Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a device for laying heat tracing cables in roof drainage ditches. Background Technology

[0002] Many building roofs are equipped with drainage ditches. However, in cold northern regions, some snowmelt melts slowly after winter snowfall, or the melted snowmelt freezes into ice as temperatures change. This ice can clog the drainage ditches, causing the meltwater to overflow and form icicles, posing a potential hazard.

[0003] To solve this problem, some large public buildings install snow melting systems in the roof drainage gutters and lay the system's heating cables in the drainage ditches. The usual way to lay the cables is to manually attach them to the gutters on the roof using cable clips, but this method is inefficient. Summary of the Invention

[0008] Preferably, a sliding layer is provided on the outer side of the first clamping plate.

[0009] Preferably, the device comprises a buckle box, a swivel wheel, a gear assembly, a floor wheel, and a limit rod; wherein, the buckle box, swivel wheel, floor wheel, and limit rod are all mounted on the frame; the swivel wheel is mounted at the center of the frame, the buckle box is positioned above the swivel wheel, and the buckle box is in contact with the swivel wheel; there are two floor wheels, which are respectively positioned on the front and rear sides of the swivel wheel, and one of the floor wheels is connected to the swivel wheel via a gear assembly; there are two limit rods, which are respectively positioned between the swivel wheel and the two floor wheels.

[0010] Preferably, the arrangement wheel is provided with a snap-fit ​​groove.

[0012] Preferably, both the first gear and the second gear are gear sets, which are structures consisting of multiple gears of different diameters stacked sequentially; the largest gear in the gear set of the first gear has a smaller diameter than the smallest gear in the gear set of the second gear.

[0013] Preferably, the frame includes: a main frame, a first sub-frame, and a second sub-frame; the main frame is a rectangular structure, and the first and second sub-frames are both fixedly installed on the main frame; the first sub-frame is located at the center of the main frame; four drive devices are respectively located on the inner sides of the four corners of the main frame, and four auxiliary wheels are respectively rotatably installed at the four corners of the main frame; a moving component is installed on the main frame; a snap-fit ​​assembly is installed on the first sub-frame, and both the snap-fit ​​assembly and the spool are connected to the second sub-frame.

[0014] Compared with the closest prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The present invention has two sets of opposing moving components connected together, and each set of opposing moving components is equipped with a forward driving device and a reverse driving device, so that the device can travel in the forward or reverse direction of the drainage ditch in the roof drainage ditch. The number of spools is set to two and is respectively set on the front and rear sides of the snap-fit ​​assembly, so that the device can lay cables in the drainage ditch whether it travels in the forward or reverse direction in the roof drainage ditch.

[0016] 2. In this invention, the floor wheel contacts the bottom of the roof drainage ditch, causing it to rotate, which in turn drives the arrangement wheel to rotate. Each rotation of the arrangement wheel deploys a clip. The cable passes through a limiting rod before being placed in the drainage ditch, and the limiting rod is higher than three-quarters of the way up the arrangement wheel. This ensures the clips are secured to the cable before they fall off. One side of the clip is coated with adhesive, and the other side has an anti-stick structure. After the clip falls to the ground, the floor wheel behind it presses it firmly into place. This increases construction efficiency and quality.

[0017] 3. The auxiliary wheels of this invention are set at the four corners of the frame, enabling the entire device to turn automatically at turns, thus increasing the overall construction efficiency.

[0018] 4. When the device of the present invention is installed in the roof drainage ditch, the first clamping plate compresses the spring. When it moves out of the roof drainage ditch, the spring returns to its original state, the brake lever locks the moving wheel, and the trolley stops, which increases safety.

[0019] 5. The two sets of gears in this invention are configured with different diameters. The gear diameter can determine the arrangement distance of the buckles, thus increasing the flexibility of the buckle arrangement. Attached Figure Description
