Description

The invention relates to the fabrication of reinforced concrete products and can be used for the manufacture of welded volume mx frames for reinforcing jello-3eTOHfHjix rectangular sections, such as piles, columns, supports, etc.

A known apparatus for welding closed rectangular frames, comprising a winding faceplate with a jig through which longitudinal reinforcement bars pass, a movable faceplate, to which ends of the reinforcement are secured, moving with a hydraulic jack along the guides of the frame. As the longitudinal rods advance, spiral winding is produced and the wire is welded to the longitudinal rods; |.

The disadvantage of the installation is the impossibility of high-quality manufacturing of products due to the deflection of the welded frame.

Also known machine for welding ar.magurnyh frameworks of concrete products. This machine contains a plan with a jig connected to the spindle of the undercarriage by a synchronizing shaft installed in the sliding supports. The slide of the support hinge is rigidly connected with each other and installed on both sides of the trolley with the possibility of free movement under the action of the latter. When an atom, one of the supports, located under the frame to be welded, is provided with a bed. Meggo.m. To support it 2.

This machine, although it provides prevention of deflection of the welded frame, however, the cradle, the passage in constant contact with the rotating frame, creates significant friction, and in the case of manufacturing frames of a straight section, the frame appears to be enie and the beating of the frame causes Impact production and deterioration of welding quality.

disadvantages degrade the quality of the frames and reduce the reliability of the device.

The purpose of the invention is to improve the quality of the frames and the reliability of the device.

This goal is achieved by the fact that in the device for welding spatial reinforcement cages, containing a welding unit, a pulling carriage, a support provided with a lodgement mounted at an angle to the longitudinal axis of the device, is made in the form of a closed flexible element encompassing the rollers mounted on the supports of the support, the supports are hingedly mounted and podpruzhieny relative to the support.

In addition: JToro, with the prevention of the slide and the flexible element from the rollers, on) the surface of the rollers is made with annular grooves for accommodating the flexible element.

With this design of the device, the longitudinal axis of the frame retains its position in space unchanged. This is due to the fact that when vrangheniya rectangular cross-sectional framework, the rate from the axis of the frame to the lodgement and the condition of nguyu varies depending on which part of the rectangle rests on the bed.ment, which also changes the force that you transfer frame lodgement. A flexible element, having a constant length and not being able to stretch, transmits this force through rollers on a spring-loaded strut, which are retracted in the plane of the bed, enable the latter to deflect for the necessary amount, This is the product axis of the framework in space unchanged, i.e., the lateral runout of the framework is practically excluded.

The arrangement of the flexible connection in the annular grooves of the rollers excludes them from the rollers during postgate, the regegene of the framework.

FIG. 1 shows a system of two, 1 welding armature of 1x frames, an open view; in fig. 2 is a view A of FIG. one; in fig. 3 - section B - EJ in FIG. 1, when the horizontal arrangement of the frame; pas figs. 4 - the same, 1gr inclined arrangement of the frame; in fig. 5 is a sectional view BB in FIG. 3

The device comprises a frame 1, on which a rotating faceplate 2 is installed, a welding unit 3, a lifting trolley 4. a lifting and supporting support 5 on which the hinged pillars 6 and 7 with roller 8 and 9 are mounted. Sharggirnga racks 6 and 7 have a second connection with support 5 by means of springs 10 and P. Rollers 8 and 9 (PkhaP) P5a1Ots bending, item 1, 12, is located in the circular grooves 13.

The faceplate 2 causes rotation the longitudinal reinforcement of the framework to which the transverse reinforcement is wound and welded by the welding unit 3 in the process of moving with its carrying carriage 4. The tilt-and-turn support 5 rises to the required height to support the frame 15 with the flexible element 12. The rotating frame 15, having a rectangle in cross section, presses against the cradle with different force. The flexible element 12 transmits the force to the rollers 8 and 9 which, overcoming the force of the springs 10 and 11, are shifted or moved apart in the plane of the lodgment. The springs 10 and II are adjusted so that when the frame rotates, the distance between the rollers changes from 1 to Ij. depending on which part of the frame interacts with the lodgment. At the same time, the distance h from the base of the support to the axis of rotation of the frame remains almost unchanged.

Thus, the execution of the support of the lodgement with the rollers having the possibility of movement in the plane of the lodgement ensures the rotation of the carcass without a beat, and the location of the flexible element in the annular grooves of the rollers excludes the sliding of the flexible connection from the rollers during translational-rotational movement of the carcass.
