[0023] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 5When the jack is lifted up, the lifting board 3 is lifted up and the support frame 7 is lifted up, and the support frame 7 is lifted up and the support frame 7 is in a state of being rotated. The cam 3 is provided with a plurality of support members 1 and a plurality of support members 2, and the support members 3 are provided with a plurality of support members 1 and a plurality of support members 2 are provided at the support members 3.

[0025] The specific configuration of the clamping mechanism 4 is as follows: Figures 1 to 3 As shown, each set of clamping mechanisms 4 includes a vertically arranged fixing plate 41, which is fixedly connected to the top surface of the bearing platform 3 and spaced apart from the first limit plate 1, and each fixing plate 41 is threadedly connected with a clamping bolt 42 that horizontally passes through the fixing plate 41, and the screw ends of the clamping bolts 42 are facing the first limit plate 1. Specifically, two clamping bolts 42 can be set on each fixing plate 41; and when in use, by rotating the clamping bolts 42, when the screw ends of the clamping bolts 42 are pressed against the box beam, the box beam can be clamped with the cooperation of the first limit plate 1 and the second limit plate 2, thereby facilitating the fixing of the box beam on the bearing platform 3.

[0026] In order to improve the stability of the clamping mechanism 4 when clamping the box beam, Figure 1 and Figure 3 As shown, a movable clamping block 43 is provided between the screw end of the clamping bolt 42 and the first limit plate 1. Specifically, when in use, the clamping block 43 can be pushed by rotating the clamping bolt 42. In this way, when the clamping block 43 is pressed against the box beam, the pressing area between the clamping mechanism 4 and the box beam can be increased, thereby improving the stability of the clamping mechanism 4 when clamping the box beam.

[0027] The specific setting method of the sliding connection between the carrying platform 3 and the bottom frame 7 is as follows: Figure 1 and Figure 3 As shown, two horizontally opposite I-shaped rails 8 are installed on the top surface of the bottom frame 7, and a walking beam 9 arranged parallel to the I-shaped rail 8 is provided above each I-shaped rail 8. Both ends of the walking beam 9 are equipped with walking wheels 10 that are rollingly connected to the I-shaped rail 8, and the supporting platform 3 that is slidingly connected to the bottom frame 7 is installed between the two walking beams 9. In this way, when in use, the walking beam 9 can be moved along the I-shaped rail 8 by pushing the supporting platform 3, so as to drive the supporting platform 3 to move horizontally along the bottom frame 7.

[0028] In order to improve the stability of the carrying platform 3 during horizontal movement, Figure 1 、 Figure 3 and Figure 4 As shown, guide wheel mechanisms 5 are installed at both ends of each walking beam 9, and the guide wheel mechanisms 5 include wheel frames 51 connected to the ends of the walking beams 9. The wheel frames 51 are respectively located above the I-shaped rails 8, and both sides of the wheel frames 51 are rotatably connected to guide wheels 52 located outside the two sides of the I-shaped rails 8. The axial lines of the guide wheels 52 are all vertically set. Specifically, guide wheels 52 are installed at the four corners of each walking beam 9; and when in use, when the carrying platform 3 is in the process of horizontal movement, the guide wheels 52 can move along the I-shaped rails 8 to play a guiding role, thereby improving the stability of the carrying platform 3 in the process of horizontal movement.

[0029] In order to facilitate the movement of the carrying platform 3, and when the carrying platform 3 is moved into place, in order to facilitate the positioning of the carrying platform 3, Figure 1 and Figure 3As shown, a rack 11 parallel to the I-shaped rail 8 is installed on one side of one of the I-shaped rails 8, and one of the guide wheels 52 of a group of guide wheel mechanisms 5 is a gear meshed with the rack 11, and the guide wheel 52 is also transmission-connected to a drive motor 12 installed on the wheel frame 51. Specifically, the drive motor 12 is a servo motor. When in use, after the drive motor 12 is started, it can drive the guide wheel 52, which is a gear, to rotate, and when the gear moves along the rack 11, it can automatically drive the carrying platform 3 to move synchronously, thereby facilitating the movement of the carrying platform 3 and improving the stability of the carrying platform 3 during movement; in addition, after the carrying platform 3 is moved into place, with the cooperation of the gear and the rack 11, it can also facilitate the positioning of the carrying platform 3.

[0030] In order to make the carrying platform 3 automatically stop running after it is in place, Figure 1 As shown, a control box 13 is also installed on the carrying platform 3 that is slidably connected to the bottom frame 7. The control box 13 is electrically connected to the drive motor 12. Specifically, the control box 13 is a PLC controller in the prior art, and is equipped with a touch screen operation panel. When in use, the initial position of the carrying platform 3 that is slidably connected to the bottom frame 7 can be set to the origin position, and then the distance that the carrying platform 3 needs to move can be calculated according to the length of the connecting beam. Then, the distance that the carrying platform 3 needs to move can be input in advance into the control box 13 through the touch screen operation panel. In this way, the control box 13 can accurately adjust the carrying platform 3 to the set position by controlling the number of revolutions of the drive motor 12, so that the carrying platform 3 can automatically stop running after it is in place.

[0031] The specific arrangement of the I-shaped rail 8 on the bottom frame 7 is as follows: Figure 5As shown, both sides of the bottom of each I-shaped rail 8 are fixedly connected to a number of mounting plates 15 equidistantly distributed and horizontally arranged along the length direction of the I-shaped rail 8, and a number of threaded rods 16 equal in number and opposite in position to the mounting plates 15 are fixedly connected to the bottom frame 7 outside the two sides of the I-shaped rail 8. The threaded rods 16 are all vertically arranged, and the top ends of the threaded rods 16 respectively penetrate the mounting plates 15 and are slidably connected to the mounting plates 15. The top ends of the threaded rods 16 penetrate the mounting plates 15 and are threadedly connected to the locking nuts 17. Specifically, when installing the I-shaped rail 8, the mounting plates 15 can be first separated and fixed. 7, and then the locking nuts 17 are installed on the threaded rods 16. Then, when the locking nuts 17 are tightly against the mounting plates 15, the I-shaped rail 8 can be fixed to the bottom frame 7. After removing the locking nuts 17, since the threaded rods 16 and the mounting plates 15 are slidably connected, the I-shaped rail 8 can be removed by lifting the I-shaped rail 8 and separating the mounting plates 15 from the threaded rods 16, thereby facilitating the disassembly and assembly of the I-shaped rail 8 on the bottom frame 7.

[0032] In the process of use, in order to prevent the position of the I-shaped track 8 from shifting, Figure 5 As shown, several groups of anti-deflection mechanisms 6 are installed on the bottom frame 7 outside the two sides of the I-shaped rail 8, which are equidistantly distributed along the length direction of the I-shaped rail 8. Each group of anti-deflection mechanisms 6 includes an L-shaped bracket 61 fixedly connected to the bottom frame 7, and each L-shaped bracket 61 is threaded with an anti-deflection bolt 62 that horizontally passes through the L-shaped bracket 61, and the screw ends of the anti-deflection bolt 62 are respectively in contact with the I-shaped rail 8. In this way, when in use, the anti-deflection bolts 62 on both sides of the I-shaped rail 8 can simultaneously apply a horizontal force to the bottom of the I-shaped rail 8, thereby preventing the position of the I-shaped rail 8 from shifting; in addition, when the position of the I-shaped rail 8 is fixed, the bottom surface of the mounting plate 15 can be set to abut against the L-shaped bracket 61, so that the structure is more stable.

[0033] In order to facilitate the disassembly and assembly of the box beam on the bearing platform 3, Figure 1 and Figure 2 As shown, the outer side of each supporting platform 3 is fixedly connected to a walkway 18 arranged parallel to the supporting platform 3, and the walkway 18 is located at the bottom of the supporting platform 3; when in use, the operator can move along the supporting platform 3 through the walkway 18, which makes it convenient to fix or loosen the box beam on the supporting platform 3, thereby making it convenient to disassemble and assemble the box beam on the supporting platform 3; in addition, the side of the walkway 18 away from the supporting platform 3 is fixedly connected to the guardrail 14 arranged parallel to the walkway 18, and the guardrail 14 can prevent the operator from falling from the walkway 18.
