[0013] The utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 As shown, a wire rope cutting device for a cage door of an elevator of the utility model comprises a clamping mechanism 2 of a wire rope receiving groove 1. The wire rope receiving groove 1 is made of channel steel, and the wire rope to be cut is placed inside, which is conducive to limiting the position of the wire rope. On the wire rope receiving groove 1, three groups of shearing areas are symmetrically opened in the length direction of both sides with the middle point as the center, namely the first group of shearing areas 3, the second group of shearing areas 4 and the third group of shearing areas 5. Each group has two shearing areas, wherein the distance from each shearing area to the farther end of the wire rope receiving groove is a fixed shearing distance or shearing length, which is used for the production of cage door wire rope. Among them, the distance from one of the shearing areas of the first group of shearing areas 3 to the farther end of the wire rope receiving groove 1 is 2.55 meters, the distance from one of the shearing areas of the second group of shearing areas 4 to the farther end of the wire rope receiving groove 1 is 2.85 meters, and the distance from one of the shearing areas of the third group of shearing areas 5 to the farther end of the wire rope receiving groove 1 is 2.95 meters. Mounting holes 16 are provided on the center lines of both ends of the wire rope accommodating groove 1.

[0015] The clamping mechanism 2 includes a rectangular pressing plate 21 and bolts and nuts. A mounting hole II7 is provided in the center of the rectangular pressing plate 21. The clamping mechanism can be installed at either end of the wire rope receiving groove 1. During installation, the bolts pass through the mounting holes I6 and II7 from the bottom in sequence, and the upper end is connected with nuts. Between the rectangular pressing plate 21 and the bottom plate of the wire rope receiving groove, two wire rope clamping areas are formed on both sides with the bolts as the center line. During shearing, the ends of the two wire ropes are placed in the two wire rope clamping areas at the same time, and the ends of the wire ropes are clamped and fixed with the rectangular pressing plate 21 by tightening the nuts.

[0016] Each shearing area has two symmetrical slots. For example, the first shearing area 3 has two symmetrical slots 31. When shearing, the hydraulic pliers are used to shear from the side of the slot 31, and both wire ropes are cut into 2.55 meters. Of course, if one is cut into 2.55 meters, the other can also be cut into 2.85 meters or 2.95 meters as needed. The three lengths of wire ropes after cutting are used for the counterweight connection of the elevator cage door.

[0017] Since the three groups of shearing areas are symmetrically arranged, the clamping mechanism 2 can also be installed at any end of the wire rope accommodating groove 1. Therefore, it is quite convenient for the staff to operate.

[0018] In addition, a support base 8 is provided at the bottom of the wire rope accommodating groove 1 .

[0019] Of course, the wire rope shearing device of the utility model is not only used for shearing wire ropes of elevator cage doors, but can also be used for shearing fixed-length wire ropes of other industries, and has a wide range of applications.

[0020] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Various changes that can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention are all within the protection scope of the claims of the present invention.
