Problems solved by technology
However, the problem of using the vehicle-mounted boom to complete the above-mentioned transfer of oil is that the delivery pipeline needs to adapt to the turning of the boom. Using a hose or a hard pipe connected by a hose is an easy-to-think solution, but it is obviously easy to damage and other disadvantages

Embodiment Construction
[0011] The built-in oil-through rotating device between the articulated arms of this embodiment is as follows: figure 1 As shown, a connecting inlet pipe 8 with an inlet and a connecting outlet pipe 4 with an outlet are included. The connecting inlet pipe 8 is welded with the joint outer ring 1 extending upward. The joint outer ring 1 has a horizontal perforation, bearings 6 are respectively installed at both ends of the horizontal perforation, and a tubular joint inner ring 2 is inserted into the hole and sealed with a sealing ring 5. The middle part of the joint inner ring has a radial protrusion 2- 1. The inner ring 2 of the joint is adjacent to the extended end of the inlet pipe 8 and is screwed with the inner thread of the locking member 7 through the external thread, so as to form the axial limit of the outer ring 1 of the joint together with the radial protrusion 2-1, The inner ring 2 of the joint and the outer ring 1 of the joint form an articulated pair. The inner r...

The invention relates to a built-in oil-connecting rotary device between hinged cantilever cranes, which belongs to the field of liquid conveying technology. The device comprises a connecting inlet pipe and a connecting outlet pipe, an outer joint ring with a horizontal through hole extends out of the connecting inlet pipe, a tubular internal joint ring which is connected in seal and is hinged with the horizontal through hole is inserted into the horizontal through hole, the outer extending section of the internal joint ring extends out of the connecting outlet pipe with an outlet, an inlet is communicated with the outlet through a through hole on the wall of the internal joint ring, a horizontal connecting shaft is inserted in the internal joint ring, and the two ends of the internal joint ring are sealed with the connecting shaft, the two ends of the connecting shaft are respectively sleeved with an internal cantilever crane, and are fixedly connected with an external cantilever crane. In this way, with the device disclosed by the invention, a pipe joint and a folded cantilever crane support can be organically combined to be used for the connection of the cantilever cranes, and also to be used as an oil-connecting device, and the oil-connecting device is ensured not to be affected by radial force. During work, when the folded cantilever crane is unfolded or folded, the oil-connecting pipe can be rotated along with the internal and external cantilever cranes by the built-in oil-connecting rotary device between the hinged cantilever cranes.
Description
technical field [0001] The invention relates to a fluid conveying pipeline, in particular to a built-in oil-passing rotating device between articulated arm frames, belonging to the technical field of liquid conveying. Background technique [0002] According to the applicant's understanding, when the oil is to be transported from the wharf valve well to the ship's oil receiving port (17m away, 7m high), the existing technology leads the oil delivery hose from the wharf valve well, and then uses the wharf crane to transport the oil. The other end of the hose is hoisted to the ship's oil receiving port for connection to the oil pipeline. This oil delivery method is extensive and has poor on-site operability and high operational risk. [0003] The use of collapsible vehicle-mounted booms is one of the feasible measures to solve the transfer and transportation of materials. For relevant prior art, please refer to Chinese patent application documents with application numbers 200...
