Description

A kind of railway run-through ground line manufacture traction hook

Technical field

The utility model relates to a kind of railway run-through ground lines to manufacture with traction hook.

Background technique

Seamless railway Through ground wire is by closely one layer of anti-corrosion alloy sheath of cladding forms outside twisted copper conductors, manufacturing process packet Sheath is included to align, reeve, drawing the subsequent processings such as stranded conductor, the molding of alloy sleeve mold, annealing.

Stranded conductor is towed cable traction during alloy sleeve is walked, stranded conductor by torsion internal stress, It is easy to rotate in alloy sleeve, causes stranded conductor loose, and cause traction tired with the increase of alloy sleeve frictional force Difficult and tensile phenomenon directly results in production efficiency reduction.

Utility model content

The purpose of this utility model is in view of the problems of the existing technology to provide a kind of manufacture of railway run-through ground line with leading Draw hook.

The specific technical solution of the utility model is as follows:

A kind of railway run-through ground line manufacture traction hook, including the first hook, the second hook, joint ball, inside are arc Shape covers the guide sleeve for covering set, both ends perforation in face, and the set that covers is set in guide sleeve, and the joint ball is set to pressure In sheathing, first hook and the second hook are stretched to cover respectively by guide sleeve both ends and be connect in set with joint ball；

Further, the gland body for covering and being involuted by two that covers forms；

Further, the guide sleeve outer wall is spherical outer wall；

Further, first hook is opposite with the opening direction of the second hook.

The utility model has the following beneficial effects:

The utility model using can it is axial 360 ° rotation first hook and second hook, as stranded conductor and traction rope The attachment device of rope can effectively offset stranded conductor by torsion internal stress, effectively prevent stranded conductor in alloy sleeve Rotate the problem for causing its loose.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

A kind of railway run-through ground line manufacture as shown in Figure 1 is linked up with traction, including first links up with the 1, second hook 2, closes Section ball 3, the internal guide sleeve 5 for covering set 4, both ends perforation that face is covered for arc, the set 4 that covers are set in guide sleeve 5, The joint ball 3, which is set to, to be covered in set 4, and first hook 1 and the second hook 2 stretch to pressure by 5 both ends of guide sleeve respectively It is connect with joint ball 3 in sheathing 4, described cover covers the gland body that 4 are involuted by two and form, and 5 outer wall of guide sleeve is The opening direction of spherical outer wall, first hook 1 and the second hook 2 is opposite.

The specific work process for carrying out wire rope handling operation in alloy sleeve using the utility model strand conductor is as follows:

Stranded conductor is connect with the first hook 1, drag rope is passed through in alloy sleeve and connect with the second hook 2, is drawn Rope take-up, so that the utility model is walked along alloy sleeve drives stranded conductor wire rope handling, the first hook 1 and the second hook 2 By joint ball 3, it is set to be oppositely oriented the axial 360 ° of rotations of set 5, and radially there is certain deflection angle, in alloy The first hook 1 and the opposite flexible rotating of the second hook 2, prevent stranded conductor torsion in distraction procedure from making during walking in sheath At the generation of loose problem, 5 outer wall of guide sleeve is reduced the utility model and is walked the friction walked in alloy sleeve using spherical outer wall Power, prevent traction hook it is stuck in alloy sleeve, guarantee traction everything goes well with your work carry out.
