Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyors, and in particular to a device for monitoring the parallelism of belt conveyor rollers. Background Technology

[0002] As an important piece of equipment for material transportation in modern industry, the stability and efficiency of belt conveyors are crucial to the production process. Ensuring the parallelism between the rollers during the operation of a belt conveyor is one of the key factors in maintaining normal equipment operation, extending its service life, and ensuring safety.

[0003] Specifically, in existing technological applications, using laser rangefinders to monitor the parallelism of belt conveyor rollers has become a common practice. This approach requires fixing a laser rangefinder at both ends of each roller to be monitored, and determining whether the roller maintains an ideal parallel state by measuring the distance difference between the two ends. However, since these two laser rangefinders are installed separately, this means that the same installation steps must be repeated twice for each parallelism test, which not only increases the complexity and time cost of the work, but also increases the risk of inaccurate measurement results due to installation errors. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a belt conveyor roller parallelism monitoring device, which integrates two laser rangefinders through a telescopic assembly. During installation, only one end needs to be installed, eliminating the need for secondary installation and improving ease of use.

[0005] The present invention relates to a belt conveyor roller parallelism monitoring device, which includes two rangefinders; one of the rangefinders is fixed on the belt conveyor, and also includes a telescopic component and a locking mechanism.

[0006] The two rangefinders are connected by a telescopic assembly;

[0007] The locking mechanism is used to lock the state of the telescopic component.

[0008] As a preferred embodiment of this utility model, there are at least two telescopic components, at least one of which moves in the horizontal direction and at least one of which moves in the vertical direction.

[0009] The telescopic assembly includes two swing arms, one end of which is rotatably connected to form a V-shaped structure;

[0010] The other ends of the two swing arms are respectively connected to two rangefinders via rotating shafts.

[0011] As a preferred embodiment of this utility model, there are two telescopic components that move in the vertical direction.

[0012] As a preferred embodiment of this utility model, the locking mechanism is disposed on one of the rangefinders;

[0013] Locking mechanisms include:

[0014] There are two gears, each fixed to a vertically rotating shaft.

[0015] There are two toothed pins that are elastically and slidably mounted on the rangefinder; when the two rangefinders are in a fixed relative position, the toothed pins mesh with the gear.

[0016] The locking mechanism also includes:

[0017] The drive mechanism is used to drive the two toothed pins to slide synchronously.

[0018] As a preferred embodiment of this utility model, the driving mechanism includes:

[0019] A connecting block is fixedly connected to a toothed pin, and the connecting block has an oblique hole;

[0020] The sliding plate is slidably mounted on the rangefinder, and both ends of the sliding plate are fixed with drive shafts that pass through oblique holes.

[0021] As a preferred embodiment of the present invention, the connecting block is also provided with a straight hole, one end of which is connected to one end of the oblique hole;

[0022] The rangefinder is equipped with an elastic element to keep the drive shaft in a straight hole.

[0023] As a preferred embodiment of this utility model, the driving mechanism also includes a handle disposed on the sliding plate.

[0024] As a preferred embodiment of this utility model, the locking mechanism is installed on the rangefinder that is fixedly connected to the belt conveyor.

[0025] Compared with existing technologies, the advantages of this utility model are as follows: A rangefinder fixed to the belt conveyor is installed in place. Then, based on the length of the roller to be monitored, another rangefinder is moved to a suitable position by adjusting the telescopic assembly. When the two rangefinders are aligned with the two ends of the roller, a locking mechanism is used to fix the telescopic assembly. During measurement, the two rangefinders work simultaneously. Each rangefinder contains a laser emitter and a receiver. The laser emitter emits a laser beam onto the roller surface, and the receiver receives the reflected light. When the parallelism of the roller deviates, the reflection position of the laser beam on the roller surface changes, and the position of the light signal received by the receiver also changes accordingly. By calculating the deviation of the light signal position, the change in roller parallelism can be determined. Compared with the traditional method of installing laser rangefinders separately at both ends of each roller, this solution only requires one rangefinder fixedly installed on the belt conveyor, greatly reducing installation steps and lowering the complexity and time cost of the work. Simultaneously, by reducing one installation operation, the risk of inaccurate measurement results due to installation errors is reduced. Furthermore, the adjustable nature of the telescopic assembly can adapt to rollers of different lengths, improving the versatility of the device. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Example

[0036] Reference Figure 1 This embodiment provides a belt conveyor roller parallelism monitoring device, including two rangefinders 1; one of the rangefinders 1 is fixed on the belt conveyor, and the fixing method can be by welding or bolt fastening; it also includes a telescopic component 2 and a locking mechanism 3;

[0037] Two rangefinders 1 are connected by a telescopic assembly 2;

[0038] Locking mechanism 3 is used to lock the state of telescopic component 2;

[0039] The specific process of this device is as follows: A rangefinder 1, fixed to the belt conveyor, is installed in place. Then, based on the length of the roller to be monitored, the telescopic assembly 2 is adjusted to move another rangefinder 1 to a suitable position. When the two rangefinders 1 are aligned with the two ends of the roller, the telescopic assembly 2 is fixed using the locking mechanism 3. During measurement, both rangefinders 1 work simultaneously. A laser emitter and receiver are installed inside each rangefinder 1. The laser emitter emits a laser beam onto the roller surface, and the receiver receives the reflected light. When the parallelism of the roller deviates, the reflection position of the laser beam on the roller surface changes, and the position of the light signal received by the receiver also changes accordingly. By calculating the deviation in the position of the light signal, the change in the parallelism of the roller can be determined. Compared with the traditional method of installing a laser rangefinder 1 separately at each end of each roller, this solution only requires fixing one rangefinder 1 on the belt conveyor, greatly reducing installation steps and lowering the complexity and time cost of the work. Simultaneously, by reducing one installation operation, the risk of inaccurate measurement results due to installation errors is reduced. Furthermore, the adjustable nature of the telescopic assembly 2 allows it to adapt to rollers of different lengths, improving the versatility of the device.

[0040] As a preferred embodiment of this utility model, refer to Figure 1There are at least two telescopic components 2, at least one telescopic component 2 moves in the horizontal direction and at least one telescopic component 2 moves in the vertical direction. It should be noted that when installing telescopic components 2 that move in different directions, attention should be paid to the operating area to prevent collision.

[0041] The telescopic assembly 2 includes two swing arms 21, one end of which is rotatably connected to form a V-shaped structure;

[0042] The other ends of the two swing arms 21 are rotatably connected to the two rangefinders 1 via rotating shafts 22;

[0043] The specific process of telescopic component 2 is as follows: Figure 1 As shown, since one end of the two swing arms 21 is rotatably connected to form a V-shaped structure, and at least one telescopic component 2 moves in the horizontal direction and at least one telescopic component 2 moves in the vertical direction, the rangefinder 1 can translate. During the translation of the rangefinder 1, the angle of the V-shaped structure formed by the two swing arms 21 changes. The telescopic component 2 with the above structure has a large extension range and occupies little space.

[0044] As a preferred embodiment of this utility model, refer to Figure 1 There are two telescopic components 2 that move in the vertical direction. The two telescopic components 2 are symmetrically arranged. The two vertical telescopic components 2 can provide more stable support for the rangefinder 1. Compared with a single vertical telescopic component 2, it can better resist external interference during the adjustment process and prevent the rangefinder 1 from shaking or tilting, thereby improving the stability and accuracy of the measurement.

[0045] As a preferred embodiment of this utility model, refer to Figures 2-5 The locking mechanism 3 is installed on one of the rangefinders 1;

[0046] Locking mechanism 3 includes:

[0047] There are two gears 31, which are fixed on two rotating shafts 22 that move in the vertical direction. When the distance between the two rangefinders 1 changes, the swing arm 21 and the gears 31 rotate around the axis of the rotating shaft 22.

[0048] Two toothed pins 32 are elastically slidably mounted on the rangefinder 1. More specifically, the toothed pins 32 slide on the fixing block 33 which is fixedly connected to the rangefinder 1. A fixing ring 34 is fixed on the toothed pins 32, and a spring 35 is fitted on the toothed pins 32. The two ends of the spring 35 are in close contact with the fixing block 33 and the fixing ring 34, respectively. When the two rangefinders 1 are fixed in relative positions, the toothed pins 32 mesh with the gear 31 under the elastic force of the spring 35.

[0049] Locking mechanism 3 also includes:

[0050] The drive mechanism is used to drive the two toothed pins 32 to slide synchronously.

[0051] The specific working process of the locking mechanism 3 is as follows: When it is necessary to adjust the distance between the two rangefinders 1, the driving mechanism is operated to make the two toothed pins 32 overcome the elastic force of the spring 35 and disengage from the tooth groove of the gear 31. At this time, the angle of the swing arm 21 of the telescopic component 2 can be freely adjusted. As the angle of the swing arm 21 changes, the rotating shaft 22 drives the gear 31 to rotate. When the appropriate position is adjusted, the driving mechanism is released. Under the action of the spring 35, the toothed pins 32 re-engage with the gear 31, thereby locking the relative position of the two rangefinders 1. The meshing method of the gear 31 and the toothed pins 32 can provide a more accurate locking position and ensure that the rangefinders 1 will not be displaced during the measurement process.

[0052] As a preferred embodiment of this utility model, refer to Figures 2-5 The driving organizations include:

[0053] The connecting block 36 is fixedly connected to the toothed pin 32. The connecting block 36 has an oblique hole 37. The connecting block 36 is made of metal and is connected to the toothed pin 32 by welding or bolting.

[0054] The sliding plate 38 is slidably mounted on the rangefinder 1. Both ends of the sliding plate 38 are fixed with a drive shaft 310 passing through the inclined hole 37. More specifically, the sliding plate 38 slides vertically on the track 39 on the rangefinder 1, and the bottom end of the inclined hole 37 is inclined towards the rangefinder 1.

[0055] The specific working process of the drive mechanism is as follows: When it is necessary to adjust the distance between the two rangefinders 1, the sliding plate 38 is pushed to slide on the track 39. Since the drive shaft 310 is fixed on the sliding plate 38 and the drive shaft 310 is inserted into the inclined hole 37 of the connecting block 36, as the sliding plate 38 slides, the drive shaft 310 moves in the inclined hole 37. Because there is an angle between the movement trajectory of the drive shaft 310 and the inclined hole 37, the connecting block 36 and the toothed pin 32 are driven to move along the fixed block 33, thereby disengaging the toothed pin 32 from the gear 31. After the position of the rangefinder 1 is adjusted, the sliding plate 38 is released, and the toothed pin 32 re-engages with the gear 31 under the action of the spring 35.

[0056] As a preferred embodiment of this utility model, refer to Figures 2-5 The connecting block 36 also has a straight hole 311, one end of which is connected to one end of the oblique hole 37, such as... Figure 5 As shown, when the toothed pin 32 meshes with the gear 31, the sliding trajectory of the straight hole 311 coincides with that of the drive shaft 310. At this time, the up and down movement of the drive shaft 310 will not change the position of the toothed pin 32.

[0057] The rangefinder 1 is provided with an elastic element 312 for positioning the drive shaft 310 in the straight hole 311. The elastic element 312 can be a spring or a sheet, etc., and its function is to position the drive shaft 310 in the straight hole 311 through the elastic force of the elastic element 312.

[0058] When the sliding plate 38 is shaking, if the driving shaft 310 is in the straight hole 311, even if the sliding plate 38 moves, the driving shaft 310 will only move within the straight hole 311 and will not affect the position of the toothed pin 32. Only when the driving shaft 310 enters the inclined hole 37 from the straight hole 311 will it drive the toothed pin 32 to move. After the adjustment is completed, the driving shaft 310 returns to the straight hole 311 under the action of the elastic element 312, ensuring that the toothed pin 32 and the gear 31 are stably meshed.

[0059] As a preferred embodiment of this utility model, refer to Figure 5 The driving mechanism also includes a handle set on the sliding plate 38. The handle has an ergonomic shape and a non-slip texture on the surface, making it easy for operators to hold. Compared with directly pushing the sliding plate 38, holding the handle is more comfortable and less strenuous, improving the convenience of operation.

[0060] As a preferred embodiment of this utility model, the locking mechanism 3 is installed on the rangefinder 1 which is fixedly connected to the belt conveyor. If the locking mechanism 3 is installed on another movable rangefinder 1, the structure of the telescopic component 2 may be deformed or damaged due to misoperation or external force during the adjustment process. Installing it on the fixed end can effectively avoid this situation and improve the reliability and service life of the device.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
