Description

Technical Field

[0001] This utility model relates to the field of material conveying and hoisting technology, specifically to a belt deviation measuring device for a bucket elevator. Background Technology

[0002] A belt bucket elevator is a vertical lifting device that uses a belt as the traction component. During its operation, the belt is prone to deviating to both sides due to factors such as initial installation accuracy, wear of the rubber surface of the head roller, and deformation of the bucket.

[0003] Existing technologies in bucket elevators employ a drum-shaped design for the head and tail pulleys to control belt misalignment. While this method has some effectiveness, when conveying highly adhesive or high-moisture materials, the material's influence often causes the belt on the head and tail pulleys to stick or slip, leading to misalignment. If misalignment is not detected and adjusted promptly, it can directly cause the belt to scrape against the elevator casing, damaging the equipment and posing safety hazards. Therefore, to avoid these problems, it is necessary to be able to detect belt misalignment faults in a timely manner. In light of this, we propose a belt misalignment detection device for bucket elevators. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned in the background art and provide a belt deviation measuring device for bucket elevators.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A belt misalignment measuring device for a bucket elevator is symmetrically installed on the elevator. A belt body is driven and installed inside the elevator, and multiple elevator buckets are mounted on the belt body.

[0007] The housing is detachably installed on the hoist and located on both sides of the conveyor belt body;

[0008] The limit and deviation measuring assembly includes two side swing arms mounted inside the housing via a central shaft. Rollers are rotatably mounted on the outer ends of the two side swing arms. The rollers are used to block the belt body when it deviates from its original direction.

[0009] A proximity switch is mounted on one end of the central shaft via a bracket and located outside the housing, used to issue a switching signal when the tape body deviates from its intended path;

[0010] The spring unit is mounted at both ends on the limiting and measuring assembly and the housing, respectively.

[0011] Preferably, the roller is rotatably mounted on a roller shaft via a bearing, and the roller shaft is mounted on the outer ends of the two side swing arms.

[0012] Preferably, a bushing for inserting the central shaft is installed on the inner side of the side swing arm, and a fixing screw is installed between the bushing and the central shaft.

[0013] Preferably, a connecting rod is connected to the bushing, and a tension spring is installed between the connecting rod and the housing as the spring unit.

[0014] Preferably, the deviation measuring device is installed on the hoist and located on both sides of the conveyor belt body in the descending section.

[0015] Preferably, each of the proximity switches is electrically connected to an indicator light, which is used to receive the switch signal and issue a deviation warning.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This belt deviation detection device for bucket elevators can activate when the belt deviates due to the presence of a limit-positioning component, triggering a proximity switch to issue a warning signal. It has a robust and reliable structure, is easy to assemble and disassemble, and is practical. It can effectively detect belt movement and make accurate judgments. Furthermore, the device can be reset after the deviation fault is cleared, facilitating continuous monitoring. Attached Figure Description

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Please see Figure 1-7 The present invention will describe the above technical solution in detail through the following embodiments:

[0030] A belt misalignment measuring device for a bucket elevator, such as Figure 6 and Figure 7 In this embodiment, two deviation measuring devices are installed on both sides of the conveyor belt body 13 located on the elevator and in the descending section. The main purpose of these devices is to ensure that when the conveyor belt body 13 deviates, it will come into contact with the deviation measuring devices on both sides.

[0031] The device includes a housing 1 detachably mounted on the hoist and located on both sides of the conveyor belt body 13, providing a mounting point; a limit-positioning and deviation-measuring assembly is installed inside the housing 1, such as... Figure 3-Figure 5 The structure shown includes two side swing arms 4 mounted inside the housing 1 via a central shaft 3. Rollers 2 are rotatably mounted on the outer ends of the two side swing arms 4. The rollers 2 are used to block the belt body 13 when it deviates. Specifically, the rollers 2 are rotatably mounted on a roller shaft 7 via a bearing 8. The roller shaft 7 is mounted on the outer ends of the two side swing arms 4 to keep the rollers 2 running smoothly.

[0032] A bushing 10 for inserting the central shaft 3 is installed on the inner side of the side swing arm 4. A fixing screw is installed between the bushing 10 and the central shaft 3 to maintain the synchronization of the overall rotation. To obtain a stable connection structure, in this embodiment, a connecting rod 11 is connected to the bushing 10, and a tension spring 5 is installed between the connecting rod 11 and the housing 1. Figure 7 As shown in the positional relationship, the tension spring 5 mainly maintains the upward preload of the front side swing arm 4. In this embodiment, it is installed in the descending section, and the offset conveyor belt body 13 will press down on the roller 2, causing the tension spring 5 to stretch. When the deviation fault is cleared, the tension spring 5 will... Figure 7The reset is complete, preparing for the next test.

[0033] To issue timely warnings, in this embodiment, the proximity switch 6 is mounted on one end of the central shaft 3 via the support 9 and located outside the housing 1. The proximity switch 6 is an existing mature product. When the distance changes, it triggers a switch signal. Since the structure rotates synchronously along the central shaft 3, the deviation of the tape body 13 will cause the proximity switch 6 to operate. Specifically, in this embodiment, the proximity switches 6 on both sides are electrically connected to indicator lights. When the tape body 13 deviates, the indicator lights issue a deviation warning. The indicator lights on both sides have their own independent power circuits. When either indicator light is "on", it indicates that the tape has deviated, and the deviation direction is towards the side where the corresponding proximity switch 6 is located.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0035] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
