Embodiment Construction

[0022] Such as Figure 1-Figure 5 As shown, the present invention provides a hydraulic testing machine for multiple steel pipes, which includes a frame 1, a plurality of clamping mechanisms 2 for clamping steel pipes are arranged in the frame 1, and one side of the frame 1 There is a feeding mechanism 3 that pushes the steel pipe to the clamping mechanism 2, and a feeding mechanism 4 is provided on the other side. One end of the frame 1 is provided with a fixing mechanism 5, and the other end is provided with a moving mechanism that pushes the steel pipe to the fixing mechanism 5. Mechanism 6, said fixing mechanism 5 is provided with a hydraulic system 7 for pressurizing the steel pipe. In the above scheme, when the steel pipe is tested for pressure, the steel pipe is first fed to the clamping mechanism 2 through the feeding mechanism 3, the steel pipe can be clamped by the clamping mechanism 2, and the steel pipe is driven by the moving mechanism 6 to move to the fixing mecha...

Abstract

The invention relates to a steel pipe test machine, in particular to a multi-steel-pipe water pressure test machine. The multi-steel-pipe water pressure test machine comprises a machine frame, whereina plurality of clamping mechanisms used for clamping steel pipes are arranged in the machine frame; a feeding mechanism used for pushing and conveying the steel pipes to the clamping mechanisms is arranged at one side of the machine; a blanking mechanism is arranged at the other side; a fixing mechanism is arranged at one end of the machine frame; a moving mechanism for pushing the steel pipes tothe fixing mechanism to be fixed is arranged at the other end; and a water pressure system used for implementing pressurization on the steel pipes is arranged on the fixing mechanism. Each clamping mechanism comprises a base and two clamping plates arranged above the base; at least two L-shaped clamping blocks are respectively arranged on the two clamping plates; the directions of the L-shaped clamping blocks on the two clamping plates are opposite, so that a clamping groove is formed between the adjacent L-shaped clamping blocks on the two clamping plates; the two clamping plates are in staggered arrangement; and a regulating mechanism used for regulating the size of the clamping groove is arranged at the bottom of the two clamping plates.

Description

technical field [0001] The invention relates to a testing machine for steel pipes, in particular to a hydraulic testing machine for multiple steel pipes. Background technique [0002] During the production process of the steel pipe, hydraulic testing is required to ensure that the pressure resistance performance meets the requirements before it can be put into use. [0003] However, in the process of hydraulic testing of steel pipes at present, the traditional process is manual hydraulic testing, which is labor-intensive and inefficient, and it is impossible to test the pressure of multiple steel pipes at one time. For this defect, the present invention makes improvements. Contents of the invention [0004] In order to overcome the disadvantages of the background technology, the object of the present invention is to provide a fully automatic hydraulic testing machine for multiple steel pipes that can perform pressure tests on multiple steel pipes at one time. [0005] The...
