[0024] A construction method for an intelligent operation platform 1 for installing high-pile wharf clamps includes the following steps: Step S1, Construction preparation: Set up surveying instruments on the shore, prepare clamp installation tools and clamps, and place them in the work platform 1; Step S2: Equipment debugging and lifting of work platform 1; Step S3, Positioning of working platform 1: The working platform 1 is placed at the pile body of the pile foundation, and the speed of the working platform 1 is slowed down when it is lowered to near the predetermined elevation; Step S4, Pile clamping and chain hoist fine-tuning: After the work platform 1 is in place, the operator sends a pile clamping command to the PLC control module 401 of the PLC control unit 4 via the remote controller 405. The PLC control module 401 receives the command and, based on the feedback signals from the stroke sensor 403 and the pressure sensor 402, controls the hydraulic pump station 201 to drive the hydraulic jack 202 to clamp the pile body, and controls the hydraulic pile clamping device to clamp the pile body. Subsequently, the operator sends a leveling command via the remote controller 405.

[0026] In step S3, after the work platform 1 is positioned, the crawler crane is unloaded but the boom is kept extended to prevent the work platform 1 from falling.

[0027] In step S3, for a straight pile, the work platform 1 is moved to the top of the pile by the crawler crane, closely approaches the pile body in a vertical lowering manner, the length of the chain of the electric cable chain 303 is adjusted, the chain is hung and stressed, and then the hydraulic pile clamping device is driven to clamp the pile body of the pile foundation.

[0028] In step S3, for an inclined pile, the angle of the boom is adjusted to make the inclination direction of the work platform 1 consistent with the inclination angle of the pile body, the work platform 1 is slowly approached from the side of the pile body to ensure stable contact, the length of the chain of the electric cable chain 303 is adjusted to make the work platform 1 horizontal, and then the hydraulic pile clamping device is driven to clamp the pile body of the pile foundation.

[0029] In step S4, after the work platform 1 is positioned, the platform elevation is calibrated, and the platform elevation is calibrated to the hoop installation elevation plus 10-20 cm to reserve installation space.

[0030] In one specific embodiment, the assembly and preparation of the work platform 1: the assembly of the work platform 1 is completed in the land precast yard, the work platform 1 is made of profile steel welding, the fixed guardrail 102 is installed on the base 101, the preset butt joint opening 105 is provided on the base 101, the movable guardrail 103 that can be opened and closed is provided on the fixed guardrail 102, and the layable foot pad 104 is provided on the base 101; Install the hydraulic pile clamping unit 2: install the hydraulic pump station 201 on the base 101 of the work platform 1, arrange two pairs of hydraulic jacks 202 symmetrically at the bottom of the base 101, connect the hydraulic jacks 202 with the hydraulic pump station 201 through high-pressure oil pipes, Install the inverted chain lifting unit 3: place the top tray 301 above the center of the base 101, weld four hanging rods 302 on the top tray 301, weld an ear 305 at the top center of the top tray 301, and hang four electric inverted chains 303 with a rated lifting capacity of 3 tons on the four hanging rods 302 respectively, and the hooks 304 of the electric inverted chains 303 are connected with the lifting plate 5 of the working platform 1; PLC control unit 4: the pressure sensor 402 is arranged inside the hydraulic pump station 201, the stroke sensor 403 is arranged on the hydraulic jack 202, the PLC control module 401 is electrically connected with the pressure sensor 402, the stroke sensor 403, the hydraulic pump station 201 and the electric inverted chain 303, the PLC control module 401 receives and processes the signals of the pressure sensor 402 and the stroke sensor 403, and controls the hydraulic pump station 201 to drive the hydraulic jack 202 to act based on the processing result; the PLC control module 401 receives the wireless instructions from the remote controller 405 and controls the synchronous lifting of the electric inverted chain 303 accordingly, and the power supply 404 provides power for the working platform 1, the hydraulic clamp pile unit 2, the inverted chain lifting unit 3 and the PLC control unit 4.

[0031] Construction preparation and lifting: erect surveying instruments such as total station on the shore, and place wrenches, bolts, tools and materials such as hoops to be installed in the working platform 1 in advance, the operator enters the platform and fastens the safety belt. The main hook of the crawler crane hooks the lifting lug 305 of the top tray 301, lifts the whole working platform 1 stably, and stops at a height of 2 meters from the ground, checks the sling and the stability of the platform, and continues to lift after confirming that there is no error; Platform positioning and intelligent leveling: for straight piles, the crawler crane is commanded to move the platform to directly above the pile, and slowly vertically lower it, and when the bottom of the platform is lowered by about 10-20 cm below the design installation elevation of the hoop, the speed is slowed down, and finally the pile body is lightly contacted. For inclined piles: the crawler crane needs to adjust the angle of the lifting arm to slowly approach the working platform 1 from the side of the pile body to ensure stable contact.

[0032] Subsequently, the operator issues a "pile clamping" instruction through the remote controller 405, the PLC control module 401 receives the instruction, starts the hydraulic pump station 201, and automatically controls the hydraulic jack 202 to push the clamping piece 203 according to the real-time feedback of the stroke sensor 403 and the pressure sensor 402, until the preset clamping force and stroke are reached, and the working platform 1 is tightly clamped on the pile body of the pile foundation; Closed-loop lifting and precise positioning: After the pile is clamped and stabilized, the operator sends a "lifting" or "leveling" command through the remote controller 405, and the PLC control module 401 controls the synchronous operation of the four electric cable winches 303. For inclined piles, the PLC control module 401 receives the level signal and differentially controls the lifting length of each cable winch, i.e. the cable winch on the inclining side is retracted and the cable winch on the back inclining side is extended, automatically adjusting the work platform 1 to an absolutely horizontal state. This process realizes the fine adjustment and precise positioning of the platform height, creating a stable work surface for subsequent installation. Safety protection and hoop installation: After the platform is leveled and stabilized, the operator lays the footboard 104 on the open side and closes the movable guardrail 103, forming a closed and safe working space. At this time, the crawler crane can be completely unloaded, but the hook should be kept slightly tensioned as an additional precaution. The shore-based measurement personnel command the platform operator to accurately mark the hoop installation position on the pile using instruments. The operator assembles the hoop, threads the bolts, and tightens them using a torque wrench according to the specified torque.

[0033] Work platform 1 transfer: After installation is complete, the operator sends a "pile release" command through the remote controller 405, and the PLC control module 401 controls the hydraulic jack 202 to retract and release the pile. The operator then folds up the footboard 104 and opens the movable guardrail 103. Subsequently, the crawler crane slowly lifts the platform and moves it to the next pile, repeating the above steps.

[0034] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
