Description

Stake aperture, hole disk track detector

Technical field:

The utility model relates to a kind of instrument that detects an aperture, hole and squeezed dish disk track, is aperture, a kind of hole disk track detector.

Background technology:

At present, in all kinds of building construction processes, all need to detect the stake aperture, hole of common filling pile or the aperture and the squeezed dish disk track of squeezed bored concrete pile, but existing checkout equipment mostly is electronic device, its structure is complicated, price costliness cause construction cost higher, and existing checkout equipment is subjected to, and mud disturbs bigger in the hole, can not very measure the disk track of squeezed dish accurately, therefore, existing checkout equipment can not satisfy the requirement of people's building operation.

Summary of the invention:

The purpose of this utility model is, aperture, a kind of hole disk track detector is provided, it is the instrument of pure physical construction, the simple price of structure is lower, and it is equipped with the higher gage beam of sensitivity, can measure an aperture, hole and squeezed dish disk track comparatively exactly, so satisfied the requirement of people's building operation.

The purpose of this utility model is achieved through the following technical solutions: stake aperture, hole disk track detector, it has support, power wheel and power wheel are installed on the support, rocking handle is installed on the power wheel, rocking handle is installed on the power wheel, one end of drive line is connected with power wheel, the other end is connected with guide pole, and suit sliding sleeve on the guide pole installs and measures arm on the sliding sleeve, gage beam is hinged by last rocking bar and following rocking bar and makes, last rocking bar and sliding sleeve are hinged, and following rocking bar and guide pole are hinged, mount display on the support, one end of drive line is connected with power wheel, and the other end is walked around display device and is connected with sliding sleeve.

For further realizing the purpose of this utility model realizing by the following technical solutions: axle is housed on the display device, and axle is connected with support, and index dial, pointer and power wheel are installed on the axle successively, and magnet is installed on the pointer.Last rocking bar is installed wheel with following rocking bar hinged part.Limited block is installed in the guide pole bottom.Spacing pointer is installed on the axle, and spacing pointer is contained between index dial and the pointer, and limited block is installed to the index dial bending in the needle point position of pointer on the index dial.

The utlity model has following advantage: it is simple in structure, cheap, and can measure an aperture, hole and squeezed dish disk track comparatively exactly, so solved the problem that prior art exists.

Fig. 2 is the structure for amplifying synoptic diagram of display device 21;

Fig. 3 is the A-A cut-open view of Fig. 2.

Embodiment:

Stake aperture, hole disk track detector, it has support 2, power wheel 3 and power wheel 12 are installed on the support 2, rocking handle 1 is installed on the power wheel 3, rocking handle 11 is installed on the power wheel 12, one end of drive line 14 is connected with power wheel 3, the other end is connected with guide pole 19, and suit sliding sleeve 20 on the guide pole 19 installs and measures arm on the sliding sleeve 20, gage beam is hinged by last rocking bar and following rocking bar and makes, last rocking bar and sliding sleeve 20 are hinged, and following rocking bar and guide pole 19 are hinged, and mount display 21 on the support 2, one end of drive line 13 is connected with power wheel 12, and the other end is walked around display device 21 and is connected with sliding sleeve 20.Axle 9 is housed on the display device 21, and axle 9 is connected with support 2, index dial 4, pointer 6 and power wheel 8 is installed successively, installation magnet 7 on the pointer 6 on spools 9.Last rocking bar 15 is installed wheel 16 with following rocking bar 17 hinged parts.Limited block 18 is installed in guide pole 19 bottoms.Spacing pointer 5 is installed on the axle 9, and spacing pointer 5 is between index dial 4 and pointer 6, and limited block 10 is installed to index dial 4 bendings in the needle point position of pointer 6 on the index dial 4.When the utility model is made, process each parts and assembling by above-mentioned requirements.The utility model be divided into outside the hole and the hole in the two large divisions, the lifting gear that the hole outer part is drawn together support 2, display device 21 and is made of power wheel 3, power wheel 12, rocking handle 1 and rocking handle 11; The inner detection head that constitutes by guide pole 19, sliding sleeve 20, gage beam and wheel 16 that divides in hole, gage beam more than two or two can be installed on the detection head, the identical angle of being separated by between per two gage beams, when three gage beams are installed, 120 degree of being separated by between per two gage beams.Axle 9 of the present utility model can be made into one with support 2, and power wheel 8 is the fixed pulley of irony, and index dial 4 is the disk of aluminium matter, and drive line 13 is the steel wire twisted wire, and drive line 14 is a lead line.The length of limited block 10 is greater than the distance of 4 of spacing pointer 5 and index dials, and less than the distance of 4 of pointer 6 and index dials, so limited block 10 limits the slewing area of spacing pointer 6 only.When the utility model uses, support 2 is placed on detection head places in the hole on the hole, rotation crank 1 is transferred to a position that the hole domestic demand detects with detection head, unclamping rocking handle 11 allows sliding sleeve 20 move down under the effect of gravity, gage beam under the drive of sliding sleeve 20 to around open, till running into hole wall, indicated data are the disk track of an aperture, hole or squeezed dish on this moment index dial 4, rotation crank 11 then, make shift measurement arm contraction on the sliding sleeve 20.Detection head moves down, sliding sleeve 20 drives power wheel 8 by drive line 13 and rotates, because power wheel 8 is the fixed pulley of irony, so power wheel 8 drives pointer 6 by magnet 7 and rotates, the needle point position of pointer 6 is to index dial 4 bendings, can stir spacing pointer 5 rotates, when the afterbody of spacing pointer 5 when limited block 10 on the index dial 4 contacts, spacing pointer 5 stops operating, and stop pointer 6 to be rotated further, this moment, pointer 6 just referred to null position at index dial 4, so after gage beam opened, numerical value shown on the index dial 4 was measured value.
