Description

Technical Field

[0001] This invention belongs to the field of safety protection technology for motor vehicles and other vehicles in a state of loss of control, and more specifically, it relates to a device and method for preventing motor vehicles from losing control. Background Technology

[0002] When a mine car moves down a steep slope, it is usually pulled by a cable car to prevent it from falling. However, if the cable car's pull line breaks, it can easily cause the mine car to go out of control. If there are workers in front of it, it can easily cause safety accidents such as workers being hit and injured.

[0003] In the existing technology, although some monitoring agencies can detect out-of-control motor vehicles or mining trucks in a timely manner, their blocking effect is poor, which can easily allow the mining truck to continue moving forward and cause accidents. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a device and method for stopping motor vehicles when they are out of control. It is mainly used for uncontrolled situations during mining operations, and is particularly suitable for environments such as hillsides, so as to stop the vehicles in time and prevent accidental injury to workers.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Braking devices for vehicles that are out of control include,

[0007] A first blocking assembly, the first blocking assembly includes a blocking surface that is suspended in the air, and the blocking surface is connected to a force-bearing mechanism through a pulley assembly;

[0008] The force-bearing mechanism includes a piston assembly and a liquid tank connected to the piston assembly. The piston assembly includes a piston located inside the main body and a connecting rod connected to the piston. The end of the connecting rod is connected to a pulley assembly. Liquid is pre-stored between the connecting rod and the inner wall of the main body. The outer side of the connecting rod is connected to the liquid tank through a connecting pipe.

[0009] The liquid tank is provided with a cover plate on the top for opening the liquid tank. The cover plate has a vent hole in the center and is connected to the top of the cover plate circumferentially by a number of elastic components.

[0010] As a further improvement of the present invention, the barrier surface is an umbrella-shaped structure, the umbrella-shaped structure forms a flexible barrier surface, and a plurality of skeleton structures are provided on the inner wall of the umbrella-shaped structure.

[0011] As a further improvement of the invention, it also includes a mounting frame that spans a lane or track, wherein the mounting frame suspends the umbrella-shaped structure in the air via a suspension member.

[0012] As a further improvement of the present invention, a plurality of traction components are provided on the barrier surface, and the traction components are assembled and sleeved on the assembly shell of the pulley assembly. Inside the assembly shell, the ropes located on the movable pulley are respectively connected to the connecting rod and the stone block fixed to the side of the lane or track.

[0013] As a further improvement of the present invention, there are several piston assemblies, which are assembled by a frame assembly fixed to the outside of the lane or track to form a piston group.

[0014] As a further improvement of the present invention, a filter assembly is provided at the end of the main body away from the connecting rod.

[0015] As a further improvement of the present invention, it also includes a second blocking assembly, the second blocking assembly including blocking surfaces located on both sides of the lane or track, and a drive mechanism for moving the blocking surfaces closer to or further away.

[0016] The present invention also discloses a method for using a braking device for a motor vehicle that is out of control as described above, comprising the following steps:

[0017] Activation of the first barrier component: The suspended barrier surface is lowered to form a barrier surface located on the track or lane to block the movement of motor vehicles.

[0018] Force on the piston assembly: When the out-of-control vehicle comes into contact with the barrier surface, it causes the barrier surface to move, which in turn causes the connecting rod in the force-bearing mechanism to perform an intake motion, thereby realizing the movement of the piston assembly;

[0019] The first blocking component blocks the flow of air: the piston assembly draws in air, and the pre-stored liquid inside the piston is squeezed into the liquid tank, causing the liquid level in the liquid tank to rise. When the water level rises, water pressure is generated, which slows down the flow of the liquid and slows down the movement of the connecting rod, thus achieving the blocking effect of the first blocking component.

[0020] As a further improvement of the present invention, the force on the piston assembly specifically involves the blocking surface driving several piston assemblies within the frame assembly to perform synchronous suction motion, thereby achieving synchronous movement of several piston assemblies.

[0021] As a further improvement of the present invention, it also includes the blocking of a second blocking component, specifically: the second blocking component uses a driving mechanism to drive the blocking surface to move toward the lane or track, forming a blocking surface, locking the motor vehicle, and thus forcing it to stop.

[0022] The beneficial effects of this invention are as follows:

[0023] In this invention, a piston assembly is cleverly utilized so that when the piston is pulled out, water enters the liquid tank, squeezing the water in the tank and causing it to move upwards. The pressure of the water slows down the speed at which the liquid enters, thereby slowing down the movement of the piston and achieving the effect of obstruction.

[0024] In this invention, a cover plate and a vent are added to allow air to flow out of the water tank. When the vehicle speed is high, the impact on the blocking surface is large, causing the water to be forced to rise suddenly. This impacts the elastic components, forcing the cover plate to open and the liquid to rush out, thus forcing the vehicle with high speed or inertia to stop.

[0025] In this invention, fluorescent powder or other substances can be added to the liquid tank. Once the water or other liquid in the liquid tank is sprayed out, it will spray out a fluorescent liquid. In dark or poor lighting conditions, the mine car can be observed to be blocked in time, making it easy to identify. Attached Figure Description

[0037] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" 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. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] See attached document Figure 1-9 As shown, the vehicle control device of the present invention has two blocking components. Generally, the first blocking component 100 is sufficient. (Refer to the attached diagram.) Figure 1-5 As shown, the first blocking component 100 in this embodiment includes a suspended blocking surface 110, and the blocking surface 110 is connected to a force-bearing mechanism 200 through a pulley assembly 120.

[0041] Referring to the accompanying drawings, specifically, the force-bearing mechanism 200 includes a piston assembly 210 and a liquid tank 220 connected to the piston assembly 210. The piston assembly 210 includes a piston 212 located inside the main body 211 and a connecting rod 213 connected to the piston 212. The end of the connecting rod 213 is connected to the pulley assembly 120. Liquid is pre-stored between the connecting rod 213 and the inner wall of the main body 211. The outer side of the connecting rod 213 is connected to the liquid tank 220 through a connecting pipe 240.

[0042] The liquid tank 220 is provided with a cover plate 221 for opening the liquid tank 220. A vent hole 222 is provided in the center of the cover plate 221, and the cover plate 221 is connected to the top of the cover plate 221 circumferentially by a number of elastic components 223.

[0043] In this invention, the working principle and process of the first blocking component are as follows:

[0044] When a mine car or other vehicle goes out of control, firstly, the sensing or control components on or near the track detect the loss of control and need to stop the car. At this time, the blocking surface 110 on the first blocking component 100 is activated, causing the suspended blocking surface to be lowered onto the track. The moving mine car comes into contact with the blocking surface, causing it to continue moving. The pulley assembly on the blocking surface acts, driving the piston assembly in the stationary force-bearing mechanism to move in the same direction as the mine car. At this time, the piston assembly uses a principle similar to an injection needle to draw gas into the main body, which then reacts with the liquid present between the connecting rod and the main body. The liquid at this point can be water or other liquids, which are squeezed into the liquid tank. The liquid tank already contains liquid, and the existing liquid is squeezed upwards. Due to the water pressure, the upward movement of the water slows down, and the piston assembly slows down, thus achieving a blocking effect. However, when the mine car is moving too fast or experiences significant inertia, a sudden and large force acts on the blocking surface, causing the water pressure to rise rapidly and rush towards the cover of the liquid tank. At this time, the gas inside the liquid tank is discharged through the vent or directly acts on the cover, using the elastic component to force the cover open, thus achieving a blocking effect.

[0045] To achieve a better blocking effect, the blocking surface 110 has an umbrella-shaped structure, forming a flexible blocking surface. Several skeletal structures are provided on the inner wall of the umbrella-shaped structure. In this embodiment, the skeletal structures within the blocking surface, such as reinforcing ribs parallel to the width direction of the umbrella-shaped structure, provide two advantages: firstly, the flexible blocking surface offers some protection to the mine car; secondly, the skeletal structures increase the internal strength, preventing the mine car from directly passing through the flexible surface of the umbrella-shaped structure, thus achieving the blocking effect.

[0046] In this embodiment, as shown in the accompanying drawings, a mounting frame 250 spanning the lane or track is also included. The mounting frame 250 suspends the umbrella-shaped structure in mid-air via a suspension member 251. The mounting frame allows for a larger space between the umbrella-shaped structure and the lane or track when not in use, facilitating the normal passage of mine cars and offering advantages such as minimal space occupation. (Refer to the accompanying drawings.) Figure 6 As shown, in order to control the lower part of the blocking surface 110 on the mounting frame in a timely manner, the mounting frame 250 clamps the entire suspension component 251 by means of a push rod. Specifically, a push rod is provided at the top of the mounting frame 250, and the mounting frame extends downward to form an extension surface. The extension surface and the push rod are connected by a clamping plate to form a clamping assembly. The clamping plate moves toward the extension surface of the mounting frame 250 to achieve clamping, and moves backward to lower the suspension component. In this embodiment, the push rod, etc., can move along a track via a slide rail or the like inside the mounting frame 250. For example, a slide rail in the prior art can be used, and then a slider is provided on the push rod toward the slide rail side to make it move along the inner wall of the mounting frame.

[0047] To ensure the normal movement and use of the barrier surface, a plurality of traction components 130 are provided on the barrier surface 110. The traction components 130 are assembled and fitted onto the assembly shell 121 of the pulley assembly 120. Inside the assembly shell 121, ropes 123 located on the movable pulley 122 are respectively connected to the connecting rod 213 and the stone block 140 fixed to the side of the lane or track. In this embodiment, using ropes, a plurality of traction components 130 are connected to the assembly shell, and the barrier surface drives the entire assembly shell to move. The movable pulley and rope inside the assembly shell form a connecting assembly, one side of which is fixed to the stone block, etc., and the other side pulls the connecting rod to move. The rope moves within the movable pulley as the connecting rod moves.

[0048] See attached document Figure 6-7 As shown, in this embodiment, there are several piston assemblies 210. These piston assemblies 210 are assembled together by a frame assembly 150 fixed to the outside of the track or carriageway to form a piston group. In this embodiment, the several piston assemblies are arranged side by side, so that the connecting rod synchronously drives several cylinders to move. At this time, the several cylinders are connected by a connecting rod on the side of the frame assembly, and then the connecting rod drives the connecting rod to achieve synchronous control of multiple cylinders. Compared with a single cylinder, this structure distributes the pulling force generated by the mine car to each cylinder when under force, thereby reducing the amount of water flowing out of each piston assembly.

[0049] When the cylinder assembly is in operation, to prevent impurities in the air from entering the cylinder and contaminating the liquid tank, a filter assembly 214 is provided at the end of the main body 211 away from the connecting rod 213. In this embodiment, the filter assembly is specifically made of filter paper or similar materials.

[0050] If the first blocking assembly fails to stop the mine car but allows it to slow down, a second blocking assembly 300 is also included. The second blocking assembly 300 includes blocking surfaces 310 located on both sides of the lane or track, and a drive mechanism 320 that moves the blocking surfaces 310 closer to or further away from them. In actual use, by controlling the drive mechanism 320, the blocking surfaces are moved onto the lane or track, thus stopping the car. If two symmetrical blocking assemblies are used, this symmetrical arrangement ensures that the entire lane or track is blocked, causing the mine car or other motor vehicle to lock up and stop.

[0051] In this invention, by utilizing the appendix Figure 1-8 The blocking device and the blocking method implemented in the middle include the following steps:

[0052] The first blocking component 100 is activated: the suspended blocking surface 110 is lowered to form a blocking surface located on the track or lane to block the movement of motor vehicles.

[0053] Force on piston assembly 210: When the out-of-control vehicle comes into contact with the blocking surface 110, it causes the blocking surface 110 to move, which in turn causes the connecting rod 213 in the force-bearing mechanism 200 to perform an air intake movement, thereby realizing the movement of piston assembly 210.

[0054] The first blocking component 100 blocks the flow of air: the piston assembly 210 draws in air, and the pre-stored liquid inside the piston is squeezed into the liquid tank 220, causing the liquid level in the liquid tank 220 to rise. When the water level rises, water pressure is generated, which slows down the flow of the liquid and slows down the movement of the connecting rod 213, thus achieving the blocking effect of the first blocking component 100.

[0055] The core of the control method of the present invention lies in the force on the entire piston assembly. Specifically, the force on the piston assembly is such that the blocking surface drives several piston assemblies in the frame assembly to perform synchronous suction movement, thereby realizing the synchronous movement of several piston assemblies.

[0056] In this invention, when the first blocking component 100 is unable to stop the entire out-of-control motor vehicle and can only slow down, the second blocking component 300 is also included for blocking. Specifically, the second blocking component 300 uses the driving mechanism 320 to drive the blocking surface 310 to move toward the lane or track, forming the blocking surface 310, locking the motor vehicle, and thus forcing it to stop.

[0057] In this invention, an air intake hole is provided at the tail end of the piston assembly body, thereby moving the piston to allow air to enter the body, which in turn forces the liquid (i.e., pre-stored water) at the other end of the piston into the liquid tank. Moreover, the process of forcing water into the liquid tank is damped, and it has the characteristic that the resistance is dynamic; the faster the mine car travels, the greater the resistance.

[0058] In this invention, a liquid tank 220 is provided on the side of the cylinder assembly. When the large connecting rod 213 moves, the liquid in multiple bodies is discharged and enters the liquid tank. The liquid tank is relatively high and has a relatively large force, which is used to stop the locomotive.

[0059] In this embodiment, a vent is provided on the top of the liquid tank. When the water pressure is high, there is too much gas. Therefore, a vent plate can also be provided on the top of the liquid tank. The vent plate is connected to the top of the liquid tank by a spring. When the water pressure is high, there is too much air. The pressure of the air or water pushes up the spring, causing the vent plate with the vent to be lifted, thus achieving the blocking effect.

[0060] Furthermore, in this invention, a grid plate can be installed at the bottom of the liquid tank. When subjected to force, the grid plate inside the liquid tank disperses the water level, causing the water to flow upward. Since there is already water in the tank, the water inside the tank is pushed up, creating a rupture that directly blows the cover plate away.

[0061] In this embodiment, the body of the cylinder assembly is a pipeline structure, the length of which is 8-6m and the diameter is not less than 120mm.

[0062] The blocking method in this invention, compared to other blocking methods, creatively utilizes the working principle of a cylinder, integrating the rising water pressure within the liquid tank and the overall linkage control. Throughout the process, the majority of the energy consumed is the liquid in the tank, and the device is discarded after use, making the entire first blocking component a disposable device. Compared to traditional methods of applying external force or setting up other interceptions, this invention uses less external force, resulting in lower costs. It only requires a blocking surface, in conjunction with a force-receiving mechanism, to receive the force applied to the blocking surface by the out-of-control vehicle, converting it into the pressure of rising water using a syringe principle. The control method is simple and the control effect is good.

[0063] This invention can also be used for the control of motor vehicles, such as cars on bridges. The first blocking component has two piston components, which are symmetrically arranged on both sides of the track, and are connected to both sides of the same blocking surface. At this time, the out-of-control motor vehicle drives the piston components on both sides to pump air. Relatively speaking, the pressure is relatively large, which can ensure better blocking control.

[0064] In this invention, the entire barrier assembly is easy to obtain and assemble, making it more suitable for mountain roads and ordinary tracks. The liquid tank can contain water or other liquids, and the main body is pre-filled with the same liquid as the liquid tank to reduce pollution.

[0065] In this invention, during assembly, the frame assembly is located on the side of the liquid tank. It can be fixed to the side of the track or carriageway via a fixing plate or similar device. Furthermore, a diagonal brace can be installed on the side of the frame assembly closest to the track or carriageway to prevent direct contact between the mine car and the piston assembly, thus providing further protection for the mine car. In this invention, several connecting rings can be added to both sides of the piston. These connecting rings are connected to connecting rods, and finally to ropes or similar devices to achieve the overall blocking effect.
