Fig. 2 is the structural representation of the Power Tong automatically-controlled door folding condition in the utility model；
Fig. 3 is the structural representation of the control system in the utility model.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and specifically
Embodiment, the utility model is further elaborated.It should be appreciated that embodiment described herein is only used
To explain the utility model, it is not used to limit the utility model.
Referring to Fig. 1, Fig. 2 and Fig. 3, present embodiment discloses a kind of Power Tong automatically-controlled door closing device, including lock
Tight door hydraulic cylinder 1, switching door hydraulic cylinder 2, Power Tong protective door 8, proximity switch 9, door shield block 10 and control system 11, control system
System 11 is connected with locking door hydraulic cylinder 1 and switching door hydraulic cylinder 2 respectively, and Power Tong protective door 8 includes left locking door 81 and the right side is opened
Door 82 is closed, left locking door 81 and right switching door 82 are fixed on Power Tong housing 83 by door-hinge respectively, locking door hydraulic cylinder 1
Piston rod head part is connected with the shaft portion of left locking door 81, the piston rod head of switching door hydraulic cylinder 2 respectively with right folding
