The utility model provides self-propelled metal milling equipment, belongs to the technical field of metal processing, and aims to solve the problem that in the conventional metal milling equipment, rolling wheels are additionally mounted for facilitating movement, but the rolling wheels are unstably supported. And when the equipment runs, milling vibration can cause the problem that the equipment deviates due to non-uniform stress of the roller. Comprising a movable support, an equipment supporting body, a disintegrating slag collecting box, a vertical driving mechanism, a horizontal driving mechanism, a milling assembly, a supporting assembly and a transmission assembly, and the equipment supporting body is fixedly installed on the upper portion of the movable support; the disintegrating slag collecting box is clamped in the movable support; the vertical driving mechanism is arranged on the front side of the equipment supporting main body; the horizontal driving mechanism is mounted at the upper part of the vertical driving mechanism; the milling assembly is mounted at the upper part of the equipment supporting main body; the supporting assembly is arranged in the movable support. The transmission assembly is arranged in the horizontal driving mechanism. The device has the advantages of being stable in supporting, capable of treating scraps, convenient to use and the like.

This utility model belongs to the technical field of ventilated protective helmets or ventilated welding masks, and discloses an air supply mechanism, including a headband and an air duct. The air duct includes an outer connector, a fixed section, and a movable section connected in sequence. The air duct extends from the wearer's occipital region, around the wearer's top of the head, and toward the wearer's forehead. The headband has multiple mounting positions on the wearer's forehead. The movable section is detachably connected to one of the mounting positions. The air supply mechanism provided by this utility model features a fixed section of the air duct secured by a connecting strap, maintaining the stability of the air supply. The movable section is matched with multiple mounting positions, allowing for flexible adjustment of the air vent connection position and orientation. The air duct extends from the wearer's top of the head, avoiding interference between the air duct and other components.

This utility model discloses a large-angle directional column adjustment structure, including a fixed slot frame, a support inside the fixed slot frame, the support being movably connected to the fixed slot frame, the fixed slot frame including a rotating shaft passing through the bottom of the support and being rotatably connected to the support, a fixed cylinder inside the support, and an adjustment mechanism on one side of the fixed slot frame, one end of the adjustment mechanism being rotatably connected to the fixed cylinder, and the other end of the adjustment mechanism being rotatably connected to the fixed slot frame; through the large-angle adjustment structure, the disadvantages of limited transportation methods can be effectively improved during use, allowing the adjustment angle of the steering column to be increased and improving space utilization.

This utility model discloses a counterweight frame with inclined counterweight wheels, which consists of two identical symmetrical vertical beams. A bottom beam is fixedly connected to the bottom of the vertical beams, and an upper beam is fixedly connected to the top of the vertical beams. A middle vertical beam is also provided between the two vertical beams, and a counterweight block is provided between the two vertical beams and the middle vertical beam. The upper beam is composed of two parallel steel plates, and a counterweight wheel assembly is fixedly installed on the upper beam at an incline. The counterweight wheels of this utility model are mounted on the vertical plates and connected to the upper beam through the vertical plates, so that the adjustable angle of the counterweight wheels is greater, which is suitable for various construction scenarios.

This utility model relates to the field of self-aligning idler technology, specifically to a chain-type passive hydraulic self-aligning idler, including a fixed frame, an idler frame mounted on the fixed frame, and idlers mounted on the idler frame. It also includes a self-aligning mechanism mounted on the fixed frame. The idler frame includes a central support, a left support, and a right support respectively mounted at the middle and sides of the upper end of the fixed frame. The idlers are rotatably mounted on the central support, left support, and right support respectively. The self-aligning mechanism includes a drive cylinder mounted at the front of the fixed frame, a central shaft, a left shaft, and a right shaft rotatably mounted at the upper end of the fixed frame, a central swing arm plate, a left swing arm plate, and a right swing arm plate respectively fixed to the central shaft, left shaft, and right shaft, and a front chain and a rear chain respectively hinged to the front and rear ends of the central swing arm plate, left swing arm plate, and right swing arm plate. This utility model effectively improves the self-aligning idler's self-aligning effect by driving the three sets of idlers to rotate separately via the front and rear chains.

The utility model, which relates to the technical field of the box-type transformer station, discloses a rapid heat-dissipation preassembled box-type transformer station comprising a steel structure frame, two ends of which are respectively and fixedly connected with a high-voltage electric chamber isolation plate and a low-voltage electric chamber isolation plate. Symmetrical transformer chamber doors are arranged between the high-voltage electric chamber isolation plate and the low-voltage electric chamber isolation plate; air inlet filter screens are symmetrically embedded in each transformer chamber door, and one side, close to the steel structure frame, of each air inlet filter screen is movably connected with a rapid radiator through an airflow angle adjusting frame arranged in a rectangular array mode; according to the utility model, according to the different positions of the output rods of the electric cylinders and the different orientations of the cooling fans in the corresponding hollow frames, the orientations of the cooling fans are changed, so that airflow can be directly blown to the local heating position of the transformer through the cooling fans after entering, and the local serious heating position can be quickly cooled.
