Problems solved by technology

[0003] The content of the present invention is to solve the problem that there is no automatic wheel stop and anti-slip device specially designed for vehicles staying in passenger technology stations and passenger garages at home and abroad. The domestic wheel stop top has a complicated structure and a long shell length. The top needs to destroy the cement foundation, which affects the safety of the driving operation, and then it is necessary to provide a wheel stop top for railway passenger garages and passenger technical stations.

Abstract

The invention discloses a scotch block jack for a passenger train garage and a passenger station of a railway, and relates to speed retarders. The scotch block jack solves the problems that nowadays,there is no automatic scotch block slip prevention equipment specially designed for trains parked in the passenger station and the passenger train garage at home and abroad, scotch block jacks designed at home have complicated structures and shells with long strengths, cement foundations need to be damaged when existing scotch block jacks are installed, and the operation safety of driving trains is influenced. The scotch block jack comprises a shell assembling part, a sliding oil cylinder assembling part and a buffer stop structure; the sliding oil cylinder assembling part comprises a piston rod, a pressure valve outer spring, a pressure valve inner spring, a clamping spring, a return stroke valve plate, a pressure valve rod, a pressure valve base, a one-way valve adjusting screw, a one-way valve steel ball, a sliding oil cylinder and a sealing assembly; a spring installing blind hole is machined in the top of the piston rod, the pressure valve outer spring and the pressure valve innerspring are arranged in the spring installing blind hole of the piston rod, and the pressure valve outer spring sleeves the pressure value inner spring. The scotch block jack is applied to occasions of the passenger train garage and the passenger station.

Description

technical field [0001] The invention relates to a deceleration top, in particular to a stopper top used for railway passenger garages and passenger technical stations. Background technique [0002] At present, there is no automatic wheel stop and anti-slip device specially designed for parking vehicles in passenger technical stations and passenger garages both at home and abroad. At present, anti-slip iron shoes are still used in the warehouse to stop the wheels and prevent slippage. This method is very backward, and there are cases where iron shoes are missing, causing accidents. And although domestic existing TDJGST-202 type wheel stopper, TDJT-102 type wheel stopper also can satisfy the function of wheel stopper anti-slip, but the structure of these two kinds of tops is complicated, and the shell length is very long. There is basically no distance between the cement foundation and the rail bottom in the passenger garage. If the existing type of wheel stopper is installed...
