Description

Technical Field

[0001] This utility model relates to the field of striking components, and more particularly to an automatic striking component for measuring cable tension. Background Technology

[0002] Cable stress measurement is a key technology in engineering, primarily used to assess the stress state of cables in structures such as bridges, stadiums, and high-rise buildings. Accurate cable stress measurement helps ensure the safety and durability of structures and provides a basis for maintenance and management.

[0003] In bridge engineering, microwave radar technology is widely used to measure cable tension. Measurement requires external excitation to induce vibration in the cable, followed by analysis of its frequency characteristics to calculate the tension. Traditional methods primarily rely on manual tapping of the cable with a rubber mallet, which presents the following problems:

[0004] 1. Because shock absorbers are usually installed on the cables, the vibration is rapidly attenuated due to interference from the shock absorbers and because the area that can be tapped is only close to the bridge deck, the tapping position is limited, and the data is inaccurate.

[0005] 2. When performing the hammering, the work requires manual climbing, which poses safety hazards and has poor repeatability.

[0006] Therefore, it is necessary to provide a new automatic tapping component for measuring cable tension to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides an automatic tapping component for measuring cable tension.

[0008] The automatic striking assembly for measuring cable tension provided by this utility model includes two moving devices, which are connected by two telescopic devices arranged opposite to each other. The striking assembly is mounted on both telescopic devices.

[0009] The moving device includes two bent plates, one end of which is hinged together and the other end of which is detachably connected. The two bent plates can be spliced ​​into a square. Mounting frames are fixedly installed on both side walls of the bent plates. Rotating rods are rotatably connected to the mounting frames. Moving wheels are fixedly sleeved on the rotating rods. One end of the rotating rod extends to the outside of the mounting frame. A rotating device is also installed at the bend of the bent plate, which can drive the two rotating rods to rotate.

[0010] Preferably, the rotating device includes a rotating component, a first bevel gear, and a second bevel gear. The rotating component is fixedly installed at the bend of the bent plate. The rotating component can drive one of the rotating rods to rotate. The first bevel gear and the second bevel gear are fixedly connected to the two rotating rods respectively, and the first bevel gear and the second bevel gear mesh with each other.

[0011] Preferably, the rotating component includes a first motor, a third bevel gear, and a fourth bevel gear. The first motor is fixed to the bending plate, and the output end of the first motor is fixedly connected to the third bevel gear. The fourth bevel gear is fixedly connected to one of the rotating rods, and the third bevel gear meshes with the fourth bevel gear.

[0012] Preferably, the telescopic device includes a movable plate, a sleeve, and a fastening bolt. One end of the movable plate is slidably disposed inside the sleeve. The movable plate has multiple through holes. The fastening bolt is threadedly connected to the sleeve, and the end of the fastening bolt can be moved into the through hole of the movable plate.

[0013] Preferably, the striking assembly includes a support rod, a torsion spring, a striking plate, and a pulling member. One end of the support rod is fixed to the outer wall of the sleeve, and the other end of the support rod is fixedly connected to the striking plate. The torsion spring is sleeved on the support rod, and both ends of the torsion spring are fixed to the sleeve and the striking plate, respectively. The pulling member is installed on the outer wall of the sleeve.

[0014] Preferably, the pulling component includes a second motor, a side plate, a movable column, and a rope. The second motor is fixedly installed on the outer wall of the sleeve, and the output end of the second motor is fixedly connected to the side plate. The end of the side plate away from the second motor is rotatably connected to the movable column, and the two ends of the rope are respectively fixed to the movable column and the striking plate.

[0015] Compared with related technologies, the automatic tapping component for measuring cable tension provided by this utility model has the following advantages:

[0016] The first motor drives the third bevel gear to rotate, which in turn causes the fourth bevel gear to rotate. The fourth bevel gear then drives the rotating rod to rotate. Since the first bevel gear meshes with the second bevel gear, the two rotating rods on the bending plate rotate simultaneously, which in turn causes the moving wheels to rotate. The rotation of all four moving wheels enables climbing operations. The moving device expands the striking range and eliminates the need for manual climbing.

[0017] The second motor drives the side plate to rotate, which in turn drives the movable column to rotate. The rope pulls the striking plate to rotate, and the torsion spring deforms to a certain extent. When the movable column does not pull on the rope, the striking plate rotates under the action of the torsion spring, thereby striking the adjacent cable. Attached Figure Description

Figure 3 for Figure 2 A schematic diagram of the structure from another angle is shown; Figure 4 for Figure 1 The diagram shows the structure of the telescopic device and the striking component.

[0025] In the specific implementation process, such as Figures 1-4 As shown, it includes two moving devices, which are connected by two telescopic devices arranged opposite to each other, and both telescopic devices are equipped with a striking component;

[0026] The moving device includes two bent plates 1, one end of which is hinged together and the other end of which is detachably connected by bolts. The two bent plates 1 are respectively equipped with a first upright plate and a second upright plate. When climbing is required, the bolt on the first upright plate is rotated so that one end of the bolt passes through the second upright plate and the nut is tightened on the bolt to complete the connection between the ends of the two bent plates 1. The two bent plates 1 can be spliced ​​into a square. Mounting brackets 2 are fixedly installed on both side walls of the bent plates 1. Rotating rods 3 are rotatably connected to the mounting brackets 2. Moving wheels 4 are fixedly sleeved on the rotating rods 3.

Fixed connection: The end of the side plate 17 away from the second motor 16 is rotatably connected to the movable column 18. The two ends of the rope 19 are fixed to the movable column 18 and the striking plate 15 respectively. The second motor 16 drives the side plate 17 to rotate, which in turn drives the movable column 18 to rotate. The rope 19 pulls the striking plate 15 to rotate, and the torsion spring 14 undergoes a certain degree of deformation. When the movable column 18 does not pull the rope 19, the striking plate 15 rotates under the action of the torsion spring 14, thereby striking the adjacent cable.
