Abstract
The utility model relates to a latch-up protection device of a double-tank operating crane. The latch-up protection device of the double-tank operating crane comprises a single-tank operating crane control unit and a double-tank operating crane control unit. The single-tank operating crane control unit comprises a safety door in-place switch K and a control relay J, and the safety door in-place switch K is in series connection with the control relay J and a normally-closed contact J11 of the control relay J. The double-tank operating crane control unit comprises an operating crane beating and connecting button K2 and an operating crane latch-up button K1, the operating crane beating and connecting button K2 is in parallel connection with the normally-closed contact J11 of the control relay J, and a loop is formed by the operating crane latch-up button K1 and the normally-closed contact J11 of the control relay J. The latch-up protection device of the double-tank operating crane can ensure the safety of personnel descended in a well.
Description
Technical field
The utility model relates to mechanical device protection field, particularly relates to the two tank behaviour of auxiliary shaft car latch-up protection device.
Background technology
Behaviour's car is divided into single tank behaviour's car and two tank behaviour car, and wherein single tank behaviour car is used for up and down personnel and material, and two tank behaviour cars are used for up and down personnel and mine car etc.But in the middle of reality was used, single tank behaviour's car and two tanks behaviour cars there will be the situation of working simultaneously, and when on single tank behaviour car during the servant, two tanks behaviour cars are likely just in time grasped the car operation, easily the people are caused accidental injury.
Summary of the invention
For above-mentioned situation, the purpose of this utility model is to provide a kind of pair of tank behaviour car latch-up protection device, guarantees the personnel's that go into the well safety.
the technical solution of the utility model is as follows: two tank behaviour car latch-up protection devices, comprise single tank behaviour car control unit and two tank behaviour car control unit, described single tank behaviour car control unit comprises safety door location switch k, control relay J, the described safety door K switch that puts in place is connected in series with the normally closed contact J11 of control relay J and control relay respectively, two tank behaviour car control units comprise that grasping car beats even button K2 and behaviour's car latch buttons K1, behaviour's car is beaten the normally closed contact J11 that connects button K2 and control relay J and connects, the normally closed contact J11 of behaviour car latch buttons K1 and control relay J forms loop.
Preferably, described control relay is the MT-K16 relay.
Of the present utility model pair of tank behaviour car latch-up protection device, when the single tank safety door in shaft bottom is closed, location switch K closes, signal reaches the control relay J of single tank behaviour car control unit in single tank car room, control relay J normally closed contact J11 disconnects, the locked loop that shaft bottom two tank behaviour car control unit behaviour car latch buttons K1 and control relay J normally closed contact J11 form disconnects, and car can be normally grasped in two tanks shaft bottom; When the single tank safety door in shaft bottom is closed when not in place, instruction sheet tank safety door is opened, likely there is the people to pass in and out from single tank, this moment, location switch K opened, and signal reaches the control relay J of single tank behaviour car control unit in single tank car room, and control relay J normally closed contact J11 is closed, at this moment the car locked loop is grasped by behaviour's car latch buttons K1 connection in two tank shaft bottoms, the behaviour's car locking of two tanks shaft bottom, can't normally grasp car, to guarantee the personnel's of going into the well safety.When single tank safety door et out of order, normally grasp car in order not affect two tanks, press two tank behaviour cars and beat even button K2, two tanks shaft bottom behaviour's car locked loop and single tank safety door location switch can't form locking, can normally grasp car, not affect two tank behaviour cars and normally produce.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
as shown in Figure 1, two tank behaviour car latch-up protection devices, comprise single tank behaviour car control unit and two tank behaviour car control unit, described single tank behaviour car control unit comprises safety door location switch k, MT-K16 control relay J, the described safety door K switch that puts in place is connected with the normally closed contact J11 of MT-K16 control relay J and MT-K16 control relay respectively, two tank behaviour car control units comprise that grasping car beats even button K2 and behaviour's car latch buttons K1, behaviour's car is beaten the normally closed contact J11 that connects button K2 and MT-K16 control relay J and connects, the normally closed contact J11 of behaviour car latch buttons K1 and MT-K16 control relay J forms loop.
During concrete the use, when the single tank safety door in shaft bottom is closed, location switch K closes, signal reaches the MT-K16 control relay J in single tank behaviour car control unit 1 in single tank car room, MT-K16 control relay J normally closed contact J11 disconnects, the locked loop that two tank behaviour car behaviour car latch buttons K1 of shaft bottom two tank behaviour car control unit 2 and MT-K16 control relay J normally closed contact J11 form disconnects, and car can be normally grasped in two tanks shaft bottom; When the single tank safety door in shaft bottom is closed when not in place, location switch K opens, signal reaches the MT-K16 control relay J in single tank behaviour car control unit 1 in single tank car room, MT-K16 control relay J normally closed contact is closed, at this moment pair tank shaft bottoms behaviour's car locked loop is by behaviour's car latch buttons K1 connection of two tanks behaviour car control units 2, the behaviour's car locking of two tanks shaft bottom, can't normally grasp car.When single tank safety door et out of order, normally grasp car in order not affect two tanks, to press two tank behaviour cars and beat even button K2, two tanks shaft bottom behaviour's car locked loop and single tank safety door location switch can't form locking, can normally grasp car.
Claims (2)
1. two tanks are grasped car latch-up protection devices; it is characterized in that comprising single tank behaviour car control unit and two tank behaviour car control unit; described single tank behaviour car control unit comprises safety door location switch k, control relay J; the described safety door K switch that puts in place is connected in series with the normally closed contact J11 of control relay J and control relay respectively; two tank behaviour car control units comprise that grasping car beats even button K2 and behaviour's car latch buttons K1; behaviour's car is beaten the normally closed contact J11 that connects button K2 and control relay J and connects, and the normally closed contact J11 of behaviour car latch buttons K1 and control relay J forms loop.
