Technical Field
[0001] This utility model relates to the field of hanger technology, specifically to an elevator hanger installation structure. Background Technology
[0002] Elevator hangers are supporting structures used during elevator installation and maintenance to temporarily suspend and fix components such as the car, counterweight, or guide rails. They typically consist of a beam, hooks, a hoist (manual or electric), and safety locks. Their function is to ensure safety during high-altitude operations, adjust the position of components, and assist in the handling of heavy equipment. Depending on their application, they can be categorized into manual hoist hangers, electric hangers, and guide rail installation hangers. When using them, it is essential to strictly verify the load-bearing capacity, firmly fix the supports, and comply with safety regulations to ensure construction safety.
[0003] Loose bolts on elevator hangers can lead to serious consequences, including structural instability, reduced load-bearing capacity, and potentially causing a multi-ton elevator car or counterweight to fall from a great height, resulting in equipment damage, project delays, and personal injury. More seriously, this loosening is often insidious and gradual, difficult to detect visually in its early stages, and by the time noticeable displacement appears, the elevator is often nearing critical failure. Long-term, minor loosening can also accelerate bolt thread wear, triggering a chain reaction of structural failures. Traditional manual inspection methods have blind spots and are prone to subjective errors, further amplifying safety risks.
[0004] According to the authorization announcement number CN 220033721 U, an elevator hanger is disclosed, which includes a first connecting plate and a second connecting plate. The first connecting plate and the second connecting plate are detachably connected. A reinforcing member is provided between the first connecting plate and the second connecting plate to increase the connection strength between the first connecting plate and the second connecting plate. A first reinforcing rib is fixedly connected to the first connecting plate, and a second reinforcing rib is fixedly connected to the second connecting plate. A winding wheel is provided between the first connecting plate and the second connecting plate. One end of the winding wheel is rotatably connected to the first reinforcing rib, and the other end of the winding wheel is rotatably connected to the second reinforcing rib. A steel wire rope is wound on the winding wheel.
[0005] Most existing elevator hangers are installed using bolts. However, after prolonged use, the bolts may loosen, affecting the safety of the entire structure. Therefore, there is a need for a new elevator hanger installation structure. Utility Model Content
[0006] The purpose of this utility model is to provide an elevator hanger installation structure that uses a U-shaped plate to hold the bolts in place, preventing them from loosening and falling off after prolonged use, thus solving the technical problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An elevator hanger installation structure includes a fixed plate, a movable groove is provided in the middle of the fixed plate, two sets of extension frames are symmetrically installed on both sides of the middle of the movable groove, and several sets of bolts are installed through the middle of the extension frames.
[0009] Each set of extension frames has several sets of sliding grooves corresponding to the bolts in the middle. A U-shaped block is slidably installed inside each set of sliding grooves. Each set of bolts is located between the corresponding U-shaped block and the extension frame. A limit block is installed inside each set of sliding grooves on the side of the corresponding U-shaped block.
[0010] Preferably, each set of limiting blocks has two sets of circular grooves symmetrically opened on the upper and lower sides, and a spring is installed inside each set of circular grooves.
[0011] Preferably, one end of each set of springs is fitted with a locking block inside the circular groove, and one end of each set of locking blocks is hemispherical.
[0012] Preferably, the inner wall of each set of sliding grooves has a corresponding slot for the locking block, and each set of locking blocks is engaged with the inside of the corresponding slot.
[0013] Preferably, a fixing frame is installed at the bottom of the fixing plate between the two sets of extension frames, a fixing rod is installed inside the fixing frame, and a guide wheel is installed in the middle of the fixing rod inside the fixing frame.
[0014] Preferably, a connecting plate is installed between each set of extension frames and the fixed frame, and reinforcing plates are installed on both sides of each set of connecting plates and the corresponding extension frames.
[0015] Preferably, a top plate is installed on the upper part of the fixing plate, and the top plate is connected to the top structure of the elevator shaft by bolts.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] After the hanger is installed, the extension frame is securely fixed to the wall with bolts. The U-shaped block is aligned with the slide groove, and a pushing force is applied to fully embed it into the groove. At this point, the inner wall of the U-shaped block tightly grips the bolt head. Finally, the limiting block is inserted into the pre-drilled position in the slide groove. The synergistic action of the U-shaped block and the slide groove forms a double locking mechanism. This cooperation between the U-shaped block and the slide groove effectively prevents bolts from loosening or falling off due to long-term vibration or load, improving the stability and safety performance of the entire hanger structure and ensuring long-term reliable operation of the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] This utility model provides: an elevator hanger installation structure, such as... Figures 1-5 As shown, the system includes a fixed plate 1, a movable groove 2 in the middle of the fixed plate 1, two sets of extension frames 3 symmetrically installed on both sides of the movable groove 2 on both sides of the fixed plate 1, and several sets of bolts 4 through the middle of the extension frames 3. The movable groove 2 in the middle of the fixed plate 1, together with the setting of the extension frames 3, allows the position of the extension frames 3 to be flexibly adjusted according to the actual elevator installation space, layout requirements, etc. during the installation process, so as to better adapt to different installation scenarios and improve the versatility of the installation structure. The bolts 4 can provide stronger fastening force to ensure that the connection between the extension frames 3 and the fixed plate 1 and other connecting parts is stable and reliable.
[0026] Each set of extension frames 3 has several sets of sliding grooves 5 corresponding to the bolts 4 in the middle. A U-shaped block 6 is slidably installed inside each set of sliding grooves 5. Each set of bolts 4 is positioned between the corresponding U-shaped block 6 and the extension frame 3. A limit block 7 is installed inside each set of sliding grooves 5 on the side of the corresponding U-shaped block 6. The multiple sets of sliding grooves 5 in the middle of the extension frame 3 corresponding to the bolts 4 allow the U-shaped block 6 to slide flexibly, facilitating quick alignment of the bolt position and simplifying the assembly process. The U-shaped block 6 clamps the bolts 4 and is fixed in conjunction with the limit block 7, forming a mechanical interlocking structure that effectively resists bolt loosening caused by vibration, impact, or long-term load, significantly improving safety. If the bolts 4 need to be replaced or maintained, simply remove the limit block 7 and slide out the U-shaped block 6 without damaging the overall structure, reducing maintenance costs and extending the service life of the hanger.
[0027] Preferably, each set of limiting blocks 7 has two sets of circular grooves 8 symmetrically opened on the upper and lower sides. A spring 9 is installed inside each set of circular grooves 8. The springs 9 installed in the circular grooves 8 on the upper and lower sides of the limiting blocks 7 form an elastic support structure, which can effectively absorb vibration or impact energy, reduce the force fluctuation of bolts 4 and U-shaped blocks 6, and improve the overall seismic performance. The elastic force of the springs 9 keeps the limiting blocks 7 dynamically pressed in the sliding groove 5. Even if slight wear occurs due to long-term use, it can still automatically compensate for the gap, ensuring that the U-shaped blocks 6 always tightly clamp the bolts 4 and prevent loosening.
[0028] Furthermore, a locking block 10 is installed at one end of each set of springs 9 inside the circular groove 8. One end of each locking block 10 is hemispherical and fixed to the end of the spring 9. Its hemispherical design can form point contact with the inner wall of the circular groove 8, effectively preventing the spring from shifting laterally under vibration or impact, ensuring that the elastic force always acts perpendicularly on the limiting block 7, and improving stability. When the arc surface of the hemispherical locking block 10 contacts the inner wall of the circular groove 8, the friction area is small and the sliding is smooth, reducing metal wear, avoiding the spring 9 from losing elastic force due to long-term friction, and extending the service life of key components.
[0029] Furthermore, each set of slide grooves 5 has a corresponding slot 11 on its inner wall corresponding to the locking block 10. Each set of locking blocks 10 is locked into the interior of the corresponding slot 11. The rigid locking of the locking block 10 and the slot 11 prevents the spring 9 from dislodging from the circular groove 8 under vibration or impact, thus avoiding the failure of the limit due to spring displacement. The constraint effect of the slot 11 on the locking block 10 ensures that the elastic force of the spring 9 is strictly transmitted along the axial direction of the slide groove 5, thus avoiding local wear of the U-shaped block 6 or the limit block 7 due to off-center load.
[0030] It is worth noting that a fixed frame 12 is installed at the bottom of the fixed plate 1 between the two sets of extension frames 3. A fixed rod 13 is installed inside the fixed frame 12. A guide wheel 14 is installed in the middle of the fixed rod 13 inside the fixed frame 12. The fixed frame 12 serves as a reinforcing frame and connects the two sets of extension frames 3, which can effectively distribute the force and reduce the twisting or deformation caused by unilateral load. The guide wheel 14 is installed in the middle of the fixed rod 13 and can roll to guide the direction of the rope, cable or chain, avoiding direct friction against the inner wall of the fixed frame 12.
[0031] Specifically, a connecting plate 15 is installed between each set of extension frames 3 and the fixed frame 12. Each set of connecting plates 15 and the corresponding extension frames 3 are equipped with reinforcing plates 16 on both sides. The connecting plate 15 serves as a transition support between the extension frame 3 and the fixed frame 12, optimizing the force transmission path and avoiding stress concentration that could lead to local deformation or cracking. The reinforcing plates 16 form a reinforced structure on both sides of the connecting plate 15, significantly improving bending and torsional resistance.
[0032] More specifically, a top plate 17 is installed on the upper part of the fixed plate 1. The top plate 17 is connected to the top structure of the elevator shaft by bolts. The top plate 17 serves as a connecting transition between the hanger and the top of the elevator shaft, expanding the contact surface for stress and allowing the load to be transferred to the building structure more evenly, avoiding local stress concentration. The top plate 17 has pre-drilled standardized bolt holes, which can be flexibly matched with the embedded parts or steel structure at the top of the elevator shaft, simplifying the installation process.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
