Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor testing technology, specifically relating to a belt conveyor dynamic testing frame. Background Technology

[0002] Belt conveyors, also known as belt conveyors, are important transportation equipment in the mining industry. The operating status of the equipment plays a decisive role in on-site production safety and efficiency. In order to ensure normal production, workshop personnel generally need to conduct regular inspections to detect and resolve problems early, thereby ensuring the reliability of the equipment during long-term operation.

[0003] Among them, belt misalignment is a common fault of belt conveyors during operation. Currently, employees usually rely on experience to make judgments during on-site inspections, as there are no fixed reference objects on site, which requires a high level of ability and experience from the employees.

[0004] To address this, we propose a belt dynamic detection frame for belt conveyors to reduce the difficulty of belt misalignment inspection and ensure reliable equipment operation and safe production. Utility Model Content

[0005] The purpose of this invention is to provide a dynamic detection frame for belt conveyor operation to solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dynamic monitoring frame for belt conveyor operation includes two uprights, a crossbeam installed between the tops of the two uprights, a centerline observation device installed in the middle of the crossbeam, and a belt offset reference unit installed between the middle of the two uprights. The two uprights are installed vertically on both sides of the belt conveyor, the crossbeam is horizontally positioned above the belt conveyor, and the installation position of the centerline observation device on the crossbeam corresponds vertically to the centerline position of the belt conveyor. The belt offset reference unit is horizontally positioned at the bottom of the belt conveyor.

[0008] Furthermore, the centerline observation device includes a housing mounted on a crossbeam. Observation windows are provided in the middle of both sides of the housing, and angle rulers are installed on both sides of the housing corresponding to the positions of the observation windows. A clearance hole is provided at the bottom of the housing along the length of the crossbeam. A plumb line is fixed inside the housing at the origin position of the two angle rulers via a rotating shaft. A line cone is installed at the bottom of the plumb line after it extends out of the housing through the clearance hole.

[0009] Furthermore, the angle ruler is a transparent plastic ruler, and the angle rulers on both sides of the outer shell are designed symmetrically with the central axis of the crossbeam as the center.

[0010] Furthermore, the housing also houses a power storage unit and an illumination lamp, and the cone has a laser emitter vertically mounted inside, with an aperture at the vertical tip for the laser beam to pass through. The power storage unit includes a battery pack and an electronic control module, which is electrically connected to the battery pack. The laser emitter and illumination lamp are electrically connected to the electronic control module, and the electronic control module has a switch mounted on it via wires.

[0011] Furthermore, the switch is mounted on the side of one of the stands.

[0012] Furthermore, the belt offset reference unit includes two sets of observation mechanisms. Each set of observation mechanisms includes a mounting sleeve that fits over the outside of the upright. An observation ruler is installed on one side of the mounting sleeve through a mounting post and a first fastening nut. The observation ruler has reference areas divided on both sides by engraving lines.

[0013] Furthermore, the ends of the observation scales in the two observation mechanisms that are furthest from the mounting sleeve are connected together by a spacer bushing and a second locking nut.

[0014] Furthermore, both ends of the observation scale are provided with elongated slots for engaging with the mounting post and the spacer sleeve. One end of the mounting post is fixed to the mounting sleeve, while the other end of the mounting post passes through the slot at the corresponding end of the observation scale and is then fitted with a first fastening nut to fix the observation scale to the mounting sleeve. A double-ended screw is inserted into the middle of the spacer sleeve, and both ends of the double-ended screw pass through the slots at the corresponding ends of the two observation scales and are then fitted with a second fastening nut to connect the two observation scales together.

[0015] Furthermore, the outer surface of the support frame is also provided with an adjustment ruler, and locking bolts are installed on the two mounting sleeves in the belt offset reference unit.

[0016] Beneficial effects:

[0017] This utility model has a simple overall structural design and is easy to install. During use, the entire inspection frame passes horizontally through the upper and lower spaces of the belt conveyor. Through the installed centerline observation device and belt offset reference unit, reference objects can be provided for the centerline of the belt during operation and the positions of both sides of the belt. This allows inspection personnel to more intuitively and accurately judge the current operating status of the belt conveyor through the reference objects, thereby relaxing the requirements for the work experience and ability of the relevant inspection personnel, and improving the accuracy of inspection judgment.

[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0024] Example:

[0025] Currently, during the inspection of belt conveyor operation, there is no effective reference to accurately determine the belt misalignment status. Inspectors can only estimate based on their own work experience and abilities, which places high demands on their skills and experience. Moreover, this estimation method can lead to significant deviations. To address this, we have designed a belt dynamic detection frame for belt conveyors as an inspection reference, thereby reducing the difficulty of belt misalignment inspection and ensuring reliable equipment operation and safe production.

[0026] like Figure 1As shown, this embodiment provides a dynamic detection frame for belt conveyor operation, including two uprights 1, a crossbeam 2 installed between the tops of the two uprights 1, and a centerline observation device 3 installed in the middle of the crossbeam 2; a belt offset reference unit 5 is installed between the middle of the two uprights 1; wherein, the two uprights 1 are installed vertically on both sides of the belt conveyor, while the crossbeam 2 is horizontally positioned above the belt conveyor. At the same time, the installation position of the centerline observation device 3 on the crossbeam 2 corresponds vertically to the centerline position of the belt of the belt conveyor, while the belt offset reference unit 5 is horizontally positioned at the bottom of the belt of the belt conveyor. The centerline observation device 3 serves as a reference for the centerline position of the belt from directly above the belt of the belt conveyor, and can also be used to measure the belt deflection angle. The main function of the belt offset reference unit 5 is to reflect the belt position in real time from both sides during the operation of the belt conveyor, so that the inspection personnel can more intuitively observe the belt operation status.

[0027] The entire device has a simple structure. During use, the centerline observation device 3 and the belt offset reference unit 5 installed on the detection frame provide references for the centerline position and side position of the belt conveyor, respectively. This allows inspection personnel to more intuitively and accurately judge the current operating status of the belt conveyor through the reference objects, thereby relaxing the work experience and ability requirements of relevant inspection personnel and improving the accuracy of inspection judgment.

[0028] To detect the belt centerline offset angle, such as Figure 3-4 As shown, the centerline observation device 3 specifically includes a housing 301 mounted on the crossbeam 2. Observation windows are provided in the middle of both sides of the housing 301, and angle gauges 302 are installed on both sides of the housing 301 corresponding to the positions of the observation windows. A clearance hole 304 is provided at the bottom of the housing 301 along the length of the crossbeam 2. A vertical line 305 is fixed inside the housing 301 at the origin of the two angle gauges 302 via a pivot 303. The bottom of the vertical line 305 extends out of the housing 301 through the clearance hole 304 and is then installed... The tapered cone 306 hangs naturally under the influence of gravity. During installation, it is only necessary to calibrate the position of the tapered cone 306 so that its tip is aligned with the center line of the belt. During use, the inspector can use the tapered cone 306 as a reference to clearly observe whether the position of the belt center line has shifted. When it is necessary to measure the offset angle, it is only necessary to manually pull the tapered cone 306 so that it overlaps with the belt center line again, and then read the value corresponding to the vertical line 305 on the angle ruler 302.

[0029] To improve the accuracy of belt centerline position detection, the angle gauge 302 is a transparent plastic gauge. The angle gauges 302 on both sides of the housing 301 are symmetrically designed with the central axis of the crossbeam 2 as the center. A power storage unit 307 and an illumination lamp 308 are also installed inside the housing 301. A laser emitter 309 is vertically installed inside the linear cone 306, with an aperture at the vertical tip of the linear cone 306 for the laser beam to pass through. The power storage unit 307 includes a battery pack and an electronic control module. The electronic control module is electrically connected to the battery pack, and the laser emitter 309 and illumination lamp 308 are electrically connected to the electronic control module. A switch 311 is installed on the side of one of the uprights 1 via a wire 310. It should be further noted that the electronic control module is a conventional control circuit found in current electronic products. Its main function is to cooperate with the switch 311 to control the opening and closing of the laser emitter 309 and illumination lamp 308. This is known technology and will not be described in detail here.

[0030] When using the centerline observation device 3, switch 311 is used to turn on the laser emitter 309 and the illumination bulb 308. The illumination bulb 308 illuminates the internal space of the housing 301, so that the operator can read the data corresponding to the vertical line 305 on the transparent angle ruler 302. The laser beam emitted by the laser emitter 309 in the cone 306 is emitted vertically from the hole under the cone 306 and displays the current position of the cone 306 on the belt of the conveyor belt. This is used to observe the position of the belt centerline. When it is necessary to measure the offset angle of the belt centerline, it is only necessary to manually swing the cone 306 (the cone 306 and the vertical line 305 need to be kept straight and in the same direction) so that the laser re-aligns with the belt centerline. At this time, the value on the angle ruler 302 can be read.

[0031] To more intuitively observe the operating status of the belt, such as Figure 2 As shown, its belt offset reference unit 5 includes two sets of observation mechanisms. Each set of observation mechanisms includes a mounting sleeve 501 that is sleeved on the outside of the upright frame 1. An observation ruler 503 is installed on one side of the mounting sleeve 501 through a mounting post 502 and a first fastening nut 505. The observation ruler 503 has reference areas divided on both sides by engraving lines 508. The end of the observation ruler 503 in the two observation mechanisms that is away from the mounting sleeve 501 is connected together through a spacer bushing 506 and a second locking nut to improve its stability. Its reference area can be divided into safe areas, low-risk areas and high-risk areas according to actual application requirements. The current operating status of the belt can be quickly determined by the area corresponding to the belt edge on the observation ruler 503.

[0032] Because the belt conveyors transport different materials with different specifications, the installation angles and slopes also vary. To improve the adaptability of the inspection frame, the observation ruler 503 needs to be designed to be flexible and adjustable. Specifically, both ends of the observation ruler 503 are provided with elongated slots 504 for engaging with the mounting post 502 and the spacer sleeve 506. One end of the mounting post 502 is fixed to the mounting sleeve 501, and the other end of the mounting post 502 passes through the slot 504 at the corresponding end of the observation ruler 503 and is then secured to the mounting sleeve 501 with a first fastening nut 505. A double-ended screw is inserted into the middle of the spacer sleeve 506. The two ends of the double-ended screw pass through the slots 504 at the corresponding ends of the two observation rulers 503 and are then secured to the two observation rulers 503 with a second fastening nut 507. An adjustment ruler 4 is also provided on the outer surface of the frame 1, and locking bolts 509 are installed on both mounting sleeves 501 in the belt offset reference unit 5.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
