Description

Technical Field

[0001] This utility model relates to the field of explosion-proof vehicle technology, and more specifically, to a parking warning device for explosion-proof vehicles. Background Technology

[0002] Explosion-proof trackless rubber-tired vehicles are transport vehicles designed with special explosion-proof technology that can operate safely in environments containing explosive gases (such as methane) or combustible dust. They use rubber tires to achieve trackless travel, and the vehicle body is made of anti-static coating. They are mainly used for transporting personnel, materials, and equipment. They are flexible, maneuverable, and adaptable to complex road conditions, making them a key transport tool in underground mines, hazardous chemical plants, and other scenarios.

[0003] When the existing explosion-proof trackless rubber-tired vehicle is in use, the braking system has sufficient pressure to push the brake pads to brake and park when the vehicle's handbrake valve is in the on state. However, after the vehicle stops, it is inconvenient for the driver to visually confirm whether the vehicle's braking system has braked reliably. The driver needs to repeatedly check the position of the handbrake valve and step on the brake pedal, which is cumbersome. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an explosion-proof vehicle parking warning device, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a parking warning device for explosion-proof vehicles, comprising a mounting cylinder and a flange, wherein one end of the flange is fixedly connected to the mounting cylinder, and a first gasket is fixedly bonded to the other end of the flange; a pressure detector is fixedly installed on one side of the interior of the mounting cylinder, a wire harness is fixedly installed on the pressure detector, and a display screen is fixedly installed at the other end of the wire harness; L-shaped plates are provided on both the front and rear sides of the pressure detector, and one side of each of the two L-shaped plates is fixedly connected to the mounting cylinder; an extrusion assembly is provided between the two L-shaped plates, the extrusion assembly comprising a convex plate, a pressure plate, an external threaded sleeve, and two connecting rods; the pressure plate is fixedly installed at the center position of one side of the convex plate; one end of each of the two connecting rods is fixedly connected to the external threaded sleeve, and the other ends of the two connecting rods respectively penetrate the two L-shaped plates.

[0006] Furthermore, each of the two L-shaped plates has a movably arranged circular plate inside, and one end of each circular plate is fixedly connected to a connecting rod.

[0007] Furthermore, springs are fixedly connected to the other ends of both circular plates, and the other ends of both springs are fixedly connected to the mounting cylinder.

[0008] As can be seen, in the above technical solution, when there is no braking, the pressure in the brake hydraulic line decreases, and the two springs rebound to drive the convex plate to reset.

[0009] Furthermore, the external threaded sleeve is threadedly connected to an internal threaded sleeve, and one end of the internal threaded sleeve is fixedly connected to the convex plate.

[0010] As can be seen, in the above technical solution, rotating the horizontal plate causes the convex plate and the internal threaded sleeve to rotate, and the internal threaded sleeve moves away from the external threaded sleeve, allowing the convex plate to be disassembled and replaced.

[0011] Furthermore, a second gasket is fixedly bonded to the convex plate, and the outer side of the second gasket is in contact with the mounting cylinder.

[0012] As can be seen, in the above technical solution, the second gasket can improve the sealing between the convex plate and the mounting cylinder.

[0013] Furthermore, a horizontal plate is fixedly connected to the center of the other end of the convex plate.

[0014] It can be seen that the above technical solution is designed to facilitate the rotation of the convex plate.

[0015] Furthermore, a transparent plate is fixedly embedded in the mounting cylinder.

[0016] As can be seen from the above technical solution, the position of the convex plate can be observed through the transparent plate.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model uses bolts to install the flange on the brake hydraulic line. When the handbrake valve is activated, the pressure in the brake hydraulic line changes. The pressure plate squeezes the pressure detector, which detects the pressure in the brake hydraulic line and transmits the pressure data to the display screen. The display screen can alert and warn the driver. The operation is simple and convenient, allowing for intuitive confirmation of whether the vehicle's braking system has braked reliably.

[0019] 2. This utility model uses a convex plate to drive the external threaded sleeve and the internal threaded sleeve to move horizontally, thereby driving the two connecting rods and the two circular plates to move horizontally. The two circular plates drive the two springs to compress, rotating the horizontal plate and thus driving the convex plate and the internal threaded sleeve to rotate, so that the internal threaded sleeve moves away from the external threaded sleeve, allowing the convex plate to be disassembled and replaced. The structure is simple and easy to use. Attached Figure Description

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Refer to the instruction manual appendix Figures 1-5This embodiment of an explosion-proof vehicle parking warning device includes a mounting cylinder 1 and a flange 5. One end of the flange 5 is fixedly connected to the mounting cylinder 1, and the other end of the flange 5 is fixedly bonded with a first gasket 6. A pressure detector 8 is fixedly installed on one side of the interior of the mounting cylinder 1. A wire harness 2 is fixedly installed on the pressure detector 8, and a display screen 3 is fixedly installed on the other end of the wire harness 2. L-shaped plates 9 are provided on both the front and rear sides of the pressure detector 8, and one side of each of the two L-shaped plates 9 is fixedly connected to the mounting cylinder 1. An extrusion assembly 4 is provided between the two L-shaped plates 9. The extrusion assembly 4 includes a convex plate 401, a pressure plate 402, an external threaded sleeve 403, and two connecting rods 404. The pressure plate 402 is fixedly installed at the center of one side of the convex plate 401. One end of each of the two connecting rods 404 is fixedly connected to the external threaded sleeve 403, and the other ends of the two connecting rods 404 pass through the two L-shaped plates 9 respectively.

[0029] Furthermore, a circular plate 405 is movably disposed inside each of the two L-shaped plates 9, and one end of each circular plate 405 is fixedly connected to a connecting rod 404. A spring 406 is fixedly connected to the other end of each circular plate 405, and the other end of each spring 406 is fixedly connected to the mounting cylinder 1. An internal threaded sleeve 407 is threadedly connected to the external threaded sleeve 403, and one end of the internal threaded sleeve 407 is fixedly connected to the convex plate 401. A second gasket 408 is fixedly bonded to the convex plate 401, and the outer side of the second gasket 408 is in contact with the mounting cylinder 1. A horizontal plate 10 is fixedly connected to the center of the other end of the convex plate 401.

[0030] Furthermore, a transparent plate 7 is fixedly embedded in the mounting cylinder 1.

[0031] The convex plate 401 drives the external threaded sleeve 403 and the internal threaded sleeve 407 to move horizontally, thereby driving the two connecting rods 404 and the two circular plates 405 to move horizontally. The two L-shaped plates 9 and the two connecting rods 404 cooperate to prevent the convex plate 401 from deflecting during horizontal movement. The circular plates 405 prevent the connecting rods 404 from moving out of the L-shaped plates 9. The two circular plates 405 drive the two springs 406 to compress. When there is no braking, the pressure in the braking hydraulic line decreases, and the two springs 406 rebound to drive the convex plate 401 to reset. Rotating the horizontal plate 10 drives the convex plate 401 and the internal threaded sleeve 407 to rotate, and makes the internal threaded sleeve 407 move away from the external threaded sleeve 403, so that the convex plate 401 can be disassembled and replaced. The structure is simple and easy to use. At the same time, the position of the convex plate 401 can be observed through the transparent plate 7.

[0032] The usage method of this embodiment is as follows:

[0033] In use, flange 5 is bolted onto the brake hydraulic line, connecting mounting cylinder 1 to the brake hydraulic line. The first gasket 6 improves the seal between flange 5 and the brake hydraulic line. Similarly, display screen 3 is installed in the cab of the explosion-proof trackless rubber-tired vehicle. When the handbrake valve is activated, the pressure in the brake hydraulic line changes, causing the convex plate 401 to move horizontally. At the same time, the second gasket 408 improves the seal between the convex plate 401 and mounting cylinder 1, and the convex plate 401 causes the pressure plate 402 to move horizontally. The pressure plate 402 presses the pressure detector 8, which detects the pressure in the brake hydraulic line and transmits the pressure data to display screen 3. Display screen 3 can then alert or warn the driver. The operation is simple and provides a convenient and intuitive way to confirm whether the vehicle's braking system is reliably braking.
