Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, specifically relating to a compact elevator drive mechanism suitable for confined spaces. Background Technology

[0002] The elevator industry refers to a comprehensive sector encompassing multiple aspects such as elevator design, research and development, manufacturing, installation, maintenance, and after-sales service. As an indispensable vertical transportation tool in modern buildings, elevators are widely used in residential buildings, commercial buildings, public facilities, and industrial plants, covering various types including passenger elevators, freight elevators, escalators and moving walkways, sightseeing elevators, and medical elevators.

[0003] Existing compact elevator drive mechanisms mostly adopt worm gear transmission structures, which are compact in structure, have good self-locking performance, and can adapt to the needs of confined spaces. However, their transmission components are often exposed to the outside, making them susceptible to external interference that can affect normal operation or even damage them, leading to drive failure and safety hazards. Therefore, a compact elevator drive mechanism suitable for confined spaces is needed to solve the above problems. Utility Model Content

Four mounting bolts are inserted into the interior of the mounting base. A support column is fixedly connected to the top of the mounting base. A motor is fixedly connected to the top of the support column. A limit ring is fixedly connected to one side surface of the motor. A worm gear is fixedly connected to the output end of the motor.

[0006] By setting up the above structure, the first and second protective shells are connected by combined bolts to form a sealed space, which can enclose the worm gear transmission structure, creating a stable operating environment for it and effectively isolating it from external dust, moisture and other interference. At the same time, the protective ring protects the heat dissipation fins below throughout the process, preventing them from being damaged by external forces as much as possible. The heat dissipation mesh can block the intrusion of impurities, and at the same time, the heat dissipation through the mesh holes, together with the heat dissipation fins, can increase the heat dissipation area and achieve rapid heat dissipation. In addition, the staff can check the operating status of the transmission structure in real time through the observation window to ensure that the drive mechanism operates safely and stably in the confined space.

[0012] Through the observation window and the combination bolts, staff can observe the operating status of the worm gear drive structure in real time and determine if there are any abnormalities. During maintenance, the protective shell can be opened by disassembling the combination bolts for repair and replacement. The two work together to ensure convenient monitoring and efficient maintenance, giving the drive mechanism good maintainability in a confined space.

A first protective shell 16 is provided, and a second protective shell 17 is provided on top of the first protective shell 16. Two combination bolts 18 are inserted and connected inside the second protective shell 17. An observation window 19 is fixedly connected to the top of the second protective shell 17. The inner walls of the four heat dissipation holes 20 are respectively fixedly connected to the intercepting heat dissipation mesh 21, and the inner walls of the four heat dissipation holes 20 are respectively fixedly connected to the heat dissipation fins 22.

At the same time, the protective ring 23 protects the heat dissipation fins 22 below throughout the process, so that they are as far as possible from external force damage. The intercepting heat dissipation mesh 21 can block the intrusion of impurities, and at the same time, it can dissipate heat through the mesh holes. In conjunction with the heat dissipation fins 22, it can increase the heat dissipation area and achieve rapid heat dissipation. In addition, the staff can check the operating status of the transmission structure in real time through the observation window 19 to ensure that the drive mechanism operates safely and stably in a confined space.

[0024] Multiple fixing bolts 12 are inserted and connected to the fixing flange 11 and the second connecting wheel 13 respectively.

[0029] Working principle and usage process of this utility model:

[0030] After the elevator drive mechanism is fixed by the mounting base 1 and mounting bolts 2, the motor 4 starts and drives the worm gear 6 to rotate. The worm gear 6 meshes with the worm wheel 7 to make it rotate. The worm wheel 7 drives the second connecting wheel 13 and the traction sheave 14 to rotate through the first connecting wheel 8, the combined connecting rod 10, the fixed flange 11 and the fixed bolts 12. This drives the traction steel wire rope 15 wound on the traction sheave 14 to lift the elevator car. During operation, the first protective shell 16 and the second protective shell 17 seal and wrap the worm wheel 7 and worm gear 6 transmission mechanism with the combined bolts 18 to isolate it from the outside world and create a stable operating environment. The protective ring 23 can protect the heat dissipation fins 22 below and prevent them from being damaged by external forces. The heat interception mesh 21 on the first protective shell 16 and the second protective shell 17 can not only block the intrusion of impurities, but also dissipate the heat generated by the transmission structure through the mesh holes. Together with the heat dissipation fins 22, the heat dissipation area is increased to achieve rapid heat dissipation. In addition, the staff can check the operating status of the transmission structure in real time through the observation window 19 so as to judge its working condition in time, thereby ensuring the safe and stable operation of the drive mechanism in a confined space.
