The national standard GB / T 10058-2023 "Elevator Technical Conditions" 4.3 Overall performance puts forward clear requirements for indicators that affect the passenger ride quality, such as elevator door opening and closing time, vibration and noise.

[0003] In order to meet and exceed the requirements of the above-mentioned national standards, Chinese patent application number 202023245808.6 discloses a shock-absorbing upper beam device for the top of an organic passenger elevator car, which includes: a car frame upper beam, an upper guard cover, a buffer pad, a reinforced angle steel, a buffer upper beam, a rope stop device, a car top wheel, a U-bolt, and a lower guard cover. The buffer upper beam is connected to the bottom of the car frame upper beam, and a buffer pad is installed between the car frame upper beam and the buffer upper beam. The car top wheel is fixed to the buffer upper beam by U-bolts. The car top wheel is provided with an upper guard cover and a lower guard cover. The upper guard cover and the lower guard cover are respectively connected to the car frame upper beam and the buffer upper beam, and a rope stop device is provided in the middle of the buffer upper beam.

[0004] The machine room passenger elevator car top shock-absorbing upper beam device has rubber shock-absorbing blocks installed between the upper and lower steel plates to absorb the vibration of the car during operation, thereby achieving the requirement of improving the comfort of the elevator. However, the device does not consider the design of preventing the rubber pad from being damaged due to excessive compression due to overload, and also needs to consider the universal installation of the machine room to meet both the rear counterweight and the side counterweight layout. This is the area that the technicians focus on improving. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a universal shock absorbing device for a car top wheel for improving the riding quality of an elevator, which can achieve effective shock absorption of the elevator and ensure its reliability.

[0006] A technical solution to achieve the above object is: a universal car top wheel shock absorbing device for improving the ride quality of an elevator, comprising an upper beam and a car top wheel assembly;

[0007] The upper beam is composed of a first upper beam bent piece and a second upper beam bent piece arranged in parallel, and the two are connected to form an overall structure of the upper beam through a connecting piece. The lower sides of the first upper beam bent piece and the second upper beam bent piece are provided with a bending edge, and a connecting hole is opened on the bending edge;

[0008] The car top wheel assembly includes a shock-absorbing rubber, a shock-absorbing rubber upper cover plate, a shock-absorbing rubber lower cover plate, a car top wheel support frame and a car top wheel. The car top wheel is fixed on the car top wheel support frame. The shock-absorbing rubber upper cover plate and the shock-absorbing rubber lower cover plate respectively cover the upper and lower parts of the shock-absorbing rubber to form a shock-absorbing part. Shock-absorbing parts are arranged on both sides of the top of the car top wheel support frame and are connected to the upper beam by fasteners passing through the connecting holes. A matching gap is left between the shock-absorbing rubber upper cover plate and the shock-absorbing rubber lower cover plate.

[0009] Furthermore, the width of the matching gap between the shock-absorbing rubber upper cover plate and the shock-absorbing rubber lower cover plate is less than or equal to the maximum value of the compression of the shock-absorbing rubber when the elevator is fully loaded.

[0010] Furthermore, the lower side of the first upper beam bent piece is provided with a first connecting hole, a second connecting hole and a third connecting hole at equal intervals, and the lower side of the second upper beam bent piece is provided with a fourth connecting hole, a fifth connecting hole and a sixth connecting hole symmetrically; wherein the first connecting hole, the third connecting hole, the fourth connecting hole and the sixth connecting hole are at equal intervals, forming a square layout.

[0012] Furthermore, the rope blocking rod comprises a side rope blocking rod and a bottom rope blocking rod.

[0013] The utility model discloses a universal shock-absorbing device for a car top wheel for improving the riding quality of an elevator. The shock-absorbing rubber is installed between the car top wheel and the upper beam. When a steel wire rope is wound around the car top wheel and the elevator is subjected to force during passenger operation, the shock-absorbing rubber can absorb vibration during car operation, thereby improving the riding comfort. The shock-absorbing rubber upper cover plate and the shock-absorbing rubber lower cover plate respectively cover the upper and lower parts of the shock-absorbing rubber and are installed between the car top wheel assembly and the upper beam. A certain gap is left between the shock-absorbing rubber upper cover plate and the shock-absorbing rubber lower cover plate. The gap distance is less than or equal to the maximum value of the compression of the shock-absorbing rubber when the elevator is fully loaded. At this time, when the car is overloaded, the shock-absorbing rubber will not continue to be compressed to cause damage. The connecting holes are arranged in a square shape with equal sides. When the counterweight rear layout is switched to the counterweight side layout, the entire shock-absorbing device only needs to be rotated 90 degrees to conveniently complete the installation. The utility model has a universality. BRIEF DESCRIPTION OF THE DRAWINGS
