DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-4 A safe fixing structure for manufacturing ships includes a transmission box 1, a transverse screw 2 is rotatably connected to the transmission box 1, a transverse nut 3 is slidably provided in the transmission box 1, a base 5 is fixedly connected to the side wall of the transmission box 1, a servo motor 4 is fixedly installed on the base 5, and the output shaft of the servo motor 4 is fixedly connected to the transverse screw 2.

[0026] A supporting and fixing mechanism for fixing the ship is fixed on the transverse nut 3, and the supporting and fixing mechanism includes a supporting seat 31, a supporting plate 8, a supporting mechanism 6 and an adjusting mechanism. A groove 7 is provided at the upper end of the support seat 31, and the support plate 8 is rotatably set in the groove 7. The supporting mechanism 6 is used to support the ship, and the adjusting mechanism is used to adjust the angle of the support plate 8. The adjusting mechanism includes a gear 16, a rack 17, an adjusting screw 20, an adjusting nut 18 and a limiting rod 19, wherein the gear 16 is fixedly connected to the side wall of the support plate 8, the rack 17 is slidably set in the groove 7 and meshes with the gear 16, the adjusting nut 18 is fixedly connected to the rack 17, and the adjusting nut 18 is threadedly connected to the adjusting screw 20, the limiting rod 19 is fixedly connected in the groove 7, the limiting rod 19 slides through the side wall of the adjusting nut 18, and a rocking wheel is rotatably connected to the side wall of the support seat 31, and the adjusting screw 20 is fixedly connected to the rocking wheel.

[0027] Reference Figure 4 The supporting mechanism 6 includes a supporting plate 601, a supporting rod 602, an L-shaped rod 604, and a connecting rod 603. One end of the L-shaped rod 604 is fixedly connected to the supporting plate 601, and the other end of the L-shaped rod 604 is fixedly connected to the upper end of the support base 31. One end of the supporting rod 602 is fixedly connected to the lower end of the supporting plate 601, and the other end of the supporting rod 602 is fixedly connected to the side wall of the support base 31. One end of the connecting rod 603 is fixedly connected to the supporting rod 602, and the other end of the connecting rod 603 is fixedly connected to the L-shaped rod 604. A protective spring is provided on the outer cover of the connecting rod 603. One end of the protective spring is fixedly connected to the L-shaped rod 604, and the other end of the protective spring is fixedly connected to the supporting rod 602. It should be noted that, by setting up the supporting mechanism 6 consisting of a supporting plate 601, a receiving rod 602, an L-shaped rod 604 and a connecting rod 603, the receiving rod 602 and the L-shaped rod 604 are respectively fixed on the side and upper end surface of the support seat 31, which can effectively share the force of the supporting plate 601, thereby greatly reducing the force of each component to provide a more stable support effect. At the same time, a connecting rod 603 is set to connect the supporting plate 601, the receiving rod 602 and the L-shaped rod 604 to form a more stable triangular structure, further enhancing the supporting stability of the supporting mechanism 6. In addition, by setting up a protective spring, when a component is broken or fractured, it can rely on its elastic effect to reduce the impact force of the downward pressure, and temporarily act as a connecting component, greatly reducing the dangerous effect of the hull 32 falling.

[0028] A storage groove 21 is provided on the side wall of the support seat 31, and a guardrail 27 is slidably connected to the storage groove 21. A rubber ball 28 is fixedly connected to one end of the guardrail 27, and a limit plate 29 is fixedly connected to the other end of the guardrail 27. A baffle 33 is fixedly connected to the side wall of the guardrail 27, and the baffle 33 is connected to the inner wall of the storage groove 21 through a limit spring. A control mechanism for controlling the movement of the guardrail 27 is installed in the storage groove 21.

[0029] Reference Figure 3 The control mechanism includes a safety pin 26 that slides through the sidewall of the guardrail 27. A telescopic sleeve 14 is fixedly connected to the support mechanism 6, and the safety pin 26 is fixedly connected to the telescopic portion of the telescopic sleeve 14 via a connecting rod 15. A storage slot 11 is defined in the sidewall of the transmission case 1. A telescopic airbag 12 is fixedly installed at the bottom of the storage slot 11. A rubber cover 13 is fixedly connected to the upper end of the telescopic airbag 12. Air is supplied to the telescopic airbag 12 by an air supply mechanism. It should be noted that the control mechanism not only allows the guardrail 27 to be quickly extended to intercept the hull 32 in the event that the support mechanism 6 breaks and causes it to fall, preventing it from falling and being damaged, but also provides the air supply mechanism with sufficient time to inject air into the telescopic airbag 12, causing it to expand and inflate, thereby promptly supporting and cushioning the falling hull 32.

[0030] Reference Figure 1 and Figure 3 The air supply mechanism includes an air storage tank 30, and the side wall of the support seat 31 is provided with an air guide groove 22. A sealing plug 23 is sealingly and slidably connected in the air guide groove 22. The air storage tank 30 is communicated with the air guide groove 22 through the air inlet pipe 24, and the air guide groove 22 is communicated with the telescopic airbag 12 through the air outlet pipe 25. The lower end of the safety pin 26 is fixedly connected to the sealing plug 23, and an exhaust hole 34 is provided at the inner bottom of the air guide groove 22. It should be noted that by providing the exhaust hole 34, the air below the sealing plug 23 can be connected to the outside. When the sealing plug 23 moves down, it is not hindered by air pressure, so that the sealing plug 23 can move down quickly. When the sealing plug 23 moves down, the exhaust hole 34 can also be blocked. In this way, the high-pressure air released from the air storage tank 30 is input into the air guide groove 22 through the air inlet pipe 24, and can be directly input into the telescopic airbag 12 through the air outlet pipe 25, thereby causing the telescopic airbag 12 to quickly expand and bulge.

[0031] Reference Figure 3The side wall of the support seat 31 is fixedly connected to an arc-shaped guide sleeve 10, and the side wall of the support plate 8 is fixedly connected to an arc-shaped guide rod 9, which is slidably disposed within the arc-shaped guide sleeve 10. It should be noted that the provision of the arc-shaped guide rod 9 and the arc-shaped guide sleeve 10 allows the support plate 8 to more smoothly adjust its tilt angle.

[0032] When using this device to fix the hull 32, you can refer to Figure 2 As shown, the hull is erected above the two supporting mechanisms 6, and then the adjusting screw 20 is driven to rotate by turning the rocker, and the adjusting nut 18 is limited by the limiting rod 19, so that the adjusting nut 18 can move left and right, which can drive the rack 17 to move, and then drive the gear 16 to rotate and the support plate 8 to rotate, so that the inclination angle of the support plate 8 can be adjusted, so that the side edge of the hull with different inclination angles can be matched. At this time, the servo motor 4 is controlled to drive the transverse screw 2 to rotate, which can move the transverse nut 3 and drive the support seats 31 on both sides to move toward each other, so that the two support plates 8 firmly fix the hull 32. At the same time, the supporting mechanism 6 is set to mainly support the weight of the hull 32, which can greatly enhance the safety effect of fixing the ship. At the same time, the supporting and fixing force of the hull 32 is dispersed on the entire surface of the support plate 8, which can effectively avoid the concave deformation of the hull during the fixing process.

[0033] If the supporting mechanism 6 breaks and causes the hull 32 to fall, the supporting mechanism 6 can act on the telescopic sleeve 14 when the hull 32 falls, causing the telescopic portion of the telescopic sleeve 14 to contract and move downward, thereby driving the safety pin 26 downward through the connecting rod 15. When the safety pin 26 moves downward, it will disengage from the guardrail 27. After the guardrail 27 loses the restraint of the safety pin 26, the limit spring can instantly push the limit plate 29 outward, and the limit plate 29 drives the guardrail 27 to move outward synchronously, thereby blocking the hull 32 from falling to the ground and being damaged, and also preventing the hull 32 from hitting nearby personnel. At the same time, the soft rubber ball 28 on the outside of the guardrail 27 can provide a certain cushioning effect and also prevent the guardrail 27 from directly acting on the hull 32 and damaging it.

[0034] Furthermore, when the safety pin 26 moves downward, it will also push the sealing plug 23 downward. After the sealing plug 23 moves downward, it can block the exhaust hole 34 below, and no longer block the air inlet pipe 24 and the air outlet pipe 25. At this time, the high-pressure air in the air storage tank 30 can be quickly input into the telescopic airbag 12 through the air inlet pipe 24, the air guide groove 22 and the air outlet pipe 25. The telescopic airbag 12 quickly stretches and bulges, and drives the rubber cover 13 to move upward, which can firmly drag the falling hull 32, further cushion the impact of the hull 32 falling, and also prevent the hull 32 from being damaged.

[0035] In summary, the present device can not only increase the fixing area and disperse the extrusion force generated during fixing on the surface of the support plate 8 with a larger area, but also effectively avoid the damaging effect of the fixing device on the surface of the hull 32, and prevent the hull from being concave and deformed during the fixing process; at the same time, the weight of the hull 32 is applied to the stable supporting mechanism 6, which can greatly enhance the safety performance when fixing the ship. At the same time, interception and protection components such as guardrails 27 and telescopic airbags 12 are provided, which can intercept, support and cushion the hull 32 in time when it falls, thereby protecting the hull 32 and avoiding injuries to nearby personnel.

[0036] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
