Abstract

The utility model provides a self-locking cable slide car device. The device comprises a frame. The upper end of the frame is a support steel pipe having a reverse-U-shaped upper part. One side of the support steel pipe is provided with an opening spring, and an opening baffle plate is arranged on the opening spring. The top of the opening baffle plate is connected with one end of a pulling rope, while the other end of the pulling rope passes through the support steel pipe to be connected with a pulling rod. The pulling rod is arranged on a puller. A pull-down spring is arranged at the lower part of the pulling rod. According to the self-locking cable slide car device provided the utility model, the support steel pipe at the upper end of the frame is designed to be reverse-U-shaped, the spring is arranged at the opening to connect the baffle plate and the support steel pipe, the pulling rope connected with the pulling rod is arranged above the opening baffle plate, the pulling rod is arranged on the puller, the pulling rod passes through the puller and provided with the pull-down spring at the lower part, so that if the puller is not pulled upwardly, the opening baffle is closed, ensuring the operation safety of the slide car on the cable. The self-locking cable slide car device is simple in structure and convenient in operation, being valuable for popularization and application.

Description

A kind of self-sealing hanging wire runaway device
Technical field
The utility model belongs to transmission line construction technical field, is specifically related to a kind of self-sealing hanging wire runaway device.
Background technology
In power line construction and maintenance repair activity, hanging wire driving is widely used in leads on-line operation, staff enters before driving along rope ladder, or jump out hanging wire driving along rope ladder in surface process, the sealing pin of hanging wire driving all will be opened, hanging wire driving mouth hanging cannot carry out locking with regard to realizing after climbing up staff, can only be after equal potential working personnel put in place could locking, and operating personnel follows the line of least resistance sometimes, there will be not locking after ladder, when descending stair, can occur because of general idea the situation of not unblanking, this has also formed hidden danger to safety.Staff is constituted a threat to safely.A kind of releasing pulley with auto-lock function is disclosed in CN 201774184 U, flap is connected with respectively eccentric wheel and main wheel by axle up and down, main wheel is connected with gear, gear is connected with eccentric wheel by pull bar, between eccentric wheel and main wheel, leave gap, flap upper end is connected with hook, and flap one side is provided with hinge.The utlity model has auto-lock function, more convenient safety during use.Yet it is when being applied in hanging wire driving, and it is very inconvenient to use, be unfavorable for hanging and removing, so need a kind of self-sealing hanging wire runaway device simple in structure, easy and simple to handle.
Utility model content
The utility model provides a kind of self-sealing hanging wire runaway device simple in structure, easy and simple to handle.
The technical scheme that adopted to achieve these goals: a kind of self-sealing hanging wire runaway device, comprise framework, described framework upper end is supporting steel pipe, described supporting steel pipe top is inverted U, described supporting steel pipe one side arranges split ring, on described split ring, open closure is set, described open closure top is connected with rope one end, the other end of described rope is connected with lifting rod through after supporting steel pipe, described lifting rod is arranged on drawing device, and described lifting rod bottom arranges drop-down spring.
Described lifting rod upper end arranges and lifts hole.
Described rope is arranged in protective sleeve.
Described protective sleeve is fixed by fixed card.
Described drop-down spring is disk spring.
Described rope is insulating cord.
Described open closure is steel piece.
Described drawing device is that centre is circular hole.
The utility model is designed to inverted U by the supporting steel pipe of the upper end of framework, and at opening part, open closure is set, and open closure is connected with supporting steel pipe by split ring, rope is set above open closure, the other end of rope is connected with lifting rod after protective sleeve through passing through after supporting steel pipe, lifting rod is arranged on drawing device, drawing device is annular through-hole, lifting rod is arranging drop-down spring through after drawing device in bottom, make in the situation that drawing device does not upwards lift, under acting in conjunction due to drop-down spring and split ring, make open closure closed, guaranteed safety when driving is worked on cable, while operating at the scene, staff first mounts insulated flexible ladder in this driving below, by pre-packed lifting slide block, insulating cord fag end is passed to behind ground, insulating cord fag end is penetrated to lifting hole and tying up of this driving lifting rod top, pull other one end insulating cord fag end, hanging wire driving is slowly pulled to eminence, inverted U at supporting steel pipe exceeds wire level height, is hung on wire, after hanging on wire, unclamp insulating cord, because rope ladder, the gravity of driving itself are contrary with the pulling force of insulating cord, under the acting in conjunction of drop-down spring, lifting rod self gravitation and split ring, make open closure realize self-locking, then the ascending stair that personnel can be safe operates.In lower ladder, step order is contrary with above-mentioned steps.The utility model is simple in structure, easy and simple to handle, under equal resources supplIes, has brought into play to greatest extent its use value, is worthy to be popularized and applies.
