Description

Technical Field

[0001] This utility model belongs to the field of blade installation technology, specifically an auxiliary installation device for the blades of an industrial ceiling fan. Background Technology

[0002] Industrial ceiling fans are rapidly gaining popularity due to their inherent advantages in cooling large factory buildings, including a wide coverage area per unit and high user comfort. Generally, industrial ceiling fans are large, with blades ranging from 3 to 4 meters in length. From a manufacturing process perspective, the blades are typically made of extruded aluminum alloy, with the hollow blades directly fitted into blade connectors and secured with bolts.

[0003] A Chinese patent with publication number CN111963488A discloses an auxiliary installation device for the blades of an industrial ceiling fan, including a rectangular base frame, columns fixed on the front and rear sides of the base frame, a horizontal support beam fixed at the upper end of the columns, hinge shafts at both ends of the horizontal support beam, the two ends of the hinge shafts being inserted and fixed on the horizontal support beam, a right lead screw and a left lead screw respectively formed at both ends of the adjustment shaft, the outer ends of the right lead screw and the left lead screw being hinged to a support frame, a right support rod and a left support rod respectively inserted on the hinge shafts at both ends of the horizontal support beam, a right guide groove and a left guide groove respectively formed at the lower part of the right support rod and the left support rod, a right drive block and a left drive block respectively screwed onto the right lead screw and the left drive block, a right support shaft and a left support shaft respectively formed at both ends of the right drive block and the left drive block, the right support shaft and the left support shaft being inserted into the right guide groove of the right support rod and the left guide groove of the left support rod respectively.

Multiple springs are sleeved on the outer sides of each vertical rod, and the two ends of each spring are respectively fixedly connected to two adjacent arc-shaped blocks.

[0016] This utility model provides an auxiliary installation device for the blades of an industrial ceiling fan. It features an arc-shaped block and a bidirectional lead screw. A third motor is activated, and its output shaft drives the bidirectional lead screw to rotate. The lead screw then moves a movable frame to a suitable position, allowing the two ends of the blades to be placed on the arc-shaped block. The blades are then placed sequentially on the arc-shaped block. Next, two rotating blocks are rotated, causing a threaded rod to rotate.

The rotating rod drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear drives a reciprocating screw to rotate, which in turn drives a lifting rod to move upward. The lifting rod then drives a fixed frame to move upward until it reaches a suitable height.

[0018] This utility model provides an auxiliary installation device for the blades of an industrial ceiling fan. By setting a fixed plate and a rotating plate, in order to prevent the blades from slipping off from both sides, a fixed plate and a rotating plate are respectively set at both ends of the fixing frame for the protection of the blades. When it is necessary to pick up the material, the limiting block is rotated in the opposite direction. The limiting block rotates 90°, thereby releasing the fixing of the rotating plate, and the rotating plate flips over, so that the material can be picked up quickly. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Specific implementation examples are given below.

[0030] Please see Figures 1-6 This utility model provides an auxiliary installation device for the blades of an industrial ceiling fan, including a base 1. An adjustment mechanism is provided above the base 1, and a fixed frame 3 is provided above the adjustment mechanism. The adjustment mechanism is used to adjust the height of the fixed frame 3. A bidirectional lead screw 33 is rotatably connected between the inner walls of the fixed frame 3 via bearings. Two movable frames 32 are threadedly connected to the bidirectional lead screw 33. Two vertical rods 36 are fixedly connected between the inner walls of each movable frame 32. Multiple arc-shaped blocks 35 are slidably connected to the two vertical rods 36 on the same side. Multiple springs 37 are sleeved on the outer side of each vertical rod 36. The two ends of each spring 37 are respectively fixedly connected to two adjacent arc-shaped blocks 35. A threaded rod 38 is threadedly connected to the top of each movable frame 32. A rotating block 39 is fixedly connected to the top of each threaded rod 38. The bottom of each threaded rod 38 is rotatably connected to the top of the uppermost arc-shaped block 35 via bearings. A third motor 31 is fixedly connected to the side wall of the fixed frame 3. The output shaft of the third motor 31 is fixedly connected to one end of the bidirectional lead screw 33.

[0031] To address the inconvenience of simultaneously hoisting multiple blades during operation, the third motor 31 is activated during installation. Its output shaft drives the bidirectional lead screw 33, which in turn moves the movable frame 32 until it reaches a suitable position. This allows the blades to be placed on the curved blocks 35 one by one. The curvature of the blades aligns with that of the curved blocks 35, which are made of elastic rubber. This elasticity not only supports and holds the blades but also prevents wear on them. Then, the blades are rotated... Rotating the two rotating blocks 39 causes the threaded rod 38 to rotate, which in turn causes the uppermost arc-shaped block 35 to move downwards. This changes the force on the spring 37, causing it to contract. The arc-shaped block 35 then slides on the vertical rod 36 until multiple blades are clamped and fixed simultaneously, facilitating the simultaneous hoisting of multiple blades. When material needs to be removed, rotating the rotating blocks 39 in the opposite direction causes the threaded rod 38 to rotate in the opposite direction, which in turn causes the arc-shaped block 35 to move upwards. The spring 37 then returns to its original position, and the blade can be removed from between the two arc-shaped blocks 35.

[0032] Furthermore, such as Figure 1 and Figure 6 As shown, a fixing plate 4 is fixedly connected to one side wall of the fixing frame 3, and a rotating plate 41 is rotatably connected to the other side wall of the fixing frame 3 via a rotating shaft. Two fastening bolts 43 are fixedly connected to the side wall of the fixing frame 3, and a limit block 42 is threadedly connected to the outer wall of each fastening bolt 43. The limit block 42 is used to fix the rotating plate 41.

[0033] During operation, in order to prevent the blades from slipping off from both sides, the fixed plate 4 and the rotating plate 41 are respectively set at both ends of the fixed frame 3 to protect the blades. When it is necessary to pick up the material, the limiting block 42 is rotated in the opposite direction. The limiting block 42 rotates 90°, thereby releasing the fixing of the rotating plate 41. The rotating plate 41 flips over, so that the material can be picked up quickly.

[0034] Furthermore, such as Figure 2 and Figure 5 As shown, the adjustment mechanism includes a lifting rod 21, the top of which is fixed to the bottom of the fixed frame 3. A fixed rod 2 is slidably connected to the outer side of the lifting rod 21 via a limiting rod 23. A reciprocating screw 22 is rotatably connected to the bottom inner wall of the fixed rod 2 via a bearing. The lifting rod 21 is threaded to the outer side of the reciprocating screw 22. A driving mechanism is provided at the bottom end of the reciprocating screw 22.

[0035] During operation, the height of the mounting bracket 3 needs to be adjusted to align the blades with the head of the ceiling fan, facilitating installation. By activating the drive mechanism, the reciprocating screw 22 rotates, which in turn drives the lifting rod 21 upwards, which in turn drives the mounting bracket 3 upwards until it reaches the appropriate height.

[0036] Furthermore, such as Figure 5 As shown, the driving mechanism includes a first bevel gear 24 fixed to the bottom end of the reciprocating lead screw 22, an L-shaped plate 28 fixed to the outer wall of the fixed rod 2, a second motor 27 fixed to the L-shaped plate 28, a rotating rod 26 fixed to the output shaft of the second motor 27, and a second bevel gear 25 fixed to one end of the rotating rod 26. The first bevel gear 24 meshes with the second bevel gear 25.

[0037] During operation, in order to quickly drive the reciprocating screw 22 to rotate, the second motor 27 is turned on. The output shaft of the second motor 27 drives the rotating rod 26 to rotate, which in turn drives the second bevel gear 25 to rotate. The second bevel gear 25 drives the first bevel gear 24 to rotate, which in turn drives the reciprocating screw 22 to rotate, thus realizing the rotation of the reciprocating screw 22.

[0038] Furthermore, such as Figure 1 As shown, two mounting plates 12 are fixed to the top of the base 1. A first motor 13 is fixed to the side wall of one of the mounting plates 12. The output shaft of the first motor 13 is rotatably connected to the mounting plate 12 through a bearing. The bottom end of the fixing rod 2 is fixed to the output shaft of the first motor 13.

[0039] During operation, in order to facilitate the installation of the blades on the arc block 35, the first motor 13 needs to be turned on. The output shaft of the first motor 13 drives the fixed rod 2 to rotate, the fixed rod 2 drives the lifting rod 21 to rotate, the lifting rod 21 drives the fixed frame 3 to rotate, and the fixed frame 3 drives the arc block 35 to rotate, thereby lowering the height of the arc block 35 and facilitating the installation of the blades.

[0040] Furthermore, such as Figure 2 As shown, each of the four corners of the base 1 is equipped with a movable wheel; each of the four corners of the base 1 is provided with an anchor rod 11.

[0041] During operation, the base 1 is moved to a designated position by the installation of casters, and the base 1 is fixed by the installation of anchor rods 11 to prevent the device from tipping over during the rotation or lifting of the lifting rod 21.

[0042] Furthermore, such as Figure 5As shown, two limiting rods 23 are symmetrically fixed to the outer wall of the lifting rod 21, and the limiting rods 23 are slidably connected to the inside of the fixed rod 2 through the limiting groove.

[0043] During operation, by setting a limit rod 23, when the lifting rod 21 moves, the limit rod 23 slides in the limit groove, and the lifting rod 21 is limited to move in the axial direction by the limit rod 23.

[0044] Furthermore, such as Figure 3 As shown, two guide rods 34 are fixedly connected between the inner sidewalls of the fixed frame 3, and the movable frame 32 is slidably connected to the two guide rods 34.

[0045] During operation, by setting the guide rod 34, the moving frame 32 slides on the guide rod 34 during movement, and the guide rod 34 limits the movement of the moving frame 32 in the horizontal direction.

[0046] Working Principle: To address the inconvenience of simultaneously hoisting multiple blades, during installation, the third motor 31 is activated. The output shaft of the third motor 31 drives the bidirectional lead screw 33 to rotate, which in turn moves the moving frame 32 until it reaches a suitable position. This allows the blades to be placed on the curved blocks 35 one by one. The curvature of the blades aligns with that of the curved blocks 35. The curved blocks 35 are made of elastic rubber, which not only supports and holds the blades but also prevents wear on them. Then, the blades are placed individually... Rotating the two rotating blocks 39 causes the threaded rod 38 to rotate, which in turn causes the uppermost arc-shaped block 35 to move downwards. This changes the force on the spring 37, causing it to contract. The arc-shaped block 35 then slides on the vertical rod 36 until multiple blades are clamped and fixed simultaneously, facilitating the simultaneous hoisting of multiple blades. When material needs to be removed, rotating the rotating blocks 39 in the opposite direction causes the threaded rod 38 to rotate in the opposite direction, which in turn causes the arc-shaped block 35 to move upwards. The spring 37 then returns to its original position, and the blade can be removed from between the two arc-shaped blocks 35.

[0047] To prevent the blades from slipping off from both sides, the fixed frame 3 is equipped with a fixed plate 4 and a rotating plate 41 at both ends to protect the blades. When material needs to be removed, the limiting block 42 is rotated in the opposite direction. The limiting block 42 rotates 90°, thereby releasing the fixing of the rotating plate 41. The rotating plate 41 flips over, allowing for quick material removal.

[0048] The height of the mounting bracket 3 needs to be adjusted to allow the blades to be aligned with the head of the ceiling fan for easier installation. By turning on the second motor 27, the output shaft of the second motor 27 drives the rotating rod 26 to rotate, which in turn drives the second bevel gear 25 to rotate. The second bevel gear 25 then drives the first bevel gear 24 to rotate, which in turn drives the reciprocating screw 22 to rotate. The reciprocating screw 22 then drives the lifting rod 21 to move upward, which in turn drives the mounting bracket 3 to move upward until it reaches the appropriate height.

[0049] To facilitate the installation of the blades on the arc-shaped block 35, the first motor 13 needs to be turned on. The output shaft of the first motor 13 drives the fixed rod 2 to rotate, which in turn drives the lifting rod 21 to rotate. The lifting rod 21 then drives the fixed frame 3 to rotate, which in turn drives the arc-shaped block 35 to rotate, thus lowering the height of the arc-shaped block 35 and making it easier to install the blades.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
