Description

Technical Field

[0001] This utility model relates to the technical field of track welding protection equipment, specifically a safety protection device for crane track welding. Background Technology

[0002] Due to prolonged operation, the multi-functional overhead crane tracks in the raw material workshop of an electrolytic aluminum plant experienced joint breakage, necessitating repairs. Previously, track repairs primarily relied on manual welding, fishplate connections, or clamp connections. Manual welding is inefficient, requires highly skilled welders, and is hampered by the strong magnetic field and high temperatures in the raw material workshop, making welding difficult, quality control challenging, and inconsistent welding times. While fishplate and clamp connections are convenient, discontinuous joints easily cause wear on wheels and axles, affecting equipment lifespan and indirectly leading to greater production downtime losses. Furthermore, subsequent maintenance is arduous. To improve efficiency, overcome the drawbacks of conventional track welding methods, extend equipment maintenance cycles, and increase economic benefits, aluminothermic welding technology, typically used in railway tracks, was applied to the docking construction of crane tracks in industrial plants through technological breakthroughs.

[0003] However, applying railway-grade aluminothermic welding technology to the docking construction of crane tracks in industrial plants presents several inconveniences. First, the crane tracks are located at a high position and the surrounding space is small, leaving little room for workers to stand. Additionally, the railway-grade aluminothermic welding technology requires preheating and pouring of the tracks during welding operations, which generates flames that could affect the safety of workers. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection device for welding overhead crane tracks. By setting up a protective kit, high-density iron mesh, handles and sand mold clamps, it solves the problem that the overhead crane tracks are located at a high position and the surrounding space is small, which limits the standing space for workers during construction. At the same time, the aluminothermic welding technology for railway tracks requires preheating and pouring of the track during welding operations, which will generate flames and affect the safety of construction personnel.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a safety protection device for welding overhead crane tracks, including a protective kit, wherein multiple high-density iron meshes are fixedly connected to the inner wall of the protective kit, an operating hole is opened in the middle of the upper surface of the protective kit, handles are welded to both sides of the protective kit, a heat-insulating pad is fitted to the top of the surface of the handle, and a frame is fitted to the surface of the handle.

[0006] Preferably, a rotating handle is welded to the bottom end of the sleeve, and a bearing A is sleeved on the bottom end of the rotating handle.

[0007] Preferably, the rotating handle is rotatably connected to the sand mold clamp via a bearing A, and the surface of the sleeve frame is provided with a sliding groove, with the handle slidably connected inside the sliding groove.

[0008] Preferably, one of the sand mold clamps has an L-shaped rod welded to one side, and the other sand mold clamp has a straight rod welded to the other side.

[0009] Preferably, one end of the straight rod is welded with a sleeve, and the L-shaped rod is inserted into the sleeve.

[0010] Preferably, a bearing seat is fixedly connected to one side of the L-shaped rod, and a screw is rotatably connected inside the bearing seat via a B bearing, the screw being threaded into the inside of the straight rod.

[0011] Preferably, a limiting block is fixedly connected to one end of the sleeve frame, and the limiting frame is snapped onto the surface of the sleeve frame.

[0012] This utility model provides a safety protection device for welding overhead crane tracks, which has the following beneficial effects:

[0013] In use, the broken track is straightened and aligned, and a sand mold is installed. After fixing the sand mold with a sand mold clamp, it is sealed with mud. Then, the handle is pulled up to put the protective kit on the sand mold, and a preheating operation is performed. After preheating, the sand mold is poured using a crucible and flux pack. After pouring, the equipment and sand mold are removed, and then the lumps are pushed off and polished. This equipment can block the flames during track preheating, making it easier for personnel to approach and work. At the same time, it also avoids the splashing of molten steel during pouring, which could cause personnel injury, thus improving the safety of personnel during operation.

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a safety protection device for crane track welding, including a protective kit 1. Multiple high-density iron meshes 2 are fixedly connected to the inner wall of the protective kit 1. Through the high-density iron meshes 2, the flames sprayed upward from the sand mold during preheating can be blocked, thus blocking sparks and small particles and improving safety. A working hole 3 is opened in the middle of the upper surface of the protective kit 1. At the same time, the operation is carried out through the working hole 3, which also reduces the possibility of molten steel splashing and injuring workers during subsequent pouring. Handles 4 are welded on both sides of the protective kit 1. A heat insulation pad 5 is sleeved on the top of the surface of the handle 4, and a frame 6 is sleeved on the surface of the handle 4.

[0024] A rotating handle 7 is welded to the bottom end of the sleeve 6, and a bearing A 8 is sleeved on the bottom end of the rotating handle 7.

[0025] The rotating handle 7 is rotatably connected to the sand mold clamp 9 via bearing A 8. The surface of the sleeve 6 is provided with a groove, and the handle 4 is slidably connected to the inside of the groove.

[0026] After the sand mold is fixed by the sand mold clamp 9, the frame 6 can be rotated by rotating the handle 7, which makes it easy for personnel to install the protective kit 1 on the sand mold by gripping the handle 4.

[0027] One of the sand mold fixtures 9 has an L-shaped rod 10 welded to one side, and the other sand mold fixture 9 has a straight rod 11 welded to the other side. A sleeve 12 is welded to one end of the straight rod 11. The L-shaped rod 10 is inserted into the sleeve 12. A bearing seat 13 is fixedly connected to one side of the L-shaped rod 10. A screw 14 is rotatably connected to the inside of the bearing seat 13 through a B bearing. The screw 14 is threaded into the inside of the straight rod 11.

[0028] After the L-shaped rod 10 and the straight rod 11 are connected through the sleeve 12, the two are moved towards the middle by rotating the screw 14, thereby moving the sand mold clamps 9 on both sides and achieving the effect of fixing the sand mold.

[0029] One end of the sleeve 6 is fixedly connected to a limit block, and the surface of the sleeve 6 is snapped with a limit frame 15.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
