Description
Technical field
The utility model relates to a kind of elevator safety fender guard, belongs to the elevator field.
Background technology
Along with the development of society, increasing people has moved into building from one-storey house, because the height of building is higher, can be equipped with elevator usually.Because elevator of the prior art all is to adopt the rope car that plays, and controls the upper and lower of elevator through motor.Owing to can rub between rope and the pulley, in use unavoidably accident can appear, in case the fracture of the rope of elevator is easy to cause the Personal Risk so.Therefore be widely used because rope elevator cost is low; Yet the rate of meeting accident of rope elevator also obviously increases in widespread use; The rope elevator is easy to occur the terraced phenomenon of card even occurs weighing down terraced when meeting with power failure suddenly; Though the rope elevator has been installed falling proof device at present, what these falling proof devices had when running into accident or having a power failure suddenly can't use.
The utility model content
The purpose of the utility model is, a kind of elevator safety fender guard is provided, and it can prevent effectively that elevator from terraced accident taking place to weigh down, personnel's safety in the protection elevator, and the utility model need not electricity consumption, even power down mode also can normal operation.
The technical scheme of the utility model: a kind of elevator safety fender guard; Comprise dash plate, recoil spring and spring perch; Two symmetrical faces of the bottom of elevator are provided with the dash plate of symmetrical distribution; The top of dash plate is hinged through the inwall of hinge and elevator, is provided with recoil spring between the inwall of dash plate and elevator, and the two ends of recoil spring are separately fixed on the spring perch of being located on dash plate and the elevator; Be provided with car in the elevator, the bottom of car is provided with taper deceleration piece.When fracture took place the rope of elevator, car can descend rapidly, eliminated through the impulsive force that dash plate is downward with car gradually, finally made car stop to fall.
In the aforesaid elevator safety fender guard, the recoil spring between dash plate and the elevator inside is rectangular and distributes.Adopting this distribution mode can be that spring stress prevents that evenly discontinuity from dash plate bevelled situation takes place.
In the aforesaid elevator safety fender guard, the recoil spring between dash plate and elevator inside length from top to bottom increases gradually.Adopting this mode is for gradually that car is downward impulsive force eliminates, and prevents that car deceleration suddenly from causing injury to personnel in the elevator.
In the aforesaid elevator safety fender guard, the plate face of dash plate is provided with speed-reducing rubber piece A.It is in order to increase friction force that the speed-reducing rubber piece is set.
In the aforesaid elevator safety fender guard, said speed-reducing rubber piece A is shaped as triangle or semisphere.
In the aforesaid elevator safety fender guard, taper deceleration piece adopts the alloy material manufacturing to form.Taper deceleration piece adopts the reason of alloy material to be, alloy material is not yielding, and the taper deceleration piece that this material is set in the car bottom can prevent that car from deforming.
In the aforesaid elevator safety fender guard, the conical surface of taper deceleration piece is provided with speed-reducing rubber piece B.It is in order to increase friction force that the speed-reducing rubber piece is set.
In the aforesaid elevator safety fender guard, speed-reducing rubber piece B is shaped as triangle or semisphere.
Compared with prior art; Because the utility model is provided with dash plate in the bottom of elevator; And between dash plate and elevator, be provided with recoil spring; When taking place to weigh down terraced accident, the car downward impulsive force when contacting with dash plate that falls rapidly can be cushioned plate and weaken gradually, stops to fall up to car.Because anti-down recoil spring is longer than the recoil spring of top, dash plate increases to the resistance that car makes progress gradually, and car is steadily slowed down, and effectively protects personnel's in the car safety.Because the utility model does not need the auxiliary of electrical equipment therefore to need not power supply, even can normal operation when having a power failure yet.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model;
Fig. 2 is that speed-reducing rubber piece A and speed-reducing rubber piece B are hemispheric structural representation.
Being labeled as in the accompanying drawing: 1-dash plate, 2-recoil spring, 3-spring perch, 4-elevator, 5-car, 6-taper deceleration piece, 7-speed-reducing rubber piece A, 8-speed-reducing rubber piece B.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
The embodiment 1 of the utility model: as shown in Figure 1; A kind of elevator safety fender guard; Comprise dash plate 1, recoil spring 2 and spring perch 3, two symmetrical faces of the bottom of elevator 4 are provided with the dash plate 1 of symmetrical distribution, and the top of dash plate 1 is hinged through the inwall of hinge and elevator 4; Be provided with recoil spring 2 between the inwall of dash plate 1 and elevator 4, the two ends of recoil spring 2 are separately fixed on the spring perch of being located on dash plate 1 and the elevator 43; Be provided with car 5 in the elevator 4, the bottom of car 5 is provided with taper deceleration piece 6.Recoil spring 2 between dash plate 1 and elevator 4 inside is rectangular and distributes.Recoil spring 2 between dash plate 1 and elevator 4 inside length from top to bottom increases gradually.
The plate face of dash plate 1 is provided with speed-reducing rubber piece A7.Said speed-reducing rubber piece A7 is shaped as triangle.
The embodiment 2 of the utility model: as shown in Figure 1; A kind of elevator safety fender guard; Comprise dash plate 1, recoil spring 2 and spring perch 3, two symmetrical faces of the bottom of elevator 4 are provided with the dash plate 1 of symmetrical distribution, and the top of dash plate 1 is hinged through the inwall of hinge and elevator 4; Be provided with recoil spring 2 between the inwall of dash plate 1 and elevator 4, the two ends of recoil spring 2 are separately fixed on the spring perch of being located on dash plate 1 and the elevator 43; Be provided with car 5 in the elevator 4, the bottom of car 5 is provided with taper deceleration piece 6.Recoil spring 2 between dash plate 1 and elevator 4 inside is rectangular and distributes.Recoil spring 2 between dash plate 1 and elevator 4 inside length from top to bottom increases gradually.
As shown in Figure 2, the plate face of dash plate 1 is provided with speed-reducing rubber piece A7.Said speed-reducing rubber piece A7 is shaped as semisphere.Taper deceleration piece 6 adopts the alloy material manufacturing to form.
The conical surface of taper deceleration piece 6 is provided with speed-reducing rubber piece B8.Speed-reducing rubber piece B8 is shaped as semisphere.
The principle of work of the utility model: when fracture takes place the rope that elevator takes place; Car can descend rapidly; Taper deceleration piece 6 and dash plate 1 contact when the car bottom are provided with recoil spring 2 owing to change the back of plate 1 into, so dash plate 1 is understood the power that makes progress perpendicular to the conical surface to taper deceleration piece 6; This power gradually just the downward impulsive forces of car 5 weaken, stop to fall up to car 5.Because the awl wall of taper deceleration piece 6 is provided with speed-reducing rubber piece B8, the plate face of dash plate 1 is provided with speed-reducing rubber piece A7, therefore can increase the friction force between taper deceleration piece 6 and the dash plate 1, prevents the phenomenon that the two skids.
