Description

Technical Field

[0001] The present invention relates to the technical field of tension measurement of tensioning members, and more particularly to a signal acquisition device and method for measuring tension values. Background Art

[0002] Currently, most load cells used to measure the tension of tensioned components (such as cables and rods) directly measure the pressure on the axis. Current operating methods include: 1. Hydraulic sensors, which are welded to form a sealed chamber that is then filled with hydraulic oil. When the sealed chamber is compressed or stretched on the axis, the internal oil pressure changes, measuring the tension. 2. Resistive sensors, which use a sensing plate fixed to the outer circle of an elastomer. When the elastomer is compressed or stretched on the axis, it deforms. The sensing plate feeds the data back to a computing system, which then measures the tension. 3. Fiber Bragg grating (FBG) sensors, which use a slotted and welded fiber Bragg grating (FBG) to the outer circle of an elastomer. When the elastomer is compressed or stretched, it deforms. The FBG transmits the data to a computing system, which then measures the tension.

[0003] The shortcomings of the current process are: 1. Hydraulic sensors are difficult to weld in confined spaces, difficult to process, and difficult to remove air when filling hydraulic oil; 2. The elastomer structure of the resistive sensor is large and heavy, which limits the working conditions; 3. The fiber grating sensor has a large elastic structure, and the groove used for welding and fixing the fiber grating is difficult to process. In addition, the fiber grating is a brittle material, requiring the straightness and smoothness of the groove to be high, and the production cost is high. Summary of the Invention

[0031] Step 26. Tighten the compression nut and retract the jack cylinder to convert the tension of the tensioning member to the first hoop body and the second hoop body.

[0032] Beneficial effects

[0033] Compared with the prior art, the present invention has the following advantages:

[0034] 1. The present invention installs an elastic member on the locking bolts of the first hoop body and the second hoop body, and installs a sensor on the elastic member, thereby measuring the horizontal force component instead of directly measuring the vertical force value, thereby reducing the difficulty of measurement and the structural size of the elastic member. If the sensor is a strain gauge type (resistance sensor) attached to the elastic member, the number of strain gauges can be reduced due to the small structure of the elastic member. If the sensor is a fiber optic Bragg grating welded on the elastic member, the small size of the elastic member is more conducive to ensuring the welding quality and reducing the difficulty of processing the fixing groove of the fiber optic Bragg grating. If the sensor is a hydraulic sensor installed on the elastic member, the small size of the elastic member requires a small size of the hydraulic sensor, which can reduce the difficulty of processing the hydraulic sensor.

[0035] 2. The present invention generates a large horizontal force when measuring a large-tonnage vertical force. At this time, the horizontal force on the elastic member is reduced by increasing the friction between the friction plate and the first hoop body and the second hoop body, thereby reducing the structural size of the elastic member.

DETAILED DESCRIPTION

[0049] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0050] See Figures 1 to 12A signal acquisition device for measuring tension value includes a first hoop body 2 and a second hoop body 3 for tightening a tensioning member 1. The first hoop body 2 and the second hoop body 3 are respectively located on both sides of the tensioning member 1. At least one set of locking measuring mechanisms is provided between the first hoop body 2 and the second hoop body 3. The locking measuring mechanism includes a locking bolt 4, a locking nut 5, and an elastic member 6. The locking bolt 4 passes through the first hoop body 2 and the second hoop body 3 in sequence. The elastic member 6 is sleeved on the outer wall of the locking bolt 4. The locking nut 5 is tightened on one end of the locking bolt 4 and puts the elastic member 6 in an extruded state. The elastic member 6 is provided with a detection sensor 7 for detecting deformation of the elastic member 6.

[0051] The detection sensor 7 is any one of a hydraulic sensor, a resistive sensor, and a fiber grating sensor.

[0052] The deformation of the tensioning member 1 due to the force causes the deformation of the first hoop body 2 and the second hoop body 3, which further causes the deformation of the elastic member 6 on the locking bolt 4. The traditional direct measurement of the vertical force value is replaced by the measurement of the horizontal force component, which reduces the difficulty of measurement and reduces the structural size of the elastic member. If the sensor is a strain gauge attached to the elastic member (resistance sensor), the number of strain gauges can be reduced due to the small structure of the elastic member. If the sensor is a fiber optic Bragg grating welded on the elastic member, the small size of the elastic member is more conducive to ensuring the welding quality and reducing the difficulty of processing the fixing groove of the fiber optic Bragg grating. If the sensor is a hydraulic sensor installed on the elastic member, the small size of the elastic member requires a small size of the hydraulic sensor, which can reduce the difficulty of processing the hydraulic sensor.

[0053] The first hoop body 2 and the second hoop body 3 have the same structure; locking holes 8 are provided on both sides of the first hoop body 2 and the second hoop body 3, and the locking bolts 4 pass through the locking holes 8 of the first hoop body 2 and the second hoop body 3 in sequence.

[0054] At least one safety mechanism is provided between the first hoop body 2 and the second hoop body 3. The safety mechanism includes a safety bolt 9 and a safety nut 10. The safety bolt 9 passes through the first hoop body 2 and the second hoop body 3 in sequence. The safety nut 10 is screwed into one end of the safety bolt 9 but is not tightened. The safety mechanism has two functions: one is to prevent the first hoop body 2 and the second hoop body 3 from separating when the elastic member 6 is replaced (for the purpose of replacing the detection sensor 7); the other is to prevent the elastic member 6 from being crushed by excessive horizontal force of the tensioning member 1.

[0055] Preferably, there are two groups of locking and measuring mechanisms, which are respectively arranged at the two ends of the first hoop body 2 and the second hoop body 3 , and there are two groups of safety mechanisms, which are arranged between the two groups of locking and measuring mechanisms.

[0056] Furthermore, a friction-enhancing plate 11 is provided at one end of the first hoop body 2 and the second hoop body 3, and a friction surface with a set friction coefficient is provided between the first hoop body 2, the second hoop body 3 and the friction-enhancing plate 11. When measuring large-tonnage vertical forces, the horizontal force generated is large. For example, when the tension of the tension member 1 is several thousand tons, the horizontal component force can reach several hundred tons. If the force of several hundred tons is measured directly through the elastic member 6 and the detection sensor 7, the elastic member 6 must be made very large to prevent it from being crushed. In this case, the friction between the friction-enhancing plate and the first hoop body and the second hoop body reduces the horizontal force on the elastic member, thereby reducing the structural size of the elastic member. That is, the horizontal component force F1 = the force F2 on the elastic member + the friction force F3, and the friction coefficient μ = F3 / N, where N is the tension of the tension member 1.

[0057] Example 1

[0058] like Figures 1 to 3 As shown, the first hoop body 2, the second hoop body 3 and the tensioning member 1 are connected by threads. That is, the tensioning member 1 is provided with external threads, and the first hoop body 2 and the second hoop body 3 are provided with internal threads that match the external threads.

[0059] like Figure 8 As shown, a method for measuring tension value of a signal acquisition device according to the first embodiment includes the following steps:

[0060] Step 11. Preliminary preparation: Install the support leg 15 and the friction-increasing plate 11 on the end face of the anchor plate 16, set the intermediate plate 17 inside the support leg 15, install the anchor nut 18 on the intermediate plate 17, install the jack 19 on the top of the support leg 15, install the tensioning nut 20 on the end face of the jack 19, pass the tensioning rod 21 through the tensioning nut 20, jack 19, support leg 15, anchor nut 18, and intermediate plate 17 in sequence, pass the tensioning member 1 through the anchor plate 16 and friction-increasing plate 11 in sequence, and connect it to the tensioning rod 21. The tensioning rod 21 is threadedly connected to the tensioning nut 20, anchor nut 18, and tensioning member 1.

[0061] Step 12. Loosen the anchor nut 18;

[0062] Step 13. Control the jack 19 to extend the cylinder, the tensioning nut 20 and the tensioning rod 21 follow, the tensioning member 1 is pulled out by force, and the anchor nut 18 is separated from the middle plate 17;

[0063] Step 14. After the jack 19 stops, tighten the anchor nut 18 to transfer the tension to the middle plate 17. The jack 19 retracts, and the tension nut 20 moves and is tightened;

[0064] Step 15. Repeat steps 12 to 14 until the tensioning member 1 is tensioned to the set tensioning force value;

[0065] Step 16. Snap the first hoop body 2 and the second hoop body 3 into the external thread of the hoop tension member 1.

Insert the locking bolt 4 through the first hoop body 2 and the second hoop body 3 in sequence. Attach the elastic member 6 to the locking bolt 4. Screw the locking nut 5 into one end of the locking bolt 4 to compress the elastic member 6. Pre-tighten the locking nut 5 to the set pre-tightening force value.

[0066] Step 17. The jack 19 retracts the cylinder, loosens the anchor nut 18, and converts the tension of the tension member 1 to the first hoop body 2 and the second hoop body 3. The first hoop body 2 and the second hoop body 3 are deformed by the force, thereby driving the elastic member 6 to deform. The detection sensor 7 of the elastic member 6 feeds back the detection data of the deformation of the elastic member 6 to the data acquisition module and the computer processing system 22. After being processed by the preset software, the current tension value of the tension member 1 is displayed.

[0068] like Figures 9 to 11 As shown, the ends of the first and second hoop bodies 2 and 3, away from the friction-enhancing plate 11, are provided with an extrusion groove 12 with a large opening and a small bottom. An extrusion plate 13 is disposed within the extrusion groove 12. A compression nut 14 is provided on one side of the extrusion plate 13 for threaded connection with the tensioning member 1 and for pressing the extrusion plate 13 into the extrusion groove 12. In this embodiment, the inner wall of the extrusion groove 12 is spherical, and the outer wall of the extrusion plate 13 is spherical. Of course, the inner wall of the extrusion groove 12 and the outer wall of the extrusion plate 13 can also be conical.

[0069] like Figure 12 As shown, a method for measuring tension value of a signal acquisition device according to the second embodiment includes the following steps:

[0070] Step 21. Preliminary preparation: Install the support leg 15 and the friction-enhancing plate 11 on the end face of the anchor plate 16, install the jack 19 on the top of the support leg 15, install the tensioning nut 20 on the end face of the jack 19, and pass the tensioning rod 21 through the tensioning nut 20, the jack 19, and the support leg 15 in sequence;

[0071] Pass the tensioning member 1 through the anchor plate 16 and the friction-increasing plate 11 in sequence, clamp the outer wall of the tensioning member 1 with the first hoop body 2 and the second hoop body 3, and support the first hoop body 2 and the second hoop body 3 on the friction-increasing plate 11, pass the locking bolt 4 through the first hoop body 2 and the second hoop body 3 in sequence, sleeve the elastic member 6 on the locking bolt 4, screw the locking nut 5 into one end of the locking bolt 4 to press the elastic member 6, and pre-tighten the locking nut 5 to the set pre-tightening force value;

[0072] Insert the extrusion plate 13 into the tensioning member 1 and install it into the extrusion groove 12 of the first hoop body 2 and the second hoop body 3. Screw the clamping nut 14 into the tensioning member 1 to compress the extrusion plate 13. The tensioning member 1 and the clamping nut 14 are threadedly connected.

[0073] Connect the tension rod 21 to the tension member 1. The tension rod 21, the tension nut 20 and the tension member 1 are all threadedly connected.

[0074] Step 22. Loosen the compression nut 14;

[0075] Step 23. Control the jack 19 to extend the cylinder, the tensioning nut 20 and the tensioning rod 21 follow, the tensioning member 1 is pulled out by force, and the compression nut 14 is separated from the extrusion plate 13;

[0076] Step 24. After the jack 19 stops, tighten the compression nut 14 to transfer the tension to the first hoop body 2 and the second hoop body 3. The jack 19 retracts, and the tension nut 20 moves and is tightened;

[0077] Step 25. Repeat steps 22 to 24 until the tensioning member 1 is tensioned to the set tensioning force value;

[0078] Step 26. Tighten the compression nut 14, and the jack 19 contracts to convert the tension of the tension member 1 to the first hoop body 2 and the second hoop body 3. The first hoop body 2 and the second hoop body 3 are deformed by the force, thereby driving the elastic member 6 to deform. The detection sensor 7 of the elastic member 6 feeds back the detection data of the deformation of the elastic member 6 to the data acquisition module and the computer processing system 22. After being processed by the preset software, the current tension value of the tension member 1 is displayed.

[0079] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.

Preliminary preparation: install the support leg (15) and the friction-increasing plate (11) on the end surface of the anchor plate (16), install the jack (19) on the top of the support leg (15), install the tensioning nut (20) on the end surface of the jack (19), and pass the tensioning rod (21) through the tensioning nut (20), the jack (19), and the support leg (15) in sequence; The tensioning member (1) is passed through the anchor plate (16) and the friction-enhancing plate (11) in sequence, the first hoop body (2) and the second hoop body (3) are clamped to the outer wall of the tensioning member (1), and the first hoop body (2) and the second hoop body (3) are supported on the friction-enhancing plate (11), the locking bolt (4) is passed through the first hoop body (2) and the second hoop body (3) in sequence, the elastic member (6) is sleeved on the locking bolt (4), the locking nut (5) is screwed into one end of the locking bolt (4) to press the elastic member (6), and the locking nut (5) is pre-tightened to a set pre-tightening force value; Insert the extrusion plate (13) into the tensioning member (1) and install it into the extrusion groove (12) of the first hoop body (2) and the second hoop body (3), screw the clamping nut (14) into the tensioning member (1) to clamp the extrusion plate (13), and the tensioning member (1) and the clamping nut (14) are threadedly connected; The tensioning rod (21) is connected to the tensioning member (1), and the tensioning rod (21) is connected to the tensioning nut (20) and the tensioning member (1) by threaded connection; Step 22. Loosen the compression nut (14); Step 23. Control the jack (19) to extend the cylinder, the tensioning nut (20) and the tensioning rod (21) to follow, the tensioning member (1) is pulled out by force, and the clamping nut (14) is separated from the extrusion plate (13); Step 24. After the jack (19) stops, tighten the compression nut (14) to transfer the tension to the first hoop body (2) and the second hoop body (3). The jack (19) shrinks and the tension nut (20) moves and is tightened. Step 25. Repeat steps 22 to 24 until the tensioning member (1) is tensioned to a set tensioning force value; Step 26. Tighten the compression nut (14), and the jack (19) contracts to convert the tension of the tension member (1) to the first hoop body (2) and the second hoop body (3). The first hoop body (2) and the second hoop body (3) are deformed by the force, thereby driving the elastic member (6) to deform. The detection sensor (7) of the elastic member (6) feeds back the detection data of the deformation of the elastic member (6) to the data acquisition module and the computer processing system (22), and the current tension value of the tension member (1) is displayed after being processed by the preset software.
