Technical Field

[0001] The utility model relates to the technical field of building installation engineering, in particular to a device for installing air ducts. Background Art

[0002] Installation of air duct is an important part of building installation engineering. The installation position of air duct is generally at a high height from the ground. The whole air duct is composed of multiple sections. For the installation of the currently more common suspended air duct, the installation process is to first manually lift a section of air duct and place it on the scaffolding, close to its installation height and fix it, and then lift another section of air duct to the scaffolding, dock the two sections of air duct on the scaffolding and complete the fixed installation of the air duct at both ends, and finally move the scaffolding to the installation position of the next section of air duct, repeat the above operation, and install the next section of air duct. This installation method requires manual lifting of the air duct to the scaffolding, which is not only inconvenient for vertical transportation of the air duct, but also difficult to level the two sections of air duct during docking installation, making the installation of the air duct inefficient. At the same time, construction personnel need to perform multiple steps such as air duct lifting, air duct docking and fixed installation, and moving scaffolding, which makes construction personnel prone to fatigue and increases the risk of high-altitude operations. Utility Model Content

[0003] The purpose of the utility model is to overcome the problem in the prior art that during the installation of the air duct, the air duct needs to be manually lifted to the scaffolding, which is not only inconvenient for vertical transportation of the air duct, but also difficult to level the two sections of the air duct during docking installation, resulting in low efficiency in the installation of the air duct, and to provide a device for installing the air duct.

[0004] The utility model provides a device for installing an air duct, comprising a lifting device, wherein the lifting device comprises a plurality of lifting units, the plurality of lifting units can be connected in a detachable manner, the lifting device is connected to a driving device, and the plurality of lifting units can be connected in series along the length direction of the lifting units.

[0005] By setting a lifting device including a plurality of lifting units, the plurality of lifting units can be connected in a detachable manner, the top of the lifting unit is used to place the air duct, and when the air duct is placed on the lifting unit, the length direction of the air duct is consistent with the length direction of the lifting unit, and the lifting units are connected in series along the length direction thereof, and the number of lifting units matching the length of the air duct can be selected according to the length of the air duct, thereby improving the adaptability and flexibility of the use of the lifting device; by setting a driving device, the driving device can be used to drive the lifting device to perform telescopic movement in the vertical direction, and by setting the lifting device to perform telescopic movement in the vertical direction, the lifting device can be used to lift the air duct, thereby reducing the workload of manually lifting the air duct and installing it, reducing the work intensity and the risk of high-altitude operations, and improving the installation efficiency; the plurality of lifting units are connected with the driving device, and the plurality of lifting units can be synchronously extended and retracted in the vertical direction by the drive of the driving device, and when the lifting device is extended and retracted, the top surface of the lifting device remains horizontal and in the same plane, thereby improving the stability of the installation, and also facilitating the leveling of the air duct during the overall installation.

[0006] When in use, select the number of lifting units that match the length of the air duct, connect the lifting units end to end in sequence to form a lifting device, so that the length of the lifting device can match the length of the air duct, so that the lifting device can be used to lift and install the air duct. At this time, set the height of the lifting device to the lowest, place the assembled air duct on the top of the lifting device, and then use the driving device to drive the lifting device to extend in the vertical direction, and each lifting unit in the lifting device synchronously extends in the vertical direction until the lifting height of the air duct reaches the height required for the air duct installation. At this time, install the air duct. After the air duct installation is completed, use the driving device to drive the lifting device to shrink in the vertical direction, and each lifting unit in the lifting device shrinks in the vertical direction synchronously until the height of the lifting device reaches the lowest, and then move the lifting device to the next position where the air duct is to be installed, and repeat the above steps.

[0007] Furthermore, the driving device may be a hydraulic station, or may be configured as a hydraulic pump or a motor.

[0008] Through this arrangement, a lifting device can be used to vertically transport air ducts of different lengths. The synchronous extension and retraction of each lifting unit also facilitates leveling when the air ducts are connected, thereby improving the adaptability and flexibility of the construction, reducing the workload of manually lifting and installing the air ducts, reducing work intensity and the risk of high-altitude operations, and improving installation efficiency and stability.

[0009] The lifting unit includes a base frame, a telescopic device and a top frame. The base frame is connected to the top frame through the telescopic device. The driving device can be connected to the telescopic device and drive the telescopic device to telescope in a vertical direction. The top frame can move in the vertical direction as the telescopic device telescopes.

[0010] The base frame is used for the lifting unit to contact the ground. The stability of the lifting unit can be improved by setting up the base frame. The telescopic device is used to make the lifting unit telescope in the vertical direction. By connecting the telescopic device to the base frame, the stability of the lifting unit can be improved when it is telescoped in the vertical direction. The top frame is used to place the air duct. The top frame and the base frame are connected by using the telescopic device. When the air duct is placed on the top frame, the lifting unit can drive the top frame to move in the vertical direction through the telescopic device, thereby moving the air duct up and down, reducing the workload of manually lifting the air duct and installing it, and reducing the work intensity and the risk of high-altitude operations.

[0011] Furthermore, the bottom frame and the top frame can be respectively configured to be rectangular or circular.

[0012] Furthermore, the telescopic device can be configured as a telescopic hydraulic rod or a telescopic sleeve rod, and the telescopic device is fixedly connected to the bottom frame and the top frame respectively.

[0013] Furthermore, the telescopic device can also be configured as a lifting frame composed of a plurality of lifting rods arranged crosswise in pairs, the lifting rods arranged crosswise in pairs are connected by a rotating shaft, the two ends of the lifting rod are respectively movably connected to one end of the other two lifting rods by the rotating shaft, and the two ends of the lifting frame are respectively movably connected to the top frame and the bottom frame by the rotating shaft.

[0014] The base frame is provided with universal wheels, and the base frame contacts the ground through the universal wheels.

[0015] By setting universal wheels, the base frame can contact the ground through the universal wheels, reducing the friction between the lifting unit and the ground and increasing the service life of the lifting unit. At the same time, the universal wheels can drive the lifting device to move in any direction along the ground, thereby increasing the flexibility of the lifting device.

[0016] Furthermore, the universal wheel can be configured as a rubber universal wheel or a metal universal wheel.

[0017] The number of the universal wheels is at least 2, and the universal wheels are arranged on two sides of the base frame opposite to each other.

[0018] By arranging a plurality of universal wheels and arranging the universal wheels relatively on both sides of the base frame, the balance of the lifting unit can be improved. At the same time, when some universal wheels are damaged, the remaining universal wheels can maintain normal operation, thereby improving the reliability of the lifting unit.

[0019] Furthermore, the number of the universal wheels may be 4, 5, etc.

[0020] The universal wheel is detachably connected to the base frame via a wheelbase adjustment mechanism. The base frame is rectangular. The wheelbase adjustment mechanism is used to adjust the distance of the universal wheel along the width direction of the base frame.

[0021] By connecting the universal wheels to the base frame via a wheelbase adjustment mechanism, the spacing between the relatively arranged universal wheels can be adjusted to meet the needs of different working scenarios, thereby improving the flexibility of the lifting unit. At the same time, by providing a wheelbase adjustment mechanism, the wheelbase can be quickly adjusted according to actual needs without replacing or redesigning the universal wheels, thereby making the operation more convenient. By providing an adjustment mechanism for adjusting the distance of the universal wheels along the width direction of the base frame, when the wheelbase is lengthened, the lifting unit has better stability during operation.

[0025] The ratio of the horizontal distance between the universal wheels relatively arranged along the width direction of the chassis to the width of the chassis is 1-2, and can be set to 2 or 1.5 according to actual needs.

[0026] By setting the adjustable range of the distance between the universal wheels, it is helpful to distribute the load more evenly and reduce the possibility of local excessive wear or damage of the universal wheels due to uneven load.

[0027] A plurality of the lifting units are connected via the top frame.

[0028] By arranging the lifting units to be connected through the top frame, the probability that the top frames of the lifting units can be kept at the same horizontal plane when the lifting units are extended or retracted is increased, thereby improving the stability during construction.

[0030] Furthermore, the number of the limiting parts may also be set to 3 or 4, etc.

[0031] When the air duct is placed on the top frame, the axial direction of the air duct is in the same direction as the length of the top frame. By arranging limit parts on both sides of the top frame, the possibility of preventing the air duct from rolling on the top frame is increased, thereby improving safety during construction.

[0032] The limiting part is detachably connected to the top frame via a limiting rod, the top frame is rectangular, and the limiting rod is used to adjust the distance of the limiting part along the width direction of the top frame.

[0033] The limiting parts are connected to the top frame through the limiting rods, and the spacing between the relatively arranged limiting parts can be adjusted to meet the needs of air ducts of different specifications, thereby improving the flexibility of the lifting unit.

[0055] Example 1

[0056] As attached Figure 1-8 As shown, a device for installing an air duct includes a lifting device, wherein the lifting device includes two lifting units 1, and the two lifting units 1 can be connected in a detachable manner. The lifting device is connected to a driving device 2, and the two lifting units 1 can be connected in series along the length direction of the lifting units 1.

[0057] The lifting device includes two lifting units 1, and the two lifting units 1 can be connected in a detachable manner. The tops of the two lifting units 1 are used to place the air duct 3. When the air duct 3 is placed on the two lifting units 1, the length direction of the air duct 3 is consistent with the length direction of the two lifting units 1. The two lifting units 1 are connected in series along their length direction to match the length of the air duct 3. The two lifting units are connected in series in a detachable manner, which improves the adaptability and flexibility of the lifting device. By setting the driving device 2, the driving device 2 can be used to drive the lifting device to perform telescopic movement in the vertical direction. By setting the lifting device to perform telescopic movement in the vertical direction, the lifting device can be used to lift the air duct 3, which reduces the workload of manually lifting the air duct 3 and installing it, reduces the work intensity and the risk of high-altitude operations, and improves the installation efficiency. The two lifting units 1 can be driven by the driving device 2 to synchronously extend and retract in the vertical direction, so that the top surface of the lifting device can be kept horizontal and in the same plane when the lifting device is extended and retracted, thereby improving the stability of the installation and facilitating the leveling of the air duct 3 during the overall installation.

[0058] When in use, two lifting units 1 are connected end to end to form a lifting device, so that the length of the lifting device can match the length of the air duct 3, so that the lifting device can be used to lift and install the air duct 3. At this time, the lifting device is in the initial stage, that is, the height of the lifting device is set to the lowest. After the air duct 3 is assembled, it is placed on the top of the lifting device, as shown in the attached figure. Figure 6 As shown, the driving device 2 is then used to drive the lifting device to extend in the vertical direction, and each lifting unit 1 in the lifting device extends in the vertical direction synchronously until the height of the air duct 3 lifted by the lifting device reaches the height required for the installation of the air duct 3. At this time, the air duct 3 is installed, that is, the lifting device is in the installation stage, as shown in the attached figure. Figure 7 After the air duct 3 is installed, the driving device 2 is used to drive the lifting device to shrink in the vertical direction, and each lifting unit 1 in the lifting device shrinks in the vertical direction synchronously until the height of the lifting device reaches the lowest, and the lifting device is moved to the next position where the air duct 3 is to be installed, as shown in the attached figure. Figure 8 Repeat the above steps. Figure 8 Only a portion of the installed air duct 3 and one unit of the lifting device are shown.

[0059] Furthermore, the driving device 2 may be a hydraulic station, or the driving device 2 may be configured as a hydraulic pump or a motor.

[0060] Through this arrangement, the lifting device can be used to vertically transport air ducts 3 of different lengths. The synchronous extension and retraction of the two lifting units 1 also facilitates the leveling of the air ducts 3 when they are docked, thereby improving the adaptability and flexibility of the construction, reducing the workload of manually lifting and installing the air ducts 3, reducing work intensity and the risk of high-altitude operations, and improving installation efficiency and stability.

[0061] As attached Figure 1 As shown, the lifting unit 1 includes a base frame 11, a telescopic device 12 and a top frame 13. The base frame 11 is connected to the top frame 13 through the telescopic device 12. The driving device 2 can be connected to the telescopic device 12 and drive the telescopic device 12 to telescope in the vertical direction. The top frame 13 can move in the vertical direction as the telescopic device 12 is telescoped.

[0062] Furthermore, the bottom frame 11 and the top frame 13 are both configured to be rectangular.

The driving device drives the lifting rods arranged crosswise in pairs to rotate around the rotating shaft at the intersection thereof through a hydraulic rod, so as to realize the telescopic device 2 to extend and retract in the vertical direction.

[0064] The stability of the lifting unit 1 can be improved by setting the base frame 11; the telescopic device 12 is used to make the lifting unit 1 telescope in the vertical direction. By connecting the telescopic device 12 to the base frame 11, the stability of the lifting unit 1 can be improved when it is telescoped in the vertical direction. The top frame is used to place the air duct 3. The top frame 13 and the base frame 11 are connected by using the telescopic device 12. When the air duct 3 is placed on the top frame, the lifting unit 1 can drive the top frame to move in the vertical direction through the telescopic device 12, thereby moving the air duct 3 up and down, reducing the workload of manually lifting the air duct 3 and installing it, and reducing the work intensity and the risk of high-altitude operations.

[0065] The base frame 11 is provided with universal wheels 14 , and the base frame 11 is in contact with the ground through the universal wheels 14 .

[0067] By providing the universal wheel 14, the base frame 11 can contact the ground through the universal wheel 14, thereby reducing the friction between the lifting unit 1 and the ground and increasing the service life of the lifting unit 1. Meanwhile, the universal wheel 14 can drive the lifting device 12 to move in any direction along the ground, thereby increasing the flexibility of the lifting device.

[0068] By providing four universal wheels 14 and arranging the universal wheels 14 on both sides of the base frame 11 relatively, the balance of the lifting unit 1 can be improved. At the same time, when some universal wheels 14 are damaged, the remaining universal wheels 14 can maintain normal operation, thereby improving the reliability of the lifting unit 1.

[0069] The universal wheel 14 is detachably connected to the base frame 11 via a wheelbase adjustment mechanism 15 , and the wheelbase adjustment mechanism 15 is used to adjust the distance of the universal wheel 14 along the width direction of the base frame 11 .

[0070] Furthermore, the wheelbase adjustment mechanism 15 is a galvanized steel pipe, the universal wheel 14 is fixedly mounted on one end of the galvanized steel pipe, and the galvanized steel pipe can be connected to the base frame 11 through a pin hole.

[0071] By connecting the universal wheels 14 to the base frame 11 via the wheelbase adjustment mechanism 15, the spacing between the relatively arranged universal wheels 14 can be adjusted to meet the needs of different working scenarios, thereby improving the flexibility of the lifting unit 1. At the same time, by setting the wheelbase adjustment mechanism 15, the wheelbase can be quickly adjusted according to actual needs without replacing or redesigning the universal wheels 14, which makes the operation more convenient. By setting the adjustment mechanism 15 to adjust the distance of the universal wheels 14 along the width direction of the base frame 11, when the wheelbase is lengthened, the lifting unit 1 has better stability during operation.

[0072] The ratio of the horizontal distance between the universal wheels 14 relatively arranged along the width direction of the base frame 11 to the width of the base frame 11 is 1-2, and can be set to 2 or 1.5 according to actual needs.

[0073] By setting an adjustable range of the distance between the universal wheels 14 , it is helpful to distribute the load more evenly, and reduce the possibility of local excessive wear or damage of the universal wheels 14 due to uneven load.

[0074] The two lifting units 1 are connected via the top frame 13 .

[0075] By arranging the lifting units 1 to be connected via the top frame 13, the probability that the top frames 13 of the two lifting units 1 can be kept at the same horizontal plane when the two lifting units 1 are extended or retracted is increased, thereby improving the stability during construction.

[0076] Furthermore, the top frames 13 may be connected via bolts and nuts.

[0077] The top frame 13 is provided with two limiting parts 16 . The limiting parts 16 are relatively arranged at two side edges of the top frame 13 along the length direction. The limiting parts 16 are used to limit the movement of the air duct 3 .

[0078] When the air duct 3 is placed on the top frame 13, the axial direction of the air duct 3 is in the same direction as the length of the top frame 13. By providing limit portions 16 on both sides of the top frame 13, the possibility of preventing the air duct 3 from rolling on the top frame 13 is increased, thereby improving safety during construction.
