Detailed Description
The features of the utility model and other related features are described in further detail below by way of example in conjunction with the following figures to facilitate understanding by those skilled in the art:
as shown in fig. 1-3, the labels 1-13 are shown as: the hydraulic buffer device comprises a guide impact device 1, a hydraulic buffer 2, a main fixed support 3, an auxiliary fixed support 4, an anchor bolt 5, an anchor bolt 6, a hexagonal bolt 7, a steel rail 8, a locking device 9, a car bumper base 10, a guide impact part 11, a guide impact support 12 and a buffer energy absorption pad 13.
Examples: as shown in fig. 1 to 3, the stopper for track traffic in this embodiment is installed at the end of a rail 8 of a track traffic route, and is used for braking a track traffic train, so as to prevent the track traffic train from being flushed out of the route due to an accident.
As shown in fig. 1 to 3, the main body of the rail transit vehicle stopper in the present embodiment mainly includes a guide striking device 1, a hydraulic buffer 2, a main mount 3, an auxiliary mount 4, and a bumper base 10.
The guiding and impacting device 1 comprises a guiding and impacting part 11 and a guiding and impacting bracket 12, wherein the guiding and impacting part 11 is arranged at the middle position of the guiding and impacting bracket 12 and is consistent with the height of a car coupler at the head position of a rail transit train. When the train hits the guiding and impacting device 1, the coupler at the head position of the train hits the guiding and impacting part 11 in advance, so that the train body of the train is prevented from being damaged. The guide impact bracket 12 is clamped and connected on the steel rail 8 through the locking device 9, and the locking device 9 and the steel rail 8 can be in communication sliding fit, so that the guide impact device 1 can slide along the steel rail 8; when a train hits the guide percussion device 1, the guide percussion device 1 slides toward the bumper base 10 by impact energy.
Two sets of hydraulic buffers 2 are connected to the rear of the guiding and impacting device 1, and each set of hydraulic buffers 2 is fixedly arranged on the surface of a car bumper foundation 10 through a main fixed support 3 and an auxiliary fixed support 4. In the present embodiment, the main fixing support 3 and the auxiliary fixing support 4 are connected by arranging anchor bolts 6 buried in the fender base 10. The main fixing support 3 and the auxiliary fixing support 4 are arranged at a certain interval distance to fix different positions of the hydraulic damper 2, ensuring that the hydraulic damper 2 can be firmly fixed on the bumper base 10 and is finally stressed by the bumper base 10.
The hydraulic telescopic rod bodies of the two groups of hydraulic buffers 2 respectively extend out of the range of the vehicle bumper foundation 10 in an overhanging manner and are connected with the guiding impact device 1; when the guiding impact device 1 slides along the steel rail 8 under impact energy, the guiding impact device 1 pushes the hydraulic telescopic rod of the hydraulic buffer 2 to retract towards one side of the car bumper foundation 10, and at the moment, the hydraulic buffer 2 can absorb the impact energy to realize braking of the rail transit train.
In this embodiment, the two hydraulic telescopic rods are symmetrically arranged along the center line of the rail transit line, so as to ensure uniformity of the guiding impact device 1 in absorbing impact energy, and avoid damage caused by uneven stress.
As shown in fig. 1, the rail 8 extends into the bumper foundation 10, that is, the bumper foundation 10 embeds a part of the rail body at the end of the rail 8 and forms an integral stress structure during operation. When the rail transit train hits the car stopper, the car stopper base 10 pulls the steel rail 8, and the steel rail 8 can give the car stopper base 10 a counter force, so that the resistance of the car stopper is increased.
The embodiment is implemented in specific manner: the bumper foundation 10 can be a reinforced concrete foundation, and when the bumper foundation is applied, the bumper foundation 10 and the lower foundation can be connected into a whole by implanting expansion anchor bolts in the bumper foundation, so that the stress capacity of the bumper foundation 10 is increased, and the safety is improved.
As shown in fig. 3, a buffer energy absorbing pad 13 can also be symmetrically arranged on the guiding and impacting device 1, and the arrangement position of the buffer energy absorbing pad 13 corresponds to the impacting position when the train body of the rail transit train impacts the guiding and impacting device 1 so as to protect the train body. The cushion energy absorbing pad 13 may be made of a flexible material.
Although the foregoing embodiments have been described in some detail with reference to the accompanying drawings, it will be appreciated by those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the utility model as defined in the appended claims, and thus are not repeated herein.
