Abstract
The utility model belongs to the technical field of power supply devices and particularly relates to a trench conductive device. The trench conductive device comprises an adjustable bolt, a spring, a sliding block and a trench sliding-contact wire, which are arranged on a beam of a conductive trolley, wherein the adjustable bolt is externally sheathed with an insulating sliding sleeve; and an oval groove is formed in the beam of the conductive trolley. The trench conductive device aims at solving the problems that since an existing trench conductive device is unreasonable in structural design, after the device is used for a long time, angle steel becomes unparallel with a sliding block, a sliding chute is abraded unevenly, the sliding block loosens with sparks and is detached from the angle steel to fall into the bottom of a trench, and consequently, the effect of power supply is affected.
Description
Technical field
The utility model belongs to the electric supply installation technical field, is specifically related to the trench electric installation.
Background technology
The power supply mode of the large-scale crane on track such as transfer crane often adopts three angle steel to do sliding contact line of trench, the conduction trolley frame of slide block is housed along with crane moves, thereby electricity is sent on hoisting crane by angle steel and slide block.Now present, the structure design of trench electric installation is fairly simple, uses also more convenient.But, due to three angle steel install be difficult for parallel, angle steel use be easy to occur after a period of time crooked, slide block is installed on the conduction dolly, and is not parallel with angle steel, makes between slide block and angle steel and sometimes kills, sometimes unclamp, cause that the chute wearing and tearing are uneven, cause frequently changing slide block; Spark perhaps appears when slide block unclamps; When crossing pine, slide block easily breaks away from angle steel and falls into bottom of trench, and this has affected the power supply effect to a great extent, thereby affects the normal operation of hoisting crane.
The utility model content
The purpose of this utility model: thus for solve existing trench electric installation structure design unreasonable and bring after long-time use angle steel and slide block not parallel cause the chute wearing and tearing uneven, spark appears when slide block unclamps and slide block breaks away from the problem that angle steel falls into bottom of trench impact power supply effect, and proposition trench electric installation.
The technical solution of the utility model: the trench electric installation, comprise the adjusting bolt, spring, slide block and the sliding contact line of trench that are arranged on the conduction craneway, described adjusting bolt is arranged with the insulation slip cap outward, and described conduction craneway offers an oval groove.
Trench electric installation of the present utility model, because adjusting bolt is arranged with the insulation slip cap outward, the conduction craneway offers an oval groove, therefore in the process of using, the insulation slip cap can slide in oval groove, thereby make slide block can adapt to the not parallel of angle steel, avoid to a great extent the chute wearing and tearing, reduced the frequency that slide block is changed, and avoided occurring the phenomenon of spark, slide block difficult drop-off angle steel and fall into bottom of trench has improved the power supply effect greatly.
Further, described insulation slip cap is fixed by angle steel.
Because the insulation slip cap is fixed by angle steel, therefore avoided the insulation slip cap in the process of work, end float misalignment to occur.
Description of drawings
Fig. 1 is the structural representation of the embodiment of trench electric installation of the present utility model;
Fig. 2 is the enlarged diagram of A-A in Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the utility model provides the trench electric installation, comprise the adjusting bolt 1, spring 4, slide block 6 and the sliding contact line of trench 7 that are arranged on conduction craneway 2, the outer insulation slip cap 8 that is arranged with of adjusting bolt 1, and insulation slip cap 8 is fixing by angle steel 10, and conduction craneway 2 offers an oval groove 9.
In the present embodiment, arranging of insulation slip cap 8 is very crucial, and insulation slip cap 8 can make adjusting bolt 1 that adaptive slip occurs, thereby makes slide block 6 and sliding contact line of trench 7 adapt.Insulation slip cap 8 is fixing by angle steel 10, and the main slip cap 8 of considering to avoid insulating in the process of work, end float misalignment occurs.
In addition, the setting of oval groove 9 makes insulation slip cap 8 that certain sliding scale can be arranged, thereby guarantees the comformability of slide block 6 and sliding contact line of trench 7, improves the power supply effect.
The top that it is pointed out that spring 4 is provided with insulated spring cap 3, and the bottom of spring 4 is provided with insulated spring seat 5, and insulated spring cap 3 is connected with adjusting bolt 1, and insulated spring seat 5 is connected with slide block 6.
Above-described is only preferred implementation of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not affect effect and practical applicability that the utility model is implemented.
