Outrigger variable Apparatus of Vehicle for Industry}

The present invention relates to an outrigger variable device for an industrial vehicle, and more particularly, an outrigger for an industrial vehicle that can stably and support a vehicle body of heavy equipment such as a crane or a telescopic handler from the ground. It relates to a variable device.

Industrial vehicles are used in construction sites, such as industrial construction, buildings, civil and factory buildings, construction sites, etc. Usually, heavy equipment includes forklifts, cranes, telescopic handlers, and the like.

A forklift is a work such as loading a work used in a construction site or an industrial site at a vehicle or a predetermined position, or unloading a loaded work at a short distance and moving the work at a short distance. It is to do limited work such as letting go.

On the contrary, cranes are fixed and mobile, and fixed cranes include tower cranes for lifting and lowering a workpiece above a certain height depending on the work range and ability. A mobile type is usually fixed when lifting and lowering a workpiece. However, there is a telescopic handler or the like that can move a workpiece below a predetermined weight to a predetermined distance.

The telescopic handler can perform a function of a forklift and a crane at the same time, and is widely used in an industrial site or a building site. The telescopic handler can carry the moving parts of a high-rise apartment or the work of the construction site according to the working capacity, and can work on a narrow road in the small case.

As such an industrial vehicle, a crane or a telescopic handler usually works in a state where a plurality of outriggers are provided and fixed on one side of the top of the wheel of the vehicle for the stability of the work when lifting and lowering the workpiece. In other words, the outrigger typically allows the vehicle to be lifted from the ground with four support points on a fixed height. The outrigger is configured to support the lower end of the vertical support (commonly referred to as a shoe or shoe assembly) provided in the vertical direction at the tip of the outrigger beam with respect to the ground.

The outrigger of the conventional industrial vehicle has an outrigger beam box installed at the front and rear of the vehicle from the main frame of the lower driving body, and the outrigger beam is extended in the left and right directions along the guide surface of the box, and is perpendicular to the ground. It is composed of a structure to fix the shoe on the ground by extending the bent jack cylinder. When the outrigger beam is installed in this way, it is adopted to secure safety to prevent the vehicle from overturning from the moment of the boom and the heavy material during the operation of the industrial vehicle. In this case, depending on the size and weight of the vehicle, the auxiliary outrigger may be applied to the front and rear of the vehicle, or the structure that fixes and supports the outrigger beam and the box by crossing the X letter may be applied. It was.

However, this only prevented the possibility of the vehicle overturning only to the left and right sides of the normal vehicle, and almost no action was taken on the possibility of overturning forward and backward.

Therefore, the present invention is designed to extend the outrigger beam of the industrial vehicle to the front and rear, including the left and right direction from the main frame of the lower drive body to minimize the possibility of the vehicle overturning during the operation of the industrial vehicle. It is an object to provide an outrigger variable device for an industrial vehicle.

In order to achieve the above object, a plurality of main frames spaced at predetermined intervals by a plurality of cross channels as a lower driving body of an industrial vehicle; A slide beam which is stretched and slides in the front-rear direction from the inside of the main frame; A slide box connected to an end of the slide beam by a connecting member; By providing an outrigger variable device for an industrial vehicle, one end of which is hinged to the cross channel configured between the main frame, the other end is hinged to the side of the slide box, and includes a front and rear slide cylinder that is stretched by hydraulic pressure. Can be achieved.

And the tip of the telescopic boom (4) is connected to the boom carriage (5) that can be attached and detached various work machines 10 through the link (9).

Figure 2 is a side view of the outrigger variable device of the present invention, Figure 3 is a plan view showing an operating state of the outrigger variable device.

Outrigger variable device of the present invention is the main frame (20, 21) that is the main skeleton of the lower drive body of the industrial vehicle, and the outrigger beams, that is, the slide box (60-63) coupled to the front and rear of the main frame One pair is provided.

The main frames 20 and 21 are spaced apart at predetermined intervals by a plurality of cross channels 40 and 50 as the lower drive bodies 6 of the industrial vehicle 1, and are constituted in pairs in the present invention. On the upper end of the central portion of the main frame 20, 21, a bed flange 35 to which the upper pivot 3 is connected is configured. The bed flange 35 is connected to a plurality of hydraulic lines and various wires necessary for control. And between the main frame (20, 21) is composed of a coupling member for rigidity and support.

The slide beam 22-25 is inserted and coupled to a space portion inside the main frames 20 and 21 to be expanded and contracted while sliding in the front and rear directions. The slide beams 22-25 are inserted into and coupled to the front and rear of the main frames 20 and 21, respectively.

The slide box 60-63 is connected to the end of the slide beam 22-25 by a connecting member 26-29, such as a flange, and between the slide box 60-63 and the slide beam 22-25. One or more supports 30-33 are combined for support stability. The slide boxes 60-63 are coupled to the front and rear by a pair at right angles to the main frames 20 and 21, and the jack cylinders 68-71 to the left and right sides of the slide boxes 60-63. The combined slide beams 64-67 are stretched and slid by hydraulic pressure. At the end of the jack cylinder 68-71, a shoe 72-75 in contact with the ground is coupled.

Next, one end of the slide cylinders 42 and 52 is hinged 45 and 55 to the cross channels 40 and 50 formed between the main frames 20 and 21, and the other end of the slide cylinders 60 to 63. Hinge 46, 56 is coupled to the side of the stretched by the hydraulic, is configured in the front and rear, respectively. The slide cylinders 42 and 52 slide and slide the slides 44 and 54 from the cylinder by hydraulic pressure. The front slide cylinder 42 and the rear slide cylinder 52 can be operated simultaneously or selectively.

It describes the operation of the outrigger variable device of the industrial vehicle of the present invention having such a configuration. First, referring to the drawing of the pretrigger state of the outrigger variable apparatus of FIG. As the state inserted into the main frame 20, 21, the slide cylinders 42 and 52 between the main frames 20 and 21 are in the state which pulled the slide boxes 60-63 hydraulically. The slide boxes 60-63 are also in a state where the slide beams 64-67, the jack cylinders 68-71, and the like are reduced. In this case, the vehicle 1 can move as the wheels of the front and rear wheels of the lower drive body 6 are in contact with the ground.

In the state of FIG. 4, after the vehicle 1 is moved to the position where the driver intends to work, the position of the outrigger may be selected and adjusted through a control panel that manipulates the position and expansion of the outrigger.

Therefore, in the drawing showing the operating state of FIG. 3, when the driver operates the hydraulic pressure of the front and rear slide cylinders 42 and 52 provided between the main frames 20 and 21, respectively, or simultaneously, the slide cylinder 42, Slide 44, 54 extends from 52, and slide boxes 60-63 coupled with hinges 46, 56 are pushed forward and backward, respectively, by extension of slides 44, 45. This is because the extension of the slides 44 and 54 stretches the slide beams 22-25 in the main frames 20 and 21 to the outside to push the slide boxes 60-63. As such, the slide boxes 60-63 connected to the slide cylinders 42 and 52 and the slide beams 22-25 of the main frames 20 and 21 at the front and rear are slid forward and backward to the desired position of the driver. Can be stretched.

When the position of the outrigger is set to the front and rear in this way, the slide beams 64-67 inserted into the slide box 60-63 are extended to adjust the left and right fixed positions, and the fixed position is set. The jack cylinders 68-71 formed at the ends of the slide beams 64-67 are respectively lowered and fixed to the ground. At this time, it is preferable that the shoe 72-75 fixed to the ground is attached to the lower end of the jack cylinder 68-71.

The outrigger extended and fixed in this way can fix and support the vehicle 1 at a wider position, and can adjust the support distance of the vehicle 1 from the ground, so that the vehicle is overturned during work such as lifting and lowering heavy weights. The risk can be minimized. In order to reduce and restore the outrigger in the extended and fixed state to the state of FIG. 4, the operation may be reversed.

And the positioning and extension and reduction of the outrigger is made by the operation of the hydraulic system connected to the vehicle (1).

The outrigger variable device of the industrial vehicle of the present invention according to the above-described embodiment is configured to combine the slide box with the outrigger mounted on the front and rear of the main frame of the lower drive body to the front and rear and left and right of the vehicle. It can be adjusted to secure the position of the trigger, and the operation of heavy equipment such as cranes and telescopic handlers for lifting and supporting heavy weights minimizes the risk of the vehicle overturning and secures an improved working range. The present invention is not limited to the above-described embodiments, and can be easily changed or replaced by those skilled in the art.
