Abstract
The invention discloses a kind of arrangement form of new-type tower crane counter-jib counterweight, counterweight（1）It is suspended on counter-jib（2）Postmedian, and positioned at counter-jib（2）Between two girders, by girder by the counterweight（1）Spacing fixation, and the installing mechanism being connected with girder is located at the counterweight（1）Top.Beneficial effect be the counterweight arranged on counter-jib not only install, dismantle it is very convenient, quick, cement counterweight and the use requirement of gray iron counterweight can be met simultaneously, and can effectively shorten the length of counter-jib, the radius of gyration of movable arm tower crane is reduced, movable arm tower crane is met the use requirement of more small space.
Description
Technical field
The present invention relates to a kind of arrangement form of new-type tower crane counter-jib counterweight, belong to movable arm type tower crane technical field.
Background technology
On the counter-jib of existing whip-typed tower crane counterweight be typically arranged as it is rear-mounted, as described in Fig. 1, Ji Jiangpei
The rearmost end of counter-jib is placed on again, it is necessary to take extra installing space, and other portions such as tower top, mechanism are inwardly sequentially placed again
Part, and the structure type of counter-jib is also relatively simple, is only capable of meeting cement counterweight or the use requirement of gray iron counterweight, design,
Need to consider two kinds of structure types during making, and used according to the different demand selection of client.
But, arrange that the mode of counterweight has following technical disadvantages on existing counter-jib：1st, structure type is single,
Cause the tower crane kind of same performance to increase, be unfavorable for production management and control stock.The sample for counterweight is needed when making
Formula considers the different counter-jib of input, while need to keep every kind of counter-jib certain quantity in stock to meet client's needs,
Manufacturing process is relatively bothered, and the production cycle is long, is unfavorable for the mass production and management of product.
2nd, personnel activity space is small, big with re-mounting, dismantling difficulty.When carrying out installation, the dismounting of counterweight, personnel can only
Stand and operated in counter-jib side, while need often to climb to operation above counterweight, cause to match somebody with somebody and re-mount, dismantle difficulty, and
Causing the security of operating personnel reduces.
3rd, the tower crane radius of gyration is big, is unfavorable for the active job in small space.Counterweight is arranged in counter-jib afterbody, causes
Balance arm lengths increase, operationally counter-jib need to take bigger space to be turned round, lifting operation.
The content of the invention
For said structure form to the defect or deficiency that exist with rearrangement, the convenience installed, dismantled for guarantee product
Property and operability, reduce the radius of gyration of counter-jib, the present invention provides a kind of arrangement form of new-type tower crane counter-jib counterweight,
The requirement of installing and using of cement counterweight and gray iron counterweight can be met simultaneously, counter-jib structure type is reduced, and facilitate production management, drop
Lower security quantity in stock, while can effectively shorten the radius of gyration of movable arm type tower crane, improves the applicability and extensively of Active workings
Property.
To achieve the above object, the present invention provides a kind of arrangement form of new-type tower crane counter-jib counterweight, and balance weight hanging exists
The postmedian of counter-jib, and between the girder of counter-jib two, by girder by the spacing fixation of the counterweight, and be connected with girder
Installing mechanism is located above the counterweight so that counterweight will not take extra length space.Described counterweight be cement counterweight or
Gray iron counterweight, has unified product structure form, saves production cost and management cost, described counter-jib is the entirety being welded into
Structure, improves the reliability of product.
The present invention can meet the installation requirement of cement counterweight and gray iron counterweight simultaneously, and counterweight is placed on into balance arm configuration
Postmedian, it is and spacing, fixed with both sides girder, counterweight install back upper place can place, installing mechanism.
Compared to prior art, this movable arm type tower crane counter-jib arrangement form has following advantage：1st, tower crane is turned round
Radius is small, can meet the use demand of more small space.Counterweight is arranged on the inside of counter-jib girder by this structure, is pacified above counterweight
Mounting mechanism, counterweight no longer takes extra length dimension, can effectively reduce the length of counter-jib, make the revolution of movable arm type tower crane
Radius is smaller, to adapt to the adaption demand of narrow and small place.
2nd, structure type is unified, is easy to manufacture and manages.This structure can meet cement counterweight and gray iron counterweight simultaneously
Install and use requirement, product highly versatile, it is easy to production management and control stock.
3rd, installation, disassembling section are convenient, and product safety is reliable.The counterweight periphery can be used as operating space, operator
Member's activity space is big, and the security of operating personnel can obtain good guarantee；Counterweight periphery has girder to make protection dress simultaneously
Put, it is to avoid counterweight comes off in the course of the work, improve the security reliability of product.
Brief description of the drawings
Fig. 1 for counterweight on movable arm type tower crane counter-jib in the prior art arrangement form；
Fig. 2 is the structural representation of the present invention；
In figure：1st, counterweight, 2, counter-jib.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Fig. 2 counterweight 1 of the present invention is suspended on the postmedian of counter-jib 2, and between 2 liang of girders of counter-jib, lead to
Girder is crossed by the spacing fixation of counterweight 1, the counterweight 1 is applied to cement counterweight, gray iron counterweight, the same shape of product
Formula.And the installing mechanism being connected with girder can be positioned over the top of counterweight 1, the effective length for shortening counter-jib 2, counterweight
1 will not also take extra length space.And there are girder and afterbody crossbeam in the periphery of counterweight 1, it is easy to operating personnel's activity.
Counterweight 1 is arranged in the inner side of counter-jib 2, using two by the present invention using the arrangement of versatility counter-jib 2
Side girder bears balance weight, and counterweight 1 is installed, convenient disassembly, and product pattern is unified, safe and reliable, work-yard adaptability
By force, management controllability is manufactured strong.
