Technical Field

The utility model belongs to the technical field of the concrete tubular pile processing technique and specifically relates to a concrete tubular pile automatic demoulding device.

Background

In the prior art, a concrete pipe pile is centrifugally formed in a pipe pile die, and after the concrete pipe pile is cooked and dried, the formed pipe pile needs to be demoulded. At present, the upper die is disassembled and then the tubular pile is lifted out of the lower die by the travelling crane, but the stress positions of the joints of the travelling crane and the two ends of the tubular pile are concentrated, so that the tubular pile is easily damaged, and the quality of a tubular pile product is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the technical problem that not enough provides an automatic shedder of concrete pipe pile, can utilize tubular pile self gravity to carry out the drawing of patterns.

In order to achieve the purpose, the utility model relates to an automatic demoulding device for a concrete pipe pile, which comprises a crossbeam and a frame arranged at two ends of the crossbeam, wherein two ends of the crossbeam are rotationally connected with the frame through a rotating shaft, the middle part of the upper surface of the crossbeam is provided with an arc-shaped concave structure, the arc-shaped concave structure is matched with a pipe pile mould, two sides of the arc-shaped concave structure are respectively provided with a claw arm, the crossbeam at the corresponding position of the claw arm is provided with a concave cavity, the lower end of the claw arm extends into the concave cavity, the middle part of the claw arm is connected with the side wall of the concave cavity through a pin shaft, the axial direction of the pin shaft is axially consistent with the rotating shaft at the end part of the crossbeam, the top of the claw arm extends towards one side of the pipe pile mould, the crossbeam at the outer side of the claw arm extends upwards to form a supporting rod, the electromagnet is positioned on the inner side of the claw arm, a gap is reserved between the electromagnet and the claw arm, the lower end of the cross beam is provided with a downward convex arc-shaped rack, the rack is provided with a power mechanism, and an output gear of the power mechanism is connected with the arc-shaped rack in a matched manner; under the natural state, the claw arm is in vertical position, and the claw hook catches the edge of tubular pile mould, and the interval between claw arm and the electro-magnet is greater than the width that the claw hook caught the tubular pile mould.

Above-mentioned technical scheme, in the actual process, place the tubular pile mould after the tubular pile mould cooking shaping inside the arc indent structure of crossbeam, then will go up the mould and demolish, demolish the mould back, the claw hook on the claw arm of lower mould both sides hangs the lower mould of tubular pile mould under the effect of pressure spring for the tubular pile mould is fixed on the crossbeam. Then utilize power unit's output gear to rotate and drive the arc rack and rotate, thereby make whole crossbeam take the tubular pile mould to a lopsidedness, when inclining to the certain degree, whole tubular pile rolls out in the lower mould of tubular pile mould under the effect of gravity, can set up the shock pad in the position department that the tubular pile mould dropped from the tubular pile mould simultaneously, like the rubber pad etc., carry out the shock attenuation processing to the tubular pile, avoid the tubular pile to damage, the shock pad can have certain inclination simultaneously, the tubular pile can roll to one side under inclination's effect behind the shock pad, be convenient for the later stage is carried and is deposited. If the drawing of patterns is not very smooth and easy between tubular pile and the mould, can utilize power unit to carry out the reciprocating motion of minizone and realize the shake of tubular pile mould to tubular pile from inside droing, realize automatic drawing of patterns, and the stability of drawing of patterns process is high, and the damage to the tubular pile is little. In addition, when the tubular pile die needs to be taken out after demolding, the electromagnet can be started, the lower end of the claw arm is adsorbed to the inner side by the electromagnet, so that the upper end of the claw arm swings outwards, the claw hook and the tubular pile die can be threshed, the tubular pile die can be taken out by a travelling crane, simplicity and convenience are realized, and the operability is high.

As optimization, at least two claw arms are arranged on each side of the arc-shaped concave structure, and the claw arms are uniformly arranged at intervals. Set up the claw arm at tubular pile both ends preferentially, remaining claw arm is at the even interval arrangement of tubular pile within range to the connection to tubular pile mould is more firm, and stability is high.

The utility model provides a concrete tubular pile automatic demoulding device, it can realize the tubular pile from the interior automatic demoulding of tubular pile mould through reasonable structural design, and drawing of patterns process is reliable and stable, and is little to the damage of tubular pile.
