Description

Technical Field

[0001] The utility model relates to the technical field of hoisting auxiliary devices for building electromechanical installation, and more specifically, to a hoisting auxiliary device for building electromechanical installation. Background Art

[0002] In modern construction projects, the installation of electromechanical equipment is a vital link. However, the current lifting technology and equipment still have many shortcomings, which not only affects the construction efficiency, but also may bring safety hazards. The traditional lifting method usually uses lifting machines and lifting rings to directly lift the building electromechanical equipment. The biggest problem with this method is that the equipment is in a completely exposed state during the lifting process and lacks necessary protection measures. This exposed lifting method has the risk of equipment falling off, collision damage risk and environmental impact. Due to the lack of effective fixing and protection measures, the equipment may fall off due to sudden external force or lifting equipment failure during the lifting process, causing serious safety accidents and property losses. During the lifting process, the exposed equipment can easily collide with the surrounding building structures or other equipment, causing damage to the equipment surface or deformation of the internal structure, affecting the normal function and service life of the equipment.

[0003] Although some construction units have begun to use lifting auxiliary equipment to improve this situation, the existing lifting auxiliary devices still have many shortcomings. The existing auxiliary devices often lack effective limiting and fixing mechanisms and cannot effectively prevent the equipment from shaking during the lifting process. This shaking not only increases the difficulty of operation, but may also cause the equipment to collide with surrounding objects and cause damage. The design of many auxiliary devices is too complicated and requires a lot of time to install, adjust and disassemble in actual use, which not only reduces construction efficiency but also increases construction costs. These problems seriously affect the practicability and reliability of the lifting auxiliary devices, making it impossible for them to fully play their expected protection and auxiliary roles.

[0004] In order to improve the efficiency of hoisting, some equipment manufacturers have tried to design quick connection and disassembly mechanisms to facilitate the rapid connection between electromechanical equipment and auxiliary equipment. However, these mechanisms still have problems such as insufficient stability and poor reliability. During the hoisting process, the equipment will inevitably shake or be impacted by external forces. The existing quick connection mechanisms are often unable to effectively cope with these situations and are prone to loosening or even falling off, greatly increasing the safety risks. The design of some quick connection mechanisms is too simple and lacks the necessary safety redundancy and fault protection mechanisms. They are prone to failures under long-term use or in harsh environments. These problems not only affect the efficiency and quality of building electromechanical installation, but may also bring serious safety hazards. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present utility model provides a hoisting auxiliary device for building mechanical and electrical installation, having the following beneficial effects:

[0018] 1. The design of the auxiliary device ingeniously solves the problem of the naked hoisting of mechanical and electrical equipment in the traditional hoisting method. The fixing frame provides all-round protection for the mechanical and electrical equipment, effectively preventing the possible collision and damage of the equipment during hoisting. The design of the entry slot enables the mechanical and electrical equipment to be easily pushed into the fixing frame, greatly simplifying the loading process.

[0020] 3. The design of the reinforcement mechanism ingeniously solves the possible loosening problem that may occur during the use of the quick-installation device. The combined design of the control sleeve, the large gear, the small gear, and the screw sleeve realizes the precise control and locking of the quick-release rod. The cooperation of the limiting sleeve, the limiting rod, and the limiting slot provides multiple protections for the entire mechanism. The setting of the connecting spring ensures that the limiting rod can automatically reset, increasing the reliability of the device. The threaded connection between the screw and the screw sleeve, combined with the guiding action of the slider and the chute, makes the entire reinforcement process more stable and controllable. This multiple protection mechanism not only effectively prevents the loosening and falling off of the connection structure but also greatly improves the use safety of the entire device. At the same time, this design also allows the operator to quickly release the limit when needed, providing convenience for the disassembly of the equipment in case of emergency.

[0032] Please refer to Figure 1-7, a hoisting auxiliary device for building mechanical and electrical installation, including a mechanical and electrical equipment 1, characterized in that: an auxiliary device is arranged outside the mechanical and electrical equipment 1, an installation plate 2 is connected to the bottom end of the mechanical and electrical equipment 1, a quick installation device is arranged on the installation plate 2, and the quick installation device includes a quick release sleeve 3, a clamping block 4, a quick release rod 5, a movable groove 6 and a longitudinal groove 7. The quick release sleeve 3 is detachably sleeved outside the quick release rod 5, the clamping block 4 is fixedly connected to the outside of the quick release rod 5, the movable groove 6 and the longitudinal groove 7 are both opened on the inner side of the quick release sleeve 3, and a reinforcement mechanism is arranged outside the quick release rod 5. The reinforcement mechanism includes a control sleeve 8, a large gear 9, a screw rod 10, a limiting sleeve 11, a small gear 12, a screw sleeve 13, a connecting spring 14, a limiting rod 15 and a limiting groove 16. The control sleeve 8 is rotatably sleeved outside the quick release sleeve 3, the large gear 9 is fixedly connected to one side of the control sleeve 8, the screw rod 10 and the screw sleeve 13 are movably connected by threads, the limiting sleeve 11 is slidably sleeved outside the quick release sleeve 3, the small gear 12 is fixedly connected to the outside of the screw sleeve 13, one end of the limiting rod 15 is connected to the outer wall of the quick release sleeve 3 through the connecting spring 14, and the other end of the limiting rod 15 is inserted into the limiting groove 16. A plurality of limiting grooves 16 are opened on the outside of the quick release sleeve 3.

[0033] A push spring 17 is arranged outside the quick release sleeve 3, and one end of the push spring 17 is connected to the limiting sleeve 11.

[0034] One end of the quick release rod 5 is connected with a connecting plate 18.

[0035] A fixed plate 19 is connected to the outside of the quick release sleeve 3, a slider 20 is arranged inside the fixed plate 19, a sliding groove 21 is correspondingly opened on the outside of the screw rod 10, and the sliding groove 21 is adapted to the slider 20.

[0036] An anti-slip strip 22 is connected to the outside of the control sleeve 8.

[0037] In this embodiment, when it is necessary to release the limit on the electromechanical device 1, first rotate the control sleeve 8, so that the control sleeve 8 drives the large gear 9 connected on one side to rotate. Then, the large gear 9 drives each small gear 12 meshed with it to rotate. Then, the small gear 12 drives the screw sleeve 13 to rotate. Since the screw rod 10 and the screw sleeve 13 are movably connected by threads, and the cooperation of the slider 20 and the chute 21 limits the screw rod 10 to prevent the screw rod 10 from rotating. Then, the screw rod 10 will slide along the slider 20 and the chute 21. At the same time, the push spring 17 will slowly reset and push the limit sleeve 11 to slide. Then, the limit sleeve 11 will no longer limit the limit rod 15. Then, rotate the quick-release rod 5 through the connecting plate 18. The quick-release rod 5 drives the limit groove 16 to rotate. Due to the rounded corner structure design at the edge of the limit groove 16 and the end of the limit rod 15, when the side wall of the limit groove 16 squeezes the end of the limit rod 15, one end of the limit rod 15 will slide out of the limit groove 16. At the same time, the other end of the limit rod 15 will drive the connecting spring 14 to stretch. Then, the quick-release rod 5 will drive the outer-connected block 4 to rotate in the movable groove 6. When the quick-release rod 5 and the block 4 cannot rotate, the position of the block 4 corresponds to the position of the longitudinal groove 7. Pull the quick-release sleeve 3 and the quick-release rod 5 to both sides respectively, and the quick-release sleeve 3 and the quick-release rod 5 can be removed. Then, the connecting spring 14 will drive the limit rod 15 to reset, so as to achieve the purpose of releasing the limit on the electromechanical device 1. When it is necessary to fix the electromechanical device 1 into the fixing frame 23, push the electromechanical device 1 into the fixing frame 23. Then, pass the quick-release rod 5 through the mounting hole from one side, and then sleeved the quick-release sleeve 3 on the outside of the quick-release rod 5 from the other side, and ensure that the longitudinal groove 7 corresponds to the position of the block 4. In this process, the top of the quick-release rod 5 will push the limit rod 15 to move, so that the limit rod 15 drives the connecting spring 14 to stretch again. When the quick-release sleeve 3 is completely sleeved on the outside of the quick-release rod 5, rotate the quick-release rod 5 in the reverse direction, so that the quick-release rod 5 drives the block 4 to rotate into the movable groove 6. When the quick-release rod 5 and the block 4 cannot rotate, the connecting spring 14 drives the limit rod 15 to snap into the original limit groove 16. Then, rotate the control sleeve 8 in the reverse direction. The control sleeve 8 drives the screw sleeve 13 to reverse through the cooperation of the large gear 9 and the small gear 12. Due to the limit of the slider 20 and the chute 21 on the screw rod 10, the screw rod 10 will slide back to its original position. At the same time, the screw rod 10 will push the limit sleeve 11 to slide back to its original position. Then, the limit sleeve 11 will squeeze the push spring 17 connected on one side. Then, the inner wall of the limit sleeve 11 will limit the outer end of the limit rod 15 again to prevent the limit rod 15 from moving. Then, the limit rod 15 and the limit groove 16 cooperate to limit the quick-release rod 5 to prevent the quick-release rod 5 from moving, thus ensuring the stability of the connection structure, effectively preventing the connection structure from loosening or even falling off, and improving the use safety of the equipment.

[0038] Please refer to Figure 1-3, as an implementation of the auxiliary device: The auxiliary device includes a fixing frame 23, an access slot 24, and a universal wheel 25. The fixing frame 23 is arranged outside the electromechanical device 1. The access slot 24 is opened inside the fixing frame 23. The universal wheel 25 is detachably installed below the mounting plate 2.

[0039] A reinforcing rod 26 is fixedly arranged inside the fixing frame 23.

[0040] A lifting ring 27 is connected to the top end of the fixing frame 23. The lifting ring 27 is detachably installed at the four corners of the top end of the fixing frame 23.

[0041] More specifically, when the device needs to be used, first push the electromechanical device 1 so that the electromechanical device 1 moves through the universal wheel 25 installed below the mounting plate 2. Then align the universal wheel 25 with the access slot 24, and then push the electromechanical device 1 into the inner side of the fixing frame 23, and make the universal wheel 25 enter the access slot 24. Then align the mounting holes opened on the mounting plate 2 with the mounting holes opened on the inner side of the fixing frame 23, and then limit and fix the electromechanical device 1 inside the fixing frame 23. The setting of the reinforcing rod 26 can enhance the structural strength of the fixing frame 23. Then connect the lifting ring 27 installed above the fixing frame 23 to an external lifting device, and then drive the lifting device to lift the fixing frame 23 and the electromechanical device 1 installed inside. After lifting to the appropriate floor, release the limitation and fixation of the electromechanical device 1, and then push the electromechanical device 1 out of the fixing frame 23 so that the electromechanical device 1 enters the designated floor.

[0042] In summary, when the overall device is in use or operation: when it is necessary to release the limit on the electromechanical device 1, first rotate the control sleeve 8, so that the control sleeve 8 drives the large gear 9 connected on one side to rotate, then the large gear 9 drives each small gear 12 meshed with it to rotate, and then the small gear 12 drives the screw sleeve 13 to rotate. Since the screw 10 and the screw sleeve 13 are movably connected by threads, and the cooperation of the slider 20 and the chute 21 limits the screw 10 to prevent the screw 10 from rotating, then the screw 10 will slide along the slider 20 and the chute 21. At the same time, the push spring 17 slowly resets and pushes the limiting sleeve 11 to slide, and then the limiting sleeve 11 will no longer limit the limiting rod 15. Then, rotate the quick-release rod 5 through the connecting plate 18, and the quick-release rod 5 drives the limiting groove 16 to rotate. Due to the rounded corner structure design at the edge of the limiting groove 16 and the end of the limiting rod 15, when the side wall of the limiting groove 16 squeezes the end of the limiting rod 15, one end of the limiting rod 15 will slide out of the limiting groove 16, and at the same time the other end of the limiting rod 15 will drive the connecting spring 14 to stretch. Then, the quick-release rod 5 will drive the clamping block 4 connected on the outside to rotate in the movable groove 6. When the quick-release rod 5 and the clamping block 4 cannot rotate, the position of the clamping block 4 corresponds to the position of the longitudinal groove 7. Pull the quick-release sleeve 3 and the quick-release rod 5 to both sides respectively, and the quick-release sleeve 3 and the quick-release rod 5 can be removed. Then, the connecting spring 14 will drive the limiting rod 15 to reset, so as to achieve the purpose of releasing the limit on the electromechanical device 1. When it is necessary to fix the electromechanical device 1 into the fixing frame 23, push the electromechanical device 1 into the fixing frame 23, then pass the quick-release rod 5 through the mounting hole from one side, and then sleeved the quick-release sleeve 3 on the outside of the quick-release rod 5 from the other side, and ensure that the longitudinal groove 7 corresponds to the position of the clamping block 4. In this process, the top of the quick-release rod 5 will push the limiting rod 15 to move, so that the limiting rod 15 drives the connecting spring 14 to stretch again. When the quick-release sleeve 3 is completely sleeved on the outside of the quick-release rod 5, rotate the quick-release rod 5 in the reverse direction, so that the quick-release rod 5 drives the clamping block 4 to turn into the movable groove 6. When the quick-release rod 5 and the clamping block 4 cannot rotate, the connecting spring 14 drives the limiting rod 15 to snap into the original limiting groove 16. Then, rotate the control sleeve 8 in the reverse direction. The control sleeve 8 drives the screw sleeve 13 to reverse through the cooperation of the large gear 9 and the small gear 12. Due to the limit of the slider 20 and the chute 21 on the screw 10, the screw 10 will slide back to its original position. At the same time, the screw 10 will push the limiting sleeve 11 to slide back to its original position. Then, the limiting sleeve 11 will squeeze the push spring 17 connected on one side, and then the inner wall of the limiting sleeve 11 will limit the outer end of the limiting rod 15 again to prevent the limiting rod 15 from moving. Then, the limiting rod 15 and the limiting groove 16 cooperate to limit the quick-release rod 5 to prevent the quick-release rod 5 from moving, thus ensuring the stability of the connection structure, effectively preventing the connection structure from loosening or even falling off, and improving the use safety of the device.

[0043] When the device needs to be used, first push the electromechanical device 1 so that the electromechanical device 1 moves through the universal wheels 25 installed under the mounting plate 2. Then align the universal wheels 25 with the entry slot 24, and then push the electromechanical device 1 into the inner side of the fixing frame 23, and make the universal wheels 25 enter the entry slot 24. Then align the mounting holes formed on the mounting plate 2 with the mounting holes formed on the inner side of the fixing frame 23. Then limit and fix the electromechanical device 1 inside the fixing frame 23. The arrangement of the reinforcing rod 26 can enhance the structural strength of the fixing frame 23. Then connect the lifting ring 27 installed above the fixing frame 23 with an external lifting device. Then drive the lifting device to lift the fixing frame 23 and the electromechanical device 1 installed inside. After lifting to the appropriate floor, release the limitation and fixation of the electromechanical device 1, and then push the electromechanical device 1 out of the fixing frame 23, so that the electromechanical device 1 enters the designated floor.
