Technical Field

[0001] The utility model relates to the technical field of oil and gas drilling, in particular to an iron roughneck sliding device and an iron roughneck with the same. Background Art

[0002] The iron roughneck is an important wellhead automation equipment in the oil drilling industry. It is mainly used to make and break out the drill tools during the process of drilling. Since the iron driller needs to be close to the wellhead during operation and needs to be away from the wellhead after the operation is completed, in order to achieve the iron roughneck close to or away from the wellhead, the commonly used methods include telescopic arm type and track type. The iron roughneck is often divided into telescopic arm iron roughneck and track type iron roughneck. The telescopic arm iron roughneck has a compact structure and can achieve make-up and breakout operations at two positions, the wellhead and the rathole. However, the telescopic arm has a limited telescopic distance. When the telescopic arm is retracted, the iron roughneck is close to the wellhead, occupying the working space of other wellhead equipment. The track length of the track-type iron roughneck can be customized, and it is far away from the wellhead when retracted, but it can usually only achieve make-up and breakout operations at one position of the wellhead, and the track occupies a large area.

[0003] Therefore, there is an urgent need for an iron roughneck sliding device which occupies a small area and can simultaneously meet the operating requirements of the iron roughneck wellhead and rathole position, and an iron roughneck having the same. Utility Model Content

Among them, the directional nouns such as "front" and "back" mentioned in this article are as follows: Figure 1 The orientation is used as a reference.

[0036] Embodiment 1:

[0037] like Figure 1-Figure 4 As shown, this embodiment provides an iron roughneck sliding device, including a track assembly 1, a moving trolley 2 and a driving assembly 3; the iron roughneck body 4 can be installed on the moving trolley 2, and the moving trolley 2 can be installed on the track assembly 1 to move forward and backward, and the track assembly 1 has a first rack 11 extending in the front-back direction, and the bottom of the moving trolley 2 is provided with a second rack 21 corresponding to the first rack 11 up and down, and the second rack 21 faces the first rack 11; the driving assembly 3 includes a telescopic driver 31 and a gear 32; the telescopic driver 31 is installed on the track assembly 1, and the telescopic driver 31 is connected between the first rack 11 and the second rack 21 through the gear 32. In this embodiment, the telescopic driver 31 is a hydraulic telescopic driver.

[0038] Specifically, the telescopic arm or rail-type iron driller body 4 is installed on the mobile trolley 2. The mobile trolley 2 is driven by the driving component 3 to drive the iron driller body 4 to move forward along the track assembly 1 to a standby position. At this time, the iron driller body 4 can be in two states, standby and working, to meet the requirements of the make-up and make-off operations of the wellhead or rathole drilling tool 6; the mobile trolley 2 is driven by the driving component 3 to slide backward along the track to a rest position. At this time, the iron driller body 4 is in a standby state. The rest position of the mobile trolley 2 is farther from the wellhead than the standby position, providing more working space for the operation of other wellhead equipment. The telescopic driver 31 of the driving assembly 3 drives the gear 32 to move forward and backward, and the gear 32 rotates to mesh with the first rack 11 and the second rack 21. The stroke of the second rack 21 is twice the stroke of the telescopic driver 31, which produces an extended range effect to drive the mobile trolley 2 to move forward and backward. Therefore, the telescopic driver 31 with a shorter stroke can achieve a larger moving stroke effect. Therefore, the telescopic driver 31 occupies less space, has a more compact structure, and occupies a smaller area of ​​the drilling floor 5 as a whole, which is convenient for layout. Compared with the prior art, it can make the iron roughneck main body 4 take into account the advantages of traditional telescopic arm iron roughneck and rail iron roughneck, occupy a small area of ​​the drilling floor 5, and is easy to install and maintain.

[0039] Furthermore, if Figure 6 As shown, the mobile trolley 2 includes a trolley body 22, a roller set 23 and a mounting seat 24.

In this embodiment, there are four rollers in the roller set 23, and the trolley body 22 is movably supported on the track assembly 1 through the four rollers. The track assembly 1 can not only withstand the gravity of the mobile trolley 2 and the iron roughneck body 4 mounted thereon, but also withstand the torque generated by the iron roughneck body 4 because its center of gravity is outside the four roller support points.

[0040] Furthermore, if Figure 5 As shown, the track assembly 1 includes a track body 12 and a connection assembly; the connection assembly is fixed to the track body 12, and the track body 12 can be installed on the drilling floor 5 through the connection assembly; the first rack 11 is installed on the track body 12. In this embodiment, the connection assembly includes a plurality of connection plates 13 and a plurality of connection seats 14; the plurality of connection plates 13 are evenly distributed at the bottom of the track body 12, and the plurality of connection seats 14 are evenly distributed at the side of the track body 12.

[0041] Furthermore, if Figure 5 and Figure 6As shown, the front and rear ends of the mobile trolley 2 are provided with a front proximity switch 25 and a rear proximity switch 26 respectively; the track assembly 1 is provided with a front switch detection plate 15 and a rear switch detection plate 16 correspondingly; the front proximity switch 25 and the rear proximity switch 26 are connected to the telescopic drive 31. In this embodiment, the track assembly 1 is provided with a front limit block 17 and a rear limit block 18, the front switch detection plate 15 is installed on the track assembly 1 through the front limit block 17, and the rear switch detection plate 16 is installed on the track assembly 1 through the rear limit block 18. Specifically, the front limit block 17 is provided at the front end of the track body 12, the rear limit block 18 is provided at the rear end of the track body 12, the front proximity switch 25 is provided at the front end of the trolley body 22, and the rear proximity switch 26 is provided at the rear end of the trolley body 22. The driving assembly 3 drives the trolley body 22 to move forward along the track body 12 until its front proximity switch 25 detects the front switch detection plate 15, and the front proximity switch 25 stops the telescopic drive 31, and the trolley body 22 reaches the standby position. Similarly, the driving assembly 3 drives the trolley body 22 to move backward along the track body 12 until its rear end proximity switch 26 detects the rear end switch detection plate 16, and the rear end uses the switch to stop the telescopic drive 31, and the trolley body 22 reaches the rest position.

[0042] Furthermore, if Figure 7 As shown, the driving end of the telescopic actuator 31 is provided with an ear seat 33, and the gear 32 is rotatably mounted on the ear seat 33 through a pin shaft 34, and its rotation axis is oriented transversely.
