Description

Technical Field

[0001] This utility model relates to the field of inclined elevator technology, and in particular to a wireless control device for inclined elevators without a follow cable. Background Technology

[0002] Inclined elevators are mainly used to complete lifting operations along sloping paths. Due to their large load capacity, high rated speed, small operating angle, and long operating distance, inclined elevators require the use of a tank chain as a guide when using traditional traveling cables for signal and data transmission, due to the special nature of their operating structure.

[0003] When the accompanying cable is installed inside the tank chain, the vibration generated during high-speed movement causes the tank chain to shake and produce loud noise. Improper guidance can also lead to the tank chain breaking, creating operational risks. Utility Model Content

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1-4 This utility model provides a technical solution: a wireless control device for inclined stairs without a follow cable, comprising:

[0032] Wireless transmitter 1 is fixedly installed in the computer room;

[0033] Wireless receiver 2, which is fixed on the car of the inclined staircase;

[0034] The wireless transmitter 1 includes a wireless CAN communication module 11, a power adapter 12, a directional antenna 13, and a bracket 14. The wireless CAN communication module 11 is connected to the power adapter 12 via a first network cable 111. The wireless CAN communication module 11 is fixedly mounted on the bracket 14. The first network cable 111 is wound around the take-up reel 141 of the bracket 14. The power adapter 12 is fixedly mounted on the bracket 14. The directional antenna 13 is connected to the power adapter 12 via a second network cable 131. The directional antenna 13 is inserted into the positioning seat 142 on the bracket 14.

[0035] The cableless wireless control device consists of a wireless transmitter 1 on the machine room side and a wireless receiver 2 on the car side. It realizes data interaction between the car side and the machine room side through wireless communication, with an effective communication distance of 3,000 meters, which can completely cover the elevator height / travel length. The running height and running slope angle of the inclined elevator are not limited. It can replace the traditional traveling cable for signal and data transmission, eliminating the safety hazards of inclined elevator operation caused by traveling cable communication.

[0036] The wireless transmitter 1 and the wireless receiver 2 have identical structures. The wireless CAN communication module 11, power adapter 12, and directional antenna 13 required for wireless communication between the wireless transmitter and receiver are integrated on the bracket 14. Excess length of the first network cable 111 is wound up by a cable reel 141, facilitating the installation of wireless control devices in machine rooms and elevator cars. The positioning seat 142 and the bracket 14 form a mounting groove for the directional antenna 13, which positions the directional antenna 13 using a contour-following positioning method. To prevent the directional antenna 13 from detaching from the positioning seat 142, it can be fixed with adhesive.

[0037] The bracket 14 has a triangular structure, with the wireless CAN communication module 11 and the directional antenna 13 symmetrically arranged on both sides of the take-up reel 141. The triangular bracket 14 is not easily deformed or damaged, and the distribution of the wireless CAN communication module 11 and the directional antenna 13 on both sides of the take-up reel 141 avoids accidental operation.

[0038] Working Principle: The wireless CAN communication module 11 can specifically use the LCWLAN-600P wireless module from Leike Electronics to perform bidirectional data transmission between dual-channel CAN and Wi-Fi / Ethernet. The wireless module uses TCPServer as the default communication mode, but TCPClient and other modes can also be selected. When using TCP, a connection must be established before data can be transmitted. TCPServer mode waits for client connections, while TCPClient actively connects to the target IP and target port.

[0039] Therefore, the wireless modules in the wireless transmitter and receiver 2 can be configured as TCPServer and TCPClient, respectively, to connect and send / receive data. Wireless communication does not require additional cabling; the CAN-to-WiFi communication module in the computer room connects wirelessly to the CAN-to-WiFi communication module in the car, providing strong anti-interference capabilities and saving on cabling costs.

[0040] Example 2

[0041] This embodiment further improves upon the above embodiment by providing the following technical solution: The take-up drum 141 is sleeved on the support rod 143 of the bracket 14. A stop block 144 is provided at one end of the support rod 143, and the stop block 144 is detachably mounted on the support rod 143. The inner diameter of the take-up drum 141 is larger than the diameter of the support rod 143, allowing for rotatable installation of the take-up drum 141. The stop block 144 prevents the take-up drum 141 from detaching from the support rod 143.

[0042] One end of the stop block 144 is provided with a conical plug 1441. As the stop block 144 rotates, the plug 1441 can extend into the gap between the inner wall of the take-up drum 141 and the support rod 143, and the stop block 144 presses and positions the take-up drum 141 to prevent the take-up drum 141 from rotating.

[0043] Example 3

[0044] Based on the above embodiments, this embodiment further improves upon the following technical solution: the stop block 144 is provided with a number of circumferentially arranged arc-shaped notches 1442, as shown in the figure, to facilitate the rotation and disassembly of the stop block 144.

[0045] Example 4

[0046] Based on the above embodiments, this embodiment further improves upon the following technical solution: a number of second notches 1411 arranged circumferentially are provided on the end baffle of the take-up drum 141, as shown in the figure. The second notches 1411 facilitate the rotation of the take-up drum 141 and facilitate the observation of the first wire 111 wound on the take-up drum 141.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
