Description

Technical Field

[0001] This utility model belongs to the technical field of metallurgy and casting equipment, specifically relating to an automatic lubrication device for the chain of a linear casting machine for nickel anode plates. Background Technology

[0002] In the metallurgical and foundry industries, the linear transfer of molten liquid metal requires the use of chains to drive casting trolleys. Currently, the industry often uses a method of suspending oil drums to lubricate only the surface of the chain, without addressing the internal lubrication between the chain and the pins. This leads to a high risk of pin breakage due to wear during prolonged continuous use. Traditional automatic lubrication systems require precise positioning or have stringent environmental requirements, which are unsuitable for the harsh working environments of the metallurgical and foundry industries. Utility Model Content

[0003] To meet usage requirements and extend the service life of chains, an automatic lubrication device is designed to achieve the lubrication requirements between the chain and the pins.

[0004] Therefore, the present invention adopts the following technical solution: An automatic lubrication device for the chain of a linear casting machine for nickel anode plates includes a base module, a moving module, a floating oil gun module, and a lubrication control system. The base module is equipped with a height-adjustable welded pad assembly, a counterweight return mechanism with detachable counterweight blocks, and an adjustable hydraulic damper at the end. The moving module includes a pneumatic-spring dual redundant drive mechanism, a baffle follower mechanism, and a photoelectric sensor. The front end of the baffle follower mechanism is provided with a wear-resistant pulley, which is linked with the baffle of the casting trolley. The floating oil gun module includes a conical floating positioning gun head driven by dual cylinders. The gun head has a built-in spring to achieve ±5mm adaptive centering. A circular boss is provided at the front end to open the chain funnel oil cup and insert it into the pin groove. The lubrication control system integrates a pneumatic pump, MPV valve, and distributor. It regulates oil pressure through a pressure reducing valve and is equipped with limit switches and magnetic switches to monitor the timing of actions. In case of abnormality, it triggers the pull-back cylinder for emergency reset.

[0005] Furthermore, the base module's pad assembly includes a screw, a spherical washer, and a locking nut, which are welded and fixed to the foundation embedded parts after three-dimensional angle adjustment.

[0006] Furthermore, the return mechanism of the counterweight converts the gravitational potential energy of the counterweight into the reset power of the device through the pulley system, and the number of counterweights can be increased or decreased to adjust the return pull force.

[0007] Furthermore, the pneumatic-spring dual redundant drive mechanism of the moving module includes a guide rod, a guide sleeve, and a reset spring, which forces the device to reset when the air supply is interrupted.

[0008] Furthermore, the photoelectric sensor is installed on the side of the baffle to detect the distance between the baffle and the trolley in real time and to trigger an alarm when the distance exceeds the limit.

[0009] Furthermore, the floating oil gun module adopts a quick-release structure, with the gun head and the oil injection line connected by threads, supporting quick replacement.

[0010] Furthermore, the pneumatic pump of the lubrication control system is directly connected to the oil tank, and continuous oil supply is achieved by changing the oil tank.

[0011] Furthermore, the initial position of the hydraulic damper is adjusted by a screw to adapt to the stroke compensation requirements after chain wear.

[0012] Furthermore, the limit switch is located at the end of the left and right strokes of the moving module, detects the reset state of the detection device, and activates the pull-back cylinder if the trigger timeout fails to reset.

[0013] The beneficial effects of this utility model are as follows: 1. Precise internal lubrication: Replacing the original dripping method, it achieves effective lubrication inside the chain, reducing wear caused by poor internal lubrication.

[0014] 2. Automation: The system adopts an automatic lubrication method, and the lubrication pump station can be operated simply by changing the oil tank, which saves labor costs.

[0015] 3. Strong environmental adaptability: The oil pressure of the pump station is regulated by a pressure reducing valve, which can adapt to the operating requirements at different temperatures.

[0016] 4. Easy maintenance: The oil gun adopts a floating alignment structure, which can effectively lubricate the chain even if there is partial wear.

[0017] 5. The bottom limit is adjustable, allowing the initial position of the moving parts of the equipment to be adjusted according to the wear of the chain. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: 1. Base module The base part is as follows Figure 3 The main functions shown are to install the equipment's transmission components, adjust the equipment's height, and provide return power. Height adjustment relies on a self-made adjusting shim 102. Adjustment of the height and angle is achieved by adjusting a self-made screw and a bottom spherical washer. Finally, the position is secured using a screw at the top of the screw and a nut at the top. During use, the adjusting shim 102 needs to be welded to the pre-embedded shims in the foundation after the height and angle have been adjusted. The base is equipped with a counterweight and pulleys. The gravity potential energy generated by the movement of the counterweight during equipment operation provides return power. The counterweight uses a detachable counterweight block, allowing for adjustment of the return tension. Additionally, to prevent excessive impact during the return phase, a hydraulic damper is installed at the end of the return stroke. This hydraulic damper can be adjusted to its initial position according to chain wear to meet usage requirements.

[0021] 2. Mobile module Transmission components such as Figure 4The device mainly consists of various cylinders and corresponding linear guides 203104, which are further divided into a pull-back section and a baffle follower section. The pull-back section is designed to prevent air supply interruption during operation. It uses a guide rod 206 and a guide sleeve with a spring 205. When the air supply is interrupted, the device can quickly spring back under the action of the spring 205 to avoid damage. The baffle follower section is used to move the device along with the mold carriage baffle mounted on the chain during the operation of the line. A pulley is provided at the front to prevent the baffle from wearing out too quickly due to frequent contact. The positioning section is the part that drives the oil gun to extend, which plays a transmission role.

[0022] 3. Oil injection module The oil filling part is as follows: Figure 5 Installed on top of the movable part, its function is to install the oil gun part, which is moved forward and positioned by the oil injection cylinder 306. This part is equipped with an adjustment mechanism to achieve fine adjustment of the height of the oil gun part.

[0023] 4. Oil gun module Oil gun part such as Figure 6 The part shown at the front of the device is used to inject oil between the chain and the pin. The nozzle area uses a conical floating positioning device, and the chain pin part uses a matching conical groove. A spring 205 structure inside the device can automatically align itself by floating positioning if the relative position of the oil injection port is inaccurate. Because this part needs to withstand repeated large impacts, it is designed as a replaceable structure for easy replacement after wear. The oil gun is driven by two cylinders simultaneously to prevent excessive uneven load on the cylinders and ensure their service life. To prevent the cylinders from moving asynchronously, the connecting plate 305 and the oil gun head 401 are not completely securely fastened. The front end of the oil gun head 401 has a circular perforated boss that can effectively push open the funnel-shaped oil cup on the chain.

[0024] 5. Lubrication system The lubrication system primarily employs a combination of pneumatic pumps, MPV valves, and distributors. It simultaneously lubricates both the lubrication equipment and the chain. The system regulates hydraulic pressure and flow rate by adjusting the intake air pressure.

[0025] The specific working process of the automatic chain lubrication device: As the chain drives the upper mold carriage to move, the baffle extends through the gap. After the carriage starts moving, it drives the baffle forward together. (The initial position of the baffle is set to 100mm. After 2 seconds, the carriage moves about 147mm. At this time, the baffle and the carriage move together about 47mm.) After the carriage moves for 2 seconds (starting from the 3rd second), the positioning cylinder extends. At the 5th second, the oil injection cylinder 306 (4 small cylinders) extends. Oil injection begins at the 6th second and lasts for 3 seconds. After oil injection is completed, the oil injection cylinder 306 and the positioning cylinder retract simultaneously. After the oil injection cylinder 306 retracts, the baffle cylinder retracts, and the device returns to the starting position under the pulling force of the weight.

[0026] With prolonged use, as the chain wears down, the trolley will stop closer and closer to the baffle each time. A photoelectric sensor is installed on the side of the baffle to detect the distance between the trolley and the baffle. When the photoelectric sensor is triggered, an alarm is issued, and the position of the hydraulic damper is manually adjusted.

[0027] Two limit switches 101 are installed near the limit block area at the left and right ends of the travel to detect whether the action has reached the position.

[0028] Upon arrival at the designated time or location (both can be used), if the following situation occurs: 1. When the oil filling cylinder 306 or the baffle cylinder cannot retract (the magnetic switch at the retraction position is not triggered).

[0029] 2. The automatic lubrication device's automatic oil injection moving part did not reach the designated area within the specified time (the magnetic switch at the extension position was not triggered).

[0030] 3. The left limit switch 101 is triggered within the set time, and it is detected that the trolley has not retracted under the action of the counterweight.

[0031] 4. The right limit switch 101 was not triggered within the set time, and it was detected that the trolley did not return to the starting position under the action of the counterweight.

[0032] At this time, the pull-back cylinder 204 directly moves (extends) to pull back the entire oil injection device to avoid damage to the equipment. A spring 205 is set next to the pull-back cylinder 204 to prevent the pull-back cylinder 204 from failing to perform the pull-back (extend) action in the event of a gas shortage (the pull-back cylinder 204 is in a compressed state when the system is working normally).
