Abstract

The utility model discloses a form of arranging of counter weight on swing arm formula tower machine balance arm, counter weight (1) hangs the well rear portion at balance arm (2) to be located between (2) two girders of balance arm, it is spacing fixed with this counter weight (1) through the girder, and above being located this counter weight (1) with installation mechanism that the girder is connected. The beneficial effects are that the counter weight of arranging on the balance arm not only installs, dismantles very conveniently, swift, can satisfy the operation requirement of cement counter weight and cast iron counter weight simultaneously to can effectually shorten the length of balance arm, reduce the quick -witted slewing radius of swing arm tower, make swing arm tower machine satisfy the operation requirement in narrower and small space.

Description

The arrangement form of counterweight on movable arm type tower machine counter-jib

Technical field

The utility model relates to the arrangement form of counterweight on a kind of counter-jib, belongs to movable arm type tower machine technology field.

Background technology

On the counter-jib of existing whip-typed tower crane, counterweight is generally arranged as rear-mounted, as described in Figure 1, be placed on the rearmost end of counter-jib by counterweight, need the installing space outside occupying volume, inwardly place successively again other parts such as tower top, mechanism, and the version of counter-jib is also more single, only can meet the instructions for use of cement counterweight or gray iron counterweight, in the time of design, making, need to consider two kinds of versions, and the demand choice for use different according to client.

But, on existing counter-jib, arrange that the mode of counterweight has following technical disadvantages: 1, version is single, cause the tower machine kind of same performance to increase, be unfavorable for production management and control stock. In the time making, need to consider to drop into different counter-jibs for the pattern of counterweight, need every kind of counter-jib all to keep certain quantity in stock to meet client's needs simultaneously, manufacturing process relatively bothers, and the production cycle is long, is unfavorable for mass production and the management of product.

2, personnel activity space is little, and counterweight is installed, dismounting difficulty is large. In the time carrying out the installation of counterweight, dismounting, personnel can only stand in counter-jib side and operate, and need often to climb to the operation of counterweight top simultaneously, cause counterweight to be installed, dismantle difficulty, and cause operating personnel's security to reduce.

3, the tower machine radius of gyration is large, is unfavorable for the active job in small space. Counterweight is arranged in counter-jib afterbody, causes counter-jib length to increase, when work counter-jib need to take that larger space is turned round, lifting operation.

Summary of the invention

For said structure form, counterweight is arranged the defect or the deficiency that exist, for ensureing that product is installed, convenience and the operability of dismounting, reduce the radius of gyration of counter-jib, the utility model provides the arrangement form of counterweight on a kind of movable arm type tower machine counter-jib, can meet the requirement of installing and using of cement counterweight and gray iron counterweight simultaneously, reduce counter-jib version, facilitate production management, reduce safety stock, can effectively shorten the radius of gyration of movable arm type tower machine, improve applicability and the popularity of Active workings simultaneously.

For achieving the above object, the utility model provides the arrangement form of counterweight on a kind of movable arm type tower machine counter-jib, balance weight hanging is at the postmedian of counter-jib, and between counter-jib two girders, fix spacing this counterweight by girder, and the installing mechanism being connected with girder is positioned at this counterweight top, make the length space of counterweight outside can occupying volume.

Further, described counterweight is cement counterweight or gray iron counterweight, has unified product structure form, saves production cost and management cost.

Further, described counter-jib is the overall structure being welded into, and has improved the reliability of product.

The utility model can meet the installation requirement of cement counterweight and gray iron counterweight simultaneously, counterweight is placed on to the postmedian of counter-jib structure, and spacing with both sides girder, fix, counterweight installs that back upper place can be placed, installing mechanism.

Compared to prior art, this movable arm type tower machine counter-jib arrangement form has following advantage: 1, the tower machine radius of gyration is little, can meet the more user demand of small space. Counterweight is arranged in counter-jib girder inner side by this structure, counterweight top installing mechanism, and counterweight is the length dimension outside occupying volume no longer, can effectively reduce the length of counter-jib, makes the radius of gyration of movable arm type tower machine less, to adapt to the adaption demand of narrow and small place.

2, version is unified, is convenient to manufacture and manage. This structure can meet the requirement of installing and using of cement counterweight and gray iron counterweight simultaneously, and product highly versatile is easy to production management and controls stock.

3, conveniently, product safety is reliable for installation, disassembling section. This counterweight periphery all can be used as operating space, and operating personnel's activity space is large, and operating personnel's security can obtain good guarantee; Counterweight periphery all has girder to make protector simultaneously, avoids counterweight to come off in the course of the work, has improved the security reliability of product.

Brief description of the drawings

Fig. 1 is the arrangement form of counterweight on movable arm type tower machine counter-jib in prior art;

Fig. 2 is for being structural representation of the present utility model;

In figure: 1, counterweight, 2, counter-jib.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 2, the utility model counterweight 1 is suspended on the postmedian of counter-jib 2, and between 2 liang of girders of counter-jib, by girder by spacing this counterweight 1 fixing, this counterweight 1 be applicable to cement counterweight, gray iron counterweight all can, the same form of product. And the installing mechanism being connected with girder can be positioned over this counterweight 1 top, effectively shorten the length of counter-jib 2, the length space of counterweight 1 outside also can occupying volume. And counterweight 1 periphery has girder and afterbody crossbeam, convenient operation personnel activity.

The utility model adopts versatility counter-jib 2 arrangements, counterweight 1 is arranged in to counter-jib 2 inner sides, adopts both sides girder to bear balance weight, counterweight 1 is installed, convenient disassembly, product pattern is unified, and safe and reliable, work-yard strong adaptability, to manufacture management controllability strong.

By applying this technology, the counterweight 1 of arranging on XGTL120 counter-jib 2 not only installs, dismantles very convenient, quick, can meet the instructions for use of cement counterweight and gray iron counterweight simultaneously, and can effectively shorten the length of counter-jib 2, the radius of gyration that reduces movable arm tower crane, makes movable arm tower crane meet the more instructions for use of small space. Meanwhile, the also design of other products is had to important reference value and using value.
