Description

Technical Field

[0001] This utility model relates to a shock-absorbing structure for an upper beam, and more particularly to a shock-absorbing structure for an elevator upper beam. Background Technology

[0002] A vertical elevator is an elevator system capable of transporting people or goods vertically. It typically consists of an elevator shaft, an elevator car, a guide rail system, a drive system, and a control system. The elevator car top is the top structure of the elevator car, and the car itself is the component that carries passengers or other loads; it is the box-shaped space used by the elevator to carry and transport people and goods. Currently, the upper beam and pulley beam are usually connected directly using bolts. During elevator operation, vibrations significantly impact the pulleys, affecting their lifespan. Utility Model Content

[0003] The purpose of this invention is to provide a shock-absorbing structure for the upper beam. It has a better shock absorption effect, reducing the impact of vibration on the rope pulley.

[0004] The technical solution of this utility model is as follows: A shock-absorbing structure for an upper beam includes two sets of opposing upper beams. The two ends of the upper beams are connected by connectors, and a wheel beam is provided inside the upper beam through a shock-absorbing mechanism. The shock-absorbing mechanism includes a first shock-absorbing pad located at both ends of the wheel beam, between the upper beam and the wheel beam. A second shock-absorbing pad corresponding to the first shock-absorbing pad is provided on the outer side of the upper beam. The second shock-absorbing pad has a positioning hole, and the positioning hole has screws and nuts for locking the upper beam and the wheel beam.

[0005] In the aforementioned upper beam with shock absorption structure, the first shock absorption pad is a shock absorption pad with a circular cross-sectional shape, and a circular assembly hole is provided in the middle of the first shock absorption pad.

[0006] In the aforementioned upper beam with damping structure, the second damping pad includes a base part located on the outer side of the upper beam, a mating part coaxially arranged on one side of the base part and corresponding to the assembly hole, and a positioning hole arranged coaxially with the base part and the mating part.

[0007] In the aforementioned installation structure with a damping structure on the upper beam, the upper beam includes a through hole corresponding to the docking part.

[0008] Compared with the prior art, the present invention has the following advantages:

[0009] This application achieves vibration damping between the wheel beam and the upper beam by setting a first damping pad and a second damping pad. One end of the second damping pad can be engaged in the first damping pad, making the positioning more accurate. When locked by screws and nuts, the offset can be reduced, resulting in better reliability. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of the structure of this utility model.

[0012] The markings in the attached diagram are as follows: 1-upper beam, 2-connector, 3-wheel beam, 4-first shock absorber, 5-second shock absorber, 6-positioning hole, 7-screw, 8-nut, 9-assembly hole, 10-through hole, 5.1-base part, 5.2-butt joint part. Detailed Implementation

[0013] Example. A beam-mounted damping structure, configured as follows: Figure 1-2 As shown, the system includes two sets of opposing upper beams 1, with the two ends of the upper beams 1 connected by connectors 2. A wheel beam 3 is provided inside the upper beams 1 through a shock-absorbing mechanism. The shock-absorbing mechanism includes a first shock-absorbing pad 4 located at both ends of the wheel beam 3, between the upper beams 1 and the wheel beam 3. A second shock-absorbing pad 5 corresponding to the first shock-absorbing pad 4 is provided on the outer side of the upper beams 1. The second shock-absorbing pad 5 is provided with a positioning hole 6, and a screw 7 and a nut 8 are provided in the positioning hole 6 for locking the upper beams 1 and the wheel beam 3.

[0014] The first shock-absorbing pad 4 is a shock-absorbing pad with a circular cross-sectional shape, and a circular assembly hole 9 is provided in the middle of the first shock-absorbing pad 4.

[0015] The second shock-absorbing pad 5 includes a base portion 5.1 located outside the upper beam 1. A mating portion 5.2 is provided on one side of the base portion 5.1 and is coaxially arranged and corresponds to the assembly hole 9. A positioning hole 6 is provided in the base portion 5.1 and the mating portion 5.2 and is coaxially arranged with the base portion 5.1 and the mating portion 5.2.

[0016] The upper beam 1 is provided with a through hole 10 corresponding to the docking part 5.2.

[0017] The working principle of this utility model is as follows: During installation, the first shock absorber 4 is placed between the upper beam 1 and the wheel beam 3, and the mounting hole 9 of the first shock absorber 4 corresponds to the position of the through hole 10 in the upper beam 1. Then, the mating part 5.2 of the second shock absorber 5 is inserted into the mounting hole 9 of the first shock absorber 4 to achieve mating, and is locked by bolts 7 and nuts 8. At this time, the base part 5.1 of the second shock absorber 5 is located outside the upper beam 1, thereby achieving a better shock absorption effect. Furthermore, one end of the second shock absorber can be engaged in the first shock absorber, making the positioning more accurate. When locked by screws 7 and nuts 8, the offset can be reduced, resulting in better reliability.
