[0030] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.
[0031] Specific embodiments of the present invention are described below with reference to the accompanying drawings.
[0032] Example 1
[0033] like Figures 1-6 As shown, a trailer bridge assembly fixture includes an open box 1. Roller brackets are installed at the four corners of the bottom surface of the open box 1, and each roller bracket is equipped with a roller 2. The rollers 2 increase the ease of movement of the entire assembly. A pair of symmetrical bidirectional screws 3 are installed inside the open box 1. The left end of each bidirectional screw 3 is rotatably connected to the left inner wall of the open box 1, and the right end of each bidirectional screw 3 penetrates the right side of the open box 1 and is fixedly fitted with a transmission pulley 13. A transmission assembly is provided between the two transmission pulleys 13 and the open box 1.
[0034] A lifting plate 6 is provided above the open box 1. A pair of symmetrical side plates 8 are fixed on the top surface of the lifting plate 6. Each side plate 8 is provided with a threaded rod 12. Each threaded rod 12 passes through the corresponding side plate 8 and is threadedly connected to the side plate 8. A pair of symmetrical adjusting plates 21 are provided between the two side plates 8. One end of each threaded rod 12 is rotatably connected to the corresponding adjusting plate 21. The other end of each threaded rod 12 is fixed with an adjusting handle 11. Fixed plates 7 are provided on both sides of each side plate 8. Each fixed plate 7 is fixedly connected to the top surface of the lifting plate 6. A fixing rod 16 is fixed between two adjacent fixed plates 7. Two sliding cylinders 15 are slidably sleeved on each fixing rod 16. A connecting plate 31 is fixed between two adjacent sliding cylinders 15. An adjusting assembly is provided between the two connecting plates 31 and the lifting plate 6.
[0035] Each bidirectional screw 3 has two threaded cylinders 4 threadedly fitted on the part inside the open box 1. The top of each threaded cylinder 4 is movably hinged to a hinge rod 5, and the top of each hinge rod 5 is movably hinged to the bottom surface of the lifting plate 6.
[0036] The transmission assembly includes a second motor 23 and a belt 22. The second motor 23 is mounted on the inner bottom surface of the open box 1. The model of the second motor 23 is VYF-02. A coupling 25 is fixed on the power output end of the second motor 23. The right end of the coupling 25 passes through the right side of the open box 1 and is fixed with a rotating pulley 24. The two ends of the belt 22 are respectively sleeved on two transmission pulleys 13. The rotating pulley 24 is located inside the belt 22, and the diameter of the rotating pulley 24 is larger than the diameter of the two transmission pulleys 13.
[0037] In practical use, the lifting plate 6 can be adjusted according to the work habits and needs of different workers. The second motor 23 is started, and under the power output of the second motor 23, the connecting shaft 25 and the rotating pulley 24 are driven to rotate synchronously, which in turn drives the belt 22 for transmission. Under the transmission of the belt 22, the two transmission pulleys 13 are driven to rotate synchronously, which in turn drives each bidirectional screw 3 to rotate along the open box 1. At the same time, under the reaction force of the screw, the two threaded cylinders 4 on each bidirectional screw 3 are driven to move synchronously relative to each other and in opposite directions. At the same time, under the hinge operation, each hinge rod 5 is driven to move and hinge along the corresponding threaded cylinder 4 and one end of the bottom surface of the lifting plate 6, which drives the lifting plate 6 to rise and fall. This facilitates the adjustment of the adjustment components, side plates 8, fixed plates 7, etc., and not only makes it convenient for different workers to adjust the lifting plate 6 according to their work needs and habits, but also makes the operation simple.
[0038] Example 2
[0039] like Figures 1-6 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that:
[0040] The adjustment assembly includes a first motor 18, which is installed in the middle of the lifting plate 6. The first motor 18 is a YB3 model. A rotating shaft 17 is fixed on the power output end of the first motor 18. A meshing gear 27 is fixed on the top of the rotating shaft 17. Both sides of the meshing gear 27 are meshed with rack plates 26. The opposite ends of the two rack plates 26 are fixed to the corresponding connecting plates 31. Each connecting plate 31 has a rectangular through hole. The two rectangular through holes are staggered, and each rectangular through hole cooperates with the corresponding rack plate 26.
[0041] In practical use, when assembling trailer bridges, the spacing between adjacent trailer bridges is adjusted according to the different assembly distances. The first motor 18 is started, and under the power output of the first motor 18, the rotating shaft 17 and the meshing gear 27 rotate synchronously. At the same time, under the meshing action, the two rack plates 26 move relative to each other along the meshing gear 27, thereby driving the two connecting plates 31 to move relative to each other. This causes each rack plate 26 to engage with the corresponding rectangular through hole, and at the same time, each slide cylinder 15 slides along the corresponding fixed rod 16, thereby driving the two pairs of fixed blocks 19 to move relative to each other, thereby driving the two L-shaped plates 14 to move relative to each other. The two trailer bridges to be assembled are placed on the two L-shaped plates 14 respectively, so that the two trailer bridges to be installed are symmetrically arranged, which facilitates the subsequent assembly operation. It not only makes it convenient to flexibly adjust according to the assembly distance requirements of the trailer bridges, but also makes the operation simple and easy to promote.
[0042] Example 3
[0043] like Figures 1-6 As shown, while all other parts are the same as in Example 2, the difference between this example and Example 2 is that:
[0044] Each threaded rod 12 has a pair of symmetrical sliding rods 9 on both sides. Each sliding rod 9 passes through the corresponding side plate 8 and is slidably connected to the side plate 8. One end of each sliding rod 9 is fixedly connected to one side of the corresponding adjusting plate 21, and the other end of each sliding rod 9 is fixedly provided with a limiting block 10. Each sliding rod 9 is fitted with a spring 20, and each spring 20 is located between the corresponding side plate 8 and the corresponding adjusting plate 21. In actual use, when it is necessary to clamp and fix the trailer bridge, by rotating the adjusting handle 11, the threaded rod 12 is driven to rotate along the side plate 8, thereby pushing the adjusting plate 21 to move. This facilitates the adjusting plate 21 to cooperate with the L-shaped plate 14 to clamp and fix the trailer bridge. At the same time, when the adjusting plate 21 moves, it simultaneously drives the sliding rod 9 to slide along the side plate 8, thereby driving the limiting block 10 to move, causing the spring 20 to extend and retract, which helps to increase the stability of clamping the trailer bridge.
[0045] Example 4
[0046] As Figures 1-6 shown, in the case of other parts are the same as example 3, the embodiment is different from example 3 in that:
[0047] The top end of each sliding cylinder 15 is fixed with a fixed block 19, the top end of adjacent two fixed blocks 19 is fixed with an L-shaped plate 14, each L-shaped plate 14 is placed with a trailer bridge, a plurality of installation plates 30 are evenly arranged between adjacent two trailer bridges, the bottom surface of each installation plate 30 is fixed with an installation block 28, and each installation block 28 and the corresponding trailer bridge are connected through a plurality of installation bolts 29. In specific use, when adjacent two trailer bridges need to be connected, a plurality of installation plates 30 are placed above the two trailer bridges, since the bottom surface of each installation plate 30 is fixed with an installation block 28, and each installation block 28 and the corresponding trailer bridge are connected through a plurality of installation bolts 29, the trailer bridge is not only convenient to assemble, but also simple to operate.
[0048] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application, and are not intended to limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
