Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of elevator maintenance, and specifically, to a bypass device, a maintenance system, and a maintenance method for elevator landing doors and car doors. Background Art
[0002] When maintaining an elevator, bypass operations need to be performed on the landing door and the car door. Currently, the commonly used bypass devices for elevator landing doors and car doors include integrated circuit wiring boards, landing door / car door bypass adapters, and plug-in landing door / car door bypass devices.
[0003] Among them, the integrated circuit wiring board realizes bypassing the landing door or the car door by changing the position of the plug-in connector on the circuit wiring board. However, the integrated circuit manufacturing technology is relatively complex, and the manufacturing cost is relatively high. Coupled with the investment and labor costs in the production process, the total cost of the integrated circuit is relatively high. During the manufacturing process of the integrated circuit wiring board, strict production and testing processes can reduce the occurrence of faults, but there are still phenomena of defective products during the manufacturing process. It is relatively difficult to repair, and a large number of defects will directly lead to the scrapping of the product. In addition, during use, frequent plugging and unplugging operations on the circuit board are likely to damage the circuit board, resulting in the failure of the bypass function.
[0004] The landing door / car door bypass adapter is a rotary bypass device. Taking the center line of the cylinder as the axis, by rotating the inner cylinder or the outer cylinder, the change of the rotation position is realized, so as to realize bypassing the landing door and the car door. However, the production and processing technology of the landing door / car door bypass adapter is relatively complex, with many processes, cumbersome assembly, and the electrical components used have low versatility. They are basically customized products of ABS or acrylic, and the on-site operation is not convenient enough. The stability of the rotating part is relatively poor, and the failure rate is relatively high.
[0005] The plug-in landing door / car door bypass device currently has a relatively complex product structure, all of which have structural settings such as rotating baffles or moving baffles. The structural size is relatively large, which occupies a relatively large space in the elevator cabinet, so the cabinet size has to be changed to adapt to the application of this bypass device. Summary of the Invention
[0006] The present invention is made to solve the above technical problems. One of its purposes is to provide a bypass device for elevator landing doors and car doors, which has the advantages of low manufacturing cost, low failure rate, and small volume.
[0007] Another purpose of the present invention is to provide an elevator maintenance system and a maintenance method, which facilitate maintenance personnel to perform bypass operations and maintenance operations safely, quickly, and accurately.

[0010] As an embodiment, the normal state plug is internally provided with two sets of two normal plug pins shorted together; wherein, when the normal state plug is plugged into the bypass socket, the first set of normal plug pins shorted together shorts the two socket pins connected in the bypass detection safety circuit connection, and the second set of normal plug pins shorted together shorts the two socket pins connected in the bypass detection signal connection.
[0011] As an embodiment, the landing door bypass plug, the car door bypass plug and the normal state plug have the same appearance and the same number of internal pins, and the surfaces of the three plugs are respectively provided with their own name marks.
[0012] As an embodiment, one ends of the normal state plug, the landing door bypass plug and the car door bypass plug are connected together.
[0013] According to an embodiment of the present invention, an elevator maintenance system is provided, including: a mounting plate, which is provided with mounting holes on it and bypass signs on its surface; a bypass socket, which is arranged in the mounting holes and is internally provided with a plurality of socket pins connected to a bypass circuit; a landing door bypass plug, which is internally provided with at least one set of two landing door plug pins shorted together; a car door bypass plug, which is internally provided with at least one set of two car door plug pins shorted together; a normal state plug, which is internally provided with two sets of two normal plug pins shorted together; a main control circuit board, which is connected with a bypass detection safety circuit connection wire, a bypass detection signal connection wire, a landing door circuit and a car door circuit; a maintenance switch, the two ends of which are respectively connected to both sides of the bypass detection safety circuit connection wire, and when closed, short-circuits the bypass detection safety circuit connection wire; an audible and visual alarm device, which is connected to the main control circuit board and emits audible and visual alarm information when the elevator is in a bypass operation state; wherein, when the landing door bypass plug is inserted into the bypass socket, the two socket pins connected to both sides of the landing door are shorted; when the car door bypass plug is inserted into the bypass socket, the two socket pins respectively connected to both sides of the car door are shorted; when the normal state plug is inserted into the bypass socket, the first set of normal plug pins shorted together short-circuits the two socket pins in the bypass detection safety circuit connection wire, and the second set of normal plug pins shorted together short-circuits the two socket pins in the bypass detection signal connection wire.
[0014] As an embodiment, when the elevator is running normally, the normal state plug is inserted into the bypass socket; after the normal state plug leaves the bypass socket, the bypass detection safety circuit connection wire and the bypass detection signal connection wire are disconnected, and the main control circuit board controls the elevator to stop running.
[0015] According to an embodiment of the present invention, an elevator maintenance method is provided, which is applied to the elevator maintenance system as described above, including: removing the normal state plug on the bypass socket to make the elevator enter the bypass state and stop running; inserting the landing door bypass plug into the bypass socket to bypass the landing door of the elevator, or inserting the car door bypass plug into the bypass socket to bypass the car door of the elevator; closing the maintenance switch to short-circuit the bypass detection safety circuit connection wire, reset the safety circuit signal of the main control circuit board, and make the elevator run slowly up or down for maintenance operations.

The cost of the installation plate itself is relatively low. The bypass socket, landing door bypass plug, and car door bypass plug can use standard components in the market. It only needs to short-circuit the corresponding pins inside the plug and connect the pins of the socket to the bypass circuit of the elevator to form the bypass device for the elevator landing door and car door. Compared with independently customizing the bypass device, the manufacturing cost can be significantly reduced, and the failure rate is also lower. In addition, the installation plate of the bypass device for the elevator landing door and car door can be fixed on any panel of the elevator machine room, and the overall structure of the exposed plugs is relatively small. The small volume facilitates the installation of the bypass device in a narrow machine room. Description of the Drawings

[0032] Unless otherwise clearly defined and limited, the terms "installed", "connected", and "coupled" shall be construed broadly. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] According to an embodiment of the present invention, a bypass device for an elevator landing door and a car door is provided. Please refer to Figures 1 to 3 The bypass device for the elevator landing door and the car door includes a mounting plate 1, a bypass socket 2, a landing door bypass plug 4, and a car door bypass plug 5.
[0034] The mounting plate 1 is a plate body, provided with mounting holes thereon, and provided with a bypass mark 15 on the surface. During use, the mounting plate 1 can be fixedly installed on any panel in the elevator machine room. The mounting holes thereon are used to mount and fix the bypass socket 2. The bypass mark 15 is a pattern specified by the elevator design specification. For example, the bypass mark 15 that meets the requirements of the landing door and car door bypass can be laser marked on the surface of the mounting plate 1 by laser etching.
[0035] The bypass socket 2 is fixedly arranged in the mounting hole, and is internally provided with a plurality of socket pins connected to the bypass circuit. Two of the socket pins are respectively connected to both sides of the landing door in the circuit, and when the two socket pins are short-circuited, the landing door can be short-circuited; at least two of the socket pins are respectively connected to both sides of the car door in the circuit, and when the two socket pins are short-circuited, the car door can be short-circuited.
[0036] The landing door bypass plug 4 is internally provided with at least one set of two landing door plug pins short-circuited together. When the landing door bypass plug 4 is plugged into the bypass socket 2, the two landing door plug pins short-circuited together are respectively connected to the above two socket pins connected to both sides of the landing door, and then the two socket pins are short-circuited, and finally the landing door is short-circuited.
[0037] The car door bypass plug 5 is internally provided with at least one set of two car door plug pins short-circuited together. When the car door bypass plug 5 is plugged into the bypass socket 2, the two car door plug pins short-circuited together are respectively connected to the above two socket pins connected to both sides of the car door, and then the two socket pins are short-circuited, and finally the car door is short-circuited.
[0038] The landing door bypass plug 4 and the car door bypass plug 5 in the bypass device of the elevator landing door and car door are similar to two keys and can be hung at any position in the elevator machine room without occupying much space. When it is necessary to bypass the landing door or the car door, only need to insert the landing door bypass plug 4 or the car door bypass plug 5 into the above bypass socket 2, and the landing door or the car door can be bypassed, which is convenient for subsequent elevator maintenance operations.
[0039] The bypass device of the elevator landing door and car door only additionally adds a mounting plate 1 and socket plugs on the existing elevator. The cost of the mounting plate 1 itself is relatively low. The bypass socket 2, the landing door bypass plug 4 and the car door bypass plug 5 can use standard parts in the market. Only need to short-circuit the corresponding pins inside the plug and connect the pins of the socket to the bypass circuit of the elevator to form the bypass device of the elevator landing door and car door. Compared with independently customizing the bypass device, the manufacturing cost can be significantly reduced, and the failure rate is also lower. In addition, the mounting plate 1 of the bypass device of the elevator landing door and car door can be fixed on any panel of the elevator machine room, and the overall structure of the exposed plugs is relatively small, and the small volume is convenient for setting the bypass device in a narrow machine room.
[0040] As an implementation, in this embodiment, the bypass device for the elevator landing door and car door further includes a normal state plug 3, and at least one set of two normal plug pins shorted together are provided inside the normal state plug 3. Correspondingly, two socket pins respectively connected to the bypass detection safety loop connection line 7 are further provided in the bypass socket 2. Only when these two socket pins are shorted can the bypass detection safety loop connection line 7 conduct and work. Therefore, when the normal state plug 3 is plugged into the bypass socket 2, the two normal plug pins therein are respectively connected to the two socket pins, and then the two socket pins are shorted, finally realizing the conduction of the bypass detection safety loop connection line 7. By plugging and unplugging the normal state plug 3 on the bypass socket 2, the elevator can identify whether it is in the bypass state or the normal state currently.
[0041] Further, in this embodiment, two sets of normal plug pins shorted together are provided inside the normal state plug 3, with two pins in each set. The first set of normal plug pins is used to conduct the above-mentioned bypass detection safety loop connection line 7, and the second set of normal plug pins is used to conduct the above-mentioned bypass detection signal connection line 6. Specifically, two socket pins respectively connected to the bypass detection signal connection line 6 are further provided in the bypass socket 2. Only when these two socket pins are shorted can the bypass detection signal connection line 6 conduct and work. Therefore, when the normal state plug 3 is plugged into the bypass socket 2, the second set of normal plug pins are respectively connected to the two socket pins, and then the two socket pins are shorted, finally realizing the conduction of the bypass detection signal connection line 6. By plugging and unplugging the normal state plug 3 on the bypass socket 2, the elevator can identify whether it is in the bypass state or the normal state currently, and whether bypass detection is performed.
[0042] As an implementation, the shapes and the numbers of internal pins of the landing door bypass plug 4, the car door bypass plug 5 and the normal state plug 3 are the same, and respective name identifiers are provided on the surfaces of the three plugs. In other words, these three plugs can adopt the same standard parts products. Only by shorting the pins at the required positions and in the required quantities inside them can the three plugs have different functions when in use, which can further reduce the manufacturing cost of the bypass device for the elevator landing door and car door. Setting name identifiers on their surfaces facilitates workers to accurately identify the functions of each plug during maintenance operations.
[0043] As an implementation, one end of the normal state plug 3, the landing door bypass plug 4 and the car door bypass plug 5 is connected together. For example, round holes are provided at one end of the three, and then the three can be connected together through a cable tie. In practical applications, only one of the three is plugged into the bypass socket 2, and the other two are hung on the bypass socket 2. Connecting the three together is not easy to lose, and there is no need to additionally set up a structure for placing idle plugs in the elevator machine room.
[0044] Such as Figures 1 to 3As shown, in a specific embodiment, the bypass device for the elevator landing door and car door simultaneously includes the above-mentioned mounting plate 1, bypass socket 2, landing door bypass plug 4, car door bypass plug 5, and normal state plug 3.
[0045] There are 9 socket pins provided in the bypass socket 2, which are respectively Figure 3 pin 1, pin 2, pin 3, pin 4, pin 5, pin 6, pin 7, pin 8, and pin 9 of Figure 3 . Pin 1 is connected to point A in the figure, pin 2 is connected to point B in the figure, pin 3 is connected to point C in the figure, pin 4 is connected to point D in the figure, pin 6 is connected to point E in the figure, pin 7 is connected to point F in the figure, pin 8 is connected to point G in the figure, and pin 9 is connected to the 24V external DC regulated power supply in the figure.
[0046] Specifically, when pin 1 and pin 2 are short-circuited, the 1# car door 11 can be short-circuited; when pin 2 and pin 3 are short-circuited, two landing doors can be short-circuited; when pin 3 and pin 4 are short-circuited, the 2# car door 14 can be short-circuited; when pin 6 and pin 7 are short-circuited, the bypass detection signal connection line 6 can be conducted; when pin 8 and pin 9 are short-circuited, the bypass detection safety loop connection line 7 can be conducted.
[0047] There are also 9 pins corresponding to the above socket pins in the landing door bypass plug 4, car door bypass plug 5, and normal state plug 3. Among them, pin 6 and pin 7 of the normal state plug 3 are short-circuited together, and pin 8 and pin 9 of the normal state plug 3 are short-circuited together. After the normal state plug 3 is inserted into the bypass socket 2, pin 6 of the normal plug is connected to pin 6 of the socket, pin 7 of the normal plug is connected to pin 7 of the socket, pin 8 of the normal plug is connected to pin 8 of the socket, and pin 9 of the normal plug is connected to pin 9 of the socket, which can conduct the bypass detection signal connection line 6 and conduct the bypass detection safety loop connection line 7.
[0048] Pin 2 and pin 3 of the landing door bypass plug 4 are short-circuited together. After the landing door bypass plug 4 is inserted into the bypass socket 2, pin 2 of the landing door plug is connected to pin 2 of the socket, and pin 3 of the landing door bypass plug is connected to pin 3 of the socket, which can short-circuit two landing doors.
[0049] The pin of the No. 1 car door plug in the car door bypass plug 5 is shorted to the No. 2 car door bypass plug 5, and the pin of the No. 3 car door plug is shorted to the pin of the No. 4 car door bypass plug 5. After the car door bypass plug 5 is inserted into the bypass socket 2, the pin of the No. 1 car door plug is connected to the pin of the No. 1 socket, the pin of the No. 2 car door plug is connected to the pin of the No. 2 socket, the pin of the No. 3 car door plug is connected to the pin of the No. 3 socket, and the pin of the No. 4 car door plug is connected to the pin of the No. 4 socket, which can short-circuit the two car doors.
[0050] Further, in this embodiment, an elevator maintenance system is also disclosed. Please refer to Figure 3 , this elevator maintenance system includes the above bypass device, the main control circuit board 9, the maintenance switch 16 and the sound and light alarm device 8. The main control circuit board 9 is connected to the landing door circuit and the car door circuit of the elevator, and is also connected to the bypass detection safety circuit connection line 7 and the bypass detection signal connection line 6, and is used to control the operation of the elevator according to a preset program. The structure of the main control circuit board 9 and the method of controlling the operation of the elevator are determined by the elevator itself and are not the innovative points of this application, so details will not be described here.
[0051] Both ends of the maintenance switch 16 are respectively connected to both sides of the bypass detection safety circuit connection line 7. When the maintenance switch 16 is closed, the bypass detection safety circuit connection line 7 is short-circuited. The sound and light alarm device 8 is connected to the main control circuit board 9 and emits sound and light alarm information when the elevator is in the bypass state.
[0052] In this elevator maintenance system, when the elevator is running normally, the normal state plug 3 is inserted into the bypass socket 2; after the normal state plug 3 leaves the bypass socket 2, the bypass detection safety circuit connection line 7 and the bypass detection signal connection line 6 are disconnected, and the main control circuit board 9 controls the elevator to stop running, which can prevent people other than maintenance workers from taking the elevator and avoid safety accidents.
[0053] Based on this elevator maintenance system, in this embodiment, an elevator maintenance method is also disclosed, which mainly includes the following steps:
[0054] Remove the normal state plug 3 on the bypass socket 2 to make the elevator enter the bypass state and stop running;
[0055] Insert the landing door bypass plug 4 into the bypass socket 2 to bypass the landing door of the elevator, or insert the car door bypass plug 5 into the bypass socket 2 to bypass the car door of the elevator;
[0056] Close the maintenance switch 16 to short-circuit the bypass detection safety circuit connection line 7, reset the safety circuit signal of the main control circuit board 9, and make the elevator run slowly up or down for maintenance work.
[0057] The following will further illustrate this elevator maintenance system and maintenance method in conjunction with Figure 3 this.
[0058] When the elevator is in the normal state (normal operation or normal standby), the normal state plug 3 is inserted into the bypass socket 2. At this time, the bypass detection signal connection wire 6 conducts the 24V external DC regulated power supply to the X6 point of the main control circuit board 9; at the same time, the bypass detection safety circuit connection wire 7 conducts the X25 safety circuit of the main control circuit board 9; at this time, the main control board detects that the elevator is in the normal state.
[0059] When in the landing door bypass operation, pull out the normal state plug 3 from the bypass socket 2. At this time, the bypass detection signal connection wire 6 disconnects the 24V external DC regulated power supply from the X6 point of the main control circuit board 9, and the main control circuit board 9 detects that it enters the landing door or car door bypass operation state; at the same time, the bypass detection safety circuit connection wire 7 disconnects the X25 safety circuit signal of the main control circuit board 9. Due to the disconnection of the safety circuit, the elevator stops at this time. Insert the landing door bypass plug 4 into the bypass socket 2. At this time, the landing door bypass plug 4 shorts the 1# landing door 12 and the 2# landing door 13, shorting all the landing doors. At this time, the 1# car door 11 and the 2# car door 14 are in the normal state and are not shorted. Manually rotate the maintenance switch 16. At this time, the bypass detection safety circuit connection wire 7 is bypassed and shorted, and the X25 safety circuit signal of the main control circuit board 9 is reset and connected. Manually perform slow upward or slow downward operation, and the elevator performs landing door bypass operation. During the bypass operation, the C2 point of the car top control board 10 outputs. At this time, the sound and light alarm device 8 gives a beeping and sound and light prompt. During this process, maintenance operations can be carried out layer by layer.
[0060] When in the car door bypass operation, pull out the normal state plug 3 from the bypass socket 2. At this time, the bypass detection signal connection wire 6 disconnects the 24V external DC regulated power supply from the X6 point of the main control circuit board 9, and the main control circuit board 9 detects that it enters the landing door or car door bypass operation state; at the same time, the bypass detection safety circuit connection wire 7 disconnects the X25 safety circuit signal of the main control circuit board 9. Due to the disconnection of the safety circuit, the elevator stops at this time. Insert the car door bypass plug 5 into the bypass socket 2. At this time, the car door bypass plug 5 shorts the 1# car door 11 and the 2# car door 14, shorting all the car doors. At this time, the 1# landing door 12 and the 2# landing door 13 are in the normal state and are not shorted. Manually rotate the maintenance switch 16. At this time, the bypass detection safety circuit connection wire 7 is bypassed and shorted, and the X25 safety circuit signal of the main control board is reset and connected. Manually perform slow upward or slow downward operation, and the elevator performs car door bypass operation. During the bypass operation, the C2 point of the car top control board 10 outputs. At this time, the sound and light alarm device 8 gives a beeping and sound and light prompt. During this process, maintenance operations can be carried out layer by layer.
[0061] As described above, when switching the operating state of the elevator to the normal mode, the bypass landing door mode, or the bypass car door mode by inserting different function plugs into the same bypass socket 2, only one function plug can be inserted each time, and the contacts of the landing door and the car door cannot be bypassed simultaneously. Therefore, the relevant regulations for bypassing the landing door and the car door can be satisfied with the optimal structure and the hardware with the best cost performance.
[0062] The bypass socket 2 and the function plugs with 9 pins each are set above according to the circuit connection sequence of two specific landing doors, two car doors and their characteristics. In other embodiments, the number of pins in the socket and the plug can also be adjusted accordingly according to the number of landing doors and car doors in the actual elevator and their circuit connection sequence, as long as it is ensured that all the landing doors or all the car doors or some of the landing doors or some of the car doors can be bypassed.
[0063] For example, in Figure 3 , place the 2# car door 14 between point A and point B. At this time, only by short-circuiting the pin of socket No. 1 and the pin of socket No. 2 can the short-circuiting of all the car doors be achieved. In this case, the number of pins in the bypass socket 2 and each function plug can be appropriately reduced.
[0064] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
