Description
Technical field
The utility model relates to a kind of hydraulically driven anticollision car stop that is used for places such as parking lot, expressway tol lcollection place.
Background technology
Hydraulically driven car stop has stable drive, reliability advantages of higher.Typical hydraulically driven car stop as shown in Figure 1.This car lug comprises a hydraulic system, a main shaft assembly 11, a pin assembly 12, a hydraulic cylinder assembly 1, a buffer 13 and a connecting rod 14.Buffer 13 generally includes another oil cylinder 13 " and a spring 13 '.
The hydraulic oil pipe system of this car lug as shown in Figure 4.Comprise described fuel tank 9, described motor 6, described oil pump 5 and a three position four-way electromagnetic valve 3 in this oil circuit, oil pump 5 connects with three position four-way electromagnetic valve 7 by two branch roads, and an overflow valve 4 is set on the branch road, and an one way valve 3 is set on another branch road.In addition two interfaces of three position four-way electromagnetic valve 7 again by two one-way throttle valves 2 respectively with two oil cylinders 1 and 13 " in one connect.
The shortcoming of this car lug is as follows: at first, the locking poor-performing of pin, when pin remain on for a long time vertically and level between the centre position time because oil leaks, pin is reduced gradually; Secondly, if occur having a power failure when pin is horizontal, then pin can't be got back to vertical release position.
Another shortcoming of traditional car lug is the motion that can only do in a vertical plane between above-mentioned horizontal level and the stand up position.It is found that, vehicle lance incident in use often occurs, or this is because the driver is careless, perhaps causes owing to the driver has a mind to steal a ride.Because the pin of above-mentioned traditional car lug relative car lug support body perfect rigidity in horizontal plane is fixed, promptly, in this horizontal plane without any freedom of motion, so, during lance not only pin be damaged, and pin passes to bearing with vehicle effect moment thereon, makes bearing also be subjected in various degree damage, heavy then complete machine is scrapped, and gently then needs long time and expense place under repair.
In order to reduce the loss that lance causes, the someone has designed a kind of car lug with the bending resistance spring.U.S. Pat 4227344 discloses the such car lug of an example.Fig. 7 and Fig. 8 are respectively that one in this patent overlooked and front view.As can be seen, comprise the anticollision device, collision-prevention device of a bending resistance form of springs in this car lug from this two width of cloth figure, pin 310 is connected with bearing 314 by bending resistance spring 324.Like this, when vehicle bumped against pin 320, bending resistance spring 324 can rotate pin in horizontal plane after the power that is subjected to a certain degree, because the existence of bending resistance spring 324, vehicle is applied to the moment that the power on the pin produces on bearing 316 very little, can not damage bearing 316.
The shortcoming of this car lug is that when pin was hit, the bending resistance spring made it have bounce.Therefore, if stop behind the vehicle lance, pin can rebound, and pounds on the car, and vehicle is caused damage.If vehicle is rushed bar and escaped, the spring after the bounce-back can cause serious injury personnel.
Summary of the invention
