Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a processing device for I-beams used in diaphragm wall joints. Background Technology

[0002] With urban development, more and more subways are being built to alleviate traffic congestion. Stations are mostly constructed using the open-cut method. This method requires the construction of diaphragm wall retaining structures first. Diaphragm walls are usually constructed in sections, and steel plates are welded into I-beams to connect the diaphragm walls. The I-beam joints are then welded to the reinforcing cage to form a whole before hoisting.

[0003] Traditional cutting and welding mainly involves workers using gas cutters to cut steel plates and then welding them manually. This method is prone to problems such as uneven cuts and incomplete welds. In addition, it requires multiple people to operate, resulting in high labor costs and low construction efficiency. Therefore, how to quickly cut and weld steel plates into I-beams while ensuring construction safety is the key to the construction of diaphragm wall reinforcement cages. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a processing device for I-beams used in diaphragm wall joints, which reduces the input of personnel, improves construction efficiency, and ensures construction quality and progress.

[0005] To achieve the above technical effects, this utility model provides a processing device for I-beams used in diaphragm wall joints, comprising:

[0006] Steel plate to be processed;

[0007] The crane track is provided on the steel plate to be processed;

[0008] A cutting trolley is mounted on the traveling track and can travel along the length of the traveling track. The cutting trolley is equipped with an oxy-acetylene torch that is adjustable in angle to cut the steel plate to be processed to form the web and flange of the I-beam.

[0009] A welding trolley is mounted on the traveling track and can travel along the length of the traveling track. The welding trolley is equipped with a welding torch that is adjustable in angle for welding the web and flange of the steel plate to be processed to form an I-beam after the gas cutting torch cuts the steel plate to be processed to form the web and flange of the I-beam.

[0010] A welding fixing assembly for fixing the web and flange during welding includes a base plate disposed at the bottom of the web and arranged parallel to the web, and multiple stiffening plates are fixedly connected between each pair of the base plate, the web, and the flange.

[0011] Preferably, a first adjusting rod is fixedly connected to the top of the cutting trolley, the direction of the first adjusting rod is parallel to the surface of the steel plate to be processed, and the top of the gas cutting gun is rotatably mounted on the first adjusting rod on the side relatively away from the cutting trolley.

[0012] After the gas cutting torch adjusts its angle with the surface of the steel plate to be processed by rotating, it simultaneously cuts the steel plate to be processed as the cutting carriage moves on the trolley track, thereby forming the web plate and the wing plate.

[0013] Preferably, the trolley track during welding is located on the web plate, a second adjusting rod is fixedly connected to the top of the welding trolley, the direction of the second adjusting rod is parallel to the surface of the web plate, and the top of the welding torch is rotatably mounted on the second adjusting rod on the side relatively away from the welding trolley.

[0014] After the welding torch is rotated to adjust the angle between itself and the web, it simultaneously welds the connection between the web and the flange as the welding trolley moves on the track, thereby forming the I-beam.

[0015] Preferably, the end of the second adjusting rod facing away from the welding trolley is fixedly connected with a ball bearing for abutting against the surface of the wing plate.

[0016] Preferably, a plurality of welded fixing rods are fixedly connected between the tops of the two flanges of the I-beam.

[0017] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0018] 1) Using a track during cutting can ensure that the steel plate is cut in a straight line, ensuring the quality of the finished product and reducing waste.

[0019] 2) Only one worker is needed to operate both cutting and welding. Automatic cutting and welding reduce manpower input and avoid uneven steel plate cutting and poor welding quality caused by human factors, thus improving construction efficiency.

[0020] 3) Automatic welding of I-beams can not only improve welding efficiency, but also ensure welding quality. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 5As shown, this utility model embodiment provides a processing device for I-beams used in diaphragm wall joints, including a steel plate to be processed 1, a traveling rail 3, a cutting trolley 4, a welding trolley 7, and a welding fixing assembly. The traveling rail 3 is mounted on the steel plate to be processed 1. The cutting trolley 4 is mounted on the traveling rail 3 and can travel along its length. An oxy-acetylene torch 6 is adjustablely mounted on the cutting trolley 4 for cutting the steel plate 1 to form the web 1101 and flange 102 of the I-beam. The welding trolley 7 can travel along the length of the traveling rail 3. The welding trolley 7 is mounted on the track 3 and is angle-adjustably equipped with a welding torch 13 for welding the web 101 and flange 102 of the steel plate 1 to be processed after the gas cutting torch 6 cuts the steel plate 1 to be processed to form the I-beam. The welding fixing assembly is used to fix the web 101 and flange 102 during welding. The welding fixing assembly includes a base plate 9 located at the bottom of the web 101 and arranged parallel to the web 101. Multiple stiffening plates 10 are fixedly connected between each pair of the base plate 9, the web 101, and the flange 102.

[0031] Furthermore, in this embodiment, a first adjusting rod 5 is fixedly connected to the top of the cutting carriage 4. The direction of the first adjusting rod 5 is parallel to the surface of the steel plate 1 to be processed, and the top of the gas cutting gun 6 is rotatably mounted on the first adjusting rod 5 on a side relatively away from the cutting carriage 4. Preferably, after the gas cutting gun 6 adjusts its angle with the surface of the steel plate 1 to be processed by rotation, it simultaneously cuts at the kerf 11 on the steel plate 1 to be processed as the cutting carriage 4 moves on the carriage track 3, thereby forming the web 101 and the wing 102.

[0032] Furthermore, in this embodiment, the welding carriage 7 is positioned on the web 101 via the travel track 3 during welding. Before cutting the steel plate 1 to be processed, the corresponding dimensions are measured so that the travel track falls on the corresponding area of ​​the web 101. A second adjusting rod 12 is fixedly connected to the top of the welding carriage 7. The direction of the rod 12 is parallel to the surface of the web 101, and the top of the welding torch 13 is rotatably mounted on the second adjusting rod 12 on a side relatively away from the welding carriage 7. Preferably, after adjusting the angle between the welding torch 13 and the web 101 by rotation, the welding torch 13 simultaneously welds the connection between the web 101 and the flange 102 (i.e., the weld seam 11) as the welding carriage 7 moves on the travel track 3, thereby forming an I-beam. It should be noted that in this embodiment, the gas cutting torch 6 and the first adjusting rod 5, and the welding torch 13 and the second adjusting rod 12 are rotatably connected by pins, and after being rotated to the corresponding angle, they are fixed by bolts (the technical solution of pin and bolt rotatable connection and fixing, as well as the working principle and structural components of the welding carriage and the cutting carriage are existing technologies known to those skilled in the art, and therefore will not be described in detail).

[0033] Please see Figures 3 to 5 As shown, in this embodiment, a ball bearing 14 is fixedly connected to the end of the second adjusting rod 12 facing away from the welding carriage 7, for abutting against the surface of the wing plate 102. The ball bearing 14 ensures smooth movement of the second adjusting rod 12 on the wing plate 102. By setting the traveling speed of the welding carriage 7 and the welding machine current, efficiency is improved while ensuring welding quality. Preferably, multiple welding fixing rods 8 are fixedly connected between the tops of the two wing plates 102 of the I-beam.

[0034] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model 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 this utility model, the scope of which is defined by the appended claims and their equivalents.
