[0002] Speed ​​reduction equipment, usually referring to a speed reducer or reducer, is a mechanical device that converts high-speed input motion into low-speed output. It increases the output torque by reducing the rotational speed to meet the power requirements of different mechanical equipment during operation; the assembly of forgings for speed reduction equipment refers to the process of combining pre-forged metal forgings with the speed reduction equipment for assembly and assembly during the manufacturing process of the speed reduction equipment; the hydraulic jacking of forgings for speed reduction equipment refers to a technology that uses a hydraulic jacking device to accurately install and assemble the forgings in the speed reduction equipment.

[0024] See also Figures 1 to 6 In an embodiment of the present utility model, a hydraulic jacking device for assembling forgings of a reduction gear includes a hydraulic jack 1, a displacement mechanism 3 is provided below the hydraulic jack 1, a transposition mechanism 2 is provided below the displacement mechanism 3, and the transposition mechanism 2 includes a support bracket 201, a support column 202, a hydraulic rod 203, a turntable body 204, a support tray 205 and a roller body 206. The lower end of the support bracket 201 is fixedly mounted with the support column 202, the middle part of the support bracket 201 is fixedly mounted with the hydraulic rod 203, the transmission end of the hydraulic rod 203 is mounted with the turntable body 204, the lower end of the turntable body 204 is fixedly mounted with the support tray 205, and the lower end of the support tray 205 is mounted with the roller body 206. Four groups of support columns 202 are fixedly mounted on the bottom end of the support bracket 201, and four groups of roller bodies 206 are mounted on the bottom end of the support tray 205.

[0025] The support bracket 201 provides a stable support base to ensure the stability of the entire hydraulic jacking device during operation. The support column 202 serves as a load-bearing structure to increase the load-bearing capacity of the device, ensure the structural robustness when lifting heavy objects, and avoid structural deformation caused by excessive weight. The hydraulic rod 203 provides additional power to enable components such as the turntable body 204 to be lifted, allowing the hydraulic jack 1 to rotate, thereby increasing the adaptability of the device and meeting assembly requirements at different angles and positions. When the hydraulic jack 1 needs to be moved, the roller body 206 provides a smooth movement effect.

[0026] The displacement mechanism 3 includes a mounting plate 301, a limit block 302, a limit screw 303, a limit slider 304, a supporting plate 305, a first adjusting screw 306, a first transmission gear 307, a first drive motor 308, a threaded sleeve 309, a second adjusting screw 310, a second transmission gear 311 and a second drive motor 312. A mounting plate 301 is provided below the hydraulic push rod 1. The limit block 302 is fixedly installed on the upper end of the mounting plate 301. The limit screw 303 is threadedly connected to the limit block 302. Multiple groups of limit blocks 302 and limit screws 303 are evenly distributed on the upper end of the mounting plate 301 from front to back. The limit slider 304 is fixedly installed on the lower end of the mounting plate 301. A supporting plate 305 is provided below the limiting slider 304, and the supporting plate 305 is slidably connected to the limiting slider 304. A first adjusting screw 306 is installed in the middle of the supporting plate 305, and the first adjusting screw 306 is threadedly connected to the mounting plate 301. A first transmission gear 307 is fixedly installed on the left end of the first adjusting screw 306, and a first driving motor 308 is provided on the left side of the first transmission gear 307. A threaded sleeve 309 is fixedly installed on the lower end of the supporting plate 305, and a second adjusting screw 310 is threadedly connected to the inner side of the threaded sleeve 309. A second transmission gear 311 is fixedly installed on the rear end of the second adjusting screw 310, and a second driving motor 312 is provided behind the second transmission gear 311.

[0027] The mounting plate 301 serves as the basis of the displacement mechanism 3. The mounting plate 301 provides a fixed platform to ensure the stability of the entire displacement mechanism 3. The limit block 302 limits the displacement range of the hydraulic push rod 1 to prevent excessive movement from causing damage to the equipment or loss of control, thereby ensuring the safety of operation. The displacement of the hydraulic push rod 1 can be accurately controlled by adjusting the limit screw 303. The limit slider 304 ensures that the hydraulic push rod 1 can move along the predetermined track during the displacement process. The support plate 305 provides a supporting plane so that the hydraulic push rod 1 remains stable during the horizontal displacement process. The user fine-tunes the hydraulic push rod 1 by rotating the first adjusting screw 306. The horizontal position of the rod 1 improves the assembly accuracy. The first transmission gear 307 converts the rotational power of the motor into linear motion of the first adjusting screw 306 to achieve precise displacement. The first drive motor 308 provides a power source for the displacement mechanism 3. The threaded sleeve 309 is used in conjunction with the second adjusting screw 310. The threaded sleeve 309 converts the rotational motion into the front and rear displacement of the hydraulic push rod 1 to achieve precise control. The second adjusting screw 310 is used to fine-tune the front and rear displacement of the hydraulic push rod 1 to enhance the flexibility of assembly. The second drive motor 312 provides power for the front and rear displacement, so that the hydraulic push rod 1 can be accurately adjusted front and rear to meet different assembly requirements.

[0028] The working principle of the present utility model is as follows: the hydraulic jacking device assembled with the supporting forging of the present deceleration equipment is additionally provided with a transposition mechanism 2 and a displacement mechanism 3. Before using the hydraulic jacking device assembled with the supporting forging of the present deceleration equipment, it is necessary to pre-connect the hydraulic jack 1, the hydraulic rod 203, the first drive motor 308 and the second drive motor 312 to electricity and connect to the control terminal. When using the hydraulic jacking device assembled with the supporting forging of the present deceleration equipment, if it is necessary to adjust the left and right positions of the hydraulic jack 1, the first drive motor 308 is activated to drive the first transmission gear 307 to rotate, thereby causing the first adjusting screw 306 to drive the mounting plate 301 and the hydraulic jack 1 to displace; if it is necessary to adjust the front and rear positions of the hydraulic jack 1, the second drive motor 312 is activated to drive the second transmission gear 311 to rotate, thereby causing the second transmission gear 311 to drive the upper threaded sleeve 309 and the parts above the threaded sleeve 309 to displace. In addition, if it is necessary to rotate the hydraulic jack 1, The position of the hydraulic push rod 1 is adjusted again, and the hydraulic rod 203 is activated to push the turntable body 204, the support tray 205 and the roller body 206 downward to lift all the parts above. At this time, the parts above the turntable body 204 can be rotated to realize the position rotation operation of the hydraulic push rod 1. In this state, all the parts above the support tray 205 and the roller body 206 can also be pushed to move; in summary, the displacement mechanism 3 adopts a dual-motor transmission structure, which can drive the hydraulic push rod 1 to perform precise displacement operations horizontally in the four directions of forward, backward, left and right, so that the hydraulic push rod 1 can be accurately moved to the bottom of the forging, thereby ensuring the stability and reliability of the forging assembly, and the transposition mechanism 2 adopts a dual structure of rotation and displacement, which can drive the upper hydraulic push rod 1 and the displacement mechanism 3 to rotate and adjust as a whole, and can also drive the hydraulic push rod 1 and the displacement mechanism 3 to perform position exchange operations as a whole, which is convenient for users to adjust and use.
