This kind of hole opening equipment mainly relies on the cylinder movement method, which can meet the general hole opening requirements. However, the cost is relatively high, and a set of hole opening equipment needs thousands of yuan. Holes are drilled by hand-held electric hammer or electric drill on the ladder, therefore, it is urgent to develop a portable and low-cost drilling equipment

The invention discloses a lever hinge type drilling ladder and a hole-forming construction method. The lever hinge type drilling ladder comprises a stand rod, a press rod, a connecting rod and a supporting rod. One end of the press rod serves as a handle end, the other end of the press rod is hinged to the top end of the supporting rod, and the middle of the press rod is hinged to the middle of the stand rod. One end of the connecting rod is hinged to the middle of the supporting rod, and the other end of the connecting rod is hinged to the top end of the stand rod. The top end of the supporting rod is provided with a fixing structure for fixing drilling equipment. A parallel four-connecting rod mechanism is formed by the stand rod, the press rod, the connecting rod and the supporting rod, and the bottom end of the stand rod is used for making contact with a floor. By means of the lever hinge type drilling ladder and the hole-forming construction method, the aim that workers can drill holes in a ceiling simply by standing on the floor is easily achieved, the construction device is light and easy to carry, cost is low, and popularization is convenient.
Description
Technical field [0001] The invention relates to a lever articulated drilling ladder and a hole forming construction method, belonging to the field of construction drilling equipment. Background technique [0002] At present, opening holes in the ceiling of buildings are generally carried out by decoration workers standing on a herringbone ladder holding an electric hammer or electric drill. This drilling method is dusty and dangerous. Therefore, a worker standing on the floor is developed. The construction device that can open holes on the ceiling has become a research direction in recent years. [0003] Chinese patent CN201510261555.6 discloses a device that is convenient for opening holes in the ceiling, which includes an electric hammer, an electric hammer fixing seat and a movable support device. The electric hammer is fixedly installed on the electric hammer fixing seat. The movable supporting device includes a movable base, an air cylinder, and a control mechanism for contro...
