DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to specific examples, but the embodiments of the present invention are not limited thereto.

[0024] Please also see Figures 1 to 4 The embodiment of the present invention discloses a suspended sliding car stop device installed inside a track beam, comprising a car stop seat 1, which is installed on the track beam; the car stop seat 1 comprises an upper cover plate 1-1 and two side plates 1-2 fixed below the upper cover plate 1-1, the upper cover plate 1-1 being slidably suspended above the track beam bottom plate 3 by friction devices 2 provided on both sides, and this method ensures that the car stop seat 1 is firmly connected to the track beam and does not fall, thereby improving safety; the outer sides of the two side plates 1-2 are provided with guide devices 4, and the guide devices 4 are in rolling contact with the longitudinal beam 5 below the track beam bottom plate 3; a hydraulic buffer 6 is fixed between the lower portions of the two side plates 1-2, and a collision head 7 is fixed to the front end of the hydraulic buffer 6. The hydraulic buffer 6 is used for buffering at the moment of collision, effectively improving the comfort and safety of the car stop collision buffering; the collision head 7 cooperates with the vehicle coupler to ensure the safety of the coupler and the vehicle when the vehicle coupler collides with the car stop.

[0025] Furthermore, four groups of guide devices 4 are provided on the outer sides of the two side panels 1-2, and the four groups of guide devices 4 are respectively close to the four corners below the upper cover plate 1-1, thereby guiding the entire vehicle stop device; three groups of friction devices 2 are respectively provided on both sides of the upper cover plate 1-1, and the friction devices 2 are located between the guide devices 4.

[0026] Furthermore, the friction device 2 includes: a friction block seat 2-1, a friction block 2-2, a connecting bolt 2-3, a disc spring 2-4 and an adjusting nut 2-5; wherein,

[0027] The friction block seat 2-1 is arranged below the upper cover plate 1-1; the friction block seat 2-1 is an L-shaped structure, one end of which is vertically fixed to the lower surface of the upper cover plate 1-1, and the other end is horizontally arranged with the upper cover plate 1-1. The connecting bolt 2-3 passes through the upper cover plate 1-1 and the friction block seat 2-1 from top to bottom, and then the disc spring 2-4 and the adjusting nut 2-5 are installed. The disc spring 2-4 is fixed between the friction block seat 2-1 and the adjusting nut 2-5 through the disc spring seat 2-6 and the disc spring pressure plate 2-7; the friction block 2-2 is symmetrically arranged on both sides of the track beam bottom plate 3, and is respectively fixed below the upper cover plate 1-1 and above the friction block seat 2-1 to clamp the track beam bottom plate 3.

[0028] In the embodiment of the present invention, two friction blocks 2 - 2 are provided on one friction block seat 2 - 1 .

[0029] The friction block 2-2 is detachable, and only the friction block 2-2 needs to be replaced when it is worn, thereby improving the economy and service life of the sliding car stop; in addition, the friction block 2-2 adopts multi-point local contact with the track beam, which can effectively reduce the precision requirements of the friction surface of the track beam and avoid changes in friction resistance due to changes in the flatness of the friction surface of the track beam.

[0030] The embodiment of the present invention adopts multiple groups of disc springs 2-4 to provide clamping force for the friction block 2-2, thereby providing buffering resistance for the vehicle stop. The multiple groups of disc springs 2-4 adopt a series-parallel combination structure, which reduces the stiffness of the disc springs 2-4 while ensuring the clamping force, thereby facilitating the precise adjustment of the friction resistance.

[0031] Furthermore, the adjusting nut 2-5 is a slotted nut, and a cotter pin 2-8 is fixed at the end of the connecting bolt 2-3. The cotter pin 2-8 is located in the slot of the slotted nut, and the slotted nut is locked by the cotter pin 2-8 to prevent the slotted nut from loosening during the use of the vehicle stopper, causing the compression amount of the disc spring 2-4 to change, affecting the buffering performance of the vehicle stopper; the compression amount of the disc spring 2-4 can be adjusted by adjusting the slotted nut to adjust the clamping force of the friction block 2-2, thereby adjusting the friction force between the friction block 2-2 and the track beam bottom plate 3; a detent plate 2-9 is provided between the connecting bolt 2-3 and the upper cover plate 1-1, and the detent plate 2-9 is fixed on the upper cover plate 1-1 to ensure that the connecting bolt 2-3 does not rotate when the slotted nut is rotated, thereby facilitating the adjustment of the compression amount of the disc spring 2-4.

[0032] Furthermore, the guide device 4 includes: a mounting seat 4-1 and a roller 4-2; the mounting seat 4-1 is fixed to the outer side of the side plate 1-2; the roller 4-2 is horizontally mounted on the mounting seat 4-1, and the roller shaft 4-3 passes through the roller 4-2 and the mounting seat 4-1 from top to bottom, and the fixing nut 4-4 is installed to fix the roller 4-2 and the mounting seat 4-1, and the roller 4-2 is in rolling contact with the longitudinal beam 5 below the track beam bottom plate 3. When the vehicle collides with the impact head 7, the roller 4-2 slides along the longitudinal beam 5, thereby playing a guiding role to avoid the entire vehicle stop device from shaking, causing the vehicle stop to be stuck, thereby controlling the buffering resistance and avoiding damage to the vehicle and passengers; the roller shaft 4-3 is a step bolt; a flat washer 4-5 and a spring washer 4-6 are respectively provided between the mounting seat 4-1 and the fixing nut 4-4.

[0033] The embodiment of the present invention uses four sets of rollers 4-2 to ensure that the car stop slides along the track beam, preventing the car stop from deviating from the track center or deflecting during the sliding process, causing the sliding car stop to get stuck, thereby improving the reliability of the car stop.

[0034] Furthermore, the guide device 4 also includes an adjustment pad 4-7, which is fixed to the outer wall of the side plate 1-2, and the mounting seat 4-1 is fixed to the adjustment pad 4-7. By adjusting the thickness of the adjustment pad 4-7, the gap between the roller 4-2 and the longitudinal rib of the track beam is adjusted so that the roller 4-2 can contact the longitudinal rib of the track beam, ensuring reliable guidance of the car stop.

[0035] Furthermore, the vehicle stop device also includes a safety rope 8, one end of the safety rope 8 is fixed on the impact head 7, and the other end is fixed on the vehicle stop seat 1; the impact head 7 and the vehicle stop seat 1 are connected by the safety rope 8 to prevent the impact head 7 from falling during the collision and causing a safety hazard.

[0036] Furthermore, a warning sign 9 is fixed to the bottom of the vehicle stop seat 1 to remind the driver to avoid collision between the vehicle and the vehicle stop device as much as possible.

[0037] The working principle of the vehicle blocking device of the present invention is as follows:

[0038] When the vehicle hits the impact head 7, the hydraulic buffer 6 first plays a certain buffering role, and then drives the vehicle stopper 1 to move forward. The roller 4-2 on the vehicle stopper 1 provides a guiding role to ensure that the vehicle stopper 1 slides along the track beam; at the same time, sliding friction is generated between the friction block 2-2 and the track beam bottom plate 3, applying resistance to the vehicle, thereby realizing sliding buffering of the vehicle, which is safe, reliable, economical and applicable.

[0039] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
