Abstract

The utility model provides a novel somersault coaster, it includes the couple, locates the rings of couple upper end, locates the fixed pulley and the blocking device that get in touch the lower extreme, blocking device include one section curved from the locking lever, be fixed with branch on couple division actinal inner wall, middle part from the locking lever hinges on the branch, in an initial state, from locking lever suspension under self action of gravity, from the upper end of locking lever distance there is the interval between the inboard of couple, from the lower extreme of locking lever with the couple forms the cable entry, under the lock -out state, shifted up to the butt by the cable oppression from the upper end of locking lever the couple is inboard, make from the inside perk of the lower extreme of locking lever cable entry interval reduces. This novel somersault coaster has the design science, the locking is convenient, the security is high, simple structure's advantage.

Description

Novel somersault coaster

Technical field

The utility model relates to a kind of coaster, specifically, relate to a kind of novel somersault coaster.

Background technology

In power industry, for reducing interruption duration, ensureing power supply reliability, often needing to carry out uninterrupted operation, i.e. live line working.Current live line working mainly contains three kinds of modes: earth potential working, equal potential working, medial potential working.Wherein equal potential working is owing to directly can carry out the work that operation can solve more complicated by contact electrification body, is a kind of operational method that each power supply unit is relatively more conventional.And to adopt rope ladder method to enter electric field in equal potential working be a kind of the most frequently used method.During concrete use, somersault coaster hangs on wire by equipotential personnel, and rope ladder is pulled near wire by somersault coaster by equipotential personnel, is then suspended from wire by rope ladder.Somersault coaster used at present scarcely has locking device, is easy to occur that coaster departs from the situation of wire, causes occurring falling object from high altitude accident in lift rope ladder process.

In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, thus a kind of design science is provided, locking is convenient, fail safe is high, the simple novel somersault coaster of structure.

To achieve these goals, the technical scheme that the utility model adopts is: a kind of novel somersault coaster, comprise hook, be located at the suspension ring of hook upper end, be located at the fixed pulley and locking device of linking up with lower end, described locking device comprises the self-lock rod of one section of arc, the inwall of described hooking slits side is fixed with pole, and the middle part of described self-lock rod is hinged on described pole;

Under initial condition, described self-lock rod suspends under self gravitation effect, and the upper end of described self-lock rod exists spacing between the inner side apart from described hook, and lower end and described hook of described self-lock rod form cable entries;

Under lock-out state, the upper end of described self-lock rod abuts described hook inner side by cable compressing moves to, and the lower end of described self-lock rod inwardly tilts and described cable entries spacing is reduced.

Described on base, perforation is offered in the side in the middle part of described self-lock rod, and the upper correspondence of described pole is provided with straight pin.

The utility model hinge structure has substantive distinguishing features and progress, specifically, the utility model adopts lever principle to arrange self-lock rod, self-lock rod can be swung up and down, under initial condition, not by External Force Acting, self-lock rod suspends under oneself state, opening is larger, can ensure that cable is more prone to pass through, this somersault coaster is hung over after on cable, self-lock rod upper end pressurized, close to hook inner side, until abut described hook inner side, and self-lock rod lower end inwardly tilts under the effect of lever principle, openings get smaller, cable is not easily deviate from, ensure that the fail safe of somersault coaster.

Further, hinged end adopts the form of perforation and straight pin to arrange, more stable.

It has design science, locking is convenient, fail safe is high, the simple advantage of structure.

Accompanying drawing explanation

Fig. 1 is the structural representation in the utility model under novel somersault coaster initial condition.

Fig. 2 is the structural representation in the utility model under novel somersault coaster blocking.

In figure: 1. link up with; 2. suspension ring; 3. fixed pulley; 4. self-lock rod; 5. upper end; 6. lower end; 7. pole; 8. opening; 9. cable.

Embodiment

Below by embodiment, the technical solution of the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of novel somersault coaster, comprise hook 1, be located at the suspension ring 2 of hook 1 upper end, the fixed pulley 3 being located at hook 1 lower end and locking device, described locking device comprises the self-lock rod 4 of one section of arc, the inwall of described hook 1 opening 8 side is fixed with pole 7, the middle part of described self-lock rod 4 is hinged on described pole 7, and perforation is offered in the side in the middle part of described self-lock rod 4, and on described pole 7, correspondence is provided with straight pin.

The course of work, under initial condition, described self-lock rod 4 suspends under self gravitation effect, spacing is there is in the upper end 5 of described self-lock rod 4 between inner side apart from described hook 1, lower end 6 and the described hook 1 of described self-lock rod 4 form cable 9 entrance, this coaster hangs on cable 9 by staff, coaster receive on fixed pulley 3 hang rope ladder and manpower effect press down, cable 9 pushes up to press on the upper end 5 of self-lock rod 4 and moves, until abut inside described hook 1, reach lock-out state, in this process, the lower end 6 of described self-lock rod 4 inwardly tilts and described cable 9 access space is reduced, cable 9 is avoided to deviate from, ensure the fail safe of this somersault coaster.

Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
