Problems solved by technology
[0002] At present, the known peeling test methods for the adhesion strength of polyolefin plastic anticorrosion layers such as PE or 3PE on the steel pipe surface mainly include hand-operated, electric, etc. The hand-operated test data has a large error and basically does not meet the test requirements. The chain belt bound on the outer circumference of the steel pipe is used as a moving mechanism. This method is more troublesome to operate and clamp. There is also a strip that is wound on the strip drum, and the rotation of the strip drum completes the strip. The thickness of the peeling strip changes, the tension and speed will also change, resulting in inaccurate force measurement

Embodiment Construction
[0014] Attached below Figure 1-2 Specific embodiments of the present invention will be further described.
[0015] see Figure 1-2 : During use, clamp the unloaded strip strip lock 9 and the stripped strip 11 that has been tilted up in advance, place the machine above the steel pipe 12, and hang the strip strip lock 9 that has clamped the strip strip. The ring is hung on the hook of the sensor 8, the peeled strip lock 9 locks the peeled strip 11, and the hanging ring on it is connected with the hook of the sensor 8. Rotate the operation switch 3 to control the start of the walking motor 14, and the walking motor 14 drives the walking chain 22 to drive the trolley wheel 10 to rotate, so that the trolley box 7 can walk according to the peeling direction, and the output key shaft of the lifting motor 1 and the shaft coupling 2 are in clearance fit in the radial direction , the coupling 2 and the lead screw 5 are transitionally fitted, and the bottom end of the lead screw 5 is ...

The invention provides a stripping strength test machine for a PE anticorrosion layer of the surface of a steel pipe. The test machine includes a support, a lifting motor fixing board and a trolley case, which are connected in a triangular structure. A lifting motor is installed on the lifting motor fixing board and is in anti-jamming radial clearance fit connection with a coupling. The coupling is in transition connection with the upper end of a screw rod. The lower end of the screw rod is inserted into a bottom bearing of the screw rod is in anti-jamming clearance fit connection with same. Alinear railway is mounted on the lower end of the lifting motor fixing board. A sliding piece is located in the trolley case and is mounted on the linear railway. A dual-eccentric wheel stripping barlatch is connected to the sliding piece via a sensor. An electric control and measurement unit, including a battery, is arranged in the trolley case and is used for controlling the lifting motor anda traveling motor. The machine completely satisfies the demand in technical specification of a stripping test, is automated and has simple operations, allows a steel pipe to be mounted quickly and isportable.
Description
technical field [0001] The invention belongs to a testing device, in particular to a testing device for the bonding strength of a steel pipe anticorrosion layer. Background technique [0002] At present, the known peeling test methods for the adhesion strength of polyolefin plastic anticorrosion layers such as PE or 3PE on the steel pipe surface mainly include hand-operated, electric, etc. The hand-operated test data has a large error and basically does not meet the test requirements.
