Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically an assembled idler frame for belt conveyors. Background Technology

[0002] Belt conveyors, also known as conveyor belt systems, are mechanical devices that continuously transport materials using friction. These devices are favored by many industries due to their high efficiency, stability, and wide applicability, playing a crucial role, especially in mining, port handling, power generation, and chemical manufacturing. For example, CN217200412U discloses a belt conveyor idler roller, comprising: an idler roller section; and a fixed plate, wherein the middle part of the idler roller section is rotatably connected to the fixed plate via a rotating shaft.

[0003] Idler rollers are crucial components installed beneath the conveyor belt via idler frames. During prolonged operation and use, they often experience varying degrees of wear due to various factors. This wear is typically uneven, leading to eccentric wear. Uneven wear not only affects the service life of the idler rollers but can also negatively impact the normal operation of the conveyor belt. Therefore, to effectively prevent and avoid uneven wear, users and maintenance personnel need to conduct regular, thorough inspections of the idler rollers. However, because the idler rollers are located beneath the conveyor belt and are obstructed by the belt itself, it is difficult for inspectors to directly determine the presence of uneven wear through visual inspection. Utility Model Content

[0004] The purpose of this invention is to provide an assembled idler frame for belt conveyors to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembled idler frame for a belt conveyor, comprising a base, a roller frame body welded onto the base, a belt roller on the roller frame body, an installation opening on the roller frame body, a detection mechanism installed in the installation opening, the detection mechanism comprising a detection rod disposed in the installation opening, a movable groove on the detection rod, a return spring disposed in the movable groove, a detection probe disposed above the return spring, and a limiting mechanism disposed on one side of the detection probe.

[0006] Preferably, the movable slide is provided with a threaded interface, a sealing plug is provided at the threaded interface, and the sealing plug is provided with a movable hole.

[0007] Preferably, the detection probe is mounted on the detection rod at intervals via a movable sliding groove, and the detection rods are aligned with each other.

[0008] Preferably, the detection rod is connected to the roller frame body through the mounting port, and the detection rod is parallel to the belt roller. The detection rod passes through the sealing plug through the movable hole. One end of the return spring is connected to the bottom of the movable slide groove, and the other end of the return spring is connected to the bottom of the detection probe. The sealing plug is installed at the upper end of the movable slide groove through the threaded interface, and the return spring is restricted within the movable slide groove by the sealing plug.

[0009] Preferably, the limiting mechanism includes an installation sleeve fixedly installed inside the detection rod, a limiting support column slidably installed inside the installation sleeve, a beveled groove welded to one end of the limiting support column, a wedge block slidably installed on one side, a threaded seat welded to the wedge block, a threaded rod connected to the threaded seat, and a handwheel welded to one end of the threaded rod.

[0010] Preferably, the detection rod has a groove inside, and the wedge block is slidably installed inside the detection rod through the groove.

[0011] Preferably, the threaded seat has a threaded hole, the threaded rod is connected to the threaded seat through the threaded hole, the limiting support is slidably installed on one side of the detection probe through the mounting sleeve, and the wedge block is movably installed on one side of the inclined groove through the threaded seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, after the detection probe is aligned with the belt roller, the wedge block is moved backward by rotating the threaded rod, thereby releasing the restriction on the detection probe. Subsequently, the return spring drives the detection probe forward until it contacts the surface of the belt roller. When uneven wear occurs on the belt roller, the detection probe at the corresponding position will protrude further. By observing the consistency of the protruding length of the detection probe, the user can quickly determine whether uneven wear exists on the belt roller.

[0014] 2. In this application, after the detection probe contacts the surface of the belt roller, the wedge block is driven forward by rotating the threaded rod. During its forward movement, the wedge block pushes the limiting support on one side forward until it contacts the surface of the detection probe. This contact action restricts the reset of the detection probe, ensuring the constant extension length of the detection probe and facilitating the user to remove the detection rod and observe the probe's extension status.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an assembled idler frame for belt conveyors, including a base 1, a roller frame body 3 welded and installed on the base 1, a belt roller 4 provided on the roller frame body 3, an installation port 2 opened on the roller frame body 3, a detection mechanism 5 installed in the installation port 2, and a limiting mechanism 6 provided on one side of the detection probe 502. Through the cooperation of the detection mechanism 5 and the limiting mechanism 6, users can easily and quickly determine whether the belt roller 4 is worn unevenly.

[0022] like Figure 2 and Figure 3 As shown, the detection mechanism 5 includes a detection rod 501 disposed in the mounting port 2. The detection rod 501 is provided with a movable slide groove 507. A return spring 506 is disposed in the movable slide groove 507. A detection probe 502 is disposed above the return spring 506. A threaded interface 505 is provided on the movable slide groove 507. A sealing plug 503 is provided at the threaded interface 505. A movable hole 504 is provided on the sealing plug 503. The detection probe 502 is installed on the detection rod 501 at intervals through the movable slide groove 507, and the detection rods 501 are aligned with each other. The detection rod 501 is connected to the roller frame body 3 through the mounting port 2, and the detection rod 501 is parallel to the belt roller 4. The detection rod 501 passes through the sealing plug 503 through the movable hole 504. One end of the return spring 506 is connected to the bottom of the movable slide groove 507, and the other end of the return spring 506 is connected to the bottom of the detection probe 502.

[0023] Specifically, when the detection probe 502 is facing the belt roller 4, the operator can control the wedge block 606 to move backward by rotating the threaded rod 604. This action removes the obstruction from the detection probe 502, allowing the return spring 506 to function and push the detection probe 502 forward. During this movement, the detection probe 502 will contact the surface of the belt roller 4. If the belt roller 4 is experiencing uneven wear, the detection probe 502 will extend a longer distance at the location of the uneven wear to cover a larger area of ​​wear. The user can quickly determine whether the belt roller 4 has experienced uneven wear by observing whether the extension length of the detection probe 502 is uniform.

[0024] like Figure 2 and Figure 4 As shown, the limiting mechanism 6 includes an installation sleeve 602 fixedly installed inside the detection rod 501. A limiting support column 601 is slidably installed inside the installation sleeve 602. One end of the limiting support column 601 is welded and fixed with an inclined groove 603, and a wedge block 606 is slidably installed on one side. A threaded seat 605 is welded and fixed on the wedge block 606. A threaded rod 604 is connected to the threaded seat 605. A handwheel 607 is welded and fixed to one end of the threaded rod 604. A sliding groove is opened inside the detection rod 501, and the wedge block 606 is slidably installed inside the detection rod 501 through the sliding groove. A threaded hole is opened in the threaded seat 605, and the threaded rod 604 is connected to the threaded seat 605 through the threaded hole.

[0025] Specifically, after the detection probe 502 contacts the surface of the belt roller 4, the wedge block 606 can be controlled to move forward by rotating the threaded rod 604. During the forward movement of the wedge block 606, it applies force to push the limiting support 601 on one side forward as well. After moving forward, the limiting support 601 contacts the surface of the detection probe 502, thereby restricting the reset action of the detection probe 502. This mechanism ensures that the extended length of the detection probe 502 remains constant, allowing the user to easily remove the detection rod 501 and observe and check the extension status of the detection probe 502.

[0026] Working principle: When in use, insert the detection rod 501 into the mounting port 2, keeping the detection rod 501 parallel to the belt roller 4. Then rotate the detection rod 501 so that the detection probe 502 faces the belt roller 4. After the detection probe 502 faces the belt roller 4, the threaded rod 604 can be rotated to control the wedge block 606 to move backward, so that the detection probe 502 is no longer obstructed. After the detection probe 502 is no longer obstructed, the return spring 506 will push the detection probe 502 forward and abut against the surface of the belt roller 4. When the belt roller 4 is worn unevenly, the detection probe 502 at the unevenly worn position will extend further. The user can quickly determine whether the belt roller 4 is worn unevenly by observing whether the extension length of the detection probe 502 is consistent. After the detection probe 502 contacts the surface of the belt roller 4, the threaded rod 604 can be rotated to control the wedge block 606 to move forward. During the forward movement of the wedge block 606, it will push the limiting support 601 on one side to move forward. After the limiting support 601 moves forward, it will contact the surface of the detection probe 502, restricting the detection probe 502 to reset, so that the extension length of the detection probe 502 remains unchanged, making it convenient for the user to remove the detection rod 501 to observe the extension of the detection probe 502.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
