Problems solved by technology

[0002] The rope rewinding machine is a special equipment used to complete the collection and release of the oil drilling wire rope. At present, the brake mechanism of the large rope drum of the rope rewinding machine includes two types. One is the manual handle brake method. The same length as the large rope drum, and the labor intensity of the workers is high; the other is that the small gear driven by the hydraulic motor meshes with the large gear on the drum. This method is a hard brake, which is easy to cause broken teeth of the small gear and damage to the hydraulic motor.

Embodiment 1

[0018] The automatic braking type rope rewinding machine includes a frame 1, a transmission system, a small rope drum assembly 2, a large rope drum 12 and a main shaft 15, and the transmission system includes an oil tank 3, an oil pump 4, a hydraulic motor 10, a small gear 11 and a large gear 8 , bull gear 8 on bull gear 8 is equipped with shift fork 9, and shift fork 9 can be inserted in the wheel arc of big rope drum 12 after shift fork 9 stretches out and drives big rope drum 12 to rotate.

[0019] One end of the main shaft 15 is fixed in the support shaft 5 through the positioning bearing 7, the support shaft 5 is fixed on the frame 1, the upper end of the support shaft 5 is open, the main shaft end fixed positioning block 6 is arranged in the support shaft 5, and the main shaft end fixed positioning block 6 Positioning bearing 7 is arranged inside, and one end of main shaft 15 is fixed in positioning bearing 7, and the other end of main shaft 15 passes through support bear...

Embodiment 2

[0023] The difference between embodiment 2 and embodiment 1 is the position of the transmission disc 13 and the braking device, such as image 3 As shown, the cross section of a part of the main shaft 15 near the braking device side is a regular hexagon and has six rows of positioning holes 25, the inner wall of the transmission disc 13 is a regular hexagon, and the transmission disc 13 is provided with pin holes 31. 13 can be sleeved on the main shaft 15 and be fixed on the main shaft 15 with pins, so that the transmission disc 13 can adjust the position according to the length of the large rope drum 12, so as to be suitable for the large rope drums 12 of different lengths. Braking device comprises brake bracket, bearing, brake disc 27, brake band 28, brake transmission mechanism 29 and handbrake mechanism 30, and bearing is fixed on the support, and brake disc 27 and two bearings are fixed on the rotating shaft 17, and brake disc 19 is positioned at two Between the two beari...

Abstract

The invention relates to a drilling tool for an oil field, in particular to an automatic brake type rope winding and unwinding machine. The automatic brake type rope winding and unwinding machine comprises a rack, a transmission system, a small rope roller, a big rope roller and a main shaft. The automatic brake type rope winding and unwinding machine is characterized in that one end of the main shaft is fixed into a supporting shaft through a positioning bearing, and the supporting shaft is fixed to the rack; the main shaft is sleeved with a transmission disc, and the transmission disc is provided with transmission pins; the big rope roller is provided with transmission holes, and the transmission pins can be inserted into the transmission holes; the other end of the main shaft penetrates a supporting bearing, and the supporting bearing is fixed to the rack; and the other end of the main shaft is connected with a rotating shaft, and the rotating shaft is provided with a brake device. The automatic brake type rope winding and unwinding machine is high in automation degree, convenient and fast to operate and good in brake effect; and meanwhile, the brake working intensity of operation staff is lowered, and the personnel safety is protected.

technical field [0001] The invention relates to an oil field drilling tool, in particular to an automatic braking type rope reversing machine. Background technique [0002] The rope rewinding machine is a special equipment used to complete the collection and release of the oil drilling wire rope. At present, the brake mechanism of the large rope drum of the rope rewinding machine includes two types. One is the manual handle brake method. The same length as the large rope drum, and the labor intensity of the workers is high; the other is that the small gear driven by the hydraulic motor meshes with the large gear on the drum. This method is a hard brake, which is likely to cause broken teeth of the small gear and damage to the hydraulic motor. Contents of the invention [0003] The object of the present invention is to provide an automatic braking rope rewinding machine that reduces the labor intensity of workers, is suitable for large rope drums of different diameters and ...
