Abstract
The utility model provides a pulley with antifreezing function, which comprises a pulley body, and the outer circumference surface of the pulley body is provided with a pulley groove. The pulley of the utility model is characterized in that hollowed pins are distributed in the pulley groove, and a rope is in contact with the hollowed pins while in work. The utility model has the advantages of improving the phenomenon of rope freezing and reducing the consumption of the rope; meanwhile, the utility model has generality with a common pulley.
Description
Technical field
The utility model relates to a kind of pulley with antifreeze function, cable is not freezed in the time of can realizing the severe cold area construction, belongs to the subterranean continuous wall hydraulic grab technical field.
Background technique
When subterranean continuous wall hydraulic grab is constructed at severe cold area, grab bucket wire 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 less cable of the lead of cable inside or other tensile strength can rupture because of 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 utility model provides a kind of pulley with antifreeze function, improves the frozen phenomenon of cable under the situation that does not increase other additional device.
In order to achieve the above object, the technical solution of the utility model has provided a kind of pulley with antifreeze function, comprise pulley main body, outer peripheral 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.
Further, being inserted with cotter pin in described hollow out pin moves with the string that prevents the hollow out pin.
The surface of contact of the utility model by reducing cable and pulley groove (contact change the multiple spot contact into by face), thus significantly reduced the face of freezing.
The utility model has the advantages that: improved the frozen phenomenon of cable, reduced the consumption of cable, had versatility again with common pulley simultaneously.
Description of drawings
A kind of pulley schematic perspective view that Fig. 1 provides for the utility model with antifreeze function;
A kind of pulley assembling schematic representation that Fig. 2 provides for the utility model with antifreeze function.
Embodiment
Specify the utility model below in conjunction with embodiment.
As shown in Figures 1 and 2, for a kind of pulley that the utility model provides, form by pulley main body 1, hollow out pin 2 and cotter pin 3 with antifreeze function.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 cotter pin 3, is used to prevent that the string of hollow out pin 2 is moving.
When cable rolled on the pulley with antifreeze function that the utility model provides, surface of contact became hollow out pin 2(promptly by the contact of face contact becoming multiple spot by pulley groove).The structure of hollow out helps the drainage of mud simultaneously, freezes phenomenon and is greatly improved.And the pulley main body 1 of removal hollow out pin 2 and cotter pin 3 back 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 peripheral 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.
3. a kind of pulley with antifreeze function as claimed in claim 1 or 2 is characterized in that, is inserted with cotter pin (3) and moves with the string that prevents hollow out pin (2) in described hollow out pin (2).
