Technical field
The utility model relates to pavement detection equipment technical fields, and in particular to a kind of intelligence pavement benkelman beams deflectometer.
Background technique
Flexure is one of the important technology index of Road Design and highway engineering quality status evaluation, it reflects on the whole The integral strength of each level in road surface, the intensity of roadbed are generally reflected with the modulus of resilience.If deflection value is excessive, deformation Bigger, each layer in road surface is also easy for rupturing.Deflection value is excessive, material properties of the reason generally with each layer in road surface, and thickness is whole Body is related.
Deflection value refers under the effect of defined standard axle load, total vertical change that roadbed or road surface wheel gap position generate Shape (total flexure) rebounds vertically deformation values (rebound deflection), as unit of 0.01 mm.Usually said rebound deflection value is The quasi- rear axle of index carries the maximum rebound deflection value at two-wheel group wheel gap center.General pavement benkelman beams deflectometer is also backman beam.It adopts Made of lever principle, road surface can be deformed under the action of car load, and vehicle restores to the original state after leaving, measurement standard When the automobile of axis weight passes through road, the vertical deformation or rebounds upon deformation value that wheel position generates can show the rigid of road surface Degree and bearing capacity.Deformation measured directly is known as total flexure, and deformed springback capacity is rebound deflection.
Current Beckman beam type benkelman beams deflectometer generally using mechanical dial gauge, needs a dial gauge in use Bracket, and lever tail also needs to install a high bar after benkelman beams deflectometer, dial gauge measuring rod is pressed against on high bar and is measured, Dial indicator bracket will be reapposed when causing to measure every time, and the high bar of lever tail after benkelman beams deflectometer is installed, is virtually increased The volume of benkelman beams deflectometer, it is all one section of public affairs by manually being read, being recorded in measurement process that it is more inconvenient, which to use and carry, Road will measure multiple points, heavy workload, and artificial reading easily mistake occurs, has an impact to the accuracy of entire measurement result.
Urgently proposing that one kind does not need indicator bracket, volume is smaller, and using more convenient, it is able to achieve and automatically records reading, and The intelligent benkelman beams deflectometer uploaded by electronic information equipment.
Utility model content
The utility model provides a kind of intelligent pavement benkelman beams deflectometer.Lever tail after dial indicator bracket and benkelman beams deflectometer is not needed High bar, the volume of benkelman beams deflectometer is smaller, carry and use it is more convenient, and pass through electronic centigrade scale, wireless data transmitter, electricity Source, the realization of infrared temperature detector automatically record reading, and the intelligent pavement benkelman beams deflectometer of data is transmitted by wireless signal.
The specific technical solution of the utility model is:
A kind of intelligence pavement benkelman beams deflectometer, including preceding lever interconnected and rear lever, the pedestal of support connect pedestal It further include measurement sleeve, electronic centigrade scale, measurement mandril, cushion, fastener, Wireless data transmission with the shaft of rear lever Device, measurement sleeve setting lever after described are installed far from the shaft tail end, the electronic centigrade scale by fastener At the top of the measurement sleeve, the measuring rod of electronic centigrade scale is passed through in measurement sleeve roof insertion measurement sleeve, the fourth type Measurement mandril the measurement sleeve inner is set, the measurement sleeve inner bottom is provided with cushion, the no line number It is arranged the bottom of on according to conveyer, is connect by data line with electronic centigrade scale.
It is further preferred that further including infrared temperature detector, the infrared temperature detector is arranged in pedestal On, it is connect by data line with wireless data transmitter.
It is further preferred that further including that measurement extends mandril, the measurement, which extends mandril, to be connected with the measurement mandril It taps into and adjusts measurement range.
The beneficial effects of the utility model are: by installing measurement sleeve, electronic centigrade scale, measurement top in benkelman beams deflectometer tail portion Bar is to no longer need the high bar of lever tail after dial indicator bracket and benkelman beams deflectometer, the volume of benkelman beams deflectometer is smaller, carries and uses It is more convenient, and reading is automatically recorded by electronic centigrade scale, wireless data transmitter, power supply, the realization of infrared temperature detector, The intelligent pavement benkelman beams deflectometer that data are transmitted by wireless signal, greatly reduces the workload of survey crew, reduces because of people Part work and part study number, misregistration bring measurement error, measurement data can directly be transferred into computer, by specialty analysis software into Row processing, scene just have as a result, shorten the time that entire measurement process needs, improve work efficiency, and device structure is simple, Convenient for utilization and extention.
