Description

Technical Field

[0001] This invention belongs to the technical field of fixing structure for elevator machine room components, specifically relating to an integrated axisymmetric fixing structure for elevator machine room components. Background Technology

[0002] With the increasing prevalence of high-rise buildings, machine-room elevators have become core equipment in modern building vertical transportation. The structural rationality of the fixing structure design of their machine room components directly affects the elevator's smoothness, safety, comfort, and service life. Traditionally, the fixing of machine room components typically consists of mounting bases, guide wheel assemblies, and wire rope termination devices. These often employ asymmetrical support structures, and dynamic components (such as guide wheels and wire rope termination devices) are directly and rigidly mounted on load-bearing steel beams. Vibration and noise are transmitted to the building structure through these beams, resulting in poor noise and vibration reduction. The asymmetrical stress concentration, scattered installation components, and the fact that one side of the traction machine's output end is often suspended and subjected to gravity can cause tilting, affecting the elevator's operational safety. Summary of the Invention

[0003] In view of the problems of asymmetric stress concentration, noise pollution caused by vibration transmission path coupling, and the risk of tilting of the traction machine affecting elevator safety in the existing technology, the present invention provides an integrated axisymmetric fixing structure for elevator machine room components. The purpose is to solve the above problems by using an axisymmetric layout with the center of the traction wheel as the reference and adding a shock absorption device and an axial force compensation device.

[0004] The technical solution adopted in this invention is as follows: An integrated elevator machine room component axisymmetric fixing structure, characterized in that it comprises: Load-bearing beam; A shock-absorbing device is mounted on the load-bearing beam and is fixedly connected to the load-bearing beam. The mounting base is disposed on the shock absorber and is fixedly connected to the shock absorber. The shock absorber is located between the load-bearing beam and the mounting base. A traction machine is mounted on the mounting base and fixedly connected to the mounting base. The mounting base is located between the shock absorption device and the traction machine. A preload device is provided on the mounting base and is fixedly connected to the mounting base. The preload device is higher than the traction machine and is hinged to the traction machine to provide an upward preload force to the traction machine. A wire rope termination device includes: a first termination device and a second termination device, wherein the first termination device is fixedly connected to one side of the mounting base; the second termination device is fixedly connected to the other side of the mounting base; the first termination device and the second termination device are symmetrically distributed with the output shaft of the traction machine as the center. An axial force compensation device is provided on the mounting base and is fixedly connected to the mounting base. The axial force compensation device also abuts against the output end of the traction machine.

[0005] The noise of the traction machine is reduced by connecting the load-bearing beam and the mounting base through a shock-absorbing device; the traction machine is hinged by a pre-tensioning device to provide an upward force to the traction machine, so that the output end of the traction machine will not overturn due to the uneven force on both sides when it is operating; the axial force compensation device abuts against the output end face of the traction machine, and when the traction machine deviates, the axial force compensation device can apply a compensating force to the traction machine to cope with it.

[0006] Preferably, the shock absorption device includes: A rubber spring, which is fixedly connected between the load-bearing beam and the mounting base; An anti-tipping device is provided, which passes through the mounting base and the rubber spring, is slidably connected to the mounting base, and is threadedly connected to the rubber spring. A failure prevention device is provided on the mounting base and is threadedly connected to the mounting base. One end of the failure prevention device is inserted into the rubber spring, and the failure prevention device is slidably connected to the rubber spring.

[0007] Using the above scheme, the anti-tipping device allows the mounting base to move flexibly in the vertical direction, and the device that passes through the mounting base and the rubber spring can prevent tipping after the rubber spring fails. The anti-failure device does not affect the vibration damping effect of the rubber spring. When the rubber spring fails, the anti-failure device temporarily supports the mounting base, providing safety protection.

[0008] Preferably, the preload device includes: A fixed support frame is fixedly connected to the mounting base, and the fixed support frame is higher than the traction machine; A locking rod is provided on the fixed frame. One end of the locking rod is hinged to the upper end of the fixed frame, and the other end of the locking rod is hinged to the traction machine. The locking rod provides preload to the fixed frame and the traction machine by rotating.

[0009] Preferably, the locking rod includes: The first hinge part is hinged to the fixed frame; The second hinge part is hinged to the traction machine, and a threaded hole is provided in the second hinge part; A rotating part is provided between the first hinge part and the second hinge part. One end of the rotating part is rotatably connected to the first hinge part, and the other end of the rotating part is threadedly connected to the second hinge part.

[0010] Using the above scheme, after the first hinge part is hinged to the fixed frame and the second hinge part is hinged to the traction machine, the preload is adjusted by rotating the rotating part, so that the fixed frame fixes the traction machine from the top, preventing it from running off-center. In addition, the threaded connection has a certain self-locking function, which can prevent loosening from causing insufficient preload.

[0011] Preferably, the axial force compensation device includes: A bearing housing is provided on one side of the output end of the traction machine, and the bearing housing is fixedly connected to the mounting base; A hydraulic rod is mounted on the bearing seat and is fixedly connected to the bearing seat. The output end of the hydraulic rod abuts against the output end of the traction machine.

[0012] Using the above scheme, the hydraulic rod abuts against the output end of the traction machine. When the traction machine tilts, the hydraulic rod senses the change in pressure and compensates the traction machine with force, so that the output end of the traction machine always remains in the same position.

[0013] Preferably, the axis of the hydraulic rod is collinear with the axis of the traction machine.

[0014] Preferably, the shock-absorbing devices are symmetrically distributed on the load-bearing beam with the output shaft of the traction machine as the center.

[0015] Preferably, the traction machine is fixedly connected to the mounting base by bolts, and the bolts are equipped with anti-loosening washers.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The axisymmetric integrated fixing structure of the elevator machine room components ensures that the horizontal forces are symmetrically equal with respect to the center of the traction sheave, and the horizontal deformation displacement is symmetrically equal, effectively improving the problem of asymmetrical stress concentration. Breaking away from the traditional stepped interactive stacking structure of the mounting base, the mounting base structure is creatively reconstructed and laid out symmetrically with respect to the center of the traction sheave. This not only improves the imbalance of forces in the horizontal direction, but also provides vertical support through rods formed by shaped channel steel, facilitating vertical dimension adjustment. The structure is simple and reduces material costs.

[0017] 2. By using a pre-tensioning device and an axial force compensation device, the traction machine is stabilized statically, and a dynamic compensation force is applied. The axial force compensation device corrects the deviation of the traction machine output end in real time, ensuring the stability of the traction machine during long-term operation.

[0018] 3. The shock absorption device consists of a rubber spring, an anti-tipping device, and an anti-failure device. The anti-tipping device allows the mounting base to move flexibly in the vertical direction and, passing through the mounting base and the rubber spring, can prevent tipping after the rubber spring fails. The anti-failure device does not affect the vibration damping effect of the rubber spring. When the rubber spring fails, the anti-failure device temporarily supports the mounting base, providing safety protection. Attached Figure Description
