The purpose of the invention is to increase the reliability of the device when transferring stacked shields of various sizes. Between the feeding roller (P) located at different levels and the receiving P 32, there is a vertically movable perp: I

Description

one

The invention relates to a lifting machinery and can be used for lifting and reloading of axial loads between roller conveyors installed at different levels.

The aim of the invention is to increase the reliability of the device when transferring stacked shields of various sizes.

FIG. 1 depicts the proposed-. my device, a general view; in FIG. 2 then f, e, side view, in FIG. 3 - combined live rolls; in fig. 4 - the same top view; in fig. 5 is a diagram of the braking mechanism; in fig. 6 - fork-shaped pusher.

Lifting and reloading device contains a feed roller conveyor 1, a non-driving roller conveyor 2 with an abutment wall 3 and rollers 4 mounted on racks 5, and a drive transmission roller table 6 with driven rollers 7, driven by a gear motor 8 via chain drives 9 and 10,

The lifting unit has a fixed welded base 1I, a drive in the form of a hydraulic cylinder 12 connected to a lifting crosspiece 13, a distributor 14 with a control handle 15, two contacting sliding frames 16 and 17, draw chains 18 and 19, rollers 20 and 21

The braking mechanism includes a housing 22, a rod 23 with a fork

a cathele 24, secured with a locknut 25, a roller 26 and a spring 27.

The lifting yoke 13 carries a fixed braking jig 28 and a transfer roller conveyor 6 s) with a limit switching lever 29. Spring dampers 30 in the housings 31 are mounted on the base 11. The receiving roller 32 is located above the level of the feeding conveyor and the limit switch 33 is fixed to its base. The drive station of the hydraulic cylinder 12 is not shown.

The upper level of the rollers 7 of the transfer roller table 6 in the horizontal plane is set 5 mm below the rollers 4 of the non-driving roller table 2 located at the level of the feeding conveyor I.

The jig 28 is made of angle number 5, the working side of it is mounted at an angle of 92 to the horizontal plane.

The device works as follows.

A load 34, for example, a stack of shields from the roller table is moved to roller table 2 to stop wall 3. Using the handle 15 of the control valve 14, set to the Up position, the hydraulic cylinder 1-2 is activated and the traverse 13 moves upwards through the contacting sliding frames 16 and 17, t beef chains 18 and 19 and rollers 20 and 21. Transfer roller conveyor 6,

rigidly connected to the lifting beam 13, begins to rise and the rollers 7 pick up the load 34 from rollers., 4 fixed roller table 2 and move up to meet the lever 29 with the limit switch 33, which turns off the electric drive of the hydraulic cylinder 12 and simultaneously turns on the gearmotor 8. The rollers 7 of the transfer roller table 6 begin to rotate, the load 34 moves to the roller table 32.

Using the handle 15 of the control valve 14, the transfer roller 6 descends. Lowering is done by its own weight; accurate roller table 6, resting on the hydraulic cushion formed by the bypass hole of the distributor 14, when the handle 15 is set to the Down position. - To reduce the impact of the descending yoke 13, which is rigidly connected to the transfer roller 6, on the base 11, spring shock absorbers 30 and braking mechanism assembled in housing 22 are mounted in the housing 31. The braking is carried out by uniformly pressing the pusher 24 on the control handle 15, with which the overflow port of the distributor 14 gradually overlaps. Smooth deceleration is provided by a jig 28 mounted vertically with the inclination of the working path in contact with the roller 26 at an angle of 92. The roller 26 returns n is a spring 27, clad on the rod 23. The forked pusher 24 is secured by threaded compounds

to the rod 23, which allows you to adjust the reliability of braking. A fixed length of the pusher 24 is locked 25.
