Description

TECHNICAL FIELD

[0001] The utility model relates to water conservancy engineering technical field especially a kind of bundle of cable and cable of beam winch. BACKGROUND

[0002] Prestressed pier anchorage is a common structure reinforcement technique, mainly used to improve the stability and load-carrying capacity of buildings such as dams and bridges. Its basic principle is to apply a certain tension to the anchor cable (usually made of high-strength steel) in advance, so that it can effectively resist external loads and deformation after construction is completed. In large-scale water conservancy construction, prestressed pier anchorage is often used to improve the stability and load-carrying capacity of buildings such as dams and bridges.

[0003] For example, Dongzhuang Water Conservancy Complex, the main dam is a concrete double-curvature arch dam with high dam body and complex structure. In order to enhance the stability and load-carrying capacity of the dam, the project adopts prestressed pier anchorage design, including U-shaped main anchor cable and cross secondary anchor cable. The design tonnage of the U-shaped main anchor cable is as high as 4000KN, which is composed of 26 7Ф5 prestressed steel strands with a length of 61m to 79m.

[0004] In actual construction process, due to the narrow platform of the orifice pier of desilting bottom outlet and desilting flood discharge deep hole, it is impossible to set up a material stacking rack for unloading and cable weaving operation. It is necessary to unload in the field outside the dam, and then wind the single steel strand on the beam winch, that is, wind multiple steel strands on the same winch, and then hoist it to the pier platform by cable machine for cable weaving and threading. When winding multiple steel strands on the same winch, it is easy to cause confusion and knotting of steel strands, which prolongs the construction period of cable weaving and threading, and is very inconvenient.

[0005] Therefore, in order to improve the efficiency of cable weaving and threading, the utility model provides a beam winch for cable weaving and threading. UTILITY MODEL CONTENTS

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0024] This utility model discloses a bundled winch for cable braiding and threading. In situations where the gate pier platform 104 is too small to allow for material unloading and cable braiding, the material must be unloaded at an off-site location on the dam face. The bundled winch then winds up individual steel strands 101 and hoists them to the gate pier platform 104 for cable braiding and threading, thus solving the problem of not being able to directly braid and thread cables on the gate pier platform 104.

[0025] Reference Figure 1 , Figure 3 and Figure 4 As shown, a cable-bundling winch includes two circular reels 1, a connecting shaft 8 between the reels 1, six connecting frames 9 distributed on the outside of the connecting shaft 8, 25 partition frames 2 connected to the outside of the connecting frames 9, 26 U-shaped clips 3 on one of the six connecting frames 9, coaxial rotating shafts 4 welded to the outside of the two reels 1, bearing seats 5 sleeved on the rotating shafts 4, and bases 7 welded to the bottom of the bearing seats 5. The number of U-shaped clips 3 is one more than the number of partition frames 2. Figure 5 As shown, a U-shaped clip 3 is provided between each of the two separating frames 2, and a U-shaped clip 3 is provided between the separating frame 2 and the circular reel 1.

[0026] The circular reel 1 is made from recycled cable reels or welded steel pipes. The six connecting frames 9 are made of A50 steel pipes. The main function of the connecting frames 9 is to facilitate the fixing of the separating frames 2 and U-shaped clips 3. The separating frames 2 are welded from A8 steel bars. The rotating shaft 4 is made of A50 steel rods, and the base 7 is made of welded steel. The base 7 is connected to the rotating shaft 4 via bearing seats 5. The rotating shaft 4 and bearing seats 5 are connected via bearings 51. The rotating shaft 4 can rotate relative to the base 7, and the split winch can rotate above the base 7.

[0027] As a preferred option, such as Figure 3 As shown, the connecting frame 9 is arranged in a ring at equal intervals around the connecting shaft 8, with the connecting shaft 8 as the axis. The two ends of the connecting frame 9 are connected to the two circular reels 1 respectively.

[0028] As a preferred option, such as Figure 1 As shown, 25 partition frames 2 are arranged equidistantly along the axis of the connecting frame 9, and the spacing is 2-3 times larger than the diameter of a single steel strand 101.

[0029] As a preferred option, such as Figure 3 As shown, a partition frame 2 includes three partition rods 21 and a connecting ring 22. One end of the three partition rods 21 is connected to different connecting frames 9 respectively. Specifically, each partition rod 21 is spaced apart by a connecting frame 9, and the other end is connected to the connecting ring 22. The gap between two partition frames 2 and the gap between the partition frame 2 and the circular reel 1 can accommodate steel strands 101.

[0030] As a preferred option, such as Figure 1 As shown, one end of the rotating shaft 4 passes through the bearing seat 5, and the part passing through the bearing seat 5 is connected to the output shaft of the reducer 6 via a belt. The reducer 6 is fixed on the side bracket 71 located on the outside of the base 7, and the bottom of the side bracket 71 is provided with a diagonal brace.

[0031] By connecting the frame 9 and separating the frame 2, the space between the two circular reels 1 is divided into multiple cylindrical small spaces. Only a single steel strand 101 is wound in each space, avoiding the tangling of multiple steel strands 101. U-shaped clips 3 are installed on the connecting frame 9. After the single steel strand 101 is cut, the front end of the steel strand 101 is first fixed with the U-shaped clip 3. The U-shaped clip 3 is then locked with a nut before winding. After winding, the end of the steel strand 101 is fixed to the separating frame 2 with a thin wire to prevent the steel strand 101 from popping out. One strand is cut and one is wound at a time. Figure 6 As shown, after the winding is completed, the entire cable is hoisted onto the gate pier platform 104 using a cable crane. The steel strands 101 on the split winch are released and installed on the isolation bracket. The cable is then braided using the guide rod 103. The guide rod 103 is located on the outside of the support beam 102. To prevent the steel strands 101 from causing the split winch to rotate too fast under its own weight during the cable braiding process, which could pose a safety risk, a reducer 6 is added to the rotating shaft 4 to ensure that the split winch rotates at a uniform speed.

[0032] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited thereto. The substitution can be the substitution of part of the structure, device, method step, or the complete technical solution. According to the technical solution of the present application and the inventive concept, equivalent substitution or change should be covered in the protection scope of the present application.
