Description

Technical Field

[0001] The present invention relates to the technical field related to elevator operation detection, and in particular to a stability detection device for elevator trial operation. Background Art

[0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin, used to carry people or goods in multi-story buildings. There are also stepped types, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways. It is a fixed lifting device that serves specified floors. A vertical elevator has a car that runs between at least two rows of vertical rigid guide rails. Before the elevator is delivered, testers are required to use a detection device to test the smoothness of the elevator's operation. If the operation is not smooth, it needs to be re-debugged. Most existing detection devices are equipped with acceleration sensors and vibration sensors to detect smoothness. Although this method has high data accuracy, the device cost is also high. Most smoothness tests only require testers to know whether the elevator is running smoothly, and there is no need to use these high-cost devices to obtain high-precision data. For this reason, those skilled in the art have proposed a smoothness detection device for elevator trial operation to solve the problems raised in the above background. Summary of the Invention

[0007] As a further solution of the present invention: the clamping assembly includes a fixed cylinder, a movable rod and a clamping frame, one end of the fixed cylinder is installed on the inner wall of the vacuum detection box, one end of the movable rod is interlaced and connected with the other end of the fixed cylinder, the other end of the movable rod is connected to the outer wall of the clamping frame, and a fixing bolt is installed on the outer wall of the other end of the fixed cylinder.

[0008] As a further solution of the present invention: an air extraction port is provided in the middle of the box cover, and the edge of the box cover is fixed to the top edge of the vacuum detection box by mounting bolts.

[0009] As a further solution of the present invention: an annular protrusion is provided on the top of the vacuum detection box, an annular groove is provided at the bottom end of the edge of the box cover to cooperate with the annular protrusion, and a sealing sleeve is provided on the periphery of the annular protrusion.

[0010] As a further solution of the present invention: a plurality of reinforcing rods are provided inside the vacuum detection box, and two ends of the reinforcing rods are respectively fixedly connected to the inner walls on both sides of the vacuum detection box.

[0011] The present invention has the following advantages: the detection device detects the smoothness of elevator operation by cooperating with a counterweight, an elastic member, a pressure sensor, a laser emitter, and a marking plate. A qualified elevator decelerates slowly from operation to stop and does not brake suddenly. The counterweight is placed in the inner cavity of a vacuum detection chamber under a vacuum environment. If the elevator brakes suddenly, the acceleration of the counterweight will change greatly in a short period of time. At the same time, the counterweight will press the pressure sensor under this huge acceleration change. By detecting the value change of the pressure sensor, it can be inferred whether the elevator is running smoothly. Pressure sensors are provided above and below the counterweight, which can detect the upward and downward movement of the elevator. The detection function is complete. At the same time, the laser emitter's irradiation point can be marked by the marking plate. When the laser has a large deviation, it can reflect the unevenness of the elevator operation. If the laser irradiation point has a horizontal deviation, it can reflect the horizontal shaking of the elevator during operation. The overall structure of the device is simple and easy to operate, with low structural cost. The bottom plate is provided for easy movement, which has greater practicality.

[0025] Working principle: When in use, the stability of the elevator from running to stopping is tested. When the elevator brakes suddenly, the counterweight 9 squeezes the elastic part 10 due to inertia, and the elastic part 10 squeezes the pressure sensor 8. The value of the pressure sensor 8 can intuitively reflect the magnitude of the short-term inertial force of the counterweight 9. If the pressure detected by the pressure sensor 8 is large, it means that the elevator brakes suddenly, which proves that the elevator is less stable. At the same time, the counterweight 9 will drive the laser emitter 11 to move synchronously. If the position of the laser irradiation point on the marking plate 12 has a large offset, or the offset time is very short, it means that the elevator operation stability is poor. If the laser irradiation point has an offset in the horizontal direction, it means that the elevator shakes during operation.
