Description

Technical Field

[0001] The present invention relates to the technical field of ship block construction, and specifically to a walking platform for ship block construction projects. Background Art

[0002] The block construction method is a general term for the technologies, methods, and skills of building boats and ships. When implementing the block construction method, it is necessary to draw the drawings of the hull, decompose the ship into several blocks or sub-assemblies, determine the quantity and volume of the blocks to be constructed, first construct the blocks separately, then use gantry cranes to assemble the ship together, and finally obtain the required ship through welding. The application of the block construction method not only improves the construction efficiency but also reduces the construction cost; as a heavy-duty crane, the gantry crane mainly consists of four major parts: a metal structure, a running mechanism, a hoisting mechanism, and electrical equipment. In a shipyard, the rail-mounted gantry crane is the walking mechanism for ship block construction. The gantry crane rails are installed on concrete track beams. Due to the huge weight of the ship, the concrete track beams are under high-intensity pressure for a long time, and it is inevitable that the rails will sag. Once the rails sag, the track wheels will be unevenly stressed, prone to safety hazards such as derailment and excessive inclination of the gantry crane, and it is also very difficult for the staff to detect the deformation of the rails; in addition, the gantry crane is huge in size, and the steel ropes used for lifting on the hoisting mechanism cannot be regularly maintained, resulting in increased wear of the steel ropes, shortened service life, and high usage costs. In order to improve the safety of ship movement, a special walking platform for ship block construction is proposed. Summary of the Invention

[0008] Optionally, the transmission ratio of the driving gear to the driven gear is greater than 2.

[0009] Optionally, the purpose is to apply lubricating oil to the wire rope to reduce the wear of the wire rope.

[0014] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows:

[0015] 1. When the first track drops in the present invention, affected by the first rotating shaft, the two track wheels are always in contact with the first track. The two track wheels are evenly stressed, reducing the pressure on the track wheels when the first track deforms. The support beam tilts as the first track drops. The transmission between the spur gear and the toothless gear can make the notch rotate. The inclined surface of the notch presses the travel switch, and the buzzer is powered on to sound an alarm. The first valve core is rotated by the reduction motor to make the water tank carry the cooling water to move. The cooling water precisely falls on the surface of the track wheel through the dropper. The cooling water absorbs heat and vaporizes to cool the track wheel. Therefore, when the track drops, the track wheels are evenly stressed, avoiding potential safety hazards such as derailment and excessive inclination of the gantry crane, and being able to monitor the deformation of the first track, facilitating the staff to take maintenance measures in a timely manner.

[0016] 2. The present invention drives the turntable to rotate through a biaxial motor. As the guide groove rotates, the curved surface of the guide groove can squeeze the driving rod inward. At the same time, the conduit moves inward, and the second valve core rotates on the second valve body, enabling the diversion groove to communicate with the flow channel. The brush contacts the steel wire rope on the electric hoist. Through the flow channel, the diversion groove, and the conduit for drainage, the lubricating oil reaches the surface of the brush, allowing the brush to apply lubricating oil to the steel wire rope. It has the function of regular maintenance of the steel wire rope, reducing the wear of the steel wire rope, extending its service life, and reducing the shipbuilding cost.

[0031] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.

[0032] Embodiment, please refer to Figures 1 - 10 In the embodiment of the present invention, a walking platform for ship sectional construction projects includes two first tracks 1, two brackets 2, a main beam 3, and two second tracks 4. The two first tracks 1 are preset on the top of the concrete track beam. The tops of the two brackets 2 are respectively fixedly connected to the front and rear ends of the lower surface of the main beam 3. The brackets 2 play a supporting role for the main beam. The two second tracks 4 are respectively fixedly connected to the left and right ends of the bottom of the inner cavity of the main beam 3. Anti-falling mechanisms 5 are fixedly connected to the left and right ends of the lower surface of the brackets 2. By moving on the first track 1 through the anti-falling mechanisms 5, the main beam 3 can be moved. Cranes 6 are slidably connected to the front and rear ends of the top of the second track 4. An electric hoist 7 is fixedly connected to the lower surface of the crane 6. A lifting tool 8 is installed at the bottom of the steel wire rope of the electric hoist 7. By means of the second track 4, the crane 6 can drive the electric hoist 7 to move back and forth. The electric hoist 7 winds or releases the steel wire rope, enabling the lifting tool 8 to rise or fall. The lifting tool 8 lifts and moves ship parts. A lubricating mechanism 9 is fixedly connected to the lower surface of the electric hoist 7 to lubricate the steel wire rope on the electric hoist 7.

[0033] Furthermore, as Figure 3As shown in the figure, 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 surface of the first support seat 51. The buzzer 52 emits an alarm sound to remind the staff that the first track 1 has fallen. At the bottom of the inner cavity of the first support seat 51, a rotatable first rotating shaft 53 is installed. At the front and rear ends of the outer wall of the first rotating shaft 53, a spur gear 54 and a support beam 55 are respectively installed. At the top of the inner cavity of the first support seat 51, a toothed gear 56 capable of rotating is installed through a pin shaft, and the toothed gear 56 is meshed with the spur gear 54. A notch 57 is formed at the top of the outer wall of the toothed gear 56. The transmission ratio of the spur gear 54 to the toothed gear 56 is less than 1. When the spur gear 54 and the toothed gear 56 are in transmission, the swing angle of the notch 57 on the toothed gear 56 is amplified. At the top of the inner cavity of the first support seat 51, a travel switch 58 electrically connected to the buzzer 52 is installed, 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 toothed gear 56 rotates, the inclined surface of the notch 57 can make the travel switch 58 move to the side wall of the toothed gear 56 and trigger the travel switch 58. Both the left and right ends of the support beam 55 are fixedly connected with traveling components 59. By rolling the traveling components 59 on the first track 1, the transverse movement of the main beam 3 is realized.

[0034] Further, as Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the walking assembly 59 includes a second support base 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 base 591. A first valve body 593 is installed at the bottom of the water tank 592. A rotatable first valve core 594 is inserted into the inner cavity of the first valve body 593. Water grooves 595 are equidistantly arranged along the circumferential direction on the outer wall of the first valve core 594. When the first valve core 594 drives the water grooves 595 to rotate, the water grooves 595 can carry the cooling water to move, causing the cooling water to drip intermittently. A dropper 596 corresponding to the position of the water grooves 595 is installed at the bottom of the first valve body 593. A rotatable second rotating shaft 597 is installed at the bottom of the inner cavity of the second support base 591. A driven gear 598 and a track wheel 599 are respectively installed at the front and rear ends of the outer wall of the second rotating shaft 597. The track wheel 599 can roll on the first track 1. The cooling water is accurately dropped on the surface of the track wheel 599 through the dropper 596. The high temperature generated when the track wheel 599 rotates vaporizes the cooling water, and the cooling water absorbs the heat on the surface of the track wheel 599 to cool the track wheel 599. A dust-proof cover 5910 is fixedly connected to the front of the second support base 591. A reduction motor 5911 connected to the first valve core 594 is installed at the top of the front of the dust-proof cover 5910. A driving gear 5912 meshed with the driven gear 598 is installed at 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 the track wheel 599 is a speed reduction, and the load of the reduction motor 5911 decreases, which has a protective meaning for the reduction motor 5911.

[0035] Further, as Figure 8 and Figure 10 shown, the lubrication mechanism 9 includes a lubricating oil tank 91 fixedly connected to the lower surface of the electric hoist 7. A double-shaft motor 92 is installed at the bottom of the lubricating oil tank 91. Turntables 93 are installed at both ends of the double-shaft motor 92. Two guide grooves 94 opposite in position are opened on the outer wall of the turntable 93. Adding components 95 are 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 horizontally 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. The guide grooves 94 are arc-shaped and inclinedly distributed on the outer wall of the turntable 93. When the double-shaft 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.

[0036] Further, as Figure 9As shown in the figure, the adding component 95 includes a second valve body 951 fixedly connected to the bottom of the lubricating oil tank 91. Flow channels 952 are provided at both the front and rear ends of the upper surface of the second valve body 951. Second valve cores 953 that can rotate are inserted into both the front and rear sides of the bottom of the second valve body 951. A diversion groove 954 is provided inside the second valve core 953. The two diversion grooves 954 are symmetric about the center point of the second valve body 951 in the front and rear directions. When the two second valve cores 953 rotate in opposite directions, the diversion groove 954 can be communicated with the flow channel 952 to introduce lubricating oil. A conduit 955 is installed on the outer wall of the second valve core 953. 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 end of the conduit 955. The conduit 955 is inclined 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. Through the connection of the driving rod 96, the turntable 93 and the conduit 955 can be interlocked. When the two conduits 955 move inward, the brush 956 can contact the steel wire rope on the electric hoist 7. Through holes are provided on the surface of the brush 956, and the lubricating oil is smeared on the surface of the steel wire rope to achieve regular maintenance of the steel wire rope.

[0037] Working principle:

[0038] Step 1: The electric hoist 7 is used to tow the lifting appliance 8 to rise and fall, so that the lifting appliance 8 lifts the ship fittings. Driven by the reduction motor 5911, the driving gear 5912 rotates. The driving gear 5912 is in transmission with the driven gear 598, so that the track wheel 599 can move left and right on the first track 1 to carry out the handling of the ship fittings.

[0039] Step 2: When the track wheel 599 rolls, it generates heat due to friction with the first track 1. 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 to cool down the track wheel 599, preventing the track wheel 599 from rising in temperature and decreasing in hardness, and protecting the track wheel 599.

[0040] Step 3: Under the action of the gravity of the ship fittings, the concrete track beam is under heavy load for a long time, and the strength of the concrete track beam will also decrease. The first track 1 is prone to sag. Once the first track 1 sags, the track wheel 599 will drop. The forces on the two track wheels 599 on the support beam 55 are still close to being balanced. The support beam 55 rotates slightly and will not cause the support 2 to tilt severely, preventing safety hazards such as derailment of the track wheel. When the support beam 55 tilts, the spur gear 54 drives the toothless gear 56 to rotate. The inclined surface of the notch 57 squeezes the travel switch 58, and the travel switch 58 is triggered, causing the buzzer 52 to sound an alarm, reminding the staff that the first track 1 has sagged and enabling timely discovery of safety hazards.

[0041] Step 4, when regular maintenance of the steel wire rope on the electric hoist 7 is required, the rotary table 93 is driven to rotate by the double-shaft motor 92, so that the curved surface of the guide groove 94 presses the driving rod 96 inward, prompting the conduit 955 to swing inward. At the same time, the second valve core 953 rotates until the diversion groove 954 communicates with the flow channel 952, and the brush 956 contacts the steel wire rope. Under the guiding action of the flow channel 952 and the diversion groove 954, the lubricating oil in the lubricating oil tank 91 enters the brush 956 through the conduit 955. The through holes on the brush 956 allow the lubricating oil to flow to the bristles, applying the lubricating oil to the steel wire rope, reducing the wear degree of the steel wire rope, and extending the service life of the steel wire rope.

[0042] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
