Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction equipment technology, and in particular to a tension sensor for tool-type external protective frames. Background Technology
[0002] With the acceleration of urbanization, high-rise and super high-rise buildings are becoming increasingly common. External protective frames have become an indispensable safety protection equipment in building construction due to their convenient installation, high turnover rate, and strong adaptability. External protective frames are usually connected to the main structure of the building through embedded parts or bolts. The reliability of their connection is directly related to the safety of construction workers and the stability of the frame.
[0003] However, in actual construction, the stress situation of external protective frames is complex and variable due to factors such as the self-weight of the frame, wind load, and dynamic construction load. If the tension is unevenly distributed or there is local overload, it may lead to frame deformation, failure of connection nodes, or even safety accidents.
[0004] Therefore, a tension sensor for a tool-type external protective frame is proposed to solve the aforementioned problems. Utility Model Content
[0005] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide a tension sensor for a tool-type external protective frame.
[0006] The technical solution of this utility model is as follows: a tension sensor for a tool-type external protective frame, including a protective frame, a tension sensor body installed inside the protective frame, a hook fixedly connected to the bottom of the tension sensor body, several audible and visual alarms fixedly installed on the outside of the protective frame, several buttons provided on one side of the tension sensor body, a controller fixedly installed on the rear side of the protective frame, and an anti-detachment component provided on the outside of the hook.
[0007] By adopting the above technical solution, when the actual tension detected by the tension sensor exceeds the preset value, the controller will control the audible and visual alarm to sound an alarm, thereby reminding the staff to deal with it in time. This enables the monitoring of the tension at each lifting point when the finished frame is hoisted.
[0008] In a preferred embodiment, the anti-detachment component includes a rotating shaft fixedly connected to the inner wall of the hook, with torsion springs sleeved at both ends of the outer side of the rotating shaft, and an anti-detachment component provided inside the hook, which is rotatably mounted on the outer side of the rotating shaft by the torsion springs.
[0009] By adopting the above technical solution, the reaction force of the torsion spring can push the anti-detachment component to reset, so that one end of the anti-detachment component abuts against the inner wall of the hook, thereby preventing the hook from accidentally loosening or slipping.
[0010] In a preferred embodiment, a limiting sleeve is fixedly connected to the top of the protective frame, a fixing post is slidably installed inside the limiting sleeve, and a hanging lug is fixedly connected to the top of the fixing post.
[0011] By adopting the above technical solution, it is convenient to hoist the external protective frame.
[0012] In a preferred embodiment, the limiting sleeve is provided with a limiting component inside, the limiting component including a limiting groove formed inside the limiting sleeve, a limiting member fixedly connected to the outer periphery of the fixing post, and the limiting member being slidably connected to the inner wall of the limiting groove.
[0013] By adopting the above technical solution, the synergistic cooperation of the limiting groove and the limiting component can play an important limiting role for the fixed column and the hanging lug, making the connection more stable.
[0014] In a preferred embodiment, an LCD screen is fixedly mounted on the outside of the tension sensor body and on the side of the button.
[0015] By adopting the above technical solution, the tensile force value can be displayed on the LCD screen, making it convenient for staff to view.
[0016] In a preferred embodiment, a battery pack is built inside the protective frame and located behind the tension sensor body. The battery pack provides power to the controller, the audible and visual alarm, the LCD screen, and the tension sensor body.
[0017] By adopting the above technical solutions, the normal operation of the controller, audible and visual alarm, LCD display, and tension sensor body can be ensured.
[0018] In a preferred embodiment, the end of the anti-slip component away from the pivot abuts against the inner wall of the hook.
[0019] By adopting the above technical solutions, connection stability can be improved.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] 1. In this utility model, the hook can be used to hoist and connect the finished frame. Before hoisting, the preset value of the tension sensor body can be set by pressing a button. When the actual tension detected by the tension sensor body exceeds the preset value, the controller will control the audible and visual alarm to sound an alarm, which will help remind the staff to deal with it in time. This allows the tension of each hoisting point to be monitored during the hoisting of the finished frame, so as to avoid the finished frame from deforming due to excessive tension. In addition, a protective frame is set on the tension sensor body to limit the deformation space of the tension sensor body from a mechanical structure, preventing excessive damage to the tension sensor body after exceeding the limit.
[0022] 2. In this utility model, when the hook catches the finished frame, the reaction force of the torsion spring can push the anti-detachment component to reset, so that one end of the anti-detachment component abuts against the inner wall of the hook, thereby preventing the hook from accidentally loosening or slipping, ensuring the stability of the hoisting, and thus avoiding the occurrence of falling accidents.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] Reference Figure 1-5 The tool-type external protective frame uses a tension sensor, which includes a protective frame 1. A tension sensor body 6 is installed inside the protective frame 1. A hook 2 is fixedly connected to the bottom of the tension sensor body 6. Several audible and visual alarms 5 are fixedly installed on the outside of the protective frame 1. Several buttons 8 are provided on one side of the tension sensor body 6. A controller 9 is fixedly installed on the rear side of the protective frame 1. An anti-detachment component is provided on the outside of the hook 2. The hook 2 can be used to hoist and connect the finished frame. Before hoisting, the preset value of the tension sensor body 6 can be set via the buttons 8. When the actual tension detected by the tension sensor body 6 exceeds the preset value, the controller 9 will activate the audible and visual alarms 5 to sound an alarm, thus reminding workers to handle the situation promptly. This allows for monitoring of the tension at each hoisting point during the hoisting of the finished frame, preventing excessive tension from causing deformation of the finished frame. Furthermore, the protective frame 1, built on top of the tension sensor body 6, mechanically limits the deformation space of the tension sensor body 6, preventing excessive damage when the tension sensor body 6 exceeds its limits.
[0031] Specifically, the anti-detachment component includes a rotating shaft 15 fixedly connected to the inner wall of the hook 2. Torsion springs 14 are fitted at both ends of the outer side of the rotating shaft 15. When the hook 2 hooks the finished frame, the reaction force of the torsion springs 14 pushes the anti-detachment component 16 to reset, causing one end of the anti-detachment component 16 to abut against the inner wall of the hook 2. This prevents the hook 2 from accidentally loosening or slipping, ensuring the stability of the hoisting and avoiding falling accidents. The anti-detachment component 16 is installed inside the hook 2 and is rotatably mounted on the rotating shaft 15 via the torsion springs 14. On the outside, the top of the protective frame 1 is fixedly connected to a limiting sleeve 13. A fixing post 4 is slidably installed inside the limiting sleeve 13. A hanging ear 3 is fixedly connected to the top of the fixing post 4. A limiting component is provided inside the limiting sleeve 13. The limiting component includes a limiting groove 11 opened inside the limiting sleeve 13. A limiting member 12 is fixedly connected to the outer periphery of the fixing post 4. Through the cooperation of the limiting groove 11 and the limiting member 12, the fixing post 4 and the hanging ear 3 can play an important limiting role, which can make the connection more stable. The limiting member 12 is slidably connected to the inner wall of the limiting groove 11.
[0032] Specifically, an LCD screen 7 is fixedly installed on the outside of the tension sensor body 6 and on the side of the button 8. The LCD screen 7 can display the tension value for easy viewing by staff. A battery pack 10 is built into the inside of the protective frame 1 and on the rear side of the tension sensor body 6. The battery pack 10 provides power to the controller 9, the audible and visual alarm 5, the LCD screen 7 and the tension sensor body 6 to ensure their normal operation. The end of the anti-detachment component 16 away from the rotating shaft 15 abuts against the inner wall of the hook 2 to improve connection stability.
[0033] Working principle: First, the hanging lug 3 can be connected to the hook on the crane. Then, the hook 2 is connected to the finished frame. Before hoisting, the preset value of the tension sensor body 6 can be set by the button 8. When the hook 2 hooks the finished frame, the reaction force of the torsion spring 14 can push the anti-detachment part 16 to reset, so that one end of the anti-detachment part 16 abuts against the inner wall of the hook 2, thereby preventing the hook 2 from accidentally loosening or slipping and ensuring the stability of the hoisting. Then, the crane is started. When the actual tension detected by the tension sensor body 6 exceeds the preset value, the controller 9 will control the sound and light alarm 5 to sound an alarm, so as to remind the staff to deal with it in time. In this way, the tension of each hoisting point can be monitored when the finished frame is hoisted. In addition, a protective frame 1 is set on the tension sensor body 6, which limits the deformation space of the tension sensor body 6 from the mechanical structure, preventing excessive damage to the tension sensor body 6 after exceeding the limit.
