A kind of device for measuring arch bridge suspender length
Technical field
The utility model belongs to science of bridge building measurement apparatus technical field, it particularly relates to a kind of measurement arch bridge suspender The device of length.
Background technology
Arch bridge is with its beautiful design, the characteristics of span ability is strong, and very big proportion is occupied in the bridge construction of China.Place In bridge current check and the demand safeguarded, generally require to consider the change of arch rib line style in the checking process of arch bridge, and line style Measurement again be approx to reflect the change of arch rib line style by measuring the length change of each suspension rod on arch rib.But in arch bridge During construction and use, because suspension rod measure of the change is inaccurate and influences arch bridge line style even to have a strong impact on construction quality and lead Cause the accident of suspender replacement of common occurrence.Therefore, length of boom measurement occupies very big proportion in the health monitoring of arch bridge, a kind of The device that length of boom can be measured conveniently and rapidly just seems necessary.
Often there are two methods in conventional arch bridge suspender linear measure longimetry, one is to allow in-site measurement personnel to take loop wheel machine by line Chi is fixed at the top of suspension rod, then draws line chi from top to bottom, the length of suspension rod is determined according to the scale of measurement.Two be to pass through One be tied with weight fine rule, hang down at the top of the suspension rod, block the fine rule of top-to-bottom section, the segment length is then measured again Determine length of boom.But in actual measurement process, using method for the moment, line chi can not often ensure to be adjacent to completely suspension rod and Ensure vertical state, cause to measure length being generally higher than actual length of boom;During using method two, although can ensure that fine rule hangs down Directly, but this method needs to block fine rule repeatedly, it is relatively complicated, and drawing of the later stage measurement process due to measurement process center line in itself It is long, still there is the problem of can not ensureing precision.Limited precision that both conventional methods are measured and extensive suspension rod is not suitable for it Measurement.
The content of the invention
In order to solve the above technical problems, the utility model is long there is provided a kind of high measurement arch bridge suspender of easy to operate, precision The device of degree.
A kind of device for measuring arch bridge suspender length described in the utility model, described device includes graduation mark chi 1 and work Make cantilever 7;One end of work cantilever 7 is provided with spool 5 in lower section, up provided with workbench 11;Work the another of cantilever 7 End is in lower section provided with suspension rod folder 8;The two ends of workbench 11 are inserted in the bolt of work cantilever 7 and are erected on leveling nut 4, work Dial 3 is vertically provided with platform 11;The hole of graduation mark chi 1 through conduit 2 and workbench 11 is wrapped in spool 5 On;The one end of conduit 2 is located at the circle centre position of dial 3.
A kind of device for measuring arch bridge suspender length described in the utility model, the workbench 11 is provided with horizontal alignment Bubble 10.
A kind of device for measuring arch bridge suspender length described in the utility model, the spool 5 is solid by swing handle Determine the connection spool of nut 12 swing handle 6.
A kind of device for measuring arch bridge suspender length described in the utility model, the suspension rod folder 8 is made up of two parts, and one Part and work cantilever 7 are integrated affixed, and another part is flexibly connected with work cantilever 7.
A kind of device for measuring arch bridge suspender length described in the utility model, the suspension rod folder 8 presss from both sides elastic provided with suspension rod Nut 9.
A kind of device for measuring arch bridge suspender length described in the utility model, the leveling nut 4 has four, positioned at work Make the corner of platform 11.
The device of measurement arch bridge suspender length described in the utility model has the following advantages that:By conduit with graduation mark chi Rotate, automatically adjust angle between conduit and horizontal line, length number and angle are read by graduation mark chi and dial respectively Number, and by recording the length and angle of the part, so as to accurately measure the change of reaction length of boom;By adjusting leveling spiral shell Female and observation horizontal bubble position adjusts the level of workbench, and then ensures that measurement angle is between conduit and level Angle;In the case where not needing survey crew to climb repeatedly to suspension rod top, complete to survey by graduation mark chi and dial Amount process;In the case of less survey crew, measurement process can be quick and precisely quickly completed.
Compared with prior art, the device of measurement arch bridge suspender length described in the utility model is simple and reliable, and is easy to Implement, the large area that is particularly suitable for use in measurement suspension rod change, and measurement accuracy is of a relatively high;Arch bridge suspender inspection can be effectively improved The efficiency of survey, while also mitigating the workload and work difficulty of testing staff, significantly increases operating efficiency, has well Economic benefit and social benefit.
