Embodiment Construction
[0017] The present invention will be further described below in conjunction with accompanying drawing:
[0018] As shown in the accompanying drawings, the top drive slide-in folding guide rail plate includes a transport frame guide rail plate, a guide rail plate 2 and a wire rope tightening guide rail plate 1. Install the trolley 3, the installation trolley 3 is welded into an H shape by the vertical plate and the rib plate, the rollers clamped on the slideway of the guide rail plate 2 are connected in the vertical plate, the upper end of the installation trolley 3 has a toggle plate 4, and the toggle plate 4 There is a chamfer at the upper end, and the toggle plate 4 plays the role of pushing the dead bolt 10, and the chamfer plays a guiding role. Wire rope tightening guide rail plate 1 top outside has the limiter plate 5 that stops installation dolly 3 to move up, and limiter plate 5 plays the effect of limiting installation dolly 3 and top drive to break away from. The inn...

The invention relates to a top driving slippery insert type folding guide rail plate, which mainly solves the problems that the traditional guide rail plate of a top driving drilling machine has low loading and unloading efficiency and needs aerial working. The top driving slippery insert type folding guide rail plate is characterized in that a sliding rail of a wire rope tensioning guide rail plate (1) is connected with an installation car (3) capable of sliding up and down; an inner plate (6) of the wire rope tensioning guide rail plate (1) is inserted into an axial opening of a sliding plate (7); a bolt (10) matched with racks (9) and the sliding plate (7) is arranged on the sliding plate (7); the upper ends of the guide rail plate (2) and bottom guide rails (16) are respectively provided with a fixing joint (11) which is hinged with sliding joints (12) at the lower ends of the primary four sections of guide rail plate (2) and a wire rope tensioning guide rail plate (1) through hinging blocks (13); and a lifting hook (14) is arranged at the lower end of a tail guide rail plate (2) which is internally connected with a lower fixed pulley (15). The top driving slippery insert type folding guide rail plate not only has high loading and unloading rate, but also does not need aerial working.
Description
Technical field: [0001] The invention relates to a guide rail plate used for a top drive drilling rig, in particular to a top drive slide-insert folding guide rail plate. Background technique: [0002] With the exploration and development of oil and gas, the demand for top drive drilling rigs is becoming more and more urgent. The top drive device directly drives the drilling tool with power from the top of the derrick for rotary drilling, which changes the traditional rotary drilling method and can complete various drilling such as circulating drilling fluid, erecting, making up and breaking out, and back reaming. operating drilling rig. In order to prevent the top drive from rotating itself, it is necessary to slide the top drive up and down on the guide rail plate, which is vertically installed between the upper part of the derrick and the drill floor. The guide rail plate is composed of 5-7 joints, and each joint is 5-6 rice. The main function of the guide rail is to b...
