Description
Technical Field
The utility model belongs to the technical field of crane accessories, and relates to a rope stabilizing device of a crane grab bucket.
Background
The grab crane is a lifting and carrying device for lifting, lowering and carrying heavy objects and bulk materials, and horizontally moving the heavy objects and bulk materials within a short distance. Is a hoisting and carrying device which is indispensable in the production process of industrial and mining enterprises, freight ports, loading and unloading docks. The grab bucket, which is one of important structural members of the crane, is a device for loading and unloading materials. During grab bucket operation, the grab bucket rises and falls along with the winding and unwinding circulation of the lifting rope, and in the process of rising and falling of the grab bucket, the stability of the grab bucket is poor due to the fact that the lifting rope belongs to flexible connection, the grab bucket frequently swings left and right, the grab bucket rotates, the operation effect is seriously affected, the working efficiency is reduced, and economic loss is caused for customers.
Disclosure of utility model
The utility model aims to provide the crane grab rope stabilizing device which is simple in structure and reasonable in design and can effectively avoid rotation of the grab.
The utility model adopts the technical scheme that: the device comprises a crane arm support, a steel wire rope, a grab bucket rope and a grab bucket, and is characterized in that: a winch with a winding drum is arranged at the lower part of one side of the crane boom, and an upper guide wheel with a rope blocking rod is arranged at the upper part of the crane boom; the upper part of the opposite side of the crane boom is provided with a lower guide wheel and a hanging rope stabilizer; the wire rope goes out from the upper part of the winding drum and is connected with the grab bucket rope through an upper guide wheel with a rope blocking roller, a lower guide wheel and a hanging rope stabilizer, and the grab bucket rope is connected with two sides of the grab bucket.
By adopting the structure, when the rope-retaining device is used, the winch with the winding drum drives the speed reducer to rotate through the hydraulic motor, so that the steel wire rope is retracted and paid out according to the working requirement, the steel wire rope bypasses the upper guide wheel, the lower guide wheel and the suspension rope stabilizer of the rope-retaining roller to be connected with the grab bucket rope, and the grab bucket rope is connected to two sides of the grab bucket. When the grab bucket is lifted or descended along with the lifting steel wire rope, the grab bucket rope and the grab bucket follow-up and always keep constant tension, compared with the existing flexible connection, the horizontal swinging phenomenon of the grab bucket can be effectively avoided, the problem of rotation of the existing grab bucket is effectively solved, the operation effect is guaranteed, and the working efficiency is improved. The utility model has simple structure and reasonable design, fills the blank of the device and is worth of being widely popularized and applied.

Fig. 1 is a schematic structural view of the present utility model.
In the figure: 1-winding with a winding drum; 2-a steel wire rope; 3-an upper guide wheel with a rope blocking rod; 4-lower guide wheels; 5-hanging a rope stabilizer; 6-grab rope; 7-crane arm frame.
Detailed Description
As shown, the utility model comprises a crane boom 7, a wire rope 2, a grab rope 6 and a grab. The lower part of one side of the crane arm support 7 is provided with a winch 1 with a winding drum, and the upper part is provided with an upper guide wheel 3 with a rope blocking rod. The upper part of the opposite side of the crane arm support 7 is provided with a lower guide wheel 4 and a suspension rope stabilizer 5. The steel wire rope 2 is discharged from the upper part of the winding drum 1 and is connected with the grab rope 6 through an upper guide wheel 3 with a rope blocking rod, a lower guide wheel 4 and a hanging rope stabilizer 5, and the grab rope 6 is connected at two sides of the grab.
The winch 1 with the winding drum is arranged at the lower part of the crane arm support 7 and close to the hinge point of the turntable, so that the purposes of shortening the length of a hydraulic pipe and facilitating installation and maintenance are achieved.
The winding drum of the winch 1 is provided with a rope pressing device, so that the rope disorder of the steel wire rope 2 can be prevented.
The hanging rope stabilizer 5 is arranged on the crane boom 7 through an installation frame and adjusting installation holes on the crane boom 7, the number of the adjusting installation holes is three at different positions, and the position of the installation frame can be adjusted through different adjusting installation holes, so that the angle of the hanging rope stabilizer 5 is adjusted.
When the winch works, the winch 1 provides a rope stabilizing function, the steel wire rope 2 passes through the hanging rope stabilizer 5, and when the grab bucket ascends, the steel wire rope 2 goes out of the rope around a pulley above the hanging rope stabilizer 5; when the grab bucket descends, the steel wire rope 2 goes out of the rope around the pulley below the hanging rope stabilizer 5, the steel wire rope 2 is connected to two sides of the grab bucket through the grab bucket rope 6, constant tension is kept on the steel wire rope 2 through the control system, and the winch 1 automatically tightens and releases the steel wire rope 2 due to the constant tension in the ascending and descending processes of the grab bucket, so that rotation of the grab bucket is avoided.
