Description

Technical Field

[0001] This utility model relates to the field of transfer cart technology, specifically a transfer cart. Background Technology

[0002] In our current workpiece production process, the grinding and welding processes are primarily performed manually. The specific workflow involves workers manually moving the workpiece to a horizontally placed, fixed platform, where grinding or welding is then carried out. Throughout the entire operation, adjusting the workpiece's orientation is entirely done manually.

[0003] However, this traditional operating method has many drawbacks in actual operation: Because the workpieces are generally quite heavy, workers not only need to move them from storage to the work platform during operation, but also frequently flip and rotate them to meet the processing needs of different parts during grinding or welding. This results in high labor intensity.

[0004] Moreover, existing horizontal fixed work platforms offer extremely limited space for workpiece posture adjustment. Once the workpiece is placed on the platform, its posture is relatively fixed, making it difficult to flexibly adjust it to the optimal processing position according to the specific requirements of grinding or welding.

[0005] To address this, a transfer trolley is provided as a platform for transferring and placing workpieces. Utility Model Content

[0006] The purpose of this utility model is to provide a transfer trolley to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a transfer trolley, comprising: a lower frame, a rotating bracket rotatably mounted at the top center of the lower frame, the rotating bracket being U-shaped, bearing seats at both ends of the top of the rotating bracket, a flipping bracket rotatably mounted between the bearing seats, a flipping positioning disc fixed on one side of the flipping bracket, a flipping positioning cylinder mounted on one side of the rotating bracket, a positioning hole cooperating with the flipping positioning cylinder on one side of the flipping positioning disc, the flipping bracket being U-shaped, a workpiece support block fixed at one top end of the flipping bracket, and a clamping plate mounted at the other top end.

[0008] Furthermore, a lifting rod is provided inside one end of the flipping bracket, and a crossbar is fixed to the top of the lifting rod. There are two clamping plates, which are respectively fixed to the top two sides of the crossbar.

[0009] Furthermore, a locking screw is provided on the outer wall of one end of the flipping bracket, and one end of the locking screw can abut against the outer wall of the lifting rod.

[0010] Furthermore, the top two sides of the crossbar are provided with strip-shaped through grooves at the clamping plate mounting position, and the clamping plate and the crossbar are connected by bolts.

[0011] Furthermore, a support base is fixed at the center of the bottom of the flipping bracket, a fixed plate is provided on the top of the support base, a handle is rotatably provided on one side of the fixed plate, a support rod is rotatably provided on one side of the fixed plate, a positioning post is fixed at one end of the support rod, and a connecting rod is provided between the handle and the support rod.

[0012] Furthermore, a rotating platform is provided at the center of the top of the lower frame, and the center of the bottom of the rotating bracket is fixed to the top surface of the rotating platform.

[0013] Furthermore, a rotary positioning cylinder is provided at the top of the lower frame below the rotary platform.

[0014] Furthermore, the lower frame is equipped with omnidirectional brake casters at the four corners of its bottom.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the design of a lower frame, a rotating bracket, and a tilting bracket, enables manual hoisting of workpieces onto the top of the transfer trolley during use. One end of the workpiece is supported by a workpiece support block, and the workpiece is limited by a positioning block protruding from the workpiece support block that mates with the workpiece. The other end of the workpiece is placed on a crossbar, and the other end of the workpiece is clamped by adjusting the position of the clamping plates on both sides. Then, by rotating the handle, the support rod is rotated through the connecting rod, thereby causing the positioning column to rise or fall, locking one end of the positioning column into the corresponding positioning hole on the workpiece. Multi-point positioning of the workpiece is achieved through the workpiece support block, clamping plates, and positioning column, thus fixing the workpiece. Then, the transfer trolley is moved to the grinding or welding station. When the workpiece needs to be flipped or rotated, the rotation of the workpiece on the horizontal plane is adjusted by rotating the rotary support. The rotation angle is fixed by the piston rod of the rotary positioning cylinder abutting against the rotary platform. The workpiece is flipped by manually rotating the flipping support. The flipping angle is fixed by the piston rod of the flipping positioning cylinder engaging with the positioning hole on the flipping positioning plate, which facilitates the grinding or welding of the workpiece. The workpiece is flipped and rotated by the flipping support and rotary support on the transfer trolley, which saves manpower and can adjust the position of the workpiece to a suitable angle, which is conducive to improving the quality and efficiency of subsequent grinding or welding.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a transfer trolley, including a lower frame 1. The lower frame 1 serves as the basic support structure for the entire transfer trolley, providing a stable mounting platform for other components on the trolley and ensuring the overall structural stability of the trolley. A rotating bracket 5 is rotatably mounted at the top center of the lower frame 1. This design allows the rotating bracket 5 to rotate and adjust the workpiece it carries on a horizontal plane. The rotating bracket 5 is U-shaped, providing space for the installation of other internal components.

[0021] The rotary support 5 has bearing seats 6 at both ends of its top, and a flip support 7 is rotatably mounted between the bearing seats 6. The bearing seats 6 provide precise support and guidance for the rotation of the flip support 7, ensuring that the flip support 7 can rotate smoothly and steadily around its axis. A flip positioning plate 9 is fixed to one side of the flip support 7, and a flip positioning cylinder 8 is provided on one side of the rotary support 5. A positioning hole 10 is provided on one side of the flip positioning plate 9 to cooperate with the flip positioning cylinder 8. When the flip support 7 rotates the workpiece to the required angle, the piston rod of the flip positioning cylinder 8 can extend and engage with the positioning hole 10 on the flip positioning plate 9. This design achieves precise fixation of the flip angle of the flip support 7, ensuring that the workpiece can be stably maintained at the adjusted flip angle during grinding or welding, and will not rotate unexpectedly due to external factors, thereby ensuring the accuracy and quality of processing.

[0022] The flipping bracket 7 is U-shaped, with a workpiece support block 14 fixed to one end of its top and a clamping plate 13 at the other end. The workpiece support block 14 provides stable support for one end of the workpiece, and its protruding positioning block, which mates with the workpiece, provides initial positioning to prevent the workpiece from sliding or shifting during support. The clamping plate 13 clamps the other end of the workpiece, thus fixing both ends of the workpiece in conjunction with the workpiece support block 14, ensuring the stability of the workpiece during transport and processing.

[0023] The tilting bracket 7 has a lifting rod 11 inside one end, with a crossbar fixed to the top of the lifting rod 11. Two clamping plates 13 are fixed to the top of the crossbar on both sides. A locking screw 12 is provided on the outer wall of one end of the tilting bracket 7, with one end of the screw 12 abutting against the outer wall of the lifting rod 11. The lifting rod 11 allows the crossbar and the clamping plates 13 to be adjusted vertically. This design allows for flexible adjustment of the clamping plate 13 position according to the height of different workpieces, enabling accurate clamping of the workpieces and improving the adaptability of the transfer trolley to different workpiece specifications, thus expanding its application range. After the lifting rod 11 is adjusted to the appropriate height, tightening the locking screw 12 secures one end against the outer wall of the lifting rod 11, fixing its position and preventing accidental movement due to vibration or other reasons during transfer or processing, ensuring the stability of the clamping plates 13 in clamping the workpiece.

[0024] The top two sides of the crossbar have strip-shaped slots at the mounting points of the clamping plate 13, and the clamping plate 13 is connected to the crossbar by bolts. The design of the strip-shaped slots allows the clamping plate 13 to be adjusted horizontally on the crossbar. By loosening the bolts, the position of the clamping plate 13 can be moved along the strip-shaped slots to accommodate workpieces of different widths, and then the bolts can be tightened to fix the clamping plate 13. This structure further improves the adaptability of the transfer trolley to workpieces of different specifications, ensuring accurate and stable clamping of various workpieces.

[0025] A support base 15 is fixed at the center of the bottom of the flipping bracket 7. A fixing plate 16 is provided on the top of the support base 15. A handle 17 is rotatably mounted on one side of the fixing plate 16, and a support rod 19 is rotatably mounted on the other side. A positioning post 20 is fixed to one end of the support rod 19. A connecting rod 18 is provided between the handle 17 and the support rod 19. The support base 15 provides a stable support foundation for the fixing plate 16. By rotating the handle 17, the connecting rod 18 can be moved, which in turn drives the support rod 19 to rotate, causing the positioning post 20 to rise or fall. When the workpiece is placed on the transfer trolley, one end of the positioning post 20 is engaged in the corresponding positioning hole on the workpiece, cooperating with the workpiece support block 14 and the clamping plate 13 to achieve multi-point positioning of the workpiece. This further enhances the fixing effect of the workpiece on the transfer trolley, preventing the workpiece from shaking or shifting during transportation or processing, and ensuring the accuracy of processing.

[0026] A rotating platform 3 is located at the top center of the lower frame 1, and the bottom center of the rotating bracket 5 is fixed to the top surface of the rotating platform 3. A rotating positioning cylinder 4 is located below the rotating platform 3 at the top of the lower frame 1. The rotating platform 3 provides precise support and a rotational foundation for the rotating bracket 5, ensuring that the rotating bracket 5 can rotate smoothly and stably around its center. This design makes the rotation adjustment of the workpiece on the horizontal plane more precise and reliable, facilitating accurate adjustment of the workpiece to the appropriate grinding or welding angle. When the rotating bracket 5 rotates the workpiece to the required horizontal angle, the piston rod of the rotating positioning cylinder 4 extends and abuts against the rotating platform 3. This abutment method fixes the rotation angle of the rotating bracket 5, preventing accidental rotation of the rotating bracket 5 due to external factors during grinding or welding, thus ensuring the stability of the workpiece in the horizontal direction and improving processing quality.

[0027] The lower frame 1 is equipped with omnidirectional brake casters 2 at its four corners. The omnidirectional brake casters 2 allow the transfer trolley to move flexibly in all directions, facilitating the transfer of workpieces to different grinding or welding stations. At the same time, the braking function can fix the trolley after it reaches the designated position, preventing the trolley from moving during processing, ensuring the safety and stability of processing, and improving work efficiency.

[0028] When using the transfer trolley, the workpiece is manually hoisted to the top of the transfer trolley. One end of the workpiece is supported by the workpiece support block 14, and the workpiece is limited by the positioning block protruding on the workpiece support block 14 that cooperates with the workpiece. The other end of the workpiece is placed on the crossbar. By adjusting the position of the clamping plates 13 on both sides, the other end of the workpiece is clamped. Then, by rotating the handle 17, the support rod 19 is rotated through the connecting rod 18, thereby causing the positioning column 20 to rise or fall, and one end of the positioning column 20 is locked in the corresponding positioning hole of the workpiece. The workpiece support block 14, clamping plates and positioning column 20 achieve multi-point positioning of the workpiece and fix the workpiece. Then, the transfer trolley is moved to the grinding or welding station. When it is necessary to flip or rotate the workpiece, the rotation of the workpiece on the horizontal plane is adjusted by rotating the rotary support 5. The rotation angle is fixed by the piston rod of the rotary positioning cylinder 4 abutting against the rotary platform 3. The workpiece is flipped by manually rotating the flipping support 7. The flipping angle is fixed by the piston rod of the flipping positioning cylinder 8 engaging with the positioning hole 10 on the flipping positioning plate 9. This facilitates the grinding or welding of the workpiece. The workpiece is flipped and rotated by the flipping support 7 and the rotary support on the transfer trolley. This saves manpower and allows the workpiece to be adjusted to a suitable angle, which is beneficial to improving the quality and efficiency of subsequent grinding or welding.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
