Description
Technical Field
The invention relates to the technical field of C-shaped contact rail insulation support of rail transit, in particular to a noise reduction type C-shaped contact rail support device.
Background
In the technical field of rigid contact rail side moving contact current-donating power supply represented by a long sand magnetic suspension fast line, the C-shaped contact rail is easy to realize higher contact rail installation accuracy with proper side rigidity, and a C-shaped groove at the rear part of the C-shaped rail is used as an installation supporting point of the C-shaped contact rail, so that the cross section size of a charged body of the contact rail is small, and the requirement on installation space size of the contact rail is favorably reduced; the C-shaped contact rail has technical advantages over the i-shaped rail. However, when the train runs along a magnetic levitation train line such as a Changsha magnetic levitation express line, the noise generated by the contact of boot rails also exists, the magnetic levitation train supports the train to run by magnetic force, and the low noise is a big selling point; the noise is generated when the current receiving sliding shoes of the vehicle-mounted current collector pass through the rail gap of the power supply rail, the noise is caused by the impact of rail bodies on two sides of the rail gap, the noise is related to the height difference of rail surfaces on two sides of the rail gap and is also related to a rail supporting structure, the vibration of the rail bodies caused by the impact of the shoe rails when the shoe rails pass through the rail gap due to the height difference of the rail surfaces is a source of impact vibration noise, the higher the vibration frequency is, the farther the distance of the propagation of the vibration noise is, the longer the aftervibration time is, the longer the noise time is, and the vibration frequency and the attenuation speed of the contact rail are related to the supporting structure of the contact rail.
The existing C-shaped rail supporting structure of the magnetic levitation express line is described in detail in patent application No. CN201810020284.9, and the structure is mainly characterized in that a C-shaped rail is clamped by a clamping piece and a limiting piece which are connected in series with a screw rod screwed with an insulator and extend into a C-shaped groove of a rail body and are fastened by nuts, and the clamping tightness is adjusted by an addition and subtraction gasket with low efficiency; the rail body is an extruded section, errors exist in a C-shaped groove and a wall thickness of the rail body, gaps among the clamping pieces, the limiting pieces and the rail body must guarantee the maximum wall thickness and the minimum C-shaped rail body groove width, the rail body can freely stretch and slide under thermal expansion and cold contraction, gaps exist among the clamping pieces, the limiting pieces and the rail body at all supporting points and are uneven, so that the installation precision of the contact rail is difficult to improve, vibration damping of all supporting points on the rail body is very small, and the existence of the supporting gaps can cause impact noise between the rail body and the supporting point clamping pieces even if the contact rail is not at the rail gap and when a current-receiving sliding shoe of the vehicle-mounted current collector passes through all supporting points during high-speed operation; in addition, the clamping piece of the structure does not have a locking structure which rotates relative to the insulator, so that after the clamping piece runs for a long time, the clamping piece is gradually pushed to rotate to deviate from the working position of the clamping piece in the cyclic extension and retraction of the contact rail, and even the T-shaped clamping piece can deflect to the horizontal position from the vertical supporting position under the action of impact vibration in severe cases, so that the rail body is completely unsupported.
