Description

Technical Field

[0001] This invention relates to the field of surveying equipment technology, and in particular to a surveying equipment for engineering surveying. Background Technology

[0002] During the planning, design, construction, and operation management phases of engineering construction, various instruments such as theodolites, levels, total stations, laser measuring instruments, and plane tables are required to carry out various surveying and mapping tasks, including orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry.

[0003] Existing engineering surveying instruments require the use of corresponding tripods during operation. This means that in addition to moving the surveying instruments, a separate tripod must be carried for each engineering survey. Tripods are large and long, making them inconvenient to carry and affecting the efficiency of engineering surveying. Furthermore, after supporting the instruments, the overall center of gravity of the equipment is high, resulting in poor stability and wind resistance, which affects the safety of the equipment. Summary of the Invention

[0037] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can also be implemented in various different forms, and therefore the present invention is not limited to the embodiments described below. In addition, for the purpose of more clearly describing the present invention, parts not connected to the invention will be omitted from the drawings.

[0038] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0039] Example 1:

[0040] This embodiment describes the specific structure of a surveying device for engineering surveying, such as... Figures 1-13As shown, the instrument includes a main body 1, an outer shell 2, and an inner shell 3. The inner shell 3 is located inside the outer shell 2. A support ring 31 is located on the top of the inner shell 3 and above the outer shell 2. A multi-stage hydraulic rod 33 is installed inside the outer shell 2 to drive the inner shell 3 to rise and fall. The inner shell 3 has an adjustment mechanism inside to control the rise and fall of the main body 1, used to house the main body 1 within the inner shell 3 for protection. The adjustment mechanism includes a lifting seat 4 and a movable seat 44. The lifting seat 4 slides up and down along the inner wall of the inner shell 3, and the movable seat 44 rotates. The first support group 5 is arranged in a ring array on the outside of the outer shell 2 and is fixedly connected to the bottom of the main body 1 of the surveying instrument. The first support group 5 includes a support plate 51 and a connecting plate 52. The second support group 6 is arranged in a ring array on the outside of the support ring 31. The second support group 6 consists of three sets of interlocking sleeve rods 61. A fixed cover 7 is provided above the support ring 31. A locking mechanism is arranged in a ring array on the outside of the fixed cover 7. The locking mechanism includes a first buckle block 25, a second buckle block 35 and a latch lock 72.

[0041] During surveying, firstly, the first support group 5 is adjusted and controlled to support and fix the support plate 51 to the outer shell 2. Then, the fixing cover 7 is opened to allow the multi-stage hydraulic rod 33 to operate and drive the inner shell 3 to rise and fall, adjusting the inner shell 3 to a suitable height. After that, the second support group 6 is adjusted and controlled to allow the second support group 6, the first support group 5, and the multi-stage hydraulic rod 33 to cooperate with each other to support and fix the inner shell 3. Then, the lifting seat 4 and the movable seat 44 drive the surveying instrument body 1 to move upward, so that the surveying instrument body 1 can be moved above the inner shell 3 for surveying work. In the surveying project, the inner shell 3 and the battery 221 and multi-stage hydraulic rod 33 installed inside the inner shell 3 can lower the overall center of gravity of the equipment and improve its stability. In addition, the second support group 6 and the first support group 5 cooperate to play a good role in wind resistance.

[0042] When moving the equipment, firstly, the main body 1 of the surveying instrument is stored inside the inner shell 3 by the lifting seat 4 and the movable seat 44. Then, the multi-stage hydraulic rod 33 is retracted to move the inner shell 3 downward, storing the inner shell 3 inside the outer shell 2. At the same time, the first support group 5 and the second support group 6 are folded and retracted and fixed to the outside of the outer shell 2, making the first support group 5 and the second support group 6 easy to carry and reducing the handling space. Next, the fixing cover 7 is moved to the top of the support ring 31, and the outer shell 2, the inner shell 3 and the fixing cover 7 are connected and fixed by the first buckle 25, the second buckle 35 and the latch lock 72, so that the main body 1 of the surveying instrument can be carried and surveying work can be carried conveniently.

[0043] like Figure 4 and Figure 5As shown, a protective plate 24 is installed on the inner wall of the outer shell 2. The protective plate 24 is made of high-density foam material. In addition, the support ring 31 is also filled with high-density foam material. This material has good cushioning performance and can protect the main body of the surveying instrument 1 from impact and vibration during transportation.

[0044] The outer casing 2 has a control cavity 22 and a storage cavity 23 inside. The storage cavity 23 is located above the control cavity 22, and a partition is provided between the control cavity 22 and the storage cavity 23 for separation. A battery 221 is installed inside the control cavity 22 near the edge. The battery 221 can supply power to the controller of the multi-stage hydraulic rod 33, which facilitates the control of the operation of the multi-stage hydraulic rod 33 and the adjustment of the height of the inner casing 3.

[0045] The bottom of the outer casing 2 is equipped with a rotatable chassis 26, and the bottom of the chassis 26 is equipped with a ring array of casters 261. The chassis 26 and the casters 261 can drive the outer casing 2 to move, thereby facilitating the overall transport of the equipment. In addition, when the equipment is stored, the second support group 6 on one side can be unfolded, and the second support group 6 can be used as a pull rod to pull the outer casing 2 to move, improving the comfort of transporting the overall equipment.

[0046] like Figure 6 and Figure 7 As shown, the multi-stage hydraulic rod 33 is installed at the center of the control cavity 22. A telescopic rod 331 is provided on the top of the multi-stage hydraulic rod 33. The top of the telescopic rod 331 is fixedly connected to the bottom of the inner shell 3. When the multi-stage hydraulic rod 33 is in operation, the telescopic rod 331 can be controlled to extend and retract, and drive the inner shell 3 to move up and down, thereby adjusting the height of the inner shell 3.

[0047] The movable seat 44 is located at the top center of the lifting seat 4 and is rotatably connected to the lifting seat 4. The bottom of the surveying instrument body 1 is provided with an adjustment seat 11, which is fixedly connected to the movable seat 44 by bolts, so that the movable seat 44 can drive the surveying instrument body 1 to move. When the movable seat 44 rotates, the surveying instrument body 1 can be adjusted to rotate horizontally. In addition, the inner side of the adjustment seat 11 is provided with a foot screw structure, which can adjust the levelness of the surveying instrument body 1. The outer wall of the lifting seat 4 is provided with a ring array of limiting grooves 41, and the inner wall of the inner shell 3 is provided with limiting ridges 42 corresponding to the limiting grooves 41. The lifting seat 4 is slidably connected to the limiting grooves 41 and the limiting ridges 42, thereby limiting the lifting seat 4 and facilitating the lifting seat 4 to drive the movable seat 44 and the surveying instrument body 1 to move up and down.

[0048] A threaded rod 43 is provided on the lifting seat 4 near the left edge, and the threaded rod 43 is threadedly connected to the lifting seat 4. A limit ring 431 is provided on the inner wall of the inner shell 3 near the top. The bottom end of the threaded rod 43 is rotatably connected to the bottom of the inner shell 3, and the top end of the threaded rod 43 is rotatably connected to the limit ring 431. A lever 432 is provided at the bottom of the threaded rod 43 and below the inner shell 3. The lever 432 can drive the threaded rod 43 to rotate, so that the threaded rod 43 moves relative to the lifting seat 4, thereby driving the lifting seat 4 to move up and down.

[0049] like Figure 4 , Figure 8 and Figure 9 As shown, three sets of arrayed storage slots 21 are provided on the outer wall of the outer shell 2, which serve to store the first support group 5 and reduce the space occupied by the first support group 5 after folding. Symmetrically distributed sliding grooves 211 are provided on the inner wall of the storage slots 21 near the top. The first support group 5 is located inside the storage slots 21. Symmetrically distributed sliding rods 511 are provided on the top of the support plate 51. The sliding rods 511 are slidably connected to the sliding grooves 211. A strip groove 512 is provided on the inner side of the support plate 51 near the bottom. A connecting plate 52 is located inside the strip groove 512. One end of the connecting plate 52 is rotatably connected to the side wall of the storage slot 21, and the other end of the connecting plate 52 is rotatably connected to the inner wall of the strip groove 512.

[0050] When the first support group 5 is unfolded, the sliding rod 511 at the top of the support plate 51 slides down along the strip groove 512. At the same time, one end of the connecting plate 52 rotates on the outer shell 2, and the other end of the connecting plate 52 rotates on the support plate 51. When the sliding rod 511 slides to the bottom of the strip groove 512, the support plate 51 is fully unfolded. At this time, the support plate 51 can be supported and fixed on the outside of the outer shell 2, and the caster wheel 261 is separated from the ground to prevent the caster wheel 261 from driving the outer shell 2 to move. At the same time, under the gravity of the outer shell 2 and the equipment as a whole, the bottom end of the support plate 51 can be in close contact with the ground, so that the outer shell 2 has high stability.

[0051] The outer wall of the support ring 31 is provided with connecting seats 32 arranged in a ring array. The top end of the outermost sleeve rod 61 is rotatably connected to the connecting seat 32. The bottom end of the innermost sleeve rod 61 is provided with a plug 62, and the plug 62 has a fixing hole 63. The outer wall of the support plate 51 is provided with a connecting block 53 near the bottom end. A movable sleeve 54 is rotatably connected to the connecting block 53. The plug 62 and the movable sleeve 54 are inserted into each other. A locking screw 55 is threaded onto the movable sleeve 54. The locking screw 55 is connected to the fixing hole 63. The two parts are interlocked to fix the plug 62 and prevent it from detaching from the movable sleeve 54. This facilitates the cooperation between the second support group 6 and the first support group 5 for support and fixation, improving the overall stability and wind resistance of the equipment. In addition, the movable sleeve 54 is made of magnetic material, and the plug 62 can be magnetically attracted to the movable sleeve 54. When the second support group 6 is in the retracted state, it can be quickly restricted and fixed, avoiding repeated tightening of the locking screw 55 and improving the efficiency of equipment use.

[0052] To improve the stability of the second support group 6 during support, spiral blocks are provided on the two outer sets of sleeve rods 61 near the bottom. The spiral blocks are threaded to the side wall of the sleeve rod 61, which can compress and fix the inner sleeve rod 61.

[0053] like Figure 2 and Figure 11 As shown, a sealing ring 71 is provided at the bottom of the fixed cover 7 near the edge, and an annular groove 34 is provided at the top of the support ring 31 near the edge. The sealing ring 71 and the annular groove 34 are engaged. The first buckle block 25 is arranged in an annular array on the outer wall of the outer shell 2, and the second buckle block 35 is arranged in an annular array on the outer wall of the support ring 31, with the second buckle block 35 located directly above the first buckle block 25. The latch lock 72 is arranged in an annular array on the top of the fixed cover 7, and a locking ring 721 is rotatably connected to the edge of the latch lock 72. The locking ring 721 engages with both the first buckle block 25 and the second buckle block 35, thereby connecting and fixing the fixed cover 7 to both the outer shell 2 and the inner shell 3, providing storage and protection for the main body of the surveying instrument 1, and facilitating its carrying.

[0054] The outer shell 2 and the top of the support ring 31, and below the latch lock 72, are both provided with positioning grooves 731. The bottom of the support ring 31 and the fixing cover 7 are both provided with positioning blocks 73 corresponding to the positioning grooves 731. Through the cooperation of the positioning grooves 731 and the positioning blocks 73, the inner shell 3 and the fixing cover 7 can be positioned during storage, so that the locking ring 721 can cooperate with the first buckle block 25 and the second buckle block 35 to fix it at the same time.

[0055] The top of the movable base 44 has rectangularly distributed insertion holes 441. The bottom of the fixed cover 7, located inside the threaded ring 74, has rectangularly distributed sleeves 75. There are four sets of rectangularly distributed fixing rods 76 between the fixed cover 7 and the movable base 44. The bottom end of the fixing rod 76 is inserted into the insertion hole 441, and the top end of the fixing rod 76 is inserted into the sleeve 75. The bottom of the fixed cover 7, located inside the inner shell 3, has a threaded ring 74. When the surveying instrument body 1 is conducting surveying, the two ends of the fixing rod 76 are inserted into the insertion hole 441 and the sleeve 75, which can support the fixed cover 7 above the surveying instrument body 1 and protect the surveying instrument body 1 from direct sunlight, and also provide waterproof and dustproof effects.

[0056] Working principle: During surveying, firstly, the support plate 51 is pulled, causing the slide rod 511 to slide down along the strip groove 512. The two ends of the connecting plate 52 rotate on the outer shell 2 and the support plate 51 respectively, causing the slide rod 511 to gradually slide to the bottom of the strip groove 512, fully unfolding the first support group 5 and supporting and fixing the outer shell 2. Then, the fixing cover 7 is opened, and the multi-stage hydraulic rod 33 operates to adjust the inner shell 3 to a suitable height through the telescopic rod 331. Then, each sleeve rod 61 is pulled in sequence, so that the insert block 62 at the bottom of the innermost sleeve rod 61 is fixedly connected to the movable sleeve 54, so that the first support group 5 and the second support group 6 cooperate with each other to support and fix. Then, the threaded rod 43 is rotated, so that the threaded rod 43 moves relative to the lifting seat 4, so that the lifting seat 4 moves the surveying instrument body 1 above the inner shell 3 through the movable seat 44, so that the surveying instrument body 1 can perform surveying.

[0057] During transport, firstly, the main body 1 of the surveying instrument is stored inside the inner shell 3 by the lifting seat 4 and the movable seat 44, so that the insert 62 is separated from the movable sleeve 54 and the second support group 6 is retracted. Then, the multi-stage hydraulic rod 33 drives the telescopic rod 331 to retract and move the inner shell 3 downward, so that the inner shell 3 moves to the inside of the storage cavity 23. Then, the fixed cover 7 is engaged with the top of the inner shell 3, and the outer shell 2, the inner shell 3 and the fixed cover 7 are connected and fixed by the cooperation of the first buckle 25, the second buckle 35 and the latch lock 72, so that the main body 1 of the surveying instrument is stored and protected. Then, the first support group 5 is stored and folded and engaged with the storage groove 21, so that the insert 62 at the bottom of the innermost sleeve rod 61 is connected to the movable sleeve 54, preventing the first support group 5 and the second support group 6 from moving, thereby facilitating the overall transport and carrying of the equipment.

[0058] Example 2:

[0059] This embodiment is an improvement based on Embodiment 1:

[0060] like Figures 10-13As shown, in order to improve the waterproof and dustproof properties of the surveying instrument body 1 during use and to prevent the equipment from aging due to prolonged direct exposure to ultraviolet rays, an umbrella-type protective mechanism is provided at the bottom of the inner shell 3. The umbrella-type protective mechanism includes a fixing ring 8, which is located on the outside of the threaded ring 74 and is threadedly connected to the outer wall of the threaded ring 74. This allows the umbrella-type protective mechanism to be freely disassembled from the fixing cover 7, facilitating the cleaning of dust on the arc-shaped plate 82 and the umbrella cloth 83 after use. This prevents rainwater or dust from falling into the interior of the inner shell 3 during rain and dust protection. The bottom of the fixing ring 8 is connected to an arc-shaped plate 82 arranged in a ring array. A foldable umbrella cloth 83 is provided between adjacent arc-shaped plates 82. The umbrella cloth 83 is made of black rubber cloth and polyester fiber composite material, which has good waterproof, UV resistance and anti-aging properties.

[0061] A wire ring 81 is installed on the fixed ring 8 near its bottom end. The wire ring 81 passes through the bottom side wall of the fixed ring 8. The top of the arc-shaped plate 82 is rotatably connected to the wire ring 81. The umbrella cloth 83 is placed between adjacent arc-shaped plates 82, and its edge is fixedly connected to the side wall of the arc-shaped plate 82. A control frame 821 is provided on the outer circumference of the arc-shaped plate 82. An adjusting ring 84 is provided on the outer side of the arc-shaped plate 82. The adjusting ring 84 slides up and down along the inner wall of the control frame 821, and the adjusting ring 84 slides to the control frame 821. When the control frame 821 is at its bottom, multiple arc-shaped plates 82 contract into a near-cylindrical shape. When the adjusting ring 84 slides upward, it cooperates with the control frame 821 to drive the arc-shaped plates 82 to gradually unfold outward. When the adjusting ring 84 slides to the top of the control frame 821, the multiple arc-shaped plates 82 unfold into an umbrella shape. Arc-shaped locking blocks are provided on the inner side of the control frame 821 near both ends. The arc-shaped locking blocks can engage with the adjusting ring 84 to fix the adjusting ring 84 at both ends of the control frame 821.

[0062] When the adjusting ring 84 is pushed and slides along the control frame 821, the arc plate 82 rotates on the wire ring 81. When the adjusting ring 84 is at the bottom of the control frame 821, multiple arc plates 82 simultaneously retract into a near-cylindrical shape, and the umbrella cloth 83 folds, allowing the umbrella-type protective mechanism to be housed in the inner shell 3. When the adjusting ring 84 is at the top of the control frame 821, multiple arc plates 82 simultaneously unfold, and the umbrella cloth 83 fully unfolds, so that the umbrella cloth 83, the arc plate 82, and the fixed cover 7 cooperate with each other to form an umbrella-shaped structure, thereby expanding the effective protective area of ​​the surveying instrument body 1 and improving the dustproof, waterproof, and sunshade effects of the surveying instrument body 1.

[0063] The outer side of the fixing ring 8 is provided with symmetrical front and rear pull plates 85. The top of the pull plate 85 is rotatably connected to the outer wall of the fixing ring 8. The bottom end of the pull plate 85 is provided with an integrally formed locking hook 851. The adjusting ring 84 is engaged with the locking hook 851 at the top of the control frame 821. The inner side of the pull plate 85 is provided with a tension spring 852 connected to the outer wall of the fixing ring 8. When the adjusting ring 84 moves to the top of the control frame 821, the locking hook 851 engages with the adjusting ring 84. Under the action of the tension spring 852, the adjusting ring 84 can be fixed, which enhances the stability of the arc plate 82 and prevents the umbrella fabric 83 and the arc plate 82 from folding and affecting the protective effect.

[0064] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
