Description

Technical Field

[0001] This application relates to the technical field of caulking equipment, and in particular to an automatic caulking device for articulated material carts. Background Technology

[0002] In high-risk material transportation operations such as mines or loading and unloading yards, work vehicles need to be parked at fixed locations to facilitate loading and unloading by workers. In order to keep the work vehicles in place at the work location, a chock device is often used to fix the position of the work vehicles and prevent them from accidentally sliding or rolling away.

[0003] Due to the uncertainty of the work location, it is often necessary to fix the work vehicle in work locations with varying slopes or uneven ground. Existing camouflage devices are difficult to achieve precise positioning, which leads to poor contact between the camouflage device and the ground, making the work vehicle prone to sliding or slipping. Summary of the Invention

[0004] In order to improve the stability of the cambering device in contact with the ground and reduce the risk of the working vehicle sliding or overturning, this application provides an articulated automatic cambering device for material carts.

[0007] Mounting bracket;

[0008] A fixing assembly is mounted on the mounting bracket. The fixing assembly includes a first fixing member and a second fixing member. The first fixing member includes:

[0009] A telescopic rod, the fixed end of which is hinged to the mounting bracket;

[0010] A first fixing block is fixedly installed on the movable end of the telescopic rod;

[0013] The second fixing block is inserted through the bottom wall of the first fixing block and is fixedly connected to the connecting rod.

[0014] A drive assembly is connected to the fixed assembly. The drive assembly can first drive the first fixed block to move and make the first fixed block abut against the wheel. Then, the drive assembly can drive the second fixed block to move and make the second fixed block abut against the ground.

[0015] Optionally, the driving component includes:

[0016] A guide block is fixedly installed inside the fixed end of the telescopic rod, and a guide groove is provided inside the guide block;

[0017] A chain, which is slidably installed in the guide groove, with one end of the chain abutting against the connecting rod;

[0018] A push rod is slidably installed in the guide groove and is fixedly connected to the end of the chain away from the connecting rod.

[0019] A driving component is connected to the push rod, and the driving component is capable of pushing the push rod to slide within the guide groove.

[0020] Optionally, the driving component is a hydraulic cylinder, with the fixed end of the hydraulic cylinder hinged to the mounting bracket, and the movable end of the hydraulic cylinder hinged to the end of the push rod away from the chain.

[0021] Optionally, the driving component further includes:

[0022] A sliding groove is formed through the guide block and communicates with the guide groove;

[0023] The slider is slidably installed in the groove and is fixedly connected to the push rod.

[0024] Optionally, the first fastener may further include a first spring;

[0025] One end of the first spring is fixedly connected to the connecting rod, and the other end of the first spring is fixedly installed inside the fixed end of the telescopic rod. The first spring always applies a force to the connecting rod in the direction close to the chain.

[0026] Optionally, the first fixing member further includes a second spring, one end of which is fixedly connected to the fixed end of the telescopic rod, and the other end of which is fixedly connected to the movable end of the telescopic rod. The second spring always applies a force to the movable end of the telescopic rod away from the fixed end of the telescopic rod.

[0027] Optionally, the first fixing member further includes a limiting member, the limiting member comprising:

[0028] A positioning plate is fixedly installed inside the fixed end of the telescopic rod, and the positioning plate is fixedly connected to the end of the first spring away from the connecting rod.

[0029] A limiting rod, one end of which is fixedly installed on the positioning plate, and the other end of which passes through the first fixing member;

[0030] A limiting block is fixedly installed on the end of the limiting rod away from the positioning plate.

[0031] Optionally, the limiting rod is a screw;

[0033] Optionally, one side of the first fixing block is an arc surface, used to fit the wheel.

[0034] Optionally, the bottom of the second fixing block is provided with a wear-resistant and anti-slip layer.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. After the work vehicle stops at the work site, the fixing component is used to open the chock on the work vehicle. The drive component moves the first fixing block and the second fixing block, so that the first fixing block abuts against the wheel and the bottom of the second fixing block abuts against the ground. The friction between the first fixing block and the wheel prevents the wheel from rotating, and the friction between the second fixing block and the ground prevents the second fixing block from sliding on the ground, thereby preventing the work vehicle from sliding on the ground. The combined effect of these two factors improves the stability of the fixing component in contact with the ground, further enhancing the chocking stability of the articulated material car automatic chocking device.

[0037] 2. The drive component works and drives the fixed component to work, ensuring that during the operation of the articulated material car automatic camouflage device on the working vehicle, the first fixed block first abuts against the wheel and then the second fixed block abuts against the ground. This ensures that during the rotation of the telescopic rod, the second fixed block will not slide prematurely and interfere with the ground, thus affecting the normal rotation of the telescopic rod.

[0038] 3. The driving component drives the telescopic rod to rotate via the guide block, thereby resetting the telescopic rod. The slider slides within the groove to ensure that the second fixing block can be retracted into the first fixing block before the telescopic rod rotates back to its original position. This ensures that the second fixing block will not interfere with the ground during the telescopic rod's rotation and reset process, thus improving the operational stability of the fixing component structure.

[0048] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0049] This application discloses an automatic cover-up device for articulated material carts.

[0050] Reference Figure 1 An articulated material cart automatic cover-up device includes a mounting bracket 1, a fixing component 2, and a drive component 3.

[0051] Mounting bracket 1 is fixedly installed on the work vehicle. Fixing component 2 and driving component 3 are installed on mounting bracket 1, and fixing component 2 is connected to driving component 3. Driving component 3 is used to drive fixing component 2 to work.

[0052] Reference Figure 2 and Figure 3 The fixing component 2 includes a first fixing member 21 and a second fixing member 22.

[0053] The first fixing component 21 includes a telescopic rod 211 and a first fixing block 212. The fixed end of the telescopic rod 211 is hinged to the mounting bracket 1, and the first fixing block 212 is fixedly installed on the movable end of the telescopic rod 211. One side of the first fixing block 212 is an arc surface, which can fit tightly with the wheel. The drive assembly 3 can push the first fixing block 212 to move, so that the first fixing block 212 abuts against the wheel.

[0054] The second fixing component 22 includes a connecting rod 221 and a second fixing block 222. The connecting rod 221 passes through the telescopic rod 211, and one end of the connecting rod 221 passes through and slides within the first fixing block 212. The connecting rod 221 is fixedly connected to the second fixing block 222, which passes through the bottom wall of the first fixing block 212. The bottom of the second fixing block 222 is provided with a wear-resistant and anti-slip layer. The driving assembly 3 can push the second fixing block 222 to move, so that the bottom of the second fixing block 222 abuts against the ground.

[0055] In the initial state, the first fixing block 212 moves away from the wheel under the action of the drive component 3, and the second fixing block 222 is embedded in the first fixing block 212.

[0056] After the work vehicle is parked at the work site, the fixing component 2 is used to cover the work vehicle. By controlling the drive component 3, the drive component 3 is made to work and drive the first fixing block 212 and the second fixing block 222 to move.

[0057] When the ground at the work site is flat, under the drive of the drive assembly 3, one side of the first fixing block 212 abuts against the wheel, the bottom surface of the first fixing block 212 abuts against the ground, and the bottom surface of the second fixing block 222 is flush with the bottom surface of the first fixing block 212 and abuts against the ground.

[0058] When the ground at the work site is uneven, the connecting rod 221 can slide within the first fixing block 212, thereby causing the second fixing block 222 to slide on the bottom wall of the first fixing block 212, allowing the bottom height of the second fixing block 222 to be adjusted. The sliding of the connecting rod 221 allows the second fixing block 222 to protrude from or be recessed within the bottom wall of the first fixing block 212, ensuring that the second fixing block 222 can be firmly pressed against the concave or convex ground, improving the adaptability of the fixing assembly 2 to different ground conditions.

[0059] After the first fixing block 212 comes into contact with the wheel, the friction between the first fixing block 212 and the wheel prevents the wheel from rotating. After the second fixing block 222 comes into contact with the ground, the friction between the second fixing block 222 and the ground prevents the second fixing block 222 from sliding on the ground, thereby preventing the working vehicle from sliding on the ground. The combined effect of the two improves the stability of the fixing component 2 in contact with the ground, and further improves the cambering stability of the articulated material car automatic cambering device on the wheel.

[0060] Reference Figure 3 and Figure 4 The drive assembly 3 includes a guide block 31, a chain 32, a push rod 33, and a drive component 34. The guide block 31 is fixedly installed inside the fixed end of the telescopic rod 211. A guide groove 311 is formed within the guide block 31, which is divided into a first guide section, a second guide section, and a third guide section. The guide directions of the first and third guide sections are perpendicular to each other. The guide direction of the second guide section is an arc, used to connect the first and third guide sections. The guide direction of the third guide section is the same as the sliding direction of the connecting rod 221 within the first fixed block 212. The chain 32 is slidably installed within the guide groove 311, with one end abutting against the connecting rod 221. The push rod 33 is slidably installed within the guide groove 311, sliding within the first guide section of the guide groove 311. The push rod 33 is fixedly connected to the end of the chain 32 away from the connecting rod 221. The push rod 33 is connected to the drive component 34, which can push the push rod 33 to slide within the guide groove 311.

[0061] Reference Figure 3 and Figure 4 The first fixing member 21 also includes a first spring 213. One end of the first spring 213 is fixedly connected to the connecting rod 221, and the other end of the first spring 213 is fixedly installed in the fixed end of the telescopic rod 211. The first spring 213 always applies a force to the connecting rod 221 in the direction close to the chain 32.

[0062] The drive component 3 works and drives the fixed component 2 to work. The drive component 34 works and pushes the push rod 33 to slide in the guide groove 311, so that the chain 32 moves in the guide groove 311 towards the connecting rod 221 until the chain 32 and the connecting rod 221 are pressed together.

[0063] After the chain 32 abuts against the connecting rod 221, the drive member 34 continues to push the push rod 33 to slide. Since the first spring 213 applies a preload to the connecting rod 221, when the drive member 34 pushes the push rod 33 to move, it will first push the fixed end of the telescopic rod 211 to rotate, so that the first fixed block 212 abuts against the wheel.

[0064] Afterwards, the drive member 34 continues to push the push rod 33 to slide. The pushing force of the drive member 34 on the push rod 33 overcomes the preload force applied by the first spring 213 to the connecting rod 221, causing the push rod 33 to continue to slide. It also pushes the connecting rod 221 away from the guide block 31 through the chain 32, thereby driving the second fixed block 222 to move synchronously, so that the bottom of the second fixed block 222 is pressed against the ground.

[0065] During the movement of the connecting rod 221, the length of the first spring 213 is compressed. By setting the first spring 213 with preload, it is ensured that during the cambering process, the cambering can be performed in the following order: the first fixing block 212 first contacts the wheel, and then the second fixing block 222 contacts the ground. This prevents the second fixing block 222 from sliding prematurely and interfering with the ground during the rotation of the telescopic rod 211, thus affecting the normal rotation of the telescopic rod 211.

[0066] When the camouflage operation on the work vehicle is completed, the drive unit 34 is operated. The drive unit 34 works and drives the push rod 33 to move away from the connecting rod 221. The first spring 213 gradually returns to its original length. The connecting rod 221 drives the second fixing block 222 to move closer to the guide block 31 until the second fixing block 222 is retracted. Then the drive unit 34 continues to work, causing the telescopic rod 211 to rotate until the first fixing block 212 is retracted. This ensures that after the camouflage operation is completed, the second fixing block 222 can be retracted first, followed by the first fixing block 212. This ensures that the second fixing block 222 will not rub against the ground during the rotation of the telescopic rod 211, thus extending the service life of the second fixing block 222.

[0067] Reference Figure 2 Furthermore, the drive component 34 is a hydraulic cylinder, the length of which can be adjusted by remote electrical control. A hydraulic lock is installed on the hydraulic cylinder, which enables the hydraulic cylinder to have a self-locking function. The fixed end of the hydraulic cylinder is hinged to the mounting bracket 1, and the movable end of the hydraulic cylinder is hinged to the end of the push rod 33 away from the chain 32.

[0068] When the work vehicle is being covered, the movable end of the hydraulic cylinder is extended to push the push rod 33 towards the connecting rod 221. After the covering work is finished, the movable end of the hydraulic cylinder is shortened to push the push rod 33 away from the connecting rod 221. The change in the length of the movable end of the hydraulic cylinder drives the first fixed block 212 and the second fixed block 222 to move, improving the ease of operation of the fixing component 2.

[0069] Reference Figure 3 and Figure 5Furthermore, the drive assembly 3 also includes a slide groove 312 and a slider 35. The slide groove 312 is formed through the guide block 31 and communicates with the guide groove 311. The slider 35 is slidably installed in the slide groove 312 and is fixedly connected to the push rod 33.

[0070] When the masking begins, the drive unit 34 drives the push rod 33 to move towards the connecting rod 221, and the push rod 33 simultaneously drives the slider 35 to slide from the beginning end to the end end of the slide groove 312.

[0071] When the camouflage operation is completed and the telescopic rod 211 needs to be reset, the drive member 34 drives the push rod 33 to move away from the connecting rod 221. The movement of the push rod 33 then drives the slider 35 to slide synchronously within the groove 312 until the slider 35 abuts against the starting end of the groove 312. After that, the drive member 34 continues to drive the push rod 33 to move. The push rod 33, through the cooperation of the slider 35 and the groove 312, drives the guide block 31 to move. The drive member 34, through the guide block 31, drives the telescopic rod 211 to rotate, thus resetting the telescopic rod 211. By sliding the slider 35 within the groove 312, it is ensured that the second fixing block 222 can be retracted into the first fixing block 212 in advance before the telescopic rod 211 rotates back to reset. This ensures that the second fixing block 222 will not interfere with the ground during the rotation and reset process of the telescopic rod 211, thus affecting the normal rotation of the telescopic rod 211 and improving the structural stability of the fixing component 2.

[0072] Reference Figure 3 The first fixing member 21 also includes a second spring 214. One end of the second spring 214 is fixedly connected to the fixed end of the telescopic rod 211, and the other end of the second spring 214 is fixedly connected to the movable end of the telescopic rod 211. The second spring 214 always applies a force to the movable end of the telescopic rod 211 in a direction away from the fixed end of the telescopic rod 211.

[0073] Reference Figure 3 The first fixing member 21 also includes a limiting member 215, which includes a positioning plate 2151, a limiting rod 2152 and a limiting block 2153.

[0074] The positioning plate 2151 is fixedly installed inside the fixed end of the telescopic rod 211. The positioning plate 2151 is fixedly connected to the end of the first spring 213 away from the connecting rod 221, so that the end of the first spring 213 away from the connecting rod 221 is fixedly installed inside the fixed end of the telescopic rod 211. One end of the limiting rod 2152 is fixedly installed on the positioning plate 2151, and the other end of the limiting rod 2152 passes through the first fixing member 21. The limiting block 2153 is fixedly installed on the end of the limiting rod 2152 away from the positioning plate 2151.

[0075] Under the action of the second spring 214 and the limiting member 215, the length of the telescopic rod 211 is limited to prevent the telescopic rod 211 from being too long, which would cause the first fixing block 212 to come into contact with the ground and rub against it during the rotation of the telescopic rod 211, thereby extending the service life of the first fixing block 212.

[0076] Furthermore, the limiting rod 2152 is a screw, and the limiting block 2153 is a nut. The limiting block 2153 is coaxially sleeved and threadedly connected to the limiting rod 2152.

[0077] By rotating the limiting block 2153, the position of the limiting block 2153 on the screw can be adjusted, thereby adjusting the limiting length of the limiting component 215, and thus adjusting the telescopic length of the telescopic rod 211. This allows the fixing component 2 to adapt to different height usage scenarios, ensuring that the telescopic rod 211 can rotate normally under different height usage scenarios, and improving the adaptability of the articulated material cart automatic cover-up device.

[0078] The implementation principle of the articulated material cart automatic cambering device in this application embodiment is as follows: After the working vehicle stops at the work site, the fixing component 2 is used to camber the working vehicle. The drive component 3 drives the first fixing block 212 and the second fixing block 222 to move, so that the first fixing block 212 abuts against the wheel and the bottom of the second fixing block 222 abuts against the ground. The friction between the first fixing block 212 and the wheel prevents the wheel from rotating, and the friction between the second fixing block 222 and the ground prevents the second fixing block 222 from sliding on the ground, thereby preventing the working vehicle from sliding on the ground. The combined effect of the two improves the stability of the contact between the fixing component 2 and the ground, further improving the cambering stability of the articulated material cart automatic cambering device.

[0079] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
