Abstract
The utility model discloses an elevator compensation chain safety protection device which comprises a fixing piece fixed on a car base frame, a sliding rod which can be arranged on the fixing piece along the vertical direction in a sliding mode and is connected to the other end of a compensation chain, an elastic piece which is arranged between the sliding rod and the fixing piece and is used for providing elastic restoring force of the sliding rod, a switching beating plate fixed on the sliding rod, and a limiting switch which is arranged on the car base frame and can be triggered by the switching beating plate so as to stop operation of the elevator when the stress of the compensation chain is too high. When the stress of the compensation chain is too high, the elastic restoring force of the sliding rod is overcome, so that the limiting switch is triggered by the switching beating plate on the sliding rod, and the limiting switch moves, so that the elevator stops working, the chain breakage danger caused by too high stress is avoided, and the elevator accident is avoided.
Description
Technical field
the utility model relates to a kind of elevator compensation chain safety guard.
Background technology
in prior art, the elevator of compensated chain is housed when operation, if compensated chain contacts with miscellaneous part in hoistway, the stressed unexpected change of connecting bridge that causes compensated chain and sedan-chair underframe is large, if now the main power source of control system is not cut off in time, car is not out of service in time, probably cause compensated chain directly to rupture, and then may make car not enough out of control because of traction, cause serious elevator accident.
Summary of the invention
the purpose of this utility model is to provide a kind of elevator compensation chain safety guard, once compensated chain is stressed excessive, can touch limit switch, stops the elevator operation, avoids occurring elevator accident.
for achieving the above object, the technical solution adopted in the utility model is: a kind of elevator compensation chain safety guard, comprise the sedan-chair underframe, the counterweight underbeam, compensated chain on the described counterweight underbeam that one end is connected to, described elevator compensation chain safety guard also comprises the connecting element be fixed on described sedan-chair underframe, can be slidably arranged in along the vertical direction on described connecting element and connect the sliding bar that the compensated chain other end is stated in residence, be arranged between described sliding bar and described connecting element for the elastic component of this sliding bar elastic-restoring force is provided, the switch be fixed on described sliding bar re-packs, thereby be arranged on described sedan-chair underframe, can be re-packed and touch the limit switch that stops the elevator operation by described switch when excessive described compensated chain is stressed.
during concrete enforcement, in the safety return circuit of described limit switch access elevator, when described limit switch is re-packed shake-up by described switch, the safety return circuit of described elevator disconnects, and stops the elevator operation.
a kind of mode of concrete enforcement, described sliding bar adopts screw rod setting up and down, and described switch re-packs and is enclosed within on described screw rod, is combined with a pair of upper and lower setscrew nut on this screw rod, and described switch re-packs and is clamped between described upper and lower setscrew nut.
further, offer perforation on described connecting element, described screw rod can be through in described perforation along the vertical direction slidably, described elastic component adopts spring, this spring is set on described screw rod compressedly, the lower end of this spring is pushed against on described connecting element, the upper end of this spring by connecting panel be pushed against lower setscrew nut on described screw rod below.
utilization due to technique scheme; the utility model compared with prior art has following advantages: in this elevator compensation chain safety guard; elastic component is for providing the sliding bar elastic-restoring force; can make the switch on sliding bar re-pack away from limit switch; and that compensated chain occurs is stressed when excessive; the elastic-restoring force that overcomes elastic component makes the shake-up limit switch that re-packs of the switch on sliding bar; the limit switch action; thereby make elevator out of service; prevent from avoiding occurring elevator accident because of the stressed excessive danger that causes chain rupture of compensated chain.
The accompanying drawing explanation
accompanying drawing 1 is schematic diagram one of the present utility model, and wherein switch re-packs and is separated with limit switch;
accompanying drawing 2 is schematic diagram two of the present utility model, the switch shake-up limit switch that re-packs wherein, not shown counterweight underbeam and complete compensated chain in Fig. 2.
The specific embodiment
further set forth structure of the present utility model below in conjunction with accompanying drawing.
shown in Fig. 1-2, a kind of elevator compensation chain safety guard, comprise sedan-chair underframe 1, counterweight underbeam 8, compensated chain 5, connecting element 7, sliding bar 6, elastic component 4, switch re-packs 2, limit switch 3, one end of compensated chain 5 is connected on counterweight underbeam 8, the other end is connected on sliding bar 6, as shown in Figure 1, sliding bar 6 can be slidably arranged on connecting element 7 along the vertical direction, connecting element 7 is fixed on sedan-chair underframe 1, limit switch 3 also is fixed on sedan-chair underframe 1, switch re-packs and 2 is fixed on sliding bar 6, be provided with elastic component 4 between sliding bar 6 and connecting element 7, elastic component 4 is for providing sliding bar 6 elastic-restoring forces, make the switch on sliding bar 6 re-pack 2 away from limit switch 3, in Fig. 1-2, elastic component 4 adopts spring, in the position shown in the figure 1, compensated chain 5 does not have stressed or stressed normal, due to factors such as compensated chain 5 deadweights, spring is compressed, when elevator normally moves, spring has certain pre compressed magnitude.At compensated chain 5, because of unforeseen circumstances, with miscellaneous part in hoistway, contact, make the stressed increase of compensated chain 5 cause elastic component 4 aggravation compressions, the elastic-restoring force that overcomes elastic component 4 makes the 2 shake-up limit switches 3 that re-pack of the switch on sliding bar 6, as shown in Figure 2, make limit switch 3 actions, thereby make elevator out of service, prevent because of the stressed excessive danger that causes chain rupture of compensated chain 5.In the present embodiment, limit switch 3 is the non-automatic-reset switch, and in the safety return circuit of limit switch 3 access elevators, when limit switch 3 is re-packed 2 shake-up by switch, the safety return circuit of elevator disconnects, thereby the main power source of control system is cut off, and stops the elevator operation.
in Fig. 1 and 2, sliding bar 6 adopts screw rod setting up and down, and switch re-packs and 2 is enclosed within on screw rod, is combined with a pair of upper and lower setscrew nut 9 and 10 on this screw rod, switch re-packs and 2 is clamped between upper and lower setscrew nut 9 and 10, realizes switch 2 fixing at sliding bar 6 that re-pack.Offer perforation on connecting element 7, screw rod can be through in the perforation of connecting element 7 along the vertical direction slidably, the above mentions, elastic component 4 adopts spring, this spring is set on screw rod compressedly, the lower end of this spring is pushed against on connecting element 7, the upper end of this spring by connecting panel 11 be pushed against lower setscrew nut 10 on screw rod below.
in this elevator compensation chain safety guard, stressed excessive at compensated chain 5, while making the amount of compression of elastic component 4 sharply become large; being loaded on switch on sliding bar 6 re-packs and 2 can directly trigger limit switch 3; thereby the main power source of control system is cut off, stops the elevator operation, avoid occurring elevator accident.When design flexibility part 4, should consider that compensated chain 5 deadweights can make it that certain pre compressed magnitude is arranged.
