The pile of prefabricated piles 4 is a kind of pile of prefabricated piles 4, and the ... The unhooking elevator 2 is connected to the corresponding semicircular hoop in a clamping manner. The wedge-shaped self-unhooking elevator 2 is used to facilitate the connection between the lifting cable 5 and the adjustable hoop assembly 1, which facilitates the subsequent lifting and transportation of the precast pile 4.

In actual applications, the outer guard plate 112, the inner guard plate 113, and the side guard plate 114 can be fixedly connected by welding.

[0042] On the basis of the above embodiments, the specific implementation of the adjustment component 111 is as follows: the adjustment component 111 includes a fixed seat, an adjustment screw 1110, and a horizontal adjustment shaft 1111. The fixed seat is fixedly arranged at the top of the arc of the corresponding outer guard plate 112. The horizontal adjustment shaft 1111 is rotatably arranged in the fixed seat through a fixed bearing 1115 and a fixed bearing 2 1116. The fixed bearing 1115 and the fixed bearing 2 1116 are relatively arranged in the fixed seat left and right. The adjustment screw 1110 is fixedly arranged at one end of the horizontal adjustment shaft 1111, and the adjustment screw 1110 is located outside the fixed seat. In actual applications, the rotation of the horizontal adjustment shaft 1111 is achieved by rotating the adjustment screw 1110. Specifically, the adjusting screw 1110 is a bolt, and the adjusting screw 1110 can be driven to rotate by using a wrench. The transmission assembly includes a transmission bevel gear 1112, a transmission bevel gear 2 1113, a vertical adjustment shaft 1114, an adjustment gear 117, an adjustment gear 2 118, a gear shaft 1133, and a rotating gear plate 115.

The transmission bevel gear 2 1113 is arranged on the vertical adjustment shaft 1114, and the transmission bevel gear 1113 is meshed with the transmission bevel gear 2 1114. The rotation of the horizontal adjustment shaft 1111 realizes the rotation of the vertical adjustment shaft 1114. The adjusting gear 117 is fixedly arranged on the vertical adjustment shaft 1114 and the adjusting gear 1117 is located between the inner guard plate 113 and the outer guard plate 112. The two gear shafts 1133 are fixedly arranged between the base 1122 and the base 2 1132 and the two gear shafts 1133 are located on both sides of the vertical adjustment shaft 1114. An adjusting gear 2 118 is rotatably arranged on each of the gear shafts 1133, and the adjusting gear 2 118 is meshed with the adjusting gear 1 117. The rotation of the vertical adjustment shaft 1114 realizes the rotation of the two adjusting gears 2 118 through the transmission of the adjusting gear 1 117.

When the two adjusting gears 2 118 rotate under the drive of the same adjusting gear 1 117,The two rotating gear plates 115 perform circular motions in opposite directions, that is, when one rotating gear plate 115 moves clockwise, the other rotating gear plate 115 moves counterclockwise. The fixed clamping plate 116 is sleeved in the inner guard plate 113. The rotation of the rotating gear plate 115 can drive the corresponding fixed clamping plate 116 to perform telescopic motion along the radial direction of the inner guard plate 113. The specific implementation method of converting the circular motion of the rotating gear disc 115 into the telescopic motion of the corresponding fixed clamping plate 116 is as follows: the arc plate 1161 at the outer end of the fixed clamping plate 116 is located on the outer side of the inner guard plate 113, and an arc clamping plate 1161 and a radial slide rail 1162 are respectively arranged at the inner end of the fixed clamping plate 116, and an arc slot 1151 corresponding to the arc clamping plate 1161 is arranged on the corresponding rotating clamping plate 115, and the arc clamping plate 1161 is clamped in the corresponding arc slot, and the distance from the upper end to the lower end of the arc slot 1151 to the center of the rotating gear disc 115 is 1. The distance gradually changes from small to large. When the arc-shaped clamping plate 1161 is located at the lower end of the arc-shaped slide groove 1151, the fixed clamping plate 116 is in the retraction limit position. When the arc-shaped clamping plate 1161 is located at the upper end of the arc-shaped slide groove 1151, the fixed clamping plate 116 is in the extension limit position. A slide groove 1140 corresponding to the radial slide rail 1162 is provided on the corresponding side guard plate 114. The radial slide rail 1162 is sleeved in the slide groove 1140. The radial slide rail 1162 is guided by the slide groove 1140, so that the fixed clamping plate 116 can smoothly realize radial movement. In practical applications, the number of fixed clamps 116 on each semicircular clamp is set to two, and the two fixed clamps 116 are symmetrically distributed along the circumferential direction of the inner guard plate 113. After the two semicircular clamps are clamped on the periphery of the precast pile 4, the two adjusting screws 1110 are synchronously rotated to make the four fixed clamps 116 constantly approach the outside of the precast pile 4, and then finally realize the clamping and fixing of the fixed clamps 116 to the precast pile 4. When the clamping and fixing of the precast pile 4 needs to be released, the fixed clamps 116 are retracted relatively away from the precast pile 4 by rotating the adjusting screws 1110, so as to realize the release of the clamping and fixing of the precast pile 4 by the fixed clamps 116.

[0043] On the basis of the above-mentioned embodiment, the specific implementation method of achieving stable clamping of the two semicircular clamps distributed up and down is as follows: an upper clamping platform is fixedly provided on the left and right sides of the outer guard plate 112 located on the upper side, and a lower clamping platform is fixedly provided on the left and right sides of the outer guard plate 112 located on the lower side, and the upper clamping platform and the corresponding lower clamping platform are correspondingly distributed up and down, and a wedge-shaped clamping groove 1121 is provided on the upper end surface of the upper clamping platform and the lower end surface of the lower clamping platform, and a dovetail groove 1123 is provided on the lower end surface of the upper clamping platform, and a dovetail linear guide 1120 corresponding to the dovetail groove 1123 is provided on the upper end surface of the lower clamping platform, and the dovetail linear guide 1120 is sleeved in the corresponding dovetail groove 1123. When the dovetail linear guide 1120 is inserted into the corresponding dovetail groove 1123, the upper clamping platform and the lower clamping platform are docked, thereby realizing the docking connection of the two semicircular clamps.

[0044] On the basis of the above-mentioned embodiment, a specific implementation method of realizing the clamping of the semicircular clamp after docking by using a wedge-shaped self-unhooking elevator is as follows: the wedge-shaped self-unhooking elevator 2 includes a clamping box 21 and a suspension rod 22, the interior of the clamping box 21 is hollow and its front and right sides are in an open state, the lower part of the suspension rod 22 is rotatably connected to the clamping box 21, specifically, a bearing 23 is provided on the left side wall of the clamping box 21, the lower end of the suspension rod 22 is fixedly connected to the inner end of the bearing 23, the rotation of the inner ring of the bearing 23 is utilized to realize the free rotation of the suspension rod 22, a lifting ring 220 is fixedly provided on the upper part of the suspension rod 22, and the lifting ring 220 is utilized to facilitate the realization of the suspension rod 22 is connected with the lifting cable 5, and two wedge-shaped blocks 211 are arranged in the clamping box 21. Specifically, the two wedge-shaped blocks 211 are respectively distributed at the bottom of the upper side wall and the upper part of the lower side wall of the clamping box 21, and the two wedge-shaped blocks 211 correspond to two wedge-shaped slots 1121 distributed up and down. After the clamping box 21 is put on the outer sides of the upper clamping platform and the lower clamping platform corresponding to the upper and lower clamping platforms, when the inner side of the rear side wall 212 of the clamping box 21 is fitted with the side walls of the upper clamping platform and the lower clamping platform, a self-detachment gap 1124 is reserved between the outer side wall of the wedge-shaped block 211 and the inner side wall of the corresponding wedge-shaped slot 1121. When the present invention is used to vertically hoist the precast pile 4, when it is necessary to remove the wedge-shaped self-detaching hook elevator 2 from the outside of the semicircular clamp, after the bottom of the precast pile 4 contacts the ground, the hoisting cable 5 continues to be lowered. During the lowering process of the hoisting cable 5, due to the existence of the self-detaching gap 1124, the wedge-shaped clamping block 211 can smoothly slide out of the wedge-shaped clamping groove 1121 under the action of gravity, thereby realizing the separation of the wedge-shaped self-detaching hook elevator 2 from the semicircular clamp. During the vertical hoisting process, when the rear side wall of the clamping box 21 is broken, the wedge-shaped clamping block 211 will continue to move upward and be clamped in the wedge-shaped clamping groove 1121. The wedge-shaped clamping groove 1121 is used to limit the wedge-shaped clamping block 211, which effectively prevents the wedge-shaped self-detaching hook elevator 2 from being separated from the semicircular clamp, thereby improving the hoisting safety of the precast pile.
