Description

A kind of power transmission lines overhauling driving

The application is application number is 2012103777605, and the applying date is on October 8th, 2012, and denomination of invention is a kind of divisional application of power transmission lines overhauling driving.

Technical field

The present invention relates to high voltage line maintenance equipment technical field, refer to a kind of power transmission lines overhauling driving especially.

Background technology

Transmission line especially high voltage power transmission and transforming circuit is all high-altitude erection, when overhauling it, needs to utilize driving to carry out outlet operation.It is rely on the drop of wire suspension generation to coordinate manually to catch wire to pull that existing maintenance driving needs to advance simultaneously, driving braking is then grab wire oppositely firmly to stop driving with artificial hand, the speed being all difficult to control driving when driving is advanced or when braking driving, simultaneously, exposed driving pulley is also easy to overwhelm hand, for this reason, there is the tight lock set of brake having related to driving in the Double-bundled-conductor racing vehicle of application number for use in a kind of transformer station disclosed in the Chinese patent of 200920209782.4, this modular construction is complicated, also hand cannot be overwhelmed by anti-limited slip wheel.Also have that application number is four disclosed in the Chinese patent of 201120152908.6, the dual-purpose driving of six-multiple conductor, it relate to a kind of foot-operated braking scheme, but the program has requirement to driving itself, driving is needed to carry a work chamber, then foot-operated brake apparatus is installed in work chamber, so this braking scheme scope of application is limited.

Summary of the invention

For solving the problem, the invention provides a kind of power transmission lines overhauling driving, it is simple that this driving has structure, and brake apparatus applied widely, when this brake apparatus can prevent driving from sliding simultaneously, pulley is pressed onto maintainer on hand.

Technical scheme of the present invention is as follows: a kind of power transmission lines overhauling driving; comprise the vehicle frame be made up of interconnective two pillars; two pillars are respectively provided with a pulley; described pulley is provided with brake apparatus; described brake apparatus comprises the protective cover covered on pulley; form extension in the bottom end horizontal expansion of described protective cover, below described extension, be provided with brake(-holder) block.Maintenance driving is in sliding process, and pulley can slide along wire, presses down extension, be then positioned at brake(-holder) block below extension and wire and rub and just can brake driving.Owing to there being protective cover to be covered by pulley, so pulley is when near maintainer's hand, will block by protected cover, anti-limited slip wheel overwhelms on hand.

As a further improvement on the present invention and optimize, following measure can be taked:

Two described pillars are respectively provided with a framework, and be equipped with a rotating shaft in framework, rotating shaft is provided with pulley.

Described protective cover includes the support chip be positioned at above described pulley; catch and rear catch before the two ends of support chip are provided with; described front catch and rear catch cover on the both sides, front and back of pulley respectively; described front catch bottom horizontal expansion forms extension; brake(-holder) block is provided with below described extension; described rear catch is provided with fixed strip, and described fixed strip is fixed on described framework.

Described fixed strip has two lay respectively at the left and right sides of described pulley and be fixed on described framework.Protective cover can more firmly be fixed on described framework by the fixed strip of pulley bilateral.

Described support chip is fixed on described framework, can stablize the connection between protective cover and framework, avoids protective cover to rock when driving slides.

Described front catch is provided with the brake(-holder) block stretching to pulley.Brake(-holder) block on front catch, when being pressed towards pulley, producing with pulley and rubs, can brake driving equally.

Connect a connecting rod between described front catch and rear catch, one end of connecting rod is fixed on rear catch, and the other end of connecting rod passes front catch and is slidably connected.Connecting rod can keep the shape of protective cover, prevents it from staying.

Described connecting rod is set with a Compress Spring, one end of described Compress Spring is fixed on connecting rod, and the other end is against on front catch.Under the effect of Compress Spring, the front catch be pressed down is easy to resilience.

The material of described protective cover is steel.Employing steel are that the protective cover of material possesses enough intensity and elasticity.

Compared with prior art, outstanding advantages of the present invention is: adopt the protective cover installing band brake sheet on driving pulley additional, not only can play the effect of braking driving, and can be pressed onto the hand of maintainer when sliding by anti-limited slip wheel; Structure of the present invention is simple, operates simple and easy, with low cost, goes for the maintenance driving of all band pulleys.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Fig. 1 is structural representation of the present invention;

Fig. 2 is the structural representation at pulley place of the present invention;

Fig. 3 is the structure cutaway view of protective cover of the present invention.

Embodiment

See Fig. 1 and Fig. 2, a kind of power transmission lines overhauling driving, comprises the vehicle frame be made up of interconnective two pillars 1, and two described pillars 1 are respectively provided with a framework 4, are equipped with a rotating shaft 41 in framework 4, rotating shaft is provided with described pulley 2.Described pulley is provided with brake apparatus, and described brake apparatus comprises the protective cover 3 covered on pulley 2, forms extension 31, be provided with brake(-holder) block 32 below described extension 31 in the bottom end horizontal expansion of described protective cover 3.When pressing down protective cover extension 31, brake(-holder) block 32 and wire friction catch driving.For protective cover tool 3 prepares enough enough intensity and elasticity, the material of described protective cover 3 is steel.
