Abstract
The utility model provides a counterweight device for a crane. The device comprises counterweight blocks, wherein the counterweight blocks are installed inside a supporting frame, sleeve barrels are sleeved at the upper ends of the supporting frame, locking handles are arranged at the lower ends of the sleeve barrel, the upper ends of the sleeve barrels are connected through a connection frame, a hanging lug is fixed on the connection frame, the number of the counterweight blocks can be adjusted flexibly in accordance with specific operation requirements, positions of the sleeve barrels can be adjusted conveniently in accordance with the number of the counterweight blocks, the upper edges of the counterweight blocks at the top end are flush with the connection frame, the stability and the safety of combined counterweight blocks are improved, round-platform-shaped bosses are arranged on the upper end faces of the counterweight blocks, counter holes which correspond to the shape of the bosses are arranged on the lower end faces of the counterweight blocks, the two adjacent counterweight blocks inside the supporting frame are connected with the counter holes through the bosses, axial and radial positioning of the counterweight blocks can be conducted through the connection mode, and the stability and the safety of the counterweight blocks are improved.
Description
Technical field
The utility model relates to a kind of hoisting crane, and especially a kind of hoisting crane is used counter weight device.
Background technology
Counter weight device is that hoisting crane is realized one of major part that load capacity promotes, and the weight of its stability, safety and counterweight is directly connected to the operating efficiency of hoisting crane.At present, little tonnage hoisting crane generally all adopts the version of fixed weight, because the weight of this counterweight is limited, can not adjusts the weight of counterweight according to concrete operation needs flexibly, thereby limit the further lifting of the transaction capabilities of hoisting crane.Existing in prior technology weak point that Here it is.
Summary of the invention
The technical matters that the utility model will solve is exactly not enough to existing in prior technology, and a kind of adjustable balance weight is provided, and the hoisting crane of stable performance is used counter weight device.
This programme is realized through following technical measures: this hoisting crane comprises clump weight with counter weight device; Said clump weight is installed in the support frame; The upper end of support frame is set with sleeve; The lower end of sleeve is provided with clamp handle, and the upper end of sleeve links to each other through link span, is fixed with hanger on the link span; The upper surface of said clump weight is provided with the truncated cone-shaped boss, and the lower surface of clump weight is provided with and the cooresponding counterbore of boss shape; Adjacent two clump weights join through boss and counterbore in the support frame.
For intensity and the stability of strengthening sleeve, between continuous two sleeves, be fixedly connected with reinforced rib.
The beneficial effect of this programme can learn that this hoisting crane is with in the counter weight device according to the narration to such scheme, and clump weight is installed in the support frame; The upper end of support frame is set with sleeve; The lower end of sleeve is provided with clamp handle, and the upper end of sleeve links to each other through link span, is fixed with hanger on the link span; Can adjust the quantity of clump weight like this according to concrete operation needs flexibly; And adjust the position of sleeve easily according to the quantity of clump weight, make the upper edge of clump weight topmost concordant, to strengthen stability and the safety after each clump weight makes up with link span; The upper surface of said clump weight is provided with the truncated cone-shaped boss; The lower surface of clump weight is provided with and the cooresponding counterbore of boss shape; Adjacent two clump weights join through boss and counterbore in the support frame; This connection mode can be carried out axially and location radially each clump weight, to improve its stability and safety.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the structural representation of clump weight among Fig. 1.
Among the figure, 1 is hanger, and 2 is link span, and 3 is reinforced rib, and 4 is sleeve, and 5 is clamp handle, and 6 is support frame, and 7 is clump weight, and 8 is boss, and 9 is counterbore.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below through the specific embodiment, and combine its accompanying drawing, this programme is set forth.
A kind of hoisting crane is used counter weight device, and is as depicted in figs. 1 and 2, and it comprises clump weight 7; Said clump weight 7 is installed in the support frame 6; The upper end of support frame 6 is set with sleeve 4, links to each other to be fixedly connected with reinforced rib 3 between two sleeves 4, and the lower end of sleeve 4 is provided with clamp handle 5; The upper end of sleeve 4 links to each other through link span 2, is fixed with hanger 1 on the link span 2; The upper surface of said clump weight 7 is provided with truncated cone-shaped boss 8, and the lower surface of clump weight 7 is provided with and the cooresponding counterbore 9 of boss 8 shapes; Adjacent two clump weights 7 join through boss 8 and counterbore 9 in the support frame 6.
During use, can after the quantity of clump weight 7 is confirmed,, make the upper edge of the top clump weight 7 concordant according to the quantity of concrete operation needs increase and decrease clump weight 7 with link span 2 through the position of clamp handle 5 regulating sleeves 4.Clump weight 7 keeps boss 8 upwards to be arranged in order in support frame 6; The boss 8 of below clump weight 7 is embedded in the counterbore 9 of top clump weight 7; Form a firm clump weight group, because boss 8 is a truncated cone-shaped, so the axial and radial stability of clump weight group self can be good.
Can pass through existing techniques in realizing without the technical characterictic of describing in the utility model, repeat no more at this.
Claims (2)
