Description

Technical Field

[0001] The utility model relates to the technical field of material handling, in particular to a material handling platform. Background Art

[0002] The handling platform is a common cargo handling tool in current logistics companies and construction processes, and its purpose is to conveniently load and unload the goods on the truck.

[0003] After retrieval, a Chinese patent with the publication number of CN202121820745.4 discloses a lifting handling platform device with an adjustable handling surface. By setting a fixed table board and a sliding table board that slide relative to each other, it is convenient to adjust the load-bearing range of the material. By setting a rotating support leg mechanism, cooperating with the mobile wheels and rollers, it is convenient to move and stabilize the utility model. By setting a fixed table board equipped with a lifting plate, cooperating with a jack and a chain, one person can easily complete the loading and unloading, thereby reducing the construction cost and improving the material handling efficiency.

[0004] The above technical solution has the following defects. Although such a material handling platform can be adjusted in height by a jack, the staff can carry the material onto the handling platform, and the handling platform can adjust its height for material unloading or loading. However, in the actual use process, the staff needs to move back and forth between the carriage and the top of the unloading platform for handling, which is relatively laborious. To further improve the handling efficiency and reduce the manual consumption, a material handling platform is now proposed. It can not only drive the platform lifting frame to adjust the height through a hydraulic cylinder, but also be provided with a protruding component, which can transmit the handling platform into the carriage, so as to facilitate the loading and unloading of materials in the carriage. During the handling process, the position of the material can be adjusted, so that after a row of materials is stacked, the position can be adjusted, enabling the staff to continuously stack the materials at the port, thereby reducing the handling distance. After the materials are loaded, they can be lowered to the ground, facilitating the staff to unload the materials at a low height, making the material handling process more convenient.

[0005] In view of this, this creation improves and solves the above problems, conducts intensive research and combines with the application of theory, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background art section is only intended to deepen the understanding of the overall background art of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art. Summary of the Utility Model

[0007] The utility model provides a material loading and unloading platform, which solves the problems raised in the above background. It can not only drive the platform lifting frame to adjust the height through a hydraulic cylinder, but also be provided with a protruding component, which can transmit the loading and unloading platform into the carriage, so as to facilitate the loading and unloading of materials in the carriage. During the loading and unloading process, the position of the materials can be adjusted, so that the position can be adjusted after a row of materials is stacked, enabling the staff to continuously stack the materials at the port, thereby reducing the handling distance. After the materials are loaded, they can be lowered to the ground, facilitating the staff to unload the goods at a low height, making the material loading and unloading process more convenient.

[0008] The solution of the utility model to the above technical problems is as follows: A material loading and unloading platform, including a load-bearing base and a load-bearing bracket. A lifting bracket is fixedly installed at the top of the load-bearing base. There are two lifting brackets, and hydraulic cylinders are fixedly installed on both of the two lifting brackets. The hydraulic cylinders are fixedly installed with a lifting support plate, and the lifting support plate is fixedly connected with the load-bearing bracket. A brake stepping motor is installed on the load-bearing bracket, and the brake stepping motor is fixedly connected with a ball screw. The outer wall of the ball screw is threadedly connected with a screw nut. Both sides of the screw nut are fixedly connected with load-bearing sliders. A load-bearing rod is fixedly installed on the inner wall of the load-bearing bracket. The top of the load-bearing slider is fixedly installed with a material platform, and a conveyor belt is arranged in the material platform.

[0009] On the basis of the above technical solution, the utility model can be further improved as follows.

[0010] Further, a frame-shaped through hole is opened at the top of the load-bearing base corresponding to the load-bearing bracket, so that the load-bearing bracket can be received into the load-bearing base, thereby facilitating the staff to load and unload goods when the load-bearing bracket is lowered.

[0011] Further, a threaded cylinder is fixedly installed on the load-bearing base, and a positioning screw rod is threadedly connected to the threaded cylinder. The positioning screw rod is rotatably connected with a positioning base. Rotating the positioning screw rod in the threaded cylinder can drive the positioning base to lift and lower. The positioning base presses against the ground, so that the platform can be stably placed on the ground for material loading and unloading.

[0012] Further, limit sliders are fixedly installed at both ends of the lifting support plate, and limit grooves are opened on the inner wall of the lifting bracket corresponding to the limit sliders. The limit sliders slide in the limit grooves, so that the lifting support plate can stably lift and lower in the lifting bracket.

[0013] Further, auxiliary pulleys are fixedly installed on the limit sliders, so that the lifting support plate can stably lift and lower in the lifting bracket.

[0014] Further, the ball screw is rotatably connected to the inner wall of the load-bearing bracket, so that the ball screw can stably rotate on the inner wall of the load-bearing bracket.

[0015] Further, a sliding hole is provided in the load-bearing slider corresponding to the load-bearing rod, and the inner wall of the sliding hole is slidably connected to the load-bearing rod, so that the load-bearing rod can limit and bear the load of the load-bearing slider.

[0016] Further, a moving wheel is fixedly installed at the bottom of the load-bearing base, so that the loading and unloading platform is convenient to move.

[0017] The utility model provides a material loading and unloading platform, which has the following advantages:

[0018] 1. The moving wheel can drive the loading and unloading platform to move. After moving to the transport vehicle, the positioning screw rod can be rotated. The positioning screw rod can drive the positioning base to press down to position the loading and unloading platform, so that the loading and unloading platform is convenient to move to the required position for use;

[0019] 2. By synchronously starting multiple hydraulic cylinders through the same hydraulic component, the hydraulic cylinders can drive the lifting support plate to lift and lower in the lifting bracket, so that the load-bearing bracket can be adjusted in height. After the material platform is adjusted to the height of the carriage, the brake stepping motor rotates the ball screw to drive the material platform to slide from the top of the load-bearing bracket into the carriage. The staff can load the material onto the conveyor belt of the material platform, so that the material can be loaded and unloaded in the carriage, making the loading and unloading process more convenient;

[0020] 3. After a row of materials is stacked, the conveyor belt can be started to drive the materials to move, so that the staff only needs to carry the materials to the end of the material platform for stacking. After stacking, the brake stepping motor can be started to reverse to drive the material platform to retract into the load-bearing bracket, and the hydraulic cylinder can be started to drive the load-bearing bracket to lower, and the staff can unload the materials at a low place;

[0021] 4. Such a material loading and unloading platform can not only adjust the height of the platform lifting frame through the hydraulic cylinder, but also be provided with a protruding component, which can transmit the loading and unloading platform into the carriage, so as to facilitate the loading and unloading of materials in the carriage. During the loading and unloading process, the position of the materials can be adjusted, so that the position can be adjusted after a row of materials is stacked, so that the staff can continuously stack the materials at the port, thereby reducing the handling distance. After the materials are loaded, the materials can be lowered to the ground, which is convenient for the staff to unload the materials at a low height, making the material loading and unloading process more convenient.
