Description

Technical Field

[0001] The present invention belongs to the technical field related to chain testing devices, and more specifically, relates to a comprehensive detection device for chain durability testing. Background Art

[0002] In industrial production, chains must withstand enormous tension, friction, and long cycles, making them prone to wear, fatigue, and elongation. If a chain fails during operation, it can cause equipment downtime, impact production progress, and even lead to safety accidents. To ensure that chains can operate stably and reliably under various complex working conditions, rigorous chain testing is required during the production process. However, existing chain testing devices have the following drawbacks: In existing technology, long-term chain testing in chain testing devices produces sludge, which is mixed with impurities such as dust and metal (grinding) chips, causing abrasive wear on the chain links, pins, rollers, and other parts. During chain operation, these impurities will continuously scratch the chain surface like sandpaper, accelerating the wear of chain components and shortening the chain's service life. This will also cause deviations in test results, making it impossible to accurately assess the chain's actual performance. The sludge will also increase the resistance between the chain's moving parts, resulting in uneven load during chain operation. This may cause chain jitter, tooth skipping, and other problems, affecting the normal operation of the chain and reducing the accuracy and reliability of the test. In addition, the sludge may also reduce the chain's lubrication performance, further exacerbating chain wear and unstable operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a comprehensive chain durability testing device equipped with a high-pressure nozzle. Conventional cooling nozzles often use a conventional spray method, resulting in poor cooling oil atomization and difficulty forming a uniform cooling film on the chain surface. The present invention's high-pressure nozzle utilizes a unique atomizing nozzle structure. Through its built-in fine flow channel and unique nozzle shape, it can spray cooling oil delivered by an adsorption water pump onto the chain surface in a fine, high-speed mist. Furthermore, the nozzle is positioned above the chain and perpendicular to it, achieving precise cooling at locations prone to generating significant frictional heat, such as links and pins. Compared to the arbitrary spray angles of conventional nozzles, this vertical arrangement significantly enhances the targeted and effective cooling. Furthermore, this layout aligns with the operating logic of an oil collection device, allowing the sprayed cooling oil to carry sludge with it as it falls, facilitating subsequent sludge cleaning and cooling oil collection and filtration by the oil collection device. This seamlessly integrates the cooling and cleaning steps of the entire testing process, forming an efficient closed-loop operation.

[0016] The present invention provides a comprehensive detection device for chain durability testing. The cleaning cylinder device initially intercepts sludge through holes on the surface of the outer cleaning cylinder, cooperates with a curved scraper device to achieve deep cleaning, and simultaneously collaborates with an adsorption water pump to complete cooling oil circulation. Its internal gear transmission causes the inner and outer layers to rotate in opposite directions, enhancing sludge capture. The rotating blades and curved scraper efficiently scrape and separate the sludge, and the telescopic motor can intelligently adjust the cleaning force according to the amount of sludge. This device effectively prevents sludge from interfering with chain operation and prevents chain performance degradation due to high temperatures, significantly improving cleaning efficiency, ensuring a stable chain durability test process and reliable data, and ensuring that the cleaning component maintains efficient operation under different operating conditions.

[0017] The present invention provides a comprehensive detection device for chain durability testing. The collecting tube is provided with a specially designed arc-shaped scraper inside, which forms an efficient cooperative mechanism with the cleaning tube device. When the cleaning tube device transports the sludge to the collecting tube area, the arc-shaped scraper deflects around the fixed axis under the action of friction, and cooperates with the elastic restoring force of the reset spring to repeatedly shear and squeeze the sludge, which can completely separate the sludge from the surface of the cleaning tube device, achieve deep cleaning of the sludge on the chain surface, and avoid residual oil stains affecting the test accuracy. At the same time, it can effectively prevent the accumulation of sludge in the test area, avoid problems such as chain jamming and poor operation, ensure the stable operation of the chain during the durability test, highly restore the real working conditions, and greatly improve the reliability of the test results.

When any parameter monitored by the environmental monitoring module exceeds the preset threshold, the central controller controls the drive motor 20 to reduce the speed and increases the suction force of the adsorption water pump 50, and controls the telescopic motor 54 to drive the mobile scraper 45 to strengthen the cleaning force of the sludge, thereby realizing intelligent adjustment of the test environment and efficient treatment of oil pollution.

[0035] Specific use of the present invention: When using the present invention to conduct a chain durability test, first place the entire device stably in the test area of ​​the chain workshop. Subsequently, by adjusting the fastening bolts on the auxiliary shaft 23, the auxiliary shaft 23 is given lateral freedom of movement, leaving adjustment space for chain installation. Next, the chain to be tested is laid on the outside of the auxiliary shaft 23 and the drive shaft 21, and the chain is appropriately tightened by utilizing the adjustable characteristics of the auxiliary shaft 23 to ensure that it maintains a constant tension during operation, avoiding the test results being affected by slack or overtightening. After completing the chain installation and positioning, retighten the bolts on the auxiliary shaft 23 to fix it in its current position, thus completing the basic preparations before the test.

[0036] Start the test process and turn on the drive motor 20 and the adsorption water pump 50 simultaneously. The output shaft of the drive motor 20 is connected to the drive shaft 21. After power is turned on, the drive motor 20 drives the drive shaft 21 to rotate at a uniform speed, thereby driving the chain 24 to continuously circulate between the auxiliary shaft 23 and the drive shaft 21, simulating the operating state of the chain under actual working conditions and realizing the core function of the durability test. At the same time, the adsorption water pump 50 inside the inner cylinder 34 starts to operate. It generates suction through the built-in centrifugal impeller, driving the adsorption head 40 to continuously extract the cooling oil stored in the inner cylinder 34. The cooling oil enters the internal flow channel of the cleaning cylinder device 30 through the adsorption head 40, and under the action of the circulation system, it is transported along the conduit path to the high-pressure nozzle 31 at the end of the cleaning cylinder device 30. The high-pressure nozzle 31 adopts a special atomizing nozzle design, which can spray the cooling oil in a fine mist onto the surface of the chain 24, forming a uniform cooling cover layer. This effectively reduces the heat generated by the chain during high-speed operation, prevents the degradation of chain material performance due to excessive temperature, and ensures the stability of the test process and the reliability of the data.

[0037] As the chain 24 continues to operate for a long time, the cooling oil on its surface constantly comes into contact with and mixes with the dust and impurities in the workshop environment, gradually forming a viscous sludge. At this time, the oil collection device 14 begins to work. After the transmission motor 27 inside the device is powered on, the main shaft screw at its output end drives the rotating threaded rod 26 to rotate synchronously. The rotating threaded rod 26 adopts a trapezoidal thread design, and forms a spiral transmission pair with the nut structure inside the moving block 28. When the rotating threaded rod 26 rotates, the moving block 28 will make precise lateral movements along the axial direction of the threaded rod. The end of the moving block 28 is fixedly connected to the oil cleaning assembly 29, so under the drive of the moving block 28, the oil cleaning assembly 29 as a whole performs lateral reciprocating motion along the bottom of the collection chamber 16.

[0038] As the core component of the oil cleaning assembly 29, the cleaning cylinder device 30 performs the dual functions of collecting and cleaning sludge during its movement. The cleaning cylinder device 30 comprises a double-layer structure consisting of an outer cleaning cylinder 32 and an inner cylinder 34. The surface of the outer cleaning cylinder 32 is evenly distributed with honeycomb-shaped through-holes. The diameter of these through-holes has been precisely designed to ensure smooth passage of cooling oil while providing a preliminary barrier and pressure against the sludge. When the cleaning cylinder device 30 contacts the sludge at the bottom of the collection chamber 16, the through-holes of the outer cleaning cylinder 32 first contact the surface of the sludge. Under the rolling pressure of the cleaning cylinder device 30, some of the sludge is squeezed into the annular gap between the outer cleaning cylinder 32 and the inner cylinder 34. Simultaneously, the rolling motion of the cleaning cylinder device 30 drives the second gear 39 and the first gear 38 to rotate sequentially through the gear transmission mechanism. The first gear 38 is fixedly connected to the inner cylinder 34 via the connecting shaft 37. Therefore, under the action of the gear transmission, the inner cylinder 34 and the outer cleaning cylinder 32 form a counter-rotational motion. This relative rotation can further enhance the sludge grabbing and conveying effect.

[0039] The rotating blades 46, located within the cleaning cylinder assembly 30, are key components for achieving the sludge scraping function. Made of an elastic, wear-resistant material, the rotating blades 46 feature a wavy scraping edge. Connected to the isolation plate 35 via a tension spring 44, this structure ensures that the rotating blades 46 maintain a close fit against the inner wall of the outer cleaning cylinder 32. As the cleaning cylinder assembly 30 rolls, the rotating blades 46, driven by centrifugal force and the tension spring 44, move in a circular motion against the inner wall of the outer cleaning cylinder 32. Their wavy edges gradually scrape off any sludge adhering to the inner wall. Driven by the rotation of the cleaning cylinder assembly 30, the scraped sludge moves along the annular gap toward the collection cylinder 55.

[0040] The curved scrapers 42 installed within the collection barrel 55 further collect and separate the sludge. These scrapers 42 are hinged to the inner wall of the collection chamber 47 via a fixed shaft 43. A return spring is mounted on the fixed shaft 43, allowing them to oscillate elastically within a certain range. The surface of the scrapers 42 has undergone a special hardening treatment for excellent wear resistance, and their curved profile perfectly matches the outer surface of the cleaning barrel assembly 30. When the cleaning barrel assembly 30 transports sludge into the collection barrel 55, the lowest scraper 42 first contacts the sludge. Friction causes the scraper 42 to deflect around the fixed shaft 43, compressing the return spring. As the cleaning barrel assembly 30 continues to rotate, subsequent scrapers 42 successively contact the sludge, creating a continuous shearing action. The elastic restoring force of the return spring ensures that the scrapers 42 quickly return to their original position after each contact, repeatedly shearing and squeezing the sludge, completely separating it from the surface of the cleaning barrel assembly 30 and ultimately dropping it to the bottom of the collection chamber 47 for centralized collection.

[0041] Furthermore, a telescopic motor 54, mounted outside the isolation plate 35, automatically adjusts the retraction and extension distance of the movable scraper 45 based on the amount of sludge accumulation. When the system detects a high level of sludge, the telescopic motor 54 extends the push rod, driving the movable scraper 45 deeper into the gap between the cleaning tube assembly 30 and the inner cylinder 34, increasing the scraping force against the sludge. Conversely, when the amount of sludge is low, the telescopic motor 54 shortens the push rod, reducing friction between the scraper and the tube, thereby lowering energy consumption. This intelligent adjustment mechanism ensures that the oil cleaning assembly 29 maintains efficient cleaning performance under varying operating conditions.

Many modifications and variations will be apparent to those skilled in the art.
