Description

Fixing and adjusting device for steel wire rope of crane grab bucket

Technical Field

The application relates to the technical field of crane equipment, in particular to a fixing and adjusting device for a steel wire rope of a crane grab bucket.

Background

As an important flexible force transmission mechanism of a crane grab bucket, the steel wire rope has high requirements on the strength, flexibility and wear resistance of the material, and the design of a crane grab bucket pulley system pulled by the steel wire rope also needs to correct all structures which possibly damage the steel wire rope as much as possible.

Because hoist grab bucket wire rope is in the consideration of extension wire rope life, all be in a relative pine of taking off and vertical flagging state in most time, often can appear along with using the slippage to the assembly pulley convex surface, and block in the middle of the gap of assembly pulley and grab bucket body, this kind of derail and flee the rail trouble and frequently appear in the middle of the hoist grab bucket operation process, repair the difficulty and have certain quality hidden danger, can't effectively inspect when the distance is too far away, can lead to wire rope to block the fracture or take off the pine and cause the incident even when serious. The steel wire rope must be stably positioned at the groove position of the pulley block, so that the normal and stable operation of the whole crane grab bucket can be smoothly maintained.

Disclosure of Invention

In order to solve the problem, the utility model discloses the structure provides an idea of using standard component and from the finished piece combination, can stabilize the wire rope position of grab bucket assembly pulley, and the commonality is good, convenient to use, and easy dismantlement reforms transform the cost lower.

The utility model provides a fixed adjusting device of crane grab bucket wire rope, includes two band steel insurance pieces, two portal trestles, a plurality of band steel gasket, and two portal trestles are fixed in crane grab bucket assembly pulley both sides, and the band steel insurance piece is fixed above the portal trestles, towards assembly pulley one side, and the band steel gasket is arranged in between band steel insurance piece and the portal trestle for adjust the clearance between band steel insurance piece and the portal trestle. The flat steel safety piece is in a continuous arch shape, the height of the arch is 2 times higher than the diameter of the steel wire rope of the pulley, and the length of the arch exceeds the thickness of the pulley by 100-200 mm. The gantry support is of an L-shaped angle steel structure.

The beneficial effect of this application: through the external fixing device, the abrasion condition of the steel wire rope is effectively reduced, the damage maintenance and replacement caused by the groove disengagement or the clamping of the steel wire rope are reduced, the maintenance cost is saved, and the labor intensity of maintenance personnel is reduced. This application simple structure, it is convenient to reform transform, and the cost is lower, and the commonality is good, can not only use in crane grab bucket aspect, does obtain useful application in all kinds of assembly pulley wire ropes, easily promotes, has comparatively wide market prospect.

Detailed Description

In order to more clearly describe the embodiments of the present invention, the drawings required in the embodiments will be briefly described below. It should be understood that the drawings in the following description are exemplary only, and that the structures, proportions, sizes, etc. are shown only for the purpose of illustration and are not intended to limit the implementation conditions of the present device, which is not technically practical.

The utility model provides a fixed adjusting device of crane grab bucket wire rope, includes two band steel insurance pieces 3, two gantry support 4, a plurality of band steel gasket 6, and two gantry support 4 are fixed in 8 both sides of assembly pulley of crane grab bucket 7, and band steel insurance piece 3 is fixed in gantry support 4 top, towards assembly pulley 8 one side, and band steel gasket 6 is arranged in between band steel insurance piece 3 and gantry support 4 for adjust the clearance between band steel insurance piece 3 and gantry support 4. The flat steel safety part 3 fixed by the hexagonal head bolt 1 and the hexagonal head nut 2 is in a continuous arch shape, the height of the arch is 2 times higher than the diameter of the pulley block steel wire rope 5, and the length exceeds the thickness of the pulley by 100-200 mm. The gantry support 4 is made of L-shaped equal-edge angle steel.

After the assembly is completed, the flat steel safety part 3 fixes the positions of the steel wire ropes of the pulley block 8, so that the steel wire ropes of the pulley block 5 are not broken due to derailment and rail jumping, the positions of the steel wire ropes 5 can be adjusted by adjusting the flat steel safety part 3, and a plurality of groups of new flat steel snap rings can be added below the transverse gantry support 4, so that the steel wire ropes 5 are prevented from slipping and shifting in grooves of the pulley block 8.

Fig. 1 shows an example of the fixing and adjusting device for the pulley block, which is a preferred embodiment of the device, fig. 2 is a partially enlarged view schematically illustrating the connection effect between the fixing device and the grab bucket 7 of the crane, and the rest of the device except for the flat steel safety piece 3 mainly used for preventing loosening and the gantry support 4 which are self-made pieces are standard pieces, and can be produced in batches in a standard manner, and the adjustment and the manufacture are carried out according to the description of fig. 3 and fig. 4 and the corresponding specifications.

Fig. 2 is a front view of the present device for fixing and adjusting a wire rope of a crane grab bucket, which is a preferred embodiment:

(1) the flat steel safety piece 3 is a self-made piece, the manufacturing needs to be firm and free, the rest parts can be standard pieces or can be workpieces added for the standard pieces, the flat steel safety piece can be designed and manufactured according to the standard pieces with corresponding specifications, and batch standard production can be realized.

(2) The gantry support 4 and the crane grab bucket pulley block 8 are connected through bolts, so that adjustment is convenient, and welding can be selected according to actual conditions.
