Detailed Description

The present invention will be further described with reference to the following examples, which are not intended as a limitation to the present invention.

Example (b): the utility model provides an install disconnected rope detection device of wire rope additional, constitutes as shown in fig. 1 to 3, including setting up fixed bolster 10 and the detection support 20 in fag end subassembly both sides respectively, fixed bolster 10 horizontal rotation is connected with apron 30, and the lower surface and the fag end subassembly contact of apron 30, be equipped with on the detection support 20 with apron 30 expansion end complex detection switch 21. The fixing bracket 10 is provided with a vertical long waist hole 11, a rotating shaft 31 of the cover plate 30 penetrates through the long waist hole 11, and a shaft seat 32 for adjusting the height of the rotating shaft 31 relative to the long waist hole 11 is sleeved on the rotating shaft 31.

The shaft seat 32 comprises a cylindrical seat body, the outer surface of the seat body is respectively provided with a pair of sliding chord tangent planes 33 and a pair of locking chord tangent planes 34, the sliding chord tangent planes 33 are in clearance fit with the long waist hole 11, and the locking chord tangent planes 34 are in interference fit with the long waist hole 11. The outer surface of the base body is also provided with a handle 35, and the axis of the handle 35 is parallel to the locking tangential plane 34. And a rubber pad 12 is arranged on the side wall of the long waist hole 11.

The fixing support 10 comprises angle iron arranged on an elevator beam, a vertical plate 13 is arranged on the angle iron, and the long waist hole 11 is arranged on the vertical plate 13. The detection support 20 comprises angle iron arranged on an elevator beam, and a stand column 22 for fixing the detection switch 21 is arranged on the angle iron.

As shown in fig. 1, the fixing bracket 10 and the detecting bracket 20 are fixed to the elevator beam by a pressing plate 40. Here, the elevator beam is also the mounting place of the rope head assembly, specifically, a car rope head channel in fig. 1, or a hoistway elevator upper beam, etc.

The working principle is as follows:

as shown in fig. 1, the rope end channel and the rope end assembly are both assembled or installed structures. The utility model discloses utilize clamp plate 40 two angle steels of both sides installation of fag end subassembly on the fag end channel-section steel, fixed riser 13 on the angle steel of one side, riser 13 level is rotated and is connected apron 30, fixed root post 22 on the angle steel of opposite side, sets up a detection switch 21 on the stand 22, also is the UKS switch. In a normal state, one end of the cover plate 30 is rotatably fixed on the vertical plate 13, the middle of the cover plate 30 is in contact with the upper end of the rope assembly, and the other end of the cover plate is in contact with the UKS switch. These three points form a lever structure on the cover plate 30. In emergency, the steel wire rope is broken, the stress of other steel wire ropes is increased, the compression degree of the spring on the rope head assembly is increased, and the upper end of the rope head assembly moves downwards. Because the supporting force of the middle part is weakened or disappeared, the cover plate 30 rotates a certain angle around the rotating shaft 31, the UKS switch which is in contact with the movable end of the cover plate 30 is triggered, and the UKS switch is connected into a safety circuit of the elevator, so that the rope breakage protection is realized.

When the shaft seat 32 is adjusted, the two sliding tangent planes 33 are limited to slide in the long waist hole 11. After the sliding is performed to the target height, the base body is rotated by the handle 35, the handle 35 is rotated to the vertical position, and at the moment, the two locking chord sections 34 are in interference fit with the long waist hole 11 to realize locking. The rubber pad 12 is adhered to the inner wall of the long waist hole 11, so that friction force can be increased, locking performance is improved, and even if the rubber pad 12 is aged, the height of the shaft seat 32 is kept by a depression generated at the extruded part. The mounting hole for mounting the UKS switch on the column 22 is also a kidney-shaped hole, and the height of the UKS switch can be appropriately adjusted. Both of these adjustments are made at the time of installation to accommodate different head assembly heights for different elevators.
