Problems solved by technology

[0005] In the actual manufacturing process, the assembly process between the trolley assembly and the guide rail assembly is relatively difficult
After in-depth research, the applicant found that since the pulley assembly is usually designed as an integrated structure, and the motor has braking and locking functions, if the motor is not powered on, the pulley cannot walk along the guide rail assembly, and assembly operations cannot be performed at this time
When the motor is energized, the trolley assembly is fed from the end of the guide rail assembly to the guide rail assembly, so that the gear and the rack are meshed. At the same time, the sliding clips of the roller discs on both sides of the bottom of the trolley need to be embedded in the The two sides of the guide rail assembly, which makes the assembly process very difficult

Embodiment 1

[0057] like Figure 3 to Figure 11 As shown, a method for assembling a pulley guide rail of the present embodiment includes the following steps:

[0058] S1: Place the pulley 5 on the top of the guide rail assembly, and the gear 53 assembled at the bottom of the pulley 5 meshes with the rack 4 on the top of the guide rail assembly;

[0059] S2: Sliding the roller disc unit 51 into the two sides of the guide rail assembly;

[0060] S3: On the guide rail assembly, the pulley 5 and the roller disc unit 51 are connected through the connecting piece 50 to form an integral structure.

[0061] When using the pulley guide rail assembly method of the present invention, it is obvious that the pulley assembly at least includes the pulley 5 and the roller disc unit 51, and the two are a split structure (a structure independent of each other); for the guide rail assembly, the Both sides can be matched with the roller disc unit 51, so that the roller disc unit 51 can be slidably inserted ...

Embodiment 2

[0071] like Figure 3 to Figure 11 As shown, a pulley guide rail assembly structure in this embodiment includes a pulley assembly and a guide rail assembly with a rack 4 at the top, the pulley assembly includes a pulley 5 and a roller disc unit 51, and the pulley 5 and the The roller disc unit 51 can be connected by the connecting piece 50 to form an integral structure; wherein,

[0072] The pulley 5 is placed on the top of the guide rail assembly, and the gear 53 assembled at the bottom of the pulley is engaged with the rack 4 on the top of the guide rail assembly;

[0073] The roller disc unit 51 is slidably inserted into both sides of the guide rail assembly;

[0074] The pulley 5 placed on the top of the guide rail assembly and the roller disc unit 51 embedded in the two sides of the guide rail assembly are connected by the connecting member 50 to form an integral structure.

[0075] When the pulley guide rail assembly structure of the present invention is adopted, thank...

Embodiment 3

[0081] In order to facilitate understanding of the present invention, the present invention specifically introduces a specific design of a guide rail assembly through the third embodiment.

[0082] like Figure 9 to Figure 11 As shown, a guide rail assembly in this embodiment includes guide rails 1 and 2; With the lower wing plate 1 12, the guide rail 2 includes a web plate 23, an upper wing plate 21 and a lower wing plate 2 22 arranged at the upper and lower ends of the web plate 2; along the length direction of the guide rail 1, 2 The upper wings 21 of each of the second guide rails 2 are respectively connected to both sides of the upper wings 11 of the guide rail 1 , and a rack 4 is provided on the top surface of the upper wings 11 . The guide rail 1 mainly plays the role of connecting two guide rails 2 , so that the guide rail assembly forms an integral structural form, and the guide rail 2 is used for direct load bearing.

[0083] preferably, as Figure 10 As shown, th...

Abstract

The invention discloses an assembly method and structure of a pulley guide rail and a power catwalk, belonging to the technical field of power catwalks. A method for assembling a pulley guide rail of the present invention includes the following steps: S1: place the pulley on the top of the guide rail assembly, and the gears assembled at the bottom of the pulley engage with the rack on the top of the guide rail assembly; S2: slide the roller disc unit The clips are embedded on both sides of the guide rail assembly; S3: On the guide rail assembly, the pulley and the roller disc unit are connected by connecting pieces to form an integral structure. When the invention is adopted, the pulley and the roller disc unit are mutually independent structures, and there is no mutual restriction between the installation action of the pulley and the installation action of the roller disc unit, so that the action process of the pulley being installed on the guide rail assembly and the The action process of installing the roller disc unit on the guide rail assembly becomes simple and easy, which reduces the difficulty of the assembly process of the pulley guide rail, improves the assembly efficiency, and achieves the purpose of assembly.

Description

technical field [0001] The invention relates to an assembly method and structure of a pulley guide rail and a power catwalk, belonging to the technical field of power catwalks. 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 outriggers on both sides of the power catwalk (the outriggers can also be called bent frames) to the drilling floor, and can also transport the drilling tools to the drilling floor. The drilling tools on the table are transported and arranged to the legs on both sides of the power catwalk; for example, Chinese patent CN201520866530.4, a power catwalk; Chinese patent CN201420525189.1, a cylinder-lifting land power catwalk; Chinese patent CN201420660266.4, a power catwalk for a rack and pinion drilling rig. [0003] The main drive system of the power catwalk is a driving system used to lift and lower the power c...
