Abstract
The utility model discloses a ground flatness tester, comprising a rectangular horizontal support, wherein each of the four corners of the rectangular horizontal support is equipped with a height adjusting leading screw rod to enable two side rails in the length direction to keep horizontal, and a laser range finder is fixed on a transverse rod slidable along the two slide rails, and can be pulled to slide along the horizontal support by an external force through a drawn line, thus determining the distance between the slided ground and the laser range finder, and further calculating the ground flatness. The ground flatness tester can replace a traditional hand-operated ruler measuring, and improve the measuring precision and working efficiency of the ground flatness.
Description
Technical field
The utility model belongs to building ground testing flatness field, and the flatness that relates to ultra plane earth or ultra plane earth detects, and is specifically related to a kind of ground flat degree proving installation that utilizes laser distance measuring principle to design.
Background technology
Ultra plane earth is the ground construction technology of at present in the world high standard and highest standard; It designs for flatness, fastness to rubbing and the prolongation ground of improving ground serviceable life; Generally be used for High Level Rack logistic storage ground, can guarantee the normal use of high-order fork truck.Because ground possesses the flatness and the levelness of extra accuracy, fork truck train stability, non-migration can reduce the maintenance rate of fork truck, can guarantee long-term normal use the on ground simultaneously, increase work efficiency.
This type ground must possess higher flatness, could guarantee normal, the safe handling of high-order fork truck.Ground flat degree generally will meet standard ACI 117 or the Britain concrete specification BCSTR34 of the ACI 302.1R of ACI; The general flatness that adopts the F-number value to represent ground, flatness F-number is that the continuous changing value of every 300mm spacing drop is represented the rugged and rough of ground when measuring along the slotted line in tested zone.
At present, generally adopt 3 meters guiding rulers to carry out the measurement of ground flat degree, and the influence of this measuring method human factor is bigger, precision is not high, and efficient is very low.
The utility model content
The purpose of the utility model is to provide a kind of ground flat degree proving installation to measure to replace the traditional hand guiding ruler, improves the measuring accuracy and the work efficiency of ground flat degree.
The utility model technical matters to be solved realizes through following technical scheme:
A kind of ground flat degree proving installation comprises a horizontal stand and is located at the laser range finder on this horizontal stand that laser range finder is slippage in the horizontal direction.
Said horizontal stand is a rectangle, and four jiaos of horizontal stand are separately installed with and highly regulate leading screw.
Said laser range finder is fixed on the whippletree, and a pulley is respectively installed at the whippletree two ends, and pulley is placed on the two long limits of horizontal stand.
3.5 meters of said horizontal stand length, 40 centimetres of width.
But said laser range finder connects the draught line that a horizontal direction applies tractive force.
Said laser range finder signal connects a computing machine.
The utility model makes that through regulating leading screw two orbits remain on horizontal level on the horizontal stand length direction; Through the tractive force effect laser range finder can be slided along two horizontal rail; Thereby can measure the distance of the ground distance distance measuring equipment that is slipped over; The difference of height of upper ground surface along its length that draws, and then calculate the flatness on ground.The utility model ground flat degree proving installation can replace the traditional hand guiding ruler to measure, and improves the measuring accuracy and the work efficiency of ground flat degree.

Embodiment
The utility model provides a kind of ground flat degree proving installation, its structure constitute and principle of work referring to shown in Figure 1: rectangle horizontal stand 3 of the utility model design, length about 3.5 meters, 40 centimetres of width; Four jiaos of horizontal stand 3 are separately installed with and highly regulate leading screw 2, make that through regulating leading screw 2 two limits (slide rail) remain on horizontal level on the length direction; The core of the utility model measurement mechanism is a cover laser range finder 5; Laser range finder 5 is fixed on the whippletree 7, and a pulley 4 is respectively installed at whippletree 7 two ends, and pulley 4 is placed on the two long limits of horizontal stand 3; Laser range finder 5 also connects a draught line 6; External force slides laser range finder 5 through draught line 6 pulling laser range finders 5 along two horizontal rail (two long limits of horizontal stand) under the tractive force effect, thereby can measure the distance of the ground 1 that slipped over and laser range finder 5; Computing machine through being connected with laser range finder 5 signals draws along the difference of height of 3 meters direction upper ground surfaces of length, and then calculates the flatness on ground.
In the utility model, laser range finder 5 and sub computers thereof can be business-like product, carry PT80 series laser range sensor etc. like the card Sa; Horizontal stand 3 can be formed by the stainless steel processing and fabricating, but must guarantee that support has very high rigidity; Horizontal stand 3 also can be formed by the aluminium section bar processing and fabricating, but must guarantee that support has very high rigidity; Draught line 6 can be spurred by manual work, also can be drawn automatically by electric device.
The utility model course of work:
At first horizontal stand 3 is placed on the tested ground 1, make laser range finder 5 be arranged on the measurement track on tested ground 1 (like Fig. 1 dotted line for measuring track), and the slide rail of horizontal stand 3 both sides is parallel with the measurement track on tested ground 1.Then, regulate the height in 3 four bights of horizontal stand and regulate leading screw 2, make the slide rail of horizontal stand 3 both sides keep horizontal level, the check of horizontality can adopt aid such as surveyor's staff to check.After horizontal stand 3 is adjusted to level; Open the switch of laser range finder 5; Begin to measure; And the pulling draught line 6 let laser range finder 5 on the measurement track on tested ground 1, slide, sub computers reaches the time that ground turns back to laser range finder 5 receiving traps again according to laser, multiply by the aerial speed of laser again; Record the distance of every bit ground identity distance laser range finder 5 laser emission point on this measurement track, and then calculate the ground flat degree F-number value of this tested ground survey track.
