[0002] Hazardous chemical transport vehicles are special vehicles designed for transporting chemicals with hazardous properties such as explosiveness, flammability, toxicity, corrosiveness, and radioactivity. The tanks of these vehicles are typically made of relatively thin metals such as stainless steel, carbon steel, or aluminum alloy. The tanks have openings for various media filling and discharging pipelines. These pipelines bear significant loads during use, placing high demands on the strength of the tank flanges; therefore, a flange reinforcement process is required for the tank flanges.

[0003] Existing flanging processes include manual pry bar method and die pulling method. Among them, the manual pry bar method is difficult to control the roundness, height and depth of the flanging, resulting in poor flanging quality and low efficiency; the die pulling method generally requires two people to operate, one outside the tank and one inside, which is not economically efficient.

[0025] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0026] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0027] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0028] This application provides a flanging device, mainly used for flanging openings on a tank body.

[0029] The tank body has openings, which can be various functional holes. Specifically, the tank body includes a cylindrical body and end caps located at opposite ends of the cylindrical body, with the openings located on the cylindrical body.

[0030] Combination Figure 1 and Figure 2The flanging device 1 includes a support mechanism, a movable lifting mechanism 12, and a flanging mechanism 13. The support mechanism includes support members 11 spaced laterally for supporting a horizontal tank 2; the support mechanism allows the tank 2 to rotate about its own axis. The movable lifting mechanism 12 is capable of moving longitudinally between the laterally spaced support members 11 and can be raised and lowered. The flanging mechanism 13 is mounted on the movable lifting mechanism 12 and moves and rises and falls with the movable lifting mechanism 12. The flanging mechanism 13 includes an outer mold 131, a telescopic member 133, and an inner mold 132. The telescopic member 133 includes a fixed end and a lifting end that can be raised and lowered relative to the fixed end. The fixed end is connected and fixed to the outer mold 131, and the lifting end is detachably connected to the inner mold 132 and can lower the inner mold 132 to at least partially within the outer mold 131. The outer mold 131 is located outside the tank 2 and abuts against the tank 2, while the inner mold 132 is located inside the tank 2. The inner mold 132 can act downwards so that the periphery of the opening in the tank 2 forms a reinforcing ring under the combined action of the outer mold 131 and the inner mold 132.

[0031] That is, the flanging device 1 supports the tank body 2 through a support mechanism, and the flanging mechanism 13 is moved and raised / lowered through a moving lifting mechanism 12. The flanging mechanism 13 then performs the flanging operation on the openings on the tank body 2. The operation is simple, allowing for single-person operation and improving flanging efficiency. The cooperation between the outer mold 131 and the inner mold 132 improves the accuracy of the roundness, height, and depth of the reinforced shape after flanging, enhancing the overall quality and significantly strengthening the flange of the tank body 2.

[0032] Specifically, the support mechanism includes at least two sets of support components spaced longitudinally, each set of support components including two support members 11 spaced laterally, with multiple support members 11 jointly supporting a tank body 2. In this embodiment, the number of support components is two sets, i.e., four support members 11 arranged in a 2×2 configuration. In other embodiments, the number of support components can also be three sets, arranged in a 3×2 configuration. The specific configuration depends on the actual situation.

[0033] See Figure 3 The support member 11 includes a support base 111 and a roller 112 disposed on the top of the support base 111. The axis of the roller 112 extends longitudinally, and the roller 112 is rotatable relative to the support base 111.

[0034] The support base 111 has two ear plates fixed at intervals, and the two ear plates are rotatably connected to the roller 112 through a rotating shaft.

[0035] In the two support members 11 arranged laterally opposite each other, at least one roller 112 is connected to a rotation drive member 128113 to drive the roller 112 to rotate. In each support assembly, after one roller 112 rotates through the drive member 128, the tank 2 located on that roller 112 rotates, which in turn drives the other roller 112 to rotate, thereby achieving smooth rotation of the tank 2. Of course, each roller 112 can also be connected to a corresponding drive member 128.

[0036] In this embodiment, the bottom of the support base 111 is also provided with a reinforcing structure to increase the strength of the bottom of the support base 111.

[0037] The movable lifting mechanism 12 can move longitudinally between the horizontally spaced support members 11 and can rise and fall. The movable lifting mechanism 12 moves longitudinally, allowing it to move to different positions to perform hole-flipping operations on the openings at different axial length positions on the tank body 2.

[0038] Combination Figures 4-6 The mobile lifting mechanism 12 includes a base frame 121, rollers 122 disposed at the bottom of the base frame 121, a lifting assembly disposed on the base frame 121, and a support plate 129 disposed at the top of the lifting assembly. The lifting assembly can drive the support plate 129 to rise and fall relative to the base frame 121. The support plate 129 is used to connect with the flange mechanism 13.

[0039] The base frame 121 includes two parallel longitudinal beams and a crossbeam connecting the two longitudinal beams. In this embodiment, there are two crossbeams, which are spaced apart along the longitudinal direction.

[0040] The base frame 121 has four rollers 122 at its bottom. Specifically, the rollers 122 are located at the bottom of the longitudinal beams. Two rollers 122 are spaced apart on each longitudinal beam. The moving lifting mechanism 12 moves by moving the rollers 122.

[0041] The roller 122 is driven by a power assembly. Specifically, the power assembly includes a motor 123, a sprocket 124, a chain 125, and a cross brace 126. The cross brace 126 extends laterally, with a roller 122 connected to each end. A sprocket 124 is fitted around the outer periphery of the cross brace 126, and another sprocket 124 is fitted onto the output shaft of the motor 123. The chain 125 is looped around the two sprockets 124. Therefore, when the motor 123 starts, it drives the cross brace 126 to rotate through the sprockets 124 and the chain 125, thereby realizing the rolling of the roller 122.

[0042] The lifting assembly includes at least two connecting rod assemblies 127 arranged laterally at intervals. In this embodiment, there are two connecting rod assemblies 127, each corresponding to one of the two longitudinal beams.

[0043] The link 127 assembly includes two cross-connected links 127, which are hinged together at their midpoints. The bottom end of each link 127 is hinged to the base frame 121, and the top end is hinged to the support plate 129. The link 127 is capable of sliding longitudinally relative to the support plate 129. That is, the sliding direction of the link 127 is longitudinal.

[0044] Specifically, the bottom of the support plate 129 is provided with a sliding groove that extends longitudinally, and a pulley is hinged to the top of the connecting rod 127, which slides within the sliding groove. In this embodiment, the bottom of the support plate 129 is provided with an inwardly opening U-shaped member, and the U-shaped member contains a sliding groove.

[0045] The lifting assembly includes a drive member 128, which is connected to a connecting rod 127. The top end of the driving connecting rod 127 slides relative to the support plate 129, thereby causing the support plate 129 to rise or fall relative to the base frame 121.

[0046] In this embodiment, the driving component 128 is a hydraulic cylinder, which is inclined and connected to the connecting rod 127 via a crossbar. The crossbar extends laterally and is connected to a connecting rod 127 at each end, thereby synchronously driving the two connecting rod 127 assemblies to move.

[0047] The lifting assembly and the power assembly are arranged longitudinally along the base frame 121.

[0048] A through hole is provided in the middle of the support plate 129. Multiple bolt holes are provided on the support plate 129 at intervals, and the multiple bolt holes are arranged around the outer periphery of the through hole.

[0049] Combination Figure 7 and Figure 8 The flange mechanism 13 includes a base 134, a connecting shaft 135, and a telescopic member 133. The base 134 is connected to the movable lifting mechanism 12. Specifically, the base 134 is connected to the support plate 129 to achieve the connection with the movable lifting mechanism 12.

[0050] The base 134 has a through hole running vertically through it. Specifically, the base 134 includes a bottom plate and a top plate arranged in parallel intervals, and multiple stiffening plates connecting the top plate and the top plate. Both the top plate and the bottom plate are annular plates with a central opening, and the multiple stiffening plates are arranged circumferentially. The top plate, the bottom plate, and the multiple stiffening plates together form the through hole. This through hole is located in the center of the base 134.

[0051] The radial dimension of each stiffening slab gradually increases from top to bottom.

[0052] The base plate has multiple connection holes, which correspond to the multiple bolt holes on the support plate 129. The base plate and the support plate 129 are connected by fasteners.

[0053] The top of the base 134 is connected to the outer mold 131. Specifically, the base 134 and the outer mold 131 are connected by fasteners.

[0054] The outer mold 131 is cylindrical. The top of the outer mold 131 is open, and a through hole is formed in the center of the bottom. Specifically, the outer mold 131 includes a cylindrical body and an annular plate disposed at the bottom of the cylindrical body, with a through hole formed in the center of the annular plate. The through hole and the through-hole are correspondingly arranged.

[0055] The ring plate has multiple fixing holes, which are spaced apart circumferentially. The top plate of the base 134 has multiple mounting holes, which correspond to the fixing holes. The ring plate and the top plate are connected by fasteners passing through the fixing blocks and mounting holes, thereby connecting the base 134 and the outer mold 131.

[0056] The perforation on the ring plate communicates with the through hole on the base 134. Ideally, the size of the perforation should match the size of the through hole.

[0057] The telescopic component 133 includes a fixed end and a lifting end that can rise and fall relative to the fixed end. The fixed end is connected and fixed to the base 134. Specifically, the telescopic component 133 is a hydraulic cylinder, including a cylinder body and a piston rod that moves relative to the cylinder body. The cylinder body is connected to the bottom of the top plate of the base 134 via a fixed plate, thereby realizing the connection between the telescopic component 133 and the base 134. The piston rod can move relative to the cylinder body. Both the cylinder body and the piston rod extend vertically, thereby enabling the piston rod to rise and fall. That is, the cylinder body constitutes the fixed end. The top end of the piston rod constitutes the lifting end.

[0058] The bottom of the telescopic member 133 extends downward beyond the base 134 and passes through a through hole in the support plate 129 of the movable lifting mechanism 12.

[0059] The connecting shaft 135 connects the inner mold 132 and the lifting end of the telescopic member 133, and can lift the inner mold 132 relative to the outer mold 131. Specifically, the connecting shaft 135 can pass through the through hole and the lifting end can pass through the through hole and the lifting end, so that the inner mold 132 can lift within the through hole and the lifting end.

[0060] The connecting shaft 135 has a receiving groove with a bottom opening, and the lifting end extends into the receiving groove and is screwed into the connecting shaft 135. Specifically, the inner circumferential wall of the receiving groove is provided with threads, and the outer circumference of the lifting end is provided with threads to realize the screw connection between the two, thereby realizing a detachable connection.

[0061] The inner mold 132 includes an upper cylindrical section 1321, a lower cylindrical section 1322 disposed at the bottom of the upper cylindrical section 1321, and a sleeve 1323 disposed within the upper cylindrical section 1321. The upper cylindrical section 1321 is cylindrical, and the lower cylindrical section 1322 gradually narrows in diameter from top to bottom. In this embodiment, the angle between the outer peripheral wall of the lower cylindrical section 1322 and the vertical direction is less than 45 degrees.

[0062] An annular plate is provided between the bottom of the lower cylinder section 1322 and the sleeve 1323, so that the sleeve 1323 is located inside the lower cylinder section 1322. The top of the sleeve 1323 is flush with the top of the upper cylinder section 1321. The bottom of the sleeve 1323 is connected to the annular plate.

[0063] The sleeve 1323 is hollow inside, and the connecting shaft 135 passes through the sleeve 1323 and is fixedly connected to the sleeve 1323.

[0064] Specifically, the connecting shaft 135 extends upward beyond the sleeve 1323. The bottom of the connecting shaft 135 is flush with the bottom of the ring plate.

[0065] The flange device 1 includes a longitudinally extending track 15, which is located between two transversely spaced support members 11. The movable lifting mechanism 12 can move along the track 15. The movement of the movable lifting mechanism 12 on the track 15 not only ensures smooth movement but also ensures the correct direction of movement.

[0066] Furthermore, the base frame 121 is also equipped with an oil reservoir, a pump, and pipelines to provide hydraulic oil to the drive component 128 and the telescopic component 133 of the lifting assembly. The oil reservoir, pump, and pipelines are arranged longitudinally at intervals from the lifting assembly and laterally at intervals from the motor 123.

[0067] The flange device 1 is used as follows: The tank 2 is hoisted onto the support mechanism, which supports the tank 2. Then, the drive roller 112 is rotated to rotate the opening on the tank 2 that needs to be flanged to the bottom.

[0068] The lifting mechanism 12 is activated, moving it to the opening to be flanged. The flange mechanism 13 is raised by operating the lifting assembly, so that the top of the outer mold 131 abuts against the bottom of the tank body 2.

[0069] Next, the inner mold 132 and the connecting shaft 135 are placed together inside the tank 2 and passed through the opening so that the connecting shaft 135 is screwed to the lifting end of the telescopic component 133.

[0070] Operate the telescopic component 133 to lower the lifting end, which in turn lowers the inner mold 132. During the descent, the inner mold 132 overcomes the material yield force and works together with the outer mold 131 to form a regular and consistent reinforcing ring around the opening of the tank body 2.

[0071] After flanging one opening, the inner mold 132 is raised, and the connection between the inner mold 132 and the telescopic component 133 is released. The inner mold 132 is then removed from the tank body 2. The lifting assembly then descends, causing the outer mold 131 to detach from the tank body 2. Finally, the lifting mechanism 12 continues to move to the next opening for flanging. Furthermore, when the opening is not at the bottom of the tank body 2, the supporting mechanism is rotated to bring the opening requiring flanging to the bottom.

[0072] In summary, this flanging device has the following advantages: This flanging device supports the tank body via a support mechanism and moves and lifts the flanging mechanism via a lifting mechanism. The flanging operation, including the opening, is achieved through the cooperation of the outer mold, telescopic component, and inner mold. It is simple to operate, can be performed by a single person, and improves flanging efficiency. The cooperation between the outer and inner molds improves the accuracy of the reinforced roundness, height, and depth after flanging, resulting in higher overall quality and significantly enhancing the reinforcement of the tank flange.

[0073] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
