TECHNICAL FIELD
[0001] The utility model relates to steel strand technical field, especially a kind of steel strand fixing clamp. BACKGROUND
[0002] In power line, each wire pole or tower for erecting power line usually needs two to eight steel strands of cable-stayed, and one end of the steel strand is fixed to the upper or middle part of the wire pole or tower, and the other end is fixed to the ground, so as to ensure that the wire pole or tower remains vertical and does not tilt when subjected to external force, thereby ensuring the safe operation of the power line. At least one stay fixing tool must be provided in the middle of the cable-stayed steel strand to balance the force around the wire pole or tower. The common stay fixing tool is a UT clamp fixing and a steel wire winding method for limiting and fixing the steel strand. However, this fixing method is complicated and time-consuming in actual operation, which affects the construction speed. Meanwhile, the winding method and the UT clamp are inconvenient to adjust and easy to loosen during adjustment. Therefore, the utility model provides a steel strand fixing clamp which is convenient to adjust and improve the construction speed. SUMMARY
[0003] In view of the above problems of the prior art, the utility model solves the technical problem of providing a steel strand fixing clamp which is convenient to adjust and improve the construction speed.
[0004] To solve the above technical problems, the utility model adopts the following technical scheme:
[0005] A steel strand fixing clamp includes a mounting portion for auxiliary fixing, the mounting portion has a main rope hole and a tail rope hole arranged through in the length direction, the cross-sectional area of the main rope hole and the tail rope hole gradually decreases along the length direction of the mounting portion, and the main rope hole and the tail rope hole are arranged in reverse parallel; a wedge is embedded in the main rope hole and the tail rope hole, so that the main rope and the tail rope respectively arranged in the main rope hole and the tail rope hole are in interference fit with the wedge; the largest end of the main rope hole and the tail rope hole has a step formed by extending radially inward, and the cross-sectional area of the largest end of the wedge matches the step; the step has a threaded hole arranged through, and a fixing bolt is matched in the threaded hole, so that the fixing bolt abuts on the wedge when tightened.
[0006] With the above structure, the wedge is placed in the main rope hole and the tail rope hole respectively, and then the end of the steel strand is passed through the main rope hole to form the main rope, and then passed through the tail rope hole to form the tail rope. The main rope is used to pull the external telegraph pole or electric tower, and the tail rope is used to flow out the length of the rope for easy adjustment and enhance the effect of tension. When the fixing bolt is tightened, the wedge better forms an interference fit with the rope to tighten the telegraph pole. The wedge and the fixing bolt are used to tighten and fix the steel strand. Compared with the traditional winding and binding method, the efficiency of construction can be improved. The wedge in the main rope hole and the tail rope hole will move towards the smaller end of the main rope hole and the tail rope hole under the action of the force of the steel strand, so that the wedge and the steel strand form a more compact interference fit in the main rope hole and the tail rope hole, to ensure that the steel strand is not easy to loosen. In addition, when the length of the wire needs to be adjusted later, the fixing bolt on the tail rope hole can be loosened to move the length of the rope on the tail rope, and then the fixing bolt on the main rope hole is loosened. The length of the rope will be automatically adjusted under the action of the force. If the direction needs to be adjusted, the sequence is reversed. In this way, no matter how to adjust, there is always a wedge to achieve the expected clamping of the main rope or the tail rope, and the adjustment will not be out of control. Therefore, the structure is beneficial to improve the construction efficiency and facilitate the adjustment of the length of the steel strand.
[0007] Further, the smaller end of the cross-sectional area of the wedge is inserted into the main rope hole and the tail rope hole away from the step, so that the wedge and the inner wall of the main rope hole and the tail rope hole form a small hole matched with the diameter of the main rope or the tail rope.
[0008] In this way, the small hole formed by the wedge and the main rope hole and the tail rope hole can fully contact the rope, which is beneficial to increase the friction area and improve the effect of tightening and fixing the rope.
[0009] Further, the side of the wedge facing the small hole is provided with an anti-skid pad, and the anti-skid pad is equidistantly spaced along the length direction of the wedge.
[0010] In this way, the anti-skid pad is beneficial to increase the friction coefficient and better hold the rope.
[0011] Further, the mounting part includes an upper clamp plate and a lower clamp plate; the upper clamp plate and the lower clamp plate are in the shape of W as a whole, T-shaped grooves are arranged on both sides of the width direction of the upper clamp plate and penetrate one side of the length direction of the upper clamp plate; T-shaped pins are correspondingly arranged on both sides of the width direction of the lower clamp plate; and the T-shaped pins are inserted into the corresponding T-shaped grooves.
[0012] In this way, when adjusting, the length of the rope can be adjusted without being too tight; at this time, the upper and lower clamp plates of the mounting part can be slid and detached for adjustment.
[0013] In summary, this utility model has advantages such as easy adjustment of the steel strand length and improved construction efficiency. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the embodiments.
[0019] Example 1: A steel strand fixing clamp, such as Figures 1-3 As shown, the mounting part 1 includes an auxiliary fixing part. The mounting part 1 has a through main rope hole 11 and a tail rope hole 12 along its length. The cross-sectional area of the main rope hole 11 and the tail rope hole 12 gradually decreases along the length of the mounting part 1, and the main rope hole 11 and the tail rope hole 12 are arranged in opposite parallel directions. A wedge 2 is embedded in the main rope hole 11 and the tail rope hole 12 so that the main rope and the tail rope passing through the main rope hole 11 and the tail rope hole 12 are in an interference fit with the wedge. The largest diameter end of the main rope hole 11 and the tail rope hole 12 each has a step 13 extending radially inward and matching the cross-sectional area of the largest end of the wedge 2. The step 13 has a through threaded hole, and a fixing bolt 3 is fitted in the threaded hole so that when the fixing bolt 3 is tightened, it abuts against the wedge 2.
[0020] In implementation, the wedge is placed in the main rope hole and the tail rope hole respectively, and then the steel strand end is passed through the main rope hole to form the main rope, and then passed through the tail rope hole to form the tail rope. The main rope is used to pull the external power pole or tower, and the tail rope is used to flow out the length of the rope for easy adjustment and enhance the effect of tension. When the fixing bolt is tightened, the wedge better forms an interference fit state with the rope to tighten the power pole. The use of wedge and fixing bolt cooperation to tighten and fix the steel strand can improve the efficiency of construction compared with the traditional winding and binding method. The wedge in the main rope hole and the tail rope hole will advance to the smaller end of the main rope hole and the tail rope hole under the action of the force of the steel strand, so that the wedge and the steel strand form a more compact interference fit in the main rope hole and the tail rope hole, to ensure that the steel strand is not easy to loosen. In addition, when the length of the wire needs to be adjusted later, the fixing bolt on the tail rope hole can be loosened first to move the length of the rope on the tail rope, and then the fixing bolt on the main rope hole is loosened. The length of the rope will be automatically adjusted under the action of force. If the direction needs to be adjusted, the sequence is reversed. In this way, no matter how to adjust, there is always a wedge to achieve the expected clamping of the main rope or the tail rope, and the adjustment will not be out of control. Therefore, the use of such a structure is beneficial to improve the construction efficiency and facilitate the adjustment of the length of the steel strand. Finally, the installation part is installed on the connecting rod for insertion into the ground. The UT clamp can also be directly welded or integrally formed on the connecting rod. The main rope hole, tail rope hole and wedge fixing method on the installation part can be used to replace the traditional winding and fixing mode, saving time and effort.
[0021] In addition, in specific implementation, the opposite side of the main rope hole and the tail rope hole on the installation part is not connected, but is separated, which is beneficial to better clamping of the wire.
[0022] As shown in Figure 1 and Figure 2 , in order to make the wedge and the steel strand fully contact to increase friction and area, the smaller end of the cross-sectional area of the wedge 2 is inserted into the main rope hole 11 and the tail rope hole 12 away from the step 13, so that the wedge 2 and the inner wall of the main rope hole 11 and the tail rope hole 12 respectively form a small hole matching the diameter of the main rope or the tail rope. As shown in Figure 1 , further increase the friction, the side of the wedge 2 towards the small hole is provided with a non-slip pad 4, and the non-slip pad 4 is equidistantly spaced along the length direction of the wedge 2.
[0023] In order to solve the problem that the wedge is not easy to loosen in adjustment due to too tight interference fit between the steel strand pull rope and the wedge, and the wedge cannot be adjusted, in the specific implementation, the mounting part 1 comprises an upper clamping plate and a lower clamping plate; the upper clamping plate and the lower clamping plate are in a W shape as a whole, T-shaped grooves are arranged on both sides of the upper clamping plate in the width direction and penetrate one side of the upper clamping plate in the length direction; T-shaped bolts are correspondingly arranged on both sides of the lower clamping plate in the width direction; and the T-shaped bolts are inserted into the corresponding T-shaped grooves. In this way, the upper and lower clamping plates can be taken out and adjusted by sliding. Since the directions of the forces of the main rope and the tail rope are inconsistent, the upper and lower clamping plates are not worried about being automatically taken out when they are inserted and matched with each other. However, the adjustment in the manner of the embodiment 2 cannot adjust the pre-clamping force formed by the main rope or the tail rope as in the adjustment of the embodiment 1, and an artificial pulling force needs to be increased for adjustment.
[0024] The above only describes the preferred embodiments of the present application, and the present application is not limited thereto. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
