Triangular table type frame transport vehicle

Abstract

The invention belongs to the technical field of structural design of manually propelled transport trolleys, and particularly relates to a triangular table type frame transport vehicle. The triangulartable type frame transport vehicle comprises a frame, a telescopic frame and a support frame, wherein the frame comprises two parallel rectangular pipes arranged at the bottom and two positioning rodsarranged at the rear ends of the rectangular pipes; rollers are arranged at the bottom of the frame; a connecting shaft hole is formed in the middle of each telescopic rod; and the support frame comprises a support plate, a front connecting shaft and a rear connecting shaft, the two ends of the front connecting shaft are inserted into the connecting shaft holes, the two ends of the rear connecting shaft are bridged in positioning grooves on the two positioning rods, and the front end and the rear end of the support plate are provided with through holes so that the through holes can respectively sleeve the front connecting shaft and the rear connecting shaft. The triangular table type frame transport vehicle not only can be used as a horizontal trolley, but also can be used as a special triangular trolley, has the same characteristics of being simple in structure and convenient to use as the transport trolley, and carries out adaptability improvement aiming at transportation of displayframe structures, multiple purposes of the trolley is realized and the number of the required transport vehicles is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of structural design of a human-propelled transport trolley, and in particular relates to a triangular platform frame transport trolley. Background technique [0002] On various types of large-scale display screens and other equipment, it is often necessary to install multiple supporting or fixed structural parts such as frames and table frames of different sizes or structures. In the process of production, storage or transfer, desktop transport vehicles are often used, but Due to the different materials and sizes, there are many disadvantages in the actual use process. First, when the vertical trolley is used for packing, the outer frame is downward. Since the center of gravity directly acts on the frame body vertically downward, the truck vibrates during transportation. It is easy to cause the structure such as the flange of the inner frame to shift to one side, and the structure such as the frame is separ...

Problems solved by technology

[0002]In various types of large-scale display screens and other equipment, it is often necessary to install multiple supporting or fixed structural parts such as frames and table frames of different sizes or structures. In the process of storage or transfer, desktop transport vehicles are often used, but due to the different materials and sizes, there are many disadvantages in the actual use process. First, the outer frame is downward when using a vertical trolley. Directly acting on the frame body vertically downward, the vibration of the truck during transportation may easily cause the structure such as the flange of the inner frame to shift to one side, and the structure such as the frame will be separated back and forth when installed, and the product will be scrapped; for some large frame mechanisms, loading and unloading In the process of vertical box cargo trolley, 5-6 people are required to lift it out, and then use the crane to lift it. In this process, because the product is relatively heavy, when the center of gravity is too high and unstable when standing up, it is easy to cause safety accidents; when loading and unloading, the general matching The height or front and rear dimensions of the transport vehicle are generally fixed. For products with a large size, it is easy to cause suspension deformation on both sides or front and rear sides, and for products with a small size, it will cause uneven force around the product.
