[0013] A method for installing a hanger for a machine-room-less elevator comprises the installation structure for a hanger for a machine-room-less elevator described in any one of the above, and further comprises the following steps:

[0014] Step 1: Install the bracket body

[0015] Position the lower beam horizontally at a predetermined position in the shaft and fix it to the shaft structure with anchor bolts. Then, vertically connect two sets of cross beams to the two ends of the lower beam to form a support frame. Then, install two sets of progressive safety clamps symmetrically on both sides of the cross beam to ensure that the jaws are aligned with the guide rails.

[0016] Step 2: Fixing the vertical beam

[0017] Insert the lower ends of the two groups of vertical beams between the two groups of fixing brackets on one side of the two groups of horizontal beams, adjust the positions of the lower ends of the two groups of vertical beams so that the fixing rods are aligned with the fixing holes on one side of the fixing brackets, insert the fixing rods and then install locking nuts to secure them;

[0018] Synchronously install linkage components

[0019] Insert the two ends of the linkage rod through the reserved holes on one side of the two groups of beams, connect the two ends of the linkage rod to the two groups of linkage plates, then connect the linkage plates to the progressive safety gear, then install the spring and the insertion rod, adjust the insertion rod and insert it into the corresponding insertion hole to achieve linkage locking;

[0020] Step 3: Installation of upper beam and traction sheave

[0021] Install the support plate on the upper end of the vertical beam, fix the mounting plate to the top of the support plate by bolts, hoist the two sets of upper beams above the two sets of mounting plates, align the mounting rods with the mounting holes and then plug and fix them, then install the traction wheel between the two sets of connecting plates through the rotating shaft, and then fix the two sets of connecting plates to the side walls of the upper beam by bolts;

[0022] Step 4: Protective component assembly

[0023] Cover the top of the two sets of upper beams with the first protective shell, then extend the two sets of the third protective shells on both sides and install them on the top of the two sets of upper beams, then install the second protective shells on the bottom of the two sets of upper beams and fix them to the bottom of the upper beams with bolts, and then check the sealing of the joints of each protective shell to ensure that the traction sheave is protected;

[0024] Step 5: Inspection and debugging after hanger installation

[0025] First, manually trigger the progressive safety clamp to verify the synchronous action of the linkage rod driving the double safety clamp, then test the plugging and unplugging flexibility of the plug rod under the action of the spring to ensure the emergency locking function, then perform a no-load test on the traction sheave, observe the vibration and abnormal noise of the protection component, and complete the installation.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention uses a bracket body, a vertical beam, a fixing assembly, an upper beam and an installation assembly in combination, so that the device is designed to be independently assembled with a split bracket body, vertical beams and upper beams, thereby reducing the complexity of on-site construction and allowing the device to adapt to different shaft sizes.

[0028] 2. The present invention uses a lower beam, a cross beam, a progressive safety clamp and a linkage component in combination. The cross-fixation of the lower beam and the cross beam forms a stable rectangular frame, which is directly anchored to the shaft structure to provide a solid foundation for the vertical beam and the upper beam, avoiding deformation caused by uneven car load, dispersing the dynamic load during elevator operation, reducing stress concentration, and preventing the overall deviation of the hanger through the anchor bolts. The progressive safety clamps with symmetrical arrangement of the two sets of cross beams form a dual redundant braking mechanism. When the elevator overspeeds or loses control, the dual safety clamps synchronously clamp the guide rails to avoid the risk of unilateral failure. The linkage component ensures the consistency of the action of the safety clamps on both sides to prevent the car from tilting.

[0029] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] See also Figure 1-6 The present invention provides a technical solution: an installation structure and installation method for a machine room-less elevator hanger, comprising a bracket body for supporting the elevator car, two sets of vertical beams 1 are provided on both sides of the bracket body, and fixing components for fixing the vertical beams 1 are provided between the lower ends of the two sets of vertical beams 1 and the two sides of the bracket body, two sets of upper beams 2 are provided between one side of the upper ends of the two sets of vertical beams 1, and installation components for installing the upper beams 2 are provided between the two ends of the two sets of upper beams 2 and one side of the two sets of vertical beams 1, two sets of traction sheaves 3 are provided between the two ends of one side of the two sets of upper beams 2, two sets of connecting plates 4 are connected to one side of the two sets of upper beams 2 by rotating shafts, and one side of the two sets of connecting plates 4 is connected to one side of the two sets of upper beams 2, and a protective component for protecting the traction sheave 3 is provided on the outside of the two sets of traction sheaves 3 and on the surface of the two sets of upper beams 2.

[0039] Specifically, by using the bracket body, vertical beam 1, fixing assembly, upper beam 2 and installation assembly in combination, the two sets of vertical beams 1 are fixed to the two sides of the bracket body by using the fixing assembly, and then the two sets of upper beams 2 are connected to the upper ends of the two sets of vertical beams 1 by using the installation assembly. The device is designed with a split bracket body, independent assembly of vertical beam 1 and upper beam 2, which reduces the complexity of on-site construction and allows the device to adapt to different shaft sizes. It solves the problem that the traditional elevator car frame is difficult to install due to the large number of loose parts and heavy straight beams during on-site assembly, so that the device can be installed in steps in a narrow shaft, saving time and effort and improving the adaptability of the device.

[0040] Preferably, the bracket body includes: a lower beam 5, a cross beam 6, a progressive safety clamp 7 and a linkage assembly. Two groups of cross beams 6 are fixedly installed at both ends of the lower beam 5, and one side of the two groups of cross beams 6 is connected to the two groups of vertical beams 1 through a fixed assembly. One side of the two groups of cross beams 6 is provided with a progressive safety clamp 7. One side of the two groups of progressive safety clamps 7 is connected with a linkage assembly for controlling the two groups of progressive safety clamps 7 to be linked. The progressive safety clamp 7 achieves smooth deceleration and reduces the impact of sudden stops on passengers through the characteristic that the friction force increases with the clamping force.

[0041] Through the coordinated use of the lower beam 5, the cross beam 6, the progressive safety clamp 7 and the linkage assembly, the cross fixation of the lower beam 5 and the cross beam 6 forms a stable rectangular frame, which is directly anchored to the shaft structure, providing a solid foundation for the vertical beam 1 and the upper beam 2, avoiding deformation caused by uneven car load, dispersing the dynamic load during elevator operation, reducing stress concentration, and being rigidly connected to the shaft through anchor bolts to prevent the overall deviation of the hanger. The progressive safety clamp 7 symmetrically arranged on the two sets of cross beams 6 forms a dual redundant braking mechanism. When the elevator overspeeds or loses control, the dual safety clamps synchronously clamp the guide rail to avoid the risk of unilateral failure. The linkage assembly ensures the consistency of the safety clamps on both sides to prevent the car from tilting.

[0042] Preferably, the fixing assembly includes: a fixing frame 8, a fixing hole 9 and a fixing rod 10, four groups of fixing frames 8 are fixedly installed on one side of the two groups of cross beams 6, and every two groups of fixing frames 8 are respectively located on both sides of the progressive safety clamp 7, and a plurality of groups of fixing holes 9 are evenly opened on one side of the fixing frame 8, and a plurality of groups of fixing rods 10 are arranged on both sides of the lower end of the two groups of vertical beams 1, and one end of the fixing rod 10 is arranged corresponding to the interior of the fixing hole 9, and one end of the fixing rod 10 is plugged into the inner cavity of the fixing hole 9. Through the coordinated use of the fixing frame 8, the fixing hole 9 and the fixing rod 10, the lower end of the vertical beam 1 is first plugged between the two groups of fixing frames 8, and then locked using the fixing rod 10 and the fixing hole 9, thereby utilizing the dual fixing mechanism of plug-in and locking to ensure the stable connection between the vertical beam 1 and the bracket body, adapt to the complex shaft environment and resist long-term vibration.

[0043] As a preferred embodiment, the linkage assembly includes: a linkage rod 18, a linkage plate 19, a spring 20, a plug rod 21 and a socket 22. The linkage rod 18 is rotatably connected between one side of the two sets of beams 6. Two ends of the linkage rod 18 are connected to two sets of linkage plates 19, and one end of the linkage plate 19 is connected to one end of the progressive safety gear 7. Springs 20 are provided at both ends of the surface of the linkage rod 18 and are located between the two sets of beams 6. One end of the spring 20 is connected to the linkage rod 18, and the other end of the spring 20 is provided with a plug rod 21. Several sets of sockets 22 is evenly penetrated and opened on one side of the two groups of cross beams 6. The interior of the socket 22 is corresponding to one end of the plug rod 21, and one end of the plug rod 21 is plugged into the inner cavity of the socket 22. The design of the linkage rod 18 spring 20 and the plug rod 21 realizes the synchronous triggering of the dual safety clamps. When the safety clamp on one side is abnormal, the linkage assembly is forced to act synchronously to avoid the car tilting and blocking, improve the reliability of emergency braking, and avoid equipment damage caused by traditional instantaneous locking. The locking mechanism of the plug rod 21 provides additional emergency protection for maintenance or emergencies.

[0044] Preferably, the mounting assembly includes: a support plate 11, a mounting plate 12, a mounting hole 13 and a mounting rod 14. Two groups of support plates 11 are fixedly installed on the upper end of one side of the vertical beam 1. The top of the support plate 11 is connected to the mounting plate 12 by bolts. The tops of the two groups of mounting plates 12 are connected to the two ends of the bottom of the two groups of upper beams 2 by bolts. Several groups of mounting holes 13 are opened at both ends of one side of the two groups of upper beams 2. Several groups of mounting rods 14 are arranged on both sides of the upper ends of the two groups of vertical beams 1. One end of the mounting rod 14 is adapted to the interior of the mounting hole 13, and one end of the mounting rod 14 is plugged into the inner cavity of the mounting hole 13. The combined design of plugging the mounting rod 14 and the mounting hole 13 with the matching bolts makes it convenient to install or disassemble the upper beam 2, and facilitates the rapid replacement of the traction wheel 3 or adjustment of the steel cable tension during later maintenance, thereby reducing downtime.

[0045] Preferably, the protective assembly includes: a first protective shell 15, a second protective shell 16 and a third protective shell 17.

[0046] Specifically, through the coordinated use of the first protective shell 15, the second protective shell 16 and the third protective shell 17, the first protective shell 15, the second protective shell 16 and the third protective shell 17 are connected to the upper beam 2 by split bolts. The first protective shell 15 and the third protective shell 17 are used to cover the top of the traction sheave 3, and the second protective shell 16 closes the bottom, forming an anti-foreign matter environment, extending the life of the traction sheave 3, protecting the equipment while avoiding occupying additional space, and facilitating disassembly and maintenance, thereby reducing downtime.

[0047] A method for installing a hanger for a machine-room-less elevator comprises any one of the above-mentioned installation structures for a hanger for a machine-room-less elevator, and further comprises the following steps:

[0048] Step 1: Install the bracket body

[0049] Position the lower beam 5 horizontally at the predetermined position of the shaft, calibrate it with a laser level, and then fix it to the shaft load-bearing structure with anchor bolts. The anchoring of the lower beam 5 directly transfers the load to the shaft structure, which can avoid the risk of the hanger sinking. Then, connect two sets of cross beams 6 vertically to the two ends of the lower beam 5 to form a support frame, ensuring that the cross beam 6 is parallel to the shaft guide rail. Then, install two sets of progressive safety clamps 7 symmetrically on both sides of the cross beam 6, ensure that the jaws are aligned with the guide rail, and fix them. The symmetrical arrangement of the double safety clamps can improve braking reliability. At the same time, the synchronous installation of the safety clamps and the bracket body reduces the workload of subsequent debugging.

[0050] Step 2: Fixing the vertical beam 1

[0051] Insert the lower ends of the two sets of vertical beams 1 between the two sets of fixing brackets 8 on one side of the two sets of cross beams 6, and then adjust the positions of the lower ends of the two sets of vertical beams 1 so that the fixing rods 10 are aligned with the fixing holes 9 on one side of the fixing brackets 8. Then, insert the fixing rods 10 and install the locking nuts to fix them. The design of the fixing brackets 8 and the fixing holes 9 enables one-click centering of the vertical beams 1, reducing manual measurement errors. The dual fixation of the fixing rods 10 and the locking nuts can resist the vibration caused by starting and stopping the elevator.

[0052] Synchronously install linkage components

[0053] The two ends of the linkage rod 18 are passed through the reserved holes on one side of the two sets of crossbeams 6, so that the two ends are connected to the two sets of linkage plates 19 through pins. Then, one end of the linkage plate 19 is hinged to the trigger arm of the progressive safety clamp 7. Then, the spring 20 and the plug rod 21 are installed. The plug rod 21 is adjusted and inserted into the corresponding hole 22 to achieve linkage locking. The single linkage rod 18 synchronously controls the dual safety clamps, eliminating the risk of eccentric loading caused by action delay. The pre-tightening design of the plug rod 21 and the spring 20 allows manual or automatic triggering of the lock in an emergency.

[0054] Step 3: Installation of upper beam 2 and traction sheave 3

[0055] Install the support plate 11 at the upper end of the vertical beam 1, fix the mounting plate 12 to the top of the support plate 11 with high-strength bolts, hoist the two sets of upper beams 2 to the top of the two sets of mounting plates 12, align the mounting rods 14 with the mounting holes 13 and then plug and fix them. Then install the traction sheave 3 between the two sets of connecting plates 4 through the rotating shaft. Apply lithium-based grease to the rotating shaft, and then fix the two sets of connecting plates 4 to the side walls of the upper beam 2 with bolts. The separate installation of the upper beam 2 and the traction sheave 3 reduces the difficulty of hoisting large components in the hoistway. The bolt connection between the connecting plate 4 and the upper beam 2 allows slight deformation to absorb the operating vibration of the traction sheave 3, which can reduce resonance transmission and extend the bearing life.

[0056] Step 4: Protective component assembly

[0057] A first protective shell 15 is covered on the top of the two sets of upper beams 2, and two sets of third protective shells 17 are extended on both sides thereof and installed on the top of the two sets of upper beams 2. Then, a second protective shell 16 is installed on the bottom of the two sets of upper beams 2 and fixed to the bottom of the upper beams 2 with bolts. The joints are filled with silicone sealant, and then the sealing of the joints of each protective shell is checked to ensure that the traction sheave 3 is protected and foreign objects are prevented from entering, causing the traction sheave 3 to get stuck or the wire rope to wear, thereby extending the service life of the bearings and gears in harsh environments. At the same time, the modular shell is easy to disassemble and maintain locally without having to dismantle the entire shell. Damping material is attached to the inside of the protective shell to reduce the operating noise of the traction sheave 3.

[0058] Step 5: Inspection and debugging after hanger installation

[0059] First, manually trigger the progressive safety clamp 7 to verify the synchronous action of the linkage rod 18 driving the dual safety clamps, then test the plug-in and pull-out flexibility of the plug-in rod 21 under the action of the spring 20 to ensure the emergency locking function, and then perform a no-load test on the traction wheel 3 to observe the vibration and abnormal noise of the protection components. Complete the installation to ensure that the safety mechanism and power system meet the design performance, meet the acceptance requirements through standardized testing procedures, and reduce the risk of complaints.

[0060] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

Step 2: Fixing the vertical beam (1) Insert the lower ends of the two groups of vertical beams (1) between the two groups of fixing frames (8) on one side of the two groups of horizontal beams (6), adjust the positions of the lower ends of the two groups of vertical beams (1) so that the fixing rods (10) thereof are aligned with the fixing holes (9) on one side of the fixing frames (8), and then insert the fixing rods (10) and install locking nuts to secure them; Synchronously install linkage components The two ends of the linkage rod (18) are passed through the reserved holes on one side of the two groups of cross beams (6), so that the two ends are connected to the two groups of linkage plates (19), and then the linkage plates (19) are connected to the progressive safety clamp (7), and then the spring (20) and the insertion rod (21) are installed, and the insertion rod (21) is adjusted to be inserted into the corresponding insertion hole (22) to achieve linkage locking; Step 3: Installation of upper beam (2) and traction sheave (3) The support plate (11) is installed on the upper end of the vertical beam (1), and the mounting plate (12) is fixed to the top of the support plate (11) by bolts. The two sets of upper beams (2) are hoisted above the two sets of mounting plates (12), and then the mounting rods (14) are aligned with the mounting holes (13) and then plugged and fixed. Then, the traction wheel (3) is installed between the two sets of connecting plates (4) through the rotating shaft, and then the two sets of connecting plates (4) are fixed to the side walls of the upper beam (2) by bolts. Step 4: Protective component assembly The first protective shell (15) is covered on the top of the two groups of upper beams (2), and two groups of the third protective shells (17) are extended and installed on both sides of the first protective shell (15) on the top of the two groups of upper beams (2). Then, the second protective shell (16) is installed on the bottom of the two groups of upper beams (2) and fixed to the bottom of the upper beams (2) by bolts. Then, the sealing of the joints of each protective shell is checked to ensure that the traction wheel (3) is protected. Step 5: Inspection and debugging after hanger installation First, manually trigger the progressive safety clamp (7) to verify the synchronous action of the linkage rod (18) driving the dual safety clamps, then test the plug-in and pull-out flexibility of the plug rod (21) under the action of the spring (20) to ensure the emergency locking function, and then perform a no-load test on the traction sheave (3) to observe the vibration and abnormal sound of the protection component to complete the installation.
