powers and 2 multiplying powers
It switches over）, need the upper and lower pulley blocks to be placed into ground when changing multiplying power and then take out attachment device and replaced.But this
Kind mode often will appear steel wire rope and friction even knotting occur with component during zoom, substantially reduce making for steel wire rope
With the service life, or even because upper and lower pulley blocks do not support, it is easy to topple over, is also easy to safety accident occur during zoom.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of derrick crane zoom auxiliary dress
The technical issues of setting, can effectively solve the problem that the security risk during derrick crane becomes the use of multiplying power.
The technical solution adopted in the utility model is：
A kind of derrick crane zoom auxiliary device, it is characterised in that including four rack bodies, four holder sheets
Body is symmetricly set on pulley blocks both sides, and the rack body top is flexibly connected with pulley blocks and pulley blocks is supported to keep vertical shape
State.
Further, the rack body includes mounting portion, diagonal brace portion and perpendicular support part, the mounting portion in it is vertically arranged simultaneously
It being fixedly connected with pulley blocks by bolt, the both ends in the diagonal brace portion connect to form " z " character form structure with mounting portion and perpendicular support part,
Diagonal brace portion is inclined outwardly, and is improved and is acted on the vertical supporting of pulley blocks, while increasing the operating space of operating personnel.
Further, the mounting portion and diagonal brace portion and diagonal brace portion and the angle of perpendicular support part are 120 ~ 160 °.
Further, it is equipped with angle brace in the junction of the diagonal brace portion and perpendicular support part, improves structural stability.
Further, it is linked together using connecting rod positioned at the symmetrically arranged two rack body lower parts in pulley blocks both sides,
Improve the stability of support.
Further, the height of the rack body is 1m, is convenient for operating.
The utility model has the beneficial effects that：
When derrick crane needs to become multiplying power, pulley blocks are vertically lowered into 1 ~ 1.5m or so from the ground by itself,
Rack body is connect with pulley blocks by operating personnel and bolt is fixed.After zoom success, operating personnel can be by holder sheet
Body is removed together, and after dismounting the lifting performance of the i.e. corresponding derrick crane of the weight saving of pulley blocks can be obtained by
It is correspondingly improved.
The utility model kind is formed by distributed rack body and connecting rod assembly, easy to demolition, increases safety coefficient,
Product more hommization, simultaneously effective increases lifting performance.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view structural representation of the utility model.
Specific implementation mode
In order to be more clearly understood the advantages of making the purpose of this utility model and technical solution, below in conjunction with attached drawing and reality
Example, the present invention will be further described in detail.
As shown in figure 1 and 2, a kind of derrick crane zoom auxiliary device, including four rack bodies 1, described in four
Rack body 1 is symmetricly set on 2 both sides of pulley blocks, and 1 top of the rack body is flexibly connected with pulley blocks 2 and supports pulley blocks
2 keep vertical state.
The rack body 1 include mounting portion 11, diagonal brace portion 12 and perpendicular support part 13, the mounting portion 11 in it is vertically arranged simultaneously
It is fixedly connected with pulley blocks 2 by bolt 3, the both ends in the diagonal brace portion 12 connect formation " z " with mounting portion 11 and perpendicular support part 13
Character form structure.
The mounting portion 11 is 120 ~ 160 ° with diagonal brace portion 12 and diagonal brace portion 12 and the angle of perpendicular support part 13.
It is equipped with angle brace 14 in the junction of the diagonal brace portion 12 and perpendicular support part 13.
It is linked together using connecting rod 4 positioned at 2 both sides of pulley blocks, 1 lower part of symmetrically arranged two rack bodies.
The height of the rack body 1 is 1m.
When the utility model is used, pulley blocks 2 are first dropped into 1.5m or so, then by bolt 3 by four holder sheets
Body 1 is fixed on pulley blocks 2, while will be symmetrically installed 2 both sides of pulley blocks two, 1 lower part of support ontology by two connecting rods 4 and be connected
It is connected together, forms stable support construction, be then reduced to the contact of 1 leeway face of rack body to play the height of pulley blocks 2
Supporting role, you can carry out zoom operation.After zoom success, operating personnel can remove rack body 1 together.
