Description

[Correction 20.11.2015 by Rule 26] Cylinder embedded vehicle lift device

The present invention relates to a cylinder-embedded vehicle lift apparatus, and more particularly, a lifting part including a cylinder and a piston rod providing a lifting force by hydraulic pressure is embedded in the ground, and a support fixed to the piston rod of the lifting portion on the ground. By maintaining the protruding state only, the present invention relates to a cylinder-embedded vehicle lift device that allows workers or pedestrians to prevent safety accidents caused by collisions and to improve work efficiency by minimizing the interference to work lines. .

In general, a vehicle lift device is a device configured to lift a vehicle to a certain height by using a lifting means such as a hydraulic cylinder and to perform maintenance work of the vehicle under it.

The vehicle lift apparatus is divided into two stocks and four stocks according to the number of pillars, and has a pillar shape and a gate shape according to the shape of the pillar, and an X shape according to the shape of the arm lifting the vehicle body.

The two stocks are two pillars (or posts), four stocks are four pillars, and the pillars are formed at regular intervals from each other, and the gate type has a cross beam between the pillars and the pillars. It is a connected form.

In the two-column gate lift device, as shown in FIGS. 1 and 2, two posts 10 are installed upright on the ground with a predetermined distance from each other, and the cross beam 30 is disposed on the posts 10. ) Is installed to connect the posts 10 to each other.

Each of the posts 10 is formed with a guide groove 11 in the longitudinal direction on the side facing each other, the fixing member (P) on the rod (13a) of the hydraulic cylinder 13 located below the inside of the post (10) By connecting the carry (12) through the guide groove (11) of the post (10) while maintaining the fitted state to be fitted up and down, it is installed to move up and down.

The support 12 is connected to the carry 12 to lift a vehicle body (not shown), and is installed to be lifted and lowered by the carry 12, and the support arm 14 is folded horizontally or in a longitudinal direction. Installed so that it can be stretched.

Then, when one carry 12 is elevated, the two carry 12 are connected to each other by a wire W so that the other carry 12 also operates simultaneously, so that the cross beam can guide the wire W. The inner carry is connected to the upper side of the inner carry 12 on one side and the other side is connected to the upper side of the inner carry 12 while the other side is connected to the upper guide roller R1 installed on both sides of the inner carry through the lower guide roller R2 located at the bottom of the post 10. It is connected to the lower part of (12).

Therefore, when both hydraulic cylinders are operated at the same time, the wire connected to the upper portion of the carry rises, and the carry on the opposite side is connected to the lower portion of the carry 12 through the lower guide roller R2 located at the lower portion thereof. As 12) is pulled up, the wire is pulled as much as it is released from one side, and the wire is always in a state of holding while maintaining the proper tension.

In addition, the carry 12, which is lifted up due to oil leakage of the hydraulic cylinder 13, may sit down. At this time, a worker who is working under the carry 12 may suffer a serious injury. In order to prevent such a safety accident, the ratchet mechanism L is installed at one post 10.

Looking at the operation of the conventional two-column gate lift having such a configuration, first, the vehicle is advanced so that the support arms 14 are positioned on both sides of the vehicle, and the position is adjusted while the support arms 14 are rotated and stretched.

The hydraulic cylinder 13 is then operated to raise the carry 12, and at the same time the support arm 14 fixed to the carry 12 is also raised to raise the vehicle to a predetermined height.

At this time, the upper and lower guide rollers (R1) (R2) is configured to operate at the same time while holding the tension of the wire (W) while supporting both the carry (12).

As in the prior art, the two- or four-stock lift apparatus is restricted by the movement line of the worker by a column (or post) that is erected at a certain height on the ground, and inadvertently a safety accident such as a collision may occur. There are several problems such as reduced space.

In addition, the conventional lift apparatus is exposed to the outside as a whole, it is easily aging due to the external environment, there is a problem that the service life is shortened by this.

In particular, the car wash or gloss companies, such as using the water or chemicals, there is a problem that there is a limit of use that the lift devices exposed to the outside could not be used due to the aging of the corrosion easily.

In addition, the auxiliary mechanism is not limited to the footrest 128 or the auxiliary footrest 129, and may be used as an auxiliary mechanism having a variety of structures depending on the size of the vehicle or the object to be attached to and detached from the rotation support 124, Any means that can stably support a vehicle or an object can be used.

In some cases, the vehicle or the object may be supported only by the rotation support 124 without mounting the auxiliary mechanism.

On the other hand, the rotation part 1242 of the rotation support 124 is formed with an insertion hole into which the rotation shaft 126 is inserted.

The rotation shaft 126 is configured between the central support 122 and the rotation support 124 to serve as a center to rotate the rotation support 124 at an angle. The pivot shaft 126 may be composed of a fastening means composed of a pin or a bolt and a nut, and any means may be used as long as the pivot shaft 124 is easily supported to rotate at a predetermined angle.

Looking at the state of use of the cylinder-mounted vehicle lift device configured as described above are as follows.

First, the cylinder 112 of the lifting unit 110 is maintained in the ground.

Then, the position of the pivot stand 124 of the support 120 is determined according to the size of the vehicle or the object (hereinafter, described with reference to the vehicle). For example, a vehicle with a large vehicle width such as a large / medium passenger car or a truck is combined with a straight footrest 128 at the end, while a small vehicle, such as a small passenger car, is formed with an 'X' type at each end. Auxiliary scaffold 129 is used in combination. Alternatively, in the case of a motorcycle, a separate auxiliary device may be used in combination.

Subsequently, when the coupling of the auxiliary mechanism to the pivotal support 124 is completed (may be omitted in some cases), the vehicle is moved to a position that can be stably supported by the pivotal support 124.

Then, when the lifting force provided from the pressure pump 116 is provided to the cylinder 112, the piston rod 114 configured in the cylinder 112 is raised to a certain height.

Accordingly, work such as cleaning, gloss or maintenance of the elevated vehicle is performed.

In this case, the piston rod 114 is configured to rotate with respect to the cylinder 112, it is possible to rotate the vehicle in the elevated state during the cleaning, polishing or maintenance work in place. Accordingly, the operator can perform various operations on the vehicle lifted in place.

In addition, when the work on the vehicle is completed, the lowering force is provided in the pressure pump 116, through which the piston rod 114 is lowered, and lowers the vehicle to the ground. In this case, the piston rod 114 is rotated about the cylinder 112, so that the user or operator determines the moving direction of the vehicle to the desired position irrespective of the initial entry position of the vehicle to put down.

Therefore, the vehicle lift apparatus 100 maintains a state in which the elevating unit 110 is buried in the ground, and maintains a state in which only the support unit 120 protrudes on the ground, thereby preventing the worker or pedestrians from colliding with the collision. The accident can be prevented in advance.
