Description

Technical Field

[0001] The utility model belongs to a punching tool for suspender bars in building construction, in particular to a punching tool for suspender bars in building installation construction controlled by a scissor lift. Background Art

[0002] For traditional suspender bar installation, a portal frame scaffold needs to be erected to determine the position of the suspender bars according to the specifications and construction plan. Workers stand on the portal frame scaffold and hold a pneumatic drill in their hands to punch holes at the positioning points. The portal frame scaffold needs to be moved every two or three holes, resulting in extremely low construction efficiency. There is also a relatively convenient construction method, which is to tie a pneumatic drill to the end of a steel pipe and have a worker hold the other end to punch holes at the positioning points. This method has great potential safety hazards and is prone to construction errors, causing difficulties in subsequent construction. Content of the Utility Model

[0003] The purpose of the utility model is to provide a punching tool for suspender bars in building installation construction controlled by a scissor lift, which has a reasonable structure, can not only punch holes quickly and accurately, improve work efficiency, but also ensure the safety of workers during operation.

[0004] The purpose of the utility model is realized as follows: A punching tool for suspender bars in building installation construction controlled by a scissor lift includes a manual scissor lift. Universal wheels are installed at the bottom of the base, and a vertical laser emitter is installed at the center of the base. The manual scissor lift is fixedly installed on the base. The central hole of the lifting seat of the manual scissor lift is concentric with the emission center of the vertical laser emitter. An adjustable-length support column is fixedly connected to the lifting seat of the manual scissor lift, and a pneumatic drill is fixedly installed on the support installed at the upper end of the adjustable-length support column.

[0005] The utility model consists of four major parts, namely the base part, the hoist part, the support column part, and the impact drill part. The base part is a square frame of 1m * 1m welded by four square steel pipes. The two square steel pipes at the bottom are vertically crossed. Universal wheels are installed at both ends of the lower square steel pipes respectively, and a laser emitter is installed at the central position for convenient point finding. The main body of the hoist part is a scissor-type hand-operated hoist. The lower support of the hoist is connected to the square steel pipe of the base part using bolts and nuts, ensuring that the middle position of the hoist and the middle position of the base part are at the same point and firmly fixed. The support column part consists of three sections of steel pipes. One is that one end of the lower steel pipe is welded to the jacking part of the hoist, with the center points corresponding, and another welding sleeve. One end of the middle steel pipe is threaded, and the other end is welded with a sleeve. Steel pipes of different lengths can be selected according to the construction operation height. The lower end of the upper steel pipe is threaded, and the upper end has a notch for connecting the impact drill. The three sections of steel pipes are connected using special sleeves. The impact drill part is mainly composed of an impact drill, which is vertical. The bottom of the impact drill is connected to the notch at the top of the support column. Finally, ensure that the midpoints of the four parts of the base, hoist, support column, and impact drill are on the same line.

[0006] Construction process:

[0007] First, transport each component to the corresponding floor of the construction site. Select steel pipes of different lengths for the support column according to the height of the floor. After assembly, move the tool to the designated point according to the positioning, ensuring that the point emitted by the laser emitter under the base is the same as the drilling point. Then, power on the impact drill, and the worker slowly uses the hand-operated hoist to lift the height of the impact drill. The lifting height is different according to the depth of the hole, and thus the drilling work of one hanger bar is completed. Next, lower the hoist, move the tool to the next point and continue the construction.

[0008] The structure of the utility model is reasonable, achieving fast and accurate drilling, improving work efficiency, and at the same time ensuring the safety of workers during operation. Description of the drawings

[0009] The following will further describe the present utility model in conjunction with the drawings. Figure 1 It is the front view structural schematic diagram of the present utility model. Figure 2 For Figure 1 The top view structural schematic diagram. Specific implementation mode
