Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a gantry cable pulling device. Background Technology

[0002] During shipbuilding, many large pieces of equipment need to be installed on the deck. Accurate installation and positioning are very important. Before installation, a cable-stayed system is usually used to center the equipment.

[0003] After the guy wire device is fixed on the deck, it is very difficult to adjust and position the traction wire in space. Existing guy wire devices that can adjust the position of the traction wire are large in size and complicated to install. They are inconvenient to install when positioning the guy wire on the deck, which seriously affects work efficiency. Moreover, repeated disassembly and assembly will damage the deck surface.

[0004] Therefore, there is an urgent need for a gantry crane guy wire device to solve the above problems. Summary of the Invention

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] like Figure 1As shown, the gantry cable pulling device of this embodiment includes two magnetic bases 1, two upright plates 2, a traction wire lateral adjustment assembly 3, and a traction wire locking assembly 4. The two magnetic bases 1 are spaced apart on the deck and are magnetically connected to the deck, which improves the installation efficiency of the gantry cable pulling device on the deck without damaging the deck surface. The two upright plates 2 are respectively fixed to the two magnetic bases 1. The two ends of the traction wire lateral adjustment assembly 3 are respectively connected to the two upright plates 2, and the traction wire lateral adjustment assembly 3 is used to adjust the movement of the traction wire along a first direction. The two ends of the traction wire locking assembly 4 are respectively connected to the two upright plates 2. The traction wire locking assembly 4 is located below the traction wire lateral adjustment assembly 3 and can move along a second direction to tighten the traction wire. The first direction is perpendicular to the second direction. The traction wire locking assembly 4 and the traction wire lateral adjustment assembly 3 cooperate with each other, and can adjust the position while tightening the traction wire, thus improving the working efficiency of the gantry cable pulling device.

[0038] Furthermore, the lateral adjustment assembly 3 includes a guide screw 31 and a guide pulley 32. The two ends of the guide screw 31 are respectively connected to two vertical plates 2. A traction wire is disposed on the guide pulley 32. The guide pulley 32 has a first internal threaded hole 3201 that mates with the guide screw 31. The guide screw 31 passes through the first internal threaded hole 3201 and is threadedly connected to the guide pulley 32, so that the guide pulley 32 can move along a first direction. Figure 1 , Figure 2 and Figure 3 As shown, the guide pulley 32 is sleeved on the guide screw 31 through the first internal threaded hole 3201. The engagement of the first internal threaded hole 3201 with the threaded surface of the guide screw enables the conversion between rotary and linear motion, allowing the traction wire to be adjusted along the first direction. In this embodiment, the position of the traction wire along the first direction can be adjusted simply by rotating the guide screw 31, making the operation simple and convenient. In other embodiments, other forms such as guide rails and sliders can also be used to adjust the position of the traction wire along the first direction; no specific limitation is made here.

[0039] Furthermore, both upright plates 2 are provided with first holes 201, and the two ends of the guide screw 31 are respectively inserted into the two first holes 201. The traction wire lateral adjustment assembly 3 also includes a first handle 33, one end of the guide screw 31 extends outward and is connected to the first handle 33, and the first handle 33 can drive the guide screw 31 to rotate. Rotating the first handle 33 to rotate the guide screw 31 makes operation more convenient.

[0040] Preferably, the traction wire lateral adjustment assembly 3 further includes a connecting plate 34, the extension end of the guide screw 31 has a square cross-section, and the connecting plate 34 has a square hole 3401 corresponding to the extension end of the guide screw 31. The first handle 33 and the guide screw 31 are connected by the connecting plate 34. Figure 7As shown, the connecting plate 34 has a square hole 3401 that mates with the guide screw 31. On the one hand, the square hole 3401 can improve the stability of the connection and assembly between the guide screw 31 and the connecting plate 34, and prevent relative sliding between the guide screw 31 and the connecting plate 34; on the other hand, the square hole 3401 can reduce the weight of the connecting plate 34, making installation and disassembly simple.

[0041] The gantry crane cable pulling device also includes a cover plate 5, which is located at the first hole 201 to block the other end of the guide screw 31. Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the studs at both ends of the guide screw 31 are respectively inserted into the first holes 201 on the two upright plates 2. One of the upright plates 2 has a cover plate 5 connected to its outer side. The cover plate 5 is bolted to the outer wall of the upright plate 2 to prevent the guide screw 31 from moving along the first direction.

[0042] In this embodiment, one end of the first handle 33 is provided with an external thread, and the connecting plate 34 is provided with a third internal thread hole 3402. The first handle 33 is threadedly connected to the connecting plate 34, so that the first handle 33 and the connecting plate 34 are firmly connected and easy to disassemble and assemble.

[0043] Continue as Figure 4 As shown, the outer wall of the guide pulley 32 has a groove 3202 along its circumference, and the traction wire is placed in the groove 3202. The traction wire is fixed in the groove 3202 to prevent it from sliding left and right on the guide pulley 32, which would affect the positioning accuracy of the wire. Preferably, rolling friction is formed between the traction wire and the guide pulley 32, thereby protecting the traction wire, improving its service life, and preventing it from breaking during wire pulling and affecting the quality of the wire pulling.

[0044] Furthermore, the traction wire locking assembly 4 includes a support plate 41 and a locking bolt 42. The two ends of the support plate 41 are respectively connected to two upright plates 2. The support plate 41 has a second internal threaded hole, through which the locking bolt 42 passes. The traction wire is connected to the locking bolt 42. Figure 8 As shown, the locking bolt 42 passes through the second internal threaded hole. By rotating the locking bolt 42, it moves along the second direction, thereby driving the traction wire to move along the second direction. In this embodiment, the traction wire locking assembly 4 is located below the traction wire lateral adjustment assembly 3. Therefore, the starting end of the traction wire is fixed on the locking bolt 42. While the locking bolt 42 is adjusting its position along the second direction, the tension of the traction wire can also be adjusted.

[0045] Preferably, the locking bolt 42 has a second hole 4201, through which the traction wire passes and is fixed to the locking bolt 42. In this embodiment, the starting end of the traction wire is passed through the second hole 4201 and the traction wire is knotted and fixed to the locking bolt 42, which is simple to operate.

[0046] To ensure accurate connection between the support plate 41 and the two upright plates 2, each upright plate 2 has a third hole 202, and both ends of the support plate 41 have fourth holes 4101 corresponding to the third holes 202. Connectors pass through the third holes 202 and the fourth holes 4101. In this embodiment, the connector is a pin, which is used for positioning to prevent deviations during installation.

[0047] Preferably, in order to ensure the stability of the connection between the support plate 41 and the two upright plates 2, a fifth hole 203 is provided on the upright plate 2, and a sixth hole is provided on the support plate 41 to cooperate with the fifth hole 203. Bolts pass through the fifth hole 203 and the sixth hole to connect the support plate 41 and the upright plate 2.

[0048] Furthermore, the magnetic base 1 includes a housing 11, a magnet 12 disposed within the housing 11, and an insulating material 13. The upright plate 2 is fixed to the housing 11. The insulating material 13 is disposed on multiple inner wall surfaces of the housing 11, except for the bottom inner wall surface of the housing 11, which is not provided with insulating material 13. The magnet 12 can rotate to allow the bottom of the magnetic base 1 to have an adsorption state and a separation state. In the adsorption state, the magnet 12 can be magnetically connected to the deck through the housing 11. In the separation state, an insulating material 13 is disposed between the housing 11 and the magnet 12, which can block the magnetic force of the magnet 12. Figure 9 As shown, the outer casing 11 is square, and the insulating material 13 is disposed inside the outer casing 11. The bottom surface of the outer casing 11 is not provided with the insulating material 13, allowing the magnetic force of the magnet 12 to pass through the outer casing 11, thereby causing the magnetic base 1 to adhere to the deck. Figure 9 As shown, the magnet 12 is in a separated state at this time. The magnet 12 is placed vertically, and the magnetic force of the magnet 12 is blocked by the insulating material 13. The magnetic base 1 is not connected to the deck. When the magnet 12 is rotated 90° counterclockwise, the magnet 12 is placed horizontally. The bottom surface of the magnetic base 1 is not covered by the insulating material 13. The magnet 12 forms a magnetic field through the outer shell 11 and is attracted to the deck, so that the magnetic base 1 is connected to the deck.

[0049] In this embodiment, the upright plate 2 is welded to the outer wall of the outer casing 11, making the connection between the upright plate 2 and the outer casing 11 more stable. In other embodiments, other connection methods may also be used, such as threaded connections, etc., which are not specifically limited here.

[0050] Preferably, the outer casing 11 is further provided with a second handle 14, which is connected to the magnet 12 and drives the magnet 12 to rotate. By rotating the second handle 14, the magnet 12 is driven to rotate, thereby controlling the attraction force of the magnetic base 1, making operation simple and convenient. At the same time, the magnetic base 1 will not damage the deck surface when connected to the deck, and disassembly is simple.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
