Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting tools, in particular to a rope saw capable of preventing rotation of string beads. BACKGROUND

[0002] The string bead rope saw is suitable for cutting and processing various hard materials, and is mainly applied to the fields of stone mining, rough material shaping, plate cutting and profiled cutting and processing, and has many advantages such as high material utilization rate, high cutting efficiency, ability to make large plates and profiled processing, environmental protection and the like in cutting materials.

[0003] The existing rope saw comprises a steel wire rope, diamond string beads fixedly sleeved on the steel wire rope, springs abutting against end faces of adjacent two diamond string beads, and a fixing layer covering the springs and fixing the diamond string beads, the fixing layer being formed by injection molding or vulcanization. In the existing rope saw, ordinary springs are used to limit the diamond string beads, since the end faces of the ordinary springs and the end faces of the diamond string beads are in contact through a plane, the anti-rotation limiting effect of the ordinary springs on the adjacent diamond string beads is low, and after being used for a period of time, the diamond string beads are prone to relative rotation with the steel wire rope, that is, the diamond string beads cannot be fixed well, thereby causing the service life of the rope saw to be relatively short, and thus further improvement is needed. CONTENT OF THE UTILITY MODEL

[0004] In order to enhance the anti-rotation capability of the diamond string beads, the present application provides a rope saw capable of preventing rotation of string beads.

[0005] The rope saw capable of preventing rotation of string beads provided by the present application adopts the following technical scheme:

[0006] The rope saw capable of preventing rotation of string beads comprises a steel wire rope, a plurality of string bead bodies fixedly sleeved on the steel wire rope, springs sleeved on the steel wire rope and located between adjacent two string bead bodies, and a fixing layer covering the springs, an outer end face of the string bead body is provided with a limiting slot, and both ends of the spring are protrusively provided with limiting plug tails inserted into the limiting slot.

[0007] By adopting the above technical scheme, the string bead body is fixed by the limiting slot and the limiting plug tails of the spring, and is fixed by mutual embedding, so that the string bead body is fixed in a circumferential direction, and relative rotation between the string bead body and the steel wire rope is effectively prevented, and the stability and durability of the rope saw are improved.

[0008] Preferably, the string bead body comprises a base sleeve and a diamond abrasive layer fixedly sleeved on the base sleeve, the base sleeve is fixedly sleeved on the steel wire rope, the outer end faces of both end portions of the base sleeve protrude from the outer end face of the diamond abrasive layer respectively, the outer diameter of the base sleeve is smaller than the outer diameter of the diamond abrasive layer, and the limiting slot is formed in the outer end face of the base sleeve.

[0009] Preferably, the limiting grooves are communicated with the outer peripheral wall and the inner peripheral wall of the base sleeve, and a plurality of limiting grooves are arranged circumferentially around the base sleeve.

[0010] By adopting the above technical scheme, the limiting grooves are provided in plurality, on one hand, facilitating assembly of the spring, and on the other hand, increasing the contact area between the fixing layer and the base sleeve, and enhancing the connecting strength between the string-bead body and the fixing layer.

[0011] Preferably, the width dimension of one end of the limiting groove close to the diamond abrasive layer is greater than the width dimension of the other end of the limiting groove away from the diamond abrasive layer, so that the limiting groove is in the form of a dovetail groove.

[0012] By adopting the above technical scheme, the fixing layer is filled into the limiting groove, so that the contact area between the base sleeve and the fixing layer is increased, and the corresponding bonding force is also increased, so that the string-bead body and the fixing layer are not prone to rotating.

[0013] Preferably, the inner peripheral wall of the base sleeve has a clamping protrusion.

[0014] By adopting the above technical scheme, the inner peripheral wall of the base sleeve has the clamping protrusion, the clamping protrusion increases the contact area between the base sleeve and the fixing layer, so that the connection between the string-bead body and the steel wire rope is more stable, and the relative rotation between the string-bead body and the steel wire rope is further prevented.

[0015] Preferably, the cross section of the clamping protrusion is triangular.

[0016] By adopting the above technical scheme, the cross section of the clamping protrusion is triangular, which can further enhance the connecting strength between the base sleeve and the fixing layer, so that the connection between the base sleeve and the steel wire rope is more firm, thereby better preventing the string-bead body from rotating.

[0017] Preferably, a screw hole is arranged through the outer peripheral wall of the base sleeve in the radial direction, the base sleeve is provided with a jackscrew which is screwed into the screw hole, and the end of the jackscrew abuts against the outer wall of the steel wire rope.

[0018] By adopting the above technical scheme, after the base sleeve is sleeved on the steel wire rope, the jackscrew is tightened, so that the jackscrew abuts against the outer wall of the steel wire rope, and the pre-fixing of the string-bead body is realized through the extrusion friction force.

[0019] Preferably, the fixing layer is covered on the nut of the jackscrew.

[0020] By adopting the above technical scheme, the jackscrew increases the contact area between the base sleeve and the fixing layer, and improves the connecting strength between the string-bead body and the fixing layer.

[0021] Preferably, the end of the jackscrew is provided in the form of a pointed end, the steel wire rope is a steel strand rope in which a plurality of steel wires are spirally twisted, and the pointed end of the jackscrew can be embedded into the gap between the strands of the steel strand rope.

[0022] By adopting the above technical solution, when tightening the top screw, the tip will squeeze the outer steel wire, forcing the local steel wire to deform slightly, and then embed into the gap between the strands to achieve axial positioning of the main body of the bead through "compression friction + gap fitting", thus preventing the main body of the bead from rotating or moving.

[0023] In summary, this utility model has the following beneficial effects:

[0024] 1. The main body of the bead string is fixed by the limiting groove and the limiting plug of the spring, forming a mutually embedded and fixed structure. This strengthens the circumferential rotation of the main body of the bead string, effectively preventing relative rotation between the main body of the bead string and the wire rope, and improving the stability and durability of the wire saw.

[0025] 2. Multiple limiting grooves are provided. On the one hand, this facilitates the assembly of the spring. On the other hand, it increases the contact area between the fixing layer and the base sleeve, thereby enhancing the connection strength between the bead body and the fixing layer.

[0026] 3. When tightening the top screw, the tip will squeeze the outer steel wire, forcing the local steel wire to deform slightly, and then embed into the gap between the strands. Through "compression friction + gap fitting", the axial positioning of the main body of the bead is achieved, preventing the main body of the bead from rotating or moving.
