Detailed description of the invention
structure of the present invention is set forth further below in conjunction with accompanying drawing.
shown in Fig. 1-3, a kind of elevator compensation chain chain breakage protection device, comprise the support 4 be fixed on the pit of elevator, be arranged on the guide 1 on support 4, there is the supporting parts 2 in the support space 24 opened wide upward, be arranged between supporting parts 2 and the pit of elevator for providing the elastic component 3 of this supporting parts 2 elastic-restoring force upwards, to be contained on support 4 and to be oppositely arranged on emission sensor 5 and the receiving sensor 6 on supporting parts 2 both sides, controller 7, in FIG, elastic component 3 adopts spring, spring is vertically arranged, spring has two, two ends bottom two corresponding supporting parts 2 of spring difference, here spring is arranged between supporting parts 2 and the pit of elevator.In other embodiment, elastic component also can be arranged between supporting parts and support, as long as elastic component can be allowed to provide elastic-restoring force upwards to support supporting parts.In Fig. 1-2, supporting parts 2 comprises bottom 21, be arranged on the vertical sides f 22 on 21 both sides bottom this, to be arranged on bottom this 21 below baffle plate 23, form the support space 24 opened wide between bottom 21 and the vertical sides f 22 on both sides upward, this support space 24 is for holding the compensated chain of fracture.The shape of supporting parts 2 can have multiple, for example adopts the arc shown in Fig. 1, and namely the bottom 21 of supporting parts 2, vertical sides f 22 are all in the arc arched upward down.Guide 1 has the guide space 13 of opening wide down, and this guide space 13 is for passing for compensated chain, thus guide 1 can guide the movement of compensated chain.In Fig. 1-2, guide adopts roller to lead, and can reduce friction like this, reduces the resistance of compensated chain movement.Specifically, guide 1 comprises and is arranged on horizontal guide sheave 11 on support 4 and a pair vertical track adjusting wheel 12, the wheel axial line of horizontal guide sheave 11 is horizontally disposed with, the wheel axial line of vertical track adjusting wheel 12 is vertically arranged, a pair vertical track adjusting wheel 12 lays respectively at the both sides of supporting parts 2, horizontal guide sheave 11 is positioned at the top of a pair vertical track adjusting wheel 12, and be between a pair vertical track adjusting wheel 12, horizontal guide sheave 11, a pair vertical track adjusting wheel 12 is around forming the guide space 13 of opening wide down, such a pair vertical track adjusting wheel 12 can lead to the both sides of compensated chain, horizontal guide sheave 11 can lead to above compensated chain, unlimited below guide space 13, such compensated chain can be made to rupture after enter the support space 24 of supporting parts 2.Normally work at compensated chain, namely when compensated chain is in normal condition, as shown in Figure 1-2, rely on elastic component 3 elastic-restoring force upwards, the top of the vertical sides f 22 on supporting parts 2 both sides is inserted in guide space 13, support space 24 leads directly to guide space 13 phase, compensated chain is through guide space 13, in fact, support space 24 and guide space 13 together define the knee-action scope of compensated chain, compensated chain can move in guide space 13 or support space 24, but can not contact with the bottom 21 of supporting parts 2, signal path now between emission sensor 5 and receiving sensor 6 is unimpeded, then elevator can normally run.Once compensated chain ruptures, the compensated chain then disconnected can be sagging due to Action of Gravity Field, the compensated chain disconnected can drop down onto in the support space 24 of supporting parts 2, compressing supporting parts 2, this supporting parts 2 compression elastic piece 3, namely the elastic-restoring force overcoming elastic component 3 moves down, and now the baffle plate 23 of supporting parts 2 is blocked between emission sensor 5 and receiving sensor 6, thus blocks the signal path between emission sensor 5 and receiving sensor 6.Once signal path is blocked; as shown in Figure 3; controller 7 can detect exception; controller 7 can take immediate measure locking breakdown signal, exports folder rope signal 8, clamping traction steel-cable to wire holder; and export stopping elevator run signal 9; stop ladder protection in time, avoid car downslide out of control, prevent safety misadventure.
in Fig. 1-2, in order to each functional component can be supported easily, support 4 comprises the first carrier unit 41, second carrier unit 42, 3rd carrier unit 43, 4th carrier unit 44, first carrier unit 41, second carrier unit 42 is all fixed on the pit of elevator, and lay respectively at the both sides of supporting parts 2, the two ends of the wheel shaft of horizontal guide sheave 11 are arranged on the 3rd carrier unit 43 respectively, on 4th carrier unit 44, in fig. 2, the wheel shaft two ends of a vertical track adjusting wheel 12 are arranged on the top of the first carrier unit 41 respectively, on 3rd carrier unit 43, the wheel shaft two ends of another vertical track adjusting wheel 12 are arranged on the top of the second carrier unit 42 respectively, on 4th carrier unit 44, complete the setting of guide 1 like this.The bottom of the first carrier unit 41, second carrier unit 42 is separately installed with emission sensor 5 and receiving sensor 6; like this once compensated chain ruptures; then falling to after in supporting parts; compressing supporting parts moves down; stop the signal path between emission sensor 5 and receiving sensor 6, control clamping hoist ropes by controller in time and carry out power-off to stop ladder protection.
this elevator compensation chain chain breakage protection device, structure is simple, easy for installation, compensated chain guiding is combined together with detection, can detect compensated chain fracture in any case and implement protection, substantially increase the safety that elevator runs.When after compensated chain fracture, control elevator in time and stop, the generation of minimizing accident.
