Description

Technical Field

[0001] This utility model relates to the field of municipal drainage technology, and in particular to a fixing device for the construction of municipal drainage pipelines. Background Technology

[0002] Drainage pipes are mainly responsible for draining rainwater, sewage, and agricultural irrigation. They are divided into plastic drainage pipes, concrete pipes, and reinforced concrete pipes. They are widely used in drainage fields such as highways, railway subgrades, subway projects, waste landfills, tunnels, green belts, sports fields, and slope protection due to high water content, as well as underground irrigation and drainage systems in agriculture and horticulture. Pipe fixing devices are usually used to support the pipes and fix the pipe joints to prevent loosening due to unstable fixing.

[0003] Existing technologies, such as Chinese Patent Publication No. CN216590274U, disclose a pipe fixing device for municipal water supply and drainage construction. This device includes a connecting plate with a groove, a slider slidably connected inside the groove, a lower collar welded to the upper surface of the slider, an assembly seat welded to the surface of the lower collar, an A-threaded hole on the upper surface of the assembly seat, an A-bolt for fixing the upper collar threaded through the threaded hole, a hole for fixing a rotating shaft at the top of the upper collar, a screw with a collinear axis rotatably mounted inside the rotating shaft, a handle for driving the screw rotation welded to the top of the screw, a threaded sleeve threaded to the bottom of the screw, a clamping plate welded to the lower end of the threaded sleeve, and a connecting seat welded to the lower surface of the connecting plate. This device offers convenient and stable pipe installation and connection, allows personnel to control the support height of the device as needed, reduces corrosion of the lower and upper collars by moisture below, and thus extends the service life of the device. However, this utility model uses bolts to fix the upper and lower collars. When assembling and disassembling the fixing device and the pipe, multiple bolts need to be installed and removed, which is time-consuming and labor-intensive.

The end of the connecting rod 704 away from the cylinder 703 is rotatably connected to the surface of the T-block 3.

[0028] The effect achieved by the above components is as follows: when the rotating shaft 701 rotates, it drives the disc 702 and the cylinder 703 to rotate. The connecting rod 704 can drive the T-block 3 to slide along the T-groove 2, thereby adjusting the distance between the two sets of lower fixed seats 4.

[0029] Specifically, a turntable 705 is fixedly connected to the surface of the rotating shaft 701, a gear 706 is fixedly connected to the surface of the rotating shaft 701, a slide rod 707 is fixedly connected to the surface of the mounting base 1, a movable plate 708 is slidably connected to the surface of the slide rod 707, and a spring 709 is sleeved and connected to the surface of the slide rod 707. One end of the spring 709 is fixedly connected to the surface of the mounting base 1, and the other end of the spring 709 is fixedly connected to the surface of the movable plate 708.

[0030] The effects achieved by the above components are as follows: the turntable 705 is set to facilitate the rotation of the shaft 701; the gear 706 is set to cooperate with the rack plate 710 to fix the shaft 701; the slide bar 707 is set to facilitate the movement of the movable plate 708; the movable plate 708 is set to disengage the rack plate 710 from the gear 706 when the movable plate 708 slides along the slide bar 707 and tightens the spring 709, so as to facilitate the rotation of the shaft 701; the spring 709 is set to both lock the rack plate 710 into the gear 706 and facilitate the reset of the movable plate 708 and the rack plate 710 by utilizing its rebound effect.

[0031] Specifically, a rack plate 710 is fixedly connected to the surface of the movable plate 708, and the rack plate 710 meshes with the surface of the gear 706. A handle 711 is fixedly connected to the surface of the movable plate 708.

[0032] The effects achieved by the above components are as follows: the rack plate 710 is set to cooperate with the gear 706 to fix the rotating shaft 701 and prevent the distance between the two sets of lower fixed seats 4 from changing arbitrarily; the handle 711 is set to facilitate pulling the movable plate 708.

[0033] Working principle: By setting up the loading and unloading mechanism 6, the mounting base 1 is first fixedly installed, the pipe is placed on the lower fixed base 4, and the upper fixed base 5 is held by the through groove 610. The rack plate 602 is inserted into the sliding groove 601. As the rack plate 602 slides downward, it squeezes the retaining teeth 605, causing the L-shaped plate 604 to slide into the relief groove 603 and tighten the spring 607. When the rack plate 602 slides to the appropriate position, the retaining teeth 605 clamp the rack plate 602 under the rebound action of the spring 607, fixing the upper fixed base 5. The spring 611 and the soft pad 612 work together to keep the pipe in place. The pipe is stably clamped by the lower fixed seat 4 and the upper fixed seat 5. When disassembly is required, simply grasp the two sets of handles 609 and pull the L-shaped plate 604, so that it slides along the guide rod 606 while tightening the spring 607, so that the L-shaped plate 604 slides into the relief groove 603. The rack plate 602, which is no longer restricted by the locking teeth 605, can move freely. Grasp the through groove 610 and pull the upper fixed seat 5 upward. By setting the loading and unloading mechanism 6, when fixing the pipe, unlike the traditional bolt connection, the lower fixed seat 4 and the upper fixed seat 5 can be quickly and effortlessly assembled and disassembled, which effectively improves the convenience of the equipment.

[0034] Furthermore, by setting an adjustment mechanism 7, the pipeline is fixed using two sets of lower fixed seats 4 and upper fixed seats 5. When it is necessary to adjust the distance between the two sets, first pull the handle 711 to make the movable plate 708 slide along the slide rod 707. While tightening the spring 709, the rack plate 710 disengages from the gear 706. After losing its restraint, the turntable 705 is rotated, causing the rotating shaft 701 to drive the disc 702 and the cylinder 703 to rotate. The connecting rod 704 drives the T-block 3 to slide in the T-slot 2 to the appropriate position. Then, release the handle 711. Under the rebound action of the spring 709, the movable plate 708 returns to its original position, and the rack plate 710 locks the gear 706 again, fixing the rotating shaft 701. By setting the adjustment mechanism 7, when fixing the pipeline using two sets of lower fixed seats 4 and upper fixed seats 5, the distance between the two sets of lower fixed seats 4 and upper fixed seats 5 can be adjusted as needed to increase stability, thus effectively improving the applicability of the equipment.
