Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical logistics vehicle technology, specifically an extendable unmanned logistics vehicle. Background Technology

[0002] Hazardous chemicals are short for dangerous chemicals, which refer to chemicals that have dangerous characteristics such as explosion, flammability, toxicity, infectiousness, corrosiveness, and radioactivity. They are chemicals that can easily cause personal injury, property damage, or environmental pollution during transportation, storage, production, operation, use, and disposal, and therefore require special protection.

[0003] The core components of a hazardous chemical logistics vehicle include a dedicated tank / cargo box, safety accessories, a monitoring system, fire-fighting equipment, and warning signs. Before use, check the sealing of the components and the qualification documents. Connect the anti-static grounding clamp before loading and unloading. When driving within the factory area, comply with speed limits, avoid densely populated areas, and avoid sudden starts and stops. Check the tank status every 2 hours during the journey. After arriving at the designated area, unload according to the factory's procedures, empty any residue, clean the vehicle, and keep accurate transportation records. The entire process must comply with the factory's hazardous chemical transportation management regulations.

[0004] If ordinary hazardous chemical transport equipment lacks effective securing of storage tanks, the tanks are highly susceptible to displacement or even falling during transport, especially during bumps or sudden braking. In such cases, the hazardous chemicals inside the tanks will leak, polluting the surrounding environment and posing a serious threat to road safety and human health. More importantly, for storage tanks of different sizes, it is necessary to frequently replace the corresponding fixing devices. The operation requires first disassembling the old device, measuring the storage tank parameters, and then installing new clamps, brackets, and other accessories. This process is cumbersome and time-consuming, severely impacting transport efficiency. Furthermore, improper use of tools or inaccurate control of fixing force during replacement may scratch the outer wall of the storage tank or damage the fixing device, further increasing the safety hazards of subsequent transport, creating a double problem of "low efficiency and high risk." Utility Model Content

[0005] The purpose of this utility model is to provide an extendable unmanned logistics vehicle to solve the problems of ordinary hazardous chemical transport devices, which, due to the lack of fixing of storage tanks, are prone to falling off during use, causing the hazardous chemicals inside to spill out, which is quite dangerous. The process of replacing different sizes of fixing devices with different sizes of storage tanks is cumbersome and poses a risk of damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An extendable unmanned logistics vehicle includes a base plate, with two base plates arranged parallel to each other:

The support unit is used to support a hazardous chemical storage device placed on the fixing plate.

[0009] The fixing unit includes a bracket fixedly mounted on the fixing plate, a threaded rod rotatably mounted on the bracket, a sliding plate threadedly connected to the threaded rod, a vertical plate fixedly mounted on the sliding plate, and a bearing plate fixedly mounted on the vertical plate. The fixing unit is used to clamp and fix the hazardous chemical storage device.

[0010] Preferably, the base plate is rotatably provided with a plurality of parallel wheels, and each wheel is evenly distributed at the corner of the base plate.

[0011] Preferably, an adjusting plate is fixedly provided on the output end of the hydraulic cylinder, the adjusting plate is movably connected to the shaft, a chuck is fixedly provided on the shaft, and two chucks are distributed on both sides of the connecting plate.

[0012] Preferably, a positioning ring is fixedly provided on the bearing plate, and multiple parallel control plates are fixedly provided on the positioning ring. A control plate is rotatably provided on the control plate, and a pressing plate is movably provided on the control plate.

[0013] Preferably, the distance between two adjacent pressing plates is equal, and the clamping surface of the pressing plates is roughened.

[0014] Preferably, a servo motor is fixedly mounted on the bracket, and the output end of the servo motor is fixedly connected to the threaded rod.

[0015] Preferably, the threaded rod has two threads, and the two threads rotate in opposite directions. A guide rod is fixedly mounted on the bracket, and the guide rod and the threaded rod are arranged parallel to each other.

[0016] Preferably, the two slide plates are evenly distributed at both ends of the threaded rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention utilizes wheels mounted on a base plate to enable the control device to move forward. Furthermore, a threaded rod mounted on a bracket and a sliding plate threaded onto the rod allow workers to secure the hazardous chemical storage device. A servo motor controls the distance between the two sliding plates, ensuring the pressing plate on the support plate stably clamps the outer surface of the storage device. This stable clamping and securing is achieved by adjusting the distance between the two sliding plates when dealing with storage tanks of different sizes. The simple and convenient design, along with the mechanical claw-like pressing plate, ensures a tight fit against the surface of the circular storage tank, resulting in a more secure clamping and improved safety during hazardous chemical transportation.

The fixing unit is used to clamp and fix the hazardous chemical storage device.

[0029] Reference Figures 1-3 Multiple parallel wheels 11 are rotatably mounted on the base plate 1, and each wheel 11 is evenly distributed at the corner of the base plate 1. The wheels 11 mounted on the base plate 1 enable the device body to move, thereby realizing the transportation of hazardous chemicals.

[0030] Reference Figures 2-4 An adjusting plate 121 is fixedly installed on the output end of the hydraulic cylinder 12. The adjusting plate 121 is movably connected to the shaft 13. A chuck 131 is fixedly installed on the shaft 13. Two chucks 131 are distributed on both sides of the connecting plate 22. The adjusting plate 121 installed on the output end of the hydraulic cylinder 12 enables the operator to control the movement of the shaft 13 by adjusting the adjusting plate 121 when controlling the extension and retraction of the hydraulic cylinder 12. The moving shaft 13 can control the included angle between the connecting plates 22, thereby controlling the vertical height of the fixed plate 4, which is convenient for the operator to fix hazardous chemicals.

[0031] Reference Figures 1-4 A positioning ring 71 is fixedly installed on the support plate 7. Multiple parallel control plates 72 are fixedly installed on the positioning ring 71. A control plate 73 is rotatably installed on the control plate 72. A pressing plate 74 is movably installed on the control plate 73. The positioning ring 71 on the support plate 7 limits and fixes the control plate 72 and the control plate 73, thereby facilitating the clamping of storage tanks of different sizes.

[0032] Reference Figures 2-4The distance between two adjacent pressing plates 74 is equal, and the clamping surface of the pressing plate 74 is rough. By setting the positional relationship between each pressing plate 74, the stability and safety of fixing the hazardous chemical storage tank are ensured.

[0033] Reference Figures 1-4 A servo motor 43 is fixedly mounted on the bracket 41. The output end of the servo motor 43 is fixedly connected to the threaded rod 42. The servo motor 43 mounted on the bracket 41 controls the threaded rod 42.

[0034] Reference Figures 1-3 The threaded rod 42 has two threads with opposite rotation directions. A guide rod 44 is fixedly mounted on the bracket 41 and is parallel to the threaded rod 42. Two sliding plates 5 are evenly distributed at both ends of the threaded rod 42. The two threads with opposite rotation directions on the threaded rod 42 enable the sliding plates 5 connected to both ends of the threaded rod 42 to move simultaneously when the threaded rod 42 rotates, thus clamping and fixing the storage tank.

[0035] Specifically, the solution involves: wheels 11 mounted on the base plate 1 to enable the control device to move forward; and a threaded rod 42 mounted on the bracket 41 and a sliding plate 5 threadedly connected to the threaded rod 42, allowing workers to secure the hazardous chemical storage device. First, a servo motor 43 controls the distance between the two sliding plates 5, ensuring that the pressing plate 74 on the bearing plate 7 can stably clamp the outer surface of the storage device. The two threads on the threaded rod 42, rotating in opposite directions, allow the sliding plates 5 threadedly connected to both ends to move simultaneously as the threaded rod 42 rotates, thus securing the storage tank. This method can be applied to storage tanks of different sizes by adjusting the distance between the two sliding plates 5, making it simple and convenient. Simultaneously, the mechanical claw-like pressing plate 74 can tightly adhere to the surface of the circular storage tank, making the clamping more stable and improving the safety of hazardous chemical transportation.
