[0029] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0030] Please refer to the attached document. Figure 1-4This application provides a wire saw type lifting lug cutting device, including a base, a wire saw cutting device, and a first driving device. The base includes a first mounting base 110 and an adsorption device disposed on the first mounting base 110. The adsorption device can generate an adsorption force and adsorb the device support base through the adsorption force, thereby fixing the base to the device support base. Here, the device support base refers to the structure used to place and support the wire saw type lifting lug cutting device, such as, but not limited to, the plate on which the lifting lug to be cut is located. The above-mentioned adsorption device can fix the base to the plate during the cutting device operation to ensure the stable operation of the cutting device. The wire saw cutting device includes a second mounting base 210 and a wire saw assembly disposed on the second mounting base 210. The wire saw assembly includes a rope wheel assembly and a saw rope 240 fitted on the rope wheel assembly. The saw rope 240 rotates rapidly under the drive of the rope wheel assembly to cut the lifting lug. The second mounting base 210 is movably disposed on the first mounting base 110 in a set direction. The first driving device is disposed on the first mounting base 110 and the second mounting base 210. The first driving device is used to drive the wire saw cutting device to move, so as to control the forward and backward movement of the wire saw cutting device.

[0031] The operation process of the wire saw type lifting lug cutting equipment provided in this embodiment is as follows: the wire saw type lifting lug cutting equipment is transported to the working position, then the base is fixed to the plate using an adsorption device, and then the wire saw assembly is started to automatically cut the lifting lug until the lifting lug is cut off. During the cutting, the first drive device drives the wire saw cutting device to move toward the lifting lug.

[0032] The wire saw-type lifting lug cutting equipment provided in this embodiment can achieve automated mechanical cutting and removal of lifting lugs using a wire saw method, eliminating the need for manual hand-held flame cutting. This not only reduces labor costs and eliminates the safety hazards of manual lug cutting, but also avoids damage to the paint and structure of the board surface. Furthermore, the wire saw cutting device produces a smooth cut, increasing the number of times the lifting lug can be reused and extending its service life, while minimizing lug residue. The high cutting precision of the equipment also prevents inconsistent cutting quality due to human fatigue, thereby reducing the workload and cost of subsequent board grinding and repair. In addition, compared to flame cutting, the cutting equipment of this application consumes less energy and is more environmentally friendly.

[0033] The adsorption device can be, but is not limited to, an electromagnet 120, a vacuum suction cup, etc. Since the sheet metal used in shipbuilding is typically steel, the preferred adsorption device is an electromagnet 120, which not only has a long service life and high structural strength, but also has lower requirements for the flatness of the sheet metal surface. The setting direction can be the length direction of the second mounting base 210.

[0034] In some embodiments of this application, the adsorption device is disposed on the side of the first mounting base 110 away from the second mounting base 210, so that the adsorption device can suspend and support the first mounting base 110 on the plate, thereby forming an installation space on the side of the first mounting base 110 away from the second mounting base 210. The wire saw assembly is disposed on the side of the second mounting base 210 close to the first mounting base 110, and the wire saw assembly is located in the installation space. This not only allows the saw wire 240 to be closer to the plate, resulting in less downward pressure on the saw wire 240 by the pressure roller 270 and extending the service life of the saw wire 240, but also contributes to the miniaturization of the cutting equipment, making the cutting equipment more lightweight and flexible to use. Furthermore, during operation, the adsorption device can directly contact the plate, which helps to increase the adsorption and fixation effect between the adsorption device and the plate, improving the operational stability of the cutting equipment.

[0035] In some embodiments of this application, the second mounting base 210 extends beyond the first mounting base 110 at one end along a predetermined direction, and the extended end of the second mounting base 210 is provided with a clearance notch 211 that extends along the predetermined direction. A portion of the saw rope 240 is located on the side of the extended end of the second mounting base 210 closer to the first mounting base 110. During cutting operations, the clearance notch 211 allows the second mounting base 210 to avoid the lifting lug when moving near it, thus allowing the dimensions of the second mounting base 210 along the predetermined direction to be smaller and its height to be lower, contributing to the miniaturization of the cutting equipment.

[0036] In some embodiments of this application, the sheave assembly includes a driving sheave 220 and at least two driven sheaves 230. The two driven sheaves 230 are disposed at the extended end of the second mounting base 210. The first mounting base 110 is a frame structure and has a mounting cavity. The driving sheave 220 is located on the side of the mounting cavity away from the second mounting base 210. This arrangement allows for a more compact structure of the wire saw cutting device. The two driven sheaves 230 can be spaced apart parallel to the width direction of the second mounting base 210.

[0037] Preferably, the first mounting base 110 is a rectangular frame structure. The first mounting base 110 includes two first side frames 111 parallel to a predetermined direction and two second side frames 112 respectively connecting the same side ends of the two first side frames 111. A mounting cavity is formed between the two first side frames 111 and the two second side frames 112. Electromagnets 120 are provided at the bottom of each of the two first side frames 111 and the two second side frames 112. Guide rail assemblies are installed between the two first side frames 111 and the second mounting base 210, and the second mounting base 210 is slidably mounted on the first mounting base 110 via the guide rail assemblies. The first driving device includes a first driving motor 310, a transmission gear 320, and a transmission rack 330. The first driving motor 310 is disposed on the top of the second mounting base 210. The transmission rack 330 extends along a predetermined direction and is disposed inside one of the first side frames 111. The transmission shaft of the first driving motor 310 is in transmission engagement with the transmission gear 320, and the transmission gear 320 meshes with the transmission rack 330. The top of the second mounting base 210 is also provided with a second drive motor 260. The output shaft of the second drive motor 260 is driven by the drive pulley 220 to rotate. In order to improve the output torque, a reducer can be configured between the drive shaft of the first drive motor 310 and the drive gear 320, and between the output shaft of the second drive motor 260 and the drive pulley 220.

[0038] It should be understood that the first driving device is not limited to the above, and may also be a lead screw mechanism, a hydraulic cylinder or an electric push rod, etc.

[0039] In some embodiments of this application, the wire saw cutting device further includes at least two pressure rollers 270. The two pressure rollers 270 are spaced apart along the width direction of the second mounting base 210 at the extended end of the second mounting base 210, and the two pressure rollers 270 are located on the side of the saw rope 240 close to the second mounting base 210. The pressure rollers 270 are used to press the saw rope 240, which on the one hand makes the saw rope 240 fit the board more closely and reduces the residual amount of the lifting lug, and on the other hand keeps the part of the saw rope 240 in contact with the lifting lug stable, thereby improving the reliability of the saw rope 240 operation.

[0040] The pressure roller 270 is movable in a direction close to or away from the saw rope 240, allowing adjustment of the distance between the saw rope 240 and the sheet metal, as well as the pressure of the pressure roller 270 on the saw rope 240, thus improving the practicality of the equipment. Preferably, the extended end of the second mounting base 210 is provided with a height adjuster 280, and the pressure roller 270 is disposed on the height adjuster 280. The height adjuster 280 is a common structure in the art, and will not be described in detail here.

[0041] In some embodiments of this application, a spraying device is also included. The spraying device is disposed on the second mounting base 210. The spraying device includes a spray head, wherein the spray head is disposed toward the saw rope 240 to spray coolant onto the saw rope 240 to reduce the temperature of the saw rope 240 and extend the service life of the saw rope 240.

[0042] The spraying device also includes a storage tank and a booster pump mounted on the second mounting base 210. The outlet of the storage tank is connected to the inlet of the booster pump via a conduit, and the outlet of the booster pump is connected to the inlet of the spray head via a conduit.

[0043] Optionally, there are at least two spray heads, and the two spray heads are arranged between the two pressure rollers 270 to spray coolant onto the portion of the saw rope 240 located between the two pressure rollers 270.

[0044] In some embodiments of this application, a walking device is also included, which is disposed on the first mounting base 110 or the second mounting base 210. The walking device is movably configured to switch between a folded position and a working position. In the working position, the walking device is located below the base and suspends to support the base, allowing the cutting equipment to move freely. In the folded position, the walking device is higher than the lowest point of the base, causing the base to lose support and touch the ground. By configuring the aforementioned walking device, the cutting equipment can be moved freely using the walking device under the push of the operator, improving the flexibility of the cutting equipment. Furthermore, when moving to the working position, the walking device can be folded and stored, allowing the base to touch the ground at the working position.

[0045] In some embodiments of this application, the walking device includes two walking structures 410 and a drive rod 420. The two walking structures 410 are respectively disposed on both sides of the first mounting base 110 or the second mounting base 210 where the walking device is located, along the width direction. Each walking structure 410 includes two connecting plates 411, two rollers 413, and a connecting rod 412. The two connecting plates 411 are spaced apart along a predetermined direction and are rotatably connected to the first mounting base 110 or the second mounting base 210 where the walking device is located. The two rollers 413 are respectively mounted on the two connecting plates 411. The connecting rod 412 is connected to the two connecting plates 411. The drive rod 420 is located on one side of the two walking structures 410 along the predetermined direction and is connected to the two adjacent connecting plates 411. The above-mentioned walking structures 410 constitute a linkage mechanism, and the two walking mechanisms can move synchronously under the drive of the drive rod 420 to change the position of the walking device.

[0046] When the walking device switches from the folded position to the working position, the user can press down the drive rod 420 to drive the two walking mechanisms to rotate synchronously toward the avoidance gap 211, and lift the base and the wire saw cutting device together during the rotation. When the walking device switches from the working position to the folded position, the user can pull up the drive rod 420 to drive the walking mechanism to rotate away from the avoidance gap 211, and lower the base and the wire saw cutting device together during the rotation.

[0047] Preferably, the second mounting base 210 has two mounting plates 250 on both sides along the width direction. The two mounting plates 250 on one side of the mounting base are spaced apart along the direction of the second mounting base 210. The connecting plate 411 in the walking mechanism on the same side is rotatably connected to the two mounting plates 250. The mounting plate 250 is provided with a hook section 251, and the first frame 111 adjacent to it is hung in the hook section 251. The hook section 251 can form a limiting constraint on the first frame 111 along the width direction of the base. A positioning assembly is provided between a pair of connected mounting plates 250 and connecting plates 411. The positioning assembly includes a positioning hole on the mounting plate 250 and a pluggable positioning pin on the connecting plate 411. In the working position, the positioning pin is inserted into the positioning hole to fix the walking device in the working position.
