Channel rail expansion adjustor

Abstract

The invention discloses a channel rail expansion adjustor. A gap L is arranged between two butted channel rails, the channel rail expansion adjustor comprises a box, a clamping plate A, a clamping plate B, cover plates, a rail brace and a rail brace distance adjustment block, the clamping plate A is arranged at the outer side of the joint between the channel rail A and the channel rail B, and the clamping plate B is arranged at the inner side of the joint between the channel rail A and the channel rail B; the rail brace is shaped like an L, the vertical section of the L is in contact with the clamping plate A, and the horizontal section of the L is fixed at the inner side of the bottom plate of the box through the rail brace distance adjustment block; the ends of the butted section of the channel rails are provided with transversely through slotted holes, horizontal bolts sequentially run through the clamping plate B, the slotted holes of the channel rails, the clamping plate A and the rail brace and are then fixed, and the butted section of the channel rails, the clamping plate A, the clamping plate B, the rail brace and the rail brace distance adjustment block are arranged in the box. The channel rail expansion adjustor is used on a channel rail line to implement the function of expanding and contracting rails and adjusting rail distance; meanwhile, the channel rail expansion adjustor also can meet the requirement of burying channel rails into the ground.

Description

technical field [0001] The invention relates to a rail telescopic adjuster, in particular to a telescopic adjuster suitable for grooved rails in modern tramway lines, and belongs to the technical field of urban rail transit. Background technique [0002] At present, trams have been gradually developed as urban rail transportation tools, and seamless lines with low vibration and noise and less line maintenance are an inevitable trend. When the track is laid on the bridge surface, due to the use of seamless lines, due to temperature changes, vehicle loads, etc., there will be relative displacement between the beam body and the track, which will lead to additional force on the beam rail and change the bridge’s bearing capacity. When the additional force of the beam rail increases and the force on the track and bridge is bad, it is necessary to use a rail telescopic regulator to adjust the expansion and contraction of the rail. [0003] The existing tram tracks mainly use I-s...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a telescopic regulator for grooved rails, which solves the problem that the existing grooved rail track line has no telescopic device, and the technology that the conventional rail telescopic device such as the telescopic device of the I-shaped rail cannot achieve the expected effect of the grooved rail problem, thereby effectively solving the problems existing in the above-mentioned prior art
