Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to an auxiliary device for measuring building height. Background Technology
[0002] Building measurement height positioning auxiliary devices are professional tools used in building engineering to assist in measuring vertical height and ensure the installation accuracy of building components. Their core function is to provide a stable mounting platform for level instruments or total stations by fixing measurement benchmarks and transmitting height data during the building construction process, thus ensuring the accuracy of measurement results.
[0003] Currently, building height positioning auxiliary devices on the market adopt fixed or single clamping structures. Although they achieve basic positioning functions through bolt fixing or magnetic attraction, avoiding errors from manual hand measurement, in terms of installation adaptability, existing devices are directly fixed to the building base through rigid brackets and rely on preset installation holes or magnetic surfaces to contact the base. They can only be installed on flat and regular surfaces and cannot meet the positioning needs of irregular structures or uneven surfaces in building construction sites.
[0004] When faced with objects of different diameters, it is impossible to achieve a tight fit through flexible adjustment, resulting in an unstable measurement reference. Gaps are easily generated between the rigid support and the base, causing the device to tilt or shake, which in turn affects the measurement accuracy and fails to meet the positioning requirements of complex working conditions in building construction.

The cylindrical tube is engaged between the two rubber pads.
[0010] As a further description of the above technical solution:

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0033] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a building height positioning auxiliary device, including a wall 1, a cylindrical tube 5 and two hollow steel pipes 2. A distance adjustment mechanism 3 is provided on the outside of the two hollow steel pipes 2, and a clamping mechanism 4 is provided at the bottom of the distance adjustment mechanism 3. The distance adjustment mechanism 3 is used to adjust the distance of the clamping mechanism 4, and the clamping mechanism 4 is used to adapt to different clamping objects.
[0034] The distance adjustment mechanism 3 includes two fixed plates 31, which are respectively fixedly connected to the rear outer side of two hollow steel pipes 2. Each hollow steel pipe 2 has a threaded groove 32 on its front outer side. Two threaded sleeves 33 are threadedly connected to the outer side of each threaded groove 32. A connecting rod 34 is fixedly connected between the two threaded sleeves 33 on the left and the two threaded sleeves 33 on the right. A handwheel 35 is fixedly connected to the outer side of each of the two front threaded sleeves 33. A sliding assembly 36 is provided on the outer side of each of the threaded sleeves 33. 36 includes multiple limiting grooves 361, which are respectively opened on the outside of multiple threaded sleeves 33. Multiple balls 362 are rotatably connected at equal intervals on the inner side of the multiple limiting grooves 361. The inner side of multiple rotating wheels 37 is rotatably connected to the outside of the multiple balls 362. The inside of the multiple threaded sleeves 33 is rotatably connected to the rotating wheels 37 through the sliding assembly 36. Vertical limiting plates 38 are fixedly connected to the upper middle part of the front side of the two fixed plates 31. The two vertical limiting plates 38 are perpendicular to the two fixed plates 31 respectively.
[0035] Specifically, the distance adjustment mechanism 3 uses two fixed plates 31 as basic support components, which are fixedly connected to the outer rear sides of the two hollow steel pipes 2, forming a symmetrical and stable installation structure. Each of the outer front sides of the two hollow steel pipes 2 has a threaded groove 32, which extends axially along the hollow steel pipe 2. Its thread specification matches the inner thread of the threaded sleeve 33, forming a threaded transmission system. The four threaded sleeves 33 are threadedly connected to two of the threaded grooves 32, with the two threaded sleeves 33 on the left and the two threaded sleeves 33 on the right being fixedly connected by a connecting rod 34, making the two threaded sleeves 33 on the same side form a rigid whole, ensuring synchronous movement on both sides during adjustment.
[0036] The handwheels 35, which are externally fixed to the two threaded sleeves 33 on the front side, provide an interface for the operator to apply force. When the handwheels 35 are rotated, the threaded sleeves 33 move along the axial direction of the threaded grooves 32 due to the thread transmission principle. The two threaded sleeves 33 on the same side move synchronously, thereby adjusting the distance of the clamping mechanism 4.
[0037] The sliding assembly 36 externally provided on the threaded sleeve 33 further optimizes motion performance. Multiple limiting grooves 361 are formed on the outer circumferential surface of the threaded sleeve 33, extending axially. Equidistantly distributed balls 362 on their inner sides are rotatably connected within the limiting grooves 361 via a rotating shaft. The inner side of the rotating wheel 37 is rotatably connected to the outer side of the balls 362, forming a rolling friction pair. When the threaded sleeve 33 rotates, the balls 362 roll within the rotating wheel 37, converting traditional sliding friction into rolling friction, significantly reducing motion resistance and minimizing wear between the threaded sleeve 33 and other components. Furthermore, the limiting grooves 361 circumferentially limit the balls 362, preventing them from disengaging and ensuring a stable connection between the rotating wheel 37 and the threaded sleeve 33.
[0038] A vertical limiting plate 38 is fixedly connected to the upper middle part of the front side of the two fixed plates 31, and is arranged perpendicular to the fixed plates 31 to form a vertical limiting structure. During the movement of the threaded sleeve 33, the vertical limiting plate 38 restricts its displacement in the vertical direction, ensuring that the threaded sleeve 33 only translates along the axial direction of the hollow steel pipe 2, avoiding adjustment errors caused by tilting or shaking. The vertical limiting plate 38 and the fixed plate 31 are connected by welding or bolts, and the connection strength is sufficient to withstand the lateral force during the adjustment process, ensuring the stability and accuracy of the mechanism's movement.
[0039] In practical applications, when the distance of the clamping mechanism 4 needs to be adjusted, the operator rotates the handwheel 35, causing the threaded sleeve 33 to move on the threaded groove 32, and the connecting rod 34 enables synchronous adjustment on both sides. The ball bearing 362 of the sliding component 36 cooperates with the rotating wheel 37 to reduce motion friction and make the adjustment process smoother; the vertical limiting plate 38 limits the mechanism in the vertical direction to ensure adjustment accuracy. Through the coordinated operation of the above components, the distance adjustment mechanism 3 can achieve precise control of the distance of the clamping mechanism 4, meeting the needs of adjusting the spacing of measuring tools in different scenarios in building surveying.
[0040] Through the threaded transmission, linkage structure, sliding friction reduction and vertical limit design of the distance adjustment mechanism 3, the distance of the clamping mechanism 4 can be quickly and accurately adjusted in building measurement scenarios, providing reliable support for the stable installation and accurate positioning of measuring tools.
[0041] Reference Figure 1 , Figure 3 and Figure 4 The clamping mechanism 4 includes multiple guide rods 41, which are fixedly connected to the bottom of multiple rotating wheels 37. The bottom ends of the multiple guide rods 41 on the left and the multiple guide rods 41 on the right are fixedly connected to L-shaped moving plates 42. The front side of the two fixed plates 31 and the rear side of the two L-shaped moving plates 42 are provided with arc-shaped grooves 43. Rubber pads 44 are fixedly connected inside the multiple arc-shaped grooves 43. The cylindrical tube 5 is engaged between the two rubber pads 44.
[0042] Specifically, multiple guide rods 41 are rigid members, fixedly connected to the bottom of multiple rotating wheels 37. Their tops are bolted to the bottom of the rotating wheels 37, and their bottoms are welded to the L-shaped moving plate 42, forming a force transmission path. When the threaded sleeve 33 in the distance adjustment mechanism 3 drives the rotating wheels 37 to move axially along the hollow steel pipe 2, the guide rods 41 move synchronously with the rotating wheels 37, transmitting the displacement to the L-shaped moving plate 42. The length of the guide rods 41 matches the installation height of the rotating wheels 37, ensuring the horizontal movement accuracy of the L-shaped moving plate 42.
[0043] The bottom ends of multiple guide rods 41 on the left and multiple guide rods 41 on the right are all fixedly connected to L-shaped moving plates 42. The L-shaped moving plate 42 consists of a horizontal section and a vertical section. The horizontal section is fixed to the guide rods 41, and the vertical section faces the fixed plate 31, with an arc-shaped groove 43 on its rear side. The front sides of the two fixed plates 31 also have arc-shaped grooves 43, and the positions of the arc-shaped grooves 43 on the fixed plates 31 and the L-shaped moving plate 42 are symmetrical, forming a clamping structure for the cylindrical tube 5. The angle between the horizontal and vertical sections of the L-shaped moving plate 42 is 90° to ensure sufficient structural strength to withstand the clamping force.
[0044] The arc surface curvature of the arc groove 43 matches the outer circumference of the cylindrical tube 5, and its opening direction faces the cylindrical tube 5. Rubber pads 44 are fixedly connected inside the multiple arc grooves 43. The rubber pads 44 are made of neoprene rubber, 5mm thick, with a roughened surface to increase friction with the cylindrical tube 5. When the L-shaped moving plate 42 approaches the fixed plate 31 under the influence of the guide rod 41, the rubber pads 44 on both sides contact and compress the outer surface of the cylindrical tube 5. The elastic deformation of the rubber pads 44 creates a clamping force, fixing the cylindrical tube 5 between the two rubber pads 44.
[0045] The rubber pad 44 is bonded and fixed to the arc-shaped groove 43 with adhesive, and its arc-shaped surface fits tightly with the groove surface of the arc-shaped groove 43. The neoprene rubber has a Shore hardness of 60A, exhibiting good wear resistance and weather resistance, allowing for long-term use in outdoor environments used in construction surveying. When the diameter of the cylindrical tube 5 changes, the elastic deformation of the rubber pad 44 can adapt to different dimensions, ensuring clamping stability and guaranteeing that cylindrical tubes 5 of different specifications can be reliably clamped.
[0046] Driven by the distance adjustment mechanism 3, the L-shaped moving plate 42 moves horizontally, causing the arc-shaped groove 43 and the rubber pad 44 to move closer to or further away from the fixed plate 31. Once the rubber pad 44 contacts the cylindrical tube 5, further adjustment of the distance adjustment mechanism 3 will cause the rubber pad 44 to elastically compress until the clamping force reaches the design requirements. At this point, the cylindrical tube 5 is stably fixed, and its axis is perpendicular to the axis of the hollow steel pipe 2, meeting the installation accuracy requirements for height positioning in building surveying.
[0047] Through the coordinated action of the guide rod 41 transmitting displacement, the L-shaped moving plate 42 driving the arc groove 43 to move, and the rubber pad 44 elastically clamping, the cylindrical tubes 5 of different diameters are stably clamped in the construction measurement scenario, and the installation and positioning accuracy of the measuring tools is ensured.
[0048] Reference Figure 1 , Figure 2 and Figure 5 The rear ends of the two hollow steel pipes 2 are fixedly connected to the mounting plate 6. The bottom of the mounting plate 6 is fixedly connected to the electric winding wheel 7. The electric winding wheel 7 is equipped with a nylon rope 8. The bottom end of the nylon rope 8 is fixedly connected to the tension sensor 9. The bottom end of the tension sensor 9 is fixedly connected to the hook 10. The tension sensor 9 is electrically connected to the electric winding wheel 7. The hook 10 is rotatably connected to the outside of the hook 10. The inner side of the anti-detachment baffle 11 adopts an arc design. The top of the mounting plate 6 is fixedly connected to the mounting bracket 12. The mounting bracket 12 is fixedly connected to multiple levels 13. The multiple levels 13 adopt a multi-directional design.
[0049] Specifically, mounting plates 6 are fixedly connected to the rear ends of both hollow steel pipes 2. The mounting plates 6 are rectangular metal plates, fixed to the rear ends of the hollow steel pipes 2 with bolts, providing a mounting base for the electric winding wheel 7 and the mounting frame 12. The bottom of the mounting plate 6 is fixedly connected to the electric winding wheel 7, which contains a nylon rope 8 wound and stored on a reel. The bottom end of the nylon rope 8 is connected to a tension sensor 9 and a hook 10. The tension sensor 9 is electrically connected to the electric winding wheel 7, enabling real-time monitoring of the tension data of the nylon rope 8 and feedback to the control system of the electric winding wheel 7.
[0050] The hook 10 is externally rotatably connected to an anti-detachment baffle 11. The anti-detachment baffle 11 is rotatably connected to the top of the hook 10 via a pivot. Its inner side adopts an arc design to match the arc of the hook 10 opening. When the hook 10 is loaded with measuring tools or heavy objects, the anti-detachment baffle 11 can rotate around the pivot and cover the opening of the hook 10 to prevent the loaded object from falling off. The top of the mounting plate 6 is fixedly connected to a mounting bracket 12. The mounting bracket 12 is a frame structure, and multiple levels 13 are fixed inside. The levels 13 adopt a multi-directional design and can simultaneously monitor the horizontal status of the device in the X, Y, and Z axis directions.
[0051] When the electric winding reel 7 is powered on, the reel can rotate in both directions to wind and unwind the nylon rope 8, driving the hook 10 to rise and fall. The tension sensor 9 detects the tension value of the nylon rope 8 in real time. When the tension exceeds the set threshold, it sends a signal to the electric winding reel 7, which automatically stops winding the rope to avoid overload damage. The arc-shaped inner side of the anti-detachment baffle 11 forms a closed structure with the opening of the hook 10. When an object is hung, the weight of the object makes the anti-detachment baffle 11 stick tightly to the hook 10 to prevent the object from falling off.
[0052] The multi-directional level 13 detects the horizontal state of the device using a bubble or electronic sensor. When the device tilts, the pointer or digital display of the level 13 shows the offset. The operator can adjust the device position based on the feedback from the level 13 to ensure the accuracy of the measurement reference. The level 13 is fixed to the mounting bracket 12 by a slot, facilitating disassembly and calibration.
[0053] Working principle: The distance adjustment mechanism 3 is symmetrically fixed to the rear side of the hollow steel pipe 2, supported by two fixed plates 31. The threaded groove 32 on the front side of the hollow steel pipe 2 and four threaded sleeves 33 constitute a threaded transmission system. When the operator rotates the handwheel 35 on the front threaded sleeve 33, the threaded sleeve 33 moves axially along the hollow steel pipe 2 due to the threaded transmission principle. Since the two threaded sleeves 33 on the same side are rigidly connected by the connecting rod 34, rotating one handwheel 35 can drive the two threaded sleeves 33 on the same side to move synchronously.
[0054] The sliding assembly 36 on the outside of the threaded sleeve 33 further optimizes the adjustment performance. The ball 362 within the limiting groove 361 forms a rolling friction pair with the rotating wheel 37. When the threaded sleeve 33 moves, the ball 362 rolls inside the rotating wheel 37, converting sliding friction into rolling friction and reducing motion resistance. Simultaneously, the limiting groove 361 provides circumferential restraint to the ball 362, preventing it from disengaging and ensuring a stable connection between the rotating wheel 37 and the threaded sleeve 33. The vertical limiting plate 38 is vertically fixed to the fixed plate 31, limiting the vertical displacement of the threaded sleeve 33 during movement, ensuring only axial translation and improving adjustment accuracy.
[0055] The clamping mechanism 4 is linked to the distance adjustment mechanism 3 via the guide rod 41. The top of the guide rod 41 is bolted to the rotating wheel 37, and the bottom is welded to the L-shaped moving plate 42, forming a stable force transmission path. When the distance adjustment mechanism 3 drives the rotating wheel 37 to move axially, the guide rod 41 drives the L-shaped moving plate 42 to move horizontally in sync.
[0056] Both the rear side of the vertical section of the L-shaped moving plate 42 and the front side of the fixed plate 31 are provided with arc-shaped grooves 43, and neoprene rubber pads 44 are pasted in the grooves with roughened surfaces. When the L-shaped moving plate 42 approaches the fixed plate 31 under the action of the guide rod 41, the rubber pads 44 on both sides contact and compress with the outer surface of the cylindrical tube 5, and the elastic deformation of the rubber pads 44 generates clamping force. As the distance adjustment mechanism 3 is continuously adjusted, the compression of the rubber pads 44 increases, the clamping force increases, until the cylindrical tube 5 is stably fixed. The elastic deformation of the rubber pads 44 can adapt to cylindrical tubes 5 of different diameters to ensure clamping stability.
[0057] Mounting plate 6 is fixed to the rear end of hollow steel pipe 2, providing support for electric winding wheel 7 and mounting frame 12. The nylon rope 8 inside electric winding wheel 7 is wound around a spool at one end, and the other end is connected in sequence to tension sensor 9 and hook 10.
[0058] When the electric winding reel 7 is powered on, the reel rotates in both directions to wind and unwind the nylon rope 8, which in turn raises and lowers the hook 10. The tension sensor 9 monitors the tension of the nylon rope 8 in real time and feeds the data back to the control system of the electric winding reel 7. When the tension exceeds a set threshold, the tension sensor 9 sends a signal, and the electric winding reel 7 automatically stops to avoid overload. The anti-detachment baffle 11 on the outside of the hook 10 is rotatably connected via a shaft, and its arc-shaped inner side matches the opening of the hook 10. When an object is hung, the object's weight causes the anti-detachment baffle 11 to rotate and cover the opening, forming a closed structure to prevent the object from falling off.
[0059] The mounting bracket 12 is fixed to the top of the mounting plate 6. The internal multi-directional level 13 adopts a bubble-type or electronic sensing design, which can simultaneously monitor the horizontal status of the device in the X, Y, and Z axis directions.
[0060] When the device is tilted, the bubble in the level 13 shifts, and the internal electronic sensor outputs a shift signal. The operator adjusts the device position based on the feedback from the level 13. The level 13 is fixed to the mounting bracket 12 via a slot, facilitating disassembly and calibration and ensuring the accuracy of the measurement reference.
[0061] Before conducting architectural surveying, the device is first installed at a fixed location such as wall 1, and its level is calibrated using a level 13. According to the measurement requirements, the handwheel 35 of the distance adjustment mechanism 3 is rotated to adjust the spacing of the clamping mechanism 4. Then, the cylindrical tube 5 is placed in the middle of the clamping mechanism 4, and further adjustments are made to ensure the rubber pad 44 clamps the cylindrical tube 5 securely.
[0062] To attach measuring tools, start the electric winding wheel 7 to lower the nylon rope 8, hang the tool on the hook 10, and lock it using the anti-detachment baffle 11. Start the electric winding wheel 7 again to raise the tool to the designated height. During the process, the tension sensor 9 monitors the tension in real time to ensure safety.
[0063] 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.
