Description

Horizontal stabilizer with angle limiting assembly

[0001] 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.

[0002] Typically, outriggers are extended to stabilize the vehicle or trailer body and allow it to rest on the ground, leveling it. This is especially true for heavy equipment vehicles or trailers, where failure to maintain a stable, level surface can lead to a risk of rollover. Therefore, outrigger installation is paramount.

[0003] 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, gear, load, and 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 fix the heavy equipment on the ground.

[0004] Horizontal stabilizers, such as outriggers, operate to level a vehicle or trailer. As the load descends, the footpegs contact the ground. A level sensor measures the tilt and then performs labeling. However, manually adjusting the vehicle's level can be inaccurate and time-consuming.

[0005] In addition, in order to shorten this working time, the load of the horizontal stabilization device was raised and lowered to raise the footrest off the ground, so when the vehicle or trailer was moved, the footrest moved freely and was subject to impact.

[0006] (Patent Document 1) Republic of Korea Publication No. 10-2011-0117521 (October 27, 2011)

[0007] 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 that allows quick visual confirmation before checking angle information with a horizontal sensor when the slope required for labeling is greater than the slope required for labeling at the moment the footrest touches the ground before labeling.

[0008] In addition, a horizontal stabilization device having an angle limiting assembly capable of limiting the movement of the footboard when moving a vehicle or trailer while lifting the load and keeping the footboard off the ground is provided.

[0009] 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.

[0010] 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 so that the degree of inclination of the vehicle or trailer can be visually confirmed before being confirmed by a horizontal sensor.

[0011] 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.

[0012] 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 slope of the ground, the foot plate is prevented from touching the ground due to the interference between the position pin and the position pin insertion groove.

[0013] 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.

[0014] In addition, the footrest is characterized in that it is made to tilt according to the slope of the ground by coming into contact with the ball joint.

[0015] In addition, the diameter of the position pin and the diameter of the position pin insertion groove are characterized in that they can be formed according to the operable angle to be limited.

[0016] In addition, the larger the clearance between the position pin and the position pin insertion groove, the larger the useful angle, and the smaller the clearance, the smaller the angle.

[0017] 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.

[0018] In addition, the horizontal stabilization device having an angle limiting assembly according to the present invention can quickly determine the inclination of the ground with the naked eye, thereby solving the problem of wasting time in manipulating the horizontality of the vehicle body.

[0019] 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.

These embodiments are provided solely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined solely by the scope of the claims.

[0037] The specific details for implementing the present invention will be described in detail with reference to the attached drawings. Regardless of the drawings, the same reference numerals refer to the same components, and "and / or" includes each and every combination of one or more of the mentioned items.

[0038] The terminology used herein is for the purpose of describing embodiments and is not intended to limit the present invention. In this specification, singular forms also include plural forms, unless specifically stated otherwise. As used herein, the terms "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components in addition to the components mentioned.

[0039] Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in their common sense to those of ordinary skill in the art to which the present invention pertains. Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0040] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0041] 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 AA of the lower part of a horizontal stabilization device having an angle limiting assembly according to the present invention as shown in FIG. 2.

[0042] Referring to FIGS. 1 to 3, a horizontal stabilization device (1) having an angle limiting assembly according to the present invention is a horizontal stabilization device installed on a vehicle or trailer, and largely includes a load (10), a foot plate (20), and an angle limiting assembly (30).

[0043] 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.

[0044] 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.

[0045] Next, the footrest (20) is raised and lowered by the above load (10) and supports the vehicle body by making contact with the ground.

[0046] 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 with a horizontal sensor.

[0047] 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).

[0048] FIG. 4 is a drawing showing an angle limiting plate constituting a horizontal stabilization device having an angle limiting assembly according to the present invention.

[0049] 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) refers to a hole into which a position pin (60) is inserted.

[0050] In addition, the angle limiting plate (40) may be configured to 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.

[0051] 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 fix the position pin (60) to the horizontal stabilization device.

[0052] FIG. 5 is a drawing showing a position pin constituting a horizontal stabilization device having an angle limiting assembly according to the present invention.

[0053] 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).

[0054] The above position pin (60) is designed so that if the interference of the position pin insertion groove (41) of the angle limiting plate mounted on the foot plate (20) is greater than the required slope of the ground, the foot plate (20) is prevented from touching the ground due to the interference of the position pin insertion groove (41).

[0055] 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.

[0056] Figure 6 is a drawing showing a pressure sensor constituting a horizontal stabilization device having an angle limiting assembly according to the present invention.

[0057] Referring further to FIG. 6, the pressure sensor (70) is formed on the position pin (60) and serves to generate a warning sound the moment the position pin (60) touches the angle limiting plate (40).

[0058] For example, the pressure sensor (70) may be formed on the cylindrical position pin (60) in a form that surrounds the position pin (60).

[0059] 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) allows this to be quickly confirmed with the naked eye.

[0060] 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 position 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.

[0061] Afterwards, when the footrest (20) touches the ground, the horizontal stabilization device (1) is auto-labeled.

[0062] Accordingly, the horizontal stabilization device (1) equipped with an angle limiting assembly according to the present invention has the effect of enabling the required ground inclination to be confirmed in advance before being recognized by the horizontal sensor. In addition, it has the effect of enabling the local ground inclination of each horizontal stabilization device to be confirmed.

[0063] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
