[0015] A method for using a pre-filter assembly device comprises the following steps:

[0016] S1. First, insert the base of the pre-filter into the positioning sleeve. The inner wall structure of the positioning sleeve is determined according to the shape of the pre-filter base and can be replaced. When installing, snap the installation grooves together with the positions of the reinforcement blocks to position the positioning sleeve at the top of the mounting seat. When assembling, snap the base into the interior of the positioning sleeve.

[0017] S2. By pushing one of the positioning rods, when one positioning rod moves forward, the tooth grooves on its outer surface will mesh with the connecting gear. At the same time, the connecting gear and the tooth grooves on the outer surface of the other positioning rod are also meshed. Therefore, only pushing one positioning rod can drive the other positioning rod to move symmetrically at the same time. Loosen the pull ring, and under the rebound effect of the strong spring, the two fixing blocks will be pushed. The two fixing blocks are pushed closer to the middle under the elastic push of the strong spring, and finally mesh with the two slots, thereby completing the clamping installation of the positioning sleeve;

[0018] S3, start the electric telescopic rod to retract it, thereby driving the two clamping rods to move toward the middle part at the same time, and while moving, driving the clamping blocks installed on the two fixing frames to move toward the middle position until the upper parts of the pre-filter to be assembled are clamped;

[0019] S4. By starting two hydraulic cylinders at the same time, the two fixed rods can be lifted and lowered at the same time. By starting the driving motor, its output shaft drives the active rotating wheel to rotate. Under the connection of the connecting belt, the rotating ring rotates at the same time. While rotating, the hydraulic cylinders descend at the same time, and finally the purpose of rotating downward assembly is achieved.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When in use, the inner wall structure of the positioning sleeve is determined according to the shape of the pre-filter base and can be replaced. When installing, the installation groove is snapped together with the position of the reinforcement block to position the positioning sleeve on the top of the mounting seat. When assembling, the base is snapped into the inside of the positioning sleeve. By pushing one of the positioning rods, the other positioning rod is driven to move symmetrically at the same time. After the positions of the block and the slot are matched, the pull ring can be loosened. At this time, under the rebound action of the strong spring, the two fixing blocks will be pushed. The two fixing blocks are pushed closer to the middle under the elastic push of the strong spring, and finally snapped with the two slots, thereby completing the snap-in installation of the positioning sleeve. Then, when assembling the pre-filter, there is no need to manually position its base, which can reduce labor consumption;

[0022] 2. When in use, by starting two hydraulic cylinders at the same time, the two fixed rods can be lifted and lowered at the same time. This is because the upper parts of the pre-filter are of different heights and need to be moved to a suitable height for installation with the base. By starting the drive motor, the output shaft is rotated, thereby driving the plug shaft to rotate inside the jack, and then driving the active wheel to rotate. At this time, under the connection of the connecting belt, the rotating ring will rotate at the same time. Since the rotating ring rotates in an interlocking manner inside the fixed ring, the rotating ring has good stability during rotation, so that the assembly of the upper spiral mounting parts of the pre-filter can be completed. Among them, since the active rotating groove and the driven rotating groove are connected by a soft connecting belt, the jamming caused by the rotation can be avoided. While rotating, the hydraulic cylinder descends at the same time, and finally the purpose of rotating downward assembly is achieved;

[0023] 3. When in use, the electric telescopic rod is started to shrink, thereby driving the two clamping rods to move toward the middle part at the same time, and the clamping blocks installed on the two fixing frames are also driven to move toward the middle position during the movement, until the upper parts of the pre-filter to be assembled are clamped, wherein the anti-slip spikes can prevent the parts from slipping during assembly, thereby replacing the manual screwing and reducing the manual links, and the movable block is made to slide inside the movable groove, and the slider is made to slide inside the slide groove at the same time, so that the two clamping rods can maintain balance during the clamping movement.

[0036] In this embodiment, when in use, first, the base of the pre-filter is inserted into the positioning sleeve 112. The inner wall structure of the positioning sleeve 112 is determined according to the shape of the pre-filter base and can be replaced. Then, when installing, the mounting groove 113 is snapped together with the position of the reinforcement block 115 to position the positioning sleeve 112 on the top of the mounting seat 101. When assembling, the base is snapped into the interior of the positioning sleeve 112, and the positioning rods 106 are pushed through one of them. When one positioning rod 106 moves forward, the tooth groove 104 opened on its outer surface will mesh with the connecting gear 103. At the same time, the connecting gear 103 and the tooth groove 104 opened on the outer surface of the other positioning rod 106 are engaged. 4 are also engaged with each other, so only pushing one positioning rod 106 can drive the other positioning rod 106 to move symmetrically at the same time.

[0037] Embodiment 2: Figure 1 - Figure 8 As shown, hydraulic cylinders 5 are arranged near both sides of the top of the fixed chassis 4, and a rotating assembly 2 is fixedly connected between the tops of the two hydraulic cylinders 5. The rotating assembly 2 includes two fixed rods 201, and the two fixed rods 201 are fixedly installed on the tops of the two hydraulic cylinders 5 respectively. A fixed ring 202 is fixedly connected between the two fixed rods 201, and a rotating ring 203 is rotatably connected to the inner wall of the fixed ring 202. A driven rotating groove 204 is provided on the outer surface of the rotating ring 203 near the top. A plug hole 207 is provided on the top of one of the fixed rods 201, and an insertion shaft 206 is rotatably connected to the inner wall of the plug hole 207. A driving rotating wheel 209 is fixedly connected to the top of the insertion shaft 206, and a driving rotating groove 210 is provided on the outer surface of the driving rotating wheel 209. A connecting belt 208 is movably connected between the inner wall of the driving rotating groove 210 and the inner wall of the driven rotating groove 204. A driving motor 205 is provided at the bottom of one of the fixed rods 201, and the output shaft of the driving motor 205 is fixedly connected to the bottom of the insertion shaft 206.

[0038] In this embodiment, when in use, by starting two hydraulic cylinders 5 at the same time, the two fixed rods 201 can be lifted and lowered at the same time. This is because the upper parts of the pre-filter have different heights and need to be moved to a suitable height for installation with the base. The function of the fixed chassis 4 is to improve stability. The most commonly used method during assembly is rotational installation. By starting the drive motor 205, the output shaft thereof rotates, thereby driving the plug shaft 206 to rotate inside the plug hole 207, thereby driving the active rotating wheel 209 to rotate. At this time, under the connection of the connecting belt 208, the rotating ring 203 will rotate at the same time. Since the rotating ring 203 rotates in an interlocking manner inside the fixed ring 202, the rotating ring 203 has good stability during rotation, thereby completing the assembly of the upper spiral mounting parts of the pre-filter. Since the active rotating groove 210 and the driven rotating groove 204 are connected by a soft connecting belt 208, the jamming caused during rotation can be avoided. While rotating, the hydraulic cylinder 5 descends at the same time, and finally the purpose of rotating downward assembly is achieved.

[0039] Embodiment three: Figure 1 - Figure 8 As shown, a clamping assembly 3 is fixedly connected between the inner walls of the rotating ring 203, and the clamping assembly 3 includes a support rod 301, a movable groove 303 is opened on the top of the support rod 301, and a slide groove 302 is opened on the inner bottom surface of the movable groove 303, and two sliders 304 are slidably connected to the inner wall of the slide groove 302, and the tops of the two sliders 304 are fixedly connected with movable blocks 305, and the outer surfaces of the two movable blocks 305 are slidably connected to the inner walls of the two movable grooves 303 respectively, and the tops of the two movable blocks 305 are fixedly connected with clamping rods 306, and an electric telescopic rod 307 is arranged between the two clamping rods 306 near one end, and the opposite side of the two clamping rods 306 is fixedly connected near the other end. A fixing frame 308 is fixedly connected to the opposite side of the two fixing frames 308, and a clamping block 309 is fixedly connected to the opposite side of the two clamping blocks 309. A plurality of anti-slip spikes 310 are fixedly connected to the opposite side of the two clamping blocks 309, and the two clamping blocks 309 are symmetrically arranged.

[0040] In this embodiment, when in use, an electric telescopic rod 307 with its own mobile battery is selected, and there is no need to electrically connect to an external power source. The driving motor 205, the electric telescopic rod 307 and the hydraulic cylinder 5 are all connected to an external control system via Bluetooth, so that the start, stop and operation can be controlled by the external control system. By starting the electric telescopic rod 307 to shrink it, the two clamping rods 306 are driven to move toward the middle part at the same time. During the movement, the clamping blocks 309 installed on the two fixing frames 308 are driven to move toward the middle position until the upper parts of the pre-filter to be assembled are clamped. The anti-slip spikes 310 can prevent the parts from slipping during assembly, thereby replacing manual screwing and reducing the manual process. The movable block 305 is made to slide inside the movable groove 303, and the slider 304 is made to slide inside the slide groove 302, so that the two clamping rods 306 can maintain balance during the clamping movement.

[0041] The method of use and working principle of this device: When in use, first, insert the base of the pre-filter into the positioning sleeve 112. The inner wall structure of the positioning sleeve 112 is determined according to the shape of the pre-filter base and can be replaced. Then, when installing, the mounting groove 113 is snapped together with the position of the reinforcement block 115 to position the positioning sleeve 112 on the top of the mounting seat 101. When assembling, just snap the base into the inside of the positioning sleeve 112, and push the positioning rod 106 through one of them. When one positioning rod 106 moves forward, the tooth groove 104 on its outer surface will mesh with the connecting gear 103. At the same time, the connecting gear 103 and the tooth groove 104 on the outer surface of the other positioning rod 106 are also engaged. The two fixing blocks 109 are engaged with each other, so only pushing one positioning rod 106 can drive the other positioning rod 106 to move symmetrically at the same time. Through the limiting sleeve of the fixing block 109, the two positioning rods 106 can slide in parallel without tilting. After the positions of the card block 110 and the card slot 114 are matched, the pull ring 107 can be loosened. At this time, under the rebound effect of the strong spring 108, the two fixing blocks 109 will be pushed. The two fixing blocks 109 are pushed toward the middle under the elastic push of the strong spring 108, and finally engage with the two card slots 114, thereby completing the engagement installation of the positioning sleeve 112. Then, when assembling the pre-filter, there is no need to manually position its base, which can reduce labor consumption. When in use, choose a mobile battery with its own battery. The electric telescopic rod 307 does not need to be electrically connected to an external power source, and the driving motor 205, the electric telescopic rod 307 and the hydraulic cylinder 5 are connected to the external control system via Bluetooth, so that the start, stop and operation can be controlled by the external control system. By starting the electric telescopic rod 307 to shrink it, the two clamping rods 306 are driven to move toward the middle part at the same time, and the clamping blocks 309 installed on the two fixing frames 308 are driven to move toward the middle position during the movement until the upper parts of the pre-filter to be assembled are clamped, wherein the anti-slip spikes 310 can prevent the parts from slipping during assembly, and the movable block 305 is made to slide inside the movable groove 303, and the slider 304 is made to slide inside the slide groove 302, so that the two clamping rods 306 can maintain balance during clamping and movement. When in use, by starting two hydraulic cylinders 5 at the same time, the two fixed rods 201 can be lifted and lowered at the same time. This is because the upper parts of the pre-filter have different heights and need to be moved to a suitable height to facilitate installation with the base. The function of the fixed chassis 4 is to improve stability. The most commonly used method during assembly is rotational installation. By starting the drive motor 205 to rotate its output shaft, the plug shaft 206 is driven to rotate inside the socket 207, thereby driving the active runner 209 to rotate. At this time, under the connection of the connecting belt 208, the rotating ring 203 will rotate at the same time. Since the rotating ring 203 rotates in an interlocking manner inside the fixed ring 202,Then the rotating ring 203 has good stability when rotating, wherein, since the active rotating groove 210 and the driven rotating groove 204 are connected by the soft connecting belt 208, the jamming during the rotation can be avoided. While rotating, the hydraulic cylinder 5 simultaneously descends, and finally the purpose of rotating downward assembly is achieved.

The model is selected according to the actual use, so the control method and wiring arrangement of the drive motor 205, the electric telescopic rod 307 and the hydraulic cylinder 5 are no longer explained in detail.
