DETAILED DESCRIPTION

[0026] Please refer to Figures 1-6 ​​The utility model provides a technical scheme: a tail rope winding and unwinding machine double power supply switching device, including device bottom plate 1, double power supply detection switching control mechanism 2, tail rope winding and unwinding mechanism 3 and leakage safety protection device 4, double power supply detection switching control mechanism 2 fixedly connected in the top of device bottom plate 1, tail rope winding and unwinding mechanism 3 fixedly connected in the top of double power supply detection switching control mechanism 2, leakage safety protection device 4 fixedly connected the bottom of double power supply detection switching control mechanism 2.

[0027] The specific settings and functions of the double power supply detection switching control mechanism 2, the tail rope winding and unwinding mechanism 3 and the leakage safety protection device 4 will be described below.

[0028] In the embodiment: double power supply detection switching control mechanism 2 includes spare power supply 21 fixedly connected to one side of the top of device bottom plate 1, the outer surface of spare power supply 21 is fixedly connected with connecting line 22, the distal end of connecting line 22 is fixedly connected with power supply switching control assembly 23, the inside of power supply switching control assembly 23 is fixedly connected with fixed assembly 24 at the connecting place of connecting line 22, the outer surface of connecting line 22 is clamped with protection positioning plate 25, and protection positioning plate 25 is fixedly connected to the outer surface of device bottom plate 1.

[0029] The above components achieve the following effects: protection positioning plate 25 firmly clamps connecting line 22 in a specific position through the precisely designed clamping groove or buckle structure, prevents connecting line 22 from shaking and winding randomly during device operation, avoids wear, short circuit and other faults caused by line winding, and guarantees the normal service life of the line

[0030] Specifically, power supply switching control assembly 23 includes intelligent detection controller 231 fixedly connected to the outer surface of connecting line 22, power supply switch 232 fixedly connected to one side in the inside of intelligent detection controller 231, commonly used power supply 233 fixedly connected to the outer surface of intelligent detection controller 231, servo motor 234 fixedly connected to the other side in the inside of intelligent detection controller 231, and the output end of servo motor 234 is fixedly connected to the outer surface of tail rope winding and unwinding mechanism 3.

[0031] The above components achieve the following effects: once commonly used power supply 233 appears fault conditions such as overvoltage, undervoltage, open phase or abnormal current, intelligent detection controller 231 can capture abnormal signals in a very short time and quickly issues instructions to power supply switch 232, power supply switch 232 seamlessly cuts off the connection of commonly used power supply 233 and quickly connects spare power supply 21, ensures the continuous and stable power supply of tail rope winding and unwinding machine, enables it to run uninterruptedly, and avoids construction interruption caused by power supply failure.

[0032] Specifically, the fixing assembly 24 comprises a rubber sealing ring 241 fixedly connected to the outer surface of the intelligent detection controller 231, and a connecting clamp 242 is clamped to the outer surface of the rubber sealing ring 241.

[0033] The above-mentioned components achieve the effect that the rubber sealing ring 241 is soft and has good sealing performance, tightly fits the connection between the intelligent detection controller 231 and the connecting wire 22, forms a strict protective barrier, and effectively prevents external impurities such as dust, water vapor, and oil stains from invading the connection part.

[0034] Specifically, the tail rope winding and unwinding mechanism 3 comprises a support frame 31 fixedly connected to the top of the device base plate 1, and limit bolts 32 are threadedly connected to the two sides of the support frame 31. The support frame 31 is threadedly connected to the top of the device base plate 1 through the limit bolts 32, and the support frame 31 and the limit bolts 32 are symmetrically arranged on the top of the device base plate 1.

[0035] The above-mentioned components achieve the effect that the symmetrically arranged support frame 31 and limit bolts 32 provide a stable support structure for the entire tail rope winding and unwinding mechanism 3. By rotating the limit bolts 32, the support frame 31 is fixed, which can effectively resist external forces generated during the winding and unwinding of the tail rope, ensure the stability of the rotating parts during operation, and avoid problems such as shaking and deviation caused by unstable support.

[0036] Specifically, one side of the support frame 31 is fixedly connected to the outer surface of the dual-power detection and switching control mechanism 2, and the tail rope winding and unwinding mechanism 3 comprises a rotator 33 fixedly connected to the output end of the servo motor 234, and a rotating connection shaft 34 is fixedly connected to the outer surface of the rotator 33.

[0037] The above-mentioned components achieve the effect that the torque output by the servo motor 234 can be efficiently transmitted to the rotator 33 and the rotating connection shaft 34, and the rotating connection shaft 34 is driven to rotate synchronously.

[0038] Specifically, the outer surface of the rotating connection shaft 34 is rotatably connected to a bearing 35, the outer surface of the bearing 35 is rotatably connected to the outer surfaces of the symmetrically arranged support frames 31, and the outer surface of the bearing 35 is embedded in the interior of the support frame 31.

[0039] The above-mentioned components achieve the effect that the bearing 35 reduces the friction between the rotating connection shaft 34 and the support frame 31 when the rotating connection shaft 34 rotates, effectively improves the rotating efficiency, reduces energy loss, and significantly prolongs the service life of the rotating connection shaft 34 and the support frame 31.

[0040] Specifically, the electric leakage safety protection device 4 comprises an electric leakage detector 41 fixedly connected to the other side of the top of the device bottom plate 1, and a control switch 42 rotatably connected to the outer surface of the electric leakage detector 41, and the outer surface of the control switch 42 is fixedly connected to the bottom of the dual power supply detection and switching control mechanism 2 through the connecting line 22.

[0041] The electric leakage detector 41 can monitor the electric leakage of the circuit in real time, and the control switch 42 can cut off the power supply as soon as an abnormality is found, thereby providing all-round and reliable protection for the personal safety and equipment safety of the operator.

[0042] Working principle: when the device is normally operated, the intelligent detection controller 231 continuously monitors various parameters of the normal power supply 233, and the standby power supply 21 is in a hot standby state and is ready to be put into use at any time. The servo motor 234 is controlled by the intelligent detection controller 231 to output corresponding power according to the construction requirement, drive the rotator 33 and the rotating shaft 34 to rotate, and realize the winding and unwinding operation of the tail rope. In this process, the electric leakage detector 41 monitors the electric leakage of the circuit in real time.

[0043] As soon as the intelligent detection controller 231 detects a failure of the normal power supply 233, it sends a switching instruction to the power supply switch 232, and the power supply switch 232 quickly acts to cut off the normal power supply 233 and connect the standby power supply 21, so as to ensure the power supply of the servo motor 234 and the tail rope winding and unwinding mechanism 3 is not affected, and the construction can continue.

[0044] If the electric leakage detector 41 detects an electric leakage signal, it immediately transmits the signal to the control switch 42, and the control switch 42 quickly cuts off the power supply and stops the operation of the entire device to prevent the expansion of the electric leakage accident. After the fault is eliminated, the operator can manually reset the control switch 42 to restart the device and restore the normal working state. In the whole working process, the components work closely together to realize the efficient and reliable operation of the dual power supply switching and electric leakage safety protection of the tail rope winding and unwinding mechanism, and comprehensively improve the safety and stability of the electric power construction.
