Description

Technical Field

[0001] The present invention relates to the technical field of transfer vehicles, in particular to a side fork type lifting and flipping transport vehicle. Background Art

[0002] Moving heavy objects is a time-consuming and labor-intensive task. When the objects are large or heavy, a hand truck is often used to assist in their transport. Hand trucks offer a simple, low-cost design and can be used for shoveling, prying, pushing, or pulling, saving effort and being particularly suitable for moving goods over short distances. During the piano manufacturing process, the piano itself needs to be moved at all times. However, due to its large size and weight, it is difficult to transport, and conventional trucks are difficult to carry. Therefore, an improved truck is needed to meet the needs of piano transportation. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention discloses a side fork type lifting and flipping transport vehicle, which adopts the technical solution that the middle part of the cart body is open and is fixedly connected to slide rails on both sides, a movable base is installed on the slide rails, and the movable base includes two sets of parallel movable bottom plates, rollers are installed at the bottom of the movable bottom plates, and a telescopic leg is vertically fixedly connected to one end, and the telescopic leg is slidably inserted into the leg sleeve. The telescopic leg and the leg sleeve are locked and fixed by a locking nut. Loosening the locking nut can adjust the telescopic length of the telescopic leg, which is convenient for driving the movable bottom plate to make the roller contact the ground or lift it off the ground. A crossbeam is fixedly connected to the top of the leg sleeve, and a guide wheel group is fixedly connected to both ends of the crossbeam. The movable base is installed on the slide rail through the rolling fit of the guide wheel group. A telescopic sleeve is vertically fixedly connected to the middle part of the crossbeam, and the telescopic sleeve includes a fixed sleeve, the lower end of the fixed sleeve is fixedly connected to the crossbeam, and the middle part of the upper end is slidably connected with the telescopic sleeve, and the upper end of the telescopic sleeve is fixedly connected to a top mounting block, and a hydraulic cylinder is installed in the middle of the fixed sleeve and the telescopic sleeve, the lower end of the hydraulic cylinder is fixedly connected to the fixed sleeve, and the upper end is pressed against the end of the telescopic sleeve, the hydraulic cylinder is connected to the hydraulic pump through a hydraulic oil pipeline, and the hydraulic pump controls the hydraulic cylinder to drive the telescopic sleeve to rise and fall, thereby realizing the extension and retraction of the telescopic sleeve, and the hydraulic pump is fixedly mounted on an extension plate fixedly connected to the end of the crossbeam. The middle part of the fixed sleeve is rotatably sleeved with a lower rotating seat, and the side surface of the lower rotating seat is fixedly connected to a pressure pad, and the upper rotating seat is installed at the upper end of the fixed sleeve, and the telescopic sleeve rotatably fits through the upper rotating seat, and the two side surfaces of the upper rotating seat are rotatably connected to the oblique support rod through the rotating shaft. The lifting and turning frame is rotatably mounted on the top mounting block through the pin shaft, and the lifting and turning frame can be vertically rotated around the pin shaft, and the lower end of the lifting and turning frame is pressed against the pressure pad, and the lifting and turning frame can be horizontally rotated on the telescopic sliding sleeve with the telescopic sleeve through the upper rotating seat and the lower rotating seat. During the rotation process, the telescopic sleeve rotates in the fixed sleeve, and the hydraulic cylinder does not rotate.

[0004] The lifting and flipping frame is L-shaped, with a damper locking rod pivotally inserted into its middle. A damper is pivotally mounted on the middle portion of the damper locking rod. The damper is located in the middle of the lifting and flipping frame. The lower end of the lifting and flipping frame is fixedly connected to a support plate. Slotted holes are formed on both sides of the lifting and flipping frame below the top mounting block. The outer shell of the damper is fixedly connected to push-up columns on both sides. Push-up locking blocks are fixedly connected to the damper locking rod. The push-up locking blocks are located on both sides of the damper and correspond to the push-up columns. When the lifting and flipping frame needs to be lifted by the telescopic sleeve, the inclined support rod is not connected to the damper, and the push-up locking blocks press against the push-up columns, thereby locking and fixing the damper. The end of the damper locking rod is fixedly connected to a locking handle, and the end of the diagonal support rod is provided with a hole. When the hydraulic cylinder drives the telescopic sleeve to extend to a certain length, raising the lifting and turning frame to a certain height, the damping connecting shaft passes through the corresponding elongated hole and rotatably engages with the damper and the diagonal support rod, respectively, rotatably engaging the diagonal support rod and the damper. The damper locking rod is rotated by the locking handle to disengage the top pressure locking block from the top pressure column, thereby unlocking the damper. Simultaneously, the hydraulic pump is depressurized to allow the hydraulic cylinder and the telescopic sleeve to retract, thereby rotating the lifting and turning frame from a vertical direction to a horizontal direction. During this process, the telescopic sleeve retracts, and the diagonal support rod rotates under the damping support of the damper.

[0005] As a preferred solution of the present invention, universal wheels are fixedly installed at the four corners of the bottom of the cart body, and the ends are fixedly connected to a connecting sleeve. A telescopic frame is slidably connected in the connecting sleeve. A locking screw is installed with a threaded joint on the side of the connecting sleeve. The end of the locking screw is pressed against the telescopic frame. By loosening the locking screw, the length of the telescopic frame inserted into the connecting sleeve can be adjusted. The end of the telescopic frame is fixedly connected to a plug-in tube, and a handlebar is plugged into the plug-in tube. The handlebar can be removed from the plug-in tube to facilitate the horizontal rotation of the piano on the lifting and flipping frame.

[0006] As a preferred solution of the present invention, the guide wheel group includes a main guide wheel and a side pressure guide wheel. The main guide wheel is located on the outer side of the mounting plate and rolls and presses against the bottom of the slide groove of the slide rail, effectively bearing the downward pressure exerted on the mobile base. The side pressure guide wheel is located at the bottom of the mounting plate and rolls and presses against the side of the slide rail, effectively bearing the horizontal push and pull force exerted on the mobile base, ensuring that the mobile base can move stably on the slide rail.

[0007] Beneficial effects of the present invention: The present invention installs the telescopic slide on a mobile base, and installs the mobile base on the trolley body through a slide rail, so that the telescopic slide can be easily moved left and right on the trolley body through the mobile base, thereby facilitating the loading and unloading of the piano. A lifting and flipping frame is rotatably installed on the telescopic slide. The lifting and flipping frame can not only be lifted and lowered with the telescopic slide, but can also be vertically rotated on the top mounting block. At the same time, it can also be horizontally rotated around the telescopic slide through two rotating seats, so that the piano can be loaded sideways onto the lifting and flipping frame, lifted by a hydraulic cylinder and transferred through the trolley body. After being transferred to the appropriate position, the piano can be flipped 90 degrees by vertically rotating the lifting and flipping frame, so that it can be placed upright on the ground. The entire device has a sophisticated structural design and is easy to operate, making piano transportation more convenient and quick, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] Example 1

[0018] like Figures 1 to 8As shown, a side-fork lift and tilt transporter of the present invention has an opening in the middle of a trolley body 1 and is fixedly connected to slide rails 2 on both sides. A movable base 3 is mounted on the slide rails 2. Universal wheels 101 are fixedly mounted at the four corners of the bottom of the trolley body 1. Connecting sleeves 102 are fixedly connected at the ends. A telescopic frame 103 is slidably connected to the connecting sleeve 102. A locking screw 106 is threadedly mounted on the side of the connecting sleeve 102. The end of the locking screw 106 presses against the telescopic frame 103. Loosening the locking screw 106 allows the insertion length of the telescopic frame 103 into the connecting sleeve 102 to be adjusted. A plug-in tube 104 is fixedly connected to the end of the telescopic frame 103. A handlebar 105 is inserted into the plug-in tube 104. The handlebar 105 can be removed from the plug-in tube 104 to facilitate the horizontal rotation of the piano on the lift and tilt frame 7 and prevent the handlebar 105 from blocking the rotation. The mobile base 3 includes two sets of parallel mobile base plates 301, rollers 302 are installed at the bottom of the mobile base plates 301, and one end is vertically fixedly connected to a telescopic leg 306, and the telescopic leg 306 is slidably inserted into the leg sleeve 307. The telescopic leg 306 and the leg sleeve 307 are locked and fixed by a locking nut 308. By loosening the locking nut 308, the telescopic length of the telescopic leg 306 can be adjusted, which is convenient for driving the mobile base plate 301 to make the roller 302 contact the ground or lift it off the ground. A crossbeam 303 is fixedly connected to the top, and guide wheel groups 304 are fixedly connected to both ends of the crossbeam 303. The guide wheel group 304 includes a main guide wheel 3041 and a side pressure guide wheel 3042. The main guide wheel 3041 is located on the outer side of the mounting plate and rolls against the bottom of the slide groove of the slide rail 2 to effectively withstand the downward pressure on the mobile base 3. The side pressure guide wheel 3042 is located at the bottom of the mounting plate and rolls against the side of the slide rail 2 to effectively withstand the horizontal push and pull forces on the mobile base 3, ensuring that the mobile base 3 can move stably on the slide rail 2.

[0019] A telescopic sleeve 4 is vertically fixedly connected to the middle of the crossbeam 303, and the telescopic sleeve 4 includes a fixed sleeve 401. The lower end of the fixed sleeve 401 is fixedly connected to the crossbeam 303, and a telescopic sleeve 402 is slidably connected to the middle of the upper end. The upper end of the telescopic sleeve 402 is fixedly connected to a top mounting block 403. A hydraulic cylinder 14 is installed in the middle of the fixed sleeve 401 and the telescopic sleeve 402. The lower end of the hydraulic cylinder 14 is fixedly connected to the fixed sleeve 401, and the upper end is pressed against the end of the telescopic sleeve 402. The hydraulic cylinder 14 is connected to the hydraulic pump 13 through a hydraulic oil pipeline. The hydraulic pump 13 controls the hydraulic cylinder 14 to drive the telescopic sleeve 402 to rise and fall, thereby realizing the extension and retraction of the telescopic sleeve 4. The hydraulic pump 13 is fixedly installed on the extension plate 305 fixedly connected to the end of the crossbeam 303. The middle part of the fixed sleeve 401 is rotatably sleeved with a lower rotating seat 5, and the side of the lower rotating seat 5 is fixedly connected to a top pressure pad 501, and the upper end of the fixed sleeve 401 is installed with an upper rotating seat 6, and the telescopic sleeve 402 rotatably cooperates with the upper rotating seat 6, and the two sides of the upper rotating seat 6 are rotatably connected to the oblique support rod 11 through the rotating shaft, and the top mounting block 403 is rotatably mounted with a lifting and flipping frame 7 through a pin shaft, and the lifting and flipping frame 7 can be vertically rotated around the pin shaft. When the lifting and flipping frame 7 is in a vertical state, its lower end rests on the top pressure pad 501, and the lifting and flipping frame 7 can be horizontally rotated on the telescopic sleeve 4 with the telescopic sleeve 402 through the upper rotating seat 6 and the lower rotating seat 5. During the rotation, the telescopic sleeve 402 rotates in the fixed sleeve 401, and the hydraulic cylinder 14 does not rotate.

[0020] A damper locking rod 9 is rotatably connected to the middle of the lifting and flipping frame 7. A damper 8 is rotatably mounted on the middle of the damper locking rod 9. The damper 8 is located in the middle of the lifting and flipping frame 7. The lower end of the lifting and flipping frame 7 is fixedly connected to a support plate 701, making the entire frame L-shaped. When the lifting and flipping frame 7 is in a vertical position, the support plate 701 is in a horizontal position, which facilitates its insertion under the wooden pallet 10 that comes with the piano during transportation. Slots 702 are provided on both sides of the lifting and flipping frame 7 below the top mounting block 403. Top pressure columns 801 are fixedly connected to both sides of the outer shell of the damper 8. Top pressure locking blocks 901 are fixedly connected to the damper locking rod 9. The top pressure locking blocks 901 are located on both sides of the damper 8 and correspond to the top pressure columns 801. When the telescopic sleeve 4 is required to drive the lifting and turning frame 7 to rise, the inclined support rod 11 is not connected to the damper 8, and the pressing locking block 901 presses against the pressing column 801, thereby locking and fixing the damper 8. The end of the damper locking rod 9 is fixedly connected to the locking handle 902. The end of the inclined support rod 11 has a hole. When the hydraulic cylinder 14 drives the telescopic sleeve 4 to extend to a certain length and lifts the lifting and turning frame 7 to a certain height, the damping connecting shaft 12 passes through the long hole 702 and rotates and connects with the damper 8 and the inclined support rod 11 respectively, rotating and connecting the inclined support rod 11 and the damper 8 together. By rotating the damper locking rod 9 through the locking handle 902, the top pressure locking block 901 is disengaged from the top pressure column 801, thereby unlocking the damper 8. At the same time, the hydraulic pump 13 is depressurized so that the hydraulic cylinder 14 and the telescopic sleeve 4 can be retracted, and the lifting and flipping frame 7 can be rotated from the vertical direction to the horizontal direction. During this process, the hydraulic cylinder 14 and the telescopic sleeve 4 are retracted under the action of the piano's own weight, and the diagonal support rod 11 rotates under the damping support of the damper 8.

[0021] The working principle of the present invention is as follows: during use, first loosen the locking nut 308, lower the movable base plate 301 and the telescopic legs 306, and make the rollers 302 contact the ground. Then tighten the locking nut 308 to fix the telescopic legs 306 and the leg sleeves 307, push the movable base 3 to the side of the cart body 1, so that the lifting and turning frame 7 is extended to the outside of the cart body 1, loosen the pressure relief valve on the hydraulic pump 13 to make the telescopic sleeve 4 in a retracted state, and put the lifting and turning frame 7 in the lowest position. Insert the support plate 701 under the wooden pallet 10 that comes with the piano when it is transported, and use the binding belt to tie the piano and the wooden pallet 10 to fix them on the lifting and turning frame 7. Then, tighten the pressure relief valve on the hydraulic pump 13 to activate it. The hydraulic cylinder 14 pushes the telescopic sleeve 402 upward, raising the lifting frame 7 and the piano to the top of the cart body 1. Then, retract the movable base 3 and release the pressure relief valve on the hydraulic pump 13 to retract the hydraulic cylinder 14 and the telescopic sleeve 4, lowering the wooden pallet 10 and the piano onto the cart body 1. Then, loosen the locking nut 308, raise the movable base 301 and the telescopic legs 306, and lift the rollers 302 off the ground. Then, tighten the locking nut 308 to secure the telescopic legs 306 and the leg sleeve 307, and push the cart body 1 to move the piano. When the piano needs to be placed and the piano angle needs to be adjusted, the piano can be pushed directly so that the piano can be horizontally rotated around the telescopic sleeve 4 along with the lifting and flipping frame 7 under the support of the upper rotating seat 6 and the lower rotating seat 5, thereby adjusting the position of the piano. Then, the piston rod of the telescopic sleeve 4 is extended by the hydraulic pump 13, so that the lifting and flipping frame 7 and the piano are lifted to a certain height together. Then, the oblique support rod 11 is rotated so that its end hole is aligned with the long hole 702. Then, the damping connecting shaft 12 is passed through the long hole 702 accordingly, and is respectively rotated and connected with the damper 8 and the oblique support rod 11. The oblique support rod 11 is rotated and connected with the damper 8. Together, and the hydraulic pump 13 is depressurized to allow the telescopic sleeve 4 to contract, the lifting and flipping frame 7 can be rotated to rotate around the rotating shaft at the end of the piston rod of the telescopic sleeve 4, and rotate from the vertical direction to the horizontal direction. During this process, the telescopic rod of the telescopic sleeve 4 slowly contracts under the pressure of the piano's own weight. At the same time, the oblique support rod 11 rotates around the damping connecting shaft 12 under the damping support of the damper 8, and slides in the long hole 702, thereby forming a damping support for the lifting and flipping frame 7 and flipping it to a horizontal position. By flipping the piano to an upright position, the piano legs can support the ground for unloading, completing the lifting, transfer, and flipping of the piano.
