Description

Technical Field

[0001] The present invention belongs to the technical field of surveying tools, and particularly relates to a portable engineering surveying and mapping device for surveying. Background Art

[0002] Surveying and mapping is a working process in which staff measure data through certain instruments and draw maps. In surveying and mapping work, the use of surveying instruments is essential. During the use of surveying instruments, they need to be installed on a positioning frame. Currently, most of the positioning frames in use are ordinary tripods, and the positioning effect needs to be strengthened.

[0003] The existing tripod adopts a telescopic structure for the legs. The friction between the tip of the tripod bottom and the ground is small, and the legs are prone to sliding and displacement. Moreover, when using surveying tools, it is necessary to manually level the three base screws, making it difficult to control the leveling angle. Especially in measurement environments with slopes and uneven ground, it is laborious and time-consuming, and the measurement stability is also affected to a certain extent, making it inconvenient to operate. In addition, when the staff adjusts the height of the surveying instrument, the angle often changes simultaneously, increasing the working intensity of adjusting the height and angle of the surveying instrument. Summary of the Invention

[0004] In order to make up for the deficiencies of the prior art, ensure that the surveying and mapping device is stably placed on the ground, not prone to displacement and sliding, and is conducive to leveling the angle of the surveying and mapping device, reducing the working intensity of the staff in adjusting the surveying instrument, the present invention provides a portable engineering surveying and mapping device for surveying.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: The present invention relates to a portable engineering surveying and mapping device for surveying, including a mounting base, support legs, and a surveying instrument. The lower surface of the mounting base is hinged with support legs. There are multiple support legs on the mounting base, and the support legs are evenly distributed around the center of the mounting base. At least three support legs are provided. The upper surface of the mounting base is equipped with a surveying instrument, including:

[0006] An adjusting mechanism, which is installed at the lower end of the support leg. The adjusting mechanism contacts the ground after the support leg stands on the ground. The adjusting mechanism is used to improve the stability of the surveying device during use;

[0007] The adjusting mechanism includes an airbag, which is installed at the end of the support leg away from the mounting base. The lower end of the support leg contacts the ground prior to the lower surface of the airbag. The airbag is provided with an inflation port, and a valve is provided on the inflation port of the airbag. The airbag is inflated through a trachea connected to any one of an external manual air pump, a bicycle pump, and an electric air pump.

[0008] Preferably, a baffle is installed at the lower end of the support leg, and the lower surface of the baffle contacts the upper surface of the airbag;

[0009] The baffle is connected to the support feet by threads.

[0010] Preferably, the air bags are interconnected through air pipes. The air pipes for connection are hidden inside the support feet, and the air pipes in different support feet are connected to each other through detachable joints.

[0011] Preferably, a protective layer is covered on the lower surface of the air bag. The protective layer is made of silica gel material, and micro-grooves are uniformly formed on the surface of the protective layer.

[0012] Preferably, a micro-rod is installed inside the air bag. One end of the micro-rod passes through the air bag into the protective layer. An installation crack is formed on the protective layer, and the micro-rod is located in the installation crack. After the air bag is inflated and expanded, the installation crack unfolds, and the micro-rod is exposed and contacts the ground.

[0013] Preferably, the air bag includes an outer air bag and an inner air bag. The inner air bag is located in the middle of the outer air bag. The inner air bag and the outer air bag are interconnected. After the pressure in the outer air bag reaches a predetermined value, air is inflated into the inner air bag;

[0014] An outer protective layer is covered on the lower surface of the outer air bag, and the micro-grooves are located on the outer protective layer;

[0015] An inner protective layer is covered on the lower surface of the inner air bag. The micro-rod is located inside the inner air bag, and the installation crack is located on the inner protective layer.

[0016] Preferably, the other end of the micro-rod away from the protective layer is located inside the air bag. The micro-rod is arc-shaped, and the other end of the micro-rod is located on the side wall of the air bag close to the support foot, and the other end of the micro-rod just contacts the side wall of the air bag.

[0017] Preferably, an arc-shaped plate is installed at one end of the micro-rod located inside the air bag. The shape of the arc-shaped plate matches the shape of the side wall of the support foot, and the arc-shaped plate connects the micro-rods distributed along the same radial line.

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] As Figures 1 to 7 shown, a portable engineering surveying and mapping device of the present invention includes a mounting base 1, support legs 2 and a surveying instrument 11. The support legs 2 are hinged to the lower surface of the mounting base 1. A plurality of support legs 2 are provided on the mounting base 1, and the support legs 2 are evenly distributed around the center of the mounting base 1. At least three support legs 2 are provided. The surveying instrument 11 is installed on the upper surface of the mounting base 1, including:

[0032] Adjusting mechanism, the adjusting mechanism is installed at the lower end of the support leg 2, the adjusting mechanism contacts the ground after the support leg 2 stands on the ground, and the adjusting mechanism is used to improve the stability of the surveying and mapping device during use;

[0033] The adjusting mechanism includes an airbag, the airbag is installed at one end of the support leg 2 away from the mounting seat 1, the lower end of the support leg 2 contacts the ground prior to the lower surface of the airbag, the airbag is provided with an inflation port, a valve is provided on the inflation port of the airbag, and the airbag is connected to any one of an external manual balloon pump, a bicycle pump, and an electric air pump through a trachea for inflation;

[0034] When surveying / mapping is required, take the surveying and mapping device out of the storage box. Then, spread the support legs 2 under the mounting seat 1 apart from each other and stand the support legs 2 on the ground, so as to support the surveying instrument 11 by means of the support legs 2. At the same time, after placing the surveying instrument 11 on the ground and making the surveying instrument 11 stand up, the staff connects the balloon pump carried in the storage box to the inflation port of the airbag through a pipeline. Then, with the valve on the inflation port open, inflate the airbag, so that the airbag gradually expands and contacts the ground. At the same time, after the airbag contacts the ground, first close the valve on the inflation port, and then remove the balloon pump on the inflation port;

[0035] At the same time, when the airbag expands and contacts the ground, the expanded airbag fills the gaps and grooves on the ground, increasing the contact area between the end of the support leg 2, the airbag and the ground, thereby improving the stability of the surveying and mapping device placed on the ground, so as to avoid the ground at the surveying point being inclined or the ground being smooth, hard, resulting in the movement of the surveying instrument 11 during use, affecting the normal progress of surveying and mapping and increasing surveying errors;

[0036] At the same time, after the surveying and mapping is completed, the staff opens the valve on the inflation port, so that the gas in the airbag is discharged from the inflation port, and the airbag returns to its original state under its own elasticity. Then, the staff lifts the surveying and mapping device, closes the support legs 2 on the mounting seat 1 together and retracts them, and then puts the surveying instrument 11 back into the storage box for placement to protect the surveying instrument 11 and wait for the next use.

[0037] As an implementation manner of the present invention, a baffle 21 is installed at the lower end of the support leg 2, and the lower surface of the baffle 21 contacts the upper surface of the airbag;

[0038] The baffle 21 is connected to the support leg 2 by means of a thread;

[0039] When the surveying and mapping device is used up and retracted into the storage box for storage, the staff removes the baffle 21 on the support leg 2 and places it in the storage box to reduce the space occupied by the surveying and mapping device, facilitating the placement of the surveying and mapping device in the storage box for storage. At the same time, since the support leg 2 and the mounting base 1 are also detachably connected, when assembling the surveying and mapping device, the baffle 21 can be first sleeved onto the support leg 2 from one end of the support leg 2 close to the mounting base 1, and then the baffle 21 is moved to the end of the support leg 2 away from the mounting base 1 and fixed by threading. After the baffle 21 is installed, the support leg 2 is then connected to the mounting base 1;

[0040] At the same time, during the surveying process, when inflating the airbag, the airbag expands and contacts both the baffle 21 and the ground. Through the contact between the airbag and the baffle 21, the contact and the force-bearing area between the airbag and the support leg 2 are increased, ensuring the stability of the surveying and mapping device and the normal progress of the surveying. It avoids the ground at the surveying point being inclined, so that during the surveying, the airbag on the support leg 2 at the relatively lower position in the surveying and mapping device receives a greater force, or due to the influence of the staff's work, the airbag is subjected to a greater force, resulting in deformation at the contact between the airbag and the support leg 2 at the relatively lower position in the surveying and mapping device, that is, the airbag cannot support and bear the support leg 2, leading to the deviation / skew / movement of the surveying and mapping device, affecting the normal use of the surveying and mapping device and the accuracy of the surveying;

[0041] At the same time, when the ground conditions at the surveying point are different, the staff can adjust the relative distance between the baffle 21 and the airbag on the support leg 2 according to the actual situation to adapt to different ground states. It avoids that when the ground is relatively flat or the inclination is small, due to the relatively large distance between the baffle 21 and the airbag, in order to ensure the contact area and the support effect between the baffle 21 and the airbag, relatively more gas still needs to be filled into the airbag, resulting in an increase in the center of gravity of the surveying and mapping device, affecting the convenience of the staff's use and the stability of the surveying and mapping device during use.

[0042] As an implementation mode of the present invention, the airbags are interconnected through air pipes, and the air pipes used for connection are hidden inside the support leg 2, and the air pipes in different support legs 2 are connected to each other through detachable joints;

[0043] When inflating the airbag, the airbags on each support leg 2 are connected to each other through the air pipe, so that the staff only needs to inflate one of the airbags, and then each airbag can expand and contact the ground to complete the installation work of the surveying and mapping device;

[0044] Meanwhile, after inflating the airbag, the lower surface of the airbag contacts the ground, and the lower surface of the support leg 2 separates from the ground, so that the surveying and mapping device is exactly in a "floating" state under the action of the airbag. At the same time, since the airbags are interconnected through air pipes, according to the ideal gas state equation (p = NRT / V), it can be found that the pressures in the airbags will be equal. After different airbags are subjected to pressure, corresponding deformations will occur, so that the airbags installed on different support legs 2 are still under different forces and corresponding deformations occur, so that the pressures in the airbags are all equal. During this process, through the action of the airbags, the surveying and mapping device is leveled to a certain extent, which facilitates the use of the surveying and mapping device and reduces or eliminates the work intensity of subsequent staff for adjusting the angle of the surveying and mapping device.

[0045] As an embodiment of the present invention, a protective layer is covered on the lower surface of the airbag. The protective layer is made of silica gel material, and micro-grooves 311 are uniformly formed on the surface of the protective layer.

[0046] When conducting surveying and mapping, it is usually necessary to measure at multiple points. Therefore, the surveying and mapping device often needs to be moved during use. At the same time, the airbag on the surveying and mapping device contacts the ground. During the movement of the surveying and mapping device, it is easily affected by the ground, resulting in wear and damage to the airbag, affecting the service life of the airbag. By providing a protective layer on the lower surface of the airbag, the airbag is protected, the wear on the airbag is reduced, thereby improving the tolerance of the airbag to harsh ground conditions, extending the service life of the airbag, and preventing the airbag from bursting.

[0047] At the same time, the protective layer made of silica gel and the micro-grooves 311 formed on the protective layer can increase the friction between the airbag and the ground when the airbag contacts the ground, reduce the possibility of sliding during the use of the surveying and mapping device, and ensure the stability of the surveying and mapping device.

[0048] As an embodiment of the present invention, a micro-rod 5 is installed in the airbag. One end of the micro-rod 5 penetrates out of the airbag into the protective layer. An installation crack 411 is formed on the protective layer. The micro-rod 5 is located in the installation crack 411. After the airbag is inflated and expanded, the installation crack 411 unfolds, and the micro-rod 5 is exposed and contacts the ground.

[0049] During use, after the staff inflates the airbag, the protective layer made of silica gel will expand to a certain extent, causing the thickness of the protective layer to become thinner and the installation crack 411 to expand to both sides, thereby exposing the micro-rods 5 located in the installation crack 411 and contacting the ground. The fixing effect between the airbag and the ground is improved through the micro-needles, avoiding the sliding of the surveying device. At the same time, since the micro-rods 5 are located in the installation crack 411, when the airbag is not inflated, the ends of the micro-rods 5 outside the airbag will not contact the side wall of the airbag, thereby preventing the airbag from being stabbed by the ends of the micro-rods 5 when subjected to external forces and causing damage to the airbag.

[0050] As an embodiment of the present invention, the airbag includes an outer airbag 3 and an inner airbag 4. The inner airbag 4 is located in the middle of the outer airbag 3. The inner airbag 4 and the outer airbag 3 are interconnected. After the pressure in the outer airbag 3 reaches a predetermined value, the inner airbag 4 is inflated.

[0051] The lower surface of the outer airbag 3 is covered with an outer protective layer 31, and the micro-grooves 311 are located on the outer protective layer 31.

[0052] The lower surface of the inner airbag 4 is covered with an inner protective layer 41. The micro-rods 5 are located in the inner airbag 4, and the installation crack 411 is located on the inner protective layer 41.

[0053] During the inflation process of the airbag, the outer airbag 3 starts to inflate and expand first, thereby increasing the contact area of the surveying device with the ground and avoiding the movement of the surveying device. At the same time, since the airbags are interconnected, when the outer airbag 3 is inflated, the surveying device is also leveled to a certain extent. After that, the pressure in the outer airbag 3 reaches a predetermined value, and the gas in the outer airbag 3 enters the inner airbag 4, causing the inner airbag 4 to start inflating and expanding, thereby driving the micro-rods 5 in the inner airbag 4 to contact the ground, further fixing the surveying device, and preventing the surveying device from being affected by the actions of the operator during use and moving, which affects the surveying accuracy.

[0054] As an embodiment of the present invention, the other end of the micro-rod 5 away from the protective layer is located inside the airbag. The micro-rod 5 is arc-shaped. The other end of the micro-rod 5 is located on the side wall of the airbag near the support leg 2, and the other end of the micro-rod 5 just touches the side wall of the airbag.

[0055] When the micro rod 5 contacts the ground, there is a force between the micro rod 5 and the ground. Since the micro rod 5 is arc-shaped and the other end contacts the inner wall of the airbag near the support leg 2, the micro rod 5 has a certain supporting effect on the support leg 2, improving the fixing effect of the surveying and mapping device and the stability during use. When the airbag deforms due to the actions of the staff during use, the micro rod 5 provides support to the support leg 2, avoiding or reducing the deformation of the airbag, improving the stability of the surveying and mapping device, and preventing the accuracy of surveying and mapping from being affected.

[0056] As an embodiment of the present invention, an arc-shaped plate 51 is installed at one end of the micro rod 5 located inside the airbag. The shape of the arc-shaped plate 51 is matched with the shape of the side wall of the support leg 2, and the arc-shaped plate 51 is connected to the micro rods 5 distributed along the same radial line;

[0057] The arc-shaped plate 51 is used to combine the micro rods 5, preventing the micro rods 5 from being independent of each other and allowing the micro rods 5 to move freely inside the airbag, which may cause the end of the micro rod 5 located inside the airbag not to face the support leg 2 directly, thus affecting the supporting effect of the micro rod 5 on the support leg 2. At the same time, the arc-shaped plate 51 is used to contact the inner wall of the airbag, which can increase the contact area between the micro rod 5 and the inner wall of the airbag, preventing the micro rod 5 from damaging the inner wall of the airbag and affecting the normal use of the airbag. At the same time, through the mutual cooperation of the shapes of the arc-shaped plate 51 and the side wall of the support leg 2, it is ensured that the micro rod 5 moves smoothly during the inflation process of the airbag, preventing the micro rod 5 from shifting and no longer facing the support leg 2 directly during the inflation process of the airbag, resulting in the micro rod 5 losing its supporting effect on the support leg 2.
