Specific embodiment
It referring to Fig.1 and Fig. 4, is a kind of accidental movement of elevator cage protective device disclosed by the utility model, wherein elevator Including traction machine 1, directive wheel 12, the carriage 13 moved up and down in hoistway 10, chain 14, wirerope 16 and counterweight 15 are compensated, Wirerope 16 is singly wound on the traction sheave 11 of directive wheel 12 and traction machine 1,13 top of one end connection carriage of wirerope 16, another 15 top of end connection counterweight, one end of compensation chain 14 connect 15 bottom of counterweight, and the other end connects 13 bottom of carriage.
The accidental movement of elevator cage protective device, including leveling inductor 2 and shutdown inductor 3 and opposite setting Four support rods 6 and two sets of driving assemblies in 13 top two sides of carriage and/or two sides of the bottom.Every set driving assembly respectively drives Every group of two support rods 6 make linear extension or contractile motion in the horizontal direction simultaneously, on 10 side wall of hoistway where carriage 13 The opposite duct 9 offered corresponding to four support rods 6, the driving assembly are controlled by leveling inductor 2 and shutdown inductor 3, When leveling inductor 2 senses that carriage 13 is in leveling, driving assembly drives support rod 6 to stretch out so that support rod 6 protrudes into hole Mechanical support is carried out to carriage 13 in road 9, the driving assembly driving support rod 6 when shutdown inductor 3 senses that elevator door is closed Recycling is so that support rod 6 leaves in duct 9.Mechanical support can be carried out to carriage 13 in Elevator landing by above-mentioned setting, It can be avoided carriage 13 and accidental movement occur in door opening state, protect the safety of passenger.
More specifically, being installed for convenience to support rod 6 and driving assembly, at the top and/or bottom of carriage 13 The rack 5 of rectangular frame formula is fixedly mounted in portion, and two groups of support rods 6 are separately positioned on 5 inside two sides of rack, and rack 5 is opposite Two sides respectively open up there are two access hole 51 for support rod 6 stretch out or recycle.Every group of driving assembly, which includes two, electronic to be pushed away Bar 7, two electric pushrods 7 are arranged between every group of two support rods 6, and are fixed on 5 bottom of rack, each electric pushrod 7 are fixedly connected with one end of support rod 6 respectively.
With reference to Fig. 2, as another preferred example, 8 generation of two-way hydraulic cylinder is can be used in two electric pushrods 7 It replaces, the hydraulic cylinder of two-way hydraulic cylinder 8 is respectively connect with support rod 6, so as to drive every group of two support rods 6 simultaneously simultaneously Protruding access hole 51 is inwardly contracted in rack 5 simultaneously.
It should be noted that in order to avoid influencing the operation of counterweight 15, the direction of motion and the counterweight of support rod 6 are staggered.
In conjunction with Fig. 3, once misfunctioning of brake, carriage 13 is needed through four 6 mechanical supports of support rod in elevator shaft 10 Interior, support rod 6 will receive the power of carriage 13 upwardly or downwardly at this time, it is therefore desirable to reinforce support rod 6, thus in machine The bottom of frame 5, and it is fixedly installed with fixing sleeve 61 respectively on the movement line of each support rod 6, fixing sleeve 61 is according to branch The cross sectional shape of strut 6 is determined selection square sleeve or round set, support rod 6 are fixed set 61 and are firmly locked in rack 5 Surface, and can guarantee that support rod 6 linearly moves.
When elevator runs to leveling, leveling inductor 2 sends an electric signal to central controller 11 at this time, in It entreats controller 11 to control electric pushrod 7 or two-way hydraulic cylinder 8 to release support rod 6 outside rack 5, support rod 6 is inserted respectively into In the corresponding duct 9 of 10 inner wall of hoistway, to complete the support to entire carriage 13;After completely closing for carriage 13, close the door Inductor 3, which is felt to central controller 11, sends an electric signal, and central controller 11 controls electric pushrod 7 or two-way hydraulic cylinder 8 are recycled to support rod 6 in rack 5, and after support rod 6 leaves duct 9, elevator can continue to run.
In order to stable support rod 6 is inserted into duct 9, is provided with pressure sensing on the end face of support rod 6 Device 4, when support rod 6 protrudes into duct 9, and the end face in the end face of support rod 6 and duct 9 contradicts, pressure sensor 4 will Signal is sent to central controller 11, and central controller 11 controls electric pushrod 7 or 8 stopping of two-way hydraulic cylinder movement.
The protective device of the utility model, which belongs in elevator safety technology, occurs accident in door opening state for carriage 13 Mobile prophylactic device guarantees carriage 13 in door opening state, carriage 13 is by stable branch by way of mechanical support Accidental movement occurs as carriage 13 in door opening state for support and the huge injury caused by passenger so as to greatly reduce Risk.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical Within novel protection scope.
