Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, and in particular to an anti-tipping early warning structure for the cover plate of a scraper conveyor in a fully mechanized mining face. Background Technology

[0002] Scraper conveyors are continuous transport equipment widely used in material transportation in industries such as coal mining, metal mining, chemical industry, and building materials, and they occupy a core position, especially in coal transportation in fully mechanized mining faces underground.

[0003] Currently, the cover plates of the scraper conveyor head in fully mechanized mining faces are fixed with bolts. When damaged scrapers, ironware, or debris are brought into the bottom of the scraper conveyor, they can easily damage the chain puller, lift up the cover plate, or damage the cover plate bolts, causing an accident where the cover plate is lifted. The cover plate is then caught in the bottom conveyor and is difficult to remove. It requires manual lifting of the conveyor or disassembly of the chain to remove the cover plate, which is time-consuming and affects the normal production of the working face.

[0004] Therefore, the cover plates of the scraper conveyor heads in the existing fully mechanized mining faces are all fixed with bolts. When damaged scrapers, ironware, or debris are brought into the bottom of the scraper conveyor, they can easily damage the chain puller, lift the cover plate, or damage the cover plate bolts, causing an accident where the cover plate is lifted. The cover plate is then caught in the bottom conveyor and is difficult to remove, requiring manual lifting of the conveyor or disassembly of the chain to remove the cover plate, which is time-consuming and affects the normal production of the working face. A cover plate anti-lifting early warning structure for the scraper conveyor in fully mechanized mining faces can be designed to dynamically monitor the working status of the cover plate, which is helpful for dynamic inspection and maintenance of the cover plate. Utility Model Content

[0005] To address the problem that the cover plates of the scraper conveyors in current fully mechanized mining faces are fixed with bolts, when damaged scrapers, ironware, or debris are brought into the bottom of the scraper conveyor, they can easily damage the chain drive, lift the cover plate, or damage the cover plate bolts, causing an accident where the cover plate is pulled into the bottom conveyor and is difficult to remove. It requires manual lifting of the conveyor or disassembly of the chain to remove the cover plate, which is time-consuming and affects the normal production of the working face.

[0006] The technical solution of this utility model is as follows: a cover plate anti-tipping early warning structure for a scraper conveyor in a fully mechanized mining face, including a frame, a chain derailleur, a half-roller, a cover plate, bolts, a mounting plate, a pressure sensor, a drive assembly, a control assembly, and an alarm assembly. The half-roller is fixedly installed inside the frame and is located around the rotating shaft of the chain derailleur. The half-roller is rotatably connected to the chain derailleur. The cover plate is located above the half-roller and is fixedly connected to the half-roller by two sets of bolts. A set of mounting plates is fixedly installed on both sides inside the frame. A pressure sensor is fixedly installed on the top of the mounting plate. The output end of the pressure sensor contacts the lower surface of the cover plate. The drive assembly is located on one side of the frame, the control assembly is located on the other side of the frame, and the alarm assembly is located above the control assembly.

[0007] Preferably, a drive assembly is installed to drive the chain derailleur to rotate, thereby enabling the scraper conveyor to operate. A half-roller and a cover plate are installed to shield and protect the chain derailleur. A pressure sensor is installed on a mounting plate, which can monitor the working status of the cover plate in real time. When the bolts loosen or the cover plate is lifted, the pressure on the pressure sensor changes, and the detected signal is transmitted to the control assembly. The control assembly is then set to stop the drive assembly in time, causing the scraper conveyor to stop promptly. This effectively prevents the escalation of accidents caused by slow human response or inadequate inspection. An alarm assembly is also set up to promptly notify the staff to carry out maintenance and repair, ensuring normal production afterwards.

[0008] Preferably, a fixing ring is fixedly installed above both the half roller and the cover plate, and a connecting ring is provided inside the fixing ring, with the fixing ring connected to the connecting ring.

[0009] Preferably, the drive assembly includes a support beam and a motor, with the support beam fixedly installed below the frame and the motor fixedly installed above the support beam, the motor being located on one side of the frame.

[0010] Preferably, the drive assembly includes a coupler and a gearbox. The gearbox is fixedly installed above the support beam, and the output end of the gearbox is fixedly connected to the derailleur. The coupler is located between the gearbox and the motor.

[0011] Preferably, the control assembly includes a support bracket and a control box, with the support bracket fixedly installed on one side of the frame and the control box fixedly installed on top of the support bracket.

[0012] Preferably, the control box contains a processing module and an operation module, and the control module and the processing module are connected by wiring.

[0013] Preferably, the alarm component includes a warning light and an alarm horn. The warning light is fixedly installed on the top of the control box, and the alarm horn is located on the top of the control box. Both the warning light and the alarm horn are connected to the control module wiring.

[0014] The beneficial effects of this utility model are:

[0015] 1. The working status of the cover plate can be detected in real time through the pressure sensor. When the bolts are loose or the cover plate is lifted, the pressure sensor changes and transmits the detected signal to the processing module inside the control box. The control module controls the motor to stop it in time, so that the scraper conveyor can be stopped in time. This effectively prevents the accident from escalating due to slow human response time or inadequate inspection. Then, the control module controls the warning lights and alarm horn to issue audible and visual alarms to remind relevant personnel to carry out timely inspection and maintenance to ensure normal production in the future.

[0016] 2. The cover plate and the half roller can be flexibly connected by the fixing ring and the connecting ring. When the bolts are loose or the cover plate is lifted, the fixing ring and the connecting ring work together to prevent the lifted cover plate from flying far away and injuring people, and also to prevent the cover plate from falling under the scraper conveyor and affecting normal production.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 and Figure 2This utility model provides an embodiment of an anti-tipping warning structure for the cover plate 4 of a scraper conveyor in a fully mechanized mining face. The structure includes a frame 1, a chain derailleur 2, a half-roller 3, a cover plate 4, bolts 401, mounting plates 5, a pressure sensor 501, a drive assembly, a control assembly, and an alarm assembly. The half-roller 3 is fixedly installed inside the frame 1, located around the rotating shaft of the chain derailleur 2, and rotatably connected to the chain derailleur 2. The cover plate 4 is positioned above the half-roller 3 and is fixedly connected to the half-roller 3 by two sets of bolts 401. Mounting plates 5 are fixedly installed on both sides inside the frame 1. A pressure sensor 501 is fixedly installed on the top of the mounting plates 5, and the output end of the pressure sensor 501 contacts the lower surface of the cover plate 4. The drive assembly is located on one side of the frame 1, the control assembly is located on the other side of the frame 1, and the alarm assembly... The component is positioned above the control assembly. The drive assembly drives the chain derailleur 2 to rotate, thus enabling the scraper conveyor to operate. The chain derailleur 2 is shielded and protected by the half-roller 3 and cover plate 4. The pressure sensor 501 is installed on the mounting plate 5. The pressure sensor 501 can monitor the working status of the cover plate 4 in real time. When the bolt 401 loosens or the cover plate 4 is lifted, the pressure on the pressure sensor 501 changes, transmitting the detected signal to the control assembly. The control assembly then promptly stops the drive assembly, causing the scraper conveyor to stop immediately. This effectively prevents the escalation of accidents caused by slow human response or inadequate inspection. An alarm assembly promptly notifies personnel of the situation for maintenance and repair, ensuring normal production afterwards.

[0024] Please see Figure 1 and Figure 2In this embodiment, a fixing ring 6 is fixedly installed above both the half-roller 3 and the cover plate 4. A connecting ring 601 is provided inside the fixing ring 6, and the fixing ring 6 is connected to the connecting ring 601. By setting the fixing ring 6 and the connecting ring 601, a flexible connection can be made between the cover plate 4 and the half-roller 3. When the bolt 401 loosens or the cover plate 4 is lifted, it can prevent the lifted cover plate 4 from injuring people and also prevent the cover plate 4 from falling below the scraper conveyor. The drive assembly includes a support beam 701 and a motor 702. The support beam 701 is fixedly installed below the frame 1, and the motor 702 is fixedly installed above the support beam 701. The motor 702 is located on one side of the frame 1; the drive assembly includes a coupler 703 and a gearbox 704. The gearbox 704 is fixedly installed above the support beam 701. The output end of the gearbox 704 is fixedly connected to the derailleur 2. The coupler 703 is located between the gearbox 704 and the motor 702. The motor 702 and the gearbox 704 are installed by setting the support beam 701. The motor 702 can provide power to the gearbox 704 through the coupler 703. The gearbox 704 increases the torque to drive the derailleur 2 to rotate. The coupler 703 can protect the motor 702.

[0025] Please see Figure 3 and Figure 4 In this embodiment, the control component includes a support bracket 801 and a control box 802. The support bracket 801 is fixedly installed on one side of the frame 1, and the control box 802 is fixedly installed above the support bracket 801. The control box 802 contains a processing module 803 and a control module 804. The support bracket 801 secures the control box 802 to one side of the frame 1, and the control box 802 houses and protects the internal processing module 803 and control module 804. The processing module 803 transmits data to the pressure sensor 501. The control module 804 controls the drive components and alarm components. The alarm components include a warning light 901 and an alarm horn 902. The warning light 901 is fixedly installed on the top of the control box 802, and the alarm horn 902 is also located on the top of the control box 802. Both the warning light 901 and the alarm horn 902 are connected to the control module 804. When the bolt 401 is loosened or the cover 4 is lifted, an audible and visual alarm can be triggered by the warning light 901 and the alarm horn 902 to remind relevant personnel to carry out timely inspection and maintenance, ensuring normal production.

[0026] When working, the motor 702 can provide power to the gearbox 704 through the coupler 703. By setting the gearbox 704 to increase the torque, the derailleur 2 can be rotated. The coupler 703 can protect the motor 702.

[0027] The derailleur 2 is shielded and protected by the half roller 3 and the cover plate 4. The cover plate 4 can be installed and fixed by the bolt 401. The pressure sensor 501 can detect the working status of the cover plate 4 in real time. When the bolt 401 is loose or the cover plate 4 is lifted, the pressure sensor 501 changes pressure and transmits the detected signal to the processing module 803 inside the control box 802. The control module controls the motor 702 to stop it in time, so that the scraper conveyor can stop in time and effectively prevent the accident from escalating due to slow human reaction time or inadequate inspection.

[0028] Then, the control module is used to control the warning light 901 and the alarm horn 902, which will issue audible and visual alarms to remind relevant personnel to carry out timely inspection and maintenance to ensure normal production.

[0029] Through the above steps, the working status of the cover plate 4 can be detected in real time by the pressure sensor 501. When the bolt 401 loosens or the cover plate 4 is lifted, the pressure on the pressure sensor 501 changes, and the detected signal is transmitted to the processing module 803 inside the control box 802. The control module controls the motor 702 to stop it in time, so that the scraper conveyor can be stopped in time. This effectively prevents the escalation of accidents caused by slow reaction time or inadequate inspection by humans. This solves the problem that the cover plate 4 of the scraper conveyor head of the current fully mechanized mining face is fixed with fixing bolts 401. When the bottom of the scraper conveyor is brought in damaged scrapers, ironware or debris, it is easy to damage the chain derailleur 2, lift the cover plate 4 or damage the bolt 401 of the cover plate 4, causing the cover plate 4 to be lifted. The cover plate 4 is caught in the bottom chute and is not easy to remove. It is necessary to manually lift the chute or disassemble the chain to remove the cover plate 4, which takes a long time and affects the normal production of the working face.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
