[0028] Further, as Figure 1 And Figure 3As shown, the support frame 2 is internally fixed with a servo motor 21; the output end of the servo motor 21 is installed with a first gear 22; the inside of the support table 1 is rotationally connected with a second threaded rod 23; one end of the second threaded rod 23 is fixedly connected with a second gear 26; the second gear 26 is engaged with the support frame 2; the outer side wall of the second threaded rod 23 is threadedly connected with a connecting plate 24; the connecting plate 24 is in sliding contact with the support frame 11; the outer side wall of the connecting plate 24 is fixedly connected with two pairs of universal wheels 25. At the end of the construction of the last paragraph, the entire device needs to be moved to the next construction area, at which time the workers hold the support table 1 and start the servo motor 21. The servo motor 21 will drive the first gear 22 to rotate, and through the cooperation between the first gear 22 and the second gear 26, the second gear 26 will rotate, thereby causing the second threaded rod 23 to rotate, and through the threaded cooperation between the second threaded rod 23 and the connecting plate 24, the support frame 11 limits the connecting plate 24, at which time the connecting plate 24 will move downward, causing the universal wheels 25 to contact the ground. Under the condition that the workers hold the support table 1, the servo motor 21 continues to work until the support frame 11 is separated from the ground, and then the servo motor 21 is stopped. At this time, the sliding friction between the device and the ground becomes rolling friction. Through the setting of the connecting plate 24 and the universal wheels 25, when the workers encounter long-distance equipment transfer, the difficulty of the workers transferring the equipment is reduced, and the workers use the equipment conveniently.

[0029] Further, as shown in Figure 4 The side wall of the sliding block 13 is fixedly connected with a pair of angle plates 3; the side wall of the limiting frame 12 is provided with a plurality of threaded positioning holes 31; the angle plate 3 is connected with the threaded positioning hole 31 through a fixing bolt 32; the fixing bolt 32 can be separated from the angle plate 3. During equipment operation, the sliding block 13 plays an important role. After the equipment is adjusted, the fixing bolt 32 is connected with the threaded positioning hole 31, at which time the fixing bolt 32 connects the angle plate 3 with the limiting frame 12. Through the setting of the angle plate 3 and the fixing bolt 32, the sliding block 13 can be additionally fixed and limited, thereby increasing the stability of the equipment during operation.

When the equipment is working, the second gear 26 will rotate. Because the environment where the equipment is located is a construction site with a lot of dust, the bristles 41 will rub against the second gear 26 when the second gear 26 rotates. At this time, the bristles 41 will clean the dust and impurities attached to the side wall of the second gear 26. Through the brush plate 4 and the bristles 41, the probability of jamming failure between the first gear 22 and the second gear 26 caused by dust and impurities is reduced.

[0031] Furthermore, such as Figure 3 As shown, one end of the second threaded rod 23 is fixedly connected to a limiting plate 5; the limiting plate 5 is located below the connecting plate 24. When the equipment is working, the limiting plate 5 can limit the maximum position of movement of the connecting plate 24. By setting the limiting plate 5, the range of movement of the connecting plate 24 is controlled, reducing the possibility of the connecting plate 24 detaching from the equipment.

[0032] Furthermore, such as Figure 1 As shown, a storage box 6 is fixedly attached to the top of the outer wall of the support platform 1; the storage box 6 does not contact the cross connecting block 17. When the equipment is in operation, the operator can place the turntable 18 inside the storage box 6 to store it. The storage box 6 facilitates the operator's storage of the turntable 18, reducing the probability of it being lost.

[0033] Furthermore, such as Figure 1 As shown, a baffle 7 is fixedly connected to the side wall of the support frame 2; the baffle 7 is positioned above the second gear 26; the baffle 7 is made of plastic. During operation, the baffle 7 can intercept falling debris and other objects, reducing the probability of these objects contacting the second gear 26, thus increasing protection for the second gear 26 and reducing the likelihood of the equipment malfunctioning due to damage to the second gear 26.

[0034] Working principle: when the device works, insert the cross connecting block 17 into the first threaded rod 16, at this time rotate the rotating disc 18 to make the first threaded rod 16 follow the rotation, through the thread cooperation between the first threaded rod 16 and the sliding block 13, and the limitation of the limiting frame 12 to the sliding block 13, at this time the sliding block 13 will slide, and then the position of the hydraulic jack body 14 changes, after adjustment, the cross connecting block 17 is separated from the first threaded rod 16, at this time the first threaded rod 16 is difficult to be rotated, and the sliding block 13 no longer slides, then start the hydraulic jack body 14 to support the position needed, through the first threaded rod 16 and the sliding block 13, the staff can change the position of the device support within a certain range quickly according to the actual situation, reduce the situation of carrying the device to change the support position, reduce the time spent by the staff to change the support position, at the end of the last paragraph construction, the whole device needs to be moved to the next construction area, at this time the staff holds the support table 1 and starts the servo motor 21.The servo motor 21 drives the first gear 22 to rotate, and through the cooperation between the first gear 22 and the second gear 26, the second gear 26 rotates, and then the second threaded rod 23 rotates, and through the threaded cooperation between the second threaded rod 23 and the connecting plate 24, the supporting frame 11 limits the connecting plate 24, at this time, the connecting plate 24 moves downward, and the universal wheel 25 contacts the ground, and the staff holds the support table 1, the servo motor 21 continues to work until the supporting frame 11 is separated from the ground, and then the servo motor 21 is stopped, at this time, the sliding friction between the equipment and the ground becomes rolling friction, through the connecting plate 24 and the universal wheel 25, when the staff meets the long-distance moving equipment, the difficulty of the staff moving the equipment is reduced, and the staff is convenient for using the equipment, when the equipment works, the sliding block 13 plays an important role, when the equipment is adjusted, the fixed bolt 32 is connected with the threaded positioning hole 31, at this time, the fixed bolt 32 connects the angle plate 3 and the limiting frame 12 together, through the angle plate 3 and the fixed bolt 32, the sliding block 13 can be additionally fixed and limited, and then the stability of the equipment during work is increased, when the equipment works, the second gear 26 rotates, because the environment of the equipment is a construction site, dust is large, when the second gear 26 rotates, the bristles 41 rub against the second gear 26, at this time, the bristles 41 clean the dust and impurities attached to the side wall of the second gear 26, through the brush plate 4 and the bristles 41, the probability that the cooperation between the first gear 22 and the second gear 26 is blocked due to dust and impurities is reduced, when the equipment works, the limiting disc 5 can limit the maximum position of the connecting plate 24, through the limiting disc 5, the movement range of the connecting plate 24 is controlled, and the situation that the connecting plate 24 is separated from the equipment is reduced, when the equipment works, the staff removes the rotating disc 18, the rotating disc 18 can be placed in the storage box 6, the storage box 6 can store the rotating disc 18, through the storage box 6, the staff is convenient for storing the rotating disc 18, and the probability that the rotating disc 18 is lost is reduced, when the equipment works, the baffle 7 can intercept the falling debris and other articles above, through the baffle 7, the probability that the articles falling above contact the second gear 26 is reduced, the protection of the second gear 26 is increased, and the situation that the equipment cannot be normally used due to damage of the second gear 26 is reduced.
