Description

Technical Field

[0001] The invention relates to a surveying instrument, in particular to a ground level surveying instrument for urban planning surveying and mapping, belonging to the technical field of ground level surveying and mapping. Background Art

[0002] Urban planning and surveying projects often require the use of level surveying instruments. The work content is to measure space and terrain, and to organize and collect various information about space and terrain. Before and after the construction of the project, surveying engineers are required to measure the relevant projects to ensure the quality of the project. The existing measurement of the horizontality of the ground is generally carried out by using a ruler to measure in cross directions at the same position. If a gap appears under the ruler, it proves that the ground is uneven. This measurement method is complicated to operate.

[0003] In a Chinese patent with application number CN202120373005.4, a ground levelness surveying instrument for urban planning surveying is proposed. Liquid is mainly injected into a water tank. The liquid enters a transparent ring through a first pipe, and a horizontal rod is used to observe whether the liquid levels on both sides of the transparent ring are at the same height. When they are at the same height, it indicates that the bottom plate is in a horizontal state. Then observe whether the arrow is at the 0 scale of the scale. If so, it means that the levelness surveying operation can be carried out directly. If not, the second threaded sleeves on both sides are rotated, and the fourth support plate is pushed to rotate by the threaded rod until the arrow is at the 0 scale of the scale. Then, surveying is carried out. Although it has the function of levelness surveying, it can only detect the levelness of a single height, and the functions are not diverse enough.

[0004] In a Chinese patent with application number CN202122864585.X, a ground levelness surveying instrument for urban planning surveying is proposed. The instrument drives the turntable to rotate inside the limit sleeve by rotating the vertical rod, and the spring pin is continuously stuck in the limit hole, which can play an elastic limiting role, thereby facilitating the angle adjustment of the levelness surveying instrument body and realizing ground levelness measurement at different angles. However, the instrument cannot detect the height difference of structures with height difference, and its functionality is also weak, with only a simple levelness measurement function.

[0005] The present invention is proposed in view of the above. Summary of the invention

[0006] The object of the present invention is to provide a ground levelness surveying instrument for urban construction planning and surveying, which can emit laser rays around the present invention through a mobile and layering indicating mechanism, and use each laser ray to indicate the horizontal position at the same height to achieve the basic levelness detection function. Moreover, since the laser direct lamps of each mobile and layering indicating mechanism are all movable structures, the levelness of structures in different directions can be detected. At the same time, there are laser direct lamps at different heights, which can detect the levelness difference of structures at different heights. It is simple to use and meets diverse usage requirements. The cooperation of the ground dust scraping component and the rotary distance measuring and marking integrated mechanism, on the one hand, simply cleans the ground dust through the ground dust scraping component, and then uses the rotary distance measuring and marking integrated mechanism to spray paint on the ground for marking, with more diverse functions. On the other hand, the rotary distance measuring and marking integrated mechanism can detect the distances below and above, and can play the role of detecting whether the building is flat.

[0007] The present invention realizes the above object through the following technical solutions. A ground levelness surveying instrument for urban construction planning and surveying includes a transportation and installation seat, a lifting and adjusting rod, a universal ball seat, a horizontal calibration disk, an annular installation frame, a ground dust scraping component, a rotary distance measuring and marking integrated mechanism, and a mobile and layering indicating mechanism. The lifting and adjusting rod is fixedly installed at the top center position of the transportation and installation seat.

An expansion and inflation airbag is arranged on the outer side of the transportation and installation seat. A water storage cavity is arranged on the top of the horizontal calibration disk.

[0008] During the actual use of the present invention, the cooperation of the transportation and installation seat and the expansion and inflation airbag can wrap other components. Only an external sealing cover is needed on the top of the expansion and inflation airbag, which is convenient for transporting the whole present invention. During the use process, the lifting and adjusting rod controls the height adjustment of the horizontal calibration disk, and the universal ball seat is used to adjust the horizontal calibration disk, so that the horizontal calibration disk can be used for leveling, thereby facilitating the measurement of levelness and the precise use of the rotary distance measuring and marking integrated mechanism and the mobile and layering indicating mechanism.

[0009] By means of a mobile and layerable indicating mechanism, laser rays are emitted around the present invention, and each laser ray is used to indicate the horizontal position at the same height to achieve the basic level detection function. Moreover, since the laser direct lamps of each mobile and layerable indicating mechanism are all movable structures, the level detection can be carried out for structures in different orientations. At the same time, there are laser direct lamps at different heights, which can detect the level difference of structures at different heights. It is simple to use and meets diverse usage requirements at the same time.

[0013] Preferably, in order to enable the rotation of the rotary fixing base to control the flipping of the infrared rangefinder and the paint tank, the infrared rangefinder is used to achieve the ranging function.

The peristaltic pump is fixedly installed on the outer wall of the paint tank, and the discharge conduit is fixedly penetrated through the paint tank and communicated with the inner cavity of the paint tank. The discharge conduit is penetrated through the driving end of the peristaltic pump.

[0014] Preferably, in order to enable the rotation of the servo motor to drive the rotary screw to rotate, and the sliding block cannot rotate, so that the sliding block is pushed to move by the rotary screw to realize the movement control of the sliding block. The mobile and layering indicating mechanism includes a servo motor, a rotary screw, a connecting shaft and a sliding block. The servo motor and the connecting shaft are respectively arranged at both ends of the inner wall of the strip-shaped chute. One end of the rotary screw is connected to the output shaft of the servo motor, and the other end of the rotary screw is rotatably arranged in the strip-shaped chute through the connecting shaft. The sliding block is slidably arranged in the strip-shaped chute, and the sliding block is threadedly connected to the rotary screw.

[0015] Preferably, in order to enable the movement of the sliding block to adjust the positions of the indicating board and the laser direct light lamp, so that the laser direct light lamp can flexibly adjust its position for indicating the levelness of structures in different directions, and can also control the laser direct light lamps at different heights to be turned on for directly indicating structures at different heights. The mobile and layering indicating mechanism further includes an indicating board and a laser direct light lamp. The indicating board is welded to the side wall of the sliding block, and the laser direct light lamp is arranged on the outer wall of the indicating board, and the vertical distance between each laser direct light lamp is 1 cm.

[0016] The beneficial effects of the present invention are as follows: The present invention emits laser rays around the present invention through the mobile and layering indicating mechanism, and uses each laser ray to indicate the horizontal position at the same height to achieve the basic levelness detection function. And since the laser direct light lamps of each mobile and layering indicating mechanism are all movable structures, the levelness of structures in different directions can be detected.
