Description

one

The invention relates to the construction and can be used for laying and compacting concrete mixtures during the construction of dams, monolithic foundations and bridge supports.

A device for compacting concrete mixtures, mainly in an array, containing immersion vibrators mounted by means of a hinged traverse mounted on a traverse connected by means of a hinged-lever drive system with a self-propelled engine and a disadvantage of this device, is a low maneuverability and the impossibility of working through the concrete mixture in any point of a concrete mass.

The purpose of the invention is to mechanize the processes of laying and compacting concrete mixtures to reduce energy consumption and reduce time.

This goal is achieved by the fact that the device for compacting concrete mixes, mainly in arrays, contains immersion vibrators mounted by means of a hinged suspension on a traverse connected by means of a hinged-lever drive system with self-propelled bearing, equipped with a platform installed on the last horizontal turning station toroidm of step of deep vibrators, the traverse is made with a turning mechanism relative to vertical

5 axles, and the articulated drive system is in the form of a telescopic boom with a sliding cylinder placed in its cavity, which is pivotally connected to the lower end with a turntable.

In addition, the immersion vibrators are interconnected in pairs using horizontal pivot bolts, and the regulator of the vibrator of the immersion vibrators is arranged as a traverse of the power cylinder placed along the vertical axis, the body of which is rigidly connected by means of symmetrical levers fixed on the traverse.

20 mainly in arrays, a general view; FIG. 2 - the same plan view; in fig. 3 - the same, side view; in fig. 4 is a view A of FIG. one; in fig. 5 is a layout diagram of the depth vibrators with a minimum pitch; in fig. 6 is a section BB in FIG. 2; in fig. 7B-B in FIG. 6. A device for compacting concrete, mainly in arrays, consists of a self-propelled chassis 1 with a platform 2 rotatable in a horizontal plane, on which the lower section 4 of a telescopic boom is mounted with a hinge 3, inside of which is placed a sliding cylinder 5 in its cavity. The upper section 6 of the telescopic boom is connected by means of a turn actuator 7 with a crossbeam 8, to which, by means of a hinged lever suspension 9, immersion vibrators 10 are attached, locked in pairs using horizontal tg 11, each pair of immersion vibrators 10 connected by symmetrically located levers 12 sec. located along the axis of symmetry of the cross beam 8 by a power cylinder 13, the brush 14 of which is rigidly fixed on the cross bar 8. The mechanism 7 of turning the cross bar relative to its vertical axis consists of the power cylinders in 15 fixed in the cavity of the upper section b of the telescopic boom, the rods of which are connected kinematically with an asterisk 17 by means of a chain 16, and the bearings 18 of the axis 19 the asterisk 17 are placed in the housing 20 attached to the front end of the upper section 6 of the telescopic boom, and the axis 19 rigidly fixed to the crosspiece 8. Sections 4 and 6 of the telescopic boom are in contact with each other by means of guide rollers 21 fixed to the lower section 4 on both sides of section b, the rear end of the lower section 4 being pivotally connected to the power cylinder shaft 22 An inclined tee of a telescopic boom in a vertical plane mounted on a turntable 2. A device for compacting concrete, mainly in arrays, works as follows. After unloading the concrete mix from the bucket into the concreting unit, the operator from the control panel deploys the turntable 2 so that the telescopic boom with the cross member 8, equipped with immersion vibrators 10, is placed above the concrete mass fed into the unit, while using vibrators 10, the vibrators 10 are mounted on min. distance from each other. After that, the vibrators are turned on and with the help of the rod 22 of the power cylinder 23 change the inclination of the telescopic boom, while the vibrators are immersed in the newly loaded concrete mass. As the concrete mass is distributed on the surface of the array, the vibrators' spacing increases. Claim 1. Device for compacting concrete mixtures mainly in an array containing deep vibrators mounted by means of an articulated suspension on a traverse connected by means of a hinged-lever drive system with a self-propelled chassis, characterized in that in order to mechanize the processes of laying and compacting concrete mixtures , reducing energy consumption and reducing time, it is equipped with a turntable installed on the self-propelled chassis and a pitch regulator of vibrators, the traverse being made from th rotation about a vertical axis, and the toggle drive system - in the form of a telescopic boom placed in its cavity razdvizhki power cylinder, is pivotally connected with the lower end of the rotary platform. 2. The device according to claim 1, characterized in that the immersion vibrators are interlocked in pairs by means of horizontal hinges, and the pitch regulator of the immersion vibrators is made in the form of a traverse of the power cylinder placed along the vertical axis, the body of which is symmetrically connected to each pair by means of symmetrical levers vibrators, and the power cylinder shaft is rigidly fixed on the traverse.
