Description

Technical Field

[0001] This invention belongs to the technical field of belt conveyors, and specifically relates to an installation accessory for a suspended idler roller assembly. Background Technology

[0002] In the field of belt conveyor technology, idler rollers are used to support the weight of the conveyor belt and materials. Idler rollers are divided into two types of installation: fixed and suspended. Suspended idler rollers are suitable for working conditions where the working position of the belt conveyor changes frequently. They adapt to the deformation of the frame by changing the shape of the suspended idler rollers themselves. Therefore, suspended idler rollers are usually used in open-pit mine moving and semi-fixed belt conveyors.

[0003] Currently, the suspended idler roller assemblies used in domestic open-pit mines mainly follow the structural form of ThyssenKrupp. The three idler sections are hinged together by connecting plates. After hinge, the outermost idler roller assembly shaft is hinged to the hook (ring) by a connecting plate. The hooks (rings) on both sides are respectively hung (sleeved) on the mounting rings installed on the longitudinal beams of the intermediate frame of the belt conveyor. The mounting rings have a relatively complex shape and are usually made by casting. The mounting rings have elongated holes. One end of the elongated hole is fitted onto a fixed shaft welded to the longitudinal beam of the intermediate frame. A notch is machined around the fixed shaft to prevent the mounting ring from detaching from the fixed shaft. The other end of the elongated hole of the mounting ring is fitted onto an adjusting wrench. The adjusting wrench is a bent round bar with a small protrusion welded to the end of the bar, which presses against the mounting ring to fix it. When disassembling the idler roller assembly, the adjusting wrench is rotated so that the small protrusion is no longer pressing against the mounting ring, and the mounting ring can be removed for replacement of the idler roller assembly. The two semi-circular notches on the long hole of the mounting ring are used to fix the position of the hook (ring) to prevent it from moving around. At the same time, by inserting the hook (ring) into different notches, the forward tilt and normal installation position of the idler roller group can be adjusted. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a hanging idler assembly installation accessory. By using more common and cheaper materials and reducing the processing difficulty of the connecting parts between the hanging idler assembly and the longitudinal beam of the belt conveyor rollers, the processing cost of the hanging idler assembly installation accessory is reduced, the processing time is shortened, and thus the investment in the entire open-pit mine belt conveyor system is reduced.

[0005] The technical solution adopted in this invention is: a hanging idler roller assembly installation accessory, the key technical points of which include: The lifting components are installed at both ends of the suspended idler roller assembly; The idler roller fixing component serves as the load-bearing base for the entire installation accessory and is rotatably connected to the position adjustment plate; A position adjustment plate, which is rotatably connected to the roller fixing member and can be positioned at at least two angles, is used to support and adjust the suspension position of the hanging member; A positioning plate for detachably connecting to the lifting component; The lifting component passes through and connects the position adjustment plate and the roller fixing component; the connection between the positioning plate and the lifting component can lock the hanging roller assembly between the position adjustment plate and the roller fixing component, thereby completing the fixed installation.

[0006] In the above scheme, the idler fixing component has an elongated hole along the forward direction of the belt conveyor for the suspension component of the idler assembly to pass through. Two circular holes are symmetrically opened on the axis along the running direction of the belt conveyor.

[0007] In the above scheme, the position adjustment plate is provided with two short cylinders and one oblong hole along its length. The two short cylinders are inserted into the two holes and can drive the position adjustment plate to rotate and be lifted around the lifting component. The oblong hole is opened on the line connecting the centers of the two short cylinders. The major axis of the oblong hole is perpendicular to the line connecting the centers, and its center has a predetermined eccentricity relative to the midpoint of the line connecting the centers.

[0008] In the above scheme, the position adjustment plate rotates and repositions relative to the idler fixing component by changing the correspondence between the two short cylinders on it and the two circular holes on the idler fixing component; by rotating the position adjustment plate 180 degrees relative to the idler fixing component, the eccentric direction of the second elongated hole is switched, thereby realizing the adjustment of the suspended idler assembly between the normal working position and the forward tilting working position.

[0009] The above solution also includes a limiting component, which is fixed to the idler roller fixing component or the position adjustment plate. The side of the limiting component contacts the side of the positioning plate or leaves a small gap to limit the rotation of the positioning plate, thereby limiting the rotation of the hanging component at the end of the idler roller assembly.

[0010] The above solution also includes a limiting component, which is fixed on the positioning plate. The side of the limiting component contacts or leaves a small gap with the side of the position adjustment plate to limit the rotation of the positioning plate, thereby limiting the rotation of the hanging component at the end of the hanging roller group.

[0011] In the above scheme, the roller fixing component has an elongated hole along the axis of the length direction, and two short cylinders are symmetrically arranged in front of and behind the elongated hole.

[0012] In the above scheme, the position adjustment plate has two circular holes, the center distance between the two circular holes is the same as the center distance between the two short cylinders, and it can be detachably installed by being sleeved on the short cylinders; the second elongated hole is opened on the line connecting the centers of the two circular holes, the major axis of the second elongated hole is perpendicular to the line connecting the centers, and its center has a predetermined eccentricity relative to the midpoint of the line connecting the centers.

[0013] In the above scheme, the position adjustment plate rotates and repositions relative to the roller fixing component by changing the correspondence between its two circular holes and the two short cylinders on the roller fixing component; by rotating the position adjustment plate 180 degrees relative to the roller fixing component, the eccentric direction of the second elongated hole is switched, thereby realizing the adjustment of the suspended roller group between the normal working position and the forward tilting working position.

[0014] In the above scheme, the lifting component includes a round steel bar and a U-shaped ring. The round steel bar has a slot. The U-shaped ring is connected to the top of the round steel bar and can support the hanging roller assembly after the positioning plate is removed, so that it can be separated from the conveyor belt.

[0015] The beneficial effects of this invention are as follows: The hanging idler assembly installation accessory consists of a hanging component, an idler fixing component, a position adjustment plate, and a positioning plate. The hanging component simultaneously passes through and connects the position adjustment plate and the idler fixing component. The connection between the positioning plate and the hanging component locks the hanging idler assembly between the position adjustment plate and the idler fixing component, thus completing the fixed installation. This structure uses simple materials, all of which are common materials such as steel plates or round steel, making them easy to procure and inexpensive. The processing method is simple, requiring minimal processing; it can be manufactured through simple cutting, welding, and drilling operations, eliminating the need for casting processes. The processing method is simple, requiring minimal processing, and the processing speed is fast and the processing cost is low. It is also lightweight; while the main parts of the hanging idler assembly are the same as existing hanging idler assemblies, the weight of the hanging component and other accessories is lighter than existing hanging idler installation methods.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided in conjunction with the accompanying drawings. Figures 1-14 The present invention will be further described in detail below with reference to specific embodiments. Example 1:

[0020] This embodiment uses a hanging idler assembly installation accessory, including a hanging member 11 for the hanging idler assembly 1, a position adjustment plate 2, a positioning plate 3, and an idler fixing member 4. The hanging members 11 at both ends of the hanging idler assembly 1 pass sequentially through the elongated holes 41 of the idler fixing member 4 and the elongated holes 22 of the position adjustment plate 2 installed on the idler fixing member 4, and are then secured in the slots 113 of the hanging members 11 by the positioning plate 3, so that the hanging idler assembly is fixed on the installation accessory composed of the position adjustment plate 2, the positioning plate 3, and the idler fixing member 4.

[0021] In this embodiment, the idler roller fixing component 4 is fixedly installed on the frame of the belt conveyor (and can also serve as the longitudinal beam of the intermediate frame). An elongated hole 41 is opened on the idler roller fixing component 4 along the forward direction of the belt conveyor for the suspension member 11 of the idler roller assembly to pass through, and to provide space for adjusting the position of the suspension member 11 along the running direction of the belt conveyor. The inner width (circular diameter) of the elongated hole 41 is slightly larger than the diameter of the round steel 111 of the suspension member 11. Symmetrical circular holes 42 are opened on the axis of the elongated hole 41 along the running direction of the belt conveyor, located on both the front and rear sides of the elongated hole 41, for fixing the position adjustment plate 2.

[0022] Two short cylinders 21 are welded along the length of the position adjustment plate 2. The diameter of the short cylinders 21 is slightly smaller than that of the circular hole 42. The two short cylinders 21 can be separably inserted into the two circular holes 42 to achieve the positioning and installation of the position adjustment plate 2 on the idler roller fixing component 4. An elongated hole 22 is opened on the center line connecting the two short cylinders 21 on the position adjustment plate 2. The inner width (circular diameter) of the elongated hole 22 is slightly larger than the diameter of the round steel 111 of the hanging component 11. The short axis of the elongated hole 22 coincides with the center line connecting the two short cylinders 21, but the center of the elongated hole 22 does not coincide with the center of symmetry of the two short cylinders 21. The position of the elongated hole 22 (towards or backwards the center) can be adjusted by changing the correspondence between the short cylinders 21 and the circular hole 42, thereby achieving the adjustment of whether the idler roller tilts forward.

[0023] In this embodiment, the suspended idler roller assembly 1 is a three-section hinged idler roller assembly, with lifting components 11 connected to both ends via connecting plates, bolts, and nuts. The lifting component 11 consists of a round steel bar 111 and a U-shaped ring 112. The lower end of the round steel bar 111 is connected to the idler roller assembly. Two slots 113 are cut on the side wall of the round steel bar 111 near the upper end, similar to the mounting slots at both ends of the shaft of the fixed idler roller. During the installation of the suspended idler roller, these slots engage with the U-shaped groove on the positioning plate 3 to lock the suspended idler roller assembly in place, fixing it to the position adjustment plate 2 on the idler roller fixing component 4. The two straight segments of the U-shaped ring 112 are welded to both sides of the end of the round steel bar 111, forming a closed ring, which assists in the assembly and disassembly of the suspended idler roller.

[0024] During installation, the lifting parts 11 (specifically, the round steel parts 111) at both ends of the suspended roller assembly 1 are passed sequentially from bottom to top through the elongated holes 41 of the roller fixing part 4 and the elongated holes 22 of the position adjustment plate 2. Then, the positioning plate 3 is inserted horizontally, so that its U-shaped groove is engaged in the slot 113 of the lifting part 11. Since the width of the slot 113 matches the thickness of the positioning plate 3, and both ends of the positioning plate 3 are supported by the upper surface of the position adjustment plate 2, the lifting parts 11 are locked in place, preventing them from moving up and down, and finally the entire suspended roller assembly 1 is securely suspended.

[0025] Working principle and operating procedures: (1) Normal working state. For example... Figure 2As shown, after installation, the long axis (left-right direction) of the elongated hole 41 of the roller fixing component 4 is perpendicular to the long axis (up-down direction) of the elongated hole 22 of the position adjusting plate 2. The lifting component 11 is confined within the limiting space formed by these two mutually perpendicular elongated holes and the positioning plate 3, and can only swing slightly when subjected to a large external force to adapt to the deformation of the frame.

[0026] (2) Adjustment of the forward tilt working position. The position of the long hole 22 is adjusted by adjusting the corresponding relationship between the two short cylinders 21 of the position adjustment plate 2 and the circular hole 42 (to be slightly forward or slightly backward from the center, with an eccentricity of 5mm-25mm), thereby realizing the adjustment of whether the hanging roller group is tilted forward. The specific operation is as follows: Pull out the positioning plate 3 (optional step), drag the U-shaped ring 112 to slightly lift the hanging part 11, lift the position adjustment plate 2 so that the short cylinder 21 is disengaged from the round hole 42, keep the hanging part 11 in the second long hole 22, rotate the adjustment plate 2 around the hanging part 11 by 180°, then realign the short cylinder 21 with the round hole 42 and fit it in place, insert the positioning plate 3 back into the slot 113 of the hanging part 11 (optional step), release the drag force of the U-shaped ring 112 to return the hanging part 11 to its original position, and use the characteristic that the center of the second long hole 22 does not coincide with the symmetrical center of the two short cylinders 21 to realize the front and back adjustment of the position of one end of the hanging roller group, thereby realizing the adjustment of the normal working position and the forward tilting working position of the hanging roller group.

[0027] (3) Disengagement of the suspended idler assembly. When the suspended idler is damaged and cannot be repaired in time, the positioning plate 3 can be pulled out, allowing the suspended idler to descend naturally under gravity until the two ends of the U-shaped ring 112 abut against the upper surface of the position adjustment plate 2 or the idler fixing part 4. At this time, the suspended idler has descended a certain height and disengaged from the conveyor belt, avoiding affecting the normal operation of the belt conveyor. The idler can be replaced when the machine is stopped for maintenance.

[0028] (4) Replacement of the suspended idler assembly. When the idler assembly needs to be replaced, first drag the U-ring 112 to slightly lift the lifting part 11, pull out the positioning plate 3, and lift the position adjustment plate 2 so that the short cylinder 21 is disengaged from the round hole 42. At this time, rotate the adjustment plate 2 about 90° so that the long axis of the second long hole 22 of the adjustment plate 2 and the long axis of the long hole 41 of the idler fixing part 4 are aligned. Take the lifting part 11 (mainly the U-ring 112) out of the second long hole 22 and the long axis of the long hole 41 to realize the disassembly of the suspended idler assembly 1. The installation and replacement of the suspended idler assembly are exactly the reverse of the disassembly of the suspended idler assembly. Example 2:

[0029] The difference between this embodiment and embodiment 1 is that the structure of the idler fixing component 4 used in this embodiment is as follows: an elongated hole 41 is opened on the idler fixing component 4 along the forward direction of the belt conveyor, which is used to pass through the hanging component 11 of the idler assembly and to reserve enough space for the idler to tilt forward; short cylinders 142 are symmetrically welded to the front and back of the elongated hole 41 along the axis of the belt conveyor running direction.

[0030] The position adjustment plate 2 has two circular holes 121 along its length. The diameter of the circular holes 121 is slightly larger than that of the short cylinder 142. The center distance between the two circular holes 121 is the same as the center distance between the two short cylinders 142. The position adjustment plate 2 is installed on the roller fixing component 4 by the mutual mating of the circular holes 121 and the short cylinders 142. A second oblong hole 22 is made on the line connecting the centers of the two circular holes 21. The short axis of the second oblong hole 22 coincides with the line connecting the centers of the two circular holes 21, but the center of the second oblong hole 22 does not coincide with the center of symmetry of the two circular holes 121.

[0031] In this embodiment, the side of the short cylinder 142 contacts the side of the positioning plate 3 or leaves a small gap of 1mm to 2mm to restrict the rotation of the positioning plate 3, thereby restricting the rotation of the hanging member 11 at the end of the hanging roller group 1. Example 3:

[0032] The difference between this embodiment and embodiment 1 is that this embodiment also includes a limiting member 5. The limiting member 5 in this embodiment is a rectangular steel plate, which is welded to the upper surface of the roller fixing member 4 near the upper edge of the positioning plate 3 or to the upper surface of the position adjustment plate 2 near the upper edge (or both sides) of the positioning plate 3. Its side is in contact with the side of the positioning plate 3 or has a gap of 1mm to 2mm to limit the rotation of the positioning plate (3). Example 4:

[0033] The difference between this embodiment and embodiment 3 is that the limiting member 5 in this embodiment is a rectangular steel plate, which is fixed on the lower surface of the positioning plate 3 near the upper end of the positioning plate 3. The side of the limiting member 5 contacts the side of the position adjustment plate 2 or leaves a gap of 1mm to 2mm to restrict the rotation of the positioning plate 3, thereby restricting the rotation of the hanging member 11 at the end of the hanging roller group 1.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
