Description

Rail type sliding contact power supply device
Technical Field
The invention belongs to the technical field of feed devices, and particularly relates to a rail type sliding contact power supply device.
Background
The above-mentioned rail-type sliding contact power supply device is mainly used for a cloth spreading machine, but can also be used for an electronic and electrical product testing production line and the like. The aforementioned spreading machines such as CN103991750B (cloth pressing device of spreading machine), CN104003231B (edge peeling and fixing device of spreading machine), and CN105887461A (cloth cutting device of spreading machine), etc.; the aforementioned cloth spreading machines are, for example, CN102633155A (a cloth pressing device of the cloth spreading machine), CN102642743A (a slide rail structure for a cloth spreading roller of the cloth spreading machine), and CN102633157A (a cloth spreading roller structure of a cloth spreading mechanism of the cloth spreading machine), etc.
Taking a cloth paving machine as an example, the cloth paving machine is used for flattening rolled cloth and folding the rolled cloth into a plurality of layers, a cloth paving trolley of a travelling mechanism is driven to reciprocate on a cloth paving workbench by a driving motor fixedly arranged on the cloth paving machine, and a power wire of the driving motor also reciprocates along with the cloth paving trolley during the reciprocating traveling. Therefore, the length of the power line is quite long because the length of the power line needs to be matched with the traveling stroke of the cloth spreading trolley. At present, the power cord of the driving motor, i.e. the power cord electrically connected with the driving motor, is usually placed on the ground without regulation, so that the following technical problems exist: first, since the power cord is freely placed on the ground and is frequently dragged along with the reciprocating motion of the driving motor, it is easily damaged and causes electric leakage, causing an undesirable but difficult to stop ground fault; secondly, the electric connection part of the power line and the driving motor is easy to loosen, so that regular or irregular maintenance is needed, and the daily working intensity of electric maintenance personnel is increased; thirdly, the power line is easy to interfere with nearby objects due to lack of effective shielding and reasonable control.
The applicant searches documents and retrieves 'a power line suspension walking device of a cloth paving machine' recommended by Chinese patent authorization publication No. CN204668894U, and the patent scheme is established by the following steps: the power line is hung on the plurality of hanging parts in a multi-section manner, and when the cloth paving machine walks in a reciprocating manner, the power line can pull the hanging parts to walk on the walking track; when the cloth spreading machine works or does not work, the power lines are orderly hung on the edges of the cloth spreading platform, so that the power lines are prevented from being damaged (see paragraph 0014 in the specification specifically). However, since the length of the power line cannot be shortened, the patent has the disadvantage of addressing symptoms rather than addressing the root causes.

Detailed Description
In order to make the technical spirit and advantages of the present invention more clearly understood, the applicant below describes in detail by way of example, but the description of the example is not intended to limit the technical scope of the present invention, and any equivalent changes made according to the inventive concept, which are merely in form and are not essential, should be considered as the technical scope of the present invention.
In the following description, all the concepts related to the directions or orientations of up, down, left, right, front and rear are, except for others, in the position state shown in fig. 1, and thus should not be understood as particularly limiting the technical solution provided by the present invention. For example: the position shown in figure 3 is exactly the opposite of the position shown in figure 1 and is intended to facilitate and clearly show the structure of the trolley rail extension connection 6.
Example 1:
referring to fig. 1 in combination with fig. 3, a hanger bracket 1 is shown, the hanger bracket 1 is fixed with a frame 8 of a spreading machine, more precisely, with a spreading work table foot of the frame 8 of the spreading machine, by a hanger bracket fixing screw 12 in a use state, if the present invention is applied to an electrical and electronic product testing production line, the hanger bracket 1 is fixed with the test work table foot of the frame 8 of the electrical and electronic product testing production line by the hanger bracket fixing screw 12. A boom 11 is disposed on the hanger bracket 1 through a pair of boom adjusting nuts 112, and a pair of hanger pins 111 disposed to face each other are fixed to the lower end of the boom 11; a trolley rail 2 is shown, which trolley rail 2 is supported on a pair of hanger clamp feet 111 at a position corresponding to a hanger clamp foot cavity 1111 of the pair of hanger clamp feet 111; a plurality of conductive rail insulation fixing seats 3 (shown in fig. 3) made of plastic or ceramic are shown, wherein the conductive rail insulation fixing seats 3 are distributed at intervals along the length direction of the pulley guide rail 2 and are fixedly embedded with the top wall of the pulley guide cavity 21 in the pulley guide cavity 21 of the pulley guide rail 2; the conductor rails 4 are shown, three conductor rails 4 are arranged, and the conductor rails 4 are fixedly embedded with the downward side of the conductor rail insulating fixed seat 3; a power feeding pulley mechanism 5 is shown, which power feeding pulley mechanism 5 is arranged in the pulley guide rail cavity 21 and is in sliding fit with the conductor rail 4 in a state of forming a rolling pair with the pulley guide rail cavity 21; a pulley guide rail lengthening connecting mechanism 6 is shown, and the pulley guide rail lengthening connecting mechanism 6 is connected between two adjacent pulley guide rails 2 from head to tail; a power supply wiring mechanism 7 is shown, which power supply wiring mechanism 7 corresponds to the lower side of the aforementioned trolley guide rail 2, to which power supply wiring mechanism 7 the aforementioned feed trolley mechanism 5 is fixed and which is electrically connected to the power supply wiring mechanism 7.

The longer the length of the trolley guide 2, the greater the number of the aforementioned hanger brackets 1, and the total length of the trolley guide 2 depends on the length of the work table of the spreader or on the length of the test work table of the electrical and electronic product test line. In addition, since the length of the pulley rail 2 itself is limited, the two adjacent pulley rails 2 end to end need to be connected end to end by means of the pulley rail lengthening connection mechanism 6, and the conductor rail 4 is the same as that in the following (also described below).
