Abstract

The utility model discloses an anti-reversion mechanism for line vehicle type protecting net, which is provided for resolving the defaults that the structure of the anti-reversion mechanism on the prior line vehicle type protecting net is complex, the production and the processing are troublesome, and the disassembly are easy to go to failure. The anti-reversion mechanism comprises a toothed bar with thorn teeth at the lower end and installed at one side of the erecting pole on the line vehicle type protecting net, and a toothed disc fixed vertically on the roll of an erecting pole periphery, wherein the toothed bar is installed in the way that the erecting toothed bar is installed in a vertical sliding way in a branch sleeve fixed at one side of the erecting pole; the toothed disc is arranged in the way that a plurality of thorn teeth inserting holes that evenly distributed in the same radius around the erecting pole centre line, and when the toothed disc is rotating, the inserting holes can correspond to the thorn teeth, are arranged on a round disc. Because the anti-reversion of the mechanism is realized by inserting the thorn teeth inclined face into the thorn teeth inserting holes on the toothed disc in a unidirectional way, and the toothed disc is easy to be manufactured; the toothed bar is meshed with the toothed disc by deadweight, the inclined face is pushed to take off and separated by turning the toothed disc, the structure is simple, the components are few, the failure is not easy to occur when the mechanism is used, and the manufacturing cost is low.

Description

The anti-reversing gearbox of line car formula protecting wire net

Technical field

The utility model is a kind of anti-reversing gearbox of doing isolating and protecting with protecting wire net.

Background technology

The transformer station of power system is when relevant power equipments such as installation, maintenance, maintenance, and according to the requirement of electrical trouble free service rules, when Off Limits was worked, the security protection facility must be set up in the periphery in this zone.Making the line car formula protecting wire net that is used as the security protection facility at present, is in the vertical rod that can be erected in ground, is wound with protective screening around the vertical rod periphery, when protective screening is launched from the periphery of vertical rod, can carry out enclosing to the protection region; After finishing, the protective screening of line car formula protecting wire net can be packed up around the vertical rod coiling, in order to reusing at place's site construction.Protective screening fence volume behind the coiling is little, in light weight, and installation, dismounting, carrying and storage are all very convenient, are subjected to users' welcome deeply.

Line car formula protecting wire net is in the process of expansion and rolling protective screening, because the phenomenon that reverses around vertical rod appears in the tension of protective screening easily.In order to control the reverse of protective screening, generally be at present between the reel of vertical rod periphery and vertical rod, to install the ratchet ratch mechanism additional, promptly adding the sour jujube retainer with vertical rod all-in-one-piece top cover one side, the sour jujube tooth bar of bottom band sour jujube tooth is installed on the sour jujube retainer; Be fixed with the sour jujube chain wheel on the reel of vertical rod periphery below the sour jujube tooth bar, rotate the sour jujube chain wheel, sour jujube tooth bar pulls out wooden fork, swings weight by what be installed in that the top puts, makes sour jujube tooth on it leave or insert between ratchet on the sour jujube chain wheel.When protective screening took a turn for the worse, the projection on sour jujube tooth inclined-plane was inserted between two ratchets of sour jujube chain wheel, prevents the reverse of protective screening.

Existing sour jujube tooth stop mechanism is owing to additional have a plurality of as the sour jujube retainer, pull out wooden fork, swing accessories such as weight, its complex structure, processing are extremely loaded down with trivial details, and especially in use dismounting is frequent, easily cause mechanism malfunctioning, thereby cause this product normally not use.

The utility model content

Technical problem to be solved in the utility model is, overcomes the anti-ratchet ratch mechanism complex structure that reverses on the prior art line car formula protecting wire net, and production and processing is loaded down with trivial details, and dismounting is prone to malfunctioning shortcoming, and a kind of anti-reversing gearbox of line car formula protecting wire net is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the anti-reversing gearbox of line car formula protecting wire net comprises: vertical rod one side on the online car formula protecting wire net, the sour jujube tooth bar of lower end band sour jujube tooth are installed, and below the sour jujube tooth in the vertical rod periphery, make the sour jujube chain wheel of vertical fixing above the reel that the coiling protective screening uses, sour jujube tooth and sour jujube chain wheel form the ratchet ratch mechanism, the installation of described sour jujube tooth bar is that the sour jujube tooth bar that will erect can slide up and down to be installed in the spider that is fixed in vertical rod one side; Described sour jujube chain wheel is on a circular card, is provided with a plurality of sour jujube eye cuttings hole uniform around radiuses such as vertical rod center lines, can be corresponding with the sour jujube tooth when rotating.

The utility model also has following technical characterictic:

The ratchet ratch mechanism that the sour jujube chain wheel in described sour jujube tooth and band sour jujube eye cutting hole forms, be when the lower surface of sour jujube tooth bar leans against the card of sour jujube chain wheel, the sour jujube tooth lower end of inserting sour jujube eye cutting hole tilts along sour jujube chain wheel direction of rotation, and the peak on its inclined-plane is suitable for reading just above sour jujube eye cutting hole;

Side at described spider is provided with the inverted L shape chute, and a side of sour jujube tooth bar is fixed with the position fixing handle that can slide in the inverted L shape chute.

During use, the sour jujube tooth bar that is installed in vertical rod one side can fall automatically by deadweight, and the sour jujube tooth of its lower end falls in the sour jujube eye cutting hole on the sour jujube chain wheel; When the incline direction of the suitable sour jujube tooth of sour jujube chain wheel rotated, the sour jujube tooth can takeoff from each sour jujube eye cutting hole smoothly protective screening is launched; When stopping operating, because of the sour jujube eye cutting is gone in the sour jujube eye cutting hole, under the effect of sour jujube tooth lower end inclination cusp, even if protective screening has reciprocal pulling force, the sour jujube tooth can not take-off reverse the sour jujube chain wheel.

Advantage of the present utility model and good effect are, because the anti-reversing gearbox on this line car formula protecting wire net, what adopt is the sour jujube tooth that has below sour jujube tooth bar to a direction inclined plane, the sour jujube eye cutting goes into to make in the sour jujube eye cutting hole that the sour jujube chain wheel is irreversible transfers realization, the making of sour jujube chain wheel, be only on card a plurality of equidistant sour jujube eye cutting holes of drum face centre drill get final product, and sour jujube tooth bar is can fall to making sour jujube tooth and the engagement of sour jujube chain wheel automatically by deadweight, when the sour jujube chain wheel rotates, push away the inclined-plane take-off of sour jujube tooth by sour jujube eye cutting hole suitable for reading and leave the sour jujube chain wheel, simple in structure, component processing is convenient, anti-reverse leans on the retaining suitable for reading in sour jujube eye cutting hole on the facade relative with sour jujube tooth inclined-plane, safe and reliable, compared with prior art, saved a plurality of component, be difficult for during use producing fault, cost of manufacture is low.
