Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping devices, and particularly to a surveying and mapping device for geological exploration. Background Art

[0002] Geological surveying and mapping is the general term for all surveying and mapping work involved in geological surveys and the compilation of their resulting maps, mainly including engineering surveying work such as geological point surveying, geological profile surveying, geophysical and geochemical prospecting surveying, exploration network layout surveying, exploration engineering positioning surveying, surface movement observation, etc., as well as the drawing and printing of relevant maps.

[0003] Most of the surveying and mapping devices in the existing general technology use the structure of a tripod to support and fix the device. When using the surveying and mapping device, it may involve adjusting the height of the theodolite. The support rods of the tripod are usually telescopic rods with adjustable lengths, and the staff needs to adjust them one by one to achieve the purpose of adjusting the height of the theodolite. The operation is relatively cumbersome. In addition, it is difficult to keep the theodolite level after adjusting the height, which has a certain impact on the surveying results. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a surveying and mapping device for geological exploration.

[0005] The above technical object of the present invention is achieved through the following technical solutions: A surveying and mapping device for geological exploration, including a base, a mounting table arranged above the base, and a theodolite body fixed on the top of the mounting table. A vertical rod is fixed to the bottom of the mounting table. A plurality of support rods evenly distributed about the axis of the vertical rod are hinged on the side wall of the vertical rod. A driving mechanism for simultaneously opening or closing the plurality of support rods is arranged on the vertical rod. A connecting rod is fixed to the bottom of the mounting table, and a connecting ball is fixed to the lower end of the connecting rod. A leveling mechanism for controlling the movement of the connecting ball to level the mounting table is arranged on the base.

[0006] By adopting the above technical solutions, when it is necessary to adjust the height of the theodolite body, the staff only needs to use the driving mechanism to simultaneously open or close the plurality of support rods, so that the height of the base at the upper end of the vertical rod and the mounting table on the base can be adjusted, so as to adjust the height of the theodolite body, changing the way in which the heights of the three support rods need to be adjusted one by one in the traditional design, improving the adjustment efficiency. After adjusting the height, the leveling mechanism can be used to control the movement of the connecting ball to quickly level the mounting table to ensure the surveying accuracy of the theodolite body.

[0007] Furthermore, a hemispherical housing is sleeved at the bottom of the connecting ball, a groove matching with the hemispherical housing is arranged at the top of the base, the diameter of the opening at the top of the groove is smaller than the outer diameter of the hemispherical housing, an arc-shaped groove body is arranged at the bottom of the hemispherical housing, and the center of the sphere of the hemispherical housing is located on the axis of the arc-shaped groove body; the leveling mechanism includes a first adjustment component, the first adjustment component includes a threaded rod fixed on the outer wall of the connecting ball and a fixing plate at the top of the hemispherical housing, there are two threaded rods which are respectively located on both sides of the connecting ball, the rotation directions of the two threaded rods are the same, the center of the sphere of the connecting ball is located on the axis of the threaded rod, the axis of the threaded rod is perpendicular to the axis of the arc-shaped groove body, there are also two fixing plates, the two fixing plates are respectively arranged near the two openings of the arc-shaped groove body, and the two threaded rods respectively penetrate through the two fixing plates and are in threaded connection, the leveling mechanism further includes a driving component arranged on the base and used for driving the threaded rod to rotate and a second adjustment component used for driving the hemispherical housing to swing around the axis of the arc-shaped groove body.

[0008] By adopting the above technical solution, when leveling the installation table and the surveying instrument body, the staff only needs to drive the threaded rod to rotate through the driving component. Since the threaded rod is in threaded connection with the fixing plate on the hemispherical housing, the connecting ball fixed to the threaded rod rotates (the connecting ball generates a relative displacement in the axial direction of the threaded rod during the rotation process), so that the installation table and the surveying instrument body can rotate around the axis of the threaded rod to perform the leveling work in one direction. The second adjustment component can drive the hemispherical housing to swing around the axis of the arc-shaped groove body, so that the fixing plate on the hemispherical housing and the threaded rod in threaded connection with the fixing plate swing synchronously, so as to realize the rotation of the connecting ball in the other direction, so as to realize the leveling work of the surveying instrument body in the other direction. After the leveling is completed, the adjustment is stopped, and the accuracy of the detection result of the surveying instrument body can be ensured.

[0009] Furthermore, a connecting groove is provided on the top of the base for the threaded rod to move and communicate with the groove, and a through hole is penetrated at the position corresponding to the base and the arc-shaped groove body, and the length direction of the through hole is parallel to the axial direction of the threaded rod, and the driving assembly includes an L-shaped plate body arranged on the base, a transmission rod penetrating and rotatably connected to the horizontal section of the L-shaped plate body, an upper driven gear fixedly sleeved on the transmission rod, a sleeve rotatably mounted on the side of the fixing plate away from the connecting ball, a first friction wheel fixed to an end of the sleeve away from the fixing plate, an active friction wheel fixed to the lower end of the transmission rod and pressed against the first friction wheel, an active rod rotatably mounted on the horizontal section of the L-shaped plate body, an upper motor fixed on the horizontal section of the L-shaped plate body and used to drive the active rod to rotate, and an upper active gear fixed to the lower end of the active rod and meshing with the upper driven gear, a transmission block is fixed on the threaded rod close to the first friction wheel, and the transmission block is located at a position away from one end of the connecting ball, and the inner wall of the sleeve is provided with a slot that slides with the transmission block.

[0010] By adopting the above technical solution, after leveling one direction of the surveying instrument body, the staff only needs to start the upper motor. After the upper motor works, it drives the active rod to rotate, so that the upper active gear fixed to the active rod, the upper driven gear meshing with the upper active gear, the transmission rod fixed to the upper driven gear, the active friction wheel fixed to the lower end of the transmission rod, the first friction wheel pressed against the active friction wheel, and the sleeve fixed to the first friction wheel all rotate. Since the slot in the sleeve and the transmission block on the threaded rod slide together, the threaded rod rotates synchronously with the sleeve, so that the connecting ball at the end of the threaded rod rotates synchronously, completing the leveling work of one direction of the surveying instrument body. The second adjustment component controls the hemispherical shell to swing around the axis of the arc-shaped groove body. Since the axis of the arc-shaped groove body is perpendicular to the axis of the threaded rod, the fixed plate rotates synchronously with the hemispherical shell, and the threaded rod connected to the fixed plate and the connecting ball fixed to the threaded rod all rotate, so that the leveling work of the connecting ball, the connecting rod, the mounting platform and the surveying instrument body in another direction can be carried out.

[0011] Furthermore, a communication groove is provided in the base and is communicated with both the side of the bottom of the connection groove away from the connection ball and the inner top wall of the through hole. The second adjustment assembly includes a vertical plate fixed to the top of the base, a guide rod penetrating through the vertical plate and slidably cooperating with the vertical plate, an electric push rod fixed to the side wall of the vertical plate away from the connection ball, an arc rack fixed in the arc-shaped groove body, a straight rack slidably cooperating with the through hole and meshing with the arc rack, an upper cross bar rotatably installed on the inner wall of the connection groove and perpendicular to the threaded rod, a second friction wheel fixedly sleeved on the upper cross bar and cooperating with the driving friction wheel, an upper synchronous wheel fixedly sleeved on the upper cross bar, a lower cross bar rotatably installed on the inner wall of the communication groove and parallel to the upper cross bar, a lower synchronous wheel fixedly sleeved on the lower cross bar, a synchronous belt meshing with both the lower synchronous wheel and the upper synchronous wheel, and a transmission gear fixedly sleeved on the lower cross bar and meshing with the straight rack. The push rod of the electric push rod penetrates through the vertical plate and slidably cooperates therewith. One end of the guide rod and the end of the push rod of the electric push rod are both fixed to the side wall of the vertical section of the L-shaped plate body away from the connection ball.

[0012] By adopting the above technical solution, after the leveling work of the surveying instrument body in one direction is completed, the staff needs to adjust the electric push rod to make the L-shaped plate body move towards the side away from the connection ball. Since the guide rod on the L-shaped plate body slidably cooperates with the vertical plate, when the driving friction wheel abuts against the second friction wheel, the upper motor works to make the driving friction wheel rotate, so that the second friction wheel in contact with the driving friction wheel, the upper cross bar fixed to the second friction wheel, and the upper synchronous wheel fixed to the upper cross bar all rotate. The lower synchronous wheel drives the lower synchronous wheel, the lower cross bar fixed to the lower synchronous wheel, the transmission gear fixed to the lower cross bar, the straight rack meshing with the transmission gear, and the arc rack fixed to the straight rack to rotate under the driving of the synchronous belt, so that the leveling work of the hemispherical shell, the fixing plate, the threaded rod, the connection ball, the connecting rod, the mounting table and the surveying instrument body in the other direction can be carried out.

[0013] Furthermore, a lower camera for monitoring the bottom of the mounting table is fixed to the top of the base, and a controller electrically connected to the lower camera is fixed to the top of the mounting table.

[0014] By adopting the above technical solution, the camera can monitor the position of the mounting table and transmit the information to the controller. The controller is preset with the picture code when the mounting table is in a horizontal state. When the mounting table is not horizontal, the controller can realize the leveling work of the surveying instrument body by controlling the operation of the upper motor and the electric push rod.

[0015] Furthermore, a spirit level and an upper camera for monitoring the spirit level are fixed to the top of the mounting table, and the upper camera is also electrically connected to the controller.

[0016] By adopting the above technical solution, the upper camera monitors the state of the spirit level in real time and transmits the monitoring result to the controller in the form of an electrical signal. The state information when the spirit level is in a horizontal state is preset in the controller. When the spirit level is not horizontal, the controller can achieve the leveling work of the total station body by controlling the operation of the upper motor and the electric push rod. The setting of the spirit level improves the accuracy of the leveling result.

[0017] Further, a rectangular mounting hole extending to a position near the lower end of the vertical rod is provided at the upper end of the vertical rod. A central screw extending to the upper end of the vertical rod is rotatably mounted on the inner bottom wall of the rectangular mounting hole. The driving mechanism includes a power component for driving the central screw to rotate and a connecting component for connecting the central screw and the support rod. The connecting component includes a movable block sleeved on the central screw and threadedly connected thereto and a traction rod hinged to the side wall of the movable block. There are four traction rods and four support rods. The four traction rods are evenly distributed around the circumference of the vertical rod. A vertical hole body for the traction rod to move and communicating with the rectangular mounting hole is provided on the side wall of the vertical rod, and the ends of the four traction rods away from the movable block are respectively hinged to the four support rods.

[0018] Further, the power component includes a lower motor fixed to the bottom of the base, a lower driving gear fixed to the output end of the lower motor, and a lower driven gear fixedly sleeved on the central screw and meshing with the lower driving gear. A connecting hole is provided on the vertical rod for the side of the lower driving gear close to the central screw to pass through and communicating with the rectangular mounting hole.

[0019] By adopting the above technical solution, after the lower motor works, it drives the lower driving gear to rotate, so that the lower driven gear meshing with the lower driving gear and the central screw fixed to the lower driving gear both rotate. Since the central screw is rotatably mounted on the inner bottom wall of the rectangular mounting hole, the central screw is threadedly connected to the movable block, and the movable block is slidably matched with the rectangular mounting hole, so that the movable block can be lifted and lowered. Since the traction rods are respectively hinged to the movable block and the support rods, the included angles between the four support rods relative to the vertical rod can be adjusted, and finally the height of the mounting table can be adjusted.

[0020] Further, a universal wheel with a brake is movably mounted at the lower end of the support rod.

[0021] By adopting the above technical solution, when the universal wheel is in the unlocked state, the staff can push the surveying device. When the universal wheel is in the locked state, the stability of the surveying device is ensured.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. In this application, when the height of the surveying instrument body needs to be adjusted, the staff only needs to use the driving mechanism to simultaneously open or retract multiple support rods, so that the height of the base at the upper end of the vertical rod and the mounting table on the base can be adjusted, so as to adjust the height of the surveying instrument body. This changes the way in which the heights of the three support rods need to be adjusted one by one in the traditional design, improves the adjustment efficiency. After adjusting the height, the leveling mechanism can control the movement of the connecting ball to quickly level the mounting table to ensure the surveying accuracy of the surveying instrument body;

[0024] 2. In this application, when leveling the mounting table and the surveying instrument body, the staff only needs to use the driving component to drive the threaded rod to rotate. Since the threaded rod is threadedly connected to the fixing plate on the hemispherical shell, the connecting ball fixed to the threaded rod rotates (the connecting ball generates a relative displacement in the axial direction of the threaded rod during rotation), so that the mounting table and the surveying instrument body can rotate around the axis of the threaded rod to perform leveling work in one direction. The second adjustment component can drive the hemispherical shell to swing around the axis of the arc-shaped groove body, so that the fixing plate on the hemispherical shell and the threaded rod threadedly connected to the fixing plate swing synchronously, so as to realize the rotation of the connecting ball in the other direction, so as to realize the leveling work of the surveying instrument body in the other direction. After the leveling is completed and the adjustment is stopped, the accuracy of the detection result of the surveying instrument body can be ensured. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a 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 of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0035] As Figure 1-8 shown, an embodiment of the present application discloses a surveying device for geological survey, including a base 1, a mounting table 2 disposed above the base 1, and a surveying instrument body 3 fixed to the top of the mounting table 2 (the surveying instrument body 3 is a surveying instrument dedicated to geological survey in the prior art, and its structure and principle of use both belong to the prior art). A vertical rod 4 is fixed to the bottom of the mounting table 2, and a plurality of support rods 41 evenly distributed about the axis of the vertical rod 4 are hinged to the side wall of the vertical rod 4. A driving mechanism 5 for simultaneously opening or closing the plurality of support rods 41 is provided on the vertical rod 4. A connecting rod 21 is fixed to the bottom of the mounting table 2, and a connecting ball 211 is fixed to the lower end of the connecting rod 21. A leveling mechanism 6 for controlling the movement of the connecting ball 211 to level the mounting table 2 is provided on the base 1.

[0036] When it is necessary to adjust the height of the surveying instrument body 3, the staff only need to use the driving mechanism 5 to simultaneously open or retract multiple support rods 41, so that the height of the base 1 at the upper end of the vertical rod 4 and the mounting table 2 on the base 1 can be adjusted, so as to adjust the height of the surveying instrument body 3. This changes the way in which the heights of the three support rods 41 need to be adjusted one by one in the traditional design, improving the adjustment efficiency. After adjusting the height, the leveling mechanism 6 can control the movement of the connecting ball 211 to quickly level the mounting table 2 to ensure the surveying accuracy of the surveying instrument body 3.

[0037] A hemispherical shell 7 is sleeved at the bottom of the connecting ball 211. A groove 11 matching with the hemispherical shell 7 is arranged at the top of the base 1. The diameter of the top opening of the groove 11 is smaller than the outer diameter of the hemispherical shell 7. An arc-shaped groove body 71 is arranged at the bottom of the hemispherical shell 7. The center of the sphere of the hemispherical shell 7 is located on the axis of the arc-shaped groove body 71; the leveling mechanism 6 includes a first adjustment component 61. The first adjustment component 61 includes a threaded rod 611 fixed to the outer wall of the connecting ball 211 and a fixing plate 612 at the top of the hemispherical shell 7. There are two threaded rods 611 which are respectively located on both sides of the connecting ball 211. The rotation directions of the two threaded rods 611 are the same. The center of the sphere of the connecting ball 211 is located on the axis of the threaded rod 611. The axis of the threaded rod 611 is perpendicular to the axis of the arc-shaped groove body 71. There are also two fixing plates 612. The two fixing plates 612 are respectively arranged near the two openings of the arc-shaped groove body 71, and the two threaded rods 611 respectively penetrate through the two fixing plates 612 and are in threaded connection. The leveling mechanism 6 further includes a driving component 62 arranged on the base 1 and used to drive the threaded rod 611 to rotate and a second adjustment component 63 used to drive the hemispherical shell 7 to swing around the axis of the arc-shaped groove body 71.

[0038] When leveling the mounting table 2 and the surveying instrument body 3, the staff only need to use the driving component 62 to drive the threaded rod 611 to rotate. Since the threaded rod 611 is in threaded connection with the fixing plate 612 on the hemispherical shell 7, the connecting ball 211 fixed to the threaded rod 611 rotates (the connecting ball 211 generates a relative displacement in the axial direction of the threaded rod 611 during rotation), so that the mounting table 2 and the surveying instrument body 3 can rotate around the axis of the threaded rod 611 to perform the leveling work in one direction. The second adjustment component 63 can drive the hemispherical shell 7 to swing around the axis of the arc-shaped groove body 71, so that the fixing plate 612 on the hemispherical shell 7 and the threaded rod 611 in threaded connection with the fixing plate 612 swing synchronously, so as to realize the rotation of the connecting ball 211 in the other direction and realize the leveling work of the surveying instrument body 3 in the other direction. After the leveling is completed, the adjustment is stopped, and the accuracy of the detection result of the surveying instrument body 3 can be ensured.

[0039] A connecting groove 12 for the threaded rod 611 to move and communicate with the groove 11 is provided at the top of the base 1. A through hole 13 is provided through the position of the base 1 corresponding to the arc-shaped groove body 71. The length direction of the through hole 13 is parallel to the axial direction of the threaded rod 611. The driving assembly 62 includes an L-shaped plate body 621 provided on the base 1, a transmission rod 622 penetrating through the horizontal section of the L-shaped plate body 621 and rotatably connected, an upper driven gear 623 fixedly sleeved on the transmission rod 622, a sleeve 624 rotatably installed on the side of the fixed plate 612 away from the connecting ball 211, a first friction wheel 625 fixed to the end of the sleeve 624 away from the fixed plate 612, a driving friction wheel 626 fixed to the lower end of the transmission rod 622 and abutted against the first friction wheel 625, a driving rod 627 rotatably installed on the horizontal section of the L-shaped plate body 621, an upper motor 628 fixed to the horizontal section of the L-shaped plate body 621 and used to drive the driving rod 627 to rotate, and an upper driving gear 629 fixed to the lower end of the driving rod 627 and meshed with the upper driven gear 623. A transmission block 6111 is fixed on the threaded rod 611 near the first friction wheel 625. The transmission block 6111 is located at the position away from the connecting ball 211. A straight groove 6241 for sliding cooperation with the transmission block 6111 is provided on the inner wall of the sleeve 624.

[0040] After leveling one direction of the surveying instrument body 3, the staff only needs to start the upper motor 628. After the upper motor 628 works, it drives the driving rod 627 to rotate, so that the upper driving gear 629 fixed to the driving rod 627, the upper driven gear 623 meshed with the upper driving gear 629, the transmission rod 622 fixed to the upper driven gear 623, the driving friction wheel 626 fixed to the lower end of the transmission rod 622, the first friction wheel 625 abutted against the driving friction wheel 626, and the sleeve 624 fixed to the first friction wheel 625 all rotate. Since the straight groove 6241 in the sleeve 624 is in sliding cooperation with the transmission block 6111 on the threaded rod 611, the threaded rod 611 rotates synchronously with the sleeve 624, so that the connecting ball 211 at the end of the threaded rod 611 rotates synchronously, completing the leveling work of one direction of the surveying instrument body 3. The second adjusting assembly 63 controls the hemispherical shell 7 to swing around the axis of the arc-shaped groove body 71. Since the axis of the arc-shaped groove body 71 is perpendicular to the axis of the threaded rod 611, the fixed plate 612 rotates synchronously with the hemispherical shell 7, and the threaded rod 611 connected to the fixed plate 612 and the connecting ball 211 fixed to the threaded rod 611 both rotate, so that the leveling work of the connecting ball 211, the connecting rod 21, the mounting table 2 and the surveying instrument body 3 in the other direction can be carried out.

[0041] A communication groove 14 is provided in the base 1 and communicates with both the bottom of the connection groove 12 on the side away from the connection ball 211 and the inner top wall of the through hole 13. The second adjustment assembly 63 includes a vertical plate 631 fixed to the top of the base 1, a guide rod 632 penetrating through the vertical plate 631 and slidingly engaged with the vertical plate 631, an electric push rod 633 fixed to the side wall of the vertical plate 631 away from the connection ball 211, an arc-shaped rack 634 fixed in the arc-shaped groove body 71, a straight rack 635 slidably engaged with the through hole 13 and meshed with the arc-shaped rack 634, an upper cross bar 636 rotatably installed on the inner wall of the connection groove 12 and perpendicular to the threaded rod 611, a second friction wheel 637 fixedly sleeved on the upper cross bar 636 and cooperating with the driving friction wheel 626, an upper synchronous wheel 638 fixedly sleeved on the upper cross bar 636, a lower cross bar 639 rotatably installed on the inner wall of the communication groove 14 and parallel to the upper cross bar 636, a lower synchronous wheel 640 fixedly sleeved on the lower cross bar 639, a synchronous belt 641 meshing with both the lower synchronous wheel 640 and the upper synchronous wheel 638, and a transmission gear 642 fixedly sleeved on the lower cross bar 639 and meshed with the straight rack 635. The push rod of the electric push rod 633 penetrates through the vertical plate 631 and is in sliding fit. One end of the guide rod 632 and the end of the push rod of the electric push rod 633 are both fixed to the side wall of the vertical section of the L-shaped plate body 621 away from the connection ball 211.

[0042] After the leveling work of the surveying instrument body 3 in one direction is completed, the staff needs to adjust the electric push rod 633 to make the L-shaped plate body 621 move towards the side away from the connection ball 211. Since the guide rod 632 on the L-shaped plate body 621 is slidably engaged with the vertical plate 631, when the driving friction wheel 626 abuts against the second friction wheel 637, the upper motor 628 works to make the driving friction wheel 626 rotate, thereby making the second friction wheel 637 in abutment with the driving friction wheel 626, the upper cross bar 636 fixed to the second friction wheel 637, and the upper synchronous wheel 638 fixed to the upper cross bar 636 all rotate. The lower synchronous wheel 640 drives the lower synchronous wheel 640, the lower cross bar 639 fixed to the lower synchronous wheel 640, the transmission gear 642 fixed to the lower cross bar 639, the straight rack 635 meshed with the transmission gear 642, and the arc-shaped rack 634 fixed to the straight rack 635 to rotate under the driving action of the synchronous belt 641, so that the leveling work of the hemispherical shell 7, the fixing plate 612, the threaded rod 611, the connection ball 211, the connecting rod 21, the mounting table 2, and the surveying instrument body 3 in the other direction can be carried out.

[0043] A lower camera 15 for monitoring the bottom of the mounting table 2 is fixedly installed on the top of the base 1, and a controller 22 electrically connected to the lower camera 15 is fixedly installed on the top of the mounting table 2. The camera can monitor the position of the mounting table 2 and transmit the information to the controller 22. The picture code of the mounting table 2 in a horizontal state is preset in the controller 22. When the mounting table 2 is not horizontal, the controller 22 can level the surveying instrument body 3 by controlling the operation of the upper motor 628 and the electric push rod 633.

[0044] A spirit level 23 and an upper camera 24 for monitoring the spirit level 23 are fixedly installed on the top of the mounting table 2, and the upper camera 24 is also electrically connected to the controller 22. The upper camera 24 monitors the state of the spirit level 23 in real time and transmits the monitoring result to the controller 22 in the form of an electrical signal. The state information of the spirit level 23 in a horizontal state is preset in the controller 22. When the spirit level 23 is not horizontal, the controller 22 can level the surveying instrument body 3 by controlling the operation of the upper motor 628 and the electric push rod 633. The setting of the spirit level 23 improves the accuracy of the leveling result.

[0045] A rectangular mounting hole 42 extending to a position near the lower end of the vertical rod 4 is provided at the upper end of the vertical rod 4. A central screw 8 extending to the upper end of the vertical rod 4 is rotatably installed on the inner bottom wall of the rectangular mounting hole 42. The driving mechanism 5 includes a power assembly 51 for driving the central screw 8 to rotate and a connecting assembly 52 for connecting the central screw 8 with the support rod 41. The connecting assembly 52 includes a movable block 521 sleeved on the central screw 8 and threadedly connected thereto and a traction rod 522 hinged to the side wall of the movable block 521. There are four traction rods 522 and four support rods 41. The four traction rods 522 are evenly distributed on the circumferential side of the vertical rod 4. A vertical hole body 43 for the traction rod 522 to move and communicating with the rectangular mounting hole 42 is provided on the side wall of the vertical rod 4, and one end of the four traction rods 522 away from the movable block 521 is respectively hinged to the four support rods 41.

[0046] The power assembly 51 includes a lower motor 511 fixed to the bottom of the base 1, a lower driving gear 512 fixed to the output end of the lower motor 511, and a lower driven gear 513 fixedly sleeved on the central screw 8 and meshing with the lower driving gear 512. A connecting hole 44 for the lower driving gear 512 to pass through the side close to the central screw 8 and communicating with the rectangular mounting hole 42 is provided on the vertical rod 4.

[0047] After the lower motor 511 works, it drives the lower driving gear 512 to rotate. Thus, the lower driven gear 512 meshing with the lower driving gear 512 and the central screw rod 8 fixed to the lower driving gear 512 both rotate. Since the central screw rod 8 is rotatably installed on the inner bottom wall of the rectangular installation hole 42, and the central screw rod 8 is threadedly connected to the movable block 521, and the movable block 521 is slidably engaged with the rectangular installation hole 42, the movable block 521 can be lifted and lowered. Since the traction rod 522 is hinged to the movable block 521 and the support rod 41 respectively, the included angles between the four support rods 41 relative to the vertical rod 4 can be adjusted, and finally the height of the installation table 2 can be adjusted.

[0048] The lower end of the support rod 41 is movably installed with a universal wheel 411 with a brake. When the universal wheel 411 is in the unlocked state, the staff can push the surveying and mapping device. When the universal wheel 411 is in the locked state, the stability of the surveying and mapping device is ensured.
