Description

Technical Field

[0001] The utility model relates to the technical field of surveying instruments, in particular to a surveying instrument positioning device for engineering surveying and mapping. Background Art

[0002] A surveying instrument is a specialized piece of measurement equipment used for precise measurements of ground or spatial locations in activities such as engineering construction and geological exploration. As a crucial tool for data collection, processing, and output, the accuracy and stability of a surveying instrument's positioning directly impact the precision of surveying and mapping results.

[0003] Existing surveying instruments are fixed to their outdoor measurement locations using a positioning device. Once installed, these devices are rarely removed. When in use, the positioning device is simply moved. When not in use, the positioning device and the instrument are simply stored in a warehouse or studio without dust protection measures. If the instrument is left unused for extended periods, dust accumulates both inside and outside. Since the instrument is a precision instrument, dust can affect its optical components and internal circuit boards, hindering its proper operation. Furthermore, the irregular outer surface of the instrument makes dust difficult to clean. Utility Model Content

[0004] In order to solve the technical problems existing in the above background technology, the utility model provides a surveying instrument positioning device for engineering surveying and mapping.

[0005] The technical solution of this utility model is as follows:

[0006] A surveying instrument positioning device for engineering surveying and mapping comprises a base and a lifting mechanism provided thereon, the lifting mechanism comprising a lifting and lowering bearing seat, the bearing seat being provided with a rotating mechanism, the rotating mechanism comprising a turntable having a vertical axis and being rotatable about the axis;

[0007] A protective box for placing the surveying instrument body is provided on the turntable. The protective box includes a box body and a box cover that can be opened and closed. The box cover is adapted to the box body. The surveying instrument body is arranged on the upper part of the box body, and the height of the surveying instrument body in the vertical direction inside the box body is adjustable.

[0008] The lifting mechanism can drive the surveying instrument body on the bearing seat to move up and down, and the rotating mechanism can drive the surveying instrument body to rotate a certain angle in the horizontal plane, thereby increasing the surveying range of the surveying instrument body without the need to rotate or move the positioning device as a whole. By arranging an openable and closable box cover on the surveying instrument body, the surveying instrument body when not in use can be sealed and protected, reducing the erosion of the surveying instrument body by external dust and ensuring the cleanliness of the surveying instrument body.

[0009] To ensure that the surveying instrument body can be used for surveying and mapping directly after the box cover is opened without being taken out of the box, a placement plate arranged in the horizontal direction is provided in the box. The placement plate is detachably connected to the box and the height is adjustable.

[0010] Regarding the specific structure of the box lid that can be opened and closed, the box body has a front side and a rear side, the detection end of the surveying instrument body is arranged close to the front side, the rear side is hinged to the box lid, and at least one automatic opening and closing part is provided on the left and / or right side of the box body, and the automatic opening and closing part connects the box body and the box lid.

[0011] The structure of the automatic opening and closing component is that the automatic opening and closing component is an electric push rod or a hydraulic cylinder, and the automatic opening and closing component has an output end and a shell, the output end is hinged to the box cover, and one end of the shell is hinged to the rear side of the box body.

[0012] The structure of the lifting mechanism is as follows: the lifting mechanism includes a lifting body, a ball screw and a first motor connected thereto are provided in the lifting body, the ball screw includes a matching screw rod and a nut frame, and the bearing seat is connected to the nut frame.

[0013] The specific structure of the rotating mechanism is that the rotating mechanism includes a second motor arranged on the supporting seat. The output end of the second motor is arranged vertically and is connected to the center transmission of the turntable through a belt transmission mechanism. The turntable drives the protective box and the surveying instrument body thereon to rotate a certain angle.

[0014] In order to facilitate the automatic opening of the cover of the protective box when the height position of the surveying instrument is adjusted, a control module is provided inside the base, and the first motor and the automatic opening and closing component are electrically connected to the control module respectively. When the first motor is driven to operate and the height position of the surveying instrument body is adjusted, the cover can be opened synchronously, which facilitates the quick use of the surveying instrument body.

[0015] By adjusting the height of the placement plate, the height of the surveying instrument body on it in the box can be adjusted so that the box will not block the normal use of the detection end of the surveying instrument body. The specific structure of the above-mentioned placement plate that can adjust the height in the box is that the placement plate is provided with L-shaped adjustment plates near the front and rear sides of the box. The L-shaped adjustment plate includes a short plate and a long plate. The short plate is plugged into the placement plate, and the long plate is provided with a clamping block on the side close to the inner wall of the box. The inner wall of the box is provided with multiple clamping grooves adapted to the clamping blocks along the vertical direction.

[0016] To facilitate adjustment of the placement plate, a gap is left between the front and rear sides of the box and the placement plate. The length of the gap is greater than the length of the clamping block. By moving the short plate toward one side of the placement plate, the clamping block is disengaged from the clamping groove, and the height position of both sides of the placement plate can be adjusted.

[0017] The beneficial effects of the present invention are:

When the cover is closed on the top of the protective box, the cover and the protective box can provide a sealed protection for the surveying instrument body when not in use, thereby reducing the erosion of the surveying instrument body by external dust, thereby ensuring the cleanliness of the surveying instrument body;

[0019] (2) The belt transmission mechanism is driven by a second motor to rotate, so that the belt transmission mechanism drives the turntable to rotate via the vertical shaft, so that the turntable drives the surveying instrument body inside the protective box to rotate synchronously, thereby slightly adjusting the angle of the surveying instrument body horizontally without moving the positioning device as a whole, thereby improving the surveying range of the surveying instrument body when the positioning device is used;

[0020] (3) The first motor drives the screw rod to rotate, so that the nut rack is located on the outer wall of the screw rod to slide, and the nut rack drives the slide seat to slide on the outer wall of the limit rail. The nut rack can drive the bearing seat to rise and fall, so as to adjust the height of the surveying instrument body as needed according to the use environment, thereby improving the convenience of using the positioning device;

[0021] (4) The placement plate is provided with L-shaped adjustment plates near the front and rear sides of the box. By adjusting the height of the placement plate, the height of the surveyor body on the box can be adjusted so that the box does not block the normal use of the detection end of the surveyor body.

[0022] (5) When the first motor is driven to operate and the height position of the surveying instrument body is adjusted, the control module controls the automatic opening and closing member to extend, and the box cover can be opened synchronously, so as to facilitate the quick use of the surveying instrument body.

The lifting mechanism includes a hollow lifting body 4, which is vertically arranged, and a strip limit groove 6 is provided on one side of the lifting body 4. A first motor 5 is provided on the upper end thereof. A ball screw 16 located inside the lifting body 4 is connected below the first motor 5. The screw rod 16 of the ball screw 16 is vertically arranged, and a nut rack 7 adapted to it is connected to the screw. The nut rack 7 can move along the length direction of the screw rod 16. A vertical limit rail 17 is also provided inside the lifting body 4. One side of the nut rack 7 is slidably connected to the limit rail 17 through a slide 18, and the sliding direction is vertical. The limit rail 17 can limit the nut rack 7. The other side of the nut rack 7 passes through the strip limit groove 6 and is connected to the bearing seat 8 located outside the lifting body 4. By driving the first motor 5, the screw rod 16 is driven to rotate, so that the nut rack 7 drives the bearing seat 8 to move up and down, thereby realizing the lifting and lowering of the surveying instrument body 14 on the bearing seat 8.

[0032] See also Figure 3 As shown, a rotating mechanism is provided on the supporting base 8, which includes a transmission box 9, a second motor 10 arranged in the transmission box 9, and a turntable 11 with a vertical axis and capable of rotating around its axis. The output end of the second motor 10 is arranged vertically and is connected to the center of the turntable 11 through a belt transmission mechanism 19. A vertical shaft is provided at the center of the turntable 11, and the vertical shaft is connected to the belt transmission mechanism 19. The belt transmission mechanism 19 is a prior art. The turntable 11 drives the protective box and the surveying instrument body 14 thereon to rotate a certain angle, so that the angle of the surveying instrument body 14 can be slightly adjusted horizontally without moving the positioning device as a whole, thereby improving the surveying range of the surveying instrument body 14 when the positioning device is used.

[0033] See also Figure 4As shown, a protective box for the surveyor 14 is located on the turntable 11. The protective box comprises a housing 12 and a retractable lid 15 that fits snugly within the housing 12. The surveyor 14 is positioned atop the housing 12, and its vertical height within the housing 12 is adjustable. To ensure that the surveyor 14 can be used directly for surveying after the lid 15 is opened without having to be removed from the housing 12, a horizontal mounting plate 13 is provided within the housing 12, removably connected to the housing 12.

[0034] See also Figure 5 As shown, by adjusting the height of the placement plate 13, the height of the surveying instrument body 14 on it in the box 12 is adjusted, so that the box 12 does not block the normal use of the detection end of the surveying instrument body 14. The specific structure of the placement plate 13 that can adjust the height in the box 12 is that the placement plate 13 is provided with an L-shaped adjustment plate 22 near the front and rear sides of the box 12. The L-shaped adjustment plate 22 includes a short plate 221 and a long plate 222 arranged vertically. The long plate 222 is vertically arranged on the inner wall of the box 12 On one side, the mounting plate 13 has symmetrically defined long slots 131 on both sides. These slots 131 mate with the short plates 221, which are inserted into the slots. The length of the long slots 131 is greater than that of the short plates 221. A return spring 20 is located within the slots 131. The return spring 20 is a compression spring, with its ends connecting the short plates 221 and the long slots 131, respectively. The length of the return spring 20 aligns with that of the short plates 221, thereby resetting the short plates 221. A snap-fit block 23 is provided on the side of the long plate 222 near the inner wall of the housing 12. The inner wall of the housing 12 is vertically defined with multiple snap-fit slots 121 that mate with the snap-fit blocks 23.

[0035] When the placement plate 13 needs to be adjusted, the short plate 221 is moved inward at the same time and inserted into the long groove 131, so that the clamping block 23 is disengaged from the clamping groove 121. At the same time, the placement plate 13 can be moved up and down by pulling the long plate 222, and the placement plate 13 is adjusted to a suitable position so that the detection end of the surveying instrument body 14 thereon is not blocked by the box body 12 and can be used normally; when the surveying instrument body 14 is not in use, the L-shaped adjustment plate 22 can be adjusted to move the placement plate 13 down to the lowest position, so that the surveying instrument body 14 is located inside the box body 12 to play a protective role.

[0036] To facilitate adjustment of the placement plate 13, a gap is left between the front and rear sides of the box body 12 and the placement plate 13. The length of the gap is greater than the length of the clamping block 23. By moving the short plate 221 toward the side of the placement plate 13, the clamping block 23 is disengaged from the clamping groove 121, and the height position of both sides of the placement plate 13 can be adjusted.

[0037] The above-mentioned lifting mechanism can drive the surveying instrument body 14 on the supporting seat 8 to move up and down, and the rotating mechanism can drive the surveying instrument body 14 to rotate a certain angle in the horizontal plane, thereby increasing the surveying range of the surveying instrument body 14 without the need to rotate or move the positioning device as a whole. By providing an openable and closable box cover 15 on the surveying instrument body 14, the surveying instrument body 14 in an unused state can be sealed and protected, reducing the erosion of the surveying instrument body 14 by external dust, thereby ensuring the cleanliness of the surveying instrument body 14.

[0038] See also Figure 1 and Figure 4 As shown, regarding the specific structure of the box cover 15 that can open and close, the box body 12 has a front side and a rear side. The detection end of the surveying instrument body 14 is located near the front side, and the rear side is hinged to the box cover 15. At least one automatic opening and closing member 21 is provided on the left and / or right side of the box body 12, and the automatic opening and closing member 21 connects the box body 12 and the box cover 15. The structure of the automatic opening and closing member 21 is that the automatic opening and closing member 21 is an electric push rod, and the automatic opening and closing member 21 has an output end and a housing. The output end is hinged to the box cover 15, and one end of the housing is hinged to the rear side of the box body 12.

[0039] In order to facilitate the automatic opening of the cover 15 of the protective box when the height position of the surveyor is adjusted, a control module is provided inside the base 1, and the first motor 5 and the automatic opening and closing member 21 are electrically connected to the control module respectively. When the first motor 5 is driven to operate and the height position of the surveyor body 14 is adjusted, the cover 15 can be opened synchronously, which facilitates the quick use of the surveyor body 14.
