Abstract

The utility model discloses a hard dropper contains: the stranded conductor, binding post and vertical type fastener are connected respectively to the both ends of stranded conductor, the other end of vertical type fastener be connected with the contact wire, a dropper fastener, one end with binding post connects, and the other end is connected with the carrier cable. The utility model discloses solve the hidden danger that subway train hung flexible contact net twine cha chu emergence contact wire side grinding through the chain contact effectively, in the time of can guaranteeing subway train pantograph process line trouble, the lifting power of two contact wire anchor sections is the same, avoids subway train pantograph goat's horn and contact wire side grinding, ensures the safety operation of track traffic.

Description

A kind of hard dropper

Technical field

The utility model is related to electric railway technical field, and in particular to a kind of hard dropper, is applied to track traffic chain Type contact suspension flexible contact netting twine Cha Chu.

Background technology

In the prior art, rail transportation operation circuit open air section uses chain contact suspension rigid suspension OCS, subway train When pantograph is by line trouble, the lifting force of the two contact line anchors of line Cha Chu section is different and cause pantograph goat's horn and contact line side The hidden danger of mill, serious meeting causes pantograph and catenary fault, and influence is brought to operation.

Utility model content

The purpose of this utility model is to provide a kind of hard dropper, efficiently solves subway train by chain contact suspension Flexible contact netting twine Cha Chu comes in contact the hidden danger of line side mill, it can be ensured that when subway train pantograph is branched off by line, two contacts The lifting force of line anchor section is identical, it is to avoid subway train pantograph goat's horn and contact line side grinding, ensures the safe operation of track traffic.

In order to achieve the above object, the utility model is achieved through the following technical solutions：A kind of hard dropper, is characterized in, Comprising：

Twisted wire；

The two ends of the twisted wire connect binding post and vertical type wire clamp respectively, the other end of described vertical type wire clamp with Contact line is connected；

One hanger ear, one end is connected with the binding post, and the other end is connected with carrier cable.

Described hard dropper is used for track traffic chain contact suspension flexible contact netting twine Cha Chu.

Described hard dropper also includes pvc pipe, and described pvc pipe is socketed in the outside of the twisted wire.

Described twisted wire and the material of binding post are copper.

The nominal area of section of described twisted wire is 150mm²；The nominal area of section of described binding post is 185mm²。

Described binding post includes the connecting plate and bushing that are sequentially connected, described connecting plate and the hanger ear, Described bushing is provided with the connecting hole of the receiving twisted wire.

The bushing of described binding post is with twisted wire using the connected mode for crimping.

Described hanger ear is connected with connecting plate by a connection piece.

Described connector is that the cooperation bolt is respectively equipped with a bolt, and described connecting plate and hanger ear The bolt hole for passing through.

A kind of hard dropper of the utility model has advantages below compared with prior art：Subway train pantograph is by chain When contact suspension flexible contact netting twine branches off, the lifting force of the contact line of pantograph contact is reduced, make the lifting of two contact line anchors section Power is identical, it is to avoid subway train pantograph goat's horn and contact line side grinding.

Specific embodiment

Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is done and is further explained State.

As shown in Fig. 1~Fig. 8, a kind of hard dropper, for track traffic chain contact suspension flexible contact netting twine Cha Chu, should Hard dropper is included：Twisted wire 100；The two ends of the twisted wire 100 connect binding post 200 and vertical type wire clamp 300 respectively, described The other end of vertical type wire clamp 300 is connected with contact line；One hanger ear 400, one end is connected with the binding post 200, separately One end is connected with carrier cable.

In the present embodiment, preferably, as shown in figure 1, hard dropper also includes a pvc pipe 500,500 sets of described pvc pipe It is connected on the outside of the twisted wire 100, the length of twisted wire 100 is determined according to live height, the length of pvc pipe 500 and the twisted wire 100 length is adapted.

In the present embodiment, preferably, the material of described twisted wire 100 and binding post 200 is copper；Preferably, institute The nominal area of section of the twisted wire 100 stated is 150mm²；The nominal area of section of described binding post 200 is 185mm²。

In the present embodiment, preferably, as shown in Figures 5 and 6, binding post 200 includes the connecting plate 201 being sequentially connected And bushing 202, described connecting plate 201 and the hanger ear 400, described bushing 202 is provided with the receiving twisted wire 100 Connecting hole；Preferably, the bushing 202 of described binding post 200 is with twisted wire 100 using the connected mode for crimping.

In the present embodiment, preferably, as shown in Fig. 5~Fig. 8, described hanger ear 400 passes through one with connecting plate 201 Connector 600 is connected；Preferably, described connector 600 is a bolt, and described connecting plate 201 and hanger ear 400 On be respectively equipped with the bolt hole for coordinating the bolt to pass through.

The assembly method of hard dropper：Twisted wire one end crimps after being connected with the bushing of binding post, the connecting plate of binding post Bolt hole be connected with M10 stainless steel bolts with hanger ear, twisted wire is put into 4 points of pvc pipes, by the twisted wire other end and vertical type Wire clamp is connected.

Concrete application：When subway train pantograph is branched off by chain contact suspension flexible contact netting twine, reduce pantograph and connect The lifting force of tactile contact line, makes the lifting force of two contact line anchors section identical, it is to avoid subway train pantograph goat's horn and contact line Side grinding.

Although content of the present utility model is discussed in detail by above preferred embodiment, but it should be appreciated that on The description stated is not considered as to limitation of the present utility model.After those skilled in the art have read the above, for Various modifications and substitutions of the present utility model all will be apparent.Therefore, protection domain of the present utility model should be by appended Claim limit.
