[0002] The carrier is a logistics carrier equipment for carrying goods. When the manual pallet carrier is used in a carrying station, the fork carried by the manual pallet carrier is inserted into the pallet hole, the hydraulic system is driven by manpower to realize the lifting and lowering of the pallet goods, and the carrying operation is completed by manpower. It is the most simple, effective and common loading, unloading and carrying tool in the pallet transport tool of the carrying station.
[0003] At present, the lifting structure of the carrier is poor in stability when carrying goods, lacks effective support and limiting design in the lifting process, and is easy to shake, which not only affects the safety of the goods, but also may cause damage to the goods. In addition, when the goods are lifted, there is no good buffer mechanism, so that the goods are easy to be damaged by impact force, and the service life of the carrier itself is also affected. SUMMARY
[0004] The utility model aims at providing a carrier with lifting mechanism to solve the problems in the above background technology.

[0006] Preferably, the inside of the driven worm wheel is provided with thread in the through hole, so that the lifting lead screw can be driven to move up and down.
[0007] Preferably, the driving part includes sliding support frame, the outer wall of the limiting rack is slidably provided with sliding support frame, and the inside of the sliding support frame is rotatably provided with driving gear.
[0008] Preferably, the driven part includes support rotating branch, one end of the lifting support plate is fixed with support rotating branch, the inside of the support rotating branch is formed with through hole, the through hole is rotatably provided with driven rotating rod, one end of the driven rotating rod is fixed on one side of the driving gear, one side of the driven rotating rod is fixedly provided with driving worm, and one side of the driving worm is engaged with the driven worm wheel.
[0009] Preferably, an arc-shaped thread matching the outer wall of the driven turbine is provided on the outer wall of the driving worm, so as to drive the driven turbine to rotate.
[0010] Preferably, the buffer member includes a limiting horizontal plate. The bottom outer wall of the lifting screw rod is fixed with a limiting horizontal plate. A slideway is formed inside the bottom end of the lifting screw rod. A sliding support rod slides in the slideway. The bottom end of the sliding support rod is fixed with a stable base. Springs are fixed inside the limiting horizontal plate and the stable base.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] The sliding support frame in the driving member supports the driving gear. Under the limitation of the limiting rack, the driving gear is driven to rotate, and then the driving worm is driven to rotate through the driven rotating rod. The meshing design of the driving worm and the driven turbine uses the arc-shaped thread matching its outer wall to drive the driven turbine to rotate. The thread inside the driven turbine cooperates with the lifting screw rod, thereby driving the buffer member to move up and down.
[0013] The supporting rotating rod at one end of the lifting support plate supports the driven rotating rod through the internal through hole, ensuring the smoothness of the transmission process. The supporting turbine horizontal plate supports the driven turbine, and at the same time, the internal through hole limits the moving stroke of the lifting screw rod, making the entire lifting structure more stable and ensuring the safety of the goods during the lifting process.
[0014] The limiting horizontal plate in the buffer member limits the spring. When the lifting screw rod descends, it buffers the lifting screw rod through itself and the spring. The sliding support rod supports the stable base. The spring between the stable base and the limiting horizontal plate uses its own elastic force to buffer the impact force during the lifting and lowering process of the lifting screw rod, avoiding damage to the goods due to collision.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 This utility model provides a technical solution: a transport vehicle with a lifting mechanism, including a transport vehicle 1 and a lifting support plate 2. A limiting rack 3 is fixed to one side of the transport vehicle 1. The limiting rack 3 limits the travel of the sliding support frame 4 and can drive the drive gear 5 to rotate. A driving component slides on the outer wall of the limiting rack 3. A driven component is fixed to one side of the lifting support plate 2. A vortex cross plate 9 is fixed to one end of the lifting support plate 2. The vortex cross plate 9 supports the driven worm gear 10 and limits the travel of the lifting screw 11 through an internal through hole. The top of the vortex plate 9 has a driven turbine 10 that rotates. The driven turbine 10 can drive the lifting screw 11 to move up and down by driving the worm gear 8 and the thread provided on the inner wall. The driven turbine 10 has a through hole inside, and the lifting screw 11 is threaded inside the through hole. The lifting screw 11 is installed inside the vortex plate 9. The lifting screw 11 moves downward and is supported by the lifting support plate 2 by the buffer. The bottom end of the lifting screw 11 is fixed with a buffer. The driven turbine 10 has a thread in the through hole inside, which can drive the lifting screw 11 to move up and down.
[0023] The driving component includes a sliding support frame 4, which slides on the outer wall of the limiting rack 3. The sliding support frame 4 supports the driving gear 5 and drives the driving gear 5 to rotate through the limiting rack 3. The driving gear 5 rotates inside the sliding support frame 4 and drives the driven rod 7 to rotate through the limiting rack 3.
[0024] The driven component includes a support rod 6. One end of the lifting support plate 2 is fixed with the support rod 6. The support rod 6 supports the driven rod 7 through an internal through hole. The support rod 6 has an internal through hole, in which the driven rod 7 rotates. One end of the driven rod 7 is fixed to one side of the drive gear 5. The driven rod 7 drives the drive worm 8 to rotate through the drive gear 5. The drive worm 8 is fixed to one side of the outer wall of the driven rod 7, and a driven turbine 10 is meshed on one side of the drive worm 8. The drive worm 8 drives the driven turbine 10 to rotate through the arc-shaped thread on its outer wall. The outer wall of the drive worm 8 is provided with an arc-shaped thread that matches the outer wall of the driven turbine 10, thereby enabling the driven turbine 10 to rotate.
[0025] The buffer includes a limiting plate 12. The limiting plate 12 is fixed to the outer wall of the bottom end of the lifting screw 11. The limiting plate 12 limits the spring 15 and buffers the lifting screw 11. A slide is formed inside the bottom end of the lifting screw 11. A sliding support rod 13 slides in the slide and supports the stable base 14. The bottom end of the sliding support rod 13 is fixed to the stable base 14. The stable base 14 buffers the lifting screw 11 through the spring 15 and the limiting plate 12. The limiting plate 12 and the stable base 14 are fixed with spring 15 inside. The spring 15 buffers the limiting plate 12 through its own elasticity and the stable base 14.
[0026] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0027] The user lifts the material using the lifting support plate 2. The lifting support plate 2 moves upward, which in turn drives the driven rotating rod 7 upward via the rotating support rod 6. The driven rotating rod 7 drives the sliding support frame 4 upward, which in turn drives the drive gear 5 upward. The drive gear 5, moving upward, is limited by the limiting rack 3, causing it to rotate along its own axis. The drive gear 5 then drives the driven rotating rod 7 to rotate, which in turn drives the drive worm gear 8 to rotate. The rotation of the driven worm gear 8, through the arc-shaped thread on its outer wall and the arc-shaped thread on the outer wall of the driven turbine 10, drives the driven worm gear 10 to rotate. The driven turbine 10 rotates around its own axis. When the driven turbine 10 rotates around its own axis, the rotation of the driven turbine 10 is converted into the vertical linear motion of the lifting screw 11 through its internal thread. The lifting screw 11 drives the limiting horizontal plate 12 and the sliding support rod 13 to move downward. The sliding support rod 13 drives the stabilizing base 14 to move downward and fit against the ground. The stabilizing base 14 fits against the ground and the lifting screw 11 is buffered by the spring 15 and the limiting horizontal plate 12, thereby preventing the material from tilting on the lifting support plate 2 and causing the transport vehicle 1 to tip over.
