Description
Technical field
The utility model is related to technical field of elevator manufacturing, especially a kind of hoistway door sill of easy access.
Background technology
Hoistway door generally all carries function of self closing as the safeguard protection barrier of elevator hoistways, but in the day of elevator
During normal maintaining, repair and maintenance personnel need frequently to come in and go out lift car or reach elevator car top, it is necessary to hoistway door
It is maintained at door opening state.Because hall door carries function of self closing, to ensure that hoistway door maintenance door opening state needs to apply hall door
External force prevents the self-closing of hall door.Existing lading door dill is that guide effect is played during switch gate, in elevator maintenance
Servicing operations are, it is necessary to when hall door is maintained at door opening state, maintenance personal is generally stopped using weight or prevented using specific purpose tool
Hall door is closed, and specifically, typically blocks weight on hoistway door sill to prevent hall door from closing, or in lading door dill
In groove beyond the Great Wall batten or other instruments preventing to close the door.Stop unreliable using weight, there is potential safety hazard, influence sill is strong
Degree, elevator faults are easily caused after elevator resumes operation；Using specific purpose tool high cost, and repair and maintenance personnel are needed to carry with, easily
Lose, not enough facilitate.
In order to solve the above problems, Chinese publication CN201545583U discloses a kind of hoistway door, in sill sheet
The stop member for making door leaf maintain a normally open state is provided with vivo, and stop member can be to be arranged on the lifting choosing of sill body interior energy
The gripping mechanism selected, gripping mechanism includes upper T forming head and bottom T-shaped head, upper T forming head and bottom T-shaped head connection composition I types
Structure.The program can remain on easily hoistway door, it is ensured that the job safety of maintenance personal, but, the clamping
Device can produce vibrations, abnormal sound, poor reliability when elevator normally runs because of elevator operation；Perforate reduces sill on sill
Structural strength, gripping mechanism work when sill can be caused to deform with the mutual operation of sill.
Utility model content
The utility model provides a kind of hoistway door sill of easy access, is not easy to for solving existing hoistway door
The problem of maintenance.
In order to solve the above problems, the utility model provides a kind of hoistway door sill of easy access, including sill sheet
Body, offers two location holes on the sill body, two location holes are on hoistway door switch gate direction along described
The center line of sill body is symmetrical, door opening width of the distance between the two described location holes equal to hoistway door；It is described
Staking is fixed with location nut in location hole, and the screw for preventing hoistway door from closing is provided with the location nut.
The hoistway door sill of the easy access that the utility model is provided also has following technical characteristic：
Further, the upper surface of the location nut is provided with counterbore, and the screw is hexagon socket countersunk flat cap head screw, the spiral shell
Following closely can be placed in the counterbore of the location nut with the end of location nut cooperation and the screw.
Further, the location hole is slotted hole.
Further, the connecting bolt for being fixedly linked with elevator hoistways is additionally provided with the sill body.
The utility model has the advantages that：Location hole is set by sill body, the staking in location hole
Location nut is installed, screw is screwed into during maintenance lift in location nut, screw can prevent hoistway door from closing；After maintenance terminates
Screw is back-outed can release locking to hoistway door；The staking stationary positioned nut in location hole, thus can strengthen sill sheet
The structural strength of body, can also prevent screw from causing sill body distortion in hoistway door closing process is stopped, security performance is high；
Using screw as the stop member that hoistway door is closed is stopped, convenient material drawing is not required to buy specific purpose tool, low cost；The knot
Structure such as fixes, is threadedly coupled at the immovable fitting using staking, will not produce vibrations, abnormal sound, good reliability because of elevator operation.
Brief description of the drawings
Fig. 1 is the top view of the hoistway door sill of the easy access of the utility model embodiment；
Fig. 2 is the left view of the hoistway door sill in Fig. 1；
Fig. 3 is the use state schematic diagram of the hoistway door sill in Fig. 1；
Fig. 4 is another structural representation of the hoistway door sill of the easy access of the utility model embodiment.
Specific embodiment
Describe the utility model in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that not rushing
In the case of prominent, the feature in embodiment and embodiment in the utility model can be mutually combined.
In one embodiment of the hoistway door sill of easy access of the present utility model as shown in Figures 1 to 4, this is just
Include sill body 10 in the hoistway door sill of maintenance, two location holes 11, two location holes are offered on sill body 10
11 is symmetrical along the center line of sill body 10 on the switch gate direction of hoistway door 20, the distance between two location holes 11
Equal to the door opening width of hoistway door 20；11 stakings are fixed with location nut 30, location nut 30 and are provided with use in location hole
In the screw 40 for preventing hoistway door 20 from closing.The hoistway door sill of the easy access of the embodiment, by sill body
Upper setting location hole, location nut is installed in staking in location hole, is screwed into screw during maintenance lift in location nut, and screw can
Hoistway door is prevented to close；Repair screw is back-outed after the terminating locking that can be released to hoistway door；Staking is consolidated in location hole
Determine location nut, thus can strengthen the structural strength of sill body, can also prevent screw stop hoistway door closing process in
Sill body distortion is caused, security performance is high；The stop member closed as stop hoistway door using screw, convenient material drawing,
It is not required to buy specific purpose tool, low cost；The structure such as fixes, is threadedly coupled at the immovable fitting using staking, will not be run because of elevator
Produce vibrations, abnormal sound, good reliability.
In the above-described embodiments, the hoistway door sill of easy access also has following technical characteristic：Location nut 30
Upper surface is provided with counterbore, and screw 40 is hexagon socket countersunk flat cap head screw, and screw 40 coordinates with location nut 30 and the end of screw 40 can
It is placed in the counterbore of location nut 30；Thus screw 40 can be screwed into location nut at the end of maintenance, screw is moved downward,
So that the upper surface of the end of screw is screwed into location nut 30, it is now screw concealed not influence hoistway door in location nut
Close；When needing repairing, screw is turned, screw upwards expose location nut to prevent hoistway door from closing by motion.The elevator hall
Gate sill process is simple, operates with simplicity, both saves human cost, maintains easily again and uses.
In the above-described embodiments, location hole 11 can be installation of the slotted hole in order to location nut；On sill body 10
The connecting bolt 12 for being fixedly linked with elevator hoistways is additionally provided with, is thus easy to sill body in elevator hoistways or floor hall door
Installed on floor.Further, in above-described embodiment, also can the direct thread mill drilling on sill body, screw is twisted
Enter screw hole to prevent hoistway door from closing.
Finally it should be noted that：Above example is only used to illustrate the technical solution of the utility model, rather than its limitations；
Although being described in detail to the utility model with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, the essence of appropriate technical solution is departed from each embodiment technology of the utility model
The spirit and scope of scheme.
