Description of the embodiments
The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.
A rope breakage protection device for an elevator is provided with a protection switch 3 and a striker 41 on a rope end fixing plate 1. The specific structure is as follows: as shown in fig. 1, the rope end assembly is mounted on a rope end fixing plate 11, a rope end spring 12, a rope end nut 13 and a rope end pull rod 14 are arranged above the rope end fixing plate, the rope end pull rod penetrates through the rope end fixing plate, and a rope end sleeve 15 is connected below the rope end pull rod. The rope end fixing plate is bent to form a rope end transverse plate 111 and a rope end vertical plate 112, a switch fixing bracket 2 is arranged on the rope end vertical plate, and the protection switch is connected to the switch fixing bracket; the rope head transverse plate is elastically connected with a bumping bow bracket 42 through a bumping bow tension spring 6, the bumping bow 41 is fixed on the bumping bow bracket, and the bumping bow bracket is movably connected on the rope head transverse plate. The switch fixing support and the bow-striking support are both positioned above the rope head sleeve, and the rope head transverse plate, the switch fixing support, the bow-striking support and the rope head sleeve are sequentially arranged from top to bottom. The striking bow comprises a connecting rod 411 and a trigger rod 412, wherein the connecting rod is fixed on a striking bow bracket, and the trigger rod is bent upwards to be close to a contact point of the protection switch.
The bow-striking support is movably connected on the rope head transverse plate, can be in sliding connection, can be in elastic connection and can even be in rotary connection. Considering the autorotation caused by the gravity influence of the bow-striking bracket, the structure can be complicated, and the embodiment adopts elastic connection. The preferable proposal is that the two sides of the rope head transverse plate are provided with the bow-striking tension springs, and the two ends of the bow-striking tension springs are elastically hung with the bow-striking bracket. The bow-striking support is provided with a through hole, and the rope head pull rod passes through the through hole of the bow-striking support. An adjusting screw 61 is arranged in the middle of the bow-striking tension spring, the adjusting screw penetrates through the bow-striking bracket, and an adjusting nut 62 is arranged at the bottom of the bow-striking bracket. The height of the bow-striking bracket is adjusted through the adjusting nut, so that the trigger rod is upwards bent to be close to the contact of the protection switch, and misoperation is avoided. Meanwhile, the bow-striking tension spring has certain tension, the bow-striking bracket cannot shake randomly, and misoperation is avoided.
Due to the dead weight of the bow-striking bracket, the bow-striking bracket is positioned at the lowest end of the sliding rail in normal operation, and the bow-striking bracket opens the protection switch through upward displacement when the rope is broken.
When the elevator normally operates, the rope end nut compresses the rope end spring, the tension of the steel wire rope is increased, and the steel wire rope is in a tensioning state. When the steel wire rope breaks or breaks away from the rope head combination, the rope head spring receives the restoring elastic force to stretch and jack up the rope head nut, so that the rope head pull rod and the rope head sleeve are driven to rapidly rise, the rope head sleeve impacts the collision bow, the collision bow moves upwards, the protection switch is opened, and the operation of the elevator is stopped.
The optimal design of the protection switch is that the rope head fixing plate is arranged at the side edge of the guide rail 5 of the elevator and is close to the upper limit travel switch, the upper limit travel switch is used as the protection switch 3 for rope breakage, namely, the protection switch on the rope head vertical plate forms a travel switch needed above the guide rail of the elevator. When the elevator runs at the upper limit, the guide shoe or other parts drive the bow-striking bracket to move upwards, the protection switch is turned on, and the elevator stops running.
