Abstract
The utility model belongs to the technical field of mechanical devices, and particularly relates to a position limiting device for a ball mill lining plate mounting and dismounting transfer trolley. The position limiting device comprises a pump station electric control device and a manual reversing valve, wherein the pump station electric control device controls the transfer trolley to do reciprocating movement. The position limiting device is characterized in that the pump station electric control device is connected with two proximity switches and one electromagnetic overflow valve, the two proximity switches are respectively arranged at two end plates of an inner cavity of a ball mill, sensing metal plates corresponding to the two proximity switches are respectively arranged on the transfer trolley, and the electromagnetic overflow valve is respectively connected with a hydraulic pump station and the manual reversing valve. The position limiting device has the advantages that the transfer trolley can be precisely stopped in a required position, so the damage caused by collision of each component is avoided, the work efficiency is improved, and the energy sources are saved.
Description
Technical field
The utility model belongs to the technical field of mechanical device, especially relates to a kind of inhibiting device of ball grinding machine lining board dismounting transport carriage.
Background technology
Large-size ball mill is changed liner plate and need be relied on the liner plate disassembly robot to complete, as the Anshan iron and steel plant Qidashan iron ore from 2 these equipment of external introduction.The main working parts of liner plate disassembly robot is rotary crane, girder and can be on girder reciprocating dolly.
During the dismounting liner plate, this machine relies on walking and the adjusting mechanism of self, and rotary crane and the girder head that will be positioned at the girder head are transferred to ball grinding mill, and the liner plate under rotary crane will be dismantled is placed on dolly, and dolly moves to the girder afterbody, and liner plate is sent outside ball grinding mill; When liner plate is installed, operation order is opposite.
The dolly that is used at present transporting liner plate is controlled by the hydraulic efficiency pressure system hand change over valve by the operator.During to girder head or afterbody two position, the handle that the operator should in time unclamp hand change over valve just can make dolly out of service when trolley travelling.But in actual use, for various reasons, especially trolley travelling often can not in time unclamp the handle of hand change over valve to girder head (in ball grinding mill, unsighted) operator, just can be out of service when encountering end baffle when making trolley travelling to girder head or afterbody two position.Cause so following drawback:
1, long-term operation causes girder two end-stopping plates and dolly face deformation to damage;
2, system produces hydraulic efficiency impact, and hydraulic part reduces service life;
3, dolly off-position inaccuracy, affect work efficiency; Waste energy.
Summary of the invention
The purpose of this utility model is to provide a kind of inhibiting device of ball grinding machine lining board dismounting transport carriage, improves the automatization level of this machine operation, makes the dolly off-position accurate, increases work efficiency, and extends each parts service life.
The purpose of this utility model realizes by following technical proposals:
The inhibiting device of ball grinding machine lining board dismounting transport carriage of the present utility model, comprise and control pumping plant controller for electric consumption and the hand change over valve that transport carriage moves back and forth, it is characterized in that described pumping plant controller for electric consumption is connected with an electromagnetic relief valve with two approach switchs, described two approach switchs are located at respectively ball grinding mill inner chamber two end plates place, be respectively equipped with two induction metal sheets that approach switch is corresponding therewith on transport carriage, described electromagnetic relief valve is connected with hand change over valve with hydraulic power unit respectively.
Advantage of the present utility model:
The utility model can make transport carriage accurately stop in the demand position, thereby avoiding each components hit to produce damages, increase work efficiency, energy savings.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
as shown in Figure 1, the inhibiting device of ball grinding machine lining board dismounting transport carriage of the present utility model, comprise and control pumping plant controller for electric consumption and the hand change over valve 2 that transport carriage 11 moves back and forth, it is characterized in that described pumping plant controller for electric consumption is connected with an electromagnetic relief valve 3 with two approach switchs 8, described two approach switchs 8 are located at respectively ball grinding mill inner chamber two end plates 7 places, be respectively equipped with two induction metal sheets 10 that approach switch is corresponding therewith on transport carriage 11, described electromagnetic relief valve 3 is connected with described hand change over valve 2 with hydraulic power unit 1 respectively.Number in the figure 4 expression HM Hydraulic Motor; Label 5 expression drive sprockets; Label 6 expression driving chains; Label 9 expression carriage walking girders; Label 12 expression revolution sprocket wheels.During work, hand change over valve 2, transport carriage 11 begins walking, when transport carriage 11 moves to when answering off-position to put, approach switch 8 conductings, signal control electromagnetic relief valve 3 overflows of the sustainable n of PLC system output one second in the pumping plant controller for electric consumption, this moment, the pumping plant delivery pressure was 0, transport carriage is out of service.N signal ended after second (n can according to the actual conditions setting), electromagnetic relief valve finishes overflow, and the operator can proceed operation.
