[0032] Reference Figures 1-4 A chain type positioning equipment, comprising: a plurality of bases 1, moving blocks 3, moving rods 4, limiting chains 5 and adjusting assemblies and other parts.
[0033] Firstly, a plurality of bases 1 are prepared, which are arranged in pairs, and each pair of bases 1 is located on both sides of the precast pile and cooperates with each other to stabilize the support. On the top of each base 1, two moving blocks 3 are installed through a sliding mechanism, and the top of the moving block 3 is fixedly installed with a moving rod 4. The moving rod 4 is provided for subsequent connection with the limiting chain 5.
[0034] Next, at least two limiting chains 5 are arranged between each pair of bases 1, which are respectively located on both sides of the precast pile to ensure the omnidirectional positioning of the precast pile. The limiting chain 5 is connected by a plurality of chain links 6 in sequence, each chain link 6 includes a mounting ring 7, a first connecting ear 8 and a second connecting ear 9. The first connecting ear 8 and the second connecting ear 9 are respectively fixed on both sides of the mounting ring 7, and are connected with the second connecting ear 9 and the first connecting ear 8 of the adjacent chain link 6 through rotary connection, forming a flexible chain structure. The mounting ring 7 is rotatably provided with a ball 10 inside, and the outer wall of the ball 10 is closely fitted with the outer wall of the precast pile to reduce friction and provide stable support.
[0035] In order to realize the mutual approach and away of the two moving rods 4 on the same base 1, a plurality of adjusting assemblies are provided in the embodiment. Each adjusting assembly includes two fixed plates 2 fixedly installed on the top of the base 1, and a double-threaded screw rod 13 rotatably connected between the two fixed plates 2. One end of the double-threaded screw rod 13 penetrates through one of the fixed plates 2 and extends out, and a motor 14 is fixedly installed on the top of the base 1, and the output shaft of the motor 14 is fixedly connected with one end of the double-threaded screw rod 13 extending out. The two threads of the double-threaded screw rod 13 are opposite in direction and are respectively threadedly connected with the two moving blocks 3, so that when the motor 14 drives the double-threaded screw rod 13 to rotate, the two moving blocks 3 will move along the double-threaded screw rod 13 to realize the mutual approach or away.
[0036] In the embodiment, the connection mode of the limiting chain 5 and the moving rod 4 is further optimized. Specifically, two installation grooves 15 are formed on the outer wall of each moving rod 4, and the installation grooves 15 penetrate the top end of the moving rod 4. The two ends of the limiting chain 5 are rotatably connected with a connecting rod 16, and the other end of the connecting rod 16 is fixedly installed with a limiting block 17.

The ball 10 is limited in the rotating direction by the sliding cooperation of the limiting sliding groove 12 and the limiting strip 11, so that it can only roll along the predetermined track, and the precast pile can only move up and down to complete the stable positioning of the precast pile when the precast pile is positioned.
[0041] In addition, a thread is formed on the top end of the moving rod 4, and an end cover 18 is threadedly connected, which is used to block and fix the connecting rod 16 slidingly arranged in the mounting groove 15, so as to prevent it from falling off.
[0042] Finally, in order to ensure the stability of the base 1 on the ground, two limiting holes are formed near the two ends of each base 1, which are matched with the fixing screws, so that the base 1 can be firmly fixed on the ground by tightening the fixing screws, thereby providing a stable support foundation for the entire positioning device.
