[0044] Embodiment 4

[0045] Based on embodiment 3, the present embodiment discloses that as Figure 1 , 2As shown in Figure 6, the mounting seat 12 is a cubic structure, and a circular hole penetrating the upper and lower end surfaces is provided in the central axis of the cubic structure. The cubic structure is an integral structure or is formed by connecting two cubes with semicircular holes at the inner ends through a bolt and nut assembly (refer to the structure of the positioning ring). The upper and lower ends of the front and rear surfaces of the mounting seat 12 are respectively provided with fixed plates 13, and a limit block 14 is relatively provided between the two fixed plates 13 on the same side. A vertically arranged linear slide is formed between the two limit blocks 14, and an adjustable bracket 17 is slidably connected in the linear slide. A vertically arranged lead screw 15 is provided in the linear slide. The two ends of the lead screw 15 are rotatably connected to the two fixed plates 13 respectively, the bottom end of the lead screw 15 passes through the fixed plate 13 on the lower side and is fixedly connected to the output shaft of the drive motor 20 preset on the outer wall of the fixed plate, the inner end of the adjustable bracket 17 slides with the inner wall of the linear slide, the lead screw 15 passes through the inner end of the adjustable bracket 17 and is screwed with the adjustable bracket 17, and a plurality of guide rods 16 are also vertically provided in the linear slide, the guide rod 16 passes through the adjustable bracket and slides with the adjustable bracket 17, and the two ends of the guide rod 16 are fixedly connected to the fixed plates 13 at the upper and lower ends respectively; Figure 6 As shown, the adjustable bracket 17 is an L-shaped structure, a card slot 171 is provided at the top of the vertical section of the L-shaped structure, and one end of the horizontal section is slidably connected to the linear slide.

The second laser ranging sensor 172 is connected to the controller signal and is used to measure the distance between the adjustable bracket and the positioning plane.

[0046] like Figure 6 As shown, the inner wall of the linear slide is vertically arranged with a plurality of positioning holes (not shown in the figure), and the adjustable bracket 17 is provided with a threaded hole passing through the inner and outer ends of the adjustable bracket, and the threaded hole passes through and is screwed with a positioning screw 173 that cooperates with the positioning hole.

[0047] In this embodiment, one or more high-strength positioning screws 173 can be provided as needed. When secured to the linear chute, the adjustable corbel supports the load of the support beam and the cast crossbeam above it. The linear chute slidably engages with one end of the adjustable corbel, limiting the adjustable corbel to up and down movement and preventing rotation relative to the linear chute. A drive motor is used to drive the adjustable corbel up or down to ensure that the support beam on the slot reaches a specified height. If the intelligent support system slides downward relative to the pile body, the support beam can be reset by adjusting the height of the adjustable corbel after further strengthening the friction between the intelligent support system and the pile body.

The piston rod of the second electric cylinder or the second hydraulic cylinder is connected to the arc-shaped pressure plate three 181 that cooperates with the outer wall of the pile body 1 through the pressure sensor two 182. The inner surface of the arc-shaped pressure plate three 181 is provided with a friction surface three. The control circuit of the second electric cylinder or the second hydraulic cylinder and the pressure sensor two are electrically connected to the controller through wires.

[0050] In this embodiment, the third support structure is used to achieve relative fixation between the mounting seat and the pile body. When the mounting seat and the pile body are relatively fixed, the friction between the arc pressure plate three and the pile body further bears the load borne by the intelligent support system, thereby ensuring the stability of the position of the support beam 19 during the construction process.

The controller judges the connection strength between the mounting seat 12 and the pile body 1 according to the signal of the pressure sensor two, and retracts the first support structure 6. The support ring 5 is raised by the driving mechanism, and after rising by a set distance, the support ring 5 is fixed with the pile body 1 through the first support structure 6. In this way, the above steps are repeated until the first laser ranging sensor 7 detects that the support ring 5 reaches the set height and stops. In the above climbing process, the connecting support beams between the adjacent cantilevers are integrally climbed (i.e. the intelligent support system synchronously climbs to drive the support beam to rise) or, after climbing to the specified height, the adjustable cantilevers are raised to the specified height by rotating the driving motor, and then the support beam is loaded between the clamping grooves of the adjustable cantilevers on the same side by the hoisting equipment (in order to ensure the connection strength, the support beam can be fixedly connected with the clamping groove through bolts);

[0061] (4) The adjustable bracket 17 is fixed relative to the linear slide by tightening the positioning screw, and the guide column and guide sleeve structure is fixed relative to each other by screwing in the positioning bolt; the second support structure on the support ring 5 is tightened, and the support ring and the pile body are dually fixed by the first support structure and the second support structure; similarly, the second support structure on the mounting seat 12 is tightened, and the mounting seat and the pile body are dually fixed by the third support structure and the second support structure on the mounting seat;

[0062] (5) After installing the front and rear support beams 19, lay the bottom formwork for pouring the crossbeams on the support beams 19 (not shown in the figure; in order to ensure the support strength of the bottom formwork, such as Figure 4 As shown, several keels can also be laid in a horizontal direction perpendicular to the support beam 19). During the construction and pouring process, the controller monitors the data of the first laser ranging sensor and the second laser ranging sensor. If the data tends to decrease synchronously, it means that there is a tendency to slide down along the pile body. The force of the first supporting structure and the third supporting structure on the pile body is increased, and the support ring and the second supporting structure on the mounting seat are further tightened. If necessary, the positioning screw is unscrewed, the drive motor is started to raise the adjustable bracket to the original height, and the positioning screw is locked again.

[0063] This embodiment provides the construction method and working principle of the present invention. Compared with the traditional construction method, the present invention can avoid the support beam from sliding down during construction to the greatest extent by setting up multiple friction protections during construction. At the same time, during the construction process, the height of the support beam is monitored in real time. If sliding occurs, it can be interrupted and processed in time. In response to the sliding problem, after the intelligent support system is re-locked with the pile body, the position of the support beam can be quickly adjusted, thereby ensuring the quality of the beam casting and avoiding the hidden dangers caused by the failure of the local support of the bottom formwork. The intelligent support system of the present invention can carry the support beam to climb to a specified height, greatly reducing the construction difficulty and improving the construction efficiency. During the entire construction process, the first and second laser ranging sensors can cooperate with the positioning ring to achieve accurate positioning of the support beam height, avoiding the construction risks caused by manual positioning errors. The present invention actually provides an intelligent robot that can be used for supporting the bottom formwork for the casting of high-pile wharf beams, improving the intelligence level of construction equipment and methods, and having significant technological progress.
