Description

Technical Field

[0001] The present invention relates to the technical field of drilling tools, in particular to a wire rope joint threading auxiliary device. Background Art

[0002] The rope coring process is an important part of geological core drilling. It mainly uses a ground winch to lower the coring inner tube assembly into the drill bit in the hole through the wire rope, and after the coring is completed, the inner tube assembly and the core inside it are lifted to the surface. In order to ensure the smooth lowering and lifting of the core inner tube assembly, the wire rope needs to be connected and fixed to the inner tube assembly. Considering the production cost, processing difficulty, and the need for regular inspection and cutting of the on-site wire rope according to actual conditions, the wire rope and the inner tube assembly are connected with a flexible joint. When connecting the wire rope on site, it is usually necessary to fold the end of the wire rope slightly and pass it through the wire rope joint hole, and then further thread it. When the folded section of the wire rope is completely inserted into the wire rope joint, it is tightened and fixed. Because the wire rope is hard and thick, it is difficult and time-consuming to manually thread the wire rope on site, and the firmness is not guaranteed.

[0003] Therefore, a wire rope joint threading auxiliary device is needed to facilitate on-site workers to efficiently complete the firm connection between the wire rope and the wire rope joint. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a wire rope joint threading auxiliary device to solve the problems existing in the prior art, so that the wire rope can be passed through the wire rope joint more labor-saving and the connection between the wire rope and the wire rope joint can be more firmly established.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1-Figure 3 As shown, the present invention provides a wire rope joint threading auxiliary device, including a base, a fixing device, a limit plate 2 and an elastic member. A baffle 1 is provided on one side of the base, and the baffle 1 is used to assist in supporting the wire rope 11 and directly support the elastic member. The elastic member directly supports the wire rope. The fixing device is provided on the side of the base away from the baffle 1, and is used to clamp the wire rope 11. The bottom of the limit plate 2 is slidably provided on the base and is arranged opposite to the baffle 1. The limit plate 2 is located between the baffle 1 and the fixing device and can slide toward or away from the baffle 1. The top of the limit plate 2 is used to abut the first end of the wire rope joint 10, and the limit plate 2 is connected to a pushing device, which can drive the limit plate 2 to move through the pushing device, and then drive the wire rope joint 10 to move. The elastic member is used to sleeve A folded end 111 of the wire rope is provided, and one end of the elastic member abuts against the baffle 1, and the other end abuts against the second end of the wire rope joint 10, which is used to support the folded end 111 of the wire rope and provide movement space for the wire rope. There is a certain friction between the elastic member and the baffle 1. The elastic member supports the folded end 111 of the wire rope with the help of friction and provides movement space for the wire rope, and is matched with the limit plate 2 to push the wire rope joint 10 toward the folded end 111 of the wire rope, making it easier for the wire rope to pass through the wire rope joint 10, and the folded end 111 of the wire rope eventually enters the wire rope joint 10 completely, and passes through the wire rope joint 10 as much as possible to reach the small inner diameter section at the right end of the wire rope joint 10, so that the connection between the wire rope and the wire rope joint 10 is more secure.

[0031] In this embodiment, the pushing device includes a first screw 4 and a first nut 5. The first end of the first screw 4 passes through the baffle 1 and is screwed with the first nut 5. The second end of the first screw 4 passes through the limit plate 2. The nut of the first screw 4 can fix the second end of the first screw 4 to the limit plate 2. By adjusting the first nut 5, the limit plate 2 can be driven to move, and then the wire rope joint 10 can be driven to move. Twisting the first nut 5 makes the first screw 4 move toward the baffle 1. Under the push of the nut of the first screw 4, the limit plate 2 also moves toward the baffle 1 with the wire rope joint 10. Since the non-folded end 112 of the wire rope is fixed by the fixing device, the folded end 111 of the wire rope enters the wire rope joint 10. After loosening the first nut 5, the elastic member and manpower can be used to reset the limit plate 2 and then perform the next cycle of operation.

[0032] It should be noted that the pushing device can also adopt other types of devices, as long as it can drive the limit plate 2 to move toward the folded end 111 of the wire rope, such as using a hydraulic cylinder to connect the limit plate 2, replacing the first nut 5 with a handwheel or rocker, etc.

[0033] In this embodiment, the base includes an upper plate and a lower plate, which are fixedly connected by side plates. The upper plate, the lower plate and the side plates are all steel plates. The lower plate is used to place the drilling rig base 12. A through hole is provided on the upper plate for the second screw 8 to pass through and abut the drilling rig base 12 to fix the drilling rig base 12 to the lower plate. The second screw 8 is used to fix the drilling rig base 12 to realize a detachable connection between the drilling rig base 12 and the base.

[0034] In this embodiment, the through hole is an elongated hole and extends along the length direction of the first screw rod 4. The second screw rod 8 can move along the elongated hole. The second screw rod 8 passes downward through the elongated hole and is screwed with a second nut 9. The second nut 9 is attached to the lower side of the upper plate to prevent the second screw rod 8 from moving. The setting of the elongated hole allows the position of the second screw rod 8 therein to be adjusted, which can adapt to drilling rig bases 12 of different types and sizes. Elongated holes are provided on the bases on both sides of the first screw rod 4, and two second screws 8 are provided in each elongated hole. According to the form of the drilling rig base 12, the two second screws 8 are respectively located at appropriate positions at the two ends of the elongated hole to ensure that the drilling rig base 12 is locked and fixed to the base.

[0035] In this embodiment, the fixing device includes two oppositely arranged splints 3, which are connected and locked by a third screw 6 and a third nut 7. Two third screws 6 are arranged up and down along the height direction of the splint 3, and the third screw 6 passes through the through hole of the splint 3 and is fixed by the third nut 7. The nut of the third screw 6 abuts the outer side of one splint 3, and the nut is locked to the outer side of the other splint 3, so that the two splints 3 can jointly clamp the non-folded end 112 of the wire rope. Since it may take multiple cycles for the wire rope to enter the wire rope joint 10, when the wire rope joint 10 moves to the extreme position close to the baffle 1 and cannot continue to move close to the baffle 1, loosen the third nut 7, pull the non-folded end 112 of the wire rope further out of the splint 3, lock the third nut 7 after reaching the appropriate position, and continue the next cycle of wire rope movement.

[0036] In this embodiment, the clamping plate 3 is slidably arranged on the base in a direction perpendicular to the first screw rod 4, so that the clamping plate 3 can clamp steel wire ropes of different thicknesses and can adapt to more working conditions.

[0037] In this embodiment, the baffle 1 and the limit plate 2 are both provided with semicircular holes on the top to assist the wire rope to pass through. The wire rope is placed in the semicircular holes, and the elastic member is set as a spring 13. One end of the spring 13 abuts the baffle 1, and the other end abuts the wire rope joint 10. There is friction between the end abutting the baffle 1 and the baffle 1. When the folded end 111 of the wire rope leaves the baffle 1, the spring 13 is used to provide support for the wire rope and ensure that the folded end 111 of the wire rope can eventually fully enter the wire rope joint 10. The semicircular hole provides a space for the wire rope to be laid, so that the folded section 111 of the wire rope can move downward, and then the spring can also Relative to the baffle plate, the setting of the semicircular hole helps the spring 13 to abut against the baffle plate 1 with a larger area, which can ensure that the friction force is sufficient to support the folded end 111 of the wire rope. When the folded end 111 of the wire rope extends out of the baffle plate 1, the semicircular hole can have a certain supporting effect. When the position of the folded end 111 of the wire rope cannot reach the baffle plate 1, the supporting force of the wire rope is completely provided by the spring 13, and the space inside the spring 13 provides movement space for the folded end 111 of the wire rope, ensuring that the folded end 111 of the wire rope can eventually fully enter the wire rope joint 10, making the connection between the wire rope and the wire rope joint 10 more secure.

[0038] In this embodiment, the bottom cross-sections of the limiting plate 2 and the bottom cross-sections of the splint 3 are both inverted T-shaped cross-sections. A first inverted T-shaped groove corresponding to the bottom end of the limiting plate 2 is provided on the base, and the first inverted T-shaped groove is provided along the length direction of the first screw 4, which can ensure the stable sliding of the limiting plate 2 relative to the base. A second inverted T-shaped groove corresponding to the bottom end of the splint 3 is also provided on the base, and the second inverted T-shaped groove is provided in a direction perpendicular to the first screw 4, which can ensure the stable sliding of the splint 3 relative to the base and prevent the limiting plate 2 and the splint 3 from tipping over.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
