Description

one

The invention relates to the field of construction and can be used in the production of works within the knowledge of industrial purposes for the distribution and finishing of coatings from concrete.

A device for leveling a concrete mix according to the main ed. St. No. 541915, containing a composite boom made up of sections connected by a hinge with a vertical axis and a leveling device in the form of a sealing arm, which is rotatable in the mountains of the iontaly plane. a plate on which a vibrator is mounted and a cylindrical closed shell with outer radial ribs evenly distributed around the perimeter.

The design of this device does not allow for the initial laying of the concrete mix, it is sufficiently efficient to distribute, since during transportation of the concrete mix to the place of installation it is partially self-compacting, and also provides the possibility of smoothing the surface of the laid coating.

The purpose of the present invention is to eliminate these drawbacks by increasing the efficiency of the work and by making it possible to smooth the surface of the laid mixture.

The goal is achieved by the fact that the device for leveling the concrete mix according to the ed. St. No. 541915 is equipped with a mechanism for the closure of the end section of the boom, which is made in the form of a hinge rod, which is pivotally in the vertical plane of the front and horizontally

A section with 1 rear arm brackets mounted on the boom end section, to the first of which a leveling device is rigidly attached, equipped with a rotation mechanism, with one end connected to the rear bracket and the other to the front bracket, and the horizontal boom rotation mechanism is in form of hydraulic cylinders placed on both sides of the sequence.

FIG. 1 shows a general view of a device for leveling a concrete mix; in fig. 2 is a general view of a screeding device.

The device for leveling concrete mix, mounted on the chassis of the base machine, consists of a column 1 fixed to it, to which is attached a bracket 2 with a vertical movement mechanism in the form of a power cylinder 3. A bracket 2 with a vertical axis is attached to the bracket 4 with a vertical axis from the support section 5 and section 6 connected by a hinge 7 with a vertical axis, with the axes of the hinges 4 and 7 parallel to each other. Section 6 is also made of a composite of a vertically rotatable front bracket 8, a horizontally rotatable back bracket support section 5 of the rear bracket 9, and an end section 10. On the rear bracket 9, the vertical axis of the hinge 7 is fixed and the tilt mechanism of the end section 10 is mounted in the form of a power cylinder II and a hinge cable 12, connected at one end to the rear 9, and the other to the front 8 arms, which, in particular, constitute, together with the end section 10, the hinge parallelogram. The end section 10 is rigidly connected with a leveling device consisting of a cylindrical closed shell 13, supported by means of a sealing ring 14 and shock absorbers 15 on a vibrating plate 16, with a vibrator 17, the outer radial ribs 18 being uniformly attached to the shell 13 is attached rigidly from above, the gear wheel 19 of the rotation mechanism of the screeding device, which engages with the necklace 20 mounted on the shaft of the engine 21 mounted on the bracket 22 rigidly connected bracket 8. On the bracket 22, the central axis 23 of the leveling device is fixed, on which the case 24 of the support brackets supported in the shell 13 is supported. On top of the axis 23 is mounted. G collector 25 for supplying the vibrator 17. The axis of the hinge 7 is connected to The rotational drive of section 6 in the form of a hydraulic motor 26 and the axis of the shaft 4 is provided with a rotation drive in the form of power cylinders 27 placed on both sides of the boom support section 5. The engine 21 of the scrolling gear rotation mechanism; self-braking is available, and the power cylinders of the dozer blade, outboard supports of the masking machine and the cylinders 3, II, 27, and the engine 26 are equipped with hydraulic locks for fixing the set position of the boom and leveling tool. To install the device in a predetermined position, a level 28 is provided, which is rigidly fixed to the bracket 2. The device for smoothing concrete mix works as follows. A base machine with a mounted concrete leveling device pulls up to a pile of concrete mixture unloaded onto the site. Controlling the hydraulic cylinders of the bulldozer blade, outriggers and power cylinder 3, the operator adjusts the position of the base machine and the hinged device to the levels and level, 28 so that the vibrating plate 16 of the leveling device moves parallel to the surface plane. Then, controlling the turning mechanisms 26 and 27, the operator moves the leveling device, distributing the concrete mix to the site. If the concrete mixture is partially compacted during transportation to the site, the operator switches on the rotation of the leveling device with respect to the central axis 23, which will then loosen the compacted mixture with ribs 18 and then, without rotation, distribute the concrete grain to the area. When distributing the concrete mix, a vibrator 17 is included, which intensifies the process of compacting the concrete mix. After distribution and compaction of the laid mixture, the surface of the laid coating is applied / lamination, for which purpose the motor 21 of the rotation mechanism of the spreading layer 16 is turned on by the engine 21 to ensure the surface finish of the coatings. Due to the possibility of rotation support-; Section 5 at an angle of 180 ° and turning the end section 6, a screeding device. Can spread the concrete mix to almost any point of the arbitrary confinement area where equipment or standing columns supporting construction trusses can be installed, shut off, etc. The concrete leveling device permits work to be performed both on open free areas and inside production areas with a given floor slope. The invention The device for leveling concrete mix according to ed. St. No. 541915, characterized in that, in order to increase the operating efficiency and enable smoothing of the surface of the laid mixture, it is equipped with a tilt mechanism for the end section of the boom, made in the form of a hinge rod, rotatable in the vertical plane of the front and horizontally rotatable relative to the supporting section of the boom rear brackets mounted on the end section of the boom, the first of which is rigidly attached to the leveling device, equipped with a rotation mechanism, with the traction of one end of Nena with rear bracket, the other - to the front, and iehanizm horizontal rotation arrows executed in the form of hydraulic cylinders placed at .obe side of the latter.
