DETAILED DESCRIPTION

[0031] In order to facilitate solving the problems described in the background technology, the embodiment of the patent of the present invention provides a portable rail laser cutting device. The technical scheme in the embodiment of the patent of the present invention will be clearly and completely described below in combination with the drawings in the embodiment of the patent of the present invention. Obviously, the described embodiment is only a part of the embodiment of the patent of the present invention, not all of the embodiments. Based on the embodiments in the patent of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the patent of the present invention.

[0032] See also Figure 1-9 , this embodiment provides a portable rail laser cutting device, comprising:

[0033] The cutting device 300 is arranged on the surface of the tank body and cuts the tank body;

[0034] The track mechanism 100 is arranged on the surface of the tank body to provide support for the cutting device 300;

[0035] The moving mechanism 200 is arranged on the track mechanism 100 and drives the laser cutting device to move;

[0036] The track mechanism 100 includes a first fixing plate 101, which is located at the starting end 103 of the track mechanism 100; a second fixing plate 102, which is located at the terminal end 104 of the track mechanism 100; a fixing hole 105, which is arranged on the surface of the first fixing plate 101 and the second fixing plate 102; a track connecting plate 106, which is connected to the second fixing plate 102; a third fixing plate 107, which is connected to the first fixing plate 101 and connected to the track connecting plate 106; a fixing block 111, which is arranged on the surface of the track connecting plate 106 and the third fixing plate 107; and a protrusion 112, which is arranged on the upper top and the lower top of the fixing block 111.

[0037] The first fixing plate 101, the second fixing plate 102, the third fixing plate 107 and the track connecting plate 106 are connected by cooperating with each other through the latch rod 113 and the latch groove 114. The track connecting plates 106 participating in the connection can be increased or decreased according to the actual size of the tank body; the latch rod 113 can lift the latch groove 114 to ensure that the connected track connecting plate 106 will not fall off.

[0038] Specifically, the fixing block 111 is arranged on the surface of the track connecting piece 106 and the third fixing piece 107, and covers the upper surface of the pin slot 114 connected to the track connecting piece 106 and the third fixing piece 107, which can reduce the distance between the track connecting piece 106 and the track connecting piece 106, and between the track connecting piece 106 and the fixing block 111 on the surface of the third fixing piece 107, thereby reducing the distance between the protrusions 112 and the protrusions 112, and preventing the locking wheel 201 from breaking when it moves to two adjacent protrusions 112.

[0039] Specifically, the thickness of the first fixing plate 101 and the second fixing plate 102 in the vertical direction is greater than the sum of the thickness of the third fixing plate 107 and the fixing block 111 in the vertical direction; the thickness of the first fixing plate 101 and the second fixing plate 102 in the vertical direction is greater than the sum of the thickness of the track connecting plate 106 and the fixing block 111 in the vertical direction, which can prevent the moving mechanism 200 from rushing out of the track when it moves to the end on the track, and the thickness of the first fixing plate 101 and the second fixing plate 102 in the vertical direction can make the moving mechanism 200 stop at the starting end 103 and the end end 104.

[0040] Specifically, the mobile mechanism 200 includes a locking wheel 201, which is arranged at the upper and lower top ends of the fixed block 111; a locking groove 202, which is arranged on the locking wheel 201; a protrusion 112 is arranged inside the locking groove 202; the locking wheel 201 prevents the mobile mechanism 200 from deviating from the track by locking the protrusion 112, so that the mobile mechanism 200 can move normally; a rotating bracket 203, which is connected to the axis of the rotating shaft 204 of the locking wheel 201; and a rotating shaft 204, which is arranged at the center of the rotating shaft 204 of the rotating bracket 203. The connecting rod 205 is connected to the rotating shaft 204 and is arranged on the surface of the rotating shaft 204; the mobile platform 206 is arranged above a plurality of the connecting rods 205; the telescopic rod 207 is arranged on the mobile platform 206 to ensure that the driving wheel 208 can move up and down and always be close to the track mechanism 100; the driving wheel 208 is arranged in the middle position of a plurality of the telescopic rods 207; the driving motor 209 is arranged on the rotating shaft 204 of the driving wheel 208;

[0041] The width of the locking groove 202 is slightly larger than the thickness of the protrusion 112 in the vertical direction. When the track connecting piece 106 is bent, the protrusions 112 are not in a straight line. At this time, when the locking wheel 201 wants to pass through the gap between the protrusions 112, the locking groove 202 needs to have a certain width, and it is necessary to ensure that the width of the locking groove 202 is not too large to cause the locking wheel 201 to detach from the protrusion 112.

[0042] Specifically, the diameter of the locking wheel 201 is larger than the distance between two adjacent protrusions 112 to prevent the locking wheel 201 from being detached from the connecting gap between the two protrusions 112 due to being too small, and the thickness of the locking wheel 201 is also larger than the distance between two adjacent protrusions 112 to prevent the locking wheel 201 from being stuck between two adjacent protrusions 112 when moving.

[0043] Specifically, the gap between the locking wheel 201 and the fixing block 111 is smaller than the height of the protrusion 112, ensuring that the vertically symmetrical locking wheel 201 can fix the mobile mechanism 200 on the track mechanism 100 and the mobile mechanism 200 will not fall off the track mechanism 100 during movement.

[0044] Specifically, the cutting equipment 300 includes a laser generator 304, which is arranged on the mobile platform 206; a telescopic laser head 301, which is arranged below the laser generator 304; a connecting line 302, which is arranged above the telescopic laser head 301; a radiator 303, which is arranged above the mobile platform 206 and connected to the laser generator 304; the rest of the laser cutting device, such as the control mechanism, auxiliary mechanism, etc., are all arranged on the ground to reduce the pressure on the track mechanism 100.

[0045] Example:

[0046] Before the cutting device 300 works, a preliminary estimate is made of the cutting object. Considering the production safety, the device should not complete the solid segmentation task in one time. It is safer and more reliable to divide the ring cutting task into three or four times.

[0047] Different numbers of track connecting plates 106 are selected for assembly according to the length of a single cut. Before the assembly begins, the second fixing plate 102 is taken out first. Since the segmentation work only needs to separate the tank body for easy transportation, high precision is not required. Therefore, the level of the second fixing plate 102 can be judged by visual inspection. After the level judgment is completed, the fixing holes 105 on the second fixing plate 102 are fixed to the surface of the tank body by drilling tools such as bolts.

[0048] After the two fixing holes 105 on the second fixing plate 102 are fixed, the track connecting plate 106 is connected to the second fixing plate 102. The latch slot 114 of the track connecting plate 106 is connected to the latch rod 113 of the second fixing plate 102. After the track connecting plate 106 is fixed, the latch slot 114 of the next track connecting plate 106 is connected to the latch rod 113 of the previous track connecting plate 106. By analogy, the selected track connecting plates 106 are connected in sequence. After all the track connecting plates 106 are installed, the latch slot 114 of the third fixing plate 107 is connected to the latch rod 113 of the last track connecting plate 106. At this time, the mobile mechanism 200 is inserted into the track mechanism 100 from the third fixing plate 107, and the mobile platform 206 is moved to the second fixing plate 102 at the terminal end 104. During the insertion process, the locking wheel 201 is aligned with the protrusions 112 provided on the upper and lower top ends of the fixing block 111, so that the protrusions 112 are located in the locking grooves 202 on the locking wheel 201. After the mobile mechanism 200 enters the track mechanism 100, the latch rod 113 of the first fixing plate 101 is connected to the latch groove 114 of the third fixing plate 107, and the first fixing plate 101 is fixed to the surface of the tank body using bolts or other fixing devices, thereby completing the assembly of the track mechanism 100.

[0049] Move the mobile platform 206 of the mobile mechanism 200 to the starting end 103 of the track mechanism 100, and turn on the control device and auxiliary device of the laser cutting device set on the ground. Data and energy are transmitted to the cutting device 300 on the mobile platform 206 through the connecting line 302. Start the laser generator 304, and the cutting light is emitted through the telescopic laser head 301; the cutting device 300 dissipates heat through the radiator 303.

[0050] After the cutting device 300 is started, the driving motor 209 is turned on. The driving wheel 208 located in the horizontal moving direction of the mobile platform 206 starts to move. The telescopic rod 207 connected to the driving wheel 208 ensures that the driving wheel 208 can always contact the fixed block 111 on the upper surface of the track mechanism 100, ensuring the smooth movement of the mobile mechanism 200.

[0051] After starting to move, the locking wheel 201 moves on the fixed block 111 at the same time. Because the track mechanism 100 around the surface of the tank body is arc-shaped, the rotating shaft 204 set on the rotating bracket 203 connected to the locking wheel 201 helps the locking wheel 201 to rotate, so as to adapt to the movement on the fixed block 111. The protrusion 112 located in the locking groove 202 can ensure that the mobile mechanism 200 will not fall off the track mechanism 100. And the locking wheel 201 can smoothly pass through the gap between the protrusions 112 and will not fall off from the analysis. The rotating shaft 204 is connected to the mobile platform 206 through the connecting rod 205, and the locking wheel 201 is symmetrically arranged at the upper top and the lower top of the mobile platform 206 to ensure that the locking of the track mechanism 100 is completed.

[0052] After the cutting work is completed, the cutting device 300 will stay at the terminal end 104. After removing the bolts on the first fixing plate 101 of the moving mechanism 200, the cutting mechanism and the moving mechanism 200 are taken out from the track mechanism 100. After the removal is completed, the second fixing plate 102 is grasped, and the bolts on the second fixing plate 102 are removed, and the track connecting plate 106 connected to the second fixing plate 102 can be completely removed, so as to realize the rapid removal of the track mechanism 100. The track mechanism 100 is disassembled into individual track connecting plates 106 for storage, so as to achieve the purpose of portability. Although the embodiments of the patent of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the patent of the present invention, and the scope of the patent of the present invention is defined by the attached claims and their equivalents.
