[0026] EMBODIMENT

[0027] REFERENCE Figs. 1-4 For the embodiment of the utility model, the embodiment provides an online electric opening machine for pressure pipeline, which comprises,

[0028] The hole-opening mechanism 100 includes a valve body 101, a hole-opening tool 102 for hole-opening operations, and a support assembly 103 for supporting the hole-opening tool 102.

[0029] The adaptive adjustment mechanism 200 includes a horizontal plate 201, a limiting component 202 disposed on the top of the horizontal plate 201, a first arm 203 hinged to one side of the bottom of the horizontal plate 201 for adjusting the height, a second arm 204 cross-hinged with the first arm 203, a support roller 205 rotatably mounted on the second arm 204 for guiding, and a bearing 206 hinged to the end of the second arm 204.

[0030] The drilling mechanism 100, through the coordinated action of the valve body 101 and the drilling cutter 102, can efficiently complete the drilling operation of pressurized pipelines. The design of the bearing component 103 provides stable support for the drilling cutter 102, ensuring accuracy and stability during the drilling process. The adaptive adjustment mechanism 200, through the coordinated action of the horizontal plate 201, the limiting component 202, the first arm 203, the second arm 204 and the support roller 205, can effectively adapt to different terrain environments and ensure stable contact between the bottom of the equipment and the ground.

[0031] Specifically, the adaptive adjustment mechanism 200 also includes a servo motor 207 for driving the rotation of the second arm 204, a drive shaft 208 fixedly mounted on both output ends of the servo motor 207, and a support base plate 209 fixedly mounted on the bottom of the bearing 206.

[0032] The end of the drive shaft 208 is fixedly connected to the outside of the second arm 204, and the bottom of the servo motor 207 is fixedly connected to the top of the support base plate 209.

[0033] The cross-hinged design of the first boom 203 and the second boom 204 allows the equipment to automatically adjust the position of the support base plate 209 according to the terrain height, thereby maintaining the equipment's levelness on slopes or soft soil. The rotating installation of the support rollers 205 further enhances the equipment's guidance and flexibility, enabling it to move smoothly in complex terrain. The coordinated use of the servo motor 207 and the drive shaft 208 provides precise driving capability for the second boom 204, ensuring the stability and accuracy of the equipment when adjusting its height. The fixed installation of the support base plate 209 provides a solid support foundation for the equipment, further improving its stability and safety.

[0034] Further, the limiting assembly 202 comprises a limiting groove seat 202a fixedly installed at the top of the horizontal plate 201, a limiting shell 202b movably sleeved on the limiting groove seat 202a and fixedly connected with the bottom of the bearing assembly 103 at the outer side, a plug rod 202c fixedly installed at the opening of the inner cavity of the limiting groove seat 202a, and a magnetic block 202d fixedly installed at the end of the plug rod 202c. The limiting assembly 202 further comprises a groove 202e opened in the inner cavity of the limiting shell 202b, a magnet block 202f fixedly installed in the inner cavity of the groove 202e, a buffer spring 202g fixedly installed at the outer side of the magnet block 202f, and a guide ring 202h fixedly installed at the end of the buffer spring 202g.

[0035] The bearing assembly 103 can move freely within the limiting range through the limiting assembly 202, and the device is prevented from tilting or deviating due to excessive movement. Meanwhile, the limiting assembly 202 is arranged below the opening mechanism 100 to realize self-adaptive adjustment, and the plug rod 202c and the magnetic block 202d further enhance the stability of the limiting assembly 202 after installation, ensuring that the bearing assembly 103 always maintains a vertical state during operation.

[0036] The magnet block 202f, the buffer spring 202g and the guide ring 202h provide buffering and guiding functions for the limiting assembly 202, and can be quickly disassembled, reducing the impact of the device due to uneven ground or vibration during operation, and further improving the stability and safety of the device.

[0037] Preferably, the bearing assembly 103 comprises a support ring plate 103a fixedly installed at the outer side of the valve body 101, a support rod 103b fixedly installed at the outer side of the support ring plate 103a, and a support frame 103c movably sleeved on the outer side of the support rod 103b. The bearing assembly 103 further comprises a limiting block 103d fixedly installed at the end of the support rod 103b for limiting the movement range of the support frame 103c, and a limiting rod 103e fixedly installed at the outer side of the support ring plate 103a and movably sleeved in the inner cavity of the support frame 103c.

[0038] The fixed installation of the support ring plate 103a and the support rod 103b ensures the overall rigidity of the bearing assembly 103, enabling it to remain stable in complex terrain. The movable sleeving design of the support frame 103c provides a certain movement space for the opening cutter 102, enabling it to be finely adjusted according to the operation requirements. The addition of the limiting block 103d and the limiting rod 103e further limits the movement range of the support frame 103c, preventing the device from shaking or deviating during operation.

[0039] Further, the opening mechanism 100 further comprises a driving motor 104 for driving the opening cutter 102, and a flange 105 fixedly installed outside the valve body 101 for connecting the pipeline.

[0040] The driving motor 104 provides strong power for the opening cutter 102, ensuring the efficiency of the opening operation, and the design of the flange 105 facilitates the quick connection of the equipment and the pipeline.

[0041] In use, first, the adaptive adjustment mechanism 200 automatically adjusts the position of the support bottom plate 209 according to the terrain height through the cooperation of the first arm rod 203, the second arm rod 204 and the support roller 205, so that the equipment remains horizontal under the condition of slope or soft soil;

[0042] Subsequently, the opening mechanism 100 performs the opening operation through the cooperation of the valve body 101 and the opening cutter 102 under the driving of the driving motor 104, the bearing assembly 103 provides support for the opening cutter 102, and the limiting assembly 202 ensures that the bearing assembly 103 moves within the limiting range;

[0043] The servo motor 207 and the driving shaft 208 drive the second arm rod 204 to adjust the height of the equipment, ensuring the stability during the operation process, and the flange 105 is used for the quick connection of the equipment and the pipeline, and after the opening operation is completed, the equipment can be disassembled or moved as needed.

[0044] In summary, through the cooperative design of the opening mechanism 100 and the adaptive adjustment mechanism 200, the instability problem of the equipment during operation in different terrain environments is effectively solved, the adaptive adjustment mechanism 200 can automatically adjust the position of the equipment according to the terrain height, ensuring that the equipment remains horizontal under the condition of slope or soft soil, improving the adaptability and stability of the equipment, and the opening mechanism 100 provides stable support and precise limiting function for the opening cutter 102 through the cooperation of the bearing assembly 103 and the limiting assembly 202, ensuring the precision and safety during the opening process.
