Description

Technical Field

[0001] This utility model belongs to the field of oil well logging tool technology, specifically relating to a hook wrench. Background Technology

[0002] Hook wrenches are essential tools used for assembling and disassembling logging instruments at the wellhead during well logging operations. Traditional hook wrenches have an open structure and suffer from the following drawbacks: Poor compatibility: Logging instruments come in various outer diameters, requiring different sized hook wrenches for different diameter instruments; Risk of injury to personnel: The handle is smooth and lacks anti-slip properties, making it easy for the wrench to slip from the operator's hand during heavy hammering or tightening operations, potentially causing injury; High noise levels: The metallic clanging produces a harsh noise that can cause varying degrees of hearing damage to on-site personnel; High maintenance costs: Partial damage to the hook wrench necessitates complete replacement, resulting in high maintenance costs; High risk of falling into the well: The open design of traditional hook wrenches prevents them from being securely attached to the instrument, making them prone to slipping off and falling into the well, thus increasing the cost of retrieval operations.

[0020] To better understand the purpose, structure, and function of this utility model, a hook wrench of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figure 1 , Figure 2 As shown, it illustrates a hook wrench according to an embodiment of the present invention, including a wrench body 4 and a hook head body 12, and also includes a connector 3. One end of the connector 3 is hinged to the hook head body 12. The wrench body 4 is connected to a fixing structure for fixing the connector 3, and the position of the connector 3 fixed on the wrench body 4 is adjustable.

[0022] The hook wrench of this embodiment includes a connector 3. One end of the connector 3 is hinged to the hook body, and the other end of the connector 3 is fixed to the wrench body 4, so that the overall structure of the connector 3, the wrench body 4 and the hook body is ring-shaped. The position of the connector 3 fixed to the wrench body 4 is adjustable so that the diameter of the ring is adjustable. Thus, the hook wrench of this embodiment can be locked onto instruments of different diameters, thereby solving the problem of the hook wrench slipping off the instrument and falling into the well, and effectively avoiding the expenditure of large retrieval costs.

[0023] In practice, for example, one end of the connector 3 is hinged to the hook head via the connecting pin 10.

[0024] In one embodiment, such as Figure 3 , Figure 4 As shown, the fixing structure includes a fixing frame 9 fixed on the wrench body 4. The fixing frame 9 has a groove 8 for the connector 3 to pass through. An adjusting member 7 is connected to the side wall of the fixing frame 9 away from the wrench body 4. The length of the adjusting member 7 extending into the groove 8 is adjustable so that the adjusting member 7 abuts against the connector 3 to fix the connector 3 in the groove 8, and so that the adjusting member 7 moves away from the connector 3 to adjust the position of the connector 3 fixed on the wrench body 4.

[0025] In this embodiment, the connector 3 is fixed in the groove 8 of the fixing frame 9 by the adjusting member 7. Specifically, the adjusting member 7 is connected to the fixing frame 9, and the length of the adjusting member 7 extending into the fixing frame 9 is adjustable. Therefore, by changing the length of the adjusting member 7 extending into the fixing frame 9, on the one hand, the adjusting member 7 can abut against the connector 3, thereby fixing the connector 3 in the groove 8; on the other hand, the adjusting member 7 can be moved away from the connector 3 to adjust the position of the connector 3 fixed on the wrench body 4, thereby adapting to instruments of different diameters.

[0026] In practice, the adjusting component 7 is a locking screw, which is threadedly connected to the fixing bracket 9. Therefore, by adjusting the locking screw, the length of the locking screw extending into the fixing bracket 9 can be adjusted. On the one hand, the locking screw can abut against the connecting component 3, thereby fixing the connecting component 3 in the groove 8. On the other hand, the locking screw can be removed from the connecting component 3 to adjust the position of the connecting component 3 fixed on the wrench body 4.

[0027] Among them, connector 3 is a chain, and a lead rod is fixedly connected to the end of the chain away from the hook head body. A tapered head is provided at the end of the locking screw that contacts the chain.

[0028] In this embodiment, the connecting component 3 is a chain. The chain has good toughness, which allows it to be better locked onto the instrument. The chain is compatible with more than ten different outer diameter series of instruments, such as the 3700 and 5700 models, pressure sampling instruments, NMR instruments, and rotating well core sampling instruments of various diameters. It achieves multi-functionality and overcomes the problem of resource waste and increased costs caused by requiring corresponding sizes for each instrument, thereby improving operational flexibility and reducing dependence on multiple different tools. Furthermore, the tapered head of the locking screw allows it to extend into the chain, thus better securing the chain; the guide rod allows the chain to pass through the groove 8 more smoothly and conveniently.

[0029] In practice, the locking screws, fixing brackets 9, and chains are made of materials that are corrosion-resistant and impact-resistant.

[0030] In one embodiment, a handle 11 is threadedly connected to the end of the wrench body 4 away from the hook. A handle retaining pin 2 is also connected between the wrench body 4 and the handle 11.

[0031] The handle fixing pin 2 in this embodiment can prevent the handle from loosening when it is tightly locked and struck. The design of the wrench body 4 and the handle allows the wrench body 4 or the handle to be replaced individually, thereby reducing maintenance costs and effectively achieving cost reduction and efficiency improvement.

[0032] The handle features knurling 1. Knurling 1 increases friction, reducing the risk of accidents caused by existing hook wrenches flying out of the hand and injuring people.

[0033] The handle is filled with sound-absorbing foam. This foam absorbs noise generated when metal strikes the front of the handle, effectively protecting the operator's hearing.

[0034] The wrench body 4 and the hook head are hinged together by the hook head fixing pin 6, and the hook head is threaded with a hook head screw 5.

[0035] In practical use, place the hook wrench at the instrument connection buckle, and after the chain wraps around the instrument once, pass it through the groove 8 of the fixing frame 9 via the lead rod. Tighten the chain and tighten the locking screw. At this time, the conical head of the locking screw squeezes the chain link. Under the action of the conical surface, the chain abuts against the fixing frame 9. The deeper the locking screw is tightened, the more firmly the chain is fixed, thus achieving the purpose of binding the chain to the instrument.

[0036] The hook wrench in this embodiment solves the problem of hook wrenches slipping off the instrument and falling into the well, effectively avoiding large retrieval costs; it increases friction, reducing the occurrence of safety accidents caused by existing hook wrenches flying out of the hand and injuring people; it can absorb the noise generated when metal strikes the front end of the handle, thus effectively protecting the operator's hearing; and it can be replaced individually, thereby reducing maintenance costs and effectively achieving cost reduction and efficiency improvement.
