Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an easily replaceable MC nylon elevator drive wheel. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving on at least two rigid tracks perpendicular to the horizontal plane or with an angle of inclination to the vertical of less than 15 degrees. A Chinese utility model patent, authorized announcement number "CN215828129U", discloses a friction-type nylon elevator drive wheel, including a rotating shaft. A transmission device is movably mounted on the outside of the rotating shaft. The transmission device includes a wheel blade, a fixed frame, a fixed screw, a first screw, a first nut, and a second screw. The wheel blade is movably mounted on the outside of the rotating shaft. The right side of the wheel blade is threadedly connected to the fixed frame. The right side of the fixed frame is threadedly connected to four fixed screws. Four first screws are movably mounted inside the wheel blade. This friction-type nylon elevator drive wheel has four blades that fit together. A first screw passes through each blade and a first nut secures the blades. This allows the blades to be installed one by one during installation, reducing the weight of the blades themselves. In daily maintenance, if one blade malfunctions, only the faulty blade needs to be replaced, avoiding waste of the drive wheel.

[0003] The above technical solution uses four blades that fit together, with a first screw passing through each blade and a first nut securing them. This allows the blades to be installed one by one during installation. However, this solution still has certain drawbacks. For example, while the first screw passes through each blade and the first nut secures them, allowing for individual installation, the connection between the blades and the shaft is not protected. This allows dust, impurities, and dirt to easily enter the connection, increasing friction, accelerating wear, and ultimately causing wear on the contact surface between the blades and the shaft, shortening the lifespan of the components and increasing the replacement frequency. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an easily replaceable MC nylon elevator drive wheel. This solves the problem that the equipment uses a first screw to pass through each wheel blade and a first nut to fix the wheel blades, allowing the wheel blades to be installed one by one during the installation process. However, the connection between the wheel blade and the shaft is not protected, which allows dust, impurities and dirt to easily enter the connection between the wheel blade and the shaft. These foreign objects will increase friction, accelerate the wear of the parts, and thus cause the contact surface between the wheel blade and the shaft to be easily worn, shortening the service life of the parts and increasing the replacement frequency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A replaceable MC nylon elevator drive wheel, comprising a mounting shaft and three second MC nylon drive wheels, wherein protective devices are provided at both ends of the mounting shaft;

[0006] The protective device includes a first MC nylon drive wheel and a dustproof end cap. A groove is opened on the outer wall of one end of the dustproof end cap. Four guide limit blocks are fixedly connected to the inner wall of the first MC nylon drive wheel. Four guide grooves are opened on the outer wall of the mounting shaft. The first MC nylon drive wheel is sleeved on the outer wall of one end of the mounting shaft, and the dustproof end cap is sleeved on the outer wall of one end of the mounting shaft.

[0007] The sleeve groove has four conical blocks fixedly connected inside. The outer wall of one end of the first MC nylon drive wheel has four conical block grooves. The four conical block grooves are all provided with first fixing bolt grooves. The outer wall of the dustproof end cover is threaded with four first fixing bolts. The two protective devices are respectively set at both ends of the mounting shaft.

[0008] Preferably, the outer walls of the four guide limiting blocks are slidably connected to the interior of the corresponding guide grooves, one end of the outer wall of the first MC nylon transmission wheel is slidably connected to the interior of the sleeve groove, and the outer walls of the four conical blocks are slidably connected to the interior of the corresponding conical block grooves.

[0009] Among them, the ends of the four first fixing bolts near the first fixing bolt slots are all threaded into the interior of the tapered block slots and respectively connected to the internal threads of the corresponding first fixing bolt slots.

[0010] Preferably, all three second MC nylon drive wheels are sleeved on the outer wall of the mounting shaft, and the interior of both dustproof end caps is provided with a fixed limiting frame;

[0011] The inner walls of the two fixed limiting frames are slidably connected to the outer walls of the two ends of the mounting shaft, and the inner walls of the three second MC nylon transmission wheels are all fixedly connected with the same four guide limiting blocks.

[0012] Preferably, the outer walls of the two fixed limiting frames are slidably connected to the inner wall of one end of the first MC nylon transmission wheel;

[0013] Among them, the outer walls of the guide limit blocks on the three second MC nylon drive wheels are slidably connected to the interior of the corresponding guide grooves, and four grooves are opened on the inner wall of one end of the two first MC nylon drive wheels.

[0014] Preferably, each of the eight grooves has a second fixing bolt groove inside, and the outer walls of the four protrusions on the two fixing limit frames are slidably connected to the inside of the corresponding grooves.

[0015] Among them, the outer wall of the two first MC nylon drive wheels away from the dustproof end cover is in close contact with the outer wall of the corresponding second MC nylon drive wheel on one side, and the outer walls of the four protrusions on the two fixed limit frames are threaded with second fixing bolts.

[0016] Preferably, the ends of the eight second fixing bolts near the second fixing bolt slots are all threaded into the interior of the grooves and respectively connected to the internal threads of the corresponding second fixing bolt slots;

[0017] Among them, the outer wall of the two fixed limiting frames near the mounting shaft is in contact with the outer walls of the two ends of the mounting shaft.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The easily replaceable MC nylon elevator drive wheel protects the connection between the first MC nylon drive wheel and the mounting shaft through the dustproof end cover in the protective device. This effectively prevents dust, impurities, and dirt from entering the connection between the drive wheel and the shaft, keeping the interior clean. This reduces friction at the connection while improving the service life of both the second and first MC nylon drive wheels. Attached Figure Description

[0031] Please see Figure 1-5 This utility model provides a technical solution: an easily replaceable MC nylon elevator drive wheel, including a mounting shaft 1 and three second MC nylon drive wheels 4;

[0032] Protective devices are provided at both ends of the mounting shaft 1;

[0033] The protective device includes a first MC nylon drive wheel 3 and a dustproof end cap 5. A groove 15 is formed on the outer wall of one end of the dustproof end cap 5. Four guide limiting blocks 14 are fixedly connected to the inner wall of the first MC nylon drive wheel 3. Four guide grooves 11 are formed on the outer wall of the mounting shaft 1. The first MC nylon drive wheel 3 is sleeved on the outer wall of one end of the mounting shaft 1. The outer walls of the four guide limiting blocks 14 are slidably connected to the interior of their respective guide grooves 11. The dustproof end cap 5 is sleeved on the outer wall of one end of the mounting shaft 1. The outer wall of one end of the first MC nylon drive wheel 3 is slidably connected to the interior of the groove 15. The internal fixed connection has four conical blocks 7. The outer wall of one end of the first MC nylon drive wheel 3 has four conical block grooves 8. The outer walls of the four conical blocks 7 are slidably connected to the interior of the corresponding conical block grooves 8. The interior of each of the four conical block grooves 8 has a first fixing bolt groove 6. The outer wall of the dustproof end cover 5 is threadedly connected to four first fixing bolts 2. The ends of the four first fixing bolts 2 near the first fixing bolt grooves 6 are threaded into the interior of the conical block grooves 8 and are respectively threadedly connected to the interior of the corresponding first fixing bolt grooves 6. The two protective devices are respectively set at both ends of the mounting shaft 1.

[0034] Among them, three second MC nylon drive wheels 4 are all sleeved on the outer wall of the mounting shaft 1. The interior of each of the two dustproof end caps 5 is provided with a fixed limiting frame 10. The inner walls of the two fixed limiting frames 10 are slidably connected to the outer walls of both ends of the mounting shaft 1. The inner walls of each of the three second MC nylon drive wheels 4 are fixedly connected with four identical guide limiting blocks 14. The outer walls of the two fixed limiting frames 10 are slidably connected to the inner wall of one end of the first MC nylon drive wheel 3. The outer walls of the guide limiting blocks 14 on the three second MC nylon drive wheels 4 are slidably connected to the interior of the corresponding guide grooves 11. Each of the two first MC nylon drive wheels 3 has four grooves 12 on one end of its inner wall. The eight grooves 12... Each of the two fixed limit frames 10 has a second fixing bolt groove 13 inside. The outer walls of the four protrusions on the two fixed limit frames 10 are slidably connected to the interior of the corresponding grooves 12. The outer walls of the two first MC nylon drive wheels 3 away from the dustproof end cover 5 are tightly attached to the outer walls of the corresponding second MC nylon drive wheels 4. The outer walls of the four protrusions on the two fixed limit frames 10 are threaded with second fixing bolts 9. The eight second fixing bolts 9 are threaded to the interior of the grooves 12 at the ends near the second fixing bolt grooves 13 and are threadedly connected to the interior of the corresponding second fixing bolt grooves 13. The outer walls of the two fixed limit frames 10 at the ends near the mounting shaft 1 are in corresponding contact with the outer walls of the two ends of the mounting shaft 1.

[0035] Furthermore, when using this device, the mounting shaft 1 uses external bearings to install the second MC nylon drive wheel 4 and the first MC nylon drive wheel 3 in designated positions. Then, when the elevator receives a running command, the motor starts, and the high-speed rotational power is converted into low-speed, high-torque power suitable for the second MC nylon drive wheel 4 and the first MC nylon drive wheel 3 via a reducer. This allows the second MC nylon drive wheel 4 and the first MC nylon drive wheel 3 to rotate smoothly with the support of the bearings. Simultaneously, the dustproof end cover 5 protects the connection between the first MC nylon drive wheel 3 and the mounting shaft 1, effectively preventing dust, impurities, and dirt from entering the connection between the drive wheel and the shaft, thus maintaining internal cleanliness. When it is necessary to remove the first MC nylon drive wheel 3 or the second MC nylon drive wheel 4, turn the first fixing bolt 2 to rotate it so that the other end of the outer wall of the first fixing bolt groove 6 is disengaged from the inside. Then pull the dustproof end cover 5 to remove it from the mounting shaft 1. Turn the second fixing bolt 9 to rotate it so that the other end of the outer wall is disengaged from the inside of the second fixing bolt groove 13. Then pull the fixing limit frame 10 to remove it from the inside of one end of the first MC nylon drive wheel 3. Then pull the first MC nylon drive wheel 3 to remove it from the mounting shaft 1. Then the second MC nylon drive wheel 4 can be removed from the mounting shaft 1 by pulling it after losing the limit of one end of the first MC nylon drive wheel 3.

[0036] The dustproof end cap 5 in the protective device protects the connection between the first MC nylon drive wheel 3 and the mounting shaft 1, effectively preventing dust, impurities and dirt from entering the connection between the drive wheel and the shaft and keeping the inside clean. This reduces friction at the connection and improves the service life of the second MC nylon drive wheel 4 and the first MC nylon drive wheel 3.

One end is connected to the dustproof end cover 5, and the other end is embedded in the first fixing bolt groove 6, which facilitates quick disassembly and installation of the dustproof end cover 5 and makes maintenance convenient; it is firmly fixed to prevent the dustproof end cover 5 from loosening during operation.

[0039] First MC nylon drive wheel 3: Installed on mounting shaft 1, it works with second MC nylon drive wheel 4 to transmit power. MC nylon material is wear-resistant and shock-absorbing, extending service life; it fits tightly with mounting shaft 1, ensuring smooth transmission.

[0040] The second MC nylon drive wheel 4 is installed at the other end of the mounting shaft 1, opposite to the first MC nylon drive wheel 3, and together they transmit power. The double-sided drive wheel design improves transmission stability; the nylon material reduces the overall weight and energy consumption.

[0041] Dustproof end cap 5: Installed at the connection between the first MC nylon drive wheel 3 and the mounting shaft 1, it serves to prevent dust and impurities from entering, keeping the interior clean. It has a simple design and is easy to disassemble and install.
