Technical Field

[0001] The utility model belongs to the technical field of auxiliary appliances for screw blowers, and particularly relates to a loading base for a screw blower. Background Technique

[0002] A screw blower is a commonly used industrial blower device. It generates wind pressure through the rotation of screws and is used to transport air or gas. When a screw blower is in use, a corresponding loading base is often installed at its bottom.

[0003] Most of the existing loading bases for screw blowers can only play a role in fixing the screw blower. However, since the ground where the loading base is located often has a certain degree of unevenness, the screw blower fixed by the loading base is likely to tilt due to the uneven placement surface, which is likely to cause certain abnormal noises when the screw blower is in use and is not conducive to use.

[0004] Therefore, a loading base for a screw blower is needed to solve the problem in the existing technology that since the ground where the loading base is located often has a certain degree of unevenness, the screw blower fixed by the loading base is likely to tilt due to the uneven placement surface.

[0008] It is further worth noting that second gears are fixedly sleeved at both ends of the outer circumference of the rotating rod, positioning strips are fitted on the surfaces of both sides of the second gear, and a threaded plate is fixed at the middle position of two adjacent positioning strips.

[0009] It should be further explained that three fixed blocks are fixed on the top surface of the connecting plate at the middle position of the two threaded plates, and a second threaded rod is rotatably connected through the middle position of one of the fixed blocks, and the second threaded rod is connected to the two threaded plates through a threaded structure.

Specific embodiments

[0020] Please refer to Figures 1 - 4 , the present utility model provides a loading base for a screw blower, including a support 1, a connecting plate 2 is arranged on the top of the support 1, a mounting plate 3 is arranged on the top of the connecting plate 2, a screw blower body 4 is fixed on the top of the mounting plate 3, a rotating shaft 5 is rotatably connected to the middle position of the top surface of the support 1, the top of the rotating shaft 5 is fixed to the bottom surface of the connecting plate 2, a rotating rod 13 is rotatably connected to one side of the top surface of the connecting plate 2, a connecting sleeve 14 is fixedly sleeved on the middle position of the outer peripheral surface of the rotating rod 13, the top of the connecting sleeve 14 is fixed to the bottom surface of the mounting plate 3, an abutting groove 15 is opened on the other side of the top surface of the connecting plate 2, a sliding block 16 is slidably inserted into the inside of the abutting groove 15, a first threaded rod 19 is threadedly connected to the surface of one side of the connecting plate 2, one side of the first threaded rod 19 extends into the inside of the adjacent abutting groove 15 and is rotatably connected to the surface of the sliding block 16, a connecting strip 17 is fixed to the top of the sliding block 16, a plurality of movable rods 18 are hinged to the top of the connecting strip 17, the top of the movable rods 18 is hinged to the bottom surface of the mounting plate 3, a bubble level 7 is fixed to the surface of one end of the mounting plate 3, by rotating the rotating shaft 5 until it forms a certain included angle with the inclined surface of the placement position, and then by rotating the first threaded rod 19, the mounting plate 3 can change its angle, so that the mounting plate 3 can drive the screw blower body 4 to be adjusted to a horizontal state, thereby avoiding the occurrence of abnormal noise during the operation of the screw blower body 4 due to inclination.

[0021] Furthermore, as Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically stating that a first gear 6 is fixedly sleeved on the outer peripheral surface of the rotating shaft 5. One end of the first gear 6 is meshed with a rack 8. One side of the top surface of the support 1 is fixedly provided with a hydraulic cylinder 9. The output end of the hydraulic cylinder 9 is fixed to the surface of the rack 8. By controlling the extension of the output end of the hydraulic cylinder 9, the rack 8 can move horizontally, so that the rack 8 can engage with the first gear 6 to enable the rotating shaft 5 to rotate.

[0022] Furthermore, as Figure 3 shown, it is worth specifically stating that second gears 20 are fixedly sleeved at both ends of the outer peripheral surface of the rotating rod 13. Positioning strips 21 are attached to the surfaces on both sides of the second gears 20. A threaded plate 23 is fixed at the middle position between two adjacent positioning strips 21. By the two positioning strips 21 abutting against the second gears 20, the rotating rod 13 can no longer rotate, so as to limit the angular state of the mounting plate 3.

[0023] Furthermore, as Figure 3 shown, it is worth specifically stating that three fixing blocks 22 are fixed at the middle position of the top surface of the connecting plate 2 between the two threaded plates 23. A second threaded rod 24 is rotatably connected through the middle position of one of the fixing blocks 22. The second threaded rod 24 is connected to the two threaded plates 23 through a threaded structure. Limiting shafts 25 are fixedly penetrated through the middle positions of the other two fixing blocks 22. The limiting shafts 25 are slidably connected to the two threaded plates 23. The two limiting shafts 25 can limit the movement track of the threaded plate 23. And the external thread structures on both sides of the outer peripheral surface of the second threaded rod 24 are arranged in opposite directions, so that the threaded plate 23 can move horizontally in the direction of approaching or moving away from each other under the cooperation of the internal thread structure on its inner wall and the corresponding external thread structure on the outer peripheral surface of the second threaded rod 24, enabling the positioning strips 21 to move.

[0024] This solution has the following working process: During actual use, when the user installs and places the screw blower body 4 at the corresponding position through the support 1, the bubble level 7 can be used to observe whether the mounting plate 3 is in a horizontal state. If it is not in a horizontal state, first extend the output end of the control hydraulic cylinder 9, so that the rack 8 can move horizontally, so that the rack 8 can engage with the first gear 6, causing the rotating shaft 5 to rotate, so that the connecting plate 2 can drive the mounting plate 3 to rotate a certain angle, so that the mounting plate 3 can form a certain angle with the inclined surface. Subsequently, rotate the first threaded rod 19 so that it extends under the cooperation of the threaded structure between it and the connecting plate 2, so that the sliding block 16 can move horizontally under the resistance of the resisting groove 15 and the drive of the first threaded rod 19, so that the connecting bar 17 can move horizontally, so that the movable rod 18 can change its angle, so that the mounting plate 3 can change its angle, so that the mounting plate 3 can be adjusted to a horizontal state, so as to ensure that the mounting plate 3 is in a horizontal state when supporting and fixing the screw blower body 4, so as to avoid abnormal noises that may occur due to inclination during the operation of the screw blower body 4. When the second threaded rod 24 is rotated, due to the reverse setting of the external thread structures on both sides of the outer peripheral surface of the second threaded rod 24 and the two limiting shafts 25 can limit the movement trajectory of the threaded plate 23, the threaded plate 23 moves horizontally in the direction of approaching each other under the cooperation of the internal thread structure on its inner wall and the corresponding external thread structure on the outer peripheral surface of the second threaded rod 24, so that the positioning strip 21 can move horizontally in the direction of approaching each other. By the two positioning strips 21 abutting against the second gear 20, the rotating rod 13 can no longer rotate, so as to limit the angular state of the mounting plate 3, so as to improve the stability of the mounting plate 3.

[0025] According to the above working process, it can be known that: by rotating the rotating shaft 5 until it forms a certain included angle with the inclined surface of the placement position, and then rotating the first threaded rod 19, the mounting plate 3 can change its angle, so that the mounting plate 3 can drive the screw blower body 4 to be adjusted to a horizontal state, so as to avoid abnormal noises that may occur due to inclination during the operation of the screw blower body 4, thereby improving the use stability of the device. By rotating the second threaded rod 24, the two positioning strips 21 can move towards the second gear 20 until they abut against each other, so as to limit the angular state of the mounting plate 3 after adjustment, so as to improve the stability of the mounting plate 3, thereby improving the practicability of the device.

[0026] Further, as Figure 4As shown, it is worth explaining in detail that a limit groove 10 is provided on the top surface of the support 1 at the position of the bottom of the rack 8, an embedded shaft 11 is fixed inside the limit groove 10, and a limit sleeve 12 is provided on the sliding sleeve on the outer circumference of the embedded shaft 11. The top of the limit sleeve 12 passes through the limit groove 10 and is fixed to the surface of the bottom of the rack 8. Since the limit sleeve 12 can only slide along the outer circumference of the embedded shaft 11 in the inner cavity of the limit groove 10, it can limit the movement trajectory of the rack 8 and make its horizontal movement process smoother.

[0027] In summary: by rotating the rotating shaft 5 until it forms a certain intersection angle with the inclined surface of the placement position, and then rotating the first threaded rod 19 to change the angle of the mounting plate 3, the mounting plate 3 can drive the screw blower body 4 to adjust to a horizontal state, thereby avoiding the occurrence of abnormal noise due to the tilt of the screw blower body 4 during operation, thereby improving the stability of the device, and rotating the second threaded rod 24 to allow the two positioning strips 21 to move toward the second gear 20 until the two collide with each other, thereby limiting the angle state of the mounting plate 3 after adjustment, thereby improving the stability of the mounting plate 3 and improving the practicality of the device, and since the limit sleeve 12 can only slide along the outer circumference of the embedded shaft 11 in the inner cavity of the limit groove 10, it can limit the movement trajectory of the rack 8, making its horizontal movement process smoother.

[0028] The hydraulic cylinder 9 can be purchased on the market. The hydraulic cylinder 9 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it is not repeated in the specification.
