Description

The invention relates to the construction, in particular to devices for the manufacture of reinforcement cages for reinforced concrete piles.

The aim of the invention is the expansion of technological capabilities.

Fig, 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

The device comprises a frame 1, a mechanism .2 for feeding rods of a longitudinal armature with clamps 3, a mechanism 4 for winding transverse reinforcement and a mechanism 5 for fastening it with a longitudinal reinforcement, a core 6, roller supports 7 and a rack 8, Mechanism 2 for feeding the rods of longitudinal reinforcement consists from the frame 9, in the guides 10 of which the carriage 11 with the pneumatic actuator 12 is installed. On the frame of the carriage 11, spring-loaded levers 13 and additional levers 14 of the clips 3 of the mechanism 2 for feeding the rods of the longitudinal reinforcement are hinged. The levers 13 and 14 on the side of the longitudinal reinforcing bars 15 are equipped with interchangeable clamping jaws 16. The spring-loaded levers 13 are combined on one side by extension springs 17, and on the other side are equipped with stop rollers 18, Additional levers 14 are combined in pairs by cross-pieces 19 and attached to them with the possibility of rotation relative to the axis 20, installed in the longitudinal grooves of 21 additional levers 14. The crossbars 19 are hingedly mounted on the rods of the power cylinders 22 and are equipped with pushers of a wedge 23 that interact with ornymi rolls 18 spring-loaded arms 13.

The device works as follows.

In the initial position, the levers 13 and 14 of the clamps 3 are apart. The longitudinal reinforcement bars 15 are laid on the rack 8 so that their ends are between the levers 13 and 14. They turn on the air supply to the power cylinders 22, the rods of which move the traverse 19 and the pushers 23 mounted on them, which

interacting with resistant rollers 18, deploy the spring-loaded levers 13 in the working position and fix them in this position. The yoke 19, while continuing to move, turns the additional levers 14 and, through the interchangeable clamping jaws 16, presses the longitudinal reinforcement bars 15 to the spring-loaded levers 13 with the required force.

The carriage 11c is clamped by longitudinal reinforcing bars 15 moves along the guides 10 by the required pitch. Clips 3 are consumed and carriage 11 returns them to their original position. The process is repeated until the complete production of the frame.

The use of the invention in the manufacture of pile piles with increased bearing capacity, having 2 or more rods in the corner, reduces the amount of manual labor due to the mechanization of the process of laying longitudinal reinforcement into the frame feeding mechanism.
