[0002] Ships are made up of tens of thousands of parts and are related to almost every industrial sector. In addition to the unique hull construction technology, shipbuilding also involves various fields such as machinery, electrical, metallurgy, construction, chemistry and even arts and crafts; therefore, shipbuilding is a comprehensive technology based on all industrial technologies, reflecting a country's industrial technology level; due to the different navigation areas, tasks and requirements of ships, ship products have the characteristics of many varieties and small production batches; in order to produce rhythmically and shorten the manufacturing cycle, shipyards must have careful production management and technical management from the acceptance of orders to the completion and delivery of ships. The materials used in shipbuilding are of many varieties and large quantities, among which steel is the largest.

[0003] When manufacturing ship plate units in the shipbuilding industry, it is necessary to weld the large blade plates needed inside the hull on the tire frame. Generally, the large blade plates are placed on a fixed tire frame and then welded by corresponding welding equipment; however, the existing welding tire frame is generally a fixed structure. When adjusting the placement angle of the welding tire frame, a pad is generally placed at one end of the bottom of the welding tire frame to raise it, thereby achieving an angle change; however, this method is difficult to accurately control the placement angle and requires repeated corrections, which is difficult to operate and labor-intensive.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1:

[0027] Working principle: By rotating the first hand wheel 38, the bidirectional threaded rod 36 is rotated, so that the two movable seats 34 move toward or away from each other on the bidirectional threaded rod 36, which makes the corresponding first connecting rod 33 and the second connecting rod 35 cooperate with each other and rotate outward or inward synchronously, which makes the end of the cross plate 1 rotate upward or downward, thereby realizing the adjustment of the placement angle of the cross plate 1; the whole process is simpler to operate, with high operating precision, and greatly reduces the amount of manual labor.

[0028] Embodiment 2:

[0029] When the broadsword plate is placed on a welding frame for welding, when the welding head of the welding equipment contacts the broadsword plate, a certain force will be exerted on the broadsword plate. However, the welding frame of the prior art does not clamp the broadsword plate, which will cause a certain deviation of the broadsword plate, thereby affecting the welding quality.

[0032] By turning the second hand wheel 53, the worm 52 is rotated, so that the worm wheel 54 and the rotating seat 55 rotate synchronously, and the connecting block 561 drives the fixed plate 562 to adjust the position, so that the clamping seat 564 is located above the corresponding large knife plate; then the clamping bolt 563 is turned to move the clamping seat 564 downward and clamp the large knife plate, which can prevent the large knife plate from being displaced during the welding process and affecting the welding quality.

[0033] Embodiment 3:

[0034] In the prior art, the height of the welding equipment is fixed. However, in the actual operation process, the installation height of the welding equipment needs to be changed, which requires the welding equipment to be disassembled and installed on another welding frame that meets the height requirement. The whole process is cumbersome and complicated, which greatly reduces the welding efficiency.

[0035] See also Figure 1-4As another preferred embodiment of the present invention, the difference from Embodiment 1 or Embodiment 2 is that it also includes a mounting seat 6, the mounting seat 6 is located at the end of the horizontal plate 1, a second support seat 7 is fixedly installed on the top of the mounting seat 6, a height adjustment mechanism 8 is installed on the inner side of the second support seat 7, and a welding equipment tray 9 is installed at the output end of the height adjustment mechanism 8; the welding equipment tray 9 is used to install corresponding welding equipment.

[0036] The height adjustment mechanism 8 includes a bevel gear 81, a third hand wheel 82, a bevel gear plate 83, a screw rod 84, a rotating shaft 85 and a partition plate 86; the bevel gear 81 is rotatably mounted inside the second support seat 7 through a pin shaft, the third hand wheel 82 is coaxially fixedly connected to the bevel gear 81 and is located outside the second support seat 7, and the third hand wheel 82 is used to drive the bevel gear 81 to rotate; the partition plate 86 is fixedly mounted inside the second support seat 7, and a bevel gear plate 83 is rotatably mounted on the partition plate 86, and the bevel gear plate 83 and the bevel gear 81 are meshed with each other. 81 can drive the bevel gear disc 83 to rotate; the screw rod 84 passes through the bevel gear disc 83 and is threadedly connected to the bevel gear disc 83. The top end of the screw rod 84 passes through the top wall of the second support seat 7 and can slide in the second support seat 7. The screw rod 84 can be relatively displaced with the bevel gear disc 83 when the bevel gear disc 83 rotates; the rotating shaft 85 is rotatably installed on the top of the screw rod 84, and the top of the rotating shaft 85 is fixedly connected to the end of the welding equipment tray 9; the rotating shaft 85 is used to drive the welding equipment tray 9 to rotate on the horizontal plane to adjust the horizontal angle of the welding equipment.

[0037] By rotating the third hand wheel 82, the bevel gear 81 is rotated, thereby rotating the bevel gear disc 83, which causes the screw rod 84 and the bevel gear disc 83 to be displaced accordingly, thereby driving the welding equipment tray 9 upward or downward, thereby achieving height adjustment of the welding equipment tray 9, and thus achieving height adjustment of the welding equipment; the entire process can be completed without disassembling the welding equipment, and the operation is simpler.
