Abstract

FIELD: mechanical engineering; lifting and transporting equipment.

SUBSTANCE: invention relates to lifts with rack nuts. Proposed lift has nut made for all depth of building shaft or combination of racks and rollers with axes square to axis of rack, or projections arranged over screw line and screw connected with load platforms provided with support carriages with rollers for contacting with guide paths of nut racks with possibility of movement of screw in shaft along said nut. Lift is furnished with additional shafts with nuts made as those of main shaft and additional screws connected with load platforms with support carriages with guide paths of nut racks with possibility of movement of screw in corresponding shaft. Running wheels with drive secured on lower load platform of each screw are designed for moving along horizontal routes and getting into vertical shafts in upper and getting into vertical shafts in upper and power positions of screws. Cab is installed on upper load platform of each screw over which supporting paths are secured with cavities for fixing wheels of lower load platform of screw arranged higher in shaft.

Description

The invention relates to material handling equipment, in particular to elevators.

The purpose of the invention is to increase the productivity and reliability of transporting passengers and goods by supplying it with additional shafts and screws with platforms and ensuring that the screws with platforms go to the horizontal tracks and enter them from the horizontal tracks into the nuts of the vertical shafts in the upper and lower positions.

There are lifts with moving cabs fixed to a common traction unit: a rope, a chain, however, such lifts can only move cabs along a common closed route with a limited lifting height, and a common traction unit and a common drive of the entire device in case of malfunction and non-standard situations stop the whole device and such a stop may be most unfavorable for passengers. There are escalators for moving people in public buildings and the metro, however, these devices have disadvantages related to the disadvantages of elevators with a common flexible traction unit, in addition, escalators occupy large spaces and passengers can only get in and out of their passengers in the upper and lower positions, and they have speed limited by the ability to enter and exit passengers on the go.

There are hoists with roller nuts, for example 1486450 A1 and others, in the roller nuts of which the platform screws can be moved, however, these lifters do not provide screws with platforms from vertical shafts to horizontal tracks and entry from horizontal tracks to vertical shafts and therefore cannot the necessary time points to quickly move people or goods in the right direction, for example in the morning to workplaces, in the evening in the opposite direction and in the necessary direction in unusual situations, since e screws with platforms in each shaft with a roller nut without securing the release of screws with platforms on horizontal tracks can only be shuttle.

A hoist is proposed that comprises a nut made to the entire depth of the mine shaft of a building or structure from rods with rollers having axes perpendicular to the axis of the rail or protrusions located along a helical line, the rails being mounted on rings, and a screw connected to cargo platforms having supporting carts with rollers for contacting with the guide tracks of the nut rails with the possibility of moving the screw in the shaft along the said nut, characterized in that it is equipped with additional shafts with nuts, made in the same way as in the main shaft and additional screws connected to cargo platforms with support trolleys with rollers for contacting with guide rails of the nut rails with the possibility of moving the screw in the corresponding shaft, running wheels with a drive are fixed on the lower cargo area of each screw for moving along horizontal tracks and entering vertical the shafts in the upper and lower positions of the screws, on the upper cargo area of each screw a cabin is installed, over which support tracks with recesses are fixed for fixing and wheels of the lower cargo area of the screw located above the shaft, in the lower parts of the shafts under the nuts are recesses with nuts made similar to the nuts located in the shaft, other screws are installed in the nuts of the recesses, which are similar to moving in the shafts for receiving and sending the latter when lowering and raising .

The elevator comprises a nut mounted in each of several shafts from rails 19 having rollers with axes perpendicular to the axis of the rails or protrusions mounted along a helical line, and from rails 2 having guide tracks, screws 5 with platforms 4 can move in these nuts and 7, and on the lower platform 4, the running wheels 3 are mounted with a drive 22 for moving along horizontal tracks, and on the upper platform 7, cabs 20 are attached, over which the supporting tracks 21 with recesses 23 are mounted for fixing the wheels of the lower cargo area above set in the shafts of the screws, as well as drives 6 of rotation of the screw, support trolleys 8 with spring-loaded slides 17 having rollers 18 for contacting with the guide tracks of the rails 2, in the lower parts of the shafts under the nuts there are recesses 24 with nuts made similar to nuts located in mine, in the nuts of the recesses installed other screws 25, made similar to moving in the shafts for receiving and sending the latter when lowering and lifting.

The device operates in several ways as follows. An option when it is necessary to move people or goods from a lower position to an upper one, then the screws located in the lower part alternately go to the supporting tracks 21 of the screw located in the recess 24 and are fixed in the recesses 23 of the supporting track 21 by the wheels 3 and are lifted by this screw to screwing into the nut for the calculated number of turns, after which the lifted screw independently rises along the shaft nut with its drive, and the recess screw 24, dropping to the same level as the supporting track with the horizontal track movement, takes the next screw in each mine. The screw, which has moved to the upper position, waits for the next screw, which rests against the supporting road on the wheels above the existing screw and with the simultaneously rotating screws rise to rise until the supporting track below the existing screw meets the horizontal track. Above, the screw slides onto the horizontal track.

The next option. Move in reverse order in each mine.

The next option. The movement of the screws is carried out along continuous routes and along different routes of movement.
