Description

Elevator buffering reset performance detection device

Technical Field

The utility model relates to the technical field of elevator buffer reset performance detection, in particular to an elevator buffer reset performance detection device.

Background

An elevator buffer is a very important safety component of an elevator, and is usually arranged at the bottom of the travel of an elevator car and a counterweight device, when the elevator exceeds a bottom layer or a top layer, the car or the counterweight impacts the buffer, and the buffer absorbs or consumes the kinetic energy of the elevator, so that the car or the counterweight is safely decelerated until stopping.

There are two main forms of existing buffers for elevators: energy-storage type buffer and energy-consumption type buffer. The energy storage type buffer is only suitable for elevators with the speed of less than 1m/s, the hydraulic buffer is suitable for any type of elevator, and under the condition of the same use condition, the stroke required by the hydraulic buffer is reduced by half compared with that of a spring buffer, so that the hydraulic buffer can be more protected for personnel and equipment in the operation of the elevator, therefore, passengers often use the hydraulic buffer, and the safety performance of the hydraulic buffer can be influenced by a plurality of factors such as the compression stroke length, the reset time and whether the reset process of the hydraulic buffer has blocking or not, so that hidden danger can be found in advance for daily maintenance and detection of the buffer, the working reliability of the hydraulic buffer is guaranteed, and the safety of the elevator is important.

The traditional method for measuring the reset of the hydraulic buffer is mainly a manual operation mode, but when the reset time of the elevator buffer is detected, if an inspector does not squat at the pit bottom for detection, the actual compression formation of the buffer cannot be measured, and whether the buffer has a blocking phenomenon in the compression and reset process cannot be known; if people squat in the pit to observe and time, on one hand, the pit environment is poor and the buffer is dangerous when being fully compressed; on the other hand, the subjectivity of manual timing is large, when the detection is carried out, a inspector monitors the compression buffer of the car outside a hall or in a machine room, then the resetting process of the buffer is timed, so that the time when the car is lifted, the time when the buffer is reset is difficult to accurately judge, the actual compression stroke of the buffer is what, the dynamic characteristics of 'full compression' and 'car lifting moment' required by regulations are only subjectively confirmed, and related data cannot be measured rapidly, reliably and accurately, so that various problems of large measurement human factors, low measurement precision, large result dispersion, low detection efficiency and the like of the buffer resetting time are caused, the safety performance condition of the buffer cannot be reflected comprehensively in time, and the safe operation of elevator equipment cannot be effectively ensured.

Therefore, the utility model provides an elevator buffer reset performance detection device.
