Description

Technical Field

[0001] This utility model relates to the field of construction hoisting and lifting, specifically a hoisting structure for large culverts. Background Technology

[0002] Currently, the methods used for hoisting large culverts include: oblique hoisting and straight hoisting. In the oblique hoisting method, the culvert is tied in a horizontal position and can be lifted directly from inside without turning it over. After lifting, the slings are at the center of the culvert, allowing for a smaller lifting height, but alignment is inconvenient, and the center of the culvert must have sufficient bending resistance. In the straight hoisting method, the culvert must be turned over before hoisting. After lifting, the culvert is in an upright position, and the crane hook must extend beyond the top of the culvert. The slings are on both sides of the culvert, requiring a spreader bar. The required lifting height is greater than in the oblique hoisting method. The culvert has greater rigidity and enhanced bending resistance after being turned over. However, the culvert is perpendicular to the trench during hoisting, making alignment more difficult. Conventional culvert hoisting places high demands on the bending and flexural strength of the components. Improper use of hoisting points during the hoisting process can easily damage the components, make it difficult to align the culvert components, and result in poor safety performance during hoisting. The culvert may roll due to external forces, which can lead to waste of labor and materials and affect the construction progress.

[0003] Because of the many drawbacks of the above-mentioned methods, we explored new construction methods during construction and adopted a large pipe culvert hoisting construction method with a sealed structure, a balance beam, and an additional safety hook to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a hoisting structure and hoisting method for large pipe culverts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hoisting structure for a large pipe culvert includes a balance beam, slings, a guide rail, and the pipe culvert itself.

[0007] The balance beam has a trapezoidal structure and is symmetrical from left to right. A hoisting hole is opened in the middle of the balance beam, and symmetrical reinforcing ribs A and B are set on both sides. A balance ruler is set at the bottom, and a secondary ruler is symmetrically set on the lower part of the balance ruler. Multiple hanging holes are opened on the secondary ruler for connecting slings.

[0008] The sling includes a U-shaped ring and a steel wire rope. The U-shaped ring is equipped with a sling pin and is used to connect the steel wire rope. The steel wire rope is divided into three sections, which are separated by two steel wire rope clamps. The upper and lower sections are double-layered steel wire ropes, and the middle section is a single-layered steel wire rope. The lower part of the steel wire rope is connected to a fixing pin.

[0009] The hook ruler is generally hook-shaped, with a lifting hole at the top and a horizontal auxiliary component in the middle, on which a fixing bolt is provided.

[0010] The culvert is composed of multiple culvert units connected together. Each culvert unit is cylindrical. The left end of each culvert unit has a connecting section that is lower than the outer diameter of the culvert. The end face of the connecting section is coated with a rubber sealing structure A. The right end of the culvert unit has a connecting groove. The end face of the connecting groove is coated with a rubber sealing structure B. Rubber sealing structures A and B have mutually cooperating grooves and protrusions, respectively. The culvert has lifting pin holes at both ends of the radial direction in the middle. The upper end of the lifting pin hole has a threaded structure and a water-stop ring in the middle.

[0011] The balance beam is connected to the crane hook through the lifting hole. The tethering holes at both ends of the balance beam are connected to the U-shaped rings of the slings through sling pins. The two slings are respectively threaded to the lifting pin holes at both ends of the culvert through fixing pins. The upper axial end of the culvert is connected to the third sling through a hook ruler. The third sling is connected to the crane auxiliary hook.

[0012] Furthermore, the balance beam is made of steel.

[0013] Furthermore, the culvert is placed between the bottom of the hook gauge and the fixing bolt, and the fixing bolt is used to adjust the distance between the lower part of the hook gauge and the fixing bolt.

[0014] Furthermore, the steel wire rope is made of galvanized material.

[0015] Furthermore, the main body of the culvert is made of reinforced concrete.

[0016] During construction, a balance beam, slings, a sling, and a culvert are fabricated as required. The balance beam is attached to the crane hook via a lifting hole. Both ends of the balance beam are connected to the sling pins via attachment holes. The threaded end of the sling's fixing pin is then inserted into the lifting pin hole of the culvert and threadedly connected to the threaded structure, making the lifting more stable. The sling is attached to the crane's auxiliary hook via a third sling. The culvert is placed between the bottom of the sling and the auxiliary components, and the distance is adjusted and fixed using fixing bolts. The fixing bolts are tightened to secure the culvert to the sling, increasing lifting capacity and making the lifting more stable.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention utilizes a threaded fixing pin that connects to a threaded lifting hole on the culvert, ensuring the pin is securely fixed to the culvert. Simultaneously, a hook ruler is attached to the front end of the culvert using a crane's auxiliary hook, resulting in a more stable and efficient lifting process. Furthermore, the rubber sealing structures at both ends of the culvert, the water-stop rings in the lifting holes, and the reinforced concrete used for the culvert walls significantly improve construction quality.

The upper end of the lifting pin hole 42 has a threaded structure 421 and a water-stop ring 422 in the middle to prevent water leakage from the lifting holes during use.

[0034] The balance beam 1 is connected to the crane hook 6 through the lifting hole 11. The hanging holes 16 at both ends of the balance beam 1 are connected to the U-shaped rings 22 of the sling 2 through the sling pins 21.

The hook gauge 3 is hung on the crane auxiliary hook 5 via the third sling. The culvert 4 is placed between the bottom of the hook gauge 3 and the auxiliary component 33, and the distance is adjusted and fixed with the fixing bolts 32. Tightening the fixing bolts can fix the culvert to the hook gauge, increasing the lifting capacity and making the lifting more stable.

[0040] This invention utilizes a threaded fixing pin that connects to a threaded lifting hole on the culvert, ensuring the pin is securely fixed to the culvert. Simultaneously, a hook ruler is attached to the front end of the culvert using a crane's auxiliary hook, resulting in a more stable and efficient lifting process. Furthermore, the rubber sealing structures at both ends of the culvert, the water-stop rings in the lifting holes, and the reinforced concrete used for the culvert walls significantly improve construction quality.
