Description

Technical Field

[0001] The utility model belongs to the technical field of metal material processing, and particularly relates to a lifting tool convenient for unloading materials. Background Art

[0002] Lifting tools can quickly and accurately connect and lift goods. Especially in the logistics, warehousing, and transportation industries, they can significantly improve the loading and unloading efficiency and reduce labor costs. For example, at construction sites, lifting tools can be used to carry and hoist heavy building materials such as steel bars and concrete to help construct buildings. At the same time, lifting tools are also commonly used in high-altitude operations, such as hanging scaffolding on the exterior walls of buildings and installing glass curtain walls:

[0003] Existing equipment only simply lifts and takes goods during use. It is very easy for the goods to fall off during the lifting process, resulting in accidents. At the same time, after the lifting is completed, manual intervention is required to unload the materials. Moreover, when encountering different materials, the lifting tool needs to be replaced to carry out subsequent work. The device is not easy to move, which is very troublesome. Therefore, we have proposed a lifting tool convenient for unloading materials. Summary of the Utility Model

A plurality of pull rods two are rotatably connected to the outer wall of the fixed shaft. A fixed shaft two is fixedly connected to the inner wall of the end of the pull rod two far away from the fixed shaft.

[0007] Through the above technical solution, when the fixed shaft two moves, it will drive the pull rod two to move. When the pull rod two moves, it will drive the pull rod to move through the fixed shaft. The fixed block can limit the position of the pull rod.

[0008] Further, a motor is slidably connected to the inner wall of the motor bracket. The bottom output end of the motor is fixedly connected to a transmission shaft through a coupling. The transmission shaft is rotatably connected to the lifting tool support.

[0009] Through the above technical solution, the rotation of the motor will drive the transmission shaft to rotate, and the rotation of the transmission shaft will drive the threaded rod to rotate.

[0010] Furthermore, a threaded rod is fixedly connected to the outer wall of one end of the transmission shaft away from the motor, a sliding block is rotatably connected to the outer wall of the threaded rod, a hydraulic press is fixedly connected to the bottom of the sliding block, and the hydraulic press is fixedly connected to a fixed block.

[0011] Through the above technical solution, the rotation of the threaded rod will drive the slider to move forward and backward, and the hydraulic press can adjust the overall height of the clamping mechanism to a position suitable for lifting materials.

[0012] Furthermore, the inner wall of the fixed shaft is fixedly connected to the fixed shaft three, the outer wall of the fixed shaft three is rotatably connected to the pull rod three, and the inner wall of the pull rod three is fixedly connected to the fixed shaft four.

[0013] Through the above technical solution, the movement of the fixed shaft four will drive the movement of the pull rod three, and the movement of the pull rod three will drive the movement of the fixed shaft three.

[0014] Furthermore, the outer wall of the fixed shaft 4 is rotatably connected with a clamping plate, the outer wall of the clamping plate is slidably connected with a slide plate, and the outer wall of the slide plate is fixedly connected with a plurality of telescopic rod sleeves.

[0015] Through the above technical solution, when the splint moves, it will pull the telescopic rod sleeve to move, and the telescopic rod sleeve slides on the sliding rod, making the movement process of the splint more stable.

[0016] Furthermore, a sliding rod is fixedly connected to the outer wall of the splint, and the sliding rod is slidably connected to the telescopic rod sleeve. A plurality of springs are fixedly connected to the outer wall of the slide plate, and the springs are fixedly connected to the splint. A plurality of fixed blocks 2 are fixedly connected to the bottom of the slide plate.

[0017] Through the above technical solution, after the material is lifted and taken out, the spring will reset and then the splint will reset.

[0018] Furthermore, the inner wall of the second fixing block is fixedly connected with a plurality of limit shafts, the outer wall of the limit shaft is rotatably connected with a protection hook sleeve, and the inner wall of the protection hook sleeve is fixedly connected with the second limit shaft.

[0019] Through the above technical solution, when the material is being lifted, the protective hook sleeve will press against the rotating hook to form a closed loop to prevent the material from falling off.

[0020] Furthermore, the outer wall of the second limiting shaft is rotatably connected with a rotatable hook, the bottom of the slide plate is fixedly connected with a second spring, the second spring is fixedly connected to the rotatable hook, the bottom of the slide plate is fixedly connected with a third spring, and the third spring is fixedly connected to the protective hook sleeve.

[0021] Through the above technical solution, after the material is taken out, the rotating hook will be pulled by spring two and spring three to complete automatic reset, which is convenient for the next material lifting operation.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model is provided with a sling bracket. When the equipment needs to be used, the sling bracket is pushed as a whole to reach above the material that needs to be lifted, and then the motor is started to adjust the position of the clamping mechanism. The rotation of the motor drives the transmission shaft to rotate to rotate the threaded rod. The rotation of the threaded rod drives the slider to move. The hydraulic press is started to adjust the position of the clamping mechanism, and the material is hung on the rotating hook. Due to the effect of gravity, the rotating hook will pull the protective hook sleeve and move downward at the same time. At this time, the rotating hook will resist the protective hook sleeve to prevent the material from falling off, so that unloading and lifting of materials can be easily achieved without manual operation, saving production costs. At the same time, when encountering materials of different sizes that need to be retrieved, there is no need to replace the sling, saving costs. At the same time, during the lifting process, the material will not fall off and cause material damage.

[0024] 2. The utility model is provided with a rotating hook. When the equipment is in use, the rotating hook moves downward to pull the skateboard, and the skateboard moves downward by pulling the fixed shaft four, and the pull rod three moves downward by pulling the fixed shaft three. The pull rod two moves by the fixed shaft, and the pull rod three moves downward by compressing the spring and making the clamp slide inward, thereby squeezing the material and applying friction to the surface of the material to further clamp the material. Then the hanger bracket can be pushed to move the material. After reaching the position, it only needs to gently put the material on the ground. The rotating hook and the clamp will reset due to not being subject to greater gravity, so that the position of the hanger can be adjusted. When encountering materials of different heights, the height can be adjusted to achieve lifting. At the same time, when the device needs to be moved, the universal wheel can provide convenience and can firmly fix the material in the device, and the material will not rotate easily during the moving process.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
