Description

Technical Field

[0001] This application relates to the field of long-tube transfer equipment technology, and in particular to an ultra-long spray gun transfer device. Background Technology

[0002] In industrial environments such as metal smelting, the spray gun is a key piece of equipment for injecting pulverized coal, pulverizing auxiliary materials, and regulating the atmosphere inside the furnace. Spray guns are typically connected to large pipelines, are quite long (up to tens of meters), and are heavy. To ensure the continuity and safety of the smelting process, the spray guns need to be disassembled and inspected regularly, requiring the use of specialized transport equipment.

[0003] Currently, the transfer process after the spray gun is disassembled mainly relies on the cooperation of metallurgical bridge cranes and forklifts. First, the bridge crane used by the operator lifts the disassembled spray gun from the maintenance position, while the forklift provides auxiliary support from the other end of the spray gun to prevent it from sagging or swinging due to its excessive length. Then, the bridge crane and forklift transport the spray gun to the maintenance area or storage area in a synchronized and slow horizontal movement. If turning or adjusting direction is required during the transfer, the bridge crane and forklift must perform complex steering operations separately, requiring a high degree of coordination from the drivers; otherwise, the spray gun may twist, collide with surrounding equipment, or slip. After reaching the designated position, the bridge crane and forklift in the maintenance workshop are also used to adjust the spray gun to a suitable placement posture. Throughout the process, the spray gun is repeatedly lifted, aligned, and its angle is adjusted multiple times.

[0004] In the existing process of transporting spray guns, the spray guns are long, difficult to turn, and have extremely low transport efficiency, which seriously affects the overall progress of spray gun maintenance. They rely on the precise coordination of equipment such as bridge cranes and forklifts, which is difficult to operate. The slightest carelessness may damage the spray gun or cause a safety accident. In addition, the equipment occupies a lot of space and is not suitable for complex smelting sites. During the transport process, the spray guns lack a dedicated clamping and fixing structure and are only lifted by slings or forklifts, which makes the spray guns easy to shake and slip. Therefore, there is an urgent need to provide a device that can achieve efficient, stable, and flexible transfer of spray guns to solve the problems of low efficiency in spray gun maintenance and transfer, complex operation, and poor clamping stability. Summary of the Invention

[0005] To address or partially address the problems existing in related technologies, this application provides an ultra-long spray gun transfer device, which aims to solve the problems of low efficiency in spray gun maintenance and transfer, complex operation, and poor clamping stability.

The slide rails are detachably installed on the hinge seats. The other end of the slide rail is connected by a connecting rod. A screw nut is installed on the connecting rod, and a screw is installed on the screw nut. The front end of the screw is connected to the upper clamping groove through a fixed bearing. The upper clamping groove has a semi-circular groove with the same diameter as the spray gun. By rotating the screw, the upper clamping groove can move up and down between the slide rails.

[0008] Optionally, the first spray gun clamping mechanism and the second spray gun clamping mechanism have the same structure; wherein, the gun barrel support beam of the second spray gun clamping mechanism is installed on both sides of the gun barrel support seat.

[0009] Optionally, sliders are installed on both sides of the upper clamping groove. The sliders can slide on the slide rail, allowing the upper clamping groove to move along the slide rail.

The nozzle head transfer device uses the first spray gun clamping mechanism and the lower clamping groove to stably clamp the nozzle head from both ends, while the nozzle shaft transfer device uses the second spray gun clamping mechanism and the lower clamping groove of the nozzle shaft to stably clamp it, avoiding the risk of spray gun shaking or slippage during transfer. In the nozzle head transfer device, the nozzle head support is rotatably mounted on the chassis via a bottom pivot, allowing the nozzle head to rotate freely in the horizontal plane.

[0027] The base frame 8 is installed at the other end of the clamping arm 4; the first lower clamping groove 5 is fixedly installed on the clamping arm 4 between the first spray gun clamping mechanism 6 and the base frame 8; a second lower clamping groove 17 is also fixedly installed on the clamping arm 4 between the first spray gun clamping mechanism 6 and the base frame 8. Both the first lower clamping groove 5 and the second lower clamping groove 17 have semi-circular grooves with the same diameter as the spray gun.

[0028] The first spray gun clamping mechanism 6 cooperates with the first lower clamping groove 5 and the second lower clamping groove 17 to clamp and fix the spray gun head from both the upper and lower ends.

[0029] The gun barrel transfer device includes a second spray gun clamping mechanism 10, a gun barrel support beam 11, a gun barrel support seat 12, a lower gun barrel clamping groove 13, a moving flatcar 14, and casters 15. The moving flatcar 14 has casters 15 mounted at its four corners, with at least two of the casters 15 equipped with brakes.

The clamping principle and action mode are the same. The hinge hole on the slide rail of the second spray gun clamping mechanism 10 is an oblong hole, and the gap of the hinge seat is relatively large. After the slide rail pin is hinged or bolted to the hinge seat, the second spray gun clamping mechanism 10 can be deflected at a certain angle in the vertical direction.

[0030] The second spray gun clamping mechanism 10 and the lower clamping groove 13 clamp and fix the spray gun barrel from the upper and lower ends.

[0031] See Figure 4 This application describes a spray gun transfer device for transferring disassembled extra-long spray guns from the disassembly location to the maintenance area or from the maintenance area to the installation location. The steps for transferring the long spray gun from the disassembly location to the maintenance area are as follows: After the top-blowing spray gun is removed from the metallurgical furnace, it is lifted and lowered by a bridge crane 1. When the spray gun head is close to the transfer ground, the gun head transfer device is installed on a forklift and moved to below the spray gun head, so that the first lower clamping groove 5 and the second lower clamping groove 17 are aligned with the predetermined support point of the spray gun head. The spray gun is slowly lowered so that the spray gun head falls into the semi-circular groove of the first lower clamping groove 5 and the second lower clamping groove 17. The disassembled slide rail 603, upper clamping groove 605, lead screw nut 607, screw 608, etc. are reinstalled on the hinge seat 602 to clamp the gun head. The screw 608 is rotated so that the screw 608 moves under the action of the lead screw nut 607, pushing the upper clamping groove 605 down through the fixed bearing 606 until the semi-circular groove of the upper clamping groove 605 presses against the surface of the spray gun head. Because the lead screw and nut pair has a self-locking characteristic, the clamping force remains constant after rotation stops, and the gun head is firmly clamped between the first spray gun clamping mechanism 6 and the first lower clamping groove 5 and the second lower clamping groove 17.

[0032] The forklift is controlled to move the nozzle transfer device, simultaneously lowering the spray gun and rotating the clamping arm 4 to adjust the spray gun's tilt angle, thus changing the spray gun from vertical to horizontal movement. When the spray gun is almost horizontal, the gun barrel transfer device is moved to the area below the gun barrel near the connecting end, aligning the lower clamping groove 13 with the spray gun barrel, allowing the spray gun barrel to fall into the lower clamping groove 13. Then, the second spray gun clamping mechanism 10 is installed, and the screw on the second spray gun clamping mechanism 10 is rotated to lower its upper clamping groove, pressing the upper surface of the spray gun barrel to complete the clamping and fixing of the gun barrel. The rigging of the bridge crane 1 is then released, and the spray gun is transferred horizontally.

[0033] During horizontal transfer, the operator uses a forklift to move the gun transfer device, adjusting its configuration according to the terrain and road conditions. On straight sections: The forklift travels forward at a constant speed, with the boom transfer device following synchronously, maintaining a constant relative distance between them. Avoid ground obstacles along the way, and adjust the forklift fork height slightly if necessary.

[0034] When turning, the nozzle head turns first. The forklift driver controls the forklift to turn, and the nozzle head support 2 in the nozzle head transfer device rotates horizontally on the chassis 1 via the bottom pivot 9. The angle of the clamping arm 4 remains unchanged, and the forklift drives the spray gun head to smoothly change direction. The moving flatcar 14 of the gun barrel transfer device is equipped with casters 15. The operator pushes it synchronously along the curve. At the same time, the gun barrel support 12 rotates freely on the moving flatcar 14 via bearings, so that the gun barrel support 12 can automatically follow the swing direction of the spray gun and avoid generating torque.

[0035] On sloping or undulating roads, the clamping arm 4 of the nozzle transfer device can be tilted up and down via the clamping arm pivot 16, and the second spray gun clamping mechanism 10 of the gun barrel transfer device will also adjust its tilt simultaneously to automatically adapt to changes in road slope and maintain the spray gun in a horizontal position relative to the ground.

[0036] After the spray gun is transferred to the designated location in the maintenance area or storage area, the first spray gun clamping mechanism 6 and the second spray gun clamping mechanism 10 are disassembled respectively, and the spray gun is unloaded and placed on the ground using a lifting device.

[0037] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
