Description

Technical Field

[0001] The utility model relates to the technical field of anchor cable prestress detection, in particular to an intelligent induction detection device for anchor cable prestress. Background Art

[0002] Anchor cables refer to the process of anchoring the main cables in the side holes of a suspension bridge. The main cables are divided into many steel bundles and anchored in anchor ingots respectively. These steel bundles are called anchor cables. Prestressing is to improve the service performance of the structure. The compressive stress is pre-applied to the structure during construction. During the service of the structure, the pre-stressing stress can fully or partially offset the tensile stress caused by the load and avoid structural damage. In order to ensure the stability and safety of anchor cable prestressed structures (such as foundation pits, bridges, tunnels, etc.) during use, it is necessary to test the anchor cable prestressing. Existing anchor cable prestressing detection usually has problems such as difficult detection and inaccurate measurement. Therefore, an intelligent sensing detection device for anchor cable prestressing is needed to solve the above problems.

[0003] The existing technology has the following deficiencies:

[0004] 1. When using the existing intelligent induction detection device for prestressed anchor cables, it is necessary to connect the connecting pipeline on the output device to the connecting end of the tensioning device. The connecting pipeline and the connecting end are usually simply snap-fitted. During use, the connecting pipeline is easily detached from the connecting end, thereby affecting the stability of the tensioning device.

[0005] 2. When carrying the tensioning device of the existing anchor cable prestressed intelligent sensing detection device, the user usually holds the handle to carry the tensioning device. Since the tensioning device itself is heavy, the handle can easily cause strangulation of the user's hand, affecting the user's hand comfort. The user's hand comfort when holding the tensioning device can be further improved. Utility Model Content

[0027] In this embodiment, the anchor rod of the anchor cable 3 passes through the tensioning device 1, the installation end of the connecting pipeline 7 is inserted into the connecting end head 6, and the swivel 801 is rotatably installed on the connecting end head 6;

[0028] Specifically, the swivel 801 can conveniently drive the rotation of the fixing member 803;

[0029] In this embodiment, the top and bottom of the swivel 801 are fixed with fixing members 803, and the fixing members 803 are in an "L" shape as a whole;

[0030] Specifically, the fixing member 803 can limit and fix the stopper 802;

[0031] In this embodiment, a stopper 802 is fixedly installed on the top and bottom of the connecting pipeline 7. The stopper 802 is fan-shaped as a whole, and one side of the stopper 802 is in contact with one side of the swivel 801.

[0032] Specifically, the stopper 802 can facilitate the connection between the fixing member 803 and the connecting pipeline 7;

[0033] In this embodiment, the inner sides of the two sets of fixing members 803 are respectively in contact with the two sets of stoppers 802. Magnet blocks 804 are embedded in the contacting sides of the two sets of stoppers 802 and the corresponding positions of the fixing members 803. The magnet blocks 804 on the stoppers 802 and the fixing members 803 are magnetically attracted to each other.

[0034] Specifically, the magnet block 804 can facilitate the fixation of the fixing member 803 and the stopper 802 when they are attached;

[0035] In this embodiment, the elastic block 9 is fixedly mounted on the top of the inner wall of the handle 4, and a plurality of mini airbags 11 are fixedly mounted in the mounting opening 10, and the mini airbags 11 are elliptical in shape as a whole;

[0036] Specifically, the elastic block 9 itself has a certain elasticity and is made of a relatively soft material, which can preliminarily improve the comfort of the user's hand;

[0037] In this embodiment, the anti-slip pad 13 is fixedly mounted on the top of the handle 4. A plurality of anti-slip strips 12 are fixedly mounted on the bottom of the elastic block 9 and the top of the anti-slip pad 13. The anti-slip strips 12 are semi-cylindrical in shape.

[0038] Specifically, the anti-slip strip 12 can improve the anti-slip properties of the elastic block 9 and the anti-slip pad 13 .

[0039] The working principle and use process of the present invention are as follows: the anchor rod of the anchor cable 3 passes through the detection port of the tensioning device 1, the swivel 801 is rotated so that the two sets of fixing parts 803 are located on both sides of the swivel 801, the installation end of the connecting pipeline 7 is inserted into the connecting end head 6, and the swivel 801 is rotated so that the two sets of fixing parts 803 are respectively located at the top and bottom directions of the swivel 801. At this time, the two sets of fixing parts 803 are respectively attached to the two sets of stoppers 802. Due to the magnetic attraction between the fixing parts 803 and the magnet blocks 804 on the stoppers 802, the stoppers 802 and the fixing parts 803 are not easy to rotate and displace, and the fixing parts 803 can prevent the stoppers 802 from moving away. Move in the direction away from the swivel 801, thereby preventing the connecting pipeline 7 from being separated from the connecting end 6. Reverse the above operation to separate the connecting pipeline 7 from the connecting end 6. At this time, the other end of the connecting end 6 is connected to the output device of the tensioning device 1. The tensioning device 1 uses a piezoelectric ceramic sensor to detect the stress change of the anchor cable 3 (piezoelectric ceramics have a unique coupling performance of electrical displacement and mechanical displacement, and the induced potential is measured to determine the stress of mechanical deformation), which can achieve rapid non-destructive testing. The data can be fed back to the supporting CNC terminal in real time for intelligent analysis, thereby improving the detection ratio, avoiding damage to the anchor cable 3 caused by repeated tensioning, and greatly improving the detection ratio;

[0040] When the tensioning device 1 is carried by holding the handle 4, since the elastic block 9 itself has a certain elasticity and is made of a soft material, the comfort of the contact part between the handle 4 and the user's hand can be initially improved. The mini airbag 11 can improve the elastic effect of the elastic block 9 and its own material is soft. The anti-slip strip 12 can improve the anti-slip properties of the elastic block 9 and the anti-slip pad 13, which can prevent the handle 4 from sliding randomly when the user holds the tensioning device 1, thereby further improving the comfort of the user's hand when holding the tensioning device 1.
