Abstract
The invention discloses a trunk line electrification contact network tool dropper, comprising a suspension mechanism, a clamping device, a flexible mechanism and a ratchet mechanism, wherein the suspension mechanism is used for hooking a carrier cable, the clamping device is used for pressing the carrier cable, the flexible mechanism is used for controlling the reciprocating motion of the clamping device, and the ratchet mechanism is arranged on the tail end of the suspension mechanism and is provided with a reeling and unreeling steel wire rope which is used for lifting the contact network. The installation process of the contact network tool dropper is as follows: firstly, hooking a hanger on the carrier cable; screwing a pressing structure to cause a locating part to be arranged in the straightaway of an inverse 'L'-shaped chute; under the tension action, ensuring that a rubber mount is matched with the hanger to press the carrier cable, and realizing the fact that the whole tool dropper is positioned on the carrier cable; wrapping up the contact reticle by the reeling and unreeling steel wire rope, wherein the contact reticle is arranged on a protective sleeve; rotating and tightening a ratchet device; lifting the contact reticle to the set height; installing a contact network dropper; releasing and unfastening the reeling and unreeling steel wire rope; resetting the pressing mechanism; and moving the tool dropper to carry out operation on the next operation point. The invention initiates the accessory appliance of a brand-new contact network top chord.
Description
Technical field
Patent of the present invention relates to the railway electrification service tool, concrete trunk line electrification contact network tool dropper.
Background technology
At present, in the electrification contact network payingoff construction, dropper to be installed between final catenary and the contact wire; Because the unwrapping wire time is very short, in unwrapping wire dropper can't be installed.In order to guarantee that smooth unwrapping wire normally installs dropper at this catenary and contact wire temporarily, it mainly is the binding iron wire, when dropper is installed, iron wire is cut off, and wastes very big.After serve unit in charge of construction and also developed some interim measures, collude as s, tie up rope etc., all undesirable.The not basic unwrapping wire time weak point that solves will be fixed with catenary after the installation, can move with contact wire, and not damage the problem of contact wire.
Summary of the invention
The problem to be solved in the present invention provides a kind of trunk line electrification contact network tool dropper, it is in the railway electrification construction, when contact system is put in exhibition, set up a kind of reusable device that catenary links to each other with contact wire, solve the problem in the existing electrification contact network payingoff construction, improve the unwrapping wire efficient of contact wire and the installation effectiveness of dropper.
For the technical scheme that addresses the above problem employing is:
Trunk line electrification contact network tool dropper of the present invention, comprise and be used for hitch that catenary is caught on, be used to compress the fixing device of catenary, and with control reciprocating telescoping mechanism of fixing device and the ratchet device that is arranged at the hitch end, be provided for promoting the folding and unfolding steel rope of contact system on the ratchet device.
Described hitch is a strip, and the top is provided with hook; Fixing device is movably set in hitch, and the top is provided with the hook of hitch and cooperates the rubber base that compresses catenary, and inverted "L" shaped positioning runner is offered at the fixing device middle part, and position-limited lever is arranged in positioning runner and captives joint with hitch; Telescoping mechanism is the below in fixing device, and it is for being the retracing spring on the strip in hitch, and the position of the hitch strip of retracing spring lower end is provided with the spring locating part.
Described folding and unfolding steel rope is provided with and promotes is the protecting pipe that is used to protect contact system.
It is ring-like that rubber base upper surface depression is semicircle, and the annulus inside radius is load bands footpath, links up with to be shallow hook, made by the little steel pipe end that bends, and the other end adopts screw thread to tighten with escapement to be connected.
Protecting pipe adopts copper pipe.
Installing contact net dropper process: earlier hook is caught on catenary, turn compressing structure, make locating part be in the straight way of inverted "L" shaped chute, under the tension force effect of spring, rubber base cooperates hook to compress catenary, and realization entire tool dropper is located on catenary; Catch the contact netting twine with the folding and unfolding steel rope again, and the contact netting twine is positioned on the protecting pipe, rotates tight escapement, the contact netting twine is risen to the height of setting, installing contact net dropper then.The folding and unfolding steel is untied in relieving, and the compressing structure that resets, Move tool dropper carry out next setting operation.
Good effect of the present invention is: the instrument dropper clamps catenary, avoids moving on catenary, install simultaneously, and convenient disassembly, in light weight, do not damage contact wire, started the accessory appliances that a kind of brand new electrification contact network winds up.
Description of drawings
The structural representation of Fig. 1, trunk line electrification contact network tool dropper of the present invention.
The specific embodiment
Trunk line electrification contact network tool dropper as shown in Figure 1, comprise and be used for hitch 1 that catenary is caught on, be used to compress the fixing device 2 of catenary, and with control fixing device 2 reciprocating telescoping mechanisms 3 and the ratchet device 5 that is arranged at hitch 1 end, be provided for promoting the folding and unfolding steel rope 7 of contact system on the ratchet device 5.Described hitch 1 is a strip, and the top is provided with hook; Fixing device 2 is movably set in hitch 2, the top is provided with the hook of hitch 1 and cooperates the rubber base 21 that compresses catenary, inverted "L" shaped positioning runner 22 is offered at fixing device 2 middle parts, and position-limited lever 4 is arranged in positioning runner 22 and captives joint with hitch 1; Telescoping mechanism 3 is in the below of fixing device 2, and it is to be the retracing spring on the strip in hitch 1, and the position of hitch 1 strip of retracing spring lower end is provided with spring locating part 31.Described folding and unfolding steel rope 7 is provided with and promotes is the protecting pipe 6 that is used to protect contact system.Protecting pipe 6 adopts copper pipe.
It is ring-like that rubber base 21 upper surfaces depressions is semicircle, and the annulus inside radius is load bands footpath, links up with to be shallow hook, made by the little steel pipe end that bends, and the other end adopts screw thread and escapement to tighten.Folding and unfolding steel rope 7 adopts the 6mm steel rope of band moccasin, and protecting pipe 6 can rotate on folding and unfolding steel rope 7.Make protecting pipe 6 and contact the netting twine friction of rolling, do not hinder the contact netting twine.
