[0022] like Figure 1-2 As shown, a multifunctional large-scale shaft pin safety installation device includes a mechanism chassis 1, and a guardrail is installed on the outer periphery of the mechanism chassis 1. The guardrail can set an effective barrier around the equipment or on the edge of the working platform to prevent the installers from accidentally slipping or tripping. At the same time, it can also prevent the personnel from colliding with the sharp edges and protruding parts of the equipment during walking or operation, thereby avoiding casualties. A translation rack 4 is symmetrically installed on the upper end surface of the mechanism chassis 1, and a translation base 6 is installed above the mechanism chassis 1. A plurality of translation hydraulic gears 5 meshing with the translation rack 4 are symmetrically installed at the lower end of the translation base 6, and the translation hydraulic gear 5 is driven by a hydraulic unit 7 installed on the translation base 6. The translation hydraulic gear 5 is driven to rotate by the hydraulic unit 7 to move on the translation rack 4 meshing with it, so as to meet the left and right movement of the translation base 6.

[0023] A lifting bracket 8 is installed on the upper end of the translation base 6, and an axle pin mounting tray 10 is installed on the lifting bracket 8 through a lifting mechanism. The lifting mechanism includes a lifting rack 11 symmetrically installed on the left and right sides of the lifting bracket 8, and the lifting rack 11 is meshed with a lifting hydraulic gear 9, and the lifting hydraulic gear 9 is installed on the axle pin mounting tray 10. The lifting hydraulic gear 9 moves up and down along the lifting rack 11 under the driving action of the hydraulic unit 7, satisfying the up and down movement of the axle pin mounting tray 10.

[0024] In short, in actual production, the pin and the parts that match it will inevitably have dimensional errors during the manufacturing process. By making the left and right and height adjustable, these errors can be compensated during installation, so that the pin can be accurately installed in the predetermined position, ensuring good matching with other parts such as bearings and sleeves, and avoiding installation difficulties or poor matching problems caused by dimensional deviations. In addition, large pins are heavy and bear a large load in the structure. The above-mentioned hydraulic gear rack moving mechanism can not only realize automatic adjustment, but also accurately adjust the left and right and height positions of the pins, so that the transmission parts can maintain a suitable meshing gap and transmission angle, reduce vibration, noise and energy loss during the transmission process, improve transmission efficiency and accuracy, and extend the service life of the equipment.

[0025] A push hydraulic cylinder 12 is installed at the bottom of the axle pin installation tray 10, and the telescopic end of the push hydraulic cylinder 12 is connected to a push frame 13, and the other end of the push frame 13 is against a large axle pin 16, and the large axle pin 16 is located above the axle pin installation tray 10. A U-shaped groove for placing the large axle pin 16 is opened at the center of the axle pin installation tray 10, and the large axle pin 16 and the U-shaped groove are in sliding contact. By starting the push hydraulic cylinder 12, the push frame 13 is driven to push the large axle pin 16 forward for installation.

[0026] A positioning electromagnet 14 and an optical aligner 15 are installed at one end of the shaft pin installation tray 10 away from the push hydraulic cylinder 12. The positioning electromagnet 14 and the optical aligner 15 can realize automatic calibration when installing the large shaft pin 16, so that it can achieve the best clearance or interference fit state with the matching parts, avoid poor fit caused by installation deviation, such as looseness, jamming and other problems, thereby ensuring the transmission accuracy and stability of the equipment.

[0027] The hydraulic unit 7 is generally composed of a hydraulic power source, a hydraulic actuator, a gear transmission device, and related control and auxiliary components.

[0028] Hydraulic power source: generally composed of a motor, a hydraulic pump, an oil tank, and a filter. The motor provides power to the hydraulic pump, which converts mechanical energy into hydraulic energy, draws oil from the oil tank and outputs high-pressure oil, providing a power source for the entire system. The filter is used to filter impurities in the oil to ensure the cleanliness of the oil, so as to prevent impurities from entering the system and causing component wear or blockage.

[0029] Hydraulic actuator: The most commonly used one is the hydraulic motor. The hydraulic motor is a device that converts hydraulic energy into mechanical energy. It relies on the pressure difference generated by the input high-pressure oil to drive its rotor to rotate, thereby outputting torque and speed. According to different application requirements, different types of hydraulic motors can be selected, such as gear motors, vane motors, plunger motors, etc.

[0030] Gear transmission device: It is composed of gears, transmission shafts, bearings and gear boxes. The output shaft of the hydraulic motor is connected to the driving gear in the gear transmission device. The driving gear meshes with other driven gears. Through the meshing transmission between the gears, the torque and speed of the hydraulic motor are transmitted to the components to be driven, realizing the rotation of the gears. The gear box is used to accommodate components such as gears and transmission shafts, and plays a role in support, protection and sealing. Different transmission ratios can be set as needed to meet different working requirements.

[0031] Control components: including various hydraulic valves, such as overflow valves, pressure reducing valves, reversing valves, throttle valves, etc. The overflow valve is used to limit the maximum pressure of the system to protect the system safety; the pressure reducing valve is used to reduce the system pressure to the required pressure value to provide a stable working pressure for specific components; the reversing valve is used to control the flow direction of the oil, thereby changing the rotation direction of the hydraulic motor; the throttle valve controls the speed of the hydraulic motor by adjusting the flow of the oil.

[0032] Auxiliary components: such as oil pipes, pipe joints, pressure gauges, accumulators, etc. Oil pipes and pipe joints are used to connect various hydraulic components to form a complete hydraulic circuit, so that the oil can flow smoothly in the system; the pressure gauge is used to monitor the pressure value in the system so that the operator can understand the working status of the system; the accumulator can store excess hydraulic energy and release it when needed, playing a role in stabilizing system pressure, replenishing oil and emergency energy, etc.

[0033] The hydraulic unit 7 uses oil as the working medium and relies on the pressure inside the oil to transmit power. Specifically, the high-pressure oil output by the hydraulic power source is transported to the hydraulic motor through an oil pipe. Inside the hydraulic motor, the oil drives the rotor of the motor to rotate, and the rotational motion of the rotor is transmitted to the driving gear of the gear transmission device through the output shaft. The driving gear and the driven gear are meshed with each other. According to the principle of gear transmission, the rotation of the driving gear drives the driven gear to rotate, thereby realizing the rotational motion of the gear, and finally driving the translation hydraulic gear 5 / lifting hydraulic gear 9 connected to the gear to complete the corresponding work task. In this process, the control element can accurately control the speed, torque and rotation direction of the hydraulic motor by adjusting the pressure, flow rate and flow direction of the oil according to actual work needs, thereby controlling the motion state of the gear. Among them, the hydraulic system can generate a large pressure, and when the gear is driven by the hydraulic motor, a very high torque can be output, which enables it to easily drive the rotation of the gear with a large load; in addition, the flow of the hydraulic oil is continuous and stable, which can provide a stable driving force for the gear, reduce vibration and impact, and ensure the stability of the gear rotation, which is suitable for the situation where the running stability is high in this application.

[0034] A plurality of running wheels 2 are symmetrically mounted on the bottom of the mechanism chassis 1 .

[0035] A plurality of support devices 3 are symmetrically installed at the bottom of the mechanism chassis 1. The support device 3 adopts a hydraulic telescopic support mechanism. The hydraulic telescopic support mechanism is a support device that uses a hydraulic system to achieve a telescopic function, and includes the following structures:

[0036] Hydraulic cylinder: It is the core component of the hydraulic telescopic support mechanism, which consists of a cylinder barrel, a piston, a piston rod, a seal, etc. The cylinder barrel is the outer shell of the hydraulic cylinder, which contains the piston and hydraulic oil; the piston divides the inside of the cylinder barrel into two chambers, namely the rod chamber and the rodless chamber. Under the pressure of the hydraulic oil, the piston reciprocates in the cylinder barrel, driving the piston rod to extend or retract.

[0037] Hydraulic pump station: provides power source for the entire mechanism, including motor, oil pump, oil tank, filter, relief valve, etc. The motor drives the oil pump to extract and pressurize the hydraulic oil in the oil tank, and then delivers it to the hydraulic cylinder and other actuators through the oil pipe; the filter is used to filter impurities in the hydraulic oil to ensure the cleanliness of the oil; the relief valve is used to adjust and limit the system pressure to prevent the system from overloading.

[0038] Control components: mainly include various valves, such as reversing valves, throttle valves, pressure reducing valves, etc. The reversing valve is used to control the flow direction of the hydraulic oil, so as to realize the reversal of the extension and contraction of the hydraulic cylinder; the throttle valve is used to adjust the flow of the hydraulic oil and control the extension and contraction speed of the hydraulic cylinder; the pressure reducing valve is used to adjust the pressure of a certain part of the system to meet different working requirements.

[0039] Auxiliary components: such as oil pipes, pipe joints, pressure gauges, etc. Oil pipes are used to connect various hydraulic components and transport hydraulic oil; pipe joints are used to ensure the connection and sealing between oil pipes and between oil pipes and hydraulic components; pressure gauges are used to display system pressure, which is convenient for operators to monitor and adjust the system working status.

[0040] The hydraulic telescopic support mechanism works based on the Pascal principle. When the oil pump of the hydraulic pump station is started, the hydraulic oil is sucked out of the oil tank and pressurized to form an oil with a certain pressure and flow rate. By operating the control element, such as the reversing valve, the pressure oil enters the rodless chamber of the hydraulic cylinder. At this time, the pressure in the rodless chamber increases, pushing the piston to drive the piston rod to extend, realizing the extension action of the support mechanism and supporting the object. When retraction is required, the reversing valve is used to change the flow direction of the oil so that the pressure oil enters the rod chamber. At the same time, the oil in the rodless chamber flows back to the oil tank. Under the action of pressure, the piston drives the piston rod to retract, completing the retraction action of the support mechanism. By adjusting the opening of the throttle valve, the oil flow entering the hydraulic cylinder can be controlled, thereby adjusting the telescopic speed of the piston rod to meet different work requirements. The hydraulic telescopic method has the advantages of large output force, fast telescopic speed, and smooth action. It is suitable for large-scale mechanical equipment in this application that requires large load support and rapid telescopic occasions.

[0041] In addition, in this embodiment, when the mechanism chassis 1 moves to a suitable position under the action of the running wheels 2, the support device 3 can quickly extend its support to play a braking role, while also playing a certain supporting role, thereby avoiding the problem that the mechanism chassis 1 will move under the action of the running wheels 2, thereby affecting the precise installation effect.

[0042] The lifting bracket 8 includes vertical rods symmetrically distributed in the front-to-back direction and the left-to-right direction, and the top and bottom of the vertical rods are fixedly connected together by a cross beam.

[0043] The action process of the present invention is as follows:

[0044] First, the mechanism chassis 1 is moved to the axle pin storage area under the action of the walking wheel 2; then, the axle pin is grabbed by the mechanical arm and grabbing fixture of the axle pin grabbing and lifting system, and lifted to the axle pin installation tray 10; after that, according to the installation position, the translation hydraulic gear 5 is moved on the translation rack 4 to adjust the position of the translation base 6, and the lifting hydraulic gear 9 is moved on the lifting rack 11 to adjust the position of the axle pin installation tray 10 on the lifting bracket 8, and the optical alignment instrument 15 and the positioning electromagnet 14 are used to adjust the posture of the large axle pin 16 to align it with the installation hole; finally, the push hydraulic cylinder 12 is started to push the large pin shaft 16 forward to carry out the installation operation.

[0045] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
