Abstract

The invention discloses a leveling foot pin capable of being reversibly used. The leveling foot pin comprises a pin body (1), wherein stand bars (2) are arranged at the edge on the lower part of the pin body (1); a strut (3) with a spherical top end is arranged above the pin body (1). The leveling foot pin is characterized in that a vertically arranged rectangular groove (4) is formed in the center of the pin body (1); an opening of the rectangular groove (4) faces downward; the side wall of the rectangular groove (4) is provided with a transverse fastener (5); at least two pairs of the stand bars (2) are arranged, each pair consists of a long stand bar and a short stand bar. The leveling foot pin capable of being reversibly and forwardly used in an up-down manner, can be stably disposed no matter on a hard road or soft road, meets the measuring requirement of being easily inserted, preventing subsidence and preventing sliding, solves the problems in the prior art, and improves the leveling precision and the working efficiency.

Description

Can put upside down the measurement of the level foot pin of use

Technical field

The invention belongs to field of measuring technique, it is a kind of convenient at different pavement usages to relate in particular to, and can improve the measurement of the level foot pin of the put upside down use of measurement of the level precision and efficiency.

Background technology

Traditional leveling device is made up of a spirit-leveling instrument and two levelling staffs.When measurement, first two levelling staffs are placed in respectively to ground A, B two point (turning points, also be called transitional water on schedule), again spirit-leveling instrument is arranged on to the centre position of 2 of A, B, after utilizing leveling, the telescopical horizontal line of sight of spirit-leveling instrument is sighted respectively the absolute altitude numerical value that reads two levelling staffs, the difference of the high numerical value of institute's mark is the height differences by leveling of 2 of ground A, B, if known elevation wherein, can be extrapolated by the discrepancy in elevation elevation of another point.Levelling staff used is to be made up of rectangle chi body and the measurement of the level graduation that is labeled on chi body, and chi body bottom is that plane is surrounded by wear-resisting sheet metal.When measurement, normally first special foot pin is placed in to turning point (being also called transitional water on schedule) upper, and then levelling pole is placed on special foot pin and is measured.Existing foot pin is generally the triangle pad that the pig iron is cast, below pad, have the leg of three consistent size, above pad, having top is the pillar of sphere, under normal circumstances, leg should be inserted in soil securely, the sphere summit of pillar is as the use of erectting levelling pole and mark turning point.But existing foot pin in use can not meet easy insertion, anti-sinking, skid-resistant measurement requirement, has directly affected measuring accuracy and efficiency, concrete manifestation is as follows:

(1) when the hard surfacing such as Dang Yan highway carries out measurement of the level, leg just cannot insert hard surfacing securely, causes on the one hand foot pin to be settled unstable, and collision a little can cause the movement of foot pin; Cause on the other hand foot pin higher than road surface, can not directly road surface point be left to the leveling point of long-term use, survey crew simply abandons using foot pin for this reason, directly on hard surfacing, paints to draw a circle or cross carrys out mark leveling point, then levelling staff is directly placed on level mark.But because levelling pole body bottom is rectangular plane, be difficult to form unique, stable contact point with hard surfacing, affected precision and the efficiency of measurement of the level;

(2) in the time carrying out measurement of the level along the non-hard surfacings such as dirt road etc., due to the geologic structure difference of dirt road, cause, immobilize and the size of leg is another, therefore, leg is too thick, may just be difficult to insert in some section; And leg is too thin, there will be again sinkage in some section, affect equally precision and the efficiency of measurement of the level.

Summary of the invention

The present invention is in order to solve the existing above-mentioned technical matters of prior art, provides a kind of convenient at different pavement usages, can improve the measurement of the level foot pin of the put upside down use of measurement of the level precision and efficiency.

Technical solution of the present invention is: a kind of measurement of the level foot pin of putting upside down use, there is pad, there is leg at pad lower edge place, above pad, having top is the pillar of sphere, there is the rectangular recess of vertical setting described pad center, and the notch of rectangular recess, has horizontal securing member down on the sidewall of rectangular recess, described leg is at least two pairs, and every pair is made up of elongated leg and tubbiness leg.

Pad place between described pillar and rectangular recess bottom land is provided with pillar and regulates window, in pillar regulates window, is provided with the drive unit that can drive pillar to move up and down, and has measurement of the level division line on pillar, and pillar joins through pad and drive unit.

Described drive unit is provided with the nut that one end is fixed on the screw rod on pad and is connected with screw flight, and described pillar is placed on the other end of screw rod and joins with nut.

Described drive unit is provided with one end and is fixed on the traveller on pad, on traveller, slides and is connected to the sliding sleeve joining with pillar, is provided with tooth bar in sliding sleeve side, is engaged with tooth bar the gear being fixed on pad.

The present invention can be turned upside down and be used respectively, no matter on hard surfacing and soft road surface, all can stablize arrangement, meet easy insertion, anti-sinking, skid-resistant measurement requirement, solved the existing problem of prior art, improved precision and the work efficiency of measurement of the level.

Embodiment

Embodiment 1:

As shown in Figure 1, 2, 3: have rectangle pad 1, there is leg 2 at pad 1 lower edge place, it is the pillar 3 of sphere that pad 1 has top above, the rectangular recess 4 that there is vertical setting pad 1 center and matches with levelling staff bottom shape, the notch of rectangular recess 4 down, on the sidewall of rectangular recess 4, have horizontal securing member 5, described leg 2 is two pairs, and every pair is made up of elongated leg and tubbiness leg.Laterally securing member 5 can adopt fastening bolt, and the size of elongated leg and tubbiness leg is determined according to applied difference non-hard surfacing, requires as standard taking the easily insertion of slow foot, anti-sinking, skid-resistant measurement.

Use procedure is as follows:

In the time carrying out measurement of the level along non-hard surfacing (non-highway, dirt road etc.), similar with traditional foot pin, as shown in Figure 1,4 legs 2 of the embodiment of the present invention 1 to be inserted in soil, when soil property is relatively hard, elongated leg ensures " easily inserting "; And soil property is when relatively soft, tubbiness leg can " anti-sinking ", thereby ensures that 4 legs 2 insert in soil securely, and the pillar 3 that pad 1 top is above sphere is as the use of erectting levelling staffs 20.

When the hard surfacings such as Er Dangyan highway carry out measurement of the level, different from traditional foot pin is, as shown in Figure 2, the embodiment of the present invention is turned upside down, the bottom of levelling staff 20 is inserted in rectangular recess 4, and using horizontal securing member 5 to make it fixing, the pillar 3 that is then sphere by top is accurately erected at (generally to paint and draw a circle or cross mark) on the level mark on hard surfacing and carries out measurement of the level.When measurement, as shown in Figure 3, the height c(that requirement is measured pillar 3 is the distance of pillar 3 tops to levelling staff 20 bottoms, that is levelling staff 20 bottoms are far from the distance on ground) and corrected in measurement of the level achievement.

Embodiment 2:

As shown in Figure 4,5, 6: basic structure, with embodiment 1, with embodiment 1 difference is, pad 1 be shaped as circle or triangle, described leg 2 is three pairs, every pair is made up of elongated leg and tubbiness leg equally, laterally securing member 5 adopts tension spring.
