Description

A kind of hydraulic pressure fixing-line device

Technical field

The utility model relates to a kind of stringing instrument, is used for power system, and it relates to a kind of hydraulic pressure fixing-line device.

Background technology

Fixing-line device is the Line tool of holding of commonly using in electric power, telecommunications, railway electrification overhead line construction and maintenance. but existing fixing-line device is all to pass through ratchet, the simple and mechanical realization such as screw rod is fixed, the Chinese patent that fixing-line device of the prior art is 2015100613414 as application number is open, two operating members and a connecting rod, by movable end thread jamming part and stiff end thread jamming part, thread like body is realized to clamping, one mode due to this clamping, be 2 extruding fixed forms, fixed effect is poor, easily wearing and tearing thread like body, two because method of clamping is comparatively complicated, particularly in the time loosening thread like body, because the moment of needs exerts all one's strength larger, so easily workmen is caused to potential safety hazard.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of simple to operate and preferably fixing-line device of locking effect.

For achieving the above object, the utility model provides following technical scheme: a kind of hydraulic pressure fixing-line device, the retaining collar that comprises housing and set firmly with housing, described enclosure interior is provided with anchor device structure, described anchor device structure comprises the anchor ring being wholely set with housing, and described anchor ring is equipped with Taper Pipe, and one end butt of described Taper Pipe is extruded assembly, its other end butt has hydraulic package, and described hydraulic package at least comprises a hydraulic stem and a pressure-relief valve; When pressure-relief valve is opened, described in extrude assembly and provide the power of extruding so that Taper Pipe locking thread like body for described Taper Pipe; Pressure-relief valve when cut-off, can be by operation hydraulic stem that Taper Pipe provides hydraulic coupling so that Taper Pipe unclamps thread like body.

Need to use time, first, by hydraulic package, by hydraulic coupling, Taper Pipe is taken in to enclosure interior, wear the relation of cooperation due to Taper Pipe and anchor ring simultaneously, because hydraulic coupling is larger, so just Taper Pipe can be loosened by hydraulic stem, make the aperture of Taper Pipe become large simultaneously, now penetrate and want fastening line body, and after thread like body puts into, just can be by loosening pressure-relief valve, now because hydraulic pressure disappears, so the power of extruding that extruding assembly provides can make Taper Pipe tighten up, locking thread like body. Arrange like this, simple to operate reasonable, the while one, provide action force by the mode of hydraulic pressure, operation is convenient, two realize locking by Taper Pipe, and when locking, the contact area of Taper Pipe and thread like body is larger, can prevent that thread like body from rotating wearing and tearing, the 3rd, just can locking thread like body by pressure-relief valve, simple to operate, be difficult for causing danger.

Further: described in extrude assembly and comprise and extrude sleeve and elastic component, described in extrude sleeve and be connected to provide by elastic component elasticity the power of extruding with housing. By extruding the setting of sleeve and elastic component, the power of extruding can be provided, ensure that again transmission is stable, increase service life.

Further: described in extrude sleeve and described Taper Pipe and coordinate by a guiding surface. Coordinate by guiding surface, make it not be prone to wearing and tearing.

Further: described hydraulic package also comprises a thrust piston, described thrust piston be arranged in enclosure interior and with described Taper Pipe butt. By the setting of thrust piston, ensure the stable of transmission, meanwhile, make Taper Pipe stressed even when mobile.

Further: described thrust piston is provided with the first spacing preiection, described enclosure interior is provided with a chute, and one end that described chute deviates from Taper Pipe is provided with the second spacing preiection. By the setting of the first spacing preiection and the second spacing preiection, can prevent that thrust piston from deviating from from housing.

Further: on described the first spacing preiection and the second spacing preiection, be provided with draw-in groove, described draw-in groove is connected with sealing ring. By the setting of sealing ring and draw-in groove, the stability while having ensured motion, and sealing, increase service life, ensures stable drive.

By adopting technique scheme, one, mode by hydraulic pressure provides action force, and operation is convenient, and two realize locking by Taper Pipe, when locking, the contact area of Taper Pipe and thread like body is larger, can prevent that thread like body from rotating wearing and tearing, the 3rd, just can locking thread like body by pressure-relief valve, simple to operate, be difficult for causing danger.
