Description

Horizontal stabilization device with angle limiting assembly

The present invention relates to a horizontal stabilization device having an angle limiting assembly, and more particularly, to a horizontal stabilization device having an angle limiting assembly for visually checking the degree of inclination of a vehicle or trailer before checking it with a sensor.

In general, outriggers are pulled out to level the body of a vehicle or trailer so that it does not shake. In particular, in the case of heavy equipment vehicles or trailers, if the body is not in a stable horizontal state with the ground, there is a risk of overturning, so the installation of outriggers is of the utmost importance.

An outrigger is used to maintain the stability of work and the horizontality of the body of a heavy equipment vehicle while the vehicle is stationary, and may be configured to include a motor, a gear, a load, and a footrest, and the load is raised and lowered by the driving force of the gear connected to the motor, and the footrest jointly connected to the lower end of the load is supported on the ground, so that it is used to level the body of a heavy equipment vehicle or trailer in a site where the ground condition is uneven, and to secure the heavy equipment to the ground.

Horizontal stabilization devices such as outriggers operate the horizontal stabilization device to label (level) the vehicle or trailer, and when the load is lowered, the footrest touches the ground, and the degree of inclination is checked by the horizontal sensor and then labeling is performed. At this time, there was a problem that the accuracy was insufficient and it was time-consuming because the level of the vehicle body was adjusted manually.

In addition, in order to shorten this working time, the load of the horizontal stabilizing device was raised and lowered to raise the footrest off the ground, so there was a problem that the footrest moved freely when moving the vehicle or trailer and was subject to impact.

The purpose of the present invention is to solve the above-described problem, and to provide a horizontal stabilization device having an angle limiting assembly to enable quick visual confirmation before checking angle information with a horizontal sensor if the angle at the moment when the footrest touches the ground before labeling is greater than the incline required for labeling.

In addition, a horizontal stabilization device having an angle limiting assembly capable of limiting the movement of the step when moving a vehicle or trailer while lifting the load and keeping the step off the ground is provided.

The purposes of the present invention are not limited to the purposes mentioned above, and other purposes not mentioned will be clearly understood by those skilled in the art from the description below.

In order to achieve the above object, a horizontal stabilization device having an angle limiting assembly according to the present invention is a horizontal stabilization device installed on a vehicle or trailer, comprising: a rod that is raised and lowered; a footrest that is raised and lowered by the rod and supports the vehicle body by contacting the ground; and an angle limiting assembly that is installed between the rod and the footrest and is provided so that the degree of inclination of the vehicle or trailer can be visually confirmed before being confirmed by a horizontal sensor.

In addition, the angle limiting assembly is characterized by including an angle limiting plate installed on the foot plate and having a position pin insertion groove formed therein, a position pin inserted into the position pin insertion groove, and a ball joint for fixing the position pin to a horizontal stabilization device.

In addition, the angle limiting assembly is characterized in that, if the interference between the position pin mounted on the ball joint and the position pin insertion groove of the angle limiting plate mounted on the foot plate is greater than the required ground incline, the foot plate is prevented from touching the ground due to the interference between the position pin and the position pin insertion groove.

In addition, the angle limiting assembly further includes a pressure sensor installed on the position pin, and the pressure sensor is characterized in that it generates a warning sound the moment it touches the angle limiting plate.

In addition, the footrest is characterized in that it is formed so that the footrest tilts according to the slope of the ground by coming into contact with the ball joint.

In addition, it is characterized in that the diameter of the position pin and the diameter of the position pin insertion groove can be formed according to the operable angle to be limited.

In addition, the angle that can be useful is increased as the clearance between the position pin and the position pin insertion groove increases, and the angle is formed so that the angle becomes smaller as the clearance decreases.

The horizontal stabilization device having an angle limiting assembly according to the present invention has an effect that can be utilized in an existing horizontal stabilization device by applying an angle limiting assembly of a simple structure.

In addition, the horizontal stabilization device equipped with an angle limiting assembly according to the present invention can effectively solve the problem of time-consuming operation of the horizontality of the vehicle body by quickly identifying the inclination of the ground with the naked eye.

In addition, the horizontal stabilization device having an angle limiting assembly according to the present invention has the effect of minimizing shaking of the footboard by the angle limiting assembly when the vehicle or trailer is moving, thereby preventing the footboard from moving freely, thereby resolving damage caused by collision, etc.

FIG. 1 is a drawing showing the overall shape of a horizontal stabilization device having an angle limiting assembly according to the present invention, FIG. 2 is a drawing showing the lower part of a horizontal stabilization device having an angle limiting assembly according to the present invention, and FIG. 3 is a drawing showing a cross-section A-A of the lower part of a horizontal stabilization device having an angle limiting assembly according to the present invention as shown in FIG. 2.

Referring to FIGS. 1 to 3, a horizontal stabilizing device (1) having an angle limiting assembly according to the present invention is a horizontal stabilizing device installed on a vehicle or trailer, and largely includes a load (10), a foot plate (20), and an angle limiting assembly (30).

First, the load (10) is provided to lower the footrest (20) so that it can touch the ground, and is raised and lowered by the operation of the horizontal stabilization device.

For example, although not shown, it can be raised and lowered by the driving force of a gear connected to a motor constituting a horizontal stabilization device (1). This is a common technique, and a detailed description thereof will be omitted.

Next, the footrest (20) is raised and lowered by the load (10) and supports the vehicle body by making contact with the ground.

Next, the angle limiting assembly (30) is installed between the load (10) and the footrest (20) so that the degree of inclination of the vehicle or trailer can be visually confirmed before being confirmed by a horizontal sensor.

More specifically, the angle limiting assembly (30) includes an angle limiting plate (40), a ball joint (50), a position pin (60), and a pressure sensor (70).

FIG. 4 is a drawing showing an angle limiting plate constituting a horizontal stabilizing device having an angle limiting assembly according to the present invention.

Referring further to Fig. 4, the angle limiting plate (40) is installed on the foot plate (20) and a position pin insertion groove (41) is formed. Here, the position pin insertion groove (41) means a hole into which a position pin (60) is inserted.

In addition, the angle limiting plate (40) may have a plurality of fastening grooves formed along the circumference for installation on the foot plate (20), and may be configured to be installed on the foot plate (20) through a fastening member.

The above ball joint (50) is used to allow the foot plate (20) to tilt according to the slope of the ground, and is used to secure the position pin (60) to the horizontal stabilization device.

FIG. 5 is a drawing showing a position pin constituting a horizontal stabilization device having an angle limiting assembly according to the present invention.

Referring further to Fig. 5, the position pin (60) is mounted on the ball joint (50) and is provided so that it can be inserted into the position pin insertion groove (41).

The above position pin (60) is designed to prevent the foot plate (20) from touching the ground due to interference of the position pin insertion groove (41) of the angle limiting plate mounted on the foot plate (20) if the interference of the position pin insertion groove (41) is greater than the required slope of the ground.

Meanwhile, the size of the diameter of the position pin (60) and the diameter of the position pin insertion groove (41) can be formed according to the operable angle to be limited, and the larger the clearance between the position pin (60) and the position pin insertion groove (41), the larger the useful angle, and the smaller the clearance, the smaller the angle.

FIG. 6 is a diagram showing a pressure sensor constituting a horizontal stabilization device having an angle limiting assembly according to the present invention.

Referring further to Fig. 6, the pressure sensor (70) is formed on the position pin (60) and generates a warning sound when the position pin (60) touches the angle limiting plate (40).

For example, the pressure sensor (70) may be formed on the cylindrical position pin (60) in a form that surrounds the position pin (60).

The horizontal stabilization device (1) having an angle limiting assembly according to the present invention having the structure as described above prevents the foot plate (20) from touching the ground when the angle limiting plate (40) mounted on the foot plate (20) and the positioning pin (60) mounted on the ball joint (50) come into contact with each other if the incline of the ground is greater than the required incline, and in particular, when the positioning pin (60) and the angle limiting plate (40) come into contact, the warning sound generated by the pressure sensor (70) enables this to be quickly confirmed with the naked eye.

If the footrest (20) does not touch the ground due to the angle limiting assembly (30), the location is moved and the horizontal stabilizing device (1) is re-driven. If the slope of the ground is less than the required slope, the positioning pin (60) mounted on the ball joint (50) and the angle limiting plate (40) mounted on the footrest (20) do not come into contact, allowing the footrest (20) to touch the ground.

Afterwards, when the footrest (20) touches the ground, the horizontal stabilization device (1) is auto-labeled.

Accordingly, the horizontal stabilization device (1) equipped with an angle limiting assembly according to the present invention has the effect of being able to confirm in advance the required ground inclination before it is recognized by the horizontal sensor. In addition, it has the effect of being able to confirm the local ground inclination of each horizontal stabilization device.

Although the embodiments of the present invention have been described with reference to the above and the attached drawings, those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential characteristics thereof. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
