Description

Technical Field

[0001] The utility model relates to the technical field of elevator detection, in particular to an elevator braking capacity detection device. Background Art

[0002] During the operation of the elevator, it is often necessary to measure data such as the elevator's running speed, running distance and braking distance to determine the elevator's operating status. The elevator brake detection device is a device that can detect whether the elevator's braking ability is qualified. The device consists of a detection handheld terminal and a front-end wheel. During the detection, the front-end wheel is rotated close to the wire rope, and the wire rope drives the front-end wheel to rotate to perform the detection operation.

[0003] A Chinese patent with announcement number CN219301970U discloses an elevator braking capacity detection device, including a shell, a measuring wheel is fixedly connected to one side of the upper end of the shell, a slide groove is provided on the other side of the upper end of the shell, a threaded rod is provided inside the slide groove, a slider is slidably connected to one end of the threaded rod, a torque wrench is fixedly connected to the other end of the threaded rod, an extrusion wheel is fixedly connected to the upper surface of the slider, anti-sliding blocks are fixedly connected to the outer surfaces of the measuring wheel and the extrusion wheel, and mounting blocks are fixedly connected to both sides of the outer surface of the shell. In the utility model, by placing the steel cable on the outer surface of the measuring wheel and then twisting the torque wrench to drive the extrusion wheel to move through the threaded rod, the steel cable can be clamped under the cooperation of the extrusion wheel and the measuring wheel, so that the friction between the measuring wheel and the steel wire rope can be the same, thereby improving the measurement accuracy. However, the above patent adopts a manually adjusted extrusion wheel to brake the steel wire rope. This support braking method not only consumes a lot of physical strength of the workers, but also takes a long time to use. At the same time, during the detection process, it is easy to cause certain errors in the detection results due to untimely braking, thereby reducing the accuracy of the device. For this reason, we propose an elevator braking capacity detection device to solve the above problems. Utility Model Content
