The passenger car lift comprises a base with two struts mounted on it with load gripping devices having drive carriages with telescopic beams, each carriage having two curved transverse upper and lower walls connected to the front and rear walls at the junction with the beams, with the formation closed box shape. Telescopic beams are made in pairs so that the length of one beam from a pair exceeds the length of the other beam.

Description

The utility model relates to lifting and handling equipment and can be used for maintenance and repair of cars.

A number of technical solutions of a similar purpose are known from the prior art, for example, from US Pat. US 4715477, IPC 7 B 66 F 7/28, dated December 29, 1987, from US Pat. US 2234455, B 66 F 7/02, 08/20/2004, from RU 2575 U1, B 66 F 7/02, 08/16/1996, which disclose a structure for elevators for passenger cars, comprising a base with two struts mounted on it with load gripping devices, having drive carriages pivotally mounted on them with the possibility of rotation and fixing in the horizontal plane of the beams having supports for the car.

Along with the advantages inherent in the above solutions to achieve the objectives, they all have one significant drawback, which is to limit the range of cars served due to their low receiving height, which is typical for foreign models, as well as low stability of the raised car due to insufficiently rigid carriage designs.

The closest to the proposed utility model for the combination of essential features is a car lift containing a base with two racks assembled on it assembled with load gripping devices having drive carriages pivotally mounted on them with the possibility of turning and fixing in a horizontal plane telescopic beams with supports for the car at the ends (see RU 2575 U1, IPC 7 В 66 F 7/02, 27.05. 2000).

The well-known car lift has low stability of the raised car due to the insufficiently rigid construction of the carriages and does not provide a wide range of serviced cars.

The technical result when using the utility model is to increase the rigidity of the carriages of the load gripping devices, which makes it possible to increase the stability of a car raised for maintenance and repair, and to expand the range of serviced cars having a low landing and a different base and gauge.

The specified technical result is achieved in that in a car lift, comprising a base with two struts mounted on it assembled with load gripping devices, having drive carriages pivotally mounted on them with the possibility of turning and fixing in a horizontal plane telescopic beams with supports for the car on at the ends, each carriage at the junction with the beams has two curved transverse upper and lower walls connected to the front and rear walls to form a closed box-shaped, with telescopic beams made in pairs so that the length of one beam of a pair exceeds the length of another beam, and for fixing the telescopic beams along the angle of rotation under load, locking devices are provided that are automatically released when the carriages reach the lower position, and supports for the car at the ends of the beams are made screw and their upper level is located above the level of the telescopic beams.

The essence of the claimed utility model is illustrated by drawings.

Figure 1 shows a lift for cars, a General view;

figure 2 is the same, view a in figure 1;

figure 3 is the same, the remote element B in figure 1;

figure 4 is the same, view In figure 3.

Lift for cars (figure 1) is a floor lifting mechanism, consisting of two racks 1.2 s

3. Each rack 1, 2 has a drive device 4. Racks 1, 2 are installed on the base 5. Inside the base 5 is a chain gear 6 for synchronizing the drives of both racks 1, 2. A control panel 7 is installed on the rack 1, from which control of the operation of the lift when lifting and lowering the gripping devices 3.

Each load gripping device 3 consists of a carriage 8, a short telescopic beam 9, a long telescopic beam 10, two axles 11 and two locking devices 12 for fixing the telescopic beams along the angle of rotation under load, while the telescopic beams 9, 10 of the load gripping devices 3 are made in pairs so that the length of one beam from a pair exceeds the length of the other beam. The carriages 8 are installed with the possibility of moving up and down along the entire height of the racks 1, 2.

Telescopic beams 9 and 10 have the same design and have the possibility of rotational motion relative to the axes 11 at an angle of 90 °; the stops for them are the walls of the carriage 8. Each telescopic beam is made integral and has a pivot beam 13 that is directly connected to the carriage 8 by an axis 11. Inside the pivot beam 13 there is a retractable beam 14, which, when extended, changes the total length of the telescopic beam. At the end of the retractable beam 14, a screw support 15 is installed, which directly abuts against the bottom of the car. Screw support 15 has the ability to adjust the height above the level of the retractable beam 14.

Changing the rotation of the telescopic beams 9.10 makes it possible to bring them under the supporting technological places on the bottoms of cars of various designs and sizes. To fix the beams 9.10 in certain angular positions under load, locking devices 12 are provided. When the carriages 8 reach the lower position, the locking devices 12 are automatically unlocked, and the beams 9, 10 are freely removed from under the vehicle. Main elements

the locking device 12 are a gear sector 16 with internal teeth and a gear wheel 17. When the teeth of the sector 16 and the wheel 17 mesh, the position of the beam is fixed, and when the gear is released, the beam is released. The disengagement occurs due to the vertical displacement of the gear sector 16 relative to the gear wheel 17.

The implementation of the curved design of the carriages 8, consisting of two curved transverse walls 18 of the upper and lower, rear wall 19 and the front wall 20, allows you to go around the base 5 and lower the telescopic beams 9.10 almost to the floor level, which is very important to improve the conditions for opening the doors of the serviced a car. The walls 18, 19, 20 are rigidly connected by welding into a closed box-shaped structure, which significantly increases the rigidity of the carriage 8. Placing the upper level of the screw support 15 above the level of the swing beam 13 allows the telescopic beams 9, 10 to be freely passed under vehicles with low thresholds and does not interfere with opening front door of the car.

In general, the implementation of the proposed utility model will simplify and reduce the time servicing cars during operation, as well as increase the stability of a raised car due to the wider and more rigid construction of carriage 8 and beams 9, 10.
