Abstract
The utility model relates to the technical field of pile machines, in particular to an anti-loosening device for a wire rope pulley. The anti-loosening device comprises a pulley bracket and a pulley. The anti-loosening device is characterized by comprising an anti-loosening ring and a positioning plate, wherein the anti-loosening ring comprises semi-round ring bodies, a transverse stopper and a fixed plate; the two semi-round ring bodies are fixedly connected with each other by the transverse stopper; the width of the anti-loosening ring corresponds to the width of a pulley slot; the fixed plate is arranged at the external side of the anti-loosening ring; the positioning plate is fixed on the pulley bracket; the two anti-loosening rings cover the external edge of the pulley respectively; and two sides of the anti-loosening rings can be used for fixing the fixed plate on the positioning plate by bolts so that the wire rope can not separate from the pulley slot when moving in the pulley slot owning to the blocking of the anti-loosening ring at the external edge of the pulley. By adopting the structure, the anti-loosening device has the advantages of novel structure, hard to separate, long service life, convenience in disassembly and assembly, convenience in maintenance, and the like.
Description
Technical field
The utility model relates to a machine technology field, specifically a kind of chain wheel rope anti-drop device that is used for a machine.
Background technology
At present, the wire rope pulley anti-drop device of existing pile driver is by pulley bracket, pulley, wire rope and baffle plate are formed, pulley and pulley bracket are hinged, the outer rim of pulley is provided with baffle plate, to prevent that wire rope breaks away from from pulley groove, baffle plate is fixedlyed connected with pulley bracket, wire rope is walked around pulley groove one end and is connected with framework on the pile driver, the other end is wound on the reel, by drive unit wire rope is slided in pulley groove, rise or descend with the rig that drives on the framework, in the motion process of wire rope, torsion appears in wire rope easily, therefore, bore or stop to carry the stagnation moment of brill under rig stops, wire rope is lax easily under the effect of torsion, wire rope after lax then breaks away from from the slit at the edge of pulley groove and baffle plate, perhaps be stuck in the slit between pulley groove and the baffle plate, wire rope is short application life, and maintenance is inconvenient, brought potential safety hazard to production simultaneously.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, a kind of novel structure is provided, is difficult for slippage, long service life, easy accessibility, wire rope pulley anti-drop device easy to maintenance.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of wire rope pulley anti-drop device, comprise pulley bracket and pulley, it is characterized in that being provided with anti-decylization and location-plate, anti-decylization comprises semicircle ring body, crosspiece and fixed head, fixedly connected between two semicircle ring bodies through crosspiece, the width of anti-decylization conforms to the width of pulley groove, the outside of anti-decylization is provided with fixed head, location-plate is fixed on the pulley bracket, two anti-decylizations cover on the outer rim of pulley respectively, both sides are fixed on fixed head on the location-plate through bolt, make wire rope in pulley groove when mobile through the stopping of the anti-decylization of pulley outer rim, can not break away from pulley groove.
The semicircle ring body in the utility model and the section of crosspiece are rounded respectively, reach the effect that is difficult for the scratch wire rope.
The inboard of the crosspiece in the utility model be provided with
Wire ropeThe arc that matches makes wire rope be difficult for breaking away from pulley
Distortion
The utility model is owing to adopt said structure, has novel structure, is difficult for slippage, long service life, easy accessibility, advantage such as easy to maintenance.

Reference numeral: pulley bracket 1, pulley 2, anti-decylization 3, location-plate 4, semicircle ring body 5, crosspiece 6, fixed head 7, bolt 8, wire rope 9.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in drawings, a kind of wire rope pulley anti-drop device, comprise pulley bracket 1 and pulley 2, it is characterized in that being provided with anti-decylization 3 and location-plate 4, anti-decylization 3 comprises semicircle ring body 5, crosspiece 6 and fixed head 7, fixedly connected between two semicircle ring bodies 5 through crosspiece 6, the width of anti-decylization 3 conforms to the groove width of pulley 2, anti-decylization 3 outsides are provided with fixed head 7, location-plate 4 is fixed on the pulley bracket 1, and two anti-decylizations 3 cover on the outer rim of pulley 2 respectively, and both sides are fixed on fixed head 7 on the location-plate 4 through bolt 8, make wire rope 9 in pulley groove when mobile through the stopping of the anti-decylization 3 of pulley 2 outer rims, can not break away from pulley groove.
The semicircle ring body 5 in the utility model and the section of crosspiece 6 are rounded respectively, reach the effect that is difficult for the scratch wire rope.
The inboard of the crosspiece 6 in the utility model is provided with the arc that matches with wire rope 9, make wire rope 9 be difficult for breaking away from pulleys and
Distortion
In use, can be on bolt 8 be fixed on location-plate 4 on the pulley bracket 1 with the fixed head 7 at two anti-decylization 3 two ends, make anti-decylization 3 corresponding pulley groove outer rims form a shaped form gap, wire rope 9 is difficult to form the curve consistent with this gap parameter, and from this gap, deviate from, therefore, wire rope 9 is all the time in the sealing frame of two semicircle ring bodies and crosspiece 6 formations, after anti-decylization 3 and pulley 2 relative positions fix, wire rope 9 is moved in the annular space of pulley groove and 3 formation of anti-decylization, contacting between wire rope 9 and the anti-decylization 3 is a contact, the very difficult damage of wire rope 9, be the arc contact with contacting of crosspiece 6 perhaps, wire rope 9 is not yielding, long service life.
The utility model is owing to adopt said structure, has novel structure, is difficult for slippage, long service life, easy accessibility, the advantage such as easy to maintenance.
