[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, this utility model provides an elevator wire rope tension measuring device, including a rope tension meter 1 and a placement frame 2. A threaded knob 3 is threadedly connected internally to the placement frame 2, and a locking block 4 is rotatably connected to the end of the threaded knob 3. The device also includes:

[0025] Positioning components, which are disposed at both ends of the rope tension meter 1, are used to fix the rope tension meter 1 to the surface of the elevator wire rope;

[0026] The positioning component includes a first slot 5, which is located in the housing at both ends of the rope tension meter 1. A fixed shaft 6 is fixed inside the first slot 5. A first spring 7 and a movable frame 8 are sleeved on the outer surface of the fixed shaft 6. Fixed frames 9 are fixed at both ends of the bottom of the rope tension meter 1. A second slot 10 is opened inside the fixed frame 9. A second spring 11 and a movable part 12 are sleeved on the inner wall of the second slot 10. A limiting part 13 is fixed on one side of the movable part 12. Several sets of slots 14 are opened on the surface of the limiting part 13.

[0027] Through the cooperation between the movable part 12 and the second slot 10, the movable part 12 can move along the inner side of the second slot 10 and drive the limiting part 13 to move. At this time, the inclined surface of the slot 14 will lift the movable frame 8 until the limiting part 13 clamps the elevator wire rope. At this time, due to the elastic force of the first spring 7, the movable frame 8 will be driven to limit the limiting part 13, thereby limiting the two ends of the rope tension meter 1 to the wire rope. At this time, the locking block 4 can be stably controlled by the threaded knob 3 to lock the wire rope, which is convenient for detecting the tension of the wire rope.

[0028] like Figure 4 As shown, both ends of the movable frame 8 pass through the first slot 5 and extend to the outside of the first slot 5, and one end of the movable frame 8 is provided with a chamfer.

[0029] Through the design of the movable frame 8, since both ends of the movable frame 8 pass through the first slot 5, when one end of the movable frame 8 limits the limiting piece 13, the other end of the movable frame 8 can be pressed to control the movable frame 8 to separate from the clamping groove 14, so as to facilitate the taking out of the steel wire rope from the limiting piece 13 and the rope tension meter 1.

[0030] As shown in Figure 4 , 5 , the movable frame 8 is provided with a chamfered end which is movably connected with the clamping groove 14, the limiting piece 13 passes through the fixed frame 9, and the outer end of the limiting piece 13 is arc-shaped.

[0031] Through the cooperation between the movable frame 8 and the clamping groove 14, and the chamfered end of the movable frame 8, the one-way movement of the limiting piece 13 can be limited, so as to facilitate the locking of the elevator steel wire rope by the limiting piece 13.

[0032] As shown in Figure 2 , 5 , the limiting piece 13 is clamped with the steel wire rope in cooperation with the rope tension meter 1, and the second spring 11 is elastically supported between the second slot 10 and the movable piece 12.

[0033] Through the design of the second spring 11, the movable piece 12 has good elastic reset performance, at this time, since the second spring 11 is in a compressed state, a spring force is applied to the movable piece 12, so that the limiting piece 13 is automatically separated from the elevator steel wire rope when the movable frame 8 is separated from the clamping groove 14, facilitating the dismounting of the rope tension meter 1.

[0034] As shown in Figure 4 , the first spring 7 is elastically supported between the first slot 5 and the movable frame 8.

[0035] Through the design of the first spring 7, the movable frame 8 has good elastic reset performance, at this time, since the first spring 7 is in a compressed state, a spring force is applied to the movable frame 8, so as to drive the movable frame 8 to be connected with the limiting piece 13, facilitating the positioning of the limiting piece 13.

[0036] Working principle:

[0037] Firstly, the staff will contact both ends of the rope tension meter 1 with the elevator wire rope, then press the limiting piece 13, so that the movable piece 12 moves along the inner side of the second notch 10, at this time the inclined surface of the clamping groove 14 will lift the movable frame 8 until the limiting piece 13 clamps the elevator wire rope, at this time due to the elastic force of the first spring 7, it will drive the movable frame 8 to limit the limiting piece 13, so that both ends of the rope tension meter 1 limit the wire rope, then control the locking block 4 to lock the elevator wire rope through the threaded knob 3, after the detection of the tension of the elevator wire rope is completed, the staff can press the other end of the movable frame 8, so that the chamfer of the movable frame 8 is separated from the clamping groove 14, at this time the elastic force of the second spring 11 will push the limiting piece 13 out through the movable piece 12, so that the limiting piece 13 is separated from the rope tension meter 1, facilitating the disassembly of the rope tension meter 1.

[0038] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
