Description

Technical Field

[0001] This application generally relates to the field of vehicle safety braking technology, and specifically to a tank truck braking device. Background Technology

[0002] To prevent tank trucks from rolling away due to braking system malfunctions during parking operations, wheel chocks are installed at the front and rear undersides of the wheels. Currently, most existing wheel chocks are manually operated, requiring operators to manually place them in designated positions. When loading or unloading toxic, corrosive acid or alkali solutions or volatile media, operators are directly exposed to a hazardous environment and are susceptible to harm from harmful substances. This operating method poses safety hazards. Furthermore, if the vehicle suddenly moves during operation, it may cause collision damage to personnel and surrounding facilities. Although a small number of automatic wheel chocks exist, they generally suffer from complex structures, cumbersome control, and inconvenient use. For example, some automatic wheel chocks use a three-axis, two-link structure, requiring three drive devices at the connecting shafts to work together to complete the wheel-stopping action. This not only increases the manufacturing cost and maintenance difficulty of the equipment but may also introduce errors due to the coordinated operation of multiple drives, affecting the reliability of the wheel-stopping action.

[0003] Therefore, this application provides a tank truck blocking device that is simple in structure, easy to operate, and occupies little space when not in operation. Utility Model Content

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] This application provides a tanker truck blocking device, comprising:

[0026] The support mechanism 1 includes a first driving device 2 and a mounting component 3. The first driving device 2 drives the mounting component 3 to move along a first direction, which is the length direction of the support mechanism.

[0027] The drive adjustment mechanism 4 includes a second drive device 5, a first linkage component 6, and a second linkage component 7. One end of the first linkage component 6 is hinged to the mounting component 3, and the other end is connected to the second linkage component 7 through the transmission component 8. The connecting end of the second drive device 5 is hinged to the mounting component 3, and the driving end of the second drive device 5 is hinged to the first linkage component 6.

[0028] The limiting mechanism 9 is connected to the second linkage component 7 so that the second driving device 5 drives the limiting mechanism 9 to move along the second direction to the space between the wheels of the vehicle to be blocked through the first linkage component 6 and the second linkage component 7. The second direction is perpendicular to the first direction.

[0029] It should be noted that the supporting mechanism 1 includes a first driving device 2 and a mounting assembly 3, such as... Figure 1As shown, when performing a vehicle blocking operation on a tanker truck, the tanker truck must first be parked in a parking space, with the wheels to be blocked positioned next to the blocking device. After activating the blocking device, the first drive device 2 drives the mounting assembly 3 to move along a first direction (the length direction of the bearing mechanism 1) to a position corresponding to the wheels of the tanker truck to be blocked. For example, the first drive device 2 can be an electric slide rail. At this time, the second drive device 5 of the drive adjustment mechanism 4 provides power, for example, the second drive device 5 can be a servo push rod, pushing the first linkage assembly 6 to rotate around the hinge point between the mounting assembly 3 and the first linkage assembly 6. The second drive device 5 also rotates around the hinge point between the mounting assembly 3 and the second drive device 5. The first linkage assembly 6 drives the second linkage assembly 7 to move towards the wheels to be blocked through the transmission assembly 8. During this process, the limiting mechanism 9 moves in an arc trajectory towards the wheels to be blocked under the drive of the second linkage assembly 7, so that the limiting mechanism 9 moves between the wheels to be blocked, thus completing the blocking of the wheels. Here, the main purpose of the second driving device 5 is to drive the limiting mechanism 9 to move toward the gap between the wheels of the vehicle to be blocked, so as to adjust the distance between the limiting mechanism 9 and the wheel of the vehicle to be blocked. The second direction is perpendicular to the first direction, that is, the width direction of the bearing mechanism 1. The so-called arc trajectory means that when the second driving device 5 drives the limiting mechanism 9 to move toward the wheel of the vehicle to be blocked through the first linkage component 6, the transmission component 8, and the second linkage component 7, the height position of the limiting mechanism 9 will also change synchronously, so the final movement trajectory of the limiting mechanism 9 is arc-shaped.

[0030] In the supporting mechanism 1, the first driving device 2 provides power for the movement of the mounting component 3, enabling it to move along a first direction. This allows the mounting component 3 to be adjusted according to the parking position of the tanker truck in the parking space. The mounting component 3 also provides support and a base for the drive adjustment mechanism 4 and the limiting mechanism 9. When the mounting component 3 moves along the first direction, it can drive the drive adjustment mechanism 4 and the limiting mechanism 9 to the position corresponding to the wheels of the vehicle to be blocked. The drive adjustment mechanism 4 includes a second driving device 5, a first linkage component 6, and a second linkage component 7. The connecting end of the second driving device 5 is hinged to the mounting component 3, and the driving end is hinged to the first linkage component 6. One end of the first linkage component 6 is hinged to the mounting component 3, and the other end is connected to the second linkage component 7 through a transmission component 8. On one hand, the mounting component... 3 provides a supporting foundation for the second drive device 5. On the other hand, the second drive device 5 can drive the first linkage component 6 to rotate around the hinge point between the mounting component 3 and the first linkage component 6 towards the wheel to be blocked, and then drive the second linkage component 7 to move closer to the wheel to be blocked through the transmission component 8. The limiting mechanism 9 is connected to the second linkage component 7 as a direct blocking component. Under the drive of the second linkage component 7, the limiting mechanism 9 can move between the wheels to be blocked, effectively blocking the wheels. After the blocking process is completed, the second drive device 5 drives the first linkage component 6 to rotate around the hinge point between the mounting component 3 and the first linkage component 6 towards the bearing mechanism 1. The first linkage component 6 drives the second linkage component 7 to move towards the bearing mechanism 1 through the transmission component 8, and then retracts the limiting mechanism 9 to return to the initial position. This device has a simple structure and is easy to operate. The blocking function can be achieved by driving multiple linkages with only a single drive device, which reduces the manufacturing cost and maintenance difficulty of the equipment. In addition, while reducing the number of drive devices, it eliminates the error influence that may be caused by the coordinated operation of multiple drives, and improves the reliability of the blocking action.

[0031] Furthermore, the mounting assembly 3 includes a sliding base 10 and a support member 11. The sliding base 10 is slidably connected to the first driving device 2 and is used to drive the sliding base 10 to slide along a first direction. The support member 11 extends along a third direction and is fixedly connected to the sliding base 10. The third direction is perpendicular to the first direction. One end of the support member 11 away from the sliding base 10 is hinged to the connection end of the second driving device 5.

[0032] It should be noted that the sliding base 10 and support 11 of the mounting component 3 provide a stable mounting support foundation for the drive adjustment mechanism 4. The bottom of the sliding base 10 is also provided with a guide rail slider 21 that is slidably connected to the first drive device 2. When the first drive device 2 drives the sliding base 10 to move along the first direction, it drives the support 11, the drive adjustment mechanism 4 and the limiting mechanism 9 to move synchronously, thereby realizing the position adjustment of the entire vehicle blocking device and ensuring that the position of the limiting mechanism 9 corresponds to the position of the wheel to be blocked. The support 11 extends along a third direction (the third direction is perpendicular to the first direction), with one end fixedly connected to the sliding base 10 and the other end hinged to the connecting end of the second drive device 5. On the one hand, it provides support for the second drive device 5, and on the other hand, when the drive end of the second drive device 5 extends or retracts, the connecting end of the second drive device 5 can rotate around the hinge point with the support 11.

[0033] Furthermore, the mounting component 3 also includes a first connecting seat 12 disposed on the sliding base 10, the first connecting seat 12 being fixedly connected to the sliding base 10, and the first linkage component 6 being hinged to the first connecting seat 12.

[0034] It should be noted that the first connecting seat 12, as the connecting component between the sliding base 10 and the first linkage component 6, has an overall "U" shaped structure and two hinge points along the width direction of the bearing mechanism 1, so that the first linkage component 6 can rotate around the two hinge points with the first connecting seat 12, while the fixed connection with the sliding base 10 provides support for the first linkage component 6 to rotate around the hinge points with the first connecting seat 12.

[0035] Furthermore, the first linkage assembly 6 includes two parallel first links 13 and a second link 14. The two ends of the second link 14 are respectively hinged to the ends of the two first links 13 away from the bearing mechanism 1. The ends of the first links 13 near the bearing mechanism 1 are hinged to the first connecting seat 12. The two first links 13, the second link 14 and the first connecting seat 12 together form a parallelogram structure. One of the first links 13 is hinged to the telescopic end of the second drive device 5.

[0036] It should be noted that the first linkage component 6 forms a parallelogram structure with the first connecting seat 12 through two parallel first connecting rods 13 and second connecting rods 14: the two first connecting rods 13 are parallel and of the same length, and the ends closer to the bearing mechanism 1 are hinged to the first connecting seat 12 to form the two bottom support points of the parallelogram, and the ends farther away from the bearing mechanism 1 are hinged to the second connecting rods 14 to form the top edge of the parallelogram, so that the second connecting rods 14 can move toward the wheel of the vehicle to be blocked. Among them, the first link 13 near the limiting mechanism 9 is hinged to the driving end of the second driving device 5 and the end of the second link 14 near the limiting mechanism 9, and the other end of the first link 13 away from the limiting mechanism 9 is hinged to the other end of the second link 14 away from the limiting mechanism 9. When the driving end of the second driving device 5 extends, it will push the first link 13 near the limiting mechanism 9 to rotate around the hinge point with the first connecting seat 12 toward the wheel of the vehicle to be blocked. Due to the constraint of the parallelogram structure, the first link 13 away from the limiting mechanism 9 will rotate synchronously and in the same direction, thereby driving the second link 14 to move toward the wheel of the vehicle to be blocked. At the same time, through the action of the transmission component 8, the second linkage component 7 is driven to move toward the wheel of the vehicle to be blocked, thereby pushing the limiting mechanism 9 to move between the wheels of the vehicle to be blocked.

[0037] Furthermore, the second linkage assembly 7 includes two parallel third links 15. One end of the third link 15 is connected to the first link 13 via a transmission assembly 8, and the other end is hinged to a second connecting seat 16. The two third links 15, the second link 14, and the second connecting seat 16 together form a parallelogram structure.

[0038] It should be noted that the two third links 15 are of the same length and parallel to each other. One end of the two third links 15 is rotatably connected to the ends of the two first links 13 away from the bearing mechanism 1 and the two ends of the second link 14, so that the two third links 15 can rotate towards the wheel of the vehicle to be blocked under the drive of the transmission assembly 8. The other end of the two third links 15 is hinged to the second connecting seat 16. The second connecting seat 16 is "L" shaped and has two hinge points along the width direction of the bearing mechanism 1, so that the two third links 15 can rotate around the two hinge points of the second connecting seat 16. Combined with the second link 14 in the first linkage assembly 6, it forms a "double parallelogram" transmission structure with the first linkage assembly 6, pushing the second connecting seat 16 to move towards the gap between the wheels of the vehicle to be blocked, so that the limiting mechanism 9 connected to the second connecting seat 16 can move between the wheels of the vehicle to be blocked.

[0039] Furthermore, the transmission assembly 8 includes two meshing sector gears 17 and two connecting shafts 22. The two sector gears 17 are keyed to the two connecting shafts 22 respectively. The first connecting rod 13 near the limiting mechanism 9 and the third connecting rod 15 away from the limiting mechanism 9 are fixedly connected to the two connecting shafts 22 respectively. When the first linkage assembly 6 moves under the action of the second driving device 5, it drives the second linkage assembly 7 to move through the meshing transmission of the two sector gears 17, thereby pushing the limiting mechanism 9 to move along the second direction.

[0040] It should be noted that one of the sector gears 17 is keyed to the connecting shaft 22 near the limiting mechanism 9, and the connecting shaft 22 is fixedly connected to the first connecting rod 13 near the limiting mechanism 9. The other sector gear 17 is keyed to the connecting shaft 22 away from the limiting mechanism 9, and the connecting shaft 22 is fixedly connected to the third connecting rod 15 away from the limiting mechanism 9. One of the connecting shafts 22 passes through the second connecting rod 14, the first connecting rod 13 near the limiting mechanism 9, and the third connecting rod 15 near the limiting mechanism 9 in sequence. The other connecting shaft passes through the third connecting rod 15 away from the limiting mechanism 9, the first connecting rod 13 away from the limiting mechanism 9, and the second connecting rod 14 in sequence. When the second drive device 5 drives the first link 13 near the limiting mechanism 9 to rotate around the hinge point with the mounting assembly 3 toward the wheel to be blocked, it will drive the sector gear 17 near the limiting mechanism 9 to rotate synchronously, and through the meshing relationship, drive the sector gear 17 away from the limiting mechanism 9 to rotate in the opposite direction, thereby driving the two third links 15 to rotate around the connecting axis toward the wheel to be blocked, and driving the second connecting seat 16 to move toward the gap between the wheels to be blocked, pushing the limiting mechanism 9 along the second direction between the wheels to be blocked; Figure 2 As shown, when the second drive device 5 drives the first linkage assembly 6 to move away from the wheel of the vehicle to be blocked, the sector gear 17 close to the limiting mechanism 9 will rotate in the opposite direction synchronously with the first connecting rod 13, and through the meshing relationship, drive the sector gear 17 away from the limiting mechanism 9 to rotate in the forward direction, thereby driving the two third connecting rods 15 to rotate in the opposite direction around the connecting shaft, causing the second connecting seat 16 to move in the opposite direction, and at the same time driving the limiting mechanism 9 to withdraw from between the wheels of the vehicle to be blocked and return to the initial position.

[0041] The first linkage component 6 of this application includes two parallel first links 13 and a second link 14, and the second linkage component 7 includes two parallel third links 15. The two linkage components form their respective parallelogram structures (i.e., double four-link structures) with the first connecting seat 12 and the second connecting seat 16. The two parallelogram structures are synchronously driven by a set of sector gears, so that the two sets of four links can overlap when retracted. That is, in the non-working state, the footprint is relatively small, which is conducive to the flexible operation of the transport tanker and the utilization of site space.

[0042] Furthermore, the limiting mechanism 9 also includes a limiting seat 18 and a third driving device 19. The third driving device 19 is fixedly connected to the second connecting seat 16, and the limiting seat 18 is drive-connected to the third driving device 19.

[0043] It should be noted that, as Figure 3 As shown, the limiting seat 18 and the third driving device 19 are fixedly connected. The third driving device 19 is used to drive the limiting seat 18 to move in the vertical direction. For example, the third driving device 19 can be a cylinder. The limiting seat 18 is fixedly connected to the output end of the cylinder. When the limiting mechanism 9 is located between the wheels of the vehicle to be blocked, the third driving device 19 drives the limiting seat 18 to descend and press against the ground to limit the wheels. When the blocking process ends, the third driving device 19 drives the limiting seat 18 to rise, and finally removes the limiting mechanism 9 from between the wheels of the vehicle to be blocked and returns it to its initial state.

[0044] Furthermore, the limiting seat 18 is provided with wedge-shaped contact surfaces on both sides along the first direction, which are adapted to the outer contour of the wheel of the vehicle to be blocked.

[0045] It should be noted that the length direction of the limiting seat 18 is consistent with the first direction, and the limiting seat 18 is also provided with wedge-shaped abutment surfaces on both sides, so that when the tanker truck slips after the limiting seat 18 is inserted into the gap between the wheels of the vehicle to be blocked, it can abut against the inner side of the wheel to limit the displacement of the vehicle.

[0046] Furthermore, the mounting component 3 is also equipped with a detection device 20, which is used to locate the blocking position of the wheel of the vehicle to be blocked.

[0047] It should be noted that the detection device 20 can locate the position of the wheel to be blocked. For example, the detection device 20 can be a laser rangefinder sensor, which is installed on the first connecting seat 12. The laser rangefinder sensor can measure the wheel position data and feed the data back to the system. The system controls the limiting mechanism 9 to move along the first direction according to the measurement result so as to move the wheel blocker to the appropriate position. When it is necessary to position the wheels of the vehicle to be blocked, the detection device 20 emits a laser beam that illuminates the wheels. At this time, the limiting mechanism 9 does not correspond to the gap between the wheels. However, by receiving the reflected laser signal, the distance that the limiting mechanism 9 needs to move towards the gap between the wheels can be detected (i.e., the travel distance required for the limiting mechanism 9 to move towards the gap between the wheels along the second direction). However, since the limiting mechanism 9 does not correspond to the gap between the wheels, it needs to move along the first direction to the position corresponding to the gap between the wheels. During the movement of the limiting mechanism 9 along the first direction, when the laser emitted by the detection device 20 passes between the wheels, the distance detected by the detection device 20 is much greater than the distance that the limiting mechanism 9 needs to move towards the gap between the wheels. Therefore, it can be determined that the limiting mechanism 9 has moved to the position corresponding to the gap between the two wheels, and the first drive device 2 stops working at this time.

[0048] Working principle: First, the initial positioning is completed by the bearing mechanism 1: The laser range sensor 20 on the mounting component 3 first locates the position of the wheel to be blocked and detects the distance that the limiting mechanism 9 needs to move into the gap between the wheels to be blocked. At this time, the first drive device 2 is started, driving the mounting component 3 to slide along the first direction, driving the support 11, the first connecting seat 12 and the entire drive adjustment mechanism 4 and the limiting mechanism 9 fixed on the mounting component 3 to move synchronously. When the distance detected by the detection device 20 is much greater than the distance that the limiting mechanism 9 needs to move into the gap between the wheels to be blocked, it can be determined that the mounting component 3 has moved to the position corresponding to the gap between the two wheels to be blocked. The drive device 2 stops working, so that the whole device moves to the position corresponding to the wheel to be blocked. Subsequently, the drive adjustment mechanism 4 transmits power through a double parallelogram linkage structure and gear transmission: the drive end of the second drive device 5 extends, pushing the first link 13 near the limiting mechanism 9 to rotate around the hinge point with the first connecting seat 12 toward the wheel to be blocked; because the first linkage component 6 is a parallelogram structure, the other first link 13 rotates synchronously in the same direction, driving the second link 14 to move toward the wheel to be blocked. At this time, the sector gear 17 connected to the connecting shaft key near the limiting mechanism 9 also rotates synchronously, driving the sector gear 17 connected to the connecting shaft key away from the limiting mechanism 9 to rotate in the opposite direction through meshing transmission, driving the two third links 15 to rotate around the connecting axis toward the wheel to be blocked; the second linkage component 7 is also a parallelogram structure, which will push the second connecting seat 16 to move toward the gap between the wheels to be blocked, and finally drive the limiting mechanism 9 to move between the wheels to be blocked. When the limiting mechanism 9 reaches the wheel gap, the third drive device 19 drives the limiting seat 18 to descend and press against the ground, forming a limiting block for the wheel. After the vehicle blocking process is completed, the third drive device 19 drives the limit seat 18 to rise, and the second drive device 5 drives the first linkage assembly 6 to move away from the wheel to be blocked. The sector gear 17, which is connected to the connecting shaft key near the limit mechanism 9, will rotate in the opposite direction synchronously with the first connecting rod 13. Through the meshing relationship, it drives the sector gear 17, which is connected to the connecting shaft key away from the limit mechanism 9, to rotate in the forward direction. This drives the two third connecting rods 15 to rotate in the opposite direction around the connecting shaft, causing the second connecting seat 16 to move towards the bearing mechanism 1. At the same time, it drives the limit mechanism 9 to withdraw from between the wheels to be blocked and return to its initial position, completing the entire vehicle blocking process cycle. This device is easy to operate. By reducing the number of drive devices, the manufacturing cost and maintenance difficulty of the equipment are reduced. In addition, by reducing the number of drive devices, the error influence that may be caused by the multi-drive coordinated operation is eliminated, improving the reliability of the vehicle blocking action.
