Problems solved by technology
[0005] The technical problem to be solved by the present invention is to provide a double-wire anti-twist ratchet compensator, which can solve the problem that the existing ratchet is easy to rotate and scatter when the compensating rope is in use, causing the core wire to be broken and protrude outward under force.

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:
[0021] Such as image 3 , Figure 4 with image 3 The present invention shown includes a ratchet body 1 and a compensating rope 2 wound on the ratchet wheel body 1. The wheel groove 3 of the ratchet wheel body 1 is located in the middle groove and is provided with two wedges side by side along the width direction of the wheel groove. Hole 4, first insert the two ends of the compensation rope 2 into the two wedge holes 4 respectively, and fix them by the wedge 5, and then wind the remaining rope segments from the middle channel to the two side channels at the same time, and wind them around the outer sides of the wheel groove 3 A balance wheel 6 is connected to the center point where the compensation rope section in the channel extends to the lower part of the ratchet wheel body. The diameter of the balance wheel is equal to the width of the ratchet wh...

The invention discloses a double-wire anti-torsion ratchet wheel compensation device, and relates to the technical field of electrified railway contact network power supply devices. The double-wire anti-torsion ratchet wheel compensation device comprises a ratchet wheel body and a compensation rope wound on the ratchet wheel body, a wheel groove of the ratchet wheel body is provided with two wedge holes side by side in a middle groove channel along the width direction of the wheel groove; the two ends of the compensation rope are inserted into the two wedge holes respectively and are fixed by wedges, other rope sections are wound towards groove channels on the two sides from the middle groove channel at the same time, the compensation rope sections wound in the groove channels on the two sides of the wheel groove extend towards the lower portion of the ratchet wheel body and are connected with a balance wheel, and the diameter of the balance wheel is equal to the width of the wheel groove of the ratchet wheel. Compared with the prior art, a single-compensation-rope mode is changed into a double-compensation-rope mode, the ratchet wheel is evenly stressed, the eccentric wear phenomenon is avoided, the scattering force of the double-compensation-rope is just mutually balanced and offset, and therefore the phenomena that a falling lump rotates and a mouse tail is caused due to the fact that an outer-layer steel wire of the steel wire rope stretches and scatters are avoided.
Description
technical field [0001] The invention relates to the technical field of catenary power supply devices for electrified railways, in particular to a double-wire anti-rotation ratchet compensation device. Background technique [0002] Electrified railway is mainly composed of electric locomotive and traction power supply device, which is generally divided into two parts: traction substation and catenary. The function of the catenary is to transmit the high-voltage electricity on the catenary to the electric locomotive through the direct contact between the contact suspension and the pantograph of the electric locomotive. Tension compensation is applied at both ends of the catenary. Existing compensation devices generally include spring compensation devices, pulley compensation devices, and ratchet compensation devices. Pulley compensation devices are commonly used in normal-speed railway catenary systems, and ratchet compensation devices are generally used in high-speed railway...
