The invention relates to construction equipment and can be used in the construction of multi-storey industrial and civil buildings for the supply of sheet weights to the floors of construction sites.

The purpose of the invention is to reduce the labor intensity of loading and unloading.

The conveyor elevator contains a spatial mast 1, which is fastened to building 2 by elements 3. At the top of the mast there is a tension station 4, below the drive station 5, on shafts 6 of which two blocks 7 are fixed. A cable 8 passes through them, the ends of which are connected After a certain distance, the load-carrying elements 9 are fixed on the cable, the position of which is fixed by limiters 10 fixed on the mast along its entire height. A loading unit is mounted at the base of the mast and the automatic installation of sheets into the mast The transport position and consisting of a parabolic base 11 of the feed shaft 12 with ribs 13, connected by a chain drive to the drive wheel 14, mounted on the shaft 6 of the drive station, the movable stop 15 with spring devices 16, the return bolt 17 of the stop with the steering wheel 18. In addition, there are levers 19 for transferring the sheet to the transport position with a ratchet 20. When transporting, the sheets rest on the load-carrying elements 9 with the lower end, and the upper end slides along the rails and 21, wearing plastic straps 22 on them. t is inclined at an angle of 15 ° from vertical at the length of the sheet 3 MI angle 18 with sheet length 2.5 m.

The exclusion of atmospheric effects on the sheets during their transportation, the lift mast has a continuous fence on three sides along its entire height. The side of the lift is not fenced, facing the building building.

At the level of the floor (addressee), removable areas are removed in the runway x 21 and the receiving balancer 23 is installed, which rotates on the hinge 24, with the hinge positioned so that the right shoulder of the platform is larger than the left. The plane of the receiving platform is a roller conveyor with rubberized rollers 25, and sides 26 are welded along the edges of the platform. Rotation of the balancing platform from the initial position B to the final C is carried out when the element 9 of the slider 27 moving along the guide 28 is hooked to 29, passing a mast shotgun and connected through a system of blocks to the platform 23. From the balance sheet, the sheet is placed on the self-loading trolley 30.

Conveyor lift works as follows.

The stack of cargo sheets is installed vertically by the forklift on the parabolic base 1 of the loading unit, resting on an inclination on the stop 15, translated by the bolt 17 and the steering wheel 18 to the extreme right position while the device springs 16 are compressed. the upper ends of the sheets are worn with brackets 22, and the steering wheel 18 releases the springs 16 of the device. The lift is ready to go. The drive station is turned on, the cable 8 with elements 9 fixed on it begins to move. At the same time, the feed shaft 12 begins to rotate, which with ribs 13 picks up the lower end of the first sheet and rearranges it to point 1 located on the line of motion of elements 9, while the levers 19 with the ratchet 20 engage the sheet. Being above the point G, at the moment of the sheet permutation, the load-carrying element 9 touches the lever arm 19 and as it moves upwards turns the levers clockwise, the levers 19, engaged with the sheet, deflect its translation through the vertical position

until the upper end comes into contact with the runners 21. At the moment of transfer of the sheet to the transport position, elements 9 come to the bottom of its end, pick up the sheet and move it upwards. With the ribs 13, the shaft 12 grips the next sheet and transfers its lower end to the point G. At the same time, the levers 19 come out of the engagement with the elements 9 and the springs return to their original position, while the ratchet 20 engages the next sheet. As the number of sheets decreases, based on

running position. At this point, there is another sheet on the way, the cycle is repeated.

In order for the load-carrying elements 9 not to come into contact with the pia3rpy3O4 platform, they have a hinge and, when they are moving downwards, they are folded upside down.

Formula image shadow Conveyor hoist mainly for sheet building materials, containing a mast, is attached 20 11, an emphasis 15 by the force of a spring-mounted device, j5 Y, towards the constructional building, infinity 16, moves the remaining sheets to the shaft 12. The distance between the elements 9 is assumed on the basis that the next sheet is transferred by the levers 19 through the vertical, when the previous element 9 is from point B at a distance greater than the length of the sheet. In addition, the gear ratio of the drive shaft 12 is set from the condition that the next sheet is transferred by the ribs 13 to the initial point T after the previous sheet goes up by 0.5 m. When the sheet approaches the floor - the addressee, the upper 25 a traction body covering the bars of the drive and tension stations, load-carrying elements, hinged on the traction body, lower, loading, and upper, unloading devices, in order to reduce the labor intensity of loading and unloading, t The gov body is made of two branches on which the load-carrying elements are located in pairs opposite each other, located in the transport position on the same horizontal line, while the loading device contains a parabolic base with a sub-spring nennym movable abutment ,, feed shaft kinematically associated drive station, and the double-arm levers transfer the cargo to the transport position, one arm of each of which could interact with gruzonesuschkm elements and the other through church povikov - with established on the basis of the load, the discharge mouth the edge sliding along the runner passes from them to the rollers 25 of the balancing platform 23. At the same time, the load-carrying element 9 engages with the slider 27 and, moving it up and pulling the cable 29, rotates the platform around the axis, while the angle of inclination the platform strictly corresponds to the angle of inclination of the sheet, which the second gradually approaches to the platform. Rotation of the platform stops at position B, and due to its inclination, the sheet rolls along the rollers 25 inside the building onto a self-loading trolley 30, where it is automatically placed in a pack. The position of the site 23 is appropriate  The moment when the slider 27, moving to the guide 28, deflects and exits, is released from the engagement with the load-carrying element 9.
