Abstract
The utility model discloses a kind of control system eliminating coupling phenomenon, comprise power supply, motor rotates forward relay, motor reversal relay, hydraulic driver relay, lifting motor and hydraulic driver, described lifting motor rotates forward relay by motor in parallel, motor reversal relay is connected with power supply, and hydraulic driver is connected with power supply by hydraulic driver relay.The utility model effectively can remove the coupling phenomenon between lifting motor and hydraulic driver, realizes the fixed type one direction running of hydraulic driver, reduces the damage rate of hydraulic driver.
Description
Technical field
The utility model relates to a kind of control system, specifically a kind of control system eliminating coupling phenomenon.
Background technology
In present running brake, comprise lifting motor, hydraulic driver and band-type brake, the effect of lifting motor drives driving to rise and declines, and the effect of hydraulic driver is after lifting motor is cut off the electricity supply, promote the rotor that lifting motor held tightly by band-type brake, makes it stop operating rapidly.
The control system of existing running brake, its groundwork as shown in Figure 1, the U phase of power supply, V phase rotate forward relay K 1 with W phase by motor and are connected with hydraulic driver M2 with lifting motor M1, and W phase, the U phase of power supply are connected with hydraulic driver M2 with lifting motor M1 by motor reversal relay K 2 with V phase.When motor rotating forward relay K 1 closes, lifting motor M1 and hydraulic driver M2 rotates forward simultaneously, and when motor reversal relay K 2 closes, lifting motor M1 and hydraulic driver M2 reverses simultaneously.Lifting motor M1 rotates and reverse the rise and fall that can drive driving, but the effect of hydraulic driver M2 promotes the rotor that lifting motor held tightly by band-type brake after lifting motor M1 closes, make it stop operating, therefore it does not need to switch between rotating and reverse at once.And forward and reverse work can cause coming off of spindle captacula in hydraulic driver M2 frequently, and the wearing and tearing etc. of axle connecting rod, cause its loss ratio constantly to raise.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of control system eliminating coupling phenomenon.
In order to solve the technical problem, the technical solution adopted in the utility model is: a kind of control system eliminating coupling phenomenon, comprise power supply, motor rotates forward relay, motor reversal relay, hydraulic driver relay, lifting motor and hydraulic driver, described lifting motor rotates forward relay by motor in parallel, motor reversal relay is connected with power supply, hydraulic driver is connected with power supply by hydraulic driver relay, and motor rotates forward relay, motor reversal relay is in parallel with hydraulic driver relay.
The beneficial effects of the utility model: the lifting motor in the utility model and hydraulic driver are connected with power supply respectively by independently relay, the lifting motor made and the rotation of hydraulic driver separate, no longer there is coupling phenomenon, hydraulic driver can complete the running of fixed type one direction, because this reducing the damage rate of hydraulic driver, prevent the wearing and tearing of the coming off of spindle captacula in hydraulic driver, axle connecting rod, make hydraulic driver unit damage rate be close to zero level.
Accompanying drawing explanation
As the control system schematic diagram that Fig. 1 is prior art;
If Fig. 2 is control system schematic diagram provided by the utility model;
In figure: K1, motor rotate forward relay, K2, motor reversal relay, K3, hydraulic driver relay, M1, lifting motor, M2, hydraulic driver.
Detailed description of the invention
Illustrate that the present invention is described further and limit with detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 2, for the control system of the elimination coupling phenomenon that the utility model provides, in this control system, the U phase of power supply, V phase rotate forward relay K 1 with W phase by motor and are connected with lifting motor M1, W phase, the U phase of power supply are connected with lifting motor M1 by motor reversal relay K 2 with V phase, U phase, the V phase of power supply are connected with hydraulic driver M2 by hydraulic driver relay K 3 with W phase, are parallel relationship between K1, K2 and K3.When closing hydraulic driver relay K 3, hydraulic driver M2 can complete the running of fixed type one direction, no longer coupling phenomenon is there is between the rotary state of its rotary state and lifting motor M1, achieve the function that the utility model eliminates coupled relation between lifting motor and hydraulic driver, reduce the damage rate of hydraulic driver.
The above embodiment is only preferred embodiment of the present utility model, those skilled in the art are according to the utility model improvement of making of spirit and optimization, as replaced relay with other on-off elements, changing the order of connection etc. of three-phase electricity and lifting motor and hydraulic driver, all should be included in scope of the present utility model.
