Abstract

The utility model relates to a hoisting mechanism with a rigid-orientation telescopic barrel for a crane. The hoisting mechanism comprises a fixed barrel body, a movable pulley block and a steel wire rope, wherein the upper part of the fixed barrel body is fixed with the lower part of a trolley frame; a first telescopic barrel body capable of extending and retracting is arranged in the fixed barrel body; a second telescopic barrel body capable of extending and retracting is arranged in the first telescopic barrel body; a flange is fixedly arranged on the lower part of the second telescopic barrel body; the lower part of the flange is fixedly connected with a lifting hook; the movable pulley block is fixedly connected with the flange; the movable pulley block is arranged in the telescopic barrel bodies; the steel wire rope is unreeled by the hoisting mechanism; the steel wire rope sequentially penetrates through the fixed barrel, the first telescopic barrel body and the second telescopic barrel body to be connected with the movable pulley block in the second telescopic barrel body; the hoisting mechanism with the rigid-orientation telescopic barrel for the crane has the beneficial effects that when the crane is used for hoisting goods, the swinging of a lifting appliance is effectively stopped, and the accurate positioning of the lifting appliance is realized.

Description

The crane hoisting mechanism that has rigidity guiding telescopic shaft

Technical field

The utility model relates to a kind of crane hanger, relates in particular to the hanger structure in this hoisting crane.

Background technology

In the industry of some special use weight-hauling equipmenies, like the part hoisting crane of used in nuclear power station, harsh requirement is rocked in the accurate location of handling article and restriction suspender, and the manufacturing and designing of present hoisting crane industry shorter mention this respect.

The utility model content

The utility model technical issues that need to address have provided a kind of crane hoisting mechanism that has rigidity guiding telescopic shaft, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:

The utility model comprises: fixed cylinder; The bottom of described fixed cylinder top and trolley frame is fixed; In described fixed cylinder, settle the retractable first flexible cylindrical shell; In the described first flexible cylindrical shell, settle the retractable second flexible cylindrical shell; Bottom fixed in position one flange at the described second flexible cylindrical shell; Captive joint one suspension hook in described flange bottom; Also comprise: captive joint one running block on described flange; Described running block is in the inside of flexible cylindrical shell; Also comprise: the steel rope of transferring by lifting mechanism; Described steel rope passes fixed muffle, the first flexible cylindrical shell successively and in the second flexible cylindrical shell, links to each other with running block.

Compared with prior art, the beneficial effect of the utility model is: when the crane for hoisting article, effectively prevented rocking of suspender, and can realize the accurate location of suspender.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the birds-eye view of Fig. 1.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

Visible by Fig. 1, Fig. 2: the utility model comprises: fixed cylinder 3; The bottom of described fixed cylinder 3 tops and trolley frame 2 is fixed; In described fixed cylinder 3, settle the retractable first flexible cylindrical shell 4; In the described first flexible cylindrical shell 4, settle the retractable second flexible cylindrical shell 5; Bottom fixed in position one flange 6 at the described second flexible cylindrical shell 5; At described flange 6 bottom captive joints one suspension hook 8; Also comprise: captive joint one running block 7 on described flange 6; Described running block 7 is in the inside of flexible cylindrical shell 5; Also comprise: the steel rope 1 of transferring by lifting mechanism; Described steel rope 1 passes fixed muffle 3, the first flexible cylindrical shell 4 successively and in the second flexible cylindrical shell 5, links to each other with running block 7.

The utility model principle of work is: during lifting mechanism lifting article, steel rope 1 rises, and drives running block 7 and rises; Follow rising with running block 7 flange connecting 6, flange 6 drives suspension hook 8 and rises, and the second flexible cylindrical shell 5 is to the first flexible cylindrical shell 4 inner indentations; After the indentation fully, the first flexible cylindrical shell 4 and the second flexible cylindrical shell 5 are simultaneously to fixed cylinder 3 inner indentations, after the indentation fully; Promptly reached desired lifting altitude, higher like lifting altitude, can increase flexible cylindrical shell again.Each cylindrical shell adopts round steel pipe to make; The gap is very little between each cylindrical shell, has guaranteed whole rigidity in horizontal all directions, has so just limited suspender rocking in horizontal all directions; Guaranteed the relative position of suspension hook 8 simultaneously, just realized the accurate location of suspender at vertical direction.Can get final product according to above-mentioned course of action backstepping during the decline suspender.

Claims (1)
