[0031] A transport vehicle is involved in the electrical inspection line of the automobile assembly workshop and other related automated assembly lines or logistics industries. The transport vehicle has functions such as high-speed travel, low-speed synchronization, automatic lifting of pallets, and synchronous power supply to production line equipment. In the electrical inspection line of the automobile assembly workshop, it can be used to transport electrical inspection equipment next to the automobile assembly line or to complete the on-the-go charging function before the car rolls off the line. Among them, the electrical inspection equipment is placed on the transport vehicle. When it is transported to the corresponding workstation of the worker, the worker needs to remove the electrical inspection equipment from the transport vehicle and then put it back on the transport vehicle after use. However, the transport vehicle is installed on the line body and needs to be powered synchronously with the production line equipment. It is generally at a high height, and it is not convenient for workers to directly remove the electrical inspection equipment from the transport vehicle.

[0032] The utility model provides a transport vehicle.

[0033] See also Figures 1 to 2 In one embodiment of the utility model, the transport vehicle 100 is used to be installed on the track of the electric inspection line body and move along the track; the transport vehicle 100 includes: a mounting frame 1, a moving component 2, a tray 3 and a driving component 4; the moving component 2 has at least a first connecting member 21 and a second connecting member 22, the second connecting member 22 has a movable stroke in the up and down directions relative to the first connecting member 21, and the first connecting member 21 is fixedly connected to the mounting frame 1; the tray 3 is fixedly connected to the second connecting member 22; the driving component 4 drives the tray 3 to move in the up and down directions.

[0034] In the technical solution of the present invention, the transport vehicle 100 includes: a mounting frame 1, a moving assembly 2, a tray 3, and a driving assembly 4. The mounting frame 1 is installed on the track of the electrical inspection line and moves along the track of the line; the tray 3 is used to place the electrical inspection equipment. Without considering manual operation, the tray 3 and the electrical inspection equipment are set at a higher position to facilitate power supply with other equipment on the production line. However, employees have different heights. Some employees cannot directly remove the electrical inspection equipment from the transport vehicle 100 and need to climb stairs to remove it. On the one hand, the setting of the stairs takes up the space of the employee's workstation, making it inconvenient for the employee to move and work. On the other hand, frequent climbing up and down the stairs increases the workload of the employee. Therefore, the solution of the present invention adopts a form in which the tray 3 can be raised and lowered. When it runs to the employee's workstation, the tray 3 is lowered to facilitate the employee to remove the electrical inspection equipment. After the employee has finished using it, the tray 3 is put back, and then the tray 3 is raised to continue moving along the track. Specifically, a moving assembly 2 is provided between the mounting frame 1 and the pallet 3. The moving assembly 2 includes at least two first connecting members 21 and second connecting members 22 that can move relative to each other in the up and down directions, wherein one of the first connecting member 21 and the second connecting member 22 is fixedly connected to the mounting frame 1, and the other is fixedly connected to the pallet 3, so that the pallet 3 can move in the up and down directions relative to the mounting frame 1. The driving assembly 4 drives the pallet 3 to move in the up and down directions. In addition, the moving assembly 2 does not necessarily include only the first connecting member 21 and the second connecting member 22, but may also include a third connecting member and more, depending on the movement formation of the pallet 3 and the size limit of the transport vehicle 100.

[0035] In one specific embodiment, the first connecting member 21 includes a first guide rail 211 extending in a vertical direction; the second connecting member 22 includes a second guide rail 221 extending in a vertical direction; the first guide rail 211 and the second guide rail 221 engage with each other and are relatively slidable in a first direction. The engagement of the first guide rail 211 and the second guide rail 221 prevents the first guide rail 211 and the second guide rail 221 from separating and derailing.

[0036] In order to increase the stability of the tray 3 during movement, in one embodiment, two second guide rails 221 are provided, which are fixedly arranged on both sides of the tray 3 in the left and right directions respectively, and two first guide rails 211 are also provided correspondingly, which are correspondingly installed on the mounting frame 1 and respectively cooperate with the two second guide rails 221.

[0037] The moving assembly 2 only enables the tray 3 to move in the up and down directions, and the driving assembly 4 is used to drive the tray 3 to move. The driving assembly 4 includes: a rotating member 41, a belt 42, and a first driving motor 43. The rotating member 41 is rotatably mounted on the mounting frame 1 and is located above the tray 3 in the up and down directions. One end of the belt 42 is fixedly connected to the tray 3, and the other end is fixedly connected to the rotating member 41. The first driving motor 43 is fixedly mounted on the mounting frame 1 and is connected to the rotating member 41 to drive the rotating member 41 to rotate, so that the belt 42 is wound around the rotating member 41, or the belt 42 is released from the rotating member 41. The first driving motor 43 rotates forward, so that the belt 42 is wound around the rotating member 41, thereby raising the tray 3. The first driving motor 43 rotates backward, so that the belt 42 is released from the rotating member 41, and the tray 3 descends under the action of gravity.

[0038] To prevent the drive assembly 4 from failing due to a break in the belt 42, the transport vehicle 100 further includes a first photoelectric sensor 5, which is fixed to the mounting frame 1 and positioned corresponding to the belt 42. When the belt 42 breaks, the first sensor cannot detect the belt 42 and thus issues a corresponding signal, prompting the user to replace the belt 42 in a timely manner.

[0039] In order to control the first drive motor 43 to rotate forward or reverse, the transport vehicle 100 further includes an operation controller 6, which is movably mounted on the mounting frame 1 and electrically connected to the first drive motor 43. When the transport vehicle 100 moves to an employee's workstation, the employee can control the motor to rotate forward or reverse by pressing a button on the operation controller 6.

[0040] To ensure that the pallet 3 can be raised and the transport vehicle 100 can be moved only after the employee has finished using the electrical inspection device and placed it back on the pallet 3, the transport vehicle 100 also includes a through-beam photoelectric sensor 7, which is provided on both sides of the pallet 3 in the left and right directions. The through-beam photoelectric sensor 7 is used to detect whether the electrical inspection device is present on the pallet 3. Only when the electrical inspection device is detected on the pallet 3 can the next operation be carried out.

[0041] In order to enable the transport vehicle 100 to move along the linear track, the transport vehicle 100 includes two pulley assemblies 8 and a second drive motor 9. The pulley assembly 8 includes: two sets of auxiliary wheels and pulleys; the two sets of auxiliary wheels are rotatably mounted on the mounting frame 1, and the two sets of auxiliary wheels are arranged oppositely in the left and right directions, respectively used to abut against the two sides of the track to clamp the track and prevent derailment; the pulley is rotatably mounted on the mounting frame 1 for abutting against one side of the track in the up and down directions; wherein the two pulley assemblies 8 are arranged at intervals in the front and back directions, and the second drive motor 9 is connected to one of the pulleys in the two pulley assemblies 8. The second drive motor 9 drives the pulley to roll, so that the transport vehicle 100 moves along. The forward and reverse rotation of the second drive motor 9 can control the transport vehicle 100 to move forward or backward. The speed of the second drive motor 9 is proportional to the moving speed of the transport vehicle. The transport vehicle 100 has the functions of slow accompanying, fast return, and liftable tray 3.

[0042] To control the speed and direction of the transport vehicle 100 at different locations on the track, the transport vehicle 100 also includes a barcode reader 10. This barcode reader 10 is mounted on one side of the mounting frame 1 and is electrically connected to the second drive motor 9. This barcode reader 10 is used to read the QR code on the track in real time, identifying the vehicle's position and enabling it to slow down and stop based on the location.

[0043] In order to prevent the transport vehicle 100 from colliding with the transport vehicles 100 in front and behind, causing accidents and damage to the equipment, the transport vehicle 100 also includes a buffer 11 and a proximity switch 12. The buffer 11 and the proximity switch 12 are installed on at least one side of the mounting frame 1 in the front-to-back direction. When two transport vehicles 100 collide, the buffer 11 and the proximity switch 12 are triggered. The buffer 11 is used to provide a buffering effect to protect the equipment, and the proximity switch 12 is electrically connected to the second drive motor 9 to control the second drive motor 9 to stop.

[0044] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
