Description

Technical Field

[0001] This utility model relates to the field of vehicle stoppers, and in particular to a wind-powered vehicle stopper. Background Technology

[0002] A vehicle stop is a safety device used to control the movement of vehicles. Its core function is to prevent vehicles from passing without permission, entering dangerous areas, or causing accidents such as runaway or collisions by physically blocking, slowing down, or limiting their movement. It has a wide range of applications, commonly used in road traffic safety, railway and mining rail transport, access control in closed management areas such as schools and factories, and in high-risk areas of the military and security sectors to prevent intrusion. Vehicle stops are typically designed based on the needs of the application scenario and are divided into fixed, mobile, and fully automatic types. Some high-performance models also integrate intelligent control systems, which can automatically start and stop via remote control, card swiping, or sensor signals, ensuring both safety and traffic efficiency.

[0003] In the prior art, Chinese utility model with announcement number CN204399203U discloses a vehicle stopper that stops vehicles by rapidly extending and retracting a cylinder. However, in actual use, it has been found that due to the presence of mining cars, the vehicle stopper occasionally shifts to the side when used to stop vehicles, resulting in an unsatisfactory stopping effect. Utility Model Content

[0004] The purpose of this invention is to provide a wind-driven vehicle stopper in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A pneumatic vehicle stopper includes a support mechanism for protection, a braking and tilting stopping mechanism, and a power mechanism for providing the tilting power to the tilting stopping mechanism. Two tilting stopping mechanisms are symmetrically mounted on the support mechanism. Each tilting stopping mechanism has a buffer mechanism for providing cushioning at its rear side. The power mechanism is installed inside the support mechanism and is correspondingly located below the tilting stopping mechanism. The power mechanism includes a controller, with cylinders on both sides of the controller. The piston rod end of the cylinder is connected to the tilting frame of the tilting parking mechanism via a tilting connecting rod. The tilting parking mechanism also includes a locking block and a rotating shaft. The tilting frame has an inverted L-shaped structure, and the top of the bent end of the tilting frame is connected to the locking block via the rotating shaft. The locking block is an arc-shaped block, and the tilting frame has a groove formed on it to restrict the tilting of the locking block. The inner side of the locking block is connected to the tilting frame via a power assembly.

[0006] Preferably, the power assembly includes a first swing arm and a second swing arm, which are connected by a pin. The other end of the first swing arm is rotatably connected to the locking block by a pin, and the other end of the second swing arm is rotatably connected to the tilting frame by a pin. The connection between the first swing arm and the second swing arm extends out of the tilting frame to the side of the rail corresponding to the rail.

[0007] Preferably, the locking block has a flip angle range of 0°-90°.

[0008] Preferably, the end face of the locking block is formed with friction texture.

[0009] Preferably, the piston cylinder of the cylinder is covered with a protective sleeve made of rubber.

[0010] Preferably, the support mechanism includes a housing and a cover plate, the housing is a hollow housing, and the cover plate is snapped onto the top of the housing.

[0011] Preferably, the buffer mechanism includes an inner guard, a pad, and a buffer component. The inner guard is bolted to the upper end of the housing. A pad is installed on the inner end face of the inner guard. The flipping frame is rotatably connected to the inner guard via a pin. The flipping linkage is integrally formed with the flipping frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The power mechanism controls the tilting parking mechanism to tilt rapidly, thereby providing a vehicle-stopping structure. At the same time, the power component inside the locking block uses the squeezing force of the rail to improve the locking effect of the tilting frame and locking block on the rail, thus improving the vehicle-stopping effect. Combined with the buffer mechanism at the rear end, the overall effect of the device is improved. 2. The quick-release structure facilitates installation and relocation. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-7 As shown, a wind-driven vehicle stopper includes a support mechanism 1 for protection, a braking and tilting parking mechanism 4, and a power mechanism 2 for providing the tilting power to the tilting parking mechanism 4. Two tilting parking mechanisms 4 are symmetrically mounted on the support mechanism 1. Each tilting parking mechanism 4 is provided with a buffer mechanism 3 for providing buffering at its rear side. The power mechanism 2 is installed inside the support mechanism 1 and is correspondingly located below the tilting parking mechanism 4. The power mechanism 2 includes a controller 21, and cylinders 22 are provided on both sides of the controller 21. The piston rod end of the cylinder 22 is connected to the tilting frame 41 of the tilting parking mechanism 4 through the tilting connecting rod 24. The tilting parking mechanism 4 also includes a locking block 42 and a rotating shaft 43. The tilting frame 41 has an inverted L-shaped structure, and the top of the bent end of the tilting frame 41 is connected to the locking block 42 through the rotating shaft 43. The locking block 42 is an arc-shaped block, and a groove is formed on the tilting frame 41 to restrict the tilting of the locking block 42. The inner side of the locking block 42 is connected to the tilting frame 41 through the power component.

[0019] Preferably, the power assembly includes a first swing arm 44 and a second swing arm 45, which are connected by a pin. The other end of the first swing arm 44 is rotatably connected to a locking block 42 by a pin, and the other end of the second swing arm 45 is rotatably connected to a tilting frame 41 by a pin. The connection between the first swing arm 44 and the second swing arm 45 extends out of the tilting frame 41 to the side of the rail corresponding to one side.

[0020] In this embodiment, the locking block 42 has a rotation angle range of 0°-90° to ensure a proper fit with the side of the rail.

[0021] In this embodiment, the end face of the locking block 42 is formed with friction texture to improve the locking effect during locking.

[0022] In this embodiment, the piston cylinder of cylinder 22 is covered with a protective sleeve 23, which is made of rubber, to protect the piston cylinder.

[0023] In this embodiment, the support mechanism 1 includes a housing 11 and a cover plate 12. The housing 11 is a hollow housing, and the cover plate 12 is snapped onto the top of the housing 11.

[0024] In this embodiment, the buffer mechanism 3 includes an inner guard 31, a pad 32, and a buffer 33. The inner guard 31 is bolted to the upper end of the housing 11. The pad 32 is installed on the inner end face of the inner guard 31. The flipping frame 41 is rotatably connected to the inner guard 31 by a pin. The flipping connecting rod 24 is integrally formed with the flipping frame 41.

[0025] Working principle: When the device is needed, cylinder 22 is activated, causing the piston rod of cylinder 22 to extend. Through the connected flipping linkage 24, the flipping frame 41 is flipped. After the flipping frame 41 flips, it locks the rail position. At this time, the connection between the first swing arm 44 and the second swing arm 45 is in contact with the rail and is compressed. The compression force pushes the locking block 42 of the first swing arm 44 and the second swing arm 45 to flip. After the locking block 42 flips, its side locks the side of the rail, thus ensuring the fixing effect. When the mine car touches the flipping frame 41, it is first buffered by the rear buffer 33. At the same time, the locking of the flipping frame 41 and the locking block 42 also ensures the fixing and braking effect.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
