Description

Technical Field

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

[0002] As the automotive market continues to expand, competition in the industry is becoming increasingly fierce. Therefore, reducing costs and improving equipment availability have become key objectives for major automakers. In automotive welding production workshops, robots and workbenches need to be replaced after prolonged use to reduce equipment failure rates.

[0003] In existing technology, when replacing robots and platforms, the robots and platforms are first removed from the welding line, and then lifted out by a large crane. However, some robots or platforms are located in areas with narrow passages or large obstacles directly above them, which makes it impossible for the crane to enter and complete the lifting and transportation. This makes the transportation of robots or platforms extremely difficult.

[0004] Therefore, it is necessary to provide a new handling device to solve the above-mentioned technical problems. Utility Model Content

[0005] The main objective of this invention is to propose a handling device that aims to improve the technical problem of difficult handling by robots or platforms in the prior art.

The transport trolley further includes a second positioning pin, the second positioning pin being used to pass through the third mounting hole and be installed in the second mounting hole.

[0015] In one embodiment, there are two second positioning plates arranged diagonally, and there are two third positioning plates arranged diagonally. There are also two second positioning pins, and the two second positioning pins, the two second positioning plates, and the two third positioning plates are arranged in a one-to-one correspondence.

[0016] In one embodiment, the transport trolley further includes handrails, the number of which is at least two, the two handrails are respectively disposed at both ends of the first body, and both handrails extend upward.

[0031] Please see Figures 1 to 5This utility model proposes a handling device 100 for handling robots or gantry frames in a welding line. It includes a transport trolley 1 and a handling assembly 2. The transport trolley 1 includes a first body 11 and multiple wheels 12 disposed at the bottom of the first body 11. The wheels 12 are arranged in a rectangular pattern. Two spaced-apart slides 111 are formed on the top of the first body 11. The handling assembly 2 includes a second body 21, multiple first steel wheels 22, and multiple second steel wheels 23. The first steel wheels 22 and multiple second steel wheels 23 are symmetrically arranged on both sides of the second body 21. The diameters of the first steel wheels 22 and second steel wheels 23 are equal. The first steel wheel 22 and the second steel wheel 23 are slidably installed on one of the slide rails 111, and the second steel wheel 23 are slidably installed on the other slide rail 111. The first steel wheel 22 and the second steel wheel 23 can be used to slide onto the welding line track. The top of the second body 21 is used to mount the frame or robot. Specifically, the multiple first steel wheels 22 and the multiple second steel wheels 23 of the handling assembly 2 are slidably installed on the two slide rails 111 respectively, and the center distance between the first steel wheel 22 and the second steel wheel 23 is consistent with the center distance between the two slide rails 111, and the center distance between the first steel wheel 22 and the second steel wheel 23 is consistent with the center distance of the welding line track. When it is necessary to handle the robot or frame... During the process, the operator pushes the transport trolley 1 towards the welding line track until it aligns with the track. At this point, the two slide rails 111 align with the track. The operator then pushes the transport assembly 2 onto the two slide rails 111 until it reaches the welding line track. The transport assembly 2 continues to slide along the track until it reaches the position where the robot or platform needs to be replaced. A simple lifting device is then used to hoist the old robot or platform onto the transport assembly 2. The operator then continues to push the transport assembly 2 along the welding line track. The robot or platform is moved to the very end of the welding line and then removed by a forklift, thus removing the robot or platform from the welding line. In this embodiment, a slide rail 111 is set on the transport trolley 1, and a first steel wheel 22 and a second steel wheel 23 are set on the handling component 2. After the transport trolley 1 is connected to the welding line, the handling component 2 can slide on the slide rail 111 onto the welding line track. In this way, the handling component 2 can move to the robot or platform that needs to be moved and remove the robot or platform from the welding line. There is no need to use a crane to lift the robot or platform, so there will be no difficulty in handling.

[0032] Please see Figure 4In one embodiment, the top of the second body 21 is formed with a first mounting position 211, a second mounting position 212, a third mounting position 213, and a fourth mounting position 214. There are four of each of the four mounting positions 211, 212, 213, and 214. The four mounting positions 211, 212, 313, and 214 are arranged in a rectangle. The length of the rectangle formed by the four mounting positions 211 is less than the length of the rectangle formed by the four mounting positions 212, the length of the rectangle formed by the four mounting positions 212 is less than the length of the rectangle formed by the four mounting positions 213, and the length of the rectangle formed by the four mounting positions 213 is less than the length of the rectangle formed by the four mounting positions 214. When the handling component 2 moves to the location of the platform to be handled, the first mounting position 211, the second mounting position 212, the third mounting position 213, and the fourth mounting position 214 are selected according to the size of the platform. This allows the handling component 2 to support platforms of different sizes. Furthermore, since the mounting positions are all arranged in a rectangular pattern, all four corners of the platform can be fixed, making the connection between the platform and the second body 21 more secure. By setting four sets of rectangular mounting positions of different sizes, namely the first mounting position 211 to the fourth mounting position 214, it can adapt to different specifications of platforms or robot bases, significantly improving the versatility of the handling component 2. The rectangular layout design of the mounting positions can precisely fix the four corners of the platform, avoiding displacement or overturning caused by uneven force during handling, and enhancing load stability. At the same time, the tiered mounting size design can cover the handling needs from light to heavy equipment, reducing the development cost of special tooling.

[0033] Please see Figure 4 and Figure 5 In one embodiment, the handling assembly 2 further includes a rotary bearing 24 and a robot mounting plate 25. The rotary bearing 24 is rotatably mounted on the top of the second body 21, and the robot mounting plate 25 is mounted on the end of the rotary bearing 24 away from the second body 21. The robot mounting plate 25 is used to mount the robot. The rotary bearing 24 is connected to the robot mounting plate 25, so that when the rotary bearing 24 rotates, the robot mounting plate 25 will also rotate, thus enabling the robot mounting plate 25 to have a 360° rotation function. When the handling assembly 2 carries the robot and pushes it out along the welding line track, the robot's posture may sometimes interfere with obstacles on both sides of the welding line track. Therefore, the rotary bearing 24 can be rotated at a certain angle to allow the robot mounted on the robot mounting plate 25 to avoid obstacles.

[0034] Please see Figure 4 and Figure 5In one embodiment, the transport assembly 2 further includes two lifting seats 26, both of which are mounted on the top of the second body 21 and are spaced apart along the length of the second body 21. The platform may be located on a low chassis; therefore, the two lifting seats 26 are provided so that the low-chassis platform can be mounted on the two lifting seats 26, thus preventing interference between the low-chassis platform and the robot mounting plate 25.

[0035] Please see Figure 2 In one embodiment, a first positioning plate 112 is provided on the first body 11, and a first mounting hole 112a is formed on the first positioning plate 112. The transport trolley 1 also includes a first positioning pin, which is used to pass through the first mounting hole 112a and be installed in a fixing hole in the ground. Through the cooperation between the first positioning plate 112 and the fixing hole in the ground, combined with the locking function of the first positioning pin, the transport trolley 1 can be quickly fixed to the ground, preventing the trolley from shifting due to external forces when welding the rails of the assembly line, and ensuring the stability and safety of the transportation process. It is especially suitable for working environments with uneven ground or vibration.

[0036] Please see Figure 2 In one embodiment, there are two first positioning plates 112, which are arranged diagonally. There are also two first positioning pins, which correspond one-to-one with the two first positioning plates 112. The two diagonally arranged first positioning plates 112 and the two first positioning pins form a symmetrical locking structure, which can balance the force distribution of the transport trolley 1 when it is fixed, avoid the trolley tilting or shaking caused by unilateral locking, and further improve the reliability of fixing.

[0037] Please see Figure 2 and Figure 4 In one embodiment, the first body 11 is further provided with a second positioning plate 113, on which a second mounting hole 113a is formed. The second body 21 is provided with a third positioning plate 215, on which a third mounting hole 215a is formed. The transport trolley 1 also includes a second positioning pin, which is used to pass through the third mounting hole 215a and install itself in the second mounting hole 113a. When the transport assembly 2 is slidably mounted on the two slide rails 111 via the first steel wheel 22 and the second steel wheel 23, the second positioning plate 113 and the third positioning plate 215 are locked together by the second positioning pin. This locks the transport assembly 2 on the transport trolley 1, preventing the transport assembly 2 from sliding when the transport trolley 1 is moved, thus preventing injury to the operator.

[0038] Please see Figure 2 and Figure 4In one embodiment, there are two second positioning plates 113, which are arranged diagonally. There are also two third positioning plates 215, which are arranged diagonally. There are also two second positioning pins. The two second positioning pins, the two second positioning plates 113, and the two third positioning plates 215 are arranged in a one-to-one correspondence. This diagonal locking design further optimizes the force balance, preventing the transport assembly 2 from shifting or overturning due to unilateral pressure during sliding. It is particularly suitable for long-distance, high-load transport tasks, enhancing the overall rigidity and stability of the system.

[0039] Please see Figure 1 and Figure 2 In one embodiment, the transport trolley 1 further includes handrails 13, with at least two handrails 13 respectively located at both ends of the first body 11, and both handrails 13 extending upwards. The upward-extending handrails 13 at both ends are ergonomically designed, facilitating the operation of the transport trolley 1 from different directions, improving maneuverability and labor-saving. The multiple handrails 13 design can also serve as gripping points during emergency braking, enhancing operational safety.

[0040] In one embodiment, the transport trolley 1 further includes multiple mounting seats 14 and multiple brake pads. The mounting seats 14 are arranged in a rectangular shape at the bottom of the first body 11. The number of mounting seats 14, the number of brake pads, and the number of wheels 12 are equal. The wheels 12 are rotatably mounted on the mounting seats 14, and each wheel 12 corresponds to one of the mounting seats 14. The brake pads are rotatably mounted on the mounting seats 14 and can rotate to abut against the wheels 12 to prevent them from rotating. Each wheel 12 is equipped with an independent brake pad, which locks the wheel by rotating and abutting against it, quickly securing the transport trolley 1 and preventing it from accidentally sliding on slopes or in vibrating environments. The rectangular arrangement of the mounting seats 14 and the one-to-one correspondence between the wheels 12 ensures uniform distribution of braking force, improves braking reliability, and facilitates maintenance and replacement.

[0041] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
