Description

Technical Field

[0001] The utility model relates to a connecting device, in particular to a quick connecting device for a transport traction rope. Background Art

[0002] In common rope transport systems, steel wire ropes are mainly used as traction ropes, and suitable rope joints are required to form a transport loop. The joints need to meet the characteristics of reliable strength and easy disassembly and assembly. In particular, they should not be deformed or damaged when passing through the winch. For small and medium-sized rope transport systems, the winches used are small in size, and the size of the joint connection device is too large and the flexibility is too poor, which will directly affect the stability and reliability of the transportation process. Utility Model Content

[0003] The utility model aims to provide a transport traction rope quick connection device to solve the problems existing in the above-mentioned prior art.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The utility model provides a quick connection device for a transport traction rope, comprising a wire mesh sleeve, a locking piece and a jacket. The inner diameter of the wire mesh sleeve matches the outer diameter of the transport traction rope, the locking piece is a hollow cylinder with a wall thickness of not less than 2 mm, the inner diameter of which is greater than the sum of the outer diameter of the transport traction rope and twice the diameter of the mesh sleeve steel wire, the outer surface of which is smooth and the two ends are chamfered, a through threaded hole is opened at the center of the cylindrical surface, and the wire mesh sleeve can be positioned and fixed at the two ends of the connected transport traction rope by a hexagon socket screw, the inner diameter of the jacket is smaller than the outer diameter of the transport traction rope, and meets the requirement of free passage of the wire mesh sleeve in the initial state, the outer surface of which is smooth and the two ends are chamfered, and the two ends of the inner circle are arc-guided.

[0006] Furthermore, the tensile strength of the wire mesh sleeve is close to that of the transport traction rope, and its two ends are positioned on the two connected transport traction ropes through the locking piece and the screws engaged with the threaded holes. The wire mesh sleeve is inserted into the jacket to achieve radial compression and constraint to increase the friction between the surface of the wire mesh sleeve and the transport traction rope during transportation.

[0007] The utility model has the following beneficial effects: the transport traction rope quick connection device is easy to operate, the tensile strength of the wire mesh sleeve is close to that of the transport traction rope, and different specifications can be selected. Under the action of the jacket, the wire mesh sleeve contracts radially toward the middle in a tightened state, and the friction resistance between it and the transport traction rope increases, which can achieve the effect of "tighter the more you pull". In particular, the wire mesh sleeve has great flexibility and can pass through the winch smoothly without causing deformation and failure at the joint. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be further described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0014] like Figures 1 to 3 As shown, this embodiment provides a transport traction rope quick connection device, including a wire mesh sleeve 2, a jacket 3 and a locking member 4. The wire mesh sleeve 2 is in the shape of a hollow mesh column, and its inner diameter matches the outer diameter of the transport traction rope 1. The tensile strength of the wire mesh sleeve 2 is close to that of the transport traction rope 1; the locking member 4 is a hollow cylinder with a wall thickness of not less than 2 mm, and its inner diameter is greater than the sum of the outer diameter of the transport traction rope 1 and twice the diameter of the mesh sleeve steel wire. Its outer circle surface is smooth and chamfered at both ends. A through threaded hole is opened at the center of its cylindrical surface, and the wire mesh sleeve can be positioned and fixed on the connected transport traction rope 1 by a hexagon socket screw. The inner diameter of the jacket 3 is smaller than the outer diameter of the transport traction rope 1, and meets the free passage of the wire mesh sleeve 2 in the initial state. Its outer circle surface is smooth and chamfered at both ends, and the inner circle is guided by arcs at both ends.

[0015] During installation, first insert one end of the wire mesh sleeve 2 into the part to be connected (left side) of the transport traction rope 1, then screw in the locking piece 4, use an Allen wrench and an Allen screw to position and tighten the wire mesh sleeve 2, then insert the clamping sleeve 3 into the middle free section of the wire mesh sleeve 2, insert the locking piece 4 into the other end of the wire mesh sleeve 2, and insert them into the part to be connected (right side) of the transport traction rope 1 together, use an Allen wrench and an Allen screw to position and tighten the wire mesh sleeve 2, thereby achieving radial compression and constraint of the wire mesh sleeve 2 to increase the friction between the surface of the wire mesh sleeve and the transport traction rope during transportation.

[0016] During disassembly, the screws on the locking member 4 are loosened using an Allen wrench, so that the transport traction rope 1 can be separated from the wire mesh sleeve 2, and then the jacket 3 is separated to complete the rapid disassembly of the transport traction rope joint device.

[0017] The wire mesh sleeve 2, the clamping sleeve 3 and the locking piece 4 can all be reused.
