Description

Technical Field

[0001] This application relates to building construction, and in particular to a module hoisting strain testing device. Background Technology

[0002] Modular hoisting strain testing equipment is a testing device that uses sensors to monitor the strain and stress data of hoisting components such as modular buildings and heavy equipment in real time, in order to ensure hoisting safety, improve installation accuracy, optimize construction efficiency, and adapt to complex working conditions.

[0003] A search revealed Chinese Patent Publication No. CN221706793U, which discloses an integrated stress acquisition device for hoisting equipment. The device includes a protective housing, within which a circuit integrated board is installed. The circuit integrated board is electrically connected to strain gauges located at the bottom of the protective housing via leads. The strain gauges are tightly fitted to the surface of the hoisting equipment, and a protective colloid is applied to the upper surface of the strain gauges. The circuit integrated board includes a signal acquisition module, a signal processing module, a signal storage module, and a signal transmission module. This invention features a simple structure, small size, ease of use, and stable and reliable performance. After installation, it can monitor the strain of the hoisting equipment at any time, and then store the acquired and processed data for future optimization design of the hoisting equipment.

[0004] The aforementioned patent specification mentions that the "integrated stress acquisition device has a simple structure, small size, is easy to use, and has stable and reliable performance. After installation, it can monitor the strain of the hoisting equipment at any time, and then store the collected and processed data to facilitate the subsequent optimization design of the hoisting equipment." While the aforementioned patent can monitor strain, it cannot adjust the direction of the detector according to different angles. Therefore, a modular hoisting strain detection device is proposed to solve this problem. Utility Model Content

[0005] The purpose of this application is to provide a modular hoisting strain detection device, which aims to improve the problem of not being able to adjust the angle of the detector according to the on-site conditions.

[0006] The present application provides a modular hoisting strain testing device with the following technical solution: a modular hoisting strain testing device includes a hoisting plate, a plurality of connecting mechanisms are fixedly connected to the top of the hoisting plate, angle adjustment mechanisms are fixedly connected to both sides of the hoisting plate, and a lifting mechanism is fixedly connected to the bottom of the hoisting plate; The angle adjustment mechanism includes a cylinder, the outer side of which is fixedly connected to the inside of the lifting plate. A rack plate is fixedly connected to the drive end of the cylinder. A frame is slidably connected to both sides of the rack plate. A gear is rotatably connected to the inner side of the frame. A detection component is fixedly connected to the bottom of the gear. Through the above technical solution: when the angle adjustment mechanism is running, after the cylinder is started, the drive end extends and retracts, causing the rack plate fixed to it to slide within the frame. The sliding connection between the rack plate and the frame on both sides ensures its smooth movement. During the sliding process, the rack plate meshes with the gear, causing the gear to rotate inside the frame. Since the detection component is fixed at the bottom of the gear, the rotation of the gear causes the detection component to rotate synchronously, realizing the angle adjustment of the detection component. By controlling the extension and retraction direction and distance of the cylinder drive end, the angle of the detection component can be precisely adjusted, allowing it to flexibly adjust the detection direction according to the hoisting requirements and meet the working requirements for detection at different directional distances.

[0007] Preferably, the detection component includes a flip plate, the top of which is fixedly connected to the bottom of the gear, and the bottom of which is fixedly connected to two distance detection modules; By adopting the above technical solution, when the gear rotates, it drives the fixed tilting plate to rotate synchronously. Since there are two distance detection modules fixed at the bottom of the tilting plate, the rotation of the tilting plate causes the detection modules to change their orientation. Thus, the detection direction can be flexibly adjusted to detect distances in different directions, ensuring that the modular building maintains a safe distance from surrounding objects during hoisting.

[0008] Preferably, the connecting mechanism includes a fixed column, the bottom of which is fixedly connected to the top of the lifting plate, a sliding column is slidably connected inside the fixed column, a bolt is threaded inside the sliding column, a connecting block is slidably connected inside the fixed column, and a fixed block is fixedly connected to the top of the connecting block; By adopting the above technical solution, during connection, the bolt inside the sliding column is unscrewed, the sliding column is pulled outward, causing the connecting block to slide into the fixed column. After resetting the sliding column, the connecting block is secured using the slot at the top of the fixed column. Then, the bolt is screwed into the sliding column and the fixed column to complete the connection. During disassembly, the bolt is unscrewed, and the sliding column moves the connecting block out of the fixed column, separating the connection structure. Through the cooperation of bolts, sliding columns, and fixed columns, rapid connection and disassembly of the lifting plate and parts can be achieved, ensuring flexible and efficient lifting operations.

[0009] Preferably, the lifting mechanism includes multiple triangular plates, the tops of which are fixedly connected to the bottom of the lifting plate, and two lifting blocks are fixedly connected to the bottom of the lifting plate; By adopting the above technical solution, when the lifting mechanism is working, multiple triangular plates are connected to the bottom of the lifting plate. The triangular structure enhances stability and distributes the force during lifting. Two lifting blocks serve as the main load-bearing points, used to connect lifting tools such as slings. In conjunction with the triangular plates, they evenly transfer the weight of the modular building to the lifting equipment, ensuring a smooth and safe lifting process.

[0010] Preferably, sliding strips are fixedly connected to both sides of the rack plate, and the outer side of the sliding strips is slidably connected to the inside of the frame; By adopting the above technical solution, when the cylinder drives the rack plate to move, the sliding bars on both sides slide synchronously within the frame, providing guidance and support for the rack plate. The sliding cooperation between the sliding bars and the frame ensures that the rack plate moves smoothly along a fixed trajectory, avoiding deviation and shaking, making the meshing transmission between the rack plate and the gear more precise, and ensuring the stability and reliability of the flip angle of the detection component.

[0011] Preferably, the bottom of the rack plate is meshed with the outside of the gear, and the top of the flip plate is slidably connected to the outside of the frame; By adopting the above technical solution, when the rack plate moves under the drive of the cylinder, its bottom meshes with the gear, causing the gear to rotate. When the gear rotates, the flip plate fixed at its bottom moves accordingly. The top of the flip plate slides on the outside of the frame, which not only restricts the movement trajectory of the flip plate and ensures its smooth flipping, but also provides support for the detection component to adjust the angle, ensuring accurate switching of the distance detection direction.

[0012] Preferably, a limiting post is fixedly connected inside the fixing post, and the outer thread of the bolt is connected inside the limiting post; By adopting the above technical solution, the limiting column inside the fixed column provides a threaded connection point for the bolt. When the sliding column is reset, the bolt is screwed in, and the bolt passes through the sliding column and the limiting column in sequence. The two are fastened by the thread engagement. This structure restricts the movement of the sliding column, ensures the stability of the connection mechanism, ensures that the components will not loosen during hoisting, and improves the overall safety and reliability.

[0013] Preferably, the outer side of the connecting block is slidably connected to the inside of the sliding post, and the outer side of the connecting block is slidably connected to the inside of the limiting post; By adopting the above technical solution, when the sliding column is pulled, the connecting block slides inside it and slides into the fixed column. The limiting column further guides and constrains the connecting block. After the sliding column is reset, the connecting block and the limiting column cooperate and are fixed in position through the slot. After the bolt is screwed in, the connecting block is clamped between the sliding column and the limiting column, ensuring that the three are tightly connected, forming a stable structure and ensuring hoisting safety.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the starting cylinder drives the rack plate, the rack plate drives the gear, the gear drives the flip plate, and the flip plate drives the distance detection module, thereby achieving the effect of adjusting the angle of the distance detection module. It can not only detect the height but also the distance in front and behind. With its highly integrated multi-dimensional detection function, the fixed transmission ratio ensures accurate angle adjustment. Combined with the rapid response of the cylinder and the anti-interference characteristics of the mechanical structure, the detection efficiency and reliability are significantly improved. Its compact modular design takes into account space adaptability and convenient maintenance, and the safety redundancy mechanism effectively avoids the risk of collision.

[0015] 2. In this utility model, by using a fixed column in conjunction with a sliding column and a limiting column, the sliding column in conjunction with bolts and connecting blocks, and the connecting blocks in conjunction with a fixed block, the steel cable can be replaced even without tools. Its advantages are that no tools such as wrenches are required during operation; the steel cable can be disassembled and assembled simply by manually turning the bolts and sliding parts. A single person can complete the maintenance in a short time. At the same time, the standardized interface can be adapted to steel cables of different specifications, improving the equipment's versatility. Attached Figure Description

Detailed Implementation

[0017] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0018] Example: A modular hoisting strain testing device, referring to... Figures 1 to 3The system includes a lifting plate 1, with multiple connecting mechanisms 2 fixedly connected to the top of the lifting plate 1. These connecting mechanisms 2 can be quickly and securely connected to modular buildings or lifting equipment. Angle adjustment mechanisms 3 are fixedly connected to both sides of the lifting plate 1. These mechanisms can flexibly adjust the direction of the components according to the lifting requirements, and achieve accurate detection of height and front-to-back distance during the lifting process to avoid collisions or positional deviations. A lifting mechanism 4 is fixedly connected to the bottom of the lifting plate 1. The lifting mechanism 4 effectively distributes the lifting weight through the coordinated action of multiple components. Specifically, the connecting mechanism 2 at the top of the hoisting plate 1 can quickly and securely connect modular buildings or hoisting equipment, ensuring that the components do not loosen during hoisting. The angle adjustment mechanisms 3 on both sides can flexibly adjust the direction of the components, accurately detect the hoisting height and front-to-back distance, and avoid collisions. The bottom hoisting mechanism 4 distributes the weight through the triangular plate 41 and the hoisting block 42, enhancing the load-bearing capacity and stability, ensuring the smooth hoisting of modular buildings, and improving operational safety.

[0019] The angle adjustment mechanism 3 includes a cylinder 31, the outer side of which is fixedly connected to the inside of the lifting plate 1. The cylinder 31 can provide a stable driving force and provide reliable power support for angle adjustment. The drive end of the cylinder 31 is fixedly connected to a rack plate 32. When the cylinder 31 is started, the extension and retraction of the drive end drives the rack plate 32 to move synchronously. Sliding strips 36 are fixedly connected to both sides of the rack plate 32. The sliding strips 36 are tightly engaged with the rack plate 32. When the rack plate 32 moves, the sliding strips 36 can enhance its stability. Frames 35 are slidably connected to both sides of the rack plate 32. The frames 35 provide a precise sliding track for the rack plate 32, so that the rack plate 32 can only move linearly within the range limited by the frames 35. The outer side of the sliding bar 36 is slidably connected to the inside of the frame 35. This sliding connection method further optimizes the movement trajectory of the rack plate 32, reduces frictional resistance, makes the rack plate 32 slide more smoothly in the frame 35, and improves the efficiency of angle adjustment. The inner side of the frame 35 is rotatably connected to the gear 33. The gear 33 can rotate flexibly under the support of the frame 35 and meshes with the rack plate 32 to convert the linear motion of the rack plate 32 into its own rotational motion. The bottom of the rack plate 32 is meshed with the outer side of the gear 33. This meshing relationship ensures efficient power transmission. When the rack plate 32 moves, it can accurately drive the gear 33 to rotate, realizing precise angle adjustment. The bottom of the gear 33 is fixedly connected to the detection component 34. The rotation of the gear 33 directly drives the detection component 34 to rotate synchronously, so that the detection component 34 can adjust the detection direction according to actual needs and realize accurate detection of distances in different directions. Specifically, the cylinder 31 is fixed inside the lifting plate 1 to provide stable driving force for the mechanism. Its driving end drives the rack plate 32 to move linearly along a preset trajectory. The sliding strips 36 on both sides of the rack plate 32 cooperate with the frame 35 to enhance motion stability, reduce frictional resistance, and make sliding smoother. The gear 33 inside the frame 35 meshes with the rack plate 32 to convert linear motion into rotational motion, driving the detection component 34 to rotate, thereby adjusting the detection direction according to the requirements and achieving accurate detection of distances in different directions.

[0020] The detection component 34 includes a tilting plate 341, the top of which is slidably connected to the outside of the frame 35. This connection method restricts the movement trajectory of the tilting plate 341 while allowing it to rotate flexibly, ensuring a stable and non-deviation-free tilting process. The top of the tilting plate 341 is fixedly connected to the bottom of the gear 33, ensuring that the tilting plate 341 can rotate synchronously and accurately when the gear 33 rotates, achieving seamless power transmission. The bottom of the tilting plate 341 is fixedly connected to two distance detection modules 342. As the tilting plate 341 rotates, the distance detection modules 342 can quickly switch detection directions to monitor the height or front-to-back distance of the hoisted object in real time, providing accurate data support for hoisting operations. Specifically, the detection component 34 consists of a flip plate 341 and a distance detection module 342. The top of the flip plate 341 is slidably connected to the outside of the frame 35 to ensure stable flipping, and it is fixed to the bottom of the gear 33 to achieve synchronous rotation. The two distance detection modules 342 fixed at the bottom can flexibly adjust their direction with the flip plate 341 to monitor the height and front-to-back distance of the hoisted object in real time, providing accurate data support for hoisting operations and ensuring operational safety.

[0021] Reference Figure 1 , Figure 2 and Figure 4 The connecting mechanism 2 includes a fixed column 21, with a limiting column 23 fixedly connected inside the fixed column 21. The limiting column 23 provides a stable threaded connection base for the bolt 24, ensuring that the bolt 24 can firmly lock all components after being screwed in, thus enhancing the overall stability of the connecting mechanism 2. The bottom of the fixed column 21 is fixedly connected to the top of the lifting plate 1. This connection method allows the fixed column 21 to reliably transfer the lifting load to the lifting plate 1, ensuring even force distribution during the lifting process and avoiding excessive local stress. The fixed column 21 has a sliding column 22 inside, which can slide flexibly within the fixed column 21, facilitating quick adjustment of the connection position and achieving efficient docking with modular buildings, thereby improving the efficiency of lifting operations. The sliding column 22 has a bolt 24 inside, which can be tightened or loosened by engaging with the thread of the sliding column 22. When tightened, the sliding column 22 can be firmly connected to the fixed column 21, preventing relative movement. The outer thread of bolt 24 is connected to the inside of the limiting column 23. This double thread connection design further enhances the reliability of the connection, enabling bolt 24 to lock the sliding column 22 and the limiting column 23 simultaneously, forming a stable structural whole. The inside of the fixed column 21 is slidably connected to a connecting block 25. The connecting block 25 can slide freely within the fixed column 21. When connected to the modular building, its position can be adjusted according to actual needs to ensure a tight and precise connection. The outer thread of the connecting block 25 is slidably connected to the inside of the limiting column 23. The limiting column 23 provides guidance and support for the connecting block 25, keeping it stable during sliding and preventing swaying or displacement, thus ensuring the stability of the connection. The outer thread of the connecting block 25 is slidably connected to the inside of the sliding column 22. This multi-layer sliding connection structure enables the connecting block 25 to move in tandem with the sliding column 22 to jointly complete the connection and fixing tasks with the modular building. The top of the connecting block 25 is fixedly connected to a fixing block 26. The fixing block 26 is used to connect with the corresponding structure on the modular building, providing a stable point of force and ensuring that the connecting mechanism 2 will not separate from the building during hoisting. Specifically, the bottom of the fixed column 21 is connected to the lifting plate 1 to evenly distribute the load. The internal limiting column 23 provides a stable connection base for the bolt 24. The sliding column 22 can slide flexibly within the fixed column 21. Through the double threaded connection between the bolt 24 and the limiting column 23, it can be tightened or loosened with the fixed column 21, enhancing the reliability of the connection. The connecting block 25 slides within the fixed column 21, the limiting column 23, and the sliding column 22, and its position can be adjusted as needed. It works in coordination with the sliding column 22. The fixed block 26 at its top is connected to the modular building, providing a stable point of force to ensure a tight connection and prevent separation during the hoisting process.

[0022] The lifting mechanism 4 includes multiple triangular plates 41. The triangular plates 41 effectively disperse the stress during the lifting process through the stability of the triangular structure, enhance the structural strength of the bottom of the lifting plate 1, and ensure that it does not deform when bearing heavy loads. The tops of the multiple triangular plates 41 are all fixedly connected to the bottom of the lifting plate 1. Two lifting blocks 42 are fixedly connected to the bottom of the lifting plate 1. The lifting blocks 42 serve as direct force-bearing points and can firmly connect to external lifting equipment, evenly transmitting the lifting force to the lifting plate 1, ensuring the smooth lifting and lowering of the modular building. Specifically, the triangular plate 41, with its stable triangular structure, effectively disperses the lifting stress, significantly enhances the bottom strength of the lifting plate 1, and avoids deformation under heavy load. Its top is fixed to the bottom of the lifting plate 1, forming a stable support. The lifting block 42, as a direct load-bearing component, can be firmly connected to external lifting equipment, and evenly transmits the lifting force to the lifting plate 1, ensuring that the modular building remains stable during lifting and lowering, and ensuring safe and efficient lifting operations.

[0023] Working principle: When workers need to lift the modular building, they can fix the modular building using the triangular plate 41 and the lifting block 42. When connecting the top, the handle connected to the outside of the bolt 24 can be rotated to straighten the bolt 24 from the inside of the sliding column 22. Then, the sliding column 22 can be pulled outward to make the connecting block 25 slide into the inside of the fixed column 21. Then, the sliding column 22 can be placed back in its original position. The connecting block 25 is fixed by the retaining column 23 and the slot at the top of the sliding column 22. Then, the bolt 24 is rotated into the inside of the sliding column 22 and the retaining column 23. At this time, the lifting steel cable can be connected, and the lifting connection is achieved by the hook connected to the other end of the steel cable.

[0024] When lifting the modular building, the distance detection modules 342 connected to both sides of the lifting plate 1 can detect its height and front-to-back distance. When the modular building is lifted, the cylinder 31 can be activated to pull the rack plate 32 inward, causing the gear 33 at the bottom of the rack plate 32 to rotate inward as well. The bottom of the gear 33 is fixed with a flip plate 341. At this time, the flip plate 341 will be driven by the gear 33, thereby flipping the distance detection module 342 over, thus realizing the detection of the front-to-back distance. When the modular building needs to be lowered, the cylinder 31 can be pushed forward, causing the rack plate 32 to rotate the gear 33 back to its original position, so that the distance detection module 342 faces the bottom, thereby achieving the effect of distance control of the lowering height.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
