Description

Technical Field

[0001] This utility model relates to the field of elevator control cabinets, and in particular to an elevator control cabinet with centralized switch arrangement. Background Technology

[0002] Elevator control cabinets typically contain various manual switches. For example, there are inspection buttons and switches. Inspection buttons usually include both up and down buttons, each connected to a corresponding input of the elevator control system. When the inspection up or down button is pressed, the elevator control system receives the corresponding signal and controls the elevator to run at inspection speed. Another example is an emergency brake release button, connected to the brake's electromagnetic coil via the control cabinet. When the button is pressed, the electromagnetic coil is energized, generating magnetic force that attracts the pressure plate on the brake, releasing the brake and allowing the elevator car to move. Yet another example is an emergency stop button, connected to an input of the programmable logic controller (PLC) or directly to the safety... The circuits are connected; for example, a hoistway lighting switch is installed, which is connected to the hoistway lighting fixtures and power supply; for example, a speed governor action reset button is installed, which is connected to the speed governor's electrical reset actuator through a circuit. When the speed governor is activated due to overspeed or other reasons, the reset button needs to be pressed manually, and the electrical reset actuator is triggered through a circuit signal to restore the speed governor to its normal state; for example, an ARD switch is installed, which is connected to the elevator's emergency power supply device through the control cabinet. When the elevator loses power, the ARD switch can automatically switch to emergency power to ensure that the elevator can safely stop and open the car door to allow passengers to leave.

[0003] Currently, the aforementioned manual switches are generally fixedly installed on the inner wall of the control cabinet. In addition, the wiring harnesses connected to each manual switch cause the button layout to be quite messy. When a user needs to operate one of the buttons, not only do they need to turn their head to look inside, but the wiring harnesses also become an obstacle to their view, making it inconvenient to find the button and prone to errors. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an elevator control cabinet with a centralized switch arrangement. The internal manual switches are clearly laid out, making it easy to locate the switches and reducing the likelihood of operational errors.

[0005] An elevator control cabinet includes a cabinet with an entrance, a variety of manual switches connected to their respective electrical components within the cabinet, and a switch central plate disposed within the cabinet and facing the entrance. All of the manual switches are disposed on the switch central plate, and the wiring harnesses connected to their respective manual switches are concealed on the back side of the switch central plate.

[0006] All manual switches are arranged on the same switch panel facing the cabinet entrance, and the wiring harnesses are neatly hidden on the back of the switch panel, no longer exposed. This makes the layout of the manual switches clearer. When users need to find a switch, they only need to look towards the cabinet entrance to immediately focus on the switch panel without having to turn their heads to search. The wiring harnesses no longer become an obstacle to their view, making the search process more convenient, the operation more accurate, and less prone to errors.

[0007] Preferably, the manual switch is a push-button switch with a label.

[0008] Preferably, the switch central plate is also provided with multiple plug-in terminals, and the cables used to connect with the plug-in terminals are hidden on the back side of the switch central plate.

[0009] Preferably, a transformer is installed in the cabinet at the back of the switch central plate, and the switch central plate is also provided with clearance holes for the transformer's fuse to extend into and be removed.

[0010] Preferably, a contactor is also provided in the cabinet at the back of the switch central plate, and the switch central plate separates the contactor from the cabinet entrance.

[0011] Preferably, the control cabinet includes a cabinet door for blocking the cabinet entrance, and the switch central plate extends laterally across the two gaps formed between the cabinet door and the cabinet when the cabinet door is closed.

[0012] Preferably, the switch central plate has connecting flanges on both sides that are connected to the cabinet body, and the connecting flanges are fitted to the inner wall of the cabinet body.

[0013] Preferably, a frequency converter is installed in the cabinet above the switch central plate, and a viewing window corresponding to the frequency converter is provided on the cabinet door.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. In this utility model, all manual switches are arranged on the same switch central panel facing the cabinet entrance, and the wiring harness is neatly hidden on the back side of the switch central panel and is no longer exposed. In this way, the layout of manual switches is clearer. When users need to find a switch, they only need to look towards the cabinet entrance to focus on the switch central panel immediately. There is no need to turn their heads to search, and the wiring harness no longer becomes an obstacle to the view, making the search process more convenient, the operation more accurate, and less prone to errors.

[0016] 2: In this utility model, the plug-in terminals that connect to various cables are also set on the same switch central board, and the cables are hidden on the back side of the switch central board to prevent the cables from becoming an obstruction to the view.

[0017] 3: In this utility model, the contactor is placed on the back side of the switch central plate, that is, the switch central plate separates the contactor from the cabinet entrance. The switch central plate physically shields the contactor to a certain extent, reducing the noise generated by the contactor from being transmitted to the outside of the control cabinet through the cabinet door.

[0018] Figure 1 This is an exploded diagram of the elevator control cabinet.

[0019] Figure 2 This is a cross-sectional view of the elevator control cabinet (only the contactors are shown as electrical components inside the control cabinet). Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example 1:

[0021] like Figure 1 As shown, an elevator control cabinet with centralized switch arrangement includes a cabinet body 1. The cabinet body 1 has a cabinet entrance, and a cabinet door 2 is provided at the cabinet entrance to cover the entrance. The cabinet body 1 is equipped with various manual switches 4, including maintenance buttons and switches, emergency brake release buttons, emergency stop buttons, shaft lighting switches, speed governor action reset buttons, and ARD switches, etc. These manual switches are connected to their corresponding electrical components to achieve comprehensive control of the elevator's operating status.

[0022] It also includes a switch central plate 3 installed in the cabinet 1 and facing the cabinet entrance. All of the above-mentioned manual switches 4 are installed on the switch central plate 3, and the wiring harnesses (not shown in the attached drawings) connected to their respective manual switches 4 are hidden on the back side of the switch central plate 3.

[0023] Since all the manual switches 4 are arranged on the same switch central panel 3 facing the cabinet entrance, and the wiring harness is neatly hidden on the back side of the switch central panel 3 and is no longer exposed, the layout of the manual switches 4 is clearer. When users need to find a switch, they only need to look towards the cabinet entrance to immediately focus on the switch central panel without having to turn their heads to search. The wiring harness no longer becomes an obstacle to their view, making the search process more convenient, the operation more accurate, and less prone to errors.

[0024] In this embodiment, these manual switches 4 are push-button switches with markings. The presence of markings facilitates quick identification of the switches, and the markings can be text labels.

[0025] In this embodiment, the switch central plate 3 is also provided with multiple plug-in terminals 5, and the cables (not shown in the accompanying drawings) used to connect with the plug-in terminals 5 are hidden on the back side of the switch central plate 3 to prevent the cables from becoming an obstruction of sight, making it convenient to locate the switches and reducing the likelihood of operational errors. These cables in elevator systems are typically speed governor cables, main engine cables, brake cables, hoistway signal cables, etc. The signals detected by the sensors at the front end are transmitted to the plug-in terminals 5 through the cables, and then the plug-in terminals 5 transmit the signals to the elevator's PLC (Programmable Logic Controller). The connection of the cables is all existing technology in elevator systems and will not be described in detail here.

[0026] A transformer 6 is typically installed in cabinet 1, serving as overload protection. In this embodiment, the transformer 6 is located on the back side of the switch central plate 3. This is because, considering the overall size of cabinet 1, placing the transformer 6 to the side of the switch central plate 3, or offset from it, would inevitably increase the overall size of cabinet 1. Furthermore, the switch central plate 3 is cleverly designed with clearance holes 31. If the fuse of the transformer 6 burns out due to overload, maintenance personnel can easily remove the damaged fuse and replace it with a new one through these clearance holes 31 without removing the switch central plate 3, thus ensuring the continuous and stable operation of the equipment.

[0027] A contactor 7 is typically installed in cabinet 1. Contactor 7 controls the start, stop, forward and reverse rotation of the traction machine. Contactor 7 generates some noise during operation, such as... Figure 2 As shown, in this embodiment, the contactor 7 is located on the back side of the switch concentration plate 3, that is, the switch concentration plate 3 separates the contactor from the cabinet entrance. The switch concentration plate 3 physically shields the contactor to a certain extent, reducing the noise generated by the contactor from being transmitted to the outside of the control cabinet through the cabinet door 2. Furthermore, in this embodiment, the switch concentration plate 3 horizontally spans the two gaps formed between the cabinet door 2 and the cabinet 1 when the cabinet door 2 is closed. These two gaps are formed on the left and right sides of the cabinet 1, and are two of all the gaps formed between the cabinet door 2 and the cabinet 1 when the cabinet door 2 is closed. Moreover, the two sides of the switch concentration plate 3 are tightly fitted to the inner wall surface of the cabinet 1, thereby effectively shielding these two gaps physically. This design reduces the propagation of noise to the gap between the cabinet 1 and the cabinet door 2 to a certain extent, thereby reducing the transmission of noise from the gap between the cabinet 1 and the cabinet door 2 to the outside of the control cabinet.

[0028] To facilitate the installation or connection of the switch central plate 3, each side of the switch central plate 3 is provided with a connecting flange 32 that connects to the cabinet 1. The connecting flange 32 fits against the inner wall of the cabinet 1. The connecting flange 31 is securely fixed to the cabinet 1 by fastening, welding, or bonding.

[0029] In this embodiment, as Figure 1 As shown, a frequency converter 01 is installed in the cabinet 1 above the switch central plate 3, and a viewing window 20 corresponding to the frequency converter 01 is provided on the cabinet door 2.

[0030] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
