A supporting structure for laying building water supply and drainage pipes

Abstract

The present invention discloses a supporting structure for laying water supply and drainage pipes in buildings, comprising a main hanger and an auxiliary hanger, wherein the auxiliary hanger is slidably arranged at the rear side of the main hanger. The present invention relates to the technical field of pipe laying. The supporting structure for laying water supply and drainage pipes in buildings is constructed by assembling the main hanger and the auxiliary hanger into a combined hanger, and arranging a heating spiral laying mechanism, a side frame expansion mechanism, and a docking and fitting mechanism between the main hanger and the auxiliary hanger. This allows the device to not only expand the supporting length, but also automatically heat the spiral laying of the pipes during laying through the synchronous coordination of the heating spiral laying mechanism, the side frame expansion mechanism, and the docking and fitting mechanism. This can not only assist in preventing the water supply pipes from freezing and icing, but also reduce the inconvenience of subsequent manual heating and laying through the automatic heating.

[0041] As a preferred embodiment, in order to facilitate the second perforated ear plate 803 to automatically restore the installation height flush with the first perforated ear plate 801 when the auxiliary hanger 2 is moved, a docking and fitting mechanism 8 is provided on the top of the auxiliary hanger 2. The docking and fitting mechanism 8 includes a first perforated ear plate 801, the first perforated ear plate 801 is fixedly set on the top of the long vertical plate 705, and a U-shaped frame 802 is slidably provided on the top of the short vertical plate 706. The top of the U-shaped frame 802 is fixed. A second perforated ear plate 803 is connected, and a movable rod 804 is fixedly connected to the front and rear sides of one side of the U-shaped frame 802. A lifting rod 805 for use with the movable rod 804 is rotatably provided on the front and rear sides of the rear outward expansion plate 707. A sliding groove 806 is provided on the front and rear sides of the short vertical plate 706. A sliding block 807 is slidably connected inside the sliding groove 806. The two sliding blocks 807 on the same side are fixedly connected to the front and rear sides of the inner cavity of the U-shaped frame 802 on opposite sides.

[0042] The specific steps are as follows:

[0043] Step 1: Pipeline heat tracing and synchronous laying: First, use the first perforated ear plate 801, bolts and punched holes on the building pipe corridor to fix and install several main hangers 1, and then install the pipeline inside the several main hangers 1. When laying the pipeline, the pipeline needs to be lifted above the lower semicircular part of the first arc-shaped supporting groove 3 and the second arc-shaped supporting groove 4. After the pipeline insertion is completed, the pipeline is lowered to make the outer wall of the pipeline fit into the lower semicircular part of the first arc-shaped supporting groove 3 and the second arc-shaped supporting groove 4;

[0044] Then, the auxiliary hanger 2 is dragged backward by the handle. The auxiliary hanger 2 moves backward, driving the rotating rod 603 to move backward. The rotating rod 603 moves backward, driving the gear 604 to engage with the tooth plate 602, causing the rotating rod 603 to drive the first bevel gear 605 to rotate. The first bevel gear 605 is synchronously engaged with the second bevel gear 607, causing the collar 606 to move backward and rotate synchronously. The backward movement and rotation of the collar 606 synchronously drive the storage tube 608 to move and rotate. As the storage tube 608 moves backward and rotates, the electric heating cable 610 inside the storage tube 608 is continuously released and spirally wound around the outer wall of the pipeline.

[0045] Step 2, side frame expansion: During the backward movement of the auxiliary hanger 2, the auxiliary hanger 2 synchronously drives the limit sleeve 711 to move on the surface of the limit slide 710. During the backward movement of the limit sleeve 711, the rear side of the limit sleeve 711 will contact the front side of the pull plate 713 and push the pull plate 713 to move backward. The backward movement of the pull plate 713 pulls the handle inclined plate 712 backward. The backward movement of the handle inclined plate 712 will squeeze and lift the push rod 714, prompting the push rod 714 to drive the front sliding block 702 is lifted to the top of the wide groove cavity inside the slide plate 701. The lifting of the front sliding block 702 will lift the front auxiliary pull rod 704. The front auxiliary pull rod 704 rises through the limit cooperation of the centralized control rod 708 and the through groove 709, and the rear auxiliary pull rod 704 is lifted up synchronously. The rise of the auxiliary pull rod 704 will form an outward expansion rotation cooperation with the outward expansion plate 707, so that the top mounting hole of the auxiliary pull rod 704 fits the mounting punching at the top of the pipe gallery;

[0046] Secondly, the movement of the limiting sleeve 711 synchronously drives the installation box 12, the plugging plate 13 and the second return spring 14 to move. When the auxiliary pull rod 704 is fully extended, the plugging plate 13 will be inserted into the interior of the slot 15 along with the movement of the limiting sleeve 711 to limit the entire assembly.

[0047] Step 3: The installation height of the auxiliary hanger 2 is automatically flush and expanded: when the rear outer expansion plate 707 is turned upward to expand the auxiliary pull rod 704, the rear outer expansion plate 707 will synchronously drive the lifting rod 805 to rise, and the lifting rod 805 rises to lift the movable rod 804, and the movable rod 804 drives the U-shaped frame 802 and the second perforated ear plate 803 to rise until the second perforated ear plate 803 is flush with the first perforated ear plate 801, so that the second perforated ear plate 803 is automatically aligned with the installation punching hole on the top of the pipe gallery. When the U-shaped frame 802 drives the second perforated ear plate 803 to be flush with the first perforated ear plate 801, the U-shaped frame 802 synchronously drives the sliding block 807 to slide to the top of the inner cavity of the sliding groove 806;

[0048] Then, the first perforated ear plate 801, the second perforated ear plate 803, and the auxiliary pull rod 704 are fixed to the top of the pipe gallery in sequence by bolts, and finally the threaded rod 18 is screwed to drive the pressure plate 19 to press the top of the pipe downward to fix the pipe.
