Description
Technical Field
[0001] This utility model belongs to the technical field of track maintenance equipment, and in particular relates to an oiler for crane tracks with an automatically opening and closing rocker arm. Background Technology
[0002] Cranes are specialized equipment used for handling large materials in industrial production, and their operation and maintenance are extremely important. During operation, the crane wheels constantly rub against the rails, requiring regular lubrication to prevent wear and tear on the wheels and crane rails, which would ultimately affect their service life.
[0003] The traditional method of maintenance is to apply lubricant manually. However, this method has many drawbacks. First, the crane must be stopped before workers can work, which can easily cause delays in normal production. Second, workers need to work at heights, which poses a certain threat to their personal safety. Finally, manual lubrication is limited by the skill level of the workers, and improper operation can easily lead to the lubricant being applied to the top of the track, causing the wheels to slip and affecting safe production.
[0004] With advancements in technology, oilers were invented, primarily used for lubricating the wheel flanges of various bridge cranes and gantry cranes. They improve dry friction between the wheels and rails by forming an oil film on both sides of the track, effectively solving the problem of rail wear. However, oilers only need to operate 2-3 times a month, for about 15 minutes each time, leaving a long off-duty period. The oiling wheel operates on a contact-type lubrication principle. Due to the spring structure, the existing oiler's wheel remains firmly attached to the rail, resulting in constant dry friction during off-duty periods. This significantly reduces its lifespan, increases maintenance and spare parts replacement frequency, and greatly increases the operating cost. To address this, on-site personnel typically use wire to pull the boom away from the crane frame during off-duty periods, reducing wear. However, this method requires workers to climb to the maintenance platform to operate the oiler, a cumbersome and dangerous process. Utility Model Content
[0005] The purpose of this utility model is to provide a crane rail oiler with an automatically opening and closing rocker arm, so as to solve the technical problem that the oiling wheel of the existing oiler cannot automatically leave the rail, causing it to dry rub against the rail when not in operation.

[0022] like Figure 1-4As shown, the crane rail oiler with automatic rocker arm opening and closing of this utility model includes a control box 1 and oiling components that are interconnected. The oiling components are arranged in pairs on the left and right sides above the rail 6. The rear side of the oiling component is provided with a support frame 4, and its rear end is fixedly connected to the support frame 4. The two oiling components are suspended on both sides of the rail 6 in a mirror image manner through the support frame 4. The control box 1 is located above the two oiling components, and its rear end is also fixedly connected to the support frame 4. The support frame 4 provides support and fixation. During operation, the inner ends of the oiling components are respectively attached to the corresponding sides of the rail 6 under the control of the control box 1. The control box 1 provides lubricating oil to the oiling components. Under the control of the control box 1, the oiling components apply oil to the corresponding sides of the rail 6. After the oiling is completed, the control box 1 stops supplying oil to the oiling components and controls the oiling components to move to the corresponding outer side of the rail 6, thereby disengaging from the rail 6.
[0023] The oiling assembly includes a rocker arm 2 and an oiling wheel 3. The rear end of the rocker arm 2 is fixedly connected to a support frame 4. The support frame 4 provides support for the oiling assembly through the rocker arm 2. The rocker arm 2 is associated with the control box 1 through a corresponding circuit. The oiling wheel 3 is fixedly installed at the front end of the rocker arm 2. Under the control of the control box 1, the rocker arm 2 can drive the oiling wheel 3 to rotate inside and outside the track 6, thereby realizing the conversion between the oiling wheel 3 and the track 6 being close and far apart, thus avoiding dry friction between the oiling wheel 3 and the track 6 when not in operation. The upper end of the oiling wheel 3 is provided with a connected oil supply pipe 31. The oiling wheel 3 is connected to the control box 1 through the oil supply pipe 31. During operation, the control box 1 provides lubricating oil to the oiling wheel 3 through the oil supply pipe 31, and then the oiling wheel 3 applies oil to the track 6.
[0024] The rocker arm 2 includes a fixed base 21, a telescopic assembly 24, and a rotating arm 23. The rear end of the fixed base 21 is fixedly connected to the support frame 4, and the support frame 4 provides support for the rocker arm 2 through the fixed base 21. The rotating arm 23 is located on the front side of the fixed base 21, and its rear end is rotatably connected to the front end of the fixed base 21 through a corresponding rotating shaft 22. The oiling wheel 3 is fixedly installed on the front end of the rotating arm 23. The telescopic assembly 24 is located on the side of the fixed base 21 that is not parallel to the rotating shaft 22. In this embodiment, the rotating shaft 22 is vertically arranged, and the telescopic assembly 24 is horizontally arranged on the outside of the fixed base 21. Its rear end is rotatably connected to the support frame 4 via a corresponding adapter 42, and its front end is rotatably connected to the top surface of the rotating arm 23. The telescopic assembly 24 includes a base 25 and a telescopic rod 26. The rear end of the base 25 is rotatably connected to the adapter 42 on the front side of the support frame 4. The rear end of the telescopic rod 26 is connected to the base 25, and its front end is rotatably connected to the rotating arm 23. The telescopic assembly 24 is associated with the control box 1 through the base 25. Under the control of the control box 1, the base 25 drives the telescopic rod 26 to extend or retract, depending on the relationship between the base 25 and the telescopic rod 26. Depending on the telescopic function, the telescopic component 24 can be of various types, such as hydraulic cylinder type, pneumatic type, and electric push rod type. In this embodiment, an electric push rod with lead screw and gear drive is used. The rear side of the telescopic rod 26 is located inside the base 25, the front end of the telescopic rod 26 passes through the front end face of the base 25 and extends to the front side of the base 25, the rear end of the telescopic rod 26 is designed as a lead screw, and a corresponding nut is fitted on its outer ring. The outer ring of the nut is designed as a gear. A motor parallel to the telescopic rod 26 is installed inside the base 25, and the output shaft end of the motor is matched with the outer ring gear of the nut. The drive wheel and telescopic assembly 24 are connected to the control box 1 via a motor. During operation, the motor starts and rotates in the forward or reverse direction under the control of the control box 1, thereby extending or retracting the telescopic rod 26 through the meshing rotation of the drive wheel and nut. The electric push rod is a common technology in the field of electromechanical engineering. Its internal structure as a component is not shown in the attached figure, and its operation and control method will not be described in detail here. Under the action of the telescopic assembly 24, the rotating arm 23 rotates inside and outside the track 6 around the rotating shaft 22, thereby driving the oiling wheel 3 to contact or move away from the track 6.
[0025] The control box 1 includes a box body 11 and a box cover 12. The control box 1 is located on the front side of the support frame 4 above the oiling assembly, with its rear wall fixedly connected to the support frame 4. The box cover 12 is located at the upper end of the box body 11, with its bottom end rotatably connected to the middle of the front side wall of the box body 11, and its top rear side overlapping the rear side of the top surface of the box body 11. This arrangement facilitates the opening of the box cover 12 for inspection and maintenance of the components inside the box body 11. A corresponding pair of locking plates and latches are provided between the top surface of the box cover 12 and the top surface of the box body 11. The two can lock the cover 12 with an external lock. An oil tank 13 and an oil pump 14 are located on the rear wall of the inner cavity of the housing 11. The oil pump 14 is located on the lower side of the rear wall of the housing 11, and the oil tank 13 is located above the oil pump 14. The inlet of the oil pump 14 is connected to the oil tank 13 via a corresponding oil inlet pipe 15, and its outlet is connected to an oil delivery pipe 31 that passes through the side wall of the housing 11, thus achieving connection between the housing 11 and the oiling assembly. A control panel 16 is located on the front wall of the inner cavity of the housing 11. It is associated with the oil pump 14 and the oiling assembly through the corresponding circuit. During operation, it can control the amount of oil dispensed and the duration of oiling each time through the oil pump 14, and can control the oiling frequency and duration of each oiling through the oiling assembly, thereby realizing the overall operation control of the oiler. In this embodiment, a pair of oil pumps 14 corresponding to the two oiling assemblies are provided on the left and right sides of the rear wall of the housing 11. Both oil pumps 14 are associated with the control board 16. The outlet ends of the two oil pumps 14 are respectively connected to the oil supply pipeline 31 of the corresponding side oiling assembly. The two oil pumps 14 are respectively provided with corresponding oil storage tanks 13 above them. Both oil storage tanks 13 are connected to the corresponding oil pumps 14 through the corresponding oil inlet pipelines 15. The control board 16 can control the oiling status on both sides of the track 6 separately through the two oil pumps 14 and the two oiling assemblies. The front side of the front wall of the housing 11 is provided with control buttons 17 associated with the control board 16. The operator can preset and control the operating data of the oiler through the control buttons 17.
[0026] Furthermore, a dust cover 5 with an opening facing downwards is provided above the oiling assembly, and its rear side is fixedly connected to the support frame 4. Under the action of the support frame 4, the dust cover 5 is suspended above the oiling assembly, covering the upper middle part of both oiling assemblies in its inner cavity. A transparent observation window is provided on the front side wall of the dust cover 5, and the operator can observe the working status of the oiling assembly inside in real time through the observation window. In this embodiment, the front side wall of the dust cover 5 is set as an inclined surface that gradually slopes forward from top to bottom, and the observation window is located in the middle of the front side wall. This setting makes it more convenient for the operator to observe the contact between the oiling wheel 3 and the track 6 and the oiling work when the oiling wheel 3 is working.
[0027] Furthermore, corresponding air outlets are provided on the side walls of the housing 11 and the dust cover 5 to facilitate the exchange and flow of air between the housing 11 and the outside air, which is more conducive to the heat dissipation of the control box 1 and the oiling components.
[0028] Under normal conditions, the telescopic rod 26 of the telescopic assembly 24 is in a retracted state. It drives the oiling wheel 3 to the outward flipped position away from the track 6 through the rotating arm 23, and the rocker arm 2 is in an open state. When the oiler needs to apply oil, the base 25 of the telescopic assembly 24 drives the telescopic rod 26 to extend under the control of the control plate 16, thereby pushing the corresponding rotating arm 23 to rotate around the rotating shaft 22 towards the track 6. Then, the rotating arm 23 drives the corresponding side oiling wheel 3 to flip towards the inward side of the track 6 until the inner side of the oiling wheel 3 is in contact with the corresponding side of the track 6. In this way, the rocker arm 2 is adjusted to the closed state. At this time, the oil pump 14 on the corresponding side starts to work under the control of the control plate 16. It delivers the lubricating oil in the oil tank 13 to the oiling wheel 3 through the cooperation of the oil inlet pipe 15 and the oil delivery pipe 31. Finally, the oiling wheel 3 achieves the oiling of the track 6. After the oiling work is completed, firstly, the oil pump 14 stops working under the control of the control panel 16. Then, the telescopic rod 26 of the telescopic assembly 24 retracts under the control of the control panel 16, thereby driving the rotating arm 23 to rotate around the rotating shaft 22 in a direction away from the track 6, and then driving the oiling wheel 3 to flip outward away from the track 6 until the rocker arm 2 returns to its initial open position, realizing the separation of the oiling wheel 3 from the track 6, ready for the next use of the oiler.
[0029] This utility model relates to an automatic rocker arm crane rail oiler, which is suspended above the rail 6 via a support frame 4. The rocker arm 2 allows the oiling wheel 3 to automatically rotate inward and outward and open and close under the control of the control box 1, thus enabling it to detach from the rail 6 when not in operation. This improves the mobility and intelligence of the oiler, avoids dry friction between the rail 6 and the oiling wheel 3 when not in operation, avoids the impact of dry friction on the service life of the oiling wheel 3, and extends the service life of the oiler. It also reduces the frequency of maintenance and replacement of spare parts, greatly reducing the operating cost of the oiler. Furthermore, the operation of this automatic rocker arm crane rail oiler is more convenient and simple, avoiding the safety hazards of manual operation and improving operational safety. It not only improves the safety of oiling the crane rail 6 but also avoids downtime, reduces the waste of working hours caused by downtime, reduces the delay of crane rail 6 oiling on normal production, improves production efficiency, and makes the oiling operation more standardized, reducing the impact of improper oiling on production safety.
