[0002] H-shaped steel plays a role in bearing in the construction process, and its unique structure can simply and conveniently splice various components, thereby accelerating the construction speed and shortening the construction period. In order to reduce the engineering cost, in the soil mixing wall (SMW) method, the H-shaped steel implanted in the method pile is usually pulled out for reuse.

[0003] In the prior art, the H-shaped steel in the SMW method pile is mainly disassembled by a pile pulling machine. The common pile pulling machine mainly comprises a rack, a hydraulic driving mechanism and a positioning mechanism mounted on the rack, a clamping mechanism fixedly installed at the driving end of the hydraulic driving mechanism, and the clamping mechanism is arranged above the positioning mechanism. In the actual pile pulling construction process, the operator fixes the rack on the ground beside the drill hole in advance, clamps the end of the H-shaped steel through the clamping mechanism, repeatedly lifts the H-shaped steel through the hydraulic driving mechanism, clamps the H-shaped steel through the positioning mechanism when the hydraulic driving mechanism reaches the maximum lifting height, so that the H-shaped steel is kept at the current height, and the H-shaped steel is pulled out through multiple strokes.

[0004] However, after the H-shaped steel is pulled out, a large amount of dust and soil is often attached to the surface of the H-shaped steel, and the operator often needs to clean the H-shaped steel when recycling the H-shaped steel, and the H-shaped steel cannot be cleaned during the process of pulling out the H-shaped steel, which needs to be improved.

[0014] The single-chip microcomputer is signal-connected with the signal output end of the ultrasonic ranging sensor, is used to receive the inductive distance signal, and continuously outputs a second high-level signal when the inductive distance changes.

[0015] The AND gate chip is signal-connected with the signal output ends of the infrared opposite transmission sensor and the single-chip microcomputer, is used to receive the first high-level signal and the second high-level signal and output the trigger signal.

When the H-shaped steel is paused, the single-chip microcomputer does not output the second high-level signal, the AND gate chip does not output the trigger signal, and the cleaning mechanism is not started at this time, so that the consumption of electric energy can be effectively saved.

[0017] Preferably, four connecting seats are fixedly installed on the rack, the cleaning mechanism comprises four servo motors which are respectively adjustably installed on the connecting seats, and the driving ends of the four servo motors are respectively detachably installed with cleaning sponges.

[0018] The signal input ends of the four servo motors are signal-connected with the signal output end of the AND gate chip, the four servo motors receive the trigger signal and respectively drive the cleaning sponges to rotate on the surface of the H-shaped steel.

[0019] The servo motor drives the cleaning sponge to rotate on the surface of the H-shaped steel, and the impurities and dust attached to the surface of the H-shaped steel can be swept away, thereby achieving the technical effect of cleaning the H-shaped steel.

[0020] Preferably, four sliding seats are respectively slidably arranged on the four connecting bases, and the four servo motors are respectively detachably arranged on the four sliding seats.

[0021] Four adjusting screws are respectively threadedly connected to the four connecting bases, and the ends of the four adjusting screws each include a top rod.

[0022] By adjusting the adjusting screws, the position of the servo motor and the cleaning sponge can be adjusted according to the size of the H-shaped steel, so that the cleaning mechanism can be suitable for cleaning H-shaped steels of different sizes, and the usability of the cleaning mechanism can be further improved.

[0023] Preferably, two vertical plates are fixedly arranged on each connecting base, a guide rod is fixedly arranged between the two vertical plates, and a sliding hole is formed in each sliding seat.

[0024] A spring is coaxially arranged on each guide rod, and the spring is located on the side of the sliding seat away from the adjusting screw and abuts against the vertical plate and the sliding seat.

[0025] By adopting the above technical scheme, the position of the sliding seat can be limited by the guide rod, so that the sliding seat can move along the axial direction of the guide rod towards the direction of approaching or moving away from the H-shaped steel.

[0026] In summary, the SMW method pile pulling device has at least one of the following beneficial technical effects:

[0027] 1. The servo motor drives the cleaning sponge to rotate on the surface of the H-shaped steel, and the impurities and dust attached to the surface of the H-shaped steel can be swept away, thereby achieving the technical effect of cleaning the H-shaped steel.
