Technical Field

[0001] The utility model relates to the technical field of elevator safety protection devices, and more specifically to a slide rail type elevator tensioning device. Background Art

[0002] The tensioner is one of the safety control components in the elevator safety protection system. When the elevator car is overspeeding or even in danger of falling for any reason during operation, and all other safety protection devices are ineffective, the tensioner will work in conjunction with other components to stop the elevator car. In the prior art, the elevator tensioner consists of a large rope wheel and a large counterweight. When in use, the tensioner will drive the rope to swing, which will seriously affect the safety of the elevator.

[0003] Therefore, how to provide a slide rail type elevator tensioning device that can prevent the tensioning rope from swinging and can effectively tighten the rope is a problem that those skilled in the art need to solve urgently. Utility Model Content

[0004] In view of this, the utility model provides a slide rail type elevator tensioning device, which aims to solve the problems in the above-mentioned background technology, prevent the rope used for tensioning from swinging and can effectively tighten the rope.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A slide rail elevator tensioning device, comprising:

[0007] A vertical slide rail, the side wall and the bottom of which are connected to the main structure;

[0008] A vertical slide is slidably connected to the vertical slide rail, and a rope wheel is hinged on the vertical slide, and the rope wheel tightens the rope.

[0009] Furthermore, the vertical slide rail includes a left rail and a right rail, and the left rail and the right rail are respectively arranged on two sides of the vertical slide frame.

[0010] Furthermore, the vertical slide includes a square box and a pulley, and a plurality of pulleys are provided. The plurality of pulleys are respectively arranged on both sides of the square box and are rotatably connected to the square box, and the plurality of pulleys roll on the left track and the right track respectively.

[0011] Furthermore, the rope pulley is arranged on the top of the square box and is hinged to the square box. A wheel cover is arranged on the top of the rope pulley, and the wheel cover is fixedly connected to the square box.

[0012] Further, an upper instantaneous switch and a lower instantaneous switch are arranged on the left track, and a pressing plate is arranged on the vertical sliding frame. The pressing plate is arranged on the side of the vertical sliding frame close to the left track. When the vertical sliding frame slides to the uppermost position, the pressing plate pushes the upper instantaneous switch. When the vertical sliding frame slides to the lowermost position, the pressing plate pushes the lower instantaneous switch.

[0013] Further, a counterweight is arranged at the bottom of the square box body, and a plurality of counterweights are arranged.

[0014] Further, a receiving block is arranged at the bottom of the counterweight. The receiving block is used to support the counterweight, and both ends of the receiving block are fixedly connected to the lower bottom of the square box body.

[0015] As can be seen from the above technical solutions, compared with the prior art, the present utility model discloses a sliding rail type elevator tensioning device. By arranging a vertical sliding rail and a vertical sliding frame, and arranging a rope wheel on the vertical sliding frame, it can be realized that the rope wheel slides vertically during the up and down movement of the vertical sliding frame. During the vertical sliding of the rope wheel, the rope wheel will tension the rope. Since the rope wheel only moves up and down without swinging, it can effectively prevent the rope from swinging and effectively improve the safety of the elevator. Description of the Drawings
