[0003] Traditional overhead cable laying methods often rely on relatively simple and crude tools and equipment. For example, in terms of cable transportation, there is a lack of effective transportation devices specifically for different types of cables. Due to the variety of cable types, differences in diameter and shape, traditional equipment is difficult to stably transport cables of different types, and cables are prone to deviation, which not only affects the laying efficiency, but may also cause wear on the cable sheath, thereby affecting the service life and safety of the cable.

[0004] In terms of cable laying height, the traditional method lacks a flexible height adjustment mechanism. In different working scenarios, such as crossing buildings of different heights and areas with large changes in topography, the cables need to be laid at a suitable height, but the existing equipment is difficult to quickly and accurately adjust to the required height, which brings many inconveniences to the cable laying work and limits the efficiency and adaptability of the laying work.

[0005] In addition, traditional cable laying equipment lacks convenient mobile devices, and it is difficult to quickly move to the appropriate position for operation at the construction site, which reduces overall work efficiency.

[0047] Please refer to the instruction manual Figure 1-Figure 5 , the utility model provides an overhead cable laying device:

[0048] Structural design of external fixed frame and lifting platform:

[0049] The main body of the device is an outer fixed frame 1, and a lifting platform 2 is installed inside the vertical long frame design. The lifting platform 2 can slide up and down in the frame. The design inside the frame allows the lifting platform 2 to move in the vertical direction, and there is a lifting platform lifting drive mechanism 3 connected to the outer fixed frame 1, which is used to control the vertical movement of the lifting platform 2 and then adjust the height of the cable conveying mechanism 4 set on its top.

[0050] Design of lifting drive mechanism:

[0051] The cable conveying mechanism 4 is used to handle the transmission of the cable. The lifting platform lifting drive mechanism 3 includes a first reduction motor 31, which controls the movement of the driving screw 34 through the transmission of the first driving gear 32 and the first transmission gear 33. The bottom ends of these driving screws 34 are connected to the bottom of the outer fixed frame 1, and the top ends are connected to the center of the first transmission gears 33 on both sides above. This design allows the lifting platform lifting drive mechanism 3 to control the vertical movement of the lifting platform 2.

[0052] Design of cable conveying mechanism:

[0053] The cable conveying mechanism 4 comprises an upper fixing frame 42 and a lower fixing frame 41 which are symmetrical in the upper and lower directions, and cable conveying rollers 43 are evenly distributed in these fixing frames. The roller surface is arranged in a horizontal funnel shape, so that the space formed between the upper and lower cable conveying rollers 43 is more suitable for the clamping and conveying operation of the cable, and the clamping convex strips 431 are evenly distributed. This design can ensure the stability and safety of the cable during conveying.

[0054] In addition, the telescopic cylinder 45 installed on the left side wall of the upper fixed frame 42 can control the height of the upper fixed frame 42 and several cable conveying rollers 43 inside it, thereby adjusting the gap between the corresponding upper and lower cable conveying rollers 43 to adapt to the clamping and conveying operations of cables of different types.

[0055] Transmission ratio and motion control:

[0056] In addition, the conveying roller driving mechanism 44 disposed on the right side of the lower fixing frame 41 drives the multiple cable conveying rollers 43 below to operate synchronously and in the same direction through the transmission mechanism of the second reduction motor 442 , the second driving gear 443 , and the second transmission gear 444 .

[0057] The transmission ratio between the first drive gear 32 and the first transmission gear 33 is 5:1, and the transmission ratio between the second drive gear 443 and the second transmission gear 444 is 3:1. These transmission ratio settings may be used to control the speed and force of movement of various parts of the device.

[0058] Considerations for device mobility:

[0059] Finally, universal wheels 5 are installed at the four corner ends of the bottom of the outer fixing frame 1. This design can enhance the mobility and flexibility of the entire device, making it easier to move and position the device in the working area.

[0060] Height adjustment process of lifting platform:

[0061] Initial state: the device is in a stopped state, the lifting platform 2 is located in the outer fixed frame 1, and the height of the upper and lower fixed frames of the cable conveying mechanism 4 and the cable conveying roller 43 are adjusted to the initial position.

[0062] Starting device: When the device is started, the first reduction motor 31 starts to run, and drives the rotation of the driving screw rods 34 on both sides through the transmission mechanism of the first driving gear 32 and the first transmission gears 33 on both sides.

[0063] Movement of the lifting platform: With the movement of the driving screw 34, the lifting platform 2 slides up and down in the outer fixed frame 1 to realize the lifting operation. At this time, the cable conveying mechanism 4 is lifted up with the lifting platform 2 to the height of the cable to be laid.

[0064] Cable clamping and conveying operation process:

[0065] At this time, insert one end of the cable to be laid between the upper and lower cable conveying rollers 43, start the operation of the telescopic cylinder 45 to make the upper fixed frame 42 and the cable conveying rollers 43 inside it descend until the upper cable conveying rollers 43 are pressed on the top of the cable to be laid.

[0066] Start the conveying roller driving mechanism, the second reduction motor 442 starts to run, and through the transmission operation of several second driving gears 443 and several second transmission gears 444, the several cable conveying rollers 43 below are driven to start running synchronously and in the same direction, thereby conveying the cables to be laid forward to the belt laying height platform.

[0067] Stop operation: After completing the cable clamping and conveying, the cable conveying mechanism can be stopped to complete the entire working process.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
