Description
Technical Field
The utility model belongs to the technical field of elevator stopper and specifically relates to an elevator stopper braking force early warning device is related to.
Background
In recent years, elevator safety accidents caused by insufficient braking force of a plurality of elevator brakes are caused, and huge losses are brought to life and property of people. The elevator brake is an important part for the elevator to stop reliably, and if the brake is in trouble, the elevator can have serious safety accidents. The braking force is used as an important performance parameter of the brake, so that whether elevator maintenance personnel or elevator inspection personnel work in daily life, the elevator maintenance personnel or the elevator inspection personnel are difficult to visually check and judge, and if the elevator maintenance personnel or the elevator inspection personnel do not check in place, the elevator safety accident can be caused. In 2019, 700 thousands of elevators exist in China, wherein old elevators account for more than half of the total amount, and part of brakes even cannot meet the requirements of the current standard, which are potential hazards, and if the braking force of the elevator brake is effectively and visually monitored, the safety accidents caused by the brake can be greatly reduced. Until now, no early warning device for visually judging the insufficient braking force of the elevator brake exists in the market. In a modification list No. 2 of TSG T7001-2009 elevator supervision inspection and regular inspection rules, namely traction and forced driving of an elevator, when a car accidental movement protection device test is carried out, if the braking force of an internal redundant brake is insufficient, the elevator cannot be started normally. However, the braking force is insufficient, and the detection rule is not clearly specified, so that the insufficient braking force of the brake cannot be objectively and accurately judged during the detection. The prior art does not have a braking force early warning device for an elevator brake, whether the braking force meets the requirement or not, and the elevator brake can only be inspected through the daily maintenance of elevator maintenance personnel or during the inspection of elevator inspection personnel. Elevator maintenance personnel maintain the elevator once every 15 days, and do not check the braking force of an elevator brake every time; the elevator is tested once a year, and the testing time interval of the braking force of the brake of the elevator is too long.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the problem that the prior art has long inspection period of the braking force of the elevator and does not have the braking force early warning device specially for the elevator brake, and provides the braking force early warning device for the elevator brake.
The above technical problem of the present invention can be solved by the following technical solutions: the braking force early warning device for the elevator brake comprises a braking distance detection module, a data transmission module and a data processing module, wherein the data processing module comprises a threshold value comparison unit, a data calculation unit and an early warning unit, and the braking distance detection module, the data transmission module, the data calculation unit, the threshold value comparison unit and the alarm unit are electrically connected in sequence.
The utility model relates to an elevator stopper braking force early warning device, braking distance detection module installs at the car top, go upward when braking experiment, detect out the relevant speed data of car through braking distance detection module, this speed data information passes through data transmission module and transmits to installing data processing module in elevator computer lab or elevator switch board, data computing unit in the data processing module calculates the last braking distance of elevator and will go upward braking distance numerical value and send threshold value contrast unit through received speed data, threshold value contrast unit says that the last braking distance information that receives compares with preset's last braking distance threshold value, judge whether the braking force of elevator meets the requirements, record numerical value at every turn simultaneously, contrast, know the trend of change of elevator braking force. If the braking force does not meet the requirement, the alarm unit sends out a warning signal in time. The uplink braking distance is in the range of a standard TCASEI _ T102-2015 rapid detection method for braking capacity of a traction drive elevator, the braking force is in accordance with the requirement, and if the braking distance exceeds the standard range, the braking force is in accordance with the requirement. The device measures the upward braking distance of the elevator car according to the principle, so as to obtain whether the braking force of the elevator meets the requirement.
Preferably, the braking distance detection module is an acceleration and deceleration sensor.
As a preferred scheme, the data transmission module is bluetooth.
Therefore, the utility model has the advantages that: the device can know whether the braking force of the brake of the elevator meets the requirement only by carrying out one-time upward braking power-pulling test on the elevator, and is simple to operate. Meanwhile, the device is simple in structure and convenient to install. The device is completely independent with elevator control system, need not change switch board circuit and control mode, need not handle the construction procedure, and is practical and not loaded down with trivial details, can effectively monitor elevator brake's braking force, fault rate and incident incidence that greatly reduced elevator brake arouses.
