Abstract
The utility model relates to an aperture detecting device, which is composed of an upper bracket and a detecting frame which are connected by wire ropes. The upper bracket is formed by the connection of two ladders through axle pins. In the detecting frame, a detecting rod is connected with a lower connecting block which is connected with a lower detecting arm by axle pins; the lower detecting arm is connected with an upper detecting arm by axle pins; the upper detecting arm is connected with an upper connecting weight by axle pins; the weight is movably connected with the detecting rod; the intermediate axle pin of each set is connected with a wheel. The device is used for detecting the aperture size of squeeze expanded bored concrete piles for aperture drilling of buildings. The utility model is not influenced by the specific gravity of mud, can accurately measure the aperture size of various cross sections of expanded aperture bodies, and can measure the aperture size at any time like a ruler which is used for measuring objects, so the aperture detecting device has the advantages of direct viewing, reliability, low cost, simple operation, practicability and convenience. Because the wheels make contact with aperture walls, the aperture walls can not be scratched, so that the integrity of the aperture walls can be ensured. The utility model provides an effective method to detect the quality of bored concrete piles for shaped aperture drilling.
Description
Technical field:
The utility model relates to a kind of pick-up unit in building engineering field, relate in particular to a kind of in building operation the hole diameter detection apparatus of the squeezed bored concrete pile of special-shaped boring.
Background technology:
Because the high speed development and the widespread use of multi-nodal enlarging bored concrete pile, to the detection of this non-uniform pile pore-forming, especially process detects just becomes very important part.Under current prerequisite of grabbing construction quality greatly, if detect with well-calipering apparatus, the one, the expense height, two is not directly perceived, and the test rod that detects of well-calipering apparatus stretches the end less than the hole enlargement body, can not well react the diameter of hole enlargement body.If detect with the ultrasound wave apertometer, because underwater operation is holed with mud off, so the mud balance in the hole is bigger, and the proportion of mud is following big top little in the hole, the hole wall reflected signal does not cause detection unclear by force, and expense is higher, like this with regard to the development of this multi-nodal enlarging bored concrete pile of serious obstruction and shaped pile.
The utility model content:
The purpose of this utility model is: design a kind of device that detects the pore size of the squeezed bored concrete pile of boring, make it not influenced by the mud balance size, and the diameter that can accurately measure the hole enlargement body comprises the pore size of non-uniform pile, and simple to operate, reliable, easy to use.
The utility model is achieved in that by testing stand, wire rope and upper bracket to be formed, and wherein connects upper bracket above the wire rope, below the joint detection frame.Upper bracket is to be formed by the pivot pin link by two single face ladders, and a steel wire rotating disk is arranged on each ladder, on each rotating disk handle is arranged, and rotating shaft and wire rope stud with the scale sign by certain size on the wire rope.Testing stand comprises test rod and the lower connecting block that is connected, lower connecting block is connected with following detection arm by pivot pin, following detection arm is connected with last detection arm by pivot pin again, last detection arm again by pivot pin with on be connected pouring weight and connect, on connect pouring weight and flexibly connect along test rod.Every group of middle pivot pin of testing stand connects a wheel (pivot pins connect a wheel in the middle of promptly having three or four).
Good effect of the present utility model is: this device is not subjected to that mud balance influences in the hole, can accurately detect, because in the process that detects, testing stand is put into slowly at the bottom of the hole earlier, draw on then test rod being blown slowly, last connection pouring weight moves up and down at gravity situation lower edge test rod, and the size that moves can reflect the size that detection arm is laterally gone out, and detecting device can change with the variation in aperture.Because of adopting the profiling type polytypic to detect, so measure the size of hole enlargement body diameter very accurately, because be wheel contact hole wall, Gu do not produce scuffing, guaranteed the integrality of hole wall, this is to detect special-shaped cast-in-situ bored pile quite good detecting device, because of basic identical on its structure with the structure of extruding-extending machine, and be to survey its maximum gauge part with well-calipering apparatus, can't extend into the largest portion of hole enlargement body because of the well-calipering apparatus structure, so can't reflect the accurate size of hole enlargement body, and this device is to adopt polytypic can survey the size in all size aperture at any time.Ultrasound wave aperture detector is because the mud balance in the hole of squeezed boring when big in addition, can't finely measure the boundary of hole wall and mud, therefore can't measure the size in hole, if cause the hole of collapsing and the mud dilution just can't be carried out retaining wall to the hole, the expense in a hole of the every detection of ultrasound wave aperture detector is very high, because extruded and extended pile is to save cost, many detection costs have been increased yet detect, extruded and extended pile just can not get good application like this, and this device is not subjected to mud influence, can survey at any time, and is intuitive and reliable as measuring thing with a yardstick, its expense is extremely low, for the quality testing of special-shaped cast-in-situ bored pile provides effective means.

Embodiment:
Shown in Fig. 1-2: a steel wire rotating disk 13,14 is arranged respectively on each single face ladder of upper bracket, and handle 15,16 and wire rope 9,10 and rotating shaft are arranged on each rotating disk.Upper bracket 12 is opened, supported on the ground.With steel wire rotating disk 13 rotate connect pouring weight 7 testing stand put into the hole by going up on the wire rope 10 joint detection framves at the bottom of, and then the test rod 8 that steel wire rotating disk 14 is rotated by wire rope 9 joint detection framves draws on slowly, testing stand is opened three groups or four groups of detection arm 3 and 5 by pivot pin 2,4,6 with lower connecting block 1 under the action of gravity of last connection pouring weight 7 and is supported on the hole wall 17, all connect a wheel on each pivot pin 4, be that wheel that the middle pivot pin on the testing stand connects has 3 or 4 (in Fig. 1-2, being the explanation duty two groups of detection arm of only having drawn).In last process of drawing testing stand, along with the change-detection frame in aperture also opens along with the variation in aperture or reclaims, last contiguous block 7 in the testing stand moves up and down along test rod 8, upper and lower displacement by last connection pouring weight 7 also moves up and down when driving wire rope, because of wire rope 9 is initiatively to restrict, by the scale on the wire rope 9 11 can be clear and definite the degree of depth of telling your detected hole enlargement body, and by the displacement difference of the scale on wire rope 9 and the wire rope 10 between them can be clear and definite the diameter of telling your hole enlargement body, because of the squeezed arm of extruding-extending machine moulding and the size dimension of the detection arm of pick-up unit are identical so this detection method also can be described as profiling type detects, this detection is simple, reliable a kind of convenient accurate test method of formula.
Shown in Fig. 3,4: the vertical view of testing stand, testing stand can be that branch detection arm structures such as three groups are formed, and also can be that four groups of symmetry detection arm structures are formed.
