Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, and in particular to a waterproof halogen-free low-smoke insulated nylon sheathed cable conduit installation device. Background Technology

[0002] Halogen-free low-smoke cable sheaths are made of halogen-free materials to wrap the cable. They are waterproof, environmentally friendly, safe, wear-resistant, and corrosion-resistant. Therefore, cables protected by this sheath are widely used in railways, high-rise buildings, hospitals, schools, etc. To ensure the proper laying of the cable, appropriate conduit devices are required.

[0003] Existing waterproof, halogen-free, low-smoke insulated nylon-sheathed cable conduit installation devices still have some shortcomings in practical use:

[0004] When laying cables, it is common to use steel cables to pull the cable from one end of the cable through the conduit. However, during the process of pulling the cable into the conduit, the conduit opening is generally not equipped with a guiding and protective device. The steel cable pulls the cable into the conduit by force, which can easily damage the conduit opening. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where pipe openings generally lack guiding and protective devices, and steel cables are used to forcefully pull cables into the pipes, which can easily damage the pipe openings. Therefore, this invention proposes a waterproof, halogen-free, low-smoke insulated nylon-sheathed cable conduit insertion device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waterproof, halogen-free, low-smoke, insulated nylon-sheathed cable conduit installation device includes a mounting frame, a bottom frame below the mounting frame, a top frame above the bottom frame, and two scissor arms between the top frame and the bottom frame. The top of the top frame is fixedly connected to the mounting frame. Two first connecting rods rotatably pass through one side of each of the two scissor arms, and the two first connecting rods are rotatably connected to the top frame and the bottom frame, respectively. Two second connecting rods rotatably pass through the other side of each of the two scissor arms, and the two ends of the two second connecting rods are respectively engaged with the top frame and the bottom frame.

[0008] In one possible design, the inner walls of the top frame and the bottom frame on opposite sides are provided with movable grooves, and movable blocks are slidably connected in each of the four movable grooves, with the two ends of the two second connecting rods fixedly passing through the corresponding movable blocks.

[0009] In a possible design, two horizontal rods are rotationally connected between the two scissors arms, an electric push rod is arranged between the two horizontal rods, the bottom end of the electric push rod is rotationally sleeved on the outer wall of one of the horizontal rods, and the output shaft of the electric push rod is rotationally sleeved on the outer wall of the other horizontal rod.

[0010] In a possible design, four support frames are fixedly arranged in the mounting frame, and the four support frames are arranged in pairs, a limiting slider is slidably connected in each support frame, a spring is fixedly connected in each support frame, one end of the spring is fixedly connected with the limiting slider, and the same vertical roller is rotationally connected between the limiting sliders on the same side, two first rollers are rotationally connected in the mounting frame, a U-shaped frame is slidably connected in the mounting frame, two second rollers are rotationally connected in the U-shaped frame, and a threaded column is threadedly penetrated in the mounting frame, and the bottom end of the threaded column is rotationally connected with the top of the U-shaped frame.

[0011] In a possible design, support plates are hingedly connected to the two sides of the bottom frame, and two universal wheels are fixedly connected to the top of each of the two support plates.

[0012] In a possible design, a plurality of clamping blocks are arranged on the bottom of the bottom frame and the bottom of each of the two support plates, and the clamping blocks on the bottom of the bottom frame and the bottom of the support plates are staggered and matched with each other.

[0013] In this application, when the cable is being threaded, the device is placed at the incoming end of the pipeline, and the two support plates are turned upward, so that the two misaligned clamping blocks on the bottom of the bottom frame and the support plates are away from the horizontal arrangement, thereby increasing the base area of the bottom frame and the ground, and the first roller and the second roller are attached to the incoming end. The output shaft of the electric push rod is elongated, the two horizontal rods are pushed away from each other, the two scissors arms are unfolded, the moving blocks at the two ends of the two second connecting rods slide in the moving grooves respectively, and the two first connecting rods are rotationally connected in the top frame and the bottom frame respectively, thereby supporting one end of the two scissors arms, so that the top frame is lifted above the bottom frame for height adjustment. The top frame adjusts the height of the mounting frame, so that the first roller is flush with the incoming end of the pipeline. The threaded column is rotated, the threaded column is rotated in the mounting frame, the height of the U-shaped frame is adjusted, the distance between the first roller and the second roller is adjusted, the distance between the first roller and the second roller is adjusted, and the distance between the first roller and the second roller is adjusted. The diameter of the cable is the length of the cable, and the cable is moved into the two vertical rollers. As the cable is inserted, the two vertical rollers are supported, so that the two vertical rollers are driven by the two ends of the limiting slider to slide in the support frame, and the spring is pushed and compressed. Through the compression of the four springs, the two vertical rollers are further limited from the two sides of the cable, so that the cable passes through the mounting frame and accurately enters the pipeline.

[0014] Beneficial effects: in the utility model, the first roller, the second roller interval can be adjusted to match the cable diameter through the threaded column, the distance between the two vertical rollers can be pushed through the spring force, to ensure that the cable is not damaged from the first roller, the second roller interval into the pipeline, at the same time, the second connecting rod is slid in the moving groove and the support of the first connecting rod, realizing the quick adjustment of the device height, can adapt to different diameter cables and pipeline specifications, significantly improving the pipe penetrating efficiency;

[0015] In the utility model, the bottom frame and the supporting plate form a large area supporting surface through the two clamping block plug-in cooperation of the bottom respectively, combined with the horizontal placement after the overturning of the supporting plate, effectively increase the ground contact area, enhance the stability of the device in complex terrain or inclined surface, avoid dumping in the pipe penetrating process;

[0016] In the utility model, the bottom of the device can expand the supporting area, at the same time, through the height adjustment of the mounting frame and the distance adjustment of the first roller and the second roller inside the mounting frame, the two vertical rollers are clamped through the spring pushing, make the device more adaptable, also play a good protection role to the pipeline opening, make the pipe penetrating work more convenient, also play a good protection role to the pipeline.
