Abstract
The invention discloses an elevator underbeam dropping control device, which comprises a car and a car guide rail, and is characterized in that both the car and the car guide rail are provided with pin holes, and the car is provided with a pin passing through the pin holes. For the elevator underbeam dropping control device disclosed by the invention, through arranging a mechanical stopping device, i.e. the pin, the car can be ensured not to drop, meanwhile, with an auxiliary limit switch, the safety of the working region can be further ensured. The elevator underbeam dropping control device disclosed by the invention has the advantages of simple structure, safety and reliability in use, and the like.
Description
Technical field
The invention belongs to elevator and make the field, relate in particular to a kind of underbeam anti-drop device of elevator.
Background technology
The car of elevator is vertically mounted in the elevator, during maintenance, usually lift car is parked in elevator bottom, is got in the elevator below the car by the workman then and overhauls, and this moment, car rested on maintenance worker's the crown.Though the electric locking device of car is arranged, car is fixed, cause the car tenesmus to have an accident because of electrical failure or human operational error and happen occasionally.Lift car is locked when how to guarantee to overhaul, do not drop at electric et out of order or when receiving wrong operating instruction yet, and be the problem that the present invention will solve.
Summary of the invention
The invention provides a kind of solution of the above problems, elevator underbeam anti-drop device a kind of simple in structure, safe and reliable is provided.
Technical scheme of the present invention provides a kind of elevator underbeam anti-drop device, and it comprises car and car guide rail, it is characterized in that: said car is provided with said car is fixed on the bolt device on the said car guide rail.
Preferably, said bolt device comprises pin-and-hole that is arranged on said car and the car guide rail and the latch that can pass two said pin-and-holes.
Preferably, said car guide rail is provided with limit switch, and said car is provided with the bow that hits that triggers said limit switch.
Preferably, it also comprises the inspection switch that is used to start and close said limit switch.
Preferably, also be provided with the safety protection switch that is used to cut off said car up-downgoing instruction on the said car.
A kind of elevator underbeam anti-drop device of the present invention is through being provided with a mechanical stop arrangement, and promptly latch can guarantee that car can not drop, and auxiliary simultaneously limit switch is further guaranteed the safety of work area.A kind of elevator underbeam anti-drop device of the present invention has advantages such as simple in structure, safe and reliable.
Description of drawings
Fig. 1 is the structural representation of a kind of elevator underbeam anti-drop device of the present invention.
The specific embodiment
Following specific embodiments of the invention is described in further detail.
As shown in Figure 1, a kind of elevator underbeam anti-drop device of the present invention comprises car 10 and car guide rail 12.Be provided with pin-and-hole (not shown) on car 10 and the car guide rail 12, car 10 is provided with the latch 14 that can pass two pin-and-holes.Car guide rail 12 is provided with limit switch 16, and car 10 is provided with hitting of triggering limit switch 16 and bends 18.It also comprises the inspection switch (not shown) that is used to start and close limit switch 16 and is arranged on the safety protection switch 20 (UKS switch) that also is useful on cut-out car 10 up-downgoings instruction on the car 10.
When elevator main breaks down, manually the inspection switch of (not shown) in the control housing to be opened, this moment, limit switch 16 energisings were effective, and when elevator ran to limit switch 16, the elevator downlink command lost efficacy, and elevator can't be descending; Manually with latch 14 penetrate adapter plate at hoistway this moment, and fixedly the safety protection switch 20 on the adapter plate breaks off car 10 time, and elevator can't move (on give an order all lost efficacy), can overhaul at this moment.
After maintenance finishes, manually latch 14 is resetted, safety protection switch 20 is connected elevator can be up, manually inspection switch in the control housing closed, and elevator can normally move.
A kind of elevator underbeam anti-drop device of the present invention can play duplicate protection electric and machinery, and actv. prevents the maintenance safety hidden danger that electrical failure is brought.
Above embodiment is merely the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
