Description

The invention relates to lifting transport devices and can be used for lifting small piece and bulk cargo and transporting it with unloading into the hoppers of process equipment.

A skip hoist containing a two-speed drive, guides, a trolley moving along the guides by means of a traction device, a skip mounted on the axis of the trolley with the possibility of rotation, equipped with a guide tray and levers with a roller interacting with an emphasis in the discharge zone 1 .

The disadvantage of this is the presence of one place of loading and unloading, which limits its scope.

Closest to the proposed technical essence and the achieved result is a skip hoist, including a cargo trolley with a skip and a track 2 that is hinged by means of axles.

The purpose of the invention is to ensure the safe movement of the skip along the vertical sections of the track.

This goal is achieved by the fact that in a skip hoist, including a cargo trolley with a skip and articulated pivot through axes and trails, the skip is provided with bristles mounted on its axis and a curved rail, and the cargo trolley is equipped with a gear wheel with a roller, while the gear wheel is engaged, and the roller is mounted in a curved guide, with the gear wheel and curved guide centers being offset relative to each other.

FIG. 1 shows a skip lift, front view; Fig 2 - truck trolley on a horizontal section; front view; in fig. 3 - cargo truck on a horizontal section, top view; in fig. 4 - cargo truck on a horizontal section, side view; in fig. 5 - cargo trolley on a vertical section, front view; in fig. 6 - cargo trolley at the time of unloading skip, front view; in fig. 7 - skip and locking mechanism on a horizontal section, front view; in fig. 8 - skip and locking mechanism on the vertical section, front view; in fig. 9 - skip and locking mechanism at the moment of skip unloading, front view.

The skip hoist contains a running path 1, a drive station 2, receiving hoppers 3, hoppers 4 for technological equipment, supports (retractable) 5 connected to the corners of electromagnets and installed at the points of discharge; traction unit 6, made in the form of two parallel vertically closed chains, pivotally connected with the cargo carriage 7, carrying the pivoting in the supports 8, mounted on the frame 9 of the cargo carriage 7, skip 10, the locking mechanism and the skip unloading mechanism. The mechanism for fixing the skip 10 contains a gear bristle 11 mounted on the skip and in contact with a gear wheel 12 mounted on the frame 9 of the cargo trolley 7. The gear wheel 12 is provided with a roller 13 mounted in a curved guide 14 mounted on the skip. The center of gravity of the skip 10 is shifted towards the fixation mechanism. Skip 10 is in a horizontal position, since the radii of rotation of roller 13 relative to axis 5 of gear wheel 12 and curved guide 14 relative to axis of skip 10 are different.

The skip unloading mechanism 10 comprises a gear rail 16 which is spring-loaded in the axial direction 15, mounted in rails 17 mounted on the frame 9 and in contact with the gear bar 18 mounted on the skip 10.

I

The trolley 7 by means of the support rollers 19 fixed on the frame 9 is mounted on the running track 1, and the link of the traction device 6 (chain) is fixed pivotally with respect to the frame 9 and coaxially with respect to the front support rollers 19 of the cargo trolley 7.

0 Skip lift works as follows.

The trolley 7 is in its initial position in the lower horizontal section of the track. When performing any of the receiving bins 3, the products are given a command (sensors controlling the operation of the receiver, not shown) to the drive station 2, which, in this case, starts the movement of the traction body 6 of the cargo carriage 7, and the last

0 moves towards the receiving hopper 3. When the cargo trolley 7 reaches the receiving hopper 3, the drive station 2 is turned off and the skip 10 of the cargo trolley 7 is loaded with products from above. When reducing the level of products in any of the bins 4 for technological equipment, a command is sent to the drive station 2 and the electromagnet of the withdrawable stop 5 corresponding to the bunker, while the drive station 2 is turned on, the traction unit 6 starts moving and the stop 5 extends corresponding to the bunker 4. Freight the carriage 7 moves towards the bunker 4 along the lower portion (horizontal) of the running track 1.

When the truck trolley 7 reaches the turning point of the runway 1, its front support rollers 19, rolling in them, unfold the frame 9 by 90 °. At the same time, the gear wheel 12 runs around the gear gear 11; The roller 13 of the gear wheel 12 rolls around in the curved guide 14 and, due to an increase in the radius of the curved guide at each of its points relative to the axis of rotation of the skip 10, the skip 10 remains in a horizontal position. A pinioned brush 18, fixed on the skip 10 and in contact with the rack 16, moves the latter in the guides 17 towards the movement of the load trolley 7. The load trolley 7 moves along the vertical section of the track 1 of the skip hoist. When it reaches the turning section of the running track 1, the front support rollers 19 of it, rolling in them, turn the frame 9 by 90 ° in the opposite direction. At the same time, the roller 13 of the gear wheel 12, rolling in the curved guide 14 of the skip 10 in the opposite direction, is horizontal in the horizontal position, and the gear gear 18 moves the gear rack 16 in the guides 17 in the opposite direction relative to the direction of movement of the load carriage 7. moves along the upper section of the track 1 of the skip lift, while the rack 16 interacts with the retractable stop 5. Upon further movement of the trolley 7, the frame 9 moves relative to the fixed with the support 5 in a stationary position of the rack 16, with the latter turning the gear jaw 18, and the skip 10 tilting in its supports 8, while the gear gear 11 rotates the gear 12 clockwise, the roller 13 of which goes out of the curvilinear guide 14 of the skip 10. Unloading takes place and the products are poured from skip 10 into the hopper 4 of the process equipment. After unloading the skip 10, the command of the drive station 2 is given to the reverse carriage 7 and, to the electromagnet of the abutment 5. The stop 5 returns to its original position, the cargo carriage 7 moves in the direction of loading, and the rack rail 16 returns to its original position, turning the gear bristle 18, the skip 10 turns in the supports 8 to a horizontal position, the gear gear 11 rotates the gear 12 counterclockwise, the roller 13 of which returns to the curvilinear guide 14, and phi xsatsi skip 10. Next, the load carriage 7, the upper horizontal and vertical sections of the travel track 1, return to their initial position along its lower horizontal section, and the drive station 2 is turned off. Then the cycle of operation of the cargo carriage 7 of the skip hoist is repeated. The proposed skip hoist is not complicated in design, reliable and convenient in operation and, as having advanced technological capabilities, can replace two or more well-known skip hoists, as a result of which the cost of manufacturing and repair during maintenance of the device is reduced, and also the losses from transportation as a result of reduced transshipment operations.
