Description

Technical Field

[0001] The invention relates to the technical field of circuit maintenance equipment, and in particular to an automatic lifting device for an anti-winding bypass cable. Background Art

[0002] In the field of circuit maintenance equipment technology, especially in the non-stop inspection and maintenance of bypass cables, the lifting operation of bypass cables has always been an important and challenging task. Traditional bypass cable lifting devices usually adopt a relatively simple structure and operation method, and mainly rely on manual operation of operators to lift and lower bypass cables. However, this traditional method has many problems. On the one hand, in the process of lowering heavy objects on the bypass cable, due to the lack of effective anti-entanglement design, the insulating rope is very easy to get entangled. The winding of insulating ropes will have many negative effects on the operation. First of all, it will greatly interfere with the operation process and make the operation difficult. Operators need to spend a lot of time and energy to solve the winding problem, resulting in a significant increase in operation time, thereby causing a waste of labor costs. For example, when the insulating rope is entangled, the operator may need to suspend the operation and manually comb the entangled rope, which not only prolongs the time for inspection and maintenance, but also may affect the overall work schedule.

[0003] On the other hand, the winding of insulating ropes will make the operation process unstable and unpredictable, increasing the uncertainty of the operation. It is difficult for operators to accurately control the speed and position of the bypass cable, which will affect the subsequent inspection and maintenance work. Moreover, this uncertainty may lead to a series of potential dangers, such as uneven force on the insulating rope due to winding, which may cause the rope to break or other parts to be damaged, thus posing a threat to the safety of operators and surrounding equipment.

[0004] To this end, we propose an anti-entanglement bypass cable automatic lifting device to solve the above problems. Summary of the invention

A cylindrical reversing gear is installed on the reversing shaft, and the cylindrical reversing gear is meshed with the winding drum gear. A wire puller gear and a first insulating rope tensioning wheel are installed on the first tensioning wheel shaft, and the wire puller gear is meshed with the cylindrical reversing gear. A second insulating rope tensioning wheel is installed on the second tensioning wheel shaft.

[0013] In the above-mentioned anti-entanglement bypass cable automatic lifting device, the first mounting side plate and the second mounting side plate are both provided with a first mounting groove, a second mounting groove, a third mounting groove, a fourth mounting groove and a fifth mounting groove, a thrust needle roller combination bearing is installed in each of the first mounting grooves, and the reduction gear is installed on the outside of one of the thrust needle roller combination bearings, and the winding drum is installed on the other thrust needle roller combination bearing.

[0014] In the above-mentioned anti-entanglement bypass cable automatic lifting device, a deep groove ball bearing is provided in the second mounting groove on the first mounting side plate, and the driving gear is installed on the outside of the deep groove ball bearing.

[0015] In the above-mentioned anti-entanglement bypass cable automatic lifting device, flange bearing one is installed in each of the two third mounting grooves, and the reversing shaft is installed on the two flange bearings one, flange bearing two is installed in each of the two fourth mounting grooves, and the first tensioning wheel shaft is installed on the two flange bearings two.

[0016] In the above-mentioned anti-winding bypass cable automatic lifting device, a flange bearing three is installed inside each of the fifth mounting grooves, and the second tensioning wheel shaft is installed on two flange bearings three.

[0017] In the above-mentioned anti-entanglement bypass cable automatic lifting device, the ratio of the number of teeth of the winding drum gear to the number of teeth of the wire puller gear is 11:1.

[0018] In the above-mentioned anti-winding bypass cable automatic lifting device, the cylindrical reversing gear is fixed on the reversing shaft by a nut and a retaining ring.

[0019] In the above-mentioned anti-entanglement bypass cable automatic lifting device, an insulating rope is installed on the winding drum, and the end of the insulating telescopic wire away from the winding drum passes through the first insulating rope tensioning wheel and the second insulating rope tensioning wheel, the inside of the eddy current sensor bracket and extends downward.

[0020] In the above-mentioned anti-entanglement bypass cable automatic lifting device, the first insulating rope tensioner is tangent to the surface of the second insulating rope tensioner, and the first insulating rope tensioner and the second insulating rope tensioner are both provided with internal tooth grooves, and the inlet and outlet of the insulating rope are located at the internal tooth groove opening between the first insulating rope tensioner and the second insulating rope tensioner.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Keep it in a tensioned state during the lowering process. The traditional bypass cable lifting device lacks such a design, so the insulating rope is easy to get tangled when it is lowered. This device effectively avoids this problem, thereby improving the smoothness and safety of the operation, reducing equipment failures and maintenance costs caused by rope entanglement, solving the problem of insulating rope entanglement, reducing the time and labor waste of operators manually lifting bypass cables, and reducing the uncertainty and danger of the operation. Since the insulating rope is avoided from being entangled, the risk of short circuits and other safety hazards caused by rope entanglement is reduced, and the possible injuries to operators during the operation are also reduced, providing a safer operating environment for circuit maintenance personnel in non-stop inspection and maintenance of bypass cables.

[0023] 2. The remote control operation mode can be used to start the motor through the remote control and the circuit board control system, thereby controlling the operation of the entire device. This remote control operation mode is convenient and fast. The operator does not need to directly operate the device manually, which reduces the difficulty and risk of operation. It allows a single person to complete the lifting and lowering of the bypass cable, greatly improving the convenience of operation. For some bypass cable inspection and maintenance operations that need to be carried out at high places or in complex environments, the operator can control the device in a relatively safe position, improving work efficiency.

[0024] 3. Equipped with an eddy current sensor bracket. The insulating rope will pass through the inside of the eddy current sensor bracket during the ascent or descent process. The eddy current sensor can accurately sense the position of the insulating rope and provide real-time feedback to the system. Through the system processing of this information, the lifting height of the bypass cable can be accurately controlled to ensure that the bypass cable can be accurately lifted to the set height, avoiding operational errors or equipment damage caused by inaccurate height control, and improving the accuracy of the operation.

[0025] 4. The device uses multiple mounting side plates, and various bearings (such as thrust needle roller combination bearings, deep groove ball bearings, flange bearings, etc.) are arranged in different mounting grooves of the side plates. These bearings are used to install and support key components (such as reduction gears, driving gears, reversing shafts, first tensioner shafts, second tensioner shafts, etc.). The use of bearings not only ensures the flexible rotation of these components, but also makes the overall structure of the device more stable and reliable, prolongs the service life of the device, and reduces possible failures caused by friction and instability between components.

[0026] In summary, the anti-entanglement bypass cable automatic lifting device has significant advantages in anti-entanglement performance, operational convenience, position control accuracy, structural stability, safety and operating efficiency, bringing better solutions to the field of circuit maintenance equipment and helping to improve the overall level of circuit repair and maintenance operations.

DETAILED DESCRIPTION

[0032] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0033] Example

[0034] Reference Figure 1-4 , an anti-entanglement bypass cable automatic lifting device, comprising a first mounting side plate 1 and a second mounting side plate 2 symmetrically arranged, and the first mounting side plate 1 and the second mounting side plate 2 are both provided with a first mounting groove, a second mounting groove, a third mounting groove, a fourth mounting groove and a fifth mounting groove.

[0035] A motor 6 is installed on the outer side of the first installation side plate 1, and an eddy current sensor bracket 5 is installed on the inner side of the first installation side plate 1;

[0036] The battery 3 and the circuit board 4 are installed on the outer side of the second installation side plate 2;

[0037] A reduction gear 17 and a driving gear 16 are installed on the first mounting side plate 1, and the driving gear 16 is meshed with the reduction gear 17, a winding drum 8 is installed on the reduction gear 17, and a winding drum gear 7 is installed on the winding drum 8, a thrust needle roller assembly bearing is installed in each first mounting groove, and the reduction gear 17 is installed on the outside of one of the thrust needle roller assembly bearings, and the winding drum 8 is installed on the other thrust needle roller assembly bearing, a deep groove ball bearing is provided in the second mounting groove on the first mounting side plate 1, and the driving gear 16 is installed on the outside of the deep groove ball bearing;

[0038] A reversing shaft 10, a first tensioning wheel shaft 11 and a second tensioning wheel shaft 12 are installed between the first mounting side plate 1 and the second mounting side plate 2. A cylindrical reversing gear 9 is installed on the reversing shaft 10. The cylindrical reversing gear 9 is fixed on the reversing shaft 10 by a nut and a retaining ring, and the cylindrical reversing gear 9 is meshed with the winding drum gear 7. Flange bearings 1 are installed in the two third mounting grooves, and the reversing shaft 10 is installed on the two flange bearings 1. Flange bearings 2 are installed in the two fourth mounting grooves, and the first tensioning wheel shaft 11 is installed on the two flange bearings 2. Flange bearings 3 are installed inside each of the fifth mounting grooves, and the second tensioning wheel shaft 12 is installed on the two flange bearings 3.

[0039] A wire puller gear 15 and a first insulating rope tensioner 13 are installed on the first tensioner shaft 11, and the wire puller gear 15 is meshed with the cylindrical reversing gear 9. The number of teeth of the winding drum gear 7 and the number of teeth of the wire puller gear 15 are in a ratio of 11:1. A second insulating rope tensioner 14 is installed on the second tensioner shaft 12, and an insulating rope is installed on the winding drum 8. The end of the insulating telescopic wire away from the winding drum 8 passes through the first insulating rope tensioner 13 and the second insulating rope tensioner 14, the inside of the eddy current sensor bracket 5 and extends downward in sequence. The first insulating rope tensioner 13 is tangent to the surface of the second insulating rope tensioner 14, and the first insulating rope tensioner 13 and the second insulating rope tensioner 14 are both provided with internal tooth grooves, and the inlet and outlet of the insulating rope are located at the internal tooth groove opening between the first insulating rope tensioner 13 and the second insulating rope tensioner 14.

[0040] In the scenario of non-stop inspection and maintenance of bypass cables, when it is necessary to lower the bypass cables, a remote controller is used to establish linkage with the circuit board control system, and the motor 6 is started. The output shaft of the motor 6 starts to rotate, driving the driving gear 16 connected thereto to rotate. Since the driving gear 16 and the reduction gear 17 are meshed with each other, the rotation of the driving gear 16 will be transmitted to the reduction gear 17, causing the reduction gear 17 to rotate accordingly. The reduction gear 17 is installed on the winding drum 8, so the winding drum 8 will rotate with the rotation of the reduction gear 17. A winding drum gear 7 is also installed on the winding drum 8. When the winding drum 8 rotates, the winding drum gear 7 will also rotate synchronously. The winding drum 8 is installed between the first mounting side plate 1 and the second mounting side plate 2 through a thrust needle roller combination bearing. The function of the thrust needle roller combination bearing is to ensure that the winding drum 8 can rotate stably between the side plates. The wire drum gear 7 is in meshing state with the cylindrical reversing gear 9 on the reversing shaft 10. When the wire drum gear 7 rotates, it will drive the cylindrical reversing gear 9 to rotate, so that the reversing shaft 10 rotates accordingly. The cylindrical reversing gear 9 is meshed with the wire puller gear 15 below, so that the rotation of the cylindrical reversing gear 9 will further drive the wire puller gear 15 to rotate. The wire puller gear 15 is installed on the first tensioner shaft 11, so the first tensioner shaft 11 will also rotate, thereby driving the first insulating rope tensioner 13 on the first tensioner shaft 11 to rotate. At the same time, the first insulating rope tensioner 13 on the first tensioner shaft 11 is tangent to the surface of the second insulating rope tensioner 14 on the second tensioner shaft 12, and the rotation of the first insulating rope tensioner 13 will drive the second insulating rope tensioner 14 to rotate together.

[0041] In this process, since the gear ratio of the winding drum gear 7 and the wire puller gear 15 is 11:1, there is a linear speed difference between the rotation of the winding drum 8 and the tensioning wheel (the first insulating rope tensioning wheel 13 and the second insulating rope tensioning wheel 14). When the insulating rope is released from the winding drum 8 and passes between the first insulating rope tensioning wheel 13 and the second insulating rope tensioning wheel 14, the insulating rope will always be in a tensioned state driven by this linear speed difference.

[0042] In addition, the insulating rope needs to pass through the inside of the eddy current sensor bracket 5 during the rising or falling process. The eddy current sensor can accurately sense the position information of the insulating rope and feed this information back to the system in real time. The system can control the lifting height of the bypass cable based on this information to ensure that the bypass cable can be lifted to a preset height position.

[0043] This working principle enables the device to effectively avoid the problem of insulating rope entanglement during the bypass cable lowering operation. Because in the traditional bypass cable lifting device, the insulating rope is prone to entanglement during the descent process due to the lack of effective tension and speed difference control, which leads to various problems, such as increasing the time and labor costs of operators, and increasing the uncertainty and danger of the operation. However, this device, through the above-mentioned mechanical structure and working principle, uses the ingenious design of transmission and speed difference between gears, and the cooperation of the tensioning wheel, while realizing the automatic lowering of the bypass cable, it solves the problem of rope entanglement and improves the reliability and safety of the device. At the same time, combined with the precise position perception of the eddy current sensor, the entire operation process is more intelligent and efficient. A single person can complete the lifting and lowering of the bypass cable through a remote control device, which greatly reduces the labor intensity of operators and reduces the risks and uncertainties in the operation process.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
