Example two

As shown in fig. 6, the present embodiment provides a method for controlling a lifting device for maintaining a high-voltage transmission line, which is applied to the lifting device for maintaining a high-voltage transmission line provided in the first embodiment, and the method mainly includes:

starting the lifting device, and judging whether the lifting device can enter a working mode;

if the lifting device can enter the working mode, the driving power of the driving piece 5 is matched, and the running speed of the lifting device is determined;

the lifting device operates in a working mode;

judging whether the lifting device has an operation fault or not, and if so, judging whether the lifting device can enter a safety mode or not;

and if the lifting device cannot enter the safety mode, stopping the operation of the lifting device, and entering a manual operation mode.

According to the control method of the lifting device for maintaining the high-voltage transmission line, whether the lifting device has an operation fault or not is detected in real time in the lifting process of the lifting device, so that the operation safety of maintenance personnel is ensured, the safety factor of the operation of the maintenance personnel is improved, and the labor intensity of the maintenance personnel is reduced.

Fig. 7 is a flowchart illustrating detailed steps of a control method of a lifting device for maintaining a high-voltage transmission line according to this embodiment, and the control method according to this embodiment is described in detail below with reference to fig. 7.

The control method of the lifting device for maintaining the high-voltage transmission line comprises the following steps:

step one, the lifting device is started to obtain the weight borne by the body 1, the residual electric quantity of the power supply 6 and the wind speed at the upper part of the tower to be maintained.

In this embodiment, the weight borne by the body 1 is obtained through the weighing sensor, the remaining electric quantity of the power supply source 6 is obtained through the power management module, and the wind speed sensor arranged on the upper portion of the maintenance tower transmits the collected wind speed signal to the controller 7.

And step two, determining whether the lifting device can enter a working mode according to the weight borne by the body 1, the residual electric quantity of the power supply 6 and the wind speed.

In order to ensure the safety of the maintenance work when the weight carried by the body 1 exceeds a preset weight value, the operation of the lifting device is not allowed in this case. If the weight that body 1 bore meets the demands, then need detect whether power supply 6 remaining electric quantity can satisfy the operation demand once, avoid the operation midway electric quantity not enough and influence the maintenance operation. If the lifting device meets the operation requirement, whether the wind speed value acquired by the wind speed sensor arranged at the upper part of the maintenance tower is smaller than a preset wind speed value is judged, and if so, the lifting device can operate to ensure the safety of maintenance personnel.

And step three, if the lifting device can enter the working mode, matching the driving power of the driving piece 5 and determining the running speed of the lifting device.

In this embodiment, if the lifting device can operate, the working mode can be entered, that is, the driving member 5 drives the first transmission assembly and the second transmission assembly, and then drives the winding wheel 4 to rotate to wind or unwind the rope, so as to realize ascending or descending.

Before the driving member 5 is started, the driving power of the driving member 5 needs to be matched according to actual conditions, and the running speed of the lifting device is determined. In this embodiment, the driving power of the driving member 5 is matched according to the weight carried by the body 1 and the remaining amount of power of the power supply 6, and transmitted to the controller 7 to control the driving member 5. And determining the running speed of the lifting device according to the wind speed on the tower to be maintained so as to provide the optimal running mode.

And step four, operating the lifting device in a working mode.

And step five, judging whether the lifting device has an operation fault, and if so, judging whether the lifting device can enter a safety mode.

In this embodiment, the operation failure includes at least one of an inclination angle of the elevating device being greater than a preset angle, an acceleration of elevation of the elevating device being greater than a preset acceleration, occurrence of a high voltage corona above the elevating device, and an electrical failure. The operation failure may also include other failures that may cause the lifting device to fail to operate normally due to external factors, and is not particularly limited herein.

Specifically, if the inclination angle of the lifting device is greater than the preset angle, it indicates that the seat is inclined, or the acceleration of the lifting device is suddenly greater than the preset acceleration in the lifting process, or the high-voltage corona occurs above the lifting device in the lifting process, or some electrical faults occur in the lifting device itself, such as power supply alarm, running program error, and the like, and the above situations all affect the operation safety of maintenance personnel.

In this embodiment, in the safety mode, the lifting device is lowered to the ground at a preset speed. Generally, the preset speed value is smaller so as to ensure that maintenance personnel can safely land on the ground. In some of the above-mentioned faults, some situations are suitable for entering the safe mode, and some situations are not suitable for entering the safe mode, so after the operation fault is determined, the type of the fault needs to be determined to judge whether the lifting device is suitable for entering the safe mode.

Exemplarily, when a high-voltage corona occurs above the lifting device in the lifting process or some electrical faults occur in the lifting device, the lifting device enters a safety mode, so that maintenance personnel can descend to the ground to ensure safety.

When the lifting device is inclined or the acceleration of the lifting device is suddenly higher than the preset acceleration in the lifting process, the lifting device cannot enter the safety mode.

And step six, if the lifting device cannot enter the safety mode, stopping the operation of the lifting device, and entering a manual operation mode.

When the lifting device inclines or the acceleration of the lifting device is suddenly higher than the preset acceleration in the lifting process, if the lifting device still continues to operate, the personal safety of maintenance personnel can be threatened. In the above case, the operation of the lifting device needs to be stopped, and a manual operation mode needs to be entered.

And seventhly, judging whether the potential safety hazard is eliminated or not in a manual operation mode.

Step eight, if the potential safety hazard is eliminated, manually unlocking, and continuously operating the lifting device; if the potential safety hazard is not eliminated, the manual rotating wheel 8 is manually operated, and the lifting device is lowered to the ground.

Specifically, after the maintenance personnel select the manual operation mode, the lifting device automatically judges whether the potential safety hazard is eliminated, if so, the lifting device can continue to operate, and if not, the maintenance personnel can manually operate the manual rotating wheel 8 according to personal requirements to enable the lifting device to descend to the ground so as to ensure the operation safety.

Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
