Description
Technical Field
The utility model relates to a wiping line field, concretely relates to wiping line current collector.
Background
The current collector is one of the most important parts on the sliding contact line, is mainly used for supplying power to mobile equipment, can slide on the sliding line track or can contact with the copper bar to take power;
at present, most of current collectors in the market are three-phase three-wire system current collectors and three-phase four-wire system current collectors, for the sake of convenience in installation, three phase arms or four phase arms are often fixedly installed on a square rod through a rod sleeve, so that the whole current collector is very heavy and is not suitable for being used in a more multi-phase (pole) system, and if one phase arm has a problem in the using process, the whole phase arm needs to be completely detached and replaced, which is very troublesome, time-consuming and labor-consuming;
in recent years, with the expansion of the field of using trolley lines, in the use examples of using trolley lines to satisfy mobile power supply, the system cannot be limited to the conventional power supply systems of three-phase three-wire system and three-phase four-wire system, and sometimes even the system is extended to signal transmission, power supply control of different frequencies and different voltages, and the like, and mobile power supply needs to be provided by the trolley lines, and the number of system phases can reach tens of poles (phases). Therefore, the current collector that originally only was applicable to three-phase three-wire system or three-phase four-wire system can not satisfy the market needs yet, designs on this basis the utility model discloses.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a wiping line current collector in order to solve above-mentioned problem to traditional wiping line current collector number of phases is single fixed among the solution prior art, can't make up looks arm quantity wantonly according to wiping line electric system's looks (utmost point) number demand, and the flexibility is poor, dismantles the replacement cost height moreover, wastes time and energy, and the practicality scheduling problem not strong. The utility model provides an among a great deal of technical scheme preferred technical scheme can realize that a rod cover only installs a looks arm to can be according to wiping line electric system's looks (utmost point) number demand arbitrary combination looks arm quantity, the flexibility is high, changes the maintenance simple and conveniently moreover, and is with low costs, and the practicality is good, sees the explanation below in detail.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a pair of wiping line current collector, including installation pole and the rod cover of suit on the installation pole, it has a looks arm to articulate on the rod cover.
As an important design of the scheme, the rod sleeve is fixedly connected with the mounting rod through a screw.
As the optimal design of the scheme, the cross section of the mounting rod is square, and the rod sleeve is tightly sleeved on the mounting rod in a sliding manner.
As an optimized design of the scheme, a plurality of rolling balls are rotatably arranged on the inner wall of the rod sleeve through rolling shafts, and a chute for the rolling balls to roll is formed in the mounting rod; and one end of the mounting rod is inserted with a plurality of locking pins.
Has the advantages that: wiping line current collector can realize that a rod cover only installs a phase arm, change the maintenance simple and convenient, with low costs, can make up phase arm quantity wantonly according to wiping line power consumption system's looks (utmost point) number demand moreover, the flexibility is high, the practicality is good.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The first embodiment is as follows: referring to fig. 1-4, the utility model provides a trolley wire collector, which comprises a mounting rod 1 and a rod sleeve 2 sleeved on the mounting rod 1, wherein a phase arm 3 is hinged on the rod sleeve 2, by the design, the number of the phase arms 3 can be randomly combined according to the phase (pole) number requirement of the trolley line power utilization system during use, the flexibility is high, the practicability is good, and only the damaged phase arm 3 needs to be replaced after one phase arm 3 is damaged, so that the replacement cost is effectively reduced, the cross section of the installation rod 1 is square, and the rod sleeve 2 is tightly sleeved on the installation rod 1 in a sliding manner, can prevent that rod cover 2 from rotating on installation pole 1, ensure that rod cover 2 can only slide along installation pole 1, compare the design that rod cover 2 fixed mounting was on installation pole 1 in the embodiment two, the problem that the collector brush drops from the slide frame is difficult to appear in this embodiment in the use.
As an optional implementation mode, a plurality of rolling balls 6 are rotatably mounted on the inner wall of the rod sleeve 2 through rolling shafts 5, and a sliding groove 4 for rolling the rolling balls 6 is formed in the mounting rod 1, so that the rod sleeve 2 can conveniently slide along the mounting rod 1, and the phenomenon that the rod sleeve 2 is clamped on the mounting rod 1 and cannot slide is avoided; one end of the installation rod 1 is inserted with a plurality of locking pins 7, and the locking pins 7 are arranged to prevent the rod sleeve 2 from slipping off and falling off from the installation rod 1.
Example two; referring to fig. 5, the present embodiment is different from the first embodiment only in the connection manner of the rod sleeve 2 and the mounting rod 1, in the present embodiment, the rod sleeve 2 is fixedly connected with the mounting rod 1 through the screw 8, and the current collector adopting this connection manner is simple and convenient to mount, dismount, and maintain, and has good practicability.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
