Description

Technical Field

[0001] The utility model relates to the technical field of ventilation duct edge trimming, in particular to a portable ventilation duct edge trimming device. Background Art

[0002] A pneumatic hammer (also known as an air hammer or pneumatic percussion hammer) is an indispensable professional tool in the installation of ventilation ducts. Pneumatic hammers are mainly used for sealing, tapping, and closing ventilation ducts. They use compressed air to drive the hammer head to vibrate at high frequencies, quickly smoothing the edges of sheet metal ducts and significantly improving construction efficiency. Compared with traditional manual hammering, pneumatic hammers are more labor-saving to operate and can ensure the smoothness of the edges. The finishing of ventilation ducts is a key step in the installation of ventilation systems, which directly affects the sealing, stability, and service life of the system. Finishing can enhance the sealing, stability, and durability of ducts. Inadequate finishing can lead to air leakage, increased energy consumption, and reduced system efficiency. Good finishing can prevent deformation or falling of the ducts, ensuring the safe operation of the system. Improper finishing may cause corrosion or damage to the duct interfaces, shortening their service life.

[0003] However, most common ventilation duct edge trimming devices are pneumatic hammers. When using a pneumatic hammer to trim the edge of the duct, the worker usually holds the pneumatic hammer with both hands and then strikes the duct to trim the edge. During use, the worker's arms will become sore due to vibration, which is not conducive to long-term use. Therefore, there is room for further improvement.

[0004] Therefore, we propose a portable ventilation duct edge trimming device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-5 As shown, the utility model provides a technical solution: a portable ventilation duct trimming device, including: a moving vehicle 1, a vertical plate 2, a first connecting plate 3, a first threaded rod 4, a first motor 5, a limiting rod 6, a connecting block 7, a connecting bolt 8, a second connecting plate 9, a fixed block 10, a pneumatic hammer 11, a connecting rod 12, a fastening nut 13, a connecting sleeve 14, a moving block 15, a sliding groove 16, a second threaded rod 17 and a second motor 18.

[0034] Common ventilation duct trimming devices are mostly pneumatic hammers 11. When using the pneumatic hammer 11 to trim the edge of the duct, the worker usually holds the pneumatic hammer 11 with both hands and then strikes the ventilation duct to trim the edge. During use, the worker's arms will become sore due to vibration, which is not conducive to long-term use. Therefore, there is room for further improvement.

[0035] like Figure 1 and Figure 3 As shown, the lower side of the mobile cart 1 is provided with moving wheels, and the upper side of the mobile cart 1 is provided with handrails. The mobile cart 1 can be moved by holding the handrail. In actual operation, it is only necessary to move the mobile cart 1 so that the pneumatic hammer 11 is relatively parallel to the edge of the ventilation duct; and a vertical plate 2 is provided on the upper side of the mobile cart 1, the vertical plate 2 is slidingly connected to the first connecting plate 3, the first connecting plate 3 is threadedly connected to the first threaded rod 4, the first threaded rod 4 is rotatably connected to the vertical plate 2, the first threaded rod 4 is fixedly connected to the output shaft of the first motor 5, and the first motor 5 is fixedly connected to the vertical plate 2. Starting the first motor 5 can make the first connecting plate 3 move up and down, which is convenient to use.

[0036] like Figure 2 and Figure 5As shown, the connecting block 7 fits tightly with the first connecting plate 3, the connecting block 7 is rotatably connected with the connecting bolt 8, the connecting bolt 8 is symmetrical front and back about the vertical center axis of the first connecting plate 3, the connecting block 7 is fixedly connected with the second connecting plate 9, and a fixed block 10 is provided on the upper side of the second connecting plate 9. The second connecting plate 9 is fixedly connected with the pneumatic hammer 11, so the pneumatic hammer 11 will rotate with the first connecting plate 3 through the second connecting plate 9, which is convenient for use; the fixed block 10 is rotatably connected with the connecting rod 12, the connecting rod 12 is threadedly connected with the fastening nut 13, the connecting rod 12 is slidably connected with the connecting sleeve 14, the connecting sleeve 14 is rotatably connected with the moving block 15, the moving block 15 is slidably connected with the sliding groove 16, and the sliding groove 16 is provided inside the first connecting plate 3, which is convenient for fixing the angle of the pneumatic hammer 11 after the pneumatic hammer 11 is rotated.

[0037] Directions:

[0038] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, in the initial state, the pneumatic hammer 11 is perpendicular to the ground, and the first motor 5 is started. The first motor 5 will rotate the first threaded rod 4, and the rotating first threaded rod 4 will make the first connecting plate 3 move up and down, and the first connecting plate 3 is slidably connected to the limit rod 6, so the limit rod 6 plays a limiting role on the first connecting plate 3, so that the first connecting plate 3 moves up and down in the vertical plate 2, and then the pneumatic hammer 11 is moved up and down through the first connecting plate 3 and the second connecting plate 9, so that the lower side of the pneumatic hammer 11 is tightly fitted with the upper side of the ventilation duct, which is convenient for trimming the ventilation duct, and then the mobile car 1 is moved to allow the pneumatic hammer 11 to trim different parts of the ventilation duct.

[0039] like Figure 2 、 Figure 4 and Figure 5 As shown, the first connecting plate 3 fits tightly with the connecting block 7, and the connecting block 7 is rotatably connected to the first connecting plate 3 by the connecting bolt 8. Therefore, when the connecting bolt 8 is disconnected from the first connecting plate 3, the connecting block 7 can be removed from the first connecting plate 3; in addition, the connecting rod 12 is slidably connected with the fastening nut 13. When the connecting rod 12 needs to be removed, the fastening nut 13 at the outer end of the connecting rod 12 is first removed, and then the second motor 18 is started. The output shaft of the second motor 18 is fixedly connected to the second threaded rod 17, so that the second threaded rod 17 will rotate. Since the second threaded rod 17 is threadedly connected to the moving block 15, the moving block 15 will move in the sliding groove 16, thereby disconnecting the connecting sleeve 14 from the connecting rod 12, thereby achieving the purpose of disassembly and conveniently carrying separately.

[0040] It should be noted that after the connecting rod 12 is connected to the connecting sleeve 14, fastening nuts 13 are provided at both ends of the connecting sleeve 14 on the outside of the connecting rod 12. The fastening nuts 13 provided at two places can enhance the stability of the connection between the connecting sleeve 14 and the connecting rod 12, facilitate the use of edge finishing, and avoid the vibration generated during edge finishing from affecting the work. In addition, in order to prevent the fastening nut 13 from being lost after disassembly, the fastening nut 13 can be threadedly connected to the connecting rod 12, and can be removed and reinstalled when used next time.

[0041] like Figure 3 and Figure 5 As shown, when it is necessary to trim the side of the ventilation duct, start the second motor 18, and the second motor 18 will rotate the second threaded rod 17, so that the movable block 15 can slide in the sliding groove 16. Since the connecting sleeve 14 is connected to the connecting rod 12 by the fastening nut 13, and the first connecting plate 3 and the second connecting plate 9 are rotatably connected through the connecting block 7, the moving movable block 15 will cause the fixed block 10 to rotate with the second connecting plate 9 through the connecting rod 12, thereby tilting the pneumatic hammer 11, so that the pneumatic hammer 11 can trim the side of the ventilation duct. When working, you only need to control the moving vehicle 1 to complete the work.

[0042] It should be noted that since the material of the ventilation duct is relatively soft, the device can be used to complete the trimming. If you are worried that vibration will affect the operation of the device, you can add a counterweight block on the upper side of the mobile vehicle 1 to increase the weight of the device to offset the impact of vibration on the device, so that it can work normally.
