Description

[0001] The invention relates to the technical field of belt conveyor monitoring, and in particular to a method for installing an external chip of an address encoder and a belt conveyor monitoring and control system. Background Art

[0002] The coal conveyor belt is an important part of the coal conveying system in a thermal power plant. In order to prevent the coal conveyor belt from stopping operation in time when an emergency occurs during use, protection devices such as pull ropes, deviation, slippage, tearing, and coal blocking are usually installed on the equipment to protect personnel and equipment. Due to the large number and types of protection devices and different installation positions, when a group of protection devices (pull ropes, deviation, slippage, tearing, coal blocking, etc.) fails, only a group of alarm signals can be sent to the program control, and the position cannot be accurately reported, which specific protection device alarms, resulting in low inspection efficiency for operating personnel and maintenance personnel needing to check one by one during maintenance, which invisibly increases the workload and low work efficiency, affecting the company's safety production benefits. Therefore, a real-time monitoring system for protection devices such as rope pulling, deviation, slipping, tearing, and coal blockage based on an address encoder is designed. This is of great significance to the safe use of the coal conveyor belt. Since the various existing belt conveyor comprehensive protection devices have been installed on the belt conveyor and used for a period of time, it is necessary to later install and connect the address encoder part and avoid the influence of vibration on the address encoder part when the belt conveyor is in use.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0039] Example 1

[0040] Reference Figure 1-Figure 4 , which is the first embodiment of the present invention, provides a method for installing an external chip of an address encoder, a circular hole is opened on the outer shell of various belt machine comprehensive protection devices, the external chip of the address encoder is installed on the belt machine comprehensive protection device through the circular hole, and the external chip of the address encoder is electrically connected to the chip 102 inside the various belt machine comprehensive protection devices through wires.

[0041] The address encoder external chip includes a main body part 100 and a connecting part 200. The main body part 100 can be detachably installed on various belt conveyor comprehensive protection devices through the connecting part 200. The main body part 100 includes a shell 101 and a chip 102 installed inside the shell 101. The chip 102 is integrated with an address encoder unit and a wireless transmission unit. The shell 101 is provided with a plurality of indicator lights 105 and a fault reset button 106. The indicator lights 105 and the fault reset button 106 are electrically connected to the chip 102 through wires. A groove 103 and a rotary lock 104 are provided below the shell 101; the connecting part 200 includes an annular air cushion ring 201 installed in the groove 103, and an air filling part 202 installed inside the air cushion ring 201. The air filling part 202 is used for manually filling the air cushion ring 201 in the early stage and automatically filling the air cushion ring 201 in the later stage, and the air cushion ring 201 and the rotary lock part 104 are connected by a hose.

[0042] In this embodiment, a circular hole is opened on the outer shell of various existing belt conveyor integrated protection devices, and then the address encoder external chip inserts the mounting seat 101b into the circular hole, and then the air cushion ring 201 and the rotary lock member 104 are injected with air through the air filling member 202, so that the rotary lock member 104 is expanded on the inner wall of the circular hole and the air cushion ring 201 is also expanded in the circular hole, thereby installing the address encoder external chip on various existing belt conveyor integrated protection devices, and finally, the address encoder external chip is electrically connected to the chip 102 in various existing belt conveyor integrated protection devices through wires, so as to ensure the normal use of the address encoder external chip, so that when a belt conveyor integrated protection device performs a corresponding operation, the address encoder external chip can send the corresponding position to the control component in time, so that the background staff can monitor it conveniently. At the same time, the indicator light 105 set by itself will also flash, and the urgency can be judged according to the set flashing color. For example, when it is installed on the deviation switch, the deviation can be light or heavy. Our indicator light is set to turn green when the deviation is light, and turn red when the deviation is heavy. If it is installed on the stretching switch, the red light will turn on when there is a stretching action, which is particularly intuitive and convenient for on-site staff to observe in time.

[0043] Example 2

[0044] Reference Figure 2-Figure 8 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that the housing 101 is divided into an upper cover shell 101a and a lower mounting seat 101b, the lower surface of the mounting seat 101b is provided with a flange 101c for plugging into a circular hole, a through hole 101d is provided at the center of the mounting seat 101b, a groove 103 is located on the lower side of the mounting seat 101b, and a rotary lock 104 is installed in an annular groove 101e provided on the outer wall of the flange 101c. The cross-sections of the groove 103 and the gasket 201 located therein are both symmetrical L-shaped.

[0045] It should be noted that an annular air cushion ring 201 is provided at the corner of the lower surface of the mounting seat 101b, that is, an air cushion ring 201 is provided at the contact position between the mounting seat 101b and the circular hole. Since the existing various belt conveyor integrated protection devices are in direct contact with the belt conveyor or are installed on the belt conveyor, the belt conveyor will vibrate during actual use, causing the shell of the existing various belt conveyor integrated protection devices to vibrate, and then the address encoder external chip installed on the shell of the existing various belt conveyor integrated protection devices will also be vibrated. In order to avoid the impact of this part of the vibration on the address encoder external chip, In order to influence the service life and use effect, the part where the circular hole contacts the mounting seat 101b is filled with the air gasket 201. On the one hand, the air gasket 201 is used to seal the circular hole and the mounting seat 101b to prevent foreign matter from entering the outer shell of various existing belt conveyor comprehensive protection devices through the circular hole and affecting the internal electrical components. At the same time, the circular hole is firmly clamped together with the rotary lock 104 to ensure that the mounting seat 101b is firmly installed. On the other hand, the air gasket 201 can also be used to reduce the vibration transmitted from the circular hole to avoid affecting the external chip of the address encoder.

[0046] The inner wall of the gasket 201 is provided with two air inlet holes 201a, and an insertion hole 201b is provided on the outer wall of the gasket 201, which is located directly opposite to one of the air inlet holes 201a. The two ends of the gas filling member 202 are connected to the two air inlet holes 201a. The gas filling member 202 includes a cylinder 202a, and the cylinder 202a has two air chambers 202b on the left and right. One end of each air chamber 202b is provided with an air suction hole 202c and a piston 202d, and the two air suction holes 202c are symmetrically arranged in the cylinder 202a. Two air outlet holes 202g are respectively provided at the two ends of the cylinder 202a, and each end of the air chamber 202b corresponds to an air outlet hole 202g. The cylinder 202a is also provided with a piston 202d that drives the two pistons 202c. d is a transmission member 202e that moves synchronously, and the transmission member 202e includes two pulleys 202e-1 and a belt 202e-2 mounted on the two pulleys 202e-1. Two pistons 202d are respectively installed on both sides of the same side of the belt 202e-2 and are point-symmetrically distributed. A detachable control rod 202f is rotatably arranged on the upper part of one of the pistons 202d, and the control rod 202f passes through the air chamber 202b, the air outlet 202g, the air inlet 201a and the insertion hole 201b.

[0047] It should be noted that if Figure 7As shown, the air chamber 202b is divided into the north air chamber 202b and the south air chamber 202b with north at the top, south at the bottom, west on the left and east on the right. The two air outlet holes 202g on the left and right of the north air chamber 202b are respectively the northwest air outlet hole 202g and the northeast air outlet hole 202g, and the two air outlet holes 202g on the left and right of the south air chamber 202b are respectively the southwest air outlet hole 202g and the southeast air outlet hole 202g. A northwest air intake hole 202c is opened at the northwest air outlet hole 202g in the north air chamber 202b, and a southeast air intake hole 202c is opened at the southeast air outlet hole 202g in the south air chamber 202b. During normal use, the two air inlet holes 201a connected to the left and right of the gas filling member 202 are connected to the northeast air outlet 202g and the southwest air outlet 202g respectively. At this time, the control rod 202f passes through the insertion hole 201b, and the air inlet hole 201a and the southwest air outlet 202g are screwed with the piston 202d in the south air chamber 202b, and the reciprocating movement of the control rod 202f drives the piston 202d to reciprocate in the south air chamber 202b. When the piston 202d moves away from the southeast air intake hole 202c in the south air chamber 202b, air is sucked into the south air chamber 202b from the outside. When the piston 202d is in the south air chamber 202b, the air is sucked into the south air chamber 202b from the outside. When the south air chamber 202b moves toward the southeast air intake hole 202c, the one-way valve on the piston 202d opens, allowing the gas to pass through and be introduced into the other side of the south air chamber 202b and enter the air cushion 201 through the southwest air outlet 202g, inflating this part of the air cushion 201. Similarly, since the two pistons 202d are driven by the belt 202e-2 to move synchronously in the opposite direction, the other piston 202d introduces the gas sucked in from the north air chamber 202b into the air cushion 201 through the northeast air outlet 202g, inflating this part of the air cushion 201, and completing the inflation of the air cushion 201.

[0048] After that, the control rod 202f pulls the piston 202d in each air chamber 202b away from the air intake hole 202c, so that a certain amount of air is stored in each air chamber 202b, and then the air filling member 202 is driven to rotate by the control rod 202f. After the control rod 202f is removed, the control rod 202f is inserted into another northwest air outlet 202g, and the air filling member 202 is continued to rotate until the air filling member 202 rotates 180 degrees, so that the south air chamber 202b and the north air chamber 202b are exchanged, and the two air inlet holes 201 connected to the left and right of the air filling member 202 are closed. a is respectively connected with the southeast air outlet 202g and the northwest air outlet 202g, while the northeast air outlet 202g and the southwest air outlet 202g are blocked. At this time, the control rod 202f can be removed and the insertion hole 201b can be blocked. Since a torsion spring is arranged inside the pulley 202e-1, it is used to drive the belt 202e-2 and the two pistons 202d on the belt 202e-2 to return to their positions, so that when there is a lack of air inside the air cushion 201, the air in the air chamber 202b can be introduced into the air cushion 201 to keep the air cushion 201 always full.

[0049] The rotary lock member 104 includes a plurality of arcuate rotary blades 104a arranged at equal intervals in a ring shape, one end of each arcuate rotary blade 104a is rotatably arranged in an annular groove 101e, and an accommodating groove 104b is provided on the inner wall of the arcuate rotary blade 104a, and a telescopic air cylinder 104c corresponding to the arcuate rotary blade 104a is also provided in the annular groove 101e, one end of the telescopic air cylinder 104c is connected to the interior of the air cushion ring 201 through a hose, and an extended end of the telescopic air cylinder 104c is rotatably connected to the accommodating groove 104b on the inner wall of the arcuate rotary blade 104a through a hinge piece 104d, and a rubber pad 104e is provided on the upper surface of the arcuate rotary blade 104a.

[0050] It should be noted that the arc-shaped rotary blade 104a, the telescopic gas cylinder 104c and the hinged plate 104d form a single piece, and the entire rotary lock member 104 is composed of a plurality of single pieces distributed in an annular shape with equal spacing, wherein one end of the telescopic gas cylinder 104c and the arc-shaped rotary blade 104a are both hinged on the wall of the annular groove 101e, and when retracted, the telescopic gas cylinder 104c is located in the accommodating groove 104b of the arc-shaped rotary blade 104a, and the other end of the telescopic gas cylinder 104c is hinged to one end of the hinged plate 104d, and the other end of the hinged plate 104d is hinged to one end of the accommodating groove 104b of the arc-shaped rotary blade 104a. In this way, when the telescopic cylinder 104c is extended by gas injection, the telescopic cylinder 104c will push the free end of the arc-shaped rotary blade 104a outward through the hinge piece 104d, and push the arc-shaped rotary blade 104a out, so that the arc-shaped rotary blade 104a is stuck on the inner wall of the circular hole, and then the mounting seat 101b is stuck on the inner wall of the circular hole, and finally the entire address encoder external chip is stuck on the circular hole, so as to achieve the installation of the address encoder external chip. On the contrary, when disassembling, the air in the telescopic cylinder 104c is extracted to make the telescopic cylinder 104c retract, and the telescopic cylinder 104c is driven to be recovered through the hinge piece 104d, and then the arc-shaped rotary blade 104a is also driven to be recovered, and the rotary lock 104 is received in the receiving groove 104b, so as to complete the disassembly of the address encoder external chip.

[0051] By setting a rubber pad 104e on the upper surface of the arc-shaped rotor blade 104a, the rubber pad 104e is located in the part where the arc-shaped rotor blade 104a contacts the circular hole. On the one hand, this increases the friction between the arc-shaped rotor blade 104a and the circular hole, and on the other hand, it also reduces the vibration transmitted from the circular hole to avoid affecting the address encoder.

[0052] In this embodiment, when installing the external chip of the address encoder, first, a circular hole is opened in the outer shell of various existing belt conveyor comprehensive protection devices, and then the mounting seat 101b in the main body component 100 is inserted into the circular hole, and then the hand-held control rod 202f is pulled back and forth. Since one end of the control rod 202f is hinged to one of the pistons 202d, the piston 202d is driven to move back and forth in the corresponding air chamber 202b. An air suction hole 202c is provided at one end of the air chamber 202b. When the piston 202d is pulled, the piston 202d inhales air inside the air chamber 202b through the air suction hole 202c. When the piston 202d is pushed, the piston 202d in the air chamber 202b passes through the one-way air hole on the piston 202d, and guides it out. The piston 202d is fixed to the side of the belt 202e-2, and the other piston 202d is fixed to the other side of the belt 202e-2. The two pistons 202d are point-symmetrically arranged, so that the piston 202d drives the other piston 202d to move in the other air chamber 202b through the pulley 202e-1 and the belt 202e-2. Similarly, the other piston 202d reciprocates in the other air chamber 202b to inject air into the other side of the air cushion 201 from the air outlet 202g and the air inlet 201a on the other side of the air filling member 202, thereby realizing rapid air injection into the air cushion 201.

[0053] When the air cushion 201 is injected with air, the air cushion 201 is slowly filled so that the air cushion 201 fills the space between the circular hole and the flange 101c of the mounting seat 101b. At the same time, when the air cushion 201 is almost full, part of the air in the air cushion 201 will enter into each telescopic air cylinder 104c through the hose, extending the telescopic air cylinder 104c. Since the extended end of the telescopic air cylinder 104c is hinged to the free end of the arc-shaped rotary blade 104a through the hinge piece 104d, the free end of the arc-shaped rotary blade 104a is pushed to rotate and unfold around the hinge end, thereby clamping the arc-shaped rotary blade 104a on the inner side of the circular hole, locking the position of the mounting seat 101b on the outer shell of the belt conveyor comprehensive protection device, and continuing to inflate until the mounting seat 101b is completely installed in the circular hole and the circular hole is completely filled.

[0054] Then, the wires in the chip 102 are welded to the chip 102 in the belt conveyor integrated protection device to realize the circuit connection of the address encoder external chip. Finally, the housing of the belt conveyor integrated protection device is reinstalled on the belt conveyor integrated protection device to complete the installation of the address encoder chip 102 on the belt conveyor integrated protection device.

[0055] Finally, the control rod 202f is pulled out to make the piston 202d move away from the suction hole 202c, and the air chamber 202b is filled with gas, and then the control rod 202f is removed, and the insertion hole 201b is sealed with a plug, and then the gas filling part 202 is rotated 180 degrees, so that the left and right air chambers 202b exchange positions, so that the positions of the air inlet holes 201a corresponding to the two air chambers 202b are also completely exchanged. When the air cushion 201 is short of air, the two pistons 202d automatically move under the action of the pulley 202e-1 and the belt 202e-2, and replenish air into the air cushion 201 through the air inlet hole 201a, thereby achieving the effect of fully automatic air replenishment.

[0056] During dismantling, the gas filling part 202 is removed so that the air inlet hole 201a of the air cushion ring 201 is in contact with the outside world, thereby expelling the air in the air cushion ring 201 and the telescopic air cylinder 104c. The air in the telescopic air cylinder 104c is discharged, driving the arc-shaped rotor blade 104a to retract, thereby separating the mounting seat 101b from the circular hole, and the main component 100 is dismantled.

[0057] The remaining structures are the same as those of Example 1.

[0058] Example 3

[0059] Reference Fig. 9 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: a belt conveyor monitoring and control system, including a method for installing an external address encoder chip, and control components, including a host computer and an intelligent management station; various belt conveyor comprehensive protection devices, which are electrically connected to the control components, including multiple stretching switches, deviation switches, slip switches, tearing switches and coal blocking switches, each of which is equipped with an external address encoder chip.

[0060] The address encoder system is mainly composed of a main controller and multiple encoders required on site. They are connected to each other through RS-485 ports or internal wireless transmission units. The addresses of all encoders are unique. When working, the main controller sends the addresses of the encoders one by one. After receiving the addresses, the encoders compare them with the addresses set by themselves. Only encoders with the same addresses will respond. All external devices (address code deviation switches, address code pull rope switches, address code slippage and other address code devices) send the working status to the main controller. The main controller organizes and classifies the information according to the type of equipment, address code and content of the information. When a fault alarm occurs, the output relay alarm is output. At the same time, the main controller uploads the information to the host computer through another RS-485 port. The host computer can identify which address code terminal device issued the alarm information by accessing the information content, thereby determining its location, and realizing remote positioning and measurement of the positions and signals of all protection devices on site.

[0061] Reference Fig. 9 , Taking the pull-cord switch as an example, the installation position of the address encoder is determined by the location of the on-site protection device. An external address encoder chip can be installed on each set of pull-cord switches or other protection devices. In this design, we can use the RS-485 communication protocol, which has a long and stable communication distance or wireless transmission. And when the protection device fails or the equipment detects an operating failure, the relay alarm output can also be connected to the alarm unit such as the sound and light alarm to immediately issue an alarm message. System connection diagram, the master control station has two sets of terminals, one set is the output of the signal and relay, and the other two terminals are connected to the power supply.

[0062] Specifically, the system hardware consists of: the real-time monitoring and control system is composed of external equipment (pull rope, deviation, slip, tear, coal blockage) and other protection devices, address encoders, main controllers and computer terminals.

[0063] Connection and communication: All encoders are connected to the main controller via RS-485 port or wireless transmission unit, and the main controller sends the address of the encoder one by one. After receiving the address, the encoder compares it with the address set by itself, and only the encoder with the same address will generate a response. The external device sends the working status to the main controller, and the main controller organizes and classifies it according to the device type, address code and information content.

[0064] Offline fault judgment: When the external device cannot communicate with the main controller due to power failure, communication cable failure, etc., the device will automatically judge it as an offline fault. The relay outputs an alarm signal to indicate that there is an offline alarm.

[0065] Host computer identification and positioning: The host computer accesses the information content to identify which address code terminal device issued the alarm information, thereby determining the location of the faulty device. The host computer can remotely and accurately locate and measure the location and signals of all protection devices on site.

[0066] Repair and treatment: Once the faulty equipment is located, repair and treatment can be carried out in time to ensure the normal operation of the protection device.

[0067] The effective effects are (1) Real-time monitoring and control: The system can monitor external protection devices in real time and promptly detect equipment failures or operating fault information. (2) Alarm output: When a device fails or an operating fault is detected, the relay outputs an alarm signal to remind the operator to handle it. (3) Fault location: The system can accurately locate the location of the faulty equipment, allowing maintenance personnel to quickly and accurately locate and handle the fault. (4) Remote monitoring: The location and signals of all protection devices on site can be remotely monitored through the host computer, improving the work efficiency of operators. (5) Fault diagnosis: The system's information sorting and classification function can conduct comprehensive analysis and diagnosis of fault information, making it easier to determine the cause of the fault and formulate corresponding maintenance plans.

[0068] In short, the system realizes real-time monitoring, fault location and remote monitoring of multiple protection devices through the application of address encoder and the coordinated work with the main controller and host computer, further improving the safety and operation efficiency of the equipment.

[0069] To implement the design invention, first design the signal output circuit of the encoder device and conduct tests; reasonably design the position of the address encoder chip on the protection device along the coal conveyor belt and fix it firmly; make the RS-485 connection signal line or wireless transmission unit, where RS-485 can be made of shielded cables to prevent interference from AC signals; use the equipment maintenance opportunity to test the device, and continuously improve it according to the usage to perfect all functions. The present invention has a reasonable design and a simple structure. It can be implemented on the external (pull rope, deviation, slip, tear, coal blockage, etc.) protection device in the coal conveying system. The installation method is simple, the protection effect is good, the service life is long, and it is relatively stable, and the maintenance is more convenient. It protects the operation of the coal conveyor belt very well, prolongs the operating life of the equipment, and improves the operating reliability of the equipment. It can be widely used in similar equipment.
