[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, a fixing mechanism is provided between the two mounting plates. During the construction of rail installation, the fixing mechanism can be used to support and fix the rail, and then the universal wheel moving device can be used to transport the rail. Thus, this device can assist the construction workers to move and transport the rail. And when the rail is placed on the placing plate, the worm can be rotated to drive the two lead screws on the same placing plate to rotate forward by the worm gear. When the lead screws rotate forward, the front and rear first clamping plates are driven to approach each other. When the first clamping plates are both in contact with the rail body, stop rotating the worm. Thus, the rail body is clamped and fixed by the first clamping plates, effectively improving the stability of the rail body during the transportation process.

[0015] In the present invention, a loading and unloading mechanism is provided above the fixing mechanism. When using this device to transfer the rail body, the user can control the operation of the second motor through the controller to drive the rotation of two second screws by means of the third sprocket. When the second screws rotate, they drive the translation frame, the third fixing frame, and the second clamping plate to move back and forth through the third screw holes. When the third fixing frame moves between the two fixing mechanisms, stop the operation of the second motor, and then control the extension of the second electric push rod to make the third fixing frame and the second clamping plate descend. When the second clamping plate corresponds to the rail body on the ground and the two second clamping plates are respectively located on the front and rear sides of the rail body, stop the extension of the second electric push rod. At this time, the user can control the extension of the third electric push rod to push the two second clamping plates to approach each other to clamp the rail body, and then can use the contraction of the second electric push rod to lift the rail body, and use the second motor and the second screw to drive the translation frame and the fixing frame to move back and forth to move the rail body above the placement plate, so as to place the rail body on the placement plate for fixation. Therefore, when using this device to transfer the rail body, the loading and unloading mechanism can assist the construction workers to hoist and load and unload the rail body, effectively improving the loading and unloading efficiency of the rail body and reducing the workload of the construction workers.

[0016] In the present invention, a grinding mechanism is provided above each fixing mechanism. When using the fixing mechanism to fix the rail body, the user can control the operation of the first motor to drive the rotation of the connecting shaft five and the third gear through the second gear and the fourth gear. When the third gear rotates, it rolls along the toothed plate to drive the sliding frame to slide left and right. When the sliding frame drives the grinding disc to move to correspond to the right end of the rail body, stop the operation of the first motor, and control the extension of the first electric push rod to make the upper grinding disc contact the upper end of the rail body, and control the operation of the double-shaft motor to make the front and rear grinding discs approach each other and contact the side surfaces of the rail body. Then the user can control the operation of the first motor again to make the sliding frame translate to the left. When the first motor operates, the three grinding discs are driven to rotate through the transmission of relevant structures, so as to grind the rust spots on the outer surface of the rail body while the grinding disc translates while fitting the rail body, which is beneficial to subsequent welding and other processes of the rail body during rail installation construction, and performing the grinding process during the transfer process can effectively improve the construction efficiency.

[0017] In the present invention, a first fixing frame is provided on the right side of the sixth fixing plate, and the second fixing frame and the spray pipe are connected to the first fixing frame. When controlling the operation of the first motor to drive the grinding disc to rotate to grind the rail body, the user can control the operation of the water pump to suck out the cleaning liquid or the rust preventive liquid in the liquid storage tank and input it into the spray pipe, and then spray the cleaning liquid or the rust preventive liquid on the contact surface between the grinding disc and the rail body through the spray pipe, so as to wash the debris ground off by the grinding disc to ensure the treatment effect on the rail body, and at the same time can also spray the rust preventive liquid on the rail body to improve the rust prevention ability of the rail body, further increasing the functionality of this device.

When the water pump 618 works, it sucks out the cleaning liquid or the rust-proof liquid in the liquid storage tank 62 and inputs it into the spray pipe 625, and then sprays the cleaning liquid or the rust-proof liquid on the contact surface between the grinding disc 611 and the rail body 54 through the spray pipe 625, flushing the debris ground off by the grinding disc 611 to ensure the treatment effect on the rail body 54. At the same time, it can also spray the rust-proof liquid on the rail body 54 to improve the rust-proof ability of the rail body 54, further increasing the functionality of this device.

[0029] The loading and unloading mechanism 7 includes two mounting frames 71. The bottom surfaces of the two mounting frames 71 are respectively fixedly connected to the upper surfaces of the two mounting plates 1. The upper ends of the two mounting frames 71 are respectively rotatably connected to the end optical axes of the two screw rods two 73 through bearings. The two screw rods two 73 are respectively threadedly connected to the screw holes three 710. The two screw holes three 710 are respectively opened on the left and right sides of the upper end of the translation frame 74. Four sleeve holes two 79 are also opened at the upper end of the translation frame 74. The four sleeve holes two 79 are respectively sleeved with the four slide rods two 75. The four slide rods two 75 are grouped in pairs, and the two groups of slide rods two 75 are respectively fixedly provided at the upper ends of the two mounting frames 71.

[0030] The front ends of two second screws 73 are respectively fixedly connected to two third sprockets 72. The two third sprockets 72 are connected by chain drive. The front end of the left second screw 73 is fixedly connected to the output shaft of a second motor 78. The second motor 78 is fixedly connected to the front end of the left mounting frame 71 through a mounting seat. The bottom end of the translation frame 74 is simultaneously fixedly connected to the upper ends of two second electric push rods 77. The bottom ends of the two second electric push rods 77 are both fixedly connected to the upper ends of a third fixed frame 76. The front and rear sides of the two third fixed frames 76 are respectively fixedly connected to the opposite ends of two groups of third electric push rods 711. The opposite ends of the two groups of third electric push rods 711 are respectively fixedly connected to the opposite surfaces of two second clamping plates 712. Each group of third electric push rods 711 is composed of two third electric push rods 711. The input ends of the two second electric push rods 77, the two groups of third electric push rods 711 and the second motor 78 are all electrically connected to the output end of a controller 2. When using this device to transport the rail body 54, the user can control the second motor 78 to work through the controller 2, and drive the two second screws 73 to rotate by the third sprocket 72. When the second screws 73 rotate, they drive the translation frame 74, the third fixed frame 76 and the second clamping plates 712 to move back and forth through the third screw holes 710. When the third fixed frame 76 moves between the two fixing mechanisms 5, stop the second motor 78 from working, and then control the second electric push rods 77 to extend, so that the third fixed frame 76 and the second clamping plates 712 descend. When the second clamping plates 712 correspond to the rail body 54 on the ground and the two second clamping plates 712 are respectively located on the front and rear sides of the rail body 54, stop the second electric push rods 77 from extending. At this time, the third electric push rods 711 can be controlled to extend to push the two second clamping plates 712 to approach each other to clamp the rail body 54. Then, the second electric push rods 77 can be contracted to lift the rail body 54, and the second motor 78 and the second screws 73 are used to drive the translation frame 74 and the fixed frame to move back and forth so that the rail body 54 moves above the rail body 54. Then, control the second electric push rods 77 to extend to place the rail body 54 on the placing plate 51 between the two first clamping plates 52. Therefore, when using this device to transport the rail body 54, the loading and unloading mechanism 7 can assist the construction workers to hoist and load and unload the rail body 54, effectively improving the loading and unloading efficiency of the rail body 54 and reducing the workload of the construction workers.

[0031] The operation steps of the present invention are as follows: When using this device to transfer the rail body 54, the user can control the operation of the second motor 78 through the controller 2 to drive the rotation of the two second screws 73 by the third sprocket 72. When the second screws 73 rotate, they drive the translation frame 74, the third fixed frame 76 and the second clamping plate 712 to move back and forth through the third screw holes 710. When the third fixed frame 76 moves between the two fixing mechanisms 5, stop the operation of the second motor 78, and then control the extension of the second electric push rod 77 to make the third fixed frame 76 and the second clamping plate 712 descend. When the second clamping plate 712 corresponds to the rail body 54 on the ground and the two second clamping plates 712 are respectively located on the front and rear sides of the rail body 54, stop the extension of the second electric push rod 77. At this time, control the extension of the third electric push rod 711 to push the two second clamping plates 712 to approach each other to clamp the rail body 54. Then, the contraction of the second electric push rod 77 can be used to lift the rail body 54, and the second motor 78 and the second screws 73 are used to drive the translation frame 74 and the fixed frame to move back and forth so that the rail body 54 is moved above the rail body 54. Then, control the extension of the second electric push rod 77 to place the rail body 54 on the placement plate 51 between the two first clamping plates 52, and control the contraction of the third electric push rod 711 to make the second clamping plates 712 separate from the rail body 54. Then, control the upward movement of the second electric push rod 77 to make the third clamping plate move above the rail body 54, and control the operation of the second motor 78 to make the third fixed frame 76 move between the two placement plates 51 again; Then, the user can rotate the worm 512 to drive the positive rotation of the two lead screws 510 on the same placement plate 51 by the worm gear 511. When the lead screws 510 rotate positively, they drive the two first clamping plates 52 on the front and rear sides to approach each other. When the first clamping plates 52 are both in contact with the rail body 54, stop rotating the worm 512, and use the first clamping plates 52 to clamp and fix the rail body 54. At this time, the universal wheels 4 can be used to move the device to transfer the rail. During the transfer process, the user can control the operation of the first motor 639 to drive the rotation of the connecting shaft five 643 and the third gear 641 by the second gear 640 and the fourth gear 642. When the third gear 641 rotates, it rolls along the toothed plate 58 to drive the sliding frame 616 to slide left and right. When the sliding frame 616 drives the grinding disc 611 to move to correspond to the right end of the rail body 54, stop the operation of the first motor 639, and control the extension of the first electric push rod 615 to make the upper grinding disc 611 contact the upper end of the rail body 54. Then, control the positive rotation of the output shafts of the double-shaft motor 637 to drive the positive rotation of the two first screws 635. When the two first screws 635 rotate positively, they drive the two fifth fixing plates 610 and the front and rear grinding discs 611 to approach each other through the second screw holes 634. When the front and rear grinding discs 611 are respectively in contact with the front and rear sides of the rail body 54, turn off the double-shaft motor 637; Then, the user can control the operation of the first motor 639 again to move the sliding frame 616 horizontally to the left. When the first motor 639 operates, it drives the rotation of two gear shafts 69, the third connecting shaft 627 and the upper grinding disc 611 through the first bevel gear 63, the second bevel gear 64, the sleeve 65, the sliding plate 619, the first connecting shaft 68, the third bevel gear 620, the fourth bevel gear 621, the fifth bevel gear 626 and the sixth bevel gear 636. When the two gear shafts 69 rotate, they drive the rotation of two fourth connecting shafts 628 and the front and rear grinding discs 611 through the first gear 622, the second connecting shaft 623, the second sprocket 630 and the first sprocket 629. At this time, the rust spots on the outer surface of the rail body 54 are ground by the rotation of the three grinding discs 611. During the grinding process, the user can control the operation of the water pump 618 through the controller 2. When the water pump 618 operates, it sucks out the cleaning liquid or the rust preventive liquid in the liquid storage tank 62 and inputs it into the spray pipe 625, and then sprays the cleaning liquid or the rust preventive liquid on the contact surface between the grinding disc 611 and the rail body 54 through the spray pipe 625 to wash the debris ground off by the grinding disc 611, and at the same time, it can also spray the rust preventive liquid on the rail body 54.
