[0026] The present invention will be further described below with reference to the accompanying drawings. Figure 1-2 :

[0027] A winding water pipe life detection machine comprises a base 1, a hose reel 2 is arranged on one side of the base 1, a roller 3 is arranged on the other side, a spiral guide groove 4 is arranged on the roller 3, one end of a water pipe 5 to be detected is wound in the hose reel 2, and the other end is fixed on the roller 3, the roller 3 is driven by a power device to rotate forward and reverse periodically, and the water pipe 5 to be detected is wound or unwound along the spiral guide groove 4 when the roller 3 rotates forward and reverse.

[0028] When in use, the water pipe 5 to be tested is wound into the hose reel 2, and then its movable end is pulled out and fixed on the drum 3. The power device is started, and the power device drives the drum 3 to rotate periodically. When the drum 3 rotates in the winding direction, the water pipe 5 to be tested will be wound onto the drum 3. Due to the guiding effect of the spiral guide groove 4, the water pipe 5 to be tested will be wound along the spiral guide groove 4, and the hose reel 2 will unwind synchronously; when the drum 3 rotates in the unwinding direction, the water pipe 5 to be tested will be unwound along the spiral guide groove 4, and the hose reel 2 will rewind synchronously. When the number of periodic forward and reverse rotations of the drum 3 reaches the set number, the water pipe 5 to be tested will also be wound and unwound a corresponding number of times, and the appearance and performance of the water pipe 5 to be tested will be tested to determine the service life of the water pipe 5 to be tested.

[0029] The fixed position of the end of the water pipe 5 to be tested is the starting end of the winding of the spiral guide groove 4, which can make the water pipe 5 to be tested enter the spiral guide groove 4 more easily; further, the end of the water pipe 5 to be tested is detachably fixed by a fastener, and preferably, the fastener is a saddle buckle.

[0030] The drum 3 is rotatably arranged on the base 1 through a pair of drum brackets, and the rotating shaft of the drum 3 is supported on the drum brackets through bearings.

[0031] A slide rail 6 is provided on the adjacent inner side of the above-mentioned drum 3, a bracket 7 is slidably provided on the slide rail 6, a guide wheel 8 is rotatably provided on the bracket 7, a circumferential groove 9 is provided on the guide wheel 8, the water pipe 5 to be inspected is introduced into the spiral guide groove 4 from the lower end of the guide wheel 8, and the bracket 7 can slide freely on the slide rail 6. When the water pipe 5 to be inspected is wound or unwound, the part connected to the guide wheel 8 will produce axial displacement (axial direction of the rotating shaft of the drum 3) as the number of winding turns in the spiral guide groove 4 is different, thereby pulling the bracket 7 to slide synchronously, thereby playing a role of precise guidance.

[0032] The slide rail 6 is mounted on the base 1 via a pair of slide rail seats. Preferably, the slide rail 6 is parallel to the axis of the drum 3 .

[0033] A limiting wheel 10 is rotatably provided on the bracket 7, and a circumferential convex ring 11 is provided on the limiting wheel 10. The limiting side surface of the circumferential convex ring 11 is in contact and connected with the winding of the water pipe 5 to be inspected. Through the limiting effect of the limiting wheel 10, the water pipe 5 to be inspected can be prevented from deviating when being wound and unwound, so that it can be accurately wound into the spiral guide groove 4.

[0034] Preferably, the guide wheel 8 and the limiting wheel 10 are distributed up and down.

[0035] In this embodiment, the power device is a bidirectional motor, and the motor shaft of the bidirectional motor is transmission-connected to the rotating shaft of the drum 3, and the transmission connection is in the form of a synchronous belt connection.

[0036] A mounting seat 12 is provided on the base 1, and a fixed shaft 13 is provided on the mounting seat 12. The hose reel 2 is rotatably provided on the fixed shaft 13. When the drum 3 rotates, the hose reel 2 swings accordingly. The movable hose reel 2 avoids the water pipe 5 to be tested from being squeezed, rubbed, and bent by the outlet edge of the hose reel 2 during the process of reeling and unreeling, thereby preventing the detection data from being inaccurate.

[0037] The groove width of the spiral guide groove 4 is the same as the outer diameter of the water pipe 5 to be detected, so that the water pipe 5 to be detected can be tightly wound in the spiral guide groove, which saves space and facilitates winding.

[0038] The winding water pipe life tester of this embodiment can test two or more water pipes at the same time:

[0039] Two hose reels 2 are arranged side by side on the base 1, and two sections of spiral guide grooves 4 are arranged on the drum 3. The hose reels 2 and the spiral guide grooves 4 are arranged one by one to form two detection units, and each detection unit detects a water pipe to be detected 5. In this embodiment, the fixing points of the two water pipes to be detected 5 are both located in the middle of the drum 3, and the spiral directions of the two sections of spiral guide grooves 4 are both rolled from the inside to the outside.

[0040] Corresponding to the two detection units, the present embodiment also simultaneously arranges two groups of guide wheels 8 and limit wheels 10, and its specific structure is: the adjacent inner side of the drum 3 is arranged with a slide rail 6, and a plurality of brackets 7 corresponding to the plurality of detection units are slidably arranged on the slide rail 6, and a guide wheel 8 and a limit wheel 10 are rotatably arranged on each bracket 7, and a circumferential groove 9 is arranged on the guide wheel 8, and the water pipe 5 to be detected is introduced into the spiral guide groove 4 from the lower end of the guide wheel 8, and a circumferential convex ring 11 is arranged on the limit wheel 10, and the limiting side surface of the circumferential convex ring 11 is in contact and connected with the winding of the water pipe 5 to be detected.
