Abstract

The invention discloses a novel elevator load detector which relates to the technical field of elevator fittings. The novel elevator load detector comprises a first resistance strain gauge (1), a control circuit board (2) and a second resistance strain gauge (3), wherein the first resistance strain gauge (1) and the second resistance strain gauge (3) are both connected with the control circuit board (2); and the control circuit board (2) is connected with a connector (5) by a lead. The invention has the advantages of simple structure, lower cost and convenience in installation and maintenance, is more sensitive to the change of weight, is suitable for various elevators, and prevents damage to the elevator by overloading and potential safety hazards.

Description

A kind of later-model elevator load detector
Technical field:
The present invention relates to elevator accessory technical field, be specifically related to a kind of later-model elevator load detector.
Background technology:
As the vertical transportation hinge in the skyscraper, the vital function of elevator is self-evident, and its configuration quantity, class, load, speed and final-period management problem are determining all whether this skyscraper has the space of sustainable development.At present, elevator is faced with generally that load is low, capacity is little, slow-footed predicament in the office building, thus in the building of Yin Faing traffic freely problem also perplexing the elevator user.Especially in peak period on and off duty, elevator long problem of waiting time becomes increasingly conspicuous, and most of people are unwilling to wait for, causes the elevator overload, in the course of time, will inevitably cause accident.In order to solve the hidden danger of elevator overload, the insider is chosen in and installs the controller of weighing on the elevator additional.
The controller of weighing satisfies the elevator weighing apparatus that all elevators, Cargo Lift, medical ladder etc. are weighed and required.It generally is made up of two parts, and a part is the controller part, and a part is the LOAD CELLS part.LOAD CELLS converts weight signal to electric signal and gives the controller part through transmission cable, partly carries out calculation process by controller, finishes elevator weighing.When in the lift car during changes in weight, controller can be exported many group relaies contact signal as requested, and signal such as curtage; Controller sound and light alarm during overload is for elevator weighing and startup offer precise data.But the existing controller complex structure of weighing, cost is higher, and is not easy to installation and maintenance.
Summary of the invention:
The purpose of this invention is to provide a kind of later-model elevator load detector, it is simple in structure, and cost is lower, and is easy for installation, and is convenient to safeguard, and is responsive to changes in weight, is applicable to all kinds of elevators, has stopped damage and the potential safety hazard of overload to elevator.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises first resistance strain gage, control circuit board and second resistance strain gage, first resistance strain gage all is connected with control circuit board with second resistance strain gage, and control circuit board is connected with connector by lead.
Described first resistance strain gage, control circuit board and second resistance strain gage all are arranged at the end face of elevator rope hitch plate, and first resistance strain gage and the corresponding respectively top that is arranged at two lanyard holes of elevator rope hitch plate of second resistance strain gage.
Described first resistance strain gage and second resistance strain gage are the paper tinsel formula.
Described connector is connected with conversion/warning device on the elevator.
Principle of work of the present invention is: with top, the lanyard hole of elevator rope hitch plate as measuring point, with resistance strain gage as sensitive member, it is sticked on the measuring point of elevator rope hitch plate securely, the stressed back of elevator rope hitch plate is because measuring point generation strain, resistance strain gage also makes the resistance of strain-gauge change thereupon being out of shape, record the resistance variations size of strain-gauge again by control circuit board, and be converted to the strain value of measuring point, by bonded assembly connector on the control circuit board this strain value is transferred in the next stage unit then and handle, prescribe a time limit when measured strain value exceeds going up of this elevator, then elevator alarm device gives a warning.Because the resistance strain gage sensitivity is higher, so can in time detect the load-bearing situation of elevator.
The present invention is simple in structure, and cost is lower, and is easy for installation, and is convenient to safeguard, responsive to changes in weight, is applicable to all kinds of elevators, stopped damage and the potential safety hazard of overload to elevator.
Description of drawings:
Fig. 1 is a structural representation of the present invention,
Fig. 2 is a mounting structure scheme drawing of the present invention.
The specific embodiment:
With reference to Fig. 1-2, this specific embodiment is by the following technical solutions: it comprises first resistance strain gage 1, control circuit board 2 and second resistance strain gage 3, first resistance strain gage 1 all is connected with control circuit board 2 with second resistance strain gage 3, and control circuit board 2 is connected with connector 5 by lead.
Described first resistance strain gage 1, control circuit board 2 and second resistance strain gage 3 all are arranged at the end face of elevator rope hitch plate 4, and first resistance strain gage 1 and the corresponding respectively top that is arranged at two lanyard holes 41 of elevator rope hitch plate 4 of second resistance strain gage 3.
Described first resistance strain gage 1 and second resistance strain gage 3 are the paper tinsel formula.
Described connector 5 is connected with conversion/warning device on the elevator.
The principle of work of this specific embodiment is: with 41 tops, lanyard hole of elevator rope hitch plate 4 as measuring point, with resistance strain gage as sensitive member, it is sticked on the measuring point of elevator rope hitch plate 4 securely, elevator rope hitch plate 4 stressed backs are because measuring point generation strain, resistance strain gage also makes the resistance of strain-gauge change thereupon being out of shape, record the resistance variations size of strain-gauge again by control circuit board 2, and be converted to the strain value of measuring point, by bonded assembly connector 5 on the control circuit board 2 this strain value is transferred in the next stage unit then and handle, prescribe a time limit when measured strain value exceeds going up of this elevator, then elevator alarm device gives a warning.Because the resistance strain gage sensitivity is higher, so can in time detect the load-bearing situation of elevator.
This specific embodiment is simple in structure, and cost is lower, and is easy for installation, and is convenient to safeguard, responsive to changes in weight, is applicable to all kinds of elevators, stopped damage and the potential safety hazard of overload to elevator.
