Description

Technical Field

[0001] This utility model relates to the field of cableway equipment monitoring technology, and specifically to a cableway trolley tire pressure monitoring system. Background Technology

[0002] Single-line circulating detachable cableways have a large carrying capacity, numerous cabins, and high operating speeds. Within the station, they can slow down to facilitate passenger boarding and alighting. Achieving high speed and high capacity places high demands on the tire pressure of the station's trolley system. This is because after the cabins enter the station, they need to pass through detachment zones, deceleration zones, turning zones, acceleration zones, and engagement zones using the station's trolley tires. The pressure on the trolley tires varies in different areas, resulting in uneven wear.

[0003] Each station of the detachable cableway has approximately 100 trolley tires. Every day after operation, all trolley wheels in the station must undergo an evening inspection. Inspection methods include: Method 1: tapping the trolley wheels with a hammer; Method 2: checking tire pressure with a tire pressure gauge. Both methods are time-consuming and labor-intensive, and tire pressure cannot be monitored in real-time during equipment operation.

[0004] In view of this, it is very urgent to develop and apply a cableway trolley tire pressure monitoring system. Utility Model Content

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] See Figure 1-6 As shown, a cableway trolley tire pressure monitoring system includes: multiple external tire pressure monitors 1, repeaters 2, a tablet computer 3, and several Bluetooth modules 4.

[0025] Each of the external tire pressure monitoring devices 1 is installed on the conversion valve interface on the outside of the tire 101 of the cableway trolley wheel; each tire 101 of the cableway trolley wheel has an independent and unique code; the repeater 2 is set inside the carriage, and each external tire pressure monitoring device 1 transmits tire pressure information to the repeater 2 via microwave communication, and the repeater 2 collects and summarizes the tire pressure information of each tire 101; the tablet computer 3 is set inside the carriage and is used to display the real-time tire pressure data of the tire 101 of the trolley wheel; the Bluetooth module 4 is installed inside the carriage and is used to establish communication between the repeater 2 and the tablet computer 3, so that the repeater 2 and the tablet computer 3 are electrically connected to transmit the collected tire pressure information to the tablet computer 3, and the tablet computer 3 is used to set the tire pressure range. If the tire pressure exceeds the set value, a tire position information alarm will be triggered.

[0026] When this utility model cableway trolley tire pressure monitoring system is working, the external tire pressure monitor 1, installed on the valve port of the tire 101 of each cableway trolley wheel, monitors the tire pressure. The data is then transmitted to the repeater 2 via microwave. The repeater 2 collects and summarizes the tire pressure information of each tire 101 and transmits it to the tablet computer 3.

When an alarm occurs, it can directly display the fault location, accurately identify which tire has abnormal pressure, and thus solve the problem in a timely manner, keeping the tire pressure within the correct range. This greatly improves the efficiency of tire pressure monitoring, saves manual measurement costs, and reduces workload. At the same time, it can reduce tire wear and prevent tire blowouts and flat tires that may be caused by excessive or insufficient pressure. This effectively reduces the tire blowout rate, increases tire life, saves fuel, saves tire procurement costs, better ensures the safe operation of the equipment, and, most importantly, reduces many safety hazards caused by tire blowouts.

[0027] The structure of the external tire pressure monitoring device 1 will be explained in detail below.

[0028] The external tire pressure monitoring device 1 includes a main housing 11, a PCB board 12 installed inside the main housing 11, a wireless transmission module disposed on the PCB board 12, a pressure sensor 13 for detecting pressure, an air valve assembly 14 inserted into the main housing 11, a button battery 15 disposed on the PCB board 12 and supplying power to the PCB board 12, a first metal plate 16 and a second metal plate 17 disposed on the PCB board 12 and electrically connected to the two electrodes of the button battery 15, a cover plate 18 detachably and sealed on the main housing 11 and covering the button battery 15, and a base plate 19 detachably and sealed at the lower end of the main housing 11 and covering the PCB board 12. The air valve assembly 14 has a connection with the pressure sensor. The air valve assembly 14 has a valve cap screw-sealed at one end and an internal thread 142 and a valve needle 143 at the other end. The internal thread 142 screws the valve valve assembly 14 to the external valve adapter interface of the tire 101. The valve needle 143 presses against the valve adapter interface to open it, allowing air from the tire to enter the air valve assembly 14. The air then passes through the air valve assembly 14's air hole 141 and acts on the pressure sensor 13, causing the pressure sensor 13 to detect the tire pressure. This achieves the purpose of monitoring tire pressure. The tire pressure information is transmitted via a wireless transmission module on the PCB board 12, and the repeater 2 receives and processes the data. The external tire pressure monitor 1 directly mounts a first metal plate 16 and a second metal plate 17 on the PCB board 12, and these plates are electrically connected to the two electrodes of the button battery 15, providing power to the button battery 15. Its structure is extremely simple. The purpose of the mounting base plate 19 of the external tire pressure monitor 1 is to better install the PCB board 12, while the purpose of the mounting cover plate 18 of the external tire pressure monitor 1 is to better install and replace the button battery 15. The cover plate 18 also presses against the button battery 15, so that the button battery 15 is stably installed in the main housing 11 and forms a stable electrical connection with the first metal plate 16 and the second metal plate 17.

[0029] A sealing gasket 144 is also provided around the valve needle 143. The sealing gasket 144 around the valve needle 143 presses against the valve stem interface to achieve a sealed contact and prevent air leakage.

[0030] In some embodiments, the cover plate 18 is provided with a tool slot 181 for tools to pass through, which facilitates the installation and removal of the cover plate 18 relative to the main housing 11.

[0031] In some embodiments, a battery slot 111 is provided at the upper end of the main housing 11, and the first metal sheet 16 and the second metal sheet 17 are both exposed in the battery slot 111. After the button battery 15 is pressed into the battery slot 111, it simultaneously contacts the first metal sheet 16 and the second metal sheet 17. The first metal sheet 16 is T-shaped and includes a first main body 161 and a first elastic contact 162 and a second elastic contact 163 bent and formed at the upper end of the first main body 161. The lower end of the first main body 161 is inserted into the PCB board 12 and soldered to fix it, which is easy to assemble. The first elastic contact 162 and the second elastic contact 163 simultaneously wrap around the button battery 15 to contact one electrode of the button battery 15, forming a double-point contact to ensure the stability of the conduction. The second metal sheet 17 is inverted L-shaped and includes a second main body 171 and a third elastic contact 172 bent at the upper end. The lower end of the second main body 171 is inserted into the PCB board 12 and soldered to fix it, which makes assembly easy. The third elastic contact 172 contacts the lower end face of the button battery 15 to contact the other electrode of the button battery 15. It is a press contact and has good conductive stability.

[0032] The assembly structure of the main housing 11 and the cover plate 18 is as follows: the upper end of the main housing 11 is provided with a first groove 112 facing downwards. The first groove 112 is distributed around the battery compartment 111 and is not connected. One inner wall of the first groove 112 is provided with a thread. The lower end of the cover plate 18 is provided with an external threaded protrusion ring 182. The external threaded protrusion ring 182 is screwed into the first groove 112 and is screwed and fixed with the thread inside the first groove 112. The external threaded protrusion ring 182 is placed around the battery compartment 111, which can achieve a more sealed and more stable assembly.

[0033] To facilitate the removal of the button battery 15, the following design was also made: a clearance opening 113 is provided at the bottom of one side of the battery slot 111. When the button battery 15 is pressed near the clearance opening 113, one side of the button battery 15 is partially pressed into the clearance opening 113, and the other side of the button battery 15 is raised to protrude out of the battery slot 111. At this time, it is easy to remove the button battery 15, and the operation is extremely convenient.

[0034] The photographic structure of the main housing 11, PCB board 12, and base plate 19 is as follows: The lower inner wall of the main housing 11 is provided with a mounting groove 114, and a plurality of first screw post 115 are provided within the mounting groove 114. Two second screw post 116 are integrally formed on the inner wall of the mounting groove 114. The PCB board 12 is provided with a positioning groove 121 that matches the second screw post 116. After the PCB board 12 is inserted into the mounting groove 114, it presses against the first screw post 115. The positioning groove 121 on the periphery of the PCB board 12 is aligned with the outer surface of the second screw post 116. The PCB board 12 is locked in the positioning groove 121 by a first screw that passes through the first through hole 122 and is screwed into the first screw post 115. The assembly structure is extremely stable. The second screw passes through the first countersunk hole 191 on the base plate 19 and is screwed into the second screw post 116. The lower opening of the main housing 11 is provided with an annular groove 117, and the upper outer periphery of the base plate 19 is provided with an annular flange 192. The annular flange 192 and the annular groove 117 are locked in place, which not only achieves positioning but also improves sealing performance.

[0035] The outer side of the housing 41 of the Bluetooth module 4 is provided with two lugs 411, each lug 411 having a connection hole 412. During installation, a strap can be passed through the connection hole 412 of the lug 411 to connect to an external object, or a screw can be passed through the connection hole 412 of the lug 411 to screw and fix to the external object. Both methods can achieve the purpose of convenient installation.

[0036] The repeater 2 has a built-in GPRS module and can communicate with the backend server 5 through the GPRS module to store tire status information in the database of the backend server, which can be queried and managed via mobile phone or computer; or, the tablet computer 3 has a built-in wireless communication module and can communicate with the backend server through the wireless communication module to store tire status information in the database of the backend server 4, which can be queried and managed via mobile phone or computer.

[0037] The tablet computer 3 has a U-shaped area that displays the coding information and tire pressure information of all cableway trolley wheels' tires 101. The tablet computer 3 also has a magnified information display area, which is used to display the coding information of a specific cableway trolley wheel's tire 101 when clicked. The magnified information display area displays the coding information and tire pressure information of the cableway trolley wheel's tire 101 after being magnified several times. If the tire 101 of the cableway trolley wheel is low or otherwise hidden, a red background is displayed to realize a color alarm. This achieves a visual display of the tire pressure of each cableway trolley wheel's tires. When an alarm occurs, the fault location can be directly displayed to accurately identify which tire has abnormal tire pressure, so that the problem can be solved in time and the tire pressure can be kept within the correct range.

[0038] In summary, when the cableway trolley tire pressure monitoring system of this utility model is working, the external tire pressure monitor 1 installed on the valve port of the tire 101 of each cableway trolley wheel monitors the tire pressure. The data is then transmitted to the repeater 2 via microwave. The repeater 2 collects and summarizes the tire pressure information of each tire 101 and transmits it to the tablet computer 3. The tablet computer 3 sets the tire pressure range. If the tire pressure exceeds the set value, a tire position information alarm will be triggered, so that the problem can be solved in time and the tire pressure can be kept within the correct range. This greatly improves the efficiency of tire pressure monitoring, saves manual measurement costs, and reduces workload. At the same time, it can reduce tire wear and prevent tire blowouts and flat tires that may be caused by excessive or insufficient pressure. This effectively reduces the tire blowout rate, increases tire life and saves fuel and tire procurement costs, better ensures the safe operation of the equipment, and, more importantly, reduces many safety hazards caused by tire blowouts.
