Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction technology, specifically a pile foundation steel cage hoisting and connection device. Background Technology

[0002] The hoisting of the pile foundation reinforcement cage is a crucial step in concrete structure construction, typically used in pile foundation engineering. During the hoisting process, a crane is used to connect the boom to the reinforcement cage, and then the crane is operated to hoist the pile foundation reinforcement.

[0003] Chinese Utility Model Patent Publication No. CN217758788U discloses a hoisting device for a pile foundation reinforcement cage. The device includes a support frame placed on the ground, a clamping assembly for holding the reinforcement cage on the support frame, and a lifting drive component on the support frame. The output end of the lifting drive component is connected to the clamping assembly, driving the clamping assembly to move towards or away from the ground. The clamping assembly includes a sliding drive component and two clamping rods. The output end of the lifting drive component is connected to the sliding drive component via a support frame. The output shafts at both ends of the sliding drive component are respectively connected to the clamping rods, driving the two clamping rods to move simultaneously towards or away from the center of the sliding drive component. This application has the effect that the reinforcement cage is less likely to tilt during hoisting, i.e., less likely to damage the pile foundation hole.

[0004] However, the device still has some problems. One issue is that "after a steel bar on the steel cage is placed on the receiving block, the push spring 7 pushes the abutment plate 6 towards the receiving block 5 until the abutment plate 6 abuts against the side of the steel bar away from the receiving block 5 to fix the steel cage." This fixing method uses the elasticity of the push spring 7 combined with the squeezing effect of the abutment plate 6 on the steel bar to fix it. However, in actual use, the inertia of the horizontal movement of the steel cage will generate an external force that causes the push spring 7 to compress. When the push spring 7 is compressed, the abutment plate 6 will move, causing the part of the steel cage hoisting and connecting to shake, resulting in unstable connection and increasing construction risks. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting and connection device for pile foundation steel cages to solve the problems mentioned in the background art.

Secondary fixing blocks are fixedly installed on one side of the two sliders respectively, and drive units are rotatably installed on the opposite surfaces of the two base frames.

[0007] Preferably, the drive unit includes a bidirectional lead screw, which is rotatably mounted on the opposite surfaces of two base frames (1), and the two moving blocks are correspondingly screwed onto the surface thread areas of the two bidirectional lead screws.

[0008] Preferably, the drive unit further includes a worm gear, and the same hanger is fixedly installed on the upper side of the two base frames. A drive hole is opened on the upper side of the hanger, and the worm gear is rotatably installed in the drive hole. A worm wheel is fixedly installed on the non-threaded area of ​​the surface of the bidirectional lead screw, and the worm wheel meshes with the worm gear.

[0009] Preferably, a drive rod is rotatably mounted on the inner wall of the worm gear, a first-stage bevel gear is fixedly mounted on the bottom end of the drive rod, a transmission rod is rotatably mounted on the inner wall of the protective box, a second-stage bevel gear is fixedly mounted on the surface of the transmission rod, and the first-stage bevel gear meshes with the second-stage bevel gear.

[0010] Preferably, a rotating disk is fixedly installed at the top of the drive rod, and a slot is formed on the surface of the rotating disk. Reinforcing ribs are installed on both the base frame and the hanger. A threaded hole is formed on the upper side of the reinforcing rib, and a positioning rod is screwed into the threaded hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model involves manually rotating a worm gear, which drives a worm wheel to rotate. The worm wheel then drives a double-acting screw to rotate, which in turn drives two moving blocks closer together. The positioning rod is then manually rotated to detach it from the hanger and unlock the rotating disk. One hand holds the worm gear to keep it stationary while the other hand rotates the rotating disk. The rotating disk drives a drive rod, which in turn drives a primary bevel gear. This primary bevel gear drives a secondary bevel gear, which in turn drives a transmission rod. The transmission rod then drives a drive gear, which in turn drives two racks to move closer together. Each rack drives a slider, which in turn moves two secondary fixed blocks away from each other and closer to their corresponding primary fixed blocks. This process compresses and fixes the reinforcing steel between the primary and secondary fixed blocks, enhancing the stability of the connection and improving construction safety.

[0013] 2. In this utility model, the slot on the rotating disk is aligned with the threaded hole by manually fine-tuning the drive rod, and the positioning rod is screwed into the threaded hole to limit the slot and position the drive rod to prevent it from rotating, thereby improving the stability of the connection.
