Description
Technical field
The utility model relates to the support disk pile field, especially a kind of extruding-enlarging branch tray castinplace pile shaping checkout equipment.
Background technology
The characteristics of propping up the dish castinplace pile are to have increased on the basis of common cast-in-place concrete pile together or the multiple tracks extruding-enlarging branch tray, this increases a dish is the outstanding feature that a dish castinplace pile is different from existing pile foundation, a dish that increases makes the change of the force mechanism generation essence of whole pile foundation, thereby the quality that dish is propped up in squeezed shaping is most important.In formation of pile, the detection content of support disk pile pile quality except that the detection of common filling pile, also had the test item of a disk track of dish, dish position.
Existing support disk pile detects and comprises that hole depth detection, aperture and disk track detect.Aperture and disk track detect can be classified as 3 classes: 1, bit diameter behind the detection pore-forming; 2, adopt caliper to inspect by random samples; 3 usefulness sound wave hole wall analyzers detect.
Adopt caliper to form by four hole diameter arms that are mutually 90 degree by mechanical gauge head, measure begin before, four hole diameter arms close up and lock with spring; Four test arms are opened downwards during work, the test arm end is close to a hole wall, along with upwards promoting of caliper, the hole diameter arm opens or indentation drives following moving on the motion bar in the sealing drum along the rough shape face of hole wall is corresponding, the resistance contact point of four groups of series connection is slidably reciprocated, constantly change resistance sizes,, can draw the size and the shape of aperture, hole wall by the variation of record loop voltage signal.The inspection of dish distance detects according to construction note and in-site measurement.Become the detection of hole perpendicularity to adopt sound wave hole wall detector.
Detect main electric impulse signal with sound wave hole wall analyzer, behind amplifier, be converted to sound wave and emission by transmitting probe by oscillator generation certain frequency.Sound wave emissions can be reflected after running into the interface of different medium.The sound wave that receiving transducer will receive after the reflection converts the signal of telecommunication to, through handling the hole wall aperture that can draw measurement.
When slide wire resistance caliper harmony wave hole wall analyzer detects, all need the extruding-enlarging branch tray host header to be lifted by crane and be lifted out a hole, again tester is put into from the aperture, need the another one operation, rather than when a dish is squeezed, just finish in the lump; Caliper when work is the hole diameter arm and 2 points that contact in a hole to survey zone, and the working region is little, and operating efficiency is not high; In addition, after the pile hole extruding-extending, stake exists mud and water within the hole, and condition of work is more abominable, to the opening and draw in all and affect of four well arms of slide wire resistance caliper, the water-tight under the slip operating mode of caliper raising rod has been made strict requirement.
The shortcoming of existing measuring apparatus: 1) need extra erecting equipment, need equipment especially that measureing equipment is put into institute peg hole during work; 2) measure the real-time deficiency, operating efficiency is not high, can not go out the aperture hole depth at a squeezed transient measurement of dish; 3) be subject to the working environment influence, the waterproof sealing performance is proposed very high request.
Summary of the invention
For the pile foundation that overcomes existing support disk pile props up that operation inconvenience, the real-time of dish aperture hole depth checkout equipment is not high, inefficiency, incompatible abominable condition of work, the utility model provides a kind of easy and simple to handle, real-time, high efficiency, effectively adapts to the extruding-enlarging branch tray castinplace pile shaping checkout equipment of abominable condition of work.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of extruding-enlarging branch tray castinplace pile shaping checkout equipment, comprise working platform, rotary hydraulic motor, extension bar, squeezed mechanism of prop shaping machine and hydraulic control center, described rotary hydraulic motor is installed on the base, described base is installed on the described working platform, described rotary hydraulic motor and described extension bar are in transmission connection, described the squeezed mechanism of dish shaping comprises hydraulic cylinder, piston rod and four connecting rods prop up the squeezed arm of dish, described hydraulic cylinder is installed in the lower end of described extension bar, hydraulic piston is installed at described hydraulic cylinder inner chamber middle part, described piston rod is fixedlyed connected with described hydraulic piston, described piston rod stretches out the lower end of described hydraulic cylinder, described piston rod props up the squeezed arm of dish with described four connecting rods and is connected, described rotary hydraulic motor all is connected with described hydraulic control center with hydraulic cylinder, in described hydraulic cylinder, install in order to detect the displacement transducer of piston rod shift motion, one end of described displacement transducer is installed in the roof of the upper cavity of hydraulic cylinder, the other end of described displacement transducer is installed in the upper end of described hydraulic piston, described displacement transducer be connected in order to calculate the dish hole size detection control module that detects that realizes being shaped according to the piston rod displacement.
