Description

Technical Field

[0001] This utility model relates to the field of surveying equipment technology, specifically a surveying device. Background Technology

[0002] Construction cost refers to the price of a project. The pricing process involves measurement, estimation, and budgeting. When completing the construction cost estimate, professional engineers need to use surveying equipment to survey the site and measure the entire terrain to more accurately assess the construction cost.

[0003] Existing on-site surveying equipment for engineering cost estimates generally includes a surveying instrument and a tripod. When using it, first, the tripod is set up and placed on the ground at the target location. Then, the surveying instrument is installed on top of the tripod using bolts. Next, the tripod is moved and the length of the tripod legs is adjusted to adjust the height of the surveying instrument until the distance measuring instrument is aligned with the surveying point and is horizontal. On-site surveying can then begin.

[0004] Because the surveying instrument is relatively heavy, the weight of the entire surveying device is mainly concentrated at the top of the tripod. The tripod itself is relatively light, and to ensure stability, the central axis must always be vertical, allowing the weight to be evenly distributed across the three legs. However, since the height of the surveying instrument needs to be adjusted during use, the length of the legs also needs to be adjusted. During this adjustment process, it is inevitable that the tripod needs to be moved, making it impossible to keep the central axis vertical. This can easily cause the tripod to tip over, causing the surveying instrument to fall and potentially damage it. Utility Model Content

[0005] The purpose of this invention is to provide a surveying device to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a surveying device, including a mounting frame and a surveying instrument mounted on the mounting frame. The mounting frame includes a fixed support, and a platform and a lifting device for driving the platform to move up and down are provided on the fixed support. The surveying instrument is mounted on the platform. The lifting device includes several support arms connected to the platform and several drive mechanisms for driving the support arms to move up and down.

[0007] As a further feature of this invention, one end of the support arm is hinged to the platform, and the other end is hinged to a sliding seat. The fixed bracket includes several guide rails, and the driving mechanism is used to drive the sliding seat to slide along the length of the guide rails.

[0008] As a further feature of this invention, the driving mechanism includes a drive motor mounted on a fixed bracket, and a threaded screw is connected to the output end of the drive motor via a transmission assembly. The threaded screw is rotatably connected to a guide rail, and a nut seat threadedly connected to the threaded screw is provided on the sliding seat.

[0009] As a further feature of this invention, a groove is provided on the guide rail along its length, and a slider is provided on the nut seat that is slidably connected inside the groove.

[0010] As a further feature of this invention, the transmission assembly includes a driving bevel gear fixedly connected to the output end of the drive motor and a driven bevel gear fixedly connected to the threaded screw, wherein the driving bevel gear and the driven bevel gear mesh with each other.

[0011] As a further feature of this invention, each support arm includes two support rods, one end of which is rotatably connected to the platform and the other end is rotatably connected to the sliding seat.

[0013] As a further feature of this invention, all the support rods are made of stainless steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the height of the surveying instrument needs to be adjusted, this utility model only needs to drive the support arms to move up and down through the drive mechanism. When all the support arms move simultaneously, the platform can be pushed up or down accordingly, thereby causing the surveying instrument to rise and fall as well, thus achieving the adjustment of the surveying instrument's height. Since the platform always rises and falls vertically along a central axis, the surveying instrument always maintains a vertical rising and falling state, which makes the center of gravity of the surveying device stable, less prone to tipping over, avoids damage to the surveying instrument from falling to the ground, and ensures the stability of the surveying device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 4 As shown, a surveying device includes a mounting frame and a surveying instrument 1 mounted on the mounting frame. The mounting frame includes a fixed support, on which a platform 2 and a lifting device for driving the platform 2 to rise and fall are mounted. The surveying instrument 1 is mounted on the platform 2. The lifting device includes several support arms connected to the platform 2 and several drive mechanisms for driving the support arms to move up and down. When it is necessary to adjust the height of the surveying instrument 1, the support arms are simply driven to move up and down through the drive mechanisms. When all the support arms move simultaneously, the platform 2 can be pushed to rise or fall accordingly, thereby driving the surveying instrument 1 to rise and fall accordingly, thus achieving the adjustment of the height of the surveying instrument 1. Since the platform 2 always rises and falls vertically along a central axis, the surveying instrument 1 always maintains a vertical rising and falling state, thereby making the center of gravity of the surveying device stable, not easy to tip over, avoiding the surveying instrument 1 from falling to the ground and being damaged, and ensuring the placement stability of the surveying device.

[0023] Please see Figure 1-3As shown, one end of the support arm is hinged to the platform 2, and the other end is hinged to a sliding seat 3. The fixed bracket includes several guide rails 4. The drive mechanism is used to drive the sliding seat 3 to slide along the length of the guide rails 4. By driving the sliding seat 3 to slide along the length of the guide rails 4, the support arm can be pushed, causing the support arm to move up and down, thereby driving the platform 2 to rise and fall, and realizing the adjustment of the height of the surveying instrument 1. In this process, due to the limitation of the guide rails 4, the sliding of the sliding seat 3 is relatively smooth, thus making the rise and fall of the surveying instrument 1 relatively smooth, not easy to shake, and the operation is relatively convenient and simple. The drive mechanism includes a drive motor 5 mounted on the fixed bracket. The output end of the drive motor 5 is connected to a threaded screw 6 through a transmission component. The threaded screw 6 is rotatably connected to the guide rails 4, and a nut seat 7 is provided on the sliding seat 3, which is threadedly connected to the threaded screw 6. By starting the drive motor 5, the threaded screw 6 is driven to rotate, thus... The nut seat 7 slides along the length of the threaded screw 6, thereby pushing the support arm and raising and lowering the platform 2 to adjust the height of the surveying instrument 1. This is convenient and efficient. A groove 8 is provided on the guide rail 4 along its length, and a slider 9 is provided on the nut seat 7 and slidably connected inside the groove 8. When the nut seat 7 slides, the slider 9 will slide inside the groove 8. By limiting the slider 9 through the groove 8, the sliding of the nut seat 7 can be made relatively smooth and stable. The transmission component includes a driving bevel gear 10 fixedly connected to the output end of the drive motor 5 and a driven bevel gear 11 fixedly connected to the threaded screw 6. The driving bevel gear 10 and the driven bevel gear 11 mesh with each other. When the drive motor 5 is started, it can drive the driving bevel gear 10 to rotate, which in turn drives the driven bevel gear 11 to rotate, thereby driving the threaded screw 6 to rotate. The transmission is smooth and efficient.

[0024] Please see Figure 1 , Figure 4 As shown, each support arm includes two support rods 12, which are made of stainless steel, with high strength and hardness, and are not easy to rust, and have good durability. One end of the support rod 12 is rotatably connected to the platform 2, and the other end is rotatably connected to the sliding seat 3. The simultaneous action of the two support rods 12 ensures the load-bearing capacity of the support arm, thereby ensuring the support effect of the support arm on the surveying instrument 1, making the surveying instrument 1 more stable when it is raised and lowered. The fixed bracket also includes a base 13, and one end of the guide rail 4 is fixedly connected to the base 13 through a connecting seat, and the other end is connected to a support platform 14. The setting of the base 13 ensures the stability of the fixed bracket, and the support platform 14 can provide support when the platform 2 is lowered to the lowest point.
