Embodiment

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0021] A split-type bottom-lifting device for hydraulic support moving, including a base 1, two columns 2 are symmetrically installed at the top end of the base 1, a top beam 3 is installed at the top of the two columns 2, bidirectional lead screws 6 are provided on both sides of the base 1, two threaded sleeves 7 are symmetrically and threadedly connected to both sides of the outer walls of the two bidirectional lead screws 6, one end of each group of threaded sleeves 7 that is not adjacent to the outer wall is fixedly installed with an extension frame 9, the top ends of the four extension frames 9 are all threadedly connected with adjusting bolts 10, the bottom ends of the four adjusting bolts 10 are all rotatably installed with support pads 11 through the provided rotating shafts, a reinforcing bottom plate 4 is fixedly installed at the bottom end of the base 1, the provided adjusting bolts 10 are located at the four sides of the device, and balanced support force can be provided through four-side support, reducing the inclination and shaking of the base 1, improving the overall stability, and the settable position can adapt to different ground conditions to ensure that the device can maintain stability in various environments. The top ends of the four adjusting bolts 10 are all fixedly installed with fastening bolts 12, and the sizes of the four fastening bolts 12 are all the same. The setting of the fastening bolts 12 serves to assist in rotating the adjusting bolts 10.

[0022] In this embodiment, the adjacent sides of the outer walls of the two groups of threaded sleeves 7 are all slidably connected to the adjacent outer walls of the base 1, the sizes of the four threaded sleeves 7 are all the same, one end of each of the two bidirectional lead screws 6 penetrates through one of the mounting seats 5 and is fixedly installed with a polygonal block 13. The setting of the polygonal block 13 serves to assist in rotating the bidirectional lead screw 6.

[0023] In this embodiment, snap rings 14 are snap-fitted on the outer walls of the two polygonal blocks 13, limit rods 15 are fixedly installed on the outer walls of the two snap rings 14, extension blocks 16 are fixedly installed at the top ends of two of the mounting seats 5, slots are opened at one ends of the two extension blocks 16 that are not adjacent, and a part of the outer walls of the two limit rods 15 are snap-fitted with the inner walls of the adjacent slots. The sizes of the two polygonal blocks 13 are all the same, and the sizes of the two snap rings 14 are all the same. By inserting the snap ring 14 on the outer wall of the polygonal block 13 and pressing the limit rod 15 to rotate, the polygonal block 13 can be driven to rotate, thereby realizing the rotation of the bidirectional lead screw 6, and inserting the limit rod 15 into the slot opened on the extension block 16 plays a limiting role on the polygonal block 13, and can maintain the stability of the bidirectional lead screw 6 when no adjustment is required, and further maintain the stability of the position of the adjusting bolt 10.

[0024] In this embodiment, moving wheels 8 are installed at the bottom ends of the outer walls of the four threaded sleeves 7, the height of the moving wheels 8 corresponds to the position of the reinforcing bottom plate 4, and the setting of the moving wheels 8 can play an auxiliary moving role when adjusting the movement of the threaded sleeve 7.

[0025] Working principle: When in use, the device is supported by the base 1. The provided reinforcement base plate 4 plays a role in strengthening the bottom support. When additional support for the base 1 is further required, the snap ring 14 is snapped onto the polygon block 13, and the polygon block 13 is rotated by rotating the limit rod 15, further driving the rotation of the bidirectional lead screw 6. The bidirectional lead screw 6 converts the rotary motion into a linear motion. Therefore, it can drive two adjacent threaded sleeves 7 to move in opposite directions, further driving two adjacent extension frames 9 to move away from each other. After moving to a suitable position, manually rotate the fastening bolt 12 to drive the adjusting bolt 10 to spiral downwards. With the cooperation of the rotating shaft, it drives the support backing plate 11 to extrude the support surface, thereby increasing the support range of the base 1, dispersing its support strength, and playing an auxiliary support role. After the adjustment is completed, the limit rod 15 can also be aligned with the card slot opened on the extension block 16, and the snap ring 14 is inserted into the polygon block 13, enabling the limit rod 15 to be limited by the card slot, realizing the limitation of the polygon block 13.
