Description

Technical Field

[0001] This application relates to the field of disassembly and assembly machine technology, and in particular to hydraulic disassembly and assembly machines. Background Technology

[0002] With the rapid development of the heavy-haul railway industry, the number of high-power electric locomotives, especially diesel locomotives, is increasing year by year. The maintenance quality of locomotives is directly related to the safe and reliable operation of trains. Among them, the diesel engine, as the core power component of diesel locomotives, has extremely strict requirements for the disassembly and assembly process of its cylinder head nuts. It is essential to ensure that the tightening torque of each nut precisely matches the technical standards. Otherwise, it may lead to serious failures such as cylinder block seal failure, diesel engine overheating, or even cylinder head deformation, resulting in significant economic losses and safety hazards.

[0003] Traditional disassembly and assembly operations rely entirely on manual labor, using suspended hydraulic tools without fixed supports. During operation, one or two operators must hold the tool up by hand and visually align it with the nut before disassembly or assembly. When operating manually in the air, the coaxiality of the tool and the nut is prone to deviation, causing wear on the nut's edges and corners, and even risks such as tool jamming and hydraulic system overload. Utility Model Content

[0035] The light sensor is communicatively connected to the auxiliary lighting component.

[0036] According to the hydraulic disassembly and assembly machine of this application embodiment, the frame and balance suspension provide a stable support foundation for the entire disassembly and assembly operation.

This effectively solves the problem of easy deviation in the coaxiality of tools and nuts in traditional manual operation. Attached Figure Description

[0056] See Figure 1 , Figure 2 as well as Figure 3This application provides an embodiment of a hydraulic assembly / disassembly machine, which includes a frame 100, an assembly / disassembly mechanism 200, a hydraulic drive mechanism, and a balance suspension 700. The assembly / disassembly mechanism 200 includes a plurality of assembly / disassembly units 210 mounted on the frame 100, which are used for assembling and disassembling nuts. The hydraulic drive mechanism includes a hydraulic source 300 and a hydraulic motor 400 connected to the hydraulic source 300, which is driven by the assembly / disassembly units 210. Figure 4 The balance suspension 700 includes a level detector 710 and at least four hydraulic telescopic rods 720. The level detector is set on the side wall of the frame 100 and is used to detect the tilt angle of the frame 100. The hydraulic telescopic rods 720 are installed at the bottom of the frame 100 and are used to support the frame 100. The level detector 710 and the hydraulic telescopic rods 720 are communicatively connected.

[0057] According to the hydraulic disassembly and assembly machine of this application embodiment, the frame 100 and the balance suspension 700 provide a stable support foundation for the entire disassembly and assembly operation. All disassembly and assembly units 210 are installed on the frame 100, replacing the traditional suspended operation without fixed supports. This avoids tool displacement caused by hand shaking when manually lifting tools, fundamentally reducing coaxiality deviation caused by unstable support. Secondly, the level detector 710 of the balance suspension 700 can monitor the tilt angle of the frame 100 in real time. When the frame 100 is detected to be tilted, it transmits a signal to the hydraulic telescopic rod 720, which adjusts the level of the frame 100 through telescopic adjustment. The setting of at least four hydraulic telescopic rods 720 can adjust the posture of the frame 100 from multiple support points to ensure that the frame 100 is always in a horizontal state. This ensures that the axis of the disassembly and assembly unit 210 installed on the frame 100 is parallel to the axis of the nut to be disassembled or assembled, avoiding oblique alignment of the tool and nut due to the tilt of the frame 100, and ensuring the coaxiality of the two. It effectively solves the problem of misalignment between tools and nuts in traditional manual operations.

[0058] Specifically, the hydraulic power source 300 provides high-pressure hydraulic fluid, typically 1070 MPa, to drive the hydraulic motor 400. The disassembly / assembly unit 210 is configured as a hydraulic torque wrench or hydraulic tensioner to achieve disassembly / assembly. The hydraulic drive mechanism is small in size, has high torque, adjustable pressure range, reliable performance, and is easy to operate. The hydraulic power source 300 connects to a flow divider valve or a flow divider-combiner valve, distributing the fluid to each disassembly / assembly unit 210 to ensure synchronized operation. The hydraulic power source 300 connects to each disassembly / assembly unit 210 via flow divider valves or flow divider-combiner valves, which precisely distribute high-pressure hydraulic fluid to the hydraulic motor 400 of each disassembly / assembly unit 210 according to a preset ratio. When the equipment is configured with six disassembly / assembly units 210, the valve assembly ensures consistent flow rate and pressure of the hydraulic fluid flowing into each motor, synchronizing the rotational speed and torque output of all disassembly / assembly units 210. This ensures consistent alignment rhythm between multiple disassembly / assembly units 210 and their corresponding nuts, reducing coaxiality deviations caused by some units being ahead or behind.

[0059] The level detector 710 monitors the tilt angle of the frame 100 in real time to ensure that the frame 100 is in a level state. The hydraulic telescopic rod 720, as a support component, can automatically extend and retract according to the signal from the level detector 710. When a tilt is detected on one side of the frame 100, the hydraulic telescopic rod 720 on the corresponding side extends, and the one on the opposite side shortens until the frame 100 is level. Through this setup, the stability of the frame 100's level state ensures that the axis of the assembly / disassembly unit 210 installed on it remains parallel to the axis of the nut, avoiding misalignment caused by the tilt of the frame 100 and guaranteeing coaxiality from a fundamental level.

[0060] See Figure 3 In some embodiments, the hydraulic source 300 includes a hydraulic pump station 310, a connecting pipeline 320, and a pressure regulating component 330. The hydraulic pump station 310 includes a hydraulic oil tank. The connecting pipeline 320 connects the hydraulic pump station 310 and the hydraulic motor 400. The pressure regulating component 330 is disposed on the connecting pipeline 320 and is used to regulate the pressure of the hydraulic oil supplied by the hydraulic pump station 310 to the hydraulic motor 400.

[0061] The hydraulic pump station 310 serves as a power source, storing hydraulic oil in its included hydraulic oil tank and pressurizing it to form high-pressure hydraulic fluid. The connecting pipeline 320 acts as a transmission channel, delivering the high-pressure hydraulic fluid output from the hydraulic pump station 310 to the hydraulic motor 400, providing power to the hydraulic motor 400. Since the output torque of the hydraulic motor 400 is directly related to the hydraulic oil pressure, the pressure regulating component 330 can flexibly adjust the hydraulic oil pressure delivered from the hydraulic pump station 310 to the hydraulic motor 400, thereby controlling the output torque of the hydraulic motor 400 driving the disassembly and assembly unit 210. This ensures that the torque strictly matches the process requirements when disassembling and assembling nuts, avoiding excessive torque leading to nut edge wear, tool jamming, or hydraulic system overload, or insufficient torque resulting in substandard disassembly and assembly, thus improving the safety and reliability of the operation.

[0062] In some embodiments, the pressure regulating assembly 330 includes a pressure regulating valve 331 and a flow control valve, wherein the pressure regulating valve 331 is disposed in the connecting pipeline 320; and the flow control valve 332 is disposed in the connecting pipeline 320. The torque of the hydraulic drive mechanism is proportional to the hydraulic pressure, and the system pressure is adjusted by the pressure regulating assembly 330 to control the output torque.

[0063] The pressure regulating valve 331 directly controls the pressure of the hydraulic oil in the connecting pipeline 320. Since the torque of the hydraulic drive mechanism is proportional to the hydraulic pressure, adjusting the pressure regulating valve 331 linearly changes the pressure value of the hydraulic system, thereby precisely controlling the output torque of the hydraulic motor 400 driving the disassembly and assembly unit 210. For example, for cylinder head nuts of different specifications, the pressure regulating valve 331 can be used to preset the corresponding pressure, ensuring that the torque strictly matches the process requirements and avoiding the problem of excessive or insufficient torque caused by uneven force application in traditional manual operation. The flow control valve 332 is located in the connecting pipeline 320 and is used to regulate the flow rate of the hydraulic oil. Stable flow rate ensures the uniformity of the rotation speed of the hydraulic motor 400, avoiding sudden changes in torque output due to flow fluctuations, and indirectly improving the stability of torque control. When multiple disassembly and assembly units 210 operate synchronously, the flow control valve 332, in conjunction with the flow divider / flow combiner valve, ensures consistent oil flow in each unit, further guaranteeing torque consistency during synchronous operation. In summary, the pressure regulating component 330 achieves precise and stable control of the output torque of the hydraulic drive mechanism through dual regulation of pressure and flow. From the perspective of power output, it solves the drawbacks of large torque deviation and reliance on human experience in traditional manual operation, and improves the accuracy and reliability of nut assembly and disassembly.

[0064] In some embodiments, the pressure regulating assembly 330 further includes a mechanical limiter or a relief valve to limit the maximum torque and prevent overload. The mechanical limiter, through mechanical structures such as limit blocks or locking pins, limits the maximum rotation angle or stroke of the disassembly / assembly unit 210. When the torque reaches a preset maximum value, the mechanical structure forcibly terminates the action, physically preventing the torque from continuously increasing. The relief valve is a pressure protection element in the hydraulic system. When the hydraulic oil pressure in the connecting pipeline 320 exceeds a set threshold, the relief valve automatically opens, releasing some high-pressure oil back to the hydraulic oil tank, maintaining the system pressure within a safe range, and indirectly limiting the output torque of the hydraulic motor 400 driving the disassembly / assembly unit 210. The mechanical limiter and the relief valve work together to achieve the maximum torque limiting function through different principles. Specifically, the mechanical limiter is a mechanical hard limiter with a direct response; the relief valve is a hydraulic pressure soft limiter, adaptable to dynamic pressure fluctuations. This design effectively prevents torque overload caused by operational errors or sudden working conditions, avoiding problems such as severe wear of nut edges, tool jamming and damage, and hydraulic system overpressure failure caused by the inability to accurately control force in traditional manual operation, thus further improving the safety and reliability of equipment operation.

[0065] In some embodiments, the pressure regulating assembly 330 further includes a reversing valve, which enables forward and reverse rotation for convenient disassembly and assembly switching. The reversing valve is located in the connecting pipeline 320 and controls the rotation direction of the hydraulic motor 400 by changing the flow direction of the hydraulic oil in the pipeline. When the reversing valve switches to the forward oil circuit, the hydraulic oil drives the hydraulic motor 400 to rotate forward, causing the disassembly and assembly unit 210 to tighten the nut; when switched to the reverse oil circuit, the hydraulic motor 400 rotates in the reverse direction, disassembling the nut. The forward and reverse rotation switching achieved by the reversing valve replaces the cumbersome process of manually flipping tools or adjusting the grip direction in traditional manual operations. This not only simplifies the switching steps of disassembly and assembly operations and reduces operation time, but also avoids misalignment between the tool and the nut caused by manual adjustment of direction, ensuring that the disassembly and assembly unit 210 and the nut remain precisely aligned during tightening and disassembly switching, further improving work efficiency and accuracy.

[0066] See Figure 3In some embodiments, the hydraulic source 300 further includes a first temperature sensor 340, which is disposed inside the hydraulic oil tank to detect the temperature of the hydraulic oil inside the tank. The first temperature sensor 340, installed inside the hydraulic oil tank, can detect the temperature of the hydraulic oil in real time and directly. The temperature of the hydraulic oil directly affects its viscosity, fluidity, and the working performance of the hydraulic system. Excessive temperature may cause the hydraulic oil viscosity to decrease, weaken its lubrication performance, accelerate the wear of components such as the hydraulic pump and hydraulic motor 400, and even lead to oil deterioration and seal aging and failure; excessively low temperature may increase the oil viscosity, leading to increased system pressure loss, reduced power transmission efficiency, and affecting the torque output stability of the disassembly and assembly unit 210.

[0067] Real-time monitoring of hydraulic oil temperature by the first temperature sensor 340 provides data for subsequent temperature control, ensuring that the hydraulic oil operates within a suitable temperature range, thereby guaranteeing the stable operation of the hydraulic drive mechanism, indirectly improving the reliability and accuracy of the disassembly and assembly unit 210, and avoiding equipment failure or operational deviation caused by abnormal oil temperature.

[0068] See Figure 4 In some embodiments, the hydraulic source 300 further includes a second temperature sensor 350, which is mounted on the frame 100 and used to detect the ambient temperature of the frame 100. The second temperature sensor 350 is mounted on the frame 100 to detect the ambient temperature of the equipment in real time. Ambient temperature is an important external factor affecting the operating state of the hydraulic system. In low-temperature environments, not only will the viscosity of the hydraulic oil itself increase, but excessively low ambient temperatures may also cause changes in the physical properties of hydraulic pipelines, seals, and other components, affecting oil transmission efficiency. In high-temperature environments, the ambient temperature and hydraulic oil temperature easily create a superimposed effect, accelerating oil deterioration and component wear.

[0069] The ambient temperature is detected by the second temperature sensor 350, which can be linked with the hydraulic oil temperature detected by the first temperature sensor 340 for reference: when the ambient temperature is too high or too low, the control system can combine the data of both to predict the trend of hydraulic oil temperature change in advance.

[0070] See Figure 3 In some embodiments, the hydraulic source 300 further includes a cooling assembly 360 and a heating assembly 370. The cooling assembly 360 is disposed in the hydraulic oil tank and is used to cool the hydraulic oil in the hydraulic oil tank; the heating assembly 370 is disposed in the hydraulic oil tank and is used to heat the hydraulic oil in the hydraulic oil tank.

[0071] The cooling component 360 is installed in the hydraulic oil tank. When the first temperature sensor 340 detects that the hydraulic oil temperature is too high, such as exceeding the upper limit of the suitable working temperature of the hydraulic system, the cooling component 360 is activated to reduce the hydraulic oil temperature through heat dissipation, air cooling or liquid cooling, so as to avoid problems such as viscosity reduction, weakened lubrication performance and aging of seals due to overheating of the oil. It also prevents core components such as hydraulic pump and hydraulic motor 400 from being worn out due to high temperature, and ensures stable power output of the hydraulic drive mechanism.

[0072] The heating component 370 is also located in the hydraulic oil tank. When the first temperature sensor 340 detects that the hydraulic oil temperature is too low, such as below the lower limit of the suitable working temperature, the heating component 370 is activated to heat the hydraulic oil, reduce the viscosity of the oil, improve its fluidity, and avoid problems such as increased system pressure loss and reduced power transmission efficiency caused by excessively thick oil. This ensures that the hydraulic motor 400 and the disassembly and assembly unit 210 can output stable torque to meet the accuracy requirements for nut disassembly and assembly.

[0073] In some embodiments, the heating component 370 typically employs an electric heating element, such as an armored heating tube, installed at the bottom or side wall of the hydraulic oil tank. It directly heats the hydraulic oil within the tank by converting electrical energy into heat. When the first temperature sensor 340 detects that the hydraulic oil temperature is below a low-temperature threshold, the electric heating element is energized. Its power can be set according to the tank capacity. Through heat conduction, the hydraulic oil temperature is gradually increased to a suitable operating temperature, avoiding the problems of increased oil viscosity and poor fluidity caused by low temperatures.

[0074] The cooling system 360 uses an air-cooled cooler, integrated into the oil outlet or return line of the hydraulic oil tank, and consists of a cooling fan and a finned heat sink. When the hydraulic oil temperature exceeds the high-temperature threshold, the cooler starts, the high-temperature hydraulic oil flows through the heat sink, and the fan blows heat away from the fins, bringing the oil temperature down below the high-temperature threshold.

[0075] Through the above settings, the cooling component 360 and the heating component 370, together with the data feedback from the first temperature sensor 340 and the second temperature sensor 350, form a closed-loop control mechanism for hydraulic oil temperature, ensuring that the hydraulic oil is always within a suitable operating temperature range. This guarantees the reliable operation of the hydraulic power source 300 and the entire hydraulic drive mechanism under different environmental conditions, and indirectly improves the stability and accuracy of disassembly and assembly operations.

[0076] See Figure 4 In some embodiments, the balance suspension 700 further includes pressure sensors 730. Four pressure sensors 730 are provided and are respectively installed at the bottom of the hydraulic telescopic rods 720. The pressure sensors 730 are used to detect the force value of each hydraulic telescopic rod 720. The pressure sensors 730 and the hydraulic telescopic rods 720 are communicatively connected.

[0077] Specifically, four pressure sensors 730 are respectively installed at the bottom of the four hydraulic telescopic rods 720, which can detect the force value borne by each hydraulic telescopic rod 720 in real time. Since the pressure sensors 730 are communicatively connected to the hydraulic telescopic rods 720, the force data can be transmitted to the control system in real time, forming a dynamic monitoring of the support status of the frame 100. When the force difference between any two hydraulic telescopic rods 720 exceeds a preset threshold, it indicates that there is uneven force on the frame 100, which may be caused by uneven ground, local load deviation, etc. The control system will drive the corresponding hydraulic telescopic rod 720 to adjust its extension and retraction according to the feedback signal from the pressure sensors 730. For example, the telescopic rod with excessive force is appropriately shortened, and the telescopic rod with insufficient force is appropriately lengthened, until the force on the four telescopic rods tends to be balanced.

[0078] This force monitoring and adjustment mechanism based on pressure sensor 730 complements the tilt angle monitoring of level detector 710, ensuring that the frame 100 is level and that the force on each support point is uniform, avoiding deformation or vibration of the frame 100 due to local overload, thereby ensuring the alignment stability of the disassembly unit 210 and the nut installed on the frame 100, reducing the risk of coaxiality deviation from the foundation level, and improving the overall reliability of the equipment operation.

[0079] See Figure 5 In some embodiments, the hydraulic disassembly and assembly machine further includes an industrial camera 800 and a light source 810. The industrial camera 800 is mounted on the frame 100, with its lens facing the nut to be disassembled. The light source 810 is mounted on the frame 100 and positioned close to the industrial camera 800. The cooperation between the industrial camera 800 and the light source 810 allows the industrial camera 800, mounted on the frame 100 with its lens facing the nut, to capture real-time image information of the nut. This information is used to accurately identify the nut's position, outline, and other features, providing a visual reference for the alignment of the disassembly and assembly unit 210 with the nut, thus improving alignment accuracy. The light source 810, positioned close to the industrial camera 800, provides supplemental lighting to the shooting area, preventing image blurring due to insufficient ambient light and ensuring that the industrial camera 800 can clearly capture nut details, guaranteeing the effectiveness of visual recognition.

[0080] In some embodiments, the hydraulic disassembly and assembly machine further includes a light sensor 900, which is mounted on the frame 100 and used to collect the light intensity signal of the working environment; wherein, the light sensor 900 is communicatively connected to the light source 810. The light sensor 900, mounted on the frame 100, can collect the light intensity of the working environment in real time. Because it is communicatively connected to the light source 810, when it detects that the ambient light is too strong or too weak, it can trigger the light source 810 to automatically adjust its brightness; for example, increasing the brightness of the light source when the ambient light is weak and decreasing the brightness of the light source when the ambient light is strong, so that the industrial camera 800 always works under suitable lighting conditions, ensuring the stability of image acquisition quality, and thus ensuring more accurate and reliable image-based alignment adjustments.

[0081] In some embodiments, the hydraulic assembly / disassembly machine further includes an auxiliary lighting element 820, which is mounted on the frame 100 and positioned close to the light source 810; wherein, the light sensor 900 is communicatively connected to the auxiliary lighting element 820. Specifically, the auxiliary lighting element 820 is ring-shaped and positioned around the industrial camera 800 and the light source 810, forming a surround lighting effect on the work area. It is communicatively connected to the light sensor 900 and can dynamically adjust its brightness according to the ambient light intensity signal collected by the light sensor 900: when the ambient light is too dim, such as when the light sensor 900 detects a value below a preset threshold, and the light source 810 alone is insufficient, the auxiliary lighting element 820 automatically turns on and enhances the illumination, providing uniform light to the nut area from multiple angles through its ring structure, eliminating shadow interference; when the ambient light is sufficient, the auxiliary lighting element 820 automatically turns off or reduces its brightness to avoid overexposure of the image due to strong light.

[0082] The above settings further enhance the light stability of the shooting environment of the industrial camera 800, ensuring that the image details of the nut can still be clearly captured under complex lighting conditions, such as uneven brightness in some parts of the workshop. This provides more reliable visual data for accurate alignment and status recognition, and indirectly ensures the coaxiality accuracy between the assembly / disassembly unit 210 and the nut.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
