Detailed implementation manners

[0026] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0028] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] As Figure 1 shown, a high-altitude equipment monitoring system includes a control unit 4, a power supply unit 12, an operating parameter detection unit, a deceleration and braking device 13, and a temperature reduction device 8 that are electrically connected to the control unit 4 respectively. The temperature reduction device 8 may include a fan.

[0030] The high-altitude equipment monitoring system of the present utility model further includes an electric control integrated box 11. The control unit 4 is arranged on the electric control integrated box 11. An analog input unit 5 is also arranged on the electric control integrated box 11. The analog input unit 5 is connected in series between the operating parameter detection unit and the control unit 4. The control unit 4 can be, but is not limited to, a PLC.

[0031] As Figure 1 shown, in the present utility model, the operating parameter detection unit is used to detect the operating parameters of the high-altitude equipment 15 and transmit the corresponding parameter signals to the control unit 4. In this embodiment, the operating parameter detection unit can include, but is not limited to, a rotational speed sensor 3 and a temperature sensor 2. The rotational speed sensor 3 and the temperature sensor 2 are installed on the high-altitude equipment 15 through a mounting bracket 1. Specifically, referring to Figures 2 to 11 , the temperature sensor 2 is installed on the mounting base 130 through the mounting bracket 1. The temperature sensor 2 is arranged close to the connecting shaft 151 to detect the temperature of the connecting shaft 151 and transmit the corresponding temperature signal to the control unit 4, so that the control unit 4 can monitor and control the high-altitude equipment 15 in real time according to the actual temperature of the connecting shaft 151, such as: deceleration and braking, high-temperature alarm, etc. Of course, the rotational speed sensor 3 can be installed on the output shaft of the high-altitude equipment motor to detect the rotational speed of the motor and transmit the rotational speed signal to the control unit 4, so that the control unit 4 can adjust the rotational speed of the motor or control the shutdown of the high-altitude equipment motor according to the actual rotational speed.

[0032] As Figures 2 to 11 collectively shown, the deceleration and braking device 13 of the present utility model is installed on the connecting shaft 151 between the high-altitude equipment 15 and the motor 150. The deceleration and braking device 13 includes a mounting base 130, a deceleration support base 132, a deceleration moving disk 137, a deceleration fixed disk 139, a friction plate 138, a reset member, a moving arm 135, a driving mechanism 131, a start-stop safety sensor 133, and a support adjustment assembly. Among them, the deceleration support base 132 is arranged on the upper surface of the mounting base 130.

[0033] As shown Figures 2 to 11 collectively, the reduction moving disk 137 and the reduction fixed disk 139 are buckled together. In this embodiment, the reduction moving disk 137 and the reduction fixed disk 139 are buckled together vertically. One side of the reduction moving disk 137 is hingedly connected to one side of the reduction fixed disk 139, specifically, it can be connected through a hinge 1301. The other side of the reduction fixed disk 139 is placed on the reduction support seat 132; wherein the friction plate 138 is arranged inside the reduction moving disk 137, and the connecting shaft 151 passes through between the friction plate 138 and the reduction fixed disk 139.

[0034] As shown Figures 2 to 11 collectively, the boom 135 of the present utility model is arranged vertically. One end of the boom 135 is connected to the driving mechanism 131. The other end of the boom 135 passes through the other side of the reduction moving disk 137, the reset member and the other side of the reduction fixed disk 139 in sequence and is limited to the reduction support seat 132. In a preferred solution, the reset member is a disc spring 136, and this disc spring 136 has the functions of buffering and resetting.

[0035] In this embodiment, the diameter of the boom 135 limited to the side of the reduction support seat 132 is smaller than the diameter of the other side. After the boom 135 is limited to the reduction support seat 132, it can move up and down, and at the same time maintain the connection relationship and positional relationship with the reduction moving disk 137, the disc spring 136 and the reduction fixed disk 139. In addition, the boom 135 can be limited by a retaining wall arranged inside the reduction support seat 132, or a limiting structure can be arranged at the end of the boom 135, and the limiting structure and the limiting cooperation structure on the reduction support seat 132 cooperate with each other to achieve limitation.

[0036] As shown Figures 2 to 11 collectively, the start-stop safety sensor 133 of the present utility model is electrically connected to the main power supply of the aerial equipment. The start-stop safety sensor 133 is used to detect the distance between the reduction moving disk 137 and the reduction support seat 132; specifically, the start-stop safety sensor 133 is installed on one side of the reduction moving disk 137 located at the reduction support seat 132. At the same time, a detection plate 1320 extending outward is arranged on the reduction support seat 132, and the detection plate 1320 is arranged opposite to the start-stop safety sensor 133 up and down. In this way, the start-stop safety sensor 133 accurately detects the distance between the reduction moving disk 137 and the reduction fixed disk 139 by detecting the distance from the detection plate 1320. That is, through this distance, it can be judged whether the reduction braking device 13 is in the reduction braking state. Once this distance is less than a preset limit value, it indicates that it is in the reduction braking state at this time, and then the start-stop safety sensor 133 transmits a corresponding electrical signal to the main power supply of the aerial equipment to forcibly cut off the power supply of the main power supply of the aerial equipment.

[0037] As shown Figures 2 to 11As shown together, the drive mechanism 131 of the present utility model includes a horizontally arranged control rod 1312 and a drive power component. One end of the control rod 1312 is hingedly connected to the drive power component, and the other end of the control rod 1312 is connected to one end of the boom 135. Specifically, the control rod 1312 and the boom 135 are connected by a pin shaft. In this embodiment, the drive power component includes a boom assembly 1310 provided on the mounting base 130 and a servo motor 1311 mounted on the boom assembly 1310. The output shaft of the servo motor 1311 is hingedly connected to one end of the control rod 1312. Specifically, a U-shaped mounting groove is provided at the other end of the control rod 1312, and the output shaft of the servo motor 1311 is arranged in the U-shaped mounting groove through a connecting rod and then hingedly connected through a hinge shaft.

[0038] The servo motor 1311 is electrically connected to the control unit 4. After the control unit 4 controls the servo motor 1311 to start, the output shaft of the servo motor 1311 drives one end of the control rod 1312 to rotate, causing the other end of the control rod 1312 to press down, thereby driving the boom 135 to move downward, causing the deceleration moving disk 137 and the friction plate 138 inside it to move downward, and finally causing the friction plate 138 to contact the connecting shaft 151 to achieve deceleration through friction. After the deceleration moving disk 137 moves downward, it drives the start-stop safety sensor 133 to move downward, causing it to detect that the distance from the detection plate 1320 becomes smaller. When the distance is less than the limit value, the start-stop safety sensor 133 transmits a corresponding electrical signal to the main power supply of the aerial equipment, causing the main power supply of the aerial equipment to be forcibly powered off to achieve deceleration and braking.

[0039] As Figures 2 to 11 As shown together, the deceleration braking device 13 of the present utility model further includes a support adjustment assembly. The support adjustment assembly includes a vertically arranged support adjustment arm 134 and a support adjustment base 1300. The top end of the support adjustment arm 134 is connected to the control rod 1312, and the bottom end of the support adjustment arm 134 is threadedly connected to the support adjustment base 1300. Moreover, the bottom end of the support adjustment arm 134 passes through the support adjustment base 1300 and is connected to an adjustment nut 1340, and the adjustment nut 1340 is a manual rotating wheel. To prevent the safety gap between the friction plate 138 and the connecting shaft 151 from becoming larger due to the wear of the friction plate 138 during use over time and the deceleration braking function decreasing, the vertical height can be adjusted through the manual rotating wheel at the lower end of the support adjustment arm 134, thereby driving the control rod 1312 and the boom 135 to adjust the vertical gap of the deceleration moving disk 137 connected thereto, thus ensuring the stability of the deceleration braking device 13 during use.

[0040] As Figure 1 As shown, the electric control integrated box 11 of the present utility model is further provided with an alarm unit 10 and a display unit. The alarm unit 10 and the display unit are respectively electrically connected to the control unit 4. The alarm unit 10 can be an audible and visual alarm unit 10, and the display unit can include a touch screen display 7.

[0041] As Figures 1 to 11 Figures 1 to 11 As commonly shown, when the high-altitude equipment monitoring system of the present utility model is actually used, the temperature sensor 2 and the rotational speed sensor 3 are installed at corresponding positions on the high-altitude equipment 15 through the mounting bracket 1. For example, the temperature sensor 2 is installed around the connecting shaft 151 to accurately detect the temperature of the connecting shaft 151, and the rotational speed sensor 3 is installed on the output shaft of the motor to accurately detect the rotational speed of the motor.

[0042] The temperature signal detected by the temperature sensor 2 and the rotational speed signal detected by the rotational speed sensor 3 are respectively transmitted to the control unit 4 through the analog input unit 5.

[0043] After receiving the temperature signal and the rotational speed signal, the control unit 4 converts them into display signals, and then transmits them to the touch display screen 7 through the analog output unit 6. The touch display screen 7 then displays the temperature and rotational speed of the corresponding high-altitude equipment 15 for the staff to monitor in real time. At the same time, the control unit 4 compares the temperature signal and the rotational speed signal with the preset threshold values. When the temperature signal and / or the rotational speed signal exceeds the alarm threshold, the control unit 4 triggers the alarm unit 10 to issue a warning, so that the staff can check and handle it in time, thus avoiding the expansion of the fault.

[0044] Similarly, when the temperature signal is greater than the preset braking stop threshold, the control unit 4 controls the servo motor 1311 of the deceleration braking stop device 13 to start, to decelerate and brake the connecting shaft 151 between the high-altitude equipment 15 and the motor 150, and at the same time forcibly cut off the main power supply of the high-altitude equipment to achieve deceleration and braking stop. Or, when the temperature signal is greater than the preset high-temperature threshold, the control unit 4 starts the cooling device 8 to forcibly cool down and ensure the integrity of the equipment to prevent high-temperature danger.

[0045] It can be seen that the present utility model monitors the operating parameters of the high-altitude equipment 15 in real time through the operating parameter detection unit, without the need for personnel to climb to a high altitude for detection. When the parameter signal appears abnormal and exceeds the range, an alarm is triggered to prompt the operator. When the collected parameter signal reaches the preset shutdown threshold, the control unit 4 controls the high-altitude equipment 15 to shut down, and starts the cooling device 8 or the deceleration braking stop device 13 according to the abnormality of the parameter signal to ensure the safe and effective operation of the equipment.

[0046] The present utility model realizes the effective real-time monitoring of the parameters (temperature, rotational speed) of the high-altitude platform equipment. The operator can view the operating parameters of the equipment in real time through the touch display screen 7 on the electric control integrated box 11. The operator no longer has the problem of climbing the high-altitude platform to view and record the equipment parameters as before, solves the drawback that the equipment parameters cannot be effectively and real-time controlled, and improves the operation efficiency on the premise of ensuring the operation safety of the operator.

[0047] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent improvement of a high-altitude equipment monitoring system, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
