The invention provides an anti-collision traffic command booth capable of lifting the traffic policeman when being collided by a vehicle, which solves the problem that the existing traffic sentry box has poor safety protection effect on the traffic policeman.

The above technical problems are solved by the following technical solutions: an anti-collision traffic command booth, including a manned platform, a pressurized cylinder, a lifting cylinder and a base located under the manned platform, and the front, rear, left, and right sides of the base are provided There is a safety board, the safety board is horizontally and telescopically connected to the base through the booster cylinder, the manned platform is connected to the base in a liftable manner through the lifting cylinder, and the booster The cylinder includes a booster cylinder connected with the base and a booster piston located in the booster cylinder, the booster piston is connected with the safety plate through a push rod, and the lift cylinder includes a lift The cylinder and the lifting piston located in the lifting cylinder, the lifting piston is connected with the manned platform through the lifting rod, and the boosting cylinder is located in the space on the side of the boosting piston away from the safety plate It communicates with the space of the lift cylinder below the lift piston. During use, fill gas or liquid in pressurization cylinder body and lifting cylinder body, when vehicle bumps into the present invention, vehicle hits insurance plate at first, pushes booster piston by push rod in the process of insurance plate moving The movement in the pressure cylinder increases the pressure of the booster cylinder in the space where the booster piston is far away from the safety plate, and the pressure is transmitted to the lift piston, which makes the lift piston rise, and the lift piston lifts the load through the lift rod. The loading platform is lifted to prevent the traffic policeman standing on the loading platform from being hit by the vehicle.

Preferably, the push rod is provided with a shear energy-absorbing pin, and the booster cylinder or the base is provided with a stopper that cooperates with the shear energy-absorbing pin. When the safety plate is collided and pushes the push rod into the pressurized cylinder, the stopper blocks the shearing energy-absorbing pin and shears the shearing pin. When the shearing energy-absorbing pin is sheared, the collision energy is consumed, thereby reducing The energy transmitted to the base provides better protection.

Preferably, the surface of the shear energy-absorbing pin is provided with a shear guide groove, and the shear guide groove and the stopper are located on the same plane. When a collision occurs, the shear energy-absorbing pin can be accurately cut according to the predetermined position, so as to avoid the broken part of the shear energy-absorbing pin caused by the inaccurate shearing position from blocking or bending the push rod, so that the loading platform cannot be lifted reliably.

Preferably, the shear energy-absorbing pin is detachably connected with the push rod. After the vehicle body collides, the shear energy-absorbing pin can be replaced conveniently, so that other components of the present invention can be reused to the greatest extent.

The oil storage tank includes at least two cavities that are sheathed in sequence and fixedly connected together. The lower side wall of the cavity is provided with an oil outlet, and the oil outlet is sealed and connected with a sealing film. The membrane rupture rod extends vertically and is located below the oil storage tank, the membrane rupture rod and the oil outlets of all the cavities are located on the same vertical line, and the corrosive liquid storage tank is provided with regular The rot-permeable buoy, the regular rot-permeable buoy includes a corrosion-resistant shell with an open lower end and several partitions that can be corroded by the corrosive liquid in the corrosive liquid storage tank for a set period of time, and the partitions will The shell is divided into several floating chambers, the number of which is equal to the number of the cavities, the partitions are distributed along the up and down direction, and the oil storage tank is floated in the corrosive liquid storage tank by the buoy Each of the floating chambers can independently float the oil storage tank on the corrosive liquid; every time the corrosive liquid in the corrosive liquid storage tank corrodes a floating chamber and causes the oil storage tank to drop once, the The membrane rupture rod can only pierce the sealing membrane on one cavity. It can carry out regular self-lubrication on the lifting rod to prevent the lifting rod from being unable to move, and the reliability is good.

As a preference, one of the oil storage tank and the corrosive liquid storage tank is connected with a guide rod extending in the vertical direction, and the other is connected with a guide sleeve sleeved on the guide rod, and the oil inlet bucket and the The corrosive liquid storage tanks are fixed together. It can effectively prevent the phenomenon that the oil storage tank shakes in the horizontal direction during the descending process of the oil storage tank, which causes the rupture rod to fail to puncture the sealing membrane. Improved reliability when breaking membranes. It can prevent the relative movement between the rupture rod and the corrosive liquid storage tank along the up-and-down direction, resulting in the phenomenon that the rupture rod accidentally punctures the sealing membrane.

Preferably, the corrosive liquid storage tank is provided with a corrugating plate that can float on the corrosive liquid in the corrosive liquid storage tank, and the outer casing can pass through the corrugating plate in a vertical direction. During use, when the corrosive liquid storage tank is vibrated, the corrosive liquid will slosh. The waves generated by the corrosive liquid slosh will cause the regular decay buoy to rise and fall. If the lifting phenomenon is too large, the membrane rupture rod will puncture the seal. The phenomenon that the lubricating oil flows out before the set time is not reached, that is, the malfunction caused by vibration. After the wave suppressing plate is installed, it can effectively reduce the lifting range of the periodic decay buoy caused by vibration, and avoid malfunction caused by vibration.
