Description
Technical field
The utility model belongs to the Anti-isenagage structure technical field of elevator door.
Background technology
Elevator door comprises the layer door (being also Room door) being contained in well entrance stop place, and is arranged on the car door of car entrance.Car door mainly comprises the parts such as bank on gate, door machine device, lift-cabin door board, safety device and car door sill, and lift-cabin door board hangs and is installed on gate on bank, the lower end of lift-cabin door board and car door sill bearing fit; Layer door mainly comprises bank on layer door, the parts such as layer door board, door lock mechanism, self-closing device, landing sill, and layer door board hangs and be installed on layer door on bank, the lower end of lift-cabin door board and car door sill bearing fit.When Elevator landing, door machine device on gate starts, door cutter (executive item of door machine device) by with the coordinating of layer Novel door lock mechanism for door, make gate that layer door can be driven move, thus elevator door is opened or closedown.
The lower end of above-mentioned (layer door/car) door-plate is with gate guide shoe (also referred to as door slide block), and gate guide shoe coordinates with the guide groove on (layer door/car) sill, thus realizes the bearing fit of door-plate and sill.As shown in Figure 1 and Figure 2, elevator door mouth is provided with left-hand door plate LD and right flank RD to prior art, the top of left-hand door plate LD and right door-plate RD respectively with the connection of the respective connecting panel 400 of hoistway door device.In addition, in left-hand door plate LD and right door-plate RD bottom with gate guide shoe 100, and form sill 200 in bottom, layer doorway, embed in guide groove 210 to make above-mentioned gate guide shoe 100.Therefore, as needs opening and closing left-hand door plate LD and right door-plate RD, by the driving of connecting panel 400, gate guide shoe 100 guide groove 210 slide-and-guide thus complete on-off action.The shortcoming of such scheme is: 1. on the one hand, installs or in use procedure, when left-hand door plate LD and right door-plate RD is subject to abnormal impact, larger distortion can occur, gate guide shoe 100 can be departed from from guide groove 210, cause elevator safety accident at elevator.2. on the other hand, after elevator uses the long period, gate guide shoe 100 weares and teares gradually in guide groove 210, and gate guide shoe 100 and guide groove 210 gap increase gradually, increase the risk that gate guide shoe 100 takes off groove especially.
Utility model content
The utility model is intended to provide a kind of elevator door groove separation preventing device preventing gate guide shoe and sill guide groove from departing from.
Patent formula: be sill below elevator door, with guide groove on sill, the gate guide shoe of door-plate lower end is positioned at this guide groove,
This patent elevator door groove separation preventing device, comprise and can to move along with door-plate thus at the block of the without hindrance movement in guide groove place, this block is divided into the connecting portion vertically inserting guide groove, and the hook portion be laterally positioned at below guide groove, this connecting portion is connected with gate guide shoe or door-plate, and the width in hook portion is greater than the groove width of guide groove.
Beneficial effect: the connecting portion of this block inserts direct in guide groove and door-plate, or be indirectly connected with door-plate (passing through gate guide shoe), hook portion is positioned at below guide groove and width is greater than guide groove groove width, therefore, when door-plate be subject to external force or gate guide shoe wearing and tearing, cause gate guide shoe to have departing from the trend of guide groove time, hook portion can be hooked on below sill, prevents gate guide shoe from departing from guide groove, and then the safety misadventure avoiding appearance to cause because door-plate departs from guiding.
Further, described sill stop comprises L shape block or T-shaped block, optionally selects, and as certain class elevator door almost only bears unidirectional impulsive force, can consider to use L shape block; As certain class elevator door can often bear two-way impulsive force, can consider to use T-shaped block.
Further, " one " word portion of described T-shaped block is hook portion, " I " word position connecting portion, or the split one-body molded with connecting portion of this hook portion is connected, split connects is convenient to the assembling of T-shaped block, and one-body molded, decrease the connecting joint of T-shaped block self, intensity is higher.
Further, described L shape block galianconism portion is hook portion, and long-armed portion is connecting portion, or the split one-body molded with connecting portion of this hook portion is connected, and split connects is convenient to the assembling of L shape block, and one-body molded, decrease the connecting joint of L shape block self, intensity is higher.
Further, described split connects for bolt connection or welding or rivets, and this kind of mode that is fixedly connected with connects more firm.
Further, described elevator door groove separation preventing device can be used for landing sill or car sill.
The utility model additionally provides a kind of sill, this sill designs for above-mentioned elevator door groove separation preventing device, ensure that groove separation preventing device carries out without hindrance movement in this sill guide groove, and by making gate guide shoe to depart from guide groove to the stop in block hook portion below sill.
Patent formula: described guide groove is for vertically to run through sill in the stroke range of gate guide shoe and block connecting portion, and the groove width of guide groove is less than the width in block hook portion.
Beneficial effect: the stroke range of gate guide shoe and block connecting portion is determined by connected door-plate stroke range (also can claim stroke distances), as door-plate moves 1m, the gate guide shoe be connected with this door-plate and block then also mobile 1m in guide groove, on the one hand, guide groove in the stroke range of gate guide shoe and block connecting portion for vertically to run through sill, therefore gate guide shoe and block connecting portion can carry out without hindrance movement along with door-plate moves in guide groove, the groove width of guide groove is less than block hook portion width, make to be formed block hook portion below sill to stop, hook portion can not from guide groove prolapse upwards, on the other hand, this sill guide groove compares traditional guide groove with the end, and the situation that the foreign material such as dregs block gate guide shoe or block can not occur.
