Description

Technical Field

[0001] This utility model relates to the field of oil and gas well perforation technology, and in particular to a pull-out pulley support for perforation. Background Technology

[0002] Oil and gas well perforation pulleys are essential auxiliary equipment in perforation operations. By supporting and guiding the cable, they ensure the perforating tool is smoothly lowered into the well and precisely positioned. Featuring high wear resistance, flexibility, and stability, they are widely used in perforation, logging, and well workover operations. The pulley is installed near the wellhead and secured to the ground or equipment by a fixing device. The cable or wire rope loops around the pulley; the pulley's rotation reduces friction, ensuring smooth lowering and lifting. The pulley supports the cable, preventing it from directly contacting the ground or other equipment, reducing wear and damage. By adjusting the pulley's position and angle, the perforating tool is ensured to be accurately lowered into the target location.

[0003] Conventional perforation pulleys have all been replaced with pulley bracket structures, replacing the previous clamp-fixing structure. Currently, pulley brackets are only used in special perforation conditions, resulting in relatively low usage frequency. Therefore, the design of pulley brackets only considered sturdiness, durability, and reliable support, generally leading to shortcomings such as large size and excessive weight. After long-term and frequent use, the following drawbacks have emerged: the overall bracket design is bulky, making each handling, use, and storage laborious and inconvenient, and requiring significant storage space. Therefore, how to make pulley brackets both lightweight and reliably supportive has become a problem that needs to be solved. Utility Model Content

Connecting seats are fixed to the top ends of the two gantry frames.

[0006] Furthermore, both the bottom of the support plate and the lower surface of the square tube are in contact with the ground.

[0007] Furthermore, the positioning component includes a side plate fixed to the surface of the crossbar, with an insert rod slidably connected through the middle of the side plate. A through hole is provided on the side wall of the square tube near the insert rod. An end plate is fixed to the end of the insert rod away from the through hole, and a tension spring is fixedly connected between the end plate and the side plate. A first locking hole and a second locking hole are provided on the side wall of the inner tube near the positioning component. The first locking hole and the second locking hole are located at both ends of the inner tube, and the second locking hole is located near the support plate. The insert rod can pass through the through hole and be locked into the first locking hole or the second locking hole.

[0008] Furthermore, the square tube has two slots on the side away from the crossbar, and a sliding rod is fixed to the end of the inner tube near the first locking hole. The sliding rod is located on the side near the slots, and the sliding rod passes through the corresponding slots and is slidably connected to the slots.

[0009] Furthermore, the snap-fit ​​assembly includes a mounting block fixed to the upper surface of the square tube, the fixing sleeve can be fitted onto the surface of the mounting block, the side wall of the mounting block has a groove, and a spring is fixedly connected to the inner side wall of the groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-4 As shown, a pull-out pulley bracket for perforation is disclosed, comprising two square tubes 1 and two gantry frames 2. Two crossbars 3 are fixedly connected to both ends of the two square tubes 1. Inner tubes 4 are slidably connected to both ends of the two square tubes 1, and a support plate 5 is fixedly connected to the end of the inner tube 4 outside the square tube 1. Positioning components 6 for fixing the inner tube 4 are provided at both ends of the crossbars 3 near the square tubes 1. Fixing sleeves 7 are fixedly connected to the bottom of the two gantry frames 2. Snap-fit ​​components 8 are fixed to the upper surfaces of both ends of the two square tubes 1. The two fixing sleeves 7 at the bottom of the gantry frames 2 are respectively sleeved on the snap-fit ​​components 8 on the surfaces of the two square tubes 1. Connecting seats 9 are fixed to the top of the two gantry frames 2.

[0022] The bottom of the support plate 5 and the lower surface of the square tube 1 are both in contact with the ground.

[0023] When the inner tube 4 is pulled out from inside the square tube 1, the support plate 5 can be used to support the inner tube 4.

[0024] The positioning component 6 includes a side plate 61 fixed to the surface of the crossbar 3. A rod 62 is slidably connected through the middle of the side plate 61. A through hole 101 is provided on the side wall of the square tube 1 near the rod 62. An end plate 63 is fixed to the end of the rod 62 away from the through hole 101. A tension spring 64 is fixedly connected between the end plate 63 and the side plate 61. A first locking hole 41 and a second locking hole 42 are provided on the side wall of the inner tube 4 near the positioning component 6. The first locking hole 41 and the second locking hole 42 are located at both ends of the inner tube 4, and the second locking hole 42 is located near the support plate 5. The rod 62 can be inserted into the first locking hole 41 or the second locking hole 42 by passing through the through hole 101.

[0025] In its normal state, the tension spring 64 is in a shortened state. At this time, the tension spring 64 will pull the end plate 63 and the insertion rod 62 to move to one side of the square tube 1. When the first locking hole 41 or the second locking hole 42 is aligned with the insertion rod 62, the insertion rod 62 will just pass through the through hole 101 and be inserted into the first locking hole 41 or the second locking hole 42. When the insertion rod 62 is inserted into the first locking hole 41, the inner tube 4 is fixed to the outside of the square tube 1. When the insertion rod 62 is inserted into the second locking hole 42, the inner tube 4 is fixed to the inside of the square tube 1.

[0026] The square tube 1 has two slots 102 on the side away from the crossbar 3. The inner tube 4 has a slide rod 43 fixed at one end near the first locking hole 41. The slide rod 43 is located on the side near the slot 102. The slide rod 43 passes through the slot 102 on the corresponding side and is slidably connected to the slot 102.

[0027] A sliding rod 43 can be slid along the strip opening 102 outside the square tube 1, and the inner tube 4 can be moved inside the square tube 1 by the sliding rod 43.

[0028] The snap-fit ​​assembly 8 includes a mounting block 81 fixed to the upper surface of the square tube 1. A fixing sleeve 7 can be fitted onto the surface of the mounting block 81. A groove 82 is provided on the side wall of the mounting block 81, and a spring 83 is fixedly connected to the inner side wall of the groove 82. A locking tooth 84 is fixedly connected to the other end of the spring 83. A square hole 71 is provided on the side of the fixing sleeve 7 near the locking tooth 84. The end of the locking tooth 84 away from the spring 83 is inserted into the square hole 71. The top of the locking tooth 84 and the side away from the spring 83 are designed with a bevel.

[0029] When connecting the fixing sleeve 7 to the mounting block 81, the fixing sleeve 7 is directly slipped onto the surface of the mounting block 81 from the top. During this process, the fixing sleeve 7 will press the retaining tooth 84 back into the groove 82 along the inclined surface of the retaining tooth 84. When the square hole 71 and the retaining tooth 84 are aligned, the spring 83 will press the retaining tooth 84 into the square hole 71, thereby achieving a fixed connection between the mounting block 81 and the fixing sleeve 7. When it is necessary to separate the mounting block 81 and the fixing sleeve 7, the retaining tooth 84 is pressed apart from the square hole 71, and the fixing sleeve 7 can be removed from the surface of the mounting block 81.

[0030] Working principle: When assembling the bracket, first pull out each inner tube 4 in sequence. Specifically, pull the end plate 63 to separate the insertion rod 62 from the second locking hole 42, and then push the inner tube 4 out of the square tube 1 through the sliding rod 43. During the movement of the inner tube 4, release the end plate 63. When the first locking hole 41 coincides with the insertion rod 62, under the tension of the tension spring 64, the insertion rod 62 will insert into the first locking hole 41, thereby fixing the inner tube 4 to the outside of the square tube 1, thus increasing the support area of ​​the bracket. Next, the two fixing sleeves 7 at the bottom of the gantry frame 2 are respectively fitted onto the mounting blocks 81 on the surface of the two square tubes 1 to fix the gantry frame 2. After use, the gantry frame 2 can be disassembled, and then the inner tube 4 can be slid back into the square tube 1.
