Description
Technical field
The utility model relates to the elevator field, relates in particular to a kind of elevator maintenance safety device.
Background technology
Elevator need overhaul and safeguard in daily use.General conventional elevator is when carrying out car top maintenance parts; The braking of lift car relies on the brake gear of driving host that main frame traction sheave band-type brake is checked; And the friction force through traction steel-cable and traction sheave, thereby lift car is fixed in certain position of elevator hoistways.For machine-roomless lift; Because its driving host, elevator control cabinet all are installed on the top of elevator hoistways; When needs overhauled the main engine, change main frame or change the elevator traction steel rope, the brake gear of driving host just can't play a role, thereby can't lift car be fixed in certain position of elevator hoistways; Need this moment to use the lift car safety tongs to check on cage guide, utilize tackles that lift car is sling simultaneously.But because the elevator hoistways inner space is limited, tackles is difficult to fix, and workmen's complicated operation, and is dangerous higher, wastes time and energy.
The utility model content
The applicant provides a kind of elevator maintenance safety device simple in structure, easy for installation to the shortcoming that exists in the above-mentioned maintenance process, has advantages such as simple to operate, safety height.
The technical scheme that the utility model adopted is following:
A kind of elevator maintenance safety device; Comprise a shape base plate; Base plate is affixed with a side that is fixed on elevator car roof upper beam plate body, and the two ends of base plate stretch out and form front side plate and rear quarter panel, on front side plate and rear quarter panel, have the corresponding mounting hole in position; In the mounting hole of front side plate and rear quarter panel, install first axle sleeve and second axle sleeve respectively, the locking bar through-going device is in first axle sleeve and second axle sleeve; Returning apparatus spring, set pin and handle on locking bar;
Side at the upper beam plate body is also installed the travel switch fixed mount, and travel switch fixed mount and base plate are positioned at the same side of upper beam plate body, on the travel switch fixed mount, travel switch is installed, and travel switch is resisted against an end of locking bar.
It is further characterized in that:
Have the opening that matches with the set pin size on said second axle sleeve;
Also have " U " shape opening on the said base plate.
The beneficial effect of the utility model is following:
During upkeep operation, only need locking bar be inserted in the waist shape lockhole of guide rail fixed mount, make lift car be in stationary state with respect to guide rail, it is easy to operate; Removed the contact relation between locking bar and travel switch with the insertion of hour locking lever, travel switch sends signal, controls electric cabinet cut off, thereby the lift car outage can't be moved, and has improved the safety of operating personal when upkeep operation greatly.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
To shown in Figure 2, the utility model comprises a base plate 402 like Fig. 1, and base plate 402 is affixed with a side that is fixed on lift car 1 top upper beam plate body 5.The two ends of base plate 402 stretch out and form front side plate 408 and rear quarter panel 409; On front side plate 408 and rear quarter panel 409, have the corresponding mounting hole in position; Install first axle sleeve 401 and second axle sleeve 405 respectively in the mounting hole of front side plate 408 and rear quarter panel 409, locking bar 403 through-going devices are in first axle sleeve 401 and second axle sleeve 405; Go back mounting spring 404, set pin 406 and handle 407 on the locking bar 403.Have the opening (opening is not shown) that matches with set pin 406 sizes on second axle sleeve 405.As shown in Figure 1, on base plate 402, also have " U " shape opening.
As shown in Figure 7, in a side of upper beam plate body 5 travel switch fixed mount 9 is installed also, travel switch fixed mount 9 and base plate 402 are positioned at the same side of upper beam plate body 5, and travel switch 8 is installed on travel switch fixed mount 9, and travel switch 8 is resisted against an end of locking bar 403.As shown in Figure 8, travel switch 8 contacts with locking bar 403, and travel switch 8 links to each other with the electric cabinet of control (switching line with control electric cabinet not shown in the drawings) through switching line, guarantees that lift car is in running state.
Like Fig. 6, Fig. 7 and shown in Figure 8; At the top of lift car 1 upper beam plate body 5 is installed, to shown in Figure 5, leads boots fixed mount 501 in the installation of the top of upper beam plate body 5 like Fig. 3; Like Fig. 6, shown in Figure 7; Lead boots assembly 3 leading on the boots fixed mount 501 to install, lead boots assembly 3 and guide rail 2 sliding block joints, lift car can be slided along guide rail 2.Guide rail 2 is fixed on the brace panel 6 through guide rail clip 201 and fastener; As shown in Figure 9, on brace panel 6, go back mounting guide rail lock fixed mount 7, on guide rail lock fixed mount 7, have waist shape lockhole 701.
In the elevator maintenance process; Move in the waist shape lockhole 701 on locking bar 403 to the guide rail fixed mount 7; Turning handle 408; Set pin 406 on locking bar 403 turns in the opening of second axle sleeve 405, and this moment, lift car was fixed, and led boots assembly 3 and can't drive lift car 1 and slide along guide rail 2.And the mobile contact relation of having removed between locking bar 403 and the travel switch 8 of locking bar 403; Travel switch 8 sends signal; Control electric cabinet cut off, thereby make lift car 1 be in off-position and can't move, improved the safety of operating personal when upkeep operation greatly.
Like Fig. 6, shown in Figure 7, the upper beam plate body 5 at lift car 1 top is provided with two cover elevator maintenance safety devices, could realize the stationary state of lift car.
Above-mentionedly lead its structure of boots assembly and principle of work all adopts existing known technology.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the basic structure of the utility model, the utility model can be done any type of modification.
