Description

Technical Field

[0001] This utility model relates to the field of pipeline construction, and in particular to a movable material platform for pipeline welding operations. Background Technology

[0002] During pipeline welding construction, workers typically need to carry welding machines, welding materials, auxiliary tools, and other equipment along the pipeline. To improve construction efficiency, existing technologies often employ mobile fixtures to carry welding equipment, reducing the burden of manual handling. For example, Chinese patent CN215880444U discloses a mobile trolley fixture for carrying welding equipment. This fixture is supported on the pipeline by a load-bearing frame and uses rollers to contact the outer wall of the pipeline, enabling it to move axially along the pipeline.

[0003] However, because the pipe has a cylindrical structure, a smooth surface, and no fixed support points, especially when the load-bearing frame is stationary, if there is no human support, the center of gravity of the load-bearing frame is easily shifted when the load on both sides of the load-bearing frame is uneven (such as uneven distribution of welding equipment and material weight), which can lead to tilting or even slippage.

[0004] Therefore, there is an urgent need for a mobile platform for pipeline welding operations with higher stability, adjustability, and safety to improve construction efficiency and ensure operational safety. Utility Model Content

[0005] The purpose of this utility model is to overcome the technical problem that when existing mobile tooling for pipe welding is stationary, the smooth surface of the pipe and the lack of fixed support points make it easy for the center of gravity to shift when the load on both sides of the load-bearing frame is uneven, which can lead to tilting or even slipping and poses a safety hazard. The present invention provides a movable material platform for pipe welding operations.

[0006] This utility model provides a movable material platform for pipe welding operations, including a support frame that can straddle a pipe, and horizontal plates are provided on both sides of the support frame.

[0007] A limiting rod is vertically mounted on the horizontal plate and can move in the vertical direction. The bottom of the limiting rod can abut against the ground.

[0008] This utility model discloses a movable material platform for pipe welding operations. When the platform is stationary, the limiting rods on the two horizontal plates move downwards, causing the bottom of the limiting rods to abut against the ground, providing support to both sides of the load-bearing frame. This counteracts the tendency of the load-bearing frame to slide on the pipe surface and prevents the load-bearing frame from tilting or slipping due to uneven load. When the material is moving, the limiting rods can move upwards and detach from the ground, avoiding interference with the movement of the load-bearing frame along the length of the pipe. This achieves dual-mode switching between moving and stationary operation, significantly improving the stability of the material platform under uneven load conditions, fundamentally avoiding the risk of slippage, and ensuring construction safety.

[0009] Preferably, the horizontal plate is provided with a sleeve, the sleeve passes vertically through the horizontal plate, and the limiting rod is threadedly connected to the sleeve.

[0010] The limit rod is raised and lowered precisely by means of threaded adjustment, which allows for flexible adjustment of the support length according to the ground height, ensuring stable contact with the ground when the material table is stopped. The sleeve structure enhances the vertical guidance of the limit rod and prevents deflection.

[0011] Preferably, a handwheel is provided at the top of the limiting rod.

[0012] Construction workers can quickly and manually adjust the height of the limit bar using a handwheel, without the need for additional tools, thus improving work efficiency.

[0013] Preferably, the bottom of the limiting rod is provided with a circular pad, the diameter of which is larger than the diameter of the limiting rod.

[0014] Increase the contact area with the ground to distribute pressure and prevent the limit rod from sinking into soft ground; at the same time, enhance the anti-overturning ability and reduce the risk of slippage, especially when the load is uneven.

[0015] Preferably, the supporting frame includes a top plate, and support frames are respectively provided on both sides of the top plate, and the top plate and the two support frames are arranged to form a gate shape.

[0016] The portal-shaped structure straddles the pipeline, forming a stable support space. The top plate is used to place equipment, and the support frame provides lateral rigidity. The overall structure is simple and the stress is reasonable.

[0017] Preferably, the support frame includes two columns, the top of which is connected to the top plate, and the bottom outer side of which is connected to the horizontal plate.

[0018] The upright serves as a vertical load-bearing component, while the horizontal plate extends the lateral support surface, facilitating tool placement and providing an installation base for the limit rod, thus forming a stable bottom frame.

[0019] Preferably, a first reinforcing rib is provided between the column and the top plate, and the column, the top plate and the first reinforcing rib form a triangle.

[0020] Triangular reinforcement is used at the connection points between the top plate and the columns to reduce welding stress and prevent the frame from deforming due to load or vibration from movement.

[0021] Preferably, a second reinforcing rib is provided between the column and the horizontal plate, and the column, the horizontal plate and the second reinforcing rib form a triangle.

[0022] Strengthen the connection between the uprights and the horizontal plates, further disperse the reaction force when the limit rod is supported, and avoid bending of the horizontal plates or cracking of the welds.

[0023] Preferably, the bottom surface of the top plate is provided with a first roller, and the inner side of the column is provided with a second roller.

[0024] The first roller rolls along the top of the pipe, while the second roller fits against the side of the pipe, forming a three-point contact (top + sides), which ensures smooth movement and reduces the risk of the material table tipping over.

[0025] Preferably, the top of the top plate is provided with an annular limiting frame, and the annular limiting frame is provided with a plurality of partitions, which divide the space inside the annular limiting frame into a plurality of storage areas.

[0026] The frame prevents equipment / tools from slipping, and the dividers divide the space into dedicated storage areas (such as welding guns, welding materials, etc.) to achieve classified storage and improve construction convenience and safety.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a movable material platform for pipe welding operations. When the material platform is stationary, the limiting rods on the two horizontal plates are moved downwards so that the bottom of the limiting rods abuts against the ground, forming support on both sides of the bearing frame, counteracting the tendency of the bearing frame to slide on the pipe surface, and preventing the bearing frame from tilting or slipping due to uneven load. 2. This utility model provides a movable material platform for pipe welding operations. When the material platform moves, the limiting rod can move upward and detach from the ground to avoid interfering with the movement of the bearing frame along the length of the pipe. 3. This utility model provides a movable material platform for pipe welding operations. Through the design of a liftable limit rod, it realizes the dual-mode switching of movement and stationary position, which significantly improves the stability of the material platform under uneven load conditions, fundamentally avoids the risk of slippage, and ensures construction safety.
