[0051] See also Figures 1 to 9 As shown, this embodiment provides a guide structure for surveying and mapping equipment, including:

[0052] Guide frame 1;

[0053] A sliding plate 2, the sliding plate 2 being slidably disposed on the guide frame 1, the sliding plate 2 comprising a first sliding plate 21 and a second sliding plate 22;

[0054] A tripod 3, wherein the tripod 3 is disposed below the first sliding plate 21;

[0055] Rotating member 4, the first sliding plate 21 is connected to the tripod 3 via the rotating member 4;

[0056] The rotating member 4 includes a ball handle 41, a connecting rod 42, a guide ball 43 and a guide ball 44. The connecting rod 42 is vertically arranged on the top of the ball handle 41, the guide ball 43 is arranged in the ball handle 41, the bottom of the guide ball 43 protrudes from the bottom of the ball handle 41, and a connecting hole 45 is arranged at the bottom of the guide ball 43. Grooves 46 with a depth less than the diameter of the guide ball 44 are arranged on both sides of the guide ball 43. The two grooves 46 are arranged at different heights. The guide ball 44 is arranged in each of the grooves 46. A limiting track 47 is arranged on the inner wall of the ball handle 41. The limiting track 47 cooperates with the guide balls 44 protruding from the two grooves 46 to limit the connecting rod 42 to only tilt in one direction.

[0057] In this embodiment, the ball handle 41 is divided into two parts, an upper part and an lower part, which are connected by threads, so that the internal worn parts can be replaced. In other preferred embodiments, the ball handle 41 can also be divided into two parts, a left part and a right part, and can be connected more firmly by welding.

[0058] The top of the ball handle 41 is connected to the first sliding plate 21 through a connecting rod 42, and the guide ball 43 is connected to the tripod 3 through a rotating handle 48, wherein the rotating handle 48 is provided with the existing surveying and mapping instrument using the tripod 3, and different sizes of the rotating member 4 can be used according to different models of the tripod 3. The rotating handle 48 is a well-known component and will not be described in detail here;

[0059] Through the structural design of the guide frame 1, the sliding plate 2 and the rotating part 4 in conjunction with the tripod 3, the device can be adapted to the horizontal extension of most surveying and mapping instruments on the market. By fixing the surveying and mapping instrument on the second sliding plate 22 farther from the tripod 3, a heavy object can be hung on one end of the guide frame 1 closer to the tripod 3, so as to achieve long-distance extension while ensuring the stability of the device, so as to ensure the accuracy of the measurement result; the tripod 3 should be erected on the hard, non-settling ground closest to the surveying and mapping route. In order to avoid the problem that the mounted heavy object is suspended in the air and makes the guide frame 1 unstable during measurement, the mounted heavy object must be placed on the ground and connected to the guide frame 1 by an inelastic rope. The heavy object can be a stone made from local materials, or a bucket filled with water, etc.; the device can be used in the scene of soft ground in engineering operations, and the cost is lower than that of using drone operation equipment;

[0060] By setting the rotating member 4, through the cooperation of the ball handle 41, the connecting rod 42, the guide ball 43 and the guide ball 44, when the tripod 3 is connected to the first sliding plate 21 through the rotating member 4, the connecting rod 42 is kept vertical to ensure the horizontality of the guide frame 1, reducing the difficulty of subsequent horizontal adjustment of the surveying and mapping instrument, and the groove 46 and the protruding guide ball 44 are used to limit the connecting rod 42 to tilt only in one direction, which is used to lift the end of the guide frame 1 away from the tripod 3 after the tripod 3 is connected to the guide frame 1, so as to adjust the extension direction of the guide frame 1, and avoid the problem that the bottom of the first sliding plate 21 contacts the top of the tripod 3 due to possible deformation or wear of parts of the guide frame 1, making it impossible for the guide frame 1 to rotate;

[0061] Compared with connecting the tripod 3 and the first sliding plate 21 through a bearing, the structural design of the rotating member 4 can avoid the problem that the friction between the first sliding plate 21 and the top of the tripod 3 causes the guide frame 1 to rotate difficultly;

[0062] The second sliding plate 22 is provided with an adjustment slot 221, and the second sliding plate 22 is provided with a horizontal adjustment platform 222 above the adjustment slot 221. A surveying instrument (not shown in the figure) is provided on the horizontal adjustment platform 222, wherein the horizontal adjustment platform 222 adopts a three-way horizontal adjustment platform, and the surveying instrument can adopt a theodolite, a level, a total station, etc. The function of the adjustment slot 221 is to cooperate with the second sliding plate 21 in sliding on the guide frame 1 to achieve fine adjustment of the fixed point of the surveying instrument. The fixing form of the second sliding plate 21 on the horizontal adjustment platform 222 is the same as the fixing form of the guide ball 43 connected to the tripod 3 through the rotating handle 48, and will not be repeated here;

[0063] Telescopic rods 5 are provided at both ends of the guide frame 1, each of the telescopic rods 5 includes an outer rod 51, an inner rod 52 and a storage member 53, the inner rod 52 is telescopically arranged in the outer rod 51, a storage groove 54 is provided at the bottom end of the inner rod 52, the storage member 53 is arranged in the storage groove 54, the storage member 53 includes a rotating block 55 and a pressing plate 56, one end of the rotating block 55 is rotatably connected to the bottom end of the storage groove 54, and the other end of the rotating block 55 is rotatably connected to one end of the pressing plate 56;

[0064] The telescopic rod 5 is not in contact with the ground to bear pressure when in use, but is in a suspended state. A heavy object is pressed on the pressing plate 56, which can be used to replace hanging a heavy object on the guide frame 1. The installation of the device saves time and can convert the torque acting on the rotating member 4 into downward pressure to increase the stability of the device, reduce the wear of the rotating parts, and increase the service life.

[0065] Through the design of the storage groove 54 and the storage member 53, the storage member 53 can be retracted into the outer rod 51 together with the inner rod 52, saving space and avoiding damage to the outward-warping pressing piece 56 during transportation. In order to stably store the storage member 53 in the storage groove 54, a rubber sheet 57 is provided at the free end of the pressing piece 56. The present application does not specifically limit the size of the storage groove 54, which can be adjusted according to actual conditions.

[0066] The tops of the two telescopic rods 5 are rotatably connected to the guide frame 1, and the two telescopic rods 1 are staggered. The bottom of the sliding plate 2 is provided with two buckling members 23, and the free ends of the two telescopic rods 5 can be buckled in the buckling members 23 respectively by rotating; the buckling members 23 are used to store the telescopic rods 5. In this embodiment, the buckling members 23 are all arranged at the bottom of the first sliding plate 21. The buckling members 23 adopt lamp tube buckling springs, which can be purchased from the market and will not be repeated here.

[0067] The guide frame 1 is provided with support rods 11 at the corners, and the bottom ends of the support rods 11 protrude from the bottom of the guide frame 1; the support rods 11 are designed to be placed on a hard ground without hanging heavy objects or opening the telescopic rods 5. When the mapping scene has a hard ground at both ends of the guide frame 1, the erection time is saved. To ensure horizontality, the length of the support rods 11 protruding from the bottom of the guide frame 1 is adjustable, and the support rods 11 can be connected to the guide frame 1 using fasteners 12. The fasteners can be purchased from the market and will not be described in detail here.

[0068] The first sliding plate 21 and the second sliding plate 22 are provided with fixing members 6 at both sides of the bottom, each of the fixing members 6 includes two fixing plates 61, and the guide frame 1 is clamped by shrinking the bottom end distance of the two fixing plates 61, so as to fix the first sliding plate 21 and the second sliding plate 22; the fixing member 6 is used to fix the position of the first sliding plate 21 and the second sliding plate 22, and shrinking the bottom end distance of the two fixing plates 61 can be achieved by bolts and nuts, which will not be repeated here;

[0069] The tripod 3 includes three support rods 31 and a tray 32, and a limiting assembly 33 is provided between adjacent support rods 31; each limiting assembly 33 includes a limiting piece 34 and a limiting protrusion 35, and the limiting protrusion 35 is provided on one of the support rods 31, one end of the limiting piece 34 is rotatably connected to another support rod 31, and the other end of the limiting piece 34 is provided with a plurality of limiting grooves 36 matching the limiting protrusion 35;

[0070] At least one of the limiting grooves 36 on each limiting piece 34 is arranged at the top edge of each limiting piece 34; a rebound component 7 is arranged in at least one of the limiting grooves 36 on each limiting piece 34; each rebound component 7 includes a rebound member 71 and a fixing piece 72; each limiting piece 34 is provided with a rebound groove 73 on one side of the limiting groove 36 where the rebound component 7 is arranged; each fixing piece 72 is used to cover each rebound groove 73; each rebound member 71 is arranged in each rebound groove 73 and protrudes into each limiting groove 36; each rebound member 71 fixes the corresponding limiting protrusion 35 in the corresponding limiting groove 36 through elastic deformation;

[0071] In this embodiment, two limiting grooves 36 are provided on a single limiting piece 34, which are respectively provided at the bottom edge of the limiting piece 34 and the top edge of the limiting piece 34. The staggered arrangement can ensure that when the limiting protrusion 35 cooperates with the limiting groove 36, the limiting groove 36 provided on the same side edge will not damage the component strength of the limiting piece 34;

[0072] In this embodiment, the two limiting grooves 36 are both provided with a rebound component 7, and the function of the rebound component 7 is to ensure the stability of the cooperation between the limiting protrusion 35 and the limiting groove 36, and also to enable the limiting groove 36 to be set at the top edge of the limiting sheet 34. The rebound member 71 is formed by bending an elastic rod. In other preferred embodiments, the rebound member 71 can also be formed by bending an elastic sheet.

[0073] In other preferred embodiments, each of the limiting grooves 36 is disposed at the bottom edge of each of the limiting pieces 34 , which has a lower manufacturing cost.

[0075] When the device is used, the rotating member 4 is first threadedly connected to the first sliding plate 21 through the connecting rod 42, the position of the first sliding plate 21 on the guide frame 1 is adjusted by sliding and fixed, and then the rotating member 4 is connected to the tripod 3 by the rotating handle 48. When connecting, it should be noted that the tilting direction of the connecting rod 42 is opposite to the extending direction of the guide frame 1, and then the guide frame 1 is rotated to adjust the direction, and at the same time, the telescopic rod 5 close to the tripod 3 is opened, and the length of the telescopic rod 5 is adjusted so that the bottom of the telescopic rod 5 does not contact the ground, and at the same time, it is ensured that the pressing plate 56 can be pressed by a heavy object, the pressing plate 56 at the bottom of the telescopic rod 5 is opened, and a heavy object is pressed on the pressing plate 56, the position of the second sliding plate 22 on the guide frame 1 is adjusted by sliding and fixed, the surveying and mapping instrument is placed on the horizontal adjustment table 222, the position of the horizontal adjustment table 222 is adjusted and fixed, and the surveying and mapping instrument is horizontally adjusted through the horizontal adjustment table 222.
