Description

Technical Field

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

[0002] The leveling support device for engineering surveying is a widely used piece of equipment in the field of engineering surveying. It is mainly used to support and fix surveying instruments, such as total stations and levels, to ensure that they remain horizontal during measurement work, thereby improving measurement accuracy and efficiency. It can adapt to various complex terrains and ground conditions. In practical applications, the leveling support device for engineering surveying has the advantages of simple operation, high leveling accuracy, and good stability. It can effectively reduce measurement errors caused by instrument tilt, improve the accuracy and reliability of measurement data. In addition, the device has good versatility and adaptability, and can meet the needs of different types of surveying instruments. It is widely used in fields such as construction engineering, road and bridge construction, geological exploration, and topographic surveying.

[0003] According to the Chinese Utility Model Publication No. CN220600972U, a leveling bracket for a land surveying instrument is disclosed. (1) By setting a balance ball, the surveying instrument is fixed on the top of the balance ball. Under the gravity of the counterweight, the balance ball keeps the surveying instrument in a horizontal state. This setting allows the surveying instrument to automatically correct its level, improving the convenience of surveying work. By setting a suction cup and a piston plate, the balance ball can be limited and fixed by suction, preventing the surveying instrument from shaking due to external factors. By setting a screw and a connecting sleeve, the connecting sleeve can be rotated to slide on the surface of the screw. This operation can adjust the height of the surveying instrument, improving the practicality of the device; (2) By setting up support legs, the tips of the bottom of the support legs are inserted into the soil, which makes the device more stable. At the same time, the fixed feet can be retracted to the bottom of the support frame by sliding and retracting. This setting allows the fixed feet to be retracted when the device is carried, preventing the tips of the fixed feet from piercing the staff. By setting up positioning blocks, the positioning blocks can be pulled out from the bottom of the counterweight and inserted into the slot of the fixed platform, which can limit and fix the balance ball when the device is carried or transported, preventing the suction cup from being damaged due to long-term fixation.

[0004] However, there are some issues to consider when implementing the above technical solutions: First, when conducting surveying work in the rain, rainwater will seep into the surveying instrument, causing equipment damage and data inaccuracy, which will seriously affect its normal use. In addition, it will affect observation under strong light. Second, when using it at night, due to low visibility and insufficient light, it is difficult to identify targets, which will reduce the overall surveying efficiency and prolong the operation time.

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.

[0025] Please see Figure 1-4 An embodiment of this utility model is provided: a leveling support device for engineering surveying, including a base 1, an illumination mechanism 3 and a covering mechanism 4. The bottom of the base 1 is hinged with a support leg 2, the illumination mechanism 3 is fixedly connected to the lower outer side of the base 1, and the covering mechanism 4 is fixedly connected to the upper outer side of the base 1.

[0026] Specifically, the lighting mechanism 3 includes a lower bearing 301, a lower collar 302, a lower connecting block 303, a lower connecting groove 304, and a lighting lamp 305. The lower bearing 301 is fixedly connected to the lower outer side of the base 1, and the lower collar 302 is fixedly connected to the outer side of the lower bearing 301. The lower collar 302 forms a rotating structure with the base 1 through the lower bearing 301. The lighting lamp 305 can rotate freely during use through the lower bearing 301, and the lighting position can be adjusted as the scale position moves.

[0027] Specifically, a lower connecting block 303 is welded to the outer side of the lower collar 302, and a lower connecting groove 304 is slidably connected to the outer side of the lower connecting block 303. A lighting lamp 305 is fixedly connected to the right side of the lower connecting groove 304. The lighting lamp 305 can be used at night to provide illumination and improve surveying efficiency. At the same time, it can be disassembled and assembled by the cooperation of the lower connecting block 303 and the lower connecting groove 304, making it easy to carry.

[0028] Specifically, the covering mechanism 4 includes an upper bearing 401, an upper collar 402, an upper connecting block 403, an upper connecting groove 404, a rotating seat 405, an adjusting rod 406, a scissor brace 407, a connecting rod 408, and a light-blocking and waterproof cloth 409. The upper bearing 401 is fixedly connected to the upper outer side of the base 1, and the upper collar 402 is fixedly connected to the outer side of the upper bearing 401. The upper collar 402 forms a rotating structure with the base 1 through the upper bearing 401. The angle of the covering mechanism 4 can be changed through the upper bearing 401 to prevent the adjusting rod 406 from blocking the lens of the surveying instrument and affecting observation.

[0029] Specifically, an upper connecting block 403 is welded to the outer side of the upper collar 402, and an upper connecting groove 404 is slidably connected to the outer side of the upper connecting block 403. A rotating seat 405 is fixedly connected to the right side of the upper connecting groove 404. An adjusting rod 406 is hinged to one side of the rotating seat 405 via a damping pivot. The adjusting rod 406 has three sections, which are connected by the damping pivot. Rotating the adjusting rod 406 can change the position of the light-shielding waterproof cloth 409, which is suitable for use with different surveying instruments and can avoid obstructing the view. At the same time, the damping pivot can prevent the adjusting rod 406 from loosening and facilitates storage.

[0031] Specifically, five connecting rods 408 are provided, and a light-shielding waterproof cloth 409 is fixedly connected to the top of the connecting rods 408. The light-shielding waterproof cloth 409 is larger than the size of the surveying instrument. The light-shielding waterproof cloth 409 can block rainwater in rainy weather to prevent it from falling on the surveying instrument and causing equipment damage and data inaccuracy. At the same time, it can also block the light source in strong light conditions to facilitate observation of the display screen.

[0032] Working principle: During use, the device is leveled using the support leg 2, and then the surveying instrument is installed on the base 1. For nighttime use, the lighting lamp 305 is installed via the lower connecting block 303 and the lower connecting groove 304. The lighting lamp 305 provides illumination at night, improving surveying efficiency. The lower bearing 301 allows the lighting lamp 305 to rotate freely during use, adjusting the illumination position as the scale moves. For use in rainy or bright sunlight conditions, the covering mechanism 4 is installed via the upper connecting block 403 and the upper connecting groove 404. The adjusting rod 406 can then be rotated to change the light-blocking and waterproof cloth. Position 409 is suitable for use with different surveying instruments and can avoid obstructing the view. At the same time, the damping shaft can prevent the adjusting rod 406 from loosening. The scissor brace 407 can change the spacing of the connecting rod 408 to unfold or store the light-blocking waterproof cloth 409. The light-blocking waterproof cloth 409 can block rainwater in rainy weather, preventing it from falling on the surveying instrument and causing equipment damage and data inaccuracy. It can also block the light source in strong light conditions, making it easier to observe the display screen. The upper bearing 401 can change the angle of the covering mechanism 4, preventing the adjusting rod 406 from blocking the surveying instrument lens and affecting observation.
