Description

Technical Field

[0001] This utility model belongs to the field of traction transportation technology, and in particular relates to a traction transportation device. Background Technology

[0002] In today's society, with the rapid development of the logistics and transportation industry, traction transport devices play an increasingly important role in freight transportation. A traction transport device is a type of equipment used to tow or transport goods, and it comes in various types and application scenarios. However, existing traction transport devices still face some problems and challenges, requiring further improvement and refinement.

[0003] In traditional tractor-trailer systems, the vehicle's traction and braking systems are typically implemented using mechanical or hydraulic systems. These systems can suffer from slow response, low precision, and high energy consumption in certain situations, impacting the vehicle's transport efficiency and safety. Furthermore, traditional tractor-trailer systems also suffer from high maintenance costs, high failure rates, and excessive noise, requiring further improvement.

[0004] With the continuous advancement of technology, electrification and intelligent technologies are gradually being applied to tractor-trailer systems. For example, new energy vehicles such as electric vehicles and fuel cell vehicles are gradually replacing traditional fuel vehicles, making tractor-trailer systems more environmentally friendly and energy-efficient.

[0005] Furthermore, with the increasing demand for cargo transportation, traction transport vehicles also need to adapt to more complex and diverse application scenarios. Based on the requirements for transporting the main beam of wind turbine blades, the main beam length can reach 100m. The main beam is supported by a tooling of similar length, which is supported by casters. Previous transportation methods involved multiple people manually pushing the tooling for transfer. The disadvantages are that it requires many people (10 people), resulting in high labor costs, slow transfer speed, and high workload for personnel. Alternatively, a transport vehicle can be used for transfer, but this still requires manual control of the vehicle. This method has low operational efficiency, and inaccurate manual operation can easily cause the transport vehicle to pull on the tooling, resulting in damage to the tooling or workpiece, and low transportation efficiency. This method also requires manual attachment, making it inconvenient for the transport vehicle to enter and exit. Utility Model Content

[0006] In order to overcome the shortcomings of existing technologies, the purpose of this utility model is to propose a traction and transportation device, which is convenient and easy to use and has strong traction capacity.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a traction transport device, comprising at least one traction rod disposed below the traction object, and at least one traction unit corresponding to the traction rod, wherein the traction unit comprises:

[0008] The mobile platform serves as the main moving body for traction and transportation;

[0009] The attachment device is installed in the mobile platform. The attachment device surrounds the towing rod, and the mobile platform transmits the traction force to the towing rod through the attachment device, thereby realizing the traction of the object being towed.

[0010] A vision sensor is mounted on the mobile platform or attachment device, and the tow bar has a directional pattern for orientation recognition, which the vision sensor is used to recognize.

[0011] Furthermore, the mobile platform is provided with a groove to facilitate the traction rod entering the attachment device from the side;

[0012] The hook-on device has an openable and closable locking device on one side corresponding to the groove.

[0013] Furthermore, there is a gap between the hook-up device and the traction rod.

[0014] Furthermore, the mobile platform is an integral differential wheel system.

[0015] Furthermore, the overall differential wheel system includes four drive wheels.

[0016] The beneficial effects of adopting this technical solution are:

[0017] This utility model features an openable and closable hook-up device, facilitating the entry and exit of transport vehicles; it also facilitates the transfer of transport vehicles between tow bars, and the transfer from one towed object to another.

[0018] This invention features a vision sensor that can monitor the relative position of the transport unit and the towed object in real time, so as to adjust the angle of the towing unit and make the movement posture controllable.

[0019] The traction and transportation unit proposed in this utility model is convenient and easy to use, has strong traction capacity, and the transportation vehicle has a simple structure and low cost, resulting in significant economic benefits.

[0020] This utility model features an adjustable connection to the towed object via an openable and closable hook-up device. By using a visual sensor to identify the angle and adjust the towing unit's state, it achieves the following benefits: Improved transport stability: The angle-adjustable towing vehicle can adjust the traction angle according to road conditions and transport needs during transport, enhancing stability and safety. Reduced wear and impact: Adjusting the traction angle reduces impact and friction between the towing and towed vehicles, decreasing wear and extending service life. Flexible handling of different road conditions: The angle-adjustable towing vehicle can adjust the traction angle according to different road conditions and transport needs, achieving more flexible and reliable transport. Improved transport efficiency: By rationally adjusting the traction angle, the balance between traction force and resistance is optimized, improving transport efficiency. In summary, the towing vehicle offers beneficial effects such as improved transport stability, reduced wear and impact, flexible handling of different road conditions, and increased transport efficiency.

[0031] To make the purpose, technical solution and advantages of this utility model clearer, the present utility model will be further described below with reference to the accompanying drawings.

[0032] In this embodiment, see Figure 1 As shown, this utility model proposes a traction and transportation device, in which at least one traction rod 2 is provided below the object being traction 1, and at least one traction unit 3 is provided corresponding to the traction rod 2. The traction unit 3 includes:

[0033] Mobile platform 31 is the main moving body for traction and transportation;

[0034] The attachment device 32 is installed in the mobile platform 31. The attachment device 32 surrounds the traction rod 2. The mobile platform 31 transmits the traction force to the traction rod 2 through the attachment device 32, thereby realizing the traction of the object 1 being pulled.

[0035] A vision sensor 33 is mounted on the mobile platform 31 or the mounting device 32. The traction rod 2 has a direction pattern 34 for direction recognition. The vision sensor 33 obtains the relative angle relationship between the traction unit 3 and the traction object 1 by recognizing the direction pattern 34, thereby adjusting the working state of the traction unit 3. Figure 6 , Figure 8 As shown.

[0036] Preferably, the vision sensor 33 is positioned below the mounting device 32 and mounted upwards, and the lower part of the traction rod 2 has a directional pattern 34 for direction recognition, which the vision sensor 33 is used to recognize.

[0037] As an optimization of the above embodiment, the mobile platform 31 is provided with a groove 35 to facilitate the traction rod 2 to enter the hook-up device 32 from the side;

[0038] The hook-on device 32 has an openable and closable locking device on one side corresponding to the groove 35;

[0039] like Figure 2 As shown, when the locking device is in the open state, the operating moving platform 31 actively moves closer to the traction rod 2, causing the traction rod 2 to pass through the groove 35 on the moving platform 31 and enter the hook-up device 32 through the open locking device. Then, the locking device is locked, and the traction rod 2 is confined inside the hook-up device 32. Figure 3 As shown.

[0040] Preferably, there is a gap between the hook-up device 32 and the traction rod 2, which can adapt to the changes in the height and angle of the traction rod 2 relative to the transport unit during the traction process within a certain range, so that the transport unit can carry out effective traction operations on irregular uneven ground.

[0041] As an optimized solution of the above embodiment, the mobile platform 31 is an integral differential wheel system 36, which can realize forward and reverse movement, turning, and stationary rotation by adjusting the speed of the left and right wheels.

[0042] Preferably, the integral differential wheel system 36 includes four powered wheels, which can maximize the conversion of the transport unit's own weight into the generated traction force.

[0043] This invention employs a fully active wheel system 36, which maximizes the conversion of the transport unit's own weight into the generated traction force. Under the same weight, the transport vehicle can tow a heavier load 1. The same load 1 can be towed using a lighter transport unit, resulting in a more compact size. This leads to more efficient and energy-saving operations.

[0044] To better understand this utility model, the working principle of this utility model will be described in detail below:

[0045] When the traction unit 3 travels to the vicinity of the tow bar 2 of the towed object 1, the locking device of the coupling device 32 is in the open state, such as... Figure 4 As shown;

[0046] The traction unit 3 travels to a position beneath the towed object 1, causing the tow rod 2 to pass through the groove 35 on the moving platform 31 and enter the coupling device 32. The locking device then locks the tow rod 2, confining it within the coupling device 32. Figure 5 As shown;

[0047] The vision sensor 33 obtains the relative angular relationship between the traction unit 3 and the traction object 1 by recognizing the orientation pattern 34, and completes the state adjustment of the traction unit 3, such as... Figures 6-8 As shown;

[0048] The traction unit 3 moves to complete the traction task.

[0049] During use, two or more traction units 3 can be used together for traction, such as Figure 9 As shown.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
