Description

Elevator fault early warning device and elevator applying same

Technical Field

The application relates to the technical field of industrial manufacturing, in particular to a fault early warning device of a hoisting machine and the hoisting machine applying the fault early warning device.

Background

The bucket elevator is a continuous conveying machine for vertically lifting materials by utilizing a series of hoppers uniformly and fixedly connected to an endless traction member, and the bucket elevator is widely applied to the industries of cement manufacturing, building materials, chemical engineering and the like by utilizing a series of hoppers fixedly connected to a traction chain or a belt to convey bulk materials upwards in the vertical direction or the direction close to the vertical direction.

Because the cement plant and the chemical plant usually need 24 hours to operate continuously, the hoister needs to work continuously, and therefore, the time for stopping for overhauling is basically avoided. However, the bucket elevator generally lifts heavy materials, and the problems of abrasion, cracks, loss and the like of the bucket, and the problems of extension deformation, serious pin hole abrasion, pin falling and the like of a traction chain (a plate chain or a ring chain) or a belt can occur after long-term operation. If the elevator cannot be found in time and is stopped for maintenance, the secondary damage of the elevator is easily caused.

In addition, because of dust, the bucket elevator needs a fully-closed shell, so that the condition of a hopper and a traction chain (or a belt) cannot be checked at any time, and the phenomenon that the bucket elevator generates secondary damage accidents often occurs. Once this occurs, the production line is essentially shut down for about a week for emergency repairs, which, in addition to being expensive to repair, results in greater losses due to the shutdown. Therefore, how to effectively perform fault early warning on the hoister and timely perform shutdown and first-aid repair is a difficult problem in the industry.

Detailed Description

For better understanding of the technical solutions of the present application, the following detailed descriptions of the embodiments of the present application are provided with reference to the accompanying drawings.

It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be understood that the term "and/or" as used herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., A and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Referring to fig. 1, a schematic structural diagram of a bucket elevator according to an embodiment of the present application is provided. As shown in fig. 1, the bucket elevator 100 includes a top roller 102 and a bottom roller 103, a belt 104 is sleeved on the top roller 102 and the bottom roller 103, and a series of hoppers 105 are fixed on the belt 104. In addition, the bottom of the bucket elevator 100 is provided with a feeding bin 107, the top is provided with a discharging bin 106, the belt 104 drives the hopper 105 to rotate through the rotation of the top roller 102 and the bottom roller 103, and then the material in the feeding bin 107 is lifted to the position of the discharging bin 106 and discharged at the outlet of the discharging bin 106.

It should be noted that fig. 1 is only an exemplary description of the embodiments of the present application, and should not be taken as limiting the scope of the present application. For example, the bucket elevator 100 may be a bucket drag chain elevator, and it is understood that when the bucket elevator 100 is a bucket drag chain elevator, the top roller 102 and the bottom roller 103 are positioned as sprockets, the belt 104 is positioned as a drag chain, and the hopper 105 is connected to the drag chain. In addition, the technical solution provided in the embodiment of the present application may be applied to other types of hoists besides the bucket elevator 100, and the present application is not particularly limited thereto.

In order to avoid dust emission, a casing 101 is usually provided on the outer side of the bucket elevator 100, and the casing 101 may be a fully enclosed casing. Although the problem of dust emission can be solved by the totally enclosed casing, the totally enclosed casing makes the inside of the bucket elevator 100 invisible, and the condition of the hopper 105 and the belt 104 cannot be checked at any time. The bucket elevator 100 generally has a heavy material ratio, and long-term operation may cause abrasion, cracks, and loss of the hopper 105, elongation and deformation of the belt 104, falling of pins connecting the belt 104 and the hopper 105, and severe abrasion of pin holes. If the elevator cannot be found in time and is stopped for maintenance, the secondary damage of the elevator is easily caused.

In order to solve the problem, an embodiment of the present application provides a hoist fault early warning device 200, which is described in detail below with reference to the accompanying drawings.

Referring to fig. 2, a perspective view of a fault warning device for a hoist according to an embodiment of the present disclosure is shown; referring to fig. 3, a front view of a fault warning device for a hoist provided in the embodiment of the present application is shown; referring to fig. 4, an explosion diagram of an elevator fault early warning device provided in the embodiment of the present application is shown. As shown in fig. 2 in combination with fig. 3 and 4, the elevator fault early warning device 200 includes a transparent bottom plate 201, and an image acquisition module 202, a purging and dust removing module 203, and a power supply module 204 are disposed on the transparent bottom plate 201. During the use, set up the opening at the casing 101 relevant position of lifting machine, install this lifting machine trouble early warning device 200 at the opening part, gather the inside image of opening through image acquisition module 202, and then realize the trouble early warning.

For convenience of description, both side surfaces of the transparent base 201 are referred to as a first side surface 206 and a second side surface 207, respectively. The image capturing module 202 is disposed on the first side surface 206 of the transparent base plate 201, when the image capturing module is mounted, the first side surface 206 is located on the outer side of the housing 101 of the elevator, the second side surface 207 is located on the inner side of the housing 101 of the elevator, the lens of the image capturing module 202 faces the transparent base plate 201, and the image is captured through the transparent base plate 201 toward the second side surface 207 of the transparent base plate 201. That is, the image capturing module 202 is located outside the transparent base plate 201, and captures an image of the inside of the transparent base plate 201, that is, the inside of the housing 101 of the elevator. Because there is raise dust in the inside of the casing 101 of lifting machine, therefore, set up image acquisition module 202 in the outside of transparent bottom plate 201 can avoid raise dust to cause the interference to image acquisition module 202. In a specific implementation, the transparent substrate 201 may be high-strength transparent glass fiber reinforced plastic, and the image capturing module 202 may be an industrial camera.

In addition, the housing 101 of the elevator is a fully closed shell, so that light inside the housing 101 is poor. In order to improve the image acquisition effect, a light supplement lamp may be further integrated on the image acquisition module 202, and the light supplement lamp is used for supplementing light when the image acquisition module 202 performs image acquisition. Of course, the fill-in light may also be disposed separately from the image acquisition module 202, which is not limited in this embodiment of the application. It can be understood that, in order to avoid the dust flying inside the casing 101 of the elevator from interfering with the light supplement lamp, the light supplement lamp is preferably disposed on the first side surface 206 of the transparent bottom plate 201, i.e., outside the casing 101 of the elevator.

The blowing and dust removing module 203 is used for blowing dust on the second side surface 207 of the transparent bottom plate 201, so that the phenomenon that the raised dust inside the shell 101 of the hoister influences the image acquisition effect when image acquisition is carried out is avoided. In an alternative embodiment, the purging and dust-removing module 203 is disposed on the first side 206 of the transparent bottom plate 201, and the air outlet of the purging and dust-removing module 203 is disposed on the second side 207 of the transparent bottom plate 201, as shown in fig. 4. By adopting the arrangement mode, the interference of the raised dust in the shell 101 of the hoister on the sweeping and dedusting module 203 can be reduced as much as possible. In specific implementation, the purging and dedusting module 203 can be an air blower, the air blower is arranged on the first side surface 206 of the transparent bottom plate 201, an air outlet of the air blower is connected with an air outlet pipe, and an air outlet of the air outlet pipe is arranged at a corresponding position of the second side surface 207. It can be appreciated that the purge region of the outlet should match the image capture region of the image capture module 202.

The power supply module 204 is used for supplying power to the image acquisition module 202 and the purging and dust removal module 203. In an alternative embodiment the power supply module 204 is arranged at the first side 206 of the transparent bottom plate 201, i.e. outside the housing 101 of the hoisting machine.

In an alternative embodiment, the image capturing module 202 may further integrate a data processing unit, which is configured to perform fault identification according to the captured image. For example, the data processing unit may be embedded with an AI algorithm, by which the captured images are identified to further determine whether there is wear or other defects at the positions of the elevator's hopper 105, belt 104 or plate chains, pin holes, pins, etc. It can be understood that in a specific implementation, the data processing unit may also be disposed in the background, and the image acquired by the image acquisition module 202 is transmitted to the background through the communication module to perform corresponding data processing such as image recognition. The communication module CAN be a wired communication module or a wireless communication module, including but not limited to communication modes such as ethernet, serial bus, 5G, 4G, NB, wifi, and the like, and the communication protocol includes but not limited to protocols such as MQTT, CAN bus, OPC, PROFITBUS, and the like.

It can be understood that the hoisting machine fault early warning device 200 may further include a bolt 205, a bolt 205 hole matched with the bolt 205 is provided on the transparent bottom plate 201, and the hoisting machine fault early warning device 200 may be fixed on the casing 101 of the hoisting machine through the bolt 205. Of course, a person skilled in the art may also fix the elevator fault warning device 200 in other ways, which is not limited in the embodiment of the present application.

Corresponding to the above elevator fault early warning device 200, the embodiment of the present application further provides an elevator with the elevator fault early warning device 200, which is described in detail below with reference to the accompanying drawings.

Referring to fig. 5, a schematic opening diagram of a bucket elevator according to an embodiment of the present disclosure is shown. As shown in fig. 5, the casing 101 of the hoist is a totally enclosed casing, and the position of the opening 501 in the casing 101, that is, the position where the hoist malfunction early warning apparatus 200 needs to be installed, corresponds to the position where malfunction detection is needed. In the embodiment shown in fig. 5, the position of the opening 501 corresponds to the side of the belt 104 and the hopper 105. Since the wear of the belt 104 and the hopper 105 and the fit of the pin hole and the pin are more easily distinguished by the sides of the belt 104 and the hopper 105, more accurate failure warning results can be obtained by disposing the position of the opening 501 at the sides of the belt 104 and the hopper 105. Accordingly, in the case of a bucket plate chain elevator, the location of the opening 501 corresponds to the side of the plate chain and the hopper 105.

Referring to fig. 6, a schematic structural diagram of a bucket elevator with an elevator fault early warning device according to an embodiment of the present application is provided. As shown in fig. 6, the lifter failure early warning device 200 is fixed at the opening 501 by the bolt 205, wherein the second side 207 of the transparent bottom plate 201 faces the inside of the bucket lifter 100, the first side 206 faces the outside of the bucket lifter 100, and the lens of the image capturing module 202 and the lifting bin (inside the housing 101) are isolated by the transparent bottom plate 201, so as to prevent dust accumulated on the lens from affecting the image capturing effect. In addition, the transparent bottom plate 201 also isolates the blowing dust removal module 203, the light supplement lamp, the power supply module 204 and the like from the lifting bin, and dust affects the blowing dust removal module 203, the light supplement lamp, the power supply module 204 and the like. It should be noted that the air outlet of the purging and dust removing module 203 needs to extend into the interior of the lifting bin through the air outlet pipe so as to purge the dust on the second side surface 207 of the transparent bottom plate 201.

In the embodiment of the present application, since the position of the opening 501 corresponds to the side surfaces of the belt 104 and the hopper 105, the image capturing area of the elevator malfunction early warning apparatus 200 can cover the side surfaces of the belt 104 and the hopper 105. After the power is turned on, the elevator fault early warning device 200 may perform image acquisition at a preset time interval so as to perform fault early warning in real time. Of course, the person skilled in the art can dispose the opening 501 at other positions according to the actual requirement, and the embodiment of the present application is not limited thereto.

In the embodiments of the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, and means that there may be three relationships, for example, a and/or B, and may mean that a exists alone, a and B exist simultaneously, and B exists alone. Wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" and similar expressions refer to any combination of these items, including any combination of singular or plural items.
