Description

Technical Field

[0001] This utility model belongs to the field of electrical engineering technology, specifically relating to a cable positioning and installation device for electrical engineering and automation. Background Technology

[0002] Cables, as a key component of electrical engineering and its automation systems, are widely used in power transmission, signal control, and communication. Depending on their application, cables can be categorized into power cables, control cables, and communication cables. With continuous advancements in materials science and manufacturing technology, the performance and service life of cables have been significantly improved, better meeting the demands of modern electrical engineering for efficient, stable, and safe operation.

[0003] However, cable installation and securing still face numerous challenges in traditional high-altitude electrical engineering. Due to the lack of efficient and flexible positioning and securing devices, cables are prone to instability, swaying, or misalignment during installation, especially during long-distance laying. These problems are particularly prominent, and loose or misaligned cables not only affect the normal operation of the electrical system but may also cause safety hazards and reduce the system's reliability and stability.

[0004] Most existing cable fixing devices are designed with fixed dimensions, making it difficult to adapt to cables of different diameters or complex laying environments. Furthermore, traditional devices are cumbersome and inflexible during installation and adjustment, resulting in low construction efficiency. Therefore, there is an urgent need to design an adjustable cable positioning and installation device to adapt to different cable specifications and laying conditions, improving the flexibility and stability of cable installation, thereby ensuring the safe operation of electrical systems.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cable positioning and installation device for electrical engineering and automation. It is mainly used to solve the problems that cables are prone to unstable position, shaking or displacement during installation, which affects the normal operation of electrical systems and poses safety hazards. It also addresses the problems that existing fixing devices are mostly fixed in size and cannot adapt to cables of different diameters and complex laying environments, and that installation and adjustment operations are cumbersome and construction efficiency is low. This invention, through the coordinated cooperation of an adjustable clamping and limiting mechanism and a telescopic connection mechanism, can adapt to cables of different diameters and complex laying environments, improving the flexibility and stability of cable installation.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] This utility model provides a cable positioning and installation device for electrical engineering and automation, including a plate-shaped support member. The support member is provided with an adjustable clamping and limiting mechanism for fixing cables of different diameters. At the same time, telescopic connecting mechanisms are symmetrically hinged at both ends of the support member with the adjustable clamping and limiting mechanism as the center. The end of the telescopic connecting mechanism away from the support member is fixed to the mounting base for adjusting the installation height of the cable.

[0009] Furthermore, the adjustable clamping and limiting mechanism includes a U-shaped member hinged to the carrier member, and an elastic seat assembly is provided on the carrier member between the two vertical sections of the U-shaped member. The elastic seat assembly includes a first arc-shaped clamping plate located at its top.

[0010] Among them, a second arc-shaped clamping plate that cooperates with the first arc-shaped clamping plate is movably installed on the two vertical sections, and the outer walls of the two vertical sections are symmetrically provided with external threads. An internal threaded cylinder is threadedly connected to each external thread. A first elastic element is provided between each internal threaded cylinder and the second arc-shaped clamping plate. By rotating the internal threaded cylinder, it is used to squeeze the second arc-shaped clamping plate and the first arc-shaped clamping plate to form a ring structure to clamp the cable.

[0011] Furthermore, the outer wall of the internally threaded cylinder is provided with anti-slip texture.

[0012] Furthermore, an open gasket is provided between the internally threaded cylinder and the first elastic element.

[0013] Furthermore, a bearing is provided at the bottom of the internally threaded cylinder, and the inner ring of the bearing is fixedly connected to the outer wall of the internally threaded cylinder. The end of the first elastic element away from the second arc-shaped clamp is stuck between the inner and outer rings of the bearing.

[0014] Furthermore, the inner surfaces of both the first and second arc-shaped clamps are provided with a rubber layer.

[0015] Furthermore, the elastic seat assembly includes a support column fixedly connected to the bearing member, a cylindrical structure slidably disposed on the outside of the support column in the vertical direction, the first arc-shaped clamping plate is fixedly disposed on the top of the cylindrical structure, and a second elastic member is disposed between the cylindrical structure and the support column.

[0016] Furthermore, a number of limiting blocks are evenly distributed around the bottom inner wall of the cylindrical structure, and each limiting block cooperates with the outer edge of the top of the support column to form a mechanical limit.

[0017] Furthermore, the first elastic element and the second elastic element are springs or rubber.

[0018] Furthermore, the telescopic connection mechanism includes a first connector and a second connector movably sleeved outside the first connector. The first connector is hinged to a hinge seat fixedly disposed at the end of the bearing member, and the horizontally extending section of the second connector is connected to the mounting base by fasteners.

[0019] The first connector has multiple first holes equidistantly spaced along its length, and the second connector has at least two second holes. The center distance between adjacent second holes is the same as the center distance between adjacent first holes. After the relative position of the second connector is adjusted to that of the first connector, it is locked by passing bolts through the second holes and the first holes.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The cable positioning and installation device provided by this utility model mainly consists of a bearing component, an adjustable clamping and limiting mechanism, and a telescopic connection mechanism. Through the coordinated operation of the adjustable clamping and limiting mechanism and the telescopic connection mechanism, it can adapt to cables of different diameters and complex laying environments, solving the problem that traditional fixing devices are difficult to adapt to diverse needs due to their fixed size design. In particular, the adjustable clamping and limiting mechanism, by rotating the internal threaded cylinder, makes the second arc-shaped clamping plate and the first arc-shaped clamping plate form an embracing structure, which can quickly and firmly clamp cables of different diameter specifications. In addition, the telescopic connection mechanism is symmetrically arranged on both sides of the adjustable clamping and limiting mechanism and is fixedly connected to the installation base (such as building structure, support frame, or fixed point in ceiling, etc.), which can flexibly adjust the installation height of the cable, further improving the applicability and installation efficiency of the cable positioning and installation device. The overall structure of this utility model is simple and reliable, easy to operate, significantly improves the stability and construction efficiency of cable installation, and effectively avoids safety hazards caused by cable loosening or displacement.

[0022] 2. The cable positioning and installation device provided by this utility model has an upper arc-shaped clamping plate (i.e., the second arc-shaped clamping plate) movably mounted on two vertical sections of a U-shaped component. Both vertical sections are provided with external threads. The upper part of the arc-shaped clamping plate is provided with an internally threaded cylinder screwed to the external threads. A spring is provided between the internally threaded cylinder and the arc-shaped clamping plate. The key feature is that a bearing is provided at the bottom of the internally threaded cylinder. The inner ring of the bearing is fixedly connected to the outer wall of the internally threaded cylinder, and the top of the spring is engaged with the rotating shaft between the inner and outer rings of the bearing. Through this arrangement, when the internally threaded cylinder rotates, the spring only bears the downward pressure applied by the internally threaded cylinder and will not rotate with the internally threaded cylinder, thereby reducing the frictional force when rotating the threaded cylinder and effectively extending the service life of the adjustable clamping and limiting mechanism.

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses consistent with some aspects of this invention as detailed in the appended claims.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] Please see Figures 1-4 The present invention provides a cable positioning and installation device for electrical engineering and automation, comprising a plate-shaped support member 1, on which an adjustable clamping and limiting mechanism 2 for fixing cables of different diameters is provided. At the same time, with the adjustable clamping and limiting mechanism 2 as the center, telescopic connecting mechanisms 3 are symmetrically hinged at both ends of the support member 1. The end of the telescopic connecting mechanism 3 away from the support member 1 is fixed to the mounting base (e.g., a building structure, support frame, or a fixed point in the ceiling) for adjusting the installation height of the cable.

[0037] Specifically, in this embodiment of the invention, the support member 1 is made of a metal material, such as aluminum alloy, and its cross-section has an inverted V-shape. This structural design ensures that the support member 1 has sufficient strength to stably support the weight of the cable and related components. Furthermore, the inverted V-shaped groove provides a platform for installing the adjustable clamping and limiting mechanism 2, while the protruding portions at both ends of the inverted V-shape are used to install the telescopic connection mechanism 3. This arrangement fully utilizes the spatial layout of the support member 1, contributing to the compactness of the overall structure.

[0038] In this embodiment of the utility model, the structural design of the adjustable clamping and limiting mechanism 2 is as follows: Figure 1 , 2 As shown in Figure 3, it includes a U-shaped member 21 with the opening direction facing downward. The bottom of the two vertical sections 211 of the U-shaped member 21 is hinged to the hinge seat fixedly installed in the groove of the bearing member 1. This allows the U-shaped member 21 to rotate back and forth relative to the bearing member 1 within a certain angle range to adapt to cables with different laying angles.

[0039] Among them, on the bearing member 1, between the two vertical segments 211 of the U-shaped member 21, there is a such Figure 3The elastic seat assembly 22 shown includes a support column 222 fixedly connected to the carrier 1. The support column 222 can be fixed to the carrier 1 by welding or bolting to ensure that it will not loosen during long-term use. A cylindrical structure 223 is slidably provided on the outside of the support column 222 in the vertical direction. The specific sliding structure of the cylindrical structure 223 on the outside of the support column 222 is not limited in this utility model. For example, a guide strip can be provided on the outer wall of the support column 222, and a guide groove that cooperates with the guide strip can be opened on the inner wall of the cylindrical structure 223 to ensure that the cylindrical structure 223 slides smoothly and steadily on the support column 222, avoiding shaking or jamming. Furthermore, a first arc-shaped clamping plate 221 is fixedly installed at the top of the cylindrical structure 223. The connection between the first arc-shaped clamping plate 221 and the cylindrical structure 223 can be ensured by welding or integral molding. A second elastic element 224 is installed in the accommodating cavity formed by the cylindrical structure 223 and the support column 222. The second elastic element 224 is preferably a spring. In actual installation, one end of the spring is fixed to the top of the support column 222, and the other end is fixedly connected to the inner top surface of the cylindrical structure 223, thereby positioning the spring and preventing it from shifting during operation. When the cable is placed on the first arc-shaped clamping plate 221, the second elastic element 224 can play a role in buffering and self-adjusting to better fit the surface of cables of different diameters.

[0040] Preferably, in this embodiment of the present invention, two limiting blocks 2231 are symmetrically arranged around the bottom inner wall of the cylindrical structure 223. Each limiting block 2231 cooperates with the outer edge of the top of the support column 222 to form a mechanical limit, preventing the cylindrical structure 223 from detaching from the support column 222 under the action of the elastic force of the second elastic element 224.

[0041] Furthermore, in this embodiment of the invention, a second arc-shaped clamping plate 23 is movably installed on the two vertical sections 211. The second arc-shaped clamping plate 23 is located above the first arc-shaped clamping plate 221. Through their mutual cooperation, the two achieve stable clamping of the cable. Specifically, external threads 2111 are symmetrically provided on the outer walls of the two vertical sections 211. Each external thread 2111 is threadedly connected to an internal threaded cylinder 24. The outer wall of the internal threaded cylinder 24 is provided with anti-slip texture 241. In actual operation, the operator can directly hold the internal threaded cylinder 24 by hand and rotate it. The anti-slip texture 241 can increase the friction between the hand and the internal threaded cylinder 24, making the operation more labor-saving and convenient. Each internally threaded cylinder 24 is provided with a first elastic element 25 between itself and the second arc-shaped clamping plate 23. This first elastic element 25 is preferably a spring, which possesses excellent elastic deformation capability. This characteristic allows it to effectively buffer and adaptively adjust under different working conditions. When the cable is subjected to external impact or slight shaking, the spring can absorb and disperse energy, reducing damage to the cable while ensuring stable clamping force. Furthermore, to further optimize the structure, an open gasket can be provided between the internally threaded cylinder 24 and the first elastic element 25. The open gasket can protect the spring and distribute force evenly. Based on the above configuration, the adjustable clamping and limiting mechanism 2 has a flexible adjustment function. The operator only needs to rotate the internally threaded cylinder 24 to compress the second arc-shaped clamping plate 23, forming a ring structure with the first arc-shaped clamping plate 221, thereby achieving cable clamping. Moreover, this mechanism can flexibly adjust the tightness of the ring according to different cable diameters, ensuring reliable clamping effects for various cable specifications, and possessing strong versatility and practicality.

[0042] Preferably, in this embodiment of the present invention, the inner surfaces of the first arc-shaped clamping plate 221 and the second arc-shaped clamping plate 23 are both provided with a rubber layer. The rubber layer has good flexibility and friction, so when clamping the cable, it can avoid damage to the cable sheath and increase the friction between the cable and the cable, making the clamping more stable.

[0043] In this embodiment of the utility model, the structural design of the telescopic connection mechanism 3 is as follows: Figure 1 , 4As shown, the system includes a first connecting member 31 and a second connecting member 32 movably sleeved outside the first connecting member 31. The first connecting member 31 is hinged to a hinge seat 11 fixedly disposed at the end of the bearing member 1. The hinge seat 11 is fixed to the end of the bearing member 1 by welding or bolt connection. The first connecting member 31 and the hinge seat 11 are connected by a hinge component such as a pin, ensuring that the first connecting member 31 can rotate flexibly relative to the hinge seat 11. The horizontally extending section of the second connecting member 32 is fixedly connected to the mounting base by fasteners (such as bolts, nuts, etc.). In actual installation, an elongated hole can be opened on the horizontally extending section of the second connecting member 32, so that the position of the fixing point can be flexibly adjusted according to the actual installation position when fixing it to the mounting base.

[0044] The first connector 31 has multiple first holes 311 equidistantly spaced along its length, and the second connector 32 has at least two second holes 321. The center distance between adjacent second holes 321 is the same as the center distance between adjacent first holes 311. When adjusting the cable installation height, the second connector 32 is first slid onto the first connector 31 to a suitable position, and then the bolt is passed through the second hole 321 and the corresponding first hole 311 and locked, thereby realizing flexible adjustment of the cable installation height.

[0045] The operation process of the cable positioning and installation device provided in this embodiment of the utility model is as follows:

[0046] First, based on the cable's laying location, the carrier 1 is adjusted to a suitable height using the telescopic connection mechanism 3, and the first connector 31 and the second connector 32 are fixed with bolts. Then, the cable is placed on the first arc-shaped clamping plate 221 of the adjustable clamping and limiting mechanism 2. According to the cable's diameter, the internal threaded cylinder 24 is rotated, causing the second arc-shaped clamping plate 23 to gradually approach the first arc-shaped clamping plate 221 until the second arc-shaped clamping plate 23 and the first arc-shaped clamping plate 221 tightly encircle and clamp the cable. At this time, the first elastic element 25 and the second elastic element 224 are both in a compressed state, which can adaptively buffer and firmly clamp the cable, ensuring that the cable's position is stable during installation and that there will be no shaking or displacement. This effectively improves the flexibility and stability of cable installation and ensures the safe operation of the electrical system.

[0047] Example 2

[0048] Based on Embodiment 1, this embodiment further optimizes the structure of the adjustable clamping and limiting mechanism 2. Specifically, a bearing 26 is added to the bottom of the internal threaded cylinder 24. The inner ring of the bearing 26 is fixedly connected to the outer wall of the internal threaded cylinder 24 by means of interference fit, welding, etc. The end of the first elastic element 25 away from the second arc-shaped clamping plate 23 is stuck between the inner and outer rings of the bearing 26. With this structural design, when the operator rotates the internal threaded cylinder 24, due to the action of the bearing 26, the first elastic element 25 only bears the downward pressure applied by the internal threaded cylinder 24 and will not rotate with the internal threaded cylinder 24. This feature effectively reduces the friction generated when rotating the threaded cylinder 24, thereby reducing the wear of the spring and extending the service life of the adjustable clamping and limiting mechanism 2, so that it can maintain stable and reliable performance during long-term use.

[0049] To further enhance the reliability of this structure, considering that the first elastic element 25 may cause wear to the balls between the inner and outer rings of the bearing 26 when subjected to the compressive force applied by the internal threaded cylinder 24, a washer can be placed between the balls and the first elastic element 25. The washer can act as a buffer and isolate, reducing direct contact and friction between the first elastic element 25 and the balls, thereby better protecting the internal structure of the bearing 26 and ensuring that the adjustable clamping and limiting mechanism 2 is always in good working condition.

[0050] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.

[0051] It should be understood that this utility model is not limited to the content already described above, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
