Problems solved by technology

[0004] The purpose of the present invention is to provide a 1:2 triangular tooth ratchet compensating device for catenary and additional wire compensation anchoring, which can completely replace the ordinary 1:3 ratchet compensation device, and can be used for additional wire compensation anchoring to solve the problem in windy areas. Insufficient travel of the pendant due to excessive wire expansion of the additional wire

Embodiment Construction

[0044] The present invention will be described in detail below in combination with specific embodiments.

[0045] The catenary of electrified railways generally adopts full compensation design, and gravity compensation is mostly used for anchoring. Because the ratchet compensation device has compact structure, high strength, high compensation efficiency, high reliability and braking function, it is mostly used on electrified railways and high-speed rails. use.

[0046] The additional wires in the catenary system generally adopt non-constant tension design (no compensation), but in the windy area, especially in the windshield section, the large swing of the additional wire seriously affects the safety of driving operation, so the full (half) compensation design is also adopted , The terminal adopts a ratchet compensation device. The transmission ratio of the ordinary ratchet compensation device is 1:3, but the additional wire has a large expansion, and the travel space of the ...

Abstract

The invention relates to a 1:2 type triangular tooth ratchet compensating device for a catenary and an additional wire compensating anchor. A compensation rope of an ordinary ratchet compensation device is fixed on a ratchet body as a single rope and a single or double-lug wedge clip, and is easy to fall off or not fixed into a groove. The long-term use of the ordinary ratchet compensation device results in security risks. A double-sided plate ratchet support of the 1:2 type triangular tooth ratchet compensating device comprises two opposite and parallel side plates. Each side plate is connected with a triangular integral connecting arm. A vertex of the triangular integral connecting arm is connected to the side plate through a twin shaft; the second vertex is connected to the side plate through a limiting shaft, a fixing hole of a limiting shaft is an arc-shaped slotted hole; the third vertex is connected with a ratchet assembly through a ratchet shaft. The bottom of the side plate is welded with a brake block. The 1:2 type triangular tooth ratchet compensating device can adjust itself according to the force direction of the wire and the length of linear expansion, has the function of free compensation along with the temperature change, ensures the constant tension of the catenary or the additional wire, and has the braking function under line breaking conditions so as to improve the reliability.

Description

technical field [0001] The invention relates to the technical field of electrified railway catenary, in particular to a 1:2 type triangular tooth ratchet compensation device for catenary and additional wire compensation anchor. Background technique [0002] The transmission ratio of the catenary ratchet compensator for ordinary electrified railways is 1:3. The outgoing line of the large wheel is a single compensation rope, single and double ear wedge-shaped clamps, a single roller groove, the end face is inclined (straight) tooth type, and the brake adopts a single inclined plate. The 1:3 ratchet compensation device is more difficult to use in the section where the vertical space of the pillar is limited, and the stroke of the weight is insufficient. The single compensating rope and the single grinding groove of the common ratchet device may easily cause the mutual rolling between the ropes, which may cause the friction and wear of the compensating rope, broken wires and str...
