Description
Technical field
The present invention relates to a kind of joggle trusses, and in particular to a kind of front-maintenance type splicing frame that electronic mode is run.
Background content
Concatenation unit is usually used by several display screens (liquid crystal-spliced screen/LED full-color screen) in existing large LED screen
It is spliced.Traditional liquid crystal-spliced unit is fixed as one, when the work such as being dismantled, replaced, repaired to display screen
It can only be operated from the back side of liquid crystal-spliced unit.When liquid crystal-spliced unit is mounted on the supporting bodies such as metope, with regard to nothing
Method is realized to be operated from the back side, and maintenance work just becomes very difficult.
In this case, come into vogue a kind of joggle truss that can be elastic in the market in recent years, on each concatenation unit
Preceding fixed seat for fixing display screen can make elastic movement, then, can be by preceding fixed seat when carrying out maintenance work
It is drawn into extended configuration forward, it is not necessary to be operated again from the back side.At present it is existing can elastic joggle truss use mostly
Hydraulic cylinder needs to stretch or push preceding fixed seat to realize stretching, extension or contraction manually.The weight of the preceding fixed seat of concatenation unit
Usually larger, this stretch mode causes high effort for, and when needing to carry out multiple display screens to be safeguarded, needs to splice one by one
Unit realizes that manual telescopic, working strength are very big.
Invention content
In view of the deficiencies of the prior art, the present invention is intended to provide safeguarding joggle truss before a kind of electric-controlled type, using electronic side
Fixed seat is flexible before formula carries out, and makees electric control to the elastic of all concatenation units using electric machine controller, significantly
It improves work efficiency, reduces working strength and workload.
To achieve the goals above, the present invention adopts the following technical scheme that：
Safeguard that joggle truss, including several concatenation units, each concatenation unit include preceding fixed seat, fix afterwards before electric-controlled type
Seat, is connected between the preceding fixed seat and rear fixed seat by telescoping shoring column；Each concatenation unit further includes electric linear
Dynamic device be set to it is described after fixed seat, the electric linear driving device include electric machine controller, motor, screw rod, telescopic rod with
And electric expansion support element, the motor are connected to the electric machine controller, one end of the screw rod is fixedly connected on the electricity
The output shaft of machine, the telescopic rod screw thread are socketed on the screw rod；One end of the electric expansion support element can relatively rotate
Ground is connected to one end of the telescopic rod, and the other end is then rotatably connected to the preceding fixed seat；All concatenation units
Electric machine controller be electrically connected in a general control system.
Further, the rear fixed seat is equipped with a lateral concave sliding slot, and the motor, screw rod and telescopic rod are set to
In the transverse direction concave sliding slot.
Further, the motor, screw rod and telescopic rod are mounted in a shell.
Further, the electric linear driving device further includes having a driven telescopic support, with the electric expansion
Support element rotatably constitutes X-type support element, and one end of the driven telescopic support is rotatably connected to institute
Preceding fixed seat is stated, the other end is then rotatably connected to the rear fixed seat.
Safeguard that the application method of joggle truss is before above-mentioned electric-controlled type：
Under normality, all concatenation units are in rounding state, at this point, the telescopic rod of electric linear driving device is in stretching, extension
State；
When needing the installation, maintenance on a certain concatenation unit or replacing display screen, spelled to corresponding by general control system
The electric machine controller of electric linear driving device in order member sends out the control signal of stretching, extension, the electricity of electric linear driving device
Machine is started to work under the control of electric machine controller；The motor output shaft drives screw rod to start to rotate；It is mutual with the screw rod
Telescopic rod one end of socket moves backward under the linkage with the screw rod, and the telescopic rod other end is in the band of one end of telescopic rod
The dynamic lower rotation made relative to preceding fixed seat, to the increasing presentation extended configuration of distance at the both ends of telescopic rod, and to preceding
Fixed seat generates forward thrust；At this point, telescope support is also extended movement under thrust, final preceding fixed seat is made forward
Then movement starts installation, maintenance or replaces display screen；
After the completion of installation, maintenance or replacement display screen, driven to the electric linear of corresponding mosaic screen by general control system
The electric machine controller of device sends out the control signal of contraction, under the control of electric machine controller, the motor output shaft of corresponding motor
It is rotated backward with screw rod, to which the telescopic rod drives one end of the electric expansion support element to move forward；Electric expansion
The other end of support element correspondingly rotates backward, and the smaller and smaller presentation of distance at the both ends of electric expansion support element is contraction-like
State generates pulling force backward to preceding fixed seat, and telescope support also makees contractile motion therewith, and the final preceding fixed seat moves back
It is dynamic, it is in rounding state again.
Further, when the electric expansion support element is extended or contractile motion, therewith constitute X-type support element from
Dynamic telescopic support, which is also driven, makees identical stretching, extension or contractile motion.
The beneficial effects of the present invention are：The preceding fixed seat that concatenation unit is controlled by the way of electronic is elastic, greatly
It is big to reduce working strength, and the unified of electric linear driving device for using electric machine controller to carry out each concatenation unit is controlled
System greatly improves the efficiency of control, reduces workload.
