Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is particularly suited for vehicle handling and repair purposes commonly performed in gas stations, auto repair shops, etc. The built-in horizontal section has the form of a single arm.
This relates to a lifting/tilting device that has a

A device for lifting and tilting a vehicle is known from the published German patent application DE-OS/2165244, which has a base frame of rectangular form.

The long legs of this frame are provided with inwardly extending flanges which serve as supports for the rollers and are connected to each other via a bottom rod, to which are pivotally mounted a pair of arms, the arms being Rotatably connected to a second laterally extending rod. A second pair of arms is installed displaced in the base frame between the rod and the pivot joint. A fastening block is fixed to the end of the second transverse bar, and a collapsible telescoping carrying arm with a carrying device adapted to support the vehicle chassis is fixed to the block. . The bottom rod r is actuated via a second hydraulic ram fixed to the transverse rod and connects said pair of arms near a pivot joint displaced to the base frame. The first hydraulic ram serves to lift the vehicle, and the second hydraulic ram serves to tilt the vehicle.

However, such a device has the disadvantage that it requires the use of two hydraulic rams, making the servicing access to the vehicle chassis relatively complex. The tilting of the vehicle is carried out on the lateral axis by only raising its front or rear part, so that there is no possibility of tilting the vehicle to the side and at the same time there is a small range of tilt angles.

A tilting hoist is also known from German published application DE-O8/2627284, which hoist has two slidably mounted transverse beams and is mounted on a longitudinal beam which is moved via hydraulic rams. It further includes a drive device, a disk placed on the longitudinal beam side that matches the shape of the handle, and a grip device placed on the opposite side, and the grip device holds down the wheel tires from above. Securing the vehicle is done by clamping the wheels and moving the vehicle to one side.
It can be tilted by an angle of 0°.

However, such an arrangement is quite complex in its structure and is associated with some drawbacks.

That is, the vehicle cannot be lifted and the vehicle can only be tilted to one side, preventing access to the area near the wheels during the ride.

The main object of the present invention is to eliminate the above-mentioned disadvantages, and to enable the vehicle to be lifted not only on the platform, but also tilted on both sides, so that the vehicle can be tilted on the longitudinal axis of the vehicle, i.e. to optimally utilize the working area. According to the invention, the object is to obtain a lifting and tilting device which is slidably and rotatably mounted in the main body. The structure incorporates a carriage provided with a longitudinal beam and a rotatable telescoping lever, the longitudinal beam has a fixed carrying arm and a swingable holding leg, and the carrying arm and the telescoping lever are rotatable to the carrier. combined,
This is achieved by providing the carrier with a known telescopic lifting arm and a moving arm, the moving arm being rotatably connected to the main body.

Preferably, the swingable legs are L-shaped and the length of the arms can be adjusted in a known manner.

This swingable leg is preferably provided with a known flexure support device.

In another embodiment of the invention, the above-mentioned supporting device piece together with the swinging holding leg serves to support the upper part of the body during the Vc90' tilting operation.

Furthermore, the moving arm must be pivotally attached to the body, and the moving arm and the carrying arm are connected to a pivot joint in the carrier.

If necessary, the telescopic lifting arm can be folded back after tilting to provide better access to the lower part of the vehicle.

The vertical beam rotatably mounted inside the sliding carriage has an L
It is desirable to provide a drive grate member such as a shape. The sliding carriage can be moved via any suitable drive. Vehicles that are lifted or tilted do not need to be secured with any fasteners.

The arrangement according to the invention has a number of advantages. That is, the structure is simple, there is no need to use fasteners to secure the vehicle, the vehicle is secured using the force generated from the weight of the vehicle, and the vehicle can be tilted to both sides along the longitudinal axis of symmetry, thereby making optimal use of the work area. These are various points such as becoming possible.

Tilting the vehicle to one side is accomplished without the need to raise or lower the vehicle, thereby substantially expediting all repair and maintenance operations.

The arrangement of the present invention operates regardless of the size of the vehicle and, as an added advantage, can be used as a fixed or mobile device.

The arbitrarily determined vehicle lean angle and lift height allow easy access to the entire vehicle chassis as well as the interior areas of the fenders and vehicle drive.

Next, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The arrangement according to the invention has a body 1 in the form of a U-shaped and ultimately double C-shaped beam, on which a sliding carriage 2 is mounted, preferably rollers or other rolling devices. It is incorporated so that it can slide inside the main body 1 at the top. This carriage 2 is driven by a drive device 3, and the device 3 is moved by a drive motor 4. The drive motor 4 and the drive device 3 include an electric motor, a feed screw, a piston,
Hydraulic power units consisting of cylinder assemblies or other types that perform the same function may be used. Crank handle actuation can also be used if an energy source is not available.

A longitudinal beam 5 rotatably mounted through the portion of the sliding carriage 20 located above the body 1 extends, preferably in the form of a cylinder, and is provided with drive channels 6 for vehicle wheels, such as L-shaped. . Inside the carriage 2, a VLL-shaped swinging holding leg 7 is incorporated into a longitudinal beam, the length of which arm is adjusted in a known manner to adjust the holding leg 7 to the height of the vehicle 15.

At the outermost end of the retaining leg 7 is placed a flexure support @8 of known style. A carrier arm 9 is fixedly attached to the longitudinal beam 5 in the region of the sliding carrier 2 and is connected at its second end to the carrier 11 by a pivot joint 17. A moving arm 12 is coupled to the same pivot joint 1T in a position opposite the drive motor 4, the second end of which is mounted for rotation and rotation by a pivot joint 13 in the body 1. A telescopic lever 10 is connected to the carrier 11 by a pivot joint 18, and its second end is connected to the carrier 2 by a pivot joint 16. As will be explained below, the telescoping lever 10 is locked in a known manner by the holding leg 1 in the swiveling position, and the carrier 11 has four known foldable telescoping lifting arms 14 as technical support points for the vehicle chassis 15. It is distributed and set up.

The operation of the lifting/tilting device of the present invention is as follows. Remove the holding legs 7 to the side. A vehicle, for example a car 15, moves on a drive wheel 6 with wheels, for example the left wheel (see FIG. 1), and depending on the desired direction of tilt of the vehicle, the left lifting arm or the right lifting arm 14 is extended to the technical support point for the vehicle chassis. .

If the tilt direction is to the left (see Figure 2), the right lifting arm 1
4 is extended to the technical support point for the car chassis. The holding leg 7 is raised automatically or manually and comes into contact with the upper edge of the vehicle body 150 with the flexible support 8. A drive motor 4 moves a drive device 3 by means of which the sliding carriage 2 is moved in the body 1 towards the pivot joint 13 .

Due to this sliding movement of the carriage 2, the carrier 11 is lifted so as to be pushed upward by the interaction of the telescoping lever 10 and the moving arm 12, such as the rotatably mounted carrying arm 9. At the same time, the longitudinal beam 5 is rotated together with the vehicle 15 by means of a carrier arm 9 fixed to the longitudinal beam 5, so that the left wheel of the vehicle remains on the drive wheel 6. Due to the maximum movement of the sliding carriage 2 towards the pivot joint 13, the carrier 11 occupies a position parallel to the plane of the vehicle 150 floor, so that the helical angle of the vehicle 15 is
° easily. Once the tilting motion of the vehicle 15 is achieved,
Lifting arm 14 allows for easy access to the vehicle chassis as well as all parts of the chassis together with the drive system. The vehicle 15 rests simply on the flexible support 8 of the retaining leg 7 and on the drive tube 6-1, the retaining leg serving as a support against which the upper part of the vehicle body rests.

In the case of a rightward tilt (see FIG. 6), starting from the position shown in FIG.
Technical support points are extended. The holding legs 7 are set aside.

move towards. Carrier 1 is moved by sliding of Carriage 2.
1 is a rotatably mounted carrying arm 9 and a telescopic lever 1
0 and the moving arm 12, it rises so as to be pushed upward. The rotation of the longitudinal beam 50 caused by the action of the carrying arm 90 has no effect on the tilt of the vehicle since the left wheel of the vehicle 15 is never resting on the drive wheel 6. Vehicle 15 is stabilized with its right wheel resting on the foundation.

The frictional force generated is sufficient to immobilize the vehicle 15. Maximum movement of the carriage 2 towards the pivot joint 13 results in a vehicle inclination angle of '40'.

In order to apply the configuration of the invention as a leather hoist, the lifting arm 14 is divided into four technical support points for the vehicle chassis 15, and at the same time the holding legs 7 are removed aside and the telescopic lever 10 is locked. The telescoping lever 10 then functions as a straight connector. The drive motor 4 moves the drive device 3, which moves the sliding carriage 2 towards the pivot joint 13 until the carrying arm 9 and the telescopic lever 10 reach a vertical position, so that the vehicle 15 is It is lifted and placed on the lifting arm 14.

As will be readily understood, the arrangement according to the invention can be made as a mobile device and can be used at any location by fixing the body 1 on the leather, and furthermore, by the use of drive guides, as is well known, the vehicle 15 can be It is also possible to extend the drive groove 6 beyond the height of the longitudinal beam 5. This configuration can also be produced as a fixing device, i.e. the main body 1
The system is embedded in a foundation and installed at a gas station, etc., and eventually moved onto a low-chassis trailer to form a mobile refueling service device.

Modifications within the scope of the invention other than those described above will occur to those skilled in the art in view of this disclosure. For example, the structure of the present invention can be used for services such as agricultural implements, flotation equipment, sailing ships, etc.
Drive shaft 6, deflection support device 8, holding leg 7, and time arm 1 for use in yachts, fish boats, motor boats, etc.
4. Changes to the attachment of the running wheels to the main body 1 are expected.

Accordingly, the above description of the invention is illustrative in nature and not necessarily in a restrictive sense, with the invention being properly defined and scoped by the appended claims.
