Abstract

Drive for a on a laser plate (1/6) movably mounted load-receiving device of a vertical lift provided with a planetary gear via recesses or support pieces 2 cooperates. characterized in that the support rollers 3 of a tilted, for example, 20 ° epicyclic gear 1 for example, immerse in recesses 1 and interact with or without support pieces 2 together.

Description

vertical lifts primarily for the transport of disabled people or vertical lifts for retrofitting into older ones Buildings are equipped with a drive for lack of space, which is located on the load handling device.

One special machine room for a winch or a Hydraulic unit are not required here.

Of the Drive takes place through motor-driven spindles, toothed racks, drive sticks etc. or by friction (traction).

These Drives are often very agile, expensive or need a lot of space, the free space for the load-carrying means reduced.

By the German patent DE 3602770 C2 and by that Utility Model No. 20 2009 009 573.8 is already known a drive in which support rollers act by means of a planetary gear on support rods and move the load-carrying means along an upper and lower guide Holmes at an angle <75 °.

So far Despite numerous attempts, it has not succeeded in this circulation drive also inexpensive and vigorous for vertical use.

The invention has for its object to provide a manufacturing technology simpler, smoother, space-saving and safer solution to be found using the in the Utility Model Application 20 2009 573.8 circulating drive described in a vertical lift.

These Task is with the listed in the protection claims Characteristics solved.

Embodiments of the invention will be described with reference to FIGS 1 - 7 explained. Show it:

1 from the Utility Model Application 20 2009 573.8 known circulation drive as a side view of 2

2 a diagram of the engagement of the idlers 3 in a laser sheet part 1 .

3 a diagram of the engagement of the idlers 3 in bolted support pieces 2 .

4 the interaction of the drive with a load handling device 11 .

5 the ground 11a of the lifting device with the possible accesses,

6 from the Utility Model Application 20 2009 573.8 known circulation drive as a side view of 3

7 an enlargement of the left load handler guide of 5 ,

The vertical lift consists of a circulation drive 8th including safety gear 7 with a geared motor 9 , a load handling device 11 with upper and lower guide shoes 13 , the suspension 1.6 , the ironing 12 for wall or scaffold attachment, the reinforcement angles 14 , Safety gear 7 , Emergency lowering handwheel 20 and commanders 10 ,

The shape of laser part 1 is given by the entry and exit of the idlers 3 , wherein only the middle part of each recess corresponding to the width of the support pieces 2 Is loaded without torque.

A slight curvature of the support pieces 2 or the middle part of the recesses in the laser part 1 allows a clean and quiet load transfer by the following carrying roles 3 ,

The temples 12 are on a wall at regular intervals 17 or any scaffold attached and are over the angles 14 with laser part 1 or laser part 6 connected by screws, with the recesses in laser part 1 also serve as a passage for wall drilling and fixing the wall plug screws.

When using laser part 1 low wall thickness become supporting pieces 2 using carriage bolts with laser part 1 connected. Alternatively, when attached to, for example, a scaffold laser part 6 without recesses with support pieces 2 be screwed.

The accesses to the load handling device 11 in 5 are arbitrary.
