Description

Technical Field

[0001] This utility model relates to the field of magnetic flux sensor technology, and in particular to a fixing device for a single steel strand magnetic flux sensor. Background Technology

[0002] A magnetic flux sensor is a non-contact device for measuring cable tension. It employs a sleeve-type structure, with the cable being measured passing through the sensor, and the sensor fixed to the cable during measurement.

[0003] Traditional methods for fixing magnetic flux sensors involve wrapping them with tape or using metal clamps. These methods have the following drawbacks:

[0004] 1. In the long run, traditional methods will cause the material to age and fall off, making it impossible to fix the position.

[0005] 2. The installation space is small, making installation inconvenient. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a fixing device for a single steel strand magnetic flux sensor, which aims to solve the technical problems in the prior art that the magnetic flux sensor cannot be well fixed at the detection position of the steel strand and is inconvenient to install.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0008] A single-strand steel strand magnetic flux sensor fixing device includes a magnetic flux sensor fixing device body, which is installed between a magnetic flux sensor and a working anchor plate. The magnetic flux sensor fixing device body includes a mounting part and a connecting part concentrically connected to the mounting part. The outer diameter of the mounting part is larger than the outer diameter of the connecting part. A straight hole for avoiding the steel strand is provided through the center of the magnetic flux sensor fixing device body. The mounting part has a through hole that matches the threaded hole on the magnetic flux sensor. The mounting part has a wire-passing hole for avoiding the cable. The connecting part has a plurality of expansion joints spaced along the axial direction, which divide the connecting part into a plurality of connecting pieces. A plurality of reverse tooth structures are arrayed on the outer side of the connecting pieces along the axial direction. The magnetic flux sensor fixing device body is an integrally formed structure.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the single steel strand magnetic flux sensor fixing device is installed at one end of the magnetic flux sensor, forming an integral whole with the magnetic flux sensor. It can then be inserted into the steel strand together with the magnetic flux sensor during installation. Then, the connecting part only needs to be inserted into the mounting hole of the working anchor plate, and under the action of the reverse tooth structure, it is firmly fixed to the working anchor plate, thereby completing the fixing of the magnetic flux sensor. It can be seen that by installing this new device, the magnetic flux sensor can be quickly fixed, and the operation is convenient and reliable.

[0010] According to one aspect of the above technical solution, there are three expansion joints.

[0011] According to one aspect of the above technical solution, the through hole is a countersunk hole.

[0012] According to one aspect of the above technical solution, the connecting part is provided with a clearance groove that matches the through hole.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] See Figures 1 to 2This utility model provides a single-strand steel strand magnetic flux sensor fixing device, including a magnetic flux sensor fixing device body 1. The magnetic flux sensor fixing device body 1 is installed between a magnetic flux sensor 2 and a working anchor plate. The magnetic flux sensor fixing device body 1 includes a mounting part 11 and a connecting part 12. The outer diameter of the mounting part 11 is larger than the outer diameter of the connecting part 12. A straight hole 13 for a steel strand to pass through is provided between the mounting part 11 and the connecting part 12. Both the mounting part 11 and the connecting part 12 are hollow cylindrical structures and are coaxially connected. A through hole 111 matching the threaded hole on the magnetic flux sensor 2 is provided on the mounting part 11. During installation, the magnetic flux sensor fixing device body 1 is fixed to the magnetic flux sensor 2 by passing a bolt through the through hole 111, thus completing the connection between the magnetic flux sensor fixing device body 1 and the magnetic flux sensor 2. A wire hole 112 is provided on the mounting part 11 for passing through the cable 21 on the magnetic flux sensor 2. After the magnetic flux sensor 2 is installed on the magnetic flux sensor fixing device body 1, it is inserted into the steel strand. It should be noted that one end of the connecting part 12 needs to be inserted towards the end of the working anchor plate. This allows the connecting part 12 of the magnetic flux sensor fixing device body 1 to be inserted into the through hole of the working anchor plate. Generally, the outer diameter of the connecting part 12 is equal to the inner diameter of the through hole of the working anchor plate. However, in this embodiment, the outer diameter of the connecting part 12 is provided with a toothed structure 123 to increase the friction. This makes the outer diameter of the entire connecting part 12 larger than the inner diameter of the through hole, which is not convenient for direct insertion. Therefore, several expansion joints 121 are provided at intervals on the connecting part 12 to divide the connecting part 12 into several uniform connecting pieces 122. In this way, when the connecting part 12 is inserted into the through hole of the working anchor plate, the connecting pieces 122 can retract towards the axial end, making it easier to insert into the through hole. This achieves a quick connection between the magnetic flux sensor fixing device body 1 and the working anchor plate, thereby quickly fixing the magnetic flux sensor 2 to one side of the working anchor plate. Therefore, it can be seen that installing this new type of magnetic flux sensor 2 makes installation simpler and more efficient. In addition, this new type of sensor has a one-piece molded structure, which facilitates mass production.

[0024] See Figure 1 The expansion joint 121 can be two, three, or more. In this embodiment, the expansion joint 121 is set to three. The three expansion joints 121 divide the connecting part 12 into three connecting pieces 122, which not only ensures the structural strength of the connecting part 12 itself, but also prevents jamming in the through hole of the inserted working anchor plate. Preferably, the expansion joint 121 is three.

[0025] Furthermore, the through hole 111 is a countersunk hole. By setting it as a countersunk hole, after the mounting part 11 is connected to the magnetic flux sensor 2 by bolts, the bolt head is flush with one end of the mounting part 11. This is not only aesthetically pleasing, but more importantly, it ensures that after the connecting part 12 is inserted into the working anchor plate, one end of the mounting part 11 can fit against the surface of the working anchor plate, forming a unified connection and reducing radial wobbling. It should be noted that in this embodiment, the through hole 111 is located near the outer side of the connecting part 12. In order to smoothly install the screw, a clearance groove 124 needs to be provided on the connecting part 12. At the same time, in order not to damage the structural strength of the connecting part 12, the clearance groove 124 is set along the direction of the expansion joint 121. It can be understood that there are three through holes 111, and they are set near the direction of the expansion joint 121. Specifically, the connecting part 12 is provided with clearance grooves 124 that match the through holes 111.

[0026] See Figure 1 Furthermore, the inverted tooth structure 123 has a triangular cross-section and is inclined toward the mounting part 11. By setting the inverted tooth structure 123 in the connecting part 12, after the connecting part 12 is inserted into the through hole of the working anchor plate, the inverted tooth structure 123 firmly grips the inner wall of the through hole, making the magnetic flux sensor fixing device body 1 more firmly connected to the working anchor plate and less likely to fall off outward.

[0027] See Figure 2 The wire hole 112 can be a closed circular structure or a semi-open circular structure. However, when one end of the sensor cable 21 is short, the closed circular structure allows for quick assembly and disassembly of the magnetic flux sensor mounting device body 1. When one end of the sensor cable 21 is long, the closed circular wire hole 112 needs to pass through the entire length of the sensor cable 21 during installation and disassembly, making the assembly and disassembly more time-consuming and laborious. In this embodiment, the wire hole 112 is set in a semi-open shape. When assembling and disassembling the magnetic flux sensor mounting device body 1, the cable 21 only needs to enter and exit from the open end of the wire hole 112, making the assembly and disassembly more convenient and quick. Preferably, the wire hole 112 passes through the edge of the mounting part 11 to form an open end. The width of the open end of the wire hole 112 is slightly smaller than the diameter of the wire hole 112. By setting the open end of the wire hole 112 slightly smaller, the wire hole 112 has a certain cable 21 clamping function.

[0028] Furthermore, the magnetic flux sensor fixing device body 1 is made of nylon material, which has the characteristics of being wear-resistant and not easily aged, thus reducing the number of maintenance times after the magnetic flux sensor 2 is installed.

[0029] In summary, the single-strand magnetic flux sensor fixing device in the above embodiments of this utility model bolts the magnetic flux sensor to the mounting part to form a whole, and then inserts the connecting part directly into the through hole of the working anchor plate by plugging, thus completing the rapid fixing of the magnetic flux sensor. In addition, since the main body of the magnetic flux sensor fixing device is made of one-piece molded nylon material, this new invention has the characteristics of wear resistance, aging resistance and easy mass production.
