DETAILED DESCRIPTION

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a movable safety device for loading and unloading materials, such as Figure 1-4 As shown, the movable safety device for loading and unloading materials includes: a base 1; a movable wheel 2 installed at the bottom of the base 1; a first electric hydraulic rod 3 fixedly installed on the top of the base 1 for adjusting the height; a retractable adjustment plate 4 arranged on the first electric hydraulic rod 3; and a hanging ring 5 arranged on the adjustment plate 4 for hanging a safety belt.

[0023] It should be noted that, since the height and width of the existing device are fixed and cannot be adjusted, and the height and width of the vehicles currently transporting tobacco materials are different, the existing movable loading and unloading safety devices cannot adapt to vehicles of different sizes in some cases, thus affecting the efficiency and safety of loading and unloading. Vehicle size differences: Different tobacco transport vehicles have different heights and widths. If the height and width of the movable loading and unloading safety device are fixed, then when facing vehicles of different sizes, it may be necessary to readjust the height and width of the device, which will increase the complexity and time cost of the operation; Reduced loading and unloading efficiency: Due to differences in vehicle size, fixed-height devices may not be aligned with the optimal loading and unloading points of the vehicle, which may result in reduced loading and unloading efficiency. For example, if the height of the device is too high, it may take extra time and effort to lift the materials to the height of the device; conversely, if the height of the device is too low, it may take extra time and effort to remove the materials from the device; Increased safety hazards: If the height and width of the device cannot be adjusted, there may be some safety hazards. For example, if the height of the device does not match the height of the vehicle, there may be unstable operations during the loading and unloading of materials, increasing operational risks;

[0024] In this embodiment, a universal moving wheel 2 is installed on the base 1 so that personnel can push the device to a suitable position, and the first electric hydraulic rod 3 is set to adjust the height of the adjustment plate 4 according to the height of the vehicle when started to adapt to vehicles of different heights. The set adjustment plate 4 can be adjusted laterally to adapt to vehicles of different widths. The set hanging ring 5 allows personnel who load and unload materials to hook the rope hook of the safety belt on the hanging ring 5 to avoid pulling effect and prevent personnel from falling from the truck, which is conducive to safe loading and unloading of materials.

[0025] In a further preferred embodiment of the utility model, the adjustment plate 4 includes: an assembly plate 6 fixedly mounted on the top end of the output rod of the first electric hydraulic rod 3; a slide plate 7 fixedly mounted on one end of the assembly plate 6; and a sleeve plate 8 slidably mounted on the slide plate 7.

[0027] In a further preferred embodiment of the utility model, an electric adjustment mechanism for adjusting the spacing is provided on the assembly plate 6 and the sleeve plate 8, and the electric adjustment mechanism includes: a motor 9 mounted on the top of the sleeve plate 8; a screw 10 arranged on the output shaft of the motor 9; a limit block 11 fixedly mounted on one end of the screw 10; and a connecting frame 12 threadedly sleeved on the screw 10, and the bottom end of the connecting frame 12 is fixedly connected to the top of the assembly plate 6.

[0028] In this embodiment, the operation of the motor 9 can drive the screw 10 to rotate, the rotating screw 10 will drive the connecting frame 12 to move, and the running connecting frame 12 will drive the assembly plate 6 to move away from the sleeve plate 8, thereby saving effort in adjusting the spacing.

[0029] In a further preferred embodiment of the utility model, a limiting mechanism for limiting position is provided on the base 1, and the limiting mechanism includes: a mounting plate 13 arranged on one side of the base 1; a second electric hydraulic rod 14 mounted on the bottom of the mounting plate 13; and a limiting plate 15 fixedly installed on the top end of the output rod of the second electric hydraulic rod 14.

[0030] In this embodiment, after the device is moved to the specified position, the personnel can start the second electric hydraulic rod 14. The output rod of the running second electric hydraulic rod 14 will extend, which will drive the limit plate 15 to move downward. The bottom of the limit plate 15 will fit with the ground, which can increase friction and play a limiting role, thereby preventing the device from moving without reason, which is beneficial to safety.

[0031] In a further preferred embodiment of the utility model, the bottom of the assembly plate 6 and the sleeve plate 8 are fixedly mounted with a mounting block 16, a bolt rod 17 is threadedly mounted on the mounting block 16, and a sleeve block 18 for assembling the hanging ring 5 is slidably mounted on the bolt rod 17.

[0032] In this embodiment, the mounting block 16 can be equipped with a bolt rod 17, and the sleeve block 18 is slidably mounted on the bolt rod 17. As the person moves, the sleeve block 18 will slide along the bolt rod 17 and can move horizontally to adaptively adjust the position of the hanging ring 5.

[0037] To sum up, the technical solution is operated by the first electric hydraulic rod 3, and the height of the adjustment plate 4 can be adjusted according to the height of the vehicle to adapt to vehicles of different heights. The adjustment plate 4 can be adjusted laterally to adapt to vehicles of different widths, which solves the problem that the height and width of the existing movable safety device for loading and unloading materials are fixed and cannot be adjusted, and cannot adapt to vehicles of different sizes. The hanging ring 5 is set, and the personnel who load and unload materials can hook the rope hook of the safety belt on the hanging ring 5 to avoid the pulling effect and prevent people from falling from the truck, which is conducive to safe loading and unloading of materials.
