Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting pressure testing, in particular to a plastic pipe pressure testing box. Background Art

[0002] Plastic pipes are generally made of synthetic resin, that is, polyester, with stabilizers, lubricants, plasticizers, etc., and are extruded in a pipe making machine by the "plastic" method. They are mainly used as pipes for tap water supply systems in buildings, drainage, exhaust and sewage sanitary pipes, underground drainage systems, rainwater pipes, and threading pipes for wire installation, etc. Because plastic pipes are often subjected to great pressure during use, the pressure resistance performance needs to be tested in the process of plastic pipe quality inspection.

[0003] After searching, it was found that the publication number is CN215727354U, and the name is a plastic pipe pressure testing machine that is easy to install. The application proposes that during the use of the pressure testing machine, the pressure testing machine needs to be placed horizontally to ensure the accuracy of the test results. At present, the horizontal position of the testing machine is mostly adjusted manually, which often takes a lot of time and affects the installation efficiency of the testing machine. The motor is started by the PLC controller, and the output shaft of the motor drives the driving gear to rotate. Under the transmission action of the synchronous belt, the four synchronous pulleys rotate synchronously. At this time, the rotation of the synchronous pulley will drive the screw to rotate unlimitedly. During the rotation process, the electric push rod is started, and the telescopic end of the electric push rod pushes the slide block to move a certain distance. At this time, the card plate contacts the outer arc surface of the screw, and the spring The spring is in a contracted state, and the friction between the card plate and the screw is less than the force exerted by the synchronous pulley on the screw. As the screw continues to rotate, under the elastic force of the spring, the end of the card plate away from the slide block enters the vertical card slot, and the end of the card plate close to the slide block is still inside the slide block, limiting the rotation of the card plate, and then limiting the rotation of the screw. At this time, the rotation of the synchronous pulley will drive the screw to move up and down. Through the data detected by the angle measuring instrument, the PLC controller controls the four screws to move up and down respectively, and adjusts the entire device to a horizontal state. Then, the plastic pipe is pressure tested by the test organization to facilitate the adjustment of the horizontal position of the entire device, reduce the time required for the installation of the entire device, improve installation efficiency, save time, improve detection efficiency, and make the detection results more accurate.

[0004] The existing technology has the following problems:

[0005] 1. This application uses very precise angle measuring instruments and other equipment, and a large number of precise equipment are arranged, which significantly increases the production cost and use cost, and the subsequent maintenance cost will also increase significantly. Compared with the traditional three-point foot screw adjustment level, the structure is more complicated and more expensive, which is not conducive to popularization and use.

[0006] To this end, we proposed a plastic pipe pressure test box to solve the above-mentioned drawbacks. Utility Model Content
