DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] As Figures 1-5 The utility model provides a beam carrying device for semitrailer manufacturing, including support frame 1, still include:

[0025] Carrying assembly is set up on support frame 1, is used to lift up and transport semitrailer beam;

[0026] Wherein, carrying assembly includes notch 2, and notch 2 is set up in the inside of support frame 1, and the inside of notch 2 is installed with fixed link 3, and the inside of notch 2 is rotatably connected with threaded rod 7, and the outer surface of fixed link 3 is slidably connected with first movable frame 4, and the inside of first movable frame 4 is fixed with first connecting frame 5, and the one side of support frame 1 top is fixed with drive motor 6, and the outside of first connecting frame 5 is hinged with two sets of clamping piece 8, and the top of first connecting frame 5 is slidably connected with movable link 9, and the top of movable link 9 is connected with second connecting frame 10, and the bottom of movable link 9 passes through first connecting frame 5 and is connected with second movable frame 12, and the one side of second movable frame 12 is set with sliding slot 13, and the one side of clamping piece 8 is fixed with connecting piece 14, and the outside of connecting piece 14 is fixed with connecting shaft 15, and the top of first movable frame 4 is installed with fixed plate 16, and the top of fixed plate 16 is connected with winch 17, and the outer surface of movable link 9 is sleeved with return spring 11.

[0027] By operating the winch 17, a tension can be applied to the second connecting frame 10 by controlling the wire rope. This allows the movable rod 9 to move along the inner side of the first connecting frame 5 via the second connecting frame 10, causing it to press against the connecting shaft 15 via the sliding groove 13 through the second movable frame 12. Consequently, the connecting shaft 15 can rotate the connecting piece 14 and the clamping piece 8, causing the two sets of clamping pieces 8 to move below the semi-trailer crossbeam and apply a tension upward to the crossbeam, thus clamping the semi-trailer crossbeam. Furthermore, the cooperation between the first movable frame 4 and the fixed rod 3 prevents swaying and improves the stability during handling.

[0028] like Figure 2 , 3 As shown, the connecting shaft 15 is slidably connected to the slide groove 13, and the inner wall of the slide groove 13 is in contact with the surface of the connecting shaft 15 by compression.

[0029] Through the cooperation between the connecting shaft 15 and the slide 13, when the second movable frame 12 moves downward, a pushing force will be applied to the connecting shaft 15 through the slide 13, causing the two sets of clamping parts 8 to unfold outward for easy unloading. When the second movable frame 12 moves upward, a pulling force will be applied to the connecting shaft 15 through the slide 13, thereby causing the two sets of clamping parts 8 to move inward and clamp the semi-trailer crossbeam.

[0030] like Figure 2 As shown, the reset spring 11 is elastically supported between the second movable frame 12 and the first connecting frame 5.

[0031] The design of the return spring 11 enables the second movable frame 12 to have good elastic return performance. Since the return spring 11 is in a compressed state, it will apply an elastic force to the second movable frame 12, so that when the winch 17 releases the tension on the second connecting frame 10, the second movable frame 12 can be controlled to return to its original position.

[0032] like Figure 2 , 4 As shown, the first movable frame 4 is threadedly connected to the threaded rod 7, and the bottom of the wire rope of the winch 17 is connected to the second connecting frame 10.

[0033] By driving the motor 6, the threaded rod 7 can be rotated. Through the cooperation between the threaded rod 7 and the first movable frame 4, the first movable frame 4 can be moved upward along the outer surface of the fixed rod 3. When the first movable frame 4 moves upward, the clamping part 8 will move upward synchronously through the first connecting frame 5. This makes it easier to adjust the height of the semi-trailer crossbeam and to move the clamping part 8 above the semi-trailer crossbeam.

[0034] like Figure 3 , 5As shown, the bottom end of the clamping piece 8 is provided with a slope, and one side of the clamping piece 8 is in extrusion contact with the semitrailer beam.

[0035] Through the slope provided at the bottom end of the clamping piece 8, when the clamping piece 8 extrudes the bottom of the semitrailer, it can move below the semitrailer beam, facilitating the clamping of the inner side of the semitrailer beam.

[0036] As shown in the drawings, Figure 1 , 2 The bottom of the support frame 1 is provided with four groups of universal wheels.

[0037] Through the universal wheels provided at the bottom of the support frame 1, it is convenient to push the support frame 1 to move, thereby facilitating the transportation of the semitrailer beam.

[0038] Working principle:

[0039] First, through the operation of the driving motor 6, the threaded rod 7 can be controlled to rotate, so that through the cooperation between the threaded rod 7 and the first movable frame 4, the first movable frame 4 can be driven to move upwards along the outer surface of the fixed rod 3, so that it controls the clamping piece 8 to move upwards through the first connecting frame 5. Then the staff can push the support frame 1 to drive the clamping piece 8 to move above the semitrailer beam, and then control the clamping piece 8 to move downwards to the two sides of the semitrailer beam through the driving motor 6, and then through the operation of the winch 17, the steel wire rope can be controlled to exert a pulling force on the second connecting frame 10, so that the movable rod 9 can be driven to move along the inner side of the first connecting frame 5 through the second connecting frame 10, so that the sliding groove 13 can be driven to extrude the connecting shaft 15 through the second movable frame 12. Therefore, the connecting piece 14 and the clamping piece 8 can be driven to rotate through the connecting shaft 15, so that the two groups of clamping pieces 8 move below the semitrailer beam and upwardly exert a pulling force on the beam, thereby clamping the semitrailer beam, facilitating the stable transportation thereof.

[0040] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
