Description

Technical Field

[0001] This utility model relates to the technical field of sawing and milling equipment for deck lifting lugs, and specifically to an integrated sawing and milling machine for deck lifting lugs. Background Technology

[0002] Currently, temporary lifting lugs on shipyard decks need to be removed after their mission is completed. The existing removal method is basically to manually cut them with flames, and then manually grind the remaining parts with a polishing machine. The entire operation is very noisy and polluting, and there is an urgent need to improve the current situation. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an integrated sawing and milling machine for deck lugs that significantly reduces manpower and improves noise and pollution reduction.

[0004] Therefore, this utility model provides a deck lifting lug sawing and milling integrated machine, characterized in that it includes:

[0005] The frame includes a horizontal frame, support legs located below the horizontal frame, and a horizontal lead screw mounted longitudinally on the horizontal frame;

[0006] The liftable moving unit corresponds one-to-one with the number of support legs. Each liftable moving unit is configured to be lifted and mounted on one side of the corresponding support leg so as to switch between working and non-working states and includes a swivel wheel.

[0007] The sawing unit includes a saw mounting base, a metal band saw mounted on the bottom and top of the saw mounting base respectively, and a travel drive device 1, the travel drive device 1 including a nut that cooperates with a horizontal lead screw and can move along the horizontal lead screw;

[0008] The milling unit includes a milling mounting base, a two-dimensional milling device, and a second travel drive device, the second travel drive device including a second nut that cooperates with a horizontal lead screw and can move along the horizontal lead screw;

[0009] The support legs are equipped with energized electromagnets at their bottom. When the liftable and movable unit is in operation, the casters are on the deck and the energized electromagnets are not energized and are suspended in the air. When the liftable and movable unit is not in operation, the casters are suspended in the air and the energized electromagnets are energized and attached to the deck.

[0010] In this invention, the lifting and movable unit allows the entire machine to be pushed to a suitable position on the deck when the lifting lugs need to be removed; the energized electromagnet ensures that when the lifting and movable unit is not in operation, the electromagnet is energized and firmly attached to the deck; the sawing unit allows the metal band saw to move longitudinally along the extension direction of the horizontal lead screw to cut the lifting lugs; the milling unit cleanly mills away the remaining roots after sawing the deck lifting lugs; and the cooperation of the horizontal lead screw, the nut one of the sawing unit, and the nut two of the milling unit allows both the sawing and milling units to move longitudinally along the horizontal lead screw to complete sawing or milling.

[0011] Furthermore, the deck hoist sawing and milling integrated machine also includes a leveling and grounding unit, which corresponds one-to-one with the number of support legs. Each leveling and grounding unit is installed on the bottom of the corresponding support leg next to the corresponding liftable and movable unit. Each leveling and grounding unit includes the aforementioned energized electromagnet, a ball head mounting structure fixed on the energized electromagnet, and a ball head structure. The ball head structure is configured such that its bottom is rotatably installed inside the ball head mounting structure and its top is fixedly connected to the support leg.

[0012] The above structural design ensures that the frame remains level when the deck is not flat, by rotating the ball joint structure relative to the ball joint mounting structure.

[0013] Furthermore, the ball head mounting structure includes a ball head seat and a ball head cover. The ball head seat is fixed to an energized electromagnet and has a receiving cavity one. The ball head cover is fixedly connected to the ball head seat and has a receiving cavity two. The ball head structure includes a bottom ball head and a top threaded portion. The receiving cavity one and the receiving cavity two together form a ball socket that fits the bottom ball head, so that the bottom ball head can be rotatably installed in the ball socket. The top threaded portion is fixedly connected to the bottom of the support leg.

[0014] With the above structural design, the bottom ball head of the ball head structure is stably fitted into the ball socket of the ball head mounting structure and can rotate adaptively according to the flatness of the deck surface to stably support the frame fixedly connected to the ball head structure.

[0015] Furthermore, the leveling and grounding unit also includes a ball head shank threaded plate and a round nut for fixing the top threaded portion of the ball head structure to the bottom of the support leg. The ball head shank threaded plate is fixed to the bottom of the support leg by multiple bolts and has a central through hole. The top threaded portion is configured to extend upward through the central through hole and be fixed with the round nut.

[0016] The ball head structure is fixedly connected to the bottom of the support leg by means of the ball head shank threaded plate and round nut.

[0017] Furthermore, the ball head structure also has an intermediate flange between the bottom ball head and the top threaded part to support the ball head shank threaded plate; the round nut is located above the ball head shank threaded plate and its diameter is larger than the diameter of the central through hole.

[0018] The ball head shank threaded plate is limited by the intermediate flange, thus preventing it from sliding downwards.

[0019] Furthermore, the leveling and grounding unit also includes a ball-head bottom screw hole plate located below the ball head seat. The ball head seat and the ball-head bottom screw hole plate are fixed together to the energized electromagnet by multiple bolts. The ball-head bottom screw hole plate is provided with a wire outlet hole.

[0020] The ball-head bottom screw hole plate allows the power cable outlet hole for the energized electromagnet to be located on the ball-head bottom screw hole plate.

[0021] Furthermore, the liftable mobile unit also includes a fixed mounting base, a mobile mounting base, a jack, and a caster mounting frame. The fixed mounting base is fixedly connected to one side of the support leg and is equipped with a top piston baffle and a front slide rail. The mobile mounting base is equipped with a jack bearing seat and a rear slide groove that cooperates with the front slide rail. The jack is mounted on the jack bearing seat and has a handle and a piston that abuts against the top piston baffle. The caster mounting frame extends downward and outward from the mobile mounting base and is equipped with casters. The frame is also symmetrically equipped with lifting lugs for hoisting equipment on its top.

[0022] With the above-mentioned structural configuration of the liftable mobile unit, when the jack is operated by the handle, the piston of the jack extends outward or retracts inward. Since the piston is pressed against the top piston baffle of the fixed mounting base, the jack support can move up and down along the fixed mounting base, thereby realizing the conversion between the working state and the non-working state of the liftable mobile unit; with the setting of the lifting lugs on the frame, the entire deck lifting lug sawing and milling machine can be lifted to the position on the deck where the lifting lugs need to be cut when needed.

[0023] Furthermore, a pair of longitudinal slide rails parallel to the horizontal lead screw and located on both sides of the horizontal lead screw are provided on the horizontal frame. On the top of the saw mounting base, sliders that cooperate with the longitudinal slide rails are provided on both sides of the travel drive device. The travel drive device includes a turbine housing with a nut and a servo motor that drives the turbine housing via a coupling.

[0024] With the above structural setup, nut one, driven by servo motor one, moves the entire band saw mounting base and then the metal band saw along the horizontal lead screw, thereby realizing the sawing feed of the metal band saw.

[0025] Furthermore, a pair of longitudinal slide rails parallel to the horizontal lead screw and located on both sides of the horizontal lead screw are provided on the horizontal frame. Slider 2 that cooperate with the longitudinal slide rails are provided on both sides of the milling mounting base. The walking drive device 2 includes a turbine housing 2 with a nut 2 and a servo motor 2 that drives the turbine housing 2 via a coupling 2.

[0026] With the above structural setup, the second nut, driven by the second servo motor, moves the entire milling mounting base and the two-dimensional milling device along the horizontal lead screw, thereby achieving longitudinal feed milling.

[0027] Furthermore, the two-dimensional milling device includes a transverse movement unit, a Z-axis movement unit, and a milling unit. The transverse movement unit includes a transverse guide rail frame, a transverse slider seat, and a transverse servo motor. The transverse guide rail frame is mounted on the bottom front side of the milling mounting base and has a pair of transverse guide rails spaced apart in the height direction. A transverse lead screw is also installed on the transverse guide rail frame in the middle of the transverse guide rails. The transverse servo motor is mounted on one end of the transverse guide rail frame and drives the transverse lead screw. A pair of transverse sliders that cooperate with the transverse guide rails are provided on the rear side of the transverse slider seat. A transverse nut that cooperates with a transverse lead screw; a Z-axis moving unit including a Z-axis moving servo motor mounted on the top of the transverse sliding block seat, a pair of spaced Z-axis guide rails disposed on the front side of the transverse sliding block seat, a Z-axis lead screw disposed between the Z-axis guide rails and driven by the Z-axis moving servo motor, and a Z-axis moving seat with a pair of Z-axis sliders cooperating with the Z-axis guide rails and a Z-axis moving nut cooperating with the Z-axis lead screw disposed on the rear side; a milling unit including a milling cutter holder mounted on the front side of the Z-axis moving seat, a milling cutter mounted on the milling cutter holder and a power motor.

[0028] The above structural design enables the two-dimensional milling device to move laterally and vertically, thereby achieving two-dimensional feed milling.

The ball head structure 54 is configured such that its bottom is rotatably installed in the ball head mounting structure 52, while its top is fixedly connected to the support leg 12.

[0049] Specifically, in this embodiment, the ball head mounting structure 52 includes a ball head seat 521 and a ball head cover 523. The ball head seat 521 is fixed to the energized electromagnet 50 and has a first receiving cavity 522. The ball head cover 523 is fixedly connected to the ball head seat 521 and has a second receiving cavity (not shown in the figure). The ball head structure 54 includes a bottom ball head 540 and a top threaded portion 542. The first receiving cavity 522 and the second receiving cavity together form a ball socket 524 adapted to the bottom ball head 540 (see figure). Figure 5 Thus, the bottom ball head 540 is rotatably mounted in the ball socket 524.

[0050] like Figures 3 to 5 As shown, in this embodiment, the leveling and grounding unit 5 further includes a ball head shank threaded plate 56 and a round nut 58 for fixing the top threaded portion 542 of the ball head structure 54 to the bottom of the support leg 12.

Figure 7 As shown, the turbine housing 73 and the servo motor 77 are mounted on the saw mounting base 70 via the turbine housing mounting bracket 730 and the servo motor mounting bracket 770, respectively.

[0055] like Figures 8 to 12 As shown, in this embodiment, the milling unit 9 includes a milling mounting base 92, a two-dimensional milling device 90, and a second travel drive device 94. The second travel drive device 94 includes a second nut 974 that cooperates with the horizontal lead screw 14 and can move along the horizontal lead screw 14 (see...). Figure 10 );like Figure 8 and Figure 9 As shown, and refer to Figure 1 On the top of the milling mounting base 92, sliders 925 that cooperate with the longitudinal slide rails 15 on the horizontal frame 10 are provided on both sides of the travel drive device 94. The travel drive device 94 includes a turbine housing 97 and a servo motor 99. The turbine housing 97 has the aforementioned nut 974.

A transverse lead screw 913 is also installed on the transverse guide rail frame 910 between the transverse guide rails 911. The transverse servo motor 914 is mounted on one end of the transverse guide rail frame 910 and drives the transverse lead screw 913. A pair of transverse sliders 9121 (see 10) that cooperate with the transverse guide rails 911 and a transverse nut 9123 (see 10) that cooperate with the transverse lead screw 913 are provided on the rear side of the transverse slider seat 912.

[0057] It should be understood that the present invention may also include a controller, which is capable of controlling the leveling and grounding unit 5, the sawing unit 7 and the milling unit 9.

[0058] It should be noted that during use, the deck lug sawing and milling machine of this utility model is manually hoisted to the position on the deck where the lug needs to be cut. By manipulating the handle 350 of the jack 35, the downward reverse force of the piston baffle 310 on the top of the fixed mounting base 31 on the piston 352 of the jack 35 is used to push the movable mounting base 33 on which the jack 35 is mounted to move downward, so that the universal caster 30 contacts the deck. Then, the deck lug sawing and milling machine is pushed to the correct position. At this time, the pressure of the jack 35 is released, so that the universal caster 30 rises upward, and the energized electromagnet 50 of the leveling and grounding unit 5 is energized to attract onto the deck, thereby fixing the frame 1. The sawing unit 7 is turned on to cut the lug. After cutting, the lug is manually removed. The milling unit 9 is turned on until the remaining root of the lug is milled flat. This utility model uses the saw blade of the metal band saw (not shown) of the sawing unit 7 to saw the lug, and the remaining root is automatically milled flat by the milling machine. The operation requires virtually no human intervention, resulting in significant improvements in noise and pollution levels.
