Description
Technical field
The utility model relates to a kind of latching device, particularly a kind of elevator hand latching device using during for elevator reparing.
Background technology
In order to ensure lift running safety, staff need to regularly safeguard elevator and overhaul as maintenance platform by car.When safeguarding and overhaul, in order to guarantee staff's safety, first need car to be stably fixed on guide rail.The general elevator hand latching device that adopts is fixed on car on guide rail now.Existing elevator hand latching device is generally that the locating plate by the latch insertion being fixed on beam processed is fixed on guide rail is guaranteed the stable of car, but because latch plate and handle switch cumbersomely between off working state and mode of operation, use inconvenient.And, there is certain potential safety hazard in the position between manual shift switch contact and groove always when disconnecting and switching on power.Therefore there is inconvenient and the undesirable problem of safety performance used in existing elevator hand latching device.
Utility model content
The purpose of this utility model is, a kind of elevator hand latching device using during for elevator reparing is provided.The utility model has improved elevator hand latching device, has advantages of easy to use high with safety performance.
The technical solution of the utility model: a kind of elevator hand latching device, comprise lock bracket, lock bracket is connected to car upper beam lower end; Car upper beam side connection guide rail, guide rail rear end is connected with locating plate; On lock bracket, be provided with handle and lock shaft; Lock shaft front end is provided with groove, and groove lower end is provided with switch contact and switch seat; Lock shaft rear end is provided with positioning plate, and positioning plate is connected with lock bracket by spring.
In aforesaid elevator hand latching device, on described lock shaft, have fixed orifice, lock shaft is positioned at the top of handle, and handle connects lock shaft by fixed orifice.
In aforesaid elevator hand latching device, on described locating plate, have knock hole, lock shaft is by knock hole connected positioning plate.
Compared with prior art, the utility model is provided with groove, fixed orifice, positioning plate and spring on lock shaft.During locking, only lock shaft need to be moved forward, then will on handle, move just fixedly car and disconnect elevator power supply.After a bit of distance that only need to again lock shaft be moved forward during reset, unclamp, just lock shaft can be resetted and switch on power.Therefore the utlity model has the easy to use and high advantage of safety performance.
Accompanying drawing explanation
Fig. 1 is reset mode structural representation of the present utility model;
Fig. 2 is locking state structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-lock bracket, 2-car upper beam, 3-guide rail, 4-locating plate, 5-handle, 6-lock shaft, 7-groove, 8-switch contact, 9-switch seat, 10-positioning plate, 11-spring, 12-fixed orifice, 13-knock hole.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of elevator hand latching device forms as shown in Figure 1, 2, comprises lock bracket 1, and lock bracket 1 is connected to car upper beam 2 lower ends; Car upper beam 2 side connection guide rails 3, guide rail 3 rear ends are connected with locating plate 4; On lock bracket 1, be provided with handle 5 and lock shaft 6; Lock shaft 6 front ends are provided with groove 7, and groove 7 lower ends are provided with switch contact 8 and switch seat 9; Lock shaft 6 rear ends are provided with positioning plate 10, and positioning plate 10 is connected with lock bracket 1 by spring 11.
On described lock shaft 6, have fixed orifice 12, lock shaft 6 is positioned at the top of handle 5, and handle 5 connects lock shaft 6 by fixed orifice 12.On described locating plate 4, have knock hole 13, lock shaft 6 is by knock hole 13 connected positioning plates 4.
During locking, install from reset mode and be switched to locking state.As shown in Figure 1, manually promote forward in the direction of arrows lock shaft 6, make in the knock hole 13 in lock shaft 6 insertion locatings plate 4.Now, the fixed orifice 12 on lock shaft 6 is positioned at handle 5 tops, therefore can manually handle 5 be advanced in fixed orifice 12.Here to note making part that on handle 5, diameter is larger higher than lock shaft 6 tops.Then unclamp lock shaft 6, owing to giving 10 1 restoring forces of positioning plate after spring 11 compressions, make positioning plate 10 drive lock shaft 6 to move backward.In lock shaft 6, in the interior side contacts handle 5 of fixed orifice 12 during less a part of of diameter, lock shaft 6 is fixed, and the part that in handle 5, diameter is larger is stuck on lock shaft 6.Under this state, groove 7 reaches, move down switch contact 8.Switch contact 8 is closed elevator power supply by switch seat 9.Lock shaft 6 and handle 5 are fixing, and lock shaft 6 and adapter plate 4 are fixing, complete the locking of elevator.
During reset, install from locking state and be switched to reset mode.As shown in Figure 2, manually promote forward in the direction of arrows lock shaft 6, fixed orifice 12 moves forward, and handle 4 comes off from lock shaft 6, then unclamps lock shaft 6.Under the elastic force effect of spring 11, positioning plate 10 drives lock shaft 6 to move backward, and lock shaft 6 is separated with locating plate 4.When positioning plate 10 touches lock bracket 1 lower end, positioning plate 10 stops mobile.Can guarantee that like this groove 7 just moves to the top of switch contact 8.Now, on switch contact 8, move, elevator power connection, completes the reset of elevator.
