Catwalk

Abstract

The invention relates to the field of engineering equipment, in particular to a catwalk for automatically transporting a pipe. The catwalk for automatically transporting the pipe comprises a ramp, a supporting beam, supporting legs and a base. The bottom end of the ramp is movably connected with one end of the base, and the supporting beam is mounted on the base. The center line of the supportingbeam coincides with the center line of the base, and the supporting legs are symmetrically and evenly mounted on both sides of the base. The catwalk for automatically transporting the pipe further comprises M first swinging devices and N second swinging devices, wherein M is greater than or equal to 2, and the first swinging devices are fixedly connected with the base and evenly distributed on twosides of the base; and N is greater than or equal to 1, the second swinging devices are fixedly connected with the supporting beam, the center lines of the second swinging devices coincide with the center line of the supporting beam, the use of two four-bar linkage mechanisms enables the pipe to be not provide with dead point positions in the movement process, the safety of personnel operation isimproved, and transportation track is safe and controllable in the whole process of transporting the pipe, so that the automation degree and efficiency of the equipment are improved, and reliable operation is achieved.

Description

technical field [0001] The invention relates to the field of engineering equipment, in particular to a catwalk for automatically transporting pipes. Background technique [0002] During oil and gas drilling, it is necessary to connect or disassemble a large number of cylindrical tubular tools (hereinafter referred to as "pipes"). The pipes need to be transported from the surface pipe rack to the drilling floor of the drilling rig for conversion. The pipes are disassembled and transported from the drill floor back to the drill rod rack, catwalks are used to transport the pipes. [0003] Transporting pipes is a high-risk and labor-intensive job. The length of the pipe is long and the weight can reach about 4.5 tons. Usually, when the catwalk transports the pipe, the length of the pipe is long and the shape is not a standard round pipe. And other reasons, often cause problems such as the pipe is stuck, the pipe needs to be pushed or flipped artificially, which increases the da...

AI Technical Summary

Problems solved by technology

[0005] 1. There is a dead point position, which is easy to cause the pipe to get stuck, and needs to be turned or pushed manually, which increases the danger of personnel operation;

[0006] 2. After the pipe is stuck, it needs to be adjusted by personnel, which reduces the work efficiency
