[0002] In modern building design and construction, curved ramps, as a common building structure, are widely used in various public buildings, commercial complexes, parking lots, underground passages and other places. These ramps not only need to meet basic traffic functions, but also need to ensure the safety and comfort of pedestrians and vehicles. Therefore, it is particularly important to accurately locate and control the spatial elevation of the curved ramps.

[0003] In order to accurately locate and measure, measuring instruments such as total stations and laser rangefinders are used. They can accurately capture the three-dimensional coordinates of each point on the ramp, provide reliable data support for precise construction, and record measurement data in real time. The data can be processed and analyzed through software to provide a scientific basis for the optimization of construction plans.

[0004] When using a total station to measure the spatial elevation of a curved ramp, the measuring rod plays an indispensable role as a key auxiliary tool. However, the use of the measuring rod often requires manual operation. Although manual operation is flexible, there is also the risk of human error.

Therefore, a curved ramp spatial elevation positioning device is proposed to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Furthermore, the support leg 42 passes through and is slidably connected to the top of the positioning plate 4, and the lower end of the support leg 42 is arranged to be inclined. By setting it to be inclined, the stability of the support can be increased. A limit groove 46 is provided on the left side of the support leg 42 to cooperate with a limit block 47 to slide into the limit groove 46 to limit the support leg 42, and multiple groups of limit grooves 46 are provided. The multiple groups of limit grooves 46 are all provided on the left side of the support leg 42. By providing multiple groups, they can be adjusted according to the height of the ground, so that the measuring rod 1 can be stably supported. A slide groove 44 is provided on the inner wall of the positioning plate 4 near the left side of the support leg 42 for the sliding of the limit block 47, and the inner wall of the slide groove 44 is slidably connected with a limit block 47 that slides into the limit groove 46 to limit the support leg 42.

[0035] Reference Figure 1 and Figure 2An adjustment component is set at the upper end of the measuring rod 1, and the adjustment component includes a ball 21 that slides into the circular groove 22 to limit the adjustment rod 2. The ball 21 is slidably connected to the inner wall of the upper end of the measuring rod 1. The right side of the ball 21 is fixedly connected with a slide rod 23 that can drive the ball 21 to slide out of the circular groove 22 by pulling the slide rod 23.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The top right side of the limit block 47 is set as an inclined surface, the limit block 47 is adapted to the limit groove 46, the limit block 47 is elastically connected to the positioning plate 4 through the spring 2 45, one end of the spring 2 45 is fixedly connected to the left inner wall of the slide groove 44, and the other end of the spring 2 45 is fixedly connected to the left side of the limit block 47. The inclined surface of the limit block 47 can be squeezed by moving the support leg 42 downward, so that the limit block 47 moves inward to squeeze the spring 2 45. At this time, the support leg 42 is moved downward to contact the ground for support. At this time, the limit block 47 can be reset and slide into the limit groove 46 through the reverse force of the squeezed spring 2 45, and the support leg 42 can be moved upward to a limit position, so that the measuring rod 1 and the positioning plate 4 can be supported. The top of the limit block 47 is fixedly connected with a guide block 410 for driving the limit block 47 to move. The guide block 410 is slidably connected to the top of the positioning plate 4. The top of the positioning plate 4 is close to the left side of the guide block 410, and the outer side of the measuring rod 1 is rotatably connected with a positioning ring 43 that supports the lever 41 and the guide ring 48.

[0037] Reference Figure 1 , Figure 4 and Figure 5 The outer wall of the positioning ring 43 is fixedly connected to a lever 41 which can drive the guide ring 48 and the extrusion block 49 to move by moving the lever 41. The outer wall of the lever 41 is fixedly connected to a guide ring 48 which supports and drives the extrusion block 49 to move. Through the cooperation of the guide ring 48, the extrusion block 49 and the guide block 410, the limit stops of multiple groups of support legs 42 can be quickly contacted at the same time. The operation is relatively convenient and rapid resetting can be achieved.

[0038] Furthermore, the guide ring 48 is arranged on the left side of the right support leg 42 of the guide block 410, and the inner wall of the guide ring 48 is fixedly connected with a slope of the guide block 410 which can be squeezed by the slope of the squeezing block 49, so that the guide block 410 moves inwardly to drive the limit block 47 to move out of the limit groove 46, and the limit of the support leg 42 can be released at this time, so that the multiple groups of limit blocks 47 can be driven to move by rotating the guide ring 48, and the limit of the multiple groups of support legs 42 can be released. At this time, the multiple groups of support legs 42 can be quickly reset, thereby improving the convenience of operation of the squeezing block 49. The front and rear surfaces of the left side of the squeezing block 49 are both arranged as slopes, and the right side of the guide block 410 is arranged as a slope. The slope of the guide block 410 is squeezed by the slope of the squeezing block 49, so that the guide block 410 moves inwardly to drive the limit block 47 to move out of the limit groove 46, and the limit of the support leg 42 can be quickly released, which is more convenient.

[0039] Reference Figure 1 and Figure 2 The ball 21 is elastically connected to the measuring rod 1 through a spring 24, one end of the spring 24 is fixedly connected to the right side of the ball 21, and the other end of the spring 24 is fixedly connected to the right inner wall of the measuring rod 1. The adjustment is performed by moving the adjusting rod 2, and the circular surface of the ball 21 is squeezed by the adjusting rod 2, so that the ball 21 moves outward to squeeze the spring 24. When the adjusting rod 2 is adjusted to a suitable height, the reverse force of the squeezing of the spring 24 can drive the ball 21 to reset and get stuck in the circular groove 22, so that the adjusting rod 2 is limited. The sliding rod 23 is slidably connected to the right side of the measuring rod 1, and the right side of the adjusting rod 2 is provided with a circular groove 22 for limiting the adjusting rod 2. There are multiple groups of circular grooves 22, and the multiple groups of circular grooves 22 are all provided on the right side of the adjusting rod 2, and the ball 21 slides on the inner wall of the circular groove 22.

[0040] Working principle: When in use, first place the measuring rod 1 at the measuring position, and drive the supporting leg 42 to move downward quickly by stepping on the pedal. During the movement, the inclined surface of the supporting leg 42 squeezes the inclined surface of the limit block 47, pushing the limit block 47 and the connected guide block 410 to move inward, and at the same time compressing the spring 2 45. When the supporting leg 42 contacts the ground and stably supports it, the reverse elastic force of the spring 2 45 pushes the limit block 47 to reset and slide into the corresponding limit groove 46, thereby locking the position of the supporting leg 42 and ensuring the stability of the measuring rod 1 and the positioning plate 4.

[0041] When it is necessary to adjust or retract the measuring rod 1, the operator can rotate the lever 41 on the positioning ring 43, and the lever 41 drives the guide ring 48 and the extrusion block 49 to move. The inclined surface of the extrusion block 49 squeezes the inclined surface of the guide block 410, pushing the guide block 410 and the connected limit block 47 to move inward, so that the limit block 47 slides out of the limit groove 46, releasing the limit on the support leg 42. At this time, the support leg 42 can move upward freely to achieve rapid reset.

[0042] When the height of the adjusting rod 2 and the prism needs to be adjusted, the adjusting rod 2 can be directly moved upwards, and the adjusting rod 2 can squeeze the round surface of the ball 21, so that the ball 21 moves outward to squeeze the spring 24. When the height of the adjusting rod 2 and the prism is adjusted to a suitable position, the ball 21 is snapped into the corresponding circular groove 22 under the action of the reverse elastic force of the spring 24, thereby locking the adjusting rod 2. The operation is relatively convenient, and the measurement efficiency is improved.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
