Surely there is the barrel chamber 41 extended along the longitudinal direction, the front end of barrel chamber 41 is equipped with front apron 42, and front apron 42 is equipped with first through hole 421,
The rear end of barrel chamber 41 is equipped with rear baffle 43, and rear baffle 43 is equipped with the second through-hole 431；Compression bar rear end 32 is protruded into from first through hole 421
In barrel chamber 41 and compression bar 3 can slide along the longitudinal direction；Guide rod 5 has guide rod front end 51 and guide rod rear end 52 along the longitudinal direction, leads
Bar 5 is slidably disposed through the second through-hole 431 along the longitudinal direction, and guide rod front end 51 is protruded into barrel chamber 41, and guide rod rear end 52 is located at
Outside barrel chamber 41；First spring 6 is located in barrel chamber 41 and is mounted on guide rod 5, and the front end of the first spring 6 and guide rod 5 are fixed, so that
Compression bar rear end 32 is in contact with guide rod front end 51, and the rear end of the first spring 6 is withstood on the leading flank of rear baffle 43；Pre-tightening apparatus position
In the rear side of rear baffle 43, pre-tightening apparatus is connected with guide rod 5, so that the first spring 6 generates pretightning force.
Specifically, recessed ball pad 1 has concave spherical surface 11, recessed ball pad 1 is used to be mounted on the leading flank on car head；Convex ball
Pad 2 has the convex spherical 21 matched with concave spherical surface 11；Compression bar 3 has compression bar front end 31 and compression bar rear end 32 along the longitudinal direction,
Compression bar front end 31 is fixed with convex ball pad 2.As a result, when station is surprisingly rushed in the brake failure of the trolley coach such as cableway, cable car, it is mounted on visitor
The recessed ball pad 1 of anticollision device, collision-prevention device on vehicle first hits the convex ball pad 2 in standing on the compression bar 3 of car buffer 100, car collision side out of control
To uncertain, concave-convex mating spherical surfaces are formed by the concave spherical surface 11 of recessed ball pad 1 and the convex spherical 21 of convex ball pad 2, can be born multi-party
To shock loading, make impact force along the compression bar 3 of car buffer 100 axial direction (i.e. shown in attached drawing 1 in the front-back direction to
Rear direction) transmitting.
Sleeve 4 defines the barrel chamber 41 extended along the longitudinal direction, and the front end of barrel chamber 41 is equipped with front apron 42, and front apron 42 is set
There is first through hole 421, the rear end of barrel chamber 41 is equipped with rear baffle 43, and rear baffle 43 is equipped with the second through-hole 431；Compression bar rear end 32 is from
One through-hole 421 protrudes into barrel chamber 41 and compression bar 3 can slide along the longitudinal direction；Guide rod 5 has 51 He of guide rod front end along the longitudinal direction
Guide rod rear end 52, guide rod 5 is slidably disposed through the second through-hole 431 along the longitudinal direction, and guide rod front end 51 is protruded into barrel chamber 41, is led
Rod rear end 52 is located at outside barrel chamber 41；First spring 6 is located in barrel chamber 41 and is mounted on guide rod 5, the front end of the first spring 6 with lead
Bar 5 is fixed, so that compression bar rear end 32 is in contact with guide rod front end 51, the rear end of the first spring 6 withstands on the leading flank of rear baffle 43
On.The radial displacement of the first spring 6 can be limited by barrel chamber 41 as a result,.Pass through the first through hole 421 on front apron 42, side
Just compression bar 3 protrudes into barrel chamber 41, can be in contact with compression bar 3, and compression bar 3 can be not only supported by front apron 42, limits compression bar 3
Radial displacement, and can also limit the first spring 6 front end and guide rod front end 51 from the front end of barrel chamber 41 stretch out.Pass through rear gear
The second through-hole 431 on plate 43 can be convenient guide rod 5 and move along the longitudinal direction, not wait you can be with support guide rod by rear baffle 43
5, the radial displacement of guide rod 5 is limited, and the rear end that can also limit the first spring 6 is stretched out from the rear end of barrel chamber 41.As track visitor
When vehicle surprisingly rushes station, compression bar 3 is moved backward by the effect of impact force, and guide rod 5 also moves backward, the mistake that guide rod 5 moves backward
Along guide rod 5 elastic compression occurs for the first spring 6 in journey, absorbs Impact energy by 6 elastic compression of the first spring, therefore, the
One spring 6 plays the role of buffer shock-absorbing, is effectively reduced the sharp impacts of car, protects the safety of personnel and equipment.
After compression bar 3 is disappeared by impact force, the first spring 6 can drive guide rod 5 to reset together.
