Description

Technical Field

[0001] This application relates to the field of optical cable laying technology, and in particular to an anti-slip lifting device for optical cable laying. Background Technology

[0002] With the rapid development of smart grids and the Internet of Things, society's demand for broadband is constantly increasing. As the foundation of communication networks, fiber optic cables are being continuously deployed as networks expand. The widespread application of fiber optic cables has greatly improved the speed and stability of information transmission, powerfully promoting the digital transformation and intelligent development of various industries, and driving the informatization process of the entire society. In today's digital age, people are highly dependent on high-speed and stable network communication. Whether it's daily social entertainment, business office work, industrial production, or telemedicine, all fields rely on communication networks built with fiber optic cables.

[0003] In the past, to cope with various complex terrains and environmental conditions, the laying of overhead optical cables typically involved manual pulling and simple pulley systems to lift the cables. When encountering excessively large spans or deep sags, workers would slowly pull the cable manually, using ropes and simple pulley structures to change the direction of force and attempt to lift it smoothly. Additionally, fixed supports were used to stabilize the cable and reduce swaying during lifting. However, these operations often require a significant manpower investment and demand extensive experience and high skill levels from the workers. In long-distance optical cable laying projects, this method is not only inefficient but also makes it difficult to guarantee consistent construction quality.

[0004] Existing technologies have significant shortcomings when dealing with the laying of overhead optical cables with excessively large spans or deep sags. During the cable lifting process, the cable often slips severely in the middle of the span or near the lowest point of the sag. This results in uneven stress distribution on the cable, leading to insufficient ground clearance and affecting traffic for vehicles and pedestrians. More seriously, it can directly cause cable deformation, core breakage, and other accidents, posing a significant threat to the normal use and maintenance of the optical cable. Utility Model Content

[0005] To avoid problems such as severe slippage, core breakage, and deformation of optical cables, this application provides an anti-slip lifting device for optical cable laying.

[0006] The anti-slip lifting device for optical cable laying provided in this application adopts the following technical solution:

[0007] An anti-slip lifting device for optical cable laying includes a support plate and a support beam. Positioning structures are installed at both ends of the support plate to fix it to a stranded cable. The support beam is connected to the support plate via a lifting structure. First clamping members are installed at both ends of the support beam along its length. A second clamping member is correspondingly provided on the lower surface of the support plate. The first clamping member includes a first clamping rod and a clamping pulley. One end of the first clamping rod is installed on the support beam, and the clamping pulley is installed at the end of the first clamping rod opposite to the support beam. A buffer layer is provided on the inner surface of the clamping pulley. The second clamping member has the same structure as the first clamping member.

[0008] By adopting the above technical solution, the positioning structure can fix the support plate on the cable, the lifting structure allows the support beam to move relative to the support plate, the first clamping member and the second clamping member can clamp the optical cable, and the buffer layer can reduce damage to the optical cable, thereby avoiding problems such as uneven force points, insufficient distance to the ground, and optical cable deformation and core breakage caused by severe slippage when lifting the optical cable.

[0009] In one specific implementation scheme, the positioning structure is configured as a hook, and there are two hooks. One end of each hook is hinged to both sides of the support plate along the length direction, and the other end of each hook is inclined upward and facing the other side. The two hooks are staggered.

[0010] By adopting the above technical solution and using hooks as a positioning structure, the support plate can be easily fixed on the cable. One end of each hook is hinged to both sides of the support plate along its length, and the other end is tilted upward and facing the other side, and they are staggered. This allows the support plate to be firmly installed on the cable, ensuring the stability of the anti-slip lifting device during operation.

[0011] In one specific implementation scheme, the lifting mechanism is provided in two sets and is symmetrically installed on both sides of the support plate along its length. The lifting mechanism includes a drive motor, a drum and a guide cable. The drum is rotatably connected to the support plate. The drive motor is installed on the support plate and its output shaft is fixedly connected to the drum. One end of the guide cable is fixed to the drum, and the other end is fixedly connected to the corresponding side of the support beam.

[0012] By adopting the above technical solution, two sets of lifting mechanisms are set up symmetrically installed on both sides of the support plate along its length. The drive motor drives the drum to rotate, so that the guide cable can drive the support beam to rise and fall stably relative to the support plate.

[0013] In one specific implementation, several guide cables are provided, and the several guide cables are evenly arranged along the length direction of the drum.

[0014] By adopting the above technical solution and using several guide cables evenly arranged along the length of the drum, the support beam can be subjected to more uniform force during the lifting process, thus better achieving the lifting effect on the optical cable.

[0015] In one specific implementation scheme, the support plate is rotatably connected to several guide wheels corresponding to several guide cables, and the guide cables pass through the guide wheels and are connected to the support beam.

[0016] By adopting the above technical solution, during the process of the drive motor driving the drum to rotate and causing the guide cable to pull the support beam up or down, the guide wheel can guide the guide cable, ensuring stable operation of the guide cable and avoiding deviation or jamming during the movement of the guide cable.

[0017] In one specific implementation scheme, a telescopic rod is installed between the lower surface of the support plate and the support beam, with one end of the telescopic rod fixedly connected to the lower surface of the support plate and the other end fixedly connected to the support beam.

[0018] By adopting the above technical solution, the relative position of the support beam and the support plate can be limited by the telescopic rod, making the lifting process of the support beam more stable. At the same time, the telescopic rod can play a protective role, preventing the optical cable from falling off the support beam.

[0019] In one specific implementation scheme, the support beam is rotatably connected to a guide wheel via a support rod on the side wall facing the support plate. Several guide wheels are provided, and the several guide wheels are evenly arranged along the length direction of the support beam.

[0020] By adopting the above technical solution, several guide wheels evenly distributed along the length of the side wall of the support beam facing the support plate are set. This can reduce the frictional resistance of the optical cable during the lifting process, make the optical cable move more smoothly during the lifting process, avoid uneven force and damage caused by excessive friction, and ensure the smooth laying of the optical cable.

[0021] In one specific implementation, the first clamping rod consists of a sleeve and a sliding rod. The sleeve is fixedly connected to the support beam, and the sliding rod is slidably connected inside the sleeve. A clamping pulley is installed at one end of the sliding sleeve. A buffer spring is installed inside the sleeve, and the two ends of the buffer spring are fixedly connected to the inner wall of the sleeve and the end of the sliding rod, respectively.

[0022] By adopting the above technical solution, the first clamping rod is composed of a sleeve and a sliding rod, and the sleeve is equipped with a buffer spring. The second clamping rod has the same structure as the first clamping rod, which enables the first clamping member and the second clamping member to provide a buffering effect when clamping the optical cable.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By fixing the support plate to the strand through the positioning structure, the device can be stabilized, reducing the problem of optical cable slippage caused by device displacement, and making the stress points of the optical cable more even.

[0025] 2. The first clamping member and the second clamping member can clamp the optical cable, and together with the buffer layer on the inner surface of the first V-shaped block, prevent the optical cable from slipping, avoid insufficient distance to the ground affecting traffic, and protect the optical cable from deformation and core breakage.

[0026] 3. The lifting structure allows for adjustment of the support beam height, facilitating the lifting of optical cables and improving construction efficiency and quality in situations with excessive span or deep sag. Attached Figure Description

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] This application discloses an anti-slip lifting device for optical cable laying.

[0032] like Figure 1As shown, the anti-slip lifting device for optical cable laying includes a support plate 1, a support beam 2, a positioning structure, a lifting structure 4, a first clamping member 5, and a second clamping member 6. The support plate 1 is fixed to the stranded cable by the positioning structure. The support beam 2 is connected to the support plate 1 by the lifting structure 4. The first clamping member 5 is installed at both ends of the support beam 2 along its length. The second clamping member 6 is set on the lower surface of the support plate 1 and corresponds to the first clamping member 5. This structure can effectively lift the optical cable against slippage, avoiding problems such as severe slippage, uneven stress points, and insufficient distance to the ground when encountering areas with excessive span or deep sag during overhead optical cable laying. This is because the positioning structure ensures the overall fixation of the device, the lifting structure 4 can adjust the height of the support beam 2, and the first clamping member 5 and the second clamping member 6 can firmly clamp the optical cable.

[0033] Specifically, the positioning structure includes hooks 3. Two hooks 3 are provided, with one end of each hook hinged to opposite sides of the support plate 1 along its length. Hooks 3 are typically made of metal, possessing a certain strength and toughness, and are roughly hook-shaped, a design that facilitates attachment to the cable. Hooks 3 can also be replaced with clips or other structures, which provide a more secure hold to the cable. The other ends of the two hooks 3 are angled upwards and towards the opposite side, with the two hooks 3 staggered. This arrangement makes the hooks 3 more stable when attached to the cable, preventing them from easily falling off. When it is necessary to fix the support plate 1 to the cable, simply hook the two hooks 3 onto the cable. Their staggered arrangement increases friction and stability, ensuring that the support plate 1 will not easily shake or slip.

[0034] The lifting structure 4 includes a drive motor 41, a drum 42, and a guide cable 43. The drive motor 41 is typically a stepper motor, which can precisely control the rotation angle and speed. A servo motor can also be used, offering superior precision and stability. The drive motor 41 is mounted on the support plate 1, and its output shaft is fixedly connected to the drum 42. When the drive motor 41 operates, it drives the drum 42 to rotate. The drum 42 is usually cylindrical with a smooth surface, facilitating the winding of the guide cable 43. It is rotatably connected to the support plate 1. The guide cable 43 is typically made of steel wire rope, which has high strength and wear resistance. Nylon rope can also be used, but its strength is relatively low. One end of the guide cable 43 is fixed to the drum 42, and the other end is fixedly connected to the corresponding side of the support beam 2. When the drum 42 rotates, it drives the guide cable 43 to wind or unwind, thereby achieving the lifting and lowering of the support beam 2.

[0035] The drum 42 is equipped with several guide cables 43, which are evenly distributed along its length. This arrangement makes the support beam 2 more stable during lifting and lowering because the multiple guide cables 43 work simultaneously, distributing the tension and reducing the stress on each individual guide cable 43. Additionally, several guide wheels 7 are rotatably connected to the support plate 1 corresponding to the guide cables 43, with the guide cables 43 passing through the guide wheels 7 and connecting to the support beam 2. The guide wheels 7 are typically circular with a smooth surface, usually made of metal or plastic. The function of the guide wheels 7 is to change the direction of the guide cables 43, making their movement smoother and reducing friction between the guide cables 43 and the support plate 1, thus extending the service life of the guide cables 43. The guide wheels 7 can also be replaced by rollers, which also provide guidance and reduce friction.

[0036] like Figure 2 As shown, the first clamping member 5 includes a first clamping rod 51 and a clamping pulley 52. ​​The first clamping rod 51 consists of a sleeve 511 and a sliding rod 512. The sleeve 511 is fixedly connected to the support beam 2. The sleeve 511 is generally a metal round tube with a hollow interior to accommodate the sliding rod 512 and the buffer spring 513. The sliding rod 512 is slidably connected inside the sleeve 511, and the clamping pulley 52 is installed at one end of the sleeve. The sliding rod 512 is usually a cylindrical metal rod with a smooth surface to allow for smooth sliding within the sleeve 511. A buffer spring 513 is installed inside the sleeve 511. The two ends of the buffer spring 513 are fixedly connected to the inner wall of the sleeve 511 and the end of the sliding rod 512, respectively. When the clamping pulley 52 is subjected to external pressure, the sliding rod 512 will slide within the sleeve 511 and compress the buffer spring 513, thus providing a buffering effect and preventing the optical cable from being damaged by excessive pressure. The surface of the clamping pulley 52 is provided with a buffer layer, which is generally made of rubber. It is soft and can increase the friction with the optical cable while protecting the optical cable from scratches. It can also be replaced with soft materials such as sponge.

[0037] The second clamping member 6 has the same structure as the first clamping member 5, and also includes a second clamping rod and a second V-shaped block. Their structure and function are similar to those of the first clamping member 5. They can cooperate with the first clamping member 5 to clamp the optical cable together and ensure that the optical cable will not slip during the lifting process.

[0038] A telescopic rod 8 is installed between the lower surface of the support plate 1 and the support beam 2. One end of the telescopic rod 8 is fixedly connected to the lower surface of the support plate 1, and the other end is fixedly connected to the support beam 2. The telescopic rod 8 is generally composed of multi-stage sleeves, which can play an auxiliary support and guiding role when the lifting structure 4 adjusts the height of the support beam 2, ensuring the stability of the support beam 2 during the lifting process.

[0039] A guide wheel 9 is rotatably connected to the side wall of the support beam 2 facing the support plate 1 via a support rod. Several guide wheels 9 are provided, and they are evenly distributed along the length of the support beam 2. The guide wheels 9 are usually circular with a smooth surface and are generally made of plastic or rubber. They can reduce the friction between the optical cable and the support beam 2, making the optical cable move more smoothly during lifting. Alternatively, ball bearings can be used to replace the guide wheels 9, which can further reduce friction.

[0040] The implementation principle of an anti-slip lifting device for optical cable laying according to an embodiment of this application is as follows: The anti-slip lifting device fixes the support plate 1 to the stranded cable through a positioning structure, ensuring the stability of the device. The drive motor 41 drives the drum 42 to rotate, and the support beam 2 is raised and lowered through the guide cable 43, thereby adjusting the height of the optical cable. The first clamping member 5 and the second clamping member 6 clamp the optical cable, wherein the buffer spring 513 of the first clamping rod 51 and the buffer layer of the clamping pulley 52 can protect the optical cable from damage and prevent the optical cable from slipping. The telescopic rod 8 provides auxiliary support and guidance, and the guide wheel 9 reduces the friction between the optical cable and the support beam 2. Compared with the prior art, it improves the efficiency and safety of optical cable lifting, avoids problems such as uneven force on the optical cable, deformation and core breakage, and greatly improves the quality of overhead optical cable laying construction.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
