Abstract
The utility model relates to an unpowered coaster, which is hung on two guide lines and comprises a trailer and pulley groups, wherein the pulley groups are arranged at both sides of the trailer, the distance between the pulley groups arranged at both sides of the trailer is the same as the distance between the two guide lines for hanging the unpowered coaster, each pulley group comprises a pulley and a pulley shaft, the pulley is fixed on the trailer through the pulley shaft and can rotate around the pulley shaft, and the outer periphery of the pulley is provided with grooves for embedding the guide lines. The coaster is not provided with a motive power source and moves on the construction guide lines through the pushing force of construction personnel, the structure of the coaster is simplified, and the size and the self weight of the coaster can also be decreased.
Description
[technical field]
The utility model relates to the construction of power transmission and transformation field, relates in particular to the unpowered driving that uses in a kind of construction of power transmission and transformation.
[background technology]
In the voltage levels circuit send electricity construction, after setting up and finish, cable often needs manually to line, to go the accessory equipment of installation interval rod, stockbridge damper and so on.In landform areas with complicated comparatively, for example line is the gully or the place in pool down, and instrument that the workman need use and utensil can only be carried.Because these object weight are heavier, the workmen is operation aloft in addition, and is very inconvenient, therefore designs a kind ofly can load the little driving that a certain amount of Work tool can easily move again on line actual value is arranged very much.
For solving the problem that workman's aloft work is not easy to the instrument that carries and utensil, dynamic driving has appearred in the aloft work.Dynamic driving adopts diesel engine to make prime power usually, perhaps adopts the chain-driving mode of bicycle type.Yet this dynamic driving is because of the external propulsion source of needs, so the structure more complicated.If required instrument that carries of aloft work and utensil are also few, it is not very necessary adopting this dynamic driving.
Therefore, designing a kind of driving that transports high-altitude operations tool and utensil simple in structure extremely is necessary.
[utility model content]
In view of this, the utility model provides a kind of unpowered driving simple in structure.
A kind of unpowered driving, described unpowered driving are suspended on two leads and comprise trailer and assembly pulley.Described assembly pulley is arranged on the both sides of described trailer, the distance that is arranged between the described assembly pulley of both sides of described trailer equates with distance between two leads that hang described unpowered driving, described assembly pulley comprises pulley and sheave shaft, described pulley is fixed on the described trailer by described sheave shaft and can rotates around described sheave shaft, and the periphery of described pulley is provided with can be for the groove of lead embedding.
Preferably, the outer wall of described trailer is provided with the hook that can hang Work tool.
Preferably, described unpowered driving also is provided with the self-locking device of the described assembly pulley of braking, and described self-locking device is arranged on the sidewall of described trailer, and described self-locking device has the brake facing of the pulley of the described assembly pulley of braking.
Preferably, described self-locking device also comprises screw mandrel, and described screw mandrel one end connects described brake facing, and the other end is connected with and drives described screw mandrel and brake facing movable handle.
Preferably, described self-locking device comprises that also spiral shell is fixed and adapter plate, and described spiral shell fixedly is screwed on outside the described screw mandrel and is fixed on the adapter plate, and described adapter plate is fixed on the sidewall of described trailer.
Driving of the present utility model is not provided with propulsion source, relies on workmen's propelling thrust to move on construction wire, not only can simplify the structure of driving, can reduce the volume and the deadweight of driving yet.

Fig. 1 is the cross section structure scheme drawing of the unpowered driving of preferred embodiment of the present utility model.
Fig. 2 is the construction profile scheme drawing of the unpowered driving among Fig. 1.
Fig. 3 is the brake shoes of the self-locking device among Fig. 2 and the relative structural representation of pulley.
[specific embodiment]
In order to understand the utility model better, be described in detail below with reference to instantiation and accompanying drawing embodiment to utility model.
For simplifying the structure of driving, the utility model provides a kind of unpowered driving, and its preferred embodiment is as shown in figure to Fig. 3.This unpowered driving comprises trailer 10, assembly pulley 20 and self-locking device 30.
The upper shed formula casing means of delivery that trailer 10 is made for aluminum alloy, its inside can carry and hold workmen and shipment instrument or material.The width of trailer 10 is about the distance between two leads, can slide on aerial line, installs and keeps in repair with convenient workmen.Hook 12 can be set on the outer wall of trailer 10, be used to hang larger-size Work tool.
Self-locking device 30 be arranged on assembly pulley 20 directly over, be used for after trailer 10 moves to a certain place the position of locking trailer 10.Please in conjunction with consulting Fig. 2 and Fig. 3, self-locking device 30 comprises that brake shoes 32, screw mandrel 34, adapter plate 36, spiral shell fix 38 and handle 39.Brake shoes 32 is arranged on the top of cooresponding pulley 22, and the lower edge of brake shoes 32 is curved, can embed in the groove of pulley 22, with pulley 22 friction to take place it is stopped operating.The top of brake shoes 32 is connected with screw mandrel 34, is with the spiral shell that is fixed on the adapter plate 36 outside the screw mandrel 34 and fixes 38.Adapter plate 36 is fixed on the top of trailer 10.The top of screw mandrel 34 is connected with handle 39.Turning handle 39 can make brake shoes 32 descending, pushes down pulley 22 and makes it and can not rotate, and has realized that promptly the self-locking of trailer 10 is stopped.Instead twist handle 39 when needing motion, brake shoes 32 up unclamping, pulley 22 can freely rotate.
It is casing that above-mentioned unpowered driving adopts aluminum alloy trailer 10, the trailer 10 outer hooks 12 that hang Work tool that are provided with, and the workmen can easily promote driving and move on lead, is convenient to construction.Self-locking device 30 is installed on the driving, after the workmen is transported to attachment point with Work tool, can starts self-locking device 30, driving will be fixed on line and not move, and make things convenient for the workman to construct, and open handle 39 when needs are mobile, get final product easy movement.
Dynamic driving build is bigger, and is heavier again, and aloft construction is inconvenient.Compare with dynamic driving, above-mentioned unpowered driving have volume little, from the characteristics of heavy and light.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
