Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a wing vane opening / closing device.

[0002]

[Prior Art]

 A front wall is erected on the front end of the loading platform, a door frame is erected on the rear end, and a support beam is stretched between the front wall and the center of the top of the door frame. In a wing car in which a V-shaped vane is pivoted up and down and is automatically hinged, a hydraulic cylinder is mounted between the front and rear ends of the L-shaped vane and the front wall and the top of the door frame, and the hydraulic cylinder expands and contracts. The blade opening / closing device of a wing vehicle configured to open and close the blade having the L-shaped cross section by using the hydraulic pump and the electric motor to expand and contract is widely used because the cargo handling work is easy.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional blade opening / closing device for a wing vehicle, as shown in FIG. 3, since a hydraulic unit including a hydraulic pump and an electric motor that expands and contracts a hydraulic cylinder is attached to the lower part of the loading platform, the front wall and the door are closed. In order to feed oil to the hydraulic cylinder mounted on the top of the frame, attach it to the lower part of the bed floor and pipe to the front wall and the rear door frame, and further in the corner post of the rear door frame and the corner of the front wall. It was necessary to pipe in the pillars, and these pipes cannot be connected in a straight line, and must be bent and installed each time in order to pipe from the hydraulic unit into the corner pillars of the front wall and the rear door frame. And, the piping work was very troublesome.

On the other hand, it is desirable that the hydraulic piping is as short as possible and has few bent portions from the viewpoints of durability, ease of mounting work, and economy.

[0005]

[Means for Solving the Problems]

 The present invention solves the above problems by providing a hydraulic unit, which is composed of a hydraulic pump and an electric motor for expanding and contracting the hydraulic cylinder, projecting above the outer surface of the front wall of the wing vehicle and provided near the hydraulic cylinder. is there.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 shows a perspective view of a wing vehicle shown by a chain line, in which a blade opening / closing device according to the present invention is applied, and Fig. 2 is a view taken along the line AA of Fig. 1. Fig. 3 shows the details of the parts, and Fig. 3 shows a state in which a conventional blade opening / closing device is applied to the entire perspective view of the wing car shown by the chain line.

FIG. 3 shows an ordinary wing trailer, in which a front wall 12 is erected at the front end of the luggage carrier 10 and a door frame 14 is erected at the rear end thereof, and the front center of the front wall 12 and the door frame 14 is centered. A support beam 16 is stretched between the parts, and blades 18, 18 having an L-shaped cross section are hinged to the left and right sides of the support beam 16 so as to be vertically rotatable. The hydraulic cylinders 20, 20 ... Are mounted between the ends and the front wall 12 and the top of the door frame 14, and the blades 18, 18 having an L-shaped cross section are opened and closed by expansion and contraction of the hydraulic cylinders 20, 20. It is composed.

A box 22 accommodating a hydraulic unit such as a hydraulic pump and an electric motor for expanding and contracting the hydraulic cylinders 20, 20 ... Is attached to a lower portion of the luggage carrier 10, and the box 22 is connected to the front wall. Also, piping is provided in the hydraulic cylinders 20, 20 ... Installed on the top of the door frame.

In the conventional piping shown in FIG. 3, oil supply pipes 24, 24, ... For connecting the box 22 to the left and right ends of the front wall 12 and the rear door frame 14 are provided on the lower surface of the floor 10. In order to attach it, it was inserted into a square tube or the like and fixed to the lower surface of the floor 10. Then, the square tube was bent at the lower part of the front wall and the door frame and inserted into the inside of each corner post 13 and 15 to the upper part. It was connected to the mounted hydraulic cylinder 20.

Accordingly, the work of attaching the oil feed pipes 24, 24, ... To the lower surface of the floor 10, the work of bending and inserting the oil feed pipes 24, 24 ,. The oil feed pipes 24 and 24 for piping to the left and right ends of the front wall portion 12 and the rear door frame 14 are required.

As shown in FIG. 1, the present invention provides a box 22 accommodating a hydraulic unit such as a hydraulic pump and an electric motor so as to project above the outer surface of a front wall 12 of a wing vehicle to form a hydraulic cylinder 20, 20.・ It is intended to eliminate the above waste by installing it near.

Further, as shown in FIG. 2, if the oil feeding pipes 24, 24 are inserted inside the support beam 16, the oil feeding pipes 24, 24 are protected, so that a special mounting square pipe is not required.

Although the present embodiment relates to the wing trailer as described above, it is needless to say that the present invention can be applied to a case where it is mounted on a truck, and other various design changes can be made without departing from the spirit of the present invention. .

[0014]

[Effect of the device]

 According to the present invention, the box accommodating the hydraulic unit is provided so as to project above the outer surface of the front wall of the wing vehicle and is provided near the hydraulic cylinder, so that the pipe for attaching the oil pipe to the bottom surface of the floor is attached. And installation work, bending work, oil pipes to be inserted inside the corners of the front wall and door frame, and installation work, and oil pipes for piping to the left and right ends of the front wall part and rear door frame, respectively. If the oil pipe is inserted inside the support beam without doing so, the oil pipe is protected.Therefore, there is no need for a special mounting square pipe, and the length of the oil pipe can be minimized. Effect is large.
