Description

Technical Field

[0001] The utility model relates to the technical field of track car stoppers, in particular to a composite damping car stopper. Background Art

[0002] A car stopper is a specially designed device used to safely stop and stop vehicles or mobile equipment on rail tracks or in industrial environments. This car stopper combines multiple technologies and materials to provide greater effectiveness and safety.

[0003] The main feature of a car stopper is its ability to absorb and disperse the energy generated during an impact, thereby reducing damage to the vehicle and the car stopper itself. This is usually achieved by using a special hydraulic structure design or using energy-absorbing materials. Car stops that use hydraulic structures to absorb energy have a short service life due to the risk of oil and air leakage and require frequent maintenance. Car stops that use energy-absorbing materials are directly exposed to the air and are prone to aging, so they also need to be replaced frequently. In addition, although traditional car stops frequently come into contact and compression with rail vehicles, they cannot monitor the magnitude of their reverse thrust, which may cause damage to the vehicle.

A buffer cavity 111 opening outward is provided in the inner cylinder tube 102. A movable piston 112 capable of telescopic movement is provided in the buffer cavity 111. A telescopic outer cylinder tube 103 is sleeved on the outer end face of the inner cylinder tube 102. An energy absorption cavity 113 opening toward the buffer cavity 111 is provided in the outer cylinder tube 103. A steel structure plate 104 is fixedly provided on the top of the outer cylinder tube 103.

[0026] It should be noted that the installation base plate 101 is installed on the reinforced concrete wall in the rail station to play the role of positioning and blocking the car.

[0027] It should be further explained that a damping fluid is provided in the buffer chamber 111 and a reset system is provided in the inner cylinder tube 102 , which can drive the outer cylinder tube 103 to reset and move.

[0028] Furthermore, an energy absorbing element plate 117 is fixedly provided at the top of the energy absorbing cavity 113 , and an energy absorbing buffer groove 115 is provided in the energy absorbing element plate 117 at a position in contact with the steel structure plate 104 , and the energy absorbing buffer groove 115 is filled with damping fluid to achieve energy absorbing effect.

[0029] It is worth noting that the damping compound fluid uses a specially formulated rubber combined with high-performance damping materials to provide excellent impact absorption and energy dispersion capabilities. Its composite material not only resists extreme weather conditions and chemical corrosion, but also effectively prevents rust problems in long-term use.

[0030] Furthermore, a connection groove 118 is provided at one end of the energy absorbing element plate 117 , and a mounting plate 116 is provided on the end surface of the movable piston 112 facing the energy absorbing element plate 117 .

[0031] Furthermore, a piston rod 106 is installed between one end surface of the movable piston 112 and one end surface of the energy absorbing element plate 117. Both side end surfaces of the piston rod 106 are respectively installed in the connecting groove 118 and the mounting plate 116. Mounting gaskets are provided between both ends of the piston rod 106 and the mounting plate 116 as well as the connecting groove 118 to achieve a stable installation effect.

[0032] It should be further explained that a sealing gasket is provided between the movable piston 112 and the inner wall of the buffer chamber 111 .

[0033] Furthermore, a pressure detector 114 is provided in a side wall of the energy absorption buffer groove 115 , and the pressure detector 114 is used to detect the vehicle-blocking impact force received in the energy absorption buffer groove 115 .

[0034] Furthermore, a pressure sensor 109 is fixedly disposed in the mounting base plate 101 , and a signal transmitter 110 is disposed on one side of the pressure sensor 109 for signal communication.

[0035] It should be noted that the pressure sensor 109 is a pressure sensor in the prior art, and the signal transmitter 110 is a signal transmitter.

[0036] like Figure 6 As shown, the second embodiment of the utility model is the same as the device of the first embodiment, except that a track positioning fixture 120 that can move and fix the position in the track is provided, and a fixed support plate 119 is fixed on one end face of the track positioning fixture 120. The mounting base plate 101 can be mounted on one end face of the fixed support plate 119, thereby enabling the vehicle to be blocked at different positions in the track.

[0037] When using this solution, first drive the installation base plate 101 to move as a whole to the working position, and after the steel structure plate 104 is facing the working position of the track stopper, the installation base plate 101 is installed as a whole to the end of the track or the designated track installation area, and according to the working position of the stopper, the extension length of the outer cylinder tube 103 is set, and the steel structure plate 104 is facing the working direction of the track stopper.

[0038] When the rail transit vehicle blocking work is carried out, as the rail transit vehicle contacts and resists the top of the steel structure plate 104, the damping composite liquid in the energy absorption buffer groove 115 plays a preliminary energy absorption buffering effect, and the pressure detector 114 performs pressure detection, and as the steel structure plate 104 subsequently blocks the vehicle and pushes the moving piston 112 to move, the damping composite liquid in the buffer chamber 111 plays a further energy absorption buffering effect, and the pressure sensor 109 performs a pressure detection effect on the mounting base plate 101, and the signal transmitter 110 outputs the working data of multiple vehicle blocking operations, and through the Internet of Things technology, the multiple signals are centrally collected and a signal data model is established.

[0039] Then, during the subsequent car-blocking operation, through the established signal data comparison, the reset system can be used in advance to change the extension and contraction degree of the outer cylinder tube 103, extend the car-blocking distance of the steel structure plate 104, and improve the stability of the car-blocking operation. At the same time, by adopting damping composite materials, the car-blocking device can maintain its physical and functional properties for a long time, significantly reducing the replacement frequency and maintenance costs.

[0040] At the same time, the device can be installed as a whole on one side end surface of the fixed support plate 119, and moved and positioned at a certain place on the track through the track positioning fixture 120, so as to realize the subsequent track internal vehicle buffering work.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
