Description

Technical Field

[0001] This utility model relates to the field of adapter technology, specifically to an adapter for connecting a traveling block hook and a top drive. Background Technology

[0002] The traveling block hook plays a crucial role in oil drilling and other heavy lifting operations. By connecting the derrick and the traveling block, the traveling block hook enables the lifting and movement of heavy objects. In oil drilling operations, it is responsible for connecting the derrick and the traveling block, allowing the drill string to be lifted and lowered smoothly. The top drive lifting ring connects the hook to the lifting clamp, assisting the lifting clamp and hook in lifting tubing and drill pipe.

[0003] The top drive lifting ring can bear most of the weight, reducing the force on the drill pipe and drill bit, thereby extending their service life. The existing connection between the derrick and the top drive is through the derrick traveling block hook directly connecting to the top drive lifting ring. This can lead to problems such as the hook and lifting ring not connecting properly, resulting in a mismatch and affecting drilling efficiency and safety. Utility Model Content

[0004] The purpose of this utility model is to provide a traveling block hook and top drive connection adapter to solve the problem mentioned in the background art that the existing connection between the derrick and the top drive is directly connected to the top drive lifting ring through the traveling block hook, which results in the hook and lifting ring not being able to connect properly, and the two being mismatched, affecting drilling operation efficiency and safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a traveling block hook and top drive connection adapter, comprising an adapter assembly:

[0006] The adapter assembly has a pin baffle on its surface, a large hook pin inserted inside the adapter assembly, hexagonal head bolts inserted inside both sides of the pin baffle, elastic washers fitted on the outer wall of the hexagonal head bolts, flat washers on the surface of the elastic washers, and a support plate on the inner surface of the adapter assembly.

[0007] Preferably, the adapter assembly is configured as two sets, and the two sets are supported by a support plate, and the pin baffle is used to limit the axial displacement of the hook pin.

[0008] Preferably, the pin baffle has through holes on both sides of its surface, and the adapter assembly has threaded holes on both sides of its surface. One end of the hexagonal head bolt passes through the through hole in the pin baffle and is rotatably connected to the threaded hole in the adapter assembly.

[0009] Preferably, the elastic washer and the flat washer are fitted onto the outer surface of the hexagonal head bolt, and the elastic washer and the flat washer fill the space between the pin baffle and the hexagonal head bolt for cushioning.

[0010] Preferably, the support plate is connected to two fixed rods on both sides, one end of the fixed rod is connected to a threaded rod, one end of the threaded rod is provided with a limit ring, the outer surface of the threaded rod is rotatably connected to a threaded collar, and one end of the threaded collar is provided with a rubber gasket.

[0011] Preferably, the adapter assembly has movable slots on both sides of its surface, and the fixing rod is inserted into the movable slots of the adapter assembly and is movably connected to the adapter assembly.

[0012] Preferably, the threaded rod and the threaded collar are rotatably connected by threads, and the rubber gasket is filled between the adapter assembly and the threaded collar for cushioning.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Two adapter assemblies are supported by a support plate. The large hook pin at the upper end of the adapter assembly connects to the derrick traveling block hook, while the lower end of the adapter assembly connects to the drilling rig top drive lifting ring. Elastic washers and flat washers are then fitted onto the outer surface of the hexagonal head bolt. One end of the hexagonal head bolt is then passed through the through hole in the pin baffle and rotated into the threaded hole in the adapter assembly, limiting the pin baffle. Elastic and flat washers buffer the pin baffle and hexagonal head bolt, ensuring flexible contact between them. The pin baffle restricts the axial displacement of the large hook pin, thus connecting the derrick traveling block hook to the drilling rig top drive. This solves the problem of direct connection failure or mismatch between the derrick traveling block hook and the drilling rig top drive, ensuring the timeliness and safety of the drilling process.

[0015] 2. By rotating the threaded collar to move it on the outer surface of the threaded rod, and using the limiting ring to limit the movement of the threaded collar, the threaded collar will not disengage from the threaded rod. After the distance between the adapter assembly and the threaded collar increases, the angle of the threaded rod is adjusted, causing the fixed rod to drive the support plate to adjust its angle. After the adjustment is completed, the threaded collar is rotated in the opposite direction, causing the rubber gasket to fill the space between the adapter assembly and the threaded collar for cushioning. The threaded collar is used to lock the threaded rod, thereby achieving the angle adjustment of the support plate. The support point is adjusted by adjusting the angle of the support plate.

[0023] Please see Figure 1-5 One embodiment provided by this utility model:

[0024] A travel car hook and top drive connection adapter, including adapter assembly 11:

[0025] The adapter assembly 11 has a pin baffle 12 on its surface and a large hook pin 13 inserted inside. Hexagonal head bolts 14 are inserted inside both sides of the pin baffle 12. Elastic washers 15 are sleeved on the outer wall of the hexagonal head bolts 14. Flat washers 16 are provided on the surface of the elastic washers 15. A support plate 17 is provided on the inner surface of the adapter assembly 11. The internal material of the adapter assembly 11 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application. Therefore, no further details are provided.

[0026] Furthermore, the adapter assembly 11 is configured as two sets, and the two sets are supported by the support plate 17. The pin baffle 12 is used to limit the axial displacement of the hook pin 13, so as to limit the axial displacement of the hook pin 13 by the pin baffle 12, maintain positioning accuracy, and thus ensure the normal operation of the equipment.

[0027] Furthermore, through holes are provided on both sides of the surface of the pin baffle 12, and threaded holes are provided on both sides of the surface of the adapter assembly 11. One end of the hexagonal head bolt 14 passes through the through hole of the pin baffle 12 and is rotatably connected to the inside of the threaded hole of the adapter assembly 11, so as to connect and fix the adapter assembly 11 and the pin baffle 12 by means of the hexagonal head bolt 14.

[0028] Furthermore, the elastic washer 15 and the flat washer 16 are fitted onto the outer surface of the hexagonal head bolt 14. The elastic washer 15 and the flat washer 16 fill the space between the pin baffle 12 and the hexagonal head bolt 14 to provide cushioning, thereby achieving flexible contact between the pin baffle 12 and the hexagonal head bolt 14 through the elastic washer 15 and the flat washer 16.

[0029] Furthermore, the support plate 17 is connected to two fixed rods 18 on both sides, and one end of the fixed rod 18 is connected to a threaded rod 19. A limit ring 20 is provided on the surface of one end of the threaded rod 19, and a threaded collar 21 is rotatably connected to the outer surface of the threaded rod 19. A rubber gasket 22 is provided on the surface of one end of the threaded collar 21 to realize the angle adjustment of the support plate 17.

[0030] Furthermore, movable slots are provided on both sides of the surface of the adapter assembly 11, and the fixing rod 18 is inserted into the movable slots of the adapter assembly 11 and is movably connected to the adapter assembly 11, so as to position the fixing rod 18 through the movable slots of the adapter assembly 11.

[0031] Furthermore, the threaded rod 19 and the threaded collar 21 are rotatably connected by threads, and the rubber gasket 22 is filled between the adapter assembly 11 and the threaded collar 21 for buffering, so as to achieve flexible contact between the adapter assembly 11 and the threaded collar 21 through the rubber gasket 22.

[0032] Working principle: When the adapter connecting the traveling block hook and the top drive is used, the two adapter assemblies 11 are supported by the support plate 17. The traveling block hook is connected to the derrick using the hook pin 13 set at the upper end of the adapter assembly 11, while the lower end of the adapter assembly 11 is connected to the top drive lifting ring of the drilling rig. Then, the elastic washer 15 and the flat washer 16 are fitted onto the outer surface of the hexagonal head bolt 14. One end of the hexagonal head bolt 14 is then rotated through the through hole of the pin baffle 12 and connected to the threaded hole of the adapter assembly 11 to limit the pin baffle 12. The elastic washer 15 and the flat washer 16 buffer the pin baffle 12 and the hexagonal head bolt 14 to make flexible contact between the two. The pin baffle 12 restricts the axial displacement of the hook pin 13, thereby realizing the connection between the derrick traveling block hook and the top drive of the drilling rig.

[0033] When adjusting the adapter connecting the travel car hook and the top drive, the threaded collar 21 is rotated to move on the outer surface of the threaded rod 19, and the movement of the threaded collar 21 is limited by the limiting ring 20 to prevent the threaded collar 21 from disengaging from the threaded rod 19. After the distance between the adapter assembly 11 and the threaded collar 21 is increased, the angle of the threaded rod 19 is adjusted, causing the fixed rod 18 to drive the support plate 17 to adjust its angle. After the adjustment is completed, the threaded collar 21 is rotated in the opposite direction, causing the rubber gasket 22 to fill the space between the adapter assembly 11 and the threaded collar 21 for buffering. The threaded collar 21 is used to lock the threaded rod 19, thereby achieving the angle adjustment of the support plate 17. The support point is adjusted by adjusting the angle of the support plate 17.
