[0002] A storage rack refers to a horizontal platform device used for collecting, stacking, handling and transporting goods. It is placed on the ground and serves as a load-bearing surface for the goods. During the processing and production of existing metal storage racks, different structural parts often need to be fixedly connected by welding to form the main frame. In order to ensure the structural strength of the welding, the welding surface of the structural parts of the storage rack needs to be derusted before welding to ensure the flatness of the welding surface.

[0003] At present, the structural parts used for welding storage racks mainly include installation pipes of different lengths and specifications. Before welding these installation pipes, the welding factory will use a laser rust removal machine to remove the rust on the installation pipes using a laser head. When operators are preparing for laser rust removal, in order to ensure the stability of the installed pipes during the rust removal process, they often need to use fixing devices to clamp and fix the installed pipes. However, during the clamping process, the fixing devices inevitably block the outer wall of the installed pipes, making it impossible for the laser rust remover to completely remove rust from the pipes when it is working. The operator is required to perform secondary processing on the installed pipes, which affects the efficiency of rust removal. Summary of the invention

Adjacent placement plates 41 are connected by transmission connecting rods 43. The placement plate 41 at one end is fixedly installed on one side of the bottom frame 102, and the remaining multiple groups of placement plates 41 are slidably installed on the bottom frame 102, and are driven to move synchronously by the second power assembly 44 installed on the bottom frame 102. Multiple groups of clamping blocks 42 are installed at intervals on the placement plates 41, and the clamping blocks 42 at corresponding positions on the multiple groups of placement plates 41 are used to clamp one The plurality of mounting tubes 3 are provided with a placement groove for placing the mounting tube 3 in the clamping block 42, and a group of clamping claws 46 are slidably installed on both sides of the placement groove. The distal ends of the two groups of clamping claws 46 are fixedly connected to the corresponding driving plates 471 through connecting columns. The two groups of driving plates 471 are driven by the first driving assembly 47 to move in a mirror image. The first driving assembly 47 in the plurality of clamping blocks 42 is connected by a transmission rod 410. The end of the transmission rod 410 is provided with a transmission block 412 for slidingly abutting the transmission plate 27. The two groups of driving plates 471 are elastically connected to the corresponding control plates 481 through connecting springs 413. The two groups of control plates 48 1 is driven by the second driving assembly 48 to move in a mirror image, and the second driving assembly 48 in the multiple clamping blocks 42 is connected by a driving rod 49. The two groups of limit baffles 45 are respectively rotatably installed on the outer sides of the two groups of placement plates 41, which are elastically connected to the corresponding placement plates 41. The two groups of limit baffles 45 are correspondingly rotatably installed with multiple groups of rotating disks for abutting the ends of the corresponding installation pipes 3, and the multiple groups of rotating disks on one group of limit baffles 45 are driven to rotate synchronously by the corresponding rotating assembly 415; the locking structure 5 is installed on the limit baffle 45 and is connected by a driving rod 47 in the corresponding clamping block 42 to lock the limit baffle 45; Specifically, when the present invention is in use, the installation tubes 3 of the same specification can be placed in the placement grooves of the multiple groups of clamping blocks 42 on the placement plate 41 in sequence, and the second driving components 48 on the multiple groups of placement plates 41 can be controlled to be driven synchronously, and the transmission belt 443 drives the two groups of clamping claws 46 in the placement groove to approach each other in a mirror image, driving the clamping claws 46 to clamp on both sides of the installation tube 3, and at the same time, the multiple groups of movable placement plates 41 are driven to move synchronously through the second power component 44, driving the movable limit baffle 45 on one side to approach the fixed limit baffle 45 on the other side, and the movement of the limit baffle 45 drives the two groups of limit baffles 45 to respectively abut on the end faces of both sides of the installation tube 3, so as to make a final adjustment to the final clamping position of the installation tube 3; Furthermore, when the present invention is performing laser rust removal, the emitting positions of the multiple groups of laser emitters 25 are adjusted by moving the sliding platform 21, and the sliding platform 21 moves along the axial direction of the mounting tube 3, so that the laser emitter 25 performs laser rust removal on the tube body of the mounting tube 3 close to the laser emitter 25. When the sliding platform 21 moves, when it moves to the clamping position of the clamping block 42, the transmission plate 27 on one side of the sliding platform 21 abuts against the transmission block 412 on one side of the placement plate 41, and the transmission plate 27 squeezes the transmission block 412 to move, and then the transmission belt 443 drives the multiple groups of first drive components 47 to move accordingly, so that the two groups of clamping claws 46 on the clamping block 42 for clamping the mounting tube 3 move away in a mirror image, and the mounting tube 3 is loosened, thereby preventing the laser from being blocked by the clamping claws 46 during the rust removal operation, resulting in it being unable to cover the tube body; Moreover, in the present invention, when the sliding platform 21 moves to the end of the mounting tube 3, the locking structure 5 is unlocked, and the transmission plate 27 can abut against the limit baffle 45 at this time. The transmission plate 27 pushes the limit baffle 45 to deflect, and cooperates with the lifting and lowering of the sliding platform 21 and the rotation of the turntable 24 to adjust the direction of the laser by 90°, so that the laser can perform laser rust removal on the end surface of the mounting tube 3.

[0026] like Figure 2 As shown, in the embodiment of the present invention, the first power assembly 23 includes a driving screw 231 and a plurality of guide rods 232, wherein the driving screw 231 is rotatably mounted on the top frame 101 and is threadedly connected with a fixed inner screw installed on the sliding platform 21, the driving screw 231 is driven to rotate by a first control motor installed on the top frame 101, and the plurality of guide rods 232 are fixedly mounted on the top frame 101 and are slidably connected with the sliding platform 21. When the present invention realizes the movement of the sliding platform 21, the first control motor is started to drive the driving screw 231 to rotate, and the driving screw 231 and the fixed inner screw are rotated and transmitted to drive the sliding platform 21 to move linearly along the guide direction of the top frame 101; And, in the present invention, the sliding platform 21 includes a sliding top plate 211 and a sliding bottom plate 212, wherein the sliding top plate 211 is transmission-connected to the first power assembly 23, and the sliding bottom plate 212 is transmission-connected to multiple groups of lifting cylinders 22 on the sliding top plate 211, and the lifting cylinders 22 are extended and retracted to adjust the working height of the sliding bottom plate 212, and the turntable 24 is rotatably installed at the bottom of the sliding bottom plate 212; Further, such as Figure 1 As shown, the two sides of the turntable 24 are rotatably mounted on the sliding platform 21 through the mounting shafts, the rotating member is a second control motor 26, one set of the mounting shafts is transmission-connected with the second control motor 26, and the mounting shafts are driven to rotate by the second control motor 26, which drives the turntable 24 to rotate synchronously, and adjusts the emission angle of the laser emitter 25 of the turntable 24; In the present invention, when the sliding platform 21 moves to the end of the mounting tube 3, the second control motor 26 controls the turntable 24 to rotate, and the pointing angle of the laser is adjusted to 90°. At the same time, the lifting cylinder 22 is lifted and lowered to drive the lifting base plate to move, so that the laser can perform laser rust removal on the end surface of the mounting tube 3.

[0027] like Figure 4 As shown, in the embodiment of the present invention, the transmission connecting rod 43 includes four groups of connecting rods 431, and the four groups of connecting rods 431 are sequentially connected end to end in a stroke quadrilateral structure, and the two ends of the transmission connecting rod 43 are respectively rotatably connected to the bottom of two adjacent groups of placement plates 41. The present invention uses multiple groups of transmission connecting rods 43 to transmit and connect multiple groups of parallel sliding placement plates 41. When the second power component 44 drives one group of limit baffles 45 to move closer to the limit baffle 45 on the other side, the multiple groups of transmission connecting rods 43 are correspondingly rotated, so that during the synchronous movement of the multiple groups of placement plates 41, the distance between the two adjacent groups of placement plates 41 remains consistent, so that the multiple groups of clamping blocks 42 can be evenly clamped on the pipe body of the installation pipe 3; Furthermore, a group of abutment pulleys are respectively installed at both ends of the arc-shaped clamping plate of the clamping claw 46 of the present invention, and two pairs of abutment pulleys are provided on a group of clamping claws 46 for clamping the installation pipe 3; Furthermore, the second power assembly 44 includes two groups of rotating columns 441 and threaded sleeves 442. The two groups of rotating columns 441 are fixed in parallel on both sides of the bottom frame 102 and are slidably connected with the two ends of the plurality of groups of placement plates 41 that are movably installed. The end sides of the two groups of rotating columns 441 are connected by transmission belts 443, wherein one group of fixed rods is driven to rotate by the corresponding third control motor 444. The two groups of threaded sleeves 442 are coaxially fixedly installed at one end of the rotating column 441 away from the fixed placement plate 41, and form a spiral pair transmission with the placement plate 41 at the same end that is located at the outermost end. The present invention starts the third Control the single machine, the third control motor 444 drives the corresponding connected rotating column 441 to rotate, and the transmission belt 443 drives the two groups of rotating columns 441 and the threaded sleeve 442 on the rotating column 441 to rotate synchronously, and the transmission belt 443 drives the threaded sleeve 442 and its stroke spiral pair to drive the outermost placement plate 41 to move, thereby realizing the movement of multiple groups of placement plates 41 and two groups of limit baffles 45. Of course, the second power component 44 can also be preferably other driving components that can be used to drive the linear movement of the outermost placement plate 41, such as a gear rack structure or a cylinder telescopic structure, etc.

[0028] like Figure 5 As shown, in the embodiment of the present invention, the first driving assembly 47 includes a No. 1 driving gear 472 and two groups of No. 1 transmission toothed plates 473. The No. 1 driving gear 472 is rotatably mounted in the clamping block 42. The two groups of No. 1 transmission toothed plates 473 are respectively mounted at the bottom of the two groups of driving plates 471 and meshed on both sides of the No. 1 driving gear 472. The transmission rod 410 is fixedly mounted at the bottom of the lower driving plate 471, and one end extends out of the outermost clamping block 42 and is fixedly connected to the transmission block 412. In the present invention, when the transmission plate 27 is moved by the sliding plane When the platform 21 is driven to move in the direction close to the clamping block 42, the transmission plate 27 squeezes the transmission block 412 to move in the direction close to the clamping block 42, and then the transmission belt 443 drives the correspondingly connected transmission rod 410 to move accordingly, so that the two groups of clamping claws 46 on the clamping block 42 for clamping the mounting tube 3 move away from each other in a mirror image, thereby loosening the mounting tube 3. During the laser rust removal operation, the transmission plate 27 keeps pressing the transmission block 412, and keeps the clamping claws 46 loosening the mounting tube 3 until the transmission plate 27 and the transmission block 412 are separated.

[0029] like Figure 6 and Figure 7As shown, in the embodiment of the present invention, the locking structure 5 includes a locking pin 56, a locking tube 53, a rotary inner nut 51 and a transmission stud 55. The locking pin 56 is slidably mounted on a limit plate 52 arranged on one side of the clamping block 42 close to the limit baffle 45. The limit plate 52 is slidably connected to the outer wall of the clamping block 42 through a telescopic connecting rod 54. The locking tube 53 is fixedly mounted on one side of the limit baffle 45, and is provided with a limit hole for positioning and inserting the limit pin. The rotary inner nut 51 is rotatably mounted on one side of the clamping block 42 and is coaxially fixedly connected to the No. 1 driving gear 472. The outer wall of the clamping block 42 is provided with a mounting hole for rotatably connecting the rotary inner nut 51. One end of the transmission stud 55 is fixedly connected to the limit plate 52, and the other end forms a spiral pair transmission with the rotary inner nut 51. In the present invention, when the transmission plate 27 is away from the limit baffle 45, the clamping block 42 on the placement plate 41 close to the limit baffle 45 clamps the mounting tube 3, and the locking pin 56 on the limit plate 52 corresponds to enter and exit the locking tube 53. The limit of the locking pin 56 and the locking tube 53 prevents the limit baffle 45 from being affected by the squeezing force when clamping the end of the mounting tube 3, and deflection and rotation occur. At this time, the two sets of limit baffles 45 can achieve the clamping effect of resisting the two ends of the mounting tube 3. When the transmission plate 27 moves close to the limit baffle 45, the transmission plate 27 needs to first contact the transmission block 412 on the placement plate 41 close to the limit baffle 45, and in the process of squeezing the transmission block 412, drive the No. 1 driving gear 472 to rotate, and drive the rotating inner nut 51 coaxially connected thereto to rotate, and the transmission belt 443 drives the transmission stud 55 to retract into the clamping block 42, while driving the limit plate 52 and the locking pin 56 to move in the direction close to the clamping block 42, and the locking pin 56 is separated from the locking tube 53. At this time, the limit baffle 45 can be further The moving transmission plate 27 is squeezed to deflect and displace, and the return spring 414 for elastically connecting the limit baffle 45 and the placement plate 41 is stretched accordingly. The tension of the return spring 414 maintains the pressing state between the transmission plate 27 and the limit baffle 45, and when the transmission plate 27 is reset and retreated, the limit baffle 45 is pulled back to a vertical state by the tension of the return spring 414. In the present invention, when the limit baffle 45 is reset, the fixed column 416 installed on the outer side of the placement plate 41 abuts against the inner side of the limit baffle 45 to keep the limit baffle 45 stable. like Figure 5 and Figure 6 As shown, in the embodiment of the present invention, the transmission block 412 is a semicircular fan-shaped structure. When the transmission plate 27 contacts the side of the transmission block 412, it can further move along the curved side of the transmission block 412 and squeeze the transmission block 412 to passively displace. Of course, in actual design, the transmission block 412 can also be designed as a trapezoidal structure with inclined surfaces on both sides. The present invention does not impose a rigid limitation on the specific structure of the transmission block 412.

[0030] like Figure 5 and Figure 7 As shown, in the embodiment of the present invention, the second driving assembly 48 includes a No. 2 driving gear 482 and two sets of No. 2 transmission gear plates 483. The No. 2 driving gear 482 is rotatably mounted in the clamping block 42. The two sets of No. 2 transmission gear plates 483 are respectively mounted at the bottom of the two sets of control plates 481 and meshed at both sides of the No. 2 driving gear 482. The driving rod 49 is fixedly mounted at the bottom of the lower control plate 481 and is driven to move by the telescopic cylinder 411. In the present invention, when the installation tubes 3 are placed in sequence, the telescopic cylinders 411 on the multiple sets of placement plates 41 can be controlled to shrink synchronously, driving the multiple sets of driving rods 49 and the control plates 481 correspondingly connected to the driving rods 49 to move synchronously, and cooperate with the transmission of the No. 2 driving gear 482 and the two sets of No. 2 transmission gear plates 483 to drive the two sets of control plates 481 to move in a mirror-image manner, and the two sets of driving plates 471 are elastically pulled in a mirror-image manner by the connecting spring 413, driving the clamping operation of the two sets of clamping claws 46; In the present invention, the second driving assembly 48 for realizing the mirror-image movement of the two sets of control plates 481 may also be made of other components that meet this function, such as a double-headed screw structure, etc.

[0031] like Figure 1 As shown, in the embodiment of the present invention, the rotating assembly 415 includes a rotating shaft 4151, multiple groups of transmission worm wheels 4152 and a driving worm 4154. The rotating shaft 4151 is rotatably mounted on one side of the limit baffle 45 and driven to rotate by the fourth control motor 4153. Multiple groups of driving worms 4154 are coaxially fixedly mounted on the outer side of the rotating shaft 4151. Multiple groups of transmission worm wheels 4152 are coaxially fixedly mounted on the outer side of the rotating disk and mesh with the corresponding driving worms 4154 for transmission. In the present invention, after the laser emitter 25 completes the laser rust removal operation on one side of the installation tube 3, when the sliding platform 21 retreats, so that the transmission plate 27 is out of contact with the two sets of limit baffles 45, the fourth control motor 4153 can be used to control the rotation of the rotating shaft 4151, and cooperate with the transmission worm gear 4152 and the drive worm 4154 to drive multiple sets of turntables to rotate 180°, thereby realizing a 180° flip of the installation tube 3, avoiding the need for personnel to perform rotation adjustment of the installation tube 3.

[0032] In this solution, a controller is also provided on the bracket 1. When in use, each electrical device can be started and operated separately through the controller. The power connection method of each electrical device is an existing mature technology, and the control circuit of the controller can be realized by simple programming by technicians in this field. These are all well-known technologies in this field and will not be elaborated here.

[0033] In summary, the present invention designs the rust removal mechanism 2, the clamping structure 4 and the locking structure 5 on the upper and lower sides of the bracket 1, so that when the present invention is used: 1. After the operator places the installation tubes 3 of the same specifications in the placement grooves on the placement plate 41 in sequence, the second driving assembly 48 and the second power assembly 44 are started to control the clamping claws 46 on the multiple clamping blocks 42 to clamp on both sides of the installation tube 3, and drive the two groups of limit baffles 45 to abut on the end surfaces of both sides of the installation tube 3, so as to meet the automatic synchronous positioning and clamping of the installation tubes 3 of the same length specifications; 2. When the laser rust removal operation is performed on the body of the installation tube 3, the sliding platform 21 is controlled to move along the axial direction of the installation tube 3, so that the laser emitter 25 performs laser rust removal on the body of the installation tube 3 close to the laser emitter 25, and when the laser emitter 25 moves to the clamping position of the clamping block 42, the transmission plate 27 on one side of the sliding platform 21 squeezes the transmission block 412 to move, and then the transmission belt 443 moves the clamping claw 46 close to the clamping block 42 to loosen the installation tube 3, thereby preventing the laser from being blocked by the clamping claw 46 during the rust removal operation, resulting in its inability to cover the tube body; 3. When laser rust removal is performed on the end faces of both sides of the mounting tube 3, when the sliding platform 21 moves to the end of the mounting tube 3, the transmission plate 27 first contacts the transmission block 412 on the placement plate 41 close to the limit baffle 45, and controls the clamping claw 46 on the clamping block 42 to loosen the mounting tube 3. At the same time, the transmission belt 443 drives the locking pin 56 to move toward the direction close to the clamping block 42, so that the locking pin 56 is disengaged from the locking tube 53. At this time, the limit baffle 45 can be further squeezed by the transmission plate 27 to be deflected and displaced, and in conjunction with the lifting and lowering of the sliding platform 21 and the 90° rotation of the turntable 24, the laser emitter 25 is adjusted to point to the end face of the mounting tube 3, and the end face is laser rust removed.

[0034] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
