Description

Technical Field

[0001] This invention relates to the field of construction safety technology, and in particular to a fire-fighting hopper for high-altitude operations. Background Technology

[0002] Construction site safety management is a core aspect of engineering project management. High-altitude welding operations (such as welding of steel structures in high-rise buildings, bridge bearings, and internal welding of wind turbine towers) present significant challenges to safety control due to their height, limited space, and complex slag fall paths. If the high-temperature welding slag generated during welding is not effectively collected, it can easily ignite flammable materials such as scaffolding safety nets, insulation materials, and wood below, causing fires. Furthermore, flying slag can injure workers below or damage equipment and pipelines, resulting in safety hazards and economic losses.

[0003] The most common type of fire-catching bucket on the market is the chain-suspended type. Its structure is usually a metal bucket body with hanging rings welded to the four corners. After connecting the hanging rings with iron chains, the top of the iron chains is fixed to the aerial work platform, scaffold crossbar, or steel structure component, so that the fire-catching bucket is suspended directly below the welding point. It is difficult to set up in narrow spaces, which affects the work of operators. At the same time, the iron chain is a flexible connector. When exposed to natural wind, welding vibration, or disturbance from people walking below in the high-altitude working environment, the bucket body is prone to shaking and rotation, causing welding slag to splash out from the edge of the bucket body. Utility Model Content

[0004] The purpose of this new design is to weld hanging rings at the four corners of the bucket body. After connecting the hanging rings with iron chains, the top of the iron chains is fixed to the aerial work platform, scaffold crossbar, or steel structure component, so that the fire-receiving bucket is suspended directly below the welding point. This is difficult to arrange in narrow spaces, affecting the work of operators. At the same time, the iron chains are flexible connectors. In the high-altitude working environment, when subjected to natural wind, welding vibrations, or disturbances from people walking below, the bucket body is prone to shaking and rotation, causing welding slag to splash and overflow from the edge of the bucket body.

[0005] The technical solution of this invention: a high-altitude fire-fighting hopper, comprising: a galvanized iron sheet fire-fighting hopper, with connecting blocks welded and installed on both sides of the galvanized iron sheet fire-fighting hopper, and a steel reinforcement support frame installed above the connecting blocks. The steel reinforcement support frame is generally L-shaped, with a movable groove on the top of the steel reinforcement support frame, and a clamping assembly installed inside the movable groove. A sealing plate is movably installed above the galvanized iron sheet fire-fighting hopper, and protruding posts are provided on adjacent surfaces of the two steel reinforcement support frames. The sealing plate is positioned by the protruding posts.

[0006] Optionally, the clamping assembly includes a rebar clamping surface, a guide rod is installed inside the movable groove, the top of the rebar clamping surface is movably sleeved on the surface of the guide rod, and a spring is provided inside the movable groove and on the surface of the guide rod, with the front end of the spring fixedly connected to the rebar clamping surface.

[0007] Optionally, the bottom end of the steel bar clamping surface is set to be arc-shaped.

[0008] Optionally, the surface of the steel bar clamping surface near the galvanized iron sheet fire-receiving hopper is set as a plane.

[0009] Optionally, two extension blocks are symmetrically installed at the rear end of the galvanized iron sheet fire-receiving hopper, and a rotating shaft is rotatably installed between the two extension blocks. The rotating shaft is fixedly connected to the rear of the sealing plate.

[0010] Optionally, a pressing plate is fixedly installed at the other end of the rotating shaft.

[0011] Optionally, the horizontal height of the rotating shaft is higher than that of the galvanized iron sheet fire-fighting hopper.

[0012] Optionally, baffles are provided on both sides of the middle end of the galvanized iron sheet fire-receiving hopper, the baffles corresponding to the protruding post, a through hole is provided inside the connecting block, and a T-shaped rod is fixedly provided at the bottom of the steel bar support frame, the surface of the T-shaped rod movably passing through the through hole.

[0013] Optionally, the end of the galvanized iron sheet fire-fighting hopper opening is designed to be inclined.

[0014] Optionally, all fixed connections of the device are welded connections.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] The galvanized iron sheet fire-catching bucket of this device can be hung on the side of the construction operation and can also meet the requirements of fire catching. It can avoid the obstruction of the surrounding structure and ensure that the galvanized iron sheet fire-catching bucket is accurately aligned with the path of the falling welding slag. It is suitable for complex high-altitude scenarios where vertical hanging is not possible and space is narrow.

[0017] By setting up an L-shaped steel bar support frame and clamping components, a dual fixing function can be achieved, which improves stability compared to traditional devices and eliminates safety accidents such as chain breakage and bucket falling.

[0018] All fixed parts of the device are connected by welding, forming an integrated structure through metal fusion, which provides higher connection strength compared to detachable connections such as bolts and clips.

[0019] By setting up a sealing plate, a complete protective space can be formed in the galvanized iron sheet welding hopper. When the galvanized iron sheet welding hopper is moved, the welding slag will not splash or slip, thus avoiding secondary safety accidents.

[0020] The convex column enables vertical locking of the sealing plate. When vertically locked, the opening of the galvanized iron fire hopper is fully open, and the sealing plate is not easily loosened, making sealing plate locking simple. Attached Figure Description

[0032] The high-altitude fire-fighting hopper includes: a galvanized iron sheet fire-fighting hopper 1; connecting blocks 2 welded to both sides of the galvanized iron sheet fire-fighting hopper 1; a steel reinforcement support frame 3 installed above the connecting blocks 2; the steel reinforcement support frame 3 being L-shaped; a movable groove 4 opening at the top of the steel reinforcement support frame 3; a clamping assembly inside the movable groove 4; a sealing plate 10 movably installed above the galvanized iron sheet fire-fighting hopper 1; and protruding posts 13 on adjacent surfaces of the two steel reinforcement support frames 3. The sealing plate 10 is positioned by the protruding posts 13. This device allows the galvanized iron sheet fire-fighting hopper 1 to be hung on the side of the work area, thus meeting the requirements for fire-fighting. This design avoids obstruction from surrounding structures and ensures that the galvanized iron sheet fire-catching hopper 1 is precisely aligned with the path of the falling welding slag. By setting up an L-shaped steel support frame 3 and clamping components, the device can be doubly fixed, improving stability compared to traditional devices and preventing safety accidents such as chain breakage and hopper falling. At the same time, by setting up a sealing plate 10, a complete protective space can be formed for the galvanized iron sheet fire-catching hopper 1, and under the action of the protruding column 13, the sealing plate 10 can be vertically locked. When vertically locked, the opening of the galvanized iron sheet fire-catching hopper 1 is fully open, and the position of the sealing plate 10 is not easy to loosen.

[0033] Example 1

[0034] See Figures 1 to 4 The clamping assembly includes a rebar clamping surface 6, a guide rod 5 installed inside the movable groove 4, the top of the rebar clamping surface 6 being movably sleeved on the surface of the guide rod 5, and a spring 7 being provided inside the movable groove 4 and located on the surface of the guide rod 5, with the front end of the spring 7 being fixedly connected to the rebar clamping surface 6.

[0035] The bottom end of the steel bar clamping surface 6 is set in an arc shape;

[0036] The surface of the steel bar clamping surface 6 near the galvanized iron sheet fire hopper 1 is set as a plane;

[0037] In this embodiment, the operator lifts the entire device upwards, making the overall height of the rebar clamping surface 6 higher than the high-altitude steel beam to be fixed. At this time, the spring 7 in the movable groove 4 is in a naturally extended state. Then, the corner of the top of the rebar support frame 3 is aligned vertically with the steel beam, and then the entire device is pulled downwards. At this time, the arc-shaped surface at the bottom of the rebar clamping surface 6 gradually approaches the end of the steel beam away from the galvanized iron fire-receiving hopper 1. As the pulling action continues, the bottom of the rebar clamping surface 6, under the squeezing action of the steel beam, will move along the guide rod 5 in the direction away from the galvanized iron fire-receiving hopper 1, while simultaneously compressing the spring 7 sleeved on the surface of the guide rod 5. Continue pulling the device downwards until the top plane of the rebar support frame 3 is completely pressed against the top surface of the steel beam. At this point, the device completes vertical positioning and locking (the top of the rebar support frame 3 is in contact with the top of the steel beam, restricting the device from moving up and down). Simultaneously, the spring 7 releases the stored restoring force, pushing the rebar clamping surface 6 to move in the opposite direction (towards the steel beam). This causes the vertical surface of the rebar clamping surface 6 to continuously press against the end of the steel beam away from the galvanized iron sheet fire hopper 1, forming a horizontal clamping and locking. Finally, the device is firmly locked onto the steel beam through the double fixing structure in both the vertical and horizontal directions, without any risk of shaking or displacement.

[0038] Example 2

[0039] Two extension blocks 9 are symmetrically installed at the rear end of the galvanized iron sheet fire-receiving hopper 1. A rotating shaft 11 is rotatably installed between the two extension blocks 9. The rotating shaft 11 is fixedly connected to the rear of the sealing plate 10.

[0040] A pressing plate 12 is fixedly installed at the other end of the rotating shaft 11;

[0041] The horizontal height of the rotating shaft 11 is higher than that of the galvanized iron fire-receiving hopper 1;

[0042] The galvanized iron sheet fire hopper 1 has baffles 14 on both sides of the middle end, the baffles 14 correspond to the protruding post 13, the connecting block 2 has a through hole inside, and the bottom of the steel bar support frame 3 is fixedly provided with a T-shaped rod 8, the surface of the T-shaped rod 8 has a through hole.

[0043] In this embodiment, after the device is fixed to the high-altitude steel beam by the clamping assembly, the operator lifts the main body of the galvanized iron fire-receiving bucket 1 upwards. Since the through hole inside the connecting block 2 and the T-shaped rod 8 at the bottom of the steel support frame 3 are in a movable through-fitting manner, the lifting force will cause the connecting block 2 to slide upwards along the T-shaped rod 8, and the galvanized iron fire-receiving bucket 1 will rise as a whole. The core purpose of this step is to make the height of the baffle 14 higher than the protrusion 13 on the steel support frame 3, so as to reserve vertical operating space for the subsequent rotation of the sealing plate 10 and avoid premature interference between the baffle 14 and the protrusion 13. Next, the pressing plate 12 is fixed to the other end of the rotating shaft 11. The operator presses the pressing plate 12 downwards, and drives the rotating shaft 11 to rotate around the two extension blocks 9 through the lever principle. Since the rear of the sealing plate 10 is fixedly connected to the rotating shaft 11, the rotation of the rotating shaft 11 will synchronously drive the sealing plate 10 to move. Flip the plate upwards and press the pressing plate 12 continuously until the sealing plate 10 is completely perpendicular to the galvanized iron fire hopper 1. At this time, the protruding column 13 on the steel support frame 3 is exactly below the baffle 14 (parallel in the vertical direction and unobstructed in the horizontal direction). Then, keeping the sealing plate 10 in a vertical state, the operator cancels the lifting force on the galvanized iron fire hopper 1. The galvanized iron fire hopper 1 slides down along the T-shaped rod 8 due to its own weight. The connecting block 2 drives the baffle 14 to descend simultaneously. When the galvanized iron fire hopper 1 descends to the natural equilibrium position, the height of the baffle 14 is exactly the same as the height of the protruding column 13, and the protruding column 13 is in front of the baffle 14. At this time, the protruding column 13 forms a horizontal obstruction and limit on the baffle 14, and the baffle 14 cannot move forward, thereby restricting the sealing plate 10 from rotating forward, and finally achieving a stable lock of the sealing plate 10 in a vertical state.

[0044] Example 3: The end of the galvanized iron sheet fire-receiving bucket 1 at the opening is set in an inclined shape;

[0045] The inclined surface expands the effective receiving range and guides the inclined welding slag into the bucket. The inclined edge eliminates the sharp risk of the right-angle opening. When operators lift and adjust the fire receiving bucket at high altitude, it is less likely to be injured when their hands or bodies come into contact with the edge of the opening, reducing the personal safety risk of high-altitude operations. At the same time, the inclined surface facilitates the edge wiping operation when cleaning the fire receiving bucket later.

[0046] All fixed connections of the device are welded connections;

[0047] Welded connections form an integrated structure through metal fusion. In high-altitude operations, the galvanized iron sheet fire bucket 1 needs to withstand its own weight, the impact of welding slag, and other forces for a long time, thus effectively ensuring the overall rigidity.

[0048] The above specific embodiments are merely one optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
