Description

Technical Field

[0001] The invention relates to the technical field of well repair machine control devices, in particular to a long-term overload-proof, non-stringy oil-electric dual-purpose well repair machine controller. Background Art

[0002] Well repair rigs or well hauling rigs are the most basic and main power source in well repair and underground operation. In view of the current status of well repair rigs in oil fields and the current development trend of well repair rigs, we have designed a dual-purpose oil-electric well repair rig without a guy rope in the spirit of safety, high efficiency, energy saving and environmental protection. The comprehensive performance index is higher than that of traditional drive systems. The system has the characteristics of large starting torque, small starting current, high system efficiency and good energy saving effect. The system power can be set according to the capacity of the well site transformer to ensure the safety of the power grid. When the well site power supply cannot meet the needs of electric operation, it can be switched to mechanical power, and the oil-electric system conversion can be completed with just one action. The existing well repair rig controller does not have an overload protection device. Well repair rigs are prone to overload in actual use. If the wire rope is overloaded for a long time and the overload is too heavy, the wire rope will break. In severe cases, the wire rope will break, which will cause the traveling block hook to fall, causing immeasurable losses, not only delaying the construction period, but also easily causing accidents and injuring the on-site staff.

[0015] 2. With the buffer device, when the workover rig is overloaded, the load on the wire rope is overloaded, and the wire rope pulls the drum and winch to move to the right. At the same time, the winch drives the slide plate to move to the right to squeeze the elastic plate, thereby slowing down the speed of the winch moving to the right. At the same time, the buffer device gives the winch a leftward pulling force, so that the winch moves slowly to the right to prevent damage to the winch.

[0016] 3. Utilizing the alarm device, when the workover rig is overloaded, the winch slides to the right, driving the nylon rope to move to the right, so that the positioning rod is moved out of the positioning hole, and the positioning rod releases the fixation to the movable rod. Under the elastic force of the reset spring, the movable rod quickly rotates upward, and the movable rod drives the impact block to rotate quickly, so that the impact block quickly hits the alarm button on the alarm, causing the alarm to sound, thereby reminding the staff that the workover rig is seriously overloaded.

[0030] Working principle: When the well repair machine is operating, the wire rope 41 is turned by the pulley 42, so that the wire rope 41 and the drum 4 are in the same horizontal plane, which is convenient for the drum 4 to retract and release the wire rope 41, and prevents the wire rope 41 from being chaotically bent during winding, thereby effectively protecting the wire rope 41 and reducing the phenomenon of wire rope breakage due to chaotic winding.

[0031] When the workover rig is overloaded, the load on the wire rope 41 is overloaded, the wire rope 41 pulls the drum 4 and the winch 3 to move rightward, the winch 3 drives the slide plate 31 to move rightward, the slide plate 31 slides rightward along the first convex groove 2, and at the same time the slide plate 31 squeezes the elastic plate 32, and the elastic force of the elastic plate 32 slows down the speed of the slide plate 31 moving rightward, thereby slowing down the speed of the winch 3 moving rightward, and at the same time the winch 3 pulls the two chains 6 to move rightward, the chains 6 rotate along the gear plate 61, and at the same time the chains 6 pulls the fixed block 51 to move leftward, and the fixed block 51 drives the convex slider 5 to slide leftward along the second convex groove 21. At the same time, the convex slider 5 squeezes the buffer spring 52. Under the action of the elastic force of the buffer spring 52, the speed of the convex slider 5 moving leftward is slowed down, so that the movement speed of the chain 6 is slowed down, so that the winch 3 moves slowly to the right to prevent the winch 3 from being damaged. At the same time, the winch 3 and the drum 4 move to the right to reduce the tension on the wire rope 41, so as to prevent the wire rope 41 from being broken or ruptured due to overload.

[0032] When the workover rig is overloaded, the winch 3 slides to the right, and at the same time drives the nylon rope 72 to move to the right, and the nylon rope 72 drives the positioning rod 71 to slide to the right, so that the positioning rod 71 moves out of the positioning hole 81, so that the positioning rod 71 loosens the fixation on the movable rod 8, and under the elastic force of the reset spring 83, the movable rod 8 quickly rotates upward, and the movable rod 8 drives the impact block 82 to rotate quickly, so that the impact block 82 quickly knocks the alarm button on the alarm 91, and the alarm 91 sounds an alarm, thereby reminding the staff that the workover rig has been seriously overloaded, and promptly dealing with the overload of the workover rig, thereby protecting the workover rig.
