Description

Lifting hook assembly with buffer device

Technical Field

The utility model relates to a hoist technical field especially relates to a lifting hook subassembly with buffer.

Background

The crane is a multi-action hoisting machine for vertically lifting and horizontally transporting heavy objects in a certain range, and is commonly a bridge crane, a bridge frame of the bridge crane longitudinally runs along rails laid on elevated frames on two sides, the space below the bridge frame can be fully utilized for hoisting materials, the materials are not hindered by ground equipment, and the hoisting equipment is characterized by performing intermittent motion.

In the hoist use, the lifting hook is a common hoist in the hoist, and current hoist lifting hook is fixed with the assembly pulley, lacks relevant buffer, especially to fragile, fragile article, and the hoist is originally lifted by crane the impact force big, very easily directly drives article and upwards drunkenness, easily leads to article to damage, influences the safety of lifting by crane of heavy object.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming the defect of prior art, the utility model aims at providing a lifting hook subassembly with buffer, effectual solution lifts by crane in-process fragile article, has the potential safety hazard scheduling problem.

The technical scheme for solving the problem is that the hook component with the buffer device comprises a hook, wherein the hook is vertically connected with a frame in a sliding manner, and the upper end of the frame is fixedly connected with a pulley block;

lifting hook upper end fixed mounting has the fixed block, and the fixed block upper end is fixed with the slide bar, and the slide bar upper end is fixed with the limiting plate that is located the frame, and sliding connection about slide bar and the frame is fixed with the hydraulic cylinder that is located the slide bar left and right sides on the frame, sliding connection has the piston rod about the hydraulic cylinder is internal, and the piston rod upper end is fixed with the backup pad, and the backup pad is located the limiting plate under, installs first pressure spring between backup pad and the limiting plate.

Preferably, the cross section of the sliding rod is square.

Preferably, the piston rod is sleeved with a second pressure spring, and the second pressure spring is positioned between the support plate and the hydraulic oil cylinder.

The utility model discloses more traditional equipment has following benefit: 1) By adopting the three-layer buffer device, under the combined action of the first pressure spring, the hydraulic oil cylinder and the second pressure spring, the inertia impact force generated by the crane for initially lifting the object is effectively buffered, the object is stably lifted, the buffering effect is good, and the safety is high; 2) The structure is ingenious, the cost is low, the practical production is convenient, and the method is economical and practical.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, a hook assembly with a buffer device comprises a hook 1, wherein the hook 1 is connected with a frame 2 in a vertical sliding manner, and the upper end of the frame 2 is fixedly connected with a pulley block 3;

1 upper end fixed mounting of lifting hook has

fixed block

4, 4 upper ends of fixed block are fixed with

slide bar

5, 5 upper ends of slide bar are fixed with the limiting plate 6 that is located frame 2, slide bar 5 and frame 2 upper and lower sliding connection, be fixed with the hydraulic cylinder 7 that is located the 5 left and right sides of slide bar on the frame 2, sliding connection has piston rod 8 about in the

hydraulic cylinder

7, 8 upper ends of piston rod are fixed with backup pad 9, backup pad 9 is located the limiting plate 6 under, install first pressure spring 10 between backup pad 9 and the limiting plate 6.

In order to ensure the stability of the sliding rod 5 sliding up and down in the frame 2, the cross section of the sliding rod 5 is square.

In order to ensure better buffer effect, the piston rod 8 is sleeved with a second pressure spring 11, and the second pressure spring 11 is positioned between the support plate 9 and the hydraulic oil cylinder 7.

The utility model discloses when using, what need explain is, the terms "preceding", "back", "left", "right", "upper", "lower" etc. indicate position or positional relation and use the head view as the benchmark, when lifting hook 1 lifts by crane article, lifting hook 1 drives fixed block 4, slide bar 5 and limiting plate 6 are whole downstream in frame 2, limiting plate 6 extrudees first pressure spring 10 downwards, first pressure spring 10 is in compression state, play first buffering effect, first pressure spring 10 drives backup pad 9 and piston rod 8 downstream in hydraulic cylinder 7, hydraulic cylinder 7 plays second buffering effect to piston rod 8 under the effect of hydraulic oil, backup pad 9 extrudes second pressure spring 11 downwards, play the third buffering effect, the buffer quality who lifts by crane article has effectively been guaranteed, especially lift by crane fragile article, the hoist lifts by crane article initially, under the effect of three-layer buffering, lifting hook 1-layer-based driving article upward movement gradually, alleviate 1-based impact force of lifting hook article initially, the security that lifts by crane article has been improved, high stability, in addition, slide bar 5's cross section is the square, prevent effectively that slide bar 5 from shaking in lifting hook 2 in frame 2, the security of lifting hook has guaranteed about the security of lifting by crane article.
