Abstract
The utility model relates to an automatic drop-proof apparatus for elevator to vertically transport materials in companies and construction sites. This apparatus comprises a pull rod 2, a control rope 3, a pulley 4, a spring pull rod 5, a spring 6, a middle frame 7, a lingual rod 8, a sliding way 10 and a guiding axis. When any section of the steel rope is broken, the control rope 3 is no longer subject to 77 the pulling force. The spring 6 pops up the lingual rod 8 and makes the lingual rod 8 hang on the web-member rod of the boring tower in order to prevent the suspension cage from dropping. This apparatus is simple in structure, convenient to install and small in volume, and needs no manual control and adjustment after it is installed. And this apparatus is dust proof and good at preventing from rain, and this apparatus is an ideal drop-proof apparatus for elevator suspension cage.
Description
The utility model relates to the automatic anti-fall device of elevator of vertical transport materials such as a kind of factory and building ground, is particularly useful for cage formula elevator.
Existing elevator craning cage anti-fall device has coupling type, bolt-type and track brake formula.Whether preceding two kinds all is to adopt manual type, and the operator must hig diligence, will link up with before the elevator operation or latch has placed off working state, otherwise will cause the accident generation, and these two kinds of devices can not prevent falling in the cage operational process.The track brake formula is by clamp the clamping action of guide rail to be made cage falling-proof, this device only is applicable to a kind of guide rail, guide rail to other shape all can not be suitable for, and manufacturing, installation quality to guide rail are strict, also there is certain requirement in gap to cage track adjusting wheel and guide rail, and the structure more complicated, and volume is big, when mechanism is malfunctioning, be not easy to find, and dustproof, rain proofness is relatively poor.
In view of above existing shortcoming, the purpose of this utility model is that a kind of no-man control will be provided, and is simple in structure, is applicable to any guide rail, elevator operation and quiescence all played the automatic anti-fall device of elevator of anti-fall effect.
The utility model is achieved in that mainly and is made of positioning tie bar 2, tricing line 3, pulley 4, spring pull bar 5, spring 6, middle frame 7, tongue bar 8, slide rail 10 and the axis of guide 11.One end of middle frame 7 has tapered jaw, and slide rail 10 is fixed in the channel-section steel, and the axis of guide 11 is contained in the chute of slide rail 10.
Be elaborated below in conjunction with accompanying drawing.
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is a cutaway view of the present utility model.
Among Fig. 1,2, the 1st, steel rope is connected with the radius stay 2 at cage 9 tops, and tricing line 3 is connected with the below of radius stay 2.Pulley 4 is contained on the pulley yoke that is fixed in the channel-section steel.One end of spring pull bar 5 is connected with tricing line 3, and spring 6 is housed, and the other end is connected with middle frame 7, and tongue bar 8 connects together by the axis of guide 11 and middle frame 7, and the axis of guide 11 can be reciprocating along the slide rail 10 that is fixed on the channel-section steel.One end of middle frame 7 has tapered jaw.
When steel rope 1 is raised, drives on the positioning tie bar 2 and move.Drive simultaneously on the tricing line 3 and move, the force direction that is subjected to by pulley 4 back change tricing line 3 makes it become horizontal motion.With tricing line 3 one end bonded assembly spring pull bars 5 also while horizontal motion.At this moment the axis of guide 11, spring pull bar 5, middle frame 7 and tongue bar 8 are simultaneously along slide rail 10 parallel motions, and spring 6 is compressed, and the cage of elevator drive at this moment is in normal working.When the disconnected rope of steel rope 1 any one generation, cage 9 falls fast, and tricing line 3 no longer is subjected to the pulling force of steel rope 1 simultaneously, and spring 6 outwards ejects tongue bar 8, middle frame 7 together, makes tongue bar 8 rapid loads on the web member of derrick, thereby has prevented falling of cage.When steel rope 1 is normal, when tricing line 3 or its fixed end were deviate from, spring 6 ejected tongue bar 8 levels.If cage 9 is for descending this moment, then cage can stop to fall, and steel rope 1 is loose can not to cause danger.If then the end face of tongue bar 8 can bump on derrick geometry spare in order to rise this moment for cage 9, make tongue bar 8 go out the gripping power of middle frame 7 one end tapered jaws and sagging (seeing that Fig. 2 analyses and observe) plays safety effect, also indicate that this device is a failure state, answers out-of-service inspection simultaneously.
This device has simple in structure, and is easy for installation, and volume is little, and reliable in action can be used for the guide rail of Any shape, need not manual control, need not adjust after the installation, can not cause accident during inefficacy, and the inefficacy Status Flag is arranged.Because it is this device is installed in the channel-section steel, dustproof during outdoor application, rain proofness is better.Reliable through this device performance on probation, every index all reaches requirement, is present comparatively ideal cage falling-proof device.
Claims (3)
1, a kind of automatic anti-fall device of elevator that comprises steel rope 1, cage 9 is characterized in that being made of positioning tie bar 2, tricing line 3, pulley 4, spring pull bar 5, spring 6, middle frame 7, tongue bar 8, slide rail 10 and the axis of guide 11.
2, device according to claim 1 is characterized in that an end of middle frame 7 has a tapered jaw.
3, device according to claim 1 is characterized in that slide rail 10 is fixed in the channel-section steel, and the axis of guide 11 is contained in the chute of slide rail 10.
