According to the elevator falling prevention and protection device disclosed by the invention, a buffer protection problem can be solved when an existing elevator falls.
Description
Technical field
The present invention relates to elevator machine manufacturing technology field, especially a kind of for preventing the protection device of used during elevator falling.
Background technology
Along with increasing skyscraper occurs, elevator applications is more commonly.But safety problem is but severe, accident increases, particularly the falling accident of cage and personnel.A lot of elevators do not have fall protection equipment, reason to be that existing fall protection equipment structure is complex and high cost, poor durability, it is difficult to safeguard.A kind of elevator shaft bottom fall protection equipment that the present invention is aiming at these problems and designs, implements the device of safe buffering land.
Summary of the invention
Problem to be solved by this invention is to provide a kind of elevator fall protection equipment, the problem of buffer protection during to solve existing used during elevator falling.
In order to solve the problems referred to above, the technical scheme is that this elevator fall protection equipment includes supple buffer layer, be provided with dividing plate bottom described supple buffer layer, being provided with bottom described dividing plate and erect the multiple springs arranged, described spring bottom is fixed with bearing plate；Described bearing plate is unsettled above elevator shaft bottom floor by steel wire rope, and described steel wire rope strides across crossbeam and is connected to pouring weight；Described crossbeam and described pouring weight are arranged in the vertical slideway that elevator wall is offered, described vertical slideway two side has draw-in groove, horizontal in the middle of described pouring weight have two locking feather keys corresponding with described draw-in groove, and two described locking feather keys are connected by an elastic component.
In technique scheme, more specifically scheme may is that described steel wire rope is arranged at the bottom of described bearing plate laterally side by side.
Further: described steel wire rope and described pouring weight are buckled by hanger or dop is connected.
Further: offering at least two on the side of described vertical slideway has the draw-in groove of difference in height.
Further: described supple buffer layer is made for sending out foamed materials；Described dividing plate adopts steel plate or aluminium alloy plate or armoured concrete slab to make, and described bearing plate adopts steel plate or aluminium alloy plate or armoured concrete slab to make.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
The baffle-box of this elevator fall protection equipment and steel wire rope and pouring weight form three layers cushion, and the kinetic energy conversion layer that namely supple buffer layer in baffle-box, spring deceleration layer and steel wire rope and pouring weight are constituted, three layers cushions, and cage defines good buffer protection；Many steel wire ropes are arranged side by side, and the cage kinetic energy hurtled down is transformed on pouring weight, could effectively cushion the cage of landing, finally realize that cage is safe and reliable to land gently, considerably increase buffering dynamics；Locking feather key in pouring weight and the wall of elevator both sides have draw-in groove, it is prevented that pouring weight whereabouts forms elevator and again rebounds.This elevator fall protection equipment is safe and reliable, simple in construction, the convenient manufacturing, reduces cost.
Accompanying drawing explanation
Fig. 1 is the front view of the embodiment of the present invention one；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the structural representation that the embodiment of the present invention one pouring weight is connected with steel wire rope；
Fig. 4 is the structural representation that the embodiment of the present invention two pouring weight is connected with steel wire rope.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
Embodiment one:
Elevator fall protection equipment as shown in Figure 1, Figure 2, Figure 3 shows; it includes the supple buffer layer 1 on top, and supple buffer layer 1 here is made for sending out foamed materials, it is achieved flexible buffer; prevent the casualties that drops, the cage fallen at a high speed is tentatively cushioned simultaneously.Being provided with dividing plate 2 bottom supple buffer layer 1, be provided with and erect the multiple springs 2 arranged bottom dividing plate 2, spring 2 here has 7 rows, and often row has 7 totally 49, to strengthen buffering dynamics.Being fixed with bearing plate 5 bottom spring 2, dividing plate 4 is armored concrete dividing plate, and bearing plate 5 is armored concrete bearing plate, to strengthen holding power.This part is deceleration layer, to the further deceleration buffer of cage fallen at a high speed, the pouring weight 31 gently energy forwarded to by following steel wire rope 33 simultaneously.Bottom bearing plate 5,5 steel wire ropes 33 by arranging laterally side by side are unsettled above elevator shaft bottom floor 6, the two ends of steel wire rope 33 stride across two crossbeams 33 and are connected to pouring weight 31, steel wire rope 33 is connected by dop 311 with pouring weight 31, crossbeam 33 and pouring weight 31 are arranged in the vertical slideway 7 that elevator wall is offered, this part is kinetic energy conversion layer, by steel wire rope 33 stretch-draw, the cage kinetic energy hurtled down is transformed on pouring weight 31, could effectively cushion the cage of landing, finally realize that cage is safe and reliable to land gently, steel wire rope 33 is by crossbeam 32 suspension strut.Vertical slideway 7 two side has two draw-in grooves 315 having difference in height, draw-in groove 315 upper surface tilts, lower surface level, and horizontal in the middle of pouring weight 31 have two locking feather keys 313 corresponding with draw-in groove 315, two locking feather keys 313 are connected by an elastic component 314, and elastic component here is also spring.When pouring weight 31 rises and moves to extreme higher position, locking feather key 313 outwards ejects under elastic component 314 active force, snaps on the draw-in groove 315 of wall 7 of elevator both sides, it is prevented that pouring weight 31 whereabouts forms elevator and again rebounds.This elevator fall protection equipment adopts three layers buffering, and cage defines good buffer protection, simultaneously safe and reliable, simple in construction, the convenient manufacturing, reduces cost.
Embodiment two:
The steel wire rope of this elevator fall protection equipment and pouring weight can also be linked by hanger and connect, such as Fig. 4, to ensure its stable connection, and other structures such as embodiment one.Dividing plate can also adopt steel plate or aluminium alloy plate to make, and bearing plate can also adopt steel plate or aluminium alloy plate to make.Spring number can also is that 1 to 500 any one numerical value, and the quantity of steel wire rope can also be 1 to 100 any one numerical value.
