The utility model discloses a vertical measuring equipment carries pipe diameter in the laser rangefinder indirect measurement pipeline, and the operation personnel need not directly to measuration into the well, also need not to measuration with the help of L shaped steel pipe, under the circumstances of guaranteeing operation personnel and instrument and equipment safety, has improved measurement accuracy, has reduced intensity of labour, has the operating efficiency height, factor of safety height, characteristics that the data precision is high.
Description
Technical field
The utility model relates to a kind of pipe diameter measuring device, particularly the measurement mechanism of caliber in the underground utilities of a kind of harbour.
Background technology
Harbour underground pipeline survey is the important component part that Construction at ports is built, for the construction of port and harbor planning design and construction provides the data on basis.Interior caliber size is one of important parameter of underground utilities, and the accuracy of its data directly affects late design construction, and current general measuring method adopts steel ruler directly to measure for manually going into the well, or moves up and down indirect measurement by L-type steel pipe in-line.Wherein directly measure mode, because well head size is less, and generally there are ponding, biogas, deposit etc. in numerous downcomer line shaft bottom, and therefore directly measure difficulty comparatively large, danger is higher.Indirect measurement mode, due to the ponding, deposit etc. in pipeline shaft bottom, cannot caliber diameter in accurate measurement, therefore indirectly measure operability lower, precision is poor.
Summary of the invention
The utility model provides the measurement mechanism of caliber in the underground utilities of a kind of harbour for solving in known technology the technical matters that exists, and adopt this device, operating personnel directly measures without the need to entering well, and can obtain the higher data of measuring accuracy.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is: the measurement mechanism of caliber in the underground utilities of a kind of harbour, comprise vertical measuring equipment and perpendicular affixed level connection joint device, the laser ranging system affixed with it is provided with away from the end of vertical measuring equipment at described level connection joint device, described laser ranging system is provided with three laser instruments, the laser direction of three described laser instrument transmittings is positioned at same perpendicular, and the laser direction having two described laser instruments to launch is orthogonal; Described vertical measuring equipment is equipped with round leveling bubble and length scale chi.
Described vertical measuring equipment adopts telescopic sleeve pipe structure.
Described vertical measuring equipment adopts multistage syndeton.
The advantage that the utility model has and good effect are: adopt vertical measuring equipment to carry caliber in laser ranging system indirect inspection underground utilities, operating personnel directly measures without the need to entering well, also without the need to measuring by L-type steel pipe, when ensureing operating personnel and instrument and equipment safety, improve measuring accuracy, reduce labour intensity, there is operating efficiency high, safety coefficient is high, the feature that data precision is high, measuring accuracy meets the related request of " marine traffic engineering specifications of surveys " TJS131-2012 completely.And the utility model structure is simple, easy and simple to handle, convenient management, operating cost are low, can not cause environmental pollution.
In sum, the utility model solves current conventional equipment and method at underground utilities, inefficiency when especially having a Calibration in sewage or sedimental pipeline, dangerous high, problem that precision is poor, there is operating efficiency high, safety coefficient be high, " three high " feature that measuring accuracy is high.Can realize synchronous acquisition in measuring process, synchronously process, shortening working hours and reducing in danger coefficient, the utility model can embody great superiority.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, vertical measuring equipment, 2, level connection joint device, 3, laser ranging system, 4, pipeline.
Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, the measurement mechanism of caliber in the underground utilities of a kind of harbour, comprise vertical measuring equipment 1 and perpendicular affixed level connection joint device 2, the laser ranging system 3 affixed with it is provided with away from the end of vertical measuring equipment 1 at described level connection joint device 2, described laser ranging system 3 is provided with three laser instruments, the laser direction of three described laser instrument transmittings is positioned at same perpendicular, and the laser direction having two described laser instruments to launch is orthogonal; Described vertical measuring equipment 1 is equipped with round leveling bubble and length scale chi.
Above-mentioned vertical measuring equipment 1 can adopt telescopic sleeve pipe structure.Comprise inner sleeve and outer tube, inner sleeve is slidably connected in outer tube, is provided with pin connected construction therebetween.Also multistage syndeton can be adopted.Adjustable length, be convenient to transport and carry.
Using method of the present utility model:
During measurement, first operating personnel regulates the length of vertical measurement mechanism according to pipeline buried depth, then laser ranging system is sent in pipeline 4, the round leveling bubble regulating vertical measurement mechanism 1 to be equipped with makes it placed in the middle, then utilizes three of laser ranging system laser instruments to find range respectively and manual record ranging data.Ranging data can obtain laser ranging system through simple process and calculating and form the leg-of-mutton three limit length of sides, calculates caliber size in underground utilities according to triangle circumscribed circle method.Above-mentioned data processing method is known technology to those of ordinary skill in the art, does not repeat them here.Simultaneously, this device can utilize vertical measurement mechanism 1 and level connection joint device 2 to measure the buried depth H1 of pipeline 4, concrete grammar is: bottom level connection joint device 2 being placed in pipeline 4, the round leveling bubble in vertical measuring equipment 1 is regulated to make it placed in the middle, the height h1 that vertical measuring equipment 1 bassets is obtained by reading, can obtain the buried depth H1=H-h1 of pipeline 4, wherein, H is the height of vertical measuring equipment.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, can also make a lot of form, these all belong within protection domain of the present utility model.
