The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of hydraulic tongs protector, main solution pump 1 Bonding pressure torque meter 4, overflow valve 2 and torque adjusting valve 3, main solution pump 1 connects ball-and-seat and snap joint 12, the other end of ball-and-seat and snap joint 12 connects 3-position 4-way hand-operated direction valve 11 and stroke valve 5, the other end of 3-position 4-way hand-operated direction valve 11 connects two-position four-way pilot operated valve device 10, the other end of two-position four-way pilot operated valve device 10 connects main pincers reversing motor 8 and back-up tong oil cylinder 9, two-position four-way pilot operated valve device 10 connects stroke valve 5
Z-shaped stroke valve fixed mount 13 connects swash plate 23, and Z-shaped stroke valve fixed mount 13 has 2 fixed mount fixing holes 14 to distribute, and swash plate 23 has 2 stroke valve fixing holes 15 to distribute;
Extension bar 21 connects buting iron 6, and extension bar 21 has 2 set bolts 20 to connect,
Two-position four-way pilot operated valve device 10 is valve plate type, two-position four-way pilot operated valve device 10 fronts communicate with the valve plate valve opening is corresponding, corresponding the communicating of valve opening of two-position four-way pilot operated valve device 10 back and 3-position 4-way hand-operated direction valve 11, two-position four-way pilot operated valve device 10 two sides communicate with spool by oblique hole.
The swash plate 23 of buting iron is ramp type, adjustable up and down, the wearing and tearing of compensation stroke valve valve rod and buting iron.By extension bar, be fixed on safety door,
Be connected stroke valve 5 at the left front guide rod of hydraulic tongs with the body junction, by safety door 7, control stroke valve 5.Be connected two-position four-way pilot operated valve device 10 between 3-position 4-way hand-operated direction valve 11 and valve plate.Safety door 7 is opened, and stroke valve 5 spools move under the effect of spring, and the oil pocket P of stroke valve 5 and oil pocket B are logical, and it is obstructed that two-position four-way pilot operated valve device 10 is closed the ，Ye road, and hydraulic tongs does not turn.When safety door 7 is closed, the guide rod that stroke valve 5 spools are fixed on safety door 7 is depressed, and just makes the oil pocket P of stroke valve 5 and oil pocket A logical; Control two-position four-way pilot operated valve device 10 spools and press to left side, two-position four-way pilot operated valve device 10 is logical, does not affect the hand-operated direction valve operation.
