[0041] See Figure 1 and Figure 2The diagram shows a schematic of the structure of a landing door guide rail mechanism in one embodiment of this application. The landing door guide rail mechanism includes a back plate 100, a guide rail frame 200, a pulley assembly 300, a left door hanging plate 400, a right door hanging plate 500, a door lock assembly 600, and a switch assembly 700. The back plate 100 is used to be connected to the elevator shaft at the top of the landing door by fasteners, so that the entire landing door track mechanism is fixed. The back plate 100 is provided with the guide rail frame 200.

[0042] The pulley assembly 300 is mounted on the back plate 100. The pulley assembly 300 includes a first pulley 310, a second pulley 320 and a linkage rope 330. The first pulley 310 is rotatably disposed at one end of the guide rail frame 200, the second pulley 320 is rotatably disposed at the other end of the guide rail frame 200, and the linkage rope 330 is wound around the first pulley 310 and the second pulley 320.

[0043] The left door mounting plate 400 is movably mounted on the guide rail frame 200. The left door mounting plate 400 is used to connect the left landing door and is connected to the linkage rope 330. The right door mounting plate 500 is movably mounted on the guide rail frame 200. The right door mounting plate 500 is used to connect the right landing door and is connected to the linkage rope 330. The left door mounting plate 400, the right door mounting plate 500, and the linkage rope 330 form a linkage structure to drive the pulley assembly 300 to drive the left door mounting plate. The left door plate 400 and the right door plate 500 move towards each other to the closed position or away from each other to the open position. When the elevator car needs to run, the left door plate 400 and the right door plate 500 respectively drive the left landing door and the right landing door to move towards each other to the closed position. At this time, the left landing door and the right landing door are closed. When the elevator car door opens, the left door plate 400 and the right door plate 500 drive the left landing door and the right landing door to move away from each other to the open position. At this time, the left landing door and the right landing door are open.

[0044] The door lock assembly 600 includes a lock base 610 and a lock hook 620. The lock base 610 is connected to the back panel 100, and the lock hook 620 is movably disposed on the right door hanging plate 500 or the left door hanging plate 400. In a preferred embodiment of this application, the lock hook 620 is movably disposed on the right door hanging plate 500. When the left door hanging plate 400 and the right door hanging plate 500 are in the closed position, the lock hook 620 is connected to the lock base 610. That is, when the left and right doors are closed, the left and right doors are locked by connecting the lock hook 620 to the lock base 610. The left and right doors will only open when the lock hook 620 is disconnected from the lock base 610.

[0045] The switch assembly 700 includes a door lock switch 710 and a contact 720. The door lock switch 710 is mounted on the back plate 100, and the contact 720 is connected to the lock hook 620. The contact 711 of the door lock switch 710 is arranged facing the side. When the lock hook 620 is connected to the lock seat 610, the contact 720 is connected to the contact 711 of the door lock switch 710, so that the door lock switch 710 receives the landing door closed signal.

[0046] The landing door guide rail mechanism described in this application embodiment has a back plate 100 for fixing the landing door track mechanism to the elevator shaft at the top of the landing door. The track frame 200 is installed on the back plate 100, so that the left door hanging plate 400 and the right door hanging plate 500 are movably mounted on the track frame 200. The two ends of the track frame 200 are provided with a first pulley 310 and a second pulley 320. A linkage rope 330 is sleeved on the first pulley 310 and the second pulley 320. The linkage rope 330 connects the left door hanging plate 400 and the right door hanging plate 500, so that the left door hanging plate 400 and the right door hanging plate 500 move in opposite directions or move away from each other. To lock the left door panel 400 and right door panel 500 when closed, a locking hook 620 is provided on either the left door panel 400 or the right door panel 500, and a locking seat 610 is provided on the back plate 100. When the left door panel 400 and right door panel 500 are in the closed position, the locking hook 620 engages with the locking seat 610, thereby locking the left door panel 400 and right door panel 500 and preventing the elevator doors from being opened in the closed state, ensuring the stability of elevator operation. Furthermore, a switch assembly 700 is needed to verify the connection between the locking hook 620 and the locking seat 610. A door lock switch 710 is provided on the back plate 100, and a contact 720 is provided on the locking hook 620. When the locking hook 620 engages with the locking seat 610, it drives the contact 720 to connect to the contact 711 of the door lock switch 710, thereby giving the door lock switch 710 a closed signal.

[0047] The landing door guide rail mechanism described in this application reduces the accumulation of dust in the shaft at the door lock switch 710 contacts 711 by oriented the contacts 711 of the door lock switch 710 towards the side, thus preventing dust from affecting the electrical conduction between the contacts 720 and the door lock switch 710 and ensuring the safety and stability of elevator operation.

[0048] In some embodiments, such as Figure 2As shown, the lock hook 620 has a rotating hole 620A, and the right door hanging plate 500 or the left door hanging plate 400 has a rotating shaft 510. The lock hook 620 is rotatably connected to the rotating shaft 510 through the rotating hole 620A. The extended surface formed by the contacts 711 of the door lock switch 710 passes through the center of the rotating hole 620A. Specifically, the door lock switch 710 includes multiple contacts 711, which are distributed on the same plane, and this plane passes through the center of the rotating hole 620A. The lock hook 620 is rotatably connected to the left door hanging plate 400 or the right door hanging plate 500. When the lock hook 620 needs to lock the lock seat 610, the lock hook 620 is driven to rotate and engage with the lock seat 610, thereby locking the left door hanging plate 400 and the right door hanging plate 500.

[0049] Furthermore, such as Figure 2 As shown, in this embodiment, the extended plane formed by connecting the contacts 711 of the door lock switch 710 passes through the rotation center of the lock hook 620, thereby causing the lock hook 620 to drive the contact 720 to rotate. The movement trajectory of the contact 720 is an arc. When the contact 720 contacts the contact 711, the contact 720 can enter the contact 711 of the door lock switch 710 along the tangent direction of the arc trajectory. When the door is closed by a large self-closing force on the landing door side, the risk of the switch being damaged is reduced, and the reliability of the switch assembly 700 is improved.

[0050] In an exemplary embodiment, a bearing is provided between the locking hook 620 and the rotating shaft 510. By providing the rotating shaft, the rotational friction of the locking hook 620 can be reduced, and the rotational accuracy of the locking hook 620 can be improved, so that the locking hook 620 can rotate more smoothly around the rotating shaft 510, ensuring the normal opening and closing of the elevator landing door and improving the operational stability of the door lock assembly 600.

[0051] Combination Figure 3This diagram illustrates the structure of the first limiting wheel of the landing door guide rail mechanism in one embodiment of this application. In an optional embodiment, the left door hanging plate 400 includes a first limiting wheel 410, which is mounted on the left door hanging plate 400. A first flange 420 is provided on the side of the first limiting wheel 410 away from the left door hanging plate 400. The left door hanging plate 400 is movably mounted on the guide rail frame 200 via the first limiting wheel 410, and the first flange 420 is engaged between the guide rail frame 200 and the back plate 100. The left door hanging plate 400 slides on the guide rail frame 200 via the first limiting wheel 410. To prevent the first limiting wheel 410 from derailing from the guide rail frame 200, the prior art typically requires the guide rail frame 200 to enclose the limiting wheel for anti-derailment purposes, making it difficult to simplify the structure of the guide rail frame 2000. The first limiting wheel 410 of this application is provided with a first flange 420, which is locked between the guide rail frame 200 and the back plate 100 to prevent the first limiting wheel 410 from detaching from the guide rail frame 200, so that the left door hanging plate 400 is always kept on the guide rail frame 200, thereby improving the reliability of the floor door guide rail mechanism.

[0052] Similarly, the right door hanging plate 500 includes a second limiting wheel 520, which is installed on the right door hanging plate 500. A second flange is provided on the side of the second limiting wheel 520 away from the right door hanging plate 500. The right door hanging plate 500 is movably mounted on the guide rail frame 200 via the second limiting wheel 520, and the second flange is engaged between the guide rail frame 200 and the back plate 100. The right door hanging plate 500 slides on the guide rail frame 200 via the second limiting wheel 520. To prevent the second limiting wheel 520 from derailing from the guide rail frame 200, the second limiting wheel 520 is equipped with a second flange, which is engaged between the guide rail frame 200 and the back plate 100. This prevents the second limiting wheel 520 from detaching from the guide rail frame 200, ensuring that the right door hanging plate 500 remains on the guide rail frame 200, thus improving the reliability of the landing door guide rail mechanism.

[0053] In an optional embodiment, such as Figure 1 As shown, the linkage rope 330 is configured as an upper linkage rope 331 and a lower linkage rope 332 spaced apart between the first pulley 310 and the second pulley 320, and the locking hook 620 is disposed between the upper linkage rope 331 and the lower linkage rope 332. Since the linkage rope 330 is wound between the first pulley 310 and the second pulley 320, the linkage rope 330 is spaced apart as an upper linkage rope 331 and a lower linkage rope 332. By placing the locking hook 620 between the upper linkage rope 331 and the lower linkage rope 332, the height dimension of the landing door guide rail mechanism is saved, making the landing door guide rail mechanism smaller and saving the space occupied by the landing door guide rail mechanism.

[0054] Furthermore, such as Figure 1As shown, the left door hanging plate 400 is connected to the upper linkage rope 331, and the right door hanging plate 500 is connected to the lower linkage rope 332. In other embodiments, the left door hanging plate 400 is connected to the lower linkage rope 332, and the right door hanging plate 500 is connected to the upper linkage rope 331. To enable the left door hanging plate 400 and the right door hanging plate 500 to move in opposite directions, the left door hanging plate 400 is connected to the upper linkage rope 331, and the right door hanging plate 500 is connected to the lower linkage rope 332, or the left door hanging plate 400 is connected to the lower linkage rope 332, and the right door hanging plate 500 is connected to the upper linkage rope 331. When the left door hanging plate 400 is driven, the right door hanging plate 500 is driven to move in opposite directions via the linkage rope 330, thereby achieving the effect of linkage between the left door hanging plate 400 and the right door hanging plate 500.

[0055] In an optional embodiment, such as Figure 1 As shown, the left door hanging plate 400 is provided with a first limiting member 430, and the lower linkage rope 332 abuts against the first limiting member 430 during movement. The right door hanging plate 500 is provided with a second limiting member 540, and the lower linkage rope 332 abuts against the second limiting member 540 during movement. By setting the first limiting member 430 and the second limiting member 540, the left door hanging plate 400 and the right door hanging plate 500 abut against the lower linkage rope 332, providing support for the left door hanging plate 400 and the right door hanging plate 500, preventing the left door hanging plate 400 and the right door hanging plate 500 from deviating downward from the track, and improving the operational stability of the landing door guide rail mechanism.

[0056] For example, the first limiting member 430 and the second limiting member 540 are limiting bolts. By adjusting the extension length of the limiting bolts, the vibration of the left door hanging plate 400 and the right door hanging plate 500 during elevator operation or excessive vertical movement in case of accidents can be prevented, thus avoiding the left door hanging plate 400 and the right door hanging plate 500 from detaching from the guide rail frame 200, thereby ensuring the stability of the landing door guide rail mechanism.

[0057] In an optional embodiment, such as Figure 2 As shown, the locking hook 620 includes a connecting part 621, which is disposed on one side of the locking hook 620. The connecting part 621 has a locking hook groove 621A for accommodating the lock seat 610. By providing the locking hook groove 621A, when the left door hanging plate 400 and the right door hanging plate 500 are closed to the closed position, the locking hook 620 is driven to rotate, which allows the lock seat 610 to engage with the locking hook groove 621A, thereby locking the left door hanging plate 400 and the right door hanging plate 500, thus locking the landing door and preventing the landing door from being opened during elevator car operation, ensuring safety during use.

[0058] In an optional embodiment, such as Figure 2As shown, the lock hook 620 also includes an adjusting part 622, which is disposed on the top of the lock hook 620. The door lock assembly 600 also includes a first adjusting pulley 630 and a second adjusting pulley 640. The first adjusting pulley 630 is rotatably disposed on the adjusting part 622, and the second adjusting pulley 640 is rotatably disposed on the right door hanging plate 500 or the left door hanging plate 400. The second adjusting pulley 640 is disposed on one side of the first adjusting pulley 630. In order to drive the lock hook 620 to lock or unlock the lock seat 610, the first adjusting pulley 630 is rotatably disposed on the lock hook 620, and the second adjusting pulley 640 is disposed on the right door hanging plate 500 or the left door hanging plate 400 on one side of the first adjusting pulley 630. The first adjusting pulley 630 rotates around the second adjusting pulley 640 under the drive of the door knife of the elevator car, thereby driving the lock hook 620 to rotate and locking or unlocking the door lock assembly 600.

[0059] In an optional embodiment, such as Figure 1 As shown, the landing door guide rail mechanism also includes a self-closing spring 800. One end of the self-closing spring 800 is connected to the left door mounting plate 400 or the right door mounting plate 500, and the other end is connected to the back plate 100. By setting the self-closing spring 800, the left door mounting plate 400 and the right door mounting plate 500 can drive the landing door to achieve the function of automatic closing. When the landing door closes under the action of the self-closing spring 800, it will push the locking hook 620 to accurately enter the locking position, improving the stability of elevator operation.

[0060] Secondly, an elevator is provided, including the landing door guide rail mechanism described in any of the above embodiments. The landing door guide rail mechanism is disposed in the elevator shaft above the landing door. The left door mounting plate 400 of the landing door guide rail mechanism is connected to the left landing door, and the right door mounting plate 500 of the landing door guide rail mechanism is connected to the right landing door. When the door knife of the car acts on the first adjusting pulley 630 of the landing door guide rail mechanism, it can drive the locking hook 620 to rotate, thereby driving the locking hook 620 to connect or separate from the lock seat 610.

[0061] In the elevator described in this application embodiment, the contact 711 of the door lock switch 710 of the landing door guide rail mechanism is arranged to the side, thereby reducing the accumulation of dust in the shaft at the contact 711 of the door lock switch 710, preventing dust from affecting the communication between the contact 720 and the door lock switch 710, and ensuring the safety and stability of elevator operation.

[0062] The landing door guide rail mechanism and elevator described in this application have the following beneficial effects:

[0063] 1. By setting the contacts 711 of the door lock switch 710 to face the side, the accumulation of dust in the shaft is reduced, thus preventing dust from affecting the connection between the contacts 720 and the door lock switch 710, and ensuring the safety and stability of elevator operation.

[0064] 2. By connecting the contacts 711 of the door lock switch 710 to form an extended plane that passes through the rotation center of the lock hook 620, the lock hook 620 drives the contact 720 to rotate. When the contact 720 contacts the contact 711, the contact 720 enters the contact 711 of the door lock switch 710 from the tangential direction of the motion circle. When the door is closed by a large self-closing force on the landing door side, the risk of the switch being damaged is reduced, and the reliability of the switch assembly 700 is improved.
