Abstract

The invention relates to a lifting machinery industry, in particular to skip hoists, and can be used to lift small and loose goods, as well as to transport them horizontally and subsequent unloading into the bunker. The purpose of the invention is to increase reliability in operation. The skip hoist contains a drive 1, profile directions 2 and 2, on which skip 3 with a pusher 4 is installed, made movable by means of a flexible rod 5. In the skip 3 loading and unloading zone, directional switches 6 and 7 and weight sensors 15 are installed and 16. The skip shut-off unit 3 is a lever of the first kind, the axis of attachment of which is equidistant from its upper and lower walls. One of the arms 9 of the lever is permanently spring-loaded, and the other arm 11 is provided with a roller 12 and cooperates with the stop 13 of the dispensing hopper 14. The feeding hopper 17 has a gate 18 with a spring 19 and a hatch 20. On the rails 2 there are windows for mounting and dismounting the skip 3 The angle of inclination p of the discharge section exceeds the angle of repose of the material being transported. After loading the skip 3, the weight sensor 15 is activated, and when the drive 1 is turned on, skip 3 rises along the rails 2.

The invention relates to lifting and transporting mechanical engineering, in particular to ski BiBiM lifts, and can be used to lift small-piece and bulk cargoes, as well as to transport them horizontally and subsequent unloading into the bunker.

The purpose of the invention is to increase the reliability of ijocTn in operation.

j and figs. 1 shows a skip lift - Nick, general view; in fig. 2 is a view A of FIG. 1. I Skip hoist C supports drive 1, | Profiles 2, on which the skip 3 is fitted with the pusher 4, is designed to move through the flexible cable body 5. In the area of load and skip 3, the switches 6 are installed and 7

A spring-loaded shut-off unit of a skip 3 r | represents a lever of the first kind, the axis 8 of which is equidistant from the upper and lower walls of the skip 3, and one of the shoulders 9 of which constantly interacts with the spring 10, and the other arm 11 equipped with rollers 12, interacts with unloading with the stop 13 located on the dispensing hopper 14.

j In the area of unloading and unloading, additional weight sensors 15 and IJG for switching on the drive are set; they are set to act upon the action of the unloaded load. The feed hopper 17 is equipped with a shi-18 with a spring 19 and a hatch 20. On the steering 2 there are windows 21, the width of which exceeds the length of skip 3.; The angles a and J3 are determined from the condition of full unloading of the skip 3 and performed equal to the value.

The angle (B of the slope of the unloading section - | a must be greater than the angle of the natural I b slope of the transported material to ensure that the load is completely empty.

The device works as follows;

When skip 3 approaches the loading position, pusher 4 interacts with gate 18 of feed hopper 17, opening access to the transported cargo through hatch 20 into skip 3. At the same time, skip 3 interacts with switch 6, turning off drive 1. Skip 3 stops and download it goes. After the weight of the load dose reaches a certain value, the weight sensor 16, which is adjusted to this weight, is triggered and activates the drive 1 to lift skip 3 along guide rails 2.

Under the action of the spring 19, the gate 18 closes the supply of cargo. At the unloading position, skip 3, moving along an inclined guide angle p, interacts pojniKOM 12 of arm 11 with abutment 13 until skip 3 is fully opened. At this moment skip 3 acts on switch 7 and drive 1 is turned off. There is a unloading skip 3.

The execution of the arms 11 and 9 of the lever at an angle a, equal to the angle p, provides the most favorable conditions for unloading.

After unloading, the weight sensor 15, adjusted to the weight of the empty skip 3, turns on the drive 1 to feed it to the loading position. In this case, under the action of the spring 10, the lever with the arms 9 and II is rotated to the initial position.

Then the cycle repeats completely.

The skip 3 is mounted and dismounted by disconnecting it from the traction unit 5 on the horizontal section of the guides 2 through the windows 21 whose width is greater than the length of the skip.

Claims (2)

1. A skip hoist containing a drive, profile guides, on which a skip is mounted for movement by means of a traction body, having a spring-loaded shut-off unit, on which a roller is mounted, which is in contact with the skip mounted on the guides, and has a hopper and dispensing bin. installed, respectively, in the skip loading and unloading zone, and a limit switch for stopping the skip, located in the discharge zone, characterized in that, in order to increase operational reliability , it is equipped with skip weight sensors installed in the loading and unloading zone and a pusher mounted on the upper wall of the latter, capable of interacting with a spring-loaded gate valve of the feed hopper, while the locking assembly is a lever of the first kind, the fulcrum of which is equidistant from the upper and lower skip walls. 2. The elevator according to claim 1, characterized in that, for the purpose of ease of maintenance of the elevator when skip is removed, windows whose width exceeds the length of the skip are made in the guides.
