SU419472A1 - DEVICE FOR VERTICAL MOVEMENT OF OBJECT - Google Patents

Description

The invention relates to lifting means. In particular, to devices for the vertical movement of objects.

Devices for vertical movement of an object are known, containing spatial supports iB mounted on cross-beam columns and a rope-block system including open and closed lines and a power drive.

The purpose of the invention is to simplify the design and provide orientation of the object when lowering.

To do this, in the proposed device, the cable-block system is equipped with equalizing transitions, each of which is associated with open and closed lines, the disconnected strols are stored in the guide blocks and connected to the object, and the closed lines are stored in the group of guide blocks and connected with its middle part, formed in the form of a loop, with a ram of a power cylinder, while the free ends of the open lines and the middle part of the closed line are fixed by means of control clips.

In addition, the control clamp is made in the form of plates, which squeeze the sling by means of a bolt joint, in the gap between which the through-guiding and bending fingers are installed.

FIG. 1 shows a diagram of the proposed device; in fig. 2 shows the construction of a control clamp for slings; in fig. 3 is a section (BUT A-A 1 in Fig. 2.

The device contains two U-shaped rack 1 box-shaped. The elements of the cable block system are located inside beams 2, columns 3 and in box 4. Relocatable object 5, for example, the multi-electrode 44A1 electro-film automatic machine, is placed in between the racks 1. The cable-block system includes a closed sling 6 and two open lines 7. Each sling 7 is connected to stronome b by means of a balancing nerehodik 8. The power drive of the cable-block system is made in the form of a power cylinder 9, installed in Figure 4 and acting on the cable-block system by means of a pair of coaxial leveling

10 cushions fixed to the fork 11 of the rod 12 of the cylinder 9. The end bush 13 of the line 7 are attached to the base 14 feet 15 of the object 5, thanks to which the length of the end branches of the line 16 is maximized.

7, which facilitates the horizontal non-displacement of the illuminated object 5, i.e., it allows its orientation along a fixed product (step and tilt). The branches 16 of the sling 7 are thrown over the guides of the two-strand blocks 17, the loop 18 of the sling 7 covers

upper pitcher 19 of equalizing adapter 8. Coup 19, like other equalizing bushs 10 and 20 (lower pit ax of adapter 8), is made in the form of small blocks (in the form of bolted cores) with the possibility of rotation on the base line. Transition 8 consists of two forks with cushions connected by a base to each other. Koush 20 swivels in relation to koush 19 by 90 °. The final loops of the closed sling 6 encompass the thimbles 20 of the adapters 8, then go through the software group to the two-strand two-way units 21 and cover the loops 22 with a pair of tons of the best 10 drive units. Each equalizing collar (10, 19, 20) has a control clip 23. For the cushions 10, this clip is paired in a single package. Each clamp 23 has two plates 24, which compress the rope with a bolted joint 25, and through fingers 26 are installed in the gap between the plates (these can be shank), which guide and bend the rope as it passes through clamp 23. For each branch At least there are three fingers 26. Such a clamping device allows the rope clamping force to vary smoothly and allows partial slipping of the rope branches in clamp 23 when sampling irregularities in stretching of the individual branches of the rollers. Each plate 24 is provided with an elastic lining 25 for more uniform compression of the ropes and to prevent cross section deformations harmful to the ropes.

The rope-block system ensures uniform tension on all branches of the lines, setting the lengths of the lines without special tension mechanisms.

The device works as follows.

When installing or repairing, they adjust the length of the strons and ensure the gravity of the tension forces. For this purpose, the clips 23 are loosened, the object 5 is fixed in any correct position and the power cylinder 9 is turned on. When the hinges 22 are tensioned, all branches of the strolles are tensioned with equalizing tines 10, 19, 20. After all backlash sampling in the rope-block system, the control clips 23 are tightly clamped, fixing the reached position.

After that, the device is ready for operation. The object 5 is released, and when the power cylinder 9 is turned on, the thimbles 10 are moved to the left, the transitions 8 are lowered down, the thimbles 13 are in parallel raised upwards, the vertical object 5 is raised.

The device has a rigid fixation of the object 5 in the upper position. This is accomplished by the known non-driving gears or non-driving clips. The device also provides for changing the speed of movement of the object in the extreme areas of lifting and lowering the vehicle by means of track throttling, which is carried out by means of a special copier mounted on the fork 11 and directly acting on the pneumatic equipment (not shown).

For orientation when lowering, the aiBTOmat 44A1 is equipped with special wedge lugs (not shown) interacting with the edges of the product to be welded. In this interaction, the automaton smoothly deflects in the required direction and precisely aligns itself with the product.
