Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of equipment tooling, particularly to a riser cutting torch. BACKGROUND

[0002] Riser cutting work has always been intensive, and the operators need to perform manual operation in a high-temperature, high-noise, and harsh environment. In addition, they also face multiple safety risks such as molten steel splashing and heavy object injury, which not only threaten their life safety, but also bring double pressure of recruitment difficulty and high labor protection cost to enterprises. However, with the continuous expansion of the application field of robots, the field of flame cutting riser has also begun to welcome the application of robots. This not only effectively reduces the work intensity and safety risk of manual work, but also greatly relieves the recruitment pressure of enterprises.

[0003] However, when the robot uses the flame cutting method to cut the riser, it also faces some challenges. Since some risers are located in the middle of the casting, when the robot clamps the torch for cutting, due to the limited length of the torch, the robot body may interfere with the casting body when the torch is close to the cutting position. In this case, the torch cannot approach the riser cutting position due to insufficient length, resulting in the failure to complete the cutting task. In addition, for some cases where there are casting body parts around the riser, if the torch is too long, it may interfere with the casting body during cutting, and thus cannot be cut smoothly. Therefore, the fixed length of the torch becomes a limiting factor, and both too long and too short cannot adapt to more cutting positions, which brings inconvenience to the operation. SUMMARY

[0004] Therefore, it is necessary to provide a riser cutting torch to solve the problem that the fixed length of the riser cutting torch is difficult to adapt to the riser cutting work.

[0005] To solve the above problems, the utility model adopts the following technical solutions:

[0007] In one embodiment, both ends of the connecting mechanism are rotationally connected with the torch body and the torch head through rotating parts, and the rotating parts drive the torch body and the torch head to rotate.

[0008] In one embodiment, a locking portion is arranged on the rotating portion, and the locking portion is used to lock the rotating portion at a preset position.

[0009] In one embodiment, a splicing portion is arranged, and one end of the splicing portion is detachably connected to the end of the torch head.

[0010] In one embodiment, a cutting nozzle is arranged, and the cutting nozzle is detachably connected to the other end of the splicing portion and the end of the torch head.

[0011] In one embodiment, the torch body is a telescopic structure.

[0022] In order to facilitate understanding of the utility model, the utility model will be described more fully below with reference to the relevant drawings. The preferred embodiments of the utility model are shown in the drawings. However, the utility model can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as "provided on" another element, it can be directly on the other element or there can be a middle element.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing the specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] As Figures 1-2 shown, the utility model embodiment discloses a riser cutting torch, the disclosed riser cutting torch includes cutting torch main body 100, connecting mechanism 200 and cutting torch head 300.

[0026] The cutting torch body 100 is the main structure of the entire cutting torch, responsible for providing power sources (such as gas or electricity) and control devices to drive the cutting operation of the cutting torch head. The cutting torch body 100 should be designed to be sturdy, durable, easy to hold and operate. One end of the connecting mechanism 200 is rotatably connected to the end of the cutting torch body 100, and the other end of the connecting mechanism 200 is rotatably connected to the cutting torch head 300. The connecting mechanism 200 drives the cutting torch head 300 to move to change the distance between the end of the cutting torch head 300 and the end of the cutting torch body 100. This double rotary connection design allows the connecting mechanism 200 to drive the cutting torch head 300 to move freely in three-dimensional space, thereby changing the distance and direction between the end of the cutting torch head 300 and the end of the cutting torch body 100. The connecting mechanism 200 can adopt a ball hinge, universal joint or other structural form to achieve flexible and stable connection.

[0027] The cutting torch head 300 is the key component for performing cutting operations, which can typically include a cutting nozzle, an electrode (for electric spark cutting) or a flame port (for gas cutting) and other structures. The design of the cutting torch head 300 should be able to adapt to different cutting media and cutting conditions to ensure cutting efficiency and cutting quality.

[0028] In use, compared with Figure 1 and Figure 2 , the operator can flexibly change the position and attitude of the cutting torch head 300 by adjusting the rotation angle of the connecting mechanism 200 to adapt to different shapes and sizes of risers. This adjustment can be achieved by manual operation or electric / pneumatic control, depending on the design of the cutting torch body 100. Once the cutting torch head 300 is adjusted to the appropriate position, the operator can start the cutting torch body 100 for cutting operation.

[0029] From the above, it can be seen that in the riser cutting torch disclosed in the embodiments of the present application, the connecting mechanism 200 drives the cutting torch head 300 to move, which can change the distance between the end of the cutting torch head 300 and the end of the cutting torch body 100, thereby realizing accurate cutting of risers with different depths and angles. This adjustability ensures the flatness and smoothness of the cutting surface, reduces the workload of subsequent processing, and improves the overall cutting efficiency and quality. At the same time, the present application designs the connecting mechanism 200 innovatively, so that the operator can operate at a safer distance and angle, effectively reducing the risk in the operation process and improving the job safety. Furthermore, the structure is simple and clear, easy to check and maintain daily, prolonging the service life of the cutting torch.

[0030] Further, both ends of the connecting mechanism 200 can be rotatably connected with the torch body 100 and the torch head 300 through the rotating part 400, and the rotating part 400 can drive the torch body 100 and the torch head 300 to rotate. At this time, the introduction of the rotating part 400 can automatically drive the torch body 100 and the torch head 300 to rotate, effectively avoiding the inconvenience of directly rotating by manpower in the traditional way, greatly reducing the labor intensity of the operator. Secondly, this design significantly improves the automation level of operation, making the entire cutting process more smooth and efficient, which helps to improve production efficiency and product quality. In addition, the realization of automatic rotation also helps to reduce errors that may be caused by improper human operation, further improving the precision and safety of cutting operations

[0031] The riser cutting torch disclosed in the embodiment of the utility model can also include a locking part, which can be arranged on the rotating part 400, and the locking part can be used to lock the rotating part 400 at a preset position, so that when it is necessary to fix the angle or position, the torch body 100 and the torch head 300 can be stable and immovable, avoiding the angle deviation caused by misoperation or external force interference. This function not only improves the precision and safety of cutting operations, but also further enhances the stability and reliability of the equipment.

[0032] The riser cutting torch disclosed in the embodiment of the utility model can also include a splicing part 600, one end of the splicing part 600 can be detachably connected with the end of the torch head 300. In this case, one end of the splicing part 600 can be detachably connected with the end of the torch head 300, and this design makes the overall length of the torch adjustable according to actual needs. Especially when facing different positions and heights of riser cutting operations, the operator does not need to replace the entire torch, but only needs to increase or decrease the number of splicing parts 600 to easily adapt, greatly improving the flexibility and convenience of cutting operations. Since the splicing part 600 can easily increase the length of the torch, the operator can complete the riser cutting of the area that is difficult to reach without frequent movement or adjustment of the posture, thereby effectively reducing the operation time and physical exertion and improving the overall operation efficiency.

[0033] The riser cutting torch disclosed in the embodiment of the utility model can also include a cutting nozzle 500, which is detachably connected with the other end of the splicing part 600 and the end of the torch head 300. At this time, this connection method not only makes the replacement and maintenance of the cutting nozzle 500 more convenient, but also improves the overall flexibility and adaptability of the torch. In actual operation, the user can replace the appropriate cutting nozzle according to the specific cutting requirements, so as to maximize the cutting effect and efficiency.

[0034] In addition, the detachability of the cutting nozzle further facilitates the detachable connection between the cutting gun head 300 and the splicing part 600. This design allows the user to easily detach the cutting nozzle from the cutting gun head 300 when needed, and then add the splicing part 600 to facilitate the overall flexibility and adaptability of the cutting gun.

[0035] Further, the cutting gun body 100 can be a telescopic structure, which enhances the flexibility and adaptability of the cutting gun, allowing it to adapt to different working environments and space limitations, improving work efficiency. The operator can easily adjust the length of the cutting gun body 100 according to actual needs to achieve the best working position and angle, thereby ensuring the accuracy and safety of the work.

[0036] The riser cutting cutting gun disclosed in the embodiments of the utility model can further include a position sensor, which is arranged on the cutting gun head 300. The position sensor can be used to detect the distance between the cutting gun head 300 and the welding position. This way can effectively avoid cutting errors caused by improper distance judgment, thereby improving the work quality and safety.

[0037] The riser cutting cutting gun disclosed in the embodiments of the utility model can further include a control mechanism, which is communicatively connected with the position sensor and the rotating part 400. The control mechanism can control the rotating part 400 through the position detection of the position sensor. At this time, the control mechanism can quickly and accurately adjust the working state of the rotating part 400, such as speed and direction, according to the distance information fed back by the position sensor in real time. This intelligent control method not only improves the work efficiency, but also ensures the stability and continuity during cutting, further improving the automation level of the overall operation.

[0038] Further, the connecting mechanism 200 includes at least two joint parts, and the adjacent two joint parts are rotationally connected. This design not only enhances the flexibility and adaptability of the connecting mechanism 200, allowing it to maintain stable connection performance in various complex environments, but also significantly improves the movement range and operability of the entire device. Specifically, the rotational connection of the joint part allows the connecting mechanism 200 to be freely adjusted at different angles and directions, thereby meeting the needs of various actual application scenarios. This flexibility allows the device to better adapt to different working environments, improving work efficiency and accuracy.
