Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a new energy flash welding machine. Background Technology

[0002] A flash welding machine (also known as a flash butt welding machine) is a welding device that uses resistance heat and the flash effect to join metal workpieces together. It is a type of resistance welding machine. It melts the metal at the contact point of the workpiece by generating high temperature with current, and then applies upsetting force to complete the welding. It is widely used in industrial manufacturing.

[0003] For existing flash welding machines used in rail welding, especially in tunnel construction, they mainly rely on generator drive or direct power supply from the urban power grid. The three-phase voltage output by the generator is prone to imbalance, which leads to fluctuations in welding current, affects the stability of flash welding, and causes defects such as incomplete fusion and gray spots to appear at the joint. In addition, the voltage fluctuation range generated by the generator is large, making it difficult to match the transient power requirements of the welding machine. Meanwhile, the generator consumes oxygen and emits CO, NOx and particulate matter during operation, which exacerbates air pollution in enclosed spaces such as tunnels and underground projects, threatening construction safety. Therefore, traditional flash welding machines urgently need to be improved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a new energy flash welding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A new energy flash welding machine includes a cabin, one end of which is equipped with a welding boom. The welding boom is driven by a hydraulic power unit, and the front end of the welding boom is equipped with a welding head that is driven to rise and fall by a sprocket transmission mechanism. The welding head is powered by a new energy mechanism. The new energy mechanism is located inside the cabin. The new energy mechanism includes a charging generator, an inverter, a water cooling mechanism, a fire protection mechanism, and multiple sets of batteries. Each set of batteries is equipped with a heat exchange pipe on its outside, and the heat exchange pipe is circulatedly connected to the water cooling mechanism.

[0006] In addition, a preferred configuration is that the cabin is equipped with a main control cabinet, and a display is installed on top of the main control cabinet. The signal input terminal of the display is connected to the data output port of the main control cabinet via a wire to achieve visual operation.

[0007] Furthermore, in a preferred configuration, the printer is located on the side furthest from the main control cabinet.

[0008] Furthermore, in a preferred configuration, the support for the welding boom is an electrically rotating support, and its rotation is controlled by a new energy mechanism.

[0009] In addition, a preferred configuration is that a hydraulic power unit is installed on one side of the interior of the cabin, which drives the welding boom.

[0010] Furthermore, a preferred structure is that a water-cooling mechanism is provided on the side away from the new energy mechanism.

[0011] The beneficial effects of this utility model are as follows: In this invention, a new energy mechanism is installed inside the engine compartment to replace the traditional gasoline generator. The new energy mechanism provides stable and efficient power output, avoiding the three-phase imbalance problem of the traditional device. A water-cooling mechanism is also used to ensure the temperature stability of the battery pack, thereby improving its operational stability. At the same time, the generation of corresponding harmful gases is eliminated, ensuring more stable welding quality while meeting environmental requirements. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-3 The new energy flash welding machine includes a cabin 1, one end of which is equipped with a welding boom 2, which is driven by a hydraulic power unit 7. The welding boom 2 is equipped with a welding head 4 that is driven to lift by a sprocket transmission mechanism. The welding head 4 is powered by a new energy mechanism 6. The power input end of the sprocket drive mechanism is connected to the drive motor. The drive motor controls the main drive sprocket to rotate so as to drive the toothed chain to move up and down. The toothed chain connection end is connected to the welding head 4 to achieve synchronous movement.

[0016] The new energy mechanism 6 is located inside the engine compartment 1. The new energy mechanism 6 includes a charging generator 61, an inverter, a water cooling mechanism 5, a fire protection mechanism, and multiple sets of batteries. Each set of batteries is equipped with a heat exchange pipe on its outer side, and the heat exchange pipe is circulatedly connected to the water cooling mechanism 5.

[0017] The fire protection system includes multiple fire extinguishers located next to the battery pack.

[0018] The cabin 1 is equipped with a main control cabinet 32. A display 3 is installed on the top of the main control cabinet 32. The signal input terminal of the display 3 is connected to the data output port of the main control cabinet 32 ​​via a wire to realize visual operation.

[0019] A printer 31 is located on the side away from the main control cabinet 32.

[0020] The support for the welding boom 2 is an electric rotating support, and its rotation is controlled by the new energy mechanism 6.

[0021] A hydraulic power unit 7 is installed on one side of the interior of the cabin 1, which drives the welding boom 2.

[0022] A water-cooling mechanism 5 is located on the side away from the new energy mechanism 6.

[0023] In this embodiment, a new energy mechanism 6, which includes a charging generator 61, an inverter, a water cooling mechanism 5, a fire-fighting mechanism, and multiple sets of batteries, replaces the gasoline generator of the traditional device. The entire power system has a stable power output and can directly output two phases for welding needs, avoiding the three-phase imbalance problem of the generator output and improving the life of the equipment. Meanwhile, the welding process using the new energy mechanism 6 has small voltage fluctuations, stable welding process, and low noise, eliminating the unstable factors of traditional generator drive voltage and many shortcomings of generators. Especially in tunnel construction, it can alleviate smoke and dust pollution and internal oxygen consumption, bringing more stable welding quality while meeting environmental requirements.

[0024] The welding boom 2 is driven by the new energy mechanism 6 to rotate, and the welding boom 2 is driven by the hydraulic power unit to perform actions such as extension, rotation, and lateral movement to realize the welding operation of the welding head 4.

[0025] For the multiple sets of batteries set in the new energy mechanism 6, the water cooling mechanism 5 circulates and pumps coolant to the heat exchange tubes to cool the batteries. Specifically, when the water temperature is ≥30℃, the pump in the water cooling mechanism 5 starts to perform self-circulation cooling; When the water temperature is ≥35℃, the water cooling components operate to cool the coolant. The equipment is in a dormant state when the water temperature is below 30℃.

[0026] Correspondingly, the water-cooling mechanism 5 is equipped with a temperature sensing module.
