The cover 601 that induced drafts fixed mounting is on support frame 201 rear end face upper portion, and the cover 601 that induced drafts is circular box-shaped structure, and the cover 601 internal rotation that induced drafts is connected with a drive shaft 604, and the drive shaft 604 front end runs through the cover 601 that induced drafts and is equipped with driven drive, and the drive shaft 604 rear end is located the cover 601 internal mounting that induced drafts and has four fan blades 605 to when fan blade 605 is rotatory, can make the inside rear end of cover 601 that induced drafts produce suction. Four air outlet holes are formed in the upper portion of the front end face of the air suction cover 601, four air outlet pipes are fixed to the position, located at the air outlet holes, of the front end face of the air suction cover 601 and used for guiding sucked air flow, an air conveying pipe fitting 602 is connected to the front ends of the four air outlet pipes, and an air blowing pipe fitting 603 is connected to the lower portion of one end of the air conveying pipe fitting 602. Blowing pipe 603 is arc tubular structure, and is even form on the concave surface of blowing pipe 603 bottom and has seted up six holes of blowing to it is more even when blowing to make blowing pipe 603, thereby makes wire rope and pulley 202 friction department obtain effectual cooling effect. When the airflow cooling portion 6 and the support rod 2 are in the installation state, the driven pulley at the front end of the driving shaft 604 is in transmission connection with the driving pulley 203 through a belt, and the diameter of the driven pulley is five times to seven times of the diameter of the driving pulley 203, so that a large transmission ratio is provided between the driven pulley and the driving pulley 203, and the driven pulley is more efficient when driving the driving shaft 604 to rotate.

Referring to fig. 9 and 10, the insertion part 9 includes an insertion slide case 901, an insertion slider 902, a pulling rod 903, and a stopper plate 904. The plugging sliding shell 901 is fixed on the upper end face of the supporting sliding barrel 801, a plugging sliding block 902 slides inside the plugging sliding shell 901, an insertion rod penetrating through the bottom of the plugging sliding shell 901 is fixed on the bottom end face of the plugging sliding block 902, and a pulling rod 903 penetrating through the top of the plugging sliding shell 901 is arranged on the upper end face of the plugging sliding block 902 and used for pulling the plugging sliding block 902 upwards, so that the insertion rod can be pulled out from a limiting jack on the telescopic supporting rod 802. The outside of the pulling rod 903 is located inside the splicing sliding shell 901 and is sleeved with a spring, the upper end of the pulling rod 903 is rotatably connected with a handle, the upper end face of the splicing sliding shell 901 is located on the left side and the right side of the handle and is provided with a limiting plate 904, and the middle parts of the upper end faces of the two limiting plates 904 are provided with limiting notches for limiting a handle pulled upwards.

In another embodiment, two limiting sliding sleeves are arranged outside the steel wire rope connected between the pile driving head 4 and the winding device 3 in a sliding manner, and are fixed in the middle of the upper end of the support frame 201, and the two limiting sliding sleeves are arranged on the upper end of the support frame 201 in a bilateral symmetry manner, so that the steel wire rope connected between the pile driving head 4 and the winding device 3 is not easily separated from the pulley 202 during sliding.

When the invention is used: when the pile driving head 4 drives the pile, firstly the steel wire rope is loosened by the winding device 3, then the pile driving head 4 drives the left end of the steel wire rope to rapidly move downwards under the action of gravity, then the upper end of the pile is hammered downwards through the bottom end face of the pile driving head 4, and the left end of the steel wire rope moves downwards and drives the two pulleys 202 to rotate anticlockwise, then the two driving pulleys 203 are driven to rotate anticlockwise, so that the two driving pulleys 203 drive the two driven pulleys to rotate through the belt, then the driving shaft 604 drives the suction fan blade 605 to rotate, so that the suction force is generated at the rear side inside the suction hood 601, then the external air flow is transmitted to the inside of the air delivery pipe 602, and then is blown out to the outside of the pulley 202 and the steel wire rope through the blowing holes at the bottom of the blowing pipe 603, thereby effectively cooling the steel wire rope which is rapidly in sliding friction with the pulley 202;

when the pile driver is in maintenance, a maintainer climbs the ladder climbing piece 5, firstly ties the binding waistband 7 at the waist, then the maintainer drives the binding belt 7 to move upwards through the body in the process of climbing upwards, then the waistband 7 is tightly bound to drive the sliding block 503 and the sliding sleeve to move upwards, then the limit inserting block 1003 sequentially slides through the rectangular slot 502 through the round angle at the upper side of the limit inserting block 1003, then when the maintainer steps on the ground, the tying waistband 7 is driven by the body to fall down rapidly, then the sliding block 503 and the sliding sleeve are driven to move downwards by tightening the waistband 7, and when the limit inserting block 1003 slides downwards, the rectangular sliding block 1002 will push the limiting insert 1003 into the rectangular slot 502 under the action of the spring, so that the rectangular sliding block 1002 is limited, so that the sliding block 503 cannot move downwards, and then the maintainer can be pulled by tightening the waistband 7.
