Abstract
The invention discloses an elevator lift car safety device. The elevator lift car safety device is characterized in that an interlayer which is arranged below a lift car bottom plate is included, the interlayer comprises a collision prevention bottom plate, a plurality of guide pillars which can move up and down relative to a lift car are arranged on the periphery of the collision prevention bottom plate, each guide pillar is provided with a buffer spring, explosion pull rods which enable the collision prevention bottom plate to be fixedly arranged on the lift car bottom plate are arranged between the collision prevention bottom plate and the lift car bottom plate, the interlayer is provided with safety air bags, and an accelerated speed sensor capable of detecting the abnormal change of the accelerated speed of the elevator lift car so that the explosion pull rods and explosives in the safety air bags can be detonated is arranged in the interlayer. The elevator lift car safety device overcomes the defects in the prior art and can reduce casualty accidents under the condition that steel cables are fractured.
Description
Technical field
The present invention relates to a kind of lift car safety device.
Background technology
The safety of elevator, mainly relies on rope clamp device at present.But just in case wirerope fracture, car will become free-falling body, and heavy casualty accident will occur.This type of tragedy happens occasionally.
So research and development one can play safety guard-safeguard car under wirerope crack conditions, the lift car safety device that reduces casualty accident generation is necessary.
Summary of the invention
The object of the invention is in order to overcome weak point of the prior art, provide a kind of and can under wirerope crack conditions, reduce the safe elevator lift-cabin that casualty accident occurs.
In order to achieve the above object, the present invention adopts following scheme:
A kind of lift car safety device, it is characterized in that: include the interlayer that car floor below is set, described interlayer includes crashproof base plate, on described crashproof base plate periphery, be provided with on multiple cars relatively, the guide pillar of lower movement, on described guide pillar, be provided with recoil spring, between described crashproof base plate and car floor, be provided with and crashproof base plate can be fixed on to the blast pull bar in car floor, be provided with safety air bag at described interlayer, thereby in described interlayer, be provided with the acceleration induction device that can detect explosive in lift car acceleration/accel ANOMALOUS VARIATIONS ignition blast pull bar and safety air bag.
A kind of lift car safety device as above, is characterized in that being provided with anticreep steel cable between described crashproof base plate and car floor, and described anticreep steel cable one end is fixedly connected on crashproof base plate, and the described anticreep steel cable other end is fixedly connected in car floor.
A kind of lift car safety device as above, is characterized in that being provided with anti-rebound mechanism between described crashproof base plate and car floor.
A kind of lift car safety device as above, is characterized in that described anti-rebound mechanism comprises the non-return bullet snap close being located on crashproof base plate, is provided with the lockhole corresponding with described non-return bullet snap close in described car floor.
A kind of lift car safety device as above, is characterized in that described safety air bag includes the lower safety air bag being arranged on crashproof base plate and is arranged on the upper safety air bag in car floor.
In sum, the present invention with respect to its beneficial effect of prior art is:
Lift car safety device of the present invention is in the time of lift car generation free-falling body, acceleration induction device can be ignited explosive in blast pull bar and safety air bag according to the abnormal acceleration/accel of lift car, thereby make recoil spring and safety air bag play the effect of buffering, there is the probability of great disability in the passenger in reduction car effectively, avoids occurring the consequence of passenger's death.
Brief description of the drawings
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with brief description of the drawings and detailed description of the invention, the invention will be further described:
A kind of lift car safety device as shown in Figure 1, include the interlayer 2 that car floor 1 below is set, described interlayer 2 includes crashproof base plate 21, on described crashproof base plate 21 peripheries, be provided with on multiple cars relatively, the guide pillar 22 of lower movement, on described guide pillar 22, be provided with recoil spring 23, between described crashproof base plate 21 and car floor 1, be provided with and crashproof base plate 21 can be fixed on to the blast pull bar 24 in car floor 1, be provided with safety air bag 3 at described interlayer 2, thereby in described interlayer 2, be provided with the acceleration induction device that can detect lift car acceleration/accel ANOMALOUS VARIATIONS ignition blast pull bar 24 and safety air bag 3 interior explosives.
In the present invention, between described crashproof base plate 21 and car floor 1, be provided with anticreep steel cable 4, described anticreep steel cable 4 one end are fixedly connected on crashproof base plate 21, and described anticreep steel cable 4 other ends are fixedly connected in car floor 1.
In the present invention, between described crashproof base plate 21 and car floor 1, be provided with anti-rebound mechanism 5.Wherein said anti-rebound mechanism 5 comprises the non-return bullet snap close 51 being located on crashproof base plate 21, is provided with the lockhole corresponding with described non-return bullet snap close 51 in described car floor 1.
Car of the present invention bottom adopts sandwich structure.Interlayer relies on blast pull bar to fix at ordinary times.In interlayer, there are acceleration induction device and safety air bag; in the time that acceleration induction device senses abnormal velocity variations; just start the explosive of blast pull bar and safety air bag; making has enough cushion spaces between crashproof base plate and car floor; the air bag of inflation is filled up in this cushion space the inside, to the effect that just can play buffer protection time collision on the ground.
More than show and described groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
