Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a buffer for the subway track, which effectively avoids the vertical and horizontal vibrations caused by the subway wheels running at high speed in the prior art, which will damage the inside and outside of the track. Reduce the service life of the track, the rivets and rivet holes used to stabilize the wheels will shake, making the track shake is not conducive to the operation of the wheels, the track specifications are still different, but there is no targeted stabilization equipment.

Embodiment 1

[0022] Such as Figure 1-Figure 3 As shown, the buffer used for the subway track includes a base 2, a shock-reducing device for buffering and a stabilizing device; the device for reducing the shock for buffering includes a positioning plate fixed to the inside of the base 2 4. There is a moving opening 5 in the inside of the positioning plate 4, and the inside of the moving opening 5 can be moved and connected to the fastening block 7. The upper end of the fastening block 7 is fixedly connected to the fastening strip 8, and the fastening The upper end of the bar 8 is fixedly connected to the assembly block 24, and the subway track 35 is given several levels of vertical vibration reduction, which reduces the shock performance better and reduces the shock force of the subway track 35; The positioning block 25 on both sides of the upper end of the block 24, the inside of the positioning block 25 has an adjustment port 26, the inside of the adjustment port 26 is screwed with a scr...

Abstract

A buffer for a subway rail comprises equipment for buffering and reducing shake. The equipment comprises a positioning plate fixedly connected into a base, a moving opening is formed in the positioning plate, a buckling block is movably connected into the moving opening, a buckling strip is fixedly connected to the upper end of the buckling block, and an assembling block is fixedly connected to the upper end of the buckling strip. Stabilizing equipment comprises positioning blocks fixedly connected to the two sides of the upper end of the assembling block, adjusting openings are formed in thepositioning blocks, screws used for adjusting are connected into the adjusting openings in a screwed mode, and one end of the screw used for adjusting is fixedly connected with a moving block. In combination with other structures, the defects that in the prior art, vertical and horizontal shake caused by high-speed operation of subway wheels can damage the interior and exterior of a rail, the service life of track is reduced, rivets and rivet holes used for stabilizing wheels shake, so that the tracks shake, running of the wheels is not facilitated, the specifications of the tracks are still different, and targeted stabilizing equipment does not exist are overcome.

Description

technical field [0001] The invention belongs to the technical field of subways, and also belongs to the technical field of buffers, in particular to a buffer used for a subway track. Background technique [0002] Rail transit refers to a type of vehicle or transportation system in which operating vehicles need to run on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, more and more types of rail transit have emerged, not only in long-distance land transportation, but also in short- and medium-distance urban public transportation. One common rail transit is the subway. [0003] In subway rail transit, a certain amount of impact energy will be generated during the contact process between the wheel and the track, and the impact of the generated vibration on the surrounding environment and buildings is inevitable. Existing wheels will vibra...
