Description

Technical Field

[0001] This invention relates to the field of tension sensor technology, specifically to intelligent tension sensors. Background Technology

[0002] The pressure-side tension sensor is a type of tension sensor. It is a pressure sensor with high reliability, good interchangeability, and easy use, suitable for measuring and controlling the tension of wire ropes.

[0003] Most commercially available pressure-side tension sensors employ a dual-hole shear beam structure, offering convenient installation, simple operation, and easy maintenance. They are specifically designed for measuring the tension of steel wire ropes. The wire rope is fixed to the sensor via a clamping seat. When the wire rope is subjected to tension, this force is transmitted to the sensor through guide wheels, enabling the detection of tension at both ends of the rope. Currently, pressure-side tension sensors typically use screws for fixing, resulting in a cumbersome disassembly and assembly process. Furthermore, the fixed size of the arc groove on the clamping seat prevents optimal clamping for ropes of varying thicknesses. Most strain gauge sensors lack limiting clamping devices, making it easy for the rope to vibrate or shift position when subjected to external forces, preventing close contact between the rope and the sensing wheels and leading to errors in tension detection. Current sensors rely on wired connections for information transmission; however, malfunctions or damage to the wiring can result in data loss or transmission failure. Therefore, appropriate technical solutions are needed to address these issues. Summary of the Invention

The screw-fixed clamping seat has a cumbersome and time-consuming disassembly and assembly process. 2. The fixed-size arc groove on the clamping seat cannot achieve optimal clamping effect when dealing with ropes of different thicknesses. 3. The sensor wheel lacks a limiting clamping device, making it prone to poor contact between the rope and the wheel due to external forces, affecting tension detection. 4.

[0015] (III) Beneficial Effects

[0016] 1. The clamping seat and the connecting seat of this sensor are locked by a rotary screw head. When disassembling and assembling the fixing frame, you only need to manually turn the rotary screw head to complete the disassembly and assembly. It is fast and efficient, avoiding the cumbersome process of disassembling and assembling screws with external tools.

[0017] 2. The clamping seat of this sensor is equipped with a clamping component, which is used to clamp and fix the rope. The arc groove of the clamping seat only serves to limit the rope. When clamping the rope, simply rotate the rotating rod manually. The second screw drives the clamping plate to clamp and fix the rope through the threaded transmission. This method can provide clamping and fixing for ropes of different thicknesses, solving the limitation problem of direct fixing by the clamping seat.

[0018] 3. The sensor's sensing wheel has a limiting clamping device fitted into its limiting seat. For ropes of different thicknesses, the clamping sleeve is extended and retracted accordingly. After extension and retraction, the clamping sleeve is fixed to the limiting seat with screws. The clamping wheel on the clamping sleeve provides clamping to the rope. When the rope is stretched or retracted under force, the clamping wheel and sensing wheel rotate accordingly, without affecting tension detection. The design of the wheel clamping structure avoids rope vibration and positional shift, preventing poor contact between the rope and sensing wheel and affecting tension detection.

[0019] 4. The information transmission method of this sensor adopts an integrated approach of line transmission and network remote transmission. During the line transmission process, the control motherboard in the information transmission box will also collect the tension detection information and transmit it remotely to the control terminal for storage and backup via the network signal transmitter, thus avoiding the problem of loss of detection information due to line failure or damage.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-8This invention provides a technical solution: an intelligent tension sensor, including a sensing device and a fixing frame.

The sensing device is located inside the strain gauge 1. The clamping seat 2 and the connecting seat 5 are located at the top and bottom of the strain gauge 1, respectively. The connecting seat 5 has first fitting holes 11 on both sides. The clamping seat 2 and the connecting seat 5 are locked and fixed by the connecting frames 6 on both sides. One end of the strain gauge 1 is fitted with a hexagonal nut, and the other end has a wiring connection hole 8. The strain gauge 1 has a first limiting seat 3, a second limiting seat 4, and a display screen 10.

The base of the first limiting seat 3 and the second limiting seat 4 each have a slot and a third fixing hole 30. The second fitting hole 24... The device includes a sensing wheel 25 connected to a sensing device. A clamping sleeve 26 is fitted onto both the first limiting seat 3 and the second limiting seat 4. A clamping wheel 27 is housed within the clamping sleeve 26 and is connected to the inner walls of both sides of the clamping sleeve 26 via rotating screws. Fitting pieces 28 are welded to both sides of the clamping sleeve 26 and engage with slots. Each fitting piece 28 has a second fixing hole 29. A clamping assembly 17 is fitted onto the clamping seat 2. The clamping seat 2 has an arc-shaped groove 18 and a rotating screw head 33 on its seat body. The rotating screw head 33 is located on both sides of the arc-shaped groove 18. The arc-shaped groove 18 has a threaded hole 19. The clamping assembly 17 includes a rotating screw disc 20, a second screw 21 and a clamping plate 22. The clamping plate 22 is located in the arc-shaped groove 18. One end of the second screw 21 is welded to the rotating screw disc 20, and the other end passes through the threaded hole 19 and is connected to the clamping plate 22. The rotating screw disc 20 has rotating rods at both ends.

[0031] The clamping wheel 27 and the sensing wheel 25 are the same size and corresponding in position. A rubber sleeve is nested on the wheel body of the clamping wheel 27, and a rope fitting groove is provided on the wheel body of the sensing wheel 25, with a rubber gasket bonded inside the groove. The identical size of the clamping wheel and sensing wheel ensures the consistency of the wheel structure. The rope fitting groove on the sensing wheel provides a limit for the rope, and the clamping wheel presses the rope on the sensing wheel, ensuring that the rope at the detection end is not affected by external forces, thus preventing poor contact with the sensing wheel.

[0032] The second fixing holes 29 are evenly distributed longitudinally on the fitting piece 28. The second fixing holes 29 and the third fixing holes 30 are the same size and corresponding in position. The second fixing holes 29 are screw holes, and the third fixing holes 30 are through holes.

The connecting frame can limit and fix the clamping seat, and at the same time, the connecting end on the first screw can fix the connecting seat to the external equipment, thereby achieving the fixation of the entire fixing frame.

[0034] A rotating seat 23 is provided between the clamping plate 22 and the second screw 21. The rotating seat 23 is welded to the clamping plate 22, and the rotating end of the rotating seat 23 is fixed to the second screw 21 by screws. A rubber gasket is adhered to the clamping surface of the clamping plate 22. The rotating seat allows the clamping plate and the second screw to rotate independently, avoiding the situation where the clamping plate rotates with the second screw during the threaded transmission of the second screw, which would affect the clamping position of the clamping plate.

[0035] The control motherboard 32 is a PCB integrated circuit board. A network card, a line connector, and an information acquisition module are connected to the pins of the control motherboard 32. The line connector is connected to the interface of the information acquisition module, the sensor device, and the signal transmitter 31 via connecting cables. The signal transmitter can realize mode conversion between information and signal, and can realize remote signal transmission with the help of a network. The control motherboard can realize the acquisition and transmission of tension detection information.

[0036] The control motherboard 32 is a PCB integrated circuit board. A network card and a line connection terminal are connected to the pins of the control motherboard 32. The line connection terminal connects to the interface of the sensing device and the interface of the signal transmitter 31 via connecting cables. Network connectivity is achieved through the network card on the control motherboard, and the line connection terminal enables the wiring connection between the control motherboard and the device.

[0037] The signal transmitter 31 is a wireless network transmitter, which is remotely connected to the control terminal via a network. This remote connection enables remote information transmission, allowing detected information to be stored and backed up by the control terminal, thus preventing information loss due to line failures or damage.

[0038] Working principle: When connecting the rope to the sensor, firstly, the first screw 12 on the connecting frame 6 and the first mating hole 11 on the connecting seat 5 are threaded together to achieve through-thread transmission, thus fixing the connecting frame 6 to the connecting seat 5. The detection part of the rope is then connected to the rope mating groove of the sensing wheel 25 in the first limit seat 3 and the second limit seat 4 for limiting. Then, the clamping sleeve 26 is fitted into the first limit seat 3 and the second limit seat 4 respectively. During fitting, the mating pieces 28 on both sides of the clamping sleeve 26 are embedded into the slots on both sides of the limit seat. By extending and retracting the clamping sleeve 26, the pressure is increased. The clamping wheel 27 on the tight sleeve 26 clamps the rope body. A screw passes through the third fixing hole 30 on the limit seat and locks it into the corresponding second fixing hole 24 on the fitting piece 28, thus fixing the limit seat and the clamping sleeve 26. After fixing the detection rope part, the middle part of the detection rope needs to be clamped and fixed. First, the clamping seat 2 and the connecting seat 5 need to be connected. During connection, the first screw 12 on the connecting frame 6 is threaded into the first fitting holes 11 on both sides of the connecting seat 5 to fix the connecting frame 6 and the connecting seat 5. Then, the two screws on the clamping seat 2... The rotating screw head 33 on the side aligns with the locking rod 14 on the connecting brackets 6 on both sides of the connecting seat 5. By rotating the rotating screw head 33, the rotating screw head 33 is locked and fixed with the locking hole on the locking rod 14, thus completing the fixation of the clamping seat 2 and the connecting seat 5. At this time, the middle part of the detection rope will be located in the arc groove 18 of the clamping seat 2. The rotating rod on the rotating screw disc 20 drives the second screw 21 to rotate. Under the transmission of the thread, the clamping plate 22 connected to the second screw 21 clamps and fixes the middle part of the detection rope. Finally, the connected integrated wire and strain gauge are connected. The wiring connection hole 8 on 1 is connected to realize the connection between the control terminal and the sensing device. When the rope is stretched by force, the sensing wheel 25 and the pressure wheel 27 will rotate accordingly. Since the sensing wheel 25 is connected to the sensing device inside the strain gauge 1, the sensing device will transmit the collected information to the control terminal through the integrated line. During the transmission of information, the information acquisition module on the control motherboard 32 will also collect the detected information. With the help of the network card and signal transmitter, remote network transmission is realized. After receiving the remotely transmitted information, the control terminal will store and back up the information.

[0039] The present invention comprises a strain gauge 1, a clamping seat 2, a first limiting seat 3, a second limiting seat 4, a connecting seat 5, a connecting frame 6, a hexagonal nut 7, a wiring connection hole 8, an information transmission box 9, a display screen 10, a first fitting hole 11, a first screw 12, a rod sleeve 13, a locking rod 14, a connecting end 15, a first fixing hole 16, a clamping assembly 17, an arc groove 18, a threaded hole 19, a rotating screw disc 20, a second screw 21, a clamping plate 22, a rotating seat 23, a second fitting hole 24, a sensing wheel 25, a clamping sleeve 26, a clamping wheel 27, a fitting plate 28, a second fixing hole 29, a third fixing hole 30, a signal transmitter 31, a control main board 32, and a rotating screw head 33. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by the present invention is that the clamping seat with a screw-fixed structure has a cumbersome disassembly and assembly process, which is time-consuming and labor-intensive. 2. The fixed-size arc groove on the clamping seat cannot achieve optimal clamping effect when dealing with ropes of different thicknesses. 3. The sensor wheel lacks a limiting clamping device, making it susceptible to poor contact between the rope and the wheel due to external forces, thus affecting tension detection. 4. The traditional cable transmission method is limited. Cable malfunctions or damage can easily lead to data loss and transmission failures. This invention addresses this by using a rotary screw to lock the clamping seat and connecting seat. Disassembly and assembly of the mounting bracket can be completed simply by manually rotating the screw, resulting in high speed and efficiency and avoiding the cumbersome process of using external tools. The clamping seat of this sensor is equipped with a clamping component, which clamps and secures the cable. The arc-shaped groove of the clamping seat only serves to limit the cable's position. To clamp the cable, simply rotate the rotating rod manually; the second screw, through threaded transmission, drives the clamping plate to clamp and secure the cable. This method can provide clamping and securing for cables of different thicknesses, overcoming the limitations of direct clamping. The sensor's sensing wheel... The limiting seat is fitted with a limiting clamping device. For ropes of different thicknesses, the clamping sleeve is extended and retracted accordingly. After extension and retraction, the clamping sleeve is fixed to the limiting seat with screws. The clamping wheel on the clamping sleeve provides clamping to the rope. When the rope is stretched or retracted under force, the clamping wheel and the sensing wheel rotate accordingly, without affecting tension detection. The design of the wheel clamping structure avoids rope vibration and positional displacement, preventing poor contact between the rope and the sensing wheel and affecting tension detection. The sensor's information transmission method integrates in-line transmission and remote network transmission. During in-line transmission, the control motherboard in the information transmission box also collects tension detection information and transmits it remotely to the control terminal via a signal transmitter through the network for storage and backup, avoiding the problem of information loss due to in-line failure or damage.

[0040] The information transmitter model involved in this case is SZ-FC20S, and the control motherboard model is 6FC5357-0BB35-0AA0.
