Description

Technical Field

[0001] This utility model relates to the field of circulating cable maintenance technology, specifically to an automatic oiling device for circulating cable wire ropes. Background Technology

[0002] Circulating steel wire ropes are widely used in hydrological monitoring work in my country. They are extensively used for traction of hydrological monitoring test equipment, reciprocating traction of personnel gondolas, and other tasks. Due to geographical limitations, their installation methods vary, with some spanning both banks of a river and ranging in length from 600 meters to 2500 meters. Because of their length and large span, the maintenance of these steel wire ropes is particularly important. Hydrological monitoring circulating steel wire ropes are exposed to the field environment for extended periods and require regular oiling and maintenance.

[0003] Currently, most hydrological workers still rely on manual oiling for wire rope maintenance, but this method suffers from low efficiency. To address the problems associated with manual operation, an automatic wire rope oiling and maintenance device has been disclosed in application number CN202422070142.7. This device mainly comprises a closed cylinder capable of injecting grease, fitted around the rope. The device is then manually or via a drive mechanism pulled to slide around the rope, thus applying oil. However, this device requires a traction device to move and apply oil on a fixed wire rope, making it unusable on movable circulating wire ropes. Furthermore, it suffers from poor adaptability in oiling: when used on pullable ropes, long ropes, or when continuous oiling operations are required, the oiling efficiency is low, making it difficult to meet the demands of high-efficiency production, thus resulting in poor adaptability. Therefore, we propose an automatic oiling device for circulating wire ropes to solve the problems encountered in existing technologies. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 As shown, the automatic oiling device for circulating wire rope includes a lower cylinder 1 and an upper cylinder 2 that are hinged to each other. The upper end of the upper cylinder 2 is provided with an oil injection port and a plug is provided in the thread of the oil injection port that can be removed. The lower cylinder 1 is provided with a pull plate 3 that is elastically movable and a pull rod 4 is provided on the left end of the pull plate 3. The axis of the pull plate 3, the lower cylinder 1 and the upper cylinder 2 are all provided with through holes 17 for passing through the circulating rope 5. Pull rings 18 are provided on both sides of the left end of the lower cylinder 1 for fixing the lower cylinder 1. By using the lower cylinder 1 and pull ring 18 in conjunction with the rope fixing device, the entire oiling equipment can be kept stationary, completely replacing the traditional moving oiling mode. The elastic pull plate 3 slowly moves to the right, actively squeezing the grease to wrap around the circulating rope 5. Combined with the movement of the circulating rope 5 itself, dynamic oiling is achieved, eliminating the need for the device to slide with the circulating rope 5.

[0023] Example 2: Reference Figure 1 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0024] Specifically, Figure 1 In the middle, a hollow rod 13 is welded and connected to the right end of the lower cylinder 1. A pull rod 4 is welded to the left end of the pull plate 3 for pulling the pull plate 3. One end of the pull rod 4 passes through the left end of the lower cylinder 1. A tension spring 15 is detachably provided between the left end of the pull plate 3 and the inner wall of the hollow rod 13. A part of the tension spring 15 is inside the hollow rod 13. As the oil level decreases, the tension spring 15 causes the pull plate 3 to gradually rebound and move to the right, squeezing the grease into the circulating rope 5. The hollow rod 13 is used to provide a reset for the pull plate 3 and to limit the position of the tension spring 15. It should be noted that both ends of the tension spring 15 are integrally provided with open arc-shaped hooks, and the left end of the pull plate 3 and the inner wall of the hollow rod 13 are provided with L-shaped hooks for attaching with the open arc-shaped hooks, which facilitates the disassembly of the tension spring 15.

[0025] Specifically, Figure 1 In the middle, the pull plate 3 has a guide opening 11 vertically opening upward along its axis, and the guide opening 11 is connected to the through hole 17; The guide port 11 provides an installation channel for the insert plate 12 and connects to the channel of the circulating rope 5.

[0026] Specifically, Figure 3 In the middle, a latex sealing ring 10 is installed inside the through hole 17, and an insert plate 12 is slidably installed inside the guide port 11. The lower end of the insert plate 12 is arc-shaped. The latex sealing ring 10 enhances the sealing performance, and the lower end of the insert plate 12 is pressed against the upper surface of the circulating rope 5 to adapt to the circulating rope 5 and ensure its smooth movement.

[0027] Specifically, Figure 3 In the middle, the top walls of the upper cylinder 2 are equipped with rotating connecting wheels 14 at both ends via brackets for rolling connection with the upper surface of the circulating rope 5; the connecting wheels 14 assist the rope to move smoothly and reduce wear on the sealing ring.

[0028] Example 3: Reference Figure 1 , Figure 4 , Figure 3 , Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0029] Specifically, Figure 1 In the middle, a limiting member 8 is provided at the left end of the lower cylinder 1. The limiting member 8 includes a rotatably disposed pressure plate 81, one end of which passes through the extension end of the lower cylinder 1. One end of the pressure plate 81 passes through the lower cylinder 1 to form a limit.

[0030] Specifically, Figure 4 In the middle, two annular grooves 9 are opened on the outer periphery of the pull rod 4, and the annular grooves 9 are engaged with the upper end of the pressure plate 81; By fixing the pull plate 3 at different positions, the distance between the two annular grooves 9 is 5cm. The upper end of the pressure plate 81 is engaged with the right annular groove 9, and the oil storage space at the right end of the pull plate 3 is the largest. Conversely, the upper end of the pressure plate 81 is engaged with the left annular groove 9, and the oil storage space is the smallest. The amount of grease can be added reasonably according to the usage.

[0031] Specifically, Figure 5 In the middle, one end of the pressure plate 81 is rotatably set with the left end of the lower cylinder 1 via a pin. A support plate is welded to the left end of the lower cylinder 1, and a circular seat 83 is welded to the upper surface of the support plate. A cylinder 82 is inserted through the circular seat 83. The right side of the cylinder 82 is rotatably set with the pressure plate 81 via a pin. A spring is also welded between the lower end of the cylinder 82 and the bottom wall of the circular seat 83. The cylinder 82 stabilizes the pressure plate 81, while the spring inside the circular seat 83 is pressed by the cylinder 82, ensuring that the pressure plate 81 automatically resets.

[0032] Specifically, Figure 4 and Figure 3 In the middle, the outer periphery of the pull rod 4 is fixed with a collar 6 by bolts, and the left end of the lower cylinder 1 is fixed with a proximity sensor 7 and a buzzer 16 by bolts. The detection end of the proximity sensor 7 is perpendicular to the horizontal movement trajectory of the collar 6. The proximity sensor 7 detects the collar 6, and the pull plate 3 is in a fully returned state at this time, with the oil level at its minimum, which can realize the detection and alarm of insufficient oil level.

[0033] Working principle: The device can be fixed in place by using the pull rings 18 on both sides of the left end of the lower cylinder 1 in conjunction with the fixing devices such as ropes. Then, the quick-release lock between the lower cylinder 1 and the upper cylinder 2 is opened, and the two cylinders are unfolded around the hinge. The circulating rope 5 is passed through the through hole 17 of the axis of the lower cylinder 1 and the upper cylinder 2 and the through hole 17 of the pull plate 3. Then it is inserted into the insert plate 12 into the guide port 11. Then the lower cylinder 1 and the upper cylinder 2 are closed and the quick-release lock is locked. Pulling the lever 4 causes the pull plate 3 to move to the left until one of the annular grooves 9 on the lever 4 is aligned with the pressure plate 81. Then, under the action of the spring, the upper end of the pressure plate 81 is engaged in the annular groove 9, thus completing the limiting of the pull plate 3. Unscrew the threaded plug inside the oil inlet and inject grease into the space between the right end of the pull plate 3 and the inner walls of the lower cylinder 1 and the upper cylinder 2. After filling, tighten the plug. Next, press the pressure plate 81 to disengage its upper end from the annular groove 9. Under the restoring force of the spring, the pull plate 3 slowly moves to the right, directly squeezing the grease to wrap around the circulating rope 5. Start the drive device to move the circulating rope 5. During the oiling process, when the pull plate 3 moves to the right, it simultaneously drives the collar 6 around the pull rod 4 to move. The proximity sensor 7 at the left end of the lower cylinder 1 detects the position of the collar 6 in real time. When the collar 6 moves to the detection end of the proximity sensor 7, it indicates that the oil level at the right end of the pull plate 3 is insufficient, that is, the grease is consumed to a minimum. The proximity sensor 7 triggers a signal, and the buzzer 16 at the left end of the lower cylinder 1 sounds an alarm to remind you to replenish the grease. Finally, unfold the upper cylinder 2 and take out the insert plate 12 to separate the device from the circulating rope 5 to complete the oiling process.
