Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a wear-resistant idler roller for belt conveyors. Background Technology

[0002] Belt conveyors are widely used in industries such as mining, coal, cement, and ports. During operation, the motor drives the drum to rotate, and the friction between the belt and the drum pulls the belt to move continuously, realizing the horizontal or inclined conveying of materials. As a key load-bearing component, the idler rollers bear the friction, impact and corrosion of the conveyor belt and materials for a long time, resulting in severe wear and shortened service life.

[0003] Traditional idlers are usually made of integral metal (such as carbon steel or stainless steel). This structure has the following problems: when the surface of the idler wears out, it often needs to be replaced as a whole, resulting in high maintenance costs. Therefore, designing a detachable, modular wear-resistant idler is of great practical significance. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a wear-resistant idler roller for belt conveyors to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides a wear-resistant idler roller for a belt conveyor, comprising:

[0006] Roller body;

[0007] Multiple high wear-resistant modules are detachably connected to each other to form a closed wear-resistant ring. The inner diameter of the wear-resistant ring is adapted to the outer diameter of the roller body so that the center lines of the two coincide after the wear-resistant ring is sleeved on the outer circumference of the roller body. The multiple wear-resistant rings are arranged sequentially along the axial direction of the roller body, and continuously cover the entire outer circumference of the roller body in a split structure to serve as a working surface to withstand the friction force of the conveyor belt.

[0008] A positioning structure is provided at both ends of the roller body to axially lock the wear-resistant ring, so as to prevent the wear-resistant ring from axially displacing relative to the roller body.

[0009] As a preferred embodiment of this utility model, the high wear-resistant module is an arc-shaped plate, one end of the high wear-resistant module has a locking block, and the other end of the high wear-resistant module has a locking groove that matches the locking block.

[0010] As a preferred embodiment of this utility model, the positioning structure includes:

[0011] Two end flanges, one end of which is formed with a connecting groove, and the roller body has connectors at both ends that are adapted to the connecting groove;

[0012] Multiple positioning rods are arranged in a circular array about the axis of the end flange. The positioning rods pass through a through groove on the surface of the end flange. The high wear-resistant module has a positioning groove that matches the positioning rod.

[0013] Threaded rods are provided at both ends of the positioning rod;

[0014] A nut, which is threadedly connected to the threaded rod.

[0015] As a preferred embodiment of this utility model, the positioning structure further includes an intermediate flange, which is fixedly disposed in the middle of the roller body, and one end of the positioning rod is fixed to the end face of the intermediate flange.

[0016] As a preferred technical solution of this utility model, the card block is preferably a T-shaped block, and correspondingly, the card slot is a T-shaped slot.

[0017] As a preferred embodiment of this utility model, the connector is a polygonal prism, and correspondingly, the connecting groove is a polygonal groove.

[0018] As a preferred technical solution of this utility model, the surface layer of the high wear-resistant module is made of wear-resistant ZTA ceramic, and the bottom layer is made of impact-resistant UHMW-PE, thus taking into account both wear resistance and toughness.

[0019] As a preferred embodiment of this utility model, the idler roller further includes:

[0020] The spindle has limit grooves at both ends;

[0021] Two bearing housings are disposed opposite each other at both ends of the roller body. The spindle passes through one of the bearing housings into the inner cavity of the roller body and exits from the other bearing housing.

[0022] A ball bearing, which is disposed in the bearing housing and sleeved on the outer circumferential surfaces of both ends of the spindle;

[0023] The end cap, which is threaded into the internal thread groove of the bearing housing, is used to axially fix the mandrel.

[0024] The beneficial effects of this utility model are as follows: This utility model combines and connects multiple high wear-resistant modules to form a wear-resistant ring, then sleeves the wear-resistant ring on the outer circumferential surface of the roller body, and uses a positioning structure to axially position the wear-resistant ring on the outer circumferential surface of the roller body. Multiple wear-resistant rings arranged axially in sequence can continuously cover the entire outer circumferential surface of the roller body, serving as a working surface to bear the friction force of the conveyor belt. When a wear-resistant ring wears out, only the corresponding wear-resistant ring needs to be replaced. Moreover, the wear-resistant ring itself is also composed of multiple high wear-resistant modules. Therefore, when the wear-resistant ring is partially worn, only the corresponding high wear-resistant modules need to be replaced to extend the service life of the wear-resistant ring.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0033] like Figure 1As shown, a wear-resistant idler roller for a belt conveyor includes: a roller body 1; multiple high wear-resistant modules 9, which are detachably connected end to end to form a closed wear-resistant ring. The inner diameter of the wear-resistant ring is adapted to the outer diameter of the roller body 1 so that the axis of the two coincides after the wear-resistant ring is sleeved on the outer circumferential surface of the roller body 1. The multiple wear-resistant rings are arranged sequentially along the axial direction of the roller body 1, and continuously cover the entire outer circumferential surface of the roller body 1 in a split structure to serve as a working surface to withstand the friction of the conveyor belt; and a positioning structure located at both ends of the roller body 1 to axially lock the wear-resistant rings to prevent the wear-resistant rings from axially displacing relative to the roller body 1.

[0034] The above technical solution extends the service life of the idler roller by replacing the worn parts. In use, multiple high-wear-resistant modules 9 are interconnected to form a wear-resistant ring, which is then fitted onto the outer circumference of the roller body 1. A positioning structure is used to axially position the wear-resistant ring on the outer circumference of the roller body 1, preventing axial movement of the idler roller during operation. Multiple axially arranged wear-resistant rings continuously cover the entire outer circumference of the roller body 1, serving as the working surface to withstand the friction of the conveyor belt. When a wear-resistant ring wears out, only the corresponding wear-resistant ring needs to be replaced. Since the wear-resistant ring itself is composed of multiple high-wear-resistant modules 9, when a wear-resistant ring is partially worn, only the corresponding high-wear-resistant modules 9 need to be replaced to extend the service life of the wear-resistant ring. The purpose of aligning the centerlines of the wear-resistant ring and the roller body 1 is to prevent eccentric force when the idler roller rotates, reducing vibration and improving the conveying stability of the belt conveyor.

[0035] like Figure 4 As shown, in this embodiment, the high wear-resistant module 9 is an arc-shaped plate, one end of the high wear-resistant module 9 is formed with a locking block 11, and the other end of the high wear-resistant module 9 is formed with a locking groove 12 that matches the locking block 11; preferably, the locking block 11 is a T-shaped block, and correspondingly, the locking groove 12 is a T-shaped groove.

[0036] The above technical solution can connect multiple high wear-resistant modules 9 end to end to form a wear-resistant ring. In use, the locking block 11 of one high wear-resistant module 9 is inserted into the locking slot 12 of another high wear-resistant module 9 to assemble two adjacent high wear-resistant modules 9 together. Following this operation method, multiple high wear-resistant modules 9 can be assembled into a ring-shaped wear-resistant ring. In order to prevent gaps between adjacent high wear-resistant modules 9, a sealing strip can be set between the high wear-resistant modules 9 to adapt to working scenarios with a lot of dust.

[0037] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the positioning structure includes: two end flanges 13, one end of which has a connecting groove 17, and the roller body 1 has connectors 18 at both ends that are adapted to the connecting groove 17. The connectors 18 are polygonal prisms, and correspondingly, the connecting groove 17 is a polygonal groove; multiple positioning rods 8 are arranged in a circular array about the axis of the end flanges 13, and the positioning rods 8 pass through the through grooves 14 opened on the surface of the end flanges 13. The high wear-resistant module 9 has positioning grooves 10 adapted to the positioning rods 8; threaded rods 15 are provided at both ends of the positioning rods 8; and nuts 16 are threadedly connected to the threaded rods 15.

[0038] The above technical solution allows for axial fixing of the wear-resistant rings from both ends of the roller body 1. During installation, first, align the connecting groove 17 of one end flange 13 with the connector 18 at one end of the roller body 1 and insert it. Then, insert all the positioning rods 8 into the through grooves 14 of the end flange 13, making the threaded rods 15 protrude from the end face of the end flange 13. Install the nuts 16 onto the threaded rods 15. Then, align the positioning grooves 10 of each assembled wear-resistant ring with the positioning rods 8 and insert them, thereby fitting the wear-resistant rings onto the outer surface of the roller body 1. Finally, align the connecting groove 17 of the other end flange 13 with the connector 18 at the other end of the roller body 1 and insert it. At the same time, the through groove 14 of the end flange 13 passes through the positioning rods 8, making the threaded rods 15 at one end of the positioning rods 8 protrude from the end face of the end flange 13. Install the nuts 16 onto the threaded rods 15 to complete the installation.

[0039] like Figure 2 As shown, in this embodiment, the positioning structure also includes an intermediate flange 7, which is fixedly disposed in the middle of the roller body 1, and one end of the positioning rod 8 is fixed to the end face of the intermediate flange 7.

[0040] The above technical solution can improve the efficiency of installation and disassembly. Since the positioning rod 8 has been fixed on the roller body 1 through the intermediate flange 7, during installation, the positioning groove 10 of the assembled wear-resistant ring can be directly aligned with the positioning rod 8 and inserted, without the need to install the positioning rod 8 separately.

[0041] Furthermore, in this embodiment, the surface layer of the high wear-resistant module 9 is made of wear-resistant ZTA ceramic, and the bottom layer is made of impact-resistant UHMW-PE.

[0042] The above technical solution enables the wear-resistant ring to combine wear resistance and toughness.

[0043] like Figure 2As shown, in this embodiment, the idler roller further includes: a spindle 5 with limiting grooves 6 at both ends; two bearing seats 2, which are disposed opposite to each other at both ends of the roller body 1, the spindle 5 passing through one of the bearing seats 2 into the inner cavity of the roller body 1 and exiting through the other bearing seat 2; ball bearings 3, which are disposed on the bearing seats 2 and sleeved on the outer circumferential surfaces at both ends of the spindle 5; and end caps 4, which are threadedly connected to the internal thread grooves of the bearing seats 2 for axially fixing the spindle 5.

[0044] The above technical solution can ensure that both ends of the mandrel 5 can be installed in the positioning groove of the bracket. At the same time, the mandrel 5 and the roller body 1 are connected by ball bearings 3, which can reduce the frictional resistance during rotation and reduce wear.

[0045] Working principle: When in use, insert the card block 11 of one high wear-resistant module 9 into the card slot 12 of another high wear-resistant module 9 to assemble two adjacent high wear-resistant modules 9 together. Following this operation method, multiple high wear-resistant modules 9 can be assembled into a ring-shaped wear-resistant ring.

[0046] Align the positioning groove 10 of each assembled wear ring with the positioning rods 8 on both sides of the middle flange 7 and insert them to fit the wear ring onto the outer surface of the roller body 1 until the wear rings are installed on both sides of the middle flange 7.

[0047] Finally, align the connecting grooves 17 of the two end flanges 13 with the connectors 18 at both ends of the roller body 1 and insert them so that the threaded rod 15 at one end of the positioning rod 8 protrudes from the end face of the end flange 13. At the same time, the through groove 14 of the end flange 13 passes through the positioning rod 8, so that the threaded rod 15 at one end of the positioning rod 8 protrudes from the end face of the end flange 13. Use the nut 16 to install it onto the threaded rod 15, thereby completing the installation.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
