Detailed Description

The utility model is shown in figures 1-4 and comprises an oil pipe base 1, an elastic layer 2, an oil pipe pressing plate 3 and a pair of hinged plates 4;

the hinge plates 4 are vertically and symmetrically fixedly arranged on the crane boom;

the oil pipe base 1 is hinged between the pair of hinge plates 4; the oil pipe seat 1 is U-shaped, and the middle part of the oil pipe seat is provided with an accommodating groove matched with the oil pipe; the size of the fixed seat is designed according to the specification and the number of the oil pipes 8;

the elastic layer 2 is arranged between the oil pipe 8 and the oil pipe pressing plate 3;

the oil pipe pressing plate 3 is matched with the oil pipe seat 1, and the oil pipe 8 is fixed in the oil pipe seat 1 through the fixed connection of the oil pipe pressing plate 3 and the oil pipe seat 1.

This case makes oil pipe 8 be fixed in on the flexible arm through the cooperation of oil pipe seat 1 and oil pipe clamp plate 3, realizes oil pipe 8 and follows the rotation of flexible arm adaptation through the articulated realization between oil pipe seat 1 and the articulated slab 4, promotes oil pipe 8's life. The size of the oil pipe seat 1 can be designed according to the specification of the pipe, the safety of the oil pipe 8 can be improved through the built-in elastic cushion, and the risk of friction damage is reduced.
