With reference to fig. 1 to 6, an embodiment of the present invention provides a cover plate assembly of a climbing-free device, the cover plate assembly includes a cover plate 1, a motor 2, a rotating assembly and a fixing plate 4, the cover plate 1 is rotatably disposed on a platform 7 of a tower, the motor 2 is disposed on the platform 7, the rotating assembly is connected to the motor 2, the rotating assembly is wound with a traction member 5, a free end of the traction member 5 is connected to the cover plate 1, and the rotating assembly is provided with a trigger plate 3.3.1; the motor 2 is used for driving the rotating assembly to rotate so that the traction piece 5 pulls the cover plate 1 to open or close the lifting vehicle channel 7.1 of the platform 7; fixed plate 4 locates the one side that the rotating assembly dorsad motor 2, and fixed plate 4 is equipped with first limit switch 6.1 and second limit switch 6.2 be connected with motor 2 electricity towards one side of rotating assembly, and first limit switch 6.1 and second limit switch 6.2 are located the rotation stroke that triggers board 3.3.1, and first limit switch 6.1 and second limit switch 6.2's relative position satisfies: when the cover plate 1 opens the lift car channel 7.1 of the platform 7, the trigger plate 3.3.1 triggers the first limit switch 6.1; when the cover plate 1 closes the lift car passage 7.1 of the platform 7, the trigger plate 3.3.1 triggers the second limit switch 6.2.
Therefore, when the motor 2 is started and rotates forwards, the rotating component rotates forwards along with the motor 2. Because the traction piece 5 is wound on the rotating assembly, along with the positive rotation of the rotating assembly, the length of the traction piece 5 between the cover plate 1 and the rotating assembly is gradually reduced, and the cover plate 1 is gradually rotated towards the direction far away from the lift truck channel 7.1 under the pulling of the traction piece 5. When the cover plate 1 opens the lift car channel 7.1 of the platform 7, the trigger plate 3.3.1 of the rotating assembly just rotates to the position of the first limit switch 6.1, and triggers the first limit switch 6.1. When the first limit switch 6.1 is triggered, the motor 2 stops working, namely stops rotating, and the cover plate 1 is not rotated any more, namely is kept in an opening state.
When the motor 2 is started and rotates reversely, the rotating assembly is driven by the motor 2 to rotate reversely. Along with the reverse rotation of the rotating assembly, the length of the traction piece 5 between the cover plate 1 and the rotating assembly is gradually increased, and the cover plate 1 is gradually rotated towards the direction approaching the lift truck channel 7.1 under the driving of the self gravity. When the cover plate 1 closes the lift car passage 7.1 of the platform 7, the trigger plate 3.3.1 of the rotating assembly just rotates to the position of the second limit switch 6.2, and triggers the second limit switch 6.2. When the second limit switch 6.2 is triggered, the motor 2 stops, namely stops rotating, and the cover plate 1 is kept in a closed state without rotating.
It should be noted that the turning direction of the motor 2 and the opening and closing relationship of the lift car passage 7.1 can be set according to actual needs. In addition, the above-mentioned "the cover 1 opens the lift truck passageway 7.1 of the platform 7" means that the orthographic projection of the cover 1 on the platform 7 does not fall into the lift truck passageway 7.1, that is, the included angle between the cover 1 and the platform 7 is not less than 90 °. Similarly, the above-mentioned "the cover plate 1 closes the lift car channel 7.1 of the platform 7" means that the orthographic projection of the cover plate 1 on the platform 7 falls in the lift car channel 7.1, that is, the included angle between the cover plate 1 and the platform 7 is zero.
Therefore, in the embodiment of the present invention, the installation of the cover plate assembly of the climbing-free device is convenient, the applicability is strong, by arranging the trigger plate 3.3.1 on the rotating assembly, and arranging the first limit switch 6.1 and the second limit switch 6.2 on the rotating stroke of the trigger plate 3.3.1, when the rotating assembly indirectly drives the cover plate 1 to open the lift car channel 7.1 of the platform 7, the trigger plate 3.3.1 is used to trigger the first limit switch 6.1 to close the motor 2, so that the cover plate 1 is no longer rotated, i.e. kept in the open state; when the rotating assembly indirectly drives the cover plate 1 to close the lift truck channel 7.1 of the platform 7, the trigger plate 3.3.1 can be used for triggering the second limit switch 6.2 to close the motor 2, so that the cover plate 1 is kept in a closed state without rotating. Because the embodiment of the present invention is that the first limit switch 6.1 and the second limit switch 6.2 are not directly triggered by the cover plate 1, but triggered by the trigger plate 3.3.1 of the rotating assembly, so the installation positions of the first limit switch 6.1 and the second limit switch 6.2 are independent of the size of the cover plate 1, that is, to the cover plates 1 with different specifications and sizes, the installation positions of the first limit switch 6.1 and the second limit switch 6.2 on the fixing plate 4 can be completely the same, and the installation on site does not need to adjust the installation positions of the first limit switch 6.1 and the second limit switch 6.2 on the fixing plate 4.
As shown in fig. 3 to 6, the rotating assembly includes a rotating member 3.1, a driving gear 3.2 and a driven gear 3.3, the rotating shaft of the rotating member 3.1 is connected to the motor 2, the driving gear 3.2 and the rotating member 3.1 are coaxially and relatively fixedly disposed, the driven gear 3.3 is rotatably disposed on the fixing plate 4, the driven gear 3.3 is engaged with the driving gear 3.2, the diameter of the driven gear 3.3 is greater than that of the driving gear 3.2, and the trigger plate 3.3.1 is disposed on the driven gear 3.3. The diameter ratio of the driven gear 3.3 to the driving gear 3.2 is preferably 4: 1-5: 1, the central angle between the first limit switch 6.1 and the second limit switch 6.2 is 90 ° on the rotation stroke of the trigger plate 3.3.1, that is, the rotating shaft of the driven gear 3.3 is used as the center of a circle, and the included angle between the first limit switch 6.1 and the second limit switch 6.2 and the connecting line of the center of a circle is 90 °.
The advantage of this arrangement is that since the rotating shaft of the rotating member 3.1 is connected to the motor 2, the driving gear 3.2 is coaxial with the rotating member 3.1, and therefore the driving gear 3.2 directly reflects the rotation speed of the motor 2, that is, the driving gear 3.2 has the same rotation speed as the motor 2. And because driven gear 3.3 and driving gear 3.2 mesh, and driven gear 3.3's diameter is greater than the diameter of driving gear 3.2, consequently, just can reduce the rotational speed of trigger plate 3.3.1 through driving gear 3.2 and driven gear 3.3 transmission, that is to say, when motor 2 indirectly drives apron 1 and opens or close lift truck passageway 7.1 of platform 7, motor 2 need drive and rotate 3.1 and rotate several circles, and driven gear 3.3's turned angle is less than 360, thereby not only improved the speed reduction efficiency of motor 2, but also guaranteed that apron 1 only can trigger first limit switch 6.1 towards keeping away from lift truck passageway 7.1 pivoted in-process, apron 1 only can trigger second limit switch 6.2 towards the orientation pivoted in-process of approaching lift truck passageway 7.1.
It should be noted that, besides the above structural form, the rotating assembly may also be only the rotating member 3.1, and at this time, the diameter of the rotating member 3.1 needs to be set larger, so as to ensure that the rotating angle of the rotating member 3.1 is smaller than 360 ° when the cover plate 1 opens or closes the lift car passage 7.1.
Among them, there are various ways that the rotating member 3.1 pulls the cover plate 1 to open or close the lift car passage 7.1 through the pulling member 5, for example:
in the first mode, as shown in fig. 1 and 2, the rotating member 3.1 is a sprocket, the towing member 5 is a chain, one end of the chain is connected to the cover plate 1, and the other end of the chain is fixed to the platform 7. Wherein, the chain can be directly fixed on the platform 7, and can also be fixed on the platform 7 through the supporting vertical plate 8. Take the chain to fix on platform 7 through supporting riser 8 as an example, supporting riser 8 fixes on platform 7 this moment, and the one end and the apron 1 of chain are connected, and another of chain is fixed on supporting riser 8. Therefore, when the motor 2 is started, the chain wheel rotates along with the motor, and the length of the chain between the cover plate 1 and the chain wheel is reduced or increased along with the continuous meshing of the chain and the chain wheel.
In the second mode, the rotating part 3.1 is a winding drum, the traction part 5 is a cable, one end of the cable is wound on the winding drum, and the other end of the cable is connected with the cover plate 1. When the motor 2 is started, the drum rotates along with the motor, and the cable is gradually wound on the drum or the cable wound on the drum is gradually loosened.
Further, the first limit switch 6.1 and the second limit switch 6.2 are photosensors. The photo sensor may be, but is not limited to, a slot type photo sensor or a correlation type photo sensor. Taking a groove-type photoelectric sensor as an example, the groove-type photoelectric sensor comprises a base, an emitter and a receiver, wherein the base is provided with a groove, and the emitter and the receiver are respectively arranged on two sides of the groove. Therefore, as shown in fig. 4, when the cover plate 1 opens the lift car channel 7.1 of the platform 7, the trigger plate 3.3.1 of the rotating assembly just rotates into the groove of the first limit switch 6.1, at this time, the light beam emitted by the emitter of the first limit switch 6.1 is shielded by the trigger plate 3.3.1, the corresponding receiver cannot receive the light beam emitted by the emitter, the receiver outputs a closing signal, and the motor 2 stops rotating according to the closing signal. Similarly, when apron 1 closed platform 7's lift truck passageway 7.1, rotating assembly's trigger plate 3.3.1 rotates just to second limit switch 6.2's recess in, the light beam that the transmitter of second limit switch 6.2 sent then is sheltered from by trigger plate 3.3.1 this moment, and the light beam that the transmitter sent can not be received to the receiver that corresponds, and this receiver just outputs a shut-off signal, and motor 2 then stops rotating according to this shut-off signal. Of course, the first limit switch 6.1 and the second limit switch 6.2 may be micro switches in addition to photo sensors.
As shown in fig. 2, in order to facilitate installation, the cover plate assembly further includes a supporting vertical plate 8 detachably connected to the platform 7, the fixing plate 4 is disposed opposite to the supporting vertical plate 8, the motor 2 is fixed on one side of the supporting vertical plate 8 opposite to the fixing plate 4, and the rotating assembly is disposed between the supporting vertical plate 8 and the fixing plate 4. Wherein, the fixed plate 4 can be fixed with the supporting vertical plate 8 through bolts. Before leaving the factory, the staff can fix motor 2 on supporting riser 8 earlier, then install rotating assembly on motor 2, will draw 5 to wind and establish on rotating assembly after that, install fixed plate 4 on supporting riser 8 through the bolt at last can. From this, during on-the-spot installation, installer only need earlier with support riser 8 through the bolt fastening on platform 7, then will draw the free end of 5 fix on apron 1 can, whole installation very convenient, greatly reduced on-the-spot installer's working strength, improved the installation effectiveness.
As shown in fig. 1 and 2, a flange 8.1 facing the cover plate 1 is formed on one side of the supporting vertical plate 8 adjacent to the cover plate 1, the flange 8.1 is provided with a return spring 9, and the return spring 9 is located on the rotation stroke of the cover plate 1. Of course, the supporting vertical plate 8 can be made of U-shaped channel steel directly.
In the process that the motor 2 drives the rotating assembly to rotate positively, the cover plate 1 is pulled by the traction piece 5 to gradually rotate towards the direction far away from the lift car channel 7.1. After the top surface of apron 1 touched reset spring 9, along with the continuation rotation of apron 1, reset spring 9 is constantly compressed until apron 1 opens lift truck passageway 7.1. Thus, when the motor 2 drives the rotating assembly to rotate reversely, the cover plate 1 starts to rotate towards the direction approaching the lift truck passage 7.1 under the driving of the elastic force of the return spring 9 and the self gravity thereof. Along with the rotation of the cover plate 1, when the cover plate 1 is separated from the contact with the return spring 9, the cover plate 1 continues to rotate towards the direction approaching the lift truck channel 7.1 under the driving of the self gravity until the cover plate 1 closes the lift truck channel 7.1. It can be seen that the return spring 9 is able to provide initial power to the cover 1 to rotate towards the lift car channel 7.1.
For the convenience of control, the cover plate assembly further comprises a controller 10, and the first limit switch 6.1 and the second limit switch 6.2 are electrically connected with the motor 2 through the controller 10. Specifically, the controller 10 is configured to control the motor to be turned off according to the feedback signal of the first limit switch 6.1 or the second limit switch 6.2 within a set time period, and to control the motor to be turned off in a case where the feedback signals of the first limit switch 6.1 and the second limit switch 6.2 are not received within the set time period. Wherein the set time is preferably 4-7 seconds.
Therefore, when the motor 2 is started and rotates forwards, the rotating assembly is driven by the motor 2 to rotate forwards along with the motor, and the cover plate 1 is pulled by the traction piece 5 to gradually rotate towards the direction away from the lift truck channel 7.1. When the cover plate 1 opens the lift car channel 7.1 of the platform 7, the trigger plate 3.3.1 of the rotating assembly triggers the first limit switch 6.1, the controller 10 controls the motor 2 to be closed according to the received feedback signal sent by the first limit switch 6.1, and at the moment, the cover plate 1 does not rotate any more, namely, the cover plate is kept in an open state. When the motor 2 is started and rotates reversely, the rotating assembly rotates reversely under the driving of the motor 2, and the cover plate 1 rotates gradually towards the direction approaching to the lift truck channel 7.1 under the driving of the self gravity. When the cover 1 closes the lift car passage 7.1 of the platform 7, the trigger plate 3.3.1 of the rotating assembly triggers the second limit switch 6.2. The controller 10 controls the motor 2 to be turned off according to the received feedback signal sent by the second limit switch 6.2, and at the moment, the cover plate 1 does not rotate any more, namely, the cover plate is kept in a closed state.
If the controller 10 does not receive the feedback signals of the first limit switch 6.1 and the second limit switch 6.2 within the set time length, it indicates that the first limit switch 6.1 or the second limit switch 6.2 has failed, and at this time, the controller 10 directly controls the motor 2 to be turned off, so as to prevent the cover plate 1 from being excessively opened or closed, and further damage the motor 2 and the cover plate 1.
Of course, in addition to determining whether the first limit switch 6.1 or the second limit switch 6.2 is faulty in a manner of setting the duration, the following manner may be used:
the cover plate assembly further comprises an alarm electrically connected with the controller 10, the first limit switch 6.1 and the second limit switch 6.2 are normally closed switches, and the controller 10 is used for controlling the motor to be closed and controlling the alarm to be started under the condition that feedback signals of the first limit switch 6.1 and the second limit switch 6.2 are not received. Because the first limit switch 6.1 and the second limit switch 6.2 are normally closed switches, the first limit switch 6.1 and the second limit switch 6.2 are both kept connected under the condition that the first limit switch is not triggered, and when the trigger plate 3.3.1 of the rotating assembly triggers the first limit switch 6.1 or the second limit switch 6.2, the first limit switch and the second limit switch are disconnected and send feedback signals to the controller 10, namely, at least one of the first limit switch 6.1 and the second limit switch 6.2 is connected under a normal state, the controller 10 can only receive one feedback signal at most, so that when the controller 10 receives the feedback signals of the first limit switch 6.1 and the second limit switch 6.2 at the same time, the first limit switch 6.1 and the second limit switch 6.2 are both disconnected, at least one of the first limit switch and the second limit switch has a fault, and then the controller 10 directly controls the motor 2 to be turned off and starts an alarm.

Since the lift car 11 is provided with magnetic members, when the lift car 11 moves downward and passes through the magnetic induction sensor group located above the lift car passage 7.1 under the condition that the lift car 11 is located above the platform 7, the lift car 11 first triggers the first magnetic induction sensor 14.1 of the magnetic induction sensor group and then triggers the second magnetic induction sensor 14.2. At this time, the control board receives the feedback signal of the first magnetic induction sensor 14.1 earlier than the feedback signal of the second magnetic induction sensor 14.2, and the control board can determine that the lift car 11 moves downwards at this time, that is, moves towards the cover plate 1, according to the sequence of receiving the feedback signals of the first magnetic induction sensor 14.1 and the second magnetic induction sensor 14.2. From this, the control panel passes through the corotation of relay control motor 2, and along with the continuous corotation of runner assembly, apron 1 rotates towards the direction of keeping away from lift truck passageway 7.1 gradually under the pulling of traction member 5. When the cover plate 1 opens the lift car channel 7.1 of the platform 7, the trigger plate 3.3.1 of the rotating assembly just rotates to the position of the first limit switch 6.1, and triggers the first limit switch 6.1. At the moment, the control board controls the relay to be switched off according to the received feedback signal of the first limit switch 6.1, so that the motor 2 is stopped, and the cover plate 1 is not rotated any more, namely, is kept in an open state.
The lift car 11 continues to move downward after passing through the lift car passage 7.1 of the platform 7. When the lift car 11 passes through the set of magnetic induction sensors located below the lift car passageway 7.1, the lift car 11 triggers the first magnetic induction sensor 14.1 of the set of magnetic induction sensors before triggering the second magnetic induction sensor 14.2. At this moment, the control panel receives the feedback signal of first magnetic induction sensor 14.1 earlier than the feedback signal of receiving second magnetic induction sensor 14.2, and the control panel according to the precedence of receiving first magnetic induction sensor 14.1 and second magnetic induction sensor 14.2 feedback signal, alright confirm that lift truck 11 moves downwards this moment and keeps away from apron 1 removal promptly. From this, the control panel passes through the reversal of relay control motor 2, and apron 1 rotates towards the direction of approaching lift truck passageway 7.1 gradually under self gravity drive. When the cover plate 1 closes the lift car passage 7.1 of the platform 7, the trigger plate 3.3.1 of the rotating assembly just rotates to the position of the second limit switch 6.2, and triggers the second limit switch 6.2. At the moment, the control board controls the relay to be switched off according to the received feedback signal of the second limit switch 6.2, so that the motor 2 is stopped, and the cover plate 1 is not rotated any more, namely, is kept in a closed state.
Similarly, in the situation where the lift car 11 is located below the platform 7, when the lift car 11 moves upward and passes through the set of magnetic induction sensors located below the lift car channel 7.1, the lift car 11 first triggers the second magnetic induction sensor 14.2 of the set of magnetic induction sensors, and then triggers the first magnetic induction sensor 14.1. At this time, the control board receives the feedback signal of the second magnetic induction sensor 14.2 earlier than the feedback signal of the first magnetic induction sensor 14.1, and the control board can determine that the lift car 11 moves upward, that is, moves toward the cover plate 1, according to the sequence of receiving the feedback signals of the first magnetic induction sensor 14.1 and the second magnetic induction sensor 14.2. Therefore, the control panel controls the motor 2 to rotate positively through the relay, and the cover plate 1 gradually rotates in the direction away from the lift truck channel 7.1 under the pulling of the traction piece 5. When the cover plate 1 opens the lift car passage 7.1 of the platform 7, the trigger plate 3.3.1 of the rotating assembly triggers the first limit switch 6.1. The control panel is according to the disconnection of the feedback signal control relay of the first limit switch 6.1 that receives, and then makes motor 2 shut down, and apron 1 no longer rotates and keeps opening promptly.
The lift car 11 continues to move upward after passing through the lift car passage 7.1 of the platform 7. When passing through the magnetic induction sensor group located above the lift car channel 7.1, the lift car 11 triggers the second magnetic induction sensor 14.2 in the magnetic induction sensor group first, and then triggers the first magnetic induction sensor 14.1. The control panel can confirm that the lift truck 11 moves upwards at this moment, namely moves towards the direction far away from the cover plate 1 according to the sequence of receiving the feedback signals of the first magnetic induction sensor 14.1 and the second magnetic induction sensor 14.2. From this, the control panel passes through the reversal of relay control motor 2, and apron 1 rotates towards the direction of approaching lift truck passageway 7.1 gradually under self gravity drive. When the cover 1 closes the lift car passage 7.1 of the platform 7, the trigger plate 3.3.1 of the rotating assembly triggers the second limit switch 6.2. At the moment, the control board controls the relay to be switched off according to the received feedback signal of the second limit switch 6.2, so that the motor 2 is stopped, and the cover plate 1 is not rotated any more, namely, is kept in a closed state.
