Description

Technical Field

[0001] This invention relates to the field of idler roller technology, and more specifically, to an idler roller frame and a method for facilitating the assembly and disassembly of idlers. Background Technology

[0002] Idler rollers are an important component of belt conveyors, supporting the conveyor belt and the weight of the materials. Idler rollers must operate flexibly and reliably to reduce friction between the conveyor belt and the rollers, ensuring the lifespan of the conveyor belt. Idler rollers require idler frames for installation, but installation and replacement of idler rollers can be cumbersome.

[0003] In view of this, Chinese utility model patent CN210527595U discloses a roller frame structure that facilitates the installation and removal of idlers. The structure includes a first roller frame plate and a second roller frame plate mounted on a frame. The first and second roller frame plates are parallel and symmetrically arranged. Mounting grooves are provided on the inner end faces of both the first and second roller frame plates. Each mounting groove includes a first slot for placing an idler roller and a second slot communicating with the first slot. The second slot on the first roller frame plate penetrates through the bottom end of the first roller frame plate, and the second slot on the second roller frame plate penetrates through the bottom end of the second roller frame plate. The second slot allows the idler roller to enter the first slot from bottom to top, thereby fixing it to the first and second roller frame plates. This roller frame structure, which facilitates the installation and removal of idlers, has a novel overall structure. Idler rollers can be installed from bottom to top or removed from top to bottom, allowing for easy replacement of idlers without adjusting other components of the feeder. This makes maintenance more convenient, saving time and effort.

[0004] However, this idler frame structure is not suitable for installing idlers of different sizes. When the idler frame is subjected to force in the axial direction of the idler, there is a risk of the idler separating from the idler. In addition, multiple people are required to cooperate in the installation of the idler, which is troublesome and the installation efficiency of the idler is low. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, this invention proposes an idler frame that facilitates the installation and removal of idlers. This idler frame enables a single person to install and remove idlers, making operation convenient, ensuring the safety and stability of idler operation, and improving the installation efficiency of idlers.

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the idler frame for easy assembly and disassembly of the idler in this embodiment of the invention includes a base plate 1, two support plates 2, a top support plate 3, and fasteners 4. The two support plates 2 are both disposed on the base plate 1, and both support plates 2 are movable in a first direction so that the distance between the two support plates 2 is adjustable. The support plates 2 are provided with mounting holes 21 for the roller shaft at the end of the idler to pass through. The top support plate 3 is disposed above the base plate 1 in an adjustable position along the height direction. The top support plate 3 is used to support the idler. The fasteners 4 are disposed one-to-one with the mounting holes 21 and are rotatably assembled on the support plates 2. The fasteners 4 are used to clamp and fix the roller shaft.

[0043] In this embodiment of the invention, the idler frame facilitates the installation and removal of idlers. When installing an idler, the two support plates 2 are moved so that the distance between them is greater than the length of the idler to be installed. The idler to be installed is placed on the top support plate 3, and the top support plate 3 is moved to lift the idler to the desired installation height. The two support plates 2 are then moved so that the roller shafts at both ends of the idler pass through the mounting holes 21, and the roller shafts are clamped and fixed using fasteners 4. When removing an idler, the top support plate 3 is moved to the bottom of the idler to be removed, and the idler to be removed is lifted by the top support plate 3. The clamping of the roller shafts at both ends of the idler by the fasteners 4 is released, and the two support plates 2 are moved to separate the idler to be removed from the support plates 2.

[0044] The idler frame of this invention, which facilitates the installation and removal of idlers, enables a single person to install and remove idlers, making operation convenient, ensuring the safety and stability of idler operation, and improving the installation efficiency of idlers.

[0045] In some embodiments, such as Figure 1 As shown, it includes a drive rod 5, which is rotatably mounted on the base plate 1. The drive rod 5 passes through two support plates 2 and is threadedly connected to the two support plates 2. The drive rod 5 has two threaded sections with opposite threads and the same length. The two support plates 2 are respectively located on the two threaded sections. The drive rod 5 is used to drive the two support plates 2 to move simultaneously toward each other or away from each other.

[0046] The two support plates 2 are moved simultaneously by the drive rod 5, which is convenient to operate. The two support plates 2 can be moved simultaneously towards each other or away from each other by two threaded sections with opposite threads and the same length. This can increase the efficiency of the drive rod 5 in adjusting the distance between the two support plates 2 and improve the efficiency of disassembling and assembling the idler roller.

[0047] Optionally, the base plate 1 is provided with two guide grooves 11 along the first direction, and two support rods are slidably assembled in the two guide grooves 11. The drive rod 5 passes through the two guide grooves 11 along the first direction and is rotatably connected to the base plate 1.

[0048] In some embodiments, such as Figure 1 and Figure 2As shown, the device includes an adjustment assembly 6, which comprises two first rods 61, two second rods 62, two adjustment blocks 63, a first plate 64, a second plate 65, and an adjustment rod 66. The ends of the two first rods 61 that are close to each other are rotatably connected to the first plate 64, and the ends of the two first rods 61 that are far apart from each other are rotatably connected to the two adjustment blocks 63. The ends of the two second rods 62 that are close to each other are rotatably connected to the second plate 65, and the ends of the two second rods 62 that are far apart from each other are rotatably connected to the two adjustment blocks 63. The first plate 64 is located below the top support plate 3, and the second plate 65 is located on the bottom plate 1. The adjustment rod 66 passes through one of the adjustment blocks 63 and is threadedly connected to the adjustment block 63. The other end of the adjustment rod 66 is rotatably connected to the other adjustment block 63.

[0049] When the adjusting rod 66 is rotated, the two adjusting blocks 63 move closer to each other. Simultaneously, the two adjusting blocks 63, through the first rod 61 and the second rod 62, cause the first plate 64 and the second plate 65 to move further apart, thereby raising the height of the first plate 64 and the top support plate 3. Conversely, when the two adjusting blocks 63 move further apart, they simultaneously, through the first rod 61 and the second rod 62, cause the first plate 64 and the second plate 65 to move closer together, thereby lowering the height of the first plate 64 and the top support plate 3. The threaded connection between the adjusting rod 66 and one of the adjusting blocks 63 makes height adjustment of the top support plate 3 more convenient, broadens the applicability of the idler roller's installation height, and ensures the stability of the top support plate 3 during height adjustment, preventing relative rotation of the top support plate 3 and thus avoiding the idler roller slipping off.

[0050] In some embodiments, such as Figure 1 As shown, a groove 12 is provided on the base plate 1 along a second direction perpendicular to the first direction, and a third plate 7 is provided between the second plate 65 and the base plate 1. The third plate 7 is slidably assembled in the groove 12 and is adapted to the size of the groove 12.

[0051] The slide groove 12 and the third plate 7 are provided. By sliding the third plate 7 in the slide groove 12, the overall position of the adjustment component 6 can be adjusted, making it easier to place the roller on the top support plate 3.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the top support plate 3 is rotatably connected to the first plate 64.

[0053] When installing the idler roller, the extension direction of the top support plate 3 can be adjusted to facilitate the placement of the idler roller.

[0054] Optionally, rotational damping is provided between the top support plate 3 and the first plate 64.

[0055] In some embodiments, such as Figure 1 and Figure 2As shown, the second plate 65 is rotatably connected to the third plate 7.

[0056] When installing the idler roller, the entire adjusting assembly 6 can be rotated to facilitate the placement of the idler roller.

[0057] Optionally, rotational damping is provided between the second plate 65 and the third plate 7.

[0058] In some embodiments, such as Figure 1 and Figure 3 As shown, the fastener 4 includes a connecting plate 41, a first half-ring 42, and a second half-ring 43. The connecting plate 41 is rotatably connected to the support plate 2, and the connecting plate 41 has a through hole corresponding to the mounting hole 21. The first half-ring 42 is fixedly disposed on the connecting plate 41 corresponding to the through hole, and the second half-ring 43 is disposed on the connecting plate 41 in an adjustable position corresponding to the first half-ring 42. The first half-ring 42 and the second half-ring 43 are used to clamp and fasten the roller shaft.

[0059] The position of the second half-ring 43 is adjustable, which enables the clamping and fixing of the roller shaft and the release of the clamp. When the second half-ring 43 and the first half-ring 42 clamp and fix the roller shaft of the idler roller, the first half-ring 42 and the second half-ring 43 rotate with the roller shaft under the action of the connecting plate 41, which is safe and reliable.

[0060] Optionally, the ends of the first half-ring 42 and the second half-ring 43 are provided with lugs. Among the two lugs on the same side, the upper lug is threaded with a fastening bolt, and the end of the fastening bolt is rotatably connected to the lower lug.

[0061] In some embodiments, the second half-ring 43 is elastic, and the arc length corresponding to the second half-ring 43 is less than the arc length corresponding to the first half-ring 42.

[0062] The elastic deformation of the second half-ring 43 ensures the clamping effect on the roller shaft of the idler. The arc length corresponding to the second half-ring 43 is less than the arc length corresponding to the first half-ring 42, which makes the fastener 4 applicable to idler rollers whose roller shaft radius is smaller than the radius of the circle corresponding to the first ring, thus improving the applicability of the fastener 4.

[0063] In some embodiments, such as Figure 1 As shown, the connecting plate 41 is located on one side of the two support plates 2 that are opposite to each other. A bearing is provided between the connecting plate 41 and the support plate 2. The inner ring of the bearing is fixedly connected to the connecting plate 41, and the outer ring of the bearing is fixedly connected to the support plate 2.

[0064] The connecting plate 41 is located on the side opposite to the two support plates 2, which facilitates the adjustment of the fastener 4 to clamp and release the roller shaft of the idler. It also has a stop fit with the support plate 2 in the axial direction of the roller shaft, which ensures the stability of the idler during rotation operation and is safe and reliable.

[0065] In some embodiments, such as Figure 1 and Figure 2 As shown, the top support plate 3 is an arc-shaped plate, and a protective pad 31 is provided in the groove of the top support plate 3. The protective pad 31 has a double-layer cavity structure.

[0066] By setting the top support plate 3 as an arc plate, the contact area between the top support plate 3 and the idler roller to be installed is increased. A protective pad 31 is provided on the top support plate 3 to fill the gap between the top support plate 3 and the idler roller to be installed, preventing the idler roller from slipping. The protective pad 31 with a double-layer cavity structure can increase the deformation capacity of the protective pad 31, which can further increase the contact area between the protective pad 31 and the roller, ensuring the stability of the idler roller when placed on the top support plate 3.

[0067] Optionally, the protective pad 31 is a rubber pad and is elastic.

[0068] The following describes the method for disassembling and assembling idlers according to an embodiment of the present invention.

[0072] S2. Release the fastener 4 from clamping the roller shafts at both ends of the idler roller, and move the two support plates 2 to separate the idler roller to be disassembled from the support plates 2.

[0073] S3. Move the two support plates 2 so that the distance between the two support plates 2 is greater than the length of the roller to be installed;

[0074] S4. Place the idler roller to be installed on the top support plate 3, and move the top support plate 3 to the installation height of the idler roller to be installed.
