[0002] A cable wellhead pulley is a device used for laying and transporting cables in a wellhead or pipeline. It is usually composed of a pulley and a bracket, and is used to support and guide the cables to ensure that they move smoothly during transportation. The brackets of existing wellhead pulleys mostly adopt an 'L'-shaped structure. Through its special structure, it is directly connected to one side of the wellhead. The limiting method of this type of structure is: the downward pressure exerted by the cable passing from above and the upward reverse supporting force of the bracket interact with each other, forming the ability to limit and fix in the vertical direction.

[0003] However, the support and limiting method of the above-mentioned bracket lacks supporting force from the side. When the cable deflects slightly to one side during transportation, it will easily cause the bracket box to deflect to the side, thereby causing the bracket to tip over and over, making it impossible to assist the cable laying work normally. Therefore, we propose a cable wellhead pulley for cable laying to solve this problem. Summary of the invention

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Example 1

[0035] Reference Figure 1 to Figure 12 , which is the first embodiment of the present invention, provides a cable wellhead pulley for cable laying, the device includes an installation unit 100, including a limiting component 101, an adjusting component 102 sleeved on the limiting component 101, and three groups of supporting components 103 centered around the center of the limiting component 101 and distributed around the outside of the limiting component 101, one end of the supporting component 103 extends into the limiting component 101, the adjusting component 102 is sleeved on the limiting component 101, and can rotate around the limiting component 101; and,

[0036] The support unit 200 includes two sets of mounting frames 201 horizontally mounted above the limiting component 101, and the bottom ends of the mounting frames 201 are fixedly connected to the top surface of the limiting component 101, and lifting components 202 are arranged on the mounting frames 201. There are two sets of mounting frames 201, which are fixed to the top of the limiting component 101 in a parallel manner, and the lifting components 202 are interactively connected to the mounting frames 201 and can slide horizontally according to needs.

[0037] During use, according to the wellhead size of the cable well, by rotating the adjusting component 102, the three groups of supporting components 103 can be driven to extend outward from the bottom of the limiting component 101, and the outwardly extending supporting component 103 can be abutted against the well wall in the cable well to limit and fix the installation unit 100 as a whole in the cable well. Subsequently, the cable is guided through the top of the lifting component 202 and inserted into the limiting component 101. At this time, the cable can penetrate into the cable well through the limiting component 101.

[0038] Example 2

[0039] Reference Figure 2~Figure 10 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that it can adjust the installation range accordingly according to the size of the cable wellhead, providing stronger and more effective stable support.

[0040] Compared with Example 1, further, the limiting component 101 includes a limiting disk 101a with a circular structure, a limiting shaft 101b fixedly connected to the bottom of the limiting disk 101a, and the interior of the limiting shaft 101b is connected to the interior of the limiting disk 101a, three groups of limiting seats 101c are distributed on the outer wall of the limiting shaft 101b with the center of the circle below the limiting shaft 101b as the center point, and corresponding limiting grooves 101d are opened on the three groups of limiting seats 101c, and three groups of supporting components 103 are correspondingly inserted in the limiting grooves 101d, the limiting disk 101a is fixedly connected to the limiting shaft 101b, the limiting seat 101c is fixedly connected to the limiting shaft 101b, the two sides of the limiting groove 101d are rectangular surfaces, and the supporting component 103 is slidably inserted in the limiting groove 101d, and can slide horizontally along it.

[0041] Among them, the limiting component 101 also includes two groups of support plates 101e symmetrically connected to the inner side of the limiting shaft 101b, two groups of slide grooves 101f correspondingly opened horizontally on the two groups of support plates 101e, and a first guide wheel 101g arranged between the two groups of support plates 101e, and both ends of the first guide wheel 101g extend into the corresponding slide groove 101f. The two groups of support plates 101e can support the first guide wheel 101g, and the first guide wheel 101g is installed on the support plate 101e through threads. By controlling the tightness of the threads, the first guide wheel 101g can be fixed at any position in the slide groove 101f, thereby realizing the arbitrary sliding of the first guide wheel 101g in the limiting plate 101a.

[0042] Among them, the adjusting component 102 includes an adjusting disk 102a with an annular structure sleeved on the limiting shaft 101b, three groups of storage grooves 102b distributed in an annular manner on the top surface of the adjusting disk 102a, three groups of handles 102c correspondingly arranged in the three groups of storage grooves 102b, and a driving rack 102d arranged on the bottom surface of the adjusting disk 102a. The handle 102c is rotatably connected to the top of the adjusting disk 102a, but the two sides of the adjusting disk 102a are limited by the storage grooves 102b. Therefore, the adjusting disk 102a can be operated to rotate by grasping the handle 102c.

[0043] Among them, the driving rack 102d is in a spiral structure and is coiled on the bottom surface of the adjusting disk 102a, and the number of spiral turns of the driving rack 102d is 3 turns. The spiral direction of the driving rack 102d is spirally expanded from the inner side of the bottom surface of the adjusting disk 102a to the outside. The top of the spiral structured driving rack 102d is fixedly connected to the adjusting disk 102a, so when the adjusting disk 102a rotates, the storage slot 102b can be driven to rotate synchronously.

[0044] Among them, the supporting component 103 includes a telescopic rod 103a slidably inserted in the driving rack 102d, engaging blocks 103b evenly distributed on the top surface of the telescopic rod 103a, a contact block 103c arranged at the outer end of the telescopic rod 103a, and a driving groove 103d located between every two groups of engaging blocks 103b, and the driving rack 102d is located in the driving groove 103d, and the two sides of the telescopic rod 103a are rectangular structures and fit on both sides of the limiting groove 101d, and can slide horizontally along the limiting groove 101d, but cannot rotate in a circle.

[0045] Furthermore, the bottom surface of the contact block 103c is a stepped structure. There are three groups of end faces that are not on the same horizontal line. In actual use, any one group of the two lower groups of end faces of the stepped bottom surface of the contact block 103c is extended into the wellhead, and the other parts are located outside the wellhead and abut against the upper surface of the ground outside the wellhead to form a snap-on structure. At this time, the contact block 103c can interact with the ground through the bottom end face to form a reverse supporting force that strengthens the supporting stability of the support component 103.

[0046] During use, according to the actual size of the cable wellhead, the driving adjustment component 102 rotates around the limiting shaft 101b, and the rotating adjustment component 102 drives the driving rack 102d to rotate. At this time, the rotating driving rack 102d will abut against the engagement block 103b through its unique spiral structure, and because the telescopic rod 103a is limited by the limiting groove 101d, the telescopic rod 103a can only extend outward along the limiting groove 101d, thereby pushing the contact block 103c to move outward. In this process, the three groups of support components 103 are synchronously driven by the adjusting component 102 to extend and expand outward, so as to realize the function of adjusting the installation range according to the size of the cable wellhead;

[0047] When the support component 103 is expanded to meet the size of the cable wellhead, the installation unit 100 is placed above the wellhead as a whole, so that the limit plate 101a is concentric and coaxial with the wellhead. In order to further enhance the supporting effect, the extension amplitude of the three groups of support components 103 is then fine-tuned so that the bottom outer side of the contact block 103c at the outer end of the three groups of support components 103 abuts against the inner wall of the cable well, and then any one of the two groups of end faces of the stepped bottom surface of the contact block 103c is extended into the wellhead, so that the end face of the contact block 103c located in the wellhead abuts against the inner wall of the cable well, thereby making the contact block abutting against the inner wall of the cable well. A mutual supporting force in the horizontal direction is formed between 103c and the cable well, while the other parts are located outside the wellhead and abut against the upper surface of the ground outside the wellhead. At this time, the contact block 103c can abut against the ground through the bottom end face to interact with each other to form a supporting force in the vertical direction. The device is provided with three groups of supporting components 103 at different positions, so a total of three groups of horizontal supporting forces and three groups of vertical supporting forces at different positions can be formed. Through the combination and mutual action of multiple supporting forces, a safe, reliable and stable supporting structure can be formed, which can effectively avoid the occurrence of rollover and overturning problems.

[0048] The remaining structures are the same as those of Example 1.

[0049] Example 3

[0050] Reference Figure 11~Figure 12 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the position of the top supporting point of the support unit 200 is changed according to the size of the cable entering the well, so as to adjust the curvature of the cable entering the cable well and meet different usage requirements.

[0051] Compared with Example 2, further, the mounting frame 201 includes a sliding bar 201a horizontally arranged on the top surface of the limiting plate 101a, a movable groove 201b horizontally opened on the sliding bar 201a, and the movable groove 201b passes through the outside of the sliding bar 201a and is connected, a slot 201c vertically arranged on the top surface of the sliding bar 201a, and the slot 201c passes through the sliding bar 201a upward, and the sliding bar 201a is fixedly connected to the top surface of the limiting plate 101a.

[0052] Among them, the lifting component 202 includes two groups of support frames 202a symmetrically arranged between the two groups of mounting frames 201, a slider 202b arranged at one end of the outer side of the support frame 202a, and the slider 202b extends into the movable groove 201b, a limiting plate 202c arranged on the outer side of the slider 202b, a limiting bolt 202d vertically arranged above the slider 202b, and the limiting bolt 202d extends upward into the slot 201c, and a limiting nut 202e threadedly connected to the limiting bolt 202d, and the bottom surface of the limiting nut 202e abuts against the top surface of the slide bar 201a, the slider 202b can slide horizontally in the movable groove 201b, and the limiting nut 202e can limit and fix the lifting component 202 at any position of the mounting frame 201 by cooperating with the thread of the limiting bolt 202d, thereby playing a role of limiting and fixing.

[0053] During use, the cable is passed through the second guide wheel 202f, the third guide wheel 202g and the first guide wheel 101g. The second guide wheel 202f located at the top of the triangular structure support frame 202a can support the cable. When the cable size is thicker, the limiting nut 202e is rotated to make the connection between the lifting component 202 and the mounting frame 201 contact, and then the lifting component 202 is pushed along the movable groove 201b. At this time, the lifting component 202 moves outward as a whole, and the second guide wheel 202f at its top will also lift the cable as it moves, so that there is a drop in the cable between the second guide wheel 202f and the first guide wheel 101g. Then the limiting nut 202e is rotated in the opposite direction to fix the lifting component 202 as a whole. The cable is first lifted by lifting the lifting component 202, and then the cable height is lowered after passing through the first guide wheel 101g, which can increase the angle of the cable entering the well, thereby avoiding the wear problem caused by the small angle when the cable enters the well, thereby ensuring the safety of the cable.

[0054] The structure is the same as that of Example 2.
