Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope fastening and installation, in particular to a connecting tensioner and a guardrail thereof. Background Art

[0002] At present, various metal guard nets, barrier nets, etc. formed by connecting steel wire ropes between the columns on both sides are widely used because of their convenient installation and good impact resistance to play a corresponding protective role. For such metal guard nets and barrier nets, during installation and construction, corresponding connection tensioners need to be used to connect and tighten the steel wire ropes and apply a certain pre-tensioning force. Some existing connection tensioners usually include a ferrule and a tubular component. The ferrule is configured to be attached to the steel wire rope and inserted into the hole in the column. The tubular component has an axial center channel for receiving the steel wire rope passing therethrough. The tubular component includes a threaded outer The surface of the invention comprises a structure in which the thread is configured to engage the hole of the column and to push the tubular component into the hole of the column in response to the rotation of the tubular component, wherein the ferrule is driven by the tubular component into the hole in the column in response to the rotation of the tubular component in the hole. In the connecting tensioner, the ferrule is swaged to the wire rope. Since relative slippage is likely to occur between the ferrule and the wire rope during the swaging process, the final swaging position of the ferrule is difficult to control and the operation is difficult. At the same time, the wire rope needs to pass through the tubular component and the ferrule, and the excess wire rope at the front end needs to be removed after the swaging is completed, which directly causes waste of the wire rope and indirectly increases the cost.

[0024] Preferably, the cable 4 is a steel wire rope or a cable made of other materials.

[0025] By providing the forged connection hole 211 opened to one end of the forged connection part 21 of the connecting rod 2, an entrance is formed on the forged connection part 21 at the end away from the slotted component 1, so that the cable 4 can be smoothly inserted. Since the forged connection hole 211 is adapted to the cable 4 and the internal space in the forged connection hole 211 is limited, the relative slip between the cable 4 and the connecting rod 2 can be effectively restricted, and the operation is simpler. In addition, since the cable 4 does not need to pass through the overall structure of the connecting rod 2 and the slotted component 1, one end of the cable 4 only needs to be inserted into the forged connection hole 211 and fixedly connected by forging, so that no excess part is generated and cut off, which effectively avoids the waste of the cable 4, thereby saving the cable 4 and saving costs. By setting the snap-fit ​​connection part 22, it is convenient to connect the connecting rod 2 with the slotted component 1, so that the two are connected as a whole. By setting the threaded connection part 11 on the slotted component 1, it is used to be threadedly connected and fixed with the mounting hole 31 on the column 3. Correspondingly, the mounting hole 31 is provided with an internal thread that matches the external thread 111. At the same time, with the setting of the rotating operating part 12, it is convenient to use a corresponding tool to operate to drive the threaded connection part 11 to rotate, so that the slotted component 1 moves along its axial direction relative to the column 3 in the mounting hole 31, and drives the connecting rod 2 to move together, so as to realize the tightening of the cable 4, and the columnar connection tensioner can be completely hidden in the mounting hole 31 of the column 3 to ensure the overall appearance.

[0026] Two symmetrical planar cut surfaces 127 are disposed on the outer circumference of the rotating operation portion 12 , so that it is convenient to use corresponding tools to clamp the two planar cut surfaces 127 and drive the rotating operation portion 12 to rotate.

One end of the solid cylinder 222 is fixedly connected to the solid disc 221, and the other end of the solid cylinder 222 is fixedly connected to the forging connection portion 21. The outer diameter of the solid disc 221 is larger than the outer diameter of the solid cylinder 222, and the outer diameter of the forging connection portion 21 is larger than the outer diameter of the solid cylinder 222. One end of the threaded connection portion 11 is provided with The through groove 112 is used to accommodate the solid disc 221, and the rotating operating part 12 is provided with an open groove 121 which is communicated with the through groove 112 and is used to accommodate the solid cylinder 222. The solid disc 221 and the through groove 112 are loosely matched, and the solid cylinder 222 and the open groove 121 are loosely matched. When the solid disc 221 is inserted into the through groove 112 and the solid cylinder 222 is inserted into the open groove 121, the connection between the connecting rod 2 and the slotted component 1 can be achieved, and the stability of the connection between the two can be effectively ensured.

[0028] The method for using the connecting tensioner and the guardrail described in the utility model is as follows:

[0029] Insert one end of the cable 4 into the forging connection hole 211 of the connecting rod 2, and achieve a fixed connection between the cable 4 and the connecting rod 2 by forging;

[0030] The solid disc 221 and the solid cylinder 222 of the connecting rod 2 are respectively inserted into the through groove 112 and the open groove 121 of the slotted component 1, thereby achieving a stable connection between the connecting rod 2 and the slotted component 1;

[0031] The slotted component 1 is initially screwed into the mounting hole 31 of the column 3 through the threaded connection portion 11, and then the corresponding tool is used to operate and drive the rotating operation portion 12, thereby driving the threaded connection portion 11 to rotate, so that the slotted component 1 moves axially relative to the column 3 in the mounting hole 31, and drives the connecting rod 2 to move together, thereby pulling the cable 4 and continuously pulling it into the mounting hole 31 of the column 3, thereby tightening the cable 4. In this process, as the slotted component 1 rotates, the cable 4 remains rotating and stationary.
