[0038] like Figures 1 to 3 As shown, this embodiment provides a trolley flipping device, which includes a base 10, two sliding support seats 20, a clamping structure 30 and a driving structure 50. The sliding support seats 20 are slidably arranged on the base 10, and the two sliding support seats 20 can move closer to or away from each other. A clamping structure 30 is rotatably arranged on each sliding support seat 20, and the clamping structure 30 is used to clamp the trolley; the driving structure 50 is connected to the clamping structure 30 to drive the clamping structure 30 to rotate to flip the trolley.

[0039] By setting two sliding support seats 20 and setting a clamping structure 30 on each sliding support seat 20, the two sliding support seats 20 can move closer to or farther away from each other, thereby changing the distance between the clamping structures 30 on the two sliding support seats 20, so that the two clamping structures 30 can clamp trolleys of different sizes; by rotatably setting the clamping structure 30 on the sliding support seat 20, and setting a driving structure 50 to drive the clamping structure 30 to rotate, thereby flipping the trolley, instead of manually lifting and flipping or hoisting and flipping, the operation steps are simplified to facilitate operation, improve installation efficiency, and avoid safety problems during manual lifting and flipping or hoisting and flipping.

[0040] Before use, control the two sliding support seats 20 to slide in the direction away from each other to reserve space for the installation of the trolley, place the bottom plate A and the two side sealing plates B connected to the bottom plate A between the two sliding support seats 20, control the two sliding support seats 20 to slide in the direction close to each other, and fix the two side sealing plates B on the clamping structures 30 on the two sliding support seats 20 respectively, thereby completing the clamping action.

[0041] It is understandable that when two clamping structures 30 clamp the trolley, the driving structure 50 can only connect to and drive one of the clamping structures 30 to rotate, thereby driving the trolley and the other clamping structure 30 to rotate. In other embodiments, the driving structure 50 can also be set to drive the two clamping structures 30 to rotate synchronously.

[0042] Specifically, the base 10 is in the shape of a flat plate and is used to be fixed on the ground or a tooling platform; the base 10 can be fixed by welding or by assembly.

[0043] To enable relative sliding between the base 10 and the sliding support 20, the base 10 is provided with a slide rail 11, on which the sliding support 20 slides. In this embodiment, two slide rails 11 are provided side by side, spaced apart and arranged in parallel, with each sliding support 20 sliding on both slide rails 11. The two slide rails 11 arranged side by side help ensure the stability of the sliding support 20 during sliding.

[0044] Optionally, the base 10 is provided with a stopper located at the end of the slide rail 11 for limiting the position of the sliding support 20; a stopper is provided at both ends of each slide rail 11. The provision of the stopper effectively prevents the sliding support 20 from excessive movement and thus disengagement from the slide rail 11.

[0045] In order to position the sliding support seat 20, a positioning bar 12 is also provided on the base 10. The sliding support seat 20 is provided with a fastener. The positioning bar 12 is provided with a positioning hole. The fastener can be inserted into the positioning hole and threadedly connected to the positioning hole. In this embodiment, two positioning bars 12 are provided. The two positioning bars 12 are located on the same straight line and are both located between the two slide rails 11. The fasteners are bolts. Multiple positioning holes are provided at intervals along the length of the slide rail 11. By providing positioning holes and fasteners, after adjusting the positions of the two sliding support seats 20, the fasteners are used to fix the sliding support seats 20 to the base 10 to prevent the sliding support seats 20 from shifting after adjustment, thereby ensuring that the clamping structures 30 on the two sliding support seats 20 can work together to clamp the trolley. The number of positioning holes can be increased or decreased according to the actual size of the positioning bars 12.

[0046] Specifically, the sliding support base 20 includes a sliding member 21 and a column 22. The sliding member 21 is slidably engaged with the slide rail 11. The column 22 is detachably mounted on the sliding member 21. The clamping structure 30 is mounted on the column 22. By detachably mounting the column 22 on the sliding member 21, the sliding member 21 and the column 22 can be easily disassembled and replaced. By replacing the column 22 with a different length, the height of the clamping structure 30 can be adjusted, thereby improving applicability. In addition, if the sliding member 21 becomes worn, it can be removed for maintenance.

[0047] In this embodiment, the sliding member 21 includes a support plate 211 and a slider 212. The column 22 is fixed to the support plate 211 via hexagonal bolts. The column 22 is disposed on the top surface of the support plate 211, and the slider 212 is disposed on the bottom surface of the support plate 211. By using bolts to detachably fix the column 22 to the support plate 211, good durability and reliability are ensured, and maintenance and repair are facilitated.

[0048] Optionally, two rows of sliders 212 are provided on the bottom surface of the support plate 211, and the two rows of sliders 212 are arranged at intervals and respectively slide with the two rows of slide rails 11; there are two sliders 212 in each row; the positioning bar 12 is located in the middle of the base 10, and the fastener is passed through the support plate 211 and the end is threadedly engaged with the positioning hole of the positioning bar 12.

[0049] It is understandable that the number of sliders 212 in each row can be one, two, or more. By providing multiple sliders 212, the sliding support base 20 can only slide along the slide rail 11, and the sliders 212 and the slide rail 11 will not separate during relative sliding, which helps to ensure the support stability and smooth sliding of the sliding support base 20. By providing a positioning bar 12 in the middle of the base 10, the positioning bar 12 is located between the two slide rails 11, and the structure is compact and space-saving, which facilitates the positioning of the sliding support base 20.

[0050] Furthermore, the trolley flipping device also includes a flipping structure 40. The two clamping structures 30 are respectively a first clamping structure 30a and a second clamping structure 30b. The first clamping structure 30a is rotationally connected to the corresponding sliding support base 20 via the flipping structure 40; the second clamping structure 30b is connected to the corresponding sliding support base 20 via a driving structure 50. By providing the flipping structure 40 and the driving structure 50 in coordination, the flipping structure 40 supports the first clamping structure 30a and the first clamping structure 30a can rotate freely. The first clamping structure 30a and the second clamping structure 30b clamp the trolley. When the driving structure 50 drives the second clamping structure 30b to rotate, it also drives the trolley and the first clamping structure 30a to rotate accordingly. The structure is simple and easy to control.

[0051] Specifically, the flip structure 40 includes a bearing seat 41, a bearing 42, and a rotating shaft 43. The bearing seat 41 is mounted on the column 22 of the sliding support 20, and the bearing 42 is embedded in the bearing seat 41. One end of the rotating shaft 43 is connected to the bearing 42, and the other end is connected to the first clamping structure 30a. By arranging the bearing seat 41, the bearing 42, and the rotating shaft 43, the flip structure 40 can provide flexible support for the first clamping structure 30a, allowing the first clamping structure 30a to rotate freely.

[0052] In this embodiment, two bearing seats 41 are arranged side by side and spaced apart. Each bearing seat 41 is provided with a bearing 42, and a rotating shaft 43 is connected to the two bearings 42. The arrangement of two bearings 42 and the rotating shaft 43 helps to ensure the stability of the overall structure.

[0053] The drive structure 50 includes a reducer 52 and an operating handwheel 51. The operating handwheel 51 is connected to the input shaft of the reducer 52, and the second clamping structure 30b is connected to the output shaft of the reducer 52. The operating handwheel 51 can drive the reducer 52 to rotate the second clamping structure 30b. By arranging the operating handwheel 51 and the reducer 52, manually turning the operating handwheel 51 is convenient and flexible. The reducer 52 can increase torque while reducing the output speed, allowing the operator to directly and accurately control the output of the reducer 52 and make precise adjustments. The combination of the bearing 42 and the reducer 52 reduces vibration and noise generated when turning the trolley, preventing noise from harming the operator and causing environmental pollution.

[0054] In this embodiment, the reducer 52 is a worm gear reducer; the operating handwheel 51 is detachably connected to the input shaft of the reducer 52. The operating handwheel 51 can be inserted into the worm of the worm gear reducer and fixed with bolts. By providing a worm gear reducer, the worm gear reducer has a self-locking function, which can lock itself after rotation to prevent reverse rotation and improve operational safety. By providing a detachable connection between the operating handwheel 51 and the worm gear reducer, the operating handwheel 51 can be installed on the worm gear reducer when needed, and the operating handwheel 51 can be removed after use. After removal, the worm wheel and worm in the worm gear reducer will no longer rotate.

[0055] Optionally, the first clamping structure 30a is detachably connected to the rotating shaft 43, and the second clamping structure 30b is detachably connected to the output shaft of the reducer 52. By detachably connecting the first clamping structure 30a to the flipping structure 40 and the second clamping structure 30b to the driving structure 50, replacement and maintenance of the trolley flipping device are facilitated.

[0056] Optionally, both the first clamping structure 30a and the second clamping structure 30b include a clamping plate 31, each of which is provided with a positioning member 311 for connection to the trolley. The clamping plates 31 of the first clamping structure 30a and the second clamping structure 30b are arranged opposite each other. The positioning members 311 provided on the clamping plates 31 facilitate the installation of the side sealing plates B on both sides of the trolley on the clamping plates 31, ensuring accurate installation of the trolley. The positioning members 311 may be positioning pins, positioning columns, or positioning screws.

[0057] In this embodiment, the bearing seat 41 and the reducer 52 are respectively fixed to the columns 22 of the two sliding support seats 20 by hexagon socket bolts. The clamping plate 31 of the first clamping structure 30a is detachably connected to the rotating shaft 43 by hexagon socket bolts, and the clamping plate 31 of the second clamping structure 30b is detachably connected to the output shaft of the reducer 52 by hexagon socket bolts. The clamping plate 31 of the second clamping structure 30b can rotate under the drive of the output shaft of the reducer 52, thereby driving the handcart and the clamping plate 31 of the first clamping structure 30a to rotate. By directly mounting the clamping plates 31 of the first clamping structure 30a and the second clamping structure 30b on the corresponding flipping structure 40 and driving structure 50, when the handcart flips, the meshing angle between the worm wheel and the worm of the worm gear reducer is small and the meshing area is large, so that the worm gear reducer has a high load-bearing capacity without reducing transmission efficiency.

[0058] The following is the specific use process of the trolley turning device:

[0059] During use, the operator first fixes the base 10 on the ground or work platform by welding or assembly, controls the two sliding support seats 20 to slide away from each other to reserve space for the installation of the trolley, places the bottom plate A of the trolley and the two side sealing plates B connected to the bottom plate A between the two sliding support seats 20, controls the two sliding support seats 20 to slide towards each other, and uses bolts and nuts to fix the side sealing plates B on both sides of the trolley on the clamping plates 31 of the first clamping structure 30a and the second clamping structure 30b respectively. After fixing, use bolts to fix the two sliding support seats 20 on the corresponding positioning bars 12.

[0060] The operator assembles the relevant components of the switch according to the assembly process. After assembling the components above the base plate A, the operator turns the operating handwheel 51, and the operating handwheel 51 drives the worm gear reducer to rotate and then drives the second clamping structure 30b to rotate. At the same time, the flipping structure 40 provides flexible support for the first clamping structure 30a, so that the clamping plates 31 of the first clamping structure 30a and the second clamping structure 30b can clamp the trolley and flip the trolley. After the operator selects a suitable position, he stops shaking the operating handwheel 51. Since the worm gear reducer has a self-locking function, it can lock itself after rotation to prevent reverse rotation, thereby improving operational safety. After use, the trolley can be removed from the clamping plate 31 of the trolley flipping device.

[0061] The worm gear and worm shaft of the worm gear reducer feature a self-locking function, locking automatically after rotation. This simplifies operation, reduces labor, and avoids safety issues associated with hoisting or manual turning. Furthermore, because the worm gear reducer serves as the core rotating mechanism, the overall structure is compact and simple, making it easy to install and maintain, thereby reducing the subsequent maintenance costs of the trolley turning device. Because all components of the trolley turning device are fastened with bolts, the entire device has a strong load-bearing capacity and stable and reliable operation.

[0062] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
