Description

Technical Field

[0001] The utility model belongs to the technical field of top drive guide rails, in particular to a foldable top drive guide rail. Background Art

[0002] With the development of oil and gas drilling technology, the demand for traditional drilling rigs to be equipped with top drives is becoming more and more urgent. Guide rails are an indispensable component of top drive equipment. At present, in top drive drilling equipment at home and abroad, the installation of guide rails mainly relies on workers to connect the guide rails by inserting the pins at high altitude. The guide rails need to be suspended at a height of 30m-40m, the pin holes of the guide rails at both ends need to be aligned, and the pins need to be driven into the pin holes. Due to the limitations of working space and environment, it is difficult and time-consuming to insert the pins at high altitude, the labor intensity of the workers is high, and the risk of falling from high altitude is high.

[0003] The existing guide rail structures are all fixed connection structures, which are extremely inconvenient to use and install, and are prone to safety hazards. Therefore, in order to solve the above problems, a foldable top drive guide rail is developed, which is connected between the guide rails by hinges. However, due to the hinges, the guide rails are prone to shaking, and the connection between the guide rails is poor, which easily causes the stability of the equipment to decrease. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a foldable top drive guide rail, which drives the fixed column to move by starting the cylinder, and the fixed column will enter the interior of the fixed sleeve, thereby enhancing the stability of the connection between the first guide rail segment and the second guide rail segment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foldable top drive guide rail, comprising a first guide rail segment, a second guide rail segment and a connecting piece, the first guide rail segment and the second guide rail segment are movably connected through the connecting piece, the surfaces of the first guide rail segment and the second guide rail segment are respectively fixedly connected with guide blocks, a positioning groove is provided at one end of the first guide rail segment corresponding to the position of the second guide rail segment, a circular hole is provided at one end of the second guide rail segment corresponding to the position of the first guide rail segment, a spring is fixedly connected to the inside of the circular hole, a positioning column is fixedly connected to one end of the spring, the positioning column is slidably connected to the inside of the circular hole, a fixing plate is fixedly connected to the surface of the fixing plate, a cylinder is fixedly connected to the surface of the fixing plate, a fixing column is fixedly connected to the end of the cylinder away from the fixing plate, a fixing sleeve is fixedly connected to the surface of the second guide rail segment, and the position of the fixing sleeve corresponds to the position of the fixing column.

[0006] Furthermore, wire grooves are respectively provided inside the first guide rail segment and the second guide rail segment, and steel wire ropes are provided inside the wire grooves.

[0007] Furthermore, one end of the positioning column away from the spring is movably connected to the inside of the positioning groove.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. After the fixed positioning column contacts the surface of the first guide rail segment, it contracts inside the circular hole to squeeze the spring. When the positioning column corresponds to the positioning groove, the positioning column is reset and enters the positioning groove for positioning under the action of spring rebound. The fixed column is driven to move by starting the cylinder, and the fixed column will enter the interior of the fixed sleeve, thereby enhancing the stability of the connection between the first guide rail segment and the second guide rail segment.

[0010] 2. When the wire rope is tightened, the first guide rail segment and the second guide rail segment can be tightened, thereby ensuring the normal use of the guide block. BRIEF DESCRIPTION OF THE DRAWINGS
