Description

Technical Field

[0001] This utility model relates to the field of mining equipment, specifically to a hydraulic automatic vehicle blocking device. Background Technology

[0002] The existing method for preventing mine vehicles from slipping involves manually placing triangular blocks between the tires and the ground. Because this is a manual operation, there is a risk of omissions or incorrect placement, and the triangular blocks may be lost during vehicle operation, which is detrimental to vehicle parking safety.

[0003] Chinese utility model patent CN211898019U discloses a slope blocking device for mining vehicles, including a blocking gate, a rotating shaft, a hydraulic cylinder, a clean water pipe, and a drainage pipe. One end of the blocking gate is movably connected to the rotating shaft, which is located on one side of the track. The hydraulic cylinder is connected to the blocking gate. The clean water pipe is connected to the inlet of the hydraulic cylinder, and the drainage pipe is connected to the outlet of the hydraulic cylinder. The hydraulic cylinder is fixed on the side where the blocking gate is connected to the rotating shaft. The device also includes a water pipe. Both the clean water pipe and the drainage pipe are connected to the hydraulic cylinder through the water pipe. A shut-off valve is provided between the clean water pipe and the water pipe. The device also includes a stop rod, which is attached to the other end of the blocking gate. The output shaft of the hydraulic cylinder acts on the blocking gate, and there is a suitable distance between the point of action and the axis of the rotating shaft.

[0004] The aforementioned technologies have the following drawbacks: braking mining vehicles using a stop gate can only be achieved at locations where a stop gate is installed. Braking is not possible at locations where a stop gate is not installed, thus limiting the braking position of mining vehicles and resulting in low safety. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] This utility model provides a hydraulic automatic vehicle-stopping device, installed on a trackless rubber-tired vehicle, the structure of which is as follows: Figure 1 - Figure 3 As shown, it includes a support 1, a connecting rod 2, a wheel stop block 3, and a drive mechanism 4.

[0027] The support 1 is connected to the frame of the trackless rubber-tired vehicle.

[0028] One end of the connecting rod 2 is rotatably connected to the support 1.

[0029] The wheel stop block 3 is connected to the end of the connecting rod 2 away from the support 1.

[0030] The fixed end of the drive mechanism 4 is connected to the support 1, and the movable end of the drive mechanism 4 is rotatably connected to the connecting rod 2. The drive mechanism 4 is used to drive the connecting rod 2 to rotate so that the vehicle blocking block 3 contacts or disengages from the wheel 5 and bottom surface of the trackless rubber-tired vehicle.

[0031] In use, when braking of the trackless rubber-tired vehicle is required, the drive mechanism 4 starts to operate. The movement of the movable end of the drive mechanism 4 causes the connecting rod 2 to rotate. As the connecting rod 2 rotates, the braking block 3 is moved towards the position between the wheel 5 and the road surface 6. When the braking block 3 is moved between the wheel 5 and the road surface 6 and comes into contact with it, friction is generated. This friction prevents the wheel 5 from continuing to roll, thereby achieving braking of the trackless rubber-tired vehicle.

[0032] In this invention, compared to the traditional method of using a door stop for braking, the brake block 3 is directly mounted on the vehicle frame. The brake block 3 is brought into contact with the wheel 5 and the road surface 6 by the drive mechanism 4 to achieve braking. This method is not limited by position and improves the flexibility and timeliness of braking.

[0033] To achieve efficient braking, please refer to... Figure 1 In a preferred embodiment, the vehicle blocking device further includes a slide rod 21, which is slidably connected to the connecting rod 2 along the length direction of the connecting rod 2, and the vehicle blocking block 3 is connected to the end of the slide rod 21 away from the connecting rod 2.

[0034] During operation, as the connecting rod 2 rotates, the sliding rod 21 can slide along the length of the connecting rod 2. This sliding function allows the brake block 3 to precisely adjust its relative position to the wheel 5 and the road surface 6 according to actual conditions. Through the sliding adjustment of the sliding rod 21, the brake block 3 can ultimately accurately abut against the wheel 5 and the road surface 6. After the brake block 3 comes into close contact with the wheel 5 and the road surface 6, friction is generated, thereby preventing the wheel 5 from continuing to roll and achieving braking.

[0035] To achieve precise length adjustment of link 2, please refer to... Figure 2 In a preferred embodiment, the vehicle blocking device further includes a slider 22, the slider 21 is sleeved on the connecting rod 2, the slider 22 is connected to the slider 21, the connecting rod 2 is provided with a groove 23, and the slider 22 is located in the groove 23.

[0036] In use, the groove 23 provides a clear movement trajectory for the slider 22, so that the slider 21 can only slide along the length of the connecting rod 2, ensuring that the vehicle blocking block 3 can accurately reach the predetermined position when it is close to the wheel 5 and the road surface 6, thus improving the accuracy and reliability of the device.

[0037] To ensure a tighter fit between the wheel stop block 3 and the wheel 5, please refer to... Figure 3 In a preferred embodiment, the vehicle blocking device further includes a tension spring 24, one end of which is connected to the connecting rod 2 and the other end of which is connected to the sliding rod 21. When the tension spring 24 is in a stretched state, the tension spring 24 causes the vehicle blocking block 3 to tend to slide towards the wheel 5 of the trackless rubber-tired vehicle.

[0038] During use, as the slide bar 21 moves between the wheel 5 and the road surface 6, the tension of the tension spring 24 always acts on the slide bar 21, helping it overcome possible resistance, such as the friction between the slider 22 and the groove 23, allowing the brake block 3 to move more smoothly and quickly towards the wheel 5. When the brake block 3 moves between the wheel 5 and the road surface 6 and comes into contact with it, the tension of the tension spring 24 makes the brake block 3 fit more tightly against the wheel 5 and the road surface 6, increasing the pressure between the brake block 3 and the wheel 5 and the road surface 6, thereby increasing the friction and more effectively preventing the wheel 5 from rolling, thus achieving braking of the trackless rubber-wheeled vehicle.

[0039] To increase the friction between the wheel stop 3, the wheel 5, and the road surface 6, please refer to... Figure 3 In a preferred embodiment, the vehicle blocking block 3 has a first contact surface 31 and a second contact surface 32. The first contact surface 31 is used to contact the wheel 5 of the trackless rubber-tired vehicle, and the second contact surface 32 is used to contact the road surface 6 of the trackless rubber-tired vehicle.

[0040] During use, the contact surface 31 with the wheel 5 and the contact surface 32 with the road surface 6 increase the contact area between the wheel block 3 and the wheel 5 and the road surface 6, thereby increasing the friction.

[0041] To make the sliding of the brake block 3 smoother, please refer to... Figure 3 In a preferred embodiment, the first contact surface 31 and the second contact surface 32 have a smooth transition.

[0042] When in use, the smooth transition of the wheel stop block 3 between the wheel 5 and the road surface 6 helps it to make smoother contact with both the wheel 5 and the road surface 6. It will not cause jamming or jumping due to abrupt changes in the contact surface, making the wheel stop process smoother, reducing the impact on the vehicle and the road surface 6, and also reducing noise.

[0043] To ensure that the wheel stop block 3 adapts to the angle between the wheel 5 and the road surface 6, please refer to... Figure 3 In a preferred embodiment, the brake block 3 is rotatably connected to the end of the slide bar 21 away from the connecting rod 2.

[0044] During use, the angle between the wheel 5 and the road surface 6 may change due to factors such as the vehicle's driving posture and the condition of the road surface 6. The wheel-stopping block 3 is rotatably connected to the slide rod 21, and can automatically adjust its posture according to the actual angle between the wheel 5 and the road surface 6, ensuring that the first contact surface 31 can always contact the wheel 5 at the optimal angle, and the second contact surface 32 fits well with the road surface 6, thereby effectively improving the wheel-stopping effect.

[0045] To move the brake block 3, please refer to... Figure 3In a preferred embodiment, the drive mechanism 4 includes an electronically controlled valve 41 and a hydraulic cylinder 42. The electronically controlled valve 41 is mounted on a support 1, the cylinder body of the hydraulic cylinder 42 is rotatably connected to the support 1, the piston rod of the hydraulic cylinder 42 is rotatably connected to a connecting rod 2, and the electronically controlled valve 41 is electrically connected to the hydraulic cylinder 42.

[0046] In operation, after receiving a signal, the electronically controlled valve 41 allows pressurized oil to enter the cylinder 42. Once the pressurized oil enters the cylinder 42, it pushes the piston rod to extend. The movement of the piston rod is transmitted to the connecting rod 2 through the rotating connection point, causing the connecting rod 2 to rotate around the connection point with the support 1. The rotation of the connecting rod 2 then drives the sliding rod 21 to move through the slider 22, thereby extending the brake block 3.

[0047] To achieve a fast response from brake block 3, please refer to... Figure 3 In a preferred embodiment, the electronic controller on the engine is electrically connected to the electronically controlled valve 41.

[0048] When the engine is started, the electronic controller can automatically send an electrical signal to the electronic control valve 41 based on the information fed back by the built-in program. After receiving the signal, the electronic control valve 41 can control the action of the hydraulic cylinder 42 in a timely manner, thereby improving the safety of vehicle operation.

[0049] For automatic reset of the vehicle blocking block 3, please refer to... Figure 3 In a preferred embodiment, the drive mechanism 4 further includes a return spring 43, one end of which is rotatably connected to the support 1, and the other end of which is rotatably connected to the connecting rod 2. The return spring 43 is in a stretched state, and the return spring 43 causes the wheel block 3 to tend to rotate toward the wheel 5 of the trackless rubber-tired vehicle.

[0050] In use, when the brake needs to be released, the hydraulic cylinder 42 drives the brake block 3, which moves away from the wheel 5 and the road surface 6, and the return spring 43 is stretched. When braking is needed, the hydraulic cylinder 42 stops operating, and under the restoring force of the return spring 43, the brake block 3 rotates to a position between the wheel 5 and the road surface 6, thus achieving braking.

[0051] To better understand this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of a hydraulic automatic vehicle braking device according to this utility model is described in detail as follows: When braking of a trackless rubber-tired vehicle is required, the drive mechanism 4 starts to work. The movement of the movable end of the drive mechanism 4 causes the connecting rod 2 to rotate. As the connecting rod 2 rotates, the braking block 3 is moved towards the position between the wheel 5 and the road surface 6. When the braking block 3 is moved between the wheel 5 and the road surface 6 and comes into contact with it, friction is generated. This friction prevents the wheel 5 from continuing to roll, thereby achieving braking of the trackless rubber-tired vehicle.

[0052] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
