Description

Technical Field

[0001] This utility model relates to the field of construction surveying equipment technology, and in particular to a surveying and setting-out positioning device for steel structure construction. Background Technology

[0002] Steel structure construction is an important part of the modern construction industry. It is characterized by large component size and high installation accuracy requirements. During the construction process, measurement, setting out and positioning work is carried out throughout the entire process. It is a fundamental link to ensure the overall project quality and safety. The accuracy of measurement and setting out directly affects the subsequent installation and splicing accuracy.

[0003] At steel structure construction sites, workers typically need to use various portable electronic measuring devices, such as infrared rangefinders or total stations, to accurately locate distances, angles, and coordinates. These electronic devices generally rely on LCD screens to display measurement data in real time. Operators need to make judgments and record the data on the screen. Steel structure construction sites are mostly open outdoor environments, especially during daytime operations, where the ambient light is very strong. Direct or reflected sunlight can seriously interfere with the observation of the screen, causing screen glare, insufficient brightness, and unclear data display. In order to see the data clearly, operators have to repeatedly adjust the angle or shield the screen with their hands. This not only reduces measurement efficiency, but more seriously, if the data is misread, it will cause major deviations in subsequent installations, resulting in rework or even safety hazards.

[0004] Currently, although some measuring devices are equipped with simple sunshades, these sunshades often have a fixed structure and limited shading range. They cannot adapt to the varying angles of sunlight at different times of the day (such as midday overhead light and evening oblique light), resulting in poor shading effect at specific angles and failing to fundamentally solve the problem of clear readings in strong outdoor light environments.

[0005] Therefore, this utility model proposes a measuring and setting-out positioning device for steel structure construction to overcome the shortcomings of the prior art. Summary of the Invention

[0006] In view of the problems existing in the measuring and setting-out positioning device for steel structure construction, such as severe glare on the display screen and unclear readings in strong outdoor light environments, and the fixed shading structure that cannot adapt to varying light angles, this utility model aims to provide a measuring and setting-out positioning device for steel structure construction with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a measuring and setting-out locator for steel structure construction, including a lifting platform and an infrared rangefinder installed on the lifting platform. A display screen is connected to one side of the infrared rangefinder. The locator also includes a light-shielding component and an extension component connected to the light-shielding component. The light-shielding component includes a first light-shielding plate, which is installed above the display screen. The extension component includes a connecting plate, a second light-shielding plate, and a third light-shielding plate. The connecting plate is fixed to the first light-shielding plate, and a sliding groove is formed on the connecting plate. The second and third light-shielding plates are respectively installed in the sliding groove by sliding connection, thereby forming a retractable light-shielding structure.

[0008] Preferably, the measuring and setting-out locator for steel structure construction further includes a tripod, and the lifting platform is fixedly installed on the tripod so that the operator can adjust the working height of the entire locator according to the needs of the construction site.

[0009] Preferably, as a convenient installation method, an iron plate is fixedly connected to the first light-shielding plate, and a corresponding magnetic sheet is fixedly connected to the lifting platform. The first light-shielding plate is detachably fixed to the lifting platform through the magnetic attraction between the iron plate and the magnetic sheet. This structure can be quickly assembled and disassembled without tools.

[0010] Preferably, the first light-shielding plate has a U-shaped cover, which can better shield the display screen from above and both sides. The connecting plate is fixed to the open end of the U-shaped cover to close one end of the cover and serve as the mounting base for the expansion component.

[0011] Preferably, in order to lock the sliding position, the second light-shielding plate and the third light-shielding plate are provided with multiple recessed holes, and the connecting plate is provided with a corresponding circular groove. A spring and a round-headed post that can extend under the action of the spring are movably installed in the circular groove. The head shape of the round-headed post is adapted to the shape of the recessed hole so as to achieve selective snap-fit.

[0012] Furthermore, each of the connecting plates has an independent circular groove, and the spring and the round head post are installed in each of the circular grooves, forming two independent locking units. One of the round head posts is used to cooperate with the concave hole of the second light shield, and the other round head post is used to cooperate with the concave hole of the third light shield. The two do not interfere with each other.

[0013] Preferably, the plurality of recessed holes are arranged in an array with equal spacing along the sliding direction of the second light-shielding plate and the third light-shielding plate. This arrangement allows the light-shielding plate to be precisely locked at multiple preset positions during the pulling out or retracting process, providing multi-level adjustment.

[0014] Preferably, as a specific implementation of the locking structure, the cylindrical body of the round-headed post is slidably disposed in the inner hole of the circular groove, and the spring is sleeved on the cylindrical body of the round-headed post. One end of the spring abuts against the bottom of the circular groove, and the other end abuts against the head of the round-headed post or the flange on its cylindrical body, continuously providing an outward elastic thrust.

[0015] Preferably, there are two slides, which are respectively opened on opposite sides of the connecting plate. The second light-shielding plate and the third light-shielding plate are slidably installed in the two slides, so that they can slide to the left and right respectively to achieve the maximum range of lateral light shading.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a light-shielding component, includes a first light-shielding plate with an iron plate on it, and a corresponding magnetic piece on the lifting platform. The first light-shielding plate is fixed to the lifting platform by the magnetic attraction between the iron plate and the magnetic piece, which solves the problems of complicated installation process, need for tools, and inconvenient disassembly of existing external light-shielding devices for measuring equipment. It achieves the technical effect of quick installation, convenient disassembly and assembly, reliable fixation, and not easy loss of the light-shielding component.

[0017] This invention solves the problem that traditional light shields have a single structure, a fixed shading range, and cannot adapt to multi-angle light irradiation at different times by fixing a connecting plate on a first light shield. The connecting plate has a sliding groove, and a second light shield and a third light shield are slidably connected in the sliding groove. This invention allows operators to freely extend and retract the second and third light shields according to actual lighting conditions, flexibly expanding the overall shading range and achieving effective shading from multiple angles.

[0018] This invention solves the problem that adjustable light-shielding plates are prone to positional shifts due to vibrations or unintentional contact after adjustment, leading to unstable light-shielding effects. This is achieved by creating multiple recessed holes on the second and third light-shielding plates and setting a matching circular groove containing a spring and a round-headed column on the connecting plate.

[0022] 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.

[0023] Please refer to Figures 1 to 5 This utility model provides a measuring and setting-out locator for steel structure construction, which aims to solve the problem that the display screen 4 of existing measuring equipment reflects light in strong light, causing unclear readings and affecting construction accuracy and efficiency.

[0024] like Figure 1 As shown, the steel structure construction surveying and layout positioning device includes a tripod 2 and a lifting platform 1 fixedly mounted on the tripod 2. The tripod 2 provides stable ground support for the entire device. The lifting platform 1 is used to adjust the measurement height. An infrared rangefinder 3 is mounted on the lifting platform 1. A display screen 4 is connected to one side of the infrared rangefinder 3. To solve the problem of difficulty in reading the display screen 4 under strong light, the device also includes a light-shielding component 5 and an extension component 6 connected to the light-shielding component 5, such as... Figure 2 and Figure 3As shown, the light-shielding assembly 5 includes a first light-shielding plate 501, which covers the display screen 4. To enable quick installation and removal of the light-shielding assembly 5, an iron plate 502 is fixedly connected to the first light-shielding plate 501, and a magnetic piece 503 is fixedly connected to the lifting platform 1. The first light-shielding plate 501 is detachably fixed to the lifting platform 1 by magnetic attraction between the iron plate 502 and the magnetic piece 503. Preferably, the first light-shielding plate 501 is a U-shaped cover, with the iron plate 502 fixedly connected to the top surface of the U-shaped cover, and the magnetic piece 503 fixedly connected to the top surface of the lifting platform 1 above the display screen 4. Figure 4 and Figure 5 As shown, the extension component 6 includes a connecting plate 604, a second light-shielding plate 601, and a third light-shielding plate 602. The connecting plate 604 is fixed to the first light-shielding plate 501. When the first light-shielding plate 501 is a U-shaped cover, the connecting plate 604 is fixed to the open end of the U-shaped cover. The connecting plate 604 is provided with a sliding groove 603 for the second light-shielding plate 601 and the third light-shielding plate 602 to slide. The second light-shielding plate 601 and the third light-shielding plate 602 are slidably connected in the sliding groove 603, so that they can extend or retract to flexibly adjust the light-shielding area. As a specific embodiment, there are two sliding grooves 603, which are respectively opened on opposite sides of the connecting plate 604. The second light-shielding plate 601 and the third light-shielding plate 602 are slidably installed in the two sliding grooves 603.

[0025] To achieve flexible adaptation to different light angles, the core of the technical solution in this embodiment lies in the sliding adjustment and positioning locking structure of the extension component 6, which ensures that the light-blocking range remains stable after adjustment.

[0026] Please refer to the following carefully. Figure 4 and Figure 5 The locking structure of this core will be described in detail below: The connecting plate 604 in the extension component 6 has a circular groove 606, which houses a spring 607 and a round-headed post 608. Specifically, the post body of the round-headed post 608 is slidably disposed in the circular groove 606, and the spring 607 is sleeved on the post body of the round-headed post 608 and abuts against the bottom of the circular groove 606 and the round-headed post 608. The spring 607 always applies an outward elastic thrust to the round-headed post 608.

[0027] Meanwhile, the second light-shielding plate 601 and the third light-shielding plate 602 are respectively provided with a plurality of recessed holes 605. In a preferred embodiment, the plurality of recessed holes 605 are arranged in an array with equal spacing along the sliding direction of the second light-shielding plate 601 and the third light-shielding plate 602. When the second light-shielding plate 601 or the third light-shielding plate 602 is slidably adjusted, the head of the round-headed post 608 will meet the opening of a certain recessed hole 605 on the travel path under the elastic force of the spring 607 and automatically engage, thereby achieving selective engagement. This engagement structure provides a clear sense of the adjustment position and ensures that the light-shielding plate can be firmly locked in any adjustment position, avoiding accidental sliding.

[0028] To enable independent control of the second light-shielding plate 601 and the third light-shielding plate 602, the connecting plate 604 is provided with circular grooves 606. A spring 607 and a round-headed post 608 are installed in each of the circular grooves 606. One of the round-headed posts 608 is engaged with the recessed hole 605 of the second light-shielding plate 601, and the other round-headed post 608 is engaged with the recessed hole 605 of the third light-shielding plate 602.

[0029] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to provide a stable and adjustable measurement base, the steel structure construction measurement and layout positioning device also includes a tripod 2, with the lifting platform 1 fixedly installed on the tripod 2. The operator can flexibly adjust the vertical position of the infrared rangefinder 3 according to the baseline height of the construction site.

[0030] In a preferred embodiment, in order to achieve rapid installation and disassembly of the light-shielding component 5 and improve on-site deployment efficiency, an iron plate 502 is fixedly connected to the first light-shielding plate 501, and a magnet 503 is fixedly connected to the corresponding position on the lifting platform 1. The first light-shielding plate 501 is detachably fixed to the lifting platform 1 through the magnetic adsorption between the iron plate 502 and the magnet 503.

[0031] In a preferred embodiment, in order to make the first light-shielding plate 501 have better structural coverage, the body of the first light-shielding plate 501 is constructed as a U-shaped cover, which has a top surface and two side surfaces extending downward from the top surface. The connecting plate 604 is laterally fixed to the opening end of the U-shaped cover, thereby closing the opening end and providing a mounting base for the second light-shielding plate 601 and the third light-shielding plate 602.

[0032] In a preferred embodiment, in order to enable the second light-shielding plate 601 and the third light-shielding plate 602 to slide independently to the outside, two sliding grooves 603 are provided on the connecting plate 604. These two sliding grooves 603 are respectively provided on opposite sides of the connecting plate 604, and the second light-shielding plate 601 and the third light-shielding plate 602 are respectively slidably installed in these two sliding grooves 603.

[0033] The working principle of this utility model's measuring and setting-out positioning device for steel structure construction is as follows: When used on a steel structure construction site, the operator first unfolds and fixes the tripod 2, adjusts the lifting platform 1 to a suitable height, and then starts the infrared rangefinder 3 to take measurements. The measurement data is displayed on the display screen 4 in real time.

[0034] When working in a bright light environment, it is difficult for the operator to see the data on the display screen 4. At this time, the first light shield 501 of the light shield assembly 5 is brought close to the lifting platform 1. The iron plate 502 on the first light shield 501 and the magnetic piece 503 on the lifting platform 1 will automatically attract each other due to magnetic force, thereby detachably fixing the first light shield 501 above the display screen 4 and covering it to block the strong light from the top.

[0035] If there is interference from side or oblique light, the operator can pull the second light shield 601 or the third light shield 602 of the extension component 6. The second light shield 601 and the third light shield 602 will then slide outward along the sliding groove 603 in the connecting plate 604 fixed on the first light shield 501. During the sliding process, the round-headed post 608 installed in the circular groove 606 of the connecting plate 604 will slide its head through the multiple recesses 605 opened on the second light shield 601 or the third light shield 602 under the elastic thrust of the spring 607. When the pulling stops, the head of the round-headed post 608 will automatically engage with the nearest recess 605, achieving selective engagement, thereby firmly locking the extended second light shield 601 or the third light shield 602 in the current position and preventing it from retracting. Through this retractable and locking structure, the device can adapt to light irradiation at different times and angles, always ensuring the display clarity of the display screen 4 and solving the problem of data misreading under strong light.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
