Butt joint device capable of achieving automatic alignment and used for PVC (polyvinyl chloride) pipes

Abstract

The invention discloses a butt joint device capable of achieving automatic alignment and used for PVC pipes, and particularly relates to the technical field of butt joint devices. The butt joint device comprises two main sleeves, wherein automatic alignment mechanisms are arranged at the outer ends of the main sleeves, and tensioning mechanisms are arranged on the two sides of the main sleeves; each automatic alignment mechanism comprises a sliding sleeve, and a fixed circular plate is fixedly arranged at the outer end of each sliding sleeve. By arranging the automatic alignment mechanisms, the fixed circular plates and the sliding sleeves are pushed to slide at the outer ends of the main sleeves, so that hydraulic oil flows into an outer sleeve; inner push rods are pushed to extend, the multiple inner push rods extend synchronously, and the extending distances are the same, so that when anti-skid rubber heads at one end of all the inner push rods make contact with the outer ends of the PVC pipes at the same time, the circle centers of the cross sections of the PVC pipes coincide with the circle centers of the cross sections of the main sleeves, then the two main sleeves are made to slide close to each other along a guide rod, and therefore the two PVC pipes are aligned. Compared with manual alignment, more convenience is achieved, and deviation is avoided.

Description

technical field [0001] The invention relates to the technical field of butt joint devices, in particular to a butt joint device for PVC pipes that can be automatically aligned. Background technique [0002] PVC pipe is a plastic pipe extruded by hot pressing after the combination of polyvinyl chloride resin, stabilizer, lubricant, etc. It has strong heat resistance, ductility, and flexibility, so it is widely used in various related fields. popular. [0003] PVC pipes can be used for drainage, waste water, chemicals, heating and cooling fluids, food, ultra-pure liquids, mud, gas, compressed air and vacuum systems, but these applications generally have long distances and require PVC butt joints between the tubes. [0004] In the process of connecting PVC pipes, since the cross-section of PVC pipes is generally circular, it is difficult to judge the position of the center of the cross-section. In order to ensure alignment, the docking process is mostly done manually, which i...

Problems solved by technology

[0004] In the process of connecting PVC pipes, since the cross-section of PVC pipes is generally circular, it is difficult to judge the position of the center of the cross-section. In order to ensure alignment, the docking process is mostly carried out manually, which is cumbersome. , It takes a while for the adhesive to solidify. During this time, it is necessary to keep the joints of the two PVC pipes tightly bonded. This process is generally manual and very inconvenient.
