Description

Technical Field

[0001] The utility model relates to an oil rod rising structure of a low-radiation carrier truck, belonging to the technical field of low-radiation carrier trucks. Background Art

[0002] A low-radiation carrier truck is a manual handling device commonly used in logistics, warehousing and manufacturing industries, mainly used for handling and short-distance transportation of goods. Its main feature is that it can place goods at a relatively low height, which makes it very useful in loading and unloading low containers or loading and unloading operations that need to be carried out at a low position.

[0003] Chinese Patent Publication (Publication No.: CN 220926185 U) discloses a low-radiation carrier truck with a piston rod limiting structure, which relates to the technical field of carrier trucks. The technical problem to be solved is to provide a low-radiation carrier truck with a piston rod limiting structure. The adopted solution is as follows: the first rollers are arranged at the bottom end of the base, the first connecting plate is welded at the top end of the base, the lifting plate is slidably connected to the side end of the first connecting plate, the output end of the hydraulic cylinder is connected to the lifting plate through the piston rod, the supporting devices are symmetrically arranged at the bottom side end of the base, the second connecting plate is arranged at the side end of the lifting plate, the third connecting plate is welded to the side end of the second connecting plate, the L-shaped plate is welded to the side end of the third connecting plate, and the bottom end of the L-shaped plate is connected to the second roller through fasteners. The utility model can lift the lifting plate through the hydraulic cylinder and the piston rod, and the lifting plate can lift the goods. In this process, the low-radiation carrier truck can also fix its position through the supporting device, and the low-radiation carrier truck can carry the goods more stably;

[0004] However, the above technology may only adjust the lifting plate through the hydraulic cylinder on one side when performing ascending handling. However, when handling some heavy goods, the ascending speed is slow, which is not convenient for the staff to operate. When lifting the lifting plate, it is necessary to manually increase the pressure to lift the lifting plate. However, when the goods are heavy, it is not convenient for the staff to operate.

[0005] Therefore, an oil rod rising structure of a low-radiation carrier truck is proposed. Summary of the Utility Model

[0006] In view of this, the utility model provides an oil rod rising structure of a low-radiation carrier truck to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0012] Further preferably, the number of the lifting mechanisms is four and they are evenly distributed around the top of the moving plate.

[0013] Further preferably, a sliding groove is formed in the top of the moving plate, and the top of the fixed block is slidably connected to the inside of the sliding groove.

[0014] Due to the adoption of the above technical solutions in the embodiments of the utility model, it has the following advantages:

[0015] First, through the lifting mechanism of the utility model, when adjusting the height of the lifting plate, the screw rod is driven to rotate by the servo motor, the screw rod drives the fixed block to move, the fixed block pushes the inclined rod to move upward, and the lifting plate moves upward, increasing the automation of the device and facilitating the use by personnel.

[0027] Embodiment 1

[0028] As Figures 1-5 shown, the embodiment of the present utility model provides an oil rod lifting structure for a low-level handling truck, which includes a moving plate 1. A lifting plate 2 is movably connected inside the moving plate 1. A lifting mechanism 3 is arranged on the top of the moving plate 1. The lifting mechanism includes a servo motor 301, a screw rod 302, a fixed block 303, a connecting block 304 and an inclined rod 305. The top of the moving plate 1 is fixedly connected to the top of the servo motor 301. The left side of the servo motor 301 is fixedly connected to the right side of the screw rod 302. The surface of the screw rod 302 is sleeved with a fixed block 303. The top of the fixed block 303 is movably connected to the top of the inclined rod 305 through a rotating shaft. One side of the inclined rod 305 away from the fixed block 303 is movably connected to the bottom of the connecting block 304 through a rotating shaft. The top of the connecting block 304 is fixedly connected to the top of the lifting plate 2. A limiting ring 4 is fixedly connected to the front side of the lifting plate 2. The limiting ring 4 is sleeved on the surface of the screw rod 302. Moving wheels 5 are arranged at the bottom of the moving plate 1. The number of the moving wheels 5 is four and they are evenly distributed at the bottom of the moving plate 1. A sliding groove 8 is opened on the top of the moving plate 1. The top of the fixed block 303 is slidably connected inside the sliding groove 8.

[0029] Through the lifting mechanism 3, when adjusting the height of the lifting plate 2, the screw rod 302 is driven to rotate by the servo motor 301. The screw rod 302 drives the fixed block 303 to move. The fixed block 303 pushes the inclined rod 305 to move upward, so that the lifting plate 2 moves upward, increasing the automation of the device and facilitating the use by personnel. By setting the limiting ring 4, the moving direction of the fixed block 303 can be restricted to ensure the normal use of the structure.

[0030] Embodiment 2

[0031] In one embodiment, a push handle 6 is fixedly connected to the top of the moving plate 1. A pushing mechanism 7 is arranged on the top of the moving plate 1. The pushing mechanism 7 includes a fixed frame 701, a telescopic cylinder 702 and a telescopic rod 703. The bottom of the fixed frame 701 is fixedly connected to the top of the moving plate 1. The bottom of the fixed frame 701 is fixedly connected to the top of the telescopic cylinder 702. The bottom of the telescopic cylinder 702 is fixedly connected to the top of the telescopic rod 703. The bottom of the telescopic rod 703 is fixedly connected to the top of the lifting plate 2. The number of the lifting mechanisms 3 is four and they are evenly distributed around the top of the moving plate 1.

[0032] Through the pushing mechanism 7, when the lifting plate 2 is lifted and lowered, the telescopic cylinder 702 is used to assist in lifting and lowering the lifting plate 2. If the whole device is damaged, by setting the sliding groove 8, when the fixed block 303 moves, its direction and stroke can be restricted to ensure the normal use of the whole device.

[0033] When the utility model works: after pushing the moving plate 1 to the top of the object to be carried, start four servo motors 301 simultaneously. The servo motors 301 drive the screw rods 302 to rotate. Through the engagement between the surface of the screw rods 302 and the inner sides of the fixed blocks 303, the fixed blocks 303 push the inclined rods 305 to rotate, and the inclined rods 305 push the connecting blocks 304 to move upward, pushing the lifting plate 2 to move upward to lift the goods. While rising, the telescopic cylinder 702 contracts the telescopic rod 703 to accelerate the rising speed. Pull the push handle 6 to facilitate the staff to move the moving plate 1. When it is carried to the designated position, start the motor in the reverse direction, and the lifting plate 2 can be moved downward to facilitate the staff to use.
