[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] See also Figure 1-5 As shown, a tensile testing device for wire rope production includes a test base 1, a rubber pad is provided at the bottom of the test base 1, a slide groove 2 is provided above the test base 1, a drive seat 3 is provided in the slide groove 2, and a group of wire positioning mechanisms are respectively provided on the upper side of the test base 1 and on the drive seat 3; the wire positioning mechanism is used to position the wire rope to be tested for tensile strength, avoiding the traditional method of fixing the wire rope by hooking. Due to the notch above the hook, when the tension is too large during the pulling process of the wire rope, the wire rope may slip out of the notch, affecting the normal progress of the wire rope test.

[0026] The two wire positioning mechanisms are symmetrically arranged. A support platform 4 is arranged above the other side of the test base 1. A reduction motor 5 is arranged on the support platform 4. The torque of the reduction motor 5 is large, so that the pull rope 21 is pulled stably, and then the wire rope is tensile tested. A winding groove wheel 6 is arranged on the output end of the reduction motor 5, and a bracket 7 is arranged on the test base 1. The bracket 7 is located between the slide 2 and the support platform 4. An auxiliary groove wheel 8 is arranged on the bracket 7. When working, the winding groove wheel 6 is rotated by the operation of the reduction motor 5, so that the pull rope 21 is wound on the winding groove wheel 6 through the auxiliary groove wheel 8, and then the wire positioning mechanism on the drive seat 3 is pulled, so that the wire rope between the two wire positioning mechanisms is tensile tested.

[0027] Further, such as Figure 1 、 2 As shown, the wire positioning mechanism includes a mounting seat 9, a support 10 is provided above the mounting seat 9, a positioning cylinder 11 is fixedly provided on the support 10, a positioning column 12 is provided in the middle of the positioning cylinder 11, a column groove 13 is provided on the positioning column 12, a rope groove 14 is provided on the side of the positioning cylinder 11, a cylinder cover 15 is detachably provided above the positioning cylinder 11, and a plug column 16 is provided below the cylinder cover 15, and the plug column 16 is inserted in the column groove 13. When working, the end of the wire rope to be tested is fixed into a ring shape, the end of the wire rope is sleeved on the positioning column 12 in the corresponding positioning cylinder 11, and then the wire rope is passed through the rope groove 14, the cylinder cover 15 is installed on the positioning cylinder 11 by screws, and the plug column 16 is inserted in the corresponding column groove 13, so that the end of the wire rope to be tested can be effectively positioned.

[0028] Further, such as Figure 1 As shown, a rope groove 14 is provided on the side of the positioning cylinder 11, and a lower rope guide plate 17 is fixedly provided on the rope groove 14. An upper rope guide plate 18 is detachably provided on the lower rope guide plate 17. The wire rope is placed on the lower rope guide plate 17, and then the lower rope guide plate 17 and the upper rope guide plate 18 are positioned by screws. Through this structural setting, the wire rope can be limited to avoid shaking of the end of the wire rope when the wire rope is subjected to a tensile test.

[0029] Further, such as Figure 1 、 2 As shown, a reinforcing plate 19 is provided on the mounting seat 9 and the support 10 , and the reinforcing plate 19 improves the structural integrity of the mounting seat 9 and the support 10 .

[0030] Further, such as Figure 1 、 4 As shown, a tension sensor 20 is provided on the support 10 on the drive seat 3, and a pull rope 21 is provided on one side of the tension sensor 20. The pull rope 21 passes through the auxiliary groove wheel 8 and is wound on the winding groove wheel 6. The tension sensor 20 uses two tension transmission parts to transmit force. Its structure contains a force-sensitive device and two tension transmission parts. The force-sensitive device contains a piezoelectric piece and a piezoelectric piece gasket. The latter contains a substrate part and an edge force transmission part. Under the action of external force, elastic deformation occurs, and the piezoelectric piece is deformed. After the piezoelectric piece is deformed, its resistance value will change. The corresponding measuring circuit converts this resistance change into an electrical signal, thereby completing the conversion of the external force into an electrical signal, thereby controlling the tension of the reduction motor 5 to pull the pull rope 21.

[0031] Further, such as Figure 1 、 4As shown in FIG5 , the middle parts of the tension sensor 20 , the auxiliary sheave 8 and the retracting sheave 6 are on the same plane, so as to avoid a large deviation of the force line when the wire positioning mechanism on the drive seat 3 is pulled.

[0032] During operation, the steel wire rope to be tested is positioned by the structural setting of the steel wire positioning mechanism, avoiding the traditional method of fixing the steel wire rope by hooking. When the tension is too large, the steel wire rope may be unhooked, affecting the normal progress of the steel wire rope test. The end of the steel wire rope to be tested is fixed into a ring shape, the end of the steel wire rope is sleeved on the positioning column 12 in the corresponding positioning cylinder 11, and then the steel wire rope is passed through the rope groove 14. The cylinder cover 15 is installed on the positioning cylinder 11 by screws, and the plug column 16 is inserted into the corresponding column groove 13, so that the steel wire rope to be tested is positioned. The end portion is effectively positioned, the wire rope is placed on the lower rope guide plate 17, and then the lower rope guide plate 17 and the upper rope guide plate 18 are positioned by screws. Through this structural setting, the wire rope can be limited to avoid the end portion of the wire rope from shaking when the wire rope is subjected to a tensile test. Through the operation of the reduction motor 5, the winding groove wheel 6 is rotated, so that the pull rope 21 is wound on the winding groove wheel 6 through the auxiliary groove wheel 8, and then the wire positioning mechanism on the drive seat 3 is pulled, so that the wire rope between the two wire positioning mechanisms is subjected to a tensile test.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
