Description

Technical Field

[0001] This utility model relates to the field of steel structure installation technology, and in particular to a measuring and positioning device for the installation of curved roof steel structures. Background Technology

[0002] Curved roof steel structures are roof structure systems with curved or arc-shaped profiles. The streamlined curved design enhances the modernity and visual impact of the building. Primarily made of steel, they are formed into smooth arc or curve shapes through special design and construction processes. They are widely used in buildings requiring large spans, modern architectural designs, or special aesthetic effects. During the installation of curved roof steel structures, to ensure accurate positioning, measuring devices are needed to ensure that the distance between adjacent steel structures is basically the same. However, most existing curved roof steel structure installation measuring and positioning devices still have problems that need to be solved.

[0003] In the existing technology, most of the measurement and positioning devices for the installation of curved roof steel structures generally use laser rangefinders to measure the distance between two steel structures. These rangefinders are usually handheld by workers, and handheld operation is easily affected by the operator's stability, which may lead to inaccurate measurement results. Therefore, it is urgent to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a measurement and positioning device for the installation of curved roof steel structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A measuring and positioning device for installing a curved roof steel structure includes a steel structure. An installation plate is mounted on one side of the steel structure. Two sliders are slidably connected to the installation plate. A fixing plate is fixedly connected to one side of each slider. The fixing plate is adapted to the steel structure. A movable plate is located inside the installation plate. Two sleeves are fixedly connected to one side of the movable plate. Insert rods are slidably connected to the inner walls of the sleeves. The insert rods are fixedly connected to the installation plate. The sleeves and insert rods are fitted with the same spring. A connecting plate is fixedly connected to one side of the movable plate. Two pins are fixedly connected to the connecting plate on the side away from the movable plate. The two pins are fitted with the same limiting plate. The limiting plate has two slots that mate with the pins. A laser rangefinder is fixedly connected to the limiting plate. A fixing frame is fixedly connected to one side of the installation plate. The laser rangefinder is housed within the fixing frame. The device utilizes two adjustable... This technology, which fixes the position of the plate while simultaneously restricting the position of the laser rangefinder, secures the device when the plate contacts the steel structure. When the slider moves to the vertical surface of the moving plate, the pin inserts into the slot, thus restricting the position of the laser rangefinder and allowing it to be installed. This effectively solves the problem mentioned in the background section where existing measurement and positioning devices for curved roof steel structures typically use laser rangefinders to measure the distance between two steel structures. These rangefinders are usually handheld, and handheld operation is susceptible to inaccuracies due to the operator's instability. This technology effectively fixes the position of the laser rangefinder, preventing shaking or displacement during manual operation, improving measurement and positioning stability, significantly enhancing measurement accuracy, and facilitating easy disassembly and maintenance of the laser rangefinder.

[0006] As a further embodiment of this utility model, a positioning block is fixedly connected to one side of the laser rangefinder, and a positioning groove adapted to the positioning block is provided on the fixing frame.

[0007] As a further embodiment of this utility model, the mounting plate is provided with a mounting groove, and the movable plate, sleeve, plug rod, and spring are all disposed in the mounting groove. The movable plate and the connecting plate are slidably connected to the mounting plate.

[0008] As a further embodiment of this utility model, a bidirectional lead screw is provided on the mounting plate, the bidirectional lead screw is rotatably connected to the mounting plate, and lead screw nuts are sleeved on both ends of the bidirectional lead screw. The lead screw nuts are adapted to the bidirectional lead screw, and the lead screw nuts are fixedly connected to the slider.

[0009] As a further embodiment of this utility model, a worm gear is fixedly connected to the top of the bidirectional lead screw, a worm is provided on one side of the worm gear for cooperation with it, and a knob is fixedly connected to one side of the worm.

[0010] As a further embodiment of this utility model, both ends of the worm are fitted with fixed seats, the fixed seats are fixedly connected to the mounting plate, and the worm is rotatably connected to the fixed seats.

[0011] The beneficial effects of this utility model are as follows: Because it employs a technique that adjusts the positions of two fixed plates while simultaneously restricting the position of the laser rangefinder, the device can be secured when the fixed plates contact the steel structure. When the slider moves to the vertical surface of the moving plate, the pin can be inserted into the slot, thus restricting the position of the laser rangefinder and installing it. This effectively solves the problem mentioned in the background art that most existing measurement and positioning devices for curved roof steel structures generally use laser rangefinders to measure the distance between two steel structures. Typically, workers hold the laser rangefinder by hand, which is susceptible to inaccurate measurement results due to the operator's instability. This device effectively fixes the position of the laser rangefinder, avoiding shaking or displacement during manual operation, improving the stability of measurement and positioning, significantly improving measurement accuracy, and facilitating the disassembly and maintenance of the laser rangefinder.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-6 A measuring and positioning device for installing a curved roof steel structure includes a steel structure 1. An installation plate 2 is mounted on one side of the steel structure 1. Two sliders 3 are slidably connected to the installation plate 2. A fixing plate 4 is fixedly connected to one side of each slider 3. The fixing plate 4 is adapted to the steel structure 1. A movable plate 5 is installed inside the installation plate 2. Two sleeves 6 are fixedly connected to one side of the movable plate 5. Insert rods 7 are slidably connected to the inner walls of the sleeves 6. The insert rods 7 are fixedly connected to the installation plate 2. The sleeves 6 and insert rods 7 are fitted with the same spring 8. A connecting plate 9 is fixedly connected to one side of the movable plate 5. Two pins 10 are fixedly connected to the connecting plate 9 on the side away from the movable plate 5. The two pins 10 are fitted with the same limiting plate 11. Two slots 12 adapted to the pins 10 are opened on the limiting plate 11. A laser rangefinder 13 is fixedly connected to the limiting plate 11. A fixing frame 14 is fixedly connected to one side of the installation plate 2. The laser rangefinder 13 is housed within the fixing frame 14. By employing a technique that adjusts the positions of two fixed plates while simultaneously restricting the position of the laser rangefinder, the device can be secured when the fixed plates contact the steel structure. When the slider moves to the vertical surface of the moving plate, the pin can be inserted into the slot, thus restricting the position of the laser rangefinder and allowing it to be installed. This effectively solves the problem mentioned in the background art that most existing measurement and positioning devices for curved roof steel structures generally use laser rangefinders to measure the distance between two steel structures. Typically, the laser rangefinder is handheld by the operator, which can be affected by the operator's stability, potentially leading to inaccurate measurement results. This invention effectively fixes the position of the laser rangefinder, avoiding shaking or displacement during manual operation, improving the stability of measurement and positioning, significantly improving measurement accuracy, and facilitating the disassembly and maintenance of the laser rangefinder.

[0016] In this embodiment, a positioning block 15 is fixedly connected to one side of the laser rangefinder 13, and a positioning groove 16 adapted to the positioning block 15 is provided on the fixing frame 14. The position of the laser rangefinder 13 is positioned by inserting the positioning block 15 into the positioning groove 16.

[0017] In this embodiment, the mounting plate 2 is provided with a mounting groove 17, and the movable plate 5, sleeve 6, plug rod 7, and spring 8 are all disposed in the mounting groove 17. The movable plate 5 and the connecting plate 9 are slidably connected to the mounting plate 2.

[0018] In this embodiment, a bidirectional lead screw 19 is threaded through the mounting plate 2. The bidirectional lead screw 19 is rotatably connected to the mounting plate 2. Both ends of the bidirectional lead screw 19 are fitted with lead screw nuts 18, which are adapted to the bidirectional lead screw 19. The lead screw nuts 18 are fixedly connected to the slider 3. Rotating the bidirectional lead screw 19 causes the lead screw nuts 18 to move, thereby adjusting the position of the slider 3.

[0019] In this embodiment, a worm gear 20 is fixedly connected to the top of the bidirectional lead screw 19. A worm 21 is provided on one side of the worm gear 20 for use with it. A knob 23 is fixedly connected to one side of the worm 21. Rotating the knob 23 causes the worm 21 to rotate, which in turn drives the worm gear 20 to rotate. The self-locking function of the worm 21 and the worm gear 20 ensures the stability of the position of the bidirectional lead screw 19.

[0020] In this embodiment, both ends of the worm gear 21 are fitted with fixed seats 22, the fixed seats 22 are fixedly connected to the mounting plate 2, and the worm gear 21 is rotatably connected to the fixed seats 22.

[0021] Working principle: In use, after fixing the first steel structure 1, place the two fixing plates 4 on both sides of the steel structure 1. Rotate the knob 23, which will drive the worm gear 21 to rotate. The worm gear 21 will drive the worm wheel 20 to rotate, which in turn will drive the double-acting screw 19 to rotate. The double-acting screw 19 will then drive the screw nut 18 to move, which will in turn drive the slider 3 to move along the mounting plate 2. The movement of the slider 3 will then drive the fixing plates 4 to move closer together until they contact the steel structure 1, thus fixing the device onto the steel structure 1. Before adjustment, the laser... The rangefinder 13 is inserted into the fixing bracket 14. The positioning block 15 and positioning groove 16 work together to position the laser rangefinder 13, ensuring its stability. During the movement of the slider 3, it contacts the inclined surface of the moving plate 5. If the slider 3 continues to move, it will press against the moving plate 5, causing it to move laterally. The movement of the moving plate 5 will drive the sleeve 6 to move along the insertion rod 7, ensuring stability during its movement. Simultaneously, the moving plate 5 will compress the spring 8, causing it to contract. The movement of the moving plate 5 will also drive the connecting plate 9 to move, which in turn will move the pin 1. 0. When slider 3 moves to the vertical surface of moving plate 5, pin 10 will insert into slot 12, thus fixing the position of laser rangefinder 13. Laser rangefinder 13 is then installed. For subsequent maintenance without disassembling laser rangefinder 13, simply keep slider 3 on the vertical side of moving plate 5. Activating laser rangefinder 13 causes its laser emitter to emit a laser signal, which is then projected onto another steel structure 1. The reflected laser signal is received by the receiver on laser rangefinder 13 and processed by its built-in processor. The detected distance data is displayed on the screen of the laser rangefinder 13. Adjust the position of the other steel structure 1 until it is in a suitable position. When the laser rangefinder 13 needs to be removed for maintenance, keep the two sliders 3 moving away from each other until they are at their farthest points. The retracted spring 8 will then extend, allowing the moving plate 5 to move laterally in the opposite direction. This will remove the pin 10 from the slot 12, thus releasing the restriction on the laser rangefinder 13. The laser rangefinder 13 can then be removed from the mounting bracket 14 for maintenance, such as battery replacement and cleaning.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
