Description

Technical Field

[0001] The invention relates to the technical field of cooking tower construction, in particular to a tower body component spot welding assembly calibration component for a pulping cooking tower. Background Art

[0002] The pulping cooking tower is a key equipment in the pulping process. It is mainly used in the chemical pulping process to break down the lignin macromolecules in the fiber raw materials into small molecules and dissolve them in the liquid medicine through high temperature, high pressure and chemical drugs, so as to dissociate the cellulose and produce qualified pulp.

[0003] Pulping cooking towers can be divided into many types according to different operating methods and structural forms, mainly including intermittent and continuous types. Intermittent cooking towers such as ball cooking towers are suitable for small-scale production, while continuous cooking towers include vertical continuous digesters, horizontal tube continuous digesters, inclined tube continuous digesters, etc., which are suitable for large-scale and continuous production needs.

[0004] The welding workload of the tower components is large, and the geometric dimensions of the assembly welding are high. The welding work must be carried out in accordance with the technical requirements provided by the equipment manufacturer and the corresponding welding process assessment of the technical support personnel;

[0005] In conjunction with the above, it should be noted that: Chinese Patent Publication No. CN117161677A discloses a self-adjusting roller frame for facilitating wind turbine tower welding. The roller frame supports the tower through a support structure, a lifting assembly, and a calibration assembly. After calibration, the servo motor adjusts the ends of the tower to the appropriate height for welding.

[0006] However, the above patent can only perform rolling adjustment of the tower tube for welding processing when it is not assembled. The subsequent assembly of the tower tube still requires secondary spot welding assembly and use, which is similar to the assembly of the cooking tower. The externally installed tower body components still need to be spot welded one by one. Affected by factors such as the tower body height and the installation environment, there are great safety hazards and operational difficulties. Therefore, there is an urgent need to carry out targeted external spot welding processing on the adapter device for building the tower body to reduce the risks of working at high altitude and in high temperature environments.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 - Figure 10 As shown, this embodiment is a tower body component spot welding assembly calibration assembly for a pulping and cooking tower, comprising an assembly base 1, a rotating cylinder center axis 2 being provided on the end face of the assembly base 1, a magnetic disk 103 being embedded on the inner wall of the assembly base 1, and a traction moving assembly 5 and an anti-slip driven assembly 6 being sequentially provided on the side of the magnetic disk 103;

[0035] The traction moving component 5 includes an extension frame 501 and a driving wheel 503, and electromagnetic wheel rings 504 are symmetrically arranged on both sides of the driving wheel 503. The anti-slip driven component 6 includes an adjustment arm rod 601, and the welding adjustment component 3 and the calibration component 4 are respectively arranged at both ends of the top of the assembly base 1.

[0036] The cooking tower is assembled by splicing several tower components. During its assembly, the single-layer main frame of the tower body is installed in advance, and then the remaining tower components are installed one by one. The single-layer main frame of the tower body is a ring structure composed of ring-shaped welded parts.

[0037] like Figure 10 As shown, it is an overall summary framework diagram of the cooking tower. After the single-layer main frame of the middle layer of the tower body is welded, part of the tower body is constructed by manual welding. However, when the outer part is not easy to weld or is in an area with a high risk factor, the angle between the two sets of assembly bases 1 is adjusted according to the outer arc angle of the single-layer main frame by rotating the cylinder center axis 2. At the same time, the adapted welding machine is docked and installed with the welding mounting frame 306. The spot welding assembly calibration component 4 is hoisted to the outside of the single-layer main frame by a hoisting vehicle, and is assisted by personnel inside the single-layer main frame to pull and install the device on the outer wall of the single-layer main frame.

[0038] A transverse cylinder frame 101 is embedded in the top of the assembly base 1, and an energy storage box 102 is recessed in the bottom of the assembly base 1. A lifting cylinder frame 104 is embedded in the middle of the inner wall of the assembly base 1 near the magnetic disk 103, and lifting cylinder frames 105 are symmetrically arranged on both sides of the lifting cylinder frame 104. When the inner wall of the assembly base 1 is close to the outer wall of the single-layer main frame, the lifting cylinder frame 104 and the lifting cylinder frame 2 105 respectively drive the adjustment arm 601 and the extension frame 501 to move. The adjustment arm 601 and the extension frame 501 are both symmetrically arranged on the inner wall of the assembly base 1. The two are pulled away from each other until the distance between the adjustment arm 601 and the extension frame 501 is opened to the maximum, and the personnel inside the tower body pull the assembly base 1 further toward the single-layer main frame until the traction moving component 5 covers the top and bottom surfaces of the single-layer main frame, and the end face of the anti-slip driven component 6 extends over the single-layer main frame.

[0039] One end of the adjusting arm 601 is connected to the lifting cylinder frame 104, and the other end of the adjusting arm 601 is provided with a telescopic arm 602. During the installation of the anti-slip follower component 6, the adjusting arm 601 is driven by the lifting cylinder frame 104 to approach the top and bottom of the single-layer main frame and maintain a certain distance from them. A linear cylinder is provided inside the telescopic arm 602, which drives the rod section of the telescopic arm 602 to expand, prompting the anti-slip wheel 604 to move close to the inner wall of the single-layer main frame.

[0040] A rotating motor 603 is provided at one end of the telescopic arm 602 away from the adjusting arm 601, and an anti-slip wheel 604 is sleeved on the bottom of the rotating motor 603. The output end of the rotating motor 603 is connected to the anti-slip wheel 604 frame through accessories, and drives the anti-slip wheel 604 to deflect with the rotating motor 603 as the central axis until the anti-slip wheel 604 deflects and abuts against the inner wall of the single-layer main frame, which cooperates with the traction moving component 5 to realize multiple limiting between the assembly base 1 and the single-layer main frame.

[0041] When the traction moving component 5 drives the assembly base 1 to move, the anti-slip wheel 604 moves along the inner wall of the single group main frame, and the anti-slip wheel 604 frame, the telescopic arm 602 and the adjustment arm 601 form a movement limiting traction for the assembly base 1.

[0042] One end of the extension frame 501 is connected to the lifting cylinder frame 2 105, and a driving motor 502 is embedded in the frame body of the extension frame 501. The extension frame 501 is driven by the lifting cylinder frame 2 105 to move closer to each other until the driving wheel 503 abuts against the middle of the top and bottom surfaces of the single-layer main frame, forming a concave lock. The driving motor 502 drives the driving wheel 503 to rotate through the transmission shaft, thereby driving the assembly base 1 to move along the outer area of the single-layer main frame.

[0043] The output end of the driving motor 502 is provided with a transmission shaft that passes through the extension frame 501 and is sleeved with the driving wheel 503. A telescopic connecting rod 505 connected to the transmission shaft is provided inside the electromagnetic wheel ring 504. When positioning operation is required, the electromagnetic wheel ring 504 is composed of several arc frames spliced together to form a ring shape, and an electromagnet is embedded inside the arc frame. When the electromagnet is energized, it generates magnetic force and adsorbs on the single-layer main frame. The arc frame close to the single-layer main frame is pulled down by the magnetic force, and it drags the telescopic connecting rod 505 to unfold. When the assembly base 1 needs to move, the arc frames in the rotation direction of the electromagnetic wheel ring 504 contact the single-layer main frame one by one, and the arc frames moving in the opposite direction are separated from the single-layer main frame one by one by the rotation of the electromagnetic wheel ring 504.

[0044] Embodiment 2: This embodiment is a spot welding assembly calibration component for a pulping and cooking tower, including a welding adjustment component 3 including a limit column 301 and a lifting cylinder frame 304, a welding mounting frame 306 is provided on the top of the lifting cylinder frame 304, and a calibration component 4 includes a telescopic column 402, and a leveling measuring rod 403 and a mechanical arm rod 407 are respectively provided on both sides of the top of the telescopic column 402. When the assembly base 1 moves to the area where external welding is required, the transverse cylinder frame 101 drives the calibration component 4 to slide along the top of the assembly base 1.

[0045] The top of the limiting column 301 is provided with an extension sleeve rod 302 connected to the lifting cylinder frame 304, the bottom of the lifting cylinder frame 304 is provided with a rotary cylinder 303 connected to the extension sleeve rod 302, and the frame body of the lifting cylinder frame 304 is provided with a movable sleeve block 305 connected to the welding mounting frame 306.

[0046] A connecting block 401 connected to the transverse cylinder frame 101 is provided at the bottom of the telescopic column 402, and a rotary cylinder 2 404 is provided at the top of the telescopic column 402. An adjusting sleeve 1 405 connected to the leveling measuring rod 403 is provided on one side of the rotary cylinder 2 404, and an adjusting sleeve 2 406 connected to the mechanical arm rod 407 is provided on the other side of the rotary cylinder 2 404. In the initial state, the mechanical arm rod 407 is close to the outer wall of the tower body component, and the leveling measuring rod 403 is away from the outside of the tower body component. After the inspection of this group of tower body components is completed, the lifting cylinder frame 304 drives the welding machine to approach the connection area of the tower body component through the moving sleeve block 305 and the welding mounting frame 306, and the welding machine performs spot welding reinforcement on it.

[0047] A rectangular groove is provided on the outer wall of the adjusting sleeve 405, and a micro motor is embedded on the inner wall of the rectangular groove. The top of the leveling measuring rod 403 is embedded in the rectangular groove, and a middle rod connected to the micro motor is connected to the middle of the leveling measuring rod 403. Infrared scanning sensors and industrial cameras are embedded on the surface of the leveling measuring rod 403 and the middle rod.

[0048] The required welding area is inspected in advance, and the rotary cylinder 2 404 drives the mechanical arm rod 407 and the leveling rod 403 to rotate until the leveling rod 403 rotates close to the outside of the tower body component. According to the state of the initially installed tower body component, the rotary cylinder 3 drives the adjustment sleeve 1 405 to rotate, so that the leveling rod 403 and the group of tower body components remain flush in the axial direction. The micromotor drives the middle rod to slide upward along the middle part of the leveling rod 403 to expand, which is used to scan and photograph the current installation status of the group of tower body components for forming detection, and transmit it to the controller of the device operator so that the operator can perform spot welding according to actual conditions.

[0049] A rotary cylinder three is provided in the middle of the adjusting sleeve 1 405 and the adjusting sleeve 2 406, and a rotary cylinder four is provided on the outer side of the adjusting sleeve 2 406 for connecting to the top of the mechanical arm rod 407. A plurality of rod sections and pneumatic clamps are provided on the rod body of the mechanical arm rod 407. When there is an abnormality in the installation of the group of tower components, the leveling measuring rod 403 is reset, and the rotary cylinder 2 404 drives the leveling measuring rod 403 and the mechanical arm rod 407 to rotate until the mechanical arm rod 407 is close to the outside of the tower component. The rotary cylinder four drives the mechanical arm rod 407 to rotate and lift. At the same time, the plurality of rod sections on the mechanical arm rod 407 are started synchronously, and an adaptor cylinder is provided between the plurality of rod sections to drive the adjustment until the pneumatic clamp is moved close to the group of tower components and clamped and adjusted, or the installation position of the group of tower components is adjusted under the collaborative operation of the installation personnel inside the tower body.

[0050] After the spot welding installation of the tower body components on the outside of the cooking tower is completed, the assembly base 1 is moved around along the single-layer main frame, and the calibration component 4 and the mechanical arm 407 are used to inspect the external tower body components one by one to avoid inadequate spot welding installation or abnormal areas. During the subsequent use of the cooking tower, if there is an abnormal installation of some external tower body components, the abnormal area is repaired by the lifting device.

[0051] Combining the first and second embodiments, the flexible adjustment and stable movement design can not only achieve precise operation on the high-difficulty welding area on the outside, improve work efficiency and safety, but also ensure the accuracy of the welding position through the calibration component 4, thereby improving the welding quality.

[0052] In addition, the device also facilitates the subsequent regular inspection and maintenance of the tower components, timely discovering and repairing potential problems, ensuring the long-term stable operation of the cooking tower, and bringing significant optimization and improvement to the entire production process.
