Abstract
The utility model provides a kind of auto lifting circuit closer of troleybus with spring, comprising: pipe link, and one end is movably connected on electric car top, and the other end is provided with and connects sparking plug; Chute, is arranged on this electric car top, which is provided with the slide block that can slide in chute; Driving engine, is connected with this slide block by stay cord, for controlling sliding of this slide block; Spring, one end is fixed on this pipe link, and the other end is connected with this slide block.The auto lifting circuit closer of troleybus that the utility model provides, can the action of Electric control wiring or off-line.
Description
Technical field
The utility model relates to public transport technical field, particularly a kind of auto lifting circuit closer of troleybus with spring.
Background technology
At present for the trackless trolley car of public conveyance and transportation, due to its have that noise is low, non-pollution discharge, startup are fast etc., and feature is applied by emphasis, known trackless cable tram circuit closer connects sparking plug by point type, pull bar, spring, stay cord form, by manually having pulled hanging wire or off-line task, once electric car goes offline, must stop and again pull mounting by driver and crew, easily cause traffic congestion, very inconvenient.And cannot off-line and hanging wire travel freely, the traveling of trackless cable tram and use are greatly limited.
Utility model content
Feature and advantage of the present utility model are partly stated in the following description, or can be apparent from this description, or learn by putting into practice the utility model.
For overcoming the problem of prior art, the utility model provides a kind of auto lifting circuit closer of troleybus with spring, it is characterized in that, comprising: pipe link, and one end is movably connected on electric car top, and the other end is provided with and connects sparking plug; Chute, is arranged on this electric car top, which is provided with the slide block that can slide in chute; Driving engine, is connected with this slide block by stay cord, for controlling sliding of this slide block; Spring, one end is fixed on this pipe link, and the other end is connected with this slide block.
Preferably, this chute is also provided with limiting stopper.
By reading specification sheets, those of ordinary skill in the art will understand the characteristic sum content of these technical schemes better.
Accompanying drawing explanation
Below by with reference to accompanying drawing describe the utility model particularly in conjunction with example, advantage of the present utility model and implementation will be more obvious, wherein content shown in accompanying drawing is only for explanation explanation of the present utility model, and do not form restriction of going up in all senses of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the auto lifting circuit closer of troleybus of the band spring of the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of auto lifting circuit closer of troleybus with spring, comprising: pipe link 1, and one end is movably connected on electric car top, and the other end is provided with and connects sparking plug 2; Chute 5, is arranged on this electric car top, which is provided with the slide block 4 that can slide in chute 5; Driving engine 7, is connected with slide block 4 by stay cord 8, for controlling sliding of slide block 4; Spring 3, one end is fixed on pipe link 1, and the other end is connected with slide block 4.Control slide block 4 by driving engine 7 to slide to the direction away from pipe link 1, then spring 3 will pull pipe link 1 upward movement, thus makes to connect sparking plug 2 and contact with electric wireline 9, completes hanging wire action; Namely equally can by starting 7 to control slide blocks 4 and slide near the direction of pipe link 1, then spring 3 will be lowerd pipe link 1, thus makes to connect sparking plug 2 and be separated with electric wireline 9, completes offline play.In order to the stretching preventing spring 3 unnecessary, in the present embodiment, this chute 5 is also provided with limiting stopper 6.The auto lifting circuit closer of troleybus that the utility model provides, can the action of Electric control wiring or off-line.
Above with reference to the accompanying drawings of preferred embodiment of the present utility model, those skilled in the art do not depart from scope of the present utility model and essence, and multiple flexible program can be had to realize the utility model.For example, to illustrate as the part of an embodiment or the feature that describes can be used for another embodiment to obtain another embodiment.These are only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model that the equivalence change that all utilization the utility model specification sheetss and accompanying drawing content are done all is contained within interest field of the present utility model.
