Abstract
The invention relates to a temperature compensation telescopic device of sliding contact lines, comprising sliding contact lines, conductive flexible connection lines, sliding sleeves and a sliding bar, wherein the head parts of the two sliding contact lines are provided with cutting narrow section parts, the narrow section parts at the head parts of the two sliding contact lines are mutually in lap joint, both ends of each conductive flexible connection line are respectively fixed at the side faces of the two sliding contact lines, and the two sliding sleeves are respectively fixed at the bottoms of the two sliding contact lines and are fixedly connected by the sliding bar. The device has simple structure, reasonable design, large strength and high accuracy, shortens the distance of the flexible connection lines, saves the cost and has very good economic benefit.
Description
Technical field
The present invention relates to a kind of slipping contact wire device, particularly relate to a kind of temperature compensation telescopic device of sliding contact lines.
Background technology
Rigid body trolley temperature compensation means, also be retractor device, its effect is the junction that makes two trolleys, has Telescopic, to digest the variation of the trolley joint gap that brings owing to expanding with heat and contract with cold, to keep being rigidly connected of trolley, electric conductivity simultaneously, and and electric slide plate between slip performance.Terms of settlement in the past is: as being rigidly connected of trolley, connecting cleat has the performance of slipping simultaneously with connecting cleat.Such structural disadvantages is that rigid nature is relatively poor, slip the plane and be difficult to accomplish accurately, and the conduction line that is flexible coupling is longer, influences alternate safety.
Summary of the invention
The present invention has overcome deficiency of the prior art, provides a kind of simple in structure, reasonable in design, and good rigidly slips the temperature compensation telescopic device of sliding contact lines of dependable performance.
In order to address the above problem, the present invention by the following technical solutions:
A kind of temperature compensation telescopic device of sliding contact lines, comprise trolley, conduction be flexible coupling line, sliding sleeve and slide bar, two trolley heads are provided with narrow section part of cutting, narrow section part of two trolley heads overlaps mutually, the be flexible coupling two ends of line of each conduction are separately fixed at the side of two trolleys, two sliding sleeves are separately fixed at two trolley bottoms, are connected and fixed by slide bar between two sliding sleeves.
Described sliding sleeve slide bar is the gauge member of highly versatile, is provided with slideway in each sliding sleeve, and slide bar passes slideway two sliding sleeves are linked together.
Compared with prior art, the invention has the beneficial effects as follows:
1, cancelled connecting cleat, the stretching structure that adopts sliding sleeve, slide bar to cooperate links together two trolleys, and highly versatile is made the efficient height, and rigidity is strong, guarantees that can there be enough bending resistances and tensile strength in the trolley junction under flexible situation.
2, the conductive plane that slips of trolley telescopic section is that two trolley ends are processed into and can be overlapped by trolley itself, so just guarantees the level and smooth unanimity of slipping conductive plane of trolley easily, and conductive plane is big, and conductive effect is good.
3, owing to cancelled connecting cleat, the line that is flexible coupling of conduction can be accomplished the shortest, has not only improved conductive security, has also saved material, has improved the performance of enterprises.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is Fig. 1 birds-eye view;
Fig. 3 is Fig. 1 left view;
Fig. 4 is the temperature compensation telescopic device of sliding contact lines structural representation before improving.
The specific embodiment
A kind of temperature compensation telescopic device of sliding contact lines, as Fig. 1～shown in Figure 3, comprise trolley 1, conduction be flexible coupling line 2, sliding sleeve 3 and slide bar 4, two trolley 1 heads are provided with narrow section part of cutting, narrow section part of two trolley 1 heads overlaps mutually, each conduction is flexible coupling the two ends of line 2 respectively by being bolted to the side of two trolleys 1, two sliding sleeves 3 are weldingly fixed on two trolley 1 bottoms respectively, be provided with two slideways in each sliding sleeve 3, slide bar 4 passes slideway two sliding sleeves 3 is linked together.Slide bar 4 adopts round steel to make, and can guarantee that trolley 1 junction has enough bending strengths under flexible situation.Apparatus of the present invention can be made the general-duty mechanical part, and his intensity and flexible distance can design arbitrarily, and the line and slip the plane of need not considering to be flexible coupling, and intensity is big, and the precision height is in that do not consider can the normalisation batch manufacturing under the concrete slip model.
Temperature compensation telescopic device of sliding contact lines before improving links to each other by connecting cleat 5 between two trolleys 1 as shown in Figure 4, and two trolley 1 heads leave the slit, rely on connecting cleat 5 as the transition portion that slips, the conduction line 2 that is flexible coupling is longer, causes waste, also influences alternate safety simultaneously.
Claims (2)
1, a kind of temperature compensation telescopic device of sliding contact lines, it is characterized in that, comprise trolley, conduction be flexible coupling line, sliding sleeve and slide bar, two trolley heads are provided with narrow section part of cutting, narrow section part of two trolley heads overlaps mutually, the be flexible coupling two ends of line of each conduction are separately fixed at the side of two trolleys, and two sliding sleeves are separately fixed at two trolleys bottoms, are connected and fixed by slide bar between two sliding sleeves.
