A kind of liftable support for monitoring camera machine head
Technical field
The utility model belongs to the mounting technique field of watch-dog, relates to a kind of The Cloud Terrace support of CCTV camera, especially a kind of liftable support for monitoring camera machine head; Adopt this liftable support can realize the descending operation of monitoring camera machine head, to carry out maintenance protection to monitoring camera machine head.
Background technique
Along with the raising of intelligent substation application level, the video monitoring system for substation as one of " five is distant " is playing more and more important effect.How vidicon camera chooses suitable mounting point, how can monitor more scene to greatest extent, and how easy to maintenance etc. is the problem that security protection attendant is concerned about especially.
Monitoring camera machine head can carry out all-directional rotation to the camera lens in CCTV camera, to obtain the monitoring effect of more perspective; At present, monitoring camera machine head is widely used in field of intelligent monitoring.
In prior art, usually monitoring camera machine head is arranged at overhead higher position, the height of camera tilt head can reach 8 meters in some cases, this maintenance for vidicon camera is very inconvenient, also be difficult to safeguard even if attendant climbs insulating ladder extreme higher position, and likely cause falling from high altitude or touch the situation generations such as charging equipment by mistake.This is the deficiencies in the prior art part.
Model utility content
The purpose of this utility model is, for the defect that above-mentioned prior art exists, provides design a kind of liftable support for monitoring camera machine head, to solve the problems of the technologies described above.
For achieving the above object, the utility model provides following technological scheme:
A kind of liftable support for monitoring camera machine head, comprise column, described column has been disposed radially gap, leading screw is provided with in described column, described leading screw is combined with screw, described screw is fixed with cross bar, described cross bar is through described gap, make crossbar sections be positioned at the outside of column, the other end of described cross bar connects monitoring camera machine head.
Preferably, the top of described leading screw is provided with axle sleeve, and described axle sleeve is fixed on column; By arranging axle sleeve on column, leading screw being matched with axle sleeve, producing to avoid leading screw and rocking.
Preferably, the bottom of described leading screw is connected to the output shaft of drive motor; The bottom of leading screw is connected to the output shaft of drive motor, is driven forward and reverse rotation of leading screw by drive motor, thus screw is moved up and down along leading screw, then realize the lifting of monitoring camera machine head.
Preferably, the both sides of described gap are provided with elastic cord breaker; Elastic cord breaker is set by the both sides at gap, avoids cross bar to collide situation gap occurring fracture.
Preferably, described elastic cord breaker is rubber layer; Adopt rubber layer as elastic cord breaker, the effect of buffering can not only be played, and rubber layer is not easily aging, long service life.
Preferably, the thickness of described rubber layer is 2mm to 5mm; The thickness of rubber layer is set to 2mm to 5mm, effectively can either plays buffer function, and save rubber material, reduce costs.
Preferably, the thickness of described rubber layer is 3mm; The thickness of rubber layer is set to 3mm, effectively can either plays buffer function, and save rubber material, reduce costs.
The beneficial effects of the utility model are, by rotational lead screw, screw can be moved up and down, thus drive cross bar to move up and down along gap, finally make camera tilt head realize lifting function; In addition, the utility model design principle is reliable, and structure is simple, has application prospect widely.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.

Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is elaborated, and following examples are to explanation of the present utility model, and the utility model is not limited to following mode of execution.
Embodiment one:
As illustrated in fig. 1 and 2, a kind of liftable support for monitoring camera machine head that the utility model provides, comprise column 1, described column 1 has been disposed radially gap 3, is provided with leading screw 2 in described column 1, and described leading screw 2 is combined with screw 4, described screw 4 is fixed with cross bar 5, described cross bar 5, through described gap 3, makes cross bar 5 part be positioned at the outside of column 1, and the other end of described cross bar 5 connects monitoring camera machine head 6.
In the present embodiment, the top of described leading screw 2 is provided with axle sleeve 7, and described axle sleeve 7 is fixed on column 1; By arranging axle sleeve 7 on column 1, leading screw 2 being matched with axle sleeve 7, producing to avoid leading screw 2 and rocking.
In the present embodiment, the bottom of described leading screw 2 is connected to the output shaft of drive motor 8; The bottom of leading screw 2 is connected to the output shaft of drive motor 8, is driven forward and reverse rotation of leading screw 2 by drive motor 8, thus screw 4 is moved up and down along leading screw 2, then realize the lifting of monitoring camera machine head 6.
In the present embodiment, the both sides of described gap 3 are provided with elastic cord breaker; By arranging elastic cord breaker in the both sides of gap 3, cross bar 5 is avoided to collide situation gap 3 occurring fracture.
In the present embodiment, described elastic cord breaker is rubber layer; Adopt rubber layer as elastic cord breaker, the effect of buffering can not only be played, and rubber layer is not easily aging, long service life.
In the present embodiment, the thickness of described rubber layer is 2mm; The thickness of rubber layer is set to 2mm, effectively can either plays buffer function, and save rubber material, reduce costs.
Embodiment two:
The difference of the present embodiment and embodiment one is: in the present embodiment, and the thickness of described rubber layer is 3mm; The thickness of rubber layer is set to 3mm, effectively can either plays buffer function, and save rubber material, reduce costs.
Embodiment three:
The difference of the present embodiment and embodiment one is: in the present embodiment, and the thickness of described rubber layer is 5mm; The thickness of rubber layer is set to 5mm, effectively can either plays buffer function, and save rubber material, reduce costs.
Preferred implementation of the present utility model is only above; but the utility model is not limited thereto; any those skilled in the art can think there is no creationary change; and do not departing from the some improvements and modifications done under the utility model principle prerequisite, all should drop in protection domain of the present utility model.
