Description

Technical Field

[0001] This utility model belongs to the field of trailer auxiliary movement, specifically a trailer front support auxiliary movement device. Background Technology

[0002] A trailer is a vehicle without a power drive and that needs to be towed by a tractor (such as a truck or tractor unit) to move. It is usually used for cargo transportation or special operations. It is an important type of equipment in logistics transportation and engineering operations. Through modular design, it can achieve efficient and flexible cargo carrying and transfer.

[0003] During the manufacturing process of trailers, frequent adjustments to trailer positions are required to adapt to different workstations. However, the number of tractor units is limited and the allocation cost is high. As a result, companies often rely on manual labor to push trailers for short-distance movement. However, trailers typically weigh several tons, and manual pushing is not only labor-intensive and inefficient, but also prone to insufficient movement precision due to operator fatigue, thus restricting the overall production cycle.

[0004] Therefore, this utility model provides a trailer front support auxiliary moving device. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems mentioned in the background art regarding the limited number of tractor vehicles and high allocation costs in the production and manufacturing process of trailers, a trailer front support auxiliary moving device is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A trailer front support auxiliary moving device of this utility model includes a load-bearing body. A hydraulic jack is mounted on the top of the load-bearing body. A connecting shaft is fixedly connected to the output end of the hydraulic jack. A support platform is slidably fitted in the middle of the side wall of the connecting shaft. The support platform is sleeved on the outside of the connecting shaft. A trailer traction mechanism is connected to the middle of the side wall of the support platform. A trailer body is connected to the middle of the inner side wall of the trailer traction mechanism. A lifting assembly is provided at the bottom of the load-bearing body. Multiple movable wheels are installed at the bottom of the lifting assembly. A steering motor is mounted at the bottom of the load-bearing body. A travel motor is mounted at the bottom of the inner side wall of the load-bearing body. A motor controller is mounted at the bottom of the inner side wall of the load-bearing body. The motor controller adopts a dual-drive form. The steering motor and the motor controller are connected through a communication interface. The movable wheels and the steering motor are connected through a motor drive interface. The motor and motor controller are connected via a communication interface, and the movable wheels and travel motor are connected via a motor drive interface. A battery is installed at the bottom of the inner wall of the load-bearing body, and a remote control is slidably installed in the middle of the side wall of the load-bearing body. Traditional trailers require a tractor to move. By setting up movable wheels, a steering motor, a travel motor, a motor controller, a battery, and a remote control, the trailer can be powered even without a tractor. This allows the trailer to move short distances remotely after being detached from the tractor, without repeatedly connecting to the tractor to adjust its position, saving a lot of time and manpower, significantly improving work efficiency. Short-distance movement does not require starting the tractor, saving fuel and engine wear. Long-term use significantly reduces operating costs. At the same time, the trailer can be moved independently to the maintenance area for easy inspection, replacement of parts, or cleaning, shortening downtime and reducing efficiency loss due to equipment idleness.

[0007] Preferably, the lifting assembly includes multiple connecting rods, which are symmetrically fixed to the bottom of the load-bearing body. A movable shaft is slidably connected to the middle of the inner sidewall of each connecting rod. The movable shaft is connected to a movable wheel. A first connecting plate is fixed between adjacent movable shafts. A first gear is rotatably connected to the middle of the sidewall of the first connecting plate. A fixed shaft is fixed between a pair of first gears. A control handle is fixed to the middle of the sidewall of one of the first gears. A second gear is meshed with the first gear. A telescopic rod is fixed to the top of the second gear. A second connecting plate is fixed between the telescopic rod and the connecting rod. When encountering speed bumps, thresholds, or small obstacles, the lifting assembly can adjust the distance between the load-bearing body and the movable wheel, increasing the chassis height of the load-bearing body, reducing scratches between the load-bearing body and obstacles, and allowing the trailer to pass smoothly. Simultaneously, by fine-tuning the height of the load-bearing body, the front support auxiliary moving device can be aligned with trailers of different heights, adapting to different vehicle models, improving the device's flexibility, and meeting diverse transportation needs.

[0008] Preferably, a heat sink is installed in the middle of the side wall of the load-bearing body, and a bearing motor is assembled in the middle of the inner side wall of the heat sink. Multiple heat dissipation blades are fixed to the output end of the bearing motor. The heat sink is connected to the load-bearing body. The steering motor, travel motor, motor controller and battery assembled inside the load-bearing body are prone to generating a lot of heat under long-term operation or high-load conditions. If the heat cannot be dissipated in time, it will lead to a decline in the performance of electronic components or even cause equipment shutdown or failure. This step, by setting up the heat sink, bearing motor and heat dissipation blades, can force airflow, quickly dissipate heat, make the components work within a safe temperature range, improve equipment reliability and reduce the risk of thermal failure.

[0009] Preferably, a polytetrafluoroethylene (PTFE) bushing is installed in the middle of the side wall of the connecting shaft, and multiple rollers are rotatably connected in the middle of the inner side wall of the support platform. The rollers are located between the connecting shaft and the support platform. The coefficient of friction of PTFE is much lower than that of metal-to-metal direct contact. By setting the PTFE bushing, the frictional resistance between moving parts can be significantly reduced, and energy loss can be reduced. At the same time, the rollers transmit force through rolling motion, and their coefficient of friction is much lower than that of sliding friction. By setting multiple rollers, the energy loss between the connecting shaft and the support platform can be further reduced, heat generation and wear can be reduced, and the service life of the components can be extended.

[0010] Preferably, the top of the support platform is provided with multiple liquid inlet holes, which are located above the roller. This step, by providing multiple liquid inlet holes on the top of the support platform, can transform the direct contact between metals into liquid friction, reduce the coefficient of friction, and reduce surface scratches, seizing, or overheating caused by dry friction.

[0011] Preferably, the load-bearing body is made of Q335B carbon steel, and the support platform is made of Q355B carbon steel. This step, by using a load-bearing body and a support platform made of Q335B carbon steel, can not only improve the structural strength and load-bearing capacity of the device, but also enhance the environmental adaptability of the device and extend its service life.

[0012] Preferably, the movable wheels are made of solid nylon. This step eliminates internal air gaps by using solid nylon movable wheels, allowing them to easily handle the handling of goods weighing several tons, and they are not easily deformed after long-term use.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The trailer front support auxiliary moving device described in this utility model addresses the issue that traditional trailers require traction from a tractor unit to move. By incorporating movable wheels, a steering motor, a travel motor, a motor controller, a battery, and a remote control, the device provides a power source for the trailer even without a tractor unit. This allows the trailer to move short distances remotely after detaching from the tractor unit, eliminating the need for repeated tractor unit connections to adjust the trailer's position. This saves significant time and manpower, greatly improving operational efficiency. Furthermore, short-distance movement does not require starting the tractor unit, saving fuel and engine wear. Long-term use significantly reduces operating costs. Additionally, the trailer can be moved independently to a maintenance area for easy inspection, parts replacement, or cleaning, minimizing downtime and reducing efficiency losses due to equipment idleness.

[0015] 2. The trailer front support auxiliary moving device described in this utility model can adjust the distance between the load-bearing body and the movable wheel by setting up a lifting component when encountering speed bumps, thresholds, or small obstacles. This can raise the chassis height of the load-bearing body, reduce the scraping between the load-bearing body and obstacles, and allow the trailer body to pass smoothly. At the same time, by finely adjusting the height of the load-bearing body, the front support auxiliary moving device can be aligned with trailer bodies of different heights, adapt to different vehicle models, improve the flexibility of the device, and meet diverse transportation needs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 5As shown, an embodiment of the present invention provides a trailer front support auxiliary moving device, comprising a load-bearing body 1, a hydraulic jack 11 mounted on the top of the load-bearing body 1, a connecting shaft 12 fixedly connected to the output end of the hydraulic jack 11, a support platform 13 slidably fitted on the middle of the side wall of the connecting shaft 12, the support platform 13 fitting around the outside of the connecting shaft 12, a trailer traction mechanism 14 connected to the middle of the side wall of the support platform 13, a trailer body 15 connected to the middle of the inner side wall of the trailer traction mechanism 14, a lifting assembly provided at the bottom of the load-bearing body 1, multiple movable wheels 16 installed at the bottom of the lifting assembly, a steering motor 17 mounted at the bottom of the load-bearing body 1, a travel motor 18 mounted at the bottom of the inner side wall of the load-bearing body 1, and a travel motor 18 mounted at the bottom of the inner side wall of the load-bearing body 1. Equipped with a motor controller 19, the motor controller 19 adopts a dual-drive configuration. The steering motor 17 and the motor controller 19 are connected via a communication interface. The movable wheel 16 and the steering motor 17 are connected via a motor drive interface. The travel motor 18 and the motor controller 19 are connected via a communication interface. The movable wheel 16 and the travel motor 18 are connected via a motor drive interface. A battery 110 is installed at the bottom of the inner wall of the load-bearing body 1. A remote control 111 is slidably installed in the middle of the side wall of the load-bearing body 1. The operator fits the support platform 13 connecting the trailer traction mechanism 14 and the trailer body 15 onto the outside of the connecting shaft 12, then removes the remote control 111 from the load-bearing body 1 and presses the corresponding switch button. When the storage battery 110 supplies power to the motor controller 19, the motor controller 19 transmits movement signals to the steering motor 17 and the travel motor 18 via a communication interface. When the travel motor 18 receives the forward signal, it controls multiple movable wheels 16 to move forward, at which point the load-bearing body 1 drags the trailer body 15 forward. When the steering motor 17 receives the steering signal, it controls multiple movable wheels 16 to turn, at which point the load-bearing body 1 drives the trailer body 15 to change direction. Before moving, the operator observes the terrain and activates the lifting assembly to adjust the height of the load-bearing body 1 above the ground. Traditionally, the trailer body 15 requires a tractor unit to move. By incorporating movable wheels 16, steering motor 17, travel motor 18, motor controller 19, battery 110, and remote controller 111, the trailer body 15 can be powered even without a tractor unit. This allows the trailer body 15 to move short distances remotely after detaching from the tractor unit, eliminating the need for repeated connection to the tractor unit to adjust its position. This saves significant time and manpower, greatly improving operational efficiency. Furthermore, short-distance movement does not require starting the tractor unit, saving fuel and engine wear. Long-term use significantly reduces operating costs. Additionally, the trailer can be moved independently to a maintenance area for easy inspection, replacement of parts, or cleaning, shortening downtime and reducing efficiency losses due to equipment idleness.

[0027] like Figures 1 to 4As shown, the lifting assembly includes multiple connecting rods 2, which are symmetrically fixed to the bottom of the load-bearing body 1. A movable shaft 21 is slidably connected to the middle of the inner wall of each connecting rod 2. The movable shaft 21 is connected to a movable wheel 16. A first connecting plate 22 is fixed between adjacent movable shafts 21. A first gear 23 is rotatably connected to the middle of the side wall of the first connecting plate 22. A fixed shaft 24 is fixed between a pair of first gears 23. A control handle 25 is fixed to the middle of the side wall of one first gear 23. A second gear 26 meshes with the first gear 23. A telescopic rod 27 is fixed to the top of the second gear 26. A second connecting plate 28 is fixed between the telescopic rod 27 and the connecting rod 2. When the operator observes the terrain and rotates the control handle 25, the control handle 25 will drive the first gear 23 and the fixed shaft 24 to rotate synchronously. When the first gear 23 rotates, it will drive the gears meshing with it... The second gear 26 rotates, adjusting the extension and retraction of the telescopic rod 27. When the telescopic rod 27 extends or retracts, it drives the second connecting plates 28 on both sides to move up and down. When the second connecting plates 28 move, they drive the connecting rod 2 to move. At this time, the movable shaft 21 slides inside the connecting rod 2, thereby adjusting the distance between the load-bearing body 1 and the movable wheel 16. When encountering speed bumps, thresholds, or small obstacles, the lifting component is set to adjust the distance between the load-bearing body 1 and the movable wheel 16, which can raise the chassis height of the load-bearing body 1, reduce the scraping between the load-bearing body 1 and the obstacles, and allow the trailer body 15 to pass smoothly. At the same time, by finely adjusting the height of the load-bearing body 1, the front support auxiliary moving device can be aligned with trailer bodies 15 of different heights, adapting to different vehicle models, improving the flexibility of the device, and meeting diverse transportation needs.

[0028] like Figure 2 and Figure 3 As shown, a heat sink 3 is installed in the middle of the side wall of the load-bearing body 1. A bearing motor 31 is assembled in the middle of the inner side wall of the heat sink 3. Multiple heat dissipation blades 32 are fixed to the output end of the bearing motor 31. The heat sink 3 is connected to the load-bearing body 1. When the load-bearing body 1 gets hot due to long-term operation, the operator starts the bearing motor 31. The bearing motor 31 will drive the multiple heat dissipation blades 32 to rotate. Because the heat sink 3 is connected to the load-bearing body 1, when the heat dissipation blades 32 rotate, they will transfer the heat inside the load-bearing body 1 to the outside of the load-bearing body 1. The steering motor 17, travel motor 18, motor controller 19 and battery 110 assembled inside the load-bearing body 1 are prone to generating a lot of heat under long-term operation or high-load conditions. If the heat cannot be dissipated in time, it will lead to the deterioration of the performance of electronic components or even cause equipment shutdown or failure. This step, by setting up the heat sink 3, bearing motor 31 and heat dissipation blades 32, can force airflow, quickly dissipate heat, make the components work within a safe temperature range, improve equipment reliability and reduce the risk of thermal failure.

[0029] like Figure 2 and Figure 5As shown, a polytetrafluoroethylene (PTFE) bushing 4 is installed in the middle of the side wall of the connecting shaft 12, and multiple rollers 41 are rotatably connected in the middle of the inner side wall of the support platform 13. The rollers 41 are located between the connecting shaft 12 and the support platform 13. After the operator fits the support platform 13 onto the outside of the connecting shaft 12, the load-bearing body 1 begins to drag the trailer body 15 to move. At this time, the connecting shaft 12 and the support platform 13 will continuously rub against each other during the movement. The multiple rollers 41 rotating inside the support platform 13 will contact the connecting shaft 12 and rotate between the connecting shaft 12 and the support platform 13. The coefficient of friction of PTFE is much lower than that of metal-to-metal direct contact. By setting the PTFE bushing 4, the frictional resistance between moving parts can be significantly reduced, and energy loss can be reduced. At the same time, the rollers 41 transmit force through rolling motion, and their coefficient of friction is much lower than that of sliding friction. By setting multiple rollers 41, the energy loss between the connecting shaft 12 and the support platform 13 can be further reduced, heat generation and wear can be reduced, and the service life of the components can be extended.

[0030] like Figure 5 As shown, the support platform 13 has multiple liquid inlet holes 5 on its top. The liquid inlet holes 5 are located above the roller 41. Operators will periodically add lubricating oil between the connecting shaft 12 and the support platform 13 through the multiple liquid inlet holes 5 to maintain the connecting shaft 12 and the support platform 13. This step, by having multiple liquid inlet holes 5 on the top of the support platform 13, can convert the direct contact between metal and metal into liquid friction, reduce the coefficient of friction, and reduce surface scratches, seizing, or overheating caused by dry friction.

[0031] like Figures 1 to 5 As shown, the load-bearing body 1 is made of carbon steel Q335B, and the support platform 13 is made of carbon steel Q355B. This step, by using the load-bearing body 1 and the support platform 13 made of carbon steel Q335B, can not only improve the structural strength and load-bearing capacity of the device, but also enhance the environmental adaptability of the device and extend its service life.

[0032] like Figures 1 to 4 As shown, the movable wheel 16 is made of solid nylon. This step eliminates internal air gaps by using solid nylon movable wheels 16, allowing the movable wheel 16 to easily handle the handling of goods weighing several tons, and it is not easily deformed after long-term use.

[0033] Working principle: The operator attaches the support platform 13 connecting the trailer traction mechanism 14 and the trailer body 15 to the outside of the connecting shaft 12, then removes the remote control 111 from the load-bearing body 1 and presses the corresponding switch button. At this time, the battery 110 supplies power to the motor controller 19, which transmits movement signals to the steering motor 17 and the travel motor 18 through the communication interface. When the travel motor 18 receives the forward signal, it controls multiple movable wheels 16 to move forward, thus dragging the trailer body 1. 15. Moving forward, when the steering motor 17 receives a steering signal, it controls multiple movable wheels 16 to turn. At this time, the load-bearing body 1 will drive the trailer body 15 to change direction. Before moving, the operator observes the terrain and activates the lifting assembly to adjust the height of the load-bearing body 1 from the ground. The operator observes the terrain and turns the control handle 25. The control handle 25 will drive the first gear 23 and the fixed shaft 24 to rotate synchronously. When the first gear 23 rotates, it will drive the second gear 26, which meshes with it, to rotate. When the second gear 26 rotates, it will adjust the extension... The telescopic rod 27 extends and retracts, causing the second connecting plates 28 on both sides to move up and down. The movement of the second connecting plates 28 in turn moves the connecting rod 2. At this time, the movable shaft 21 slides inside the connecting rod 2, thereby adjusting the distance between the load-bearing body 1 and the movable wheel 16. When the load-bearing body 1 becomes hot due to prolonged operation, the operator starts the bearing motor 31. The bearing motor 31 drives multiple cooling blades 32 to rotate. Because the cooling cylinder 3 is connected to the load-bearing body 1, the rotation of the cooling blades 32 will dissipate heat from the load-bearing body. Heat inside the main body 1 is transferred to the outside of the load-bearing main body 1. After the operator fits the support platform 13 onto the outside of the connecting shaft 12, the load-bearing main body 1 begins to drag the trailer body 15. At this time, the connecting shaft 12 and the support platform 13 will rub against each other continuously during the movement. The multiple rotating rollers 41 inside the support platform 13 will contact the connecting shaft 12 and rotate between the connecting shaft 12 and the support platform 13. The operator will periodically add lubricating oil between the connecting shaft 12 and the support platform 13 through multiple liquid inlet holes 5 to maintain the connecting shaft 12 and the support platform 13.
