Description

Technical Field

[0001] This utility model relates to the field of pipe testing technology, specifically to a pipe pressure resistance testing device. Background Technology

[0002] Pipes are the materials used to make pipe fittings. Different pipe fittings require different pipe materials, and the quality of the pipe material directly determines the quality of the pipe fittings. This type of pipe material is widely used in construction projects, power plants, chemical plants, and other industries. The pressure test involves applying a load higher than the working pressure to test the strength of the pipe material under high pressure conditions, ensuring that it can withstand the design pressure without rupture or failure.

[0003] For example, the announcement number CN217384980U is titled "A Sealing Fixture for Pipe Pressure Burst Test". This device includes a pressure test fixture, which includes a pressure test fixture assembly and a protective device. It mainly solves the problem that if the pipeline bursts due to overpressure during the pressure test, it will cause damage to the surrounding area. By setting a stainless steel glass tube to cover and protect the pipeline, it prevents the pipeline burst fragments from flying to the surrounding area.

[0004] During use, the aforementioned device breaks apart inside the protective cover. However, it is inconvenient to collect the fragments inside the protective cover during subsequent cleaning, as the protective cover must be disassembled to clean the fragments, which is quite inconvenient. Therefore, we propose a pipe pressure resistance testing device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a pipe pressure resistance testing device to solve the problem mentioned in the background art that it is inconvenient to collect the debris inside the protective cover during subsequent cleaning, and the protective cover must be disassembled to clean the debris, which is quite inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe pressure resistance testing device, comprising a base, a support, and a top frame, wherein the support is installed on the upper end of the base, the top frame is installed on the upper end of the support, and the top frame and the support are supported by a triangular support frame;

[0007] Also includes:

[0008] A protective cover is installed at the front end of a bracket. A mounting bracket is provided at the rear end of the protective cover, and the rear end of the mounting bracket is connected to the bracket. The mounting bracket is installed at the front end of the bracket via the bracket. A tray is installed at the bottom of the protective cover, and the tray is movably fitted against the bottom of the protective cover. A connecting bracket is installed at the rear end of the tray, and the rear end of the connecting bracket extends into a through groove on the surface of the bracket. A first motor is installed on the outer side of the bracket, and the first motor is connected to the rear end of the connecting bracket. The first motor drives the connecting bracket to swing the tray. A cylinder is installed at the upper end of the top frame, and a pressure plate is installed at the bottom of the top frame. The pressure plate and the cylinder are connected by a telescopic rod. A pressure sensor is installed on the bottom surface of the pressure plate.

[0009] Preferably, a fixing frame is installed at the front end of the upper surface of the base, and a screw is installed between the fixing frame and the bracket. The two ends of the screw are installed between the bracket and the fixing frame through bearings. A second motor is installed at the front end of the fixing frame and is connected to the screw. A support rod is movably engaged below the tray. The bottom of the support rod is movably attached to the upper surface of the base, and the support rod is threadedly connected to the screw through a threaded hole on the surface.

[0010] Preferably, a storage box is installed at the rear end of the support rod, and the upper surface of the storage box is open.

[0011] Preferably, the upper surface of the base is provided with a sliding groove, the sliding groove is located below the screw, and the slider at the bottom of the support rod is slidably engaged inside the sliding groove.

[0012] Preferably, the bottom sides of the tray are symmetrically provided with limiting baffles, and the support rod is movably engaged between the limiting baffles.

[0013] Preferably, the upper surface of the tray is provided with a baffle, and the baffle forms an opening at the front end of the upper surface of the tray.

[0014] Preferably, a movable cover is installed at the front end of the protective cover, and the movable cover is engaged and fixed to the protective cover by a snap fastener, and a pressure relief valve is installed on the outer side of the protective cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) By fixing the protective cover to the front end of the bracket and installing a tray at the bottom of the protective cover, the tray is installed at the front end of the bracket through the connecting frame at the rear end. The tray is driven by a motor to swing. When the pipe bursts during the test, the broken fragments fall on the surface of the tray. The tray is driven by a motor to flip downwards, so that the fragments fall under the action of gravity, making it convenient and quick to remove the fragments from the protective cover.

[0017] (2) By setting a support rod under the tray, the bottom surface of the tray can be supported by the support rod during the pressure test to prevent the tray from shifting due to excessive pressure on the pipes from the pressure plate above. At the same time, the support rod is moved by the screw drive. When it is necessary to clean up the debris on the surface of the tray, the support rod is moved out of the bottom of the tray by the screw. Then the motor drives the tray to flip so that the tray can be tilted. A storage box is set at the rear end of the support rod. When the tray is flipped to a certain position and aligned with the storage box, the debris can fall into the tray, which is convenient for collection and sorting. Attached Figure Description
