Description

Technical Field

[0001] This invention relates to the field of oil and gas equipment maintenance technology, and in particular to a pre-elastic wax scraper installation tool and installation method. Background Technology

[0002] During the operation and maintenance of oil storage tanks, wax tends to accumulate on the inner walls. This not only reduces the effective utilization rate of the tank's volume but also accelerates corrosion of the inner walls, affecting the tank's service life and storage efficiency. To ensure the normal operation of the tanks and extend their service life, the inner walls must be cleaned regularly. A common method is to use wax scraping equipment to remove the wax from the inner walls.

[0003] When using a wax scraper to remove wax from the inner wall, the scraper needs to be installed. However, existing scraper installation tools have several shortcomings in application. First, the structure of existing installation tools is relatively complex, requiring significant manpower and time for installation. Second, during installation, existing tools often suffer from inaccurate positioning and insecure fixing, preventing the scraper from achieving optimal performance. Finally, due to the special environment of the tank's inner wall, traditional installation tools are prone to safety hazards during operation, affecting the safety of operators. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a pre-elasticity wax scraper installation tool and installation method that overcomes or at least partially solves the above problems.

[0005] This invention provides a pre-elasticity wax scraping equipment installation tool, including: a main arm, an extension arm rotatably connected to the main arm, an extension arm cylinder connected to the main arm and the extension arm, and a caliper fixing device, a caliper cylinder and a caliper disposed at the end of the extension arm;

[0006] Driven by the caliper cylinder, the caliper fixing device causes the caliper to clamp or release the fixing plate of the wax scraping equipment.

[0007] In some alternative implementations, the caliper fixing device includes a first fixing block mounted at the end of the extender arm, a second fixing block connected to the first fixing block via a caliper cylinder, and a caliper jaw mounted at the end of each fixing block;

[0008] The second fixing block is used to drive the caliper cylinder to clamp or loosen the fixing plate of the wax scraping equipment.

[0009] In some alternative implementations, the length of the extender arm is 1 / 3 to 1 / 2 of the length of the main arm.

[0010] In some optional implementations, a gravity counterweight is also included;

[0011] The gravity counterweight is mounted on the main arm and located at the end where the main arm connects to the extension arm;

[0012] Alternatively, the gravity counterweight can be mounted on the extension arm and located at the end where the extension arm connects to the main arm.

[0013] In some optional implementations, a handguard located at one end of the main arm, the handguard being made of a flexible material, is also included.

[0014] In some optional implementations, it also includes: a detection unit and a control unit;

[0015] The detection unit is used to detect the installation position and height of the wax scraper;

[0016] The control unit is used to control the extension cylinder to extend and retract according to the installation position and height of the wax scraper, so that the caliper is aligned with the fixing plate of the wax scraper; and to control the caliper cylinder to extend and retract so that the caliper clamps the fixing plate of the wax scraper; and to control the extension cylinder to extend and retract so that the extension arm rotates relative to the main arm, thereby driving the fixing plate to move upward through the caliper.

[0017] In some alternative implementations, the control unit is specifically used for:

[0018] Based on the installation position and height of the wax scraper, determine the alignment position and height of the caliper; based on the alignment position and height of the caliper, determine the extension length of the extension cylinder; control the extension of the extension cylinder according to the extension length, so as to control the caliper to move to the alignment position and height to align with the fixing plate of the wax scraper.

[0019] In some optional implementations, the detection unit is also used to monitor the clamping force of the caliper, the angle and displacement of the extension arm in real time; correspondingly, the control unit is also used to adjust the clamping force of the caliper, as well as the angle and displacement of the extension arm, based on the monitoring data of the detection unit.

[0020] The detection unit includes at least one of a pressure sensor, a position sensor, and an angle sensor; the pressure sensor is used to detect the clamping force of the caliper; the position sensor is used to detect the position of the extension arm and the caliper; and the angle sensor is used to detect the rotation angle of the extension arm.

[0021] This invention provides a method for installing a pre-elasticity wax scraper, which is implemented using the aforementioned pre-elasticity wax scraper installation tool.

[0022] In some alternative implementations, the above method includes:

[0023] Move the pre-elastic wax scraper installation tool to the wax scraper installation position;

[0024] Based on the installation position and height of the wax scraper, control the extension and retraction of the arm cylinder to align the caliper with the fixing plate of the wax scraper.

[0025] Control the extension and retraction of the caliper cylinder to clamp the wax scraper mounting plate;

[0026] Controlling the extension arm cylinder to extend and retract causes the extension arm to rotate relative to the main arm. This, in turn, causes the fixed plate to move upward via the caliper, bending the spring plate of the wax scraper and generating a pre-spring force.

[0027] Once the pre-elastic force reaches the preset value, align and securely connect the wax scraper mounting plate and the pre-welded wax scraper adapter.

[0028] After the fixing is completed, control the caliper cylinder to release the fixing plate.

[0029] In some optional implementations, the extension cylinder is controlled to extend and retract according to the installation position and height of the wax scraper, so that the caliper is aligned with the mounting plate of the wax scraper, including:

[0030] The detection unit monitors the installation position and height of the wax scraping equipment.

[0031] Based on the installation position and height of the wax scraper, and the current position and height of the caliper, determine the extension length of the arm cylinder. Control the extension of the arm cylinder according to the determined extension length to align the caliper with the mounting plate of the wax scraper.

[0032] In some optional implementations, controlling the extension cylinder to extend or retract, causing the extension boom to rotate relative to the main boom, includes:

[0033] Based on the current position and target position of the wax scraper mounting plate, determine the rotation angle that the extension arm needs to rotate relative to the main arm. Based on the rotation angle, determine the extension length of the extension arm cylinder. Based on the determined extension length, control the extension of the extension arm cylinder to rotate relative to the main arm by the determined rotation angle.

[0034] The beneficial effects of the above-described technical solutions provided in the embodiments of the present invention include at least the following:

[0035] The pre-elasticity wax scraper installation tool provided in this invention uses an extension cylinder to control the extension arm's movement. The cooperation between the extension arm and the main arm controls the position of the caliper, ensuring it aligns with the wax scraper's mounting plate during installation. The caliper cylinder controls the opening and closing of the caliper, clamping the mounting plate. The extension cylinder then moves the mounting plate to the installation position, causing the wax scraper's spring plate to bend and generate a pre-elastic force. After the mounting plate is connected to the adapter, the caliper cylinder releases the mounting plate. This simple installation tool replaces manual operation, simplifying the installation process, reducing operational difficulty, and improving installation efficiency. The hydraulic system controls alignment, clamping, and release, increasing the automation of wax scraper installation and providing precise control at each stage, improving installation accuracy. The use of this tool also enhances the safety of wax scraper installation, ensuring safe operation.

[0049] To address the problems of inaccurate positioning and insecure fixing in existing pre-elasticity scraping equipment installation tools, and to improve the efficiency and comprehensiveness of tank wall scraping equipment installation, this invention provides a pre-elasticity scraping equipment installation tool. This tool solves the problems of complex structure, inconvenient operation, inaccurate positioning, and insecure fixing in existing installation tools. The tool is rationally designed, easy to use, and effectively improves the installation efficiency and operational stability of the scraping equipment, ensuring smooth cleaning of the tank's inner wall. The following is a detailed description through embodiments.

[0050] This invention provides a pre-elasticity wax scraper installation tool, the structure of which is as follows: Figure 1As shown, it includes: a main arm 2, an extension arm 5 rotatably connected to the main arm, an extension arm cylinder 3 connected to the main arm 2 and the extension arm 5, a caliper fixing device 8, a caliper cylinder 7 and a caliper 6 disposed at the end of the extension arm 5; the caliper fixing device 8, driven by the caliper cylinder 7, drives the caliper 6 to clamp or loosen the fixing plate of the wax scraping equipment.

[0051] The aforementioned pre-elasticity scraper installation tool is generally of an "F" shape, wherein:

[0052] The main arm 2 is the main body of the tool. A hand guard can be installed at one end of the main arm 2, and the other end can be connected to the extension arm 5 and the extension arm cylinder 3. As the main structure of the tool, the main arm 2 connects and supports other components, providing overall stability and support for the tool.

[0053] The boom extension cylinder 3 is located between the main boom 2 and the extension boom 5, and is used to drive the extension and retraction movement of the extension boom 5. (See also...) Figure 1 As shown, the boom cylinder 3 can be located above the main boom 2, and drives the extension and retraction movement of the boom 5 through a hydraulic system to adjust the working length of the tool to adapt to different installation positions and height requirements. The hydraulic system may include cylinders, hydraulic pumps, oil pipes, control valves, and other components.

[0054] The extension arm 5 connects the main arm 2 and the caliper 6, and is used to adjust the position of the caliper 6. The extension arm 5 is also connected to the extension arm cylinder, and can extend and retract under the drive of the extension arm cylinder, thereby adjusting the length of the tool to meet different operating needs and adjusting the caliper 6 to the required position.

[0055] Optionally, the length and ratio of the main boom 2 and the extension boom 5 are carefully designed according to the actual size of the storage tank and the operating range. The length of the main boom 2 is, for example, but not limited to, 1500mm to 2000mm, and the length of the extension boom 5 is 1 / 3 to 1 / 2 of the length of the main boom 2, in order to meet the dual requirements of operational flexibility and structural stability.

[0056] A caliper 6 is located at the end of the extension arm 5 and is used to clamp and secure the fixing plate of the wax scraper. A caliper cylinder 7 drives the opening and closing movement of the caliper 6. The opening and closing of the caliper is controlled by a hydraulic system to achieve precise clamping of the fixing plate, ensuring that the caliper can firmly hold the fixing plate of the wax scraper and can quickly release it when needed. The hydraulic system may include cylinders, hydraulic pumps, oil pipes, control valves, and other components.

[0057] Optionally, the caliper 6 features a V-groove jaw design with an inner surface featuring an anti-slip texture or rubber padding to ensure a secure grip on the wax scraper mounting plate. The caliper's gripping range is designed from 10mm to 50mm to accommodate mounting plates of various thicknesses.

[0058] The caliper fixing device 8 is used to fix the opening and closing state of the caliper 6. Fixing the opening and closing state of the caliper 6 includes fixing the position and angle of the caliper to ensure that the caliper 6 can stably clamp the fixing plate of the wax scraping equipment and ensure that the caliper can maintain a stable clamping state during operation and will not loosen due to vibration or other factors.

[0059] In the aforementioned pre-elasticity wax scraper installation tool, the caliper fixing device 8 includes a first fixing block 81 installed at the end of the extension arm and a second fixing block 82 connected to the first fixing block 81 via a caliper cylinder 7. A caliper jaw 61 is installed at the end of each fixing block. The second fixing block 82 is used to drive the jaw 61 to clamp or release the fixing plate of the wax scraper under the drive of the caliper cylinder 7. The caliper cylinder 7 and the caliper fixing device 8 work together, and the clamping force is precisely controlled by the control unit 20 to prevent damage to the fixing plate during clamping.

[0060] The aforementioned pre-elasticity wax scraper installation tool also includes a gravity counterweight 4. The gravity counterweight 4 is located at the bottom of the tool to balance its center of gravity and increase operational stability. Optionally, the gravity counterweight 4 can be mounted on the main arm 2, located at the end where the main arm 2 connects to the extension arm 5; or, optionally, the gravity counterweight 4 can be mounted on the extension arm 5, located at the end where the extension arm 5 connects to the main arm 2. The installation position of the gravity counterweight 4 is designed according to the tool's counterweight requirements. The weight of the gravity counterweight is set to maintain the balance of the entire tool. The gravity counterweight can be a single piece or multiple pieces, with some or all pieces installed as needed. The gravity counterweight 4 balances and stabilizes the tool, preventing it from tipping or moving during operation, ensuring the tool remains balanced during operation, and ensuring the stability of the installation process.

[0061] The aforementioned pre-elasticity scraping wax installation tool also includes a hand guard 1 located at one end of the main arm. The hand guard 1 is situated on the upper part of the installation tool, at the operating handle, and is used by the operator for gripping. It protects the operator's hands and prevents accidental injury during operation. The hand guard 1 can optionally be made of a flexible material to improve grip comfort.

[0062] The aforementioned pre-elasticity wax scraper installation tool combines a hydraulic system with a mechanical structure. The hydraulic system drives the movement of the extension arm and calipers, enabling precise adjustment and installation of the wax scraper. This tool simplifies the complex installation process of pre-elasticity wax scrapers, significantly reducing the complexity of manual operation. Precise control of the hydraulic system ensures accurate adjustment of the pre-elasticity and installation angle of the wax scraper, improving installation accuracy and stability, and ensuring the effectiveness and lifespan of the wax scraper during use. The use of the hydraulic device replaces traditional manual force application, significantly reducing the labor intensity of operators and lowering work risks. The tool's design also considers safety, with hand guards and gravity counterweights increasing safety during operation and preventing accidental injuries and equipment damage. This tool is suitable for installing various wax scrapers requiring pre-elasticity, has a wide range of applications and significant practical value, greatly improving production efficiency and installation results while increasing operational safety.

[0063] This invention also provides a pre-elasticity scraper installation tool, the structure of which is as follows: Figure 2 As shown, with Figure 1 The difference in the pre-elasticity scraping wax equipment installation tool shown is that the pre-elasticity scraping wax equipment installation tool also includes a detection unit 10 and a control unit 20;

[0064] The detection unit 10 is used to detect the installation position and height of the wax scraping equipment;

[0065] The control unit 20 is used to control the extension cylinder to extend and retract according to the installation position and height of the wax scraper, so that the caliper is aligned with the fixing plate of the wax scraper; and to control the extension cylinder to extend and retract so that the caliper clamps the fixing plate of the wax scraper; and to control the extension cylinder to extend and retract so that the extension arm rotates relative to the main arm, thereby driving the fixing plate to move upward through the caliper.

[0066] Optionally, the control unit 20 is specifically used to determine the alignment position and height of the caliper according to the installation position and height of the wax scraper; determine the extension length of the extension cylinder according to the alignment position and height of the caliper; and control the extension of the extension cylinder according to the extension length to move the caliper to the alignment position and height to align with the fixing plate of the wax scraper.

[0067] The detection unit 10 and control unit 20 can detect the position and height of the wax scraping equipment, thereby enabling automatic alignment of the installation tool, improving the alignment accuracy of the tool, further reducing manual operation, and increasing the degree of automation.

[0068] The detection unit 10 can also monitor the working status of each component in real time, further improving the accuracy and safety of the installation process. Optionally, the detection unit 10 includes at least one of a pressure sensor, a position sensor, and an angle sensor. The pressure sensor is used to detect the clamping force of the caliper; the position sensor is used to detect the position of the extension arm and the caliper; and the angle sensor is used to detect the rotation angle of the extension arm. This allows the detection unit 10 to monitor the clamping force of the caliper 6, the angle and displacement of the extension arm 5, and the overall working status of the tool in real time. For example, the pressure sensor can detect the force applied when the caliper clamps the fixing plate, preventing damage to the fixing plate due to excessive clamping force; the position sensor is used to ensure the accurate positioning of the extension arm and the caliper on the inner wall of the tank.

[0069] The control unit 20, for example but not limited to, employs an embedded control system. Through data interaction with the detection unit 10, it precisely controls the movements of the extension arm cylinder 3 and the caliper cylinder 7, including the range of movement of the extension arm 5, the clamping force of the caliper, and the release action. Specifically, based on real-time data fed back by the detection unit 10, the control unit 20 dynamically adjusts the caliper clamping force to the optimal state, and adjusts the angle and displacement of the extension arm to ensure it is in the appropriate angle and position, preventing loosening or slippage due to torque changes. Simultaneously, it achieves automatic positioning and installation through programmed settings, improving operational efficiency and stability.

[0070] See the usage status of the pre-elasticity wax scraper installation tool. Figure 3 As shown, the pre-elasticity wax scraping equipment installation tool 100 includes a hand guard 1, a main arm 2, an extension cylinder 3, a gravity counterweight 4, an extension arm 5, calipers 6, caliper cylinder 7, and a caliper fixing device 8. The pre-elasticity wax scraping equipment 200 is installed using the pre-elasticity wax scraping equipment installation tool 100. Since the pre-elasticity wax scraping equipment 200 is composed of a fixed plate, a spring plate, and a wax scraping plate from top to bottom, during installation, the two calipers at the upper end of the installation tool 100 clamp the fixed plate of the wax scraping equipment 200. The hydraulic device (e.g., a cylinder, hydraulic pump, etc.) in the middle of the installation tool 100 drives the upper part of the tool and the fixed plate of the wax scraping equipment, bending the spring plate of the wax scraping equipment, causing the fixed plate and the wax scraping plate to bend. Finally, the fixed plate of the wax scraping equipment is connected to the pre-welded wax scraping equipment adapter to complete the installation.

[0071] The tools and methods described in the above embodiments have been described in detail in one part, but will not be elaborated in detail in another part.

[0072] The tool described in this invention simplifies the installation process of the wax scraping equipment, ensuring that the equipment can be quickly and accurately positioned and firmly fixed on the inner wall of the storage tank, thereby improving cleaning efficiency and effectiveness while ensuring operational safety. This pre-elasticized wax scraping equipment installation tool plays a crucial role in storage tank maintenance, significantly improving the installation efficiency and operational stability of the wax scraping equipment, ensuring smooth cleaning of the tank's inner wall, extending the tank's service life, and guaranteeing the safety and efficiency of oil storage and transportation.

[0073] Based on the same inventive concept, embodiments of the present invention provide a method for installing a pre-elasticity wax scraper, which is implemented using the pre-elasticity wax scraper provided in the embodiments of this application. The method flow is as follows: Figure 4 As shown, it includes the following steps:

[0074] Step S101: Preparation of installation tools.

[0075] Move the installation tool to the mounting position of the wax scraper. Ensure the tool is placed on a level surface and stably supported by a counterweight to prevent it from tipping over during operation. Connect the power supply and hydraulic hoses to the hydraulic system, and check the hydraulic oil level and pressure to ensure the system is functioning correctly.

[0076] Step S102: Adjust the main arm and the extension arm.

[0077] Depending on the installation position and height of the wax scraper, adjust the length of the extension arm by controlling the extension and retraction of the extension cylinder to align the caliper with the mounting plate of the wax scraper. Using the control panel of the hydraulic system, activate the extension cylinder to slowly extend or retract the extension arm until the caliper is aligned with the mounting plate of the wax scraper. After confirming the extension arm length is appropriate, lock the extension cylinder to prevent the extension arm from slipping during operation.

[0078] Optionally, control can be achieved through a control unit. The control unit acquires the installation position and height of the wax scraper monitored by the detection unit. Based on the installation position and height of the wax scraper and the current position and height of the caliper, the extension length of the extension cylinder is determined. The extension cylinder is then controlled to extend and retract according to the determined extension length, so that the caliper is aligned with the fixing plate of the wax scraper.

[0079] Step S103: Clamping the fixing plate. Specifically, the extension and retraction of the caliper cylinder can be controlled to clamp the fixing plate of the wax scraping equipment.

[0080] The hydraulic system controls the caliper cylinder, driving the caliper to open and align its ends with the mounting plate of the wax scraper. The operator should carefully align the caliper to ensure it grips the mounting plate smoothly. After aligning the caliper with the mounting plate, slowly close it, ensuring a secure grip and avoiding excessive force that could deform or damage the plate. At this point, the caliper locking mechanism locks the caliper's position and angle, preventing loosening during subsequent operations.

[0081] Optionally, the caliper cylinder can be extended or retracted by the control unit to open and / or close the caliper to clamp the fixing plate.

[0082] Step S104: Apply pre-spring force. Specifically, the extension arm cylinder can be controlled to extend and retract, causing the extension arm to rotate relative to the main arm. This, in turn, causes the fixing plate to move upward via the caliper, bending the spring plate of the wax scraper and generating pre-spring force.

[0083] Activate the boom extension cylinder, which drives the boom upward via the hydraulic system. Simultaneously, this moves the fixing plate of the wax scraper, causing the spring plate of the wax scraper to gradually bend. The operator should carefully observe the bending of the spring plate to ensure it reaches the preset bending angle and spring force value. During the bending process, the boom movement should be smooth and slow to avoid rapid movement that could damage the equipment. When the spring plate reaches the preset angle and spring force value, stop the boom extension cylinder and lock its position to ensure the pre-spring force remains stable.

[0084] Optionally, control can be achieved through a control unit. The control unit determines the rotation angle that the extension arm needs to rotate relative to the main arm based on the current position and target position of the wax scraper mounting plate. Based on the rotation angle, the extension length of the extension arm cylinder is determined. The extension length is then used to control the extension and retraction of the extension arm cylinder, so that the extension arm rotates relative to the main arm by the determined rotation angle.

[0085] Step S105: Fix and install the wax scraping equipment.

[0086] While applying pre-elastic force, align the mounting plate of the wax scraper with the pre-welded wax scraper adapter and secure it with bolts or other fasteners. The operator should ensure that the mounting plate and adapter are firmly connected without loosening or misalignment. This step requires careful inspection of each connection point to ensure that each bolt is tightened and that the mounting plate and adapter surfaces are tightly fitted together.

[0087] Step S106: Release the caliper.

[0088] After installation, the caliper cylinder is controlled via the hydraulic system to slowly open the caliper and release the retaining plate. The operator should ensure the caliper is fully open and the retaining plate is securely fixed to the adapter. After ensuring the caliper is released, remove the tools to avoid unnecessary interference with the wax scraping equipment. Optionally, the caliper cylinder can be controlled via the control unit to open and release the retaining plate.

[0089] Optionally, the above installation method also includes checking and adjusting the installation status of the wax scraper. After the wax scraper is installed, a comprehensive inspection of its installation status should be conducted to ensure that its position and angle are correct. The operator should check that all fasteners are secure, that the connecting surfaces are tightly fitted, and that the wax scraper is in the preset position and angle. If any deviation or looseness is found, adjustments and tightening should be made promptly to ensure that the wax scraper can function properly.

[0090] Optionally, the above installation method also includes maintenance and upkeep of the wax scraping equipment installation tools. After installation, operators should perform regular maintenance and upkeep on the tools. Check the hydraulic oil level and quality of the hydraulic system, and replace or replenish the hydraulic oil as needed. Check the sealing of hydraulic oil pipes and joints to prevent leaks. Inspect and tighten all mechanical connections to ensure their stability and safety. Lubricate the moving parts of the extension arm, main arm, and calipers to reduce wear and resistance, ensuring long-term stable operation of the tool.

[0091] The wax scraping equipment installation tool provided in this embodiment of the invention has at least the following advantages compared with existing wax scraping equipment installation tools:

[0092] 1) It can improve installation efficiency.

[0093] Traditional wax scraping equipment installation often requires a large amount of manual operation, which is cumbersome and time-consuming. The installation tool of this application, through a reasonable mechanism design and a combination of hydraulic system and mechanical structure, greatly simplifies the wax scraping equipment installation process and reduces operational difficulty. Automated clamping and pre-elastic force application significantly improve installation efficiency, reduce installation time, and enhance the overall efficiency of the production line.

[0094] 2) It can improve installation accuracy.

[0095] In existing technologies, manual operation is prone to significant errors, easily leading to inaccurate installation of the wax scraping equipment and thus affecting the wax scraping effect. The installation tool of this application uses a hydraulic system to drive the extension arm and caliper. Through precise control of the extension arm cylinder and caliper cylinder, the length of the extension arm and the clamping force of the caliper can be precisely controlled, enabling the caliper to accurately position and firmly clamp the fixing plate of the wax scraping equipment, ensuring installation accuracy; it also ensures that the pre-spring force and installation angle of the wax scraping equipment meet the preset requirements, improving installation accuracy and stability.

[0096] 3) It can reduce labor intensity.

[0097] Traditional installation methods require manual force application by workers, resulting in high labor intensity and operator fatigue. The installation tool of this application uses a hydraulic device to replace manual force application, significantly reducing the labor intensity of operators, lowering worker fatigue, improving the working environment and conditions, and enhancing operational comfort and safety.

[0098] 4) It can improve security.

[0099] In existing wax scraping equipment installation processes, workers are prone to injury from the equipment and tools, posing significant safety hazards. The use of a caliper fixing device ensures the caliper remains stable when gripping the wax scraping equipment mounting plate, reducing potential accidents during installation and improving operational safety. Furthermore, the installation tool of this application is designed with hand guards and gravity counterweights, effectively protecting the operator's hands, preventing the tool from tipping over or moving, increasing operational safety, and reducing the incidence of workplace injuries.

[0100] 5) Enhance operational stability.

[0101] The tool is equipped with a gravity counterweight, which balances the tool's center of gravity, increases operational stability, and reduces potential shaking and shifting during installation.
