Technical Field

The invention relates to the field of drawing equipment, in particular to a surveying and mapping device convenient for drawing.

Background

Surveying and mapping refers to measuring, collecting and drawing the shape, size, spatial position and attributes of natural geographic elements or surface artificial facilities. At present, the open-air survey and drawing in-process, there is not the bearing structure who is used for supporting drawing platform basically, consequently, during open-air survey and drawing, the surveyor can carry the support usually to support drawing platform, the convenience is drawn at survey and drawing in-process. However, since the problem of uneven ground is very likely to occur in the field, the problem of tilting of the drawing platform is likely to occur when the drawing platform is supported by the stand, which is inconvenient for drawing, and the drawing platform may fall down due to excessive tilting. And, when the support supported drawing platform, if lack the mounting between drawing platform and the support, then drawing platform still dropped from the support easily, if there is the mounting, then need the surveyor to install after the support, recycle the mounting and fix drawing platform on the support, it is comparatively troublesome to operate.

The specific implementation process is as follows: in the surveying and mapping process, the surveyor lays the drawing platform subaerial, specifically, lifts up the drawing platform, and bracing piece 17 breaks away from the standing groove 301 of 3 bottom surfaces of bottom plates automatically under the action of gravity, and the bottom of bracing piece 17 offsets with ground, and certain position of the upper segment of bracing piece 17 offsets with the bottom of limiting plate 18, and bracing piece 17 slopes, and the incline direction of bracing piece 17 outwards to the realization is to the support of drawing platform, convenient operation, simple.

When ground is not flat, the bottom of a certain supporting rod 17 can not contact with the ground, and at the moment, a surveyor can make the bottom of the supporting rod 17 contact with the ground by adjusting the length of the supporting rod 17, so that the drawing platform is stably supported. The process of adjusting the length of the support bar 17 is as follows: the inner rod 172 is fixed, and the outer rod 171 is rotated counterclockwise, so that the outer rod 171 moves axially relative to the inner rod 172, and thus the length of the support rod 17 is increased until the bottom end of the support rod 17 (i.e., the bottom end of the outer rod 171) contacts the ground.

Then, the surveyor lays paper on the upper surface of the sliding plate 1, and in the process of laying the paper, the surveyor lifts up the pressing plate 6 so that the paper passes through the space left between the pressing plate 6 and the sliding plate 1. Subsequently, the surveyor closes switch 12 on the pressing plate 6 on the right side, so that electromagnet 9 in the pressing plate 6 on the right side is electrified, the pressing plate 6 on the right side presses the paper on sliding plate 1, then, the surveyor pushes the pressing plate 6 on the left side to move leftwards, and in the process, the pressing plate 6 flattens the paper to avoid the paper to have wrinkles. After the left-hand press plate 6 is moved to the left end of the slide 1, the surveyor closes the switch 12 on the left-hand press plate 6, so that the left-hand press plate 6 presses the left end of the paper against the slide 1. Then, the surveyor disconnection is located the switch 12 on the clamp plate 6 on right side, promotes clamp plate 6 that is located the right side again and moves right, flattens the paper, and behind the clamp plate 6 that is located the right side shift sliding plate 1's the right-hand member, the surveyor closes switch 12 on the clamp plate 6 that is located the right side once more for clamp plate 6 that is located the right side compresses tightly the right-hand member of paper on sliding plate 1, thereby realizes the fixed to the paper, makes things convenient for the surveyor to draw.

After the paper is fixed, if the orientation or the horizontal position or the inclination angle of the paper needs to be adjusted, the adjustment can be carried out according to the following operations: when the orientation of the paper is adjusted, the rotating plate 2 is rotated, after the orientation of the paper is adjusted, the fixing of the rotating plate 2 is realized by the fixing component III, specifically, the tight abutting screw 16 is rotated, so that the left end of the tight abutting screw 16 abuts against the second rubber layer 5 on the peripheral wall of the rotating plate 2, and the rotating plate 2 is prevented from rotating.

When adjusting the horizontal position of paper, rotate adjusting screw 14 can, specifically, clockwise rotation adjusting screw 14 drives slide 1 and slides left, anticlockwise rotation adjusting screw 14 drives slide 1 and slides right to the horizontal position of adjustment paper, and then makes the surveyor's drawing in-process all the time be to the central part application of force of commentaries on classics board 2, so that bracing piece 17 supports drawing platform more steadily, avoids drawing platform to empty.

When the inclination of adjustment paper, surveyor's accessible adjusts the length of bracing piece 17 for the length that lies in two bracing pieces 17 with one side is good at or is short in the length that lies in two bracing pieces 17 of opposite side, thereby makes the whole slope of drawing platform, and then makes the paper slope, satisfies surveyor's drawing custom or drawing requirement.

After the drawing is finished, a surveyor only needs to disconnect the switch 12 on the pressing plate 6, so that the electromagnet 9 loses magnetism when power is off, and the paper can be taken down from the sliding plate 1.

Example two

The difference between the present embodiment and the first embodiment is: the T-shaped sliding chute 101 on the sliding plate 1 extends to the bottom surface of the sliding plate 1, and the longitudinal sections of the left side and the right side of the bottom plate 3 are circular arc-shaped. In this embodiment, since the T-shaped sliding slot 101 extends to the bottom surface of the sliding plate 1, the T-shaped sliding part 7 in the first fixing assembly can slide to the bottom surface of the sliding plate 1, that is, the pressing plate 6 can move to the bottom surface of the sliding plate 1, and therefore the first fixing assembly can press the two ends of the paper to the bottom surface of the sliding plate 1, and the first fixing assembly is prevented from being located on the upper surface of the sliding plate 1 to affect the drawing of the surveyor.

The foregoing is merely an example of the present invention and common general knowledge in the art of designing and/or characterizing particular aspects and/or features is not described in any greater detail herein. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
