Description

Technical Field

[0001] This utility model relates to the technical field of trackless rubber-tired vehicles, and in particular to a vehicle stopper for trackless rubber-tired vehicles used in coal mines. Background Technology

[0002] Trackless rubber-tired vehicles are a modern auxiliary transportation tool used in mines, primarily for transporting materials, equipment, and personnel underground in coal mines. Powered by an explosion-proof diesel engine, they employ mechanical transmission and a wet braking system, enabling rear-wheel drive. These vehicles do not rely on tracks, possessing high mobility and adaptability, and can operate in complex and ever-changing mine environments.

[0003] Currently, trackless rubber-tired vehicles are parked in parking lots using vehicle braking devices. During maintenance, due to different vehicle malfunctions, the parking brake device may not function properly. Therefore, a vehicle stopper is needed to limit the trackless rubber-tired vehicle to a designated position and prevent runaway or slippage accidents.

[0004] Currently, the trackless rubber-tired vehicle stoppers used underground are mostly triangular stoppers made of rubber. Although they have a good stopping effect, the rubber material is prone to wear after frequent use, which leads to a decrease in stopping performance and fails to meet the high requirements of safe production in coal mines. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-performance, wear-resistant, and multifunctional track stop for trackless rubber-tired vehicles in coal mines.

[0006] This utility model discloses a vehicle stopper for trackless rubber-tired vehicles in coal mines, comprising:

[0007] The main frame is used to support the components;

[0008] Brake wedges are mounted on the main frame. The surface of the brake wedges is provided with anti-slip textures, which are intersecting diamond patterns.

[0009] The buffer mechanism is connected between the main frame and the brake wedge. The buffer mechanism includes a spring and a buffer pad. One end of the spring is fixed to the main frame and the other end is connected to the brake wedge. The buffer pad is located on the side of the brake wedge that contacts the main frame and is used to buffer the impact force during a vehicle collision.

[0010] The fixing mechanism, located at the bottom of the main frame, is used to fix the vehicle stopper to the ground. The fixing mechanism includes a fixing component and a fixing plate. The fixing plate is fixed to the ground by the fixing component, and the main frame and the fixing plate are detachably connected.

[0011] Furthermore, the main frame includes two parallel main beams and a crossbeam connecting the two main beams, a brake wedge is disposed between the two main beams, and a buffer mechanism is disposed between the two main beams and the brake wedge.

[0012] Furthermore, protective plates are provided on both sides of the main frame, and the protective plates are made of steel plates.

[0013] Furthermore, the main frame is made of high-strength alloy steel, and its surface is coated with an anti-rust coating.

[0014] Furthermore, the brake wedge is shaped like a right trapezoid, with its hypotenuse in contact with the wheel.

[0015] Furthermore, the buffer mechanism also includes a damper, which is connected in parallel with the spring to slow down the rebound speed of the brake wedge.

[0016] Furthermore, the fixing mechanism also includes an adjusting component, which is disposed between the fixing plate and the main frame and is used to adjust the height of the main frame.

[0017] Furthermore, it also includes a warning mechanism, which is installed on the main frame and includes warning lights and sirens.

[0018] Furthermore, the warning mechanism also includes a pressure sensor, which is mounted on the brake wedge.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The main frame is made of high-strength alloy steel, which has higher strength and stability than traditional rubber wheel stops, and can withstand greater impact. It effectively avoids the decline in wheel-stopping performance caused by structural damage after frequent use. At the same time, the anti-rust coating on the surface further enhances its corrosion resistance in the humid environment of the mine and extends its service life.

[0021] 2. The cross-shaped diamond anti-slip texture on the surface of the brake wedge increases the friction with the wheel, which can reliably prevent the vehicle from sliding even in the event of emergency braking or in adverse conditions such as water accumulation or debris on the track, thus improving the stability and reliability of the braking effect. The right-angled trapezoidal design of the brake wedge allows its hypotenuse to better fit the wheel profile when it contacts the wheel, dispersing the impact force of the vehicle and further improving the braking effect.

[0022] 3. The springs and buffer pads in the buffer mechanism work together to effectively absorb and disperse the impact force when a vehicle collides with the brake, reducing damage to the brake and the vehicle; the damper reduces the rebound speed of the brake wedge, further enhancing the buffering effect and improving safety during the braking process.

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0028] like Figures 1 to 2 As shown, this utility model discloses a trackless rubber-tired vehicle brake for coal mines, comprising:

[0029] Main frame 1, used to support components;

[0030] Brake wedge 2 is set on the main frame 1. The surface of brake wedge 2 is provided with anti-slip texture, which is a cross diamond pattern.

[0031] The buffer mechanism 3 is connected between the main frame 1 and the brake wedge 2. The buffer mechanism 3 includes a spring 31 and a buffer pad 32. One end of the spring 31 is fixed on the main frame 1 and the other end is connected to the brake wedge 2. The buffer pad 32 is set on the side of the brake wedge 2 that contacts the main frame 1 and is used to buffer the impact force during vehicle collision.

[0032] The fixing mechanism 4 is set at the bottom of the main frame 1 and is used to fix the vehicle stopper on the ground. The fixing mechanism 4 includes a fixing member 41 and a fixing plate 42. The fixing plate 42 is fixed to the ground by the fixing member 41. The main frame 1 and the fixing plate 42 are detachably connected.

[0033] When the trackless rubber-wheeled vehicle needs to be parked or inspected and stops at the wheel stop position, the vehicle's wheels contact the brake wedge 2 of the wheel stop. Because the surface of the brake wedge 2 has a cross-shaped diamond anti-slip pattern, it increases the friction between the vehicle and the wheels, providing initial wheel stop. At the moment the vehicle collides with the wheel stop, the buffer mechanism 3 activates. The buffer pad 32 first absorbs a portion of the impact force, and then the spring 31 is compressed. The elastic deformation of the spring 31 further absorbs and buffers the impact force generated by the vehicle collision, preventing damage to the wheel stop due to excessive impact force. The fixing mechanism 4 securely fixes the wheel stop to the ground, ensuring that the wheel stop will not shift during the entire wheel stop process, thus reliably limiting the vehicle to the designated position and preventing runaway or slippery accidents. The main frame 1 is detachably connected to the ground via the fixing parts 41 and the fixing plate 42. Installation is relatively simple, and the installation position can be flexibly adjusted according to the actual ground conditions. When the wheel stop needs inspection or replacement of parts, it can also be easily and quickly disassembled and reinstalled.

[0034] The main frame 1 includes two parallel main beams 11 and a crossbeam 12 connecting the two main beams 11. The brake wedge 2 is disposed between the two main beams 11, and the buffer mechanism 3 is disposed between the two main beams 11 and the brake wedge 2. The main beams 11 bear the main supporting role and can withstand the vehicle compression force transmitted from the brake wedge 2 and the force of the buffer mechanism 3. The crossbeam 12 connects the two main beams 11 into a stable overall frame structure, which enhances the stability and integrity of the main frame 1 and ensures that the entire vehicle stopper will not deform or fall apart in the event of a vehicle collision, thereby continuously and effectively performing the vehicle stopping function.

[0035] The main frame 1 is preferably provided with protective plates 13 on both sides. The protective plates 13 are made of steel plates. The steel plate material has high strength and hardness, and can block the impact of falling coal blocks, gangue and other objects that may exist in the mine on the internal structure of the main frame 1 by its own physical properties. This prevents the key components inside the main frame 1 from being damaged by concentrated impact force. At the same time, the protective plates 13 act as a barrier to prevent small particles of coal dust, debris and other foreign objects that may exist in the mine environment from entering the main frame 1. This prevents them from affecting the normal sliding of the brake wedge 2 and the buffering effect of the buffer mechanism 3, maintaining the normal working state of each component of the vehicle stopper and ensuring the normal operation of the vehicle stopper.

[0036] The main frame 1 is preferably made of high-strength alloy steel with an anti-rust coating. Alloy steel is made by adding various alloying elements, such as manganese, chromium, and nickel, to ordinary steel, thereby altering its internal structure and improving its strength, toughness, and other mechanical properties. When the trackless rubber-tired vehicle brake is in operation, the enormous impact force generated by the vehicle collision is transmitted to the main frame 1. The high-strength alloy steel, with its excellent mechanical properties, can withstand these powerful external forces, ensuring that the main frame 1 will not deform, break, or suffer other damage, and continuously providing stable support for components such as the brake wedge 2, the buffer mechanism 3, and the protective plate 13. A reliable support is provided to ensure the integrity and normal operation of the overall structure of the vehicle stopper. The anti-rust coating is composed of materials with anti-oxidation and anti-corrosion properties, such as epoxy resin and polyurethane. These materials form a dense protective film on the surface of the main frame 1, isolating the main frame 1 from oxygen, moisture, corrosive gases and other impurities in the external environment. In the humid environment of underground coal mines containing certain corrosive substances, the isolation effect of the anti-rust coating reduces the probability of the alloy steel reacting chemically with these corrosive media, thereby effectively preventing the main frame 1 from rusting and corroding, and maintaining its structural strength and performance stability.

[0037] The preferred shape of the brake wedge 2 is a right-angled trapezoid, with its hypotenuse in contact with the wheel. When the trackless rubber-tired vehicle approaches the brake stop, the wheel contacts the hypotenuse of the right-angled trapezoidal brake wedge 2. The pressure generated by the vehicle's continuous forward movement acts on the hypotenuse. According to the principle of force decomposition, this pressure is decomposed into two components: one perpendicular to the ground and one parallel to the ground. The perpendicular component increases the friction between the brake wedge 2 and the ground, making it stable and preventing slippage. The parallel component pushes the brake wedge 2 to move in the opposite direction of the wheel's rolling, increasing the blocking force on the wheel. At the same time, the anti-slip texture on the surface of the brake wedge 2 further increases the friction with the wheel, effectively preventing the wheel from rolling and achieving the purpose of vehicle braking.

[0038] The preferred buffer mechanism 3 also includes a damper 33, which is connected in parallel with the spring 31 to slow down the rebound speed of the brake wedge 2. The internal structure of the damper 33 is mostly based on the viscous properties of liquids or gases. When the brake wedge 2 drives the damper 33 to move, the liquid or gas flows inside the damper 33 and generates viscous resistance. The direction of this resistance is opposite to the rebound direction of the brake wedge 2, thereby slowing down the rebound speed of the brake wedge 2. The smooth rebound process reduces the stress on the components, extends the service life of the buffer mechanism 3 and the brake wedge 2, reduces the frequency of maintenance and replacement of components, and reduces the cost of use.

[0039] The preferred fixing mechanism 4 also includes an adjusting component 43, which is disposed between the fixing plate 42 and the main frame 1 and is used to adjust the height of the main frame 1. The adjusting component 43 is usually a threaded component, such as a combination of a screw and a nut. When it is necessary to adjust the height of the main frame 1, the screw will move up and down relative to the fixing plate 42 by rotating the nut in the adjusting component 43. Since the main frame 1 is connected to the screw, the movement of the screw drives the main frame 1 to rise and fall synchronously, thereby achieving precise adjustment of the height of the main frame 1. By utilizing the principle of threaded transmission, the height change can be controlled stably and accurately. By adjusting the height of the main frame 1, the brake wedge can be adapted to different ground conditions. For example, in areas with a certain slope, the height of the main frame 1 can be appropriately adjusted to ensure that the brake wedge 2 can accurately contact the wheel and play a braking role, avoiding poor braking effect due to improper height, and improving the applicability of the brake wedge in complex mining environments.

[0040] To further enhance safety, a warning mechanism 5 is also provided. The warning mechanism 5 is installed on the main frame 1 and includes a warning light 51 and an alarm 52. The warning light 51 is a red flashing light, and the alarm 52 can emit an alarm sound. By illuminating the warning light 51 and sounding the alarm 52, the driver and surrounding personnel are strongly alerted visually and audibly in emergency situations or when the driver is not paying attention, reducing the possibility of accidents and ensuring the safety of personnel and equipment.

[0041] The preferred warning mechanism 5 also includes a pressure sensor 53, which is mounted on the brake wedge 2. The pressure sensor 53 operates based on principles such as piezoelectric or piezoresistive effects. When the vehicle compresses the brake wedge 2, the brake wedge 2 deforms under pressure. The pressure sensor 53 senses this pressure change and converts the pressure signal into an electrical signal, which is transmitted to the control system. The control system judges the pressure based on a preset pressure threshold. If the pressure exceeds the threshold, the control system triggers the warning light 51 to illuminate and the alarm 52 to sound an alarm. Compared to simply relying on a vehicle detection device to trigger a warning, the pressure sensor 53's pressure-sensing method is more direct. Accurate connection allows drivers and surrounding personnel to detect dangers earlier, take preventative measures, avoid serious accidents, and ensure the safety of personnel and equipment. Simultaneously, the pressure sensor 53 not only functions during normal vehicle braking but also provides early warning of malfunctions in the brake wedge itself. If the pressure sensor 53 detects abnormal pressure on the brake wedge 2 without vehicle pressure, it may indicate displacement, deformation, or abnormal force caused by other component malfunctions. In this case, the warning light 51 and alarm 52 issue a warning signal, reminding maintenance personnel to promptly inspect and repair the brake wedge to prevent mine transportation safety from being affected by brake wedge malfunctions.

[0042] This utility model discloses a trackless rubber-tired vehicle stopper for coal mines. During operation, when the trackless rubber-tired vehicle approaches the stopper, the vehicle's wheels contact the brake wedge 2. The brake wedge 2 has a cross-shaped anti-slip pattern on its surface, increasing friction with the wheels and providing initial stopping power. At the moment of impact, the buffer mechanism 3 activates. The buffer pad 32 initially absorbs a portion of the impact force, followed by the compression of the spring 31. The elastic deformation of the spring 31 further absorbs and buffers the impact force generated by the vehicle collision. At this time, the internal liquid or gas flow of the damper 33 generates viscous resistance, slowing the rebound speed of the brake wedge 2 and preventing damage to the stopper due to excessive impact force. When the vehicle squeezes the brake wedge 2, the pressure sensor 53 detects the pressure change and transmits the signal to the control system. If the pressure exceeds a preset threshold, the control system triggers the warning light 51 to illuminate and the alarm to sound, visually and audibly alerting the driver and surrounding personnel.

[0043] The present invention relates to a trackless rubber-tired vehicle stopper for coal mines. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
