Description

Technical Field

[0001] The invention relates to the technical field of cable laying, in particular to a wellhead cable laying and fixing device. Background Art

[0002] When conducting underground operations, such as mining operations, oil well operations and gas well operations, various instruments and equipment will be used underground. In order to provide power to the underground or ensure communication between the underground and the ground, cables will be laid at the wellhead. Generally, cable laying equipment will be set up at the wellhead for underground cable laying operations and cable fixation.

[0003] The cable to be laid in the cable laying equipment is usually wound on the surface of the drum. When laying and paying out the cable, the traditional cable laying and fixing equipment is affected by the inertia of the cable paying out and the deadweight of the cable laid underground. When the cable laying length meets the requirements, the drum may continue to rotate and pay out the cable, which will result in over-travel pay-out, resulting in the cable laying length being too long and the cable laying direction being poor. At the same time, after the cable laying length meets the requirements, the drum continues to rotate, which will loosen the cable on its surface, resulting in tangled cables on the surface of the drum, which will not only affect the subsequent laying and paying out of the cable, but also affect the winding of the cable. Summary of the invention

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0016] The embodiment of the wellhead cable laying and fixing device is as follows: See also Figure 1-Figure 10 A wellhead cable laying and fixing device comprises a base 1, a laying box 3 and a cable release port 31 opened at the bottom thereof. The middle of the base 1 is a channel, and the channel corresponds to the wellhead. A "door"-shaped mounting frame 2 is fixedly installed on the upper surface of the base 1. The inner side walls of the mounting frame 2 are slidably installed with connecting blocks 21, and the outer side walls of the laying box 3 are fixedly connected to the connecting block 21.

[0017] A vertical adjusting screw 22 is rotatably installed inside the mounting frame 2, and a motor device for driving the adjusting screw 22 to rotate is installed on the top of the mounting frame 2. The adjusting screw 22 is threadedly connected to the connecting block 21. The adjusting screw 22 is driven to rotate by the motor device to adjust the position of the laying box 3 up and down. When the laying box 3 is on the lower side, it is convenient for the operator to lay the cable in the laying box 3. When the laying box 3 is on the upper side, it is convenient for the operator to enter the wellhead through the passage.

[0018] A wire reel 4 is installed inside the laying box 3, and the cable to be laid is wound on the surface of the wire reel 4. Both ends of the wire reel 4 are rotatably connected to the inner wall of the laying box 3 through a connecting shaft 41. The connecting shaft 41 is fixedly connected to the wire reel 4. A fixing ring 42, a driving ring 5 and a limiting cylinder 6 are provided between the side end surface of at least one side of the wire reel 4 and the interior of the laying box 3. The fixing ring 42, the driving ring 5 and the limiting cylinder 6 are all sleeved on the surface of the connecting shaft 41. The fixing ring 42 is fixedly installed on the side end surface of the wire reel 4, the driving ring 5 is arranged on the inner wall of the laying box 3, and the limiting cylinder 6 is located between the fixing ring 42 and the driving ring 5.

[0019] The fixing ring 42, the driving ring 5 and the limiting cylinder 6 are coaxially designed. One end of the limiting cylinder 6 is axially slidably installed inside the driving ring 5. The limiting cylinder 6 can slide axially relative to the driving ring 5. The interior of the driving ring 5 is concave and is used for installation and cooperation with the limiting cylinder 6. After the driving ring 5 moves a certain distance in the direction of the limiting cylinder 6, it can push the limiting cylinder 6 to move together.

[0020] A friction ring surface 1 421 is provided inside the fixed ring 42, and a friction ring surface 2 61 is provided at one end of the limiting cylinder 6 close to the fixed ring 42. The friction ring surface 2 61 is matched with the friction ring surface 1 421. When the friction ring surface 2 61 and the friction ring surface 1 421 are matched, the limiting cylinder 6 and the fixed ring 42 are relatively fixed in the rotation direction.

[0021] The friction ring surface 1 421 is funnel-shaped, and the friction ring surface 2 61 is frustum-shaped, which is used to increase the contact area between the friction ring surface 2 61 and the friction ring surface 1 421 and facilitate the separation of the limiting cylinder 6 and the fixing ring 42 .

[0022] An auxiliary guide roller 8 is rotatably installed inside the laying box 3. The cable to be laid is wound around the surface of the auxiliary guide roller 8 at least once and then output from the pay-off port 31. The auxiliary guide roller 8 generates a torsional force by pulling and paying out the cable.

[0023] A linkage mechanism is provided between the auxiliary guide roller 8 and the driving ring 5, and the linkage mechanism includes an adjusting ring 2 7 and an adjusting rod 91. The adjusting ring 2 7 is fixedly mounted on the surface of the limiting cylinder 6, and a switching ring 71 is rotatably mounted on the surface of the adjusting ring 2 7. A support member 9 is fixedly mounted on the inner wall of the laying box 3, and the middle section of the adjusting rod 91 is rotatably connected to the support member 9.

[0024] An adapter shaft is fixedly installed on the side wall of the adapter ring 71, and a strip groove is opened at one end of the adjusting rod 91, and the adapter shaft is located in the strip groove. When the auxiliary guide roller 8 generates a torsional force, the adjusting rod 91 is driven to rotate by the torsional force, and then the limiting cylinder 6 is driven to move axially. The connection between the support member 9 and the adjusting rod 91 is closer to the end where the adjusting rod 91 is connected to the adapter shaft, which is used to reduce the rotation force arm between the connection and the adapter shaft.

[0025] An adjusting disk 81 is installed at at least one end of the auxiliary guide roller 8. The adjusting disk 81 and the end of the auxiliary guide roller 8 are frictionally rotated together. The auxiliary guide roller 8 can drive the adjusting disk 81 to rotate through static friction. When the torsional force of the auxiliary guide roller 8 is greater than the static friction between it and the adjusting disk 81, the auxiliary guide roller 8 can rotate relative to the adjusting disk 81. A protrusion 811 is provided on the surface of the adjusting disk 81. When the protrusion 811 rotates, it can contact the end of the adjusting rod 91 away from the adapter ring 71. The protrusion 811 is used to push the adjusting rod 91 to rotate. A reset spring is provided between the adjusting rod 91 and the inner wall of the laying box 3. When the protrusion 811 is separated from the adjusting rod 91, the reset spring is used to drive the adjusting rod 91 to reset.

[0026] A limit plate 82 is fixedly installed on the inner wall of the laying box 3. The limit plate 82 is located on one side of the adjusting plate 81. An arc-shaped limit groove 821 is provided on the surface of the limit plate 82. An axle is provided between the limit plate 82 and the adjusting plate 81. The axle is fixedly connected to the adjusting plate 81 and is rotatably connected to the limit plate 82. A torsion spring 822 is provided between the axle and the limit plate 82. When the torsional force of the auxiliary guide roller 8 disappears, the torsion spring 822 is used to reset the adjusting plate 81.

[0027] A matching block 812 is provided on the surface of the adjusting disk 81 . The matching block 812 is located inside the limiting groove 821 . The matching block 812 matches with the limiting groove 821 to limit the rotation range of the adjusting disk 81 .

[0028] When laying the cable, the driving ring 5 is fixedly connected to the inner wall of the laying box 3, and the auxiliary guide roller 8 generates a torsional force. The linkage mechanism is used to axially adjust the position of the limit cylinder 6 to separate it from the fixed ring 42. In this state, the wire drum 4 can rotate. When the cable is pulled down to the inside of the wellhead for laying, the wire drum 4 rotates with the laying of the cable, thereby releasing the cable. When the auxiliary guide roller 8 has no torsional force, the limit cylinder 6 cooperates with the fixed ring 42 to limit the rotation of the wire drum 4. In this state, the driving ring 5 and the limit cylinder 6 cooperate with the fixed ring 42 to limit the rotation of the wire drum 4.

[0029] When pulling down to lay the cable, the auxiliary guide roller 8 is designed to reduce the pulling force on the cable on the surface of the wire drum 4 caused by the deadweight of the cable laid inside the wellhead, so as to prevent the cable on the surface of the wire drum 4 from being pulled down and released by the deadweight of the cable without artificial pulling. At the same time, the auxiliary guide roller 8 generates a torsional force by manually pulling down the laid cable. When there is no artificial pulling down, the torsional force of the auxiliary guide roller 8 disappears, and the torsion of the auxiliary guide roller 8 controls the cooperation relationship between the drive ring 5 and the limit cylinder 6 and the fixed ring 42, so that when there is no artificial pulling down of the cable, the wire drum 4 has a certain rotational resistance, so as to prevent the wire drum 4 from over-travel rotation due to the inertia of cable release or the deadweight of the laid cable, which can not only improve the pay-out effect of cable laying, but also prevent the wire drum 4 from rotating in a disorderly manner due to over-travel rotation.

[0030] An adjusting ring 52 is rotatably installed on the surface of the driving ring 5, and a hydraulic rod 11 is installed on the inner wall of the laying box 3. The telescopic end of the hydraulic rod 11 is fixedly connected to the adjusting ring 52. The position of the driving ring 5 is axially adjusted by the hydraulic rod 11. A plurality of slots 51 are opened on the surface of the driving ring 5.

[0031] A fixed disk 12 is fixedly installed on the inner wall of the laying box 3. The fixed disk 12 is located on one side of the driving ring 5. A plurality of clamping strips 121 are fixedly arranged on the surface of the fixed disk 12. When the driving ring 5 moves axially, the clamping groove 51 can cooperate with the clamping strip 121. When the clamping groove 51 on the surface of the driving ring 5 is in a matched state with the clamping strip 121, the driving ring 5 cannot rotate. This state is used in the cable laying process. When the clamping groove 51 and the clamping strip 121 are in a separated state, the driving ring 5 can rotate. At the same time, the axial movement of the driving ring 5 will push the limiting cylinder 6 to move axially, so that the limiting cylinder 6 and the fixed ring 42 are in a matched state.

[0032] A gear ring 10 is fixedly installed on the surface of the driving ring 5, and a motor is installed inside the laying box 3. A gear is installed at the output end of the motor, and the gear is meshed with the gear ring 10. When the driving ring 5 moves axially, the gear always keeps meshing with the gear ring 10. When the slot 51 and the clamping strip 121 are in a separated state, the motor is started, and the driving ring 5 is driven by the motor to rotate. The driving ring 5 drives the fixed ring 42 to rotate together through the limit cylinder 6, and the fixed ring 42 drives the wire drum 4 to rotate, and the rotation of the wire drum 4 is utilized to reel in the laid cable.

[0033] A screw rod 13 is provided above the auxiliary guide roller 8, and a motor module for driving the screw rod 13 to rotate is installed on the outer wall of the laying box 3. The screw rod 13 is rotatably installed inside the laying box 3, and a guide rod 14 is provided parallel to the side of the screw rod 13. A guide block 15 is provided between the screw rod 13 and the guide rod 14. The guide block 15 is threadedly connected to the screw rod 13, and the guide block 15 is slidably connected to the guide rod 14. A penetrating guide hole is opened on the surface of the guide block 15, and the cable passes through the guide hole. When the motor module drives the screw rod 13 to rotate, the movement of the guide block 15 is used to control the laying or winding position of the cable, which is convenient for laying and releasing the cable on the surface of the bobbin 4, or for evenly winding the cable onto the surface of the bobbin 4.

[0034] Working principle of the wellhead cable laying and fixing device: First, set up the base 1 and the mounting frame 2 above the wellhead so that the channel in the center of the base 1 corresponds to the wellhead up and down, then start the motor device on the top of the base 1, use the motor device to drive the adjusting screw 22 to rotate, and use the cooperation of the adjusting screw 22 and the connecting block 21 to adjust the height of the laying box 3 upwards so that the downhole operators can enter the well through the channel. At this time, the lower end of the cable to be laid in the laying box 3 has extended into the wellhead through the wire-laying port 31.

[0035] The operator pulls down the cable in the well to lay the cable. When the cable is pulled down, it will generate a force on the auxiliary guide roller 8, which in turn causes the auxiliary guide roller 8 to generate a torsional force. The auxiliary guide roller 8 drives the adjusting disk 81 to rotate. When the raised portion 811 on the surface of the adjusting disk 81 contacts the adjusting rod 91, it pushes the adjusting rod 91 to rotate. The adjusting rod 91 drives the limit cylinder 6 to move axially through the adapter ring 71 and the adjusting ring 27, so that the limit cylinder 6 is separated from the fixing ring 42. At this time, the rotation restriction of the wire drum 4 is released, and the wire drum 4 can rotate. The operator pulls down the traction cable to perform underground laying operations on the cable (before the rotation restriction of the wire drum 4 is released, since the cable has a certain tightness, the operator can pull the cable to move one end distance, thereby causing the auxiliary guide roller 8 to generate a torsional force).

[0036] When the operator no longer pulls down the cable, the torsional force of the auxiliary guide roller 8 disappears, the adjusting disk 81 resets and rotates to the initial state, and at the same time the adjusting rod 91 drives the limit cylinder 6 to reset, and the limit cylinder 6 cooperates with the fixing ring 42. At this time, the rotation of the wire drum 4 is restricted, and the cable is no longer released.

[0037] When it is necessary to retract the laid cable, start the hydraulic rod 11, and use the hydraulic rod 11 to push the adjusting ring 52 to move axially. The adjusting ring 52 drives the driving ring 5 to move together, so that the groove 51 on the surface of the driving ring 5 is separated from the clamping strip 121 on the surface of the fixed disk 12. At the same time, the axial movement of the driving ring 5 will tighten the limiting cylinder 6, so that the limiting cylinder 6 is further closely matched with the fixing ring 42. At this time, start the motor inside the laying box 3, and use the engagement of the gear at the output end of the motor with the gear ring 10 to drive the driving ring 5 to rotate. The driving ring 5 drives the wire drum 4 to rotate together through the limiting cylinder 6 and the fixing ring 42, and the wire drum 4 reels the cable.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
