Description

Technical Field

[0001] The invention relates to the technical field of boiler welding, in particular to a biomass boiler component processing and welding device. Background Art

[0002] A biomass boiler is a boiler that uses biomass energy as fuel. A double-drum biomass boiler is a type of biomass boiler. A double-drum biomass boiler adopts a vertical double-drum type. During the production of a double-drum biomass boiler, multiple rows of convection tubes need to be welded to the upper and lower drums. The multiple rows of convection tubes are of different lengths and are symmetrically distributed. Laser welding equipment is usually used for welding, and the welding of each convection tube to the drum is divided into two sections. First, a preliminary welding connection is made and then the remaining unwelded parts are welded.

[0003] Usually, when welding convection tubes, first align the upper and lower drums, and hoist the upper drum above the lower drum, then three workers cooperate with each other to weld and install the convection tubes between the upper and lower drums one by one. Specifically: one worker aligns the convection tubes at the specified position, then another worker needs to preliminarily weld the top of the convection tube to the upper drum, and the third worker preliminarily welds the bottom of the convection tube to the lower drum. After completing the preliminary installation of the convection tubes, the workers weld the unwelded positions to complete the overall welding process.

[0004] However, when the convection tubes are welded in the above-mentioned welding method, the overall welding efficiency and quality are easily affected by human factors such as the cooperation between the workers and the stability of the operation. In addition, in the process of welding multiple convection tubes, the workers need to adjust the operating position from time to time to facilitate the welding operation, which increases the work intensity of the workers. At the same time, since the upper drum is always in a hoisting state during the entire convection tube installation process, the upper drum is prone to position deviation from the lower drum, which in turn affects the accuracy of the convection tube welding position.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] like Figure 1As shown, a biomass boiler component processing and welding equipment includes a support frame 1, on which two front-to-back symmetrical clamping and pushing mechanisms 6 are arranged for equidistantly distributing convection tubes, a displacement mechanism 7 for driving the clamping and pushing mechanism 6 to move left and right, and a limiting mechanism 4 for assisting the clamping and pushing mechanism 6 to distribute the convection tubes at equal intervals are arranged, the limiting mechanism 4 is arranged on the displacement mechanism 7, and an automatic welding machine 8 is arranged on the limiting mechanism 4; the welding equipment also includes a distance adjustment mechanism 5 for cooperating with the clamping and pushing mechanism 6 to transport the convection tube to the welding position, and the distance adjustment mechanism 5 is arranged on the displacement mechanism 7. It should be noted that the automatic welding machine 8 is an existing automatic laser welding equipment, which uses a laser beam to implement the welding operation between the convection tube and the boiler drum.

[0037] like Figure 2 As shown, a positioning mechanism 2 is arranged on the right side of the upper surface of the support frame 1, and the positioning mechanism 2 includes an adjusting member 21 arranged on the upper surface of the support frame 1, and two groups of left-right symmetrical positioning members 22 are arranged on the adjusting member 21 for aligning the upper and lower boiler drums in the vertical direction. The number of the positioning members 22 in each group is two and they are symmetrical front to back.

[0038] like Figure 2 , Figure 4 and Figure 5 As shown, the adjusting member 21 includes a placing platform 212 fixedly connected to the upper surface of the supporting frame 1, and two left-right symmetrical transmission boxes 214 are fixedly connected at the middle position of the lower surface of the placing platform 212, and the front and rear sides of the transmission box 214 are rotatably connected with an adjusting screw 213, one end of the adjusting screw 213 is rotatably connected to the placing platform 212, and a transmission shaft 215 is penetrated and rotatably connected between the two transmission boxes 214, and the other end of the adjusting screw 213 penetrates into the interior of the transmission box 214 and is connected to the transmission shaft 215 through a bevel gear set. The left end of the placing platform 212 is fixedly installed with a first driving motor 211, and the output shaft of the first driving motor 211 is fixedly connected to the left end of the transmission shaft 215.

[0039] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the positioning member 22 includes a plurality of second limit blocks 223 slidably connected to the upper surface of the placement platform 212, and the plurality of second limit blocks 223 correspond to the plurality of adjusting screws 213 one by one and are threadedly connected. The two second limit blocks 223 corresponding to the front and rear are fixedly connected to the opposite back surfaces of the two second limit blocks 223, and the first limit blocks 222 are fixedly connected to the opposite surfaces of the two clamping rods 221 corresponding to the front and rear near the upper end position, and arc grooves are provided on the opposite surfaces of the two clamping rods 221 corresponding to the front and rear at the positions of the upper and lower drums, and the top of the clamping rod 221 is fixedly connected to the connecting cross plate 224, and the upper surface of the connecting cross plate 224 is fixedly installed with an elastic telescopic electromagnet group 225, and the lower surface of the connecting cross plate 224 is fixedly installed with an elastic telescopic pressing seat 226. It should be noted that the elastic telescopic electromagnet group 225 is an existing device that uses the principle of electromagnets to achieve a telescopic function, and the device combines electromagnets and mechanical elastic elements.

[0040] During specific use, the lower boiler drum is first hoisted to a suitable position on the upper surface of the placement platform 212 by an external hoisting device. A stopper for temporarily limiting the lower boiler drum is provided in the middle of the upper end surface of the placement platform 212 (the stopper is shown in the figure). Then, after the upper boiler drum is hoisted to a suitable position above the lower boiler drum by the external hoisting device, the external hoisting device is kept stationary. At this time, the first drive motor 211 drives the adjusting screw 213 to rotate on the transmission box 214 through the transmission shaft 215 and the bevel gear set. The second limit block 223 threadedly connected to the adjusting screw 213 slides along the placement platform 212 toward the lower boiler drum as the adjusting screw 213 rotates, and at the same time drives the clamping rod 221 to move synchronously until the upper and lower arc grooves on the clamping rod 221 are respectively attached to the outer circumferential surfaces of the upper and lower boiler drums.

[0041] At this time, the first limit block 222 abuts against the lower side of the outer circumferential surface of the upper drum, and during the movement of the clamping rod 221, the elastic telescopic pressing seat 226 gradually shrinks and presses on the upper side of the circumferential surface of the upper drum during the synchronous movement, cooperating with the first limit block 222 to limit the upper and lower positions of the upper drum. At this time, the two elastic telescopic electromagnet groups 225 are in contact with each other, and the two elastic telescopic electromagnet groups 225 are energized and attracted together, so that the top ends of the two clamping rods 221 remain fixedly connected, thereby making the relative position between the upper and lower drums more stable. In addition, since the elastic telescopic electromagnet groups 225 are elastically telescopic, the contact between the two elastic telescopic electromagnet groups 225 can be ensured to be closer, so that the two elastic telescopic electromagnet groups 225 can be stably attracted together.

[0042] like Figure 1 , Figure 6 and Figure 7As shown, two displacement mechanisms 7 are symmetrically arranged front and back, and the displacement mechanism 7 includes a sliding seat 71 slidably connected to the support frame 1 left and right, and the upper surface of the sliding seat 71 is fixedly connected to two support frames 72 symmetrical front and back, and the inner side of the support frame 1 is rotatably connected to a transmission screw 73, and a second drive motor 74 is fixedly installed on the left side of the support frame 1, and the output shaft of the second drive motor 74 is fixedly connected to the left end of the transmission screw 73, and the right end of the transmission screw 73 is rotatably connected to the support frame 1, and the bottom end of the sliding seat 71 is located on the inner side of the support frame 1 and is threadedly connected to the transmission screw 73.

[0043] like Figure 7 and Figure 8 As shown, the limiting mechanisms 4 are arranged on the opposite sides of the two displacement mechanisms 7, and the limiting mechanisms 4 include two left-right symmetrical bidirectional hydraulic telescopic cylinders 41 fixedly connected to the displacement mechanism 7, and the upper and lower ends of the bidirectional hydraulic telescopic cylinders 41 are fixedly connected with connecting plates 42, and the two connecting plates 42 corresponding to the left and right are commonly fixedly connected with a limiting baffle 43, and the opposite surfaces of the two upper and lower corresponding limiting baffles 43 are fixedly connected with a second baffle 45, and the second baffle 45 is hinged with a first baffle 44 on one side close to the supporting frame 1, and a return spring (the return spring is not shown in the figure) is arranged between the first baffle 44 and the second baffle 45, and the automatic welding machine 8 is slidably installed on the opposite back surfaces of the two upper and lower corresponding limiting baffles 43.

[0044] like Figure 1 , Figure 6 and Fig.10 As shown, the upper surface of the support frame 1 is provided with two front-to-rear symmetrical reset mechanisms 3. Taking the reset mechanism 3 on the rear side as an example, the reset mechanism 3 includes two left-right symmetrical support uprights 31 fixedly connected to the upper surface of the support frame 1. The support uprights 31 are located on the side of the limit baffle 43 close to the center of the support frame 1. The limit baffle 43 is located on the side of the support frame 72 close to the center of the support frame 1. Two upper and lower distributed clamping sleeves 34 are clamped on the support uprights 31. The clamping sleeves 34 are fixed to the support uprights 31 by fastening bolts. The rear surfaces of the two corresponding left and right clamping sleeves 34 are commonly fixedly connected to the limiting cross brace 33. The right end of the limiting cross brace 33 is fixedly connected with a reset adjusting rod 32. The right ends of the two upper and lower corresponding reset adjusting rods 32 are inclined in the direction away from each other and at the same time inclined in the direction close to the center of the support frame 1.

[0045] During specific use, while placing the upper and lower drums, the staff can pre-arrange and clamp the convection tubes. First, the bidirectional hydraulic telescopic cylinder 41 extends through the connecting piece 42 to drive the upper and lower second baffles 45 to move away from each other, so that the distance between the upper and lower second baffles 45 is slightly larger than the length of the convection tubes to be stacked. At the same time, the relative distance between the two limiting horizontal braces 33 on the supporting vertical rod 31 is synchronously adjusted according to the position of the second baffles 45. First, the first baffle 44 is rotated on the second baffle 45 so that the first baffle 44 changes from a horizontal state to a vertical state, and then the limiting horizontal brace 33 is adjusted. 3 is moved to the side of the corresponding first baffle 44 close to the center of the support frame 1. After the adjustment is completed, the limiting cross brace 33 is fixed on the support vertical rod 31 through the clamping sleeve 34 and the fastening bolt. At this time, the limiting cross brace 33 can limit the state of the first baffle 44, so that the first baffle 44 and the second baffle 45 remain in a mutually perpendicular state, and the return spring between the first baffle 44 and the second baffle 45 is in a contracted state. After the adjustment of the position of the second baffle 45 is completed, the position of the clamping and pushing mechanism 6 is adjusted, and then the pre-arrangement clamping of the convection tube is completed by the clamping and pushing mechanism 6.

[0046] like Figure 8 and Fig. 9 As shown, taking the clamping and pushing mechanism 6 on the front side as an example, the clamping and pushing mechanism 6 includes a pushing member 62 arranged on the support frame 72, and a clamping member 61 for clamping the convection tube is arranged on the front side of the pushing member 62. The clamping member 61 includes a fixed slide 611 fixedly connected to the pushing member 62, and the fixed slide 611 is located between the corresponding upper and lower limit baffles 43. The front end of the fixed slide 611 is slidably connected to a T-shaped mounting slide 615 left and right, and the front surface of the fixed slide 611 is fixedly connected to a plurality of uniformly distributed first arc clamping blocks 612 The front surface of the T-shaped mounting slide 615 and the left side of the first arc surface clamping block 612 are fixedly connected with the second arc surface clamping block 613, and the arc surfaces of the first arc surface clamping block 612 and the second arc surface clamping block 613 are provided with rubber pads, and the upper and lower surfaces of the right end of the fixed slide 611 are fixedly connected with the first one-way hydraulic telescopic cylinder 614, and the telescopic end of the first one-way hydraulic telescopic cylinder 614 is fixedly connected to the left end of the T-shaped mounting slide 615, and the front surface of the T-shaped mounting slide 615 is slidably connected to the rear surface of the first arc surface clamping block 612.

[0047] During specific use, when adjusting the position of the clamping and pushing mechanism 6, the first one-way hydraulic telescopic cylinder 614 is first extended to drive the T-shaped mounting slide 615 to move to the right on the fixed slide 611, so that the distance between the second arc surface clamping block 613 and its corresponding first arc surface clamping block 612 is increased to slightly larger than the diameter of the convection tube. At this time, the pre-arrangement and placement of a row of convection tubes on the rear side begins. The staff takes the convection tube and first extends the top end of the convection tube to the rear side of the upper first baffle 44, and then places the bottom end of the convection tube on the rear side of the lower first baffle 44. At this time, the convection tube is placed between the arc surfaces of the adjacent first arc surface clamping block 612 and the second arc surface clamping block 613.

[0048] At this time, the upper and lower first baffles 44 and the second baffle 45 and the fixed slide 611 cooperate to limit the front and rear directions of the convection tube, and cooperate with the first arc clamping block 612 and the second arc clamping block 613 to limit the left and right directions of the convection tube. After the staff has placed the convection tube, there is no need to limit the convection tube for a second time, making the loading work easier. The arrangement and placement of the remaining rows of convection tubes are completed according to the above operations.

[0049] When all the convection tubes are placed, the T-shaped mounting slide 615 performs the first stage of contraction. At this time, the arc surfaces of the first arc clamping block 612 and the second arc clamping block 613 on both sides of the convection tube slightly fit the outer wall of the convection tube, so that the convection tube is basically vertical. Then, the upper and lower second baffles 45 are contracted by the two-way hydraulic telescopic cylinder 41 to adjust the upper and lower positions of the convection tube in the center. In the process of moving the two second baffles 45, it is convenient to adjust the upper and lower positions of the convection tube, so that the upper and lower second baffles 45 are respectively fitted to the upper and lower ends of the convection tube. Then, the T-shaped mounting slide 615 performs the second stage of contraction. The first arc clamping block 612 and the second arc clamping block 613 clamp the convection tube. With the rubber protective pad, the first arc clamping block 612 and the second arc clamping block 613 can clamp the convection tube more firmly. At this time, the pre-arrangement and clamping work of the convection tube is completed.

[0050] like Figure 1 and Fig.11 As shown, two groups of distance adjustment mechanisms 5 symmetrically arranged on the opposite sides of the two displacement mechanisms 7 are provided. The distance adjustment mechanism 5 includes a pushing member 51 jointly arranged between a fixed slide 611 and its corresponding upper and lower limit baffles 43. A distance limiting rod 53 is arranged on the pushing member 51. The upper surface of the fixed slide 611 is fixedly connected to a limiting sleeve 52 corresponding to the position of the distance limiting rod 53. The distance limiting rod 53 slides back and forth and passes through the limiting sleeve 52.

[0051] like Fig.11As shown, the pushing member 51 includes a fixed transverse plate 515 fixedly connected to the opposite side of the fixed slide 611, the upper surface of the fixed transverse plate 515 is fixedly connected to a gate-shaped connecting frame 511, and a connecting sleeve 512 is slidably connected between the two vertical sections of the gate-shaped connecting frame 511, and an inclined adjustment plate 513 is fixedly connected to the lower surface of the connecting sleeve 512, and the lower end of the adjusting plate 513 is inclined in the direction away from the corresponding fixed slide 611, and a telescopic connecting rod 516 is fixedly connected to the bottom end of the adjusting plate 513, and one end of the telescopic connecting rod 516 close to the corresponding fixed slide 611 is fixedly connected to the lower surface of the limit baffle 43 below, and a stepped slide groove running through the left and right is opened on the adjusting plate 513, and several stepped sections of the stepped slide groove correspond to the installation positions of several rows of convection pipes one by one, and a connecting slide 514 is slidably connected to the inside of the stepped slide groove, and one end of the connecting slide 514 away from the stepped slide groove is fixedly connected to the corresponding distance limiting rod 53.

[0052] In specific use, when the two-way hydraulic telescopic cylinder 41 contracts to adjust the upper and lower positions of the convection tube through the upper and lower second baffles 45, the limit baffle 43 on the lower second baffle 45 synchronously drives the telescopic connecting rod 516 to move, and the telescopic connecting rod 516 drives the adjustment plate 513 to move synchronously to change the relative position between the adjustment plate 513 and the connecting slide 514. When the adjustment plate 513 slides, the connecting slide 514 slides inside the stepped groove on the adjustment plate 513. At this time, the connecting slide 514 slides to different stepped positions and drives The distance limiting rod 53 slides different distances inside the limiting sleeve 52 to adjust the relative distance between the two distance limiting rods 53 set in the front and rear. Since the several step sections of the stepped slide groove on the adjustment plate 513 correspond one-to-one to the installation positions of the several rows of convection tubes, the distance between the opposite surfaces of the two distance limiting rods 53 set in the front and rear is the relative movement distance of the two rows of convection tubes. When the adjustment plate 513 moves up and down, the connecting sleeve 512 slides synchronously on the door-shaped connecting frame 511 to ensure the stability of the adjustment plate 513 when sliding up and down.

[0053] like Figure 8 , Fig. 9 , Fig.11 and Fig.12As shown, the pushing member 62 includes a fixed mounting plate 623 arranged on the opposite side of the fixed slide 611, the fixed mounting plate 623 is fixedly connected to the corresponding support frame 72 and is slidably connected to the corresponding fixed cross plate 515, and a group of connecting slides 622 are slidably connected to the left and right ends of the fixed mounting plate 623, and the number of connecting slides 622 in each group is two and symmetrical up and down, the connecting slides 622 are fixedly connected to the corresponding fixed slide 611, and the two connecting slides 622 in the same group are fixedly connected to a fixed connecting block 621 at one end away from the corresponding fixed slide 611, and the second one-way hydraulic telescopic cylinder 624 is fixedly connected to the opposite back sides of the two fixed mounting plates 623, and the telescopic end of the second one-way hydraulic telescopic cylinder 624 passes through the fixed mounting plate 623 and is fixedly connected to the fixed slide 611.

[0054] like Figure 1-Figure 12As shown, in specific use, after completing the pre-arrangement and clamping of the convection tube, the second drive motor 74 drives the transmission screw 73 to rotate on the support frame 1. During the rotation, the transmission screw 73 drives the sliding seat 71 to slide to the right on the support frame 1, and drives the fixed mounting plate 623 to slide to the right through the support frame 72, so as to push the convection tube on the fixed slide 611 to the specified position. When the fixed slide 611 slides to the right, it drives the second baffle 45 to move synchronously. At this time, the first baffle 44 slides in contact with its corresponding limit cross brace 33. When the first baffle 44 is separated from the limit cross brace 33, the limit cross brace 33 no longer blocks the first baffle 44. The plate 44 is limited. Since a return spring is arranged between the first baffle plate 44 and the second baffle plate 45, under the action of the return force of the return spring, the first baffle plate 44 rotates on the second baffle plate 45 in the direction away from the two-way hydraulic telescopic cylinder 41. The first baffle plate 44 can be limited by the setting of the limit baffle plate 43, so that the first baffle plate 44 stops rotating after rotating to a horizontal state. When the transmission screw 73 drives the convection tube to move to the installation position, the second unidirectional hydraulic telescopic cylinder 624 is extended to push the convection tube to move in the direction close to the upper and lower drums. At this time, the horizontal first baffle plate 44 no longer limits the convection tube. While the second one-way hydraulic telescopic cylinder 624 drives the fixed slide 611 to move toward each other and push the convection tube, the fixed slide 611 drives the adjustment plate 513, the door-shaped connecting frame 511, the connecting slide 514, and the distance limiting rod 53 to move synchronously through the fixed cross plate 515, and the two corresponding distance limiting rods 53 in the front and rear also move in the direction of approaching each other. After the two corresponding distance limiting rods 53 in the front and rear collide with each other, the convection tube is smoothly moved to the installation position under the clamping drive of the first arc clamping block 612 and the second arc clamping block 613, and then the automatic welding machine 8 on the limiting baffle 43 starts to perform preliminary welding on the end of the convection tube, so that the convection tube is preliminarily positioned at the installation position, which is convenient for subsequent staff to completely weld the convection tube one by one. During the welding process of the staff at the remaining positions, the convection tube will not deviate in position and remain in a vertical state.

[0055] After all the convection tubes have completed the preliminary welding, the first arc surface clamping block 612 and the second arc surface clamping block 613 are released from the convection tubes, and the fixed slide 611 is driven to reset by the second one-way hydraulic telescopic cylinder 624, and then the second drive motor 74 reverses to move the slide seat 71 to the left and restores it to its original position through the transmission screw 73. In the process of the slide seat 71 moving to the left, when the first baffle plate 44 in the horizontal state contacts the reset adjustment rod 32, since the right ends of the two reset adjustment rods 32 arranged up and down are tilted in the direction away from each other and at the same time tilted in the direction close to the center of the support frame 1, first, the right ends of the two reset adjustment rods 32 are tilted in the direction close to the center of the support frame 1, and when the left end of the first baffle plate 44 contacts the right end of the reset adjustment rod 32, the first baffle plate 44 can The first baffle plate 44 is smoothly moved over the right end of the reset adjustment rod 32 and continues to move to the left. At the same time, the right ends of the two reset adjustment rods 32 are tilted in the direction away from each other, so that the first baffle plate 44 can be pushed to rotate on the second baffle plate 45 by the tilted reset adjustment rod 32 in the process of moving to the left over the right end of the reset adjustment rod 32, so that the first baffle plate 44 gradually becomes inclined until it moves to the connection between the reset adjustment rod 32 and the limiting cross brace 33, and the first baffle plate 44 becomes vertical and returns to a state perpendicular to the second baffle plate 45. Subsequently, the first baffle plate 44 continues to move to the left and slides against the limiting cross brace 33, so that the first baffle plate 44 always remains in a vertical state, and the first baffle plate 44 is restored to its original position, and then the above steps are repeated until all convection tubes are welded.
