Description

Technical Field

[0001] This utility model relates to the technical field of submerged arc welding machine facilities, specifically to a trolley-type submerged arc welding machine. Background Technology

[0002] In traditional submerged arc welding machine designs, the height adjustment of the welding head typically requires manual operation, which is not only inefficient but also difficult to control precisely. Furthermore, the high temperature of the welding head during welding often necessitates additional cooling systems, but these systems are often bulky, energy-intensive, and difficult to integrate into the welding equipment. Simultaneously, the delivery and control of welding materials present a significant technical challenge, requiring precise control to ensure weld quality. Moreover, the movement accuracy and stability of the welding equipment are also crucial for guaranteeing weld quality.

[0003] A search revealed a trolley-type submerged arc welding machine with announcement number CN205032834U, belonging to the field of welding equipment technology; the trolley-type submerged arc welding machine includes a conductive nozzle mounted on the welding machine body, the conductive nozzle facing downwards and inclined at an angle α with respect to the horizontal direction, 15°≤α≤30°;

[0004] The above-mentioned vehicle-mounted submerged arc welding machine replaces the traditional manual welding solution, but it cannot ensure that it can move in a straight line, nor can it adjust the height of the welding head, nor can it cool the welding head during the welding process.

[0005] Therefore, a new type of trolley-type submerged arc welding machine needs to be designed. Utility Model Content

[0006] This invention provides a trolley-type submerged arc welding machine that can achieve automated height adjustment, cooling of the welding head, precise material feeding control, and linear movement of the trolley.

[0007] A trolley-type submerged arc welding machine includes a trolley, characterized in that: a fixed end of a vertical moving component is fixed on the upper side of the trolley, the movable end of the vertical moving component is connected to a submerged arc welding machine bracket, the bracket is fixedly connected to the submerged arc welding machine body and the hopper, a distance sensor is provided on the lower outer wall of the welding head of the submerged arc welding machine body, a cold end of a semiconductor refrigeration chip assembly is fixed on the lower outer wall of the welding head, and a fan is provided on one side of the hot end of the semiconductor refrigeration chip assembly;

[0008] A temperature sensor is also provided on the hot end side of the semiconductor cooling chip assembly.

[0009] As a further limitation of this technical solution, the outlet of the hopper is connected to a feeding pipe, the upper end of the feeding pipe is equipped with a solenoid valve, and the outlet of the feeding pipe corresponds to the welding head.

[0010] As a further limitation of this technical solution, it also includes a support base, on one side of which is fixed a transmitting end of at least one through-beam sensor, and on the front side of the vehicle body of the trolley, corresponding to the position of the through-beam sensor, a receiving end of the through-beam sensor is provided.

[0011] As a further limitation of this technical solution, a controller is also provided. The controller is electrically connected to the vertical moving component, the fan, the semiconductor cooling chip assembly, and the solenoid valve. The controller communicates with the distance sensor, the temperature sensor, and the through-beam sensor through a transmission module. The distance sensor is used to detect the distance between the welding head and the welded object. The temperature sensor is used to monitor the temperature of the heat dissipation end of the semiconductor cooling chip. The through-beam sensor is used to ensure that the trolley travels in a straight line.

[0012] As a further limitation of this technical solution, the vertical moving component is an electric push rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are:

[0014] The height of the welding head is automatically adjusted by a vertical moving component;

[0015] By integrating semiconductor cooling chip components and fans, efficient cooling of the welding head is achieved, reducing thermal deformation and oxidation during the welding process and improving welding quality;

[0016] Temperature sensors monitor the temperature in real time and the controller automatically adjusts the working status of the fan to accelerate heat dissipation and further protect the welding joint;

[0017] The use of solenoid valves enables precise delivery and control of welding materials, improving the stability of the welding process and the utilization rate of materials.

[0018] The use of through-beam sensors ensures that the trolley moves in a straight line, improving the movement accuracy and stability of the welding equipment. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] A trolley-type submerged arc welding machine includes a trolley 8. A fixed end of a vertical moving component 9 is fixed to the upper side of the trolley 8. The movable end of the vertical moving component 9 is connected to a submerged arc welding machine bracket 1. The bracket 1 is fixedly connected to a submerged arc welding machine body 81 and a hopper 2. A distance sensor 7 is provided on the lower outer wall of the welding head 5 of the submerged arc welding machine body 81. The distance sensor is fixed to a mounting base 6. The mounting base 6 fixes the welding head 5. The cold end of a semiconductor refrigeration chip assembly 11 is fixed to the lower outer wall of the welding head 5. A fan 10 is provided on one side of the hot end of the semiconductor refrigeration chip assembly 11.

[0027] A temperature sensor is also provided on the hot end side of the semiconductor cooling chip assembly 11.

[0028] In this embodiment, the movable end of the vertical moving component 9 lifts and lowers, driving the submerged arc welding machine body 81 and hopper 2 to lift and lower, adjusting the height of the welding head 5 to a suitable position, thereby achieving height adjustment of the welding head 5.

[0029] The semiconductor cooling chip assembly 11 includes a semiconductor cooling chip housing and a semiconductor cooling chip. The cooling end of the semiconductor cooling chip contacts the welding head 5 to cool the welding head 5. A fan 10 is provided at the heat dissipation end. A temperature sensor monitors the temperature. When the temperature is too high, the fan 10 works to accelerate heat dissipation.

[0030] The outlet of the hopper 2 is connected to the feed pipe 22, and a solenoid valve 21 is installed at the upper end of the feed pipe 22. The outlet of the feed pipe 22 corresponds to the welding head 5.

[0031] The solenoid valve 21 can control the feeding of material through the feeding pipe 22, and is easy to use.

[0032] It also includes a support base 3, which is installed on the operating table or the ground (the prior art will not be described in detail). At least one transmitting end of the through-beam sensor 4 is fixed on one side of the support base 3, and the receiving end of the through-beam sensor 4 is provided on the front side of the vehicle body of the trolley 8 corresponding to the position of the through-beam sensor 4.

[0033] Furthermore, the vehicle 8 is a mobile vehicle that is driven by a servo motor, and the through-beam sensor 4 ensures that the vehicle moves in a straight line.

[0034] A controller is also provided, which is electrically connected to the vertical moving component 9, the fan 10, the semiconductor cooling chip assembly 11, and the solenoid valve 21. The controller communicates with the distance sensor 7, the temperature sensor, and the through-beam sensor 4 through a transmission module. The distance sensor 7 is used to detect the distance between the welding head 5 and the welded object. The temperature sensor is used to monitor the temperature of the heat dissipation end of the semiconductor cooling chip. The through-beam sensor 4 is used to ensure that the trolley 8 travels in a straight line.

[0035] The vertical moving component 9 is an electric push rod.

[0036] During operation, the trolley 8 moves, and the through-beam sensor 4 ensures that the trolley can move in a straight line. When the trolley 8 moves to the object to be welded, the electric push rod controls the welding head 5 to move down to a suitable height. The distance sensor 7 monitors the distance between the welding head 5 and the object to be welded in real time. When the distance is suitable, the controller controls the electric push rod to stop working, and the submerged arc welding machine starts working to perform welding. During this process, the controller controls the opening and closing of the solenoid valve 21 to realize the feeding and stopping of feeding. The temperature sensor monitors the temperature and feeds it back to the controller. When the temperature is too high, the controller controls the fan 10 to work to accelerate heat dissipation.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
