[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figure 1 shown, a wire rope tension dynamometer for elevator inspection and testing includes: a force measuring frame 1; a clamping mechanism 2 provided at both ends of the force measuring frame 1, the clamping mechanism 2 includes a first slideway 21 and a wedge block 22, and the wedge block 22 is slidably connected to the first slideway 21; a linkage mechanism 3 connecting the two wedge blocks 22; a detection mechanism 4 for detecting the tension of the wire rope; and a supporting mechanism 5 for supporting the wire rope, and the supporting mechanism 5 is slidably connected to the force measuring frame 1.

[0025] The force measuring frame 1 is a cuboid as a whole. When detecting the wire rope tension, the force measuring frame 1 is placed parallel to the wire rope. There is a handle on the force measuring frame 1, and the handle is held during use and combined with the wire rope.

[0026] As Figure 3 shown, the clamping mechanism 2 further includes a connecting block 23. The connecting block 23 is also wedge-shaped. The side surface of the connecting block 23 is connected to the force measuring frame 1, and the large end surface of the connecting block 23 is connected to the first slideway 21. There is a gap between the first slideway 21 and the connecting block 23, and both ends of the wire rope can enter the gap. As the inclined surface of the wire rope connecting block 23 changes, the gap gradually becomes smaller and clamps both ends of the wire rope.

[0027] The inclined surface of the wedge block 22 is parallel to the inclined surface of the connecting block 23. The small end surface of the wedge block 22 faces the large end surface of the connecting block 23. A slider is provided on the side of the wedge block 22, and the slider slides on the first slideway 21. When the wire rope is clamped by the first slideway 21 and the connecting block 23, the wedge block 22 is moved on the first slideway 21 to clamp the rear end of the wire rope, preventing the wire rope from moving backward during tension measurement and completely fixing the position of the wire rope.

[0028] The linkage mechanism 3 is used to simultaneously control the movement of the upper and lower wedge blocks 22, so as to facilitate the rapid fixation of the wire rope. The linkage mechanism 3 includes a connecting rod 31, an extension plate 32, an equipment plate 33, a first threaded rod 34 and a positioning nut 35. The connecting rod 31 connects the two wedge blocks 22, the connecting rod 31 is parallel to the force frame 1, the extension plate 32 is arranged in the middle of the connecting rod 31, the extension rod is perpendicular to the connecting rod 31, the equipment plate 33 is arranged in the middle of the force frame 1, the first threaded rod 34 penetrates the equipment plate 33, and the positioning nut 35 is screwed to the first threaded rod 34.

[0029] One end of the first threaded rod 34 is fixedly connected to the extension plate 32. A hole is provided on the device plate 33. The diameter of the hole is larger than the diameter of the first threaded rod 34. The first threaded rod 34 can move back and forth relative to the hole without rotating, so that the position of the wedge block 22 can be quickly adjusted. The positioning nut 35 is located at the end of the first threaded rod 34 away from the extension plate 32. The diameter of the positioning nut 35 is larger than the diameter of the hole. When the positioning nut 35 is in contact with the device plate 33, the first threaded rod 34 cannot move toward the extension plate 32. When in use, the first threaded rod 34 is pulled to make the wedge block 22 close to the wire rope, and then the positioning nut 35 is twisted to close the device plate 33, so that the first threaded rod 34 is fixed and positioned. After positioning, the device can be fixed on the wire rope, and the shaking generated during the tension test is reduced, thereby improving the efficiency of the detection.

[0030] The distance between the first threaded rod 34 and the force frame 1 is greater than the diameter of the wire rope. When the wire rope enters the clamping mechanism 2, the first threaded rod 34 will not hinder the route of the wire rope.

[0031] The detection mechanism 4 includes a tension sensor 41, a connecting shaft 42 and a second threaded rod 43. The second threaded rod 43 is screwed to the inner side of the equipment plate 33. The connecting shaft 42 is arranged behind the tension sensor 41. The front end of the second threaded rod 43 is rotatably connected to the connecting shaft 42. When the second threaded rod 43 rotates, the tension sensor 41 can be moved forward without rotating, and the rotation angle of the tension sensor 41 can also be manually adjusted. When the wire rope is fixed, the second threaded rod 43 is rotated to push the connecting shaft 42 and the tension sensor 41 to push the wire rope to generate tension.

[0032] A display screen 11 is provided on the force measuring frame 1 , and the display screen 11 is signal-connected to the tension sensor 41 , so that the display screen 11 displays tension data.

[0033] like Figure 2As shown in the figure, the supporting mechanism 5 includes a support plate 51, a second slideway 52, a reaction plate 53 and a third threaded rod 54. The support plate 51 is arranged behind the steel wire rope. The support plate 51 is slidably connected to the second slideway 52. The reaction plate 53 is arranged at the rear end of the second slideway 52. The third threaded rod 54 is screwed to the reaction plate 53. The third threaded rod 54 is in contact with the rear end of the support plate 51. The second slideway 52 protrudes from the side wall of the force measuring frame 1. A scale line 521 is arranged on the side of the second slideway 52. The moving distance of the steel wire rope is recorded by controlling the position of the support plate 51. The rear end position of the support plate 51 is controlled by rotating the third threaded rod 54. After the tension sensor 41 pushes the steel wire rope to the support plate 51, the support plate 51 restricts the continuous movement of the steel wire rope. At this time, the position and tension of the support plate 51 can be recorded.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
