Problems solved by technology

Therefore, when the rail flat car is running in an inflammable and explosive environment or transporting flammable, explosive, corrosive and toxic materials, when it derails, the front and rear rail flat cars collide, the remote control system fails, and the braking system fails In the event of a collision, it is very easy to cause damage to the electrical equipment on the vehicle, resulting in leakage or sparks, causing fire or explosion, or causing leakage or explosion of dangerous goods loaded, etc.

Embodiment 1

[0012] refer to figure 1 , this embodiment includes a bumper 1, a damping spring I2-1, a damping spring II2-2, a bracket 3, a piston I4-1, a piston II4-2, an air chamber I5-1 and an air chamber II5-2; the bumper 1 There are guide wheels on it ( figure 1 not shown), the air chamber I5-1 is provided with a one-way valve I8-1, and the air chamber II5-2 is provided with a one-way valve II8-2; the damping spring I2-1 and the damping spring One end of II2-2 is respectively connected with the bumper 1, and the other end is connected with the bracket 3; the piston I4-1 is located in the air chamber I5-1, and the piston II4-2 is located in the air chamber II5-2, and respectively pass through Piston rod links to each other with bracket 3.

[0013] When this embodiment is applied to a remote-controlled rail flat car, the bumper 1 is installed on the front or rear of the rail flat car, and other parts are installed on the bottom of the rail flat car; the bracket 3 is connected to the mo...

Embodiment 2

[0016] The difference between this embodiment and Embodiment 1 is that an air compression mechanism is provided at the end of the air chamber with a valve.

[0017] Usually, the air chamber is provided with a relatively high pressure gas (far less than the critical opening pressure of the valve). At this time, under the condition of attenuating the same impact energy, the required volume of the air chamber is greatly reduced, which is beneficial to the arrangement, or in the The attenuation efficiency and the total impact energy that can be attenuated can be improved under the same volume of the air chamber.

Abstract

The invention discloses an anti-explosion and anti-impact bumper system of a remote-control rail flat car. The system comprises a bumper, a damping spring, a bracket, a piston and an air chamber, wherein a guide rail wheel is arranged on the bumper; a check valve is arranged on the air chamber; one end of the damping spring is connected with the bumper and the other end is connected with the bracket; and the piston is positioned in the air chamber and is connected with the bracket through a piston rod. The anti-explosion and anti-impact rear bumper system is simple in structure, is convenient to operate simply and can effectively reduce the probability of explosion or fire caused by damage of electric appliance equipment in a combustible and explosive environment or leakage of vehicle-carried dangerous goods.

Description

technical field [0001] The invention relates to an explosion-proof and impact-proof bumper system for a remote-controlled rail flat car. Background technique [0002] In the existing remote-controlled rail flat car, there is no device for reducing the impact energy at the front and back of the general flat car. Therefore, when the rail flat car is running in an inflammable and explosive environment or transporting flammable, explosive, corrosive and toxic materials, when it derails, the front and rear rail flat cars collide, the remote control system fails, and the braking system fails In the event of a collision, it is very easy to cause damage to the electrical equipment on the vehicle, resulting in leakage or sparks, causing fire or explosion, or causing leakage or explosion of dangerous goods loaded. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an explosion-proof and impact-proof bumper system for remote-...
