Description

Technical Field

[0001] This utility model relates to a support device, and more particularly to a support device for laying optical cables. Background Technology

[0002] Optical cable laying refers to the process of laying and installing optical cables along a surveyed route to form an optical cable line. Depending on the application, it can be divided into several laying methods, including overhead, underground (duct and direct burial), underwater, wall, and tunnel laying. Choosing the appropriate optical cable laying method is crucial for ensuring the transmission quality, reliability, and ease of construction and maintenance. This is especially important when high-altitude optical cable laying is required.

[0003] For example, Chinese Patent Publication No. CN218158467U discloses a support device for optical cable laying, including a base and an optical cable support mechanism. The base has a cylinder at its upper end, and a lead screw is rotatably connected to the inside of the cylinder through a bearing. A sliding plate is slidably connected to the inner wall of the cylinder, and the threaded hole inside the sliding plate is threadedly connected to the lead screw. A groove is opened on the outer arc surface of the cylinder, and the protruding part of the sliding plate is slidably connected to the groove. The optical cable support mechanism is set at the upper end of the sliding plate. A base plate is set at the bottom end of the base, and a control switch is set at the upper end of the base plate. The input end of the control switch is electrically connected to an external power source. This support device for optical cable laying can clamp optical cables or optical cable groups of different diameters and can automatically adjust the height of the optical cable. It replaces the manual lifting process in optical cable laying, is simple to operate, saves time and effort, and has a wide range of applications.

[0004] The aforementioned existing support device for optical cable laying has some problems. First, optical cable laying is mostly carried out in the field, and the ground is usually unpaved. The uneven ground makes it difficult to place the device horizontally and stably on the ground. Second, the device is an integrated unit, which is large in size and not convenient to move or relocate in the field. Utility Model Content

[0005] The purpose of this utility model is to provide an optical cable laying support device to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic cable laying support device, comprising a base, a limiting storage groove formed on the front and back of the base, an extended support arm slidably installed in the limiting storage groove, a threaded sleeve embedded in the extended support arm, a threaded support rod threadedly installed in the threaded sleeve, a ball head fixedly connected to the lower end of the threaded support rod, a support rod connected to the top of the base, the support rod comprising several segmented support columns and a top plate, connecting flanges fixedly connected to the upper and lower ends of the segmented support columns, connecting bolts provided in the connecting flanges, a pulley directly rotatably installed under the top plate, a limiting slide groove formed on the front of the support rod, a limiting slider slidably installed in the limiting slide groove, a slider fixedly connected to the front of the limiting slider, an arc-shaped lower support block fixedly connected to the front of the slider, an arc-shaped upper support block hinged above the arc-shaped lower support block and located on the front of the slider, a lifting lug fixedly connected to the top of the slider, a pull rope fixedly connected inside the lifting lug, the pull rope cooperating with the pulley.

[0007] Preferably, a support wheel is fixedly connected to the bottom of the base near the four corner edges, a threaded fixing hole is opened on the top of the base, and a winding post is fixedly connected to the top of the base near one side edge.

[0008] Preferably, limiters are fixedly connected to both sides of the base, and a limit groove is formed in the limiter. A limit pin is slidably installed in the limit groove. Two limit holes are formed on the side of the extended support arm. The limit holes and the limit pin cooperate with each other. A knob is fixedly connected to the upper end of the threaded support rod.

[0009] Preferably, a spring washer is fixedly connected to the limiting pin, a return spring is sleeved on the limiting pin, and a pull ring is fixedly connected to the upper end of the limiting pin.

[0010] Preferably, the top plate has a connecting through hole, which is matched with a connecting bolt.

[0011] Preferably, both the arc-shaped upper support block and the arc-shaped lower support block are provided with fixing through holes, and fixing bolts are installed in the fixing through holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By extending the support arm to both sides, and then rotating the threaded support rod to move the ball head down, the ball head touches the ground and supports the device. First, extending the support arm to both sides increases the stability torque of the device, reduces the overturning force, and reduces the possibility of tipping over. The height of the ball head can be adjusted by rotating the threaded support rod alone, which can adjust the level of the base, so that the base can be used on inclined or uneven ground.

[0014] 2. The devices are assembled together using bolts, and the splicing method allows the devices to be disassembled into smaller parts, facilitating early transfer and transportation.

[0015] 3. Use a rope to pull the slider upwards, thereby raising the optical cable to a suitable height. This method is done manually, avoiding the need for electricity and the need for additional energy supply equipment such as generators in the field. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-5This utility model provides a technical solution: a fiber optic cable laying support device, including a base 1. The base 1 has limiting and receiving grooves 104 on its front and rear sides. An extended support arm 2 is slidably installed within the limiting and receiving grooves 104. A threaded sleeve 201 is embedded within the extended support arm 2. A threaded support rod 202 is threadedly installed within the threaded sleeve 201. A ball head 204 is fixedly connected to the lower end of the threaded support rod 202. A support rod 4 is connected to the top of the base 1. The support rod 4 includes several segmented support columns 401 and a top plate 404. Connecting flanges are fixedly connected to the upper and lower ends of each segmented support column 401. 402, a connecting bolt 407 is provided inside the connecting flange 402, a pulley 406 is directly rotated and installed under the top plate 404, a limit groove 403 is opened on the front of the support rod 4, a limit slider 505 is slidably installed in the limit groove 403, a slider 5 is fixedly connected to the front of the limit slider 505, an arc-shaped lower support block 501 is fixedly connected to the front of the slider 5, an arc-shaped upper support block 502 is hinged above the arc-shaped lower support block 501 and located on the front of the slider 5, a lifting lug 506 is fixedly connected to the top of the slider 5, a pull rope 6 is fixedly connected inside the lifting lug 506, and the pull rope 6 cooperates with the pulley 406.

[0024] In this implementation scheme, a support rod 4, composed of multiple segmented support columns 401 connected to the top plate 404, is fixed together by connecting bolts 407 and connecting flanges 402. This splicing method allows the device to be disassembled into smaller parts, facilitating initial transfer and transportation. Simultaneously, an extension support arm 2 is inserted into the limiting storage groove 104. After the device is assembled, the extension support arm 2 needs to extend from the limiting storage groove 104, expanding to both sides. A threaded support rod 202 is threadedly engaged with a threaded sleeve 201. Rotating the threaded support rod 202 causes the ball head 204 to move downwards. After the ball head 204 touches the ground, it replaces the support wheel 103 in supporting the base 1. The position of the ball head 204 can be adjusted individually according to the ground conditions to ensure the base 1 is level. The levelness of the base 1 can be visually checked, or it can be adjusted in conjunction with other methods. A leveling device, such as a bubble level, is used to check if the base 1 is level. The extended support arm 2 expands to both sides, increasing the stability torque of the device, reducing the overturning force, and lowering the possibility of tipping over. The ball head 204 is used to support the base 1 in contact with the ground. The height of the ball head 204 can be adjusted by rotating the threaded support rod 202, which can adjust the level of the base 1, allowing the base 1 to be used on inclined or uneven ground. The optical cable is placed on the arc-shaped lower support block 501, and then the arc-shaped upper support block 502 is rotated to cover the arc-shaped lower support block 501, clamping the optical cable between the arc-shaped lower support block 501 and the arc-shaped upper support block 502. The pull rope 6 passes through the pulley 406 and is connected to the lifting lug 506. Pulling the pull rope 6 can move the lifting lug 506, which can move the slider 5, which can move the arc-shaped lower support block 501 and the arc-shaped upper support block 502, thereby moving the optical cable to support it.

[0025] To achieve the purpose of fixing the extended support arm 2, the device adopts the following technical solution: support wheels 103 are fixedly connected to the four corner edges of the base 1, threaded fixing holes 102 are opened on the base 1, winding piles 101 are fixedly connected to the base 1 near one side edge, limiters 3 are fixedly connected to both sides of the base 1, limit grooves 301 are opened in the limiters 3, and limit pins 302 are slidably installed in the limit grooves 301. Two limit holes 205 are opened on the side of the extended support arm 2, and the limit holes 205 cooperate with the limit pins 302. A knob 203 is fixedly connected to the upper end of the threaded support rod 202, a spring washer 303 is fixedly connected to the limit pin 302, a return spring 304 is sleeved on the limit pin 302, and a pull ring 305 is fixedly connected to the upper end of the limit pin 302.

[0026] The support wheel 103 allows the base 1 to slide on the ground. The threaded fixing hole 102, in conjunction with the bolt, can fix the support rod 4 onto the base 1. The winding post 101 is used to wind the slider 5 and fix both ends of the slider 5. The return spring 304 can provide a certain pushing force to the spring pad 303. The spring pad 303, under the pushing force, can drive the limiting pin 302 to insert into the limiting hole 205, thereby fixing the extended support arm 2 inside the limiting storage groove 104. There are two limiting holes 205. When the limiting pin 302 is inserted into the two limiting holes 205 respectively, it corresponds to the two states of the extended support arm 2 being located inside the limiting storage groove 104 and the extended support arm 2 being extended. The pull ring 305 can drive the limiting pin 302 to move out of the limiting hole 205.

[0027] In order to fix the top plate 404 to the upper end of the segmented support column 401, the device adopts the following technical solution: a connecting through hole 405 is opened in the top plate 404, the connecting through hole 405 cooperates with the connecting bolt 407, and a fixing through hole 503 is opened in both the arc-shaped upper support block 502 and the arc-shaped lower support block 501, and a fixing bolt 504 is installed in the fixing through hole 503.

[0028] By connecting the through hole 405 and the connecting bolt 407, the connecting bolt 407 is passed through the connecting through hole 405 and the connecting flange 402, and the nut is screwed on to fix the top plate 404 to the upper end of the segmented support column 401. When the arc-shaped upper support block 502 and the arc-shaped lower support block 501 are attached together, the fixing bolt 504 is passed through the two fixing through holes 503 and the nut is screwed on to fix the arc-shaped lower support block 501 and the arc-shaped upper support block 502 together.

[0029] The working principle and usage process of this utility model are as follows: When using the device, it needs to be placed in a suitable position and assembled. Then, the pull ring 305 drives the limiting pin 302 out of the limiting hole 205, releasing the restriction on the extension support arm 2. At this time, the extension support arm 2 can be pulled out, allowing it to extend to both sides. Then, the knob 203 drives the threaded support rod 202 to rotate. The rotation of the threaded support rod 202 causes the ball head 204 to move downwards, gradually touching the ground and supporting the base 1. Visual inspection or a leveling device can be used to check if the base 1 is level. The threaded support rod can be rotated individually. The support rod 202 drives the ball head 204 to move, adjusting the base 1 to a horizontal state. The optical cable is placed on the arc-shaped lower support block 501, and then the arc-shaped upper support block 502 is rotated to cover the arc-shaped lower support block 501. The fixing bolt 504 and the fixing through hole 503 are used to fix the arc-shaped lower support block 501 and the arc-shaped upper support block 502 together, clamping and fixing the optical cable. Then, the pull rope 6 is pulled to drive the slider 5 to move. The movement of the slider 5 can drive the arc-shaped lower support block 501 and the arc-shaped upper support block 502 to move, thereby driving the optical cable to move. When the optical cable moves to a suitable height, the end of the pull rope 6 is wound and tied to the winding post 101.
