Description

Technical Field

[0001] This utility model relates to the field of transfer device technology, and more specifically, to an Isa furnace spray gun transfer vehicle. Background Technology

[0002] As a crucial smelting equipment, the Isa furnace's lance is one of its core working components, primarily used to supply fuel or oxygen-enriched air to maintain the high-temperature reaction environment. The lance typically employs a long, straight cylindrical structure, exceeding 10 meters in length. Operating under harsh conditions of high temperature and high dust, the lance's surface is prone to slag buildup and coking, and its internal channels are easily clogged by impurities, requiring regular disassembly for cleaning, maintenance, or replacement. However, due to its large size and weight, coupled with limited space around the furnace, the horizontal transport and vertical handling of the lance present challenges in terms of operational difficulty and stability. Frequent handling operations place stringent demands on the coordination and safety of the transport tools.

[0003] Currently, the transfer of Isa furnace spray guns relies heavily on overhead cranes combined with manual assistance. This method requires multiple operators and suffers from problems such as difficulty in precisely controlling the hoisting trajectory and large swing amplitude of the spray gun, which can easily lead to collisions and damage to surrounding equipment. Furthermore, in the traditional handling process, only temporary pads are placed under the spray gun, which can easily slip and tip over when lowering or raising it, posing serious safety hazards. Moreover, the transfer efficiency is low, failing to meet the demands of efficient and continuous production in smelting workshops. Utility Model Content

[0004] The purpose of this invention is to provide an Isa furnace spray gun transfer vehicle, which solves the problem of the difficulty in accurately controlling the existing spray gun hoisting trajectory.

[0005] This utility model is achieved through the following technical solution: an Isa furnace spray gun transfer vehicle, including a flat car slidably mounted on a slide rail, a stop block at one end of the flat car, a positioning groove that mates with the lower part of the spray gun in a vertical state on the end face of the stop block facing the other end of the flat car, a guide groove plate for guiding the spray gun to be oriented, leveled and erected is provided between the flat car and the stop block, a sling is connected to the top of the spray gun, and when the sling is raised or lowered, the flat car moves synchronously in a straight line along the slide rail.

[0006] Furthermore, the flatcar is provided with a guide groove, which includes an irregular groove and a bottom groove. The irregular groove gradually converges towards the bottom groove, and the inner wall of the bottom groove is vertically flush with the inner wall of the positioning groove.

[0007] Furthermore, the flatcar is equipped with a locking block that engages with the upper part of the spray gun when it is laid flat.

[0008] Furthermore, the block includes a base and V-shaped legs.

[0009] Furthermore, the card block slides linearly along the length of the flatcar and is connected to the flatcar.

[0010] Furthermore, a cushioning pad is provided at the bottom of the card block.

[0011] Furthermore, the flatcar is provided with several buffer pads at intervals along its length that come into contact with the spray gun.

[0012] Furthermore, the buffer pad is made of polyurethane material, and the surface of the buffer pad has a concave arc surface that fits into the outer wall of the spray gun, and anti-slip texture is provided on the concave arc surface.

[0013] This utility model has at least the following advantages and beneficial effects: by synchronizing the movement of the flatcar and the sling, it ensures that the spray gun always moves along the predetermined trajectory during the erection / laying process, reducing operational risks; by cooperating with the positioning groove of the stop block and the guide groove plate, a double positioning of the lower end of the spray gun is formed; and by the groove constraint, precise guidance is achieved, preventing the spray gun from slipping during movement.

[0021] The specific implementation method is described below with reference to the accompanying drawings.

[0022] Example

[0023] like Figures 1 to 6As shown, this embodiment mainly discloses an Isa furnace spray gun transfer vehicle, including a flatcar 2 slidably mounted on a slide rail 1. A stop block 3 is provided at one end of the flatcar 2, and a positioning groove 30 is formed on the end face of the stop block 3 facing the other end of the flatcar 2 to cooperate with the lower part of the spray gun in a vertical state. A guide trough plate 4 is provided between the flatcar 2 and the stop block 3 to guide the spray gun to be oriented, leveled, and erected. A sling is connected to the top of the spray gun, and when the sling is raised or lowered, the flatcar 2 moves synchronously and linearly along the slide rail 1. Specifically, the flatcar 2 can cooperate with the I-beam slide rail 1 via a bottom roller assembly, and limit baffles are provided at both ends of the slide rail 1 to prevent derailment; the movement of the flatcar 2 can be started by a motor or a traction mechanism. The guide trough plate 4 consists of two triangular plates that gradually narrow towards the spray gun tilting direction, further guiding the spray gun to be leveled along the correct trajectory. The flatcar 2 and the sling move synchronously: when the sling is raised to erect the horizontally placed spray gun, the flatcar 2 moves towards the position near the projection of the lifting point; when the sling is lowered to lay the vertically placed spray gun horizontally, the flatcar 2 moves away from the projection of the lifting point. This ensures that the spray gun always moves along a predetermined trajectory during the erection / laying process, reducing operational risks. Simultaneously, the positioning groove 30 of the stop block 3 cooperates with the guide plate 4 to form a double positioning of the lower end of the spray gun. Precise guidance is achieved through groove constraints, preventing the spray gun from slipping during movement. It should be noted that the length of the flatcar 2 must be greater than the length of the spray gun to ensure that both ends of the spray gun are supported when laid horizontally, preventing bending deformation caused by suspension. The projection position of the sling lifting point should coincide with the linear movement trajectory of the flatcar 2.

[0024] Furthermore, in a specific implementation, the flatbed 2 provided in this embodiment of the present invention has a guide groove 20, which includes a shaped groove 201 and a bottom groove 202. The shaped groove 201 gradually converges towards the bottom groove 202, and the inner wall of the bottom groove 202 is vertically flush with the inner wall of the positioning groove 30. Specifically, the shaped groove 201 is funnel-shaped, which can automatically correct the positional deviation of the spray gun during the process of laying it flat and erecting it, so that the bottom of the spray gun gradually aligns with the bottom groove 202, reducing the accuracy requirements for manual alignment. The inner wall of the bottom groove 202 is vertically flush with the inner wall of the positioning groove 30, ensuring that the lower end of the spray gun is completely in contact with the stop block 3 when it is erected, avoiding uneven force due to misalignment. In addition, the tilt angle of the shaped groove 201 needs to be designed according to the diameter and weight of the spray gun (e.g., 30° to 45°) to ensure smooth guidance and avoid the spray gun getting stuck due to an excessively large angle.

[0025] Furthermore, in a specific implementation, the flatcar 2 provided in this embodiment of the present invention is provided with a locking block 21 that engages with the upper part of the spray gun in a flat position. The locking block 21 engages with the upper part of the spray gun and forms a "double-fixed" structure with the guide groove plate 4 at the lower end, preventing the spray gun from sliding laterally due to vibration during flat transport.

[0026] Furthermore, in a specific implementation, the aforementioned locking block 21 provided in this embodiment of the present invention includes a base 211 and a V-shaped support leg 212. The spray gun achieves self-centering by contacting the inclined surfaces on both sides of the V-shaped opening of the support leg 212, and can achieve positioning correction even if there is a certain offset at the upper end of the spray gun during the lowering process.

[0027] Furthermore, in a specific implementation, the aforementioned locking block 21 provided in this embodiment of the present invention is linearly slidably connected to the flatcar 2 along its length. Specifically, the locking block 21 can slide and engage with a groove provided on the flatcar 2, enabling the locking block 21 to move linearly along the flatcar 2. By sliding the position of the locking block 21, the support requirements of spray guns of different lengths can be adapted, ensuring the stability of both ends when laid flat.

[0028] Furthermore, in a specific implementation, a buffer pad 22 is provided at the bottom of the aforementioned card block 21 provided in this embodiment of the present invention. Specifically, the buffer pad 22 absorbs the vibration energy when the flatcar 2 moves, preventing the spray gun from rigidly colliding with the card block 21 and causing surface damage.

[0029] Furthermore, in specific implementation, the flatcar 2 provided in this utility model embodiment is provided with a plurality of buffer pads 22 that are in contact with the spray gun at intervals along its length direction, so as to distribute the weight of the spray gun and avoid deformation caused by local stress concentration.

[0030] Furthermore, in a specific implementation, the buffer pad 22 provided in this embodiment of the present invention is made of polyurethane material. The surface of the buffer pad 22 is provided with a concave arc surface that fits against the outer wall of the spray gun, and anti-slip textures are provided on the concave arc surface. Specifically, the curvature of the concave arc surface matches the curvature of the outer wall of the spray gun, increasing the contact area and improving stability. The anti-slip textures increase the coefficient of friction between the spray gun and the flatbed 2, further preventing longitudinal sliding of the spray gun during sudden stops or accelerations.
