Construction equipment for chimneys

The utility model relates to construction equipment for a chimney. The platform of the construction equipment for a chimney is fixedly connected at a tower crane on the center. A hydraulic cylinder is arranged on the platform, and the climbing and folding expanding action of the hydraulic cylinder can be controlled. When the platform climbs along a tower body, a door frame is driven, and the door frame and a template are connected by a bolt and a nut. The template follows the platform to upwards slide along a cylinder wall. The weight of the platform of the construction equipment for a chimney is supported by the tower crane, which ensures that the platform can not float, incline, and twist, and thus, the quality of a chimney is markedly enhanced.
