Description

Technical Field

[0001] This invention relates to the field of boiler processing technology, and more specifically to a support device for boiler production. Background Technology

[0002] In boiler manufacturing, the assembly and circumferential welding of the boiler shell are crucial processes. Currently, roller frames and other support devices are commonly used to support the boiler shell for welding operations. In related technologies, these support devices are mostly fixed structures. However, in actual production, boiler products often come in diverse specifications; different models and applications of boilers have significantly different shell diameters. Fixed support structures, due to their inherent structural limitations, are unable to support boiler shells of varying diameters, thus limiting their usability and failing to meet users' daily needs. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a support device for boiler production, which can ensure stable support of the boiler shell during the production process, improve the safety of the production process, and can also adapt to the production of boiler shells of different sizes, thereby improving its versatility and market competitiveness.

The multiple support components are spaced apart on the base frame along the axial direction of the boiler shell. Each support component includes two support arms, which are located on opposite sides of the boiler shell in the radial direction. One end of each support arm is rotatably connected to the base frame, and the other end of each support arm is provided with a roller for abutting against the boiler shell. Each support arm has a linkage gear, and the linkage gears of two adjacent support arms mesh with each other to achieve synchronous rotation. A locking mechanism is provided between the support arm and the base frame to restrict the rotation of the support arm relative to the base frame.

The drive wheel is connected to the output end of the driver, the driven wheel rotates coaxially with the roller, and a drive belt is provided between the drive wheel and the driven wheel.

[0010] In some embodiments, the boiler production support device further includes a tensioning assembly, which includes a tensioning cylinder and two tensioning rods. The tensioning cylinder is disposed on the base frame and has a sliding cavity inside. The tensioning rods have a first end and a second end that are disposed opposite to each other. The first ends of the two tensioning rods are slidably disposed in the sliding cavity. The two tensioning rods move away from each other relative to the tensioning cylinder. A third elastic element is disposed between the first ends of the two tensioning rods, and a tensioning wheel is disposed at the second end of the tensioning rod.

[0012] In some embodiments, the lifting mechanism includes a transmission rod and two hinged connecting rods. The transmission rod has a bidirectional threaded section, and a sliding seat is screwed onto the bidirectional threaded section.

One end of the connecting rod is hinged to the corresponding sliding seat, and the other end of the connecting rod has a ball seat, and the supporting ball is disposed in the ball seat.

[0013] In some embodiments, the base frame further includes a plurality of legs, the bottom of which is provided with anti-slip pads.

[0014] Compared with related technologies, the present invention has at least the following technical effects: through the meshing transmission of the linkage gears between the support arms and the coordinated cooperation of the locking mechanism, it can not only ensure the stable support of the boiler shell during the production process and improve the safety of the production process, but also adapt to the production operation of boiler shells of different sizes, thereby improving its versatility and market competitiveness.

Detailed Implementation

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] like Figures 1 to 5 As shown, an embodiment of the present invention provides a support device for boiler production, which includes a base frame 11 and multiple support components 12. The multiple support components 12 are spaced apart on the base frame 11 along the axial direction of the boiler shell. Each support component 12 includes two support arms 121, which are located on opposite sides of the boiler shell in the radial direction. One end of each support arm 121 is rotatably connected to the base frame 11, and the other end of each support arm 121 is provided with a roller 122 for abutting against the boiler shell. Each support arm 121 has a linkage gear 123, and the linkage gears 123 of two adjacent support arms 121 mesh with each other to achieve synchronous rotation. A locking mechanism 13 is provided between the support arm 121 and the base frame 11 to restrict the rotation of the support arm 121 relative to the base frame 11.

[0023] Specifically, the base frame 11 serves as the fundamental load-bearing structure of the entire device, ensuring that it will not deform or be damaged when subjected to the weight of the boiler shell and various external forces during production. Multiple support components 12 are evenly arranged on the base frame 11 at certain intervals along the axial direction of the boiler shell. This spacing can be flexibly adjusted according to the actual length of the boiler shell and support requirements, ensuring comprehensive and uniform support for the boiler shell while avoiding unnecessary costs and operational complexity due to overly dense support points. In this embodiment, two support components 12 are provided, located at opposite ends of the boiler shell along its axial direction.

[0024] Each support assembly 12 includes two support arms 121, which are located on opposite sides of the boiler shell in the radial direction. This symmetrical layout design enables the support force to be evenly distributed on both sides of the boiler shell, effectively preventing the boiler shell from tilting or deforming due to uneven force during the support process, thereby ensuring the shape accuracy and structural stability of the boiler shell.

[0025] One end of the support arm 121 is rotatably connected to the base frame 11, giving the support arm 121 a certain degree of freedom of movement. This allows it to be flexibly adjusted according to the actual installation position and angle of the boiler shell, better conforming to the surface of the boiler shell and providing precise support. The other end of the support arm 121 is equipped with a roller 122, which makes good contact with the outer surface of the boiler shell, providing stable support while reducing wear on the boiler shell surface. When the boiler shell needs to move axially during production, the roller 122 can roll smoothly, greatly reducing friction during movement and making operation easier and more convenient.

[0026] Optionally, the roller 122 can be made of high-strength alloy steel, which has high wear resistance and load-bearing capacity, and is suitable for supporting heavy boiler shells.

[0027] The linkage gears 123 of two adjacent support arms 121 mesh with each other, forming a tight transmission system. When one support arm 121 is subjected to an external force and rotates, the adjacent support arms 121 will rotate synchronously through the meshing transmission of the linkage gears 123, thereby achieving synchronous action of all support arms 121. This synchronous rotation design ensures that when supporting the boiler shell, each support point can simultaneously adjust its support angle and force, keeping the boiler shell in a stable state. This avoids the problem of excessive or insufficient local force caused by inconsistent action of each support point, further improving the stability and reliability of the support.

[0028] In addition, a locking mechanism 13 is provided between the support arm 121 and the base frame 11. The function of the locking mechanism 13 is to restrict the rotation of the support arm 121 relative to the base frame 11 after the support arm 121 is adjusted to a suitable position and angle, and to fix the support arm 121 in the current state, so as to prevent the support arm 121 from rotating unexpectedly due to vibration or other external forces during boiler production, thereby ensuring the stability and safety of the support.

[0029] In summary, the present invention, through the meshing transmission of the linkage gears 123 between the support arms 121 and the coordinated cooperation of the locking mechanism 13, can not only ensure the stable support of the boiler shell during the production process and improve the safety of the production process, but also adapt to the production operation of boiler shells of different sizes, thereby improving its versatility and market competitiveness.

[0030] In this embodiment, the base frame 11 includes multiple crossbeams 111 and multiple longitudinal beams 112. The crossbeams 111 and longitudinal beams 112 are assembled to form a frame structure, thereby creating a stable supporting foundation. Figure 1 As shown, beam 111 along Figure 1 As shown, the longitudinal beam 112 extends in the left and right directions. Figure 1 The front-to-back extension setting is shown.

[0031] Furthermore, the base frame 11 includes multiple fixed seats 113, which are mounted on the longitudinal beam 112. The fixed seats 113 are arranged in a one-to-one correspondence with the support arms 121. The fixed seats 113 are provided with rotating shafts, and the support arms 121 are rotatably connected to the rotating shafts to realize the rotation of the support arms 121 relative to the base frame 11.

[0032] Furthermore, the base frame 11 also includes multiple legs 114 arranged in an array, with anti-slip pads on the bottom of each leg 114. The anti-slip pads can be made of materials with good elasticity and friction properties, such as rubber or silicone.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the locking mechanism 13 includes a mounting base 131, a locking tooth 132, and a ratchet 133. The mounting base 131 is disposed on the base frame 11. The locking tooth 132 is rotatably connected to the mounting base 131. A first elastic element 134 is provided between the mounting base 131 and the locking tooth 132. The ratchet 133 rotates synchronously with the linkage gear 123. The locking tooth 132 is used to abut against the ratchet on the ratchet 133 to limit the unidirectional rotation of the ratchet 133.

[0034] Specifically, the mounting base 131 provides a stable mounting position for the locking teeth 132. The locking teeth 132 and the mounting base 131 are assembled together by a rotatable connection, allowing the locking teeth 132 to rotate freely within a certain range, thereby achieving effective engagement and release of the ratchet 133. The front end of the locking teeth 132 is set as a sharp wedge shape so that it can accurately engage between the ratchet teeth of the ratchet 133, providing a reliable locking effect. The rear end of the locking teeth 132 is connected to the first elastic element 134, and the rotation position of the locking teeth 132 is controlled by the force of the first elastic element 134. The ratchet 133 and the linkage gear 123 rotate synchronously, that is, the two are connected by means of gear meshing, chain drive, belt drive, or coaxial connection.

[0035] Furthermore, the first elastic element 134 can be configured as a spring. When the locking tooth 132 is subjected to an external force and rotates, the first elastic element 134 will be compressed or twisted, generating elastic potential energy. Once the external force disappears, the first elastic element 134 will release the elastic potential energy, driving the locking tooth 132 to quickly return to its initial position. This design allows the locking tooth 132 to automatically reset, always maintaining engagement with the ratchet 133, ensuring the reliability of the locking mechanism 13.

[0036] Furthermore, the tooth profile of the ratchet 133 is a unidirectional helical tooth, which allows the locking tooth 132 to be lifted and slide over the back of the tooth under the pressure of the first elastic element 134, allowing the support arm 121 to rotate freely in the direction of reducing the support diameter. After the support arm 121 is adjusted, it can be locked by the engagement of the locking tooth 132 and the ratchet 133, ensuring stable support for the boiler shell.

[0037] In some embodiments, the locking mechanism 13 further includes a movable rod 135. The base frame 11 is provided with a movable hole, and the movable rod 135 is movably inserted into the movable hole. The movable rod 135 is connected to the mounting base 131. A second elastic element 136 is provided between the movable rod 135 and the base frame 11. When the movable rod 135 is subjected to an externally applied force, the movable rod 135 drives the mounting base 131 to move, the second elastic element 136 deforms, and the mounting base 131 drives the locking tooth 132 to disengage from the ratchet gear 133.

[0038] Specifically, the movable rod 135 is generally slender, cylindrical, or elongated. This shape not only facilitates smooth movement within the movable hole but also reduces friction with the inner wall of the hole, lowering operating resistance. The diameter of the movable hole matches the diameter of the movable rod 135, typically being slightly larger to allow the movable rod 135 to slide freely within it while effectively restricting its direction of movement and preventing deviation or wobbling during movement. The mounting base 131 can be fixed to the movable rod 135, for example, through welding or threaded connection.

[0039] In actual use, when adjustment of the support arm 121 is required, the operator only needs to apply an external force to the moving rod 135. This force can be a manually applied push or pull, or it can be applied through other tools or equipment. After being subjected to external force, the moving rod 135 will move within the movable hole, simultaneously moving the connected mounting base 131. The movement of the mounting base 131 changes the relative position between the locking teeth 132 and the ratchet 133, causing the locking teeth 132 to gradually disengage from the ratchet teeth of the ratchet 133. With the disengagement of the locking teeth 132, the ratchet 133 is no longer restricted by the locking teeth 132 and can rotate freely, thereby driving the linkage gear 123 to rotate, thus enabling the support arm 121 to rotate and adjust relative to the base frame 11.

[0040] During the movement of the moving rod 135, the second elastic element 136 is stretched, generating elastic potential energy. Once the support arm 121 is adjusted to the appropriate position and angle, the operator releases the external force applied to the moving rod 135. At this point, the second elastic element 136 releases its elastic potential energy, driving the moving rod 135 and the mounting base 131 to quickly return to their initial positions. The mounting base 131 then causes the locking teeth 132 to re-engage between the ratchet teeth of the ratchet 133, restoring the one-way locking effect on the ratchet 133, thereby limiting further rotation of the support arm 121 and ensuring that the support arm 121 is stably fixed in its current position.

[0041] Furthermore, the base frame 11 is provided with an abutment seat 116, and the first elastic element 134 is provided between the abutment seat 116 and the moving rod 135.

[0042] Furthermore, the boiler production support device also includes a first linkage rod 137, and the locking mechanism 13 is set one-to-one with the support component 12. The first linkage rod 137 is used to connect the moving rod 135 in the locking mechanism 13 corresponding to two adjacent support components 12 so that the mounting base 131 moves synchronously.

[0043] In other words, each support component 12 is equipped with a locking mechanism 13, ensuring that each support component 12 can independently and accurately achieve locking and unlocking functions. The first linkage rod 137 and the moving rods 135 in the corresponding locking mechanisms 13 of the two adjacent support components 12 are connected in a robust and reliable manner, such as by welding, bolting, or snap-fit. When multiple support components 12 need to be unlocked, the operator only needs to apply an external force to one of the moving rods 135. This force is quickly transmitted to the other adjacent moving rods 135 through the first linkage rod 137. Due to the connecting effect of the first linkage rod 137, each moving rod 135 will simultaneously experience a force in the same direction, thus moving synchronously within its respective movable hole. The synchronous movement of the moving rods 135 drives the connected mounting base 131 to move synchronously, and the mounting base 131 further drives the locking teeth 132 to disengage from the ratchet gear 133. In this way, all locking mechanisms 13 connected to the first linkage rod 137 will unlock simultaneously, allowing the corresponding support components 12 to be adjusted in position simultaneously.

[0044] In some embodiments, the boiler production support device further includes a second linkage rod 124, which is used to connect the linkage gears 123 of the support arms 121 on two adjacent support assemblies 12, so that all support arms 121 are linked synchronously. Figure 1As shown, the second linkage rod 124 extends along the left and right direction of the base frame 11. The second linkage rod 124 enables all support arms 121 to move synchronously, so that the operator does not need to adjust each support arm 121 one by one, which greatly saves operation time and labor costs.

[0045] Furthermore, a first handwheel 125 is provided at the end of the second linkage rod 124. During use, the operator can rotate the handwheel to adjust the support angle formed by the two adjacent support arms 121 to adapt to the placement requirements of boiler shells of different sizes.

[0046] like Figure 2 As shown, in some embodiments, the boiler production support device further includes a drive assembly 14, which includes a driver 141, a driving wheel 142, and a driven wheel 143. The driving wheel 142 is drivenly connected to the output end of the driver 141, and the driven wheel 143 rotates coaxially with the roller 122. A transmission belt 144 is provided between the driving wheel 142 and the driven wheel 143. When the driver 141 is started, its output end begins to rotate, driving the driving wheel 142 to rotate synchronously. The driving wheel 142 transmits rotational power to the driven wheel 143 through the transmission belt. Since the driven wheel 143 rotates coaxially with the roller 122, the roller 122 also rotates accordingly. The rotation of the roller 122 drives the boiler shell on the entire support device to rotate, achieving support and adjustment for different parts of the boiler.

[0047] Alternatively, the driver 141 can be configured as a motor, hydraulic motor, or other component.

[0048] Furthermore, there are two driving wheels and two driven wheels. The two driven wheels are correspondingly mounted on the rollers in the two support components, and the driving wheel and the driven wheel are arranged in a one-to-one correspondence. The drive component also includes a drive rod 145, which extends along the left-right direction of the base frame. The drive rod 145 is located at the output end of the driver, and the driving wheel is mounted on the drive rod, realizing the synchronous rotation of the rollers on the two support components.

[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the support device for boiler production further includes a tensioning assembly 15. The tensioning assembly 15 includes a tensioning cylinder 151 and two tensioning rods 152. The tensioning cylinder 151 is disposed on the base frame 11 and has a sliding cavity 1511 inside. The tensioning rods 152 have a first end 1521 and a second end 1522 disposed opposite to each other. The first ends 1521 of the two tensioning rods 152 are slidably disposed in the sliding cavity 1511. The two tensioning rods 152 move away from each other relative to the tensioning cylinder 151. A third elastic element 153 is provided between the first ends 1521 of the two tensioning rods 152. The second ends 1522 of the tensioning rods 152 are provided with a tensioning wheel 154.

[0050] Specifically, the tensioning cylinder 151 can be directly fixed to the base frame 11, or it can be fixed to the base frame 11 via the support rod 155 to achieve the installation and fixation of the tensioning assembly 15. During the normal operation of the support device for boiler production, the transmission belt will gradually loosen due to factors such as long-term use, temperature changes, or load changes. When the transmission belt loosens, the third elastic element 153 will use its own elastic force to push the first ends 1521 of the two tensioning rods 152 to move in opposite directions within the sliding cavity 1511. As the tensioning rods 152 move, the tensioning wheel 154 installed at the second end 1522 of the tensioning rods 152 will also move accordingly. The tensioning wheel 154 will press tightly against the transmission belt, increasing the tension of the transmission belt and restoring the transmission belt to a suitable tension state.

[0051] When the drive belt becomes too tight for some reason, it exerts a reverse force on the tensioning pulley 154. This force is transmitted to the third elastic element 153 through the tensioning rod 152, causing the third elastic element 153 to undergo a certain degree of compression deformation. This relieves the excessive tightness of the drive belt and prevents it from being damaged due to overstretching. Through this dynamic adjustment mechanism, the tensioning assembly 15 can always maintain the drive belt at its optimal tension, ensuring the stable operation of the transmission system.

[0052] like Figure 1 and Figure 5 As shown, in some embodiments, the boiler production support device further includes multiple side support components 16, and multiple side support components 12 are arranged on opposite sides of the base frame 11 along the radial direction of the boiler shell; the side support component 12 includes a lifting mechanism 161 and a support ball 162, the lifting mechanism 161 drives the support ball 162 to move in the vertical direction of the base frame 11, and the support ball 162 is used to abut against the side wall of the boiler shell.

[0053] Specifically, multiple side support components 16 are arranged on opposite sides of the base frame 11 along the radial direction of the boiler shell, and abut against the boiler shell via support rollers 162, thus forming a symmetrical and stable support structure with the support components 12, ensuring the placement stability of the boiler shell. During actual operation, the lifting mechanism 161 moves the support rollers 162 flexibly up and down along the base frame 11 according to a preset program. When the boiler shell is placed on the support device, the lifting mechanism 161 quickly activates, raising the support rollers 162 to a suitable height, so that they are tightly abutted against the side wall of the boiler shell. At this time, the support rollers 162 act like stable fulcrums, providing reliable support for the boiler shell and ensuring that the boiler shell can be stably placed on the support device.

[0054] Furthermore, as the boiler shell rotates driven by the drive assembly 14, multiple side support assemblies 16 form a dynamic support system through the close contact between the support rollers 162 and the side wall of the boiler shell. The support rollers 162 can roll freely as the boiler shell rotates, always maintaining good contact with the side wall of the boiler shell, and adjusting the direction and magnitude of the support force in a timely manner to prevent the boiler shell from shifting or shaking.

[0055] Furthermore, the lifting mechanism 161 includes a transmission rod 163 and two hinged connecting rods 164. The transmission rod 163 has a bidirectional threaded section 1631, and a sliding seat 165 is screwed onto the bidirectional threaded section 1631. The base frame 11 has a guide groove, and the sliding seat 165 has a slider 1651 that matches the guide groove. The connecting rods 164 and the sliding seats 165 are arranged in a one-to-one correspondence. One end of the connecting rod 164 is hinged to the corresponding sliding seat 165, and the other end of the connecting rod 164 has a ball seat 1641. The supporting ball 162 is disposed in the ball seat 1641, thereby forming a scissor-type support linkage mechanism. When the two sliding seats 165 move towards or away from each other, the unfolding angle of the connecting rod 164 can be changed, thereby realizing the height adjustment of the supporting ball 162, so that it can accurately abut against the outer wall of the boiler shell with different diameters.

[0056] In the transmission rod 163, the bidirectional threaded section 1631 can be divided into a first threaded section, a limiting section, and a second threaded section. The threads on the first threaded section and the second threaded section have opposite directions of rotation. The limiting section is located between the first threaded section and the second threaded section to limit the travel of the sliding seat.

[0057] Furthermore, a second handwheel 166 is provided at the end of the transmission rod 163, allowing the operator to adjust the height of the supporting ball 162 by rotating the handwheel. Of course, in some embodiments, the transmission rod 163 may also be connected to a drive component such as a motor or hydraulic motor.

[0058] In this embodiment, two side support components 16 are provided, and the two side support components 12 are arranged on opposite sides of the base frame 11 along the radial direction of the boiler shell. In use, the operator can support the boiler shell through the support components 12 located at both ends of the base frame 11 in the left and right directions, and then adjust the height of the support ball 162 by the second handwheel 166 so that it can reliably abut against the outer wall of the boiler shell, thereby fixing the boiler shell.
