Description

(54) STEP CONVEYOR

The invention relates to a lifting and transport technology, namely, step conveyors. A step conveyor is known, consisting of a lower chassis, supported by its rollers on a rail track mounted on a foundation, and an upper support part in the form of a beam. In addition to running rollers, the lower chassis is also equipped with supporting rollers 1. The presence of supporting rollers complicates the chassis design significantly, increases the height of the conveyor and increases the intensity of the conveyor. The closest technical solution known is a stepping conveyor comprising a movable base, a supporting frame placed on a fixed base, a movable frame in the form of a beam with pushers mounted on a supporting frame, connected with a reciprocating drive. The support frame is made in the form of two rows of rollers mounted on a fixed base by means of brackets on horizontal axes. When the beam is moved, the rollers, rotating, remain in place 2. The design of this support frame is quite bulky. In addition, it does not reduce the effort required to move the conveyor. These drawbacks reduce the performance of the conveyor. The purpose of the invention is to increase the performance of the conveyor. This goal is achieved by the fact that, in the proposed conveyor, the support frame is made in the form of a movable section of the roller table, the ends of which are connected to the ends of the beam by means of flexible connections. FIG. 1 shows a conveyor belt, longitudinal section; in fig. 2 - the same plan view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2; in fig. 5 shows a section B-B in FIG. 2. The stepping conveyor consists of a movable beam 1 with stops 2, located under one of the wheels of the movable product 3, fixed stops 4, located under a different row of wheels of the movable products 3, support frame 5, made in the form of a movable section of the roller table with rollers 6 with the help of which it moves along the tracks of the non-ported base 7 and the movement mechanism 8, made in the form of a hydraulic or pneumatic cylinder, which is connected to the movable beam 1 with the help of fingers 9. The beam 1 rests on the rollers 6 of the support frame 5. Ends supports th frame 5 connected with the ends of the beam 1 flexible linkages 10 and 11 that provide remote assigning a lower chassis 5 relative to the beam 1. The conveyor operates as follows. The movable product 3 under its own motion with the front wheels moves through the stop 2 of the movable beam 1 and stops before the stop 2. After this, the movement mechanism 8 is turned on, the stop 2 rests on the wheel of the product 3 and the product 3 moves together with the beam 1 by one work clamp to the position the stop 2 of the upper beam 1 will reach the line of the fixed stop 4 located under another row of wheels of the product 3. In this case, the support frame 5 with the help of rollers 6, interacting simultaneously with the beam 1 and the rail tracks 7, will move in the same way in the same way as beam 1, and the flexible link 11, which was tensioned before moving the conveyor forward, will move in the process of moving the beam 1, and the flexible link 10 will pull, and at the end of the forward movement the flexible link 11 will fold , and the flexible bond 10 is tensioned. After the process of moving the product 3 forward, the conveyor stops and the 8% displacement mechanism starts moving the beam 1 back to its original position, while the wheel of the product 3 abuts against the fixed stop 4 and remains in place, and the beam 1 moves back to its original position, scrolling the wheels products 3 standing on it. The lower part 5 at the same time is the II I f,

It also moves in the same direction. as beam 1, and at the end of the backward movement, the bond 10 is folded, and the link 11 is tensioned. Thereafter, the moving process is completed and the conveyor takes up its original position. Due to the fact that the supporting rollers simultaneously interact with the railways and the load-carrying beam, it is possible to reduce the efforts required to move the conveyor, since in this case the shoulder increases by 2 times, by which the running gear rollers are scrolled. Connecting the ends of the lower chassis with the ends of the upper movable beam using flexible links allows you to reduce the length of the lower chassis, reduce its size and intensity, and ensure the orientation of the lower chassis relative to the front end of the upper beam. Claims of the Invention A stepper conveyor comprising a fixed base, a supporting frame placed on a fixed base, a movable frame in the form of a beam with pushers mounted on the supporting frame, connected with a return-translation movement, characterized in that the support frame is made in the form of a movable section of the roller table, the ends of which are connected to the ends of the beam by means of flexible links.
