Abstract

The utility model relates to a simple slope measurer which is composed of a spherical rolling body, a circular arc graduated scale, a U-shaped circular arc orbit and a base seat. A substrate in a leveling rule shape and the U-shaped circular arc orbit (1) are perpendicular to and are fixed with the connecting line OO1 of the center of a circle O and the middle point of the circular arc O1, and the U-shaped circular arc orbit, the baffles on both ends of the U-shaped circular arc orbit and the base seat in a leveling rule shape can be bonded and formed by plastics. The spherical rolling body (2) can be made of glass balls. The inner circular arc of the U-shaped circular arc orbit is provided with a pair of circular arc graduated scales (3) which can be fixed on the U-shaped circular arc orbit by plastics or alloy aluminum thin plates. When the base seat of the instrument is positioned on the measured slope, the spherical rolling body in the instrument can roll automatically to the lowest point of the U-shaped circular arc orbit, and the value on the circular arc graduated scale corresponding to the top end of the spherical rolling body is the value of slope of the measured slope.

Description

Simple and easy gradient measurer

One, technical field: the utility model relates to the slope of highway surveying instrument in a kind of highway maintenance.

Two, background technology: just give highway maintenance department after a highway builds up and carry out maintenance, wherein the maintenance to the slope of highway gradient also has requirement.Slope of highway is general artificial with calculating the gradient behind line rod and the tape measuring or measuring with the slope of highway measuring instrument.And the slope of highway measuring instrument is when measuring side slope, because its rolling body is the garden cylindricality, its corner angle easily touch orbit sidewall and make its rolling not nimble, even do not put in place, just influence the accuracy of its measurement,

Three, summary of the invention: technical problem to be solved in the utility model is to design a kind of simple and easy gradient measurer, is placed on the gradient that just can demonstrate slope of highway on the slope of highway automatically.

The theoretical foundation that solve the technical problem: with reference to Fig. 3, lonely body is placed on the levelling bench when a garden, in the lonely body in garden, put into a Metal Ball (or glass bead) again, because Metal Ball (or glass bead) action of gravity, Metal Ball (or glass bead) just rest on the point of contact that the minimum point of the lonely body in garden is lonely body in garden and platform.Lonely body is placed on the inclined-plane when the garden, and the lonely in-vivo metal ball in garden (or glass bead) is under the component effect of gravity, just by O ₁Point is rolled to the new minimum point O of the lonely body in garden ₂, the lonely O in garden ₁O ₂Radian equate with its pairing garden heart angle α.Two limits according to the angle are equal with corresponding in twos vertical two angles (α, β), two limits at another angle, then the angle beta on inclined-plane and garden arc O ₁O ₂The principle that orphan's degree equates designs.

The technical scheme that solve the technical problem: this programme comprises the lonely track in U-shaped garden, the lonely shape rule in garden, spherical rolling body and pedestal.It is characterized in that having garden heart O and the lonely mid point O in garden with the garden orphan ₁Line OO ₁Vertical and with the fixed leveling ruler shape pedestal of the lonely track in U-shaped garden, have the spherical rolling body that the indication gradient is housed in the lonely track in U-shaped garden, have the lonely shape rule in the garden of on the interior garden orphan of the lonely track in U-shaped garden, being equipped with.

The beneficial effects of the utility model:, the spherical rolling body of the free rolling indication gradient is housed between the lonely shape rule of lonely track in U-shaped garden and garden because the utility model is equipped with the lonely shape rule in the garden that indicates the gradient on the interior garden orphan of the lonely track in U-shaped garden.When the pedestal of this instrument is placed on testedly when domatic, the spherical rolling body in this instrument can be automatically scrolling to the minimum point of the lonely track in U-shaped garden, and the numerical value on the lonely shape rule in pairing garden, spherical rolling body top is the value of slope of tested side slope.One man operation need not be calculated, and people from province is laborsaving, high efficiency.The accessible rolling of spherical rolling body can quick and precisely put in place.

Five, specific embodiments

With reference to Fig. 2, Fig. 3 and Fig. 4 xsect is the lonely track (1) in U-shaped garden, with U-shaped garden orphan's garden heart O and the lonely Along ent O in garden ₁Line OO ₁Perpendicular and with the leveling ruler shape substrate (4) of the lonely track concrete mutually in U-shaped garden.The lonely track in U-shaped garden, lonely track two end-stopping plates in U-shaped garden, leveling ruler shape pedestal can injection mo(u)ldings, and also available plastic bonding forms.Spherical rolling body (2) is made with Metal Ball (or glass bead).The lonely shape rule (3) in a pair of garden is housed on the interior garden orphan of the lonely track in U-shaped garden, and its available plastics or alloy aluminum thin plate are cemented on the lonely track in U-shaped garden.

The mid point O of U-shaped garden-arc orbit ₁Be defined as 0 degree value of the lonely shape rule in garden, be carved with the symmetrical gradient and the angle (scale is schematic among the figure) that increase gradually to two ends.When spending as angle among Fig. 1 30, the corresponding gradient is tg30=0.58.When the utility model is used at the construction field (site), the utility model " simple and easy gradient measurer " is placed on the side slope, the spherical rolling body of dress can be rolled to the minimum point of the lonely track in U-shaped garden along the lonely track in U-shaped garden in the instrument.The summit of spherical rolling body is exactly the gradient of tested side slope corresponding to the numerical value on the lonely rule in garden.
