Traffic safety engineering construction frame welding device and welding method

Abstract

This invention discloses a welding equipment and method for a construction scaffold in traffic safety engineering, relating to the field of construction scaffold welding technology. It includes a support mechanism comprising a workbench with two sets of support rods fixed to its top. A U-shaped frame is fixed to the top of each set of support rods, and a pedal frame is located on top of the U-shaped frame. The two sides of the U-shaped frame are tightly fitted against the inner wall of the pedal frame to position it. Two right-angle limiting frames are fixed to the top of the workbench. This invention changes the position of the welding points of the steel mesh, wrapping the steel mesh around the pedal frame with the welding points positioned below. This distributes the force partially on both sides of the pedal frame, reducing the tensile force directly acting on the welding position, reducing weld breakage, increasing the service life of the welding points, making the steel mesh more robust, reducing construction hazards, and preventing feet from stepping on the welding points, thus avoiding corrosion caused by dirt enveloping the welding points.

Description

Technical Field

[0001] This invention relates to the field of construction scaffold welding technology, and in particular to a welding equipment and welding method for construction scaffolds used in traffic safety engineering. Background Technology

[0002] Construction scaffolding, also known as scaffolding, is a working platform erected to ensure the smooth progress of various construction processes. It can be classified according to its location (external scaffolding, internal scaffolding); according to materials (wooden scaffolding, bamboo scaffolding, steel pipe scaffolding); and according to its structural form (pole scaffolding, bridge scaffolding, frame scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, climbing scaffolding).

[0003] The scaffolding consists of two parts: a support frame and movable platform steps. The platform steps are placed on the support frame for workers to step on during construction. The platform steps are composed of a platform frame and a steel mesh. The steel mesh is laid flat and welded onto the platform frame to fill the gaps in the platform frame, aiming to reduce the amount of steel pipe used in the platform frame and thus save steel pipe. The welding points between the steel mesh and the platform frame are located on top. Because workers often work on top, their shoes and tools will come into direct contact with the welding points. Direct contact can easily cause corrosion to the welding points, and friction from tools can easily damage the welding points. Furthermore, when the welding points are located on top, the tensile force generated when gravity acts directly on the steel mesh will be directly transmitted to the welding points, making the welding points prone to breakage, resulting in a shorter service life and a certain degree of danger. Summary of the Invention

[0004] This invention proposes a welding equipment and welding method for construction scaffolds in traffic safety engineering to address the aforementioned shortcomings in the prior art.

[0005] To achieve the upper frame, the pedal frame is located at the top of the U-shaped frame, and the two sides of the U-shaped frame are close to the inner wall of the pedal frame to position the pedal frame. Two right-angle limit frames are fixed on the top of the worktable.

[0006] Also includes:

[0007] Furthermore, the processed component, which is mounted on the support mechanism, includes a pedal frame and a steel mesh;

[0008] The steel mesh is located at the top of the pedal frame, and the length of the steel mesh is the same as the length of the pedal frame, while the width of the steel mesh is greater than the width of the pedal frame.

[0009] Furthermore, a welding point coincidence mechanism, which is installed on top of the support mechanism, is used for the welding points of the steel mesh to contact the bottom welding points of the pedal frame;

[0010] The welding point overlap mechanism includes two square columns fixed to one side of the movable plate and one side of the movable plate, respectively. A top plate is fixed to the top of the two square columns. A limiting rod is sleeved inside the top plate. A pressure plate is fixed to the bottom of the two limiting rods. A spring is sleeved outside the limiting rod. The top end of the spring is fixedly connected to the top plate. The bottom end of the spring is fixedly connected to the pressure plate. Multiple limiting pressure plates are fixed on both sides of the pressure plate.

[0011] The welding point overlap mechanism also includes side plates fixed to the bottom of the square column. Two sets of steel mesh deformation structures are installed between the two side plates. The steel mesh deformation structure includes a shell with an upward opening. The top of the shell has a ramp. The two ramps are mirror images of each other. Multiple ball bearings are rotatably connected to the ramps. Multiple springs are fixed to the inner wall of the bottom of the shell. An inner plate is fitted inside the shell. The top of the spring is fixedly connected to the inner plate. Slide plates are fixed to both sides of the shell. Two sliding grooves are opened on the opposite side of each of the two side plates. An inner rod is fixed to the inner wall of the sliding groove. The slide plate is fitted inside the inner rod. A spring is fitted outside the inner rod. One end of the spring is fixedly connected to the slide plate. The other end of the spring is fixedly connected to the inner wall of the sliding groove.

[0012] The steel mesh is pressed to the bottom of the pedal frame by the welding point overlap mechanism, so that the connection point between the steel mesh and the pedal frame is located at the bottom. This avoids damage to the welding point due to frequent stepping and also greatly improves the firmness of the steel mesh and extends the service life of the pedal.

[0013] Furthermore, the lifting mechanism is connected to the support mechanism and the welding point overlap mechanism, and is used to drive the welding point overlap mechanism to move up and down;

[0014] The lifting mechanism includes a reciprocating screw 1 rotatably connected to the top of the worktable, a one-way gear 1 is installed on the outside of the reciprocating screw 1, and a moving plate 1 is threaded onto the outside of the reciprocating screw 1.

[0015] A guide rod is fixed to the top of the workbench, and a movable plate is sleeved on the outside of the guide rod.

[0016] Furthermore, a wave welding mechanism, which is installed above the support mechanism and below the workpiece, is used for welding the welding points of the workpiece.

[0017] The wave welding mechanism includes two mounting plates fixed to the bottom of the workbench, a reciprocating screw two rotatably connected between the two mounting plates, a bevel gear one fixed to the outside of the reciprocating screw two, a guide rod two fixed between the two mounting plates, a movable frame threaded onto the outside of the reciprocating screw two, the movable frame being sleeved on the outside of the guide rod two, a rotating shaft one rotatably connected to the top of the workbench, a one-way gear two mounted on the top of the rotating shaft one, a bevel gear two fixed to the bottom of the rotating shaft one, and the bevel gear two meshing with the bevel gear one;

[0018] Two telescopic rods are fixed to the top of the mobile frame. A welder is fixed to the top of the telescopic rod. A spring four is sleeved on the outside of the telescopic rod. The top of the spring four is fixedly connected to the welder, and the bottom is fixedly connected to the mobile frame. A connecting plate is fixed to the bottom of the two welders on the side that is close to each other. A rotating shaft two is rotatably connected to the opposite side of the two connecting plates. Two wave frames are fixed to the top of the workbench. The rotating shaft two is located at the bottom of the wave frames.

[0019] The wave welding mechanism uses a wave frame to move the welder up and down during the lateral movement of the welder to weld the steel mesh and the treadmill frame.

[0020] Furthermore, a drive mechanism, which is connected to the lifting mechanism and the wave welding mechanism, is used to drive the lifting mechanism and the wave welding mechanism to operate;

[0021] The drive mechanism includes a motor fixed to the top of the workbench. A gear is fixed to one end of the output shaft of the motor. One side of the gear meshes with a one-way gear, and the other side of the gear meshes with a two-way gear.

[0022] A welding device for a construction scaffold in traffic safety engineering includes the following steps:

[0023] S1: Install the workpiece onto the support mechanism;

[0024] S2: The lifting mechanism drives the welding point alignment mechanism to move down, straightening the bent steel mesh and pressing it tightly against the top of the pedal frame;

[0025] S3: The lifting mechanism continues to drive the welding point aligning mechanism downward so that the steel mesh wraps around the pedal frame, making the welding points of the steel mesh coincide with the welding points of the pedal frame;

[0026] S4: The steel mesh and the pedal frame are welded together using a wave welding mechanism;

[0027] S5: The lifting mechanism drives the welding point alignment mechanism to move upward and reset. Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This invention uses a welding point overlap mechanism to press the side of the steel mesh to the bottom of the pedal frame, so that the connection point between the steel mesh and the pedal frame is located below. This avoids damage to the welding points due to frequent stepping, and also greatly improves the firmness of the steel mesh and extends the service life of the pedal.

[0029] 2. This invention uses a wave welding mechanism to move the welder up and down during the lateral movement of the welder to weld the steel mesh and the pedal frame.

[0030] In summary, this equipment features a novel design and simple operation. By altering the position of the steel mesh weld points, wrapping the steel mesh around the pedal frame with the weld points positioned below, the force is distributed across both sides of the pedal frame. This reduces the tensile force directly applied to the weld points, minimizing weld breakage, increasing the service life of the weld points, making the steel mesh more robust, reducing construction hazards, and preventing feet from stepping on the weld points, thus avoiding corrosion caused by dirt accumulation.

[0061] Example 2: Refer to Figures 2-9 This embodiment provides a welding device for a construction scaffold in traffic safety engineering, based on Embodiment 1, and includes the following steps:

[0062] S1: Install the machined part 2 onto the support mechanism 1;

[0063] S2: The lifting mechanism 3 drives the welding point aligning mechanism 4 to move down, straightening the bent steel mesh and pressing it tightly against the top of the pedal frame;

[0064] S3: The lifting mechanism 3 continues to drive the welding point aligning mechanism 4 to move down, so that the steel mesh wraps around the pedal frame, and the welding points of the steel mesh coincide with the welding points of the pedal frame.

[0065] S4: The steel mesh and the pedal frame are welded together by the wave welding mechanism 5;

[0066] S5: The lifting mechanism 3 drives the welding point overlap mechanism 4 to move upward and reset.

[0067] Working principle:

[0068] First, place the pedal frame on top of the two U-shaped frames (13). The U-shaped frames (13) limit the pedal frame. Then, place the steel mesh on top of the pedal frame from one side. One side of the steel mesh contacts the right-angle limit frame (14). At this time, the workpiece (2) is installed.

[0069] The starting motor (61) drives the gear (62) to rotate forward. The forward rotation of the gear (62) satisfies the direction of rotation of the one-way gear (32) driving the reciprocating screw (31) to rotate. The reciprocating screw (31) drives the moving plate (33) to move down. The moving plate (33) drives the welding point overlap mechanism (4) to move down. After the pressure plate (44) and the limiting pressure plate (45) come into contact with the steel mesh, they press it onto the pedal frame, so that the bent steel mesh is straightened by force and sticks tightly to the pedal frame. After the pressure plate (44) and the limiting pressure plate (45) are limited by the pedal frame, they cannot continue to move down.

[0070] Then the square column (418) pushes the side plate (46), inner rod (48), spring three (49) and steel mesh deformation structure downward. Because of the support of the limit plate (45), spring three (49) is always in a stretched state. When the limit plate (45) is limited, the steel mesh deformation structure continues to move downward and offset. When it moves downward, the bottom contacts the top of the steel mesh that exceeds the pedal frame. If it continues to move downward, the excess steel mesh will bend and stick to the pedal frame. At this time, the pedal frame still keeps spring three (49) in a stretched state. In the stretched state, the width of the bent steel mesh is greater than the height of the pedal frame. When the top of the steel mesh deformation structure is lower than the bottom of the pedal frame, the pedal frame cannot continue to limit the steel mesh deformation structure. Spring three (49) pulls the two steel mesh deformation structures closer to each other, bending the excess steel mesh tightly against the bottom of the steel mesh frame. The inner plate (415) pushes the top steel mesh, making the steel mesh in close contact with the pedal frame. At this time, the moving plate one (33) moves to the bottom thread of the reciprocating screw one (31).

[0071] The starting motor (61) drives the gear (62) to reverse. The reverse rotation of the gear (62) satisfies the direction of rotation of the one-way gear two (56) driving the rotating shaft one (55). The rotation of the rotating shaft one (55) drives the bevel gear two (57) to rotate. The rotation of the bevel gear two (57) drives the bevel gear one (54) and the reciprocating screw two (53) to rotate. The reciprocating screw two (53) causes the moving frame (59) to drive the telescopic rod (510), spring four (511), welder (512), connecting plate (513) and The second rotating shaft (514) moves. During the movement, the wave frame (58) limits the second rotating shaft (514), causing the second rotating shaft (514) to move along the bottom of the wave frame (58). During the movement, the spring contracts and releases. When the welder (512) moves to the highest point, it will contact the edge of the steel mesh and weld the edge of the steel mesh to the bottom of the pedal frame. After the moving frame (59) moves to the end of the wire, it returns to the original position. When resetting, the welder (512) does not work. After resetting, the welding is completed.

[0072] The starting motor (61) drives the gear (62) to rotate forward, causing the moving plate (33) that has moved to the end of the screw to move upward, thereby pulling the steel mesh deformation structure upward. When it moves upward, the inner plate (415) is blocked by the top processing part (2). When the force increases to a certain extent, the second spring (414) is compressed, and the inner plate (415) retracts into the interior of the housing (411). Then, when the housing (411) is pulled upward, the third spring (49) will be pulled away from both sides due to the ramp (416) and the ball (417). Then it will be located on both sides of the processing part (2) again. If it continues to move upward, it will be located on both sides of the limiting pressure plate (45). If it continues to move upward, the limiting pressure plate (45) and the pressure plate (44) will move upward. After moving to the top end of the reciprocating screw (31), the reset is completed.

[0073] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
