Abstract
The utility model discloses an elevator underbeam dropping-preventing device. The elevator underbeam dropping-preventing device comprises an elevator cage and an elevator cage guiding rail, and is characterized in that pin holes are formed in the elevator cage and the elevator cage guiding rail; and a pin capable of penetrating the two pin holes is arranged on the elevator cage. The elevator underbeam dropping-preventing device can prevent the elevator cage from dropping down by arranging a mechanical stopping device, namely the pin; an auxiliary limiting switch can further ensure the safety of a working area; and the elevator underbeam dropping-preventing device has the advantages of simple structure, safety, reliability and the like.
Description
Technical field
The utility model belongs to elevator and makes the field, relates 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 utility model will solve.
Summary of the invention
The utility model provides a kind of solution of the above problems, and elevator underbeam anti-drop device a kind of simple in structure, safe and reliable is provided.
The technical scheme of the utility model 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 utility model 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 utility model 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 utility model.
The specific embodiment
The specific embodiment in the face of the utility model is described in further detail down.
As shown in Figure 1, a kind of elevator underbeam anti-drop device of the utility model 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 utility model 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 utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
