Description

Technical Field

[0001] The invention relates to the technical field of wire rope maintenance, and in particular to a portable wire rope oiling robot. Background Art

[0002] The lubricating oil on ship loading and unloading wire ropes, port gantry crane wire ropes, etc. will harden after long-term use and lose its lubrication and maintenance function. The manual cleaning and maintenance process takes a long time and is greatly affected by weather factors. In addition, manual operation has the disadvantages of incomplete oil removal and uneven manual grease application.

[0003] The use of a portable wire rope oiling robot can reduce the risk of personnel working at heights and improve efficiency, thereby achieving the goal of reducing costs and increasing efficiency.

[0004] At present, the robots used for cleaning and maintaining wire ropes are equipped with heavy oil pipes and air pipes (hereinafter referred to as combined pipelines), which make the robots bear a large load. At the same time, a staff member is required on the ground to assist in the movement of the combined pipeline to prevent the pipeline from being scratched.

[0005] The current cleaning and maintenance workflow for wire ropes is roughly as follows: move the oil truck to the bottom of the wire rope to be maintained, connect the combined pipeline, fix the oiling robot to the wire rope, click the start button on the remote control, and the robot will automatically clean, lubricate and maintain the wire rope. Since the staff need to lift the oiling robot and the combined pipeline to fix them to the wire rope during operation, they are heavy and inconvenient to operate.

[0006] Based on this, it is necessary to provide a complete set of portable wire rope oiling robots for daily maintenance such as cleaning and lubrication of ship loading and unloading wire ropes and port gantry crane wire ropes. The advantages are that they are light and easy to operate, and do not require bulky oil trucks and combined pipelines. At the same time, the portable wire rope oiling robot can match the appropriate oiling module according to the thickness of the wire rope, and carry a walking robot to clean and lubricate the wire rope. It reduces the weight of the equipment, reduces the difficulty of operation for staff, improves work efficiency and reduces costs. Summary of the invention

[0007] 1. Technical issues

[0014] The oil tank fixed in the shell is connected to the lower oil filling module and the upper oil filling module through oil pipes to supply oil, and an electric oil pump arranged on the oil pipe line is also fixed in the shell for active pumping of lubricating oil.

[0015] Preferred technical solution 2: one end of the connecting device is connected to the shell, and the other end is connected to the walking robot.

[0016] Optimal technical solution three: The contact surfaces of the lower oil injection module and the upper oil injection module with the steel wire rope are provided with evenly distributed oil drain holes, and the lubricating oil pumped in the oil pipe is squeezed out from the oil drain holes.

[0037] The lower oil injection module 2.8 and the upper oil injection module 2.9 are made of nylon, 3D printed and polyurethane materials, and are machined;

[0038] The fuel tank 2.1 is made of resin and formed by 3D printing;

[0039] The oil tank 2.1 fixed in the housing 1 is connected to the lower oil injection module 2.8 and the upper oil injection module 2.9 through oil pipes to supply oil, and an electric oil pump 2.5 arranged on the oil pipe line is also fixed in the housing 1 for active pumping of lubricating oil.

[0040] The walking robot 4 moves on the steel wire via built-in walking wheels. When necessary, one end of the connecting device 3 is connected to the shell 1, and the other end is connected to the walking robot 4, which is used to drive the portable oiling device to walk on the steel wire. The portable oiling device itself has no power, so it must be used in conjunction with the walking robot.

[0041] See also Figure 2-Figure 3, a portable wire rope oiling robot, wherein the housing 1 is composed of an upper cover 1.1, a sliding cover 1.3, a lower cover 1.4, a flip cover 1.7, and a rear cover 1.8. The upper cover 1.1 and the lower cover 1.4 are fixed to the upper and lower ends of the front side of the rear cover 1.8, so that a window is formed between the upper cover 1.1 and the lower cover 1.4. The sliding cover 1.3 slides up and down on the slide rail 1.5 on the lower cover 1.4. The sliding cover 1.3 slides to intermittently cover the window. The bottom end of the flip cover 1.7 is hinged 1. 6 is rotatably mounted with the lower cover 1.4, the top of the flip cover 1.7 is connected to the upper cover 1.1 through a buckle lock 1.2, and the upper oiling module 2.9 is detachably mounted on the fixed base 2.10 inside the upper cover, and the lower oiling module 2.8 is detachably mounted on the fixed base 2.10 on the top telescopic end of the electric push rod 2.2. After the flip cover is opened to release the connection with the upper cover, the sliding cover is slid down to expose the window, so as to facilitate the replacement of the internal upper oiling module 2.9 and the lower oiling module 2.8;

[0042] One end of the connecting device 3 is connected to the upper cover 1.1, and the other end is connected to the outer shell of the walking robot 4. The connecting device can be in various forms, such as a rope, a connecting rod, etc.

[0043] See also Figure 2-Figure 3 , a portable wire rope oiling robot, the oil tank 2.1 is fixed to the rear cover 1.8 through the bolt holes at the four corners, and an air intake assembly 2.12 is arranged on the oil tank cover 2.11 on the oil tank 2.1, and the air intake assembly 2.12 is used to keep the pressure inside and outside the oil tank 2.1 equal, and a liquid level detection device 2.3 is also arranged in the oil tank 2.1, and the liquid level detection device 2.3 is used to monitor the lubricating oil level in the oil tank 2.1;

[0044] The joint on the oil pipe is a quick joint. The oil pipe includes an oil inlet pipe 2.4 connected to the oil tank 2.1, an oil outlet main pipe 2.6 and an oil outlet branch pipe 2.7. The electric oil pump 2.5 is fixedly connected to the rear cover 1.8 through the mounting hole of the motor base. One end of the oil inlet pipe 2.4 is connected to the oil outlet of the oil tank 2.1, and the other end is connected to the oil suction port of the electric oil pump 2.5. The oil outlet of the electric oil pump 2.5 is connected to the oil outlet main pipe 2.6. The oil outlet main pipe 2.6 is connected to the lower oil filling module 2.8 and the upper oil filling module 2.9 through two oil outlet branch pipes 2.7.

[0045] The operation process of the portable wire rope oiling robot is as follows: fill the oil tank 2.1 with lubricating oil, tighten the oil tank cover 2.11, open the sliding cover 1.3 and the flip cover 1.7, hang the portable wire rope oiling robot on the wire rope, close the sliding cover 1.3 and the flip cover 1.7, start the electric push rod 2.2, and after reaching the specified stroke, open the air intake component 2.12 to ensure that the pressure inside and outside the oil tank 2.1 is equal. The connecting device 3 is connected to the walking robot 4, and the electric oil pump 2.5 is started. The lubricating oil in the oil tank 2.1 will pass through the electric oil pump 2.5 from the oil inlet pipe 2.4 to the oil outlet main pipe 2.6, and then enter the lower oil injection module 2.8 and the upper oil injection module 2.9 through the oil outlet branch pipe 2.7.

The oil output of the electric oil pump 2.5 matches the speed of the walking robot 4, ensuring that the lubricating oil can be evenly applied to the wire rope, so that the oil film thickness on the surface reaches about 0.5-1mm.

[0047] The oil tank 2.1 is provided with a conduit, and when the oil tank 2.1 is tilted, all the lubricating oil on the top can be transported to the bottom of the oil tank 2.1 through the siphon principle. When the liquid level detection device 2.3 detects that the oil level in the oil tank 2.1 is low, an alarm will be issued to remind the user to add lubricating oil.

[0048] It is worth noting that the electric oil pump 2.5, electric push rod 2.2, walking robot 4 and liquid level detection device 2.3 mentioned in this embodiment, as well as their supporting power supply and control switch can also be provided by the manufacturer.
