[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Please see the appendix Figure 1 - Appendix Figure 8 A mounting and fixing device for a double-ear fixed beam includes a base 8. A hydraulic telescopic rod 28 is vertically fixed at the center of the top of the base 8. A mounting box 15 is horizontally fixed at the top of the telescopic end of the hydraulic telescopic rod 28. U-shaped placement racks 6 are provided at both ends of one side of the mounting box 15. L-shaped moving plates 11 are welded to both sides of the two U-shaped placement racks 6. A synchronous moving mechanism is provided inside the mounting box 15 to drive the two sets of U-shaped placement racks 6 and L-shaped moving plates 11 to move synchronously. Screws 7 are rotatably connected through the upper and lower sides of the four L-shaped moving plates 11. A plum blossom head 5 is fixedly connected to the top of the screws 7. Cleaning rollers 29 are horizontally provided on both sides of the two U-shaped placement racks 6. A positioning mechanism for fixing the device position is provided at the top and bottom of the base 8.

[0030] When the device is moved to the position where the double-ear fixed beam needs to be installed, the double-ear fixed beam is placed horizontally on the two U-shaped placement frames 6. The hydraulic telescopic rod 28 is activated to drive the installation box 15 to rise, which in turn drives the double-ear fixed beam on the U-shaped placement frame 6 to rise. There is no need for a crane to lift the double-ear fixed beam, which prevents it from shaking during the rising and installation process and facilitates its installation.

[0031] Please see the appendix Figure 1 and 2 In a preferred embodiment, a push rod 4 is welded obliquely to one side of the base 8, and casters 9 are welded to the four corners of the bottom of the base 8. A battery 1 and a controller 3 are mounted side by side on the top side of the base 8. The push rod 4 is used to push the entire device, and the four casters 9 facilitate the movement of the entire device. The battery 1 supplies power to all electrical equipment, and the controller 3 controls the operation of all electrical equipment.

[0032] Please see the appendix Figure 1 , 3In a preferred embodiment, the synchronous movement mechanism includes a forward and reverse motor 14 and a lead screw 2. The lead screw 2 is horizontally rotatably connected inside the mounting box 15. The forward and reverse motor 14 is horizontally fixedly mounted on one end of the mounting box 15. The output shaft of the forward and reverse motor 14 extends into the mounting box 15 and is fixedly connected to one end of the lead screw 2. The output shaft of the forward and reverse motor 14 is rotatably connected to the mounting box 15. Both ends of the lead screw 2 are fitted with moving blocks 16, and both moving blocks 16 are connected to the lead screw 2 by threads. The threads at both ends of the lead screw 2 are in opposite directions.

[0033] Please see the appendix Figure 1 , 3 In a preferred embodiment, both movable blocks 16 are slidably connected inside the mounting box 15. A first L-shaped connecting rod 13 is welded to one side of each movable block 16. One side of the mounting box 15 is an open structure. Both first L-shaped connecting rods 13 extend from the open side of the mounting box 15. A C-shaped connecting rod 12 is welded to the other end of each first L-shaped connecting rod 13. The bottom ends of the C-shaped connecting rod 12 are respectively welded to the top of the two L-shaped movable plates 11 on both sides of the U-shaped placement frame 6.

[0034] Before raising the double-ear fixed beam, the forward and reverse motor 14 is started to rotate the lead screw 2, causing the two moving blocks 16 to move in opposite directions on the lead screw 2. This, in turn, drives the L-shaped moving plate 11 to move in opposite directions via the first L-shaped connecting rod 13 and the C-shaped connecting rod 12. The L-shaped moving plate 11 then drives the U-shaped placement frame 6 to move in opposite directions until the two U-shaped placement frames 6 are close to both ends of the double-ear fixed beam. At this point, the supporting force on the double-ear fixed beam is more balanced and stable. When the double-ear fixed beam rises to the installation position, the forward and reverse motor 14 is started again, similarly driving the L-shaped moving plate 11. Moving in the opposite direction, the L-shaped moving plate 11 drives the screw 7 to move in the opposite direction, which in turn drives the sprite head 5 at the front end of the screw 7 to move in the opposite direction. This causes the fixing bolt placed on the sprite head 5 to move and rotate at the same time, thus screwing it into the installation position until the double ears of the double ear fixing beam are fixed in the installation position, thereby completing the installation and fixing of the double ear fixing beam. No manual operation is required for installation and fixing, saving time and effort, avoiding workers from climbing to heights and protecting worker safety. The same drive mechanism is used to complete the position adjustment of the U-shaped placement frame 6 and the fixing bolt installation, making the device simpler.

[0035] In a preferred embodiment, the pentagonal head 5 is adapted to the pentagonal groove at the end of the fixing bolt, and the pentagonal head 5 is made of magnetic material.

[0036] After adjusting the position of the U-shaped placement bracket 6, align the plum blossom groove of the fixing bolt with the plum blossom head 5 and place it. The magnetic plum blossom head 5 will attract the fixing bolt to the plum blossom head 5 and prevent it from falling off.

[0037] Please see the appendix Figure 1 ,3 In a preferred embodiment, the inner sides of the four L-shaped movable plates 11 are each provided with a fixed plate 10, and a plurality of screws 7 pass through the four fixed plates 10 and are connected to the fixed plates 10 by threads. The bottom of the two fixed plates 10 on the same side is horizontally welded with the same crossbar 21, one end of the crossbar 21 is welded with an L-shaped fixing rod 20, and the other end of the L-shaped fixing rod 20 is welded to the bottom of the mounting box 15.

[0038] When the screw 7 moves, because the screw 7 and the fixing plate 10 are connected by threads, the screw 7 moves and rotates at the same time. The crossbar 21 and the L-shaped fixing rod 20 connect and fix the two fixing plates 10, so that they rise and fall with the lifting of the mounting box 15.

[0039] Please see the appendix Figure 1 , 3 6, wherein two fixed plates 10 are horizontally rotatably connected to sleeves 31 on one side, and the two sleeves 31 are respectively fitted on the outside of the two screws 7 and connected to the screws 7 by threads. Two cleaning rollers 29 are horizontally rotatably connected to the middle of one side of two fixed plates 10, and belts 30 are connected between the cleaning rollers 29 and sleeves 31 on the same side.

[0040] When the screw 7 moves, since the screw 7 and the sleeve 31 are also connected by threads, the screw 7 drives the sleeve 31 to rotate together. The sleeve 31 drives the cleaning roller 29 to rotate through the belt 30. This allows the cleaning roller 29 to rotate during the movement of the U-shaped placement frame 6 and the installation of the double-ear fixed beam, so as to clean the double-ear fixed beam placed on the U-shaped placement frame 6, prevent dust from accumulating on its surface, and the cleaning process does not require additional driving force.

[0041] Please see the appendix Figure 4 , 5 In a preferred embodiment, the positioning mechanism includes a gear 25 and a suction cup 17. A support plate 27 is welded to one side of the top of the base 8. A support shaft 26 is horizontally rotatably connected to one side of the support plate 27. The gear 25 is welded to the end of the support shaft 26. A second L-shaped connecting rod 24 is fixedly installed on the side of the telescopic end of the hydraulic telescopic rod 28. A second rack 23 is vertically welded to the bottom end of the second L-shaped connecting rod 24. The support plate 27 provides support for the support shaft 26, and the support shaft 26 provides support for the gear 25.

[0042] Please see the appendix Figure 4 , 5 In a preferred embodiment, the second rack 23 meshes with the gear 25, and the other side of the gear 25 is vertically meshed with the first rack 18. Both the first rack 18 and the second rack 23 pass through the base 8 and are slidably connected to the base 8. The bottom end of the first rack 18 is horizontally welded with a lifting plate 22, and the second rack 23 passes through the lifting plate 22 and is slidably connected to the lifting plate 22.

[0043] Please see the appendix Figure 4 , 5 In a preferred embodiment, 7, multiple suction cups 17 are provided, and the multiple suction cups 17 are uniformly adhered to the bottom of the lifting plate 22 in a rectangular array. Limiting rods 19 are vertically welded to both sides of the top of the lifting plate 22, and both limiting rods 19 penetrate the base 8 and are slidably connected to the base 8. The limiting rods 19 restrict the movement of the lifting plate 22, ensuring that it can only move horizontally and cannot tilt.

[0044] When the hydraulic telescopic rod 28 drives the mounting box 15 to rise, it simultaneously drives the second rack 23 to rise through the second L-shaped connecting rod 24. The second rack 23 drives the gear 25 to rotate, which in turn drives the first rack 18 to fall. The first rack 18 drives the lifting plate 22 to fall. When the second rack 23 and the gear 25 are fully engaged, the multiple suction cups 17 are precisely attached to the ground to fix the position of the device, thereby preventing the device from shifting and affecting the fixing process when installing the double-ear fixed beam. Furthermore, the driving force that drives the double-ear fixed beam to rise is used as the driving force for fixing the position of the device, eliminating the need for multiple drive devices, resulting in stronger mechanism linkage and reduced equipment and power costs.

[0045] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: When the device is moved to the position where the double-ear fixed beam needs to be installed, the double-ear fixed beam is placed horizontally on the two U-shaped placement frames 6. The forward and reverse motors 14 are started to drive the lead screw 2 to rotate, so that the two moving blocks 16 move in opposite directions on the lead screw 2. Then, the L-shaped moving plate 11 is driven to move in opposite directions through the first L-shaped connecting rod 13 and the C-shaped connecting rod 12. The L-shaped moving plate 11 drives the U-shaped placement frames 6 to move in opposite directions until the two U-shaped placement frames 6 move to the ends of the double-ear fixed beam. At this time, the supporting force on the double-ear fixed beam is more balanced and stable.

[0046] After the position of the U-shaped placement bracket 6 is adjusted, align the plum blossom groove of the fixing bolt with the plum blossom head 5 and place it. The magnetic plum blossom head 5 will attract the fixing bolt to the plum blossom head 5 and prevent it from falling off.

[0047] When the hydraulic telescopic rod 28 is activated, the mounting box 15 is raised, which in turn raises the double-ear fixed beam on the U-shaped placement frame 6. This eliminates the need for a crane to lift the double-ear fixed beam, preventing swaying during the raising and installation process and facilitating installation. Simultaneously, the hydraulic telescopic rod 28 drives the second rack 23 to rise via the second L-shaped connecting rod 24. The second rack 23 drives the gear 25 to rotate, which in turn lowers the first rack 18. The first rack 18 then lowers the lifting plate 22. Once the second rack 23 and the gear 25 are engaged, multiple suction cups 17 adhere to the ground and fix the device in place, preventing displacement of the device during the installation of the double-ear fixed beam and ensuring proper fixation. Furthermore, the driving force that raises the double-ear fixed beam serves as the driving force for fixing the device, eliminating the need for multiple drive devices, resulting in stronger mechanism linkage and reduced equipment and power costs.

[0048] When the double-ear fixing beam rises to the installation position, the forward and reverse motor 14 is restarted. Similarly, the L-shaped moving plate 11 moves in the opposite direction, which in turn moves the screw 7 in the opposite direction. As the screw 7 moves, because it is threadedly connected to the fixing plate 10, it rotates while moving, causing the sprite head 5 at the front end of the screw 7 to move in the opposite direction. This causes the fixing bolts placed on the sprite head 5 to rotate while moving, thus screwing them into the installation position until the double ears of the double-ear fixing beam are fixed in place. This completes the installation and fixing of the double-ear fixing beam without manual operation, saving time and effort. This device is time-saving and labor-saving, avoiding the need for workers to climb to heights and ensuring worker safety. It uses the same drive mechanism to complete the position adjustment of the U-shaped placement frame 6 and the fixing of the bolts, making the device simpler. At the same time, when the screw 7 moves, since the screw 7 and the sleeve 31 are also connected by threads, the screw 7 drives the sleeve 31 to rotate together. The sleeve 31 drives the cleaning roller 29 to rotate through the belt 30. This allows the cleaning roller 29 to rotate during the movement of the U-shaped placement frame 6 and during the installation of the double-ear fixed beam to clean the double-ear fixed beam placed on the U-shaped placement frame 6, preventing dust accumulation on its surface. Moreover, the cleaning process does not require additional driving force.
