Description

A kind of Lei Shi presss from both sides analyzer

Technical field

The utility model is related to detecting instrument, more particularly to a kind of Lei Shi folders analyzer.

Background technology

Lei Shi folder analyzers are a kind of detecting instruments for being used to examine Lei Shi to press from both sides aeroelastic requirements, are determined the water of normal consistency The swell value that cement paste is filled up after boiling certain time through maintenance and boiling in Lei Shi clamp ring moulds.

Lei Shi presss from both sides analyzer before test, it is necessary to detect the left arm frame of Lei Shi folder analyzers and the connection jail of cradling piece Soundness, and staff can forget test when pressing from both sides analyzer using Lei Shi, light is by estimating the company to left arm frame and cradling piece The degree of connecing is judged, once the left arm frame of Lei Shi folder analyzers and the fastener of cradling piece loosen, can cause Lei Shi folder measure The left arm frame of instrument and cradling piece are no longer orthogonal, the Lei Shi testing results for pressing from both sides analyzer are impacted, the sky also improved Between.

Utility model content

The purpose of this utility model is to provide a kind of Lei Shi folders analyzer, when left arm frame and insecure cradling piece fixation, Alarm will be sent, for pointing out staff.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of Lei Shi presss from both sides analyzer, including cradling piece, left arm frame, and the cradling piece is supplied to few two with being equipped with left arm frame The screwed hole that piece bolt is worn and screw thread coordinates, in addition to baffle plate, the support is provided with to be installed and mutual with screwed hole for baffle plate The mounting groove being connected, side of the mounting groove away from left arm frame, which is provided with to contradict with baffle plate, is connected to detection bolt and support Set in the pressure physical quantity of bar and the pressure-detecting device that pressure physical quantity is converted to pressure detecting signal, the mounting groove There is the fixing groove that voltage supply force checking device is fixed and interconnected with mounting groove, in addition to be coupled to pressure-detecting device to receive Pressure detecting signal and output pressure compare the pressure comparison means, corresponding with minimum pressure physical quantity for providing of signal Pressure reference line signal to pressure comparison means standard apparatus, be coupled to pressure comparison means to receive pressure comparison signal simultaneously The pressure control device of output pressure control signal, be coupled to pressure control device with receive pressure controling signal and corresponding to pressure Force control signal is to realize the alarm device of alarm；

When the pressure detecting signal that the pressure comparison means is received is less than benchmark value signal, the pressure control device Alarm device is controlled to realize alarm.

Using such scheme, by the setting of pressure-detecting device, the elasticity to bolt is detected, only works as pressure Detection means detect two pieces of bolts to the pressure that is subject to of baffle plate be more than the reference signal of standard apparatus when, alarm device will not Alarm, otherwise will send alarm, fill in staff, pressure-detecting device is arranged on baffle plate to by bolt to baffle plate Pressure is detected that, when there is one piece of bolt fixation to release, pressure-detecting device is detected only by one piece of bolt by pressure-detecting device Fixed strength is reduced, and causes baffle plate to protrude, and is reduced the pressure that pressure-detecting device is detected, warning device is alarmed, real It is strong with property.
