Abstract
The utility model discloses a kind of Portable elevator speed limiter tester, it is characterized in that this tester is a set of portable detection equipment, driving and the unit that tests the speed are achieved integrated design, and instrument is compacter.Primarily of measurement main frame, hand held controller composition.Two portion of the handle are connected by data connecting line, and hand held controller is also connected by data line with limiter of speed electric switch.In test process, measure main frame front-end driven to take turns directly and the grooving close contact of governor sheave, two data lines connect measures main frame and hand held controller, one data lines is responsible for the transmission of the speed data of the driving wheel that speed pickup collects, and another data lines is mainly used in measurement host supplying power.The uniformly accelerated motion that hand held controller internal circuit board makes measurement host driven take turns by controlling electric moter voltage.
Description
Technical field
The utility model belongs to the field of measuring technique of linear velocity, relates to a kind of Portable elevator speed limiter tester.
Background technology
Elevator, in the situations such as brake failure, wire cable rupture or damping force are not enough, may cause car speeding to fall, and security incident occurs.The effect of speed limiter system be just can when above-mentioned situation occurs stop car, thus avoid the generation of security incident, therefore speed limiter system is the indispensable important component part of elevator safety operation.Limiter of speed is in process of production through type approval test, usability can be guaranteed under normal circumstances, but after elevator comes into operation, limiter of speed may cause impaired performance even malfunctioning due to reasons such as corrosions, therefore must carry out periodic inspection to the speed limiter system of elevator." elevator surveillance inspection and periodic inspection rule " regulation, when elevator uses 2 years or occurs that limiter of speed is abnormal, should have tool elevator to check the mechanism of qualification to carry out limiter of speed inspection, to ensure that limiter of speed action is normal, ensure the safe operation of elevator.The mode of conventional inspection limiter of speed mainly adopts pastes magnet steel and hall probe conjunction measuring, the mode of independent driving is implemented, there is the shortcomings such as the comparatively large and testing process of detecting instrument heaviness, volume is loaded down with trivial details, along with the quickening of Urbanization in China, elevator quantity gets more and more, when inspection work is more and more heavier, more and more can not meet the requirement of quick inspection.
Summary of the invention
The purpose of this utility model is to provide a kind of Portable elevator speed limiter tester, adopt hand-held to drive and measure integrated design and realize the Miniaturization Design of limiter of speed tester, thus realizing that limiter of speed tester is portable to be carried and summary measures the object of elevator governor electric switch speed and mechanical action speed.Instrument adopts driver element and measuring unit miniaturized design, and mode measuring unit being integrated in driver element front end realizes the integrated design of overall instrument, substantially reduce the volume of a whole set of instrument, thus the facilitation realizing instrument is carried, due to drive with test be one lever operated, therefore reach the easy effect of measurement, thus promote the time of whole limiter of speed inspection greatly, improve checkability.
The technical scheme that the utility model adopts is, this Portable elevator speed limiter tester forms primarily of measurement main frame 1, hand held controller 2.Measure main frame (1) to be connected by data connecting line with hand held controller (2), hand held controller (2) is also connected by data line with limiter of speed electric switch.Measure main frame 1 by synchronous motor 6 and speed pickup 4 integrated, thus realize drive with measure integrated design.Hand held controller 2 is connected by data line measures main frame 1 and electric switch, electrical action signal is collected by the data line connecting electric switch, by connecting the data line gathering speed information measuring main frame 1, both cooperations detect the electric switch speed of limiter of speed.The contact measurement that described elevator governor tester adopts is realized by the grooving close contact of driving wheel (3) with governor sheave.Described measurement main frame adopts integrated design of testing the speed, and driver element is synchronous motor (6), and the unit that tests the speed is speed pickup (4).And during the generation of limiter of speed mechanical action, limiter of speed mechanical action is by stop governor sheave, thus rope sheave maximal rate and limiter of speed mechanical action speed, finally detect limiter of speed electric switch and mechanical action speed.
The beneficial effects of the utility model are relative to conventional measurement devices, it is little that this Portable elevator speed limiter tester has a whole set of instrument volume, be easy to carry, parts only have measures main frame 1 and hand held controller 2, therefore be convenient to install, drive and make in measuring process very easy with the integrated design of measuring, thus greatly promote the efficiency of limiter of speed inspection.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, this Portable elevator speed limiter tester by measuring main frame 1, hand held controller 2 forms, hand held controller 2 by data line and limiter of speed electric switch, measure main frame 1 and be connected, hand held controller by data line and limiter of speed electric switch, measure main frame and carry out data transmission.
As shown in Figure 2, measure main frame 1 to be made up of driving wheel 3, speed pickup 4, gear 5, synchronous motor 6, motor switch 7, driving wheel break-in switch 8.Synchronous motor 6 drives driving wheel 3 by gear 5, and driving wheel 3 contacts with governor sheave race, and drive governor sheave, speed pickup 4 is adjacent with driving wheel, by measuring driving wheel linear velocity thus reaching the object measuring governor sheave linear velocity.
As shown in Figure 3, hand-held control is made up of data line interface 9, display screen 10, button 11, internal circuit 12.
During measurement, after connecting according to Fig. 1, hand-held measurement main frame 1, driving wheel 3 is contacted with governor sheave cylindrical, opens motor switch 7, drive governor sheave Accelerating running, when governor rope wheel speed reaches limiter of speed electric switch speed, limiter of speed electric switch sends a signal to hand held controller 2, and hand held controller 2 collects now driving wheel cylindrical limiter of speed by data line, thus measures limiter of speed electric switch speed.When governor sheave accelerates to limiter of speed mechanical action speed, there is mechanical responsiveness in limiter of speed, thus stop governor sheave, governor sheave stop driving wheel 3, thus the maximal rate of the driving wheel 3 captured and limiter of speed mechanical action speed.Measurement result, by the transmission of data line, is finally presented on the display screen 10 of hand held controller 2.
