[0053] In the present embodiment, for the case that the weight detection devices 11 are arranged on different working steel wire ropes 22 in the maintenance platform, each of the weight detection devices 11 can be arranged on the same position of the different working steel wire ropes 22.

[0054] In some embodiments of the present application, the digital display meter 12 is arranged on an electric control box of the maintenance platform 20.

[0055] In the present embodiment, the digital display meter 12 is installed on the electric control box, and the electric control box is installed on the maintenance platform 20. In this way, the display of the digital display meter 12 can be observed in real time, and the electric control box is controlled through the digital display meter 12, so as to control the movement of the maintenance platform.

[0056] One embodiment of the present application provides a maintenance platform 20, comprising:

[0057] a suspension platform 21;

[0058] a working steel wire rope 22 connected with the suspension platform 21, for driving the suspension platform 21;

[0059] a load weight digital display device 10 as described in the foregoing embodiments.

[0060] In this embodiment, the maintenance platform 20 is composed of a suspended platform 21, a working wire rope 22 and a load weight digital display device 10. The load weight digital display device 10 is used to monitor the weight data of the maintenance platform 20 in real time, and the working wire rope 22 is used to drive the suspended platform 21. When the weight of the maintenance platform 20 exceeds the limit, the working wire rope 22 stops driving the suspended platform 21, thereby avoiding the situation that the weight of the maintenance platform 20 exceeds the limit, eliminating the safety hazard and protecting the platform equipment and personnel safety.

[0061] In some embodiments of the present application, the maintenance platform 20 further comprises:

[0062] A power supply circuit for supplying power to the maintenance platform 20;

[0063] An electric control box, the electric control box comprising a protection circuit connected with the power supply circuit for controlling the on-off of the power supply circuit;

[0064] A microcontroller connected with the weight detection device 11 and the protection circuit respectively for obtaining the comparison result of the weight data and the weight threshold value and controlling the on-off of the protection circuit according to the comparison result.

[0065] In this embodiment, the power supply circuit can be the power supply system of the maintenance platform, which is responsible for providing the required electrical energy for the entire maintenance platform. The power supply circuit can be directly connected to the power grid, or it can be powered by a battery or other energy devices. The electric control box can be the electrical control center of the maintenance platform, which contains components for controlling and protecting the electrical system of the maintenance platform. The protection circuit inside the electric control box is an important part of it. The protection circuit can be a key part of the electric control box, which is connected with the power supply circuit, and its main function is to control the on-off of the power supply circuit to protect the maintenance platform from electrical faults or overload risks. The microcontroller can be the intelligent control unit of the maintenance platform or the electric control box, which is responsible for processing data from the weight detection device and controlling the protection circuit according to these data. The microcontroller determines whether the weight data exceeds the preset threshold value through program logic. The weight detection device 11 can be used to monitor the weight of the maintenance platform in real time and transmit the weight data to the microcontroller. The weight threshold value can be a preset weight value for comparison with the actual detected weight data. If the actual weight exceeds this threshold value, the microcontroller will take measures.

[0066] Exemplarily, when the maintenance platform is working, the weight detection device 11 continuously monitors the weight of the platform. The microcontroller receives the weight data transmitted by the weight detection device 11 and compares it with the preset weight threshold. If the monitored weight data exceeds the threshold, the microcontroller sends a signal to the protection circuit to disconnect the power supply circuit to prevent overload or other safety problems. If the weight data is within the safe range, the protection circuit keeps the power supply circuit energized, and the maintenance platform 20 can continue to work normally.

[0067] Exemplarily, the protection circuit diagram can be represented by Figure 3 , wherein all the logic of the protection circuit can be explained as follows:

[0068] 1. Press the start button S3, the coil KA1 is powered, KA1 is closed, KA6 coil is powered, KA6 is closed;

[0069] 2. Up 1: press the up button S6, the coils KA2 and KA3 are powered, X1Z, X1L, X2Z, and X2L start to control the left and right driver control signals;

[0070] 3. Up 2: press the right up button S8, the coil KA3 is powered, X2Z and X2L start to control the right driver control signal;

[0071] 4. Up 3: press the left up button S5, the coil KA2 is powered, X1Z and X1L start to control the left driver control signal;

[0072] 5. Down 1: press the down button S7, the coils KA4 and KA5 are powered, the normally open KA4 and KA5 are closed, the coils KA2 and KA3 lose power, the normally open KA2 and KA3 are restored, and X1Z and X2Z start to control the left and right driver control signals;

[0073] 6. Down 2: press the right down button S9, the coil KA5 is powered, and X2Z starts to control the right driver control signal;

[0074] 7. Down 3: press the left down button S4, the coil KA4 is powered, and X1Z starts to control the left driver control signal.

[0075] 8. After the weight detection device 11 collects the signal, the digital display instrument 12, i.e. the weight display table (K1, normally closed point), is provided with parameters (such as 1000 kg), and when the parameters are exceeded, K1 is disconnected, and the platform cannot be raised or operated.

[0076] 9. S1 and S2 are switches for emergency stop or stop, which are essential for the circuit.

[0077] The left and right ascension can be controlled separately, but the ascension and descension are simultaneous. S2 is a self-locking button (pushed down and not rebounded), and other buttons are self-resetting. Among them, Z is the start, L is the direction, Z and L give signals to the left and right drivers, and the operation of the battery hoist is controlled through the driver. In addition, the battery hoist has a default direction, and the default direction is descending, and the ascending direction needs to give a direction.

[0078] In some embodiments of the present application, the protection circuit comprises a first switch connected with the microcontroller, and the microcontroller is configured to control the on-off of the first switch according to the comparison result.

[0079] In the embodiment of the present application, first, the actual weight data of the maintenance platform 20 needs to be obtained through the weight detection device 11. This weight detection device 11 converts the weight into an electrical signal and then transmits it to the microcontroller. After receiving the signal of the weight sensor, the microcontroller converts the signal into weight data and compares it with the preset threshold value. According to the comparison result of the weight data and the threshold value, the next action is determined. Based on the comparison result, the microcontroller controls the first switch in the digital display instrument 12. This first switch is part of the protection circuit, and the function of the first switch is to protect the equipment from overload. If the detected weight data is greater than the preset threshold value, the first switch will disconnect the power supply circuit to prevent overload. If the detected weight data is less than the preset threshold value, the first switch will keep the power supply circuit powered on, allowing the equipment to work normally. The purpose of the above design is to protect the equipment from heavy load damage, and to achieve overload protection by automatically controlling the switch.

[0080] In some embodiments of the present application, the maintenance platform 20 further comprises:

[0081] A battery hoist is used to drive the working steel wire rope 22.

[0082] In the embodiment of the present application, the battery hoist can be a lifting device that uses batteries as a power source. Compared with traditional hoists, the battery hoist does not need to be connected to an external power source, so it has higher flexibility and portability. It can be used in places without fixed power supply, and is suitable for lifting operations that need to be moved or temporarily set up. The battery hoist is connected to the electric control box through a cable or other connection. The main function of the battery hoist is to lift or lower the load by driving the working steel wire rope 22. The working steel wire rope 22 is the medium connecting the hoist and the load, and it must be strong enough to bear the weight of the load and stable during lifting. The battery hoist tightens or loosens the working steel wire rope through the motor and transmission system, thereby realizing the movement of the load.
