Abstract
The utility model discloses a testing device for resetting of a hydraulic buffer of an elevator. The testing device comprises a master controller, a distance measuring module and a pressure detection module, wherein the distance measuring module and the pressure detection module are connected with the master controller and are controlled by the master controller. According to the testing device, a display device is separated from the testing device, so that inspection personnel can be far away from a measuring field, and the testing device is safe and reliable; meanwhile, ultrasonic wave is used as a distance measuring medium, so that high measuring accuracy is realized; and measurement data is calculated by using the master controller, so that the result is scientific and accurate.
Description
Technical field
The utility model relates to proving installation, relates in particular to the proving installation that a kind of elevator water bumper resets, and is used for the elevator detection field.
Background technology
The use of elevator concerns passenger's life security, therefore needs to detect on time.In the elevator testing process, there is at present quite a few Interventions Requested to lack measuring means necessary, science, such as the hydraulic buffer test for the 8.2nd regulation of ESG-T7001-2009 " elevator supervision and inspection and periodical survey rule-traction and forcibly driving elevator ", the detection means that adopts at present, subjectivity is large, assay does not have science, accuracy, and has certain danger for the inspector.
The utility model content
The utility model is for solving the prior art problem, and a kind of safe, elevator water bumper reset test device accurately is provided.
The technical solution of the utility model is: the proving installation that a kind of elevator water bumper resets, comprise master controller, and be connected with this master controller and be subjected to range finder module and the pressure detection module of this main controller controls.
As preferably, described range finder module is ultrasonic range finder.
As preferably, described ultrasonic range finder comprises ultrasonic transmitter and the ultrasonic receiving device that is connected with described master controller and cooperatively interacts respectively.
As preferably, be connected by signal generation apparatus between described ultrasonic transmitter and the described master controller.
As preferably, described signal generation apparatus is 555 circuit.
As preferably, described proving installation also comprises input/output unit and the read out instrument that is connected with described master controller respectively.
As preferably, described input/output unit is connected with described master controller by wireless signal with read out instrument.
As preferably, described range finder module is connected with described master controller by wireless signal.
In sum, the utlity model has following advantage:
1, adopt read out instrument and measurement mechanism separate design, so that the inspector can be away from measure field, safe and reliable;
2, adopt super sonic as the range finding medium, survey precision is high, adopts simultaneously master controller computation and measurement data, as a result science, accurate.
Description of drawings
Fig. 1 is the utility model mounting structure scheme drawing;
Fig. 2 is the utility model embodiment one functional block diagram;
Fig. 3 is the utility model embodiment two functional block diagrams.
Among the figure, 1, car, 2, water bumper, 3, range finder module, 31, ultrasonic transmitter, 32, ultrasonic receiving device, 4, the pressure detection module.
The specific embodiment
The utility model is described in further detail with embodiment for the below.
Embodiment one:
The proving installation that a kind of elevator water bumper 2 resets, as shown in Figure 1, 2, comprise master controller, be connected with this master controller and be subjected to range finder module 3 and the pressure detection module 4 of this main controller controls and the input/output unit and the read out instrument that are connected with this master controller equally.Range finder module 3 is ultrasonic range finder, ultrasonic range finder comprises ultrasonic transmitter 31 and the ultrasonic receiving device 32 that is connected with master controller respectively and cooperatively interacts, be connected by signal generation apparatus between ultrasonic transmitter 31 and the master controller, signal generation apparatus is 555 circuit.Input/output unit is connected with master controller by wireless signal with read out instrument.Wherein, range finder module 3 is connected with master controller by wireless signal.
During measurement, open electric supply installation, proving installation is powered, car 1 descends, when the pressure detection module 4 that is arranged at water bumper 2 tops detected pressure, ultrasonic transmitter 31 began to launch ultrasonic signal, after ultrasonic receiving device 32 receives signal, master controller calculates, and gets the stroke of water bumper 2; Car 1 rises, when the pressure of pressure detection module 4 detections is zero, master controller record water bumper 2 tops at this moment are to the distance of bottom, when water bumper 2 recovers stroke fully, master controller records the time of this moment, and can record by above data needs the recovery of water bumper 2 data.
Embodiment two
Be that with the difference of embodiment one as shown in Figure 3, pressure detection module 4 is connected with master controller by wireless signal with range finder module 3.
