Multi-connected cable pulley

Abstract

The invention discloses a multi-connected cable pulley. The multi-connected cable pulley comprises at least two sets of cable pulleys which are matched with each other; the cable pulley comprises mounting plates at two sides and a pulley mounted between the mounting plates; the mounting plates at the two sides are of triangle structures; and the bottom sides of the triangular mounting plates of the two sets of cable pulleys are separately provided with one hinging shaft. According to the multi-connected cable pulley of the invention, the hinging shafts are installed between the two matched cable pulleys; the hinging plates are provided with hinging shafts; clamping grooves are formed in the hinging plate at one side, and a clamping block is arranged on the hinging plate at the other side;the clamping block can be installed in the different clamping grooves, so that an interval between the two cable pulleys can be adjusted; the hinging plates can be installed through the hinging shafts, so that the angle of the multi-connected cable pulley can be changed freely, the length of the multi-connected cable pulley can be adjusted through the clamping grooves and the clamping block, and therefore, the multi-connected cable pulley can be conveniently arranged at the mouth of a well to protect a cable and a traction rope; and the two cable pulley sets can be conveniently disassembled bymeans of the cooperation of the clamping grooves and the clamping block, and therefore, the multi-connected cable pulley is very convenient to carry and mount.

Description

technical field [0001] The invention relates to electric power construction equipment, in particular to a multi-connection cable pulley. Background technique [0002] The multi-connected cable pulley is composed of multiple cable pulleys, and is mostly used to protect the traction rope or cable at the wellhead or the exit. The existing multi-connected cable pulley block is only a combination of multiple cable pulleys. Together, and the mounting plates on both sides are directly installed together, resulting in a very small interval between the two pulleys, so even in some outlets with relatively small diameters, it is necessary to install more pulleys to ensure that the traction rope does not touch the well wall. There are two cable pulley blocks, the interval cannot be adjusted and it will take up a lot of space. Contents of the invention [0003] The object of the present invention is to provide a multi-connection cable pulley to address the deficiencies in the prior ar...
