Abstract

The invention discloses a noise reduction type C-shaped contact rail supporting device which comprises a clamping head mechanism, a mounting mechanism, a locking mechanism and an insulating mechanism, and the mounting mechanism is arranged at one end of the insulating mechanism; the clamping head mechanism is provided with a clamping head assembly, the length of the long side of the clamping head assembly is larger than the height of the notch of the C-shaped contact rail, and the length of the short side of the clamping head assembly is smaller than the height of the notch of the C-shaped contact rail. The clamping head mechanism has a first state and a second state. When the clamping head mechanism is in the first state, the long edge of the clamping head assembly is perpendicular to the groove height direction of the C-shaped contact rail. When the clamping head mechanism is in the second state, the long edge of the clamping head assembly is parallel to the groove height direction of the C-shaped contact rail; the locking mechanism is arranged on the mounting mechanism and movably connected with the clamping head mechanism so as to be used for locking the clamping head mechanism to be in the first state or the second state. The device can be in self-adaptive contact with the machining error size of the C-shaped groove of the strand rail body, zero-clearance fit supporting of the rail body is achieved, and the phenomenon that the clamping head assembly swings and deviates from a working position in the using process can be avoided.

Description

technical field

[0001] The invention relates to the technical field of rail transit C-shaped contact rail insulation support, in particular to a noise-reducing C-shaped contact rail support device. Background technique

[0002] In the field of rigid contact rail side moving contact current-supply power supply technology represented by Changsha Maglev Express Line, the C-shaped contact rail is easy to achieve high contact rail installation accuracy with appropriate side stiffness, and the rear part of the C-shaped rail The C-shaped groove is used as the installation support point of the C-shaped contact rail, which makes the cross-sectional size of the charged body of the contact rail small, which is conducive to reducing the installation space size requirements of the contact rail. Compared with the I-shaped rail, the C-shaped contact rail has technical advantages. However, the maglev train lines such as the Changsha Maglev Express Line still have noise from shoe-rail contac...
