Description
Technical field
The utility model relates to a kind of termination, relates in particular to a kind of jockey of pilot lamp power line.
Background technology
The use power supply of bridge crane comes from the trolley being arranged on support rail beam, and trolley has four, and upper parallel is arranged the trolley of three 380 volts, and an earth connection is arranged in bottom.As shown in Figure 1, trolley 11 is fixedly connected with the angle steel 14 being arranged on support rail beam by pylon 12 and the bolt 13 being installed on trolley.Trolley 11 transmits power supply by the collector shoe 15 being arranged on crane, and collector shoe, along with the cart of crane moves back and forth, is done reciprocating action back and forth on trolley 11, its with trolley contact slide process in conduct electricity; Conventionally trolley adopts the section bar that material is copper alloy; its skin is surrounded by the reeded insulating protective layer 18 of tool; pylon 12 is just in time embedded in the groove that is installed on plastic protective layer 18; the parts that are connected with angle bar frame as trolley, a plurality of installation pylons 12 can play the effect that holds up trolley weight.In order to meet the needs of sliding line maintenance, trolley is divided into several sections of each other not conducting, connecting plate 16 by special-purpose sectioning between two trolleys connects, as required indicator light must be installed at sectioning place, the 4 core power lines 19 of powering for indicator light are arranged on respectively on the binding post 17 of two trolleys, each root trolley length is 12 meters, the reason that the reason of being expanded with heat and contract with cold due to trolley and collector shoe slidably reciprocate at trolley, trolley inevitably there will be play to some extent, play distance often reaches 120mm left and right.In order to prevent the play of trolley, power line 19 is curved suitable radian, the damaged amount when supplementing trolley play.
Once there are trolley 11 plaies, the angle bar frame of pylon of take is basic point, as shown in Figure 2, if trolley 11 is play left, power line 19 is can tension exceptionally straight, and the heart yearn that causes power line 19 is thrown off and the end of a thread exposes from binding post 17, or occurs the situation that heart yearn is pulled off; As shown in Figure 3, if trolley 11 is play to the right, 19 of power lines can shrink and arch upward, when sliding on trolley, collector shoe 15 will interfere with power line 19, after long-term friction, collector shoe will wear and tear cable insulation epidermis, both of these case all can cause the generation of security incident, exists huge potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of termination for trolley sectioning indicator light, it coordinates by scalable wire and pylon joint and sectioning, avoid unfavorable play due to trolley to cause wire tensioning exceptionally straight or shrink and arch upward, reduce the generation of the production accident causing thus, effectively ensured the safety in utilization of trolley.
In order to achieve the above object, the utility model provides a kind of termination of sectioning indicator light, and it comprises:

One in order to hang the pylon joint of trolley, and it is connected with one end of scalable wire;
One sectioning in order to be fixedly connected with trolley, it is connected with the other end of scalable wire.
In actual production process, because trolley is expanded with heat and contract with cold or collector shoe slidably reciprocates and makes play become a kind of inevitable phenomenon in trolley, the play of trolley can cause the tension of pilot lamp power line exceptionally straight under a kind of extreme case, in the next meeting of another kind of extreme case, cause its contraction to be arched upward, the former makes power line throw off and the end of a thread exposes from binding post, and the latter makes power line epidermis with collector shoe interference and rubs impaired.Termination of the present utility model, the power line adopting from trolley in prior art is different, adopting scalable wire is that the indicator light of sectioning is powered, at trolley play during near pylon joint, scalable wire shrinks along its length, and be positioned at all the time trolley top, can not interfere with collector shoe; At trolley play, during away from pylon joint, scalable wire stretches along its length, owing to having utilized pliability and the elasticity of scalable wire, can not make it in limit tensioned state.
In a kind of optimal technical scheme of the present utility model, above-mentioned pylon joint is removably connected with one end of scalable wire.Dismountable connection setting can be so that can repair replacing when any one parts breaks down or damages in pylon joint or scalable wire in time.
In another kind of optimal technical scheme of the present utility model, above-mentioned sectioning comprises sectionalizing joint, and sectionalizing joint is removably connected with the other end of scalable wire.Similarly, detachable connected mode can make sectionalizing joint or the repairing of sectioning replace and become more quick, convenient.
In addition, based on above-mentioned two kinds of optimal technical scheme, also the two ends of scalable wire removably can be connected with sectionalizing joint with pylon joint respectively.
Further, at the termination for trolley sectioning indicator light described in the utility model, above-mentioned wire is spring cable.
Further, the pylon joint of the termination for trolley sectioning indicator light described in the utility model is provided with internal thread hole, the hole wall of this internal thread hole is provided with the inside spin line mating with spring cable, so that spring cable is threadedly connected in internal thread hole.Because scalable wire adopts spring cable, in order to realize between pylon joint and wire, is more firmly connected, the pylon joint that employing has inside spin line mates and is connected with spring cable screw thread.
Further, the sectioning of the termination for trolley sectioning indicator light described in the utility model comprises sectionalizing joint, sectionalizing joint is provided with internal thread hole, the hole wall of this internal thread hole is provided with the inside spin line mating with spring cable, so that spring cable is threadedly connected in internal thread hole.
In addition, also pylon joint and sectionalizing joint are set to all have inside spin line on the hole wall of both internal thread holes simultaneously, to carry out screw thread coupling with spring cable, are connected.
Preferably, the axial length of above-mentioned inside spin line is set to 5 buttons.Inside spin line is processed as to 5 buttons and just can bears the stretching action power of spring cable completely.
Termination for trolley sectioning indicator light described in the utility model is the indicator light power supply of sectioning owing to having adopted telescopic wire, and it coordinates with pylon joint and sectioning, compare with the technical scheme of prior art, at trolley, occur in inevitable play situation, avoided that the tension of pilot lamp power line is exceptionally straight throws off from binding post, the contraction that has prevented minute pilot lamp power line is arched upward and is interfered and contact with collector shoe, the generation of the security incident that reduction causes due to pilot lamp power line.
Adopted the sliding contact line system of termination described in the utility model to have higher safe handling coefficient, system safety performance improves greatly, and running status is reliable and stable.
