Description

Technical Field

[0001] This utility model relates to a liftable cable laying device, belonging to the technical field of oil well extraction equipment. Background Technology

[0002] Cable laying devices are key equipment for optimizing cable laying efficiency. Their core function is to arrange cables in an orderly manner, preventing cable tangling, cable clamping, and other faults. Existing cable laying devices have the following problems: the height of the cable laying device is fixed. When changing to different specifications of cable rollers, it is impossible to adjust the height of the cable laying device to set a reasonable cable extraction angle, which increases the amount of cable deformation during operation and affects the service life of the cable; it cannot measure the passing cables and cannot accurately record the length of cables deployed or retrieved. Utility Model Content

[0003] The purpose of this invention is to provide a liftable cable laying device. The height of the guide mechanism can be adjusted through the lifting mechanism to adapt to cable drums of different outer diameters. The tilt angle of the guide can be flexibly adjusted, and the length of the passing cable can be accurately measured to ensure that the cable has a suitable removal angle on the cable drum, thereby extending the service life of the cable and solving the problems existing in the background technology.

[0004] The technical solution of this utility model is: A liftable cable laying device includes a base, a counter, a guide, a guiding mechanism, and a lifting mechanism. The lifting mechanism is provided on the base, the guiding mechanism is installed on the lifting mechanism, the guide is provided on the guiding mechanism, and the counter is provided on the guide. The guiding mechanism includes a lead screw, a cable laying hydraulic motor, a guide slider, and a guide mounting base. The lead screw is connected to the cable laying hydraulic motor, and the guide slider is slidably mounted on the lead screw. The top of the guide slider is connected to the guide mounting base. The guide includes a guide horizontal roller, a guide vertical roller, an upper housing, a lower housing, and a guide support rod. There are four guide vertical rollers, all mounted on the lower housing. A cable is placed between the four guide vertical rollers. There are also four guide horizontal rollers; two are mounted on the upper housing, contacting the upper surface of the cable, and the other two are mounted on the lower housing, contacting the lower surface of the cable. The upper and lower housings are connected, the lower housing is connected to the guide support rod, and the guide support rod is connected to the guide mounting base. The counter includes a tension spring, a counting wheel, a counting wheel shaft, and a counter housing. The two ends of the tension spring are connected to the upper housing and the counter housing, respectively, and the counter housing is hinged to the upper housing. The counting wheel is mounted on the counter housing via the counting wheel shaft and is in contact with the cable.

[0005] The lifting mechanism consists of two support slide rails and a lifting platform. The two support slide rails are fixed on the base, and each support slide rail is provided with two slide rail beams. The four corners of the lifting platform are provided with four square sleeves, which are respectively fitted onto the four slide rail beams of the two support slide rails. The lifting platform can move up and down along the slide rail beams. A guide mechanism is installed on the lifting platform.

[0006] Each support slide rail is equipped with a lifting cylinder inside. The cylinder body of the lifting cylinder is mounted on the base, and the cylinder rod of the lifting cylinder is connected to the lifting platform. The lifting platform is moved up and down by extending and retracting the lifting cylinder, thereby realizing the adjustment of the height of the guide mechanism. The height of the guide mechanism can be adjusted according to the different outer diameters of the cable drum, so as to ensure that the cable drum has a suitable extraction angle so that the cable can be successfully retrieved and deployed.

[0007] The bottom ends of the guide mounting base are respectively provided with guide shaft mounting bases, and guide shafts are provided on the guide shaft mounting bases; cylindrical sleeves are respectively provided on the guide slider and the guide mounting base between the two guide shaft mounting bases.

[0008] The guide support rod has an inverted U-shaped structure and includes a connecting seat and two support rods, both of which are connected to the connecting seat; the two support rods are respectively inserted into two cylindrical sleeves.

[0009] The distance between the guide slider and each guide shaft mounting seat is slightly larger than the inner diameter of the cylindrical sleeve.

[0010] The counter housing is mounted on the ear plate of the upper housing via a second pin and can rotate around the second pin.

[0011] The counting wheel shaft is connected to the electronic encoder. During operation, the counter housing rotates around the second pin shaft. The tension of the spring ensures close contact between the counting wheel and the cable. Torque is transmitted between the counting wheel and the counting wheel shaft via a flat key. The friction between the counting wheel and the cable drives the counting wheel shaft to rotate, thereby driving the electronic encoder and achieving counting.

[0012] The upper and lower housings are connected by four fastening bolts, and the lower housing is connected to the guide support rod by a pin.

[0013] The guide has an openable / closing structure for easy cable removal and installation. Two bearings are installed on each guide's horizontal and vertical rollers. In use, remove the four fastening bolts on the upper housing, remove the upper housing along with the two guide's horizontal rollers mounted on it, place the cable between the four guide's vertical rollers on the lower housing, then reattach the upper and lower housings, and tighten the four fastening bolts. Cable laying is done manually using a forced cable laying handle. Operating the forced cable laying handle causes the hydraulic motor to drive the screw to rotate, which in turn moves the guide along the cable's rolling width, thus laying the cable. Furthermore, because the guide support rod is located inside the cylindrical sleeve of the guide mounting base, the guide can float up and down with the cable as a whole, depending on the cable tension. The guide support rod and the lower housing are connected by a pin, allowing for flexible adjustment of the guide's tilt angle to accommodate the cable's removal angle on the cable drum.

[0014] The lead screw, cable laying hydraulic motor, cable drum, lifting cylinder, and electronic encoder mentioned are all commonly known and widely used devices in the field.

[0015] This invention involves leading one end of the cable from the cable drum, passing it through the guide, and continuing until it reaches the wellhead of the oil well; adjusting the height of the guide mechanism via a lifting mechanism to move the guide in the cable rolling width direction to lay the cable; and measuring the length of the cable that has passed through using a counter.

[0016] The beneficial effects of this utility model are: the height of the guide mechanism can be adjusted by the lifting mechanism, which can adapt to cable drums of different outer diameters and has better adaptability to cable drums; the tilt angle of the guide can be flexibly adjusted and the length of the cable passing through can be accurately measured to ensure that the cable has a suitable extraction angle on the cable drum, so that the cable can be smoothly recycled and deployed, thus extending the service life of the cable.

[0021] Each support slide rail 501 is equipped with a lifting cylinder 7 on its inner side. The cylinder body of the lifting cylinder 7 is mounted on the base 1, and the cylinder rod of the lifting cylinder 7 is connected to the lifting platform 503. The lifting platform 503 is moved up and down by the extension and retraction of the lifting cylinder 7, thereby realizing the adjustment of the height of the guide mechanism 4. The height of the guide mechanism 4 can be adjusted according to the different outer diameters of the cable drum, so as to ensure that the cable drum has a suitable extraction angle so that the cable can be successfully retrieved and deployed.

[0028] In this embodiment, refer to the appendix. Figure 1-3 A liftable cable laying device includes a base 1, a counter 2, a guide 3, a guide mechanism 4, and a lifting mechanism 5.

[0029] The lifting mechanism 5 consists of two support slide rails 501 and a lifting platform 503. The two support slide rails 501 are fixed on the base 1, and each support slide rail 501 has two slide rail beams. The lifting platform 503 has four square sleeves 502 at its four corners, which are respectively fitted onto the four slide rail beams of the two support slide rails 501. The lifting platform 503 can move up and down along the slide rail beams. The guide mechanism 4 is installed on the lifting platform 503. One end of the lifting cylinder 7 is installed on the base 1, and the other end is installed on the lifting platform 503. There are two lifting cylinders 7. The lifting platform 503 is moved up and down by extending and retracting the lifting cylinders, thereby adjusting the height of the guide mechanism 4. The height of the guide mechanism 4 can be adjusted according to the cable drum 6 with different outer diameters to ensure that the cable drum has a suitable extraction angle so that the cable can be retrieved and deployed smoothly. The guide mechanism 4 is equipped with a lead screw 401 and a guide 3. The cable laying method is manual forced cable laying. The cable laying hydraulic motor 402 of the guide mechanism 4 directly drives the lead screw 401 to rotate, which drives the guide 3 to move left and right along the width direction of the cable drum to realize cable laying.

[0030] The guide 3 has an openable structure for easy cable removal and installation. The guide 3 includes a horizontal guide roller 301, a vertical guide roller 302, an upper housing 304, a lower housing 305, and a guide support rod 306. There are four vertical guide rollers 302, all mounted on the lower housing 305. A cable 303 is placed between the four vertical guide rollers 302. There are also four horizontal guide rollers 301; two are mounted on the upper housing 304, contacting the upper surface of the cable 303, and the other two are mounted on the lower housing 305, contacting the lower surface of the cable 303. Two bearings are mounted on each horizontal guide roller 301 and each vertical guide roller 302. The upper housing 304 and lower housing 305 are connected by four fastening bolts. The lower housing 305 is connected to the guide support rod 306 by a pin. The guide support rod 306 is housed within the cylindrical sleeve of the guide mechanism 4. In use, remove the four fastening bolts on the upper housing 304, remove the upper housing 304 along with the two guide horizontal rollers 301 mounted on it, place the cable 303 between the four guide vertical rollers 302 of the lower housing 305, then reattach the upper housing 304 to the lower housing 305, and tighten the four fastening bolts. Operate the cable routing handle to drive the screw 401 to rotate using the forced cable routing hydraulic motor 402, thereby moving the guide 3 in the cable rolling width direction to route the cable. In addition, since the guide support rod 306 of the guide 3 is set inside the cylindrical sleeve 407 of the guide mounting base 305, the guide 3 can float up and down with the cable 303 as a whole according to the tension of the cable 303. Furthermore, the guide support rod 306 and the lower housing 304 are connected by a pin. Therefore, the tilt angle of the guide 3 can be flexibly adjusted to adapt to the removal angle of the cable 303 on the cable drum 6.

[0031] The counter 2 includes a tension spring 201, a counting wheel 202, a counting wheel shaft 203, and a counter housing 205. The tension spring 201 is connected at both ends to the upper housing 304 and the counter housing 205, respectively. The counter housing 205 is mounted on the ear plate of the upper housing 304 via a second pin 204 and can rotate around the second pin 204. The counting wheel 202 is mounted on the counter housing 205 via the counting wheel shaft 203, and the counting wheel 202 is in contact with the cable 303. The counting wheel shaft 203 is connected to an electronic encoder. During operation, the counter housing 205 rotates around the second pin 204. The tension of the tension spring 201 ensures close contact between the counting wheel 202 and the cable 303. Torque is transmitted between the counting wheel 202 and the counting wheel shaft 203 via a key. The friction between the counting wheel 202 and the cable 303 drives the counting wheel shaft 203 to rotate, thus driving the electronic encoder and achieving counting.

[0032] The operation process of this utility model is as follows: During operation, one end of the cable on the cable drum 6 is led out, passes through the guide 3, and follows the guiding direction of the top pulley 9 and the bottom pulley 8 until it reaches the wellhead. The lifting platform 503 is moved up and down by the extension and retraction of the lifting cylinder 7, thereby adjusting the height of the guide mechanism 4. The lead screw 401 of the guide mechanism 4 rotates, causing the guide slider 403 to drive the guide 3 to move in the cable rolling width direction to lay the cable. The counter housing 205 is installed on the outer shell of the guide 3. After the cable passes through the guide 3, the tension of the tension spring 201 is adjusted so that the counting wheel 202 contacts the cable 303 with a suitable clamping force. The friction between the counting wheel 202 and the cable 303 drives the counting wheel 202 to rotate, thereby measuring the length of the cable that has passed. At this time, an operator controls the forced cable laying hydraulic motor 402 through the operating handle, and adjusts the position of the guide mechanism 4 and the guide 3 at any time according to the position of the cable removal point in the width direction of the cable drum to ensure that the cable is successfully removed.

[0033] This invention uses a lifting mechanism to adjust the height of the guiding mechanism, ensuring a suitable extraction angle on the cable drum for smooth cable retrieval and deployment. A guide device guides the cable, allowing it to float up and down with the cable as a whole, adjusting its tilt angle to accommodate the extraction angle of the cable on the cable drum. A counter measures the length of the cable passing through.
