Abstract

The invention provides a pulley with an anti-freezing function, which comprises a pulley main body, wherein a pulley groove is arranged on the outer circumferential surface of the pulley main body, and the pulley is characterized in that: the hollow pins are distributed in the pulley grooves, and the rope is in contact with the hollow pins during operation. The invention has the advantages that: the phenomenon that the rope is frozen is improved, the consumption of the rope is reduced, and meanwhile, the pulley has universality with a common pulley.

Description

A kind of pulley with antifreeze function
Technical field
The present invention relates to a kind of pulley with antifreeze function, cable is not freezed in the time of can realizing the severe cold area construction, belong to the subterranean continuous wall hydraulic grab technical field.
Background technology
When subterranean continuous wall hydraulic grab is constructed at severe cold area, grab bucket steel rope, oil pipe, the subsidiary mud of cable in the process that promotes can freeze rapidly, each cable can freeze together with pulley by crown sheave the time, and the cable that the wire of cable inside or other tensile strength are less can rupture because pullling.At present, in the industry pulley is freezed phenomenon and also do not have desirable solution.
Summary of the invention
The purpose of this invention is to provide a kind of pulley with antifreeze function, improve the frozen phenomenon of cable in the situation that do not increase other additional device.
In order to achieve the above object, technical scheme of the present invention has provided a kind of pulley with antifreeze function, comprise pulley main body, outer circumference surface place at pulley main body is provided with pulley groove, it is characterized in that: in pulley groove, be distributed with the hollow out pin, when being operated in antifreeze state, cable contacts with the hollow out pin.
The contact surface of the present invention by reducing cable and pulley groove (contacted change Multi-contact into by face), thus greatly reduced the face of freezing.
Advantage of the present invention is: improved the frozen phenomenon of cable, reduced the consumption of cable, had again commonality with common pulley simultaneously.
Description of drawings
Fig. 1 is a kind of pulley schematic perspective view with antifreeze function provided by the invention;
Fig. 2 is a kind of pulley assembling schematic diagram with antifreeze function provided by the invention.
The specific embodiment
Specify the present invention below in conjunction with embodiment.
Embodiment
As shown in Figures 1 and 2, for a kind of pulley with antifreeze function provided by the invention, formed by pulley main body 1, hollow out pin 2 and spring cotter 3.Be evenly equipped with the hollow out pin 2 of some in the pulley groove of pulley main body 1, hollow out pin 2 links to each other with pulley main body 1 with interference fit.End at each hollow out pin 2 is inserted with a spring cotter 3, is used for preventing the vibration of hollow out pin 2.
When cable rolled at the pulley with antifreeze function provided by the invention, contact surface became hollow out pin 2(by pulley groove and namely becomes Multi-contact by the face contact).The structure of hollow out is conducive to the drainage of mud simultaneously, freezes phenomenon and is greatly improved.And the pulley main body 1 of removal hollow out pin 2 and spring cotter 3 rear antifreeze functions can use as common pulley.

Claims (3)

1. the pulley with antifreeze function comprises pulley main body (1), is provided with pulley groove at the outer circumference surface place of pulley main body (1), it is characterized in that: be distributed with hollow out pin (2) in pulley groove, during work, cable contacts with hollow out pin (2).
2. a kind of pulley with antifreeze function as claimed in claim 1 is characterized in that, described hollow out pin (2) links to each other with described pulley main body (1) with interference fit.
