Description
Technical field
The present invention relates to automation field, refer to especially a kind of tower crane ground control cabinet.
Background technology
Tower crane is a kind of weight-lifting equipment the most frequently used on building ground, has another name called tower crane, with a section spreading, is used for hanging the raw MAT'L of the constructions such as working reinforcing bar, wood are stupefied, cement concrete, steel pipe.
By having or not traveling gear can be divided into portable tower tower crane and fixed type tower crane.
Portable tower tower crane can be divided into again four kinds of rail mounteds, rubber-tyred, truck mounted, crawler type according to the difference of running gear.The tower tower crane tower body of rail mounted is fixed on walking underframe, can on ad hoc track, move, and good stability, can walk by on-load, and work efficiency is high, thereby is widely used in building installation engineering.The tower tower crane rail-free of rubber-tyred, truck mounted and crawler type device, conveniently moving, but can not on-load walking, less stable.
The tower tower crane of fixed type is according to the difference of installation position, is divided into again and adheres to two kinds of jack up and inner climbing types, adheres to from rising tower tower crane and can raise with building, be applicable to skyscraper, the horizontal load being transmitted by tower crane is only born in building structure, convenient attachment, but it is many to take structural steel; Inner climbing crane tower, at interior of building (elevator, stair case), climbs by a set of bracket and elevator system, and jacking is more loaded down with trivial details, but it is few to take structural steel, does not need installing basis, and all deadweight and load are born by building.
No matter be movable tower crane or fixed type tower crane, all need operating personal voluntarily or arrive by elevator between the control at top and operate, stand the working environment of high temperature and heating summer or low temperature severe cold, and tower crane is higher, danger coefficient is also higher, and tower crane accident also happens occasionally, therefore, how realizing the Long-distance Control of high-order tower crane, is current problem demanding prompt solution.
Summary of the invention
The present invention proposes a kind of tower crane ground control cabinet, has realized the Long-distance Control to high-order tower crane.
Technical scheme of the present invention is achieved in that
A kind of tower crane ground control cabinet, comprising:
Handle hand lever, with actual hand lever 1:1 Proportionality design;
Travel switch, is arranged in the action slot of each manipulation hand lever the position of inductive control hand lever, output switching signal;
Pressure sensor, is connected with described manipulation hand lever, and the pressure signal of handling hand lever is converted to electric signal;
Described travel switch is complete corresponding setting with pressure sensor;
Electronic switch, its control end is connected to described travel switch, and its passage two ends are connected respectively to described pressure sensor and AD converter;
Dsp processor, is connected to described AD converter, and pressure signal is encoded;
The first gateway, is transferred to pressure code signal the control box of a tower crane high position;
Described control box comprises the second gateway, receives described pressure code signal;
PLC controller, according to startup and the rotating speed of respective electrical motivation in described pressure signal control motor unit.
Alternatively, described travel switch is photoelectricity correlation switch.
Alternatively, described dsp processor is TMS320F2812 dsp processor.
The invention has the beneficial effects as follows:
Build on the ground the simulation operations platform identical with actual platform, send instruction by gateway to the control box at tower crane top, control tower crane action, realize tower crane Long-distance Control.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the control block diagram of tower crane ground control cabinet of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of tower crane ground control cabinet of the present invention, comprising: handle hand lever 50, handle hand lever 50 and actual hand lever 1:1 Proportionality design; Travel switch 62, is arranged in the action slot of each manipulation hand lever the position of inductive control hand lever, output switching signal; Pressure sensor 61, is connected with described manipulation hand lever, and the pressure signal of handling hand lever is converted to electric signal; Described travel switch 62 is complete corresponding setting with pressure sensor 61; Electronic switch 63, its control end is connected to described travel switch, and its passage two ends are connected respectively to described pressure sensor 61 and AD converter 70; Dsp processor 80, is connected to described AD converter, and pressure signal is encoded; The first gateway 91, is transferred to pressure code signal the control box of a tower crane high position; Described control box comprises the second gateway 92, receives described pressure code signal; PLC controller 93, according to startup and the rotating speed of respective electrical motivation in described pressure signal control motor unit 95.
