Description

Technical Field

[0001] This utility model relates to the field of blower maintenance technology, and in particular to an auxiliary installation device for a lifting blower impeller. Background Technology

[0002] In industrial production workshops, the installation of fan impellers is a crucial step. During impeller transportation, due to the numerous pieces of equipment and passageways within the workshop, traditional methods rely on manual trolleys or simple cranes. Simple cranes often lack precise positioning and fine-tuning capabilities, making them inconvenient to operate in narrow workshop aisles and hindering the accurate transport of the impeller to the designated installation position. Furthermore, their lifting height is typically fixed, failing to accommodate varying installation heights. In addition, traditional impeller installation methods are extremely labor-intensive and inefficient. Lacking specialized auxiliary equipment, multiple workers are often required to work together to lift and repeatedly adjust the impeller's position and orientation during alignment and installation.

[0003] In summary, to meet the high-efficiency requirements for the transportation and installation of fan impellers within the workshop, an auxiliary installation device for fan impellers with both transportation mobility and height adjustment capability is needed. Utility Model Content

[0004] To address the issue of transporting and adjusting the impeller's installation height, this invention provides a lifting fan impeller auxiliary installation device.

[0005] This utility model provides an auxiliary installation device for a lifting fan impeller, including a vertically arranged fixed plate. One side of the fixed plate is provided with a clamping member for clamping the impeller shaft, and the other side of the fixed plate is connected to a driving member. The driving member can drive the fixed plate to move up and down in the vertical direction and move the impeller shaft clamped by the clamping member to a set height.

[0006] Furthermore, it also includes a gantry frame, which forms two vertical side walls and a crossbeam erected between the two side walls. The two side walls of the gantry frame are provided with inner sliding grooves facing each other. Multiple transverse support rods are provided between the two side walls of the gantry frame. One end of the support rod is connected to a fixed plate through a connecting block, and the other end of the support rod is equipped with a movable pulley. The axis of the movable pulley coincides with the axis of the support rod. The movable pulley rolls in the inner sliding groove and is limited in the inner sliding groove.

[0007] Furthermore, the bottom end of the gantry frame is provided with a movable component, which includes a base and casters disposed on the underside of the base, and the drive component is disposed on the base.

[0008] Furthermore, the driving component includes a vertically arranged lead screw, and a limiting component is fixedly connected to one side of the fixed plate connected to the driving component. The limiting component has a built-in nut and is movably connected to the lead screw through the built-in nut. The bottom end of the lead screw is connected to the base through a bearing, and the top end of the lead screw passes through the top surface of the crossbeam. The top end of the lead screw is provided with a power unit for driving the lead screw to rotate.

[0009] Furthermore, the power unit includes a turbine connected to the lead screw via a key, a drive worm gear connected in cooperation with the turbine, a wheel connected to the drive worm gear, the axis of the wheel gear being perpendicular to the axis of the lead screw, the wheel gear being disposed on the side of the crossbeam, the wheel gear driving the drive worm gear to rotate, thereby causing the turbine gear to drive the lead screw to rotate, and causing the fixed plate to move up and down along the lead screw.

[0010] Furthermore, the power unit includes a stepper motor, which is disposed on the top surface of the crossbeam, and the drive shaft of the stepper motor is connected to the top end of the lead screw.

[0011] Furthermore, the clamping member includes a cylindrical fixing head connected to the fixing plate. The fixing head has an internal groove at its center, which accommodates a clamping assembly. The clamping assembly includes multiple clamping blocks. A limit slide rod is slidably installed between the clamping blocks and the fixing head.

[0012] Furthermore, the clamping component also includes a chuck disposed on the fixed head. The chuck has a through hole in the center that communicates with the internal groove. The chuck has multiple sliding grooves in its circumference. Sliding claws are disposed in the sliding grooves. Multiple bolt through holes are opened on the sliding claws. The sliding claws are fixedly connected to the chuck by bolts.

[0013] Furthermore, the gripper extends away from the chuck to form a load-bearing convex arm.

[0014] Furthermore, an installation unit is provided between the fixing head and the chuck. The installation unit includes multiple installation slots opened along the circumference of the fixing head and multiple installation plates fixedly connected along the circumference of the chuck.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] 1. This utility model proposes a lifting-type auxiliary installation device for fan impellers. The casters in the moving parts allow the entire device to move freely within the workshop, improving the mobility of impeller transportation and enabling rapid transport of the device and impeller to the approximate installation location, thus increasing overall work efficiency. The design of the lead screw and limiting components in the driving parts, driven by the power unit, precisely controls the vertical movement of the fixing plate, thereby achieving precise adjustment of the height of the impeller shaft held by the clamping components. It can be flexibly adjusted according to the installation height requirements of different fan impellers.

[0017] 2. The present invention proposes a lifting fan impeller auxiliary installation device. The clamping blocks in the clamping assembly can adjust the clamping force on the impeller shaft through clamping bolts, which can adapt to impeller shafts of different diameters and ensure the stability of clamping. The sliding jaws on the chuck provide additional clamping points and load-bearing support. The protruding arms formed by the extension of the jaws enhance the load-bearing capacity and can be center-aligned, effectively preventing the impeller from shaking or falling off during installation.

[0018] 3. The lifting fan impeller auxiliary installation device proposed in this utility model has an installation unit between the fixed head and the chuck, which not only ensures the firmness of the connection between the two, but also facilitates the disassembly, repair or replacement of clamping parts of different specifications when needed, which is convenient and quick.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1 and Figure 2 This embodiment of a lifting fan impeller auxiliary installation device includes a vertically arranged fixing plate 1. One side of the fixing plate 1 is provided with a clamping member 5 for clamping the impeller shaft. The other side of the fixing plate 1 is connected to a driving member 4. The driving member 4 can drive the fixing plate 1 to move up and down in the vertical direction and move the impeller shaft clamped by the clamping member 5 to a set height.

[0029] Reference Figure 1 It also includes a gantry frame 2, which has two vertical side walls 201 and a crossbeam 202 mounted between the two side walls 201. The two side walls 201 of the gantry frame 2 are provided with inner sliding grooves 203 facing each other. Multiple transverse support rods 204 are provided between the two side walls 201 of the gantry frame 2. One end of the support rod 204 is connected to the fixed plate 1 through a connecting block 205. The other end of the support rod 204 is equipped with a movable pulley 206. The axis of the movable pulley 206 coincides with the axis of the support rod 204. The movable pulley 206 rolls in the inner sliding groove 203 and is limited in the inner sliding groove 203.

[0030] The bottom end of the gantry frame 2 is provided with a movable component 3, which includes a base 301 and a universal wheel 302 disposed on the lower side of the base 301. The driving component 4 is disposed on the base 301.

[0031] The gantry frame 2 serves as the supporting frame for the entire device, with its two vertical side walls 201 and crossbeam 202 forming a stable structure. The inner grooves 203, arranged opposite each other on the two side walls 201, provide guide tracks for the movement of subsequent components, ensuring the stability of the device during height adjustment. The dimensions of the inner grooves 203 are tightly fitted to the movable pulleys 206. The limiting effect of the pulleys within the inner grooves 203 prevents the fixed plate 1 from shifting horizontally, ensuring that the impeller remains on its predetermined position path during transportation and installation. The casters 302 on the underside of the base 301 of the moving component 3 have good load-bearing capacity and steering flexibility.

[0032] The driving component 4 includes a vertically arranged lead screw 401. A limiting component 402 is fixedly connected to one side of the fixed plate 1 connected to the driving component 4. The limiting component 402 has a built-in nut and is movably connected to the lead screw 401 through the built-in nut. The bottom end of the lead screw 401 is connected to the base 301 through a bearing. The top end of the lead screw 401 passes through the top surface of the crossbeam 202. A power unit for driving the lead screw 401 to rotate is provided at the top end of the lead screw 401.

[0033] The power unit includes a turbine connected to the lead screw 401 via a key, a drive worm gear connected in cooperation with the turbine, and a wheel 403 connected to the drive worm gear. The axis of the wheel 403 is perpendicular to the axis of the lead screw 401. The wheel 403 is disposed on the side of the crossbeam 202. The wheel 403 drives the drive worm gear to rotate, thereby causing the turbine to drive the lead screw 401 to rotate and causing the fixed plate 1 to move up and down along the lead screw 401.

[0034] As the core transmission component of the drive unit 4, the lead screw 401, with its vertically arranged structure, cooperates with the limiting member 402 on the fixed plate 1 to achieve height adjustment. The nut built into the limiting member 402 forms a lead screw 401-nut pair with the lead screw 401. This transmission method has high transmission efficiency and precise motion control capability. When the lead screw 401 rotates, the nut moves up and down on the lead screw 401, thereby driving the fixed plate 1 and its connected clamping member 5 to achieve vertical displacement. The bottom end of the lead screw 401 is connected to the base 301 through a bearing. The bearing can reduce the frictional resistance when the lead screw 401 rotates, while ensuring the stability of the lead screw 401 when subjected to large axial forces. The worm gear is connected to the lead screw 401 by a key, forming a worm gear transmission mechanism with the drive worm. The worm gear transmission has a large transmission ratio, which can achieve the effect of speed reduction and torque increase, allowing the operator to easily drive the worm by rotating the wheel 403, thereby driving the worm gear and the lead screw 401 to rotate. The axis of the impeller 403 is perpendicular to the axis of the lead screw 401 and is located on the side of the crossbeam 202 for easy operation. Simultaneously, the self-locking characteristic of the worm gear drive effectively prevents the lead screw 401 from rotating due to gravity or other external forces when the device is stopped, ensuring the stability of the impeller at the set height.

[0035] Reference Figure 5 The clamping member 5 includes a cylindrical fixing head 501 connected to the fixing plate 1. The fixing head 501 has an internal groove 502 at its center. The internal groove 502 accommodates a clamping assembly. The clamping assembly includes multiple clamping blocks 503. A limit slide rod 504 is slidably installed between the clamping blocks 503 and the fixing head 501. The fixing head 501 is rotatably connected to multiple clamping bolts 505. One end of each clamping bolt 505 abuts against the clamping block 503.

[0036] Reference Figure 4 The clamping member 5 also includes a chuck 506 disposed on the fixed head 501. The chuck 506 has a through hole in the center that communicates with the internal groove 502. The chuck 506 has a plurality of sliding grooves 507 in the circumference. Sliding claws 508 are disposed in the sliding grooves 507. A plurality of bolt through holes 509 are opened on the sliding claws 508. The sliding claws 508 are fixedly connected to the chuck 506 by bolts.

[0037] The gripper extends away from the chuck 506 to form a load-bearing convex arm 510.

[0038] Reference Figure 3 , Figure 4 and Figure 5An installation unit 6 is provided between the fixing head 501 and the chuck 506. The installation unit 6 includes a plurality of installation slots 601 opened around the fixing head 501 and a plurality of installation plates 602 fixedly connected around the chuck 506. The installation plates 602 are inserted into the corresponding installation slots 601 and are fixed in the installation slots 601 by bolts.

[0039] The internal groove 502 at the center of the cylindrical fixing head 501 provides installation space for the clamping assembly. Multiple clamping blocks 503 are slidably connected to the fixing head 501 within the internal groove 502 via limiting slide rods 504. The limiting slide rods 504 restrict the movement direction of the clamping blocks 503, allowing them to slide only radially. Clamping bolts 505 are circumferentially mounted on the fixing head 501. When the clamping bolts 505 are tightened, one end of the clamping bolt 505 abuts against the clamping block 503, pushing the clamping block 503 towards the center, thereby clamping the impeller shaft. Impeller shafts of different diameters can be reliably clamped by adjusting the tightening degree of the clamping bolts 505. The surface of the clamping block 503 is made of anti-slip rubber to increase friction with the impeller shaft.

[0040] The chuck 506 and sliding jaws 508 work together. The through hole in the center of the chuck 506 communicates with the internal groove 502 of the fixed head 501, facilitating the passage and installation of the impeller shaft. Multiple sliding grooves 507 around the chuck 506 house the sliding jaws 508, and bolt through holes 509 on the sliding jaws 508 are used for bolt-fixed connection with the chuck 506. When installing the impeller, first pass the impeller shaft through the internal groove 502 of the fixed head 501 and the through hole of the chuck 506. Then, adjust the position of the sliding jaws 508 within the sliding grooves 507 according to the size of the impeller shaft, ensuring the shaft center is in the center position. Finally, fix the sliding jaws 508 to the chuck 506 with bolts. The load-bearing protrusion 510 formed by the jaws extending away from the chuck 506 improves the clamping load-bearing capacity.

[0041] The installation unit 6 facilitates the disassembly of the chuck 506 and the fixing head 501 for replacement and maintenance.
