Embodiment 1

[0044] figure 1 It is a schematic diagram of the structure of the load-bearing cable clip provided by Embodiment 1 of the present invention. The catenary cable clamp provided in this embodiment can be specifically used in contact suspension of an overhead catenary. The function of the contact suspension is to conduct electric energy to the power supply equipment of the EMU. It is composed of load-bearing cables, contact wires, suspension strings, positioners, compensation devices, suspension parts and central anchors, etc., mainly including simple suspensions and chains. There are two ways to hang. The suspension in which the contact line is suspended on the catenary cable through the suspension string is called chain suspension. In the chain suspension, the catenary cable is suspended on the supporting device of the pillar, and the contact line is suspended on the catenary cable through the suspension string, so that In the case of no additional pillars, adding suspension p...

Embodiment 2

[0059] figure 2 It is a schematic diagram of the structure of the hanging string provided by Embodiment 2 of the present invention. Such as figure 2 As shown, the suspension string provided in this embodiment includes the suspension string wire 8, the contact wire clamp and the load-bearing wire clamp described in any of the above-mentioned embodiments. Wherein, the bottom end of the bearing cable clamp is connected with the top end of the suspension string 8, and the top end of the contact wire clamp is connected with the bottom end of the suspension string 8. Specifically, the top end of the suspension string 8 can be bent into a closed loop, and the first clamp 1 of the catenary cable clamp can pass through the closed loop.

[0060] from figure 2 It can be seen from the figure that the first clamp 1 and the first bolt 3 enclose a space for the suspension string 8 to pass through, and the top of the suspension string 8 passes through this space. Since the cross section...

Embodiment 3

[0073] Figure 4 It is a schematic structural diagram of the contact suspension provided by Embodiment 3 of the present invention. Such as Figure 4 As shown, the contact suspension provided in this embodiment includes catenary cables 14, contact wires 15 and at least one hanging string described in any of the above-mentioned embodiments;

[0074] Wherein, the catenary wire 14 passes through the second clamp 2 of the catenary wire clamp, and the contact wire 15 is clamped in the mouth 13 of the contact wire clamp. A gap is formed between the second wire clip 2 and the catenary cable 14, and a gap is formed between the U-shaped clip 9 and the suspension string 8.

[0075] Since the catenary cable 14 needs to bear the gravity of the contact line 15, the material of the catenary cable 14 should be soft, able to withstand a large tension, the change of sag should be small when the temperature changes, and it should have a certain conductivity. The structure of the catenary cabl...

Abstract

The invention provides a bearing rope clamp, a dropper and a contact suspension. The bearing rope clamp comprises a first clip, a second clip, a first bolt, a first nut and an electric contact member, wherein both the first clip and the second clip are provided with two extension parts which extend oppositely; the extension parts of the first clip face the extension parts of the second clip; the end parts of the two extension parts of the first clip are oppositely provided with first through holes respectively; the end parts of the two extension parts of the second clip are oppositely provided with second through holes respectively; the electric contact member is arranged between the head of the first bolt and the first nut; the first bolt penetrates the first through holes and the second through holes; the tail part of the first bolt is in screw joint with the first nut; the first nut clamps the first clip, the second clip and the electric contact member between the bolt head of the first bolt and the first nut. The bearing rope clamp, the dropper and the contact suspension provided by the invention can improve the safety of the contact suspension.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a tension cable clip, a hanging string and a contact suspension. Background technique [0002] The rail transit engineering catenary system, including the catenary, rail loop, feeder and return line, is the direct link in the rail transit power supply system to supply power to the EMUs. The catenary is a kind of transmission network laid on the track and kept at a certain distance from the top of the railway track. Through the sliding contact between the pantograph (or current collector) of the EMU and the catenary, the traction electric energy enters the EMU from the catenary to drive the traction motor to make the train run. Commonly used catenary is composed of several parts such as contact suspension, pillar and foundation. [0003] At present, the contact suspension is mostly composed of catenary cables, contact wires, suspension strings and other devices, and its function is to co...
