Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping equipment, and in particular relates to a special terrain auxiliary surveying and mapping device. Background Art

[0002] Special terrain area surveying, as the name implies, refers to those areas with complex terrain and diverse landforms. For example, mountainous areas, swamps, deserts, polar regions, etc. These areas often have unique geographical environments, such as plateau climate, low temperature and snow, wetland lakes, etc., which bring great challenges to surveying and mapping work, especially for the positioning function of the surveying and mapping device during operation. Due to the rugged terrain, in order to maintain the accuracy of surveying and mapping, the bottom of the surveying and mapping device needs to be sufficiently balanced and stable.

[0003] When the positioning structure at the bottom of the existing surveying and mapping device is placed on the ground with different height differences, each position needs to be adjusted separately (i.e., height adjustment). When the position is frequently changed during surveying and mapping, the positioning process will also take up a lot of operation time, reducing the overall surveying and mapping efficiency;

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a special terrain auxiliary surveying and mapping device. Utility Model Content

[0005] The purpose of the embodiment of the utility model is to provide a special terrain auxiliary surveying and mapping device, aiming to solve the above-mentioned problems.

[0006] The utility model is implemented as follows: a special terrain auxiliary surveying and mapping device comprises: a surveying and mapping instrument mounting platform and a surveying and mapping instrument body; the surveying and mapping instrument body is detachably mounted on the top of the surveying and mapping instrument mounting platform, two groups of support legs are mounted on both sides of the bottom of the surveying and mapping instrument mounting platform through U-shaped connecting brackets, the bottoms of the support legs are in contact with the ground to be surveyed and mapped, and are used to play a supporting role, a group of positioning hydraulic cylinders are fixedly mounted in the middle of the connecting bracket, and the bottom ends of the positioning hydraulic cylinders are connected to an adaptive positioning mechanism through a hydraulic rod, and the adaptive positioning mechanism is automatically adjusted and fixed on the ground when facing special terrains with different height differences under the driving lifting of the positioning hydraulic cylinder, so as to keep the surveying and mapping instrument mounting platform stable, and the adaptive positioning mechanism comprises a connecting block connected to the bottom end of the hydraulic rod, shaft rods are mounted on the bottoms of the front and rear sides of the connecting block, and a driving gear is rotatably connected between the bottom ends of the shaft rods on both sides through a rotating shaft, and at the same time, brackets are connected on both sides Two positioning lifting frames are symmetrically installed on the inner side of the bottom end, and the driving gear is placed in the middle of the positioning lifting frames on both sides. A slide plate is installed on the inner wall of the positioning lifting frame, and a slide plate is provided inside the slide plate, which runs through the upper and lower parts. A T-shaped slider is slidably connected inside the slide slot, and an adaptive rack is provided on the outer wall of the T-shaped slider. The adaptive racks on both sides are meshed with the driving gear at the same time. A positioning component is fixedly installed on the bottom of the T-shaped slider, and the positioning component is inserted under the ground for positioning. The positioning hydraulic cylinder is started to drive the hydraulic rod to drive the driving gear to descend, and then cooperate with the driving gear to mesh with the adaptive racks on both sides to drive the T-shaped slider to move downward. When the bottoms of the T-shaped sliders on both sides touch the ground at different heights, the driving gear rotates to drive the T-shaped sliders on both sides to have a longitudinal distance difference, thereby fixing the surveying instrument mounting platform while keeping it level, thereby improving the scope of application of the device.

[0007] The special terrain auxiliary surveying and mapping device provided by the utility model drives the driving gear to rise and fall by setting a positioning hydraulic cylinder, and then utilizes the driving gear to mesh with the adaptive racks on both sides, utilizes the meshing limit and meshing rotation of the driving gear and the adaptive rack, and adaptively controls the positioning rod at the bottom to perform insertion positioning with different terrains, thereby providing a convenient, effective and stable positioning function for the surveying and mapping of the surveying and mapping instrument body which frequently changes its position.

Two positioning lifting frames 16 are symmetrically installed on the inner side of the end, and the driving gear 19 is placed in the middle of the positioning lifting frames 16 on both sides. A slide plate 20 is installed on the inner wall of the positioning lifting frame 16. A slide plate 21 running through the upper and lower parts is opened inside the slide plate 20. A T-shaped slider 22 is slidably connected inside the slide groove 21. An adaptive rack 23 is arranged on the outer wall of the T-shaped slider 22. The adaptive racks 23 on both sides are meshed with the driving gear 19 at the same time. A positioning component is fixedly installed at the bottom of the T-shaped slider 22. The positioning component is inserted under the ground for positioning. The positioning hydraulic cylinder 15 is started to drive the hydraulic rod to drive the driving gear 19 to descend, and then cooperate with the driving gear 19 to mesh with the adaptive racks 23 on both sides to drive the T-shaped slider 22 to move downward. When the bottoms of the T-shaped sliders 22 on both sides contact the ground at different heights, the driving gear 19 rotates to drive the T-shaped sliders 22 on both sides to have a longitudinal distance difference, thereby fixing the surveying instrument mounting platform 10 while keeping it level, thereby improving the scope of application of the device.

[0016] In the embodiment of the utility model, the specific detachable installation method between the surveying instrument body 11 and the surveying instrument mounting platform 10 can be based on the commonly used connection installation method, which will not be described in detail here. At the same time, the type of the surveying instrument body 11 is determined according to the specific surveying direction, and specifically includes: GPS theodolite instruments for measuring horizontal angles and vertical angles, etc.;

[0017] Among them, the support leg 13 includes an electric telescopic rod fixed at the bottom of the connecting bracket 12, and a support plate 14 is installed at the bottom end of the electric telescopic rod. In the initial placement of the surveying instrument mounting platform 10, the height of the support plate 14 is adjusted by controlling the electric telescopic rod, and then the surveying instrument mounting platform 10 is stably placed using the support plates 14 on both sides. A plurality of protrusions are evenly installed at the bottom of the support plate 14 to increase the contact friction with the ground, thereby increasing the stability of the support plate 14 when it is placed.

[0018] In one example of the present invention, the positioning assembly includes a positioning rod base 24 installed at the bottom of the T-shaped slider 22, a mounting hole 25 is opened in the middle of the bottom of the positioning rod base 24, a mounting rod 26 is detachably installed inside the mounting hole 25, a positioning rod base plate 27 is connected to the bottom of the mounting rod 26, and a plurality of positioning rods 28 are evenly installed in a ring at the bottom of the positioning rod base plate 27. By utilizing the detachable connection between the mounting rod 26 and the mounting hole 25, it is convenient to select a suitable positioning rod 28 for cutting positioning according to the type of special terrain, that is, the connecting block 17 is used to drive the driving gear 19 to move up and down, control the lifting and lowering of the T-shaped sliders 22 on both sides, and then drive the positioning rod 28 to apply downward pressure to the contacted ground, and then through the cutting cooperation of multiple groups of positioning rods 28 with the ground, the surveying instrument mounting platform 10 is adaptively positioned;

[0020] Specifically, the bottom end of the positioning rod 28 is configured as a conical structure, so as to facilitate rapid insertion into the ground for fixation.

[0021] The above embodiment of the utility model provides a special terrain auxiliary surveying and mapping device. When in use, a suitable type of surveying and mapping instrument body 11 is selected and installed on the surveying and mapping instrument mounting platform 10. Then, according to the terrain to be surveyed, the electric telescopic rods on both sides are started to control the support plate 14 to contact the ground to place the surveying and mapping instrument mounting platform 10 horizontally. Then, the positioning hydraulic cylinder 15 is started to drive the connecting block 17 to move downward. At the same time, the engagement and limiting of the driving gear 19 and the adaptive racks 23 on both sides are used to synchronously drive the T-shaped sliders 22 on both sides to move downward. At this time, the positioning rods 28 at the bottom of the T-shaped slider 22 apply downward pressure to the contacted ground, and the positioning rods 28 are inserted under the ground. At the same time, when the positioning rods 28 on both sides are in contact with the ground with different height differences, the engagement and rotation of the driving gear 19 and the adaptive racks 23 on both sides are used to adjust the vertical height difference of the T-shaped sliders 22 on both sides, so that the positioning rods 28 at the bottom can be adaptively inserted into the ground for positioning according to the different heights of the ground, and then cooperate with the support plates 14 on both sides to provide stable surveying and mapping conditions for the surveying and mapping instrument mounting platform 10.
