Description

Port crane lifting head capable of self-clamping

Technical Field

The utility model relates to the technical field of cranes, in particular to a port crane head capable of self-clamping.

Background

The crane is popular name of a crane and is widely applied to ports. The crane mainly uses a hook to hoist objects, and the hook is often hung on a steel wire rope of a hoisting mechanism in the crane by means of pulley blocks and other parts.

The general lifting hook is C-shaped and is used for hooking objects or tying ropes of objects, but the existing lifting hook cannot lock and fix the hooked objects or ropes, and the lifted objects or ropes often slip on the lifting hook. In view of this, we propose a self-clamping harbour crane head.

Preferably, the two sides of the inner bottom surface of the lifting hook are provided with arc edges.

Preferably, the power source is composed of a sliding rod, a screw rod and a motor.

Preferably, the motor is fixedly installed on the lifting hook, and the screw rod is fixedly connected with the output end of the motor through a coupler.

Preferably, two ends of the sliding rod are mounted on the inner side of the lifting hook, the locking block penetrates through the sliding rod, and a threaded hole is formed in the locking block.

Preferably, the screw rod is installed in the threaded hole, and the screw rod and the sliding rod are parallel to each other.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, by the locking and fixing device, the lifted object or rope is automatically clamped, the lifted object or rope is prevented from moving between the bottom surface of the inner side of the lifting hook and the locking block, and the slipping phenomenon between the lifting hook and the lifted object or rope is effectively prevented.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-3, the present utility model is described in detail by the following embodiments:

the utility model provides a but harbour loop wheel machine lifting head of self-holding, includes lifting hook 2, and lifting hook 2's top fixed mounting has connecting rod 1, and connecting rod 1 hangs on hoisting mechanism's wire rope in the loop wheel machine with the help of components such as assembly pulley, is equipped with the rope groove on lifting hook 2's the inboard bottom surface for guide by the object or the rope that lift by crane get into the rope inslot, be equipped with the circular arc limit on lifting hook 2's the inboard bottom surface both sides for reduce lifting hook 2 and by the shearing force between the object or the rope that lift by crane, lifting hook 2's inboard is equipped with locking fixing device.

In this embodiment, the locking fixing device is formed by a locking block 3, one side of the locking block 3 is provided with a power source for driving the locking block 3 to be close to or far away from the inner bottom surface of the lifting hook 2, the power source is formed by a sliding rod 4, a screw rod 5 and a motor 6, the screw rod 5 and the sliding rod 4 are parallel to each other, the sliding rod 4 is obliquely arranged rightwards, the motor 6 is fixedly arranged on the lifting hook 2, and the output ends of the screw rod 5 and the motor 6 are fixedly connected through a coupling.

In this embodiment, the both ends fixed mounting at slide bar 4 in the inboard of lifting hook 2, and the locking piece 3 passes slide bar 4, and the locking piece 3 removes along slide bar 4, is equipped with screw hole 7 in the locking piece 3, and screw 5 screw thread is installed in screw hole 7, screw 5 and lifting hook 2 swing joint.

In this embodiment, when the crane uses the hook 2 to lift an object, the hook 2 is firstly used to pass through the object or bind the rope for the object, then the object or the rope can slide down along the inner bottom surface of the hook 2 along with the lifting of the hook 2, enter the rope groove, limit the object or the rope to slide back and forth on the inner bottom surface of the hook 2, and simultaneously start the motor 6, the output end of the motor 6 drives the screw 5 to rotate clockwise rapidly, so that the locking block 3 moves downwards along the slide bar 4 until the locking block 3 is pressed by the lifted object or the rope to fix the inner bottom surface of the hook 2, thereby realizing automatic clamping of the lifted object or the rope, avoiding the sliding phenomenon between the hook 2 and the lifted object or the rope, and effectively preventing the locking block 3 from gradually moving away from the inner bottom surface of the hook 2 and the lifted object or the rope when the output end of the motor 6 drives the screw 5 to rotate anticlockwise.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present utility model, and are not intended to limit the utility model, and that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
