Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
With becoming increasingly abundant for culture life, requirement of the people to stage effect in performing active is increasingly.In modernization stage
In design, to create a kind of lively three-dimensional performing effect, the mutual cooperation of a variety of stage machineries, such as lamp are generally required
Light, stage curtain etc. need to design multiple sunpenders thus to install these hanging objects on stage, and sunpender can be gone up and down, and put down
When be to be hung on the position that spectators above stage can't see, only arrangement stage when just lower to fix hanging object.At present
Sunpender lifting is mostly gone up and down using hoist engine pull-cord, and wherein design has wire casing on elevator machine cylinder, by cable takeup
In the wire casing of cylinder surface, but with the increase of take-up amount, hawser causes to hang there may be the risk for being disengaged from the groove rear cross winding
The security risks such as bar inclination, but most of hoist engines lack the warning device of hawser rounding state currently on the market.
Embodiment one: as shown in Fig. 1 to 2, a kind of only embodiment of one of them of the invention, stage goes up and down elevator
Machine cable takeup warning device, including elevator portion 1 and alarm portion 2, the elevator portion 1 is including reel 11 and for driving the volume
The driving machine 12 of 11 work of cylinder, the guiding that the alarm portion 2 includes support plate 21, connect by litter 22 with the support plate 21
Plate 23 and be set in the support plate 21 to 23 direction of guide plate be extended induction pieces 24, the induction pieces 24
It is electrically connected with the driving machine 12, is provided with spring 25 between the support plate 21 and the guide plate 23.
In the present invention, hawser is drawn in elevator portion 1, and hawser is pressed at reel 11 by the guide plate 23 in alarm portion 2
It is transmitted, once cable takeup, the guide plate 23 in alarm portion 2 can generate displacement, and alarm portion 2 sounds an alarm, and stop hawser and lead
Draw, avoids dangerous generation.
It is elevator portion 1 first, the elevator portion 1 includes reel 11 and the driving machine for driving the reel 11 to work
12, driving machine 12 is that reel 11 provides power.Hawser carries out coiling or traction in the outside of reel 11.
In practice, wire casing is both provided on reel 11, wire casing quantity is multiple, and a cable is only limited in a wire casing
Rope, hawser guide under the limit of wire casing.
Followed by the installation in alarm portion 2, the alarm portion 2 include support plate 21, by litter 22 and the support plate 21
The guide plate 23 of connection and be set in the support plate 21 to 23 direction of guide plate be extended induction pieces 24, institute
It states and is provided with spring 25 between support plate 21 and the guide plate 23.Support plate 21 is fixed plate, and guide plate 23 is movable plate, and
The guide plate 23 is set to the support plate 21 close to the side of the reel 11, and the support plate 21 and guide plate 23 pass through
Litter 22 connects, and guide plate 23 can be along the extending direction of litter 22, the free to slide and described support plate on litter 22
Spring 25 is provided between 21 and the guide plate 23, spring 25 provides elastic force and guide plate 23 is pressed to 11 direction of reel.
It is finally the generation of alarm, spring 25 provides elastic force and guide plate 23 is pressed to 11 direction of reel, transported in hawser
Cheng Zhong, the guide plate 23 press to reel 11, and the contact drawn on reel 11, once in hawser distraction procedure, hawser
It is detached from its original wire casing, then being inherently moved to other wire casings, is wound with the hawser in other wire casings, then winding
Wire casing in the diameter of hawser group become larger, and due to guide plate 23 and contact, then guide plate 23 can be under stress to branch
The displacement of 21 direction of fagging, guide plate 23 encounter the sense for being set to and being extended in the support plate 21 to 23 direction of guide plate
Part 24 is answered, induction pieces 24 are touched, and the induction pieces 24 are electrically connected with the driving machine 12, and induction pieces 24 send out inductive signal
It send to driving machine 12, driving machine 12 disconnects power supply, and reel 11 stops working, and avoids that the security risks such as sunpender inclination occur.
Once so cable takeup or reel 11 enter foreign matter, position occurs for the guide plate 23 that can all touch alarm portion 2
It moves, driving machine 12 stops working, highly-safe.
A kind of stage lift winch cable takeup warning device so of the invention is not only simple in structure, effectively solve due to
Hawser is disengaged from the groove the problem of rear mechanical system can not judge the rounding state of hawser in time and work on, and low in cost, practical
Property is strong.
Embodiment two, still as shown in Fig. 1 to 2, one of embodiment only of the invention, in order to enable the present invention is a kind of
The installation effect of stage lift winch cable takeup warning device is more preferable, and degree of stability is higher, also has in the present invention following
Design:
Firstly, the induction pieces 24 are magnetic switch.And the induction pieces 24 are electrically connected with alarm device.Magnetic switch incudes more
It is sensitive, be not necessarily required to that guide plate 23 touches induction pieces 24, once but guide plate 23 in 24 a certain range of induction pieces,
Induction pieces 24 can sense that the then power-off of driving machine 12 stops working, and security performance is higher, and the induction pieces 24 are electrically connected
There is alarm device, is sounded an alarm while the power-off of driving machine 12 stops working, staff is notified to carry out safety inspection.
In addition, the guide plate 23 is arranged in parallel with the reel 11, the length of the guide plate 23 is not less than the volume
The width of cylinder 11.23 length of guide plate is wide, then the hawser on reel 11 all can be oriented to and be incuded.
In addition, the angular range formed between the litter 22 and the guide plate 23 is 80 ° to 100 °.
The actually described litter 22 is to be arranged in a mutually vertical manner with the guide plate 23, then guide plate 23 can be perpendicular to cunning
Pole 22 is arranged, and during sliding along litter 22, guide plate 23 is more limited, more preferable to the guide effect of hawser.
And the litter 22 is connect by bearing 221 with the support plate 21.Litter 22 is fixedly attached to support plate
21, bearing 221 is more flexible, and 23 stability of guide plate is higher.
Certainly, the quantity of the litter 22 is at least one, and the quantity of the spring 25 is at least one.It is actually more
The identical spring 25 of a specification is uniformly set between the support plate 21 and guide plate 23, then the support plate 21 and leading
To plate 23, directly connection is more stable, and the elastic force that guide plate 23 is subject to is more balanced.
Finally, the support plate 21 is connected with the pedestal 211 for fixing the support plate 21.Guarantee that support plate 21 will not
Displacement, stability are good.
A kind of stage lift winch cable takeup warning device structure of the present invention is simple, effectively solves to be disengaged from the groove due to hawser
The problem of mechanical system can not judge the rounding state of hawser in time and work on afterwards, and it is low in cost, it is practical.
The present invention is not limited to above-mentioned specific embodiment, and the invention may be variously modified and varied.All foundations
Technical spirit of the invention should be included in the present invention to embodiment of above any modification, equivalent replacement, improvement and so on
Protection scope.
