[0002] The statements here only provide the background art related to the present invention, and do not necessarily constitute the prior art.

[0003] A surveying and mapping layout device is a device for data acquisition, processing, output, etc. designed and manufactured for surveying and mapping operations. As a surveying and mapping technique, surveying and mapping layout is the three-dimensional positioning measurement of any spatial object. Its specific work is all reflected in the measurement of three quantities: distance, angle (direction), and elevation. No matter what method is used for layout, it is always necessary to use various types of instruments to calibrate the measurement results of these three quantities at the construction site.

[0004] Traditional layout instruments usually use a tripod as the support and fixation at the survey point. The bottom of the tripod's legs has a pointed end, which is suitable for fixation in the soil environment of uneven ground.

[0005] When the surveyed area has both uneven ground and soft soil ground, due to the fixed position of the pointed end at the bottom of the leg and the small contact area with the ground, the tripod is not firmly fixed on the soft soil ground, and it is easy to slip and cause the instrument to fall and be damaged, which is not convenient for continuous surveying operations on uneven ground and soft soil ground in the surveyed area.

[0044] The present invention will be further described in detail below in conjunction with the drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all of the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the invention without creative efforts shall fall within the scope of protection of the invention.

[0045] Please refer to Figures 1 to 11 .

[0046] An exploration point layout measurement device includes a tripod 1 and a layout instrument 2 installed on the tripod 1. Support devices are provided at the bottoms of the legs of the tripod 1. The layout instrument 2 is used for layout measurement operations at exploration points.

[0047] The support device includes a support column 4, and the top of the support column 4 is fixed to the bottom of the corresponding leg. A base plate 5 is fixed to the bottom of the support column 4. A ground insertion rod 6 coaxial with the support column 4 is accommodated inside the base plate 5, and the bottom of the ground insertion rod 6 has a tip. When measuring in an uneven soil environment, by inserting the tip at the bottom of the ground insertion rod 6 into the ground, the overall stability of the device on the land can be improved.

[0048] At least one support arm 21 parallel to the support column 4 is circumferentially arranged around the outside of the base plate 5, and a diagonal brace 22 coaxial with the support arm 21 is elastically accommodated inside the support arm 21. A swivel ring 8 is rotatably sleeved outside the support column 4.

[0049] The support device further includes a first driving component and a second driving component. The first driving component is arranged on the support column 4, and the second driving component is arranged on the base plate 5.

[0050] When the rotating ring 8 is rotated, the first driving assembly can drive the ground inserting rod 6 to protrude to the outside of the bottom of the bottom plate 5, and the second driving assembly can drive the bottom of the support arm 21 to deflect centrifugally, and axially extend the diagonal support rod 22 to the outside of the bottom of the support arm 21.

[0051] In specific implementation, when carrying out lofting measurement on a survey point on soft soil ground, directly unfold the tripod 1 and place it at the corresponding survey point, so that the bottom surface of the bottom plate 5 is in direct contact with the soft ground, ensuring the stability of the tripod 1 placed on the soft ground after unfolding, and then lofting measurement can be carried out.

[0052] When it is necessary to carry out lofting measurement on a survey point in an uneven soil environment, only need to rotate the rotating ring 8 at the bottom of each leg of the tripod 1, and the ground inserting rod 6 can be extended to the outside of the bottom of the bottom plate 5 under the cooperation of the first driving assembly, so that the tip of the bottom of the ground inserting rod 6 is inserted into the ground at that place, and under the cooperation of the second driving assembly, the bottom of the support arm 21 deflects centrifugally, and the diagonal support rod 22 axially extends to the outside of the bottom of the support arm 21, so that the diagonal support rod 22 can be obliquely inserted into the ground outside the bottom plate 5 to complete the fixation of the tripod 1 on the ground at that place.

[0053] The advantage of such a design is that by vertically inserting the ground inserting rod 6 into the ground of the uneven soil environment and cooperating with the diagonal support rod 22 to be obliquely inserted into the ground of the uneven soil environment, the device can be prevented from shaking during measurement, maintaining the overall stability of the device, and ensuring the accuracy of the device in carrying out line setting measurement at the survey point.

[0054] It is worth mentioning that the ground inserting rod 6 of the present application is in a stored state inside the bottom plate 5 when not in use, avoiding the situation that the tip of the ground inserting rod 6 accidentally injures external users or the tip is accidentally injured and damaged. At the same time, the diagonal support rod 22 is in a stored state inside the support arm 21 (parallel to the support column 4) when not in use, avoiding the situation that the diagonal support rod 22 accidentally injures external users or the rod end is accidentally injured and damaged.

[0055] It should be noted that a connecting plate 3 is fixed to the top of the support column 4 of the present application, and the top of the connecting plate 3 is installed at the bottom of the corresponding leg of the tripod 1 through an adjusting bolt, so as to adjust the rotation angle between the support device and the bottom of the leg of the tripod 1, so that the tripod 1 can not only be adaptively installed on a horizontal ground, but also be adaptively installed on an inclined slope.

[0056] In an embodiment, the first driving assembly includes a cylinder 11 that is axially movable and sleeved outside the support column 4, the top of the cylinder 11 is inserted inside the rotating ring 8, a second groove 12 in a spiral shape is axially formed on the inner circumferential wall of the rotating ring 8, and a second convex block 13 that is slidably engaged with the second groove 12 is arranged on the outer wall of the cylinder 11.

[0057] A first connecting rod 16 parallel to the axis of the support column 4 is inserted at the top of the bottom plate 5. The top of the first connecting rod 16 is fixedly connected to the outer wall of the bottom of the cylinder 11, and the bottom of the first connecting rod 16 extends into the bottom plate 5 and is fixed to the top wall of the ground insertion rod 6.

[0058] In specific implementation, the rotation of the swivel ring 8 can cause the groove wall of the second groove 12 with an axial spiral shape to continuously frictionally squeeze the second convex block 13, so that the cylinder 11, under the limiting action of the third convex block 14 and the third groove 15, realizes the axial downward movement of the cylinder 11 relative to the support column 4, and then drives the ground insertion rod 6 to extend out of the bottom of the bottom plate 5 through the first connecting rod 16.

[0059] In this way, only by simply rotating the swivel ring 8, the ground insertion rod 6 can be quickly extended from the bottom plate 5, so as to facilitate the insertion operation of the ground insertion rod 6 on the uneven soil ground.

[0060] Preferably, a third groove 15 is axially formed on the outer wall of the support column 4, and a third convex block 14 that is slidably clamped and matched with the third groove 15 is arranged on the inner side wall of the cylinder 11, so that the cylinder 11 can move only in the axial direction of the support column 4.

[0061] In one embodiment, a receiving groove 7 for receiving the ground insertion rod 6 is formed at the bottom of the bottom plate 5. Two baffles 20 are oppositely arranged at the bottom of the bottom plate 5 with respect to the notch of the receiving groove 7. When the two baffles 20 are butted, a sealing plate (not marked) for closing the bottom notch of the receiving groove 7 is formed.

[0062] The advantage of such a design is that when the ground insertion rod 6 is completely received in the receiving groove 7, the notch of the receiving groove 7 can be completely closed between the two baffles 20, so that the inside of the receiving groove 7 is in a closed state, avoiding damage to the ground insertion rod 6 by pollutants in the external environment, and can play a good role in receiving the ground insertion rod 6 when it does not need to protrude from the bottom of the bottom plate 5, avoiding accidental injury to external users by the tip of the ground insertion rod 6 or being accidentally damaged.

[0063] Furthermore, a plate receiving groove (not marked) for receiving the baffle 20 is formed at the bottom of the bottom plate 5. When the ground insertion rod 6 protrudes to the outside of the bottom of the bottom plate 5, the two baffles 20 are in a separated state, and at this time, the plate body of the baffle 20 is received in the corresponding plate receiving groove to provide a clearance space for the extension of the ground insertion rod 6.

[0064] Even further, both the separated sides of the two baffles 20 are connected to the corresponding plate wall of the bottom plate 5 through a telescopic rod 34, that is, the two ends of the telescopic rod 34 are respectively butted against the groove wall of the plate receiving groove and the plate wall of the baffle 20. A first spring (not marked) is sleeved outside the telescopic rod 34, and the two ends of the first spring are respectively connected to the corresponding plate surface of the baffle 20 and the corresponding plate wall of the bottom plate 5, that is, the two ends of the first spring are respectively butted against the groove wall of the plate receiving groove and the plate wall of the baffle 20.

[0065] Thus, when the two baffles 20 are butted against each other, both the first spring and the telescopic rod 34 are in a non-deformed state. When the two baffles 20 are separated, both the first spring and the telescopic rod 34 are in a compressed state, so that when the ground plug rod 6 is retracted into the accommodation groove 7, the elastic force of the first spring can, under the guidance of the telescopic rod 34, make the two baffles 20 return to the butted state to form a sealing plate to close the bottom notch of the accommodation groove 7, thereby completing the accommodation and protection of the ground plug rod 6.

[0066] In one embodiment, the tops of the adjacent sides of the two baffles 20 are provided with inclined surfaces 33 which are in sliding contact fit with the bottom of the ground plug rod 6. In this way, when the tip at the bottom of the ground plug rod 6 moves downward, it can press against the inclined surface 33, and the automatic separation between the two baffles 20 can be realized.

[0067] In one embodiment, the second driving assembly includes at least one limiting rod 25 circumferentially arranged around the pillar 4. The first connecting rod 16 is parallel to the pillar 4. At least one first limiting groove 23 extending radially is circumferentially formed in the top of the bottom plate 5. At least one second limiting groove 24 extending in a centripetal arc shape is circumferentially formed in the bottom annular surface of the rotating ring 8.

[0068] The bottom of the limiting rod 25 is slidably clamped in the corresponding first limiting groove 23, and the top is slidably clamped in the corresponding second limiting groove 24. A second connecting rod 26 parallel to the extending direction of the groove body of the corresponding first limiting groove 23 is arranged on the outer wall of the limiting rod 25 away from the pillar 4.

[0069] At least one mounting bracket 27 is circumferentially arranged on the top of the bottom plate 5. The mounting bracket 27 has an inverted L-shaped structure. The top of the support arm 21 is rotatably arranged on the frame body of the corresponding mounting bracket 27. The centrifugal end of the second connecting rod 26 is rotatably connected to the outer wall of the corresponding support arm 21. The second connecting rod 26 and the corresponding support arm 21 are connected through a pin shaft and a pin hole.

[0070] A transmission assembly is arranged on the mounting bracket 27. When the centrifugal movement of the second connecting rod 26 drives the support arm 21 to deflect around the connection point between the support arm 21 and the corresponding mounting bracket 27, the transmission assembly can drive the diagonal strut 22 to axially extend to the outside of the bottom of the support arm 21.

[0071] In specific implementation, the rotation of the swivel ring 8 can also cause the wall of the second limiting groove 24 that bends and extends centripetally to continuously frictionally squeeze the top of the limiting rod 25. At this time, the bottom of the limiting rod 25 will be limited by the wall of the first limiting groove 23 that extends radially, forcing the limiting rod 25 to drive the second connecting rod 26 to move centrifugally along the extending direction of the corresponding first limiting groove 23 body, so that the second connecting rod 26 drives the support arm 21 to deflect centrifugally outward around the rotation connection of the support arm 21 and the mounting frame 27. In this process, with the cooperation of the transmission component, the diagonal strut 22 axially extends to the outside of the bottom of the support arm 21, so that the diagonal strut 22 can be obliquely inserted into the ground outside the bottom plate 5, further completing the fixation of the tripod 1 on the ground at this place.

[0072] The advantage of such a design is that by obliquely inserting the diagonal strut 22 into the ground in an uneven soil environment and cooperating with the ground insertion rod 6 inserted perpendicular to the ground, the shaking of the device during measurement can be further avoided, the overall stability of the device can be maintained, and the accuracy of the device in setting out and measuring at the survey point can be ensured.

[0073] In one embodiment, the transmission component includes a fixed shaft 28 fixed on the mounting frame 27. A fixed gear 29 is sleeved and fixed on the fixed shaft 28. A fixing plate 30 is provided at the top of the support arm 21. The fixing plate 30 is rotatably sleeved outside the fixed shaft 28. A moving gear 31 that can move along the outer circumference of the fixed gear 29 and engage and rotate is inserted on the fixing plate 30. A wire wheel 32 is coaxially fixed on the tooth shaft of the moving gear 31. A tensioned pull rope (not labeled) is wound around the wire wheel 32. The free end of the pull rope extends into the corresponding support arm 21 and is fixed to the top of the corresponding diagonal strut 22. The top of the diagonal strut 22 is elastically connected to the inner side wall of the support arm 21.

[0074] In this embodiment, a second spring (not labeled) is provided between the top of the diagonal strut 22 and the inner side wall of the support arm 21. When the diagonal strut 22 is completely received inside the support arm 21, the second spring is in a compressed deformation state. When the diagonal strut 22 moves outward from the bottom of the support arm 21, the degree of the compressed deformation state of the second spring gradually decreases.

[0075] In specific implementation, when the centrifugal end of the second connecting rod 26 drives the support arm 21 to deflect centrifugally, the support arm 21 deflects relative to the fixed shaft 28 through the fixing plate 30, which will cause the moving gear 31 on the fixing plate 30 to move along the outer peripheral side of the fixed gear 29 and engage and rotate. The moving gear 31 drives the wire wheel 32 to rotate to pay out the pull rope, and then the diagonal strut 22 will axially extend to the outside of the bottom of the support arm 21 under the action of the elastic force release of the second spring and be obliquely inserted into the ground.

[0076] The advantage of such a design is that, on the basis of vertically inserting the ground plug rod 6 downward into the ground of an uneven soil environment, and then cooperating with the diagonal strut 22 to insert downward into the ground of the uneven soil environment, the shaking of the device during measurement can be avoided to the greatest extent, the overall stability of the device can be maintained, and the accuracy of the device in laying out and measuring at the survey point can be ensured.

[0077] In one embodiment, a first convex block 9 is fixed inside the swivel ring 8, and a first groove 10 that is slidably clamped and matched with the first convex block 9 is circumferentially formed on the outer peripheral side of the support column 4, so that the swivel ring 8 can rotate relative to the support column 4.

[0078] In one embodiment, a fixed ring 17 located above the swivel ring 8 is sleeved and fixed on the outer side of the support column 4. A pin 18 is axially inserted on the ring surface of the fixed ring 17, and at least one jack 19 that is clamped and matched with the pin 18 is circumferentially formed on the top of the swivel ring 8.

[0079] The purpose of such a design is that, through the cooperation of the pin 18 and the jack 19, the positions of the swivel ring 8 before and after rotation can be correspondingly locked, ensuring the stability of the support device in each state.

[0080] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0081] It should be noted that if there are directional indications (such as up and down) in the embodiments of the invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0082] In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution where A and B are satisfied simultaneously. In addition, if there are descriptions such as "first" and "second" in the embodiments of the invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.
