Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a signboard lift device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sign lift apparatus for a vehicle, and more particularly, to a vehicle equipped with a signpost for blocking a lane during a road construction work and guiding a vehicle to another lane.

Generally, on the road, various tasks such as painting new lanes, repairing roads, or collecting fallen objects should be carried out from time to time. In the course of road construction, a vehicle equipped with a signpost is used to guide the vehicle to a safe lane without interrupting the traffic of the vehicle being driven.

In the domestic registration utility model 20-0148843, 'road construction sign' has been introduced.

This technique is fixed type that is used to install construction signs on the ground.

In recent years, there has been used a method of installing such a construction signboard in a freight car and slowing down and guiding it.

A piston rod connected to the bracket and operated to be lifted and lowered, a piston rod coupled to the vehicle body, and mounted vertically to the vehicle body; And a power supply unit for supplying hydraulic or pneumatic pressure to the cylinder unit and the cylinder unit to move the piston rod up and down.

Accordingly, when power is supplied to the cylinder unit, the piston rod rises, and the bracket and the support stand rise together with the sign board rising together. The descent proceeds in the reverse order.

However, in the related art, there is a problem that the distance between the support and the cylinder unit is large, so that deformation of the bracket due to the load of the sign is generated, or shaking occurs in the up and down operation.

Therefore, noise is generated due to the shaking motion during the ascending / descending operation, and the operation is not smoothly performed, which is disadvantageous in that it is not robust.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a cylinder unit and a sign board which are as close as possible to each other to minimize the occurrence of rocking, And to provide a vehicle sign platform capable of efficient driving.

In order to accomplish the object of the present invention, an embodiment of the present invention is a cylinder unit mounted on a vehicle equipped with a sign for guiding a lane during a road construction work, the cylinder unit being vertically mounted on a floor of a vehicle, A power supply for supplying hydraulic or pneumatic pressure to the cylinder unit to move the piston rod up and down; And a lift to which the sign is affixed, which is attached to the outside of the cylinder unit and is connected to the piston rod and is operated to ascend and descend.

The cylinder unit has a lower end attached to a base plate formed on the bottom of the vehicle body,

One end of the fixing bracket is connected to one side of the upper portion, and the other end of the fixing bracket is connected to the front wall of the car body loading box.

Wherein the lift has an opening formed in a lower portion thereof so that a cylinder unit is inserted therein, a space formed in the inside of the lift, and an elongated hole formed in the longitudinal direction; A fixing member formed on the inner space of the tube and coupled with the piston rod; And a fastening piece formed on one side of the tubular body and to which a sign is attached. The fastening bracket mounted on the cylinder unit through the long hole is inserted and coupled.

According to the present invention, the distance between the cylinder unit and the sign board can be minimized to reduce the occurrence of shaking considerably, thereby preventing the occurrence of noise and troubles, thereby enabling more robust and efficient driving.

Fig. 6 is a side view of the vehicle according to the present invention. Fig. 6 is a side view of the vehicle according to the present invention. And Fig.

1 to 6, the sign board platform according to the present invention is mounted on a vehicle 100 provided with a sign 200 for guiding a lane during construction work of a road, A cylinder unit 2 coupled to the body floor 120 and vertically mounted on the body floor 120; A power supply part 3 for supplying a power supply part to the cylinder unit 2 to raise and lower the piston rod 22; And a lift 6 attached to the rear of the sign 200 and connected to the outside of the cylinder unit 2 and connected to the piston rod 22 to move up and down.

The lower end of the cylinder unit 2 is bolted to a base plate 21 formed on the bottom 120 of the vehicle so as to be mounted vertically so that hydraulic or pneumatic power is used as a power source. .

The other end of the fixing bracket 27 is connected to the front wall 140 of the car body loading box.

The power supply unit 3 is a hydraulic pump or an air compressor that supplies hydraulic pressure or pneumatic pressure and is installed at the center of the vehicle body floor 120 and connected to the cylinder units 2 on both sides to provide power.

An opening 61 is formed in the lower portion of the lift 6 so that the cylinder unit 2 is inserted therein. A space 60 is formed in the interior of the lift 6, a long hole 602 is formed in the longitudinal direction, ; A fixing member (62) formed on the inner space of the tube (60) and coupled with the piston rod (22); And a fastening piece portion 64 formed at one side of the tubular body 60 and to which the sign 200 is attached.

A fixing bracket 27 having one end mounted on the cylinder unit 2 through the elongated hole 602 of the tubular body 60 is projected to the outside.

The other end of the protruding fixing bracket 27 is bolted to the front front wall 140 of the vehicle 100 and mounted thereon.

A guide member 28 is attached to the lower portion of the inner circumferential surface of the tube 60 of the lift 6 and is coupled to the outer circumferential surface of the cylinder unit 2 to prevent shaking of the lift 6 during the elevating operation.

Hereinafter, the operation of the present invention will be described.

A power supply is mounted at the center of the vehicle body bottom 120, and the lift 6 and the cylinder unit 2 are disposed apart from each other and fixed to both sides thereof.

Thereafter, the sign 200 is attached and fixed to the lifts 6 on both sides.

Thereafter, when the power supply unit 3 is turned on and power is supplied to both cylinder units 2, the piston rod 22 is raised.

The lift 6 is raised in conjunction with the upward movement of the piston rod 22 and the sign 200 attached to the lift 6 ascends.

The lift 6 is attached to the outside of the cylinder unit 2 and the sign board 200 is attached to the lift 6 and the cylinder unit 2 and the lift 6, Since the sign 200 is coupled with a minimum separation distance, it is possible to minimize the loss of force that may occur in the course of raising the lift 6.

In addition, by minimizing the distance between the cylinder unit 2, the lift 6 and the sign 200, it is possible to prevent the clearance at the time of the ascending and descending operation and to prevent the shaking, and the abrasion or breakage of the driving members is prevented And life span can be prolonged.
