Description

Turnover type canopy device of freight vehicle

Technical Field

The utility model relates to a convertible canopy device of freight vehicle.

Background

In the process of freight transportation of a freight vehicle, goods in a container need to be covered for various reasons (such as scattering prevention, water prevention, sun protection, wind prevention, radiation protection and the like), in order to save time consumption and facilitate, the existing freight vehicle mostly adopts a mode of arranging a canopy on the container, in order to meet the requirement, various canopy devices are arranged in the prior art, for example, a rotating shaft is adopted to drive a side turning rod to rotate, the side turning rod drives a transverse turning rod to rotate, and the transverse turning rod drives a tarpaulin to cover, so that the structure causes the movement range of the tarpaulin to be greatly reduced, and the only solution is that the rotation range of the side turning rod is enlarged; as shown in chinese patent CN201317309Y, the movement range of the cover plate is reduced, but in practical use, the structure basically exhibits 270 degrees of rotation, and therefore requires a driving motor with very high power, otherwise, the cover plate cannot be covered on the carriage when the cover plate is a whole, in order to solve this problem, the only solution is to divide the cover plate into two parts, but in the case of dividing into two parts, one more driving device is needed, and the situation that the top object cannot be prevented from contacting with the outside inevitably cannot achieve the purpose of effective covering.

Disclosure of Invention

For solving the defect that prior art exists, the utility model provides a convertible canopy device of freight vehicle, it is through setting up a durable chain as the power supply on the carriage, the drive can be folded the apron of folding and realize opening of carrying the packing box, realize the cover to carrying cargo box through making the folded sheet tiling, and the folded sheet is folding back and is only in the front and back both sides in carriage, no matter load and unload or load and unload from the side from the top, all can not influence handling efficiency, and its simple structure, can effectually realize the complete cover to carrying cargo box.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a turnover type canopy device of a freight vehicle comprises a cargo carrying case, wherein the cargo carrying case is enclosed by a long side and a short side, two groups of folding cover plates are arranged at the upper side in the cargo carrying box, one end of each folding cover plate is provided with a rotating shaft, the rotating shaft is rotatably arranged on the short side of the cargo carrying box, the middle part of the long side of the cargo carrying box is provided with a transmission gear, the transmission gear consists of two groups of meshed wheels which are meshed with each other and chain gears which are positioned at the side ends of the meshed wheels, the short sides of the cargo carrying boxes at the two sides of the transmission gear are respectively provided with a first chain gear, one chain gear I is connected with the power driving device, the chain gear is connected with the chain gear I through a transmission chain, the top surface of the transmission chain is fixedly connected with the other end of the folding cover plate, the folding cover plate is folded through forward or reverse movement of the transmission chain, and the cargo box is covered or opened; compared with the prior art, the beneficial effects of the utility model reside in that: because the folding plate is adopted and the transmission chain drives the folding plate to be folded or tiled, the cargo carrying box can be effectively covered; due to the adoption of chain transmission, the durable effect is greatly improved; and set up the meshing drive wheel, therefore, only need a power device, through the corotation of drive wheel and upset can realize the folding/opening movement of two sets of folded sheets, very big simplification structure complexity to increase efficiency.

Preferably, the folding cover plate is composed of two groups of flat plates hinged with each other at the end part or panels with triangular, trapezoidal and arc-shaped cross sections, certainly, the folding plate also comprises tarpaulin, and under the condition that the tarpaulin is adopted, hard support rods are arranged on four sides or at least two sides of the tarpaulin.

Preferably, the power drive device is located on the outer end surface of the short-side or long-side.

Preferably, the device also comprises a protective cover, and the transmission chain is arranged outside the protective cover; this technical scheme further increases the life of chain and reduces the maintenance.

Preferably, the power driving device is a motor.

Detailed Description

As shown in fig. 1-3, a cargo vehicle turnover type canopy device comprises a cargo carrying box 1, wherein the cargo carrying box 1 is enclosed by a long side 11 and a short side 12, two sets of folding cover plates (2, 3) are arranged on the upper side inside the cargo carrying box 1, a rotating shaft 4 is installed at one end of each folding cover plate (2, 3), the rotating shaft 4 is rotatably installed on the short side 12 of the cargo carrying box 1, a transmission gear 5 is arranged in the middle of the long side 11 on two sides of the cargo carrying box 1, the transmission gear 5 is composed of two sets of meshing wheels (51, 52) which are meshed with each other and chain gears (53, 54) arranged at the side ends of the meshing wheels (51, 52), chain gears (6, 7) are arranged on the short side 12 of the cargo carrying box 1 on two sides of the transmission gear 5, one of the chain gears (6) is connected with a power driving device, the chain gears (53, 54) are connected with, 7) the folding mechanism is connected with the cargo carrying box 1 through transmission chains (8, 9), the top surfaces of the transmission chains (8, 9) are fixedly connected with the other ends of the folding cover plates (2, 3), and the folding cover plates (2, 3) move forwards or backwards through the transmission chains (8, 9) to realize folding and cover or open the cargo carrying box 1.
