Abstract
The utility model relates to a landing door head board of an elevator, which has functions of guiding and falling prevention in emergency and can avoid falling of a landing door when wheels are easy to derail due to abnormal reduction. Protruded hooks simple in structures are arranged on the surface of the landing door head board and are not involved in working during normal running of an elevator (namely are free of contacting with stamped guide rail grooves on a fold board fixedly arranged on the inner side of a door head). After the elevator runs for a long time, if rims of door strap wheels or the wheels are in fault (such as in reducing ) or if the landing door is extruded by external force, the protruded hooks extending into the guide rail grooves and an emergency guiding device at the bottom of the landing door can commonly have the stopping function, namely the landing door of the elevator can be hung in the guide rail grooves on the fold plate, so that the landing (hall) door cannot fall into a shaft. The protruded hooks cannot be involved in working during normal running of the elevator but have the function of emergency falling prevention in case of failures of the wheels.
Description
Technical field
The utility model relates to the elevator door anti-drop device, relates in particular to the elevator inlay door head plate with emergent guiding anti-drop function.
Background technology
The emergent guide piece of elevator door has defined " because wearing and tearing, corrosion or cause of fire possibly cause guide piece to lose efficacy the time, should be provided with emergent guide piece layer door remained on original position " to elevator hall door in GB7588-2003 " elevator manufacturing with safety standard is installed ".And at present; The layer door guiding of most of elevator manufacturer adopts two door strap rollers and flap to realize that two door strap rollers mostly adopt cast iron and plastics as material, in use owing to wear and tear and corrosion possibly cause door strap roller wheel rim inefficacy (undergauge, size decreases); In case layer door pushed by external force; Derailing possibly occur, and then cause layer door to fall into hoistway, the personnel that cause easily injure the loss with property.
The utility model content
The utility model provides a kind of and unusual undergauge occurred at roller to above problem, when going out the situation of " rail " easily, and the elevator inlay door head plate that can avoid layer door to drop.
The technical scheme of the utility model is: a said door plate is provided with a pair of door strap roller; Between a pair of door strap roller, be provided with at least one gib head protruding hook down on the said door plate plate face; The lower edge height of said gib head is lower than the lower edge height of said door strap roller; The distance of a gib head inner edge and a said door plate is greater than the distance of said door strap roller lateral surface to a door plate.
Said protruding hook is the protruding hook of sheet that stamping-out goes out on a door plate.
Said protruding hook is the threaded bending bar of an afterbody; A said door plate is provided with upright strip shape groove; Said bending bar afterbody passes said strip shape groove, adopts nut to be fastenedly connected the screw thread of said bending bar afterbody at the back side of strip shape groove.
The utility model is provided with protruding hook on a door plate plate face, it is simple in structure, when normal operation, stay out of work (not with flap that door head inboard fixedly installs on the guide-track groove that stamps out any contact arranged).After long-time running; If door strap roller wheel rim or roller itself lost efficacy when (like undergauge); If layer door receives the situation of external force extruding; Stretch into the protruding hook of guide-track groove and the emergent guide piece of layer door bottom and can play barrier effect jointly, promptly hang over elevator door in the guide-track groove on the flap, avoid elevator layer (Room) door in hoistway, to fall.Protruding being hooked in when elevator normally moves of the utility model stays out of work, loses efficacy in case roller occurs, then can play the effect of emergent anticreep.

The specific embodiment
The utility model is shown in Fig. 1-5: a said door plate 1 is provided with a pair of door strap roller 2; Between a pair of door strap roller 2, be provided with at least one gib head protruding hook down on a said door plate 1 plate face; The lower edge height of said gib head is lower than the lower edge height of said door strap roller 2; The distance of a gib head inner edge and a said door plate 1 is greater than the distance of said door strap roller 2 lateral surfaces to a door plate 1.
First kind of embodiment of the utility model such as Fig. 1-3, said protruding hook is the protruding hook 11 of sheet that stamping-out goes out on a door plate 1.Because a most of door plate 1 adopt the sheet material machine-shapings, so just can add man-hour at sheet material, direct stamping-out goes out the protruding hook 11 of sheet, demonstrates behind the stamping-out space 110 behind the stamping-out that stays on a door plate 1 body among Fig. 3; The part of protruding forward behind the stamping-out becomes the protruding hook 11 of sheet; It has stretched in the guide-track groove 41, not with flap that door head inboard fixedly installs on the guide-track groove that stamps out any contact arranged, when elevator normally moves, stay out of work, lost efficacy in case roller occurs, then can play the effect of emergent anticreep.
Second kind of embodiment of the utility model is with first kind of embodiment difference that shown in Fig. 4 ~ 5 said protruding hook is the threaded bending bar 12 of an afterbody; A said door plate 1 is provided with upright strip shape groove 120; Said bending bar 12 afterbodys pass said strip shape groove 120, adopt nut 121 to be fastenedly connected the screw thread of said bending bar 12 afterbodys at the back side of strip shape groove 120.Bending bar 12 heads stretch out in the guide-track groove 41, not with flap that door head inboard fixedly installs on the guide-track groove that stamps out any contact arranged, when elevator normally moves, stay out of work, lost efficacy in case roller occurs, then can play the effect of emergent anticreep.
The principle of work of the utility model is: when roller 2 inefficacies (during undergauge); If elevator door 3 is received external force and is pushed; Roller 2 can come off from guide rail 41, but because the utility model stretches into the effect of the protruding hook in the guide-track groove 42, makes that elevator door 3 is unlikely in hoistway, to fall.Guaranteed the safety of lives and properties, easy operating is implemented again.
