Abstract
The utility model relates to the field of elevators, in particular to an elevator guide rail. The self-protecting elevator guide rail in case of outage comprises a guide rail body and a safety assembly. An accommodating groove is arranged on the guide rail body, the safety assembly is arranged in the accommodating groove, the safety assembly comprises a dragging electromagnet, a compression spring and a stopping iron, the dragging electromagnet is fixedly arranged in the accommodating groove, and the electromagnet and the stopping iron are connected through the compression spring. The stopping iron has a compression position in power-up state and a stopping position in outage state. When the stopping iron is arranged at the compression position, a guiding face of the guide rail and an outer surface of the stopping iron are in the same plane. Compared with other safety mechanisms required to be overhauled at regular time, the safety and reliability of the self-protecting elevator guide rail are high. The safety of the safety mechanism can not be reduced even if the safety mechanism is not overhauled, once the dragging electromagnet is damaged and fails, the stopping iron can be protruded naturally and found out by working staff, and safety operation of the elector is effectively guaranteed.
Description
Technical field
The utility model relates to the elevator field, relates in particular to a kind of cage guide.
Background technology
Elevator is a kind of vertical conveyor take electrical motor as power, and case shape gondola is housed, and is used for tier building and takes advantage of people or carrying goods.It has a car, operates in the vertical or leaning angle of at least two row less than between 15 ° the rigid guideway.Car size and version are convenient to passenger's discrepancy or loading and unloading goods.
Modem elevator mainly is comprised of towing machine, guide rail, counterweight, safety device, signal manipulation system, car and Room door etc.These parts are installed in respectively in the hoistway and machine room of building.Usually adopt Wire Friction Driving, steel rope is walked around traction sheave, and two ends connect respectively car and counterbalanced weight, and the direct motor drive traction sheave makes the car lifting.That elevator requires is safe and reliable, transport efficiency is high, leveling accuracy and ride comfort etc.Wherein, safe and reliable is elevator performance of paramount importance; existing safety device comprises such as velocity limiter, energy disperser etc.; mostly be greatly the passive car that acts on; velocity limiter, energy disperser etc. can to a certain degree reduce the car falling speed when car stall is fallen; and shock absorbing power realizes protection occupant's purpose.
But existing these safety devices still can't thoroughly solve safety problem, so Frequent Accidents, the Partial security device relies on the electric power running, both can't work once go out the first loss of power accident, another part safety apparatus structure complexity and poor reliability be not once not timely the maintenance is easy to inefficacy.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of automatic cut-off protection and protects cage guide; this guide rail is provided with the iron block that stops by magnet control at guide rail; guarantee to stop that in when outage iron block can auto-extending, the locking elevator is avoided elevator generation falling accident.
The utility model is achieved in that a kind of automatic cut-off protection protects cage guide, comprise guide rail and security component, described guide rail is provided with accommodating groove, described security component is arranged in the accommodating groove, security component comprises towed electromagnet, Compress Spring and stops iron block, described towed electromagnet is fixedly mounted in the accommodating groove, and described electromagnet links to each other by Compress Spring with stopping between the iron block; The described iron block that stops has the position that stops of the compressed-bit of "on" position and off-position, when stopping that iron block is in compressed-bit, the spigot surface of guide rail with stop that the outside face of iron block is in same plane.
Described security component has several, and some security components equidistantly vertically are arranged on the guide rail.
The described iron block that stops is taper, stops the inner surface area of iron block less than outside face, and described accommodating groove matches with stopping iron block.
The described iron block that stops is wedge shape, stops that the upper surface of iron block is the plane, stops that the lower surface area of iron block is less than the upper surface.
The utility model automatic cut-off protection protects and is provided with the towed electromagnet of a row on the guide rail of cage guide, and towed electromagnet absorption stops in the iron block retraction guide rail when energising, can not have influence on elevator cab movement; Once cut off the power supply, stop iron block meeting auto-extending under the thrust of Compress Spring, stop that car falls; Need to regularly to overhaul its safe reliability just the opposite with other safety gears, even not overhauling also, safety mechanism can not reduce safety, because once towed electromagnet damage to lose efficacy, stop that iron block can give prominence to naturally, found by the staff, effectively guaranteed the safe operation of elevator.
Description of drawings
Fig. 1 is that the utility model automatic cut-off protection protects the cage guide structural representation;
Fig. 2 stops the iron block structural representation among the embodiment 1;
Fig. 3 stops the iron block structural representation among the embodiment 2.
Among the figure: 1 guide rail, 2 towed electromagnet, 3 accommodating grooves, 4 Compress Springs, 5 stop iron block, 6 hoistways.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, a kind of automatic cut-off protection protects cage guide, comprise guide rail 1 and security component, guide rail 1 is arranged in the hoistway 6, described guide rail 1 is provided with accommodating groove 3, and described security component is arranged in the accommodating groove 3, and security component comprises towed electromagnet 2, Compress Spring 4 and stops iron block 5, described towed electromagnet 2 is fixedly mounted in the accommodating groove 3, and described electromagnet 2 links to each other by Compress Spring 4 with stopping between the iron block 5; The described iron block 5 that stops has the position that stops of the compressed-bit of "on" position and off-position, when stopping that iron block 5 is in compressed-bit, the spigot surface of guide rail 1 with stop that the outside face of iron block 5 is in same plane.
In the utility model, described security component has several, and some security components equidistantly vertically are arranged on the guide rail 1.
In addition, in the present embodiment, as shown in Figure 2, have influence on the location that stops iron block 5 for the up-and-down movement that prevents lift car, the described iron block 5 that stops is taper, stops the inner surface area of iron block 5 less than outside face, and described accommodating groove 3 matches with stopping iron block 5.
Embodiment 2
As shown in Figure 3; a kind of automatic cut-off protection protects cage guide; the difference of embodiment 2 and embodiment 1 is; the described iron block 5 that stops is wedge shape; the upper surface that stops iron block 5 is the plane, stops the lower surface area of iron block 5 less than the upper surface, and the part moment that stops when iron block 5 is stressed in the upper surface of wedge shape can change into perpendicular in the guide rail 1; improve the resistance to shear that stops iron block 5, can more be conducive to guarantee elevator safety.
