Embodiment 1

[0062] like Figure 1 to Figure 17 As shown, a kind of power catwalk of the present embodiment comprises ramp 1, base 2, cloud beam 3, cantilever 4, leg 5 and main drive system; Wherein: the bottom end of described ramp 1 and described base 2, the front end of the cloud beam 3 is matched with the front of the ramp 1 and can move up and down along the front of the ramp, the upper end of the cantilever 4 is flexibly connected with the rear position of the cloud beam 3, The lower end of the cantilever 4 is movably connected with the base 2, the cloud beam 3 can be driven to move up and down along the ramp 1 through the main drive system, and the legs 5 are arranged on the side of the base 2 In the direction, the rear end of the leg 5 is close to the base 2, and it also includes a bracket 9 that can be arranged to support the drilling tool. The front end of the leg 5 is arranged with the bracket 9, and the leg 5 is assembled There is a hook assembly for hooking the drill supporte...

Embodiment 2

[0078] Based on the design of Embodiment 1, such as Figure 1 to Figure 17 As shown, in the power catwalk of this embodiment, the base frame is a liftable structure, and the support plate can be driven to move up and down through the lifting of the base frame. The support plate 52 can be lowered to a lower position by lowering the base frame, and the support plate 52 can be raised to a higher position by raising the base frame. When the design of this embodiment is adopted, when the bracket 9 is arranged with multi-layer drilling tools, the support plate 52 is raised by the base frame, so that the support plate 52 is substantially flush with the bottom surface of the topmost drilling tool, as Figure 13 As shown, the drilling tool closest to the front end of the support plate 52 is hooked to the support plate 52 of the support leg 5 through the hooking component (after the hooking component hooks the drilling tool closest to the support leg 5, it can be Push the layer of dril...

Embodiment 3

[0082] Based on the design of embodiment one or embodiment two, such as Figure 1 to Figure 19As shown, a kind of power catwalk of the present embodiment, the rear end of described base 2 is provided with the towing frame 7 that is used to connect trailer, and the front end of described base 2 is provided with the towing wheel that is used to make described base walk Assembly8. When the power catwalk needs to be transferred between well sites, the trailer is driven to the position of the trailer traction frame 7 and connected with the trailer. At this time, the power catwalk can be towed and transferred to the target well site through the trailer, and the power catwalk can be realized. The transfer between well sites does not require large-scale hoisting operations, and the transfer operation is safer, more reliable, more convenient and quicker. In practical engineering applications, when the power catwalk is connected to the drill floor, the upper end of the ramp 1 will be c...

Abstract

The invention discloses a power catwalk, which belongs to the technical field of oil and gas drilling equipment. A power catwalk of the present invention includes a ramp, a base, a cloud beam, a cantilever, legs and a main drive system, and also includes brackets that can be arranged to support drilling tools, and the brackets are arranged at the front ends of the legs , the supporting leg is equipped with a hooking assembly capable of hooking the drilling tool supported on the bracket to the supporting leg. The power catwalk of the present invention has the basic drilling tool delivery function of the power catwalk in the prior art, and thanks to the design of the bracket and the hook assembly assembled on the legs, the bracket can be arranged to support the drilling tool , Through the hook assembly assembled on the outrigger, the drilling tools arranged and supported on the bracket can be hooked to the outrigger without using a pipe grabber, which is more convenient and quicker, can improve the conveying efficiency of the drilling tool and reduce the working cost.

Description

technical field [0001] The invention relates to a power catwalk, which belongs to the technical field of oil and gas drilling equipment. Background technique [0002] The power catwalk is a conveying equipment used in the technical field of oil and gas drilling and production equipment. It can transport the drilling tools on the legs on both sides of the power catwalk to the drill floor, and can also transport and arrange the drilling tools on the drill floor to the power catwalk. On the outriggers on both sides of the road; as a kind of power catwalk disclosed by Chinese patent, application number CN201520866530.4; a kind of oil cylinder lifting type land power catwalk disclosed by Chinese patent, application number CN201420525189.1; A rack-and-pinion drill power catwalk, application number CN201420660266.4 and so on. [0003] Refer to and be not limited to the power catwalk disclosed above, the typical structure of the power catwalk is: including ramp, base, cloud beam, c...
