Description

Technical Field

[0001] This utility model belongs to the technical field of elevator door opening and closing precision positioning device, specifically relating to an elevator door opening and closing precision positioning device. Background Technology

[0002] An elevator door opening and closing precision positioning device is a device used to ensure that elevator doors can accurately and stably stop at a predetermined position during the opening and closing process. Its main function is to monitor the position and status of the elevator door in real time through sensors and a control cabinet, thereby achieving precise positioning.

[0003] The control cabinet of the existing elevator door opening and closing precision positioning device generates heat continuously during operation. It usually relies on the heat dissipation vents for natural heat dissipation. However, due to the uneven layout of the components, the heat dissipation efficiency varies. Some components have poor heat dissipation, which can affect the normal operation and service life of the components. Therefore, an elevator door opening and closing precision positioning device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a precise positioning device for elevator door opening and closing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precise positioning device for elevator door opening and closing, comprising a control cabinet, a cable fixedly connected to one side surface of the control cabinet, a sensor fixedly connected to one end of the cable, a microprocessor fixedly connected inside the control cabinet, an input interface circuit fixedly connected inside the control cabinet, a counter fixedly connected inside the control cabinet, a signal processor fixedly connected inside the control cabinet, a relay fixedly connected inside the control cabinet, a power supply fixedly connected inside the control cabinet, a mounting plate fixedly connected inside the control cabinet, a threaded screw rotatably connected inside the mounting plate, and a drive motor fixedly connected to one end of the threaded screw. A support plate is fixedly connected to the bottom of the drive motor. A threaded hole block is threadedly connected to the surface of the threaded screw. A combination rod is fixedly connected to both sides of the threaded hole block. Two guide grooves are opened inside the mounting plate. The other ends of the two combination rods are fixedly connected to mounting rings. Protective covers are fixedly connected inside the two mounting rings. Drive cooling fans are fixedly connected inside the two mounting rings. Two barrier nets are fixedly connected inside the mounting plate. Two arc-shaped protective rings are fixedly connected to the surface of the mounting plate. Limiting grooves are opened on both sides of the arc-shaped protective rings. Limiting slide plates are slidably connected to the inner walls of the two limiting grooves. Bidirectional scrapers are fixedly connected to the bottoms of the two limiting slide plates.

[0006] By setting up the above structure, not only can a stable power be provided for the dynamic heat dissipation structure, enabling the cooling fan to reciprocate along the guide slide to cover heat-generating components such as the microprocessor, thus solving the heat dissipation dead zone problem of traditional fixed fans as much as possible, but also, through the rigid connection between the screw hole block and the limit slide plate, the bidirectional scraper can be driven to slide synchronously along the limit slide of the arc-shaped protective ring to clean the dust from the barrier net. With the coordinated cooperation of all structures, dynamic heat dissipation and automatic dust removal can be achieved, ensuring that the components inside the control cabinet operate at a suitable temperature and extending the service life of the equipment.

[0007] As a preferred embodiment, the threaded screw rotates inside the control cabinet.

[0008] As a preferred embodiment, one side surface of the support plate is fixedly connected to the top of the control cabinet.

[0009] As a preferred embodiment, the two combined rods slide on the inner wall of the guide groove respectively.

[0010] As a preferred embodiment, the screw hole block slides inside the arc-shaped protective ring.

[0011] As a preferred embodiment, one side surface of each of the two limiting slide plates is fixedly connected to the surface of the screw hole block.

[0012] As a preferred embodiment, the bottoms of the two bidirectional scrapers are respectively attached to the top of the barrier net.

[0013] By setting an arc-shaped protective ring, it can not only protect the transmission structure of the threaded screw and the screw hole block below, but also the two limit slides inside can cooperate with the guide slide to provide limit guidance for the movement of the screw hole block, so that the screw hole block can drive the cooling fan and the bidirectional scraper to move along a precise trajectory, effectively ensuring the heat dissipation and dust cleaning functions of the control cabinet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, through the linkage design of the drive motor and the threaded screw, not only provides stable power for the dynamic heat dissipation structure, enabling the cooling fan to reciprocate along the guide groove and cover heat-generating components such as the microprocessor, thus solving the heat dissipation dead zone problem of traditional fixed fans as much as possible, but also, through the rigid connection between the screw hole block and the limiting slide plate, drives the bidirectional scraper to slide synchronously along the limiting groove of the arc-shaped protective ring to clean the dust from the barrier. With the coordinated cooperation of all structures, dynamic heat dissipation and automatic dust removal can be achieved, ensuring that the components inside the control cabinet operate at a suitable temperature and extending the service life of the equipment.

Mounting rings 17 are fixedly connected to the other ends of the two combination rods 15. The device is equipped with a protective cover 18. Two driving cooling fans 19 are fixedly connected inside the two mounting rings 17. Two barrier nets 20 are fixedly connected inside the mounting plate 10. Two arc-shaped protective rings 21 are fixedly connected to the surface of the mounting plate 10. Limiting grooves 22 are formed on both sides of the arc-shaped protective rings 21. Limiting slide plates 23 are slidably connected to the inner walls of the two limiting grooves 22. Two bidirectional scrapers 24 are fixedly connected to the bottoms of the two limiting slide plates 23. Through the linkage design of the drive motor 12 and the threaded screw 11, it can not only provide dynamic cooling... The thermal structure provides stable power, enabling the cooling fan 19 to reciprocate along the guide slide 16, covering heat-generating components such as the microprocessor 4, thus solving the problem of heat dissipation dead zones in traditional fixed fans as much as possible. At the same time, through the rigid connection between the screw hole block 14 and the limiting slide plate 23, it can drive the bidirectional scraper 24 to slide synchronously along the limiting slide 22 of the arc-shaped protective ring 21 to clean the dust from the barrier net 20.

[0032] The bottoms of the two bidirectional scrapers 24 are respectively attached to the top of the barrier net 20. By setting the arc-shaped protective ring 21, it can not only provide protection for the transmission structure of the threaded screw 11 and the screw hole block 14 below, but also the two limit slide grooves 22 opened inside can cooperate with the guide slide groove 16 to provide limit guidance for the movement of the screw hole block 14, so that the screw hole block 14 can drive the cooling fan 19 and the bidirectional scraper 24 to move along a precise trajectory, effectively ensuring the heat dissipation and dust cleaning functions of the control cabinet 1.

[0033] Working principle and usage process of this utility model:

[0034] When the elevator door opening and closing precision positioning device is working, the sensing sensor 3 transmits the elevator door status signal to the input interface circuit 5 in the control cabinet 1 through the cable 2. After being processed by the signal processor 7 and the counter 6, the microprocessor 4 analyzes the signal and sends instructions to the relay 8 to control the opening and closing of the elevator door to achieve precise positioning. At the same time, the drive motor 12 drives the threaded screw 11 to rotate, causing the screw hole block 14 to drive the mounting ring 17 and the cooling fan 19 to move left and right along the guide slide 16 through the combination rod 15, so as to dynamically dissipate heat from the heat-generating components in the control cabinet 1. When the screw hole block 14 moves, it drives the limit slide plate 23 to slide in the limit slide 22 of the arc-shaped protective ring 21, so that the bidirectional scraper 24 simultaneously cleans the dust on the barrier net 20, ensuring that the heat dissipation channel is unobstructed. Thus, while precisely controlling the positioning of the control cabinet 1, the movable cooling fan and the automatic dust removal structure ensure the heat dissipation efficiency of the components inside the control cabinet 1.
