Pore-forming detection device and probe extending-retracting mechanism thereof

Abstract

The invention discloses a pore-forming detection device and a probe extending-retracting mechanism thereof. A lifting mechanism comprises a rack and a probe. A winding reel, a wire arranging mechanism, a first pulley and a second pulley are arranged on the rack, a third pulley is arranged on the upper side of the probe, and the first pulley, the second pulley and the third pulley are arranged in the same vertical plane. The winding reel is wound with a cable, one end of the cable is electrically connected with a control cabinet, and the other end of the cable is fixed and electrically connected with the probe through the first pulley, the third pulley and the second pulley in sequence. The lifting mechanism is provided with a pulley mechanism and adopts the cable to be matched with the pulley mechanism to extend and retract the probe stably. Compared with the existing device for synchronously controlling lifting by combining the cable with a steel wire rope, the extending-retracting operation is more convenient to control, and the tilt phenomenon caused by the improper extending-retracting cooperation of the cable and the steel wire rope cannot occur. Moreover, the volume and weight of a winch can be reduced greatly, the winch structure can be simplified, and the failure rate is reduced.

Description

technical field [0001] The invention relates to the field of hole-forming detection, in particular to a hole-forming detection device and a probe retractable mechanism thereof. Background technique [0002] National or local engineering construction specifications require that the quality of the formed pile hole (groove) should be inspected before pouring concrete to prevent the verticality and diameter (width) error of the hole (groove) from exceeding the specification index. [0003] In the existing scheme, the winch for lifting the probe usually uses two steel wire ropes as the load-bearing unit, and one signal cable as the signal transmission and power supply unit. Mechanism for cross arm balance. Due to bearing the weight of the probe and keeping the balance of the probe at the same time, generally the steel wire rope will be neatly wound on the winch drum in order, and the cables need to be wound neatly and single-row on the roll because they need to keep in sync with...

AI Technical Summary

Problems solved by technology

Due to bearing the weight of the probe and keeping the balance of the probe at the same time, generally the steel wire rope will be neatly wound on the winch drum in order, and the cables need to be wound neatly and single-row on the roll because they need to keep in sync with the steel wire rope, so the overall volume of the winch is large and the weight is heavy. Very heavy, each winch weighs about 150Kg, and it needs four people to lift it to the detection position
