Description

Technical Field

[0001] The utility model relates to the technical field of sand-filled pipe solidification, in particular to a glass fiber reinforced plastic sand-filled pipe solidification device. Background Art

[0002] Glass fiber reinforced plastic sand-filled pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. It is resistant to chemical corrosion, lightweight and high-strength, does not scale, and has strong seismic resistance. Compared with ordinary steel pipes, it has the advantages of long service life, low overall cost, quick installation, safety and reliability. However, since the baking plate is a flat structure and the outer surface of the pipe is an arc-shaped, it is easy to cause uneven heating in various parts of the pipe. In severe cases, it may cause part of the outer wall of the pipe to be scorched or even damaged. Patent documents have now been issued to improve this.

[0003] For example, Chinese patent CN210880485U, a fiberglass reinforced plastic sand-filled pipe curing device, relates to the field of pipe curing, and includes a fixed base plate, the upper surface of which is respectively provided with a sliding base, a sand-filled pipe placement platform, and a fixed foot, the upper surface of the sliding base is fixedly connected to a first support plate, one side of the first support plate is fixedly connected to a support shaft, one end of the support shaft is rotatably connected to a curing system via a bearing, the curing system includes a first drying ring and a second drying ring, the lower end of the fixed foot is fixedly connected to the fixed base plate, the upper surface of the fixed foot is fixedly connected to an automatic telescopic rod, and the circumference of the automatic telescopic rod is fixedly connected to a sand-filled pipe lifting and lowering support plate. This device for curing fiberglass reinforced plastic sand-filled pipes solves the problem that the baking plate is a flat plate structure while the outer surface of the pipe is an arc surface, which easily causes uneven heating of the pipe, and in severe cases, causes part of the outer wall of the pipe to be scorched and damaged.

[0004] Although the equipment in the above document can evenly heat and bake the surface of the sand pipe, it still has obvious defects in actual use, such as:

[0005] The device is equipped with two heating rings that are nested together. Although it can evenly bake the inside and outside of the sand pipe, it can only heat and cure pipes of one diameter width. If the diameter of the pipe changes, the device cannot be used, reducing its overall practicality.

[0006] Therefore, a glass fiber reinforced plastic sand-filled pipe solidifying device that can improve applicability is now designed to solve this type of defect. Utility Model Content

Threaded rod 5, and the bidirectional threaded rod 5 is threadedly connected to two guide slide seats 6, the surface and rear of the heating chamber 1 are provided with operation ports 20, the right side of the top of the inner cavity of the heating chamber 1 is rotatably connected to a reciprocating screw rod 8 through an opening, the right side of the heating chamber 1 is fixedly connected to a motor 9 through a bracket, the motor 9 is a servo motor, and the output shaft of the motor 9 is fixedly connected to the right end of the motor 9 through a coupling, an upper guide groove 10 is provided at the top of the inner cavity of the heating chamber 1, and a guide slide plate 12 is slidably installed on the inner side of the upper guide groove 10.

[0025] During use, the sand tube is first moved to the interior of the heating chamber 1 using the equipment, so that the side plate 4 is located inside the sand tube. Then the staff shakes the bidirectional threaded rod 5 from the operation port 20. When the bidirectional threaded rod 5 is shaken, the two arc-shaped top plates 7 are driven to move through the two guide slides 6 to support and fix the two sides of the inside of the sand tube. Then the motor 9 and the heating frame 13 are started. After the heating frame 13 is started, the sand tube will be heated. The start of the motor 9 will drive the heating frame 13 to move left and right through the rotation of the reciprocating screw 8 and the limit of the upper guide slot 10 to uniformly heat and solidify.

[0026] Furthermore, the surface of the reciprocating screw rod 8 is connected to a threaded sleeve 11 located inside the heating chamber 1, and the threaded sleeve 11 is fixedly connected to the guide slide 12, the bottom of the threaded sleeve 11 is fixedly connected to a heating frame 13, and an electric heating wire is provided on the inner side of the heating frame 13.
