Abstract

The invention relates to the construction, in particular to hoisting-and-transport mechanisms used for the production of concrete products in forms, for example, with vibration compaction of concrete. The purpose of the invention is to increase reliability. The lift has guides 1, made with gaps, the distances between which are equal to the distance between the rollers of the form 2 being installed on the lift. The hinged-lever systems 3 are located in the gaps of the guides 1 and are made in the form of levers hinged at the ends of the guides flush with their support surface and interconnected by means of a movable locking element, for example, an axis mounted on one of the levers, and the other lever is made with a longitudinal groove in which the locking element is placed. The hinged-lever systems 3, located on opposite guides 1, are connected in pairs by parallel-arranged synchronizing shafts. The actuator 9 is made with a pusher 10 equipped with rollers 11 in contact with the levers of the hinge-lever systems 3 of one of the guides 1. 5 Il.

The invention relates to the builder, namely to the lifting and transport mechanisms used for the production of concrete products in forms, for example, with vibrocompaction of concrete,

The purpose of the invention is to increase reliability.

FIG. 1 shows a lift with a form attached to it, a common view from the side; fig 2 is the same plan; in FIG. 3, node I in FIG. 1 (articulated lever systems are installed flush with the support surface of the guides); in fig. 4 is the same; the hinged-lever systems in the lowered position (the form is supported on the vibration set) j in FIG. 5 — node II in FIG. 2,

The lift consists of guides 1, made with gaps, the distances between which are equal to the distance between the rollers being installed on the lift of form 2, Hinge-lever systems 3 are located in the spaces of guides 1 and are filled in the form of levers 4 and 5, which are hinged at the ends of the guides flush with their supporting surface and interconnected by means of a movable locking element 6, for example, an axis mounted on the lever 4, and the lever 5 is made with a longitudinal groove 7 in which the locking element 6 is placed. ir-lever systems 3, located on opposite guides 1, are connected in pairs by parallel-arranged synchronizing shafts 8. A drive 9, for example, a hydraulic cylinder, is made with a pusher 10 equipped with rollers 11 in contact with levers 4 and 5 of a hinged-lever lever 1, 1x systems 3 one of the guides 1.

The elements 12 of the vibration settings are located under the bottom of the form 2.

The lift works as follows.

Form 2, filled with concrete, is set along guide rails 1 to the lever-lever systems 3. The drive 9 is switched on, under the action of which the pusher 10 with the rollers 1 1 fixed to it begins to move and takes the rollers out from under the hinge-lever systems 3, Under the form of the form1.1

2, the levers 4 and 5 are turned, and the locking element 6 is moved along the longitudinal groove 7. The hinged-lever systems 3, which are connected in pairs by the synchronizing shafts 8, are evenly lowered.

Form 2 can be fed to the pivot-mounted systems 3 without precise installation (within the lengths of the arms

4 and 3), as when lowering the form

2, the rollers of the mold roll to the center of the connection of the levers 4 and 5,

After lowering the levers 4 and 5, the working gap E is fully selected (Fig. 3) and the shape is set on the vibratory elements 12. Under its own weight, levers 4 and

They go slightly lower and come out of contact with the rollers of form 2. After this, form 2 is subjected to vibration, and then lifting of form 2 i

To do this, include the actuator 9, under the action of which the pusher 10 moves the levers 4 and 5 to the initial position, raise the shape 2 to the level of the bearings 1. Invention Formula An elevator for carrying out the trolley-shaped form, which contains the trolley-shaped trolleys installed on the base, performed with gaps, the spacing between which is equal to the distance between the rollers, the lugs of the trolley-form frame, the levers overlapping the gaps installed with them. the ability to rotate in vertical planes passing along the guides and connecting in the horizontal position between each other the limiting discontinuities of the guides, driving the levers, including moving p The faces interacting with the lower surfaces of the levers, and the pusher mounted on the base and associated with at least one roller, differing in that, in order to increase reliability, in each break two levers are mounted, connected by a hinge, whose axis mounted in one of the levers with the ability to move along it, and all the rollers are fixed on the pusher. w Thebes Fiel FIG. five
