Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire rope tools, in particular to a rope lute head connecting device. Background Art
[0002] At present, in the production of ship transportation and cargo lifting, it is often encountered that ropes need to be connected, and the connected ropes are made of the same or different materials, such as: the connection between wire rope and fiber rope, wire rope and wire rope, or fiber rope and fiber rope. Most of them are now connected using Japanese buckles, circular buckles or knots. After the connection, under the action of the constantly changing magnitude and direction of the rope load force, the contact surface of the wire rope and the fiber rope will produce jumping friction and impact force. The continuous exchange of load and unloading at both ends of the connection causes pulse-like impact (impact) on the contact surface of the rope, causing the rope connection part to be worn and damaged after a short working time until it breaks, causing it to lose its rope connection function and cause safety problems. Summary of the Invention
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a rope pipa head connecting device.

[0006] The first clamping plate and the second clamping plate are both provided with concave-convex engaging teeth.
[0007] The number of the first clamping plates is greater than 2 and is evenly distributed along the length direction of the first clamping plates.
[0008] The second clamping plates are divided into multiple groups, each group is composed of two clamping plates, a rope clamping area is reserved between the two clamping plates, and the width of the rope clamping area is greater than the thickness of the first clamping plate.
[0009] After the above scheme is adopted, the second clamping plate matches the position of the first clamping plate, that is, the first clamping plate is located between the corresponding two second clamping plates to form a mortise and tenon connection. When connecting the ropes, the two rope ends to be connected are respectively passed through the corresponding locking caps (one locking cap is passed through each rope end), the strands of the rope ends are separated to form a lute head, the strands of one rope end are pressed onto the first clamping plate from one end of the first connector, and the strands of the other rope end are pressed onto the first clamping plate from the other end of the first connector. After being pressed in, the strands of the two rope ends are overlapped (or superimposed) with each other; the inner arc surface of the second connector is aligned with the inner arc surface of the first connector and closed (the second clamping plate corresponds to the position of the first clamping plate) for compression (gripping), and the locking caps are engaged from both ends to lock the two ends of the rope, so that the ends of the two ropes can be formed into one, thereby eliminating the friction and impact force generated by the connection between different ropes. After the tapered surface is adopted at the end of the clamping plate, the functions of guiding and gradual locking can be realized. The structure after adopting this scheme is reasonable, the use effect is good, and the connection structure is stable. BRIEF DESCRIPTION OF THE DRAWINGS
