Description

Technical Field

[0001] This utility model relates to the technical field of installation of compressor shaft vibration detection probes in confined spaces, and in particular to a magnetic mounting sleeve for a wire harness probe in a confined space. Background Technology

[0002] In numerous fields such as power, petroleum, chemical, and metallurgy, monitoring the operational status of large rotating machinery such as steam turbines, blowers, compressors, and air separation units is crucial. Parameters such as radial vibration, axial displacement, and shaft speed of these large rotating machinery shafts typically require real-time online measurement using probes. In the measurement system, extension cables are used to connect the probe and the preamplifier (or transmitter). However, during actual equipment installation and maintenance, the probes are usually installed in confined spaces, which presents numerous difficulties for probe installation and removal.

[0003] On the one hand, the probe needs to be rotated during installation, but the excessively long cable is inconvenient to rotate with the probe and is very easy to break. This not only increases the equipment maintenance cost, but also affects the normal operation of the equipment.

[0004] On the other hand, the confined space poses a significant obstacle to operation during the disassembly and assembly of probes before and after equipment maintenance. Furthermore, traditional tools are not designed to ensure ease and speed when twisting the probes, and there is also a risk of nuts and screws coming loose, further increasing the difficulty of installation and working time.

[0005] In summary, existing installation tools and methods cannot meet the requirements for assembling probes with wire harnesses in confined spaces. Therefore, there is an urgent need to develop a new type of magnetic sleeve for assembling probes with wire harnesses in confined spaces, in order to improve work efficiency and installation accuracy, reduce the labor intensity of workers, and ensure the normal operation and maintenance of equipment. Utility Model Content

It has a simple structure, is easy to use, effectively improves work efficiency, and effectively reduces the labor intensity of workers.

[0007] To achieve the above objectives, this utility model provides the following solution:

[0008] This utility model provides a magnetic suction sleeve for a wire harness probe in a confined space, comprising: a sleeve body and a magnetic suction assembly. The sleeve body has a first end and a second end disposed opposite to each other. The first end is provided with a drive interface for connection to an external torque tool, and the second end is provided with a working interface. The inner wall configuration of the working interface is adapted to engage with the probe or its locking element to transmit torque. An axial groove is formed on the circumferential sidewall of the sleeve body. The axial groove extends from the working interface toward the drive interface and communicates with the working interface to lead out the extension cable of the probe. The magnetic suction assembly is disposed in the sleeve body and adjacent to the working interface for magnetically holding the probe or locking element.

[0009] Preferably, the drive interface is an inner square hole.

[0010] Preferably, the working interface is an internal hexagonal hole.

[0011] Preferably, the axial groove is an oblong through hole or a rectangular through hole.

[0012] Preferably, the magnetic attraction component is a ring-shaped permanent magnet, which is fixed to the sleeve body by pressing or bonding.

[0013] Preferably, the adsorption end face of the annular permanent magnet is coplanar with the bottom end face of the working interface or is recessed inward from the working interface toward the driving interface.

[0014] Preferably, the sleeve body is made of non-magnetic metal material or high-strength engineering plastic.

[0015] This utility model also provides a probe assembly tool assembly, including: a magnetic assembly sleeve as described in any of the above claims; and a drive handle, one end of which has a connector that matches the drive interface.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] This invention provides a magnetic attachment sleeve for wire harness probes in confined spaces. By providing a drive interface, operators can easily use an external torque tool to provide rotational power to the sleeve body, making operation more labor-saving and convenient. The engaging design between the working interface and the probe or locking element ensures effective torque transmission during assembly, improving the accuracy of installation and disassembly.

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

[0027] The purpose of this invention is to provide a magnetic attachment sleeve for wire harness probes in confined spaces, in order to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively improves work efficiency, and effectively reduces the labor intensity of workers.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This utility model provides a magnetic charging sleeve for use with wire harness probes in confined spaces, such as... Figures 1-6 As shown, the device includes: a sleeve body 1 and a magnetic suction assembly 5. The sleeve body 1 has a first end and a second end arranged opposite to each other. The first end is provided with a drive interface 2 for connecting to an external torque tool, and the second end is provided with a working interface 3. The inner wall configuration of the working interface 3 is adapted to engage with a probe or its locking element to transmit torque. An axial groove 4 is formed on the circumferential side wall of the sleeve body 1. The axial groove 4 extends from the working interface 3 toward the drive interface 2 and communicates with the working interface 3 to lead out the probe's extension cable. The magnetic suction assembly 5 is disposed inside the sleeve body 1 and adjacent to the working interface 3 for magnetically holding the probe or locking element. By setting up the drive interface 2, the operator can easily use an external torque tool to provide rotational power to the sleeve body 1, making the operation more labor-saving and convenient; the engaging design of the working interface 3 with the probe or locking element ensures that the torque can be effectively transmitted during the assembly process, improving the accuracy of installation and disassembly; the axial groove 4 provides a dedicated channel for cable lead-out, avoiding the extension cable being squeezed or twisted in a confined space, and protecting the cable from damage; the magnetic suction component 5 can attract the probe or locking element, preventing it from falling in a confined space, reducing installation obstacles and time waste caused by lost parts.

[0030] In a preferred embodiment, the drive interface 2 is an inner square hole. The inner square hole, as the drive interface 2, has strong versatility and can be adapted to a variety of common square head external torque tools, such as common square handle wrenches. There is no need to customize special tools, which reduces the threshold and cost of tool use and makes it convenient for operators to quickly obtain and operate the adapted tools in different environments.

[0031] In a preferred embodiment, the working interface 3 is an internal hexagonal hole. The internal hexagonal hole working interface 3 can be closely adapted to the hexagonal structure commonly found on probes or locking elements, and has better stability and accuracy when transmitting torque. It can more accurately tighten or loosen the probe and related locking elements, avoiding slippage or uneven torque transmission caused by interface mismatch, and ensuring the quality of probe installation and disassembly.

[0032] In a preferred embodiment, the axial groove 4 is an oblong or rectangular through hole. The design of the axial groove 4 with an oblong or rectangular through hole provides sufficient space to ensure that the extension cable of the probe can be led out smoothly, avoiding the cable being difficult to pass through or bending due to the hole being too small. On the other hand, the regular shape facilitates processing and manufacturing, and at the same time, it is easier to organize and arrange the cable route when leading out the cable, making it easier for operators to manage the cable in a confined space and reducing the interference of the cable on the operation process.

[0033] In a preferred embodiment, the magnetic attraction component 5 is a ring-shaped permanent magnet. The ring-shaped permanent magnet is fixed inside the sleeve body 1 by pressing or bonding. The ring-shaped permanent magnet can provide uniform and strong magnetic attraction force, which can attract probes or locking elements from all directions, ensuring the stability of the attraction. The pressing or bonding method is simple and reliable, which can ensure the positional stability of the ring-shaped permanent magnet inside the sleeve body 1. It is not easy to loosen during long-term use and frequent operation, and can continuously play a stable attraction function.

[0034] In a preferred embodiment, the adsorption end face of the annular permanent magnet is coplanar with the bottom end face of the working interface 3 or is recessed from the working interface 3 toward the driving interface 2. This arrangement allows the annular permanent magnet to directly and effectively adsorb the probe or locking element located at the working interface 3, ensuring maximum adsorption force. When the adsorption end face is recessed, while ensuring the adsorption function, it can also avoid wear or magnetic interference to other components that may be caused by direct contact between the permanent magnet and external components during operation, thus extending the service life of the annular permanent magnet and improving the stability of the entire operation.

[0035] In a preferred embodiment, the sleeve body 1 is made of non-magnetic metal material or high-strength engineering plastic. The sleeve body 1 made of non-magnetic metal material or high-strength engineering plastic has two advantages: first, it can avoid the sleeve body 1 from interfering with the magnetic field of the magnetic attraction component 5, ensuring that the magnetic attraction component 5 can perform its adsorption function normally; second, non-magnetic metal materials generally have good strength and durability, can withstand various forces during the assembly process, and are not easily damaged, while high-strength engineering plastics can reduce the weight of the sleeve, making it convenient for operators to operate in confined spaces for a long time and reducing the workload.

[0036] Example 2

[0037] This embodiment also provides a probe assembly tool assembly, including: a magnetic assembly sleeve as in Embodiment 1; and a drive handle. One end of the drive handle has a connector that matches the drive interface 2. The matching design between the drive handle and the magnetic assembly sleeve makes the entire tool assembly form a complete and easy-to-use operating system. The drive handle provides the operator with a better grip and force application method. Through the matching connection between the connector and the drive interface 2, the force applied by the operator can be transmitted to the sleeve body 1 more smoothly, further improving the convenience and efficiency of probe assembly work, and improving the overall performance and operability of the tool.

[0038] Example 3

[0039] The following is a method of using a magnetic charging sleeve for a wire harness probe in a confined space, as provided by this utility model.

[0040] First, place the probe or its locking element into the working interface 3 of the sleeve body 1, ensuring the extension cable exits from the axial groove 4. Next, the probe or locking element is attracted and secured by the annular permanent magnet of the magnetic attraction assembly 5, preventing it from falling off during operation. Then, connect the connector of the drive handle to the drive interface 2 of the sleeve body 1. The operator holds the drive handle and inserts the sleeve body 1, along with the probe or locking element, into the installation position within the confined space. Afterward, rotating the drive handle causes the sleeve body 1 to rotate via the drive interface 2. The engagement of the working interface 3 with the probe or locking element transmits torque, completing the probe installation or removal operation. Throughout the process, the axial groove 4 continuously provides a path for the extension cable to exit, preventing tangling or damage, while the magnetic attraction assembly 5 maintains a stable attraction to the probe or locking element, ensuring smooth operation.

[0041] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
