Description
Technical field
It is especially a kind of to be used to prevent the protection device of used during elevator falling the present invention relates to elevator machine manufacturing technology field.
Background technology
As increasing skyscraper occurs, elevator applications are more commonly.But safety problem is severe, accident increases
It is many, the particularly falling accident of cage and personnel.Many elevators do not have fall protection equipment, and reason is existing fall arrest
Protection device is complicated and cost is high, poor durability, it is difficult to safeguard.One kind that the present invention is designed aiming at these problems
Elevator shaft bottom fall protection equipment, the device of buffering land with high safety.
The content of the invention
Problem to be solved by this invention is to provide a kind of elevator fall protection equipment, to solve during existing used during elevator falling
The problem of buffer protection.
In order to solve the above problems, the technical scheme is that：This elevator fall protection equipment includes flexible buffer
Layer, the supple buffer layer bottom is provided with dividing plate, and the dividing plate bottom is provided with the multiple springs for erectting setting, the spring bottom
It is fixed with bearing plate；The bearing plate is hanging in the top on elevator shaft bottom floor by steel wire rope, and the steel wire rope is across crossbeam
It is connected with pouring weight；The crossbeam and the pouring weight are arranged in the vertical slideway that elevator wall is opened up, the vertical slideway two
Neck is provided with the wall of side, the pouring weight centre is horizontal two locking feather keys corresponding with the neck, two lockings
Feather key is connected by an elastic component.
In above-mentioned technical proposal, more specifically scheme can be：The steel wire rope is arranged at the load-bearing laterally side by side
The bottom of plate.
Further：The steel wire rope is buckled with the pouring weight by hanger or dop is connected.
Further：Opening up at least two on the side of the vertical slideway has the neck of difference in height.
Further：The supple buffer layer is made up of hair foamed material；The dividing plate using steel plate or aluminium alloy plate or
Armoured concrete slab is made, and the bearing plate is made of steel plate or aluminium alloy plate or armoured concrete slab.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
Baffle-box and steel wire rope and pouring weight three layers of cushion of formation of this elevator fall protection equipment, i.e., in baffle-box
The kinetic energy conversion layer that supple buffer layer, spring deceleration layer and steel wire rope and pouring weight are constituted, three layers of buffering, is formd very to cage
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 be delayed
The cage slid is rushed, finally realizes that cage is safe and reliable and gently lands, considerably increase buffering dynamics；Locking in pouring weight
Feather key prevents pouring weight falls to forming elevator from rebounding again with being provided with neck on the wall of elevator both sides.This elevator fall arrest is protected
Protection unit is safe and reliable, simple in construction, convenient to manufacture, and reduces cost.
Brief description of the drawings
Fig. 1 is the front view of the embodiment of the present invention one；
Fig. 2 is Fig. 1 A-A sectional views；
Fig. 3 is the structural representation that the pouring weight of the embodiment of the present invention one is connected with steel wire rope；
Fig. 4 is the structural representation that the pouring weight of the embodiment of the present invention two is connected with steel wire rope.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings：
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, here
Supple buffer layer 1 is made up of hair foamed material, realizes flexible buffer, prevents the casualties that drops, while the electricity fallen to high speed
Elevator car is tentatively buffered.The bottom of supple buffer layer 1 is provided with dividing plate 4, and the bottom of dividing plate 4 is provided with the multiple springs 2 erect and set, this
In spring 2 have 7 rows, often row have 7 totally 49, to strengthen buffering dynamics.The bottom of spring 2 is fixed with bearing plate 5, and dividing plate 4 is
Armored concrete dividing plate, bearing plate 5 is armored concrete bearing plate, to strengthen holding power.This part is deceleration layer, at a high speed
The further deceleration buffer of cage of whereabouts, while the pouring weight 31 that gently energy is gone to by following steel wire rope 33.Hold
The bottom of weight plate 5 is hanging in the top on elevator shaft bottom floor 6, the two of steel wire rope 33 by 5 steel wire ropes 33 set laterally side by side
End is connected with pouring weight 31 across two crossbeams 32, and steel wire rope 33 is connected with pouring weight 31 by dop 311, and crossbeam 32 and pouring weight 31 are set
It is placed in the vertical slideway 7 that elevator wall is opened up, this part is kinetic energy conversion layer, by the tensioning of steel wire rope 33, quick
The cage kinetic energy of whereabouts is transformed on pouring weight 31, could effectively buffer the cage of landing, finally realizes that cage safely may be used
By gently landing, steel wire rope 33 passes through the suspension strut of crossbeam 32.Two necks for having difference in height are provided with the vertical two side of slideway 7
315, the upper surface of neck 315 is tilted, lower surface level, horizontal in the middle of pouring weight 31 to have two lockings corresponding with neck 315 to slide
Key 313, two locking feather keys 313 are connected by an elastic component 314, and elastic component here is also spring.Moved when pouring weight 31 rises
When moving to extreme higher position, locking feather key 313 is outwards ejected under the active force of elastic component 314, snaps into the wall 7 of elevator both sides
On neck 315, prevent pouring weight 31 falls to forming elevator from rebounding again.This elevator fall protection equipment is right using three layers of buffering
Cage forms good buffer protection, at the same it is safe and reliable, it is simple in construction, it is convenient to manufacture, reduce cost.
Embodiment two：
The steel wire rope of this elevator fall protection equipment can also be buckled by hanger with pouring weight and is connected, such as Fig. 4, to ensure it
Stable connection, other structures such as embodiment one.Dividing plate can also be made of steel plate or aluminium alloy plate, and bearing plate can also be adopted
It is made of steel plate or aluminium alloy plate.Spring number can also be 1 to 500 any one numerical value, the quantity of steel wire rope can also be 1 to
100 any one numerical value.
