Description

Sliding contact line system

Technical Field

The invention relates to the technical field of trolley line equipment, in particular to a trolley line system.

Background

The trolley line system is a special wire for supplying power to mobile equipment (mainly elevators, cranes, traveling cranes, and the like). The power on the trolley line is supplied to the electric equipment through the current collector. The rain-proof performance of traditional wiping line system and construction elevator of formula is not good, especially gets into the wiping wire casing in the opening of wiping wire casing under the effect of wind easily at the weather rainwater that the wind and rain was handed over, contacts with the conductive element in the wiping wire casing, causes the risk easily. Secondly, because the outdoor temperature difference is very big, the connection between upper and lower current conducting plate is because the expend with heat and contract with cold deformation easily for the current conducting plate is easy warp to warp and is out of shape. Thirdly, the traditional current collector is easy to damage due to sliding friction in the using process, the balance is poor, a single electrode is easy to damage due to overlarge current, the service life is short, and the stability is poor.

It should be noted that, especially, the trolley line system in a complex environment such as a workshop is generally in a full-load working state for a long time, and due to the influence of external factors such as a field environment or corrosivity, the trolley line has a certain displacement in the horizontal direction, the upper part and the lower part, and a part of the position is slightly deformed, so that the sheaths of the abutting parts of the trolley line are deformed and damaged, water vapor in the external environment is immersed, and a great potential safety hazard is caused.

In view of the foregoing, there is a need for a trolley wire system that avoids the presence of moisture within the trolley wire.

Disclosure of Invention

The invention aims to provide a trolley line system, which is used for solving the problem that sealing water vapor easily exists in the trolley line system in the prior art.

The invention is realized by the following technical scheme:

a trolley line system comprises a fixed frame and a plurality of track frames, wherein the track frames are uniformly distributed on the fixed frame at intervals, the trolley line system also comprises a trolley line, a strainer and a sliding head, the trolley line is fixed on the track frames, flow guide parts are arranged at two end parts of the trolley line, the strainer is arranged on the fixed frame and connected with the flow guide parts, the sliding head is arranged on the trolley line in a sliding mode, a sealing part is arranged at the opening end of the trolley line, and the trolley line and the flow guide parts are identical in cross section structure; the flow guide piece comprises a flow guide body and a flow guide plate, the inside of the flow guide body is divided into four induction areas through the flow guide plate, the four induction areas are symmetrical to the axis of the flow guide body, magnetic fields are distributed among the induction areas, and when the sliding head slides, the magnetic induction lines among the induction areas can be cut. It should be noted that, in the prior art, a trolley line system in a complex environment such as a workshop is generally in a full-load working state for a long time, and due to the influence of external factors such as a field environment or corrosivity, the level, the upper part and the lower part of the trolley line have certain displacement, and a part of the position slightly deforms, so that a sheath at the butt joint part of the trolley line deforms and is damaged, water vapor in the external environment is immersed, and a great potential safety hazard is caused. In view of the above, the applicant has proposed a trolley line system for insulating the moisture of the external environment, in particular by providing a seal at the open end of the trolley line.

However, in practical use of the trolley line, the applicant finds that part of water vapor still exists inside the trolley line, namely, in the sliding process of the sliding head, the sealing element cannot be sealed with the sliding head in a sliding state in real time, and the flowing part of water vapor still enters the trolley line, so that potential safety hazards are caused. In order to solve the problem, the applicant proposes that an induction area is arranged in the sliding contact line, a magnetic field exists in the induction area, and when the sliding head slides, the sliding head is made of a metal material, so that the sliding head can perform cutting magnetic induction line movement in the magnetic field in the induction area, and an electric field is generated. It should be further noted that, because the movement trend of the slider needs to be changed according to the actual use state of the electrical appliance, that is, the slider has uncertainty, at this time, the slider has induced potential in the generated electric field, so that the slider is subjected to electromagnetic induction to generate partial heat, and the partial heat is conducted outside the slider through an air medium, so that the air humidity inside the trolley line is reduced, and therefore, the moisture condensation is avoided, and safety accidents are caused.

It should be noted that, in the prior art, a trolley line 3 system in a complex environment such as a workshop is generally in a full-load working state for a long time, and due to the influence of external factors such as a field environment or corrosivity, the level, the upper part and the lower part of the trolley line 3 have certain displacement, and a part of the position slightly deforms, so that a sheath of a butt joint part of the trolley line 3 deforms and is damaged, water vapor in the external environment enters, and great potential safety hazards are caused. In view of the above, the applicant has proposed a trolley line system for insulating the moisture of the external environment, in particular by providing a seal 7 at the open end of the trolley line 3.

In order to solve the problem, the applicant proposes to provide the sensing areas 65 inside the trolley wires 3, and the magnetic field exists between the sensing areas 65, so that when the slider 4 slides, the slider 4 is made of a metal material, and can perform cutting magnetic induction line movement in the magnetic field between the sensing areas 65, thereby generating an electric field. It should be further noted that, because the movement trend of the slider 4 needs to be changed according to the actual use state of the electrical appliance, that is, the slider 4 has uncertainty, at this time, the slider 4 has induced potential in the generated electric field, so as to receive electromagnetic induction to generate partial heat, and the partial heat is conducted outside the slider 4 through an air medium, so as to reduce the air humidity inside the trolley wire 3, thereby avoiding water vapor condensation and causing safety accidents.
