Loading and unloading transport vehicle

Abstract

The invention discloses a loading and unloading transport vehicle. The transport vehicle comprises two first lifting rods, two second lifting rods, a clamping mechanism, a driving mechanism and a controller, wherein the two first lifting rods are arranged left and right respectively; the two second lifting rods are hinged with the middle parts of the corresponding first lifting rods respectively;the driving mechanism is used for driving the clamping mechanism to ascend and descend; the clamping mechanism also comprises a chassis bracket, a guide groove bracket, three clamping rods and a driving source; the chassis bracket is connected with the power output end of the driving mechanism; the guide groove bracket is arranged on the chassis bracket and can be ascended and descended along with the chassis bracket; the three clamping rods are movably arranged on the guide groove bracket and are perpendicular to the end face of the guide groove bracket; and the driving source is used for driving the clamping rods to move back and forth. Compared with the prior art, the transport vehicle has the advantages that: the three adjustable clamping rods are used for realizing clamping, so the clamping is firm; and because the gap among the clamping rods is adjustable, coiled objects with different diameters can be transported without clamp holders of various specifications, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to a handling device. In particular, it relates to a conveying device that can be applied to roll objects, and can be widely used in industries such as tapes, films, and papermaking. Background technique [0002] In the tape, film, papermaking and other industries, it is often necessary to carry roll-shaped objects placed in an upright or flat state, such as paper rolls, film rolls and other materials, generally three methods are used. [0003] The first is to put these rolled objects on a pallet, and then use a forklift to fork them from one place to another. This method is simple and easy to implement, and has been widely used, but it also has many shortcomings. Rolled objects must be placed on a pallet to be transported by a forklift, which requires the production of many pallets, which requires a large production investment and does not meet the low-carbon requirements; secondly, many pallets seem to take up space when used; ...

Problems solved by technology

[0003] The first is to put these rolled objects on a pallet, and then use a forklift to fork them from one place to another. This method is simple and easy to implement, and has been widely used, but it also has many shortcomings. Rolled objects must be placed on a pallet to be transported by a forklift, which requires the production of many pallets, which requires a large production investment and does not meet the low-carbon requirements; secondly, many pallets seem to take up space when used; In the case of small and high height, it is unsafe to place the roll-shaped objects on the pallet and then use the forklift

[0004] The second is to use a two-wheeled trolley for transportation. This method of transportation requires manpower to transport the rolled objects to the trolley. If the rolled objects are heavy, more than two people are required to cooperate with the operation, and the work intensity is high. , and the work efficiency is low

[0005] The third is to use a clamp-type handling tool, such as the Chinese utility model patent "A Forklift Attachment Barrel Holder" (authorized announcement number: CN2295732Y) whose patent number is ZL97217555.5. You can also refer to the patent number as ZL200820057573.8 The Chinese utility model patent "forklift oil drum clamping device" (authorized announcement number: CN201195683Y), but this kind of handling tool is not good for rolling objects that are prone to slipping between layers, such as handling release film rolls, The clamp is stressed on the outer side of the release film roll. When clamping and lifting, there will be slippage between the outer film and the inner film, which is easy to damage the content of the release film roll. In addition, for roll objects with different diameters, special Suitable grippers are matched, which will inevitably increase the handling cost

[0007] However, the above-mentioned disclosed handling device is more suitable for barrel-shaped objects with raised edges, but because roll-shaped objects do not have edges that can be clamped, they are powerless
