Abstract
The utility model discloses a kind of electric class foil gauge rapid wiring device for derrick crane, this electric class foil gauge rapid wiring device utilizes the cooperation of line ball reed and lever boost motor, the lead of electric class foil gauge is set to be quickly connected in device, again by the metal bolts extraction wire being connected on device with line ball reed to strain acquirement instrument, so as to reach the purpose of quick connection foil gauge and strain acquirement instrument.Using such device can in resistor disc wiring without using electric iron, can whole cold-working, improve the efficiency when installing electric class foil gauge on derrick crane, reduce the degree of danger of staff, and can protects the safety of foil gauge, improves the reliability of circuit.
Description
Technical field
A kind of electric class foil gauge rapid wiring device for derrick crane is the utility model is related to, belongs to engineering monitoring
Technical field.
Background technology
With domestic and international Large Infrastructure Projects construction constantly update, it is perfect, the expansion of all kinds of construction projects, cause building
Industry develops rapidly and drives the development of derrick crane industry.Derrick crane is the capital equipment in architectural engineering,
It has different types of machines and good technical performance.Derrick crane is due to itself having the spies such as working space is big, cost performance is high
Point, have become one of essential large-scale construction equipment in construction site.
Tower crane safety problem is not only related to the safety and health of individual life, and to social stability and economic development
There is particularly important influence.Once generation accident, economic loss is heavy, social influence is severe.If we can monitor in real time
The ess-strain situation of tower crane structure, accurately grasps its damage status, it is possible to repairs structural damage in time, the hair to avert a calamity
It is raw.
The ess-strain monitoring to derrick crane remains in the stage using electric class electricity class foil gauge at present, and strains
The stickup of piece and quality of connection influence very big on test data result, and the pin of electric iron weld strain piece is mainly used during connection
With strain acquirement instrument cable, high-altitude hot line job is needed, operation difficulty is larger, and the feelings such as rosin joint, short circuit, foil gauge overheat easily occur
Condition, cause a large amount of wastes of time and resource.The connection of nonstandard resistance strain gage, gently can then cause loss of data, it is heavy then
The structured data collection of derrick crane is influenceed, is caused misjudgment, influences overall structure safety.
The content of the invention
Technical problems to be solved：For the technical deficiency and hardly possible of the existing electric class foil gauge of connection and strain acquirement instrument
Point, the utility model proposes a kind of electric class foil gauge rapid wiring device for derrick crane, solves prior art and deposits
The problem of.
To solve above-mentioned technical problem, the utility model uses following technology：
The line ball reed of two C fonts is installed in the insulator, after line ball reed is depressed by lever boost motor, by electricity
The lead of class foil gauge is stretched under line ball reed, and after unclamping lever boost motor, the elastic force of line ball reed compresses lead, and by electricity
The electric signal of class foil gauge is transferred on back-end metal bolt hole by two metallic conductors installed in insulator, strain acquirement
The cable of instrument then can be directly connected on the bolt of rear end, completes the quick connection of electric class foil gauge, finally passes through installation again
Device and crane structure are secured together by the fixation glue-line in device bottom surface.
The beneficial effects of the utility model are can be not required to carry other instruments with the connection electricity class foil gauge of fast and stable,
It is simple and reliable for structure.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 1, in insulator（101）In be mounted with lever boost motor（102）, line ball reed（103）, metallic conductor
（104）With metal bolts hole（105）, on circuit, line ball reed（103）, metallic conductor（104）With metal bolts hole（105）
Three connects.
The lever boost motor in the utility model（102）And it is made up of insulator, lever boost motor（102）It is upper to have one
Individual rotating shaft, can be in insulator（101）In limited rotation, lever boost motor（102）Side be cams, can during rotation
By line ball reed（103）Pressure.By pulling lever boost motor（102）Can be by line ball reed（103）Pressure, line ball reed
（103）Journey reveals Fig. 4 dispaly states, and the lead of electric class foil gauge now is stretched into line ball reed（103）In the square hole of bottom, put
Loose lever boost motor（102）, lead is automatically by line ball reed（103）Elastic compression, line ball reed（103）Journey reveals Fig. 3 and shown
Show state, Acquisition Instrument cable is then used into metal bolts（106）It is connected to metal bolts hole（105）On, connection is completed, finally
Again by being installed on the fixation glue-line of device bottom surface（107）Device and crane structure are secured together.
