Description

A kind of building tower crane equilibrium arm
Technical field
The utility model relates to a kind of building tower crane equilibrium arm, belongs to technical field of crane equipment.
Background technology
Tower crane is a kind of weight-lifting equipment the most frequently used on building ground, has another name called " tower crane ", with a section spreading (height) (be called for short " standard knot "), is used for hanging the raw MAT'L of the constructions such as working reinforcing bar, wood are stupefied, cement concrete, steel pipe.Tower crane is a kind of requisite equipment on building site.
At present, there is a kind of tower crane, comprise tower crane support, balance chain, hoisting device and balancing device, wherein, tower crane support comprises pinnacle of a pagoda, tower body and operator's compartment, described operator's compartment is placed in the junction of pinnacle of a pagoda and tower body, operator's compartment is fixedly connected with pinnacle of a pagoda and can is arranged on tower body with rotating in a circumferential direction, hoisting device and balancing device are symmetrically placed in the both sides of operator's compartment respectively, balance chain is connected to balancing device, between tower crane support and hoisting device, described hoisting device comprises the crane arm be articulated and connected with tower crane support and the load-bearing device coordinated with crane arm slippage, described balancing device comprises the equilibrium arm be fixedly connected with tower crane support and the equalizing gear be arranged on equilibrium arm, described equalizing gear is made up of counterweight, equilibrium arm is provided with equilibrium arm track, the corresponding equilibrium arm track side of counterweight is installed with pulley, pulley slippage on equilibrium arm track.According to the weight of the weight that crane arm is sling, select the counterweight of equivalent weight, keep the balance of tower crane support itself and tower crane support both sides with this.
But, the building tower crane of this balanced structure, the weight of the weight that crane arm is sling and the weight pole of counterweight are difficult to ensure the balance demonstrate,proved between them, and this just makes crane arm and equilibrium arm easily occur rocking, thus cause the inclination of tower crane support, cause the generation of safety misadventure.
Utility model content
In view of this, the purpose of this utility model is to provide one and can prevents equilibrium arm from rocking, and guarantees a kind of building tower crane equilibrium arm that tower crane balances.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of building tower crane equilibrium arm, it is fixedly connected with tower crane support, be characterised in that, it comprises the armed lever being connected to described tower crane support side, the anchor shaft that runner determined by band is fixedly connected with between this armed lever, two connecting arms be inclined to set are connected with between these anchor shaft two ends and described tower crane support, this connecting arm is determined runner proximal end be provided with retainer in described, determine runner far-end be provided with sliding part in described, be provided with some by the spaced clump weight come of elastic component between this sliding part and retainer, balance rope one end connects described sliding part and walks around describedly determines runner and is connected with tower crane crane arm.
Preferably, above-mentioned a kind of building tower crane equilibrium arm, wherein said elastic component is spring, is sheathedly connected on described connecting arm.
Preferably, above-mentioned a kind of building tower crane equilibrium arm, wherein said clump weight and described connecting arm sliding block joint, it is provided with centre hole, and described connecting arm is free to slide contact through this centre hole.
Preferably, above-mentioned a kind of building tower crane equilibrium arm, wherein said clump weight and described connecting arm Structure deformation, this clump weight comprises two block sizes, the corresponding heavy mail of shape, its upper end is also connected with a roller therebetween, and this roller rolls with described connecting arm and is connected.
Preferably, above-mentioned a kind of building tower crane equilibrium arm, wherein said clump weight lower end is also provided with pin-and-hole, and described clump weight is provided with protection rope each other and is mutually connected in series by clump weight through described pin-and-hole.
Technique effect of the present utility model is mainly reflected in: in the utility model, connecting arm is determined runner proximal end be provided with retainer in described, determine runner far-end be provided with sliding part in described, be provided with some by the spaced clump weight come of elastic component between this sliding part and retainer, when lifting, balance rope drives sliding part slip that clump weight is moved to retainer direction, move along with on a weight, automatic change balance center of gravity, make balance more stable, play weight when transferring simultaneously, the elastic element arranged each other due to clump weight when clump weight moves down can be avoided clump weight decentralization excessive velocities to cause rocking.
Accompanying drawing explanation
Fig. 1: the utility model structural representation;
Fig. 2: the utility model embodiment 2 counterweight block structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is told about further, be easier to make the technical solution of the utility model understand and grasp.
As shown in Figure 1, a kind of building tower crane equilibrium arm, it is fixedly connected with tower crane support 1, comprise the armed lever 2 being connected to described tower crane support 1 side, the anchor shaft 3 that runner 4 determined by band is fixedly connected with between this armed lever 2, two connecting arms be inclined to set 5 are connected with between these anchor shaft 3 two ends and described tower crane support 1, this connecting arm 5 is determined runner 4 proximal end be provided with retainer 6 in described, determine runner 4 far-end be provided with sliding part 7 in described, be provided with some by the spaced clump weight 8 come of elastic component 9 between this sliding part 7 and retainer 6, balance rope one end connects described sliding part 7 and walks around describedly determines runner 4 and is connected with tower crane crane arm.
Wherein, elastic component 9 is spring, is sheathedly connected on described connecting arm 5.
" embodiment 1 "
