Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be further described in detail below with reference to specific examples and accompanying drawings. Exemplary embodiments will be described in detail here, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] An anti-torsion device for a wire rope load sensor includes a support 100, a sensor connector 200, a wire rope connector 300, and a counterweight assembly 400, wherein:

[0028] Sensor connector 200 is configured to connect to a sensor that measures the loading force of a wire rope.

[0029] Wire rope connector 300 is configured to connect wire ropes;

[0030] Support member 100 is configured to connect sensor connector 200 and wire rope connector 300;

[0031] The counterweight assembly 400 is configured to provide counterweight to the sensor connector 200;

[0032] Specifically, two support members 100 are provided. Each support member 100 has a sensor connector 200 fixedly connected to each end and a wire rope connector 300 rotatably connected to each end. The bottoms of the two support members 100 are hinged to the two ends of the same counterweight assembly 400, which transmits the force on the wire rope to the wire rope connector 300. Then, through the rotational connection between the wire rope connector 300 and the support member 100, the tension on the wire rope continues to be received by the support member 100, while the torsional force is released through the rotational motion. The support member 100 continues to transmit the tension to the sensor connector 200 fixedly connected to the support member 100. Thus, the sensor detects the force on the sensor connectors 200 on both sides, determines the actual force on the wire rope, reduces the damage of torsional force to the sensor and its detection accuracy, and improves the accuracy of the test.

[0033] In some embodiments, the support member 100 includes a mounting housing 110, a mounting block 120, and a fixing pin 130. One end of the mounting housing 110 is open to form a mounting notch for accommodating the wire rope connector 300. The mounting block 120 is fixedly connected to the mounting notch of the mounting housing 110 by the fixing pin 130, so that the wire rope connector 300 can be detachably connected to the support member 100 for easy maintenance and replacement in the future.

[0034] In some embodiments, the wire rope connector 300 includes a rotating column 310 rotatably connected to the support member 100, and rotating ears 320 and hemispherical caps 330 fixedly connected to both ends of the rotating column 310. The rotating ears 320 are provided with binding holes for binding the wire rope. The outer diameter of the hemispherical cap 330 is larger than the outer diameter of the rotating column 310 and larger than the height of the mounting notch. The outer diameter of the rotating column 310 is smaller than the height of the mounting notch, so that the rotating ears 320 can rotate freely on the support member 100 without producing any displacement other than rotation. This releases the rotational torque of the wire rope and reduces the error of the rotational torque on the sensor data, ensuring the accuracy of the tension transmission.

[0035] In some embodiments, the mounting block 120 has a groove on its inner side that mates with the mounting notch. The groove and the mounting notch together form a pivot hole for a cylinder. The pivot hole is used to accommodate the rotating column 310, thereby better fitting the shape of the rotating column 310 and reducing rotational friction loss.

[0036] In some embodiments, the sensor connector 200 includes a mounting base 210, which is vertically fixed to the support member 100. The mounting base 210 has a connection hole for connecting a sensor. Optionally, the mounting base 210 can also be detachably connected to the support member 100, but it needs to be connected by a detachable method such as threaded fixing to ensure the stability of tensile force transmission and facilitate future maintenance.

[0037] In some embodiments, the outer side of the mounting base 210 is provided with rounded corners to protect the sensor and reduce damage to the user during sensor installation and maintenance.

[0038] In some embodiments, the counterweight assembly 400 includes a connecting rod 410 and a gravity disk 420. Two connecting rods 410 are provided, and the two connecting rods 410 are respectively hinged to the center positions on both sides of the counterweight disk. By setting the counterweight assembly 400, the support members 100 on both sides maintain positional stability under the influence of gravity of the gravity disk 420. By using the rigid connecting rods 410 and the hinged setting, the test results can be avoided from being affected by the sensor connection wire being entangled due to the rotation of the sensor.

[0039] In some embodiments, the bottom of the support member 100 is provided with a weight plate connecting seat 140, and the end of the connecting rod 410 is hinged to the weight plate connecting seat 140. The weight plate connecting seat 140 and the support member 100 are rigid structures that are fixedly connected to ensure that no other torsional torque is reintroduced during the hinge process.
