Description

Technical Field

[0001] This utility model relates to the field of traction machine installation technology, and in particular to a vibration reduction and noise reduction structure for an elevator traction machine base. Background Technology

[0002] The elevator traction machine is the core drive unit of an elevator. Its main function is to drive the car and counterweight to move up and down by driving steel wire ropes, thus realizing the elevator's lifting and lowering operation. Its performance directly affects the elevator's safety, stability, operating efficiency, and ride comfort. The base is the basic load-bearing component of the traction machine. Its core function is to fix and support all the core components of the traction machine and coordinate the connection between the traction machine and the overall elevator structure. The traction machine will generate vibrations during operation. The vibration damping device of the base can absorb some of the vibration energy through elastic deformation, reduce the vibration frequency, reduce the noise impact on the machine room, hoistway, and car, and improve ride comfort.

[0003] Traction machines generate low-frequency vibrations and air noise during operation. If the machine room is adjacent to a noise-sensitive area, a vibration damping and noise reduction structure for the elevator traction machine base is required to control the interference. The core components of existing vibration damping and noise reduction structures for elevator traction machine bases are usually installed between the traction machine base and the machine room floor slab, completely covered by the main body of the base. Moreover, the machine room space is small. When maintenance is required, maintenance personnel need to enter the machine room to manually add lubricating oil and perform maintenance. Therefore, the interval between maintenance is often long. If the elevator traction machine operates for a long time without lubrication, dry friction will occur at the gear meshing points and bearings, which will generate noise. The noise will increase with the increase of load, leading to increased mechanical friction, accelerated wear of parts, and a series of chain failures. In severe cases, it may endanger the safe operation of the elevator. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a vibration reduction and noise reduction structure for the elevator traction machine base. It aims to improve the problem that in the prior art, when the elevator traction machine operates for a long time without the use of lubricating oil, dry friction occurs at the gear meshing point and bearing, which in turn generates noise. The noise increases with the increase of load, which leads to increased mechanical friction and accelerated wear of components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vibration reduction and noise reduction structure for an elevator traction machine base, comprising a liquid dispenser, a clamp fixedly connected to the top of the liquid dispenser, a liquid pipe connected to the top of the clamp, a liquid outlet connected to the bottom of the liquid pipe, multiple fixed shafts fixedly connected to the inner wall of the liquid outlet, transmission springs fixedly connected to the outer walls of the multiple fixed shafts, a ball fixedly connected to the bottom of the transmission springs, an outlet shaft connected to the inner wall of the liquid dispenser, a motor fixedly connected to the top of the outlet shaft, a liquid pipe connected to the rear end of the motor, a liquid storage tank connected to the left end of the liquid pipe, and a shock-absorbing mechanism fixedly connected to the bottom of the liquid dispenser, the shock-absorbing mechanism being used to reduce the vibration generated during the operation of the traction machine.

[0006] As a further description of the above technical solution:

[0007] The shock-absorbing mechanism includes a platform, the top of which is fixedly connected to the bottom of the liquid dispenser. Multiple female rotating shafts are fixedly connected to the right side of the top of the platform. Each female rotating shaft has a screw threaded onto its inner wall, and a male rotating shaft is threaded onto the outer wall of each screw. A base is fixedly connected to the top of the male rotating shaft, and a nut is threaded onto the left side of the outer wall of each screw. Multiple air springs are fixedly connected to the bottom of the platform, and a retainer is fixedly connected to the bottom of each air spring. A pneumatic cylinder is fixedly connected to the bottom of the retainer.

[0008] As a further description of the above technical solution:

[0009] A fixing block is fixedly connected to the bottom of the air cylinder, and the outer wall of the male shaft is rotatably connected to the inner wall of the female shaft.

[0010] As a further description of the above technical solution:

[0011] The bottom of the fixing block is fixedly connected to a base, and rubber pads are fixedly connected to the left and right sides of the bottom of the base.

[0012] As a further description of the above technical solution:

[0013] A controller is fixedly connected to the front side of the motor, and the controller is electrically connected to the motor.

[0014] As a further description of the above technical solution:

[0015] A sensor light is fixedly connected to the lower front part of the motor, and a base is fixedly connected to the bottom of the liquid storage tank.

[0016] As a further description of the above technical solution:

[0017] The bottom of the motor is fixedly connected to multiple support legs, and the bottom of the multiple support legs is fixedly connected to the outer wall of the liquid dispenser.

[0018] As a further description of the above technical solution:

[0019] A nameplate is provided on the front side of the liquid dispenser, and multiple screws are threaded onto the inner wall of the nameplate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the parts on the elevator traction machine are not maintained for a long time, the noise generated during the operation of the traction machine will increase. At this time, the operator needs to start the motor and transfer the lubricating fluid in the storage tank to the parts that need lubrication through the fluid dispenser. When the lubricating fluid is driven to flow out, the gravity of the liquid will press the ball, stretch the spring, and squeeze the ball out of the outlet. The lubricating fluid will flow out smoothly. When the motor is stopped, there is no pressure from the gravity of the liquid, and the ball will bounce back into the outlet through the spring to prevent the lubricating fluid from leaking and causing blockage inside the outlet.

[0022] 2. In this utility model, the elevator traction machine is installed on the base. When the base is started, vibration will be generated. Under the action of the air spring and the air cylinder, the elevator traction machine will be damped. When the installation platform is not completely level, the vibration generated by the elevator traction machine will be greater. At this time, we adjust the base to a level position by rotating the male shaft head, and then turn the screw one to tightly engage the screw one with the nut. This fixes the male shaft head and the female shaft head, ensuring that the elevator traction machine will not tilt due to vibration during operation, thus preventing greater noise.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 An embodiment of this utility model provides a vibration reduction and noise reduction structure for an elevator traction machine base, including a liquid filler 1. A clamp 3 is fixedly connected to the top of the liquid filler 1. A liquid pipe 4 is connected to the top of the clamp 3. An outlet 5 is connected to the bottom of the liquid pipe 4. Multiple fixed shafts 7 are fixedly connected to the inner wall of the outlet 5. A transmission spring 9 is fixedly connected to the outer wall of each of the multiple fixed shafts 7. A ball 10 is fixedly connected to the bottom of the transmission spring 9. An outlet shaft 8 is connected to the inner wall of the liquid filler 1. A motor 6 is fixedly connected to the top of the outlet shaft 8. A liquid pipe 11 is connected to the rear end of the motor 6. A storage tank 12 is connected to the left end of the liquid pipe 11. An anti-vibration mechanism 2 is fixedly connected to the bottom of the liquid filler 1. The anti-vibration mechanism 2 is used to reduce the vibration generated during the operation of the traction machine.

[0033] Specifically, the lubricant dispenser 1 plays a crucial role in accurately delivering lubricant to the parts of the elevator traction machine that require lubrication. The clamp 3 is securely fixed to the top of the dispenser 1, and its top end is tightly connected to the liquid pipe 4. The clamp 3 serves to connect and fix the lubricant, ensuring a firm and reliable connection between the liquid pipe 4 and the dispenser 1, preventing lubricant leakage during delivery. The liquid pipe 4 guides the lubricant from the dispenser 1 to the outlet 5. The outlet 5 is the key part where the lubricant flows out; its inner wall is fixedly connected to multiple fixed shafts 7, which are evenly distributed within the outlet 5. Each fixed shaft 7 has a transmission spring 9 fixedly connected to its outer wall, and the bottom end of the transmission spring 9 is connected to a ball 10. The ball 10... Under the action of spring 9, the ball 10 can move flexibly up and down within the outlet 5, which plays a role in controlling the flow of lubricating fluid. When there is lubricating fluid, the ball 10 will be pressed down by the gravity of the lubricating fluid, allowing the lubricating fluid to flow out smoothly. When there is no lubricating fluid, the ball 10 will return to its original position under the elastic force of the transmission spring 9, preventing the lubricating fluid from flowing back and leaking. The rear end of the motor 6 is connected to the liquid pipe 11, and the left end of the liquid pipe 11 is connected to the storage tank 12. The storage tank 12 is a storage container for lubricating fluid. It can hold a sufficient amount of lubricating fluid to meet the needs of the elevator traction machine for long-term operation. The liquid pipe 11 is responsible for transporting the lubricating fluid in the storage tank 12 to the liquid feeder 1, ensuring that the lubricating fluid can be continuously and stably supplied.

[0034] Please see the appendix Figure 2 Appendix Figure 5 and attached Figure 6 The shock-absorbing mechanism 2 includes a platform 202, the top of which is fixedly connected to the bottom of the liquid dispenser 1. Multiple female shafts 204 are fixedly connected to the top right side of the platform 202. Screws 208 are threadedly connected to the inner walls of the multiple female shafts 204. Male shafts 207 are threadedly connected to the outer walls of the screws 208. A base 201 is fixedly connected to the top of the male shafts 207. A nut 209 is threadedly connected to the left side of the outer wall of the screws 208. Multiple air springs 206 are fixedly connected to the bottom of the platform 202. A retainer 205 is fixedly connected to the bottom of the multiple air springs 206. A pneumatic cylinder 203 is fixedly connected to the bottom of the retainer 205.

[0035] Specifically, the top of the platform 202 is firmly fixed to the bottom of the liquid dispenser 1. This connection method ensures that the liquid dispenser 1 can be stably placed on the anti-vibration mechanism 2, so that the lubrication system and the shock absorption system are organically combined to jointly serve the normal operation of the elevator traction machine. Multiple rotating shaft female heads 204 are fixedly connected to the top right side of the platform 202. They are evenly distributed on the platform 202, can withstand a certain force, and ensure the stability of the connection. The inner walls of the multiple rotating shaft female heads 204 are threaded with screws 2. 08. The outer wall of screw 208 is threaded with a male shaft head 207. This threaded connection allows the male shaft head 207 to rotate and be adjusted relative to the female shaft head 204. By rotating screw 208, the position and angle of the male shaft head 207 can be precisely controlled, thereby achieving fine-tuning of the base 201. The top of the male shaft head 207 is fixedly connected to the base 201, which is the installation platform for the elevator traction machine. A nut 209 is threaded onto the left side of the outer wall of screw 208. After the base 201 is adjusted to the appropriate position, tightening the nut 209 can further fix the relative position of the screw 208 and the male shaft 207, preventing the connection from loosening due to vibration during the operation of the traction machine, and ensuring the stability and reliability of the entire adjustment structure. Multiple air springs 206 are fixedly connected to the bottom of the platform 202. When the elevator traction machine vibrates during operation, the platform 202 will transmit the vibration to the air springs 206. The air springs 206 absorb and disperse the vibration energy through the compression and expansion of the internal air, thereby reducing the impact of vibration on the equipment above. The bottom of the multiple air springs 206 is fixedly connected to the fixture 205. The fixture 205 plays the role of concentrating and fixing the air springs 206, integrating the force of multiple air springs 206 together and transmitting it to the air pressure cylinder 203 below. The bottom of the fixture 205 is fixedly connected to the air pressure cylinder 203. The air pressure cylinder 203 and the air springs 206 cooperate with each other to further enhance the shock absorption effect by adjusting the internal air pressure.

[0036] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 A fixing block 20 is fixedly connected to the bottom of the air cylinder 203. The outer wall of the male shaft 207 is rotatably connected to the inner wall of the female shaft 204. A base 15 is fixedly connected to the bottom of the fixing block 20. Rubber pads 14 are fixedly connected to the left and right sides of the bottom of the base 15. A controller 21 is fixedly connected to the front of the motor 6. The controller 21 is electrically connected to the motor 6.

[0037] Specifically, the bottom of the air cylinder 203 is fixedly connected to the fixing block 20. The fixing block 20 plays a key transitional connection role in the entire anti-vibration mechanism 2. The bottom of the fixing block 20 is fixedly connected to the base 15. The base 15 is the direct contact component between the anti-vibration mechanism 2 and other installation foundations. Rubber pads 14 are fixedly connected to the left and right sides of the bottom of the base 15. When vibration is transmitted to the base 15, the rubber pads 14 will undergo elastic deformation, absorbing and consuming some vibration energy, thereby further reducing the vibration transmitted to the ground and reducing noise generation. The outer wall of the male shaft 207 is rotatably connected to the inner wall of the female shaft 204. This rotatable connection provides great flexibility for the adjustment of the base 201. When installing the elevator traction machine, since the installation platform may have a certain degree of tilt and unevenness, by rotating the male shaft 207, the levelness and angle of the base 201 can be precisely adjusted so that the traction machine can be in the best operating state.

[0038] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 A sensor light 13 is fixedly connected to the lower front side of the motor 6. A base 16 is fixedly connected to the bottom of the liquid storage tank 12. Multiple support legs 19 are fixedly connected to the bottom of the motor 6. The bottom of the multiple support legs 19 is fixedly connected to the outer wall of the liquid dispenser 1. A nameplate 18 is provided on the front side of the liquid dispenser 1. Multiple screws 17 are threadedly connected to the inner wall of the nameplate 18.

[0039] Specifically, the sensor light 13 is fixedly connected to the lower front of the motor 6. When the motor 6 malfunctions or operates abnormally, the sensor light 13 can emit warning signals by flashing and changing color to remind the staff to pay attention to the equipment status. The multiple support legs 19 are fixedly connected to the bottom of the motor 6 to ensure that it will not deform or be damaged under the long-term weight and vibration of the motor 6. The base 16 is fixedly connected to the bottom of the liquid storage tank 12 to provide a stable support platform for the liquid storage tank 12. The nameplate 18 is set on the front of the liquid dispenser 1. The multiple screws 17 connected to the inner wall of the nameplate 18 are used to firmly fix the nameplate 18 to the front of the liquid dispenser 1 to prevent the nameplate 18 from loosening, falling off or deforming during use, and to ensure that the information on the nameplate 18 can be clearly and permanently displayed.

[0040] Working principle: First, the operator starts the motor 6. Driven by the power generated by the motor 6, the lubricating fluid flows along specific pipes 4 and 11, eventually entering the dispenser 1. When the lubricating fluid enters the dispenser 1 and flows out, it passes through the outlet 5. Inside the outlet 5, multiple fixed shafts 7 are evenly distributed. Each fixed shaft 7 is fixedly connected to a transmission spring 9, and the bottom end of the transmission spring 9 is connected to a ball 10. When the lubricating fluid flows out, its own weight exerts downward pressure on the ball 10. This pressure overcomes the elasticity of the transmission spring 9, causing the transmission spring 9 to stretch and simultaneously squeezing the ball 10 out of the outlet 5. The lubricant can flow smoothly from the outlet 5 and accurately reach the surface of the traction machine parts that need lubrication, forming a lubricating film, reducing friction between parts, and thus reducing noise. When maintenance is completed and the motor 6 needs to be stopped, the lubricant stops flowing, and there is no gravity squeezing of the liquid. At this time, the transmission spring 9 will use its own elastic restoring force to pull the ball 10 back into the outlet 5, preventing the lubricant from leaking when the motor 6 stops working, avoiding waste of lubricant and environmental pollution. It can also effectively prevent the outlet 5 from being blocked due to lubricant residue, ensuring the normal operation of the lubrication system and the reliability of the next use.

[0041] Then, the elevator traction machine is installed on the base 201. When the traction machine on the base 201 is started, various forces generated during the operation of the traction machine will inevitably cause vibration of the base 201. To solve this problem, an air spring 206 and a pneumatic cylinder 203 are introduced into the design of the base 201. The pneumatic cylinder 203 works in conjunction with the air spring 206 to further enhance the vibration reduction effect by adjusting the internal air pressure. The vibration generated by the elevator traction machine during operation can be significantly reduced, ensuring the smooth operation of the elevator. However, in the actual installation process, due to various factors, the installation platform may not be able to guarantee a completely level position, causing the center of gravity of the traction machine to shift, resulting in vibrations between various components. Uneven force distribution exacerbates vibration and noise generation. Therefore, multiple female shafts 204 are fixedly connected to the top right side of the platform 202. Each female shaft 204 has a screw 208 threaded to its inner wall, and a male shaft 207 is threaded to its outer wall. A nut 209 is also threaded to the left side of the outer wall of the screw 208. When the installation platform is found to be uneven, maintenance personnel can adjust the angle of the base 201 by rotating the male shaft 207. After the base 201 is adjusted to a horizontal position, the screw 208 is then turned to tightly engage the screw 208 and the nut 209, ensuring that the base 201 will not tilt due to vibration during the operation of the traction machine, thus preventing greater noise.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
