Description

Technical Field

[0001] The present application relates to the technical field of elevators, and in particular to a leveling detection device. Background Art

[0002] When the magnetic scale breaks in an elevator, the elevator needs to stop running to ensure safety. Due to the randomness of the magnetic scale breaking, when this fault occurs, the elevator car may be at any position in the path, causing obstacles for passengers to evacuate the car. At present, the leveling detection switch is often used to determine whether the elevator car has reached the leveling position, but regardless of whether the magnetic scale breaks in the elevator, the leveling detection switch is in the working position. When the magnetic scale works normally, it can detect the position of the elevator car, and there is no need for the leveling detection switch to repeat the detection, resulting in a waste of resources.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

The features defined as "first" and "second" are used to distinguish the feature names, rather than having special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] The embodiment of the present application provides a leveling detection device 100, which includes a leveling detection component, a guide sleeve 201 and a valve core 202. The leveling detection component can move along the guide sleeve 201, thereby switching between a standby position and a working position. When the elevator is working normally, the leveling detection component is in the standby position under the restriction of the valve core 202. At this time, the elevator can use a magnetic scale to detect the position of the car 102. When the magnetic scale of the elevator breaks, the magnetic scale cannot detect the position of the car 102, the limiting effect of the valve core 202 on the leveling detection component is eliminated, and the leveling detection component moves to the working position, thereby detecting and guiding the car 102 to reach the leveling position, so as to facilitate passengers to evacuate the car 102 in time.

[0031] like Figure 1 As shown, in some examples, the leveling detection component is used to detect whether the elevator car 102 has reached the leveling position. When the magnetic scale of the elevator is broken, the elevator car 102 will continue to run a certain distance to make the elevator car 102 reach the leveling position. During the continuous operation of the car 102, if the elevator door head 101 triggers the leveling detection component, it means that the car 102 has reached the leveling position, and the car 102 stops moving.

[0032] like Figure 2 That is, the local enlarged image I and Figure 3 As shown, in some examples, the leveling detection assembly includes a leveling detection switch 301, a trigger rod 302 is provided on the leveling detection switch 301, and the leveling detection switch 301 is horizontally arranged.

[0033] Furthermore, the trigger rod 302 can rotate on the leveling detection switch 301. When the elevator is working normally, the trigger rod 302 always remains horizontal; when the magnetic scale of the elevator is broken and the car 102 has not reached the leveling position, the trigger rod 302 also remains horizontal; when the magnetic scale of the elevator is broken and the car 102 has reached the leveling position, the trigger rod 302 rotates, thereby sending a signal to stop the car 102 from moving.

[0034] In some examples, after the leveling detection assembly reaches the working position, in order to ensure that the leveling detection switch 301 can be triggered at the leveling position, the leveling detection device 100 further includes a trigger structure 103. The trigger structure 103 is generally formed in a rod shape, and the trigger structure 103 is arranged on the elevator's landing door head 101. The position of the trigger structure 103 is fixed, and as the car 102 moves to the leveling position, the leveling detection switch 301 also moves together, so that the trigger structure 103 contacts and toggles the trigger rod 302, and the trigger rod 302 rotates.

[0035] It is worth noting that when the leveling detection assembly is in the working position, the leveling detection switch 301 extends out of the range of the car 102. It can be understood that the leveling detection switch 301 extends toward the door head 101 to facilitate the trigger structure 103 to toggle the trigger rod 302.

[0036] like Figure 4 As shown, the guide sleeve 201 is arranged on the elevator car 102, and the guide sleeve 201 is open on one side, and the guide sleeve 201 includes an open end and a closed end. The leveling detection assembly is inserted into the guide sleeve 201 along the open end of the guide sleeve 201, and the leveling detection assembly inserted into the guide sleeve 201 is slidably connected with the guide sleeve 201, so the leveling detection assembly can slide along the guide sleeve 201.

[0037] It is understandable that when the leveling detection assembly slides, the length of the leveling detection assembly extending out of the guide sleeve 201 also changes. Specifically, when the leveling detection assembly is in the standby position, the length of the leveling detection assembly extending out of the guide sleeve 201 is small, so as to avoid the leveling detection assembly from contacting the trigger structure 103 on the landing door head 101; when the leveling detection assembly is in the working position, the length of the leveling detection assembly extending out of the sleeve is large, so as to facilitate the trigger structure 103 to trigger the leveling detection switch 301 on the leveling detection assembly.

[0038] Furthermore, the valve core 202 is located inside the guide sleeve 201, and the valve core 202 can move inside the guide sleeve 201 to limit the position of the leveling detection assembly. When the leveling detection assembly is in the standby position, the valve core 202 blocks the leveling detection assembly to prevent the leveling detection assembly from moving to the outside of the guide sleeve 201; when the valve core 202 moves away from the leveling detection assembly, the limiting effect of the valve core 202 is eliminated, and the leveling detection assembly can move to the working position.

[0039] In some examples, the valve core 202 moves radially along the guide sleeve 201 in the guide sleeve 201, and a driving structure for driving the valve core 202 to move is arranged on the side wall of the guide sleeve 201. Under the action of the driving structure, the valve core 202 can gradually move from a position blocking the leveling detection component to a position disengaged from the leveling detection component, so as to facilitate the leveling detection component to move to the working position.

[0040] In some examples, the driving structure adopts an electromagnet structure 203, which can absorb the valve core 202, and the electromagnet structure 203 protrudes from the outer wall of the guide sleeve 201. Furthermore, a motion chamber 204 is provided inside the electromagnet structure 203, and the motion chamber 204 is connected to the internal space of the guide sleeve 201, and the position of the valve core 202 corresponds to the position of the motion chamber 204.

[0041] Among them, when the leveling detection component is in the standby position, the electromagnet structure 203 does not work, and the valve core 202 blocks the leveling detection component within the range of the guide sleeve 201; when the leveling detection component needs to move to the working position, the electromagnet structure 203 starts to work and adsorbs the valve core 202 into the moving chamber 204 to separate from the leveling detection component, and the valve core 202 avoids leaving space for the leveling detection component to move.

[0042] In some examples, the leveling detection assembly further includes an epitaxial structure 303, and the epitaxial structure 303 is used to connect the leveling detection switch 301 and the guide sleeve 201. One end of the epitaxial structure 303 is inside the guide sleeve 201, and the other end is outside the guide sleeve 201. It can be understood that the leveling detection assembly is slidably connected to the guide sleeve 201 through the epitaxial structure 303, and the leveling detection switch 301 is connected to the end of the epitaxial structure 303 outside the guide sleeve 201.

[0043] like Figure 5 As shown, in some examples, the epitaxial structure 303 includes a connecting portion 305 and a bending portion 304, wherein the bending portion 304 is located inside the guide sleeve 201, and the connecting portion 305 is at an angle to the bending portion 304. The shape of the bending portion 304 is approximately the same as the shape of the inner space of the guide sleeve 201.

[0044] In some examples, a limit plate 206 is provided at the open end of the guide sleeve 201, and the limit plate 206 can prevent the extension structure 303 from moving out of the guide sleeve 201 beyond the travel. When the extension structure 303 slides to the limit position, the limit plate 206 and the bending portion 304 have structural interference, thereby blocking the extension structure 303 from continuing to slide, and preventing the leveling detection assembly from completely separating from the guide sleeve 201.

[0045] Furthermore, the limiting plate 206 partially covers the opening of the guide sleeve 201 and leaves a gap at the opening of the guide sleeve 201 for arranging the epitaxial structure 303. Therefore, the limiting plate 206 does not affect the sliding of the epitaxial structure 303 while preventing the epitaxial structure 303 from falling off.

[0046] In some examples, an elastic structure 205 is disposed inside the guide sleeve 201, and the elastic structure 205 is located at the closed end of the guide sleeve 201. When the leveling detection assembly is in the standby position, the extension structure 303 extends into the guide sleeve 201 by a large distance, thereby compressing the elastic structure 205. Furthermore, since the valve core 202 maintains the leveling detection assembly in the standby position, the elastic structure 205 can remain in a compressed state.

[0047] Among them, when the valve core 202 eliminates the limiting effect on the leveling detection component through movement, the limiting effect of the epitaxial structure on the elastic structure 205 also disappears, and the elastic structure 205 has a tendency to restore the length in the natural state, thereby pushing the epitaxial structure 303, that is, pushing the leveling detection component to reach the working position.

[0048] It is understandable that the elastic structure 205 acts on the bending portion 304 of the epitaxial structure 303 and has a large contact area with the bending portion 304 , so that the direction of the force transmitted by the elastic structure 205 to the epitaxial structure 303 is consistent with the axial direction of the guide sleeve 201 .

[0049] In some examples, the epitaxial structure 303 is provided with a first mounting hole 306, which is located on the connecting portion 305, and the side wall of the guide sleeve 201 is provided with a second mounting hole 307, the position of which corresponds to the position of the motion chamber 204 of the electromagnet structure 203. During the installation of the valve core 202, the epitaxial structure 303 is pushed to make the first mounting hole 306 dock with the second mounting hole 307, and the valve core 202 successively passes through the second mounting hole 307 and the first mounting hole 306, thereby entering the interior of the guide sleeve 201. Since the width of the valve core 202 is greater than the inner diameter of the guide sleeve 201, the valve core 202 is continuously pushed, and the edge of the valve core 202 can be embedded in the opening of the motion chamber 204, so that the epitaxial structure 303 is clamped at the current position, and the leveling detection assembly is maintained in the standby position.

[0050] During use, when the elevator has a magnetic scale break, the electromagnet structure 203 on the guide sleeve 201 is energized, the valve core 202 retracts, and the extension structure 303 extends, so that the leveling detection component reaches the working position, preparing to trigger the leveling detection switch 301. While controlling the leveling detection switch 301 to be in place, the system obtains the last running position of the elevator through the magnetic scale reading head, and the rotary encoder reads the angular velocity of the elevator. According to the last position of the elevator and the running speed of the elevator, the traction machine is controlled to rotate to a specific angle. After the traction machine rotates to a specific angle, the power is cut off to control the elevator to stop running after running a specific distance, thereby achieving the purpose of controlling the car 102 to move a specific displacement. During the operation of the elevator, if the limit switch of the elevator is triggered, the elevator stops running first, and then broadcasts a voice prompt to the passengers. While the voice broadcast, the system controls the traction machine to reverse a specific angle and stop the traction machine. In the above process, after the magnetic scale breaks, passengers can evacuate the car 102 first, and the elevator can be repaired after the passengers evacuate, thereby improving the passenger experience.

[0052] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
