DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] Although the present utility model can be easily embodied in different forms of embodiments, only some specific embodiments are shown in the drawings and will be described in detail in this specification. At the same time, it can be understood that this specification should be regarded as a demonstration of the principle of the present utility model, rather than aiming to limit the present utility model to what is described herein.

[0037] Accordingly, a feature pointed out in this specification is used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the illustrated feature. In addition, it should be noted that this specification describes many features. Although some features may be combined to show possible system designs, these features can also be used in other combinations not explicitly described. Accordingly, unless otherwise stated, the illustrated combinations are not intended to be limiting.

[0038] In the embodiments shown in the drawings, the indication of directions (such as up, down, left, right, front, and back) is used to explain that the structures and movements of various elements of the present invention are not absolute but relative. When these elements are in the positions shown in the drawings, these explanations are appropriate. If the descriptions of the positions of these elements change, then the indication of these directions also changes accordingly.

[0039] The present invention provides a portable cutting device, which includes a connecting mechanism and a cutting mechanism, and the two are detachably connected, so that they can be carried separately and then assembled at the place to be cut, making it convenient to carry.

[0040] This portable cutting device is particularly suitable for cutting the scaffolding eye plates on structures such as ships and jacket platforms. The following takes cutting the scaffolding eye plates on a ship as an example for introduction.

[0041] Figure 1 The structural schematic diagram of the portable cutting device is shown, Figure 2 and Figure 3 both show the front view schematic diagram of the portable cutting device, the difference lies in the position of the cutting mechanism. Combining Figures 1-3 , the connecting mechanism includes a connecting piece and a supporting piece arranged on the connecting piece. The connecting piece is used for detachably connecting with the structure around the plate to be cut. The connecting piece has an opening exposing at least part of the plate to be cut.

[0042] The connecting piece includes two connecting rods 111 arranged in parallel at intervals, connecting seats 112 arranged at both ends of each connecting rod 111, and magnetic suction seats 113 arranged on the connecting seats 112 relative to the ends of the connecting rods 111. The magnetic suction seats 113 are connected with the structure around the plate to be cut through magnetic suction.

[0043] That is, the magnetic suction seat 113 is connected to the connecting rod 111 through the connecting seat 112. Along the length direction of the connecting rod 111, they are in turn the magnetic suction seat 113, the connecting seat 112, the connecting rod 111, the connecting seat 112, and the magnetic suction seat 113. One connecting rod 111, two connecting seats 112, and two magnetic suction seats 113 form a connecting structure. Therefore, the connecting piece includes two independent connecting structures, making it convenient to carry and transport the connecting piece.

[0044] The magnetic seat 113 includes a magnetic member 1131 and a knob switch 1132. The knob switch 1132 can control the magnitude of the magnetic force of the magnetic member 1131. Exemplarily, when the knob switch 1132 is rotated to the first position, the magnetic member 1131 has a large magnetic force, so that the magnetic seat 113 can be firmly adsorbed on the structure around the board to be cut, such as adsorbed on a ship. When the knob switch 1132 is rotated to the second position, the magnetic force of the magnetic member 1131 is reduced or even disappears. At this time, there is no magnetic attraction between the magnetic seat 113 and the ship, and the connection between the magnetic seat 113 and the ship is released.

[0045] In this embodiment, the magnetic seat 113 is block-shaped.

[0046] The connecting seat 112 is block-shaped. The cross section of the connecting rod 111 is circular.

[0047] The support member is arranged on the connecting rod 111 to support the cutting mechanism. The plane where the support member is located is perpendicular to the plane where the connecting member is located. That is, when the connecting member is arranged in the horizontal direction, the support member extends in the vertical direction.

[0048] Specifically, the support member includes two support rods 114. That is, the two support rods 114 extend in a direction perpendicular to the plane where the connecting member is located.

[0049] Preferably, the support member can move along the length direction of the connecting member, specifically, the two support rods 114 are movably connected to the two connecting rods 111. The cutting direction of the cutting member is perpendicular to the length direction of the connecting member.

[0050] At least one of the two connecting rods 111 is an active rod, which is rotatably connected to the connecting seat 112. The outer periphery of the active rod is provided with an external thread, which spirally extends along the length direction of the connecting rod 111. The support rod 114 corresponding to the active rod is threadedly connected to the active rod.

[0051] In this embodiment, a connecting block 115 is fixed to the end of the supporting rod 114 , and the connecting block 115 has openings at both ends and a hollow interior. The connecting block 115 is sleeved on the outer circumference of the connecting rod 111 .

[0052] The portable cutting device 1 includes at least one driving member 116 , and the driving member 116 drives the active rod to rotate, thereby driving the supporting rod 114 corresponding to the active rod to move along the length direction of the active rod.

[0053] In this embodiment, one of the two connecting rods 111 is provided with an external thread, and the other connecting rod 111 is not provided with an external thread, that is, only one of the connecting rods 111 is an active rod. In this case, the number of the driving member 116 is one, which is arranged on the connecting seat 112 corresponding to the active rod and connected to the active rod.

[0054] The driving member 116 is a motor.

[0055] Since the support member moves along the connecting rod 111, the cutting mechanism can be driven to move along the connecting rod 111, so that it is possible to cut a large area or even the entire plate to be cut without moving the entire device.

[0056] Moreover, through the driving of the driving member 116, the cutting speed can be balanced, the cutting surface can be made smooth and flat, the cutting quality can be improved, and the workload of later grinding can be reduced.

[0057] The cutting mechanism includes a mounting member detachably connected to the support member and a cutting member provided on the mounting member.

[0058] The mounting member can move relative to the support member to move the cutting member closer to or farther from the connecting member, so that the cutting member can be closer to or farther from the opening of the connecting member.

[0059] Specifically, the mounting member includes two sliders 121, two locking nuts 122 and two locking pins 123.

[0060] The two sliders 121 are fixed on the opposite sides of the cutting member, and the two sliders 121 are respectively sleeved on the two support rods 114 and can slide relative to the support rods 114. Specifically, the cross-section of the support rod 114 is square, so the cross-section of the slider 121 is square. And the two ends of the slider 121 are open and hollow inside.

[0061] Through holes are formed on the outer side surfaces of the sliders 121. The through holes communicate with the inside of the sliders 121.

[0062] The two locking nuts 122 are arranged corresponding to the two sliders 121. The locking nuts 122 are fixed on the side surfaces of the sliders 121 and are located on the outer periphery of the through holes. That is, the locking nuts 122 are fixed on the opposite side surfaces of the two sliders 121.

[0063] The two locking pins 123 are arranged corresponding to the two sliders 121. The locking pins 123 are inserted through the through holes and are screwed with the locking nuts 122.

[0064] Wherein, the locking pin 123 abuts against the support rod 114 to realize the locking of the support rod 114 and the slider 121.

[0065] The connection mode of the mounting member and the support member of the connection mechanism is as follows:

[0066] The two sliders 121 are respectively sleeved on the two support rods 114 one by one. After the sliders 121 are adjusted to the preset positions, the locking pins 123 are rotated. The locking pins 123 are screwed with the locking nuts 122 until the locking pins 123 abut against the support rods 114. And the locking pins 123 are further rotated to ensure the relative fixation between the sliders 121 and the support rods 114.

[0067] The disconnection method between the installation part and the support part of the connection mechanism is as follows:

[0068] Rotate the locking pin 123 to move the locking pin 123 away from the support rod 114 until the slider 121 can move relative to the support rod 114. Then move the slider 121 away from the connecting part to disengage the slider 121 from the support rod 114, thereby disconnecting the connection between the cutting mechanism and the connection mechanism, making the two independent of each other, reducing the volume of the independent individual, and thus facilitating handling.

[0069] When rotating the locking pin 123, it is preferably to provide support to the cutting part to prevent the slider 121 from dropping downward and causing the cutting part to drop when the locking pin 123 retreats from the support rod 114, so as to better protect the cutting part.

[0070] Furthermore, scale marks are also provided on the support rod 114 for the operator to accurately know the position of the slider 121.

[0071] The installation part further includes two handles 124. The two handles 124 are arranged in one-to-one correspondence with the two locking pins 123. Specifically, the handle 124 is arranged at the end of the locking pin 123 away from the locking nut 122 for the convenience of the operator's operation.

[0072] In other embodiments, the installation part can also be detachably connected to the support part by means of clamping or screwing. Exemplarily, for example, a clamping groove is provided on the support rod 114, and the installation part includes a clamping block adapted to the clamping groove. Multiple clamping grooves can also be provided at intervals on the support rod 114 to be able to adjust the distance between the installation part and the connecting part. A connecting hole can also be provided on the support rod 114, and a mounting hole is provided on the installation part, and the fastener passes through the connecting hole and the mounting hole at the same time to achieve detachable connection.

[0073] The cutting part is arranged between the two sliders 121. Specifically, the cutting part includes a housing 125, two rollers 126, a cutting saw blade 127, and a cutting power part 128.

[0074] The opposite ends of the housing 125 are respectively fixedly connected to the sliders 121. It is defined that the sliders 121 are arranged at both ends of the housing 125 in the length direction.

[0075] The interior of the housing 125 has an accommodation space. At least part of the bottom of the housing 125 is open. And the opening at the bottom of the housing 125 communicates with the accommodation space.

[0076] The two rollers 126 are arranged at intervals along the length of the housing 125. The two rollers 126 are located in the accommodation space of the housing 125.

[0077] The cutting saw blade 127 is wound around the outer circumferences of the two rollers 126. The bottom of the cutting saw blade 127 is exposed through the opening at the bottom of the housing 125 for cutting the plate to be cut.

[0078] The cutting power member 128 is connected to one of the rollers 126 to drive it to roll, thereby causing the cutting saw blade 127 to rotate around the two rollers 126. The other roller 126 is rotatably connected to the housing 125 through a tensioning switch.

[0079] Specifically, the cutting power member 128 is fixed to the side surface of the housing 125. And the cutting power member 128 is correspondingly arranged at the side of the roller 126 and connected to the roller 126 to drive it to rotate, thereby driving the other roller 126 to rotate.

[0080] In this embodiment, the cutting power member 128 is a motor, and its output shaft is connected to the roller 126 to drive the roller 126 to rotate.

[0081] Please refer to Figure 3 , the side surfaces of the two opposite ends of the housing 125 near the connecting member have an arc surface, and the convex surface of the arc surface faces the connecting member. The arc surface is closer to the connecting member than the mounting member.

[0082] That is, the mounting member can move to the closest position to the connecting member, and at this time, the arc surface can avoid interference with the connecting member.

[0083] Specifically, when the slider 121 descends along the support rod 114, the side surface of the housing 125 near the connecting member can avoid the connecting rod 111 and get as close as possible to the plate to be cut. Therefore, the root of the cutting surface of the cutting member can be minimized to 1 mm, reducing the workload of later grinding and root cleaning.

[0084] In this embodiment, the slider 121 is fixed to the middle area of the housing 125 along the direction of approaching or departing from the connecting member. In other embodiments, the slider 121 can also be fixed to the end of the housing 125 away from the connecting member. It is specifically set according to actual needs.

[0085] The portable cutting device 1 further includes a cooling water mechanism. The cooling water mechanism includes a water outlet, which is correspondingly arranged for the cutting member and used to supply cooling water to the cutting member during operation.

[0086] That is, when the cutting saw blade 127 is cutting, cooling water is supplied to the cutting saw blade 127 through the cooling water mechanism to reduce the temperature of the cutting saw blade 127 and prevent the cutting saw blade 127 from overheating. Therefore, by changing the cutting method, the cutting operation is changed from hot cutting to cold cutting, reducing the damage to the paint, further reducing the paint repair area, and saving materials and time.

[0087] Taking the cutting of the H606 outer plate scaffolding eye plate by the portable cutting device 1 as an example for illustration.

[0088] Installation: Place the connecting mechanism at the eye plate to be cut, position the cutting structure at the starting position to be cut, adjust the distance between the tracks, and adjust the position of the slider 121 on the support rod 114 to adjust the root height of the cutting saw blade 127. Rotate the rotary switch of the magnetic suction seat 113 and fix it by magnetic suction of the magnetic suction seat 113.;

[0089] Cutting: Start the cutting power component 128 and start the driving component 116. The cutting saw blade 127 starts to cut and moves uniformly along the connecting rod 111. At the same time, use cooling water to cool the cutting saw blade 127.

[0090] Recovery: After cutting is completed, disassemble and recover the cutting mechanism and the track mechanism.

[0091] Specifically, turn off the cutting power component 128 and turn off the driving component 116. Rotate the locking nut 122 to move it away from the support rod 114, thereby releasing the locking between the slider 121 and the support rod 114. Move the slider 121 away from the connecting piece until the slider 121 disengages from the support rod 114, and the connection between the cutting mechanism and the track mechanism is released, so that they can be carried and recycled separately.

[0092] Root cleaning: Use a grinding machine to grind the root of the eye plate cutting until it is flush with the deck, and the cutting operation ends.

[0093] In summary, the portable cutting device 1 has the following advantages:

[0094] 1. The connection between the connecting mechanism and the cutting mechanism of the portable cutting device 1 is detachable, so it can be carried separately, is easy to move, and is convenient for manual handling and movement.

[0095] 2. The structure of the whole device is simple, easy to install and maintain, and can be quickly mastered.

[0096] 3. By adding a cooling water mechanism, the cutting method is changed, so that the cutting operation is changed from hot cutting to cold cutting, reducing the area of paint repair.

[0097] 4. Through the arc design of the installation part and the outer shell 125 of the cutting part, the root of the cutting surface of the whole device can be minimized to 1 mm, reducing the workload of later grinding and root cleaning.

[0098] 5. Through the movable connection between the connecting rod 111 and the support rod 114 and the setting of the driving component 116, the cutting speed can be balanced, the cutting surface can be smooth and flat, the cutting quality can be improved, and the workload of later grinding can be reduced.
