[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0027] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, and back), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0028] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0029] In an automobile production workshop, the body is assembled from various components, including the front and rear longitudinal beams, wheel arches, B-pillars, C-pillars, fenders, and four-door hoods. Due to space limitations, components must be transported between process steps between various engineering islands. Optimizing handling equipment and improving efficiency are crucial for eliminating bottlenecks in production. Within the factory, handling trolleys are typically used to transport components, improving efficiency, reducing costs, and reducing the load on the factory floor. However, due to the specific nature of this job, workers must frequently bend over for extended periods of time and perform upper body loads. The difficulty of these upper body tasks can easily lead to joint inflammation and musculoskeletal disorders, making them unable to perform this job long-term. This significantly impacts production and complicates management for on-site managers, leading to long-term production waste and increased costs.
[0030] After careful research, the applicant discovered that each time the transport trolley and the tractor were used for transport, the operator had to bend over to unblock the material. Furthermore, since the transport trolley could not be moved into position all at once, the operator had to manually push the 150kg transport trolley about 6 meters to allow it to move to the material rack and dock with the rack. Furthermore, adjusting the docking position between the transport trolley and the rack took 120 seconds of work. After the material was loaded and unloaded, the operator had to manually push the trolley and the material on it about 6 meters back to the unblocking position, then bend over to connect the tractor and pull the transport trolley again. The entire operation process required the operator to bend over for a long time and frequently, and placed a heavy load on the operator's upper limbs. This could easily lead to joint inflammation and musculoskeletal diseases due to excessive labor intensity, making it impossible for the operator to work in this position for a long time.
[0031] When improving the problems with the above-mentioned transport trolleys, in actual production, the vast majority of companies do not conduct on-site problem discovery and improvement work. Very few companies will adopt the traditional method of increasing the number of workers to reduce the workload of a single person to meet production needs. This solution has the following disadvantages: First, the production effect is poor and the cost is high. It is difficult to achieve the desired efficient and low-cost transport effect. The operator's bending over to remove the card and the long walking distance for pushing still exist. The working environment has not been improved, and there will still be a waste of working hours. The safety hazards of pushing the transport trolleys have not been eliminated. Second, the popularity rate is not high. The method of increasing the number of people for transport cannot meet the implementation of various production lines. The equipment has high energy consumption and there is a serious waste of costs.
[0032] The main purpose of the utility model is to provide a transport trolley to solve the problem of how to reduce the labor intensity of operators and reduce the probability of illness of operators.

The operator only needs to turn the rotating bracket 2 to the loading and unloading direction, and then push the rotating bracket 2 and the adjustment mechanism 3 to move in the left and right directions, so that the first pallet mechanism 5 is docked with the material rack, thereby completing the loading or unloading operation. There is no need to push the entire transport trolley 100 to move and rotate. It is only necessary to push the rotating bracket 2 and the adjustment mechanism 3 to move in the left and right directions, which effectively reduces the labor intensity of the operator and reduces the risk of the operator suffering from joint inflammation and bone diseases due to the difficulty of upper limb operations. After loading and unloading, the rotating bracket 2 and the adjustment mechanism 3 are restored to their original positions, and the transport trolley 100 can be directly towed back by the traction machine without having to bend down again to connect the traction machine and the transport trolley 100.
[0035] The technical solution of the present invention adopts a rotating bracket 2 and an adjusting mechanism 3. When adjusting the docking of the first pallet mechanism 5 with the material rack, it is only necessary to rotate and move the rotating bracket 2 and the adjusting mechanism 3 without pushing the entire transport trolley 100, which reduces the working load, eliminates the operator's bending over to unhook the work, reduces the long-term and high-frequency load pushing, improves the working environment, effectively reduces the labor intensity of the operator, reduces the probability of limb injury and illness due to long-term and repetitive work, reduces the engineering bottleneck problem caused by low operability, makes the working process more humane, improves the safety of the operation, and enables the operator to easily adjust the position of the first pallet mechanism 5, so that the operation is smoother and more efficient.

The rotating member 32 is rotatably connected to the support member 31, and the end of the rotating member 32 away from the support member 31 is connected to the bottom of the rotating bracket 2; specifically, the support member 31 provides support for the rotating member 32, and the support member 31 can move relative to the base 1 in the left and right directions. The rotatable connection between the support member 31 and the rotating member 32 provides a high degree of flexibility, so that the operator can easily adjust the position of the first tray assembly 51, allowing the operator to adjust the position and angle of the first tray assembly 51 as needed, thereby improving the adaptability and practicality of the transport trolley 100; and through the support member 31 and the rotating member 32, the transport operation is simplified, and the operator's physical labor during the transport process is reduced, which helps to reduce the chance of limb injury and illness caused by long-term, high-load operations, improves the transport efficiency, and makes the operation safer. In this embodiment, the adjustment mechanism 3 can adopt a universal coupling, one end of the universal coupling is movably installed on the base 1, and the other end of the universal coupling is connected to the bottom of the rotating bracket 2, thereby realizing the rotation of the rotating bracket 2 and the base 1.
[0038] According to an embodiment of the present invention, a bearing is provided on the support member 31 , and the rotating member 32 includes a rotating shaft. The rotating shaft and the bearing are rotatably connected to realize the rotation of the rotating bracket 2 and the base 1 .
[0039] In one embodiment, a transverse pulley 33 is provided at the bottom of the support member 31, and a transverse guide rail 11 is provided on the base 1. The transverse guide rail 11 is provided along a first direction, and the transverse pulley 33 and the transverse guide rail 11 roll in cooperation to enable the support member 31 to move relative to the base 1 along the first direction; specifically, the rolling cooperation of the transverse pulley 33 and the transverse guide rail 11 can reduce friction, so that the operator can easily push or pull the support member 31 to different positions to meet different transportation requirements, reduce the pushing force, and improve the convenience of operation. The transverse guide rail 11 also helps the transverse pulley 33 to move along a predetermined left and right path, so that the support member 31 is smoother and more stable when moving along the left and right directions on the base 1, and can also ensure the precise control and positioning of the working position of the first tray mechanism 5, and the transverse pulley 33 and the transverse guide rail 11 have a simple structure, stable operation, and are easy to maintain.

[0040] According to one embodiment of the present invention, a transverse slider is provided at the bottom of the support member 31, and a transverse slide rail is provided on the base 1. The transverse slide rail is arranged along a first direction, and the transverse slider and the transverse slide rail slide together to enable the support member 31 to move relative to the base 1 along the first direction; specifically, the transverse slider and the transverse slide rail have a simple structure, stable operation, easy design and manufacturing, convenient for large-scale production, and easy disassembly and maintenance, and can be inspected, cleaned and replaced in time.
[0041] See also Figure 4 and Figure 5 In one embodiment, the rotating bracket 2 has a working position 21, and a sliding groove 22 is provided at the bottom of the rotating bracket 2. A sliding wheel 12 is provided on the side of the base 1 away from the caster 4. The sliding wheel 12 abuts against the sliding groove 22 to support the rotating bracket 2. When the rotating member 32 rotates relative to the support member 31, the sliding wheel 12 rolls with the sliding groove 22. When the rotating bracket 2 rotates to the working position 21, the sliding wheel 12 is located outside the sliding groove 22, so that the support member 31 can move relative to the base 1 along the first direction; specifically, the abutment between the sliding wheel 12 and the sliding groove 22 provides additional supporting force for the rotating bracket 2, thereby enhancing the stability of the entire transport trolley 100, especially when carrying heavy objects, the sliding wheel 12 can reduce The deformation of the rotating bracket 2 due to force is reduced, and the integrity of the structure is maintained; and the sliding groove 22 plays a role of limiting and guiding the sliding wheel 12, so that when the rotating member 32 rotates relative to the support member 31, the sliding wheel 12 can slide along the sliding groove 22, making the rotation of the rotating bracket 2 more stable; the working position 21 is the position when the rotating bracket 2 rotates 90° relative to the base 1.

When loading materials, the first end 5111 can be lifted to dock with the shelf. At this time, the height of the first end 5111 is higher than the height of the second end 5112, so that the material can slide from the first end 5111 to the second end 5112 by its own gravity. When unloading materials, the first end 5111 can be lowered to dock with the shelf. At this time, the height of the first end 5111 is lower than the height of the second end 5112, so that the material can slide from the second end 5112 to the first end 5111 by its own gravity, thereby reducing the labor intensity and time of manual handling.

By lifting or lowering the first end 5111, the materials can move back and forth between the first end 5111 and the second end 5112, thereby completing the loading and unloading of materials.
[0046] In one embodiment, the first tray mechanism 5 also includes a first limit stop rod 54 and a second limit stop rod 55, and the first limit stop rod 54 and the second limit stop rod 55 are both connected to the rotating bracket 2, and the first limit stop rod 54 and the second limit stop rod 55 are spaced apart along the extension direction of the tray assembly 51, and the first limit stop rod 54 and the second limit stop rod 55 are respectively arranged on both sides of the rotating shaft 52, and the first limit stop rod 54 and the second limit stop rod 55 are both used to abut against the bottom of the tray assembly 51; specifically, the first limit stop rod 54 and the second limit stop rod 55 are connected to the rotating bracket 2, for limiting the movement range of the tray assembly 51, and the first limit stop rod 54 and the second limit stop rod 55 are spaced apart along the extension direction of the tray assembly 51, which can ensure that the tray assembly 51 remains on a predetermined path when rotating, prevents the tray assembly 51 from excessive movement or offset during rotation, and provides stable support when the rotation reaches the limit position, reducing the risk of material damage or equipment damage due to improper operation.
[0047] In this embodiment, the height of the first limit stop rod 54 and the second limit stop rod 55 are adjustable. By adjusting the height of the first limit stop rod 54 and the second limit stop rod 55, the rotation position of the material tray assembly 51 can be precisely controlled as needed to ensure the stability and safety of the material during the transportation process, thereby improving the applicability and flexibility of the transportation trolley 100.
[0048] In addition, in this embodiment, the first limit block rod 54 and the second limit block rod 55 can be adjusted by means of a telescopic rod or a slider rail. This embodiment does not limit the specific method of adjusting the height of the first limit block rod 54 and the second limit block rod 55.
[0049] See also Figure 6 In one embodiment, the first tray mechanism 5 further includes a docking guide block 56, which is movably mounted on the rotating bracket 2 so that the docking guide block 56 can move relative to the rotating bracket 2 in a second direction.

In this embodiment, the docking guide block 56 is movably mounted on the rotating bracket 2, so that the tray assembly 51 can dock to material racks at different heights, thereby improving the adaptability and practicality of the transport trolley 100.
[0050] In this embodiment, there is no limitation on the specific connection method between the docking guide block 56 and the rotating bracket 2. A plurality of first through holes may be provided on the rotating bracket 2 in the up and down directions, and a second through hole may be provided on the docking guide block 56. Fasteners are passed through the second through holes and the first through holes at different height positions to adjust the height position of the docking guide block 56 on the rotating bracket 2, thereby meeting the docking requirements of material racks at different height positions.
