Description

Technical Field

[0001] The present invention belongs to the technical field related to force measuring devices, and particularly relates to a device for real-time measurement of wire rope tension. Background Art

[0002] In a deployment mechanism released by a wire rope, the wire rope is tightly wound around the outer wall of a drum. As the drum rotates, the wire rope gradually unwinds or winds from the drum. During this process, the wire rope will simultaneously perform axial movement along the force direction and lateral movement along the axial direction of the drum. This kind of movement trajectory is a coupled two-dimensional movement. It is very difficult to obtain the internal tension value of the wire rope at all times through traditional measurement methods and tools. Therefore, a detection device capable of measuring the wire rope tension in a follow-up manner is specifically proposed. By adjusting the speed ratio of the gear and the lead screw, the sensor can always move with the wire rope and remain relatively stationary, and measure the internal tension of the wire rope at any time through the follow-up wheels and sensors installed thereon to solve the above problems. Summary of the Invention

[0003] In view of this, the present invention aims to propose a device for real-time measurement of wire rope tension to solve the problems in the prior art that it is necessary to continuously measure the internal tension value of the wire rope in real time; and it cannot be lightweight, which is not convenient for the device to be carried, transferred, and operated.

[0004] To achieve the above object, the technical solution of the present invention is realized as follows: A device for real-time measurement of wire rope tension includes a chassis, a guide rail assembly, a lead screw assembly, a follow-up device, a gear one, a gear two, a rope winding device, a follow-up wheel one, a follow-up wheel two, and a force measuring sensor. The chassis and the rope winding device are both installed on a platform. The guide rail assembly and the lead screw assembly are respectively installed at the bottom of the chassis. The guide rail assembly is installed on one side of the chassis. The follow-up device is installed in the middle of the lead screw assembly. The follow-up wheel two and the force measuring sensor are respectively installed on the follow-up device. The gear one is installed at one end of the lead screw assembly. The gear one is in meshing transmission with the gear two. The gear two is installed at one end of the rope winding device. The follow-up wheel one is also installed in the middle of the rope winding device.

[0005] Further, two connecting frames are respectively arranged on both sides of the bottom of the chassis. The bottom of each connecting frame is installed above a connecting seat. The guide rail assembly and the lead screw assembly are respectively installed at the bottom of the connecting seat.

[0006] Further, the guide rail assembly is used to provide support when one end of the follow-up device moves horizontally on the chassis.

[0007] Further, the lead screw nut of the lead screw assembly is connected to the follow-up device. The lead screw assembly is coaxially arranged with the gear one and rotates with the drive of the gear one.

[0008] Further, the rope winding device includes a drum and a number of mounting seats. The drum is mounted to the platform through the mounting seats, and one end of the drum is connected to Gear II.

[0009] Further, Gear II is coaxially arranged with the drum and is driven by the drum to rotate.

[0010] Further, it also includes a connecting rod. The first follower pulley is slidably sleeved on the connecting rod, and both ends of the connecting rod are respectively mounted to the mounting seats installed at both ends of the drum. The first follower pulley is used for storing and releasing the steel wire rope.

[0011] Further, the second follower pulley is used for receiving the tension of the steel wire rope and transmitting it to the chassis.

[0012] Further, the force measuring sensor is used for receiving the force transmitted by the second follower pulley and displaying the tension of the steel wire rope in real time.

[0013] Further, the measuring method of the measuring device includes: S1. First, the platform draws out the steel wire rope from the first follower pulley and continuously feeds the wire. While feeding the wire, the first follower pulley moves horizontally along with the steel wire rope; S2. The feeding of the steel wire rope drives the drum to rotate. The drum then drives Gear I and Gear II, and finally drives the lead screw assembly to rotate; S2. Through the speed ratio of Gear I, Gear II and the lead screw assembly, the lead screw assembly drives the follower device to move horizontally, and the speed matches the horizontal moving speed of the steel wire rope, so that the second follower pulley is always tangent to the steel wire rope; S4. While the steel wire rope is feeding, the magnitude of the internal tension thereof is received by the second follower pulley and then transmitted to the force measuring sensor, so that the force measuring sensor displays the tension of the steel wire rope in real time.

[0014] Compared with the prior art, the real-time steel wire rope tension measuring device of the present invention has the following advantages: (1) For the real-time steel wire rope tension measuring device of the present invention, in terms of safety, after the steel wire rope is fed, it is completely driven by the mechanism itself without manual operation, which well ensures safety.

[0015] (2) For the real-time steel wire rope tension measuring device of the present invention, in terms of working accuracy, the horizontal movement of the follower device is controlled by the accuracy of the lead screw itself, which can well ensure the accuracy of the data of the measuring sensor.

[0022] The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] AsFigures 1 to 2 As shown in the figure, a real-time wire rope tension measuring device includes a chassis 1, a guide rail assembly 2, a lead screw assembly 3, a follower device 4, a first gear 5, a second gear 6, a rope winding device 7, a first follower wheel 8, a second follower wheel 9, and a force measuring sensor 10. By adjusting the speed ratio of the gear assembly and the lead screw assembly 3, the measuring device can follow the path of the wire rope on the rope winding device 7 in real time, thereby realizing continuous measurement of the tension value inside the wire rope.

[0024] 1) The chassis 1 is a structural part installed on the platform. The guide rail assembly 2 and the lead screw assembly 3 are installed on the chassis 10. Two connecting brackets 11 are respectively arranged on both sides of the bottom of the chassis 1, and the bottom of each connecting bracket 11 is installed on a connecting seat 12. One side of the bottom of the connecting seat 12 is installed with the guide rail assembly 2.

[0025] 2) The guide rail assembly 2 is installed on the connecting seat 12 and is used to provide support when one end of the follower device 4 moves horizontally on the chassis 1.

[0026] 3) The lead screw assembly 3 is installed on the connecting seat 12. The follower device 4 is installed on the lead screw nut of the lead screw assembly 3. At the same time, driven by the first gear 5, the lead screw assembly 3 rotates, thereby driving the follower device 4 to move horizontally.

[0027] 4) The follower device 4 is installed on the guide rail assembly 2 and the lead screw assembly 3. The second follower wheel 9 and the chassis 1 are both installed on the follower device 4.

[0028] 5) The first gear 5 is installed on the lead screw assembly 3 and is used to receive the drive of the second gear 6 and then drive the lead screw assembly 3.

[0029] 6) The second gear 6 is installed on the rope winding device 7. Driven by the rope winding device 7, the second gear 6 drives the first gear 5. The size ratio of the first gear 5 and the second gear 6 can be determined according to the actual situation.

[0030] 7) The rope winding device 7 is a structural part. The rope winding device 7 includes a drum 71 and a number of mounting seats 72. The drum 71 is installed on the platform through the mounting seats 72. The first follower wheel 8 is installed on one side of the drum 71 and is used for storing and releasing the wire rope. One end of the drum 71 is connected to the second gear 6.

[0031] 8) For the first follower wheel 8, the follower device 4 is also provided with a connecting rod 41. This part is slidably sleeved on the connecting rod 41. Both ends of the connecting rod 41 are respectively installed on the mounting seats 72 installed at both ends of the drum 71 and are used for releasing the wire rope and can move horizontally on the rope winding device 7 according to the wire rope routing.

[0032] 9) The second follower wheel 9 is installed on the follower device 4 and is used to receive the tension of the wire rope and transmit it to the chassis 1.

[0033] 10) The force measuring sensor 10 is installed on the follower device 4 and is used to receive the force transmitted by the second follower wheel 9 and analyze it, so as to display the tension of the wire rope in real time.

[0034] The driving principle of a real-time wire rope tension measuring device: The wire rope wound on the wire winding device 7 is released through the first follower wheel 8. The first follower wheel 8 moves horizontally simultaneously with the wire routing of the wire rope, so that the wire rope always moves along the force application direction without skewing in other directions. At the same time, the wire routing of the wire rope drives the winding drum on the wire winding device 7 to rotate, thereby driving the second gear 6, then driving the first gear 5, and finally driving the lead screw of the lead screw assembly 3 to rotate. Through the speed ratio adjustment of the gears and the lead screw, the follower device 4 is driven to follow the horizontal movement of the wire rope in real time, so that the second follower wheel 9 is always tangent to the wire rope. While the second follower wheel 9 is following the wire routing of the wire rope, it receives the tension inside the wire rope in real time and transmits the magnitude of the force to the chassis 1, and the chassis 1 displays the magnitude of the wire rope tension in real time according to the feedback of the second follower wheel 9.

[0035] Embodiment 1 The implementation process of a real-time wire rope tension measuring device is as follows: 1) First, the platform draws out the wire rope from the first follower wheel 8 and continuously routes it. While routing, the first follower wheel 8 moves horizontally following the wire rope; 2) The wire routing of the wire rope drives the reel 71 to rotate, and the reel 71 drives the first gear 5 and the second gear 6, and finally drives the lead screw assembly 3 to rotate; 3) Through the speed ratio of the first gear 5, the second gear 6 and the lead screw assembly 3, the lead screw assembly 3 accurately drives the follower device 4 to move horizontally, and the speed matches the horizontal moving speed of the wire rope, so that the second follower wheel 9 is always tangent to the wire rope; 4) While the wire rope is being routed, the magnitude of the internal tension of the wire rope is received by the second follower wheel 9 and then transmitted to the force measuring sensor 10, so that the force measuring sensor 10 displays the magnitude of the wire rope tension in real time.

[0036] Advantages of the present invention: In terms of safety, after the wire rope is routed, it is completely driven by the mechanism itself without manual operation, which well ensures safety; in terms of working accuracy, the horizontal movement of the follower device is controlled by the accuracy of the lead screw itself, which can well ensure the accuracy of the measurement sensor data; in terms of equipment maintenance, the number of components of the mechanism is appropriate and the structure is simple and clear, which ensures convenience in maintenance.
