Description

A special clamp for hoisting box and board goods

technical field

The utility model relates to a clamp used for loading and unloading box and board goods in a port, which belongs to the technical field of lifting tools.

Background technique

At present, there are usually two hoisting methods used by ports when loading and unloading box and board goods: one is to use hoisting belts for hoisting, and the other is to use steel plate clamps for clamping and hoisting. There is no harm to the goods when hoisting with slings, but due to the sharp edges and corners of the box board, the slings must be protected during hoisting, otherwise the slings will be easily cut off, causing accidents, which not only reduces the operating efficiency, but also consumes a lot of tools and accessories; use When the steel plate clamps work on the box plate, it often causes damage to the contact part between the box plate and the clamp, causing losses to the user, and even a claim accident, which affects the economic benefits and reputation of the port and is not conducive to the development of the port. Therefore, it is very necessary to improve the hoisting tools of box-board goods.

The technical scheme that solves the above problems is:

A special clamp for hoisting box and board goods, which includes a clamp body, a pulley, a pulley shaft, and a polyurethane plate. The clamp body is a box structure welded by steel plates. The upper part of the box structure of the clamp body is a beam, and the middle part is a column. The lower part is the clamp hook, the beam and the clamp hook are located on the same side of the column, the beam and the clamp hook are connected vertically to the column, the end of the beam far away from the column is equipped with a pulley, and the pulley shaft is connected to the plane of the clamp body composed of the beam, column and clamp hook Vertically, the lower bottom surface of the beam, the upper surface of the clamp hook and the inner surface of the same side of the column are respectively embedded with polyurethane boards. The width of the polyurethane board matches the width of the lower bottom surface of the beam, the upper surface of the clamp hook and the inner surface of the column.

The above-mentioned special clamp for lifting box-like goods, the two outer steel plates at the front end of the beam box at the end of the clamp body beam far away from the column extend forward, and the extended two outer steel plates have shaft holes on the plate surface, and the pulley shaft is embedded. Installed in the shaft hole, the pulley shaft is perpendicular to the surface of the extended two outer steel plates, there is a gap between the front end of the beam box and the opposite pulley edge, and the steel wire rope passes through the gap and is wound on the pulley.

In the special clamp for hoisting box-like goods, the polyurethane plate is fixed on the lower bottom surface of the beam, the upper surface of the clamp hook and the inner surface of the column by bolts, and the bolt cap is embedded in the surface of the polyurethane plate.

The beneficial part of the utility model is:

The utility model installs a polyurethane plate on the contact surface between the clamp body and the box plate goods, and the edge of the box plate goods will not cause damage to the goods when it contacts with the soft material-polyurethane plate, and avoids the rigidity of the original steel plate clamps The damage to the goods caused by contact increases the safety factor compared with the sling hoisting method; at the same time, a pulley is installed on the upper part of the clamp body, and the wire rope closes the clamps on both sides to the middle through the pulley to clamp the box and board goods. Reduced labor intensity of workers.

The utility model has the advantages of simple structure and convenient use, avoids the damage to the box board goods in the hoisting process, improves the hoisting efficiency and hoisting quality, and has remarkable economic benefits.

detailed description

The utility model is made up of pliers body 1, pulley 2, pulley shaft 3, polyurethane plate 4, bolt 5.

FIG. 1 shows that the pliers 1 is a box structure welded by steel plates. The box structure can reduce the overall weight and volume of the pliers 1 and improve the bending strength of the pliers 1 . The upper part of the box structure of the clamp body 1 is a beam, the middle part is a column, and the bottom is a clamp hook. The beam and the clamp hook are located on the same side of the column, and the beam and the clamp hook are vertically connected to the column. During production, the beam side wall, the column side wall and the pincer hook side wall of the clamp body 1 are integrally cut and formed by steel plates, and the top surface, front wall, The rear wall and the bottom surface form the overall structure of the pliers box.

Figure 1 shows that the two outer steel plates at the front end of the beam box at the end of the pliers 1 beam away from the column extend forward, and there are shaft holes on the plates of the extended two outer steel plates, and the pulley shaft 3 is embedded in the shaft hole. Wheel shaft 3 is perpendicular to the plate surfaces of the two outer steel plates extending, there is a gap between the front end of the beam box body and the relative pulley 2 edge, and steel wire rope 6 passes through the gap and is wound on the pulley 2. Adopting the pulley 2 structure is beneficial to the sliding of the steel wire rope 6 on the clamp, which not only protects the steel wire rope 6, prolongs the service life of the steel wire rope, but also facilitates the operation of workers.

Figure 1 shows that the lower bottom surface of the beam, the upper surface of the clamp hook and the inner surface of the same side of the column are respectively embedded with polyurethane board 4, and the width of the polyurethane board 4 is the same as that of the lower bottom surface of the beam, the upper surface of the clamp hook and the inner surface of the column. match. The soft material-polyurethane plate 4 will not cause damage to the goods in contact with the box plate, and avoids the damage to the goods caused by the rigid contact of the original steel plate clamps.

Figure 1 shows that the polyurethane plate 4 is fixed on the bottom surface of the crossbeam of the clamp body 1, the upper surface of the clamp hook and the inner surface of the column by bolts 5, and the bolt caps are embedded in the surface of the polyurethane plate 4 to prevent the bolt caps from touching the box plate 8. scratches.

Fig. 2 shows that the utility model is used in conjunction with steel wire rope 6 and support bar 7. Every steel wire rope 6 is corresponding to a pair of clamps, and two clamps are positioned at the both sides of box plate 8 respectively, and the pincers hook of clamp body is opposite, and the pincers hook is stuck on the side edge of box plate 8. A plurality of steel wire ropes 6 and clamps are hoisted on a support bar 7, and the number of steel wire ropes 6 and clamps is reasonably selected according to the length of the goods during hoisting.
