Description

Technical Field

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

[0002] Seamless steel pipe is a type of steel pipe without welded joints. It is usually produced through solid-state pressure processing or rotary processing. This type of steel pipe has no obvious weld seams, thus possessing high strength and pressure resistance. It is suitable for various high-pressure, high-temperature, or critical engineering and applications. Seamless steel pipe is commonly used in petroleum, chemical, natural gas, heating, and water supply fields. It is highly favored due to its excellent sealing and corrosion resistance. After the production of seamless steel pipe, a pressure resistance testing agency is required to test its pressure resistance performance.

[0003] Existing pressure resistance testing mechanisms for seamless steel pipes use fixed testing components, which cannot be quickly adjusted according to the outer diameter of the seamless steel pipe. The seamless steel pipe is prone to displacement during pressure resistance testing, affecting the accuracy of the pressure resistance test. Therefore, we propose a pressure resistance testing device for seamless steel pipes. Utility Model Content

[0004] The purpose of this invention is to provide a pressure testing device for seamless steel pipes, which has the effect of quickly replacing the testing fixing components. This solves the problem that the existing pressure testing mechanisms for seamless steel pipes use fixed settings for the testing fixing components, which cannot be quickly adjusted according to the outer diameter of the seamless steel pipe. This also makes the seamless steel pipes prone to displacement during pressure testing, affecting the accuracy of the pressure testing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure resistance testing device for seamless steel pipes, comprising a testing platform and a support base, wherein a dovetail groove A is provided in the middle of the top of the testing platform, a testing base is clamped in the dovetail groove A on the top of the testing platform, a support base is installed near the middle of the rear surface of the top of the testing platform, a cylinder is installed on the top of the support base, a pressure sensor is installed on the output shaft of the cylinder, a connecting seat is installed at the bottom of the pressure sensor, and a testing head is clamped in the bottom of the connecting seat through the dovetail groove B.

[0006] Preferably, a locking device is screwed into the center of the bottom of the testing platform, and a locking bolt is screwed into the center of one side of the connecting seat.

[0007] Preferably, a protective cover is installed on the top of the testing platform near the outer surface, and side doors are installed on both sides of the front surface of the protective cover via hinges, with buckles installed at the gap between the side doors on both sides.

[0008] Preferably, a fixing frame is installed in the middle of one side of the testing platform, and a control box is installed on the top of the fixing frame. The control box is electrically connected to the pressure sensor.

[0009] Preferably, a touch screen is installed on the front surface of the control box near the top, and a control panel is installed on the front surface of the control box near the bottom.

[0010] Preferably, electric telescopic devices are installed on both sides of the bottom of the testing platform, and a lifting seat is installed on the top of the testing platform at the output shaft of the electric telescopic device. A conveyor belt is installed on the top of the lifting seat through a support frame.

[0011] Preferably, limit rods are installed on both sides of the bottom of the lifting seat, and the limit rods pass through the testing table.

[0012] Preferably, a seamless steel pipe is clamped on the top of the detection seat, and the top of the detection seat fits the outer surface of the seamless steel pipe, and the bottom of the detection head fits the outer surface of the seamless steel pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model achieves the effect of quickly replacing the testing and fixing components by setting dovetail groove A, dovetail groove B, a testing seat, and a testing head. Dovetail groove A is provided in the middle of the top of the testing platform. A testing seat is clamped in dovetail groove A at the top of the testing platform. A support seat is provided in the middle of the top of the testing platform near the rear surface. A cylinder is provided on the top of the support seat. A pressure sensor is provided on the output shaft of the cylinder. A connecting seat is provided at the bottom of the pressure sensor. A testing head is clamped in the bottom of the connecting seat through dovetail groove B. This solves the problem that the testing and fixing components of the existing seamless steel pipe pressure resistance testing mechanism are fixed and cannot be quickly adjusted according to the outer diameter of the seamless steel pipe. The seamless steel pipe is prone to displacement during pressure resistance testing, which affects the accuracy of the pressure resistance testing. This invention reduces the probability of displacement of the seamless steel pipe, thereby improving the accuracy of the pressure resistance testing of the seamless steel pipe.

[0015] 2. This utility model achieves the effect of rotating seamless steel pipes by setting up a lifting seat, an electric telescopic device, and a conveyor belt. Electric telescopic devices are set on both sides of the bottom of the testing platform, and a lifting seat is set at the top of the testing platform where the output shaft of the electric telescopic device is located. A conveyor belt is set on the top of the lifting seat through a support frame. This solves the problem that existing seamless steel pipes require manual rotation to adjust the testing position during pressure resistance testing, resulting in poor convenience of pressure resistance testing. This improves the convenience of testing seamless steel pipes, thereby increasing the testing efficiency.

[0016] 3. This utility model achieves the effect of protecting the testing personnel by setting up a protective cover, side doors, and buckles. A protective cover is set on the top of the testing platform near the outer surface, and side doors are set on both sides of the front surface of the protective cover via hinges. Buckles are set at the gap between the side doors to solve the problem that existing seamless steel pipes are prone to breakage during pressure resistance testing, and the broken fragments are easy to fly and cause injury to the testing personnel. This reduces the probability of flying fragments from the broken seamless steel pipes, thereby ensuring the safety of the pressure resistance testing personnel. Attached Figure Description
