Abstract

The invention relates to garage equipment, in particular to means for servicing automobiles. The purpose of the invention is the improvement of maneuverability. The device comprises rotary wheels mounted on the platform by means of axles with forks, outriggers and trolley guides, and a power lift with grippers for the aggregates. The forks of the swivel wheels of each side are connected by longitudinal arms pivotally to each other by a spring-loaded transverse link with longitudinal arms. In the middle part of the platform, the lever of rotation with a folding handle is installed by means of a vertical axis; it is pivotally connected at one end to the middle part of the transverse rod. 6 Il.

Description

This invention relates to lifting devices.

The purpose of the invention is to improve the maneuverability qualities of a lifting trolley.

Figure 1 shows the device, the overall appearance, figure 2 is the same, top view; on fig.Z - view along arrow A in figure 1; figure 4 - section bb in fig.Z; on fig.Z - section bb In fig.Z; figure 6 - drive lift. The steering device with a lifting trolley consists of a frame 1, a trolley 2 with rollers 3, rolling along the guides 4 of the frame 1. At the ends of the frame 1 are mounted bushings 5, and in them - axis 6 with swivel forks 7, carrying wheels 8. Longitudinal levers 9 the rotary forks 7 are the hinged axles 10 connected to the extended consoles 11 of the transverse thrust 12. In the middle part of the transverse thrust 12 there is fixed a longitudinal console 13, which is articulated through the axis 14 to the swivel lever 15, which is installed flax on the axis 16 mounted on the frame 1. The lever 15 is provided with a folding handle 17. On the sleeve 5 of the frame 1 outrigers are mounted 18. Transverse to t 10

The frame 1 was out of the car area.

When maneuvering by turning the arms 17, the lever 15 is rotated. In this case, the transverse thrust 12 is shifted through the arms 11 of the axis 10 and the longitudinal arms 9 rotates the forks 7 with the wheels 8 by the corresponding angle.

For a stable position, the outriggers 18 are divorced and set against the floor.

Moving the trolley 2 and lifting the nick 20, the grippers 34 are brought under the descendable unit. The pedal 29 performs lifting of the telescopic element 33 of the jack 24. In this case, the pedal 29 is set to the extreme left position so that the rightmost cut rests on the finger 32. With this, the pedal 29 stroke is minimum, and the plunger 28 stroke is maximum. This achieves an increase in idle performance. When lifting the unit, the pedal 29 is shifted to the finger by the middle or leftmost cutout, thereby changing the ratio of the shoulders relative to the finger 32. The rod stroke decreases and the pedal stroke increases.

On the trolley 2, a power lift 20 is mounted, which is an oil tank 21 equipped with rollers 22 mounted in guides 23, and a hydraulic telescopic jack 24 with a foot plunger drive 25.

The plunger actuator includes a lever 26, a hinge 27 attached to the plunger 28, and a pedal 29, the hinge 30 connected to the lever 26. Pedal 29 has cutouts 31 under its finger 32 of the plunger rod 28.

On the telescopic element 33 of the jack 24 is installed easily removable device - grips 34 for removal and installation of the units of the car.

Under the car, which is hung out on the floor garage lift or on stands, the device by the folding handle 17 rolls under the removable unit so that the second one. - p-o10

The frame 1 was out of the car area.

When maneuvering the rotation of the handle 17, the lever 15 is rotated. At the same time, the transverse thrust 12, shifting through the arms 11 of the axis 10 and the longitudinal arms 9 rotates the forks 7 with the wheels 8 by an appropriate angle.

For a stable position, the outriggers device 18 is diluted and rests against the floor.

Moving the trolley 2 and the lift 20, the grippers 34 are brought under the detachable unit. The pedal 29 lifts the telescopic element 33 of the jack 24. At the same time, the pedal 29 is set to the extreme left position so that the rightmost cutout rests on the finger 32. At the same time, the pedal 29 stroke is minimal and the stroke of the plunger 28 is maximum. This achieves an increase in idling performance. When the machine is raised, the pedal 29 is swapped by the middle or leftmost cut-out on the finger 32, thereby changing the ratio of the shoulders relative to the finger 32. The stroke of the rod decreases and the pedal stroke increases.
