Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and in particular to a winch box structure, a winch, a winch platform and a winch platform installation method. Background Art

[0002] In the field of oil drilling, with the continuous advancement of technology and the increase in the demand for deep well drilling, the performance requirements for winches are getting higher and higher. Although the traditional AC variable frequency electric drive winch is quite mature in the application of 90DB and below, with diverse configurations and relatively stable technology, its design and manufacturing face new challenges when facing the demand for winches of a larger level. Especially for ultra-deep well drilling rigs, due to the complex operating environment and harsh working conditions, higher requirements are placed on the structural strength, stability and ease of operation of the winch.

[0003] There are two main layouts of disc brakes on the market: side-mounted single disc and front-mounted double disc, each with its own advantages and disadvantages. Although the side-mounted single disc layout is easy to install and maintain and will not be affected by the wire rope lubricant, it will take up more space for the winch length; while the front-mounted double disc layout can ensure that the drum shaft is balanced, but it requires increasing the distance between the left and right wall panels, which will also affect the overall size. In addition, neither of these two layouts solves the problem of transportation difficulties caused by the large structure of large winches.

[0004] Therefore, the development of a new winch platform has become one of the urgent problems to be solved in the industry. The new platform aims to overcome the shortcomings of the existing technology through optimized design, such as improving integration to reduce volume, enhancing load-bearing capacity to ensure safety, simplifying operation procedures to improve efficiency, etc. Specifically, the winch platform proposed in the present invention adopts a unique special-shaped frame structure and a slot-type plug-in plate design, which not only makes the entire equipment more compact and lightweight, easy to transport and quickly deploy, but also ensures sufficient strength and stability. In addition, the integrated disc brake hydraulic station further improves the brake response speed and reliability, providing strong support for deep well drilling operations. Summary of the invention

[0005] The present invention aims to overcome the above-mentioned shortcomings of the prior art and provides a winch box structure, a winch, a winch platform and a winch platform installation method.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A winch box structure includes: a box body, the box body includes a back plate and at least two parallel wall plates, the back plate is arranged between the two wall plates, a drum shaft is rotatably arranged between the two wall plates, and installation gaps for installing a disc brake device are formed between the back plate and the two wall plates.

[0008] Furthermore, an opening is formed on the wall panel, and the wall panel is provided with an inserting plate and at least two connecting plates, the inserting plate can be inserted into the opening, the inserting plate is arranged between the two connecting plates and connected to the two connecting plates, the inserting plate is detachably connected to the wall panel through the connecting plates, and after the inserting plate is installed, a mounting hole matching the roller shaft is formed with the wall panel;

[0009] Both ends of the plug board abutting against the wall board are formed with first buckling parts along the insertion direction of the plug board, and one end of the connecting plate is formed with a second buckling part, and the first buckling part can be buckled with the second buckling part to connect the plug board and the connecting plate.

[0010] Furthermore, a third snap-fitting portion is formed at the edge of the opening of the wall panel along the direction of insertion of the plug plate, and a fourth snap-fitting portion is formed at one end of the connecting plate away from the second snap-fitting portion, and the third snap-fitting portion can be snap-fitted with the fourth snap-fitting portion to connect the wall panel to the connecting plate.

[0011] Furthermore, the wall panel is provided with a plurality of first connection holes, and the connection plate is provided with a plurality of second connection holes, and the first connection holes can correspond one-to-one with the second connection holes for installing bolts and fixing the connection plate and the wall panel.

[0012] Furthermore, it also includes a crossbeam, which is arranged across two wall panels.

[0013] Furthermore, it also includes a first mounting plate and a second mounting plate, both of which are located on the same side of the back plate, the first mounting plate is installed on the beam and faces the mounting gap, and the second mounting plate is used to be installed on the base and is located outside the mounting gap.

[0014] Furthermore, it comprises: a winch box structure, a drum shaft and a disc brake device.

[0015] Furthermore, it comprises: a base, on which a motor, a reduction box, a disc brake hydraulic station and the above-mentioned winch are installed.

[0016] Furthermore, the base includes a first installation area and a second installation area, and the first installation area and the second installation area are separated on both sides of the center line of the base. The winch and the disc brake hydraulic station are installed in the first installation area, and the motor mounting seat and the reduction gearbox mounting seat are installed side by side in the second installation area.

[0017] Furthermore, a method for installing a winch platform comprises the following steps:

[0018] S1: Install the winch and the disc brake hydraulic station in the first installation area of ​​the base, so that the center line of the winch drum is on the geometric center plane of the box, and the winch structure is arranged symmetrically;

[0021] 1. Compact structure, easy to transport and install: The center line of the winch drum is placed on the geometric center plane of the box, so that the two main motors can be placed on the same side, thus effectively shortening the length of the winch. This design not only reduces the footprint of the equipment, but also reduces the difficulty and cost of transportation and installation.

This is especially important for deep well drilling operations that require frequent starts and stops or emergency braking. The installation gap between the back panel and the wall panel is reasonably designed, which not only ensures the effective clamping of the disc brake device, but also avoids the contamination of the brake system by the wire rope lubricant, ensuring stable and reliable braking performance.

[0023] 3. Enhanced structural strength and stability: The special-shaped frame structure and reinforcement plate reinforcement design make the entire box have higher torsional strength and stability, and can withstand greater working loads and harsh working conditions. This is crucial for ultra-deep well drilling rigs, as they need to operate stably for a long time in extreme environments. The slot-type plug-in plate not only enhances the load-bearing capacity of the wall panel, but also simplifies the installation process of the drum shaft, reduces the risk of loose components caused by vibration, and improves the overall reliability of the equipment.

[0024] 4. Optimize maintenance and service life: The integrated design concept makes the layout of key components (such as disc brake hydraulic station, reduction box, motor, etc.) more reasonable, which is convenient for daily inspection and maintenance. This not only reduces downtime, but also extends the service life of the equipment. Through reasonable layout and material selection, the noise and vibration level of the equipment during operation is reduced, the working environment is improved, and the comfort and safety of the operator are improved.

[0025] In summary, the winch platform of the present invention achieves the goals of compact structure, efficient operation, safety and reliability through a number of innovative designs, and provides a more advanced and practical solution for the oil drilling industry.

[0034] Specific Examples

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] In this embodiment, if Figure 1 , 2 As shown, a winch box body includes: a box body 1, the box body 1 includes a back plate 11 and at least two parallel wall panels 12, the back plate 11 is arranged between the two wall panels 12, the drum shaft 4 is rotatably arranged between the two wall panels 12, and an installation gap 13 for installing a disc brake device 5 is formed between the back plate 11 and the two wall panels 12.

[0038] Specifically, the back plate 11 is arranged between the two wall panels 12, and an equidistant installation gap 13 is left at both ends. The installation gap 13 allows the disc brake device 5 to extend to the back of the box 17. At the same time, the brake caliper 52 is arranged on the back of the box 17, which significantly improves the brake response time, making the braking faster and more accurate, thereby improving the working efficiency and safety. This is particularly important for deep well drilling operations that require frequent starting and stopping or emergency braking. The installation gap 13 between the back plate 11 and the wall panel 12 is reasonably designed, which not only ensures the effective clamping of the disc brake device 5, but also avoids the contamination of the brake system by the wire rope lubricant, ensuring the stability and reliability of the braking performance. In addition, the disc brake device 5 is installed on the back of the back plate 11, and there is no need to increase the distance between the two wall panels 12, thereby ensuring the strength of the winch box.

[0039] This design enables the brake caliper 52 to conveniently clamp the disc brake device 5 for braking, thereby improving braking efficiency and safety.

[0040] Further, an opening is formed on the wall panel 12, and the wall panel 12 is provided with an inserting plate 2 and at least two connecting plates 3, the inserting plate 2 can be inserted into the opening, the inserting plate 2 is arranged between the two connecting plates 3 and connected to the two connecting plates 3, the inserting plate 2 is detachably connected to the wall panel 12 through the connecting plates 3, and after the inserting plate 2 is installed, it forms a mounting hole 15 matching the roller shaft 4 with the wall panel 12;

[0041] Both ends of the plug board 2 abutting against the wall board 12 are formed with first buckling parts 21 along the insertion direction of the plug board 2, and one end of the connecting plate 3 is formed with a second buckling part 31. The first buckling part 21 can be buckled with the second buckling part 31 to connect the plug board 2 and the connecting plate 3.

[0042] Specifically, Figure 6 As shown, the mounting hole 15 extends out of the wall plate 12 in the horizontal direction to form a U-shaped groove. When installing or removing the drum shaft 4, the mounting hole 15 is inserted through the U-shaped groove. The plug plate 2 matches the drum shaft 4 on the side connected to the drum shaft 4, and a complete circular mounting hole 15 is formed after insertion.

[0043] Since the winch is subjected to the upward pulling force of the fast rope during operation, this force acting on the wall panel 12 will eventually be borne by the notch, so it is necessary to increase the strength of the notch.

[0044] Furthermore, a third snap-fitting portion 121 is formed at the edge of the opening of the wall panel 12 along the direction of insertion of the plug plate 2, and a fourth snap-fitting portion 32 is formed at the end of the connecting plate 3 away from the second snap-fitting portion 31. The third snap-fitting portion 121 can be snap-fitted with the fourth snap-fitting portion 32 to connect the wall panel 12 to the connecting plate 3.

[0045] Specifically, the corresponding positions of the plug board 2 and the wall board 12 are provided with a connecting plate 3, the connecting plate 3 is provided as a "concave" strip, and the two protrusions are respectively a second buckling portion 31 and a fourth buckling portion 32, and the corresponding positions of the plug board 2 and the wall board 12 are provided with a third buckling portion 121 and a first buckling portion 21, and the third buckling portion 121 and the first buckling portion 21 are combined to match the "concave" strip of the connecting plate 3, and the positioning strip on one side of the plug board 2 is fixed to the "concave" strip. When installing, the positioning strip on one side of the wall board 12 is inserted into the other end of the "concave" strip to achieve sliding installation;

[0046] The design of the slot-type plug-in plate 2 simplifies the disassembly and assembly process of the roller shaft 4 and its related components, making daily maintenance more convenient and quick.

[0047] Furthermore, a plurality of first connection holes are provided on the wall panel 12, and a plurality of second connection holes are provided on the connection plate 3. The first connection holes can correspond one to one with the second connection holes, and are used to install bolts and fix the connection plate 3 and the wall panel 12.

[0048] In the above structure, after installation, bolts and spring washers are used to fix, and the bolts are inserted into the connection holes at the corresponding positions of the "concave" strip and the wall panel 12 to achieve fixation;

[0049] Furthermore, it also includes a cross beam 14 , which is arranged across the two wall panels 12 .

[0050] Specifically, the upper parts of the two wall panels 12 are connected by a crossbeam 14, and a rotating shaft is set at the center of the roller shaft 4. The length of the rotating shaft matches the interval between the two wall panels 12 and is installed between the two wall panels 12;

[0051] Furthermore, it also includes a first mounting plate 16 and a second mounting plate 101, both of which are located on the same side of the back plate 11, the first mounting plate 16 is installed on the beam 14 and faces the mounting gap 13, and the second mounting plate 101 is used to be installed on the base 10 and is located outside the mounting gap 13.

[0052] The mounting plate is used to install the disc brake device 5 of the winch, so that the main part of the brake caliper 52 is exposed to the outside, which is convenient for the installation and maintenance of the brake caliper 52; because the disc brake device 5 is subjected to force when the winch brakes, the fixing point of the disc brake device 5 is particularly important. The mounting plate is fixed to the corresponding positions of the cross beam 14 and the base 10 with reinforced profiles, which is convenient for positioning when installing the disc brake device 5 and enhancing the structural strength.

[0053] Furthermore, it comprises: a winch box 17 structure, a drum shaft 4 and a disc brake device 5.

[0054] Specifically, the upper parts of the two wall panels 12 are connected by a crossbeam 14, and a rotating shaft is set at the center of the roller shaft 4. The length of the rotating shaft matches the interval between the two wall panels 12 and is installed between the two wall panels 12;

[0055] The disc brake device 5 includes a brake disc 51 and a brake caliper 52. The brake disc 51 is installed on the drum shaft. The height of the beam 14 matches the diameter of the brake disc 51. The brake caliper 52 is set on the mounting plate of the base 10 and the beam 14, and clamps the brake disc 51 to realize the winch braking function.

[0056] This design enables the center line of the drum shaft 4 to be located on the geometric center plane of the box body 17, thereby shortening the length of the winch and improving the space utilization efficiency.

[0057] Furthermore, it comprises: a base 10, on which a motor 8, a reduction box 7, a disc brake hydraulic station 6 and a winch are installed.

[0058] Furthermore, the base 10 includes a first installation area and a second installation area, and the first installation area and the second installation area are separated on both sides of the center line of the base 10. The winch and the disc brake hydraulic station 6 are installed in the first installation area, and the motor 8 mounting seat and the reduction box 7 mounting seat are installed side by side in the second installation area.

[0059] Specifically, the base 10 is divided into two parts along the center line of the base 10, the winch and the disc brake hydraulic station 6 are installed in the first installation area, and the motor 8 mounting seat and the reduction box 7 mounting seat are installed side by side in the second installation area. The motor 8 is set as a double motor 8, which drives the winch, and the disc brake hydraulic station 6 is pre-buried on the base 10. The hydraulic pipeline enters the inside of the base 10 and is finally connected to the brake caliper 52. The integrated hydraulic station can control the length of the hydraulic pipeline within 4 meters, and control the pipe loss pressure to a large extent.

[0060] It also includes a control box, and a control box mounting plate is welded on the back plate 11 for mounting the winch control box. The control box is mounted on the back of the winch, which is also conducive to electrical, hydraulic and gas wiring.

[0061] Placing the center line of the winch drum on the geometric center plane of the box 17 allows the two main motors 8 to be placed on the same side, thereby effectively shortening the length of the winch. The design of the integrated disc brake hydraulic station 6 enables the brake system to respond in a very short time, effectively reducing the risks that may occur in emergency situations.

[0062] Furthermore, a method for installing a winch platform comprises the following steps:

[0063] S1: Install the winch and the disc brake hydraulic station 6 in the first installation area of ​​the base 10, so that the center line of the winch drum is on the geometric center plane of the box 17, and the winch structure is arranged symmetrically;

[0064] S2: Install the disc brake hydraulic station 6, the reduction box 7 and the motor 8 side by side in the first installation area, so that the devices installed in the first installation area are arranged symmetrically with the devices installed in the second installation area;

[0065] S3: Connect the disc brake hydraulic station 6, the reduction box 7 and the motor 8 to the corresponding power supply and control system.

[0066] Specifically: a solid foundation is selected, and the base 10 is fixed by high-strength bolts or welding to prevent displacement caused by vibration or heavy load.

[0067] The disc brake hydraulic station 6, the reduction box 7, the motor 8 and the brake caliper 52 are sequentially arranged on the base 10;

[0068] Each component should be placed accurately according to the design drawings to ensure that the connection between them is tight and easy to disassemble. For heavy components such as reduction box 7 and motor 8, a crane should be used for handling.

[0069] Make the center line of the winch drum on the geometric center plane of the box 17, and the winch structure is arranged symmetrically;

[0070] The double motor 8 is designed side by side, which can make the most of the winch width space. This layout can also center the winch's center of gravity, making it easier to hoist the winch as a whole.

[0071] S2: Installation of the box 17: The wall panels 12 are installed on the base 10, the cross beams 14 are arranged on the upper ends of the wall panels 12, a plurality of wall panels 12 are connected and fixed, and the back panel 11 is fixed between the base 10 and the cross beams 14, and an installation gap 13 is left between the back panel 11 and the wall panel 12;

[0072] Use high-precision tools to measure and adjust the position of the back plate 11 to ensure that the gap between it and the wall plate 12 meets the design requirements. Use high-strength fasteners to fix the back plate 11 to ensure that it will not deform under high loads. Provide enough space for installing the disc brake device 5 and enhance the overall strength of the box body 17.

[0073] Insert the drum shaft 4 into the wall plate 12 through the U-shaped groove, connect one end of the drum shaft 4 to the reduction box 7, and at the same time, the disc brake device 5 extends out of the installation gap 13 to correspond to the position of the brake caliper 52;

[0074] Apply a proper amount of lubricating oil on the roller shaft 4 to reduce friction and protect the surface. Use a special tool to push the roller shaft 4 smoothly into the U-shaped groove until the disc brake device 5 extends correctly. Simplify the installation process of the roller shaft 4 and improve assembly efficiency.

[0075] Adjust the position of the drum shaft 4 and make sure that the brake caliper 52 is aligned with the brake disc 51 to ensure the braking function;

[0076] The disc brake device 5 is placed in the middle of the jaws of the brake caliper 52, so that the brake caliper 52 can effectively clamp the disc brake device 5 when it is closed, thereby achieving the braking function.

[0077] Install the plug board 2 and fix it through the connecting plate 3;

[0078] Choose a suitable material for the plug plate 2, such as high-strength alloy steel, to improve wear resistance and corrosion resistance. Use a torque wrench to tighten the fixing screws according to the specified torque value to ensure that the plug plate 2 is firm but not over-tightened to avoid affecting the free rotation of the roller shaft 4. Enhance the bearing capacity of the wall panel 12 while ensuring the smooth rotation of the roller shaft 4.

[0079] Check and confirm that the brake caliper 52 is correctly installed on the base 10 and aligned with the disc brake device 5;

[0080] Before installation, perform a comprehensive inspection on the brake caliper 52 to ensure that there is no damage or wear. Use a laser alignment instrument or other precision instruments to calibrate the position of the brake caliper 52 to ensure that it is perfectly aligned with the brake disc 51. Ensure the effective operation of the brake system and improve braking performance and safety.

[0081] Connect the disc brake hydraulic station 6, the reduction box 7 and the motor 8 to the corresponding power supply and control system;

[0082] Use high-quality cables and connectors to ensure the reliability of electrical connections. Perform multiple test runs to check that all connections are correct and adjust parameters to achieve optimal performance. Implement linkage control of various systems to improve operational convenience and response speed.

[0083] Furthermore, a method for using a winch platform comprises the following steps:

[0084] Start the motor 8, drive the drum shaft 4 to rotate through the motor 8-reduction box 7, and start the winch operation;

[0085] Before the initial start-up, perform a comprehensive safety check, including a functional test of the emergency stop button. Slowly increase the speed of the motor 8, observe the rotation of the drum shaft 4 and the noise level, and ensure that everything is normal before gradually accelerating to operating speed. Verify that the entire system functions properly and ensure that the winch can be started and operated smoothly.

[0086] When braking is required, the disc brake hydraulic station 6 is activated to control the brake caliper 52 to clamp the disc brake device 5 to achieve deceleration or stop operation;

[0087] Check the pressure and flow of the hydraulic system regularly to ensure that it is within the normal range. Train operators to be familiar with the braking procedures so that they can respond quickly in emergency situations.

[0088] After use, turn off all power supplies and perform necessary cleaning and maintenance.

[0089] Develop a detailed maintenance plan, including daily inspections, scheduled maintenance, and annual overhauls. Record the content and results of each maintenance to track the historical performance of the equipment.

[0090] Furthermore, two disc brake devices 5 are provided, which are respectively arranged on both sides of the drum shaft.

[0091] Specifically, two disc brake devices 5 are arranged between the two wall panels 12, respectively close to the wall panels 12 on both sides, and the middle part of the drum shaft 4 is used for winding the steel rope;

[0092] The double disc brake device 5 design enhances the reliability and safety of the brake system, ensuring rapid and effective braking in emergency situations.

[0093] Furthermore, a lubricating oil circuit is provided at the position of the base 10 corresponding to the reduction box 7 .

[0094] The internal space of the winch base 10 is used as the winch lubricating oil tank. The oil tank is composed of 6 cavities connected through each other, among which the A oil pump flange and the B oil pump flange are the oil suction ports, and the B oil return flange and the A oil return flange are the oil return ports. By optimizing the oil circuit layout, the return oil of the reduction box 7 circulates in the oil tank for one circle before entering the oil suction chamber, which can effectively utilize the self-heating function of the oil tank to cool the return oil of the reduction box 77.

[0095] Furthermore, a reinforcing plate 9 is provided at the connection between the wall panel 12 and the base 10 and the cross beam 14 .

[0096] like Figure 6 As shown, the reinforcing plate 9 is arranged in the cross beam 14 and at the connection between the wall panel 12, the base 10 and the cross beam 14. The reinforcing plate 9 can increase the contact area between the cross beam 14 and the wall panel 12, and further improve the stability of the box 17. Specific implementation: The wall panel 12 is fixed as a whole by the design of the cross beam 14, and the reinforcing plate 9 of the back panel 11 and the wall panel 12 is supported and strengthened, and the whole box 17 is welded into a firm box-shaped structure, which improves and ensures the structural strength of the box 17.
