Description

Technical Field

[0001] The utility model relates to the field of construction tools, in particular to a portable mobile cylinder boosting drilling device. Background Art

[0002] During installation operations such as building decoration, wiring, and installing air-conditioning ducts, it is often necessary to drill holes in the ceiling of a building. The holes are used as anchoring points to install facilities such as electric wires, water pipes, and ventilation ducts. The accurate drilling ability and easy operation of an impact drill make the installation work more convenient. Currently, when using an impact drill to drill holes in the ceiling, a movable scaffold is usually used as an auxiliary tool, and the operator climbs onto the scaffold and holds the impact drill to drill holes. There is also a case where a movable lifting platform is used as an auxiliary tool, and the operator rises to a predetermined position on the lifting platform and holds the impact drill to drill holes. The above-mentioned drilling methods are all carried out in the air, and the dust generated by drilling will directly fall on the construction workers below. There are problems such as high physical consumption of the operators, high danger coefficient, serious dust pollution, and low drilling efficiency, and it is necessary to design a professional tool to solve this problem.

Specific implementation mode

[0022] Example 1, referring to the attached drawings of the specification Figures 1-3 and 6, a portable mobile cylinder boosting drilling device, including a square tube column 21 fixedly installed at one end of a support base plate 01. Rollers 11 are provided at the four corners of the bottom surface of the support base plate 01. A primary slide bar 22 is slidably sleeved in the square tube column 21. A secondary slide bar 23 is slidably sleeved in the primary slide bar 22. The secondary slide bar 23 and the primary slide bar 22 are also square tube bars, which can prevent relative rotation between each other. An expansion push rod is provided on the support base plate 01 on one side of the support column. The expansion end of the expansion push rod is connected to the upper end of the primary slide bar 22, which can drive the primary slide bar 22 to slide up and down in the square tube column 21. An upper hanging seat 211 is provided on the outer side surface of the upper end of the square tube column 21. The upper hanging seat 211 is a section of channel steel. A cross bar is connected between the two ear plates of the channel steel by screws. A hanging plate is provided in the middle of the cross bar. A sprocket seat 221 corresponding to the position of the upper hanging seat 211 is provided at the end of the primary slide bar 22. A lower hanging seat 234 is provided at the bottom of the secondary slide bar 23. A chain 24 is connected in the upper hanging seat 211. The chain 24 meshes with the sprocket 222 in the sprocket seat 221 upwards and then extends downwards into the secondary slide bar 23 and is connected to the lower hanging seat 234 at the lower end of the secondary slide bar 23. When the primary slide bar 22 rises, it will push up the chain 24 through the sprocket 222. The free end of the chain 24 pulls the lower end of the secondary slide bar 23 upwards through the lower hanging seat 234, realizing two-stage telescoping of the slide bar to adapt to the height of the ceiling.

[0023] An air compressor 31 is provided on the support base plate 01. The telescopic push rod is a cylinder 32. The air compressor 31 provides high-pressure gas for the cylinder 32. The cylinder 32 has a high speed and a large output power, providing a strong and rapid jacking pressure for the slide bar to ensure the drilling quality and efficiency. An L-shaped support is provided at the upper end of the secondary slide bar 23. The impact drill 232 is fixedly connected to the L-shaped support through a buckle 233.

[0024] A square tube seat 12 is vertically provided in the middle of the square tube column 21. A T-shaped grip rod 13 is sleeved in the square tube seat 12. The T-shaped grip rod 13 and the square tube seat 12 are fixedly connected by bolts. The operator can push the drilling device to move freely through the T-shaped grip rod 13, and a control button is provided on the T-shaped grip rod 13 to control the cylinder 32 through this control button.

[0025] Two diagonal braces 14 are symmetrically provided in the middle of the square tube column 21. The lower ends of the diagonal braces 14 are fixedly connected to the corners of the support base plate 01. The square tube column 21 is strengthened through the diagonal braces 14 to ensure its sufficient support strength and stability. A U-shaped sleeve 141 is provided between the upper ends of the two diagonal braces 14. The U-shaped sleeve 141 is sleeved on the square tube seat 12. The U-shaped sleeve 141 and the square tube seat 12 are fixedly connected by bolts. These components such as the square tube seat 12 and the U-shaped sleeve 141 facilitate the docking installation of the grip rod and the diagonal braces 14 and also facilitate later disassembly and replacement.

[0026] During the drilling operation, the operator holds the T-shaped grip rod 13 and pushes the device to move to the drilling position. Then, the air compressor 31 is started to drive the piston rod 321 of the cylinder 32 to extend. The piston rod 321 drives the primary slide bar 22 to slide upward in the square tube column 21 through an angle iron seat 33. During this process, the sprocket 222 at the upper end of the primary slide bar 22 presses the chain 24 upward. The free end of the chain 24 pulls the lower end of the secondary slide bar 23 to slide upward through a lower hanging seat 234. The secondary slide bar 23 slides upward in the primary slide bar 22, realizing two-stage telescoping, so that the impact drill 232 at the upper end reaches the height of the ceiling. Then, the cylinder 32 continues to push outward and continuously applies a jacking pressure to drive the impact drill 232 to perform the drilling operation, eliminating the need for the operator to work at height and effectively improving the safety and efficiency of the drilling operation.

[0027] Example 2, see the attached instructions Figures 3-5, on the basis of the first embodiment, an angle iron seat 33 is provided at the upper end of the first-level slide bar 22. A long hole 331 is provided on the horizontal plate of the angle iron seat 33. A stud 332 that is slidably inserted into the long hole 331 is provided at the upper end of the piston rod 321 of the air cylinder 32. A nut 333 is connected to the upper end of the stud 332. The stud 332 has a certain amount of movement allowance in the long hole 331 to avoid the phenomenon that the piston rod 321 and the angle iron seat 33 are jammed due to the change of the assembly accuracy during long-term use, ensure that the air cylinder 32 has sufficient power, and a groove 235 is provided on the side surface of the second-level slide bar 23 along its length direction. After passing through the sprocket 222, the chain 24 enters the groove 235 downward and is connected to the lower hanging seat 234. The groove 235 forms a chain 24 channel in the second-level slide bar 23, which can play a role in guiding and protecting the movement of the chain 24. The chain 24 pulls the second-level slide bar 23 to slide relative to the first-level slide bar 22 in this channel.
