AI Technical Summary
In concrete construction, the conduit is easily dropped due to scratches with the reinforcement hoop. The existing rope-slewing method is inefficient and can easily lead to the risk of initial settling of concrete piles.
A simple device for a salvage conduit is designed, including a main body, a suspended rope, a first clamping part, a second clamping part, a clamping port, a buckle plate and a traction rope. The catheter is contacted through the lower opening of the clamp, and the catheter is clamped by the torsion spring of the buckle plate, and the socket and clamp of the buckle plate are controlled by the traction rope.
The device can quickly and safely salvage the fallen conduit, saving a lot of time compared to the rope-tied method, ensuring the smooth progress of concrete pouring and ensuring the quality of piles.

Abstract
Description
Technical Field
[0001] The utility model relates to a fishing device, in particular to a simple device for fishing a conduit. Background Art
[0002] The conduit plays a crucial role in concrete construction. It is mainly used to assist in the concrete pouring work and is the main tool for vertical pouring of concrete and underwater concrete grouting. The conduit (with an indefinite length, which can be 2000 mm or longer) is generally set vertically while pouring concrete and is lifted upward. The lower end of the conduit will remain about 1 - 2 m above the concrete surface. During the construction of bored cast-in-place piles, due to the small diameter of some bored cast-in-place piles (for example, the bored diameter is 800 mm), and the reinforcement stirrups are designed inside the steel cage, during the process of lowering, lifting, installing and disassembling the conduit, the conduit may fall due to rubbing against the reinforcement hoop. When the falling depth of the conduit is too large and it is difficult to retrieve, it will affect the subsequent smooth pouring of concrete. If the conduit is not retrieved, it may cause uneven distribution of concrete in the pile hole, forming voids, seriously affecting the quality of the pile body.
[0003] The commonly used method to retrieve the conduit at present is the rope - sleeving method, that is, tying a knot in the steel wire rope and leading it to the upper part of the fallen conduit with a steel bar, sleeving the pipe orifice with the steel wire rope, and lifting the steel wire rope upward after successful sleeving. The defects of the above - mentioned method are as follows: 1) After the conduit is tilted, the orifice of the conduit is close to the hole wall of the borehole, and the steel wire rope cannot sleeve the conduit, so the fishing cannot be completed; 2) It is difficult to sleeve the pipe orifice with the steel wire rope. It takes at least 4 or 5 hours and at most 8 or 9 hours. Once the fishing time is too long, there will be a risk of broken piles due to the initial setting of concrete. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide a simple device for fishing a conduit, which is convenient and fast to fish out the fallen conduit.
[0005] To solve the above - mentioned technical problem, the technical solution adopted by the utility model is as follows:
[0006] A simple device for fishing a conduit includes a main body. A lifting rope is tied to the upper end of the main body. A first clamping part and a second clamping part are respectively arranged on the left and right sides of the lower end of the main body. A clamping orifice is arranged between the first clamping part and the second clamping part. The bottom end of the first clamping part or the second clamping part is hinged with a clamping plate through a pin shaft and a torsion spring, and the clamping plate presses the conduit.
[0007] A traction rope is fixed to the upper end of the clamping plate, and the traction rope passes through a through - hole on the main body and extends out.
[0008] A rubber layer is fixed to the end face of the clamping plate in contact with the conduit.
[0009] The utility model provides a simple device for fishing a conduit, which has the following technical effects:
[0010] 1) The device contacts the lower opening of the fixture with the upper opening of the conduit. After clamping the conduit using the torsion spring of the buckle plate, it performs lifting and fishing. Usually, the conduit can be taken out after three or four times. Compared with the fishing method using a sleeve rope, it can save a lot of time and the pile forming quality is more guaranteed.
[0011] 2) By adopting an eight-shaped clamping opening, it is convenient to insert into the conduit; by adding a traction rope on the buckle plate, the traction rope is used to pull the buckle plate to form an insertion opening, and after the conduit is inserted, the traction rope is released and the buckle plate clamps the conduit. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the figure: main body 1, first clamping part 2, second clamping part 3, clamping opening 4, buckle plate 5, conduit 6, lifting rope 7, traction rope 8, through hole 9. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] As Figures 1-3 shown, a simple device for fishing a conduit is made of steel and has a certain weight. The device includes a main body 1. A lifting ring is provided at the uppermost end of the main body 1, and the lifting ring can be conveniently connected to the lifting rope 7 to facilitate lowering the device to a certain depth in the drilling hole. In the middle of the main body 1 is a connecting column. On the left and right of the lower end of the main body 1 are respectively provided a first clamping part 2 and a second clamping part 3. A clamping opening 4 is provided between the first clamping part 2 and the second clamping part 3, and the clamping opening 4 is in an eight-shaped, which is convenient for the conduit to extend in. At the bottom end of the second clamping part 3, a buckle plate 5 is hinged through a pin shaft and a torsion spring. When not stressed, the upper end of the buckle plate 5 closely adheres to the inner wall of the first clamping part 2. When the side wall of the conduit is inserted into the clamping opening 4, the buckle plate 5 can press the conduit 6, which is convenient for lifting the conduit 6.
[0018] Preferably, a traction rope 8 is fixed to the upper end of the buckle plate 5, and the traction rope 8 passes through the through hole 9 on the main body 1 and extends out. By pulling the traction rope 8, the interval between the buckle plate 5 and the first clamping part 2 can be widened, which is convenient for inserting the conduit 6. When the traction rope 8 is released, the buckle plate 5 clamps the conduit 6. By providing the traction rope 8, a torsion spring with a relatively large torque can be selected to improve the clamping force on the conduit 6.
[0019] A rubber layer is fixed on the end face of the buckle plate 5 in contact with the conduit 6, thereby increasing the frictional force during clamping.
[0020] Working principle and process:
[0021] 1) During use, first pass the lifting rope 7 (steel wire rope) through the lifting ring and tie it firmly with a buckle to ensure that the device will not fall during the fishing process.
[0022] 2) Subsequently, when the device reaches the position of the conduit, pull up the towing rope 8, and the buckle plate 5 rotates towards the second clamping portion 3; then slowly lower the device to ensure that the side wall of the conduit 6 smoothly passes through the clamping opening 4. Subsequently, slacken the towing rope 8, and the buckle plate 5 presses tightly on the conduit. As Figure 3 shown, finally lift the conduit 6 upwards.
