[0024] The support detection mechanism includes a mounting frame 5 arranged on the base 1, on which a motor 26 and a screw 27 are arranged, and the motor 26 is used to drive the screw 27; a moving seat 19 is slidably installed on the mounting frame 5, and the moving seat 19 and the screw 27 form a spiral pair; an extension electric cylinder 20 is arranged on the moving seat 19, and the extension electric cylinder 20 is used to control the movement of the support detection tube 21.

[0025] The pulling mechanism includes a supporting electric cylinder 25 arranged on the base 1, and the supporting electric cylinder 25 is used to control the movement of the supporting slide 26; the matching part includes a pulling electric cylinder 27 arranged on the supporting slide 26, and a position motor 28 is arranged on the telescopic rod of the pulling electric cylinder 27, and the output shaft of the position motor 28 is connected to the pulling rod 29.

[0026] Working principle: First, put both ends of the chain on the support tube 12, control the position of the push ring 10 by pushing the electric cylinder 8, and drive the push ring 10 to deflect by the deflection motor 9, so that the push ring 10 is coaxial with the support tube 12, and then control the push ring 10 to move to the outside of the support tube 12, and the push ring 10 pushes the chain to accurately position the chain and install it on the support tube 12.

[0027] The overall tensile strength test of the chain can be performed. Specifically, by operating the motor 2 and rotating the screw rod 3, the positioning table 4 is moved, that is, the chain is tensioned under the support and positioning of the support tube 12, thereby completing the overall tensile strength test.

[0028] Furthermore, the motor 26 can be operated and the screw rod 27 can be rotated to move the movable seat 19, that is, adjust the position of the support detection cylinder 21, and control the extension of the support detection cylinder 21 by extending the electric cylinder 20 so that the support detection cylinder 21 is located on the inner side of the chain, and then control the height of the movable seat 19. The chain can be supported by the support detection cylinder 21, that is, the chain can achieve three-area support. In this state, the tensile strength of the chain can be further tested. According to the actual use of the chain, the chain generally needs to be tensioned, and the tensioning is achieved through an external tensioning mechanism. Therefore, here, three supports are provided to perform actual application testing on the chain to test its tensile strength when it has three supports.

[0029] Furthermore, the chain is supported by a support detection cylinder 21, and the intervals between each link of the chain can be detected. Specifically, the chain position is first corrected, and then the push frame 14 is controlled to move by controlling the electric cylinder 13. The push frame 14 pushes the pushing inclined seat 17 to move the engaging seat 15 and the engaging teeth 16. The engaging teeth 16 extend to the outside of the support cylinder 12 and engage with the chain, thereby subsequently driving the chain to move.

[0030] Specifically, after the chain has been meshed, each link can move on the support detection cylinder 21, and the offset contact arc plate 23 is controlled by the interval detection electric cylinder 22 to move to the inner side of the link, that is, between adjacent link rollers. The offset contact arc plate 23 contacts the link rollers, and according to the deflection displacement of the offset contact arc plate 23, the displacement sensor 24 can output a displacement signal of the feedback offset contact arc plate 23, thereby detecting the interval between adjacent link rollers. By continuously driving the chain, each link is located on the support detection cylinder 21 for detection.

[0031] Furthermore, the connection tightness of each chain link can be detected. Specifically, the supporting electric cylinder 25 controls the movement of the supporting slide groove 26 so that the chain is located on the supporting slide groove 26, that is, each chain link can also be moved one by one on the supporting slide groove 26, and the position motor 28 is controlled to move by the pulling electric cylinder 27.

The telescopic rod is inserted into each adjacent chain link by the insertion electric cylinder 30, and the pulling rod 29 is controlled to move by the pulling electric cylinder 27, that is, the two pulling rods 29 move in opposite directions. The installation tightness of the chain link can be detected, that is, the installation tightness between each chain plate and the roller can be detected.
