The mapping science is the theory and technical discipline of researching and measuring and calculating the geometric position, the shape and the gravitational field of the earth, measuring the natural shape of the earth surface and the geometric distribution of artificial facilities according to the geometric position, the shape and the gravitational field of the earth, and combining certain social information and the geographic distribution of the natural information to compile maps and thematic maps of various scales in the global and local areas. Mapping includes two main things, measurement and mapping. Mapping has wide application in economic construction and national defense construction. In urban and rural construction planning, homeland resource utilization, environmental protection and other works, various maps for land measurement and mapping must be performed for planning and management. In the construction of geological exploration, mineral exploitation, water conservancy, traffic, etc., control measurement, mine measurement, route measurement and topographic map drawing are necessary for geological survey and various building design construction.
The prior surveying and mapping device mainly comprises a surveying and mapping part with a horizontal scale and a vertical scale and a triangular support frame, wherein the triangular support frame mainly plays a role in supporting and stabilizing the surveying and mapping part. Because three stabilizer blade is usually directly arranged in the surface of soil, and many local top layer soil is comparatively soft, consequently accomplish the back to the support of surveying and mapping device, personnel's walk will lead to the change of top layer soil, and the mapping portion easily takes place the slope, influences the degree of accuracy of survey and drawing.
Disclosure of Invention
The invention aims to provide a land mapping device which is used for stably supporting a mapping part.
In order to achieve the above purpose, the basic scheme of the invention is as follows:
the soil mapping device sequentially comprises a mapping part, a supporting rod, a base and a fixing part from top to bottom, wherein the mapping part comprises a horizontal dial and a vertical dial, the mapping part is arranged at the upper end of the supporting rod, the lower end of the supporting rod is fixed on the base, the fixing part comprises a fixing rod fixed on the bottom surface of the base, the lower end of the fixing rod is conical, a pressure cavity is arranged in the fixing rod, a limiting pin capable of sliding along the radial direction of the fixing rod is arranged on the fixing rod, and a pressure spring which enables the limiting pin to receive elasticity towards the pressure cavity is sleeved on the limiting pin; an opening is arranged on the side wall of the fixed rod, which is positioned below the limiting pin, and the opening is closed by an elastic layer; when the pressure in the pressure cavity is increased, the limiting pin extends outwards and the elastic layer expands; the support rod is internally provided with a piston cavity, a piston is arranged in the piston cavity, a crank is rotationally connected above the piston cavity, the crank is connected with the piston through a connecting rod, the crank, the piston and the connecting rod form a crank slide block mechanism, and the support rod is also provided with an air inlet one-way valve, one end of which is communicated with the piston cavity and can suck air from the outside, and an air outlet one-way valve which can charge air to the pressure cavity.
The principle of this scheme soil survey and drawing device lies in:
when the soil mapping device is fixed, the fixing rod is inserted into soil until the base is in contact with the soil, and then the position of the whole device is adjusted through the supporting rod, so that the mapping part is in a horizontal state, and mapping is facilitated. After the position of the surveying and mapping part is adjusted, the supporting rod is held to stabilize the position of the surveying and mapping part, and the crank is rotated at the same time; because crank, connecting rod and piston constitute slider-crank mechanism, consequently in the continuous in-process of rotating the crank, the piston will slide in the piston chamber back and forth to make piston chamber, piston, inlet check valve and go out the air check valve and form the inflator structure, consequently the piston chamber will constantly aerify to the pressure chamber, thereby makes the pressure in the pressure chamber increase.
Along with the continuous increase of pressure in the pressure chamber, the pressure in the pressure chamber will produce thrust to the spacer pin to make the spacer pin overcome the elasticity of pressure spring and outwards stretch out, consequently the spacer pin will insert in the soil of dead lever periphery, further plays the stabilization to the base. In addition, along with the increase of pressure in the pressure chamber, the elastic layer will outwards expand, expand to the elastic layer will extrude the soil around, makes elastic layer and soil contact inseparabler, therefore the frictional force of elastic layer and soil is also bigger, can further play the stabilization to the base.
The beneficial effect that this scheme produced is:
firstly, the current surveying and mapping device is usually supported by three supporting feet, and in order to facilitate the adjustment of the position of the surveying and mapping device, the three supporting feet are usually directly placed on the surface of soil; the surface soil in many places is softer, so that after the support of the surveying and mapping device is completed, the surveying and mapping device is quickly inclined due to the change of the surface soil caused by the walking of personnel; in the device, the fixing rod can be inserted into deep soil, and after the fixing rod is inserted into the soil, the limiting pin extends out and is inserted into the soil around the fixing rod, and the fixing rod can enable the base and the soil to form a firmer connection relationship because the deep soil is more compacted; in addition, the limiting pin is inserted into the soil, so that the base can be prevented from being inclined.
And (II) the elastic layer expands to enable the elastic layer to be in closer contact with the soil, so that the friction force between the elastic layer and the soil is larger, and the base is further stabilized.
And thirdly, the limiting pin is inserted into the soil, and the elastic layer is expanded, so that the fixing rod is not easy to pull out from the soil, and the phenomenon that the surveying and mapping device is damaged due to tilting caused by misoperation can be avoided.
Fourthly, after the pressure of the pressure cavity is increased, the elastic layer expands to push the soil at the periphery of the fixing rod outwards; therefore, the elastic layer is contracted by releasing the pressure in the pressure cavity, and a gap is formed between the soil and the elastic layer, so that the fixing rod is conveniently pulled out of the soil.
The first preferred scheme is as follows: as a further optimization of the basic scheme, a baffle is arranged in the fixed rod, and a positioning pin is arranged in the baffle; the both sides of baffle are equipped with the slide, and the slide includes the top slide and the lower slide of mutual fixed, the pressure chamber is enclosed by top slide, lower slide, dead lever's lateral wall and baffle, and the below of lower slide is equipped with the pressure spring that offsets with lower slide, is fixed with the lower depression bar that extends to in the bracing piece on the top slide, is equipped with the bar groove along vertical direction on the lateral wall of bracing piece, is equipped with the handle that stretches out from the bar groove on the lower depression bar, is equipped with the limit structure that can be spacing to the lower depression bar on the bracing piece.
In the first preferred embodiment, since the pressure chamber is defined by the upper slide plate, the lower slide plate, the side wall of the fixing rod and the partition plate, the upper slide plate and the lower slide plate are fixed to each other, and the upper slide plate and the lower slide plate can slide in the fixing rod, that is, the position of the pressure chamber in the fixing rod can be changed. In the scheme, when the lower compression bar is not subjected to external force, the upper sliding plate and the lower sliding plate are positioned at the upper end of the fixed bar under the action of the pressure spring, namely the pressure cavity is positioned at the upper end of the fixed bar, so that the pressure cavity is not opposite to the limiting pin and the elastic layer; at the moment, the crank is rotated to increase the pressure in the pressure cavity, and when the pressure in the pressure cavity reaches a certain value, the pressure rod is pressed down by the handle, so that the pressure cavity slides to a position opposite to the limiting pin and the elastic layer; the limiting pin is subjected to pressure of the pressure cavity, and the force applied to the limiting pin suddenly increases, so that the limiting pin can quickly obtain a larger speed to be pricked into the soil, and the limiting pin can be rolled deeper in the soil more favorably, so that a better stabilizing effect is achieved on the base.
And a second preferred scheme is as follows: as a further optimization of the first preferred scheme, the upper end of the lower pressure rod extends into the piston cavity, an air passage is arranged in the lower pressure rod, one end of the air passage extends into the piston cavity, the other end of the air passage extends into the pressure cavity, and the air outlet one-way valve is arranged in the air passage. An air passage is arranged in the lower pressure rod, the lower pressure rod extends into the piston cavity, and the air outlet one-way valve is arranged in the air passage, so that the pipeline arrangement can be reduced, and the installation is more facilitated.
And a preferred scheme III: as a further optimization of the second preferred scheme, the periphery of the lower pressure rod is provided with a ring groove, the handle is clamped in the ring groove, the handle is rotationally connected with the lower pressure rod, and the lower part of the strip-shaped groove is provided with a clamping groove into which the handle can be clamped. The handle is clamped in the annular groove, so that the handle can only rotate relative to the lower pressure rod, and the lower pressure rod can slide downwards by pressing the handle. After the lower pressure rod drives the upper slide plate and the lower slide plate to slide to the positions of the limiting pins and the elastic layers, the handle is rotated into the clamping groove, so that the lower pressure rod can be limited, namely the pressure cavity is limited.
The preferable scheme is as follows: as a further optimization of the third preferred aspect, the pressing rod penetrates through the piston; the pressure applied to the periphery of the lower pressure rod is the same under the condition that the pressure in the pressure cavity is increased, so that the lower pressure rod can be prevented from sliding downwards due to the fact that the upper end face of the lower pressure rod is subjected to the pressure in the pressure cavity.
The preferable scheme is as follows: as a further optimization of the fourth preferred scheme, the base is connected with adjusting rods in a threaded mode, and the adjusting rods are uniformly distributed on the periphery of the fixing rod along the circumferential direction of the base. The adjusting rod has a certain supporting effect on the seat body, and the inclination and the like of the seat body can be adjusted by screwing the adjusting rod; therefore, after the fixing rod is inserted into the soil, the position of the seat body can be conveniently adjusted by screwing the adjusting rod.

A pressure spring 36 which is propped against the lower slide plate 32 is arranged below the lower slide plate 32, and the pressure cavity 34 is pushed to the uppermost end of the inner cavity of the fixed rod 30 under the action of the pressure spring 36; by applying downward pressure to the upper slider 31, the pressure chamber 34 can be moved downward against the elastic force of the compression spring 36.
The middle part of baffle 33 is equipped with spacer pin 38, spacer pin 38 and baffle 33 sliding connection, and spacer pin 38 sets up along the width direction of baffle 33. When the pressure chamber 34 is uppermost within the fixed rod 30, the lower slide 32 is positioned above the stop pin 38. An opening is provided in the side wall of the fixing lever 30 below the stopper pin 38, the opening being sealed by the elastic layer 35, and the elastic layer 35 in this embodiment is made of high-strength rubber. In addition, the partition 33 is provided with air holes 37, the air holes 37 penetrate through two side surfaces of the partition, and one end of a limiting pin 38 extends into the air holes 37; and a pressure spring is sleeved on the limiting pin 38, and the pressure applied by the pressure spring to the limiting pin 38 faces the middle part of the partition plate 33.

The upper end of the lower compression bar 40 extends into the support bar 20; a piston cavity 21 is arranged in the support rod 20, and a piston 22 capable of sliding up and down is arranged in the piston cavity 21; the upper end of the supporting rod 20 is rotatably connected with a crank 24, the crank 24 is connected with the piston 22 through a connecting rod 23, the upper end of the connecting rod 23 is hinged with the crank 24, and the lower end of the connecting rod 23 is hinged with the piston 22; so that the crank 24, the connecting rod 23 and the piston 22 form a crank slide block mechanism, i.e. the crank 24 rotates to drive the piston 22 to slide back and forth in the piston cavity 21. The depression bar 40 extends into the piston cavity 21, and the depression bar 40 penetrates the piston 22; an air passage 26 is arranged in the lower pressure rod 40, the upper end of the air passage 26 is communicated with the piston cavity 21, the lower end of the air passage 26 is communicated with the pressure cavity 34, an air outlet one-way valve 27 is arranged in the air passage 26, and an air inlet one-way valve 25 is arranged on the side wall of the piston cavity 21, so that the piston 22 and the piston cavity 21 form an inflator mechanism; when the piston 22 reciprocates in the piston chamber 21, the piston chamber 21 will be filled with gas into the pressure chamber 34 through the gas outlet check valve 27, so that the pressure in the pressure chamber 34 is continuously increased.
The side wall of the support rod 20 is provided with a bar-shaped groove 28 along the vertical direction, and the lower pressure rod 40 is rotatably connected with a handle 41 extending from the bar-shaped groove 28. The periphery of the lower pressure rod 40 is provided with a ring groove, and the handle 41 is clamped in the ring groove through a lantern ring, so that the handle 41 and the lower pressure rod 40 form rotary connection; the clamping groove 29 is arranged at the lower part of the bar-shaped groove 28, the pressing rod 40 is pressed down by the handle 41, when the handle 41 moves to the clamping groove 29, the handle 41 is rotated into the clamping groove 29, so that the upward movement of the pressure cavity 34 under the action of the pressure spring 36 can be avoided; i.e. the handle 41 is snapped into the catch 29 and can limit the pressure chamber 34.
In addition, three adjusting rods 11 are connected to the base 10 through threads, and the adjusting rods 11 are uniformly distributed on the periphery of the fixing rod 30 along the circumferential direction of the base 10. By screwing the adjustment lever 11, the inclination of the seat body and the like can be adjusted.
The concrete working process of the land mapping device of the embodiment is as follows:
when the soil mapping device is fixed, the fixing rod 30 is inserted into the soil until the base 10 contacts the soil, and then the position of the whole device is adjusted by the adjusting rod 11 so that the mapping part is in a horizontal state. The support rod 20 is then held to stabilize the position of the mapping section while the crank 24 is rotated, and the piston chamber 21 will continuously inflate into the pressure chamber 34, thereby increasing the pressure in the pressure chamber 34.
When the pressure of the pressure cavity 34 reaches a certain value, the handle 41 is used for pressing down the pressing rod 40, so that the pressure cavity 34 slides to a position opposite to the limiting pin 38 and the elastic layer 35; the limiting pin 38 is pressed by the pressure cavity 34, so that the force applied by the limiting pin 38 is suddenly increased, and the limiting pin 38 is quickly pricked into the soil to stabilize the base 10. In addition, the pressure in the pressure cavity 34 will expand and expand the elastic layer 35 outwards, so that the elastic layer 35 will squeeze the surrounding soil, so that the elastic layer 35 contacts with the soil more tightly, and the friction force between the elastic layer 35 and the soil is larger, so that the base 10 can be further stabilized. When the handle 41 slides to the lower end of the bar-shaped groove 28, the handle 41 is clamped into the clamping groove 29, so that the fixing of the soil mapping device is completed.
When the soil mapping device needs to be dismantled, the handle 41 is rotated out of the clamping groove 29, so that the clamping groove 29 does not have a limiting effect on the pressing rod 40 any more, the pressure cavity 34 is reset under the action of the pressure spring 36, the elastic layer 35 and the limiting pin 38 are not opposite to the pressure cavity 34 any more, the elastic layer 35 is contracted, the limiting pin 38 is reset under the action of the pressure spring 36, and the fixing rod 30 can be pulled out of the soil.
