[0032] Further, such as Figure 3As shown, the anti-falling mechanism 5 includes a first support seat 51 fixedly connected to the lower surface of the bracket 2, a buzzer 52 is installed on the front of the first support seat 51, and the buzzer 52 sounds an alarm to remind the staff that the first track 1 has fallen, a rotatable first shaft 53 is installed at the bottom of the inner cavity of the first support seat 51, and a spur gear 54 and a support beam 55 are installed at the front and rear ends of the outer wall of the first shaft 53 respectively, and a rotatable missing tooth gear 56 is installed at the top of the inner cavity of the first support seat 51 through a pin shaft, and the missing tooth gear 56 is meshed with the spur gear 54, and a notch 57 is provided on the top of the outer wall of the missing tooth gear 56, and the spur gear 54 and the missing tooth gear The transmission ratio of 56 is less than 1. When the spur gear 54 and the toothless gear 56 are transmitting, the swing angle of the notch 57 on the toothless gear 56 is magnified. A travel switch 58 electrically connected to the buzzer 52 is installed on the top of the inner cavity of the first support seat 51, and the travel switch 58 is inserted into the inner cavity of the notch 57. Both ends of the inner cavity of the notch 57 are inclined surfaces. When the toothless gear 56 rotates, the inclined surface of the notch 57 can allow the travel switch 58 to move to the side wall of the toothless gear 56 and trigger the travel switch 58. The left and right ends of the support beam 55 are fixedly connected with walking components 59, and the walking components 59 roll on the first track 1 to realize the lateral movement of the main beam 3.

[0033] Further, such as Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the walking assembly 59 includes a second support seat 591 fixedly connected to the end of the support beam 55, a water tank 592 for storing cooling water is installed on the top of the second support seat 591, a first valve body 593 is installed at the bottom of the water tank 592, a first valve core 594 that can rotate is inserted into the inner cavity of the first valve body 593, and the outer wall of the first valve core 594 is provided with water grooves 595 at equal intervals along the circumferential direction. When the first valve core 594 drives the water groove 595 to rotate, the water groove 595 can move with the cooling water, so that the cooling water can drip intermittently, a dropper 596 corresponding to the position of the water groove 595 is installed at the bottom of the first valve body 593, a second rotatable shaft 597 is installed at the bottom of the inner cavity of the second support seat 591, and a driven gear 598 and a driven gear 599 are installed at the front and rear ends of the outer wall of the second rotating shaft 597 respectively. Track wheel 599, track wheel 599 can roll on the first track 1, and cooling water is accurately dripped on the surface of track wheel 599 through dropper 596. The high temperature generated when track wheel 599 rotates causes cooling water to vaporize, and cooling water absorbs heat from the surface of track wheel 599 to cool down track wheel 599. A dust cover 5910 is fixedly connected to the front of the second support seat 591, and a reduction motor 5911 connected to the first valve core 594 is installed on the top of the front of the dust cover 5910. A driving gear 5912 meshing with the driven gear 598 is installed on the output end of the reduction motor 5911. The transmission ratio of the driving gear 5912 to the driven gear 598 is greater than 2. The rotation of track wheel 599 is a deceleration, and the load of the reduction motor 5911 decreases, which has a protective significance for the reduction motor 5911.

[0034] Further, such as Figure 8 and Fig.10 As shown, the lubrication mechanism 9 includes a lubricating oil tank 91 fixedly connected to the lower surface of the electric hoist 7, a dual-axis motor 92 is installed at the bottom of the lubricating oil tank 91, a turntable 93 is installed at both ends of the dual-axis motor 92, and two guide grooves 94 in opposite positions are opened on the outer wall of the turntable 93, and an adding component 95 is fixedly connected to the left and right ends of the bottom of the lubricating oil tank 91, one end of a driving rod 96 is laterally inserted into the inner cavity of the guide groove 94, and the other end of the driving rod 96 is connected to the outer wall of the adding component 95, and the guide groove 94 is distributed in an arc shape and tilted on the outer wall of the turntable 93. When the dual-axis motor 92 drives the turntable 93 to rotate clockwise or counterclockwise, the inclined surface of the guide groove 94 can squeeze the driving rod 96 inward or outward.

[0035] Further, such as Fig. 9As shown, the adding component 95 includes a second valve body 951 fixedly connected to the bottom of the lubricating oil tank 91, and flow channels 952 are provided at both ends of the upper surface of the second valve body 951. A rotatable second valve core 953 is inserted at both the front and rear sides of the bottom of the second valve body 951. A guide groove 954 is provided inside the second valve core 953. The two guide grooves 954 are symmetrical with respect to the center point of the second valve body 951. When the two second valve cores 953 rotate in opposite directions, the guide grooves 954 can be connected to the flow channel 952 to introduce lubricating oil. The outer wall of the second valve core 953 is provided with a A conduit 955 is provided, the outer wall of the conduit 955 is connected to the end of the driving rod 96, a brush 956 is installed at the bottom of the conduit 955, and the conduit 955 is tiltedly arranged on the outer wall of the second valve core 953, so that the brush 956 and the steel wire rope on the electric hoist 7 are in the same plane, and the turntable 93 and the conduit 955 can be linked by connecting with the driving rod 96. When the two conduits 955 move inward, the brush 956 can contact with the steel wire rope on the electric hoist 7. A through hole is arranged on the surface of the brush 956, and lubricating oil is applied to the surface of the steel wire rope to achieve regular maintenance of the steel wire rope.

[0036] Working principle: Step 1: The lifting device 8 is pulled up and down by the electric hoist 7, so that the lifting device 8 lifts the ship accessories, and the driving gear 5912 is driven by the reduction motor 5911 to rotate. The driving gear 5912 and the driven gear 598 can drive the track wheel 599 to move left and right on the first track 1, so as to transport the ship accessories; Step 2: When the track wheel 599 rolls, it rubs against the first track 1 and generates heat. As the reduction motor 5911 drives the first valve core 594 to rotate, the water tank 595 carries the cooling water flowing out of the water tank 592 and moves along the inner wall of the first valve body 593. The dropper 596 drops the cooling water on the surface of the track wheel 599. The cooling water absorbs heat and vaporizes, thereby cooling the track wheel 599, preventing the track wheel 599 from heating up and decreasing its hardness, thereby protecting the track wheel 599. Step 3: Due to the gravity of the ship accessories, the concrete track beam is under a large load for a long time, and the strength of the concrete track beam will also decrease. The first track 1 is prone to falling. Once the first track 1 falls, the track wheel 599 will fall, and the forces on the two track wheels 599 on the support beam 55 are still close to balanced. The support beam 55 rotates slightly, and does not cause the bracket 2 to tilt seriously, preventing the track wheel from derailing and other safety hazards. When the support beam 55 tilts, the spur gear 54 drives the toothless gear 56 to rotate, and the notch 57 is pressed by the inclined surface of the travel switch 58, which triggers the travel switch 58, causing the buzzer 52 to sound an alarm, reminding the staff that the first track 1 has fallen, so that safety hazards can be discovered in time; Step 4, when the wire rope on the electric hoist 7 needs to be maintained regularly, the turntable 93 is driven to rotate by the dual-axis motor 92, so that the curved surface of the guide groove 94 squeezes the driving rod 96 inward, causing the guide tube 955 to swing inward, and at the same time the second valve core 953 rotates until the guide groove 954 is connected with the flow channel 952, and the brush 956 contacts the wire rope. The lubricating oil in the lubricating oil tank 91 flows through the flow channel 952 and the guide groove 954, and the lubricating oil enters the brush 956 through the guide tube 955. The through hole on the brush 956 allows the lubricating oil to flow to the bristles, and the lubricating oil is applied to the wire rope, thereby reducing the degree of wear of the wire rope and extending the service life of the wire rope.

[0037] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
