Technical Field

The invention relates to a guide rail assembly, a pulley guide rail assembly structure adopting the same and a power catwalk of the pulley guide rail assembly structure, and belongs to the technical field of power catwalks.

Background

The power catwalk is conveying equipment used in the technical field of oil and gas drilling equipment, and can convey drilling tools on supporting legs (supporting legs can also be called bent frames) on two sides of the power catwalk to a drilling platform surface and also convey and arrange the drilling tools on the drilling platform surface to the supporting legs on two sides of the power catwalk; such as chinese patent CN201520866530.4, a power catwalk; chinese patent CN201420525189.1, an oil cylinder lifting type land power catwalk; chinese patent CN201420660266.4, a rack and pinion drill power catwalk.

The main driving system of the power catwalk is a driving system used for lifting a power catwalk cloud beam (the power catwalk cloud beam can also be called a V-shaped drilling tool supporting beam). The up-and-down motion of the pulley of the main driving system can drive the lifting of the cloud beam of the power catwalk.

In order to enable the trolley to move in a given direction when the trolley is moved by the driving mechanism, the trolley is generally required to be mounted on a guide rail, which serves as a guide, and the structure of the trolley is shown in fig. 5. The bottom two sides of the pulley are provided with roller discs (the upper side of each roller disc is provided with a roller, and the lower side of each roller disc is also provided with a roller), the roller discs on the bottom two sides of the pulley are respectively clamped and embedded on the side part of the guide rail in a sliding manner, specifically, the roller on the upper side of each roller disc is attached to the top surface of the guide rail, and the roller on the lower side of each roller disc is attached to the bottom surface of the guide rail.

Generally, the wings of the guide rail are usually made of a plate material having an equal thickness. For large-scale mechanical equipment (such as a power catwalk), in order to meet the requirement of use strength, the thickness of the wing plate is thick, the material consumption is large, and the weight of the guide rail is heavy.

For the guide rail with the structure, the main bearing parts are positioned at the two sides of the guide rail, so that the invention provides a guide rail assembly with a brand new design, which can meet the use strength, save materials and reduce the weight of the guide rail assembly.

Disclosure of Invention

The invention aims to: aiming at the existing problems, the invention provides the guide rail assembly, the pulley guide rail assembly structure adopting the guide rail assembly and the power catwalk.

The technical scheme adopted by the invention is as follows:

a guide rail assembly comprises a first guide rail and 2 second guide rails; the guide rail I comprises a web plate I and an upper wing plate I arranged at the upper end of the web plate I, and the guide rail II comprises a web plate II, an upper wing plate II and a lower wing plate II which are arranged at the upper end and the lower end of the web plate II; and 2, the upper wing plates of the second guide rails are respectively connected to two sides of the upper wing plate I of the first guide rail, and the wall thickness of the upper wing plates is greater than that of the upper wing plates.

In the guide rail assembly, 2 guide rails II are connected to two sides of a first guide rail along the length direction of the first guide rail, specifically, upper wing plates II of the 2 guide rails II are respectively connected to two sides of the upper wing plates I of the first guide rail, and the wall thickness of the upper wing plates II is greater than that of the upper wing plates I; the first guide rail mainly plays a role in connecting the second 2 guide rails, so that the guide rail assembly forms an integral structural form, and the second guide rail is used for directly bearing the weight. When the pulley in the background technology is arranged on the guide rail assembly, the pulley can directly act on the second guide rail; specifically, the pulley directly acts on an upper wing plate II and a lower wing plate II of the guide rail II; particularly, the second upper wing plate needs to bear the weight of the pulley directly, so that the guide rail assembly is stable in structure, can meet the requirement of use strength, saves materials, reduces manufacturing cost and lightens the weight of the guide rail assembly due to the integral design of the guide rail assembly, particularly the design that the wall thickness of the second upper wing plate is larger than that of the first upper wing plate.

Preferably, the wall thickness of the second lower wing plate is greater than that of the first upper wing plate. When the pulley is installed on the guide rail assembly, the pulley can directly act on the second lower wing plate, so that the wall thickness of the second lower wing plate is larger than that of the first upper wing plate, which is a preferable design.

Furthermore, the first guide rail further comprises a first lower wing plate arranged at the lower end of the first web plate. The lower wing plate I plays a role in supporting the web plate I and the upper wing plate I, and the structural stability of the guide rail assembly is improved.

Furthermore, a plurality of support plates are connected between the first guide rail and the second guide rail 2 along the length direction of the guide rail assembly. The support plate can play a role in connecting and supporting the first guide rail and the second guide rail, and the structural stability of the guide rail assembly is improved.

Optionally, a plurality of lightening holes are formed in the first web plate along the length direction of the first web plate; or/and a plurality of lightening holes are formed in the second web plate along the length direction of the second web plate. The design of lightening hole can satisfy the weight of further guide rail assembly that guide rail assembly strength of use required.

The wear resistance of the second upper wing plate or/and the second upper wing plate can be improved, the service life of the second upper wing plate or/and the second upper wing plate is prolonged, and the service life of the guide rail assembly can be prolonged.

Optionally, an upper wear-resisting plate is arranged on the top surface of the second upper wing plate; or/and a lower wear-resisting plate is arranged on the bottom surface of the second lower wing plate. When the coaster was installed on the guide rail assembly of this design, coaster direct action was last antifriction plate or/and lower antifriction plate, can improve the wearability of guide rail assembly, improved life.

A pulley guide rail assembly structure comprises the guide rail assembly and a pulley, wherein roller discs arranged on two sides of the bottom of the pulley are respectively clamped and embedded on 2 second guide rails in a sliding manner;

the roller on the upper side of the roller disc is attached to the top surface of the second upper wing plate, and the roller on the lower side of the roller disc is attached to the bottom surface of the second lower wing plate, so that the pulley can slide on the second guide rail along the guide rail assembly;

when the top surface of the upper wing plate II is provided with an upper wear-resisting plate, and the bottom surface of the lower wing plate II is provided with a lower wear-resisting plate, the roller on the upper side of the roller disc is attached to the top surface of the upper wear-resisting plate, and the roller on the lower side of the roller disc is attached to the bottom surface of the lower wear-resisting plate.

By adopting the pulley guide rail assembly structure, the pulley is arranged on the guide rail assembly, the pulley directly acts on the second guide rail (the pulley does not directly act on the first guide rail), and specifically, the roller disc of the pulley directly acts on the second upper wing plate (when the upper wear-resistant plate is arranged, the upper wear-resistant plate is acted on) and the second lower wing plate (when the lower wear-resistant plate is arranged, the lower wear-resistant plate is acted on) of the second guide rail. So that the pulley can slide on the second guide rail along the guide rail assembly. The guide rail assembly can meet the requirement on use strength, saves materials, reduces the manufacturing cost and lightens the weight of the guide rail assembly; the assembly structure of the trolley rail of the invention formed by using the rail assembly of the invention also has the above-mentioned advantageous effects.

Furthermore, a rack is arranged on the top surface of the first upper wing plate of the guide rail assembly; the pulley is provided with a gear meshed with the rack and a driving device for driving the gear to rotate, and when the driving device drives the gear to rotate, the pulley can reciprocate along the guide rail assembly under the transmission action of the gear and the rack. The invention further designs a driving mechanism which can lead the pulley to do reciprocating motion along the guide rail assembly, and adopts a structural form of gear and rack transmission, so that the reciprocating motion of the pulley is more stable and reliable.
