Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping, and particularly relates to a precisely leveling surveying and mapping device. Background Technique

[0002] Surveying and mapping is a technology that uses scientific methods and professional equipment to measure and depict the terrain, ground features, geographical locations, etc. of the earth's surface and near-earth space. Currently, when conducting surveying and mapping, special surveying instruments are required, and when using surveying instruments, they need to be precisely leveled to ensure the accuracy of surveying and mapping;

[0003] For existing precisely leveling surveying and mapping devices, most of them place a tripod on the ground, and then the operator repeatedly adjusts the lengths of the three legs of the tripod to adjust the levelness of the surveying instrument. This makes the leveling operation cumbersome and not precise enough, which will not only reduce work efficiency but also affect the accuracy of surveying and mapping results. Content of the Utility Model

[0004] In view of this, the utility model provides a precisely leveling surveying and mapping device, which can achieve multi-angle adjustment of the surveying instrument through the coordinated cooperation of a rotating frame and an arc-shaped sliding plate, and can quickly and accurately complete the horizontal leveling of the surveying instrument, improving the efficiency and accuracy of field surveying and mapping work.

[0005] To solve the above technical problems, the utility model provides a precisely leveling surveying and mapping device, including an assembly box and a rotating frame rotatably connected to the front and rear wall surfaces of the assembly box. A gear is rotatably connected between the left and right wall surfaces of the rotating frame. An installation rod is provided at the upper end of the gear. A through-opening is provided in the middle of the upper surface of the assembly box. The installation rod passes through the through-opening and an installation seat is provided at the end. An arc-shaped sliding plate is slidably connected to the bottom wall surface of the assembly box. An arc-shaped tooth plate is provided inside the arc-shaped sliding plate. The arc-shaped tooth plate meshes with the gear, that is, it can achieve multi-angle adjustment of the surveying instrument, quickly and accurately complete the horizontal leveling of the surveying instrument, and improve the efficiency and accuracy of field surveying and mapping work.

[0006] The front and rear wall surfaces of the assembly box are rotatably connected with a screw rod below the rotating frame. The screw rod is threadedly connected with a corresponding screw hole on the arc-shaped sliding plate, that is, it can move the arc-shaped sliding plate and the arc-shaped tooth plate.

[0007] The teeth on the arc-shaped tooth plate are evenly distributed along the axis of the arc-shaped sliding plate, that is, it can not only rotate the gear but also relatively slide with the gear.

[0008] The gear is a sector gear.

[0009] It also includes a limiting mechanism for limiting the rotating frame. The limiting mechanism includes a chute provided at one end of the rotating frame. A knob is slidably connected in the chute. A slider is provided on the outer arc surface of the end of the knob close to the chute. A sliding port slidably connected to the slider is provided on the inner arc surface of the chute. A first crown gear is provided at the end of the slider passing through the sliding port. A second crown gear is provided on the wall surface of the inner cavity of the assembly box close to the first crown gear. The second crown gear is movably engaged with the first crown gear, ensuring that the surveying and mapping device is stably maintained at the leveled angle.

[0010] The limiting mechanism further includes a spring provided between the opposite inner side surfaces of the knob and the chute, which can provide elastic support for the knob and its attached mechanism.

[0011] An expansion protective cover is provided between the opposite inner side surfaces of the assembly box and the mounting seat, which can protect the part between the assembly box and the mounting seat and does not affect the movement of each component at the same time.

[0012] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0013] 1. The operator places the surveying and mapping device at the required measurement location, ensures the stability of the assembly box, then installs the surveying instrument through the mounting seat, and then observes the bubble level to judge the direction and degree of adjustment required. When rotating the rotating frame, it drives the gear, the mounting rod, the mounting seat and the surveying instrument thereon to rotate synchronously until the mounting seat moves to the horizontal angle. When driving the arc-shaped sliding plate and the arc-shaped tooth plate to move, the arc-shaped tooth plate drives the mounting rod, the mounting seat and the surveying instrument thereon to rotate synchronously through the gear, so that multi-angle adjustment of the surveying instrument can be realized until the bubble level shows completely horizontal, and the horizontal leveling of the surveying instrument can be completed quickly and accurately, improving the efficiency and accuracy of field surveying and mapping work.

[0014] 2. When rotating the rotating frame, the operator presses the knob, and the knob, the slider and the second crown gear move into the chute, finally separating the second crown gear from the first crown gear. After the mounting seat moves to the horizontal angle, the operator releases the knob, and the knob, the slider and the second crown gear are reset, causing the first crown gear to be movably engaged, thereby locking the rotating frame and its attached mechanism, ensuring that the surveying and mapping device is stably maintained at the leveled angle.

[0015] 3. The expansion protective cover can protect the part between the assembly box and the mounting seat and does not affect the movement of each component at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-4 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.

[0022] This embodiment provides an accurate leveling surveying device, as Figures 1-4 shown: It includes an assembly box 100 and a rotating frame 101 rotatably connected to the front and rear wall surfaces of the assembly box 100. A triangular support is rotatably connected to the bottom of the assembly box 100. A gear 102 is rotatably connected between the left and right wall surfaces of the rotating frame 101. An installation rod 103 is provided at the upper end of the gear 102. A through-opening is provided in the middle of the upper surface of the assembly box 100. The installation rod 103 passes through the through-opening and has a mounting seat 104 at its end. Bubble spirit levels evenly distributed in a ring are provided at the edge of the upper surface of the mounting seat 104. The mounting seat 104 is used for installing a surveying instrument. An arc-shaped sliding plate 105 is slidably connected to the bottom wall surface of the assembly box 100. An arc-shaped tooth plate 106 is provided inside the arc-shaped sliding plate 105. The arc-shaped tooth plate 106 meshes with the gear 102.

[0023] The operator places the surveying device at the desired measurement location, ensures that the assembly box 100 is stable, and then installs the surveying instrument through the mounting base 104. The operator then observes the bubble level to determine the direction and degree of adjustment required. When the rotating frame 101 is rotated, the gear 102, the mounting rod 103, the mounting base 104 and the surveying instrument thereon are driven to rotate synchronously until the mounting base 104 moves to a horizontal angle. When the arc-shaped sliding plate 105 and the arc-shaped tooth plate 106 are driven to move, the arc-shaped tooth plate 106 drives the mounting rod 103, the mounting base 104 and the surveying instrument thereon to rotate synchronously through the gear 102, thereby realizing multi-angle adjustment of the surveying instrument until the bubble level shows that it is completely horizontal. The horizontal leveling of the surveying instrument can be completed quickly and accurately, thereby improving the efficiency and accuracy of field surveying work.

[0024] like Figures 2-4 As shown, the front and rear walls of the assembly box 100 are located below the rotating frame 101 and are rotatably connected to a screw rod 107. The front and rear walls of the assembly box 100 are located below the rotating frame 101 and are both provided with a rotating hole 2 for providing rotation support for the screw rod 107. The screw rod 107 is threadedly connected to the corresponding threaded hole on the arc-shaped sliding plate 105. When the screw rod 107 is rotated, the arc-shaped sliding plate 105 and the arc-shaped tooth plate 106 are driven to move under the influence of the threaded connection relationship between the screw rod 107 and the threaded hole.

[0025] like Figures 2-4 As shown, the teeth on the arc-shaped tooth plate 106 are evenly distributed along the axis of the arc-shaped sliding plate 105, and can drive the gear 102 to rotate while also being able to slide relative to the gear 102.

[0026] like Figures 2-3 As shown, the gear 102 is a sector gear.

[0027] Such as Figures 2-4 As shown, it also includes a limiting mechanism, which is used to limit the rotating frame 101. The limiting mechanism includes a slide 200 arranged at one end of the rotating frame 101, and a knob 201 is slidably connected in the slide 200. A slider 202 is provided on the outer arc surface of the end of the knob 201 near the slide 200, and the inner arc surface of the slide 200 is provided with a sliding mouth slidably connected to the slider 202. The end of the slider 202 passing through the sliding mouth is provided with a crown tooth 1 203, and a crown tooth 204 is provided on the wall surface of the inner cavity of the assembly box 100 near the crown tooth 1 203. The crown tooth 204 is movably engaged with the crown tooth 1 203. The crown tooth 204 and the crown tooth 1 203 are both annular and movably sleeved with the end of the rotating frame 101.

[0028] When rotating the rotary frame 101, the operator presses the knob 201. The knob 201, the slider 202 and the second crown gear 204 move into the chute 200, and finally the second crown gear 204 is separated from the first crown gear 203. After the mounting seat 104 moves to the horizontal angle, the operator releases the knob 201, and the knob 201, the slider 202 and the second crown gear 204 are reset, so that the first crown gear 203 is actively engaged, thereby locking the rotary frame 101 and its attached mechanism to ensure that the surveying and mapping device is stably maintained at the leveled angle.

[0029] As Figures 2-4 shown, the limiting mechanism further includes a spring 205 arranged between the relative inner side surfaces of the knob 201 and the chute 200. When pressing the knob 201, the knob 201, the slider 202 and the second crown gear 204 move into the chute 200 against the elastic force of the spring 205. When releasing the knob 201, the knob 201, the slider 202 and the second crown gear 204 immediately make the first crown gear 203 actively engaged under the action of the return elastic force of the spring 205. The spring 205 can provide elastic support for the knob 201 and its attached mechanism.

[0030] As Figures 1-2 shown, a telescopic protective cover 300 is provided between the relative inner side surfaces of the assembly box 100 and the mounting seat 104. The telescopic protective cover 300 can protect the part between the assembly box 100 and the mounting seat 104, and at the same time does not affect the movement of each component.

[0031] The working principle of a precise leveling surveying device provided by the present utility model is as follows: The operator places the surveying device at the location to be measured, ensures that the assembly box 100 is stable, then installs the surveying instrument through the mounting seat 104, and then observes the bubble level to determine the direction and degree of adjustment required. When it is necessary to rotate the rotating frame 101, the operator presses the knob 201. The knob 201, the slider 202, and the second crown gear 204 then move into the chute 200 against the elastic force of the spring 205, and finally the second crown gear 204 is separated from the first crown gear 203. Then, the rotating frame 101 is rotated by turning the knob 201. When the rotating frame 101 rotates, it drives the gear 102, the mounting rod 103, the mounting seat 104, and the surveying instrument thereon to rotate synchronously. After the mounting seat 104 moves to the horizontal angle, the operator releases the knob 201. The knob 201, the slider 202, and the second crown gear 204 then immediately cause the first crown gear 203 to engage actively under the action of the restoring elastic force of the spring 205, thereby locking the rotating frame 101 and its attached mechanisms to ensure that the surveying device is stably maintained at the leveled angle. During this process, the gear 102 slides relative to the arc-shaped tooth plate 106. When the rotating screw 107 is rotated, due to the threaded connection relationship between the screw 107 and the threaded hole, the arc-shaped sliding plate 105 and the arc-shaped tooth plate 106 are driven to move. When the arc-shaped tooth plate 106 moves, it drives the mounting rod 103, the mounting seat 104, and the surveying instrument thereon to rotate synchronously through the gear 102, enabling multi-angle adjustment of the surveying instrument until the bubble level shows complete horizontality, quickly and accurately completing the leveling of the surveying instrument, improving the efficiency and accuracy of field surveying work. The telescopic protective cover 300 can protect the part between the assembly box 100 and the mounting seat 104, and at the same time does not affect the movement of each component.

[0032] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
