Equipment capable of punching ceiling and mounting expansion bolt conveniently

Abstract

Equipment capable of punching a ceiling and mounting an expansion bolt conveniently comprises a pedestal; a lifting device is fixedly arranged on the pedestal; the top of the lifting device is rotatably connected with a rotating platform; a drilling device and an expansion bolt mounting device are fixedly arranged on the two sides of the upper part of the rotating platform correspondingly; a cliptype feeding device is inserted into the expansion bolt mounting device; the pedestal is placed on the ground; the lifting device is used for driving the rotating platform to move up and down; the rotating platform is driven by a first driving device to rotate; the drilling device comprises a drill bit; the expansion bolt mounting device comprises a guide pipe; the upper end of the guide pipe is lower than the upper end of the drill bit; an inner hole of the guide pipe only allows a combined piece formed by combining a countersunk bolt and an expansion pipe to pass through; the guide pipe andthe drill bit are arranged on the two sides of the rotating platform symmetrically; an ejection device is fixedly arranged below the guide pipe; the clip type feeding device is internally provided with a plurality of combined pieces; the clip type feeding device is used for conveying the plurality of combined pieces to be between the guide pipe and the ejection pipe sequentially; and the equipmentsimplifies operation, has high efficiency and is safe.

Description

technical field [0001] The invention belongs to the technical field of interior decoration, and in particular relates to a device for punching holes in the ceiling and installing expansion bolts. Background technique [0002] When decorating the indoor ceiling, it is first necessary to use a percussion drill to dig a blind hole on the ceiling, and then drive the expansion bolt into the pre-excavated blind hole; the expansion bolt mainly includes countersunk bolts, expansion tubes, flat washers, spring pads and hexagonal nuts, the upper end of the countersunk head bolt is inverted tapered, and the outer peripheral wall of the lower end of the countersunk head bolt is fixed with an external thread for screwing with the hexagonal nut, and the expansion tube, flat washer and spring washer are set sequentially from top to bottom On the outer peripheral wall of the countersunk bolt, the upper end of the expansion tube is provided with a number of vertical cutouts, and the hexagona...

AI Technical Summary

Problems solved by technology

[0003] Since the ceiling is relatively high from the ground, generally 3 to 5 meters, it is necessary to climb a height, and when the percussion drill excavates blind holes, the impact force is relatively large, and the construction workers are easy to fall from a high place, causing safety accidents; and, due to the construction The personnel position is directly below the pre-opened blind hole. The construction personnel need to align with the pre-drilled hole position during construction. In this way, when the percussion drill opens the blind hole on the ceiling, the concrete slag and dust will directly fall on the construction personnel, and the concrete slag and The dust will scatter to the hair, clothes and skin surface of the construction workers, enter the respiratory tract of the construction workers, and easily confuse the eyes of the construction workers, which is not conducive to the personal health of the construction workers

[0004] When the existing equipment for drilling holes on the ceiling and installing expansion bolts is used, the equipment is generally raised to a predetermined height through the lifting device on the equipment; then, the mobile equipment is used to align the drill bit of the drilling device The position of the hole; then, dig a blind hole on the ceiling; then, lower the height of the equipment through the lifting device; then, remove the drill bit on the drilling device (the purpose of removing the drill bit is: to avoid when installing the assembly Interference between the assembly and the drill bit, that is, when the drill bit and the assembly rises with the lifting device, the drill bit will affect the smooth penetration of the assembly into the ceiling after the drill bit touches the ceiling), and at the same time put the assembly on the expansion bolt installation device; then, Use the lifting device to raise the equipment to the preset height again; then, move the equipment to align the assembly with the blind hole pre-opened by the drilling device; then, use the lifting device to drive the assembly into the blind hole, and finally , the lifting device descends to separate the equipment from the assembly; only one assembly can be loaded into the expansion bolt installation device of the existing equipment for drilling holes in the ceiling and installing expansion bolts, and each time the assembly is driven into It is necessary to move the equipment to find and align the position of the blind hole, so the existing equipment for drilling holes in the ceiling and installing expansion bolts needs to be frequently lifted, moved and aligned during construction, which is complex and inefficient.
