[0026] In this embodiment, preferably, the top of the support plate 4 is fixedly connected with a gantry 11, the top, front side and rear side of the gantry 11 are threadedly connected with a clamping screw 12, the ends of the clamping screws 12 on the front and rear sides are rotatably provided with side pressure plates 13, and the bottom end of the top clamping screw 12 is fixedly connected with an upper pressure plate 14;
[0027] Specifically, the steel structure to be connected is placed on the support plate 4, the clamping screws 12 on the front and rear sides are rotated to move and clamp the steel structure through the side pressure plate 13, and then the upper clamping screw 12 is rotated to drive the upper pressure plate 14 to move downward to clamp the steel structure. Whether the steel structure is a round steel pipe or a square steel, it can be locked.
[0028] In this embodiment, preferably, the front end of the longitudinal screw rod 7 passes through and extends to the front side of the support bracket 2, and the front end of the longitudinal screw rod 7 is provided with a front hexagonal groove 15;
[0029] Specifically, a wrench can be inserted into the front hexagonal slot 15 to facilitate the control of the rotation of the longitudinal screw rod 7 .
[0030] In this embodiment, preferably, the inner side of the support bracket 2 is fixedly connected with longitudinal sliding shafts 16 that are symmetrically distributed on the left and right, and the two sides of the horizontal frame 3 are fixedly connected with evenly distributed ear plates 17, and a plurality of ear plates 17 can be slidably arranged on the two longitudinal sliding shafts 16 correspondingly;
[0031] Specifically, when the longitudinal screw 7 drives the horizontal frame 3 to move through the nut 8, the horizontal frame 3 will have a tendency to rotate circumferentially. At this time, the ear plate 17 on the side of the horizontal frame 3 moves along the longitudinal sliding shaft 16 to limit the horizontal frame 3, so that the horizontal frame 3 can move in a straight line.
[0032] In this embodiment, preferably, the inner top wall of the horizontal frame 3 is rotatably connected with a vertical shaft 18, and two connecting gears 19 meshing with each other are fixedly sleeved on the outer wall of the vertical shaft 18 and the inner threaded sleeve 9 respectively;
[0033] Specifically, the vertical rotating shaft 18 and the connecting gear 19 connected thereto are rotated, and the rotating connecting gear 19 can drive another connecting gear 19 to drive the internal threaded sleeve 9 to rotate.
[0034] In this embodiment, preferably, the bottom end of the vertical shaft 18 passes through and extends to the bottom of the horizontal frame 3, and a lower hexagonal groove 20 is formed at the bottom end of the vertical shaft 18;

The vertical screw 10 will have a tendency to rotate circumferentially. At this time, the vertical sliding shaft 21 under the support plate 4 moves along the horizontal frame 3 to limit the position, so that the vertical screw 10 drives the support plate 4 to move vertically up and down.

[0039] Specifically, the motor 25 can drive the worm 26 to rotate, and then drive the worm wheel 27 to drive the longitudinal shaft 23 to rotate. When the longitudinal shaft 23 rotates, it drives the travel gear 24 to rotate and cooperate with the toothed plate 28 to move the support bracket 2 for docking.
[0040] The working principle and use process of this utility model:
[0041] First, place the steel structure to be docked on the support plate 4, rotate the front and rear compression screws 12 to move and clamp the steel structure through the side pressure plate 13, and then rotate the upper compression screw 12 to drive the upper pressure plate 14 to move downward to press the steel structure. Whether the steel structure is a round steel pipe or a square steel, it can be locked, and the application range is wide. After being fixed, the steel structure is parallel to the base frame 1, which is convenient for subsequent docking;
[0042] Secondly, after the steel structure is fixed, the motor 25 can drive the worm 26 to rotate, and then drive the worm wheel 27 to drive the longitudinal shaft 23 to rotate. When the longitudinal shaft 23 rotates, it drives the travel gear 24 to rotate and cooperate with the tooth plate 28, so that the support bracket 2 moves and drives the steel structure on the support plate 4 to dock. It should be noted that at this time, there is a slight contact or a small gap between the two steel structures to be docked.
[0043] Next, according to the position of the steel structure after clamping, the longitudinal screw 7 is driven to rotate by inserting a wrench into the front hexagonal slot 15, and the longitudinal screw 7 drives the horizontal frame 3 to move along the axial direction of the longitudinal screw 7 through the nut 8, thereby realizing the adjustment of the front and rear position of the steel structure; the wrench is inserted into the lower hexagonal slot 20 to drive the vertical shaft 18 to rotate, and the connecting gear 19 sleeved on the vertical shaft 18 rotates accordingly, and the internal threaded sleeve 9 is rotated through another connecting gear 19 meshing with it, and the internal threaded sleeve 9 drives the vertical screw 10 to move vertically to push the support plate 4, thereby realizing the adjustment of the height position of the steel structure;
[0044] Finally, after the horizontal and height positions of the two steel structures to be butted are adjusted to be consistent, the motor 25 is turned on again to make the two steel structures to be butted completely contact with each other to achieve butt connection, so as to facilitate subsequent processes.
[0045] In summary, after the steel structure is fixed, the utility model can move the steel structure in the horizontal direction, front-to-back direction, and up-and-down direction, so as to achieve comprehensive adjustment during the docking process, without the need for repeated disassembly and assembly to achieve adjustment, thus saving time and effort, improving docking efficiency, and ensuring docking accuracy.
[0046] The electronic components and modules used in the content of this utility model can all be parts that are commonly used in the market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
