Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, and particularly relates to a protection device for a drilling winch. Background Technique

[0002] The drilling winch is an important equipment in oil drilling, and its background technique mainly covers the following aspects:

[0003] In the early oil drilling operations, the methods of lifting and lowering the drill string were relatively simple and primitive, with low efficiency and poor safety. With the development of the oil industry, the requirements for drilling depth and speed have been continuously increasing, and the traditional lifting devices have gradually been unable to meet the needs.

[0004] The progress of mechanical technology has continuously optimized the structure and performance of the winch, developing from simple manual operation to complex electric and hydraulic drive systems, improving the control accuracy and reliability of the winch.

[0005] The development of materials science has also brought about a revolution for the drilling winch. The application of high-strength, wear-resistant, and corrosion-resistant materials has extended the service life of the winch components.

[0006] The introduction of automation and intelligent technologies enables the drilling winch to achieve functions such as automatic speed regulation, overload protection, and fault diagnosis, improving the efficiency and safety of drilling operations.

[0007] The drilling winch has the following characteristics and components:

[0008] Main characteristics:

[0009] Lifting and towing functions: It can wind or unwind ropes, chains, etc. through the rotation of the drum, thereby realizing the lifting, lowering, or horizontal towing of heavy objects;

[0010] Multiple application scenarios: Widely used in mines, construction, ports, ships, water conservancy projects and other fields for lifting goods, towing vehicles, lifting personnel, etc.;

[0011] Different drive methods: It can be powered by electric motors, internal combustion engines, hydraulic motors, etc.;

[0012] Components:

[0013] Drum: Used for winding ropes or chains, and is the key component to realize lifting and towing;

[0014] Drive device for winding: Such as motors, engines or hydraulic systems, which provide power for the rotation of the drum;

[0015] Braking device: Ensures that the winch can hold the position of the heavy object when it stops running, preventing accidental sliding or falling and ensuring safety;

[0018] During the drilling process, a winch is required to cooperate. The drums of traditional winches are all in an exposed state. When foreign objects from the outside fall on the surface of the rotating drum, the drum will wind up the foreign objects and the rope together. When the rope is wound up, it will be very tight, and the rope will tightly wrap around the foreign objects, resulting in damage to the part of the rope in contact with the foreign objects and reducing the safety of using the drilling winch.

[0041] As a technical optimization solution of the present utility model, by providing the heat dissipation opening 9, it can dissipate the heat inside the shielding protective cover 6 for preventing foreign impurities from falling, avoiding the heat generated by the friction between the drum 3 and the rope body from not being dissipated, and improving the use safety of the drum 3.

[0042] Reference Figure 1 , a handle 10 is fixedly connected to the left side of the top of the shielding protective cover 6 for preventing foreign impurities from falling, and the handle 10 is located at the top of the metal frame 1 for a drilling winch.

[0043] As a technical optimization solution of the present utility model, by providing the handle 10, it can facilitate the user to pull the shielding protective cover 6 for preventing foreign impurities from falling to move, avoiding that it is difficult to be caught when the shielding protective cover 6 for preventing foreign impurities from falling needs to be moved, resulting in the shielding protective cover 6 for preventing foreign impurities from falling being not easily pulled, and improving the control efficiency of the shielding protective cover 6 for preventing foreign impurities from falling.

[0044] Reference Figure 4 , reinforcing blocks 11 are fixedly connected to the front side and the rear side of the bottom of the handle 10, and the bottom of the reinforcing block 11 is fixedly connected to the top of the shielding protective cover 6 for preventing foreign impurities from falling.

[0050] The working principle and usage process of the present utility model: When in use, in the figure, the drum 3 is in the state of being shielded and protected by the shielding protective cover 6 for preventing foreign impurities from falling. When foreign objects in the outside world float down, they will be blocked by the shielding protective cover 6 for preventing foreign impurities from falling, and the falling foreign objects cannot contact the drum 3. The rope body wound by the drum 3 is protected. When it is necessary to repair the drum 3, push the shielding protective cover 6 for preventing foreign impurities from falling to move to the left. The shielding protective cover 6 for preventing foreign impurities from falling drives the horizontal moving block 5 to slide to the left on the surface of the translational sliding rod 4. The shielding protective cover 6 for preventing foreign impurities from falling drives the working port 7 to move to the left. When the shielding protective cover 6 for preventing foreign impurities from falling moves to the extreme left position, the drum 3 inside the metal frame 1 for the drawworks is exposed to the air, thus having the advantage of good protection effect.

[0051] In summary: For the protective device for the drawworks, through the combined use of the metal frame 1 for the drawworks, the winding drive device 2, the drum 3, the translational sliding rod 4, the horizontal moving block 5, the shielding protective cover 6 for preventing foreign impurities from falling, and the working port 7, it solves the problem that the drums of the drawworks are all in an exposed state. When foreign objects in the outside world fall on the surface of the rotating drum, the drum will wind up the foreign objects and the rope body together. Since the rope body is very tight when being wound up, the rope body will tightly wrap the foreign objects, resulting in damage to the part of the rope body in contact with the foreign objects and reducing the safety of using the drawworks.
