[0040] Refer to the following Figure 1-Figure 8 The invention describes a bridge cable detection device provided by the invention.

[0041] A bridge cable detection device is suitable for tension detection of bridge cables, comprising a frame 100, on which a first sliding block 110 and a second sliding block 120 that can move closer to or farther away from each other are arranged. In this embodiment, the first sliding block 110 is located above the second sliding block 120, and a safety cylinder 200 is arranged between the first sliding block 110 and the second sliding block 120. A cable 130 that needs tension detection is placed in the safety cylinder 200, and two ends of the cable 130 are respectively connected to the first sliding block 110 and the second sliding block 120. When the first sliding block 110 and the second sliding block 120 move away from each other, the cable 130 is pulled, and the cable 130 is gradually broken. The first sliding block 110 and the second sliding block 120 are provided with tension sensors (not shown in the figure), so as to record the tension when the cable 130 is broken, so that the ultimate tension that the cable 130 can withstand can be known, thereby completing the detection of the cable 130.

[0042] A driving component is provided on the frame 100, and the driving component is used to drive the first sliding block 110 and the second sliding block 120 to move closer to or away from each other. A simulation component is also provided on the frame 100, and the simulation component is used to simulate the use environment of the cable 130, for example, simulating the ambient temperature and ambient pressure of the use of the cable 130 in the safety cylinder 200, and the simulation component injects liquid into the safety cylinder 200, and the temperature of the liquid is the ambient temperature when the cable 130 is in use. At the same time, the module component adjusts the pressure in the safety cylinder 200 to simulate the ambient pressure when the cable 130 is in use. Therefore, when the cable 130 is tested, the data of the cable 130 at different temperatures and pressures can be tested by changing the temperature and pressure.

[0043] It is understandable that, on the one hand, the liquid is introduced into the safety cylinder 200 to simulate the temperature, which can isolate the external interference in the air. The liquid can effectively block the influence of wind, noise and temperature fluctuation on the vibration and tension test of the cable 130, and provide a more stable and accurate detection environment. For example, the wind has a significant effect on the vibration of the cable 130, and this interference can be reduced in the liquid, thereby improving the reliability of the detection result. On the other hand, the liquid has a natural shock-absorbing effect, which can absorb the vibration and noise of the cable 130. When the cable 130 is broken, a large amount of kinetic energy will be released, and the liquid can absorb the kinetic energy. At the same time, when the cable 130 is broken, a large noise will be emitted, and even electric sparks will be generated, and the liquid can isolate the noise and avoid the generation of electric sparks.

[0044] Specifically, the simulation component in the embodiment of the present invention includes a first infusion pipeline 210 and a second infusion pipeline 220. The first infusion pipeline 210 is connected to the side wall of the safety cylinder 200, and the second infusion pipeline 220 is connected to the upper end of the safety cylinder 200. Both are connected to the safety cylinder 200. The first infusion pipeline 210 inputs a liquid with temperature into the safety cylinder 200. At the same time, the safety cylinder 200 has a heat preservation effect, so that the temperature of the liquid introduced into the safety cylinder 200 hardly changes. The first infusion pipeline 210 stops conveying when the safety cylinder 200 is filled with liquid, and then the second infusion pipeline 220 starts to convey liquid into the safety cylinder 200. The temperature of the liquid conveyed by the second infusion pipeline 220 is the same as the temperature of the liquid conveyed by the first infusion pipeline 210, but the liquid pressure in the second infusion pipeline 220 is greater than the liquid pressure in the first infusion pipeline 210. The function of conveying liquid by the second infusion pipeline 220 is to increase the pressure inside the safety cylinder 200, thereby simulating the air pressure environment of the cable 130.

[0045] In a further embodiment, there are multiple safety cylinders 200 of the present invention, each of which has a cable 130 placed in it, a rotating disk 260 is provided on the first sliding block 110, and multiple safety cylinders 200 are arranged in a circular array on the rotating disk 260. When the rotating disk 260 rotates, the position of each safety cylinder 200 can be adjusted. When the rotating disk 260 rotates, the tension test of the cables 130 in the safety cylinders 200 on the rotating disk 260 is performed in turn. Therefore, multiple cables 130 are installed at one time, and one round of detection can detect multiple cables 130, which is much more efficient than the traditional method of installing one and testing it once.

[0046] It should be noted that the present invention takes four safety cylinders 200 as an example, but the number is not limited to four and may also be three, five, etc., which is not specifically limited here.

[0047] Specifically, the first infusion pipeline 210 of each safety cylinder 200 is interconnected, and each second infusion pipeline 220 is also interconnected. For the convenience of connection, a support rod 270 is fixedly arranged at the axial position of the rotating disk 260, and the support rod 270 is parallel to the plurality of safety cylinders 200. A first connecting cylinder 230 is fixedly arranged on the support rod 270. The first infusion pipeline 210 of each safety cylinder 200 is connected to the first connecting cylinder 230, and the first connecting cylinder 230 is connected to the first water pipe 231. The heated liquid enters the first connecting cylinder 230 from the first water pipe 231, and then passes through the first connecting cylinder 230. The connecting tube 230 transports the liquid to multiple safety cylinders 200 at the same time; similarly, a second connecting tube 240 is also provided on the support rod 270, and the second connecting tube 240 is connected to the second liquid infusion pipeline 220 of the multiple safety cylinders 200. The second connecting tube 240 is provided with a second water pipe 241, and the second water pipe 241 is also used to transport heated liquid. The difference is that the pressure transported by the second water pipe 241 is greater than the delivery pressure of the first water pipe 231, so that the pressure of the liquid transported in the second water pipe 241 is larger, so that the liquid enters the safety cylinder 200 through the second liquid infusion pipeline 220 to increase the pressure in the safety cylinder 200.

[0048] In a further embodiment, the bottom of each safety cylinder 200 is connected to a water outlet pipe 251, and the multiple water outlet pipes 251 are interconnected. Specifically, a third connecting cylinder 250 is also provided on the support rod 270, and the water outlet pipes 251 of the multiple safety cylinders 200 are all connected to the third connecting cylinder 250, and the third connecting cylinder 250 is also connected to a pumping pipe 252. When all the safety cylinders 200 have undergone a tensile test, the other end of the pumping pipe 252 is connected to a pumping pump to extract the liquid in all the safety cylinders 200.

[0049] It should be noted that, in order to facilitate the fixation of multiple safety cylinders 200, multiple connecting rods 280 are set between each two adjacent safety cylinders 200, so that the multiple safety cylinders 200 can be firmly connected together to prevent the huge kinetic energy generated when the rope 130 in the safety cylinder 200 is broken from destroying the connection of the safety cylinder 200.

[0050] Specifically, the first sliding block 110 and the second sliding block 120 are both provided with clamping jaws 140, and the clamping jaws 140 are distributed up and down, and wedge blocks 202 are provided at both ends of the safety cylinder 200. When the rotating disk 260 moves one of the multiple safety cylinders 200 between the upper and lower clamping jaws 140, the two clamping jaws 140 clamp the two wedge blocks 202 respectively, and the first sliding block 110 and the second sliding block 120 move away from each other under the action of the driving assembly, thereby pulling the cable 130 in the safety cylinder 200. When one cable 130 is detected, the rotating disk 260 moves the other three safety cylinders 200 between the two clamping jaws 140 in turn for detection.

[0051] It should be noted that when multiple safety cylinders 200 are provided, a switch assembly is provided on the second liquid infusion pipeline 220, and a one-way valve 211 is installed in the first liquid infusion pipeline 210. The one-way valve 211 can only allow the liquid in the second liquid infusion pipeline 220 to enter the safety cylinder 200, and the liquid in the safety cylinder 200 cannot flow back to the first liquid infusion pipeline 210. The switch assembly is used to control the connection or blocking of the second liquid infusion pipeline 220 and the safety cylinder 200. If the switch assembly is not provided, the high-pressure liquid in the second water pipe 241 enters each safety cylinder 200 through the second liquid infusion pipeline 220 after being distributed by the second connecting cylinder 240, so that all safety cylinders 200 are always in high pressure, that is, when one safety cylinder 200 is detected, other safety cylinders 200 are also in a high pressure state when waiting for detection. If the safety cylinder 200 is always in a high pressure state, it will affect the sealing performance of the safety cylinder 200, that is, the sealing performance of the safety cylinder 200 will gradually decrease. A switch assembly is provided and configured such that: when the cable 130 starts to be pulled and is pulled to a preset position, the second infusion pipeline 220 is connected, and when the cable 130 is not pulled, the second infusion pipeline 220 is not connected to the safety cylinder 200, thereby ensuring that when the cable 130 in the safety cylinder 200 does not start to be detected, the internal air pressure of the safety cylinder 200 is in a normal state, preventing the safety cylinder 200 from being in a high-pressure state all the time.

[0052] Specifically, the switch assembly of the present invention includes a connecting block 201 and a supporting sleeve 203, the supporting sleeve 203 is connected to the upper end of the safety sleeve 200, an annular groove 205 is provided on the inner side wall of the supporting sleeve 203, and the outer side wall is connected to the second infusion pipeline 220, and the opening of the second infusion pipeline 220 is located in the annular groove 205, the connecting block 201 is slidingly sealed and arranged on the inner wall of the supporting sleeve 203, a through groove 206 is provided on the side wall of the connecting block 201, one opening of the through groove 206 is located on the side wall of the connecting block 201, and the initial position of the through groove 206 is lower than the position of the annular groove 205 of the supporting sleeve 203; the other opening of the through groove 206 is located at the bottom of the connecting block 201, and for the convenience of connection, the lower part of the connecting block 201 is fixedly connected One end of the cable 130, and the upper end of the connecting block 201 is fixedly connected to the wedge block 202. When the first sliding block 110 and the second sliding block 120 move away from each other to pull the cable 130, the connecting block 201 moves upward axially relative to the support sleeve 203, so that the opening of the through groove 206 on the side wall of the connecting block 201 can gradually approach the annular groove 205 on the inner wall of the support sleeve 203. When the two are in contact, the high-pressure liquid in the second infusion pipeline 220 enters the safety cylinder 200 through the annular groove 205 and the through groove 206 to increase the pressure of the safety cylinder 200, while the connecting blocks 201 on other safety cylinders 200 do not move axially relative to the support sleeve 203, so the high-pressure gas in the second infusion pipeline 220 cannot enter.

[0053] To facilitate the connection of the cable 130, a connecting block 201 and a supporting sleeve 203 are also provided at the bottom of the safety cylinder 200. However, the connecting block 201 at the bottom is fixedly set at the bottom of the safety cylinder 200 and cannot move axially relative to it. A connecting shaft 204 is provided on the two connecting blocks 201. The two ends of the cable 130 to be tested are distributed around the connecting shaft 204 and fixed to the connecting shaft 204 by a clamp or other locking parts.

[0054] It should be noted that the switch assembly of the present invention is not limited to the above structure, but can also be the following structure:

[0055] The second liquid infusion pipeline 220 is always connected to the side wall of the safety cylinder 200. A solenoid valve is arranged in the second liquid infusion pipeline 220. The solenoid valve is used to control the connection state of the second liquid infusion pipeline 220. When the safety cylinder 200 is ready for a tension test, the solenoid valve opens the second liquid infusion pipeline 220, and the high-pressure liquid enters the safety cylinder 200. When other safety cylinders 200 do not start tension tests, the solenoid valve closes their second liquid infusion pipelines 220. Of course, other structures are also possible, which are not specifically limited here.

[0056] In a further embodiment, the driving assembly of the present invention includes a driving motor (not shown in the figure) and a spiral shaft 300. The driving motor is fixedly arranged on the frame 100, and the spiral shaft 300 is rotatably connected to the frame 100. The spiral groove on the surface of the spiral shaft 300 has two parts, and the rotation directions of the two parts of the spiral groove are opposite, and the dividing point is at the midpoint of the length of the spiral shaft 300. The first sliding block 110 and the second sliding block 120 are respectively spirally matched with the two parts of the spiral groove of the spiral shaft 300. The driving motor can drive the spiral shaft 300 to rotate. When the spiral shaft 300 rotates in one direction, the first sliding block 110 and the second sliding block 120 can realize the function of moving away from or approaching each other. When they move away from each other, they can detect the cable 130, and when they move close to each other, they reset.

[0057] Specifically, a guide column 310 is further provided in this embodiment, one end of which is fixedly disposed on the frame 100 and the axis of the guide column 310 is parallel to the axis of the screw shaft 300, a guide groove 111 is provided on the first sliding block 110, and the other end of the guide column 310 is inserted into the guide groove 111, thereby playing a guiding role, so that the first sliding block 110 and the second sliding block 120 move smoothly in the vertical direction.

[0058] It should be noted that there are two of the above-mentioned spiral shafts 300 and guide columns 310, and the positions of the two spiral shafts 300 and the two guide columns 310 are symmetrical about the center of gravity of the first sliding block 110. Since there are only two spiral shafts 300 and two guide columns 310 must be taken into consideration at the same time, the two spiral shafts 300 can be set on a straight line passing through the center of gravity of the first sliding block 110. In addition, the clamping jaws 140 of the first sliding block 110 are located at its center position, so that when the two spiral shafts 300 drive the first sliding block 110 to move to pull the cable 130, the force on the first sliding block 110 will be more uniform.

[0059] Of course, the two screw shafts 300 may be symmetrically arranged, but the two guide posts 310 must be located on the same vertical plane where the two screw shafts 300 are located, so that the first sliding block 110 can be evenly stressed.

[0060] The specific working process of a bridge cable detection device provided by the present invention is described in combination with the above embodiments:

[0061] Install:

[0062] A plurality of cables 130 are respectively installed in a plurality of safety cylinders 200, and the water extraction pipe 252 on the third connecting cylinder 250 is closed, and the heated liquid is input from the first water pipe 231 into the first connecting cylinder 230. The liquid moves to the plurality of first liquid infusion pipes 210 in the first connecting cylinder 230 at the same time, and the liquid enters each safety cylinder 200 through the one-way valve 211 of the first liquid infusion pipe 210. When the liquid in each safety cylinder 200 is full, the delivery of the first water pipe 231 is stopped, and the second water pipe 241 starts to deliver liquid of the same temperature, but the liquid pressure is relatively large, and the liquid enters the second connecting cylinder 240 through the second water pipe 241. The liquid in the second connecting cylinder 240 cannot pass through the second liquid infusion pipe 220 because at this time the through groove 206 on the side wall of the connecting block 201 is not connected to the annular groove 205 on the inner wall of the supporting sleeve 203.

[0063] Start detection:

[0064] When the rotating disk 260 moves one of the plurality of safety cylinders 200 between the clamping jaws 140 of the first sliding block 110 and the second sliding block 120, the driving motor starts to rotate and starts to drive the screw shaft 300 to rotate. The screw shaft 300 rotates to drive the first sliding block 110 and the second sliding block 120 to move closer to each other. After the clamping jaws 140 clamp the wedge block 202, the screw shaft 300 rotates in the opposite direction to drive the first sliding block 110 and the second sliding block 120 to move away from each other to pull the wedge block 202. The wedge block 202 is fixedly connected to the connecting block 201, so that the safety cylinder 200 is 00, the connecting block 201 at the upper end moves axially with the supporting sleeve 203, and the connecting block 201 moves upward relative to the supporting sleeve 203, thereby connecting the through groove 206 on the side wall of the connecting block 201 with the annular groove 205 on the inner wall of the supporting sleeve 203, and the liquid in the second infusion pipeline 220 enters the safety cylinder 200 through the annular groove 205 and the through groove 206 to increase the pressure in the safety cylinder 200, and the first sliding block 110 and the second sliding block 120 continue to move away from each other to break the cable 130, thereby detecting the ultimate tension of the cable 130.

[0065] The connecting blocks 201 on other safety cylinders 200 that have not started testing do not move relatively, so the second infusion pipes 220 connected thereto are not connected to the safety cylinders 200, so the pressures in these safety cylinders 200 are in a normal state. When the cable 130 in the previous safety cylinder 200 is tested, the rotating disk 260 rotates to move another safety cylinder 200 between the two clamping jaws 140 to start testing, and this cycle continues until all the cables 130 are tested and replaced with new cables 130.

[0066] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
