Description

Technical Field

[0001] This utility model relates to the field of building steel cage construction, and in particular to a sliding rod locking positioning hanger for pile hole steel cages. Background Technology

[0002] A pile hole reinforcement cage hanger is a construction device used to accurately and stably lower reinforcement cages into pile holes. Through the positioning and guiding function of the hanger, it ensures that the reinforcement cage is accurately lowered to the center of the pile hole, while preventing instability such as tilting or swaying during the lowering process.

[0003] Utility model patent application CN202420911349X discloses a rebar cage auxiliary installation device with positioning function. The device has a U-shaped hook at the lower end of a vertical rod. After the hook engages the rebar cage, a support rod with a telescopic locking function extends outward, and a pressure block at its lower end presses the rebar cage stirrups onto the hook, thus locking the hook. This hook-and-lock structure, which uses a U-shaped hook to engage the stirrups, suffers from difficulty in retracting the hook during use, resulting in inflexible operation and requiring improvement. Utility Model Content

[0004] To solve the above problems, this utility model proposes a sliding rod locking positioning hanger for pile hole reinforcement cages.

[0005] The technical solution of this utility model is: a sliding rod locking positioning hanger for a pile hole reinforcement cage, including a locking rod and a hanging rod. The upper end of the hanging rod is provided with a hook, and a supporting steel pipe is inserted into the hook. The supporting steel pipe is horizontally supported at the large end of the pile hole. Several sliding sleeves are provided at equal intervals along the length of the hanging rod on the outer side of the hanging rod. The lower end of the hanging rod is provided with an inclined U-shaped rod. The arc end of the U-shaped rod extends outward from the side of the hanging rod. The locking rod is slidably fitted between the sliding sleeves, so that the locking rod can slide along the hanging rod. The sliding direction of the locking rod is consistent with the axial direction of the hanging rod. The axial direction of the locking rod is directly opposite to the internal space of the arc end of the U-shaped rod, and it can slide into the interior of the U-shaped rod.

[0006] Preferably, the lower end of the locking rod is provided with a lower stop block, which is located above the lowermost sliding sleeve. The sliding sleeve is welded to the hanging rod, and the length between the lower stop block and the lower end face of the locking rod is greater than the distance between the sliding sleeve and the arc end of the U-shaped rod.

[0007] Preferably, an upper stop block is provided above the lower stop block. The upper stop block is located below a lower sliding sleeve B. The upper stop block and the lower stop block are the same size. The sliding sleeve B is made of a nut. The length between the upper stop block and the lower end face of the locking rod is less than the distance between the sliding sleeve B and the arc end of the U-shaped rod.

[0008] Preferably, the mounting bracket is U-shaped, with several horizontal bracing rods evenly arranged between the side rods of the U-shaped bracket, and the number of horizontal bracing rods is 3-5.

[0009] Preferably, the upper end of the locking rod is provided with a handle, the main body of which is a ring, a rubber anti-slip sleeve can be fitted on the ring, and a connecting rod fixed to the side of the locking rod is provided on the ring, the connecting rod being welded and fixed to the locking rod along the length direction of the locking rod.

[0010] Preferably, the internal space of the U-shaped rod is larger than the cross-sectional dimension of the locking rod, so that the locking rod can freely enter the U-shaped rod, and a space for fitting a hoop is formed between the locking rod and the U-shaped rod.

[0011] The beneficial technical effects of this utility model are as follows: the hanger is composed of a locking rod and a U-shaped rod bent at the lower end of the hanger rod to form a hook structure. After the locking rod slides into the U-shaped rod, it locks the hoop. After sliding away, the U-shaped rod is in a fully open state and automatically disengages from the hoop. This avoids the problem of difficulty in separating the hoop from the hook, thus improving the flexibility and convenience of use and operation. Attached Figure Description

[0018] Example 1, see appendix Figure 1-5A sliding rod locking positioning hanger for pile hole reinforcement cages includes a locking rod 1 and a hanging rod 2. The cross-sectional dimension of the hanging rod is larger than that of the locking rod. The upper end of the hanging rod 2 is provided with a hanging member. Several sliding sleeves are provided at equal intervals along the length of the hanging rod on the outer side of the hanging rod. The lower end of the hanging rod 2 is provided with an inclined U-shaped rod 21. The arc-shaped end of the U-shaped rod 21 extends outward to the side of the hanging rod 2 and covers the sliding sleeve. Both ends of the U-shaped rod 21 are provided with welded rod segments 22, which are welded and fixed to the side of the hanging rod 2. The locking rod 1 is slidably fitted between the sliding sleeves and can slide freely between the sliding sleeves. The sliding direction of the locking rod 1 is consistent with the axial direction of the hanging rod 2, and the axial direction of the locking rod 1 is directly opposite to the internal space of the arc-shaped end of the U-shaped rod 21.

[0019] The overall shape of the hanger is a U-shaped frame 23. Several horizontal support rods 24 are evenly arranged between the side rods of the U-shaped frame. Different horizontal support rods represent different support heights.

[0020] The upper end of the locking rod 1 is provided with a handle. The main body of the handle is a ring 13. The ring 13 is provided with a connecting rod 14 fixed to the side of the locking rod 1. By holding the handle, the locking rod 1 can be pushed and pulled, so that it slides between the sliding sleeves.

[0021] The internal space of the U-shaped rod 21 is larger than the cross-sectional dimension of the locking rod 1, allowing the locking rod 1 to freely enter the U-shaped rod 21. After entering the U-shaped rod 21, a locking space is formed, and the stirrups 31 of the steel cage 3 are fitted into this locking space.

[0022] The usage method and principle of the hanger in this embodiment are as follows: After the reinforcing cage 3 is suspended into the pile hole 4 by the crane, the U-shaped rod 21 at the lower end of the hanger is pressed against the stirrup 31 of the reinforcing cage 3. The handle is held and the locking rod is pushed down. The locking rod slides down between the sliding sleeves and enters the arc end of the U-shaped rod 21, initially locking the stirrup 31. After the reinforcing cage 3 is completely lowered into place, the hanger is located at the sleeve 41 at the upper part of the pile hole 4. At this time, the hanging steel pipe 5 is inserted between the horizontal support rods 24 of the hanger. The hanging steel pipe 5 is supported at the end of the sleeve 41. The reinforcing cage 3 is in a suspended state. At this time, the self-weight of the reinforcing cage 3 causes the stirrup 31 to be pressed between the locking rod and the U-shaped rod 21. The locking rod is pressed against the side inside the U-shaped rod 21 and is in a fully locked state. When disassembling, the hanging steel pipe 5 is pulled out, the locking rod 1 loses its pressing force, and the locking rod 1 is pulled up to release the locking of the stirrup.

[0023] Example 2, see appendix Figure 1-2This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the lower end of the locking rod 1 is provided with a lower stop block 11, which is located above the lowermost sliding sleeve A 25. The length between the lower stop block 11 and the lower end face of the locking rod 1 is greater than the distance between the sliding sleeve and the arc end of the U-shaped rod 21. This design ensures that when the locking rod 1 extends into the U-shaped rod 21 to lock the hoop, the lower stop block 11 just contacts the sliding sleeve A 25, restricting the locking rod 1 from moving further downward, thus playing a role in locking and limiting downward movement, making the operation more convenient.

[0024] An upper stop 12 is provided above the lower stop 11. The upper stop 12 is located below a lower sliding sleeve 26. The length between the upper stop 12 and the lower end face of the locking rod 1 is less than the distance between the sliding sleeve 26 and the arc end of the U-shaped rod 21. This design ensures that when the locking rod 1 leaves the U-shaped rod 21, the upper stop 12 just contacts the sliding sleeve 26, restricting the locking rod 1 from moving upward and thus locking it to the upper limit, improving the ease of operation.
