Description
Technical field
The utility model belongs to elevator safety technical field, is specifically related to a kind of elevator protection device.
Background technology
In general, the Room door of elevator and the opening and closing of gate are controlled by a set of circuit being called the complexity of " vital circuit ", due to the Room door of elevator, gate and electrical motor, to be connected on " vital circuit " inner, when only having all Rooms door and gate all to close, the vital circuit that just formation one is closed, at this moment the electrical motor be connected in vital circuit just can work, and car just can move.Under normal circumstances, Room door and gate have one to open, and vital circuit will be caused to become open circuit, and electrical motor just can not work, and car also would not move.
Just because of vital circuit, the correct opening and closing of hoistway door and gate could be realized.But due to increasing of city high residential building quantity, the increase of elevator usage, elevator contingency quantity is increasing year by year, because fault causes unexpected main condition as follows:
1. natural fault.Due to during lift-mounting do not install or elevator period of service long, then can cause Room door or gate short circuit or be shorted, result is exactly, be not related to no matter this fault door closes, electronic function normally works, and this will cause hoistway door all likely to be opened at any time, produces inconsistent phenomenon.
2. human failure.Because maintainer has found fault, but in order to ensure that user normally uses as early as possible, so artificially by Room door or gate short circuit or open circuit.What is more, owing to can not check specifically which Room door or gate et out of order, so direct without hesitation, gate and all Rooms door are all shorting out, the consequence produced is exactly when elevator normally runs, gate and all Room doors are all likely opened at any time, cause dislocation accident, this will cause the injury to people's life.
Visible, all kinds of accidents that elevator door meets accident, its external manifestation is " inconsistent phenomenon " between lift car and layer door, and namely car is not to the floor of specifying, but the Room door of corresponding floor is opened; After this situation occurs, most people is in without prevention awareness state, comes into straight and occur that the elevator of inconsistent phenomenon causes fortuitous casualty.Even if find also late, the center of gravity of people turns forward, unexpected unavoidable.

Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model embodiment provides a kind of elevator protection device, as shown in Figure 1, this device comprises: two groups of protective cloths, four roll shafts, in described four roll shafts, the first roll shaft 2, second roll shaft 3 is separately positioned on the left and right sides of well headroom, and the 3rd roll shaft 5, the 4th roll shaft 4 are separately positioned on the left and right sides of shaft bottom; Upper one end of protective cloth 1 is connected with the top of car, the other end is connected with the upper end of clump weight 6 through the first roll shaft 2, second roll shaft 3, one end of lower protective cloth 11 is connected with the bottom of car, and the other end is connected with the lower end of clump weight 6 through the 3rd roll shaft 5, the 4th roll shaft 4.
The both sides of one end of described upper protective cloth 1 are connected with the top of car respectively by spring, and the both sides of the other end are connected respectively by the upper end of spring with clump weight 6, and described spring plays buffering and to regulate and the effect that makes protective cloth exceptionally straight.
The both sides of one end of described lower protective cloth 11 are connected with the bottom of car respectively by spring, and the both sides of the other end are connected respectively by the lower end of spring with clump weight 6, and described spring plays buffering and to regulate and the effect that makes protective cloth exceptionally straight.
Described upper protective cloth 1 and lower protective cloth 11 are provided with reflective layer near the side of Room door 10, described reflective layer, when there is dislocation and being unexpected, the light that reflective layer on protective cloth can reflect in stair reminds people, make user can have subconscious reaction and the stimulation having applied to external environment of stopping makes people create conditioned reflex for phosphor strip is reflective, when not through brain, make effector (locomotive organ of people) produce effect by reflex arc, make people stop advancing.
Described first roll shaft 2, second roll shaft 3 is connected with well headroom by spring.
Described 3rd roll shaft 5, the 4th roll shaft 4 are connected with shaft bottom by spring.
The two ends of described first roll shaft 2, second roll shaft 3 are connected with well headroom respectively by U-shaped connecting element, and the end at the two ends of described first roll shaft 2, second roll shaft 3 is separately positioned in U-shaped fixing arc groove; The two ends of described 3rd roll shaft 5, the 4th roll shaft 4 are connected with shaft bottom respectively by U-shaped connecting element, and the end at the two ends of described 3rd roll shaft 5, the 4th roll shaft 4 is separately positioned in U-shaped fixing arc groove; Like this, can guarantee that four roll shafts are only in the movement in vertical direction of spring, namely only make extensional motion, prevent the swing of four roll shafts, so ensure that protective cloth 1 and the distance between lower protective cloth 11 and Room door 10 tight.
Four springs on roll shaft, spring one end is connected to the axis of roll shaft, the other end is fixed on well headroom or bottom, when protective cloth pine (tightly), spring due to the change of stressed size, and then can be stretched (contracting), and then changes the locus of 4 roll shafts, and then increase distance needed for (minimizing) protective cloth, the state making protective cloth again reach an appropriateness to tighten.
Working process of the present utility model:
The wirerope 2 of the top connection of the car 9 of elevator is walked around electrical motor 3 and is connected with the upper end of clump weight 6, along with the driving of electrical motor 3, car 9 up-and-down movement of elevator, when car 9 upwards time, motion along with clump weight 6 drives upper protective cloth 1, and protective cloth 11 is upwards up and down, at this moment, if when there is inconsistent phenomenon in the upper floor of car 9 or lower floor, described upper protective cloth 1 or lower protective cloth 11 are owing to having blocked the space in face, the Room 10, force to stop user and enter hoistway, be strayed into hoistway damage so avoid user.
The above, be only preferred embodiment of the present utility model, is not intended to limit protection domain of the present utility model.
