In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or implementations.
[0022] To solve the above problems, an embodiment of the present invention provides an elevator test shaft rubber vibration damping system, comprising a first steel structure 1, a second steel structure 2 and a shock-absorbing component 3, wherein the two first steel structures 1 and the second steel structure 2 are respectively arranged on both sides of a concrete beam 8, and a plurality of the shock-absorbing components 3 are respectively arranged on the corresponding concrete beam 8 and fixedly connected to the first steel structure 1 and the second steel structure 2; each of the shock-absorbing components 3 comprises a rubber pad 4, a first steel plate 5 and a second steel plate 6, and the two rubber pads 4 are respectively arranged on both sides of the current concrete beam 8, and the two ends of the first steel plate 5 are respectively fixedly connected to the first steel structure 1 and the second steel structure 2, and the side surfaces of the first steel plate 5 are respectively in contact with one end of the two rubber pads 4, and the second steel plate 6 is arranged on one side of the other end of the two rubber pads 4, and the two ends of the second steel plate 6 are respectively fixedly connected to the first steel structure 1 and the second steel structure 2.
[0023] It should be noted that if Figures 1 to 3As shown, the two first steel structures 1 and the second steel structure 2 are respectively arranged on both sides of the concrete beam 8 so that the concrete beam 8 can support the two first steel structures 1 and the second steel structure 2. The two first steel structures 1 are respectively arranged on both sides of the second steel structure 2. A plurality of shock-absorbing components 3 are respectively arranged on the concrete beam 8 and fixedly connected to the first steel structure 1 and the second steel structure 2, so that when the elevator is working, the vibration is transmitted to the concrete beam 8 through the two first steel structures 1 and the second steel structure 2 and is buffered by the plurality of shock-absorbing components 3 to reduce the vibration force transmitted to the concrete beam 8. The two rubber pads 4 in each shock-absorbing component 3 are respectively located on both sides of the current concrete beam 8 to fill the gap between the concrete beam 8 and the first steel structure 1 or the second steel structure 2, thereby buffering the vibration force of the two first steel structures 1 and the second steel structure 2. The first steel plate 5 is arranged at one end of the two rubber pads 4, and the second steel plate 6 is arranged at the other end of the two rubber pads 4. The first steel plate 5 and the second steel plate 6 can prevent the rubber pads 4 from slipping out or falling off during use.
[0024] In one embodiment of the present invention, rubber convex strips are respectively provided on both sides of each rubber pad 4 .
[0025] It should be noted that rubber ridges are provided on both sides of each rubber pad 4. The rubber ridges can increase the friction between the rubber pad 4 and the surface of the connecting steel plate 7, thereby preventing the rubber pad 4 from sliding or falling off during use. This helps to ensure that the rubber pad 4 remains stable during the filling and fixing process. The presence of the rubber ridges can increase the elasticity of the rubber pad 4 and improve its shock resistance.
[0026] In one embodiment of the present invention, each of the rubber convex strips is arranged in a trapezoidal shape.
[0027] It should be noted that the presence of the rubber ridges can increase the elasticity of the rubber pad 4 and improve its shock resistance. The trapezoidal ridges can more evenly disperse the load on the pad. Through the trapezoidal shape of the ridges, the load can be more evenly distributed over the entire width of the rubber pad 4, helping to reduce local pressure and improve the durability of the pad. This can help slow down the wear of the rubber pad 4 and increase its service life.
[0028] In one embodiment of the present invention, Figure 3 As shown, each of the shock absorbing components 3 further includes a connecting steel plate 7 , two of the connecting steel plates 7 are respectively arranged on the side of each of the rubber pads 4 , and a steel plate convex strip is provided on the side of each of the connecting steel plates 7 close to the rubber pad 4 .
[0029] It should be noted that by adjusting the thickness of the connecting steel plate 7, which is arranged between the rubber pad 4 and the first steel structure 1 or the second steel structure 2, it should be squeezed tightly to ensure that the rubber pad 4 does not fall off during use. The steel plate ridges can increase the contact area between the connecting steel plate 7 and the rubber pad 4, thereby increasing friction and stability.
[0030] In one embodiment of the present invention, an anti-corrosion coating is provided on the surface of each of the first steel plate 5 , the second steel plate 6 and the connecting steel plate 7 .
[0031] It should be noted that an anti-corrosion coating is applied on the surface of each first steel plate 5, second steel plate 6 and connecting steel plate 7 to ensure that the surface can be prevented from being corroded by moisture, oxygen and chemicals in the atmosphere when welding is adopted at the connection. This helps to extend the service life, especially in humid or corrosive environments. The anti-corrosion coating helps to maintain the structural stability of each first steel plate 5, second steel plate 6 and connecting steel plate 7. By preventing corrosion, the coating can ensure that its designed strength and rigidity are maintained, thereby maintaining the stability of the entire structure.
[0032] In one embodiment of the present invention, the anti-corrosion coating is epoxy resin coating.
[0033] It should be noted that epoxy resin coatings are highly resistant to many chemicals, acids, bases, and solvents. This allows them to effectively protect substrates in environments subject to corrosive attack. Epoxy resin coatings also have a high hardness and excellent wear resistance, which helps to increase friction between each of the first steel plate 5, the second steel plate 6, and the connecting steel plate 7, thereby reducing wear.
[0034] In one embodiment of the present invention, two first steel structures 1 are arranged side by side, and each of the first steel structures 1 includes a first crossbeam and a first steel column. Both ends of a plurality of first crossbeams respectively pass through a plurality of first steel columns and are fixedly connected.
[0035] It should be noted that the two first steel structures 1 arranged side by side can increase the stability of the overall structure. By connecting multiple beams and multiple steel columns, the load can be effectively shared and transmitted. The two ends of the multiple first beams are fixedly connected to the inner wall of the test well.
[0036] In one embodiment of the present invention, the second steel structure 2 includes second steel columns and second beams, and a plurality of second beams are respectively arranged between four second steel columns.
[0037] It should be noted that the arrangement of multiple beams can improve the seismic performance of the structure, helping to support the elevator and disperse and bear vertical and horizontal loads, thereby improving the stability of the overall structure. The connection method and layout of the beams can help to slow down vibrations and disperse energy when impacts generated during elevator operation occur, thereby reducing the possibility of damage.
[0038] It should be noted that the above-described embodiments of the present invention do not limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
