Detailed Description

To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

A door interlock mechanism and an elevator of the present application will be described below with reference to fig. 1 to 7.

As shown in fig. 1 to 5, the present embodiment provides a gantry crane interlocking mechanism, and the gantry crane interlocking mechanism 1 includes: the installation seat 11, the linkage assembly 12, the locking piece 13 and the clamping piece 14.

The mount 11 is mounted to the car 2 of the elevator by a fastener such as a bolt; one end of the linkage component 12 is connected with a switch door 21 of the cage 2, and the other end is movably arranged on the mounting seat 11; the locking piece 13 is connected with the linkage assembly 12, and the locking piece 13 is provided with a clamping part 131 and a contact part 132; the clamping piece 14 is arranged on the mounting seat 11 and is positioned on one side of the locking piece 13.

Under the condition that the abutting portion 132 is not in contact with the touch piece 3, the clamping portion 131 on the locking piece 13 is clamped with the clamping piece 14, and the locking piece 13 controls the switch door 21 to be in a closed state through the linkage assembly 12.

In the case where the interference portion 132 interferes with the touching member 3, the lock member 13 may be separated from the catching member 14 by the driving of the touching member 3, so that the opening and closing door 21 can be opened.

Specifically, the linkage assembly 12 of the present embodiment may include at least one link, and one end of the linkage assembly 12 may be connected to the opening/closing door 21 of the car 2 in a direct contact or non-contact manner.

Meanwhile, in order to ensure that the opening and closing state of the opening and closing door 21 can be controlled based on the position change of the locking member 13 relative to the mounting seat 11, the other end of the linkage assembly 12 may be movably connected to the mounting seat 11 in a hinged manner or a rope connection manner.

In practical application, the elevator is usually arranged in a high-altitude building or a tower drum, the high-altitude building or the tower drum is usually provided with a plurality of levels along the height direction, and the touch piece 3 can be arranged at each level of the elevator, so that the switch door 21 of the elevator car 2 can be opened when the elevator car 2 moves to each level.

When the lift car 2 of the elevator is in lifting operation, the lift car 2 drives the door interlocking mechanism 1 to move up and down relative to each touch piece 3. When the abutting portion 132 of the door interlocking mechanism 1 does not touch the touching member 3, the locking member 13 is at the first position relative to the mounting seat 11, and the clamping portion 131 on the locking member 13 is clamped with the clamping member 14.

Because the linkage assembly 12 is arranged between the switch door 21 and the mounting seat 11 of the car 2, and the locking piece 13 is connected with the linkage assembly 12, when the clamping part 131 on the locking piece 13 is clamped with the clamping piece 14, the locking piece 13 limits the transmission of the linkage assembly 12, and the switch door 21 of the car 2 cannot be opened.

Correspondingly, when conflict portion 132 contradicts to touching piece 3, owing to under the drive of touching piece 3, joint portion 131 and joint 14 separation on the locking piece 13, and locking piece 13 can move to the second position, and locking piece 13 no longer restricts the transmission of interlock subassembly 12 this moment, can make switch door 21 open under the effect of external force.

As can be seen from the above, in the embodiment of the present application, in the process that the door interlocking mechanism 1 moves up and down along with the car 2 of the elevator, the opening and closing state of the switch door 21 on the car 2 can be controlled according to the contact state of the abutting portion 132 on the locking member 13 and the touching member 3, so as to ensure that the switch door 21 cannot be opened during the operation of the elevator, and only when the abutting portion 132 on the locking member 13 touches the touching member 3, the switch door 21 can be opened, which is beneficial to ensuring the operation safety of the operator.

In some embodiments, as shown in fig. 1, the linkage assembly 12 of the present embodiment includes a weight member 121 and a link assembly 122.

The top end of the counterweight 121 is rotatably arranged on the car 2, and the counterweight 121 is arranged on one side of the switch door 21; latch member 13 is connected to linkage assembly 122; one end of the connecting rod assembly 122 is fixedly connected with the top end of the counterweight member 121, and the other end is movably connected with the mounting seat 11.

As shown in fig. 4 and 5, in the case that the opening and closing door 21 of the car 2 is configured as an inward opening door, the present embodiment may be configured such that the weight member 121 is disposed in the car 2, a top end of the weight member 121 is rotatably connected to a door frame of the opening and closing door 21, and the weight member 121 is disposed inside the opening and closing door 21 and near a top end of the opening and closing door 21.

Alternatively, the top end of the weight member 121 is higher than the top end of the opening and closing door 21, and the bottom end of the weight member 121 is lower than the top end of the opening and closing door 21. The counterweight 121 is strip-shaped, one side of the top end of the counterweight 121 is rotatably connected with one side of the switch door 21 through a bearing, the other side of the top end of the counterweight 121 is rotatably connected with the other side of the switch door 21 through a transfer shaft, and the transfer shaft is fixedly connected with one end of the connecting rod assembly 122.

So, when the conflict portion 132 of lock piece 13 does not contact with touching piece 3, not only joint portion 131 and the joint 14 joint on the lock piece 13, the weight member 121 keeps the hang down state naturally under the effect of dead weight moreover, is difficult to open the switch door 21 of car 2 through external force this moment.

When the abutting portion 132 of the lock member 13 contacts the touch member 3, the engaging portion 131 of the lock member 13 and the engaging member 14 are separated from each other by the driving of the touch member 3, and the opening/closing door 21 of the car 2 can be opened by an external force. In a state where the opening and closing door 21 is in the opened state, the weight member 121 may be deflected by a preset angle with respect to the vertical plane by the driving of the opening and closing door 21 to reach the deflected state. Wherein the preset angle is determined by the opening degree of the opening and closing door 21.

Along with the operation of lift of elevator, when conflict portion 132 of locking piece 13 and touching 3 switch over to the separation state from the contact state, counterweight 121 can be by the effect of dead weight automatically switch over to the natural state of droing from the state of deflecting to under counterweight 121's drive, realize joint portion 131 and the joint 14 on the locking piece 13 and resume the joint.

Accordingly, when the contact portion 132 of the locking member 13 contacts the touch member 3 again with the elevator being lifted, the interlocking mechanism 1 of the door motor can perform the interlocking action again, which is not described in detail herein.

In some embodiments, as shown in fig. 1, the linkage assembly 122 of embodiments of the present application includes a first linkage 1221, a second linkage 1222, and a third linkage 1223.

A first end of the first link 1221 is fixedly connected to the top end of the weight member 121, and a second end of the first link 1221 is rotatably connected to a first end of the second link 1222; the second end of the second link 1222, the first end of the third link 1223, and one end of the locking member 13 are coaxially and rotatably connected, and the second end of the third link 1223 is rotatably connected to the mounting seat 11.

Specifically, the weight member 121 of this embodiment is fixedly connected to the first end of the first link 1221 through a coupling shaft, the second end of the first link 1221 is hinged to the first end of the second link 1222 through a first pin, the second end of the second link 1222, the first end of the third link 1223 and one end of the locking member 13 are hinged together through a second pin, and the second end of the third link 1223 is rotatably mounted on a fixed shaft on the mounting seat 11.

The central axes of the transfer shaft, the first pin shaft, the second pin shaft and the fixed shaft are parallel to each other, and the transfer shaft, the first pin shaft, the second pin shaft and the fixed shaft are parallel to the surface of the mounting base 11.

Thus, when the weight member 121 rotates relative to the vertical surface, the weight member 121 may drive the first link 1221 to rotate synchronously therewith, and the portion where the second end of the second link 1222 is hinged to the first end of the third link 1223 is driven by the first link 1221 to translate relative to the mounting seat 11.

Therefore, in the present embodiment, the locking member 13 is rotatably disposed at the hinged portion of the second link 1222 and the third link 1223, so that the counterweight 121 and the locking member 13 can be better linked, and the clamping state of the locking member 13 and the clamping member 14 matches with the deflection state of the counterweight 121.

In some embodiments, as shown in fig. 2, in order to achieve better clamping between the locking member 13 and the clamping member 14, the clamping portion 131 of the embodiment of the present application includes a clamping groove, and the clamping groove is disposed on one side of the locking member 13 facing the clamping member 14; at least part of the clip members 14 can be clipped into the card slots.

Specifically, the slot of this embodiment has a first slot wall and a second slot wall, and the first slot wall and the second slot wall are disposed opposite to each other. Wherein the first and second slot walls are not specifically illustrated in fig. 2.

Meanwhile, the clamping member 14 includes a first side plate 141 and a second side plate 142, a side of the first side plate 141 is connected to a side of the second side plate 142, and the first side plate 141 and the second side plate 142 are disposed at an included angle.

For example, the first side plate 141 and the second side plate 142 are disposed in a "V" shape, and the included angle between the first side plate 141 and the second side plate 142 is an acute angle.

The included angle between the first side plate 141 and the second side plate 142 may be determined according to the inclination angles of the first groove wall and the second groove wall of the card slot.

Based on the above arrangement, under the condition that the abutting portion 132 is separated from the touching member 3, the first side plate 141 and the first groove wall abut against each other, so that the clamping member 14 is clamped in the clamping groove; in the case where the interference portion 132 interferes with the touching member 3, the second side plate 142 and the second groove wall are in sliding contact to guide the engaging member 14 to be disengaged from the engaging groove.

As shown in fig. 1, 2 and 4, the switching door 21 is initially in a closed state when the elevator starts a lifting operation. Because the contact portion 132 of the locking member 13 does not contact the touch member 3, the engaging member 14 is engaged with the engaging slot, at this time, if the switch door 21 is acted by an external force and tends to open, the weight member 121 will rotate counterclockwise, the weight member 121 will drive the second connecting rod 1222 to move upward through the first connecting rod 1221, and the second connecting rod 1222 will drive the locking member 13 to move upward relative to the mounting seat 11. At this time, the first side plate 141 of the engaging member 14 and the first groove wall of the engaging groove abut against each other, so that the engaging member 14 is prevented from being disengaged from the engaging groove.

Accordingly, when the abutting portion 132 of the lock member 13 contacts the touching member 3, the touching member 3 drives the lock member 13 away from the engaging member 14 as the elevator ascends or descends. In this process, it is ensured that the card member 14 is smoothly separated from the card slot based on the sliding contact between the second side plate 142 of the card member 14 and the second slot wall of the card slot.

In some embodiments, as shown in fig. 1, in order to reduce the contact friction between the interference portion 132 of the locking member 13 and the touching member 3, the interference portion 132 of the present embodiment includes a roller, which may be a steel-cored polyurethane rubber-coated roller, and the roller is rotatably disposed on the locking member 13, and the roller is configured to be in rolling contact with the touching member 3.

As shown in fig. 3, the touching member 3 of the present embodiment includes a first guide plate 31, a connecting plate 32, and a second guide plate 33.

One end of the connecting plate 32 is connected to the first end of the first guide plate 31, and the other end is connected to the first end of the second guide plate 33; the first guide plate 31 and the second guide plate 33 are respectively provided obliquely toward the same side of the connecting plate 32; the distance between the second end of the first guide plate 31 and the second end of the second guide plate 33 is greater than the length of the connecting plate 32.

In practical applications, the touch piece 3 further includes an adapter plate 34, the adapter plate 34 is connected to the connection plate 32, and the connection plate 32 is suitable for being connected to the fixed structure of each corresponding layer of the elevator.

Wherein the connecting plate 32 is arranged vertically, and the first guide plate 31 and the second guide plate 33 are respectively disposed obliquely with respect to the vertical plane.

In the process that the car 2 of elevator ascends from the next floor level to the next floor level, because the position that touching piece 3 set up is fixed, conflict portion 132 of locking piece 13 conflicts the surface of second guide board 33 earlier, because the horizontal distance of the first end of second guide board 33 for conflict portion 132 is less than the horizontal distance of the second end of second guide board 33 for conflict portion 132, then under the drive of second guide board 33, joint 14 breaks away from the draw-in groove gradually.

As the car 2 ascends, the catching member 14 is completely released from the catching groove when the interference portion 132 interferes with the surface of the connection plate 32. If the car 2 does not need to open the door at the upper floor level, when the car 2 continues to ascend, since the horizontal distance of the first end of the first guide plate 31 relative to the abutting part 132 is smaller than the horizontal distance of the second end of the first guide plate 31 relative to the abutting part 132, the engaging member 14 is engaged with the engaging groove again under the gravity driving action of the counterweight member 121 and the guide of the first guide plate 31.

Accordingly, in the process that the car 2 of the elevator descends from the upper floor level to the lower floor level, since the position where the touching member 3 is disposed is fixed, the interference part 132 of the locking member 13 first interferes with the surface of the first guide plate 31, and since the horizontal distance of the first end of the first guide plate 31 relative to the interference part 132 is smaller than the horizontal distance of the second end of the first guide plate 31 relative to the interference part 132, the engaging member 14 gradually disengages from the engaging groove under the driving of the first guide plate 31.

When the abutting portion 132 abuts on the surface of the connecting plate 32 as the car 2 descends, the engaging member 14 is completely disengaged from the engaging groove. If the car 2 does not need to open the door at the next floor level, in the process of the car 2 continuing to descend, because the horizontal distance between the first end of the second guide plate 33 and the abutting part 132 is smaller than the horizontal distance between the second end of the second guide plate 33 and the abutting part 132, the clamping member 14 is clamped in the clamping groove again under the guide of the gravity of the counterweight member 121 and the second guide plate 33.

In some embodiments, to achieve the opening and closing state of the switching door 21 and the interlock control of the driving mechanism of the elevator, the door interlocking mechanism 1 of the present embodiment is further provided with a trigger switch 15.

In a case where the abutting portion 132 of the lock member 13 is separated from the touch member 3, the lock member 13 is away from the trigger switch 15, so that the trigger switch 15 is in the first switching state, so that the drive mechanism of the elevator is in the operating state.

In a case where the abutting portion 132 of the lock member 13 abuts against the touch member 3, the lock member 13 approaches the trigger switch 15, so that the trigger switch 15 is in the second switch state, so that the driving mechanism stops operating.

So, when conflict portion 132 of locking piece 13 does not touch touching 3, joint portion 131 and the joint 14 joint on the locking piece 13 not only to make switch door 21 be in the closure state, trigger switch 15 does not receive the trigger signal of locking piece 13 in addition, makes trigger switch 15 control the actuating mechanism's of elevator circular telegram operation under first on-off state, thereby realizes that the elevator opens door 21 in the lift operation and can not open, in order to avoid the elevator operation to open the incident because of switch door 21 accident appears.

Correspondingly, when conflict portion 132 of locking piece 13 touched touching piece 3, not only joint portion 131 and joint 14 on the locking piece 13 broke away from, and trigger switch 15 received the trigger signal of locking piece 13 moreover for trigger switch 15 controls the actuating mechanism stop operation of elevator under the second on-off state, thereby realizes when switch door 21 was opened, and the elevator can not go up and down to move, with guarantee operation personnel's safety, reduces the potential safety hazard.

In practical application, the trigger switch 15 is electrically connected with a control module of the electric cabinet, and the control module is electrically connected with a driving mechanism of the elevator. Thus, the trigger switch 15 can feed back a switching value signal to the control module, and the control module controls the start-stop state of the driving mechanism.

The trigger switch 15 may adopt a proximity switch, a travel switch, an infrared correlation switch and other switch devices known in the art, and as long as the switch devices capable of switching the switch state under the trigger of the locking piece 13 meet the design requirements; the control module includes but is not limited to a microprocessor, a PLC controller and a single chip microcomputer.

In some embodiments, as shown in fig. 1 and 2, the trigger switch 15 of the embodiments of the present application comprises a travel switch.

The travel switch and the clamping piece 14 are respectively arranged on the opposite sides of the locking piece 13; the lock member 13 is further provided with a trigger portion 133, and a contact of the stroke switch is used to contact with or separate from the trigger portion 133.

As shown in fig. 6 and 7, an embodiment of the present application also provides an elevator, including: car 2, actuating mechanism, touching piece 3 and door machine interlocking device 1 as any one above.

The door machine interlocking mechanism 1 is arranged on the car 2, and the driving mechanism is connected with the car 2 to drive the car 2 to lift and move; the touching member 3 is fixedly arranged on one side of the car 2 along the moving path of the car 2.
