Description

Technical Field

[0001] This utility model relates to the field of conveyor bridge technology, and in particular to an automatic washing device for conveyor bridges. Background Technology

[0002] Coal-fired power plants typically utilize conveyor bridges for coal transport, a harsh environment that generates large amounts of coal dust that accumulates on the bridge floor and within cable trays. This can potentially impact equipment operation, pollute the surrounding environment, and affect the health and well-being of nearby residents. Therefore, regular cleaning is essential to prevent prolonged accumulation of coal dust and its potential for spontaneous combustion, which could lead to safety accidents. Currently, coal dust accumulation on conveyor bridges is generally handled manually and periodically, but this method is costly, poses safety hazards, and is inefficient and ineffective. Utility Model Content

[0003] The technical problem this utility model aims to solve is that the accumulated dust and coal in the existing coal conveying system trestle are generally washed manually on a regular basis. However, the labor cost is high, safety hazards are easy to occur, and the washing effect is poor and the washing efficiency is low.

[0004] To address the aforementioned problems, this utility model provides an automatic flushing device for a conveyor bridge. A conveyor is mounted on the bridge frame, with main pipes and flushing pipes on both sides of the conveyor. Multiple nozzles are mounted on the flushing pipes. A box is horizontally slidable on the bridge frame, and a motor is housed within the box. The motor's output shaft is capable of forward and reverse rotation and is connected to a column. Multiple toothed grooves are spaced circumferentially on the outer circumference of the column. The flushing pipe is rotatably mounted on the box, and a toothed ring corresponding to and meshing with the toothed grooves is installed on the flushing pipe.

[0005] The automatic washing device for the conveyor bridge provided by this utility model also has the following technical features:

[0006] The end of the column away from the motor has a threaded hole, and the bridge frame has a screw corresponding to the threaded hole.

[0007] The cable tray is provided with a mounting plate, on which two protruding plates are provided opposite each other, and a horizontal guide rod is provided between the two protruding plates. The box body is provided with a horizontal guide hole corresponding to the horizontal guide rod; a screw is provided on one of the protruding plates.

[0008] The cross-section of the horizontal guide rod is circular, and two are arranged opposite each other vertically.

[0009] The main pipeline is connected to the flushing pipe via a flexible hose, and a valve body is installed on the flexible hose.

[0010] Multiple nozzles are spaced apart along the length of the flushing pipe, and adjacent nozzles are staggered along the circumference of the flushing pipe.

[0011] This utility model has the following beneficial effects: the main pipeline supplies water to the flushing pipe and automatically flushes the cable tray through the nozzle, reducing the cost of use and avoiding safety hazards; at the same time, the output shaft of the motor drives the column to rotate back and forth, and the tooth groove and tooth ring mesh, so that the flushing pipe swings back and forth while moving horizontally along the cable tray with the box, thereby increasing the flushing range and flushing effect of the nozzle, and thus improving the flushing efficiency.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0016] like Figures 1 to 3 As shown, the automatic flushing device for the conveyor bridge of this utility model includes a conveyor 11 on the bridge frame 10. Both sides of the conveyor 11 are provided with interconnected main pipes 12 and flushing pipes 13. Multiple nozzles 14 are provided on the flushing pipes 13. A box 21 is horizontally slidably provided on the bridge frame 10. A motor 22 is provided inside the box 21. The output shaft of the motor 22 can rotate in both directions and is connected to a column 23. Multiple toothed grooves 24 are spaced apart along the circumference of the outer circumference of the column 23. The flushing pipe 13 is rotatably mounted on the box 21, and a toothed ring 25 that meshes with the toothed grooves 24 is installed on the flushing pipe 13.

[0017] The main pipe 12 supplies water to the flushing pipe 13 and automatically flushes the cable tray 10 through the nozzle 14, reducing operating costs and avoiding safety hazards. At the same time, the output shaft of the motor 22 drives the column 23 to rotate back and forth, and the toothed groove 24 meshes with the toothed ring 25, so that the flushing pipe 13 swings back and forth while moving horizontally along the cable tray 10 with the box 21, thereby increasing the flushing range and flushing effect of the nozzle 14 and improving the flushing efficiency.

[0018] The main pipe 12 and flushing pipe 13 are both installed along the running direction of the conveyor 11. The main pipe 12 is a welded steel pipe of DN80 or DN50. The flushing pipe 13 is a galvanized steel pipe, and the nozzle 14 is a fan-shaped nozzle with medium flow rate and orifice diameter to avoid atomization of water spray and reduce the flushing effect. The housing 21 is sealed and waterproof, dustproof, and corrosion-resistant. It can be formed by two half-boxes to facilitate the installation of related drive components. The housing 21 contains a reducer and control module corresponding to the motor 22. The power supply can be installed inside the housing 21 or connected to the motor 22 through an external wire.

[0019] Those skilled in the art can select and configure the motor 22, gear 24, and gear ring 25 according to actual conditions, so that the flushing pipe 13 can reciprocate from 0 to 80° in the vertical plane, and the flushing water column will be pushed downwards towards the conveyor 11, thereby achieving reciprocating sweeping. Steps (not shown) are provided between the flushing pipe 13 and the conveyor 11. In addition, to avoid excessive water consumption and reduced flushing water pressure at the same time, all trestles are arranged in sequence, flushing sequentially from high to low, achieving relay flushing and saving water.

[0020] Preferably, the end of the column 23 away from the motor 22 is provided with a threaded hole, and the bridge frame 10 is provided with a screw 26 corresponding to the threaded hole.

[0021] The output shaft of motor 22 drives column 23 to rotate back and forth. Screw 26 is connected to threaded hole. Since screw 26 is set on bridge frame 10, column 23, box 21 and flushing pipe 13 can slide horizontally back and forth along bridge frame 10.

[0022] The threaded hole is coaxially formed on the column 23, and the box 21 is provided with a through hole for the screw 26 to pass through.

[0023] Preferably, the cable tray 10 is provided with a mounting plate 27, and two protruding plates 28 are provided opposite to each other on the mounting plate 27. A horizontal guide rod 29 is provided between the two protruding plates 28, and a horizontal guide hole corresponding to the horizontal guide rod 29 is provided on the box body 21; a screw 26 is provided on one of the protruding plates 28.

[0024] The mounting plate 27 is bolted to the cable tray 10 to make it detachable.

[0025] Preferably, the cross-section of the horizontal guide rod 29 is circular and two are arranged opposite each other vertically. Correspondingly, two horizontal guide holes are opened on the box body 21. Of course, only one horizontal guide rod 29 can be provided, and its cross-section must be square, elliptical or other non-circular. Of course, other guiding mechanisms for the box body 21 to slide horizontally along the cable tray 10 can also be provided. For example, the cable tray 10 is provided with a guide groove and the box body 21 is provided with a corresponding guide rod, or conversely, the cable tray 10 is provided with a guide rod and the box body 21 is provided with a corresponding guide groove. There are no restrictions here.

[0026] Preferably, the main pipe 12 is connected to the flushing pipe 13 via a hose 15, and a valve body 16 is provided on the hose 15.

[0027] The hose 15 is made of high-pressure nylon steel wire hose, which is resistant to high pressure, deformation, and corrosion, and can withstand the displacement changes of the flushing pipe 13 and the main pipe 12 when they rotate. The valve body 16 is preferably a solenoid valve, capable of receiving control signals to automatically shut off the hose 15. An emergency start / stop button is provided on the cable tray 10 for manual start / stop of flushing. Alternatively, flushing can be automatic. After a certain period of production downtime, the control platform can send an opening command to the control modules of the valve body 16 and motor 22 of the corresponding trestle section, causing the trestle to enter automatic flushing mode, which automatically shuts off after a certain flushing time. Additionally, an audible alarm device is installed on the cable tray 10 to provide an audible warning before flushing begins.

[0028] Preferably, multiple nozzles 14 are spaced apart along the length of the flushing pipe 13, and adjacent nozzles 14 are staggered along the circumference of the flushing pipe 13; the axes of adjacent nozzles 14 intersect at the axis of the flushing pipe 13 and form a certain angle, thereby increasing the flushing range in both the vertical and horizontal directions.

[0029] The working principle of this utility model is as follows:

[0030] When the cable tray 10 needs to be flushed, the valve body 16 is opened, and the main pipe 12 supplies water to the flushing pipe 13 through the hose 15. The cable tray 10 is then automatically flushed through the nozzle 14, reducing operating costs and avoiding safety hazards. At the same time, the output shaft of the motor 22 drives the column 23 to rotate back and forth. The toothed groove 24 meshes with the toothed ring 25, causing the flushing pipe 13 to swing back and forth. Meanwhile, the screw 26 is connected to the threaded hole on the column 23. Since the screw 26 is set on the cable tray 10, the column 23, the box 21, and the flushing pipe 13 can slide horizontally back and forth along the cable tray 10. This allows the nozzle 14 to swing back and forth around the flushing pipe 13 and move axially back and forth, increasing the flushing range and effect of the nozzle 14, thereby improving flushing efficiency.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
