Description

Technical Field

[0001] The invention relates to the technical field of steel platform welding, and in particular to a railway maintenance single-layer steel platform welding flipping device and a welding method thereof. Background Art

[0002] The railway maintenance single-layer steel platform, as an important infrastructure for railway maintenance operations, is composed of beams, columns, plates and other components made of steel. The various parts are connected by welds, screws or rivets. It has a flexible design and is easy to assemble and disassemble. It provides a stable working platform for maintenance personnel and supports the placement and operation of various maintenance equipment.

[0003] After searching, a Chinese patent with publication number CN116352349A discloses a railway maintenance single-layer steel platform welding flipping device and a welding method thereof, wherein the flipping mechanism includes a groove and a fixed plate, wherein the groove is opened on the top of the processing table, and two of the grooves are provided, and a cylinder is rotatably connected inside the groove, and the fixed plate is fixedly connected to the front side of the support table, and two of the fixed plates are provided, and a first cross bar is rotatably connected inside the two fixed plates, and a connecting arm is fixedly connected to the end of the first cross bar, and the connecting arm is rotatably connected to the cylinder. The present invention relates to the field of steel platform welding technology. The railway maintenance single-layer steel platform welding and flipping device and welding method thereof solve the problem that the existing steel platform is heavy in weight and the weight is increased after welding, which makes it difficult to carry after welding, by using the groove, the fixed plate, the cylinder, the first cross bar, the connecting arm, the movable arm, the flipping plate and the buffer mechanism in coordination. However, in actual application scenarios, for the single-layer steel platform required for railway maintenance, due to its complex structure and the fact that it is usually assembled from multiple large steel components through welding technology, the overall weight of these platforms is often very large. When the cylinder is used as the flipping power source, the internal seal of the cylinder is easily worn during repeated high-load flipping operations, resulting in unstable cylinder pressure, which in turn affects the accuracy and stability of the flipping. In addition, due to the gravity and inertia of the steel platform itself, unexpected shaking or deviation may occur during the flipping process.

[0057] A welding method for a single-layer steel platform welding flip device for railway maintenance, comprising the following steps:

[0058] Step 1: First, fix the steel platform component in an appropriate position to ensure that it is stable and does not shake. Turn on the electric push rod to extend it, so that the adjustment frame is separated from the fixed frame, and prepare for the installation of the steel platform component. Lift the steel platform component to be installed to the inside of the adjustment frame to ensure that the component is placed stably. Then, shorten the electric push rod to slide the adjustment frame along the fixed frame until the adjustment frame can be tightly covered on the edge of the steel platform component, completing the initial positioning and installation of the component;

[0059] Step 2: Place the components to be spliced ​​on the steel platform components in the adjustment frame and perform welding operations. After completing the welding on one side, prepare to flip it over;

[0060] Step 3: Before flipping, turn off the electromagnet. Under the action of the spring, the guide block and the electromagnet are reset, the lock of the rotating shaft is released, and the flip motor is started. The fixed frame and the adjustment frame are driven to rotate through the rotating shaft to realize the flipping of the steel platform component. After flipping to the required angle or completing the flipping, turn on the electromagnet again to make it adsorbed on the outer wall of the rotating shaft. In this process, the positioning rod is inserted into the positioning groove on the fixed plate through the sliding of the guide block and the guide groove, and the action of the connecting rod, so as to firmly fix the angle of the rotating shaft;

[0061] Step 4: During the welding process, the two sliding frames are located at the top and bottom of the guide opening respectively. The extension plate is adjusted to fit the top and bottom surfaces of the adjustment frame. When the flip motor is running, the support rod and the driving bevel gear are driven to rotate through the mechanical transmission device (rotating shaft, driven wheel, synchronous belt, etc.), and then the two driven bevel gears are driven to rotate in the opposite direction. The sliding rod is driven to slide along the fixed frame through the transmission rod and the connecting gear, so that the sliding frame can adjust its position adaptively during the flipping process to avoid affecting the flipping process, and the horizontal position of the adjustment frame can be calibrated;

[0062] Step 5: During the flipping process, the fixed frame can be automatically knocked with the help of a knocking device (composed of a half gear, a rotating rod, a connecting frame and a knocking head) to help separate welding slag and other debris. After the flipping is completed, the other side of the steel platform component can be welded.

[0063] Beneficial effects of the present invention:

[0064] 1. This type of railway maintenance single-layer steel platform welding and flipping device and welding method thereof, by setting a locking component, the setting of the flipping motor cooperates with the linkage of the rotating shaft, the fixed frame and the adjusting frame, can easily flip the steel platform component, thereby realizing welding of components at multiple angles, improving the comprehensiveness and flexibility of welding, and the combination of the electromagnet with the guide block, the positioning rod and other mechanisms realizes the firm locking of the rotating shaft angle, avoids the safety hazard caused by loose angle during welding or flipping, and improves the safety of the operation.

[0065] 2. This type of railway maintenance single-layer steel platform welding and flipping device and its welding method, by setting contrast components and transmission components, and coordinating the sliding frame and the extension plate, enables the device to be adaptively adjusted according to steel platform components of different sizes, thereby enhancing the versatility and practicality of the device. At the same time, by adjusting the degree of fit between the adjustment frame and the extension plate, the staff can intuitively judge whether the adjustment frame is in a horizontal state, which provides strong support for subsequent precise welding.

[0066] 3.

[0081] When in use, the steel platform can be fixed first, the electric push rod 11 can be opened and extended to separate the adjusting frame 5 from the fixed frame 4, and then the steel platform component can be hoisted to the inner side of the adjusting frame 5, and the electric push rod 11 can be shortened so that the adjusting frame 5 can slide along the fixed frame 4 and the adjusting frame 5 can be covered on the edge of the steel platform component, and the installation of the steel platform component can be completed. The staff can place the components to be spliced ​​on the steel platform component and weld them.

[0083] When the components are welded or flipped at a certain angle, the fixed frame 4 and the adjustment frame 5 can be locked. Specifically, when the angle of the adjustment frame 5 and the fixed frame 4 needs to be locked, the electromagnet 75 can be turned on. The rotating shaft 3 is made of metal material. Therefore, the electromagnet 75 can be directly adsorbed on the outer wall of the rotating shaft 3 when it is turned on.

Then, the flip motor 6 can be turned on to flip the steel platform component through the rotating shaft 3, the fixed frame 4 and the adjusting frame 5.

[0084] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the comparison component includes: a mounting plate 81, the mounting plate 81 is fixedly mounted on the side position of the top surface of the welding seat 1; a guide port 82, the guide port 82 is opened at the end of the mounting plate 81 away from the welding seat 1; a sliding frame 83, the sliding frame 83 is slidably mounted on the inner side wall of the guide port 82; an extension plate 84, the extension plate 84 is slidably mounted on the inner side wall of the sliding frame 83; a transmission plate 89, the transmission plate 89 is fixedly mounted on the bottom surface of the end of the sliding frame 83 away from the extension plate 84, and the comparison component also includes: two slide grooves 85, two slide grooves The groove 85 is symmetrically provided on the inner side wall of the sliding frame 83; two sliders 86 are symmetrically fixedly installed on the extension plate 84, and the sliders 86 are slidably connected with the sliding groove 85; a plurality of limiting grooves 87 are distributed in a linear array and provided on the inner side wall of the sliding frame 83 above the sliding groove 85; a limiting rubber strip 88 is fixedly installed on the side wall of the extension plate 84, the limiting rubber strip 88 is adapted to the limiting groove 87, and the cross-sectional shapes of the limiting groove 87 and the limiting rubber strip 88 are both semicircular;

[0085] During the welding process of the steel platform, the two sliding frames 83 are respectively located at the top and bottom of the two guide openings 82, and are respectively fitted with the top and bottom surfaces of the two adjustment frames 5.

[0086] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, the transmission assembly includes: a support rod 91, which is rotatably mounted on the side wall of the welding seat 1 located below the fixed ring plate 71; a driving bevel gear 92, which is fixedly mounted on the end of the support rod 91 away from the welding seat 1; two driven wheels 93, which are respectively fixedly sleeved on the rotating shaft 3 and the support rod 91; a synchronous belt 94, which is sleeved on the two driven wheels 93; two brackets 95, which are symmetrically fixedly mounted on the end of the welding seat 1 away from the flip motor 6; two transmission rods 96, which are respectively rotatably mounted on the inner side walls of the two brackets 95; two driven bevel gears 97, which are respectively fixedly mounted on the ends of the two transmission rods 96 close to each other, and the two driven bevel gears 97 are respectively fixedly mounted on the ends of the two transmission rods 96 close to each other.

[0087] When the flip motor 6 is running to flip the fixed frame 4 and the adjustment frame 5, the support rod 91 can be driven to rotate through the rotating shaft 3, the driven wheel 93 and the synchronous belt 94. When the support rod 91 rotates, the driving bevel gear 92 can be driven to rotate. The driving bevel gear 92 is meshed with the two driven bevel gears 97, so the two driven bevel gears 97 can be driven to rotate, and the two driven bevel gears 97 can rotate in opposite directions. During the rotation of the driven bevel gears 97, the connecting gear 98 can be driven to rotate through the transmission rod 96.

Through the degree of fit between the adjusting frame 5 and the two extension plates 84, the staff can intuitively judge whether the adjusting frame 5 is in a horizontal state, so as to carry out precise welding later.

[0088] like Figures 5 to 7 As shown, the knocking assembly includes: a mounting frame 101, the mounting frame 101 is fixedly mounted on the side wall of the fixed frame 4; a rotating rod 102, the rotating rod 102 is rotatably mounted on the inner side of the mounting frame 101; a half gear 103, the half gear 103 is fixedly sleeved on the rotating rod 102; a torsion spring 104, the torsion spring 104 is sleeved on one end of the rotating rod 102, and the two ends of the torsion spring 104 are respectively fixedly connected to the mounting frame 101 and the rotating rod 102; a connecting frame 105, the connecting frame 105 is fixedly sleeved on the rotating rod 10 2 is away from the end of the torsion spring 104; a knocking head 106, which is fixedly mounted on the end of the connecting frame 105 away from the rotating rod 102; a connecting ring plate 107, which is fixedly mounted on the end of the vertical plate 2 away from the flip motor 6; a plurality of teeth 108, which are divided into a plurality of groups, each group having the same number of teeth 108, and a plurality of groups of teeth 108 are distributed in a ring array and fixedly mounted on the side wall of the connecting ring plate 107, and the teeth 108 are meshed with the half gear 103;

When the half gear 103 rotates, it can drive the rotating rod 102 and the connecting frame 105 to rotate, and compress the torsion spring 104. At this time, the knocking head 106 can be separated from the fixed frame 4. When the fixed frame 4 rotates to the point where the half gear 103 is separated from the second tooth 108, the rotating rod 102, the half gear 103 and the connecting frame 105 can be reversed under the reaction force of the torsion spring 104, so that the fixed frame 4 is knocked by the knocking head 106, so that during the flipping of the steel platform component, continuous knocking is used to separate the welding slag and other debris attached to the frame from the steel platform workpiece, ensuring the neatness of the component after welding is completed.

[0090] The present invention also discloses a welding method for a railway maintenance single-layer steel platform welding flip device, comprising the following steps:

[0091] Step 1: First, fix the steel platform component in an appropriate position to ensure that it is stable and does not shake. Turn on the electric push rod 11 to extend it, so that the adjustment frame 5 is separated from the fixed frame 4, and prepare for hoisting the steel platform component. Hoist the steel platform component to be installed to the inner side of the adjustment frame 5 to ensure that the component is placed stably. Then, shorten the electric push rod 11 to make the adjustment frame 5 slide along the fixed frame 4 until the adjustment frame 5 can be tightly covered on the edge of the steel platform component, completing the preliminary positioning and installation of the component;

[0092] Step 2: Place the components to be spliced ​​on the steel platform components in the adjustment frame 5 and perform welding operations. After completing the welding on one side, prepare to flip it over;

[0093] Step 3: Before flipping, turn off the electromagnet 75. Under the action of the spring 76, the guide block 73 and the electromagnet 75 are reset, the locking of the rotating shaft 3 is released, and the flipping motor 6 is started. The fixed frame 4 and the adjusting frame 5 are driven to rotate through the rotating shaft 3 to realize the flipping of the steel platform component. After flipping to the required angle or completing the flipping, turn on the electromagnet 75 again to make it adsorbed on the outer wall of the rotating shaft 3. In this process, the positioning rod 77 is inserted into the positioning groove 79 on the fixed plate 78 through the sliding of the guide block 73 and the guide groove 72, and the action of the connecting rod 74, so as to firmly fix the angle of the rotating shaft 3.

[0094] Step 4: During the welding process, the two sliding frames 83 are respectively located at the top and bottom of the guide opening 82. By adjusting the extension plate 84, it is made to fit with the top and bottom surfaces of the adjustment frame 5. When the flip motor 6 is running, the support rod 91 and the driving bevel gear 92 are driven to rotate through the mechanical transmission device (rotating shaft 3, driven wheel 93, synchronous belt 94, etc.), and then the two driven bevel gears 97 are driven to rotate in the opposite direction. The sliding rod 910 is driven to slide along the fixed frame 99 through the transmission rod 96 and the connecting gear 98, so that the sliding frame 83 can adjust its position adaptively during the flipping process to avoid affecting the flipping process, and the horizontal position of the adjustment frame 5 can be calibrated;

[0095] Step 5: During the flipping process, the fixed frame 4 can be automatically knocked with the help of a knocking device (composed of a half gear 103, a rotating rod 102, a connecting frame 105 and a knocking head 106) to help separate debris such as welding slag. After the flipping is completed, the other side of the steel platform component can be welded.
