Description

Technical Field

[0001] The invention belongs to the technical field of surveying and mapping auxiliary equipment, and in particular relates to a terrain surveying and mapping auxiliary device. Background Art

[0002] In surveying and mapping work, various surveying and mapping instruments are needed. When the surveying and mapping instruments are in use, auxiliary devices are usually needed to place the surveying and mapping instruments to assist the surveying and mapping instruments in surveying and mapping. When the existing auxiliary devices adjust the height of the surveying and mapping instruments, most of them use manual adjustment, which makes the entire height adjustment process more cumbersome.

[0003] The prior art CN220957581U discloses a terrain auxiliary surveying and mapping device, which starts the lifting motor to drive the rotating rod and the connecting rod to start rotating synchronously. The rotation of the connecting rod causes one end of the linkage rod to rotate at one end of the connecting rod, and the other end of the linkage rod rotates inside the linkage block, so that the placement plate and the lifting block slide up and down synchronously, and the lifting block slides on the surface of the supporting column, thereby realizing the adjustment of the height of the surveying and mapping instrument. Driven by the lifting motor, the height of the placement plate can be freely adjusted, so as to automatically adjust the height of the surveying and mapping instrument, thereby facilitating subsequent terrain surveying and mapping work, and no manual adjustment is required, thereby simplifying the height adjustment process of the auxiliary device.

[0004] However, the above-mentioned auxiliary surveying and mapping device cannot be applied to relatively uneven ground during use, so it is easy to be unstable during use, which will further affect the accuracy of measurement. Summary of the invention

[0005] The purpose of the present invention is to provide a terrain surveying and mapping auxiliary device, which aims to solve the technical problem that the existing auxiliary surveying and mapping devices cannot be used on relatively uneven ground, thus easily becoming unstable during use, which in turn affects the accuracy of measurement.

[0006] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0007] The present invention provides a topographic surveying and mapping auxiliary device, comprising a placement plate, and also comprising a clamping mechanism, a movable rod, a support seat, a support block, a support rod, a fixed block, a support disk and a chuck. The clamping mechanism is located on the placement plate and is used to clamp and fix a surveying and mapping instrument. The movable rod is arranged below the placement plate, and the support seat is slidably arranged outside the movable rod. There are three support blocks, which are evenly distributed below the support seat. The support rod is movably arranged in each support block, and the fixed block is movably arranged on a side of each support rod away from the support block. The support disk is arranged below each fixed block, and the chuck is arranged below each support disk.

[0008] Wherein, the clamping mechanism comprises a movable block and a clamping plate, the placement plate has a slide groove, the movable block is slidably arranged in the slide groove, and the clamping plate is arranged on the placement plate.

[0009] There are two movable blocks and two clamping plates, and the two movable blocks are respectively arranged on the left and right sides of the slide slot, and one clamping plate is arranged above each movable block.

[0010] Wherein, the clamping mechanism further includes a telescopic rod and a reset spring, the telescopic rod is arranged between the two movable blocks, and a reset spring is arranged between each movable block and the placement plate.

[0011] Wherein, a driving member is arranged between the placement plate and the support seat, and the driving member is located between the two movable rods and is used for driving the placement plate to move up and down above the support seat.

[0012] Wherein, the support rod includes a first rotating block, a connecting rod and a second rotating block, the first rotating block is movably connected to the support block and is located in the support block, the second rotating block is movably connected to the fixed block and is located in the fixed block, and the first rotating block and the second rotating block are connected by the connecting rod.

[0013] The support plate is evenly distributed with a plurality of threaded holes, and each of the threaded holes is provided with a removable fixing screw.

[0014] A terrain surveying and mapping auxiliary device of the present invention can improve the grip of the support plate by placing the support plate on the ground and inserting the clamp head under the ground, so as to facilitate fixing the support plate. Afterwards, by adjusting the rotation angles of the three support rods under the support seat in the support block and the fixing block respectively, and adjusting the distance between the support plate and the support seat, the height of the support plate and the spacing between adjacent support plates can be adjusted, so that the support plate can be placed on an uneven ground, and the surveying and mapping auxiliary device can be used on an uneven ground, which solves the technical problem that the existing auxiliary surveying and mapping devices cannot be used on relatively uneven ground, and are prone to instability during use, which will affect the accuracy of measurement.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] First embodiment

[0022] See also Figure 1 to Figure 3 Figure 1 is a schematic diagram of the overall structure of the terrain surveying and mapping auxiliary device of the first embodiment of the present invention, Figure 2 is a schematic diagram of the terrain surveying and mapping auxiliary device along the connecting rod 113 of the first embodiment of the present invention, Figure 3 1 is a schematic cross-sectional view of the terrain surveying and mapping auxiliary device according to the first embodiment of the present invention along the placement plate 101 .

[0023] The present invention provides a terrain surveying and mapping auxiliary device, including a placement plate 101, a clamping mechanism, a movable rod 102, a support seat 103, a support block 104, a support rod, a fixed block 105, a support disk 106 and a clamping head 107, the clamping mechanism includes a movable block 108, a clamping plate 109, a telescopic rod 110 and a reset spring 111, and the support rod includes a first rotating block 112, a connecting rod 113 and a second rotating block 114.

[0024] In this embodiment, by placing the support plate 106 on the ground and inserting the clamp 107 under the ground, the grip of the support plate 106 can be improved to facilitate fixing the support plate 106. Thereafter, by adjusting the rotation angles of the three support rods under the support seat 103 in the support block 104 and the fixing block 105 respectively, and adjusting the distance between the support plate 106 and the support seat 103, the height of the support plate 106 and the spacing between adjacent support plates 106 can be adjusted, so that the support plate 106 can be placed on an uneven ground, and the surveying and mapping auxiliary device can be used on an uneven ground, which solves the technical problem that the existing auxiliary surveying and mapping devices cannot be used on relatively uneven ground, and are prone to instability during use, which in turn affects the accuracy of measurement.

[0025] The clamping mechanism is located on the placement plate 101 and is used to clamp and fix the surveying and mapping instrument. The movable rod 102 is arranged below the placement plate 101. The support seat 103 is slidably arranged outside the movable rod 102. There are three support blocks 104, which are evenly distributed below the support seat 103. The support rod is movably arranged in each support block 104. The fixed block 105 is movably arranged on the side of each support rod away from the support block 104. The fixed block 105 is arranged below each fixed block 105. The support plate 106 is provided with the clamping head 107 under each of the support plates 106. The support seat 103 has a through hole. The movable rod 102 passes through the through hole of the support seat 103 and can slide up and down in the through hole of the support seat 103, thereby driving the placement plate 101 to move up and down above the support seat 103, and placing the support plate 106 on the ground. At this time, the clamping head 107 can be inserted under the ground, thereby improving the grip of the support plate 106, so as to fix the support plate 106.

[0026] Secondly, the placement plate 101 has a slide groove 115, the movable block 108 is slidably set in the slide groove 115, and the clamping plate 109 is set on the placement plate 101. Since the movable block 108 is slidably set in the slide groove 115, the movable block 108 can slide horizontally in the slide groove 115, thereby driving the clamping plate 109 to move horizontally above the placement plate 101.

[0027] Again, there are two movable blocks 108 and two clamping plates 109. The two movable blocks 108 are respectively arranged on the left and right sides of the slide groove 115. A clamping plate 109 is arranged above each movable block 108. The two movable blocks 108 can move relative to or away from each other in the slide groove 115, thereby driving the two clamping plates 109 to move relative to or away from each other above the placement plate 101, so that the two clamping plates 109 can jointly clamp and fix surveying and mapping instruments of different sizes.

[0028] At the same time, the telescopic rod 110 is arranged between the two movable blocks 108, and a reset spring 111 is arranged between each movable block 108 and the placement plate 101. The telescopic rod 110 can be retracted and retracted, so that the distance between the two movable blocks 108 can be adjusted, thereby adjusting the distance between the two clamping plates 109. At this time, since the reset spring 111 has a self-recovery effect, the reset spring 111 can drive the movable block 108 to move in the direction of returning to the original position, thereby driving the clamping plate 109 to move in the direction of returning to the original position, and then the two clamping plates 109 can jointly clamp and fix surveying and mapping instruments of different sizes.

[0029] In addition, a driving member 116 is arranged between the placement plate 101 and the support seat 103. The driving member 116 is located between the two movable rods 102 and is used to drive the placement plate 101 to move up and down above the support seat 103. A limiting plate 117 is arranged at the lower end of the movable rod 102. The limiting plate 117 is used to limit the extreme position of the up and down movement of the movable rod 102. The driving member 116 is a hydraulic telescopic rod 110. The output end of the hydraulic telescopic rod 110 is connected to the placement plate 101 and drives the placement plate 101 to move up and down above the support seat 103.

[0030] In addition, the first rotating block 112 is movably connected to the supporting block 104 and is located in the supporting block 104, the second rotating block 114 is movably connected to the fixed block 105 and is located in the fixed block 105, the first rotating block 112 and the second rotating block 114 are connected via the connecting rod 113, the supporting block 104 and the first rotating block 112 as well as the second rotating block 114 and the fixed block 105 are connected via a connecting pin 118, through the rotation of the first rotating block 112 in the supporting block 104 and the rotation of the second rotating block 114 in the fixed block 105, the rotation angles of the three supporting rods under the supporting seat 103 in the supporting block 104 and the fixed block 105 can be adjusted respectively, and at the same time, the distance between the supporting plate 106 and the supporting seat 103 can be adjusted, so that the height of the supporting plate 106 and the spacing between adjacent supporting plates 106 can be adjusted.

[0031] Finally, the support plate 106 is evenly distributed with a number of threaded holes 119, and each threaded hole 119 is provided with a removable fixing screw 120. By gradually screwing the fixing screw 120 into the threaded hole 119 and continuing to screw it into the ground, the grip of the support plate 106 can be further improved, and the stability of the support plate 106 fixed on the ground can be further improved.

[0032] When using a topographic surveying and mapping auxiliary device of the present embodiment, each of the support plates 106 is placed on the ground, and then the first rotating block 112 is rotated in the support block 104, and at the same time, the second rotating block 114 is rotated in the fixed block 105, so that the rotation angles of the three support rods under the support seat 103 in the support block 104 and the fixed block 105 can be adjusted respectively, and at the same time, the distance between the support plate 106 and the support seat 103 can be adjusted, so that the height of the support plate 106 and the spacing between adjacent support plates 106 can be adjusted, and by adjusting the height of the support plate 106 and the spacing between adjacent support plates 106, the support plate 106 can be placed on an uneven ground, so that the surveying and mapping auxiliary device can be used on an uneven ground.

[0033] When the support plate 106 is placed on an uneven ground, the clamp head 107 is inserted under the ground to improve the grip of the support plate 106, so as to fix the support plate 106. After that, the fixing screw 120 is gradually screwed into the threaded hole 119 and continues to be screwed under the ground, so as to further improve the grip of the support plate 106 and further improve the stability of the support plate 106 fixed on the ground.

[0034] After the support plate 106 is fixed on the uneven ground, the driving member 116 is started so that the power output from the output end of the driving member 116 drives the placement plate 101 to move up and down above the support seat 103, thereby driving the movable rod 102 to slide up and down in the through hole of the support seat 103, thereby driving the placement plate 101 to move up and down above the support seat 103, and then the height of the placement plate 101 can be adjusted so that workers of different heights can place the surveying and mapping instruments on the placement plate 101. At this time, the limit plate 117 can limit the extreme position of the up and down movement of the movable rod 102.

[0035] Afterwards, hold the clamping plate 109 and move the two clamping plates 109 away from each other, thereby driving the two movable blocks 108 to move away from each other in the slide groove 115. When the distance between the two clamping plates 109 gradually reaches the maximum, the distance between the two movable blocks 108 reaches the maximum. At this time, the telescopic rod 110 is stretched to the maximum position, and the return spring 111 is compressed to the limit position. Then place the surveying and mapping instrument between the two clamping plates 109 on the placement plate 101, loosen the two clamping plates 109, so that the compression force on the return spring 111 disappears. Since the return spring 111 has a self-recovery effect, the return spring 111 can drive the movable block 108 to move in the direction of returning to its original position, thereby driving the clamping plate 109 to move in the direction of returning to its original position, and then the two clamping plates 109 can jointly clamp and fix surveying and mapping instruments of different sizes to facilitate the subsequent use of the surveying and mapping instruments.

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
