- when located at the unlock position, locking mechanism releases the holding or driving to the position of brake component frizzen 32.
Trigger electromagnet 300 it is electric after by release conditions be converted to adsorbed state, brake component frizzen 32 is fastenedly connected In the trigger electromagnet iron core 301 of trigger electromagnet 300, so that trigger electromagnet 300 adsorbs brake component frizzen 32, when When brake component frizzen 32 is adsorbed, it is believed that brake component frizzen 32 is in non-trigger position.The dead electricity of trigger electromagnet 300 Release conditions are converted to by adsorbed state afterwards, so as to no longer adsorb brake component frizzen 32, so as to brake component frizzen 32 are moved to trigger position in the presence of spring 34 is triggered, when brake component frizzen 32 is located at trigger position, braking parts Part frizzen 32 and is pushed into on-position tight against the brake component of firmly falling proof device.
The falling proof device and its brake component, specifically can with as shown in fig. 7, falling proof device safety tongs component In 20, one group of disc spring 25 5 reversely stacks, and has a disc spring pad 29 in outermost, disc spring 25 is together with disc spring pad 29 String is on disc spring axle 24.There is screw thread at the both ends of disc spring axle 24, and one end is arranged on wedge guide pad 28, every piece of wedge guide pad 28 install two disc spring axles 24 altogether.The other end of two disc spring axles 24 both passes through safety tongs housing 21, then passes through nut check. Every piece of bearing slide plate 26 is respectively embedded into each self-corresponding wedge guide plate 23, then by bolt by bearing slide plate 26 and wedge Guide plate 23 is fixed on wedge guide pad 28 together.The lower end of wedge guide plate 23 is provided with caging bolt 30, can prevent wedge 16 skid off from wedge guide plate 23.There is screwed hole the upper end of wedge 16 as the brake component of falling proof device, is provided with 27 Bolt, by nut check, bolt 27 it is Height Adjustable.
When wedge 16 is triggered, wedge 16 will be jacked up, and pass through leading for wedge guide plate 23 and wedge guide pad 28 To effect, two pieces of wedges 16 clamp upward sliding to centre simultaneously.Wedge braking operation face 22 contacts friction with braking surface (such as Guide rail both sides), braking is realized by frictional force between the two.In the action of the clamping guide-rail of wedge 16, wedge 16, wedge are led Reaction force to plate 23 and the meeting of wedge guide pad 28 by from guide rail to both sides, by the guiding of disc spring axle 24, disc spring 25 is pressed Tight deformation so that safety tongs component 20 (except wedge 16) relative to oriented two Slideslip of equipment action, due to compressing disc spring 25 this process are progressive process, and when completing, the decrement of disc spring 25 is preset value, therefore thrust is constant and controllable, It is also constant and controllable that this allows for frictional force caused by wedge braking operation face 22 in wedge 16.It can so prevent from touching Excessive acceleration be present so that personnel come to harm when sending out safety tongs.
Further, when trigger electromagnet 300 electric must be in adsorbed state, 32 toggled electricity of brake component frizzen The absorption of magnet 300 and be maintained at non-trigger position;When the dead electricity of trigger electromagnet 300 is in release conditions, trigger electromagnet The brake component frizzen 32 of 300 release absorption.Wedge 16 is controlled by trigger electromagnet 300.Trigger electromagnet 300 is installed On electromagnet stent 35, it is then fitted into safety tongs fixed plate 19.Trigger electromagnet 300 includes trigger electromagnet iron core 301, screwed hole is arranged at the top of trigger electromagnet iron core 301.Triggering spring 34 passes through trigger electromagnet iron core 301, triggers spring 34 One end is against in trigger electromagnet 300, and the other end is against on triggering end plate 33.Triggering bolt as brake component frizzen 32 A nut is first penetrated, triggering end plate 33 is then passed through, is locked in the screwed hole at the top of trigger electromagnet iron core 301.
In the situation of carrying platform system normal operation, brake component frizzen 32 passes through trigger electromagnet iron core 301 The electromagnet 300 that is triggered adsorbs;When receiving triggering command in emergency (such as carrying platform rapidly drops), triggering electricity Magnet 300 will discharge trigger electromagnet iron core 301 to discharge brake component frizzen 32, will now be triggered by triggering spring 34 End plate 33, trigger electromagnet iron core 301 and brake component frizzen 32 are upspring together.As shown in Figure 8, two brake components Frizzen 32 is commonly mounted on triggering end plate 33, so when no matter brake component frizzen 32 is adsorbed or discharged, can Keep synchronization action.
Further, the locking mechanism includes keeping electromagnet 310, retaining hook 36;Brake component frizzen 32 fastens It is installed on triggering end plate 33;Electromagnet 310 is kept to pass through the switching between adsorbed state and release conditions so that retaining hook 36 Moved between holding position and non-retaining position position:
- when positioned at holding position, the position of the locking triggering end plate 33 of retaining hook 36 causes brake component frizzen 32 to protect Hold in non-trigger position;
- when positioned at non-retaining position, retaining hook releases the holding of the position to triggering end plate 33.
Electromagnet 310 is kept to obtain electric under adsorbed state, absorption driving retaining hook 36 so that the position of retaining hook 36 exists Non-retaining position;Keep the dead electricity of electromagnet 310 to be under release conditions, discharge retaining hook 36, retaining hook 36 returns back to holding position Put.The holding electromagnet core 311 of electromagnet 310 is kept to be hinged one end of retaining hook 36, the other end of retaining hook 36 is provided with Hook portion, in a free state (i.e. keep electromagnet 310 not it is electric when), retaining hook 36 is in holding position, and hook portion hook is in triggering On the sleeve pipe 42 of end plate 33;After keeping electromagnet 310 to obtain electric, electromagnet 310 is kept by keeping electromagnet core 311 to adsorb Firmly one end of retaining hook 36, so as to make retaining hook 36 rotate, and then retaining hook 36 is caused to go to non-retaining position.
The top of electromagnet core 311 is kept to be provided with groove, and radial direction is provided with a hole.The one end of retaining hook 36 can be embedded in In the groove, and by the hole, with pin come with keeping the installation of electromagnet core 311 to fix.There is a hole at the center of retaining hook 36, by with Retaining hook axle 43 is fixed in safety tongs fixed plate 19, and can be rotated around retaining hook axle 43.The other end of retaining hook 36 into hook-shaped, For hooking sleeve pipe 42.The sleeve pipe 42 is bolted on triggering end plate 33.Detector and the are detected as first position Two limit switches 38 of two position detectors are separately mounted on switch bracket, are then installed to safety tongs by switch bracket In fixed plate 19.Linear bearing 39 is arranged on triggering end plate 33.The axis of guide 40 passes through linear bearing 39, and both ends are arranged on It is oriented on axis fixing plate 41.Axis fixing plate 41 is oriented to then to be arranged in safety tongs fixed plate 19.
Retaining hook 36 is by keeping electromagnet 310 to control, shown in Fig. 9, keep electromagnet 310 be under power failure state and In release conditions, retaining hook 36 is into vertical position so that top is hook-shaped to hook 42 sleeve pipes.It is now to prevent in triggering spring 34 Active force under trigger safety tongs, so need by retaining hook 36 come keep making part frizzen 32 be currently at it is non-toggle Position.Trigger electromagnet 300 is in release conditions under powering-off state.Because sleeve pipe 42 is arranged on triggering end plate 33, so can To keep triggering end plate 33 in the case of dead electricity not upspring because of the active force of toggled spring 34, so as to keep safety tongs Non-toggle state.The effect of the axis of guide 40 and linear bearing 39 is to ensure that triggering end plate 33 can keep water under any state It is flat.
The drop preventer using electrical control also includes first position detector and/or second place detector;
The first position detector is used to detect the location of brake component frizzen 32:
- when detecting that brake component frizzen 32 is located at trigger position, first position detector output cutting equipment supplies The control signal of electrical circuit;
- when detecting that brake component frizzen 32 is located at non-trigger position, equipment is connected in detector output in first position The control signal of current supply circuit;
The second place detector is used to detect the location of locking mechanism:
- when detecting that locking mechanism is located at latched position, second place detector output cutting equipment control loop Control signal;
- when detecting that locking mechanism is located at unlocked position, equipment control loop is connected in detector output in the second place Control signal.
End plate limit switch 382 as first position detector is used for detecting safety tongs state.When triggering end plate 33 touches Encounter end plate limit switch 382, represent that safety tongs is not triggered state.When safety tongs is triggered, triggering end plate 33 is triggered Spring 34 ejects, and will not touch end plate limit switch 382, and now state is safety tongs triggering state.
As the retaining hook limit switch 381 of second place detector, for detecting the state of retaining hook 36.When retaining hook 36 When in running order (as shown in Figure 9), the lower end of retaining hook 36 can touch retaining hook limit switch 381, so that trigger switch, Now because the limitation of retaining hook 36, safety tongs will not trigger.When retaining hook 36 is in releasing orientation, retaining hook limit switch 381 are in non-triggering state (as shown in Figure 10).Equipment close or need when running into powering-off state by sequential function come Ensure that retaining hook 36 can hook triggering end plate 33, discharge trigger electromagnet iron core 301 after a loss of power to prevent trigger electromagnet 300 Cause false triggering safety tongs component 20.When equipment has just closed power supply or power-off, trigger electromagnet iron core 301 is still by corresponding Trigger electromagnet 300 keep adsorbed state, keep adsorbed state method can by switching to storage battery power supply by externally fed, from And reach the function of delay dead electricity.Then electromagnet core 311 is kept preferentially to be released so that retaining hook 36 is in work shape State, that is, triggering end plate 33 is hooked so that safety tongs component 20 can not be triggered.Cut-out absorption after a period of time has passed The power supply of the trigger electromagnet 300 of trigger electromagnet iron core 301.Because now retaining hook 36 is in running order so that safety tongs Component 20 will not be triggered.
In change case, as shown in figure 11, it is convenient to omit linear bearing and the axis of guide, so that the volume of whole device It is compacter, while the size of electromagnet triggering end plate is also decreased further, and further reduces required space.Due to Guide function is eliminated, after a long time use, it may occur that electromagnet triggers the inclined situation of end plate.
In change case, such as Figure 13, it is convenient to omit retaining hook, that is, eliminate retaining hook, retaining hook magnet, retaining hook magnet Iron core, retaining hook limit switch and switch bracket.This embodiment triggers magnet in the case of concluding will discharge triggering magnet Iron core., it is necessary to adsorb triggering pole core and wedge again by trigger electromagnet after being re-energised, and spring will be triggered Compress, it is necessary to which larger absorption affinity is realized, therefore must just select larger trigger electromagnet so that equipment volume becomes greatly. In another change case, as shown in figure 15, it can make to be directly connected in trigger electromagnet iron core as the wedge of brake component.
In change case, as shown in figure 14, the locking mechanism includes spacing electromagnet 44, brake component limited block 45; Spacing electromagnet 44 passes through the switching between adsorbed state and release conditions so that the position of brake component limited block 45 is spacing Moved between position and non-restraining position:
- when positioned at restraining position, brake component limited block 45 is to movement of the brake component frizzen 32 to trigger position Limited;
