When the equipment is moving, the electrical equipment can be controlled, the electric hammer 4 is immediately powered off after completing the drilling, and the hole is not expanded; the electric hammer 4 is directly stopped after drilling, which can also save energy.

[0031] It also includes an air pump 13, the air pump 13 is connected with the air inlet of the pneumatic stroke switch 10 through the air inlet pipe 14, the two air outlets of the pneumatic stroke switch 10 are connected with the air inlet of the air cylinder 5 through the air inlet pipe, and the middle part of the U-shaped handle 9 is provided with an air pressure gauge 15 on the pipeline of the air inlet pipe 14.

[0032] As shown in the figure, Figure 1 In the selection of technical parameters of the air pump 13, according to the actual situation on site, the exhaust pressure ≤1.0Mpa, the exhaust volume ≤5m³ / min, the equipment power ≤202kW, the rotating speed is controlled between 1000 - 3000r / min, single-stage compression is adopted, the energy efficiency ratio ≤4, and the noise is controlled between 60 - 80dB, which can meet the use requirements on site; the reading of the air pressure gauge 15 is used to control the size of the air pressure, according to the actual demand on site, the air pressure can be kept between 0.5MPa—1.0MPa, so that the piston rod of the air cylinder 5 can produce a thrust of 100kg—300kg, meeting the power demand on site, and realizing the efficient work on site.

[0033] The top of the L-shaped bracket 3 is equipped with a travel limit switch 16 and a travel switch adjuster 17. The travel limit switch 16 is arranged parallel to the drill bit of the electric hammer 4.

[0034] like Figure 2 As shown, the travel limit switch 16 and the travel switch adjuster 17 can adjust the drilling depth of the electric hammer 4. The height of the travel limit switch 16 can be adjusted according to the actual site conditions so that the drilling depth of the electric hammer 4 meets the design and specification requirements. When the travel limit switch 16 touches the ceiling, the electric hammer 4 stops working. The travel limit switch 16 and the travel switch adjuster 17 are switches that use the collision of mechanical moving parts to trigger an electrical signal. This is an existing technical structure, and the specific structural principle will not be described in detail.

[0035] Operating principle: After the device arrives at the construction site, assemble all its components to make it operational. Then, adjust the power supply and air pressure, and test the device to make it ready for on-site construction. Control the drilling depth of the electric hammer 4 by adjusting the travel limit switch 16 and travel switch regulator 17. While moving the device by pushing the U-shaped handle 9, press the pneumatic switch 11 to control the cylinder 5 to drive the electric hammer 4 upward. Specifically, the cylinder 5 drives the secondary lifting rod 202 upward, and the upward movement of the secondary lifting rod 202 drives the sprocket 204 upward. Under the action of 5, while the secondary lifting rod 202 rises, the tertiary lifting rod 203 will be lifted simultaneously, driving the electric hammer 4 to rise. During the rising process, the electric hammer 4 is not activated and will not shake, making the hole positioning more accurate and helping to ensure successful drilling. After positioning, the electric hammer switch 12 is turned on to drill a hole in the ceiling. After the electric hammer 4 reaches the required drilling depth, it touches the travel limit switch 16, causing the electric hammer 4 to stop working. After drilling is completed, the lifting assembly 2 is retracted by the pneumatic switch 11, causing the electric hammer 4 to move downward and disengage from the working hole, completing the drilling work.

[0036] Example 2: The electric hammer drilling device for ceilings provided by this utility model has been applied in the comprehensive building project of the Women and Children's Ward of Weishi People's Hospital, undertaken by Zhengzhou No. 1 Construction Group, and has achieved good social and economic benefits. The building area of ​​the project is 41,200 square meters. During operation, the equipment has low power consumption and requires fewer operators, thus improving efficiency and reducing costs. The application of the equipment has made the work surface clean and tidy. The flexible and convenient device is more stable during operation and generates relatively less noise.

[0037] Economic benefit calculation:

[0038] According to the layout of the suspended ceiling hole with an area of 1 / m2, about 41200 holes are needed; originally, it takes 5 minutes to complete a ceiling punching operation, and 2 people work together to complete it; after using the device, it can be shortened to 2 minutes, and 1 worker can operate independently; the reward for each punching operation is 10 yuan; according to 8 hours a day, the labor cost is 300 yuan per working day, and after 5 groups of workers complete the entire work, economic cost analysis is carried out:

[0039] The original economic benefit: 41200x10-(41200 / ((60 / 5x8x5) x10x300)=154500 yuan;

[0040] Now the economic benefit: 41200x10-(41200 / ((60 / 2x8x5) x5x300)=360500 yuan;

[0041] The difference between the economic benefits of using the new device is: 360500-154510=205990 yuan

[0042] The device generates an economic benefit of 205990 yuan.

[0043] The device avoids the falling risk of workers climbing, reduces safety accidents caused by high-altitude work, and protects the life safety of construction workers. Workers do not need to hold heavy electric hammers for a long time to work at high altitudes, reducing labor intensity and making work easier; the electric hammer 4 can be easily lifted to the ceiling position without manual climbing or using complex auxiliary tools, saving time and effort, thereby greatly improving the efficiency of the punching operation; through the pneumatic hinge method, the lifting process is stable and easy to control, and the electric hammer 4 can be accurately positioned at the position where punching is needed, improving the accuracy and quality of construction; it can adapt to different height and angle ceiling punching requirements, and has strong versatility and practicality. Stable lifting and positioning help to ensure the perpendicularity and consistency of punching, thereby improving the construction quality of the entire project. By integrating the electric hammer switch 12 and the pneumatic switch 11, the operation of the entire device is more convenient, preventing the electric hammer 4 from working with electricity, improving the electrical safety of on-site operation; improving work efficiency also reduces construction cost to a certain extent.
