Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an elevator traction machine base. Background Technology

[0002] As an indispensable vertical transportation tool in modern high-rise buildings, the stable operation of the elevator's core component, the traction machine, is crucial. The elevator traction machine is the key power source that drives the elevator car to move up and down. It mainly consists of a traction sheave, a motor, and a brake. It is connected to the car and counterweight via steel wire ropes, and the rotation of the traction sheave drives the car to move up and down, realizing the transportation of people or goods.

[0003] Traditional elevator traction machine bases typically use a rigid connection method, usually fixing the base directly to the building structure with bolts, and then fixing the traction machine to the base. In terms of vibration reduction, due to the lack of an effective buffer structure, the vibrations generated by the traction machine during operation are directly transmitted to the building structure along the base. Over time, this not only increases elevator operating noise but may also cause local loosening of the building structure, affecting the overall stability of the building.

[0004] Traditional elevator bases lack automatic oiling functions for wire rope lubrication and maintenance. During prolonged elevator operation, the wire ropes frequently rub against the traction sheave. If lubricating oil is not replenished in time, the wire ropes are prone to wear and rust, reducing their service life and potentially causing wire breakage during operation, seriously endangering elevator safety. Furthermore, routine maintenance requires manual intervention by periodically climbing to the traction machine to apply oil to the wire ropes. This process is cumbersome, time-consuming, and labor-intensive, and it's difficult to accurately control the amount of oil applied, easily leading to oil waste or insufficient lubrication. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to propose an elevator traction machine base that can effectively reduce the vibration generated during the operation of the elevator traction machine and enable automatic oiling of the steel wire rope on the elevator traction machine, effectively meeting the actual usage needs of the elevator traction machine and possessing strong practicality.

[0006] The technical solution of this utility model is achieved as follows: an elevator traction machine base, including a base body, a bearing base, an air spring shock absorber, and an oiling device;

[0007] The supporting base is disposed above the base body;

[0008] Several sets of the aforementioned air spring shock absorbers are connected between the seat body and the load-bearing base;

[0009] The elevator traction machine is mounted on the support base;

[0010] The seat and the supporting base are provided with slots for the steel wire rope of the elevator traction machine to pass through;

[0011] The oiling device is mounted on the support base and is used to apply oil to the surface of the wire rope.

[0012] Furthermore, the oiling device includes an oil tank, a metering pump, and an oil spraying component; the first end of the metering pump is connected to the oil tank, and the second end is connected to the oil spraying component; the oil spraying component has an oil nozzle facing the wire rope.

[0013] Furthermore, oil spray nozzles are provided on opposite sides of each of the steel wire ropes.

[0014] Furthermore, the oil injection component is a U-shaped part with a flow channel formed inside; the U-shaped part surrounds the outside of the steel wire rope, and the two extended sides of the U-shaped part extend along the arrangement direction of each steel wire rope; the second end of the metering pump is connected to the flow channel; the oil injection port is disposed on the opposite inner sidewall of the two extended sides of the U-shaped part and is connected to the flow channel.

[0015] Furthermore, the oil tank is equipped with a level gauge for detecting the oil level.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] 1. This utility model, through the combined use of air spring shock absorbers, can effectively buffer the vibrations generated during the operation of the traction machine, preventing the vibrations from being directly transmitted to the building structure. Compared with traditional rigid connection bases, it greatly reduces operating noise, creating a quiet and comfortable elevator environment for passengers, and can also reduce the damage to the building structure caused by long-term vibrations.

[0018] 2. This utility model, through the use of an oiling device, allows multiple oil nozzles on the oil spraying component to precisely target both sides of the wire rope. Combined with a metering pump drawing oil from the oil tank, it can automatically, periodically, and quantitatively apply oil to the wire rope during elevator operation. This ensures the wire rope is always in a well-lubricated state, reducing wear and rust risks and extending its service life. It also eliminates the tedious manual oiling operation of frequent climbing, reducing maintenance costs and improving elevator maintenance efficiency, making it particularly suitable for high-rise buildings with multiple elevators.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] like Figure 1-6 The image shows a base 1 for an elevator traction machine 8 as described in this embodiment, comprising a base body, a load-bearing base 2, air spring shock absorbers 3, and an oiling device. The base 1 has a flat rectangular structure. The four corners of the base body are fixedly connected to the building body by bolts. A set of air spring shock absorbers 3 is fixed at each of the four corners of the base body.

[0029] The support base 2 is positioned above the seat body and connected to the top of the air spring shock absorber 3. The air spring shock absorber 3 provides vibration damping for the support base 2. The elevator traction machine 8 is fixedly mounted on the support base 2 via a bracket 9. A steel wire rope 81 is arranged on the traction sheave of the elevator traction machine 8. Through slots 4 are machined on the support base 2 and the base 1 at positions corresponding to the steel wire rope 81. The steel wire rope 81 of the elevator traction machine 8 moves through these slots 4. The aforementioned oiling device is installed on the support base 2 to apply oil to the surface of the steel wire rope 81. This oiling operation ensures that the surface of the steel wire rope 81 remains lubricated at all times.

[0030] The aforementioned oiling device includes an oil tank 5, a metering pump 6, and an oil spraying component 7. The oil tank 5 is fixedly mounted on the support base 2 to hold lubricating oil. The oil spraying component 7 is arranged corresponding to the wire rope 81 and has an oil spray nozzle 71 facing the wire rope 81. Lubricating oil is sprayed onto the surface of the wire rope 81 through this nozzle 71. The first end of the metering pump 6 is connected to the oil tank 5, and the second end is connected to the oil spraying component 7, enabling it to draw lubricating oil from the oil tank 5 and deliver it to the oil spraying component 7. Oil spray nozzles 71 are arranged on opposite sides of each wire rope 81 to spray oil onto both sides of the wire rope 81. In a specific structural design, the oil spraying component 7 is a U-shaped part with an internal flow channel. The U-shaped part surrounds the outside of the wire rope 81, and its two extending edges extend along the arrangement direction of each wire rope 81. The second end of the metering pump 6 is connected to the flow channel to deliver lubricating oil into the flow channel. Each oil injection port 71 is arranged on the opposite inner sidewall of the two extended sides of the U-shaped part and is connected to the flow channel.

[0031] The oil tank 5 is equipped with a level gauge for detecting the oil level. A filler port is machined onto the top of the oil tank 5, and the filler port is fitted with a sealing cap. The sealing cap contains a rubber sealing ring to prevent dust and impurities from entering.

[0032] In practical use, when the elevator is running, the pneumatic action of the elevator traction machine 8 transmits the vibrations generated to the support base 2. The air spring shock absorbers 3 at the four corners of the support base 2 function, absorbing and buffering the vibration energy through the elastic deformation characteristics of the air springs, preventing direct transmission of vibration to the base body, thus reducing the impact on the building structure and ensuring smooth and quiet operation. For the lubrication and maintenance of the wire rope 81, the metering pump 6 is started and stopped at set times by an external controller. When the preset oiling time or operating cycle is reached, the metering pump 6 starts working. The lubricating oil in the oil tank 5 is pumped by the metering pump 6 and transported through pipelines to the oil spraying component 7. The lubricating oil is precisely sprayed from the oil spray nozzle 71 onto the surface of the wire rope 81 on both sides of the traction sheave, ensuring uniform lubrication of both sides of the wire rope 81. Lubricating oil can be replenished through the oil filler port on the top of the oil tank 5. Dust is prevented by the sealing cap and rubber sealing ring, and the liquid level is checked using a level gauge to ensure the normal operation of the oiling device. Through the above methods, the vibrations generated during the operation of the traction machine can be effectively buffered, preventing direct transmission of vibration to the building structure. Compared to the traditional rigid connection base 1, this design significantly reduces operating noise, creating a quiet and comfortable riding environment for passengers and minimizing damage to the building structure caused by long-term vibration. Multiple oil nozzles 71 on the oil spraying component 7 are precisely oriented towards both sides of the wire rope 81. Working in conjunction with the metering pump 6, oil is drawn from the oil tank 5, automatically, periodically, and quantitatively applying oil to the wire rope 81 during elevator operation. This ensures the wire rope 81 is always well-lubricated, reducing the risk of wear and rust, and extending its service life. The entire process requires no manual operation, achieving automatic oiling and eliminating the tedious manual climbing and oiling operations, thus reducing maintenance costs and improving elevator maintenance efficiency. It is particularly suitable for high-rise buildings with multiple elevators.
