Abstract
The utility model discloses a variable frequency PLC (Programmable Logic Controller) controlled multipoint lifting crane, comprising a crane main body, two moving blocks, two frequency converters, two motors, a PLC, an operating platform and a displayer. By the operating platform, the PLC is used for controlling the two moving blocks to move back and forth on a guide rail; the two moving blocks can work at any different position; the two frequency converters are also controlled by the PLC; the two motors are controlled through the frequency converters so as to automatically regulate the loaded lifting speed and the no-load lifting speed; and an operator can clearly know the lifting position of the crane, so that the diversification of the lifting point positions is realized, the crane is more convenient and safe to operate, and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of frequency conversion PLC control multiple spot lifting hoisting crane.
Background technology
At present, the goliath on the building ground, lifting speed is slow, single, and the Heave Here is few, inconvenient operation, the operator is dry as dust, inefficiency, safety factor is low.
Summary of the invention
The technical matters that the utility model will solve provides and a kind ofly can solve the crane operation person is dry as dust, increases work efficiency the variable ratio frequency changer PLC control multiple spot lifting hoisting crane of safety of operation.
The utility model is realized through following technical scheme: a kind of variable ratio frequency changer PLC control multiple spot lifting hoisting crane; Comprise hoisting crane body, two movable blocks, two frequency converters, two motors, PLC controller, operator's station and telltales; On the overhanging cantilever of said hoisting crane body movably guide rail is arranged; On the said hoisting crane body operator's compartment is arranged; Said two movable blocks are installed on the guide rail; Said two motors are installed in respectively on described two movable blocks.
As optimized technical scheme, said PLC controller is installed in the operator's compartment the inside.
As optimized technical scheme, said two frequency converters are installed in the operator's compartment the inside side by side.
As optimized technical scheme, said operator's station is installed in the right in the operator's compartment; Said telltale is installed in the left side of operator's station.
The beneficial effect of the variable ratio frequency changer PLC control multiple spot lifting hoisting crane of the utility model is: through operator's station, control two movable blocks with the PLC controller and on guide rail, move around, two movable blocks can be in diverse location work arbitrarily; With two frequency converters of PLC controller control; Through two electrical motors of Frequency Converter Control, automatically regulating load and unloaded lifting speed, the operator clearly understands the lifting position of hoisting crane through telltale; Reach the variation of position, Heave Here; More convenient to operate, safety is increased work efficiency.
Description of drawings
In order to be easy to explanation, the utility model by following specific embodiment and accompanying drawing as detailed description:
Fig. 1 is the variable ratio frequency changer PLC control multiple spot lifting hoisting crane of the utility model.
The specific embodiment
As shown in Figure 1, a kind of variable ratio frequency changer PLC control multiple spot lifting hoisting crane of the utility model comprises hoisting crane body 1, two movable blocks 2, two frequency converters (not shown), two motors 5, PLC controller (not shown), operator's station 3 and telltales 4; Movably guide rail 7 is arranged on the overhanging cantilever of said hoisting crane body 1; On the said hoisting crane body 1 operator's compartment 6 is arranged; Said two movable blocks 2 are installed on the guide rail 7; Said two motors 5 are installed in respectively on described two movable blocks 2.
Wherein, said PLC controller (not shown) is installed in operator's compartment 6 the insides; Said two frequency converters (not shown) are installed in operator's compartment 6 the insides side by side; Said operator's station 3 is installed in the right in the operator's compartment 6; Said telltale 4 is installed in the left side of operator's station 3.
The beneficial effect of the variable ratio frequency changer PLC control multiple spot lifting hoisting crane of the utility model is: through operator's station, control two movable blocks with the PLC controller and on guide rail, move around, two movable blocks can be in diverse location work arbitrarily; With two frequency converters of PLC controller control; Through two electrical motors of Frequency Converter Control, automatically regulating load and unloaded lifting speed, the operator clearly understands the lifting position of hoisting crane through telltale; Reach the variation of position, Heave Here; More convenient to operate, safety is increased work efficiency.
The foregoing description, just a case of this practicality is not enforcement and the interest field that is used for limiting the utility model, all identical technical schemes that are equal to the said content of the utility model claim all should be included in the utility model protection domain more.
