Description

Drill pipe repair automatic conveying production line

technical field

The utility model relates to conveying equipment, in particular to an automatic conveying production line for drill pipe repair.

Background technique

In the past, the pipe company had nearly 10,000 drill pipes, drill collars, and casing threads to be repaired each year, which were mainly repaired by the pipe thread lathe of the lathe crew in the well control workshop. The repair process requires the close cooperation between the driver and the lathe operator, and the manual loading and unloading of a single piece, that is, the driving hangs the drill pipe through the hole in the wall, and transports the head of the drill pipe to the indoor lathe chuck, and the chuck clamps the drill pipe Finally, the drill pipe thread is repaired. After the thread repair is completed, the crane lifts the drill pipe again, lifts the drill pipe out of the wall hole, and puts it on the material rack. The whole process is labor-intensive and inefficient, resulting in a serious lag in drilling tool repair work.

Utility model content

The technical problem to be solved by the utility model is to provide an automatic conveying production line for drill pipe repair in view of the above-mentioned prior art, which reduces a lot of auxiliary time, greatly improves production efficiency, reduces labor intensity of workers, and is convenient, safe and reliable to operate.

The technical scheme adopted by the utility model to solve the above problems is: an automatic conveying production line for drill pipe repair, which includes a conveying device and a floating rotating device, as well as a feeding rack and a feeding rack. It is lifted under the action, so that the drill pipe on the loading rack is automatically rolled into the conveying roller, and the conveying roller is driven by the motor to send the drill pipe to the position of the lathe, and the floating cylinder on the floating rotating device lifts the rotating idler roller , the drill pipe is separated from the conveying roller and placed on the rotating idler roller to complete the repair, and the repaired drill pipe is arranged and collected on the unloading rack.

An adjusting screw is arranged between the conveying frame on the conveying device and the conveying lifting plate, and the conveying roller is fixed on the conveying lifting plate, and the height of the drill pipe on the conveying roller is adjusted by adjusting the threaded rod, so that the drill pipe enters the lathe smoothly Fix location.

A floating adjustment screw is arranged between the floating frame and the floating platform on the floating rotating device, and the rotating rollers are fixedly connected in pairs on the floating platform, and the center line of the drill pipe of different specifications is adjusted to the lathe through the adjustment of the floating adjustment screw. The centerline remains the same.

Compared with the prior art, the utility model has the advantages of:

1. The single feeding is changed to bundled feeding, and the loading and unloading is button operation, and the automatic operation according to the program reduces the running frequency of the driving and the waiting time for feeding, and reduces a lot of auxiliary time. The production efficiency is doubled. For example, the workload of repairing 13 to 15 heads in one shift is now completed in half a shift. And greatly reduce the labor intensity of drivers and lifters.

2. Easy to operate, safe and reliable.

3. Reduce the impact of climate on restoration work.

4. Using polyurethane rollers, the noise is greatly reduced, and the shock is cushioned to protect the equipment.

Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, an automatic conveying production line for drill pipe repair in this embodiment includes a plurality of conveying devices 1 and floating rotating devices 2 located in a straight line, as well as a feeding rack 3 and a feeding rack 4 , the conveying device 1 constitutes the basis for transporting the drill pipe (drill collar), and is responsible for sending the drill pipe (drill collar) into the turning station. During the turning process, the floating rotating device 2 plays a role in supporting the drill pipe (drill collar) Thereby repairing, the loading rack 3 and the unloading rack 4 are located on both sides of the conveying device 1 respectively, and the end of the feeding rack 3 close to the conveying device 1 is lower than the other end, forming a falling angle of inclination, which is convenient for waiting. The repaired drill pipes fall onto the conveying device 1, and one end of the unloading frame 4 close to the conveying device 1 is higher than the other end, so that the repaired drill pipes leave the conveying device 1, so that the subsequent drill pipes to be repaired can work continuously.

As shown in Figure 3, the conveying device 1 includes a conveying frame 1.1, a conveying lifting plate 1.2 and a conveying roller 1.3, and the conveying frame 1.1 and the conveying lifting plate 1.2 are connected by a pair of vertical guide rails, and are installed on the conveying frame 1.1. There is a lifting cylinder 1.4 connected to the conveying lifting plate 1.2, and the conveying roller 1.3 is fixedly connected to the conveying lifting plate 1.2, and is driven by a motor 1.5. At the same time, a conveying adjustment screw 1.6 is set between the conveying frame 1.1 and the conveying lifting plate 1.2 , by adjusting the screw rod 1.6 to adjust the position of the conveying center line, so that the center line of the drill pipe of different specifications is consistent with the center line of the lathe.

As shown in Figure 4, the floating rotating device 2 includes a floating frame 2.1, a floating platform 2.2 and a rotating roller 2.3, the floating frame 2.1 and the floating platform 2.2 are connected by a pair of vertical guide rails, and installed on the floating frame 2.1 There is a floating cylinder 2.4 connected to the floating platform 2.2, and the rotating idler rollers 2.3 are fixedly connected to the floating platform 2.2 in pairs, and the axis of the rotating idler rollers 2.3 is parallel to the drill pipe, and is set between the floating frame 2.1 and the floating platform 2.2 There is a floating adjustment screw 2.5, and after the rotating idler 2.3 lifts the drill rod, the centerline of the drill rods of different specifications is kept consistent with the centerline of the lathe through the adjustment of the floating adjustment screw 2.5.

Working process: When feeding, the conveying roller rises, lifts the drill pipe at the lower end of the loading rack 3 and rolls it into the V-shaped conveying roller, turns on the motor, and conveys the drill pipe to the indoor lathe position. The screw rod 1.6 makes the center line of the drill pipe consistent with the center line of the lathe, and then the rotating idler roller 2.3 is raised by the floating cylinder 2.4, so that the drill rod is separated from the conveying roller and falls on the rotating idler roller, and the screw rod 2.5 is adjusted by floating To adjust the position of the drill rod and the lathe. After the repair of the drill pipe is completed, the rotating idler rolls down under the action of the floating cylinder, and the conveying roller catches the drill pipe. The inside is high and the outside is low, so the drill pipe rolls off the conveyor.

In addition to the above-mentioned embodiments, the utility model also includes other implementation modes, and any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the claims of the utility model.
