Description

Technical Field

[0001] The utility model relates to the technical field of cable equipment, in particular to an optical cable laying device. Background Art

[0002] Optical cable is an integrated transmission medium that organically combines metal wires and optical fibers to transmit electrical energy and optical information simultaneously, along the same path, and in the same direction. The optical cable is covered by several layers of protective structure. The outer protective layer and insulating layer can prevent the surrounding environment from damaging the optical fiber.

[0003] However, due to the large size of existing cable reels, the optical cable laying equipment can only fix a single size. The cable reel is higher than the table top, which will cause the overall center of gravity to be higher, increasing the risk of the equipment tipping over. For cable reels of different diameters, the clamping height must also be adjusted accordingly, and the original positioning cable reel clamping components need to be disassembled and adjusted to the corresponding height. This process is relatively cumbersome, labor-intensive, and not convenient enough. Utility Model Content

[0004] Based on this, it is necessary to provide an optical cable laying device to address the problem of difficulty in adjusting the height of the cable drum, so that the height of the cable drum can be quickly adjusted according to the required height requirements.

[0005] An optical cable laying device includes a support platform, a first clamping plate and a second clamping plate are installed on opposite sides of the support platform, a U-shaped block is arranged between the first clamping plate and the second clamping plate, and slides are installed on the left and right sides of the U-shaped block. A threaded rod for driving the corresponding slide to move vertically is installed on each of the first clamping plate and the second clamping plate, and the threaded rod cooperates with the slide thread.

[0006] As a preferred solution, one end of each threaded rod that penetrates into the interior of the support platform is connected to a synchronous wheel, a steering gear and a motor that drives the input end of the steering gear to operate are installed inside the support platform, and the output end of the steering gear and multiple synchronous wheels are linked by a synchronous belt.

[0007] As a preferred solution, slide rails are vertically installed on two opposite sides of the first clamping plate and the second clamping plate, and each of the slide seats is provided with a slide groove for the slide rails to cooperate with, and the slide rails are inserted into the slide grooves.

[0008] As a preferred solution, vertical grooves are provided on two opposite side surfaces of the first clamping plate and the second clamping plate, and the threaded rod is rotatably connected in the vertical grooves.

[0009] As a preferred solution, support plates are provided on both sides of the bottom of the support platform, and the support plates are vertically fixedly connected to the support platform.

[0010] As a preferred solution, a rotatable bidirectional reciprocating screw is inserted between the two support platforms, and two relatively slidable sliders are installed on the bidirectional reciprocating screw, each slider is threadedly connected to the bidirectional reciprocating screw, a first connecting rod is hinged at the bottom of the slider, and a second connecting rod is hinged at the side of the support plate, and a rotatable roller is connected between the first connecting rod and the second connecting rod.

[0011] As a preferred solution, a hand wrench for driving the bidirectional reciprocating screw to rotate on the support plate is installed at the end of the bidirectional reciprocating screw, and the hand wrench is fixedly connected to the bidirectional reciprocating screw.

[0012] The utility model is beneficial in that:

[0013] 1. A structure that can adjust the lifting of the cable drum is designed. In this process, only four threaded rods need to be rotated to ensure that the slide and the U-shaped block accommodating the cable drum can move up and down between the first clamping plate and the second clamping plate. At the same time, in order to rotate multiple threaded rods synchronously, a linkage structure is designed. Subsequently, only the forward and reverse rotation of the motor in the linkage structure needs to be controlled to achieve the change of the height of the cable drum.

[0014] 2. The rollers are designed to be expandable or retractable. When the whole equipment needs to be moved, the rollers can be expanded and supported on the ground, and then the equipment can be pushed to move. On the contrary, when it is not needed, the rollers can be rotated and retracted to disconnect it from the ground, and the support plate can contact the ground to limit the continued movement of the equipment.

[0023] like Figure 1-Figure 4 As shown,

[0024] As an optional embodiment,

[0025] An optical cable laying device includes a support platform 1, on which a first clamping plate 2 and a second clamping plate 3 are installed on opposite sides, a U-shaped block 9 is arranged between the first clamping plate 2 and the second clamping plate 3, and slides 8 are installed on the left and right sides of the U-shaped block 9. A threaded rod 6 for driving the corresponding slide 8 to vertically move is installed on each of the first clamping plate 2 and the second clamping plate 3, and the threaded rod 6 is threadedly matched with the slide 8.

[0026] In the above structure, the cable drum is used to wind the cable, and in order to facilitate the placement of the cable drum, two front and rear U-shaped blocks 9 are designed; a first clamping plate 2 and two second clamping plates 3 are vertically installed on both sides of the top of the support platform 1, and a U-shaped block 9 is set between the first clamping plate 2 and the second clamping plate 3 on the same side. The central axis of the subsequent cable drum can be placed in the U-shaped block 9, and the front and rear U-shaped blocks 9 only need to be lifted and lowered between the first clamping plate 2 and the two second clamping plates 3. The structure of the U-shaped block 9 is as follows:

[0027] It is selected to install slides 8 on both sides of the left and right sides of the U-shaped block 9, and threaded rods 6 are installed on the first clamping plate 2 and the second clamping plate 3. The left and right threaded rods 6 correspond to the left and right slides 8, and the corresponding slides 8 are threadedly matched with the corresponding threaded rods 6. Subsequently, it is only necessary to rotate the four threaded rods 6 to drive the corresponding slides 8 and the U-shaped block 9 to rise and fall synchronously, and then the front and rear U-shaped blocks 9 move up and down between the first clamping plate 2 and the second clamping plate 3 to change the height change of the cable drum from the table top of the support platform 1. In this process, it is only necessary to rotate the four threaded rods 6 to achieve the final cable drum height adjustment. There is no need to disassemble parts throughout the process, which is more convenient to operate and reduces the workload of the staff.

[0028] Based on the first embodiment, Figure 3 As shown, in order to realize the synchronous rotation of the four threaded rods 6 and ensure that the front and rear U-shaped blocks 9 maintain the same height, the following linkage structure is designed to drive the four threaded rods 6 to rotate synchronously.

[0029] The linkage structure selects that each threaded rod 6 is connected to a synchronous wheel 10 at one end that penetrates into the support platform 1, and a steering gear 12 and a motor 13 that drives the input end of the steering gear 12 are installed inside the support platform 1. The output end of the steering gear 12 and multiple synchronous wheels 10 are linked through a synchronous belt 11.

[0030] The steering gear 12 has a Y-axis and a Z-axis, and a worm gear linkage is inside. The existing RL series right-angle commutator can be referred to. The output shaft of the motor 13 and the Y-axis of the steering gear 12 are installed with pulleys, and the two pulleys are driven by belts. A synchronous wheel 10 is installed on the Z-axis of the steering gear 12, and a synchronous wheel 10 is installed at the bottom of each of the four threaded rods 6. The five synchronous wheels 10 are connected by a synchronous belt 11. The subsequent motor 13 drives the Y-axis of the steering gear 12 to rotate, causing the Y-axis of the steering gear 12 to rotate, and then drives the synchronous wheels 10 connected to the four threaded rods 6 to rotate through the synchronous belt 11. The rotation of the threaded rod 6 drives the slide 8 to move up and down on the corresponding splint surface, and finally drives the U-shaped block 9 connected to the slide 8 to move up and down between the first splint 2 and the second splint 3.

[0031] Based on the first embodiment, Figure 2 As shown, in order to ensure better vertical displacement of the slide 8, a guiding structure is designed to ensure that the slide 8 does not tilt during the lifting process, and the following structure is designed:

[0032] That is, slide rails 7 are vertically installed on the opposite sides of the first splint 2 and the second splint 3, and each slide seat 8 is provided with a slide groove for the slide rail 7 to cooperate with. The slide rail 7 is inserted in the slide groove, and the slide seat 8 is driven to rise and fall under the cooperation of the threaded rod 6 and the thread of the slide seat 8. The slide rail 7 vertically penetrates the slide groove provided on the slide seat 8 to restrict the slide seat 8 from shaking back and forth and left and right.

[0033] Based on the first embodiment, Figure 2 As shown, in order to protect the threaded rod 6, vertical grooves 5 are selected to be opened on two opposite sides of the first clamping plate 2 and the second clamping plate 3, and the threaded rod 6 is rotatably connected in the vertical grooves 5.

[0034] In order to keep the support platform 1 at a certain height from the ground, support plates 14 are provided on both sides of the bottom of the support platform 1. The support plates 14 on the left and right sides raise the support platform 1 to reduce the contact between the support platform 1 and the ground.

[0035] Based on the first embodiment, Figure 4 As shown, in order to facilitate the transfer of the entire device, a liftable roller 19 is designed, and the specific lifting structure is as follows:

[0036] A rotatable bidirectional reciprocating screw 15 is inserted between the two support platforms 1, and two relatively slidable sliders 16 are installed on the bidirectional reciprocating screw 15. Each slider 16 is threadedly connected to the bidirectional reciprocating screw 15. A first connecting rod 17 is hinged at the bottom of the slider 16, and a second connecting rod 18 is hinged on the side of the support plate 14. A rotatable roller 19 is connected between the first connecting rod 17 and the second connecting rod 18.

[0037] Among them, the left and right sliders 16 are both threadedly connected with the two-way reciprocating screw rod 15. When the two-way reciprocating screw rod 15 is rotated, the left and right sliders 16 are close to or away from each other, so the left and right sliders 16 need to be installed one positive and one negative during installation. If it is necessary to shrink the roller 19, when the two-way reciprocating screw rod 15 is rotated clockwise, the left and right sliders 16 are close to each other, and the slider 16 drives the first connecting rod 17 and the second connecting rod 18 to move the roller 19 upward, and then the roller 19 is separated from the ground; similarly, if it is necessary to place the roller 19, when the two-way reciprocating screw rod 15 is rotated counterclockwise, the left and right sliders 16 are separated from each other, and the slider 16 drives the first connecting rod 17 and the second connecting rod 18 to move the roller 19 downward, and then the roller 19 contacts the ground and separates the support plate 14 from the ground, and then the support platform 1 can be pushed to move to the specified position; the distance from the connection between the second connecting rod 18 and the support plate 14 to the bottom surface of the support plate 14 is less than the length of the second connecting rod 18.

[0038] In order to facilitate the rotation of the bidirectional reciprocating screw 15 and better retract or expand the roller 19, a winch 20 for driving the bidirectional reciprocating screw 15 to rotate on the support plate 14 is installed at the end of the bidirectional reciprocating screw 15. The winch 20 is fixedly connected to the bidirectional reciprocating screw 15. Subsequently, the winch 20 only needs to be manually rotated forward and backward to synchronously drive the bidirectional reciprocating screw 15 to rotate on the support plate 14.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
