Description

Technical Field

[0002] Cement poles are mainly composed of steel bars and concrete, so they are also called reinforced concrete cement poles. They are mainly used as line support pillars in the power, communications, railways, petroleum and other industries.

[0003] According to a disclosed clamping device for demoulding cement poles (publication number: CN216465319U), in the above application, the upper half of the mold that is in a buckled state and placed stably is first lifted and placed, and then the lower half of the mold is lifted so that the exposed part of the cement pole adhered to the mold is placed stably in the seat bracket. At this time, the hydraulic cylinder is started to drive the clamping strip installed on the slat to rotate, and the slider installed on the clamping strip slides in the through groove, so that the clamping arm moves inward at the same time, and the clamping pad installed on the clamping arm clamps the surface of the cement pole. Finally, the hoisting machine lifts the lower half of the mold and successfully separates it from the pole.

[0004] The device clamps the pole by synchronously rotating two sets of clamp arms and cooperating with clamp pads. However, the pole is usually a tapered pole, and the outer wall diameter at the top is smaller than the outer wall diameter at the bottom. Due to the shape limitation of the pole, the synchronous rotation of the two sets of clamp arms cannot make the two sets of clamp pads fully fit the outer wall of the pole. The clamping effect is general and it is not convenient to separate from the bottom mold. Utility Model Content
