Description
Technical field
The present invention relates to the toeguard that a kind of elevator is used, particularly a kind of flexible toeguard that is applicable to shallow pit elevator.
Background technology
At present, the toeguard that elevator is used is installed in below the car sill, and is non-telescoping, and this kind structure design is simple, applicable to most of elevators.But when pit depth was more shallow, this kind design is meeting scratching pit ground when elevator moves to the bottom, and toeguard is damaged; Also may damage the specialized maintenance personnel in pit simultaneously, thereby traditional toeguard can not adapt to the security needs of shallow pit.
Be in " electric foot protecting plate device for vertical lift carriage " of CN200520051796.X in the patent No., a kind of design of electric foot protecting plate is disclosed, it adopts manual control to give electricity to small machine, small machine rotates, make axially move drivening rod assembly action of imput shaft by steering hardware, connecting rod assembly slides in the chute of side cover plate by pin, impels side cover plate to rotate with the axle on it.When rotating to upright position, car bottom plane, be triggered to bit switch, small machine shuts down, and toeguard is opened, and realizes the mode of protection.But structure is too complicated, be not easy to processing, and manufacturing cost is also very high; In addition in number of patent application is 200710068463.1 " foot protecting plate for telescopic cage ", mentioned telescopic toeguard adopt toeguard by upper slice and lower consist of, at upper or lower both sides, respectively establish guide groove, make lower upper part or upper slice bottom insert in the guide groove and make lower can stretch up and down.When lift car operation downwards until during bottom; or car is when being pressed onto on the energy disperser fully; lower of this toeguard touches pit ground or human body etc., and sector-meeting upwards promotes lower along guide groove under stressed effect under the toeguard, has carried out shallow pit elevator running protection.Although its structure is simple, but can not satisfy standard EN 81-1/2 " elevator manufacturing and installation safety standard " fully revises in the part about the requirement of " toeguard of indentation under normal operating condition; can manually stretch when needing " and when shallow pit, even elevator moves downwards with very little power or very low speed, touch service personnel, also can moment service personnel be damaged.
Summary of the invention
The purpose of this invention is to provide a kind of flexible toeguard, it has solved the prior art security needs that can not adapt to shallow pit that exist and the defectives such as requirement that can't satisfy standard code, compared with prior art, it is simple in structure, processing ease, installation, easy to maintenance significantly reduces cost and improves the safe reliability of using.
The technical solution adopted in the present invention is: this flexible toeguard comprises fixing base, portable plate and movable rod, its technical essential is: the top of described fixing base and portable plate is provided with the level base bar of horizontal guide slot, at the middle part of described fixing base vertical guide groove is set, be hinged on the central pin shaft of the described movable rod on the level base bar of described portable plate, vertical guide groove along described fixing base moves back and forth, horizontal guide slot by described level base bar between described fixing base and the portable plate or between the adjacent described portable plate and to be arranged on the end bearing pin of described movable rod hinged, and the end bearing pin that makes described movable rod moves back and forth along the horizontal guide slot of described level base bar, level base bar at described fixing base is hinged with the toeguard lock, and the safetied pin that matches with the latch hook of described toeguard lock is fixed on the level base bar of described portable plate.
The source switch of control elevator operation is set at described fixing base, and the switch touch panel of described source switch is fixed on the level base bar of described portable plate.
Advantage and good effect that the present invention has are: the present invention connects by movable rod between fixing base and portable plate owing to adopting, take full advantage of guide groove and the with it movement between the bearing pin on the hinged movable rod on the level base bar, so realized the folding and unfolding campaign of portable plate, thereby reached the purpose of toeguard integral telescopic.Compared with prior art, it is simple in structure, processing ease, and installation, easy to maintenance significantly reduces cost.By the latch hook of toeguard lock and the with it clutch of the safetied pin of cooperation, finish the flexible effective control of toeguard, the maintainer has been played positive protective effect, further improved the safe reliability of using.Therefore, the invention solves the prior art security needs that can not adapt to shallow pit that exist and the defectives such as requirement that can't satisfy standard code.

The specific embodiment
Describe concrete structure of the present invention in detail according to Fig. 1～3.Should comprise the parts such as fixing base 1, portable plate, movable rod 5, toeguard lock 3 and source switch 11 by flexible toeguard.Wherein the specification size and number of portable plate should arrange according to actual needs, and the present embodiment adopts three portable plate 8a, 8b, 8c.The top of fixing base 1 and portable plate 8a, 8b, 8c is provided with respectively the level base bar 2 of horizontal guide slot.For keeping level base bar 2 at a plane of movement, between portable plate 8a, 8b, 8c and level base bar 2, adjusting pad 12 is arranged.At the middle part of fixing base 1 vertical guide groove is set, be hinged on the central pin shaft 7 of the movable rod 5 on the level base bar 2 of portable plate 8a, along upper and lower the moving back and forth of vertical guide groove of fixing base 1, portable plate 8a, 8b, 8c are played the effect of guiding in the upper and lower telescopic moving of vertical direction.Between fixing base 1 and the portable plate 8a, or between adjacent activities plate 8a and the 8b, or between adjacent activities plate 8b and the 8c, horizontal guide slot by level base bar 2 and to be arranged on the end bearing pin 6 of movable rod 5 hinged, and make the end bearing pin 6 of movable rod 5 along left and right the moving back and forth of horizontal guide slot of level base bar 2, and realize carrying out spacing to portable plate 8a, 8b, 8c in the up and down telescopic moving of vertical direction by the location of end bearing pin 6 in horizontal guide slot.
For guaranteeing all portable plate 8a, 8b, the 8c state that remains retracted, be hinged with the toeguard lock 3 that utilizes triangular key to open at the level base bar 2 of fixing base 1.The safetied pin 9 that matches with the latch hook 4 of toeguard lock 3 is fixed on the level base bar 2 of portable plate 8c.After portable plate 8a, 8b, 8c contraction, namely available latch hook 4 catches on safetied pin 9, and toeguard lock 3 is in blocking.The source switch 11 of control elevator operation can be set on fixing base 1, and the switch touch panel 10 of source switch 11 is fixed on the level base bar 2 of portable plate 8c.When toeguard lock 3 is in blocking, source switch 11 closures, elevator normally moves.
During use, elevator is in normal operating condition, and all portable plate 8a, 8b, 8c are contracted in together, as shown in Figure 3, and all under the combined action of latch hook 4 and safetied pin 9, all portable plate 8a, 8b, 8c are firmly drawn in together with fixing base 1.This moment, switch contact block 10 contact source switchs 11 were confirmed elevator normally conveying people and goods.
When elevator is in inspecting state or elevator and exists fault to overhaul, adopt the special-purpose triangular key of elevator that toeguard lock 3 is opened the specialized maintenance personnel, latch hook 4 unclamps safetied pin 9, and portable plate 8a, 8b, 8c stretch out expansion downwards under Action of Gravity Field, as shown in Figure 2.Simultaneously, switch touch panel 10 leaves source switch 11, and source switch 11 cuts off, and elevator can not normally move, and has guaranteed maintainer's personal safety.Elevator reparing finishes, and the maintainer upwards promotes portable plate 8a, 8b, 8c draws in, simultaneously latch hook 4 is caught on safetied pin 9, and toeguard lock 3 is in blocking, source switch 11 closures, and elevator can recover normal operating condition.
