Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning devices, specifically relating to a hydraulic cylinder cleaning machine. Background Technology

[0002] In industrial production, hydraulic cylinders, as key devices that convert hydraulic energy into reciprocating linear motion mechanical energy, are widely used. The cleanliness of the cylinder body plays a decisive role in the overall stability and service life of the product. During long-term use, oil stains, iron filings, dust, and other impurities easily accumulate on the inner wall of the cylinder. These impurities not only accelerate the wear of components such as the piston and piston rod, leading to decreased sealing performance and causing malfunctions such as oil leaks and jamming, but may also contaminate the hydraulic oil, affecting the normal operation of the entire hydraulic system. Therefore, regular and effective cleaning of the cylinder body is crucial. Currently, the commonly known methods for cleaning hydraulic cylinders generally use water tanks larger than the cylinder's volume to store the cleaning fluid for cleaning operations. This traditional method has significant drawbacks, the most prominent being the large tank volume, which necessitates a large amount of cleaning fluid. Firstly, the use of large quantities of cleaning fluid means higher procurement costs. As a consumable, frequent purchases of cleaning fluid increase operating expenses. Secondly, the storage and management of the cleaning fluid become more complex, requiring larger storage space to house the large-capacity tank, and ensuring the storage environment meets requirements to prevent fluid deterioration or leakage. Furthermore, improper disposal of large quantities of used cleaning fluid can pollute the environment. In today's increasingly stringent environmental regulations, this undoubtedly places greater environmental pressure on businesses. Moreover, the large-capacity tank results in a bulky cleaning equipment, increasing its footprint. For some production workshops with limited space, this may not meet the installation requirements, limiting the application scenarios of the cleaning equipment. Given the numerous shortcomings of traditional hydraulic cylinder cleaning methods, developing a new type of hydraulic cylinder cleaning machine to solve the problems of large tank volume and large cleaning fluid consumption has significant practical implications and broad market prospects. Utility Model Content

[0003] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a hydraulic cylinder cleaning machine.

[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows: A hydraulic cylinder cleaning machine includes a cleaning mechanism, wherein a telescopic placement mechanism is connected and installed in the cleaning mechanism; The cleaning mechanism is equipped with a rack and pinion cylinder at the feed end, and a drive gear is meshed with the output end of the rack and pinion cylinder. The drive gear meshes with two driven gears, and the shafts of the two driven gears are coaxially fixedly connected to a drive support wheel. A cleaning tank is installed inside the cleaning mechanism, and a pump system is installed in the cleaning tank. A nozzle is installed on the side of the cleaning mechanism facing the telescopic placement mechanism, and the nozzle is connected to the pump system. The telescopic placement mechanism includes a first water receiving trough that is connected to the feed end of the cleaning mechanism. A second water receiving trough is slidably installed on the first water receiving trough. Movable brackets are installed at the bottom of both the first and second water receiving troughs. A driven support seat is installed in the second water receiving trough in a V-shape.

[0005] Furthermore, the rack cylinder is not installed on the moving path of the first water receiving tank. This design prevents interference when the first water receiving tank is inserted into the cleaning mechanism.

[0006] Furthermore, the travel range of the telescopic placement mechanism is 1 to 6 meters, a design that can accommodate the placement of most large hydraulic cylinders currently available.

[0007] Furthermore, the cleaning tank is equipped with a level gauge, a design that allows for real-time monitoring and detection of the liquid level, ensuring the normal operation of the equipment.

[0008] Furthermore, the telescopic placement mechanism includes a guide rail installed on the ground, and the movable bracket is slidably mounted on the guide rail. This design allows the movable bracket to move more smoothly, thereby making the sliding match between the first water receiving tank and the second water receiving tank more stable.

[0009] The beneficial effects of using this utility model are as follows: This utility model, with the cooperation of the first and second water receiving tanks, achieves a change in the length between them, thereby changing the distance between the driven support seat and the active support wheel. This allows for the placement of large hydraulic cylinders of different lengths. While being highly adaptable, the variable length of the cleaning mechanism does not impose large requirements on its main body specifications. In other words, the cleaning mechanism does not need to be too large, and its small footprint makes it easier to meet the installation requirements of the site.

[0010] This invention uses a pump system to spray liquid from the nozzle into the cleaning tank, delivering the liquid to the oil cylinder being cleaned through rinsing and agitation. Simultaneously, under the power of the rack and pinion cylinder, two active support wheels rotate synchronously in opposite directions, causing the large oil cylinder placed on them to rotate, ensuring the cleaning effect.

[0012] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example

[0013] like Figures 1-3 As shown, the present invention provides a hydraulic cylinder cleaning machine, which includes a cleaning mechanism 1 and a telescopic placement mechanism 2 connected to the cleaning mechanism 1. The cleaning mechanism 1 is equipped with a rack cylinder 11 at the feed end. The output end of the rack cylinder 11 is meshed with a drive gear 12. The drive gear 12 meshes with two driven gears 13. The shafts of the two driven gears 13 are coaxially fixedly connected to a drive support wheel 14. The cleaning mechanism 1 is equipped with a cleaning box 15. The cleaning box 15 is equipped with a pump system 16. The cleaning mechanism 1 is equipped with a nozzle 17 on the side facing the telescopic placement mechanism 2. The nozzle 17 is connected to the pump system 16. The telescopic placement mechanism 2 includes a first water receiving trough 21 that is connected to the feed end of the cleaning mechanism 1. A second water receiving trough 22 is slidably installed on the first water receiving trough 21. Movable brackets 23 are installed at the bottom of both the first water receiving trough 21 and the second water receiving trough 22. A driven support seat 24 is installed in a V-shape on the second water receiving trough 22.

[0014] In this implementation case, the length of the telescopic placement mechanism 2 is adjusted to adjust the length of the cylinder that needs to be cleaned. After the cylinder is placed, the end of the cylinder is connected to the output end of the nozzle 17. The pump system is then started to complete the cleaning of the cylinder. Specifically, the first water receiving tank 21 and the second water receiving tank 22 are directly moved by the movable support 23. This movement alters the overall length between the two tanks, causing a change in the liquid level. Simultaneously, the position of the second water receiving tank 22 changes, thus changing the position of the driven support 24 mounted thereon. This alters the distance between the driven support 24 and the driving support wheel 14, allowing the corresponding specification of the oil cylinder to be cleaned to be placed on the driven support 24 and the driving support wheel 14. After placement, the second water receiving tank 21 can be pushed slightly to allow the cylinder placed on it to... When the end of the hydraulic cylinder is close to or completely encloses the nozzle 17, the pump system starts. It should be noted that the pump system is a common liquid supply system that can be purchased directly, without specific requirements. The liquid in the cleaning tank 15 is sprayed out from the nozzle 17 at the angle shown in the figure, impacting the inside of the hydraulic cylinder in a downward and upward manner, so as to achieve the purpose of flushing the impurities inside the hydraulic cylinder. The impurities impacted and flowing with the liquid flow onto the first water receiving tank 21 or the second water receiving tank 22, and further flow into the cleaning tank 15 to achieve circulation. It should be noted that the presence of a filter mechanism inside the cleaning tank 15 or in the pump system 16 is a conventional technology that can be anticipated and installed by those skilled in the art. Example

[0015] like Figure 1 As shown, the rack cylinder 11 is not installed on the moving path of the first water receiving tank 21.

[0016] In this implementation case, through the rational planning of the overall structure of the equipment, the rack and pinion cylinder 11 is installed in an area that will not intersect with the movement trajectory of the first water receiving tank 21. When the first water receiving tank 21 is inserted into the cleaning mechanism 1 to collect water, since the rack and pinion cylinder 11 is not on its movement path, interference and collision between the two can be completely avoided. This effectively ensures that the first water receiving tank 21 can complete the insertion action smoothly and without obstruction, ensuring the stability and reliability of wastewater collection during the cleaning process, and preventing water collection failure or equipment damage due to interference. On the other hand, avoiding interference can reduce mechanical wear during equipment operation, extend the overall service life of the equipment, reduce maintenance costs, and improve the safety of equipment operation, reduce potential accident risks, and make the operation of the entire cylinder cleaning machine more efficient and stable. Example

[0017] like Figure 1 As shown, the travel range of the telescopic placement mechanism 2 is 1 to 6 meters.

[0018] In this implementation case, the first water receiving tank 21 and the second water receiving tank 22 are structured as a multi-level nested telescopic frame. The frames are connected by slide rails and locking components to achieve smooth extension and retraction. When placing large hydraulic cylinders of different lengths, the extension length of the telescopic frame can be adjusted manually or electrically. For short large hydraulic cylinders of about 1 meter, only the innermost frame needs to be extended to meet the placement requirements. For extra-large hydraulic cylinders of 6 meters in length, all frames are fully extended to ensure the stability of the hydraulic cylinder during placement. The travel range of 1 to 6 meters can cover the length specifications of most large hydraulic cylinders in the current industrial field. There is no need to equip separate placement mechanisms for hydraulic cylinders of different sizes, which greatly improves the versatility of the equipment. The telescopic adjustment can quickly match the length of the hydraulic cylinder, eliminating the disassembly and replacement steps of the traditional fixed placement frame and shortening the preparation time before cleaning the hydraulic cylinder. When not in use, the frame can be retracted to the minimum state to reduce the floor space occupied when the equipment is idle, which is especially suitable for production workshops with limited space. Example

[0019] like Figure 1 As shown, the cleaning tank 15 is equipped with a level gauge 18.

[0020] In this implementation, the level gauge 18 is fixed to the side wall or top of the cleaning tank 15 using a side-mounted or top-mounted structure. Its detection probe or sensing element is in direct contact with the cleaning fluid inside the tank. It collects liquid level data in real time through the principle of communicating vessels or electronic sensing technology, such as ultrasonic waves or float sensors, and converts the data into a visual scale display or transmits an electrical signal to the display screen of the equipment control panel. Furthermore, the side-mounted glass tube level gauge can visually display the liquid level height through the communication interface at the bottom and middle of the cleaning tank 15; the electronic level gauge can dynamically display the liquid level value on the control panel. The system has preset high and low liquid level thresholds, allowing operators to monitor the remaining amount of cleaning fluid in the cleaning tank 15 in real time via the level gauge 18. This eliminates the need for manual opening of the lid, reducing operational steps and preventing cleaning fluid splashing. Furthermore, when the liquid level falls below the preset threshold, the level gauge 18 can trigger an alarm or automatically shut down the machine to prevent damage to the cleaning mechanism due to insufficient cleaning fluid, while also preventing excessive liquid levels from causing cleaning fluid overflow and waste or contamination of the equipment. Based on the real-time data from the level gauge 18, the amount of cleaning fluid replenished can be precisely controlled, avoiding resource waste caused by over-addition and reducing operating costs. Example

[0021] like Figure 1 , Figure 2 As shown, the telescopic placement mechanism 2 includes a guide rail 25 installed on the ground, and a movable bracket 23 slidably installed on the guide rail 25.

[0022] In this implementation, the guide rail 25 is made of high-strength alloy material and is fixed to the ground with expansion bolts. Its length is adapted to the maximum stroke of the telescopic placement mechanism 2. The surface is precision ground to ensure flatness. The bottom of the movable bracket 23 is equipped with a slider or roller that matches the guide rail 25. The inner side of the slider is provided with a wear-resistant liner, and the outer ring of the roller is made of high-elasticity rubber material. Both of them form a tight fit with the guide rail 25. When the movable bracket 23 needs to move, the slider or roller is driven by a drive device, such as a gear and rack transmission or a hydraulic cylinder, to slide back and forth along the guide rail 25. Limit blocks are provided at both ends of the guide rail 25 to prevent the movable bracket 23 from sliding off the track. Furthermore, it can also be pushed manually. The rigid structure of the guide rail 25 provides precise guiding constraints for the movable bracket 23, preventing it from sliding off the track during movement. Even when there is lateral deviation or vertical swaying, especially when bearing the weight of a large hydraulic cylinder, the moving bracket 23 can be ensured to run stably along a straight line. Because the moving bracket 23 slides smoothly, the first water receiving groove 21 and the second water receiving groove 22 installed on it can always maintain accurate alignment during the extension and retraction docking process, reducing gaps or misalignment caused by shaking and ensuring the sealing when receiving water. The surface contact design between the slider and the guide rail 25 or the line contact design between the roller and the guide rail 25 disperses friction and reduces local stress, extending the service life of the moving bracket 23 and the guide rail 25. Moreover, the installation of the guide rail 25 allows the guide rail 25 to compensate for errors through its own flatness even if there are slight unevenness in the ground, ensuring that the moving bracket 23 remains stable under heavy load or high frequency movement, thus improving the overall operational reliability of the equipment.

[0023] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
