Abstract
The utility model discloses a change hydraulic tensioner tension pulley with low costs, tension pulley annular surface is equipped with annular nylon piece, and annular nylon piece upper surface is equipped with a plurality of annular channels, annular nylon piece is formed by the concatenation of a plurality of arc nylon pieces, is equipped with the shoulder hole that a plurality of rows of equidistant arranged on the arc nylon piece, and tension pulley annular surface is equipped with the waist type hole supporting with the shoulder hole, and the length direction and the annular channel direction in waist type hole are unanimous, and the screw passes shoulder hole and waist type hole and screws fixedly with arc nylon piece and tension pulley through the nut. The utility model discloses when the annular nylon piece on well tension pulley annular surface has the part to damage, can change one of them arc nylon piece, the replacement cost is low, because arc nylon piece can produce some deformations along with the lapse of time after the production is accomplished, can't accurate and the original connecting hole of tension pulley annular surface is accurate when leading to the later stage to change arc nylon piece, so set up the connecting hole into the just back-end change in waist type hole rear.
Description
Technical Field
The utility model relates to an electric power transmission field especially relates to a hydraulic tension machine tension pulley that replacement cost is low.
Background
The tensioner is a device for the tension stringing of the power transmission line and the erection of the high-altitude cableway, when the construction operation of the mechanical traction stringing of the power transmission line, in order to ensure that the wire is not contacted with the ground and various ground facilities when being unfolded, the wire is ensured not to be damaged, an acting force opposite to the direction of the traction unfolding must be always applied to the wire in the process of unfolding the wire, the tensioner is born from this, the tensioner rubs with the wire in the long-term use process, the annular nylon block on the annular surface of the tensioner is easy to wear, the cost of the annular nylon block is higher, the whole replacement price is higher, and the annular nylon block replaced at the later stage is difficult to align with the original linking hole of the annular nylon block of the tensioner, and the replacement is difficult.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a change with low costs hydraulic tensioner tension pulley.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that: the utility model provides a change hydraulic tensioner tension pulley with low costs, tension pulley annular surface is equipped with annular nylon piece, and annular nylon piece upper surface is equipped with a plurality of annular channels, annular nylon piece is formed by the concatenation of a plurality of arc nylon pieces, is equipped with the shoulder hole that a plurality of rows of equidistant arranged on the arc nylon piece, and tension pulley annular surface is equipped with the waist type hole supporting with the shoulder hole, and the length direction and the annular channel direction in waist type hole are unanimous, and the screw passes shoulder hole and waist type hole and screws fixedly with arc nylon piece and tension pulley through the nut. The utility model provides a when the annular nylon piece on tension pulley annular surface has the part to damage, can change one of them arc nylon piece, the replacement cost is low, because the arc nylon piece can produce some deformations following the lapse of time after the production is accomplished, can't accurate and the original connecting hole of tension pulley annular surface is accurate when leading to the later stage to change arc nylon piece, so set up the connecting hole into waist type hole rear just later stage and change.
Further, a gap exists at the joint of the two adjacent arc-shaped nylon blocks. The arc nylon block can generate some deformation along with the change of time, and the gap at the joint leaves a space for the deformation of the arc nylon block.
Further, the gap between the joints of the two adjacent arc-shaped nylon blocks is 0.5-1 cm.
Furthermore, the annular nylon block is formed by splicing 8-12 arc nylon blocks. Is beneficial to production and installation.
Further, the stepped holes have 3 rows of 3 holes each. The fixation is firmer.
The utility model has the advantages that:
the utility model discloses when the annular nylon piece on well tension pulley annular surface has the part to damage, can change one of them arc nylon piece, the replacement cost is low, because arc nylon piece can produce some deformations along with the lapse of time after the production is accomplished, can't accurate and the original connecting hole of tension pulley annular surface is accurate when leading to the later stage to change arc nylon piece, so set up the connecting hole into the just back-end change in waist type hole rear.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partial enlarged view of the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Example 1: as shown in fig. 1 and 2, the hydraulic tensioner tension pulley with low replacement cost is characterized in that an annular nylon block 2 is arranged on the annular surface of a tension pulley 1, a plurality of annular channels are arranged on the upper surface of the annular nylon block 2, the annular nylon block 2 is formed by splicing a plurality of arc-shaped nylon blocks 3, and the annular nylon block 2 is preferably formed by splicing 8-12 arc-shaped nylon blocks 3; a gap exists at the joint of two adjacent arc-shaped nylon blocks 3, and the gap at the joint of two adjacent arc-shaped nylon blocks 3 is 0.5-1 cm. A plurality of rows of stepped holes 4 which are arranged at equal intervals are arranged on the arc-shaped nylon block 3, 3 rows of the stepped holes 4 are arranged, and 3 are arranged in each row. The annular surface of the tension pulley 1 is provided with a waist-shaped hole 5 matched with the stepped hole 4, the length direction of the waist-shaped hole 5 is consistent with the direction of the annular channel, and a screw 6 passes through the stepped hole 4 and the waist-shaped hole 5 and is screwed through a screw cap 7 to fix the arc-shaped nylon block 3 and the tension pulley 1.
The described embodiments are only some, but not all embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
