By means of the leveling device, the elevator can just stop at the position of a floor door when a safety gear is used for braking, passengers can leave the elevator quickly and safely, and life and property safety of the passengers can be guaranteed to the largest extent.
Description
Technical field
The present invention relates to a kind of elevator emergency brake leveling device.
Background technology
In order when danger appears in elevator, to rescue the passenger of the inside smoothly, the product of some moulding has been arranged in the market.But, in those products, all be the braking that utilizes safety tongs generally, cab stops in orbit the most at last, succours the passenger then.In this case, cab may stop any position in orbit, can give so afterwards relief and passenger's personal safety stay very big potential safety hazard.Such as, in the braking of using safety tongs, cab is rested on the centre of floor and floor, the passenger of this moment is panic at heart, if at this moment the cab door is opened, squeezing outward and run hurriedly that can be without the least hesitation drops on the nearest floor possibly so just have, even directly drop to can the gap between floor door and cab door bottom the hoistway and loss of life.Therefore, this only is also to have potential safety hazard by the mode that safety tongs is braked.
Summary of the invention
The purpose of this invention is to provide a kind of elevator emergency brake leveling device, it can be when safety tongs be braked, guarantee that elevator just is parked in floor door place, allow the passenger leave elevator quickly and safely, thereby ensured the safety of passengers' lives and properties to a large extent.
The object of the present invention is achieved like this:
A kind of elevator emergency brake leveling device, it comprises base, is arranged with a plurality of chutes on the base, be provided with bumping post in each chute, bumping post one end is provided with the connecting rod push-pull mechanism, is connected with retracing spring and stay cord on the connecting rod push-pull mechanism, and stay cord is connected with velocity limiter pull bar on the elevator.
Above-mentioned in chute, be provided with the push-and-pull spring between bumping post and the connecting rod push-pull mechanism.
Above-mentioned base is provided with fixed pulley, and stay cord is located on the fixed pulley.
Above-mentioned base is provided with positive stop, and positive stop is used for the limiting rod push-pull mechanism, thus the distance of restriction bumping post retraction.
Above-mentioned bumping post head is circular-arc or wedge shape.
Above-mentioned chute is provided with 4, all is symmetrically distributed at the vertical and horizontal of base.
The present invention has obtained following technique effect:
Utilize the present invention when safety tongs is braked, make elevator just be parked in floor door place, allow the passenger leave elevator quickly and safely, thereby ensured the safety of passengers' lives and properties to a large extent; After accident finishes, elevator is resumed work, need not extra operation.With regard to this device came, behind the pulling car, velocity limiter resetted, and steel rope can be in relaxed state, and bumping post loses with knock hole and contacts simultaneously.Under action of reset spring, whole device just resets fully, and elevator also can normal operation.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention;
Fig. 2 is that bumping post and knock hole cooperate scheme drawing;
Fig. 3 is use diagram of circuit of the present invention;
Fig. 4 is the diagram of circuit that resets of the present invention.
The specific embodiment
Referring to Fig. 1-4, a kind of elevator emergency brake leveling device, it comprises base 8, be arranged with a plurality of chutes 9 on the base, be provided with bumping post 2 in each chute, bumping post one end is provided with connecting rod push-pull mechanism 5, is connected with retracing spring 7 and stay cord 4 on the connecting rod push-pull mechanism, and stay cord is connected with velocity limiter pull bar on the elevator.
Preferably, in chute, be provided with push-and-pull spring 3 between bumping post and the connecting rod push-pull mechanism.Described base is provided with fixed pulley 1, and stay cord is located on the fixed pulley.Described base is provided with positive stop 6, and positive stop is used for the limiting rod push-pull mechanism, thus the distance of restriction bumping post retraction.Described bumping post head is circular-arc or wedge shape.Described chute is provided with 4, all is symmetrically distributed at the vertical and horizontal of base.
This mechanism installs and underbeam both sides, car bottom, and wherein knock hole 10 is positioned at the guide rail both sides.Radical function is when safety tongs is braked, and makes elevator just be parked in floor door place, allows the passenger leave elevator quickly and safely, thereby has ensured the safety of passengers' lives and properties to a large extent.
The described velocity limiter pull bar that can promote when elevator emergency brake makes the safety tongs action, and the lifting of velocity limiter pull bar can spur and be attached thereto the steel rope 4 that connects, and steel rope 4 pulling connecting rod mechanisms are released bumping post 2, promote bumping post 2 and move axially 200mm.The intermediate bar of connecting rod push-pull mechanism is long to be 360mm, and two side levers are long to be 197mm, and diameter all is 18mm, is connected by the d=8 pivot pin between bar and bar.The Elevator landing function is mainly thrown knock hole 10 into by bumping post 2 and is realized under thrust.
The rated load of setting elevator is 800kg, because counterweight weight equals half that car weight adds rated load, calculates with 1000N so the static weight that each bumping post will carry is 100kg().The moment of flat bed is rigid shock, and as prescribed requires car speed at this moment less than 0.63m/s, is that 0.63m/s designs so select velocity of impact.Select bumping post to be of a size of 50mm * 30mm * 495mm as calculated, the live load when getting bumping post 2 and being hit is 2130N.
Can accurately enter the knock hole trouble free service in order to ensure bumping post 2, design to the bumping post top end part has following embodiment: one is being parallel on the plane of gate, process a bigger radian on the top, the speed of restriction bumping post 2 car when entering knock hole prevents from that velocity of impact is excessive to damage; Two on horizontal surface, and column cap is arranged to wedge shape for four jiaos, increases to squeeze into the preceding friction force of knock hole, plays buffer action; The upper and lower surface intensive treatment on three pairs of bumping post 2 tops.
Thrust spring 3 mainly plays a part to promote bumping post 2, has played booster action when device resets.Longer in view of spring, select the dual spring structure for use, when avoiding unstability, also increased the thrust to bumping post 2.When device was started working, thrust spring promotion bumping post 2 made its top prop up track and be in compressive state all the time before bumping post enters knock hole under the effect of connecting rod.When bumping post 2 enters knock hole, can give bumping post 2 with than high acceleration a, can enter knock hole in the short period of time.
After accident finishes, elevator is resumed work, need not extra operation.Concerning the elevator in modern times, the action that elevator is resumed work adopt is control motor pulling car.With regard to this device came, behind the pulling car, velocity limiter resetted, and steel rope can be in relaxed state, and bumping post loses with knock hole and contacts simultaneously.Under action of reset spring, whole device just resets fully, and elevator also can normal operation.
