Description

Technical Field

[0001] This utility model relates to the field of ventilation duct processing technology, specifically to a drilling device for ventilation duct processing. Background Technology

[0002] Ventilation ducts are metal or composite pipes used in ventilation and air conditioning systems of industrial and civil buildings. They are a type of municipal infrastructure designed to circulate air and reduce the concentration of harmful gases. Ventilation ducts are typically made of rolled sheet metal. To connect adjacent ventilation ducts, mounting holes are usually made in the sheet metal before the ducts are fabricated, allowing for the later connection and fixation of two ventilation ducts using bolts and nuts.

[0003] A search revealed Chinese patent application number 202222197926.7, which discloses a drilling device for processing ventilation ducts. The device includes a frame and a mounting plate. A pad is slidably mounted on the top of the frame. A drilling mechanism is mounted on the mounting plate, comprising a clamping assembly, a drilling assembly, a lifting assembly, and a driving assembly. The clamping assembly includes a movable plate mounted on the mounting plate and a lower cylinder fixed to the bottom surface of the movable plate. The drilling assembly is mounted on the bottom of the movable plate. The lifting assembly controls the lifting of the movable plate, and the driving assembly controls the movement of the lifting assembly along the sliding direction of the pad. When drilling ventilation duct materials, the operator places the material on the pad and controls the lower cylinder to operate, causing the lower end of the piston rod of the lower cylinder to press against the upper surface of the material, thus positioning the material. This facilitates the positioning of materials of different sizes and specifications, improving the quality of the drilling process.

A first electric slide rail and a second electric slide rail are respectively provided on the top of the base 1. A sliding frame 3 is fixedly connected to the output end of the first electric slide rail. A clamping block 4 is symmetrically rotatably connected to the surface of the sliding frame 3 about the three-jaw chuck 2, and the clamping block 4 is conical in shape. An anti-slip pad is fixedly connected to the surface of the clamping block 4. A movable frame 5 is fixedly connected to the output end of the second electric slide rail. A bearing plate 6 is fixedly connected to the side of the movable frame 5 near the three-jaw chuck 2. An electric telescopic rod 7 is fixedly connected to the top of the bearing plate 6. The output end of 7 is fixedly connected to the top plate 8. The center of the bottom of the top plate 8 is fixedly connected to the drilling machine 9. The output end of the drilling machine 9 is located above the center of the three-jaw chuck 2. The moving frame 5 has symmetrically opened lifting grooves on the side close to the three-jaw chuck 2. The lifting grooves are located below the bearing plate 6. The inside of the lifting groove is fixedly connected to the sliding column 10. The surface of the sliding column 10 is slidably connected to the lifting block 11. The lifting block 11 is slidably connected to the lifting groove. The outside of the lifting block 11 is fixedly connected to the protective frame 12. The bottom of the protective frame 12 is fixedly connected to the shock-absorbing pad. The inside of the protective frame 12 is slidably connected to the top plate 8. The inside of the protective frame 12 is symmetrically opened to the limit grooves 13. The two sides of the top plate 8 are symmetrically fixedly connected to the limit strips 14. The limit strips 14 are slidably connected to the limit grooves 13.

[0024] refer to Figure 1 and Figure 5 The rear side of the mobile frame 5 is provided with a storage slot. A vacuum cleaner 15 is fixedly connected to the wall of the storage slot. The output end of the vacuum cleaner 15 is connected to a hose 16. The other end of the hose 16 extends to the protective frame 12 and is connected to a suction port 17.

[0025] As a technical optimization of this utility model, by setting up a storage tank, a vacuum cleaner 15, a hose 16 and a suction port 17, the vacuum cleaner 15 can generate negative pressure in the suction port 17 and the hose 16, thereby allowing debris to be sucked into the storage tank for collection and subsequent processing.

[0026] refer to Figure 3 and Figure 5 The storage slot has symmetrical pressure relief ports 18 on both sides. The inner wall of the pressure relief port 18 is fixedly connected with a dustproof net 19. The bottom of the storage slot is slidably connected with a collection drawer 20. The outer side of the storage slot is hinged with a maintenance door, which is located above the collection drawer 20.

[0027] As a technical optimization of this utility model, the setting of pressure relief port 18, dustproof net 19 and collection drawer 20 can keep the air pressure in the storage tank balanced, and the dustproof net 19 can prevent debris from overflowing out through the pressure relief port 18. The setting of maintenance door makes it convenient for staff to replace and clean the dustproof net 19 and maintain the dust collector 15.

[0028] refer to Figure 2 and Figure 4 The front of the mobile frame 5 is fixedly connected to a slide plate 21, and the slide plate 21 is slidably connected to the base 1. The top of the slide plate 21 is symmetrically provided with guide grooves, and the inside of the guide grooves is slidably connected to guide strips 22. The top of the guide strips 22 is fixedly connected to a dust collection hopper 23, and the dust collection hopper 23 is located directly below the protective frame 12.

[0029] As a technical optimization of this utility model, by setting up the slide plate 21, guide groove, guide strip 22 and dust collection hopper 23, the debris that is not collected in the protective frame 12 can fall into the dust collection hopper 23 under the action of gravity for collection, thereby facilitating subsequent processing.

[0030] refer to Figure 3 A buffer spring is fitted on the surface of the sliding column 10, and the buffer spring is located above the lifting block 11.

[0031] As a technical optimization of this utility model, the setting of the buffer spring can buffer the lifting and lowering of the protective frame 12, and avoid the protective frame 12 from having a hard collision with the ventilation duct.

[0032] refer to Figure 2 The other end of the clamping block 4 passes through the sliding frame 3 and is fixedly connected to the crank plate, and a hand crank is fixedly connected to the surface of the crank plate.

[0033] As a technical optimization of this utility model, the design of the crank disc and the crank hand makes it easier for the operator to rotate the clamp 4, thereby improving the practicality of the device.

[0034] The working principle and usage process of this utility model are as follows: When using this drilling equipment to process ventilation ducts, one end of the ventilation duct is first clamped by the three-jaw chuck 2. Then, the first electric slide rail is activated to move the sliding frame 3 and the clamping block 4 horizontally, so that the conical surface of the clamping block 4 abuts against the other end of the ventilation duct, thereby clamping the ventilation duct. Then, the second electric slide rail is activated to move the moving frame 5 and the drilling machine 9 to the designated position. Then, the electric telescopic rod 7 and the drilling machine 9 can be activated. At this time, the electric telescopic rod 7 moves the top plate 8 down, and then the upper part of the limiting strip 14 abuts against the top of the limiting groove 13 to move the protective frame 12 down. When the shock-absorbing pad at the bottom of the protective frame 12 contacts the ventilation duct, the position of the protective frame 12 does not move, and the limiting strip 14 slides in the limiting groove 13, thereby enabling the ventilation duct to be clamped. The drilling machine 9 drills holes in the surface of the ventilation duct. The protective frame 12 and the top plate 8 prevent debris from flying everywhere. At this time, the vacuum cleaner 15 can be turned on to create negative pressure in the suction port 17 and the hose 16, which can suck the debris into the collection tank and fall into the collection drawer 20 for collection, so that it can be processed later. At this time, the pressure relief port 18 keeps the air pressure in the collection tank balanced, and the dust net 19 can prevent the debris from overflowing out through the pressure relief port 18. The dust collection hopper 23 can collect the debris that is not collected in the protective frame 12 by gravity. In this way, the drilling equipment can avoid the phenomenon of a large amount of debris flying everywhere when drilling ventilation ducts, thereby reducing debris pollution and facilitating daily use by workers.
