Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas drilling and production related equipment, in particular to a continuous overhead conveyor. Background Art

[0002] In the process of energy exploration and development, drill pipes, drill collars, casing, tubing and other rods need to be transported from low places to high tables. The existing transportation equipment is mainly catwalks or flat conveyor belts. Catwalks have evolved from the most primitive and common mechanical structure to the power catwalks used today.

[0003] The existing power catwalks are mainly hydraulically driven and electrically driven. The hydraulic drive lifts the box-type beam by installing a hydraulic cylinder at a low position, and transports the rods in the box-type beam to the high-position drilling platform. The electric drive uses a transmission mechanism such as a motor and a reducer to drag the beam to the drilling platform using a ramp. Both forms require the use of a box-type beam. The weight of the beam is many times that of the rod, and the volume is large, making it difficult to carry. The transmission process from a low position to a high position consumes a lot of energy and has low efficiency, resulting in a high operating cost for the drilling and servicing rig. At the same time, with the improvement of the safety requirements for blowout prevention operations of drilling and servicing rigs, the requirements for blowout preventer combinations have increased, and the drilling and servicing rig table has risen accordingly, further increasing its volume and working energy consumption.

[0004] Therefore, it is necessary to develop a continuous overhead conveyor to solve the above problems. Summary of the invention

The bottom of the hinge seat is fixed in position by bolts 512.

[0044] The present application changes the structure in which the original hydraulic or electric driving force directly acts on the box-type beam containing the rods, thereby achieving the purpose of reducing power consumption. At the same time, by setting up an elevated mechanism 5, the weight of the original box-type beam is reduced. Through the innovative chain 22 lifting mechanism and the conveyor belt 15, continuous and efficient operation of the rod transmission is achieved.

[0045] In the present application, the continuous lifting mechanism 2 can be arranged vertically at 90 degrees, tilted at 75 degrees, or tilted at 60 degrees. The hook machine 21 can be installed with the continuous lifting chain 22 through a pin or bolt according to the required position to realize the horizontal lifting and lowering of the rods, and the transfer of the rods between the continuous conveyor belt 15 and the continuous lifting mechanism 2 is realized through the temporary storage flip frame reversing mechanism, so as to realize the safe, continuous, fast, and stable transmission of the rods between the low position and the high position, and the transmission path is unique, so as to ensure the safety of the rod transmission process and improve the transmission efficiency.

[0046] The continuous lifting mechanism 2 is of modular design, and the continuous lifting chain 22, hook machine 21, and motor can be selected according to the diameter, weight, and conveying height of the conveying rod required.

[0047] This application adopts full electric drive, and all drives are performed by motors or electric cylinders. The electric drive form ensures that the action mechanism is fast, accurate and stable. The electric drive eliminates the need for heavy and redundant hydraulic pipelines, reduces weight, and has higher conversion efficiency, thereby further reducing energy consumption.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
