During specific work, the first step: the two ends of the anchor chain required to be subjected to the tensile strength test are placed on the corresponding bearing plates 41, and the metal rings at the two ends are clamped into the arc plates 42, so that the anchor chain is preliminarily supported and kept preliminarily tight, the anchor chain is conveniently clamped by the first clamping part 55 and the second clamping part 56 in the subsequent stretching mechanism 5, and further the subsequent tensile strength test is conveniently performed.
And a second step of: after the anchor chain keeps preliminary and straightens, take the first clamping part 55 and the second clamping part 56 between the two U-shaped plates 54 on the left side as an example, move the U-shaped plates 54, namely, the upper U-shaped plates 54 move forward, the lower U-shaped plates 54 move backward, the U-shaped plates 54 drive the two L-shaped plates 540 on the U-shaped plates to move synchronously, so the front and back opposite L-shaped plates 540 are close to each other, at this time, the corresponding two clamping plates 552 are located at two sides of the corresponding metal ring cross shaft, the first and second hydraulic cylinders 581 and 582 work to enable the telescopic ends of the first hydraulic cylinder 581 to retract, the telescopic ends of the first hydraulic cylinder 581 drive the clamping columns 551 in the first clamping part 55 to move synchronously through the connecting plates 580, the clamping columns 551 drive the corresponding clamping plates 552 to move synchronously towards the other clamping plates 552 corresponding to be fixedly arranged, the two clamping plates 552 are mutually matched, the convex structure is clamped into the other clamping grooves 553, at this time, the cross shaft is located between the two clamping plates 552, the cross shaft is locked, the first clamping plate 552 is matched with the second clamping plate 55 in the horizontal direction, and the second clamping part 55 is limited by the first clamping plate 55, and the second clamping plate 55 is mutually limited by the first clamping plate and the second clamping plate 55 is matched with the second clamping plate 55 in the horizontal direction.
And a third step of: in the process of mutually supporting and locking the two clamping plates 552, the clamping plates 552 drive the moving plates 571 and the fixed blocks 572 to synchronously move to two sides of the corresponding transverse shafts through the two movable columns 570, at the moment, the arc surfaces of the fixed blocks 572 are opposite to the arc sections of the adjacent metal rings, then the driving plates 583 are operated by the external hydraulic cylinders to drive the trapezoid blocks 584 to approach the transverse shafts, the moving plates 571 drive the fixed blocks 572 to be far away from the corresponding clamping plates 552 through the matching between the inclined surfaces of the moving plates 571 and the corresponding trapezoid blocks 584, the arc surfaces of the fixed blocks 572 are mutually matched with the arc sections of the metal rings along with the continuous movement of the trapezoid blocks 584, finally, the fixed blocks 572, the movable columns 570 and the clamping plates 552 in the annular areas of the same metal ring form a relatively fixed whole body through the continuous movement of the trapezoid blocks 584, the subsequent stretching acting force is convenient to be transmitted to the metal rings, the metal rings and the transverse shafts are enabled to be commonly subjected to stretching acting force, and meanwhile the stability of the clamped metal rings is further improved.
Clamping and limiting of the clamping part I55 and the clamping part II 56 on the metal rings are realized through the clamping and limiting parts between two groups of front and rear opposite L-shaped plates 540 in the two U-shaped frames 51 respectively corresponding to the left side and the right side of the bottom plate 1, so that four metal rings are arranged on each side of the anchor chain, the stability of stress at two ends of the anchor chain in the subsequent tensile strength experiment process is improved, and the stress at two ends of the anchor chain is uniform.
Fourth step: after both ends of the anchor chain are clamped and limited, the external hydraulic cylinder works to enable the lower pressing plate 591 to move downwards, downward pressure is applied to the sliding plate 50 through the lower pressing plate 591, one end of the sliding plate 50, far away from the bidirectional hydraulic cylinder 52, is tightly attached to the bottom plate 1, namely, balls 592 on the sliding plate 50 are kept in contact with the bottom plate 1, then the bidirectional hydraulic cylinder 52 works to enable two telescopic ends of the sliding plate to extend out, acting force far away from the bidirectional hydraulic cylinder 52 is applied to the two sliding plates 50, acting force of a set size for stretching the anchor chain is applied to both ends of the anchor chain through the sliding plate 50, whether the anchor chain is broken or not is observed, if the anchor chain is broken, the tensile strength is unqualified, otherwise, the tensile strength is qualified, and a tensile strength detection experiment on the anchor chain is completed.
Because the stretching force applied by the bidirectional hydraulic cylinder 52 is transmitted to the anchor chain through the U-shaped frame 51 and is not directly applied from the middle part of the anchor chain, the sliding plate 50 can only slide along the left and right directions by the downward pressing force of the pressing plate 591 on the sliding plate 50, so that the anchor chain is balanced when being subjected to the stretching force of the bidirectional hydraulic cylinder 52, the influence of the stretching force applied by the bidirectional hydraulic cylinder 52 on the stretching stress process of the anchor chain due to the fact that the position of the stretching force applied by the bidirectional hydraulic cylinder 52 is located below the anchor chain is reduced, and secondly, the bidirectional hydraulic cylinder 52 is arranged below the middle part of the anchor chain, and compared with the driving mode of respectively applying the stretching force from the two ends of the anchor chain, the occupied space of the device is reduced.
