[0002] Life goes on, technology develops, and elevators are also making progress. In the past 150 years, the materials of elevators have changed from black and white to colorful, and the styles have changed from straight to inclined. In terms of operation and control, there have been continuous innovations - handle switch operation, button control, signal control, collective selective control, man-machine dialogue, etc. For multiple elevators, parallel control and intelligent group control have emerged; double-deck car elevators demonstrate the advantages of saving hoistway space and improving transportation capacity; the emergence of variable-speed automatic sidewalk escalators has greatly saved pedestrians' time; sightseeing elevators with different shapes - fan-shaped, triangular, semi-rhombic, semi-circular, and full-circular - no longer confine the vision of passengers inside.

[0003] While elevators improve the living standards of humans, the safety of elevator devices should also be an issue that cannot be ignored. Therefore, all elevators are equipped with system operation protection devices. The elevator tensioning device is one of the safety control components in the elevator safety protection system. However, the shield of the tensioning device in the prior art is of an integral structure, and separate holes need to be made on the shield to adapt to different rope wheel diameters.

[0008] A rear cover plate, which is fixedly connected to the beam for fixing the rope wheel. A rotating shaft of the rope wheel is provided on the rear cover plate, and the rope wheel is arranged on the rotating shaft;

[0009] A front cover plate, which covers the side of the rope wheel away from the rear cover plate, and the front cover plate is fixedly connected to the rear cover plate;

[0010] Shoulder covers, which are inclined. The shoulder covers are arranged at the positions for the rope to pass between the front cover plate and the rear cover plate. There are two shoulder covers, and the shoulder covers are respectively detachably connected to the front cover plate and the rear cover plate.

[0011] Further, a front connecting plate and a rear connecting plate are arranged on the shoulder cover. The front connecting plate is arranged at one end of the shoulder cover close to the front cover plate, and the rear connecting plate is arranged at one end of the shoulder cover close to the rear cover plate.

[0012] Further, connecting holes are arranged on both the front connecting plate and the rear connecting plate, and mounting holes are arranged at positions corresponding to the connecting holes on the front cover plate and the rear cover plate.

[0013] Further, a front top plate is arranged at the top of the front cover plate, and a rear top plate is arranged at the top of the rear cover plate. Both the front top plate and the rear top plate cover the top of the rope pulley.

[0014] Further, the tops of the two shoulder covers are respectively connected to the front top plate and the rear top plate by bolts.

[0015] Further, a strip-shaped through hole for the rope to pass through is arranged on the shoulder cover.

[0016] It can be seen from the above technical solutions that, compared with the prior art, the present utility model discloses an elevator tensioning device shield. By providing a shoulder cover and detachably connecting the shoulder cover to the front cover plate and the rear cover plate, the front cover plate and the rear cover plate can be installed first when installing the rope pulley, and then the shoulder cover can be designed and replaced according to the sizes of the rope and the rope pulley, so that the tensioning device shield can be applicable to a variety of use occasions and rope pulleys and ropes of various sizes.
