Description

Technical Field

[0001] This utility model belongs to the technical field of valve flanges, and specifically relates to a quick-release valve flange bolt removal device. Background Technology

[0002] Valve flanges are key components in industrial piping systems used to connect valves to pipes or other equipment. They are typically made of metal (such as carbon steel, stainless steel, or alloy steel) and their structure includes an annular disc, bolt holes, and sealing surfaces. Sealing is achieved through bolt tightening, ensuring the safe transport of pipeline media in high-pressure, high-temperature, or corrosive environments. Flange connection methods (such as flat welding, butt welding, or threaded connection) and sealing types (such as raised face and recessed face) can be selected according to operating conditions. They are widely used in petroleum, chemical, power, and water supply industries, and offer advantages in both installation convenience and maintenance.

[0003] Currently, the inability to quickly disassemble and reassemble valve flange bolts leads to a significant reduction in operational efficiency and increased time spent on manual disassembly, especially in emergency repairs or high-risk conditions (such as high-temperature and high-pressure pipelines), which delays the response time. This increases the labor intensity and safety risks for workers, as traditional tools may cause bolt jamming, stripping, or even personnel injury. The sealing surface is easily damaged, and repeated inefficient operations may destroy the flange's sealing performance, causing media leakage, environmental pollution, or equipment failure.

[0027] Example

[0028] Reference Figures 1-4 This embodiment of the present invention provides a quick-release valve flange bolt removal device, comprising:

[0029] The load-bearing mechanism 100 includes a bracket 110, a vertical rod 120 hinged to the center of the inner cavity of the bracket 110, and a support assembly 130 disposed at the bottom of the vertical rod 120.

[0030] The adjustment mechanism 200 includes a fixed block 210 fixedly installed on the outside of the bracket 110, a threaded sleeve 220 fixedly installed on the outside of the fixed block 210, and a bidirectional threaded rod 230 threadedly installed in the inner cavity of the threaded sleeve 220.

[0031] The bracket 110 provides an overall structural frame, the hinged design of the vertical rod 120 allows the device to adapt to the flange angle during operation, avoiding installation difficulties caused by rigid connection, the support component 130 can adapt to flange bolts of different heights, and the bidirectional threaded rod 230 in the adjustment mechanism 200 cooperates with the threaded sleeve 220 to precisely control the clamping force, ensuring a tight fit between the device and the flange during disassembly, reducing the risk of slippage and improving work efficiency.

[0032] Specifically, the adjustment mechanism 200 also includes a connecting shaft 240 fixedly installed at the end of the bidirectional threaded rod 230, a handle 250 fixedly installed on the outside of the connecting shaft 240, and a clamping assembly 260 provided at the bottom of the threaded sleeve 220.

[0033] The adjustment mechanism 200 enables convenient manual operation of the bidirectional threaded rod 230 via the connecting shaft 240 and the lever 250, allowing bolt disassembly and assembly to be completed without the need for power tools. It is suitable for environments without power or explosion-proof environments. The clamping assembly 260 enhances the device's ability to fix the flange edge, prevents the device from shifting during disassembly, ensures that the direction of force is consistent with the bolt axis, and avoids thread damage or tool deformation caused by eccentric force.

[0034] Furthermore, the support assembly 130 includes an adjusting groove rod 131 fixedly installed at the bottom of the vertical rod 120, a slider 132 movably engaged in the inner cavity of the adjusting groove rod 131, a limiting sleeve 133 fixedly installed on the outside of the slider 132 and movably sleeved on the outside of the adjusting groove rod 131, and a placement hole plate 134 fixedly installed on the top of the limiting sleeve 133 for installing and removing the rod. The support assembly 130 also includes a rotating shaft 135 hinged to the outside of the adjusting groove rod 131, a locking rod 136 fixedly installed on the outside of the rotating shaft 135, a magnetic adsorption groove 137 opened on the outside of the adjusting groove rod 131, and an iron block 138 fixedly installed at the end of the locking rod 136, the iron block 138 being movably engaged in the inner cavity of the magnetic adsorption groove 137.

[0035] The adjusting groove rod 131 of the support component 130 cooperates with the slider 132, allowing the limiting sleeve 133 to slide axially along the vertical rod 120, thereby flexibly adjusting the height of the placement plate 134 and adapting to flange bolts of different specifications. The sleeve design of the limiting sleeve 133 enhances the stability of the adjusting groove rod 131 and prevents the support from loosening due to vibration during disassembly. The placement plate 134 can quickly install disassembly rods of different sizes, such as sockets or wrenches, realizing modular replacement of tools and improving versatility. The hinged design of the rotating shaft 135 and the locking rod 136, together with the magnetic adsorption groove 137 and the iron block 138, realizes the quick locking and releasing of the support component 130. When the locking rod 136 rotates to the magnetic adsorption groove 137, the iron block 138 is attracted and fixed, ensuring that the adjusting groove rod 131 remains stable during operation. When adjustment is required, the locking can be released by simply turning the locking rod 136. The operation is simple and does not require additional fasteners, significantly improving disassembly and assembly efficiency.

[0036] Preferably, the clamping assembly 260 includes a vertical plate 261 fixedly mounted on the bottom of the threaded sleeve 220, and a bolt 262 threadedly mounted on the outside of the vertical plate 261. The clamping assembly 260 also includes a clamping rod 263 fixedly mounted on the outside of the vertical plate 261 by the bolt 262, and a limiting protrusion 264 fixedly mounted on the bottom of the clamping rod 263 for clamping the flange edge.

[0037] The clamping assembly 260 features an adjustable clamping structure formed by the vertical plate 261 and bolts 262. Tightening the bolts 262 pushes the clamping rod 263 to press against the flange edge, creating a rigid fixation. This design avoids the problem of unstable clamping caused by uneven flange surfaces in traditional clamps, making it particularly suitable for rusted or coated flanges. The threaded adjustment of the bolts 262 allows for fine-tuning of the clamping force, ensuring the stability of the device while preventing excessive clamping that could deform the flange. The design of the limiting protrusion 264 further optimizes the positioning performance of the clamping assembly 260. Its bottom contour matches the shape of the flange edge, allowing it to automatically engage with the flange's outer edge groove or protrusion, achieving self-centering. The clamping rod 263 is fixed to the vertical plate 261 by the bolts 262. Different specifications of the limiting protrusion 264 can be quickly replaced after disassembly, adapting to various flange standards and significantly expanding the applicability of the device.

[0038] Furthermore, the load-bearing mechanism 100 also includes a knob 140 fixedly installed on the top of the vertical rod 120, and a limiting piece 150 fixedly installed on the outside of the bracket 110.

[0039] The knob 140 is fixed to the top of the vertical rod 120, which facilitates manual rotation to adjust the angle of the support component 130. Together with the limiting plate 150, it constrains the swing range of the vertical rod 120, preventing excessive rotation from causing the device to become unbalanced. The limiting plate 150 also strengthens the structural rigidity of the bracket 110, disperses stress when disassembling high-torque bolts, avoids deformation of the bracket 110, and extends the service life of the device.

[0040] In use, first place the bracket 110 near the flange, and adjust the angle of the vertical rod 120 by the knob 140 to align the support assembly 130 with the bolt position; then slide the limiting sleeve 133 on the adjusting groove rod 131 to a suitable height, use the magnetic adsorption groove 137 to fix the clamping rod 136 in position, and install the matching disassembly tool on the placement hole plate 134; then turn the hand lever 250 to drive the bidirectional threaded rod 230 to rotate, which drives the limiting protrusion 264 of the clamping assembly 260 to clamp the flange edge to achieve a stable fixation; finally, by rotating the support assembly 130, the disassembly tool is used to apply force to the bolt, and the bolt is safely disassembled under the constraint of the limiting piece 150.

[0041] In summary, the bearing mechanism 100 adopts a combination of a hinged vertical rod 120 and an adjustable support assembly 130, which ensures the device's adaptability to flange angles. The adjustment mechanism 200 provides precise clamping force control through the cooperation of a bidirectional threaded rod 230 and a lever 250. Combined with a replaceable clamping assembly 260 with a limiting protrusion 264, it can adapt to flanges of different standards and ensure concentric force application. The coordinated design of the knob 140 and the limiting piece 150 further optimizes operational convenience and structural stability. The mechanically adaptive structure significantly reduces installation difficulty and improves adaptability to complex working conditions such as corroded flanges and confined spaces. The modular design allows a single device to cover the disassembly and assembly needs of flange bolts of various specifications, greatly improving tool utilization. The combination of rigid support and anti-slip structure effectively avoids the eccentric force problem in traditional disassembly, protecting the integrity of bolt threads and improving operational safety, making it particularly suitable for rapid maintenance operations in the petroleum and chemical industries.
