Description

Technical Field

[0001] The invention relates to the technical field of pipeline processing, in particular to a winding frame for winding a glass fiber reinforced plastic pipeline. Background Art

[0002] FRP pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. It is made of glass fiber with a resin matrix, which is wound layer by layer on a rotating pipe according to the process requirements, and quartz sand is evenly spread between the fibers at a long distance as a sand layer. Its pipe wall structure is reasonable and advanced, which can give full play to the role of the material. Under the premise of meeting the use strength, the rigidity is improved, ensuring the stability and reliability of the product.

[0003] For example, Chinese patent CN108673908B proposes a processing device for pipe winding glass fiber reinforced plastics, including a winding frame, a track, a trolley, a glass fiber wire discharging mechanism and a sand discharging mechanism arranged on the trolley, the winding frame includes a support, a transmission shaft rotatably arranged on the support, a connecting shaft that is anti-rotationally matched with the transmission shaft and can move left and right relative to the transmission shaft, and a mold core rod whose one end can be plugged and anti-rotationally matched with the connecting shaft; the mold core rod is provided with an anti-rotation structure that is anti-rotationally matched with the material sleeved on the mold core rod, and the anti-rotation structure includes a first anti-rotation member fixedly connected to one end of the mold core rod and a second anti-rotation member detachably connected to the other end of the mold core rod.

[0018] The present invention provides a winding frame for winding a glass fiber reinforced plastic pipe, which has the following beneficial effects:

[0019] (I) The winding frame for winding the FRP pipe, through the installation of the demoulding device, utilizes the third electric telescopic rod to contract, drives the rectangular plate to move toward the position of the round rod, and the limit plate gradually approaches the round rod.

At this time, the rotating rod rotates along the first rotating seat with the rotating sleeve, and the second rotating seat drives the driving motor to slide along the slide rail while descending. As the first electric telescopic rod rises, the greater the inclination of the demoulding device, the pipe is clamped by the external clamping mechanism, the rotating rubber sleeve is rotated to make the threaded rod rotate out of the threaded hole, and the reinforcement plate is taken out. At this time, the processed pipe is smoothly taken out along the inclined demoulding device, so that the purpose of quickly replacing the pipe is achieved and the work intensity of the operator is reduced.

[0021] (III) The winding frame for winding the FRP pipes, through the installation of two sets of demoulding devices, enables the feeding mechanism to simultaneously perform winding processing on two sets of pipes, thereby improving the efficiency of the pipe winding processing and improving the practicality of the device.
