Description

Technical Field

[0001] The utility model relates to the technical field of transfer and transportation, in particular to a pulling hanging head. Background Art

[0002] When transferring large ring-shaped workpieces, an overhead crane is used for hoisting. During hoisting, a ring-shaped rope is threaded through the ring of the ring-shaped workpiece, and then the other end of the ring-shaped rope is sleeved on the hook. This method is suitable for the transfer of workpieces with a rated length. If the workpiece is relatively long, there will be a problem of insufficient rope length. Moreover, when connecting the rope and the hook, the position of the hook needs to be precisely controlled, thus increasing the difficulty of hoisting and transferring. And during the hoisting process, the workpiece is prone to swing on the rope, which is likely to cause safety accidents. Content of the Utility Model

[0003] The utility model provides a pulling hanging head to solve the above-mentioned deficiencies of the prior art. It can conveniently replace the rope according to different usage scenarios, and at the same time, it is convenient for fixing operations during hoisting, with strong practicability.

[0004] In order to achieve the purpose of the utility model, the following technology is proposed:

[0005] A pulling hanging head includes a cross bar. Waist-shaped holes are opened at both ends of the cross bar. A hanging plate is provided on the cross bar, and a hanging hole is opened on the hanging plate. The hook on the overhead crane is threaded through the hanging hole, or the towing rope of the overhead crane is directly fixed on the hanging hole. Connecting screws are threaded through the waist-shaped holes. Concave plates are respectively provided at both ends of the connecting screws. Through holes are opened at the lower ends of the concave plates. A cable is provided on the through hole of one of the concave plates. A terminal cap is provided at the other end of the cable. The other end of the cable passes through the through hole of the other concave plate. A terminal plate is provided at the lower end of the other concave plate. A rectangular opening is opened on the terminal plate. A concave clamping member is clamped at the lower end of the other concave plate. A U-shaped opening is opened on the concave clamping member. The cable passes through the U-shaped opening. A terminal post is provided at the open end of the concave clamping member. A pair of clamping bars are provided between the terminal post and the terminal plate. A terminal connecting plate is provided at one end of the clamping bar. One of the concave plates is used for fixing one end of the cable. This fixing is stable and locked, and when connecting the cable and the ring-shaped workpiece, the connection will not be cancelled. And the other concave plate is used for fixing the other end of the cable. This fixing is a movable fixing, so that one end of the cable is in a movable state, thus facilitating the cable to be threaded through the ring-shaped workpiece and fixing the other end of the cable on it. When fixing, the terminal cap of the cable is blocked by the concave clamping member, and the concave clamping member is positioned by the provided clamping bars to ensure the stability after fixing.

[0006] Further, a shrinkage tube is provided at the lower end of one of the concave plates. A thread is provided at the upper end of the outer periphery of the shrinkage tube. A conical ring is formed at the lower end of the outer periphery of the shrinkage tube. The upper end of the conical ring is the small end. A shrinkage slit is provided at the lower end of the outer periphery of the shrinkage tube. The upper end of the shrinkage tube is connected with a wire sleeve through the thread. An inner pressure ring is provided at the lower end of the wire sleeve. The lower end of the inner pressure ring is of a conical structure, and the inner wall of the lower end of the inner pressure ring is closely attached to the outer periphery of the conical ring. One end of the cable is inserted into the shrinkage tube. By rotating the wire sleeve, the shrinkage tube can be shrunk, and one end of the cable can be stably fixed through the shrinkage tube. In order to improve the stability after fixation, a plurality of anti-slip teeth can be provided on the inner wall of the shrinkage tube. Through this setting method, it is convenient to replace the cable.

[0007] Further, a U-shaped groove is provided on the end connection plate. A limit baffle is provided at the inner end of the end connection plate. A connection column is provided in the U-shaped groove. The connection column is provided on the end plate. An inner pressure spring is sleeved on the outer end of the connection column. A rotating clamping plate is provided at the inner end of the inner pressure spring. The rotating clamping plate is located outside the limit baffle. Through the provided rotating clamping plate, when it is in a vertical posture, the rotating clamping plate can act on the outside of the limit baffle, so as to fix the end connection plate.

[0008] Further, a pair of vertical holes are provided on the hanging plate. A connection screw is inserted into the vertical holes. Vertical plates are provided at both ends of the connection screw. An arc plate is provided at the lower end of the vertical plate. Through the provided arc plate, it can be sleeved on the workpiece to restrain the workpiece, and it needs to be replaced according to the outer diameter of the workpiece to ensure the limiting effect.

[0009] The advantages of the above technical solutions are as follows:

[0010] The utility model is convenient for the fixing operation during the lifting and transfer of the annular workpiece, and by selecting cables of different lengths, the applicable range is expanded. Description of the Drawings
