[0002] Land surveying is an important link in the fields of engineering construction and geological survey, and usually needs to use precise equipment such as a total station or a level to carry out topographic mapping and soil analysis. In the actual surveying process, the stability of the equipment support directly affects the accuracy of data acquisition, especially in complex terrain (such as slopes, soft soil and narrow mines) in the wild, the support needs to have the ability of rapid leveling, anti-overturning and portable movement. The existing surveying equipment support mostly adopts a tripod or a fixed base structure, which can meet the needs of general flat terrain, but still needs to rely on manual leveling or additional reinforcement when facing irregular ground, and the operation efficiency is low. In addition, with the diversification of surveying scenes, higher requirements are put forward for the adaptability, automation degree and environmental compatibility of the support.

[0003] At present, the traditional support is difficult to be quickly adjusted to a horizontal state on an inclined, soft or narrow ground, resulting in unstable equipment erection; and lacks an automatic counterweight anti-overturning mechanism, relies on manual estimation and transportation of counterweight blocks, and is time-consuming and labor-consuming; in addition, increasing the base area can improve the stability, but will sacrifice the portability, and cannot meet the operation needs in narrow space; and manual adjustment of the support leg is difficult to accurately match the ground inclination, and is easy to cause equipment deviation or vibration, therefore, in view of the above status, it is urgent to develop a portable land surveying equipment to overcome the deficiencies in current actual application.

DETAILED DESCRIPTION

[0061] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0062] The specific implementation of the present application will be described in detail below in combination with specific embodiments.

[0063] Please refer to Figures 1-14 The portable land surveying equipment provided by the embodiments of the present application comprises a surveying equipment erecting frame 3, the land surveying equipment is detachably installed on the surveying equipment erecting frame 3, and further comprises:

[0064] A support base assembly 1 is connected with the surveying equipment erecting frame 3 through a multi-angle adjustment assembly 2, the multi-angle adjustment assembly 2 is used to keep the surveying equipment erecting frame 3 always vertical and downward and drive the support base assembly 1 to be in parallel contact with the ground at any inclination angle;

[0065] The support base assembly 1 comprises a polygon control seat 4, a supporting seat 7, a counterweight anti-tilting structure and a control system, the supporting seat 7 is fixedly installed on the polygon control seat 4 and connected with the multi-angle adjustment assembly 2;

[0066] A plurality of the counterweight anti-tilting structures are uniformly distributed in the polygon control seat 4, the control system is located in the middle part of the supporting seat 7, and the control system is used to automatically control the specified counterweight anti-tilting structure in the corresponding tilting direction to act according to the tilting state of the polygon control seat 4 and the supporting seat 7, so as to realize the purpose of accurately maintaining the stable operation of the whole equipment.

[0067] Also included is a telescopic mounting rack 20 fixedly mounted at a middle position of the survey equipment mounting rack body 3, and a top end of the telescopic mounting rack 20 is detachably mounted with a land survey equipment;

[0068] The telescopic mounting rack 20 is used to adjust the height of the land survey equipment from the ground according to the requirements of land survey.

[0069] In the process of land survey, first, the equipment can be moved to the designated survey location, and according to the topography of the survey location (such as irregular inclined ground, soil soft area or narrow (mine, etc.) area, etc.), the survey equipment erecting frame 3 can be held by the relevant staff, and the angle of the polygonal control seat 4 and the supporting seat 7 can be adjusted through the multi-angle adjusting assembly 2 (wherein the side length of the polygonal control seat 4 can be 0.8-1.2 m, so as to balance portability and stability), so that it is in parallel contact with the ground. At this time, the survey equipment erecting frame 3 is still in the vertical state. Because the contact area of the polygonal control seat 4 with the ground is large and the size is limited, it can cope with the soil soft and narrow area, and under the adjusting action of the multi-angle adjusting assembly 2, the polygonal control seat 4 can be completely fitted with the ground with different inclination degrees and inclination directions, so as to achieve the supporting effect. In order to further ensure the stability of the polygonal control seat 4 on the ground (avoiding the whole equipment from falling due to the deviation of the whole equipment gravity center), when the polygonal control seat 4 is placed on the ground with a certain inclination degree, the control system is started, wherein the control system can be started manually by the staff. Under the control of the control system, the specified counterweight anti-tilt structure in the corresponding inclination direction will act, that is, the counterweight anti-tilt structure on the upper side of the inclined polygonal control seat 4 will act, while the counterweight anti-tilt structure on the lower side of the inclined polygonal control seat 4 will not act. On the one hand, it can save resources and achieve the purpose of accurately maintaining the stability of the whole equipment, on the other hand, it can save space and adapt to more complex terrain (such as the area where not all counterweight anti-tilt structures on the polygonal control seat 4 can smoothly act), and it is convenient for the staff to quickly maintain the stability of the whole equipment. Of course, all counterweight anti-tilt structures can be manually controlled to act according to the topography conditions of the survey, so as to fully ensure the stability of the whole equipment during the survey. After the corresponding counterweight anti-tilt structure acts, the counterweight block (such as lead block) carried by the staff can be placed in the counterweight anti-tilt structure to ensure the stability of the whole equipment. Then, the equipment needed for survey can be installed on the telescopic mounting frame 20 (such as total station, level and weather station, etc., which can adapt to various types of survey equipment, the lifting range of the telescopic mounting frame 20 is 1.5-2.5 m, and the maximum bearing weight is 50 kg), and the height of the land survey equipment from the ground can be adaptively changed through the lifting of the telescopic mounting frame 20, so as to smoothly survey the purpose. The operation is simple, not only can adapt to various terrain conditions for surveying, meet the increasingly complex actual needs, but also can fully ensure the stability of the equipment during the whole survey process, and the equipment deployment / storage time is ≤5 min, the counterweight installation time is ≤30 s, the operation is convenient, and the staff is provided with convenience.

[0081] And three driving parts 28 are connected with the survey equipment erecting frame body 3 through three fixed supports 29 respectively, three driving parts 28 are also located between the survey equipment erecting frame body 3 and the supporting circular ring seat 24.

[0082] When the inclination angle of the polygonal control seat 4 and the support seat 7 needs to be adjusted, one of the survey personnel manually holds the survey equipment erecting frame body 3, and the other survey personnel moves the driving part 28 manually or intelligently, wherein the driving part 28 can adopt the form of a toothed plate and can be driven to reciprocate by a telescopic cylinder, at this time, the driven part one 30, the driven part two 31 and the driven part three 32 can all adopt the form of a gear, then in the process of moving the driving part 28, the corresponding gear is driven to rotate, then in the process of rotating the gear, the rotating cylinder 25, the rotating sleeve one 26 or the rotating sleeve two 27 are synchronously rotated, thereby driving the adjustment transmission leg one 21, the adjustment transmission leg two 22 or the adjustment transmission leg three 23 to move, in the process of moving the adjustment transmission leg one 21, the adjustment transmission leg two 22 and the adjustment transmission leg three 23 (for example, in the process of rotating the rotating sleeve two 27, the rotating cylinder 25 and the rotating sleeve one 26 remain stationary, then the rotating sleeve two 27 generates a pulling force on the adjustment transmission leg two 22 and pulls the adjustment transmission leg two 22 to move upward, at this time, under the limiting action of the adjustment transmission leg one 21 and the adjustment transmission leg three 23, the adjustment transmission leg two 22 drives one side of the support seat 7 to tilt, similarly, by moving the adjustment transmission leg one 21, the adjustment transmission leg two 22 and the adjustment transmission leg three 23 to different heights or moving them alone by a certain height, the support seat 7 and the polygonal control seat 4 can be tilted at any angle, thereby being suitable for different terrain conditions, especially terrain with different inclination angles and inclination directions, which will not be described in detail here), the polygonal control seat 4 and the support seat 7 can be tilted, of course, the driving part 28, the driven part one 30, the driven part two 31 and the driven part three 32 can also adopt the transmission mode of a worm gear matched with each other, and the driving part 28 (worm) is driven to rotate by a motor, thereby driving the three worm gears to rotate simultaneously or to different degrees, thereby realizing the adjustment of the inclination angle of the polygonal control seat 4 and the support seat 7, and the response time is ≤5 s from the horizontal to the maximum inclination angle adjustment.

[0083] In an embodiment of the present application, please refer to Figures 1-14 , the counterweight anti-tilting structure comprises:

[0084] The counterweight pull-out boxes 5 are a plurality of, and the plurality of counterweight pull-out boxes 5 are respectively inserted into a plurality of sliding cavities formed on the polygonal control seat 4, when the land survey equipment works on a flat road surface, the plurality of counterweight pull-out boxes 5 are retracted into the sliding cavities;

[0085] and the magnetic sliding plate 13 is fixedly installed at the end of the counterweight pull-out box 5 and is in sliding connection with the inner wall of the sliding cavity, and the magnetic sliding plate 13 is also in separable connection with an electromagnet arranged at the end of the sliding cavity, and the electromagnet is in electrical connection with the control system;

[0086] When the counterweight pull-out box 5 is retracted in the sliding cavity, the control system controls the electromagnet to be powered off and lose magnetism, at this time, the magnetic slide plate 13 and the electromagnet generate magnetic attraction force, and the magnetic slide plate 13 is pushed to the electromagnet.

[0087] When the designated counterweight pull-out box 5 needs to extend outside the sliding cavity, the control system controls the electromagnet to be powered on and generate magnetism, at this time, the magnetic slide plate 13 and the electromagnet generate magnetic repulsion force, and the magnetic slide plate 13 is pushed to the electromagnet.

[0088] The control system comprises:

[0089] A polygonal control box 12 is fixedly installed in the middle of the support seat 7, and a plurality of rhombic compartments 15 are uniformly distributed in the polygonal control box 12, and the top of the rhombic compartment 15 is provided with a transparent glass cover.

[0090] An electromagnetic control part 18 is fixedly installed in the middle of the polygonal control box 12.

[0091] A plurality of magnetic spheres 16 are equal in number to the number of the rhombic compartments 15, and the plurality of magnetic spheres 16 are respectively located in the plurality of rhombic compartments 15.

[0092] And a plurality of pressure detectors 17 are fixedly installed in the plurality of rhombic compartments 15 and located at one end of the rhombic compartment 15 away from the electromagnetic control part 18.

[0093] Further comprising: a plurality of anti-skid strips 14 are uniformly distributed in the counterweight pull-out box 5.

[0094] Wherein, the bottom of the end of the counterweight pull-out box 5 away from the polygonal control seat 4 is further provided with a protrusion for contacting the ground.

[0095] After the position of the polygonal control seat 4 is adjusted by the multi-angle adjustment component 2, the control system can be manually started. Before starting, the electromagnetic control unit 18 generates a magnetic force when energized, which attracts multiple magnetic spheres 16 to one end of the rhomboid compartment 15. When the power supply to the electromagnetic control unit 18 is manually disconnected, the multiple magnetic spheres 16 will roll inside the rhomboid compartment 15 under their own weight. Due to the different tilt directions of the polygonal control seat 4 and the support seat 7, some of the magnetic spheres 16 will roll towards... The support base 7 rolls downwards within the rhomboid compartment 15, while the magnetic spheres 16 at the upper position remain stationary against the electromagnetic control unit 18. The bottom wall of the rhomboid compartment 15 is inclined, meaning the height of the bottom wall at the end of the rhomboid compartment 15 furthest from the electromagnetic control unit 18 is slightly higher than the height of the bottom wall at the end closest to the electromagnetic control unit 18. This allows the polygonal control base 4 to remain stationary even when the electromagnetic control unit 18 is de-energized (saving energy) during surveying operations on a flat surface. The magnetic spheres 16 will concentrate around the electromagnetic control unit 18. At this time, the anti-tilting structure does not need to be activated. In addition, whether the magnetic spheres 16 are concentrated around the electromagnetic control unit 18 can also determine whether the ground is flat enough, which is helpful for relevant surveyors to make manual adjustments. This will not be elaborated on here. As one or more magnetic spheres 16 roll downward on the lower side of the inclined support 7, because the middle of the rhomboid compartment 15 is a bent structure, within the rhomboid compartment 15 which is not completely in the same direction as the inclined ground, the rhomboid compartment 15... The bend in the middle prevents the magnetic sphere 16 from moving further downward. Therefore, only the magnetic sphere 16 within the rhomboid compartment 15, which is completely aligned with the downward-facing slope of the inclined surface, can reach the other end of the rhomboid compartment 15 and contact the pressure detector 17. At this point, under the pressure of the magnetic sphere 16 on the pressure detector 17, the designated counterweight pull-out box 5 in the opposite direction can extend out of the sliding cavity (i.e., only the counterweight pull-out box 5 completely aligned with the upward-facing slope of the inclined surface moves; others do not move; the maximum counterweight load of a single counterweight pull-out box 5 is 30). Under the control of pressure detector 17, the designated electromagnet will be energized (others will not be energized, maintaining the static state of magnetic attraction), and will generate a magnetic repulsive force on the designated magnetic slide plate 13, thereby pushing the counterweight pull-out box 5 to move outward of the slide cavity. The counterweight pull-out box 5 is equipped with anti-slip strips 14 (made of neoprene rubber) to facilitate the movement of the counterweight within the box. Furthermore, after the counterweight pull-out box 5 moves to the outside of the slide cavity, the protrusion at the end of the counterweight pull-out box 5 contacts the ground (e.g., ...). Figure 4The convex can form support to the counterweight pull box 5, and can limit the position when the counterweight pull box 5 enters the slide cavity. With the assistance of the counterweight (after the magnetic ball 16 rolls to trigger the pressure detector 17, the response time is less than or equal to 2 seconds), the device can resist the shaking under the wind speed of 8 levels (18 m / s), and can automatically keep vertical when the slope is less than or equal to 25 degrees.

[0096] In an embodiment of the present application, referring to Figures 1-14 Further comprising: a plurality of bending supports 8, which are uniformly distributed on the support base 7;

[0097] A side support rod 9, one end of which is rotatably connected with the bending support 8, and the other end of which is fixedly installed with an anti-skid support ball 10;

[0098] And a positioning member 19, which is fixedly installed on the bending support 8 and is separably connected with the side support rod 9.

[0099] Further comprising: a signal transmitter 11, which is fixedly installed on the side support rod 9;

[0100] And a position detector 6, which is fixedly installed on the side wall of the support base 7, and is in a collinear state with the signal transmitter 11 when the bending side support rod 9 and the anti-skid support ball 10 are in contact with the ground.
