The specific embodiment
Core of the present utility model is to provide a kind of clump weight of tower crane, its clump weight body is directly cut by steel plate and forms, and be the T font that is formed by upper body and lower body, because no longer needing the large scale computer Fabricating machinery, the clump weight body carries out surface treatment, therefore, simplify production technology, reduced productive costs.The clump weight of the tower crane that this specific embodiment is provided below in conjunction with Figure of description is described in further detail, so that those skilled in the art understand better.
See also Fig. 1 and Fig. 2, wherein, Fig. 1 is the counterweight block structure schematic diagram of the described tower crane of the specific embodiment, and Fig. 2 is the lateral plan of clump weight shown in Figure 1.
As shown in Figure 1 and Figure 2, the clump weight of the described tower crane of the specific embodiment comprises clump weight body 10, and clump weight body 10 is provided with some hangers 20 for lifting clump weight body 10.Clump weight body 10 is in T shape, is comprised of upper body 11 and lower body 12, and upper body 11 is positioned at the bottom surface formation carrying surface 13 of lower body 12 both sides.Wherein, clump weight body 10 is formed by the direct blanking of the mode of flame gas cutting by plate iron, and cut surface is carried out simple shaping, and from the course of processing of clump weight body 10 as seen, this processing mode is simple, convenient, fast.When dispatching from the factory due to steel plate itself, the two sides is very smooth, smooth, therefore, does not need mechanical process is carried out on the two sides of clump weight body 10 again, thereby has reduced machining processes, has simplified production technology, has reduced productive costs.
The effect of hanger 20 is for the lifting clump weight, and its quantity and position arrange the principle that should follow convenient lifting and guarantee Hoisting Security.In this specific embodiment, the quantity of hanger 20 is eight, eight hangers 20 are equally divided into four groups, two hangers 20 in every group are arranged side by side, wherein two groups of hangers 20 are fixed on respectively on the end face of upper body 11 of clump weight body 10 symmetrically, other two groups of hangers 20 are fixed on respectively on the bottom surface of lower body 12 of clump weight body 10 symmetrically, this design mainly for be heavy weight clump weight.
Obviously, if the small volume of clump weight, weight is lighter, also can be only on the end face of the upper body 11 of clump weight body 10, a hanger 20 be set between two parties, and two hangers 20 perhaps are set symmetrically.For volume and weight larger clump weight again, also can on the bottom surface of the end face of the upper body 11 of clump weight body 10 and lower body 12, each two hangers 20 be set symmetrically respectively, four hangers 20 are set altogether.
Being respectively arranged with the first slide block 14, the first slide blocks 14 on two carrying surfaces 13 of clump weight body 10 can be round steel, can be also the bar shaped bloom, and when adopting the bar shaped bloom, its bottom surface is the inclined-plane along the thickness direction inclination of clump weight body.The concrete effect of the first slide block 14 will together illustrate in conjunction with whip-typed tower crane below.
Except aforementioned clump weight, the utility model also provides a kind of whip-typed tower crane with a plurality of above-mentioned clump weights, see also Fig. 3 and Fig. 4, Fig. 3 is the structural representation of equilibrium arm in the described whip-typed tower crane of the specific embodiment, and Fig. 4 is the lateral plan of equilibrium arm in whip-typed tower crane shown in Figure 3.As shown in Figure 3, Figure 4, the described whip-typed tower crane of the specific embodiment comprises equilibrium arm 30 and a plurality of clump weights 40 that are arranged on equilibrium arm 30, and a plurality of clump weights 40 are arranged in the end face rear portion of equilibrium arm 30 successively along the fore-and-aft direction of equilibrium arm 30.
Special version be, in order to keep the continuity of technical description, conveniently it will be appreciated by those skilled in the art that in the following description, in Fig. 3, Fig. 4 with Fig. 1, Fig. 2 in identical parts adopted identical label to mark.
Be respectively arranged with the first slide block 14 on two carrying surfaces 13 of clump weight 40, be fixed with second slide block 31 corresponding with each the first slide block 14 on the end face of equilibrium arm 30, the end face of the second slide block 31 is certainly rear to front downward-sloping inclined-plane along the fore-and-aft direction of equilibrium arm 30, and the first slide block 14 is placed on the second slide block 31.Like this, after being placed on clump weight 40 on equilibrium arm 30, clump weight 40 can under the effect of self gravitation along the inclined-plane on the second slide block 31 to front slide, be close on previous clump weight, make a plurality of clump weights form an integral body, prevent from mutually colliding when hoisting crane is worked owing to having the gap between each clump weight, improved the safety of hoisting crane work.
In this programme, what the first slide block 14 adopted is round steel, two coaxial settings of round steel on each clump weight, and welding or rotation are arranged on carrying surface 13.This design, guarantee clump weight can slide voluntarily compress in, simple in structure, make easily, reduced productive costs.
Certainly, the first slide block 14 also can adopt other structures, and for example: the first slide block 14 adopts the bar shaped bloom, and the end face of the bottom surface of bar shaped bloom and the second slide block 31 is suitable.
In addition, also be provided with limiting stopper on the first slide block 14, limiting stopper is resisted against on the side of the second slide block 31, can prevent clump weight 40 left and right play on equilibrium arm 30 by limiting stopper, has further improved the safety of hoisting crane work.
To sum up, the technical scheme that the utility model provides has following advantage:
(1) structure design and production technology are reasonable, and be easy to process.The clump weight body is direct blanking moulding take steel plate as raw MAT'L, has simplified production technology, has facilitated manufacturing, has improved production efficiency.
(2) tooling cost is low.When dispatching from the factory due to steel plate itself, the two sides is very smooth, smooth, therefore, only need to carry out simple shaping to cut surface and get final product, therefore, greatly reduce tooling cost, thereby under the prerequisite that guarantees the clump weight overall appearance, greatly reduce the productive costs of clump weight.
(3) easy for installation, safe.Clump weight can rely on the gravity of self automatically to be adjacent to previous clump weight by the second slide block, and therefore, clump weight is easy for installation, and has improved the safety of hoisting crane work.
The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
