Description
Technical field
This utility model is related to elevators field, and which is mainly concerned with a kind of elevator car top collapsible protective grill.
Background technology
Protective fence at top of elevator car is mounted in a kind of protection device of car top plate surrounding, mainly prevents car top maintainer
Generation fallen accident, requires according to national standard, and car top guard rail height is determined according to free distance between car top and well enclosure,
It is divided into 700mm and two kinds of height of 1100mm, but guard rail height will affects the overhead needed for elevator, build so as to increase
This is built up, the built building in part meets this situation can cause elevator meet national standard.
The content of the invention
It is an object of the invention to provide a kind of simple structure, it is easy to operate, safe and reliable car top collapsible protective grill, when this
When utility model car top collapsible protective grill is in off working state, elevator normally can run, when maintainer is needed into car top
During inspection operation elevator, it is necessary to fence assembly in activity is arranged to working condition, now elevator car roof repair function could just
Often use.
For achieving the above object, the present invention is adopted the following technical scheme that：
A kind of elevator car top collapsible protective grill, it is including the lower fence assembly for being fixed on car frame upper beam, solid by guide pipe
The upper fence assembly being scheduled on lower fence assembly, upper fence assembly are moved up and down along guide pipe,
Electric switch A is provided with the crossbeam of the lower fence assembly, in the vertical beam of the lower fence assembly, electricity is provided with
Air cock B,
Be provided with the upper fence assembly and hit bow support, it is described hit bow support in upper fence assembly moving process with electricity
Air cock B is contacted；
Elevator safety loop is connected to by electric switch C between the electric switch A and electric switch B.
In above-mentioned technical proposal, the upper fence assembly includes and guardrail extensible member connected vertically.
In above-mentioned technical proposal, the extensible member is arranged in guide pipe, and is moved up and down along guide pipe.
In above-mentioned technical proposal, the vertical beam corresponding position of lower fence assembly is provided with support on the fence assembly
Bar.
In above-mentioned technical proposal, hit bow support and be arranged on the support bar.
In above-mentioned technical proposal, the upper end of the support bar is provided with upper limit hole, and lower end is provided with lower limit hole.
In above-mentioned technical proposal, on lower fence assembly crossbeam, arrange limited with described upper and lower spacing hole correspondence position
Position axle.
Compared with prior art, the invention has the beneficial effects as follows：This programme raises guard rail from frame for movement, prevents dimension
Repair personnel and fallen accident occurs, meet；Pass through circuit system simultaneously
Reliable control, it is ensured that the car top collapsible protective grill must be arranged to working condition when personnel overhaul, prevent part repair and maintenance people
Member's responsibility is not enough, lazy the device not to be arranged to operating position.
Description of the drawings
Fig. 1 is this utility model electricity elevator car top collapsible protective grill off working state structural representation；
Fig. 2 is this utility model elevator car top collapsible protective grill working state structure schematic diagram；
Electrical schematic diagram when Fig. 3 is this utility model elevator car top collapsible protective grill working condition；
Electrical schematic diagram when Fig. 4 is this utility model elevator car top collapsible protective grill off working state；
Wherein:1 is lower fence assembly, and 2 is fence assembly in activity, and 3 switch A, and 4 is switch B, and 5 is to hit bow support, and 6 are
Upper limit hole, 7 is lower limit hole, and 8 are to maintain axle, and 9 is guide pipe.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
As shown in figure 1, off working state is sentenced for elevator extension guard rail, therefore its structure is known each other with original elevator, is stretched
Contracting guard rail is close to car top.
As Fig. 2, shown in, when collapsible protective grill sentences off working state, its lower fence assembly is fixed on sedan-chair frame upper beam,
In activity, fence assembly is fixed on lower fence assembly by guide pipe, and which can be up and down along guide pipe, and switch A is fixed on
On lower fence assembly entablature, the trigger switch when fence assembly moves to off-position in activity makes switch A safety contacts
Contact, switch C are switched on the Loop Contacts, connect elevator safety loop, and elevator normally runs；Switch B is fixed on lower guardrail
In component vertical beam, when in activity, fence assembly moves to operating position, switch A safety contacts disconnect, and cut off the safety return circuit,
It is also secured to hitting on fence assembly and bends support trigger switch B, contact switch B safety contacts, switch C is switched to this time
On the contact of road, connect the safety return circuit, be connected to switch D on the safety return circuit, switch E, switch F can normal work, realize
Overhauling elevator function.
When in activity, fence assembly moves to off-position, limit shaft insertion upper limit hole is prevented to switching A's
Damage, when the upper fence assembly of upper activity moves to operating position, by limit shaft insertion lower limit hole, make fence assembly in activity
It is maintained at operating position.
As shown in Figure 3, Figure 4, be switch electrical connection schematic diagram, select to cause which upper fence assembly sentences by switching
A kind of working condition.Therefore ensure that the car top collapsible protective grill must be arranged working condition when overhauling by personnel, prevent part
Repair and maintenance personnel responsibility is not enough, lazy that the device is arranged to operating position, so as to bring security risk.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
