Description

Technical Field

[0001] The utility model relates to the field of welding processing auxiliary tools, in particular to a welding fire receiving device for steel members. Background Technique

[0002] In recent years, with the booming development of large public building steel structures, a batch of super high-rise buildings with unique structural shapes have emerged. When steel beams of steel structures are connected to embedded parts and steel columns on concrete walls, T-shaped butt welds are usually involved. During the trimming and welding of the welds, a large amount of sparks and scraps are usually generated. The sparks and scraps are prone to falling, which may cause fires and pose a great threat to ground personnel and facilities. It is necessary to use a special and effective fire receiving device to prevent the sparks and scraps from falling and ensure construction safety.

[0003] The traditional solution is to use a suspended fire receiving basin, which is usually a square container made of thin steel plates and suspended below the section steel. However, for I-beams, this traditional suspended fire receiving basin cannot comprehensively prevent sparks generated during the welding of I-beams, resulting in sparks splashing everywhere, posing a safety hazard. Moreover, the suspended position needs to be set at the connection of two I-beams, but this connection is also the welding position, which will affect the construction of the welding process.

[0004] At the same time, in actual processing, there are usually multiple welding points, and it is necessary to process multiple parts of the same workpiece or multiple different workpieces. Therefore, it is necessary to design a flexible fire receiving device to adapt to different welding environments and improve the convenience of construction. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a welding fire receiving device for steel members, which solves the problems of sparks and scraps falling during the repair of welds and the welding process, posing a safety hazard, and the poor construction convenience of the traditional fire receiving device.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is: a welding fire receiving device for steel members, slag collection boxes are symmetrically arranged on both sides of the I-beam, two first clamping plates are symmetrically arranged above the opening on the upper surface of the slag collection box, both ends of the second clamping plate are respectively connected to the first clamping plates at one end of the slag collection boxes on both sides through wing nuts, and a lifting mechanism is arranged on one side of the second clamping plate to drive the slag collection box to move on the I-beam.

[0007] In the preferred solution, the first clamping plate is a Z-shaped plate, and both ends of the second clamping plate are also Z-shaped structures. The distal ends of the Z-shaped structures of the first clamping plate and the second clamping plate are connected through wing nuts, and the proximal ends are abutted against both sides of the flange plate of the I-beam.

[0008] In the preferred solution, the structure of the lifting mechanism is: one end of the lifting rope is connected to the lower end of the first pulley, and the other end bypasses the second pulley and exits from the upper end of the first pulley.

[0009] In a preferred embodiment, the second pulley is rotatably connected to one side of the second clamping plate through a rotating shaft.

[0010] In a preferred embodiment, the first pulley is arranged at any fixed height above the I-beam through a hanging bracket, and one end of the lifting rope is pulled to lift the slag collection box.

[0011] In a preferred embodiment, the slag collection box is a box body with openings on both sides. A slot is provided at the lower end of the inner opening, and the slot is slidably connected to the flange plate of the I-beam. The lower surface of the opening abuts against the web of the I-beam.

[0012] In a preferred embodiment, an inclined surface is further provided on the lower surface inside the slag collection box.

[0013] The utility model provides a welding fire-catching device for steel members. Slag collection boxes are symmetrically arranged on both sides of the I-beam. Two first clamping plates are symmetrically arranged above the openings on the upper surfaces of the slag collection boxes. Both ends of the second clamping plate are respectively connected to the first clamping plates at one ends of the slag collection boxes on both sides through butterfly bolts. A second pulley is arranged on one side of the second clamping plate, and a first pulley is arranged above the second pulley. One end of the lifting rope is connected to the lower end of the first pulley, and the other end bypasses the second pulley and then winds out from the upper end of the first pulley. By pulling the lifting rope, the slag collection box is driven to move on the I-beam, solving the problems that sparks and residual materials fall during the repair of weld seams and the welding process, posing potential safety hazards, and the traditional fire-catching device has poor construction convenience.

[0024] Embodiment 1

[0025] As Figures 1 - 8 shown, for a steel member welding fire-catching device, slag collection boxes 2 are symmetrically arranged on both sides of the I-beam 1. Above the openings on the upper surfaces of the slag collection boxes 2, two first clamping plates 3 are symmetrically arranged. Both ends of the second clamping plate 4 are respectively connected to the first clamping plates 3 at one end of the slag collection boxes 2 on both sides through wing nuts 5. A lifting mechanism 6 is arranged on one side of the second clamping plate 4 to drive the slag collection box 2 to move on the I-beam 1.

[0026] In a preferred solution, the first clamping plate 3 is a Z-shaped plate, and both ends of the second clamping plate 4 are also of Z-shaped structures. The distal ends of the Z-shaped structures of the first clamping plate 3 and the second clamping plate 4 are connected through wing nuts 5, and the proximal ends are abutted against both sides of the flange plate of the I-beam 1. It provides a shrinking space for the bolt connection between the two clamping plates, facilitating the clamping of the I-beam 1, and at the same time can adapt to I-beams with different flange plate thicknesses, and the fire-catching device can be used in multiple situations.

[0027] In a preferred solution, the structure of the lifting mechanism 6 is: one end of the lifting rope 601 is connected to the lower end of the first pulley 602, and the other end bypasses the second pulley 603 and then exits from the upper end of the first pulley 602.

[0028] In a preferred solution, the second pulley 603 is rotatably connected to one side of the second clamping plate 4 through a rotating shaft 7.

[0029] In a preferred solution, the first pulley 602 is arranged at any fixed height above the I-beam 1 through a hanging bracket 8, and one end of the lifting rope 601 is pulled to lift the slag collection box 2.

[0030] By setting a movable pulley-fixed pulley lifting mechanism, the movement of the fire-catching device is labor-saving, and it is symmetrically arranged on both sides, making the upward force symmetric and uniform.

[0031] In a preferred solution, the slag collection box 2 is a box body with openings on both sides. A slot 201 is arranged at the lower end of the inner opening, and the slot 201 is slidably connected to the flange plate of the I-beam 1, and the lower surface at the opening is abutted against the web of the I-beam 1. The slag collection box 2 is closely attached to the I-beam 1 to prevent the remaining materials and sparks from falling.

[0032] In a preferred solution, an inclined surface is also arranged on the inner lower surface of the slag collection box 2. It is convenient to collect the remaining materials and sparks, preventing them from concentrating on the inner surface of the I-beam 1 and affecting the movement of the fire-catching device, or leaking out from the contact surface gap.

[0033] In the application, the I-beam 1 is clamped between the slag collection boxes 2 on both sides. Its flange plates are respectively inserted into the slots 201. Both sides of one end flange plate are respectively clamped between two first clamping plates 3 and a second clamping plate 4, and are fixed at the target position of the I-beam 1 through the butterfly bolt 5. When moving, the first pulley 602 is arranged at any fixed height above the I-beam 1 through the hanging bracket 8, and one end of the lifting rope 601 is pulled to lift the slag collection box 2.

[0034] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
