Abstract

The utility model relates to a highway slope surveying instrument, relating to the survey of the slope and the angle of the highway. The highway slope surveying instrument is composed of a straight rule (1) and a graduated disk (9). The graduated disk (9) is provided with pairwise orthogonal four indicated needles via a shaft (5); the end of one of the four indicated needles is provided with a heavy bob; the graduated disk is marked with a high wall slope (4), the slope of the transverse slope of the road bed (6), and the angle (7); the reading can be directly made while in use. The utility model has the advantages of convenience for carrying, light weight, convenient operation, high speed. The end of the straight rule is provided with a handle (8). The carrying can be completed by one person.

Description

Highway slope surveying instrument

A kind of highway gradient measurer relates to the highway gradient, goniometry.

At present, highway division all adopts ruler (having scale and air level) and steel tape to measure the gradient.This kind method needs 2 people to finish at least, and more loaded down with trivial details.Chinese patent CN85200657 discloses a kind of gradient measurer in addition, be by two long stents such as grade, half garden shape index dial is housed on support, line is housed in the point of crossing of support to be weighed down, comprise that also a line weighs down regulating device and vernier caliper, this apparatus structure is looser, uses inconvenience, and is unfavorable for carrying.

The utility model purpose is according to measuring the problem that exists in the gradient at present, a kind of novel gradient measurer being provided.

The utility model is by ruler (having air level and scale), constitute with an index dial, with bolt index dial is fixed on the ruler, certainly also available other mechanical method fixation is equipped with mutually perpendicular in twos four pointers by axle in the index dial, is carved with grade of side slope, angle, the roadbed horizontal wall inscription gradient on the index dial, when the ruler level (air level is placed in the middle), pointer (13) (15) points to " 0 ", and pointer (10) points to " ∞ ", and pointer (12) points to " 90 ".The termination of four one of them pointers of pointer has heavily vertical, and heavily the meaning of Chuiing is meant in the termination of pointer certain weight, can make this pointed always vertically point to surface level.On corresponding index dial cloche, magnifier is housed with transverse slope.For the ease of the end that is carried at ruler handle is housed.

Accompanying drawing 1 is the utility model front elevation;

Accompanying drawing 2 is accompanying drawing 1 partial top view;

Accompanying drawing 3 is accompanying drawing 1 side view;

Below 1,2,3 pair of the utility model describes in detail with reference to the accompanying drawings:

The utility model is made of ruler (1) and index dial (9), ruler adopts H-shaped material, thickness 2MM, length 85CM, air level (2) and scale band (6) are housed on the ruler, index dial is the garden dish, housing adopts aluminium frame (17), with bolt (3) index dial (9) is fixed on the ruler (1), by axle (5) mutually perpendicular in twos four pointers (13) (15) (12) (10) are housed in the index dial (9), wherein heavily hang down (11) are equipped with in the termination of pointer (12), be carved with grade of side slope (4) on the index dial (9), angle (7), the roadbed horizontal wall inscription gradient (6), grade of side slope portrayal 1:0-1:3, horizontal wall inscription gradient portrayal 0%-16%, 0 °-90 ° of angle portrayals.When ruler (1) level (in the air level genus), pointer (13) (15) points to " 0 ", and pointer (10) points to (∞), and pointer (12) points to 90 °.With the corresponding index dial cloche of the horizontal wall inscription gradient (6) on 8 times of magnifieres (14) are housed.For ease of carrying, handle (8) is housed in the termination of ruler (1).

The utility model there is no strict restriction to length, the shape of ruler, but length is preferably between the 70-90cm, and index dial can be in the optional position of ruler, and the rotating shaft in the index dial only need be satisfied pointer and freely rotates, and can select multiple rotational structure for use.

The utility model can rapid test the roadbed side slope gradient, the grade of side slope of pier, curb transverse slope, shoulder width, have the characteristics of a multi-purpose instrument, in light weight, carry, easy to operate, measuring speed is fast, only needs a people to finish.

Claims

1, a kind of highway gradient measurer, feature is to be made of a ruler (having air level and scale) and an index dial, with bolt index dial is fixed on the ruler, by axle mutually perpendicular in twos four pointers are housed in the index dial, be carved with grade of side slope, angle, the roadbed horizontal wall inscription gradient on the index dial, when the ruler level (air level is placed in the middle), pointer (13) (15) points to " 0 ", pointer (10) points to " ∞ ", and pointer (12) points to " 90 ".

2, highway gradient measurer according to claim 1 is characterized in that the termination of four one of them pointers of pointer has heavily vertical.

3, highway gradient measurer according to claim 1 is characterized in that on the corresponding index dial cloche with the transverse slope position magnifier being housed.
