Description

A total station for road engineering Technical Field

[0001] This utility model belongs to the field of road engineering technology, and specifically relates to a total station for road engineering. Background Technology

[0002] Road engineering mainly studies the design, construction, maintenance and management of various types of roads. Its goal is to provide safe, efficient, economical and environmentally friendly transportation infrastructure for mankind. Total stations are used in the design and construction process. A total station is a high-tech measuring instrument that integrates optics, mechanics and electronics. It is a surveying instrument system that integrates the functions of measuring horizontal angle, vertical angle, distance (slope distance, horizontal distance) and elevation difference.

[0003] When using total stations in road construction projects, they are usually placed in open outdoor environments. Due to direct sunlight, it is difficult for staff to clearly observe the data on the screen. They often need to use sunshade equipment or manually block the sunlight, which seriously affects work efficiency and brings many inconveniences to the operation and recording of the total station. Summary of the Invention

[0004] In view of this, the present invention provides a total station for road engineering, which can cover the top of the total station's operating screen through a light-shielding mechanism, effectively blocking sunlight or other strong light sources from directly shining on the screen, ensuring that operators can still clearly observe the screen data in strong outdoor light environments, and significantly improving the accuracy and efficiency of operation recording.

[0005] To solve the above-mentioned technical problems, this utility model provides a total station for road engineering, including a total station and a light-shielding mechanism set on both sides of its upper end. The light-shielding mechanism includes telescopic folding covers symmetrically arranged on both sides of the upper end of the total station. Both ends of the upper part of the total station are provided with sliding holes, and a sliding rod is slidably connected to one end of each sliding hole. The outer ends of the two sliding rods are fixedly connected to the adjacent telescopic folding covers on the same side. The ends of the sliding holes away from the sliding rods are slidably connected to sliding cylinders, and the outer ends of the two sliding cylinders are fixedly connected to the adjacent telescopic folding covers on the same side. Both ends of the upper part of the total station are also provided with synchronization components, which can cover the top of the total station's operating screen, effectively blocking sunlight or other strong light sources from directly shining on the screen, ensuring that the operator can still clearly observe the screen data in strong outdoor light environments, and significantly improving the accuracy and efficiency of operation recording.

[0006] The synchronization component includes fixed rods respectively set at both ends of the telescopic folding cover. The outer ends of the fixed rods are rotatably connected to connecting plates. The upper ends of the total station are provided with sliding grooves, and sliders are slidably connected in the sliding grooves. The two ends of the outer side of the sliders are rotatably connected to the inner ends of the connecting plates adjacent to the same side, which plays the role of synchronous transmission.

[0007] The synchronization component also includes lead screws that are rotatably connected in the slide grooves. The lead screws are threadedly connected to the threaded holes on the sliders located in the same slide grooves, thus providing a driving source for the sliders.

[0008] It also includes a drive assembly, which includes mounting cavities located at both ends of the upper part of the total station. A rotating rod is rotatably connected between the two mounting cavities. Each rotating rod is provided with a bevel gear one on the outer arc surface of the inner cavity of the mounting cavity. The lower end of each screw extends into the vertically adjacent mounting cavity, and a bevel gear two is provided at each end. The bevel gear two meshes with the bevel gear one located in the same mounting cavity, thus playing the role of synchronous drive.

[0009] The telescopic folding covers are located above each operating screen on the total station, ensuring a light-blocking effect on the operating screens.

[0010] The inner diameter of the slide tube is larger than the diameter of the slide rod, which ensures that the two can move and interlock to avoid each other.

[0011] The small ends of the bevel gears face the same direction to ensure consistent transmission.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. When the two sliders move synchronously, power is transmitted to the outer end of the telescopic folding cover through the rotating connecting plate and fixed rod. At the same time, the sliding rods and sliding cylinders on both sides of the upper end of the total station slide synchronously in the sliding holes, driving the telescopic folding cover to unfold or retract. Since the rotation direction of the lead screws on both sides is consistent and synchronous transmission is achieved through bevel gear one and bevel gear two, the telescopic folding covers on both sides always maintain symmetrical movement, accurately covering the top of the total station's operating screen. When unfolded, the telescopic folding cover forms a light-shielding cover, effectively blocking sunlight or other strong light sources from directly hitting the screen, ensuring that the operator can still clearly observe the screen data in strong outdoor light environments, significantly improving the accuracy and efficiency of operation recording. When retracted, the telescopic folding cover folds and stores, avoiding interference with other operations, achieving rapid and accurate light shielding of the operating screen, solving the problem of strong outdoor light interference, while taking into account structural compactness and adaptability, providing efficient and reliable equipment support for road engineering surveying.

[0014] 2. When it is necessary to block strong light, the drive rotating rod rotates, causing the bevel gears at both ends to rotate synchronously. When the bevel gear rotates, it drives the lead screw to rotate synchronously through the bevel gear connected to it. When the lead screw rotates, it drives the slider connected to it by threads to move along the slide groove, thus playing a synchronous driving role. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to Figures 1-4. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the scope of protection of this utility model.

[0021] This embodiment provides a total station for road engineering, as shown in Figures 1-4: it includes a total station 100 and a light-shielding mechanism disposed on both sides of its upper end. The light-shielding mechanism includes telescopic folding covers 200 symmetrically disposed on both sides of the upper end of the total station 100. Both ends of the upper part of the total station 100 are provided with sliding holes 201. One end of each sliding hole 201 is slidably connected to a sliding rod 202. The outer ends of the two sliding rods 202 are fixedly connected to the adjacent telescopic folding covers 200 on the same side. The end of each sliding hole 201 away from the sliding rod 202 is slidably connected to a sliding cylinder 203. The outer ends of the two sliding cylinders 203 are fixedly connected to the adjacent telescopic folding covers 200 on the same side. Both ends of the upper part of the total station 100 are also provided with synchronization components. The telescopic folding covers 200 are respectively located above each operating screen on the total station 100. The inner diameter of the sliding cylinder 203 is larger than the diameter of the sliding rod 202.

[0022] When the synchronization component moves, it transmits power to the outer end of the telescopic folding cover 200 through the rotating connecting plate 301 and the fixed rod 300. At the same time, the sliding rods 202 and sliding cylinders 203 on both sides of the upper end of the total station slide synchronously in the sliding holes 201, driving the telescopic folding cover 200 to unfold or retract. Due to the synchronous transmission achieved by the synchronization component, the telescopic folding covers 200 on both sides always maintain symmetrical movement, accurately covering the top of the total station's operating screen. When unfolded, the telescopic folding cover 200 forms a light-shielding cover, effectively blocking sunlight or other strong light sources from directly hitting the screen, ensuring that the operator can still clearly observe the screen data in strong outdoor light environments, significantly improving the accuracy and efficiency of operation recording. When retracted, the telescopic folding cover 200 folds and stores, avoiding interference with other operations, achieving rapid and accurate light shielding of the operating screen, solving the problem of strong outdoor light interference, while also taking into account structural compactness and adaptability, providing efficient and reliable equipment support for road engineering surveying.

[0023] As shown in Figures 1-4, the synchronization component includes fixed rods 300 respectively disposed at both ends of the outer side of the telescopic folding cover 200. The outer ends of the fixed rods 300 are rotatably connected to connecting plates 301. The upper ends of the total station 100 are provided with slide grooves 302. Slider blocks 303 are slidably connected in the slide grooves 302. The outer ends of the sliders 303 are rotatably connected to the inner ends of the connecting plates 301 on the same side. The synchronization component also includes lead screws 304 rotatably connected in the slide grooves 302. The lead screws 304 are threadedly connected to the threaded holes provided on the sliders 303 located in the same slide groove 302.

[0024] When the lead screw 304 rotates, it drives the slider 303, which is threadedly connected to it, to move along the slide groove 302. At the same time, after the slider 303 moves into place, it can be limited by the characteristics of the threaded connection.

[0025] As shown in Figure 2-4, the system also includes a drive assembly. The drive assembly includes mounting cavities 400 located at both ends of the upper part of the total station 100. A rotating rod 401 is rotatably connected between the two mounting cavities 400. Each rotating rod 401 is provided with a bevel gear 402 on the outer arc surface of the inner cavity of the mounting cavity 400. The lower end of the lead screw 304 extends into the vertically adjacent mounting cavities 400, and a bevel gear 403 is provided at each end. The bevel gear 403 meshes with the bevel gear 402 located in the same mounting cavity 400. The small ends of the bevel gears 402 face the same direction.

[0026] When it is necessary to block strong light, the drive rotating rod 401 rotates, causing the bevel gear 402 at both ends to rotate synchronously. When the bevel gear 402 rotates, it drives the lead screw 304 to rotate synchronously through the bevel gear 403 that meshes with it, thus playing the role of synchronous drive.

[0027] The working principle of the total station for road engineering provided by this utility model is as follows: When it is necessary to block strong light, the drive rotating rod 401 rotates, causing the bevel gears 402 at both ends to rotate synchronously. When the bevel gear 402 rotates, it drives the lead screw 304 to rotate synchronously through the bevel gear 403 meshing with it. When the lead screw 304 rotates, it drives the slider 303 threadedly connected to it to move along the slide groove 302. When the two sliders 303 move synchronously, they transmit power to the outer end of the telescopic folding cover 200 through the rotating connecting plate 301 and the fixed rod 300. At the same time, the slide rods 202 and slide cylinders 203 on both sides of the upper end of the total station slide synchronously in the slide hole 201, driving the telescopic folding cover 200 to unfold or retract. The two lead screws 304 rotate in the same direction and are synchronously transmitted through bevel gear 402 and bevel gear 403. The telescopic folding covers 200 on both sides always maintain symmetrical movement, accurately covering the top of the total station's operating screen. When unfolded, the telescopic folding covers 200 form a light-shielding cover, effectively blocking sunlight or other strong light sources from directly hitting the screen, ensuring that operators can still clearly observe the screen data in strong outdoor light environments, significantly improving the accuracy and efficiency of operation recording. When retracted, the telescopic folding covers 200 fold and store, avoiding interference with other operations, achieving rapid and accurate light shielding of the operating screen, solving the problem of strong outdoor light interference, while also taking into account structural compactness and adaptability, providing efficient and reliable equipment support for road engineering surveying.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
