The working process of the utility model is as follows: at first remove the position that needs the construction with this construction support, then start actuating mechanism, make threaded sleeve 51 rotate, because the limiting action of propping up supporting bench 4 and two sets of helicitic texture, threaded rod 52 can only go up and down in vertical direction to realize the function of propping up supporting bench 4 height-adjustable, according to the construction environment at last, adjust supporting bench 4 to suitable height and can close actuating mechanism, under the auto-lock condition of threaded sleeve 51 and threaded rod 52, supporting bench 4 can not descend, can guarantee the stability of supporting. Of course, in order to make the support more stable, the structure of the auxiliary guide cylinder and the guide rod can be added properly.

To actuating mechanism, the concrete scheme that this application provided is, actuating mechanism includes biax servo motor 54, transmission shaft 55, driving gear 56 and driven gear 57, be equipped with two supporting seats 53 in the mounting box 2, biax servo motor 54 is located between two supporting seats 53, and transmission shaft 55 includes two, and its middle part rotates with two supporting seats 53 respectively and is connected, and one end links to each other with two output shafts of biax servo motor 54 respectively, and the other end is equipped with driving gear 56, driven gear 57 is installed on threaded sleeve 51 and is engaged with driving gear 56 mutually. The working process is as follows: when the double-shaft servo motor 54 rotates, the transmission shaft 55 can be driven to rotate, and the transmission shaft 55 drives the threaded sleeve 51 to rotate through the driving gear 56. Since the threaded sleeve 51 has a certain length, in order to ensure the stability of the rotation of the threaded sleeve 51, bearings may be provided at the bottom and upper portions thereof passing through the mounting box 2, so that the upper and lower portions are received stably. In addition, because the double-shaft servo motor 54 causes the rotation directions of the threaded sleeves 51 at the two ends to be opposite, the thread turning directions of the two sets of threaded sleeves 51 and the threaded rods 52 are opposite, and synchronous lifting of the two threaded rods 52 is guaranteed.

Further, in order to move the construction support conveniently, a moving mechanism 6 is arranged at the bottom of the base 1, the moving mechanism 6 comprises a fixed box 3 and a lifting mechanism 7 located in the fixed box 3, and rollers 63 are arranged at the bottom of the lifting mechanism 7.

The lifting mechanism 7 is used for lifting the roller 63, and when the construction support is normally used, the roller 63 needs to be retracted, so that the base 1 is in contact with the ground, and the stability of support is ensured; when the construction support needs to be moved, the roller 63 is put down by using the lifting mechanism, the base 1 is jacked up, only the roller 63 contacts with the ground, and the construction support can be easily moved.

For the specific structure of the landing gear, a simple hydraulic rod, pneumatic rod, linear motor or the like can be adopted. The application provides another kind of structural style, as shown in fig. 2, promptly the rising and falling mechanism includes driving motor 71, fixed plate 61 and fly leaf 62, driving motor 71 is installed at fixed box 3 top, and its output shaft 72 is down to be equipped with wedge carousel 76 on output shaft 72, be equipped with the ring channel on the wedge face of wedge carousel 76, fixed plate 61 and fixed box 3 middle part fixed connection are equipped with the through-hole on the fixed plate 61, fly leaf 62 is located fixed plate 61 below, is equipped with bracing piece 64 on the fly leaf 62, has cup jointed spring 65 on the bracing piece 64, bracing piece 64 passes behind the through-hole with the ring channel joint on the wedge carousel 76 and can follow the ring channel and slide. The working process is as follows: when the roller 63 needs to be put down, the driving motor 71 drives the wedge-shaped turntable 76 to rotate, the annular chute on the wedge-shaped turntable 76 drives the supporting rod 64 to move downwards, so that the movable plate 62 and the roller 63 descend, until the lowest point of the wedge-shaped turntable 76 is aligned with the supporting rod 64, the movable plate 62 reaches the lowest point, and the roller 63 just meets the use requirement at this time; when the roller 63 needs to be retracted, the wedge-shaped rotating disc 76 is continuously rotated, the annular groove drives the supporting rod 64 to move upwards, until the highest of the annular groove is aligned with the supporting rod 64, the movable plate 62 reaches the highest, and the roller 63 is separated from the ground. The spring 65 plays a role in resetting in the rising and falling processes of the roller 63 and plays a role in buffering in the moving process of the construction support

Further, in order to ensure the rising and falling stability of the moving mechanism, the top of the fixed box 3 is further rotatably provided with a rotating rod 73, the output shaft 72 of the driving motor 71 and the rotating rod 73 are both provided with a belt pulley 74, the belt pulley 74 is connected with a belt 75 in a winding manner, the rotating rod 73 is also provided with a wedge-shaped turntable 76, the wedge-shaped turntable 76 is symmetrically arranged with the wedge-shaped turntable 76 on the output shaft 72 of the driving motor 71, and the movable plate is provided with two support rods 64 which are respectively connected with the two wedge-shaped turntables 76 in a sliding manner.
