Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure construction, and in particular to a composite beam beveling device. Background Technology
[0002] Drilling platforms and oil production platforms are common offshore engineering equipment, typically employing a beam-column-plate structure with extensive use of composite beams. Composite beams offer advantages such as high load-bearing capacity and rigidity. Common composite beam types on drilling and production platforms include T-beams and box beams. Before welding the composite beams to the deck, pre-treatment by cutting and beveling the web plates is necessary. Traditionally, this is done manually with a flame cutter. Based on industry averages, one person can complete approximately 30 meters per shift (8 hours / day). Furthermore, due to human fatigue, unstable working conditions, and other natural factors, the cut bevels are inevitably uneven, exceeding tolerances and requiring repairs and rework.

[0004] A composite beam beveling device includes a base, a movable seat on the base, a cutting device on the movable seat, a cutting head connected to the cutting device via a cantilever, a connecting arm on the movable seat, a guide groove at one end of the connecting arm, and the guide groove being fitted onto the web of the composite beam; the movable seat moves linearly on the base, the guide groove moves along the web, and the cutting head moves relative to the web and cuts.
[0005] Furthermore, a linear track is provided on the base, and track wheels are provided at the bottom of the movable seat, allowing the movable seat to move linearly on the linear track of the base via the track wheels.
[0006] Furthermore, the height of the top surface of the movable seat is adjustable, and the cutting device is located on the top surface of the movable seat.
[0007] Furthermore, the cutting head is rotatably mounted on the cantilever to adjust the cutting angle of the cutting head.
[0008] Furthermore, the connecting arm and the movable base are detachably and fixedly connected.
[0009] The beneficial effects of this utility model are as follows:
[0010] The device includes a base, a movable seat mounted on the base, a cutting device mounted on the movable seat, a cutting head connected to the cutting device via a cantilever, a connecting arm mounted on the movable seat, and a guide groove at one end of the connecting arm. The guide groove is fitted onto the web of the composite beam. In use, the movable seat is driven to move linearly on the base, and the movable seat drives the guide groove to move along the web, ensuring that the web and the movable seat move in parallel directions. Then, the movable seat drives the cutting head to move relative to the web and cut a bevel. Using this device, beveling can be completed automatically, with high processing efficiency. Moreover, the instrument automatically cuts in a straight line, producing high-quality bevels that do not require rework. Attached Figure Description

[0017] See Figure 1In this embodiment, the composite beam beveling device includes a base 100, a movable seat 101 on the base 100, a cutting device 102 fixedly mounted on the movable seat 101, and a cutting head 104 connected to the cutting device 102 via a cantilever 103. Preferably, the cutting device 102 is an automatic flame cutting gun, and the cutting head 104 is a welding gun. A connecting arm 105 is mounted on the movable seat 101, and a guide groove 106 is provided at one end of the connecting arm 105. The guide groove 106 is fitted onto the web 201 of the composite beam 200. In use, the movable seat 101 moves linearly on the base 100, and then drives the guide groove 106 to move along the web 201 via the connecting arm 105 to ensure that the web 201 is parallel to the moving direction of the movable seat 101. At the same time, the movable seat 101 drives the cutting device 102, the cantilever 103, and the cutting head 104 to move linearly relative to the web 201 together, and the cutting head 104 cuts the web to form a neat bevel. This device automatically completes beveling, improving work efficiency. Furthermore, the cooperation between the movable seat 101 and the guide groove 106 ensures that the cutting head 104 cuts in a straight line, resulting in high-quality bevels that do not require rework.
[0018] More specifically, in this embodiment, a linear track 107 is provided on the base 100, and a track wheel 108 is provided at the bottom of the movable seat 101. The movable seat 101 moves linearly on the linear track 107 of the base 100 via the track wheel 108, ensuring the stability and accuracy of the linear movement of the movable seat 101 and preventing deviation.
[0019] Furthermore, in this embodiment, the height of the top surface of the movable seat 101 is adjustable, which can be set by adjusting the height using a lead screw or pad block as in the prior art; the cutting device 102 is set on the top surface of the movable seat 101, so that the height of the cantilever 103 and the cutting head 104 can be adjusted to adapt to the processing of the bevel of the composite beam 200 of different heights.
[0020] Furthermore, in this embodiment, the cutting head 104 is rotatably mounted on the cantilever 103. The preferred method for mounting the cutting head 104 is the torsional joint connection of the robotic arm in the prior art, so as to precisely adjust the cutting angle of the cutting head 104 and adapt to the processing of bevels with different angles.
[0021] More specifically, in this embodiment, the connecting arm 105 and the movable seat 101 are detachably fixedly connected, for example, the connecting arm 105 and the movable seat 101 are threaded or snap-fitted in the prior art, so that the guide groove can be adapted to be installed on the web plate 201 at different heights.
