Abstract

The utility model relates to a manpower vehicle, which is suitable for carrying out optical cable laying particularly for carrying out emergent optical cable laying in optical cable construction. The utility model comprises a movable vehicle frame and a rear leg frame, wherein both sides at the lower end of the front part of the movable vehicle frame are provided with wheels, and the middle part at the upper part is provided with a half tile bearing assembly which can be opened and closed; the back upper part of the movable vehicle frame is connected with a vehicle handlebar; the lower side at the back part of the movable vehicle frame is hinged with the rear leg frame and is provided with a locking device; both sides at the lower end of the rear leg frame are provided with wheels, so that an optical cable laying truck pushed by man power is formed and the vehicle frame of the optical cable laying truck can be lifted and locked. The utility model has the advantages that the structure of the cable laying truck is compacted, after a cable disc is arranged, the cable laying truck can shift, cable laying is very convenient, and the efficiency of cable laying is high; the assembly and disassembly of the cable disc is labor-saving and quick, and can be quickly realized without using other tools or devices; the arrangement of the half tile bearing assembly can cause the tension for the optical cable releasing wire to be uniform, the quality of construction can be increased and construction operation is more convenient.

Description

The optical cable laying car

Technical field

The utility model relates to and a kind ofly is suitable for carrying out optical cable laying in optical cable construction, especially carries out the rickshaw that relief cable lays.

Background technology

In the fiber cable laying construction, laying normally like this of optical cable: in the center pit of reel, install a metal tube, by manpower or hanging device the two ends of metal tube are set aside to fixedly on the shelf then, the built on stilts also energy of reel freely be rotated, discharge the optical cable of winding on reel with this, finish laying and laying of optical cable.Not only the displacement of reel is very not nimble to adopt this mode, cabling efficient is low, be unfavorable for that more the emergent of optical cable lays, and the last undercarriage of band cable reel extremely bothers, also there is the problem that tension force is inhomogeneous, the reel rotation is nimble inadequately during cable laying, increased the difficulty in the fiber cable laying construction.

Summary of the invention

Technical problem to be solved in the utility model is not enough at above-mentioned existing in prior technology and optical cable laying car that provide a kind of available manpower to carry out, not only the displacement of the laying of optical cable, cable dish is very nimble for it, and undercarriage is convenient on the cable dish, cabling efficient height.

The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: it includes movable carriage 1 and back leg 4, the front lower ends both sides of movable carriage are installed on wheel 3, but the half-watt bearing assembly 5 of upper center setting folding, the back upper place of movable carriage connects handlebar 12, at hinged back leg 4 of the rear portion of movable carriage downside and configuration locking device 9, the both sides, lower end of back leg are installed on wheel.The manpower that constitutes a vehicle frame liftable locking is thus carried out the optical cable laying car.

Press such scheme, be provided with cable dish locking device 7, in order to the rotation or the locking cable dish of control cable dish in movable carriage one side; The configuration pin touches on the brake 6 on the described wheel.

Use of the present utility model is: will lay the anterior perk of car and be inserted in (light) cable dish the cable dish is among the movable carriage, unclamping locking device descends movable carriage, simultaneously pack into the center pit of cable dish both sides of bolster, by promoting handlebar movable carriage is upwards mentioned, with the pinning of closing behind the half-watt bearing assembly of opening of packing into of the bolster of cable dish both sides, carry handlebar in the continuation, empty movable carriage simultaneously of cable plate rail and back leg are closed up put in place, promptly finish the process of putting on the shelf of cable dish with the locking device locking.At this moment, on the one hand by carrying out laying car the cable dish is shifted easily, arrives the construction station, Jia Kong cable dish can rotate flexibly on the other hand, makes the optical cable energy light release of winding on it finish laying and laying of optical cable.

The beneficial effects of the utility model are: 1, cloth cable car structure compact, load onto cable dish backward shift, the cloth cable is very nimble, and cabling efficient height can adapt to the working-yard of various complexity, is particularly suited for promptly laying of optical cable; When 2, reel lifts, utilize the lever principle of movable carriage front-wheel fulcrum, laborsaving convenient, can not realize loading and unloading fast by other instrument and device; 3, the half-watt bearing assembly is arranged so that optical cable laying tension uniform and stable, improved the quality of construction, when optical cable does not lay, by adjusting cable dish locking device, reel is by locked, can prevent that carrying out the rotation of shifting process mid-game tool at the cloth cable car causes the optical cable winding displacement lax, makes constructing operation more convenient.

Embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.Include movable carriage 1 and back leg 4, movable carriage connects cross bar 11 by monosymmetric triangular framing at the anterior angle place and constitutes, the front lower ends both sides of movable carriage are installed on wheel 3 by wheel seat 10, the upper center of movable carriage (drift angle place) but the half-watt bearing assembly 5 of folding is set, described half-watt bearing assembly comprises,

step

17,15, on, but step folding and locking, on, install bolster in the step, bolster comprises spindle nose 20, two bearings 19 are installed with last in the spindle nose rear portion, the step phase configuration, lock at interval and by spring collar 16 by axle sleeve 18 between the two bearings, be provided with crank joint 14 in the rear end of bolster, the movable crank 8 of suit on the crank joint, in addition, also be installed with cable dish fixed claw 13 in the front portion of bolster, constitute the half-watt bearing assembly thus; Wherein the front end of bolster is used to support the cable center hole, and cable dish fixed claw and cable dish 2 side openings match, and the rotating speed by movable crank may command cable dish is used for the artificial unwrapping wire and the take-up of optical cable; The back upper place of movable carriage connects handlebar 12, and at hinged back leg 4 of the rear portion of movable carriage downside and configuration locking device 9, locking device can be made up of cutting ferrule and bolt, and the both sides, lower end of back leg are installed on wheel by wheel seat 10; The manpower that constitutes a vehicle frame liftable locking is thus carried out the optical cable laying car.In addition, be provided with cable dish locking device 7 in movable carriage rear portion one side, cable dish locking device is made of screw rod and the termination friction block that band revolves handle, with rotation or the locking of cable dish card configuration in order to control cable dish; Also configurable pin touches on the brake 6 on wheel, carries out the braking and the location of car.
