[0030] The drawings are only for illustrative purposes and cannot be understood as a limitation on the patent; in order to better illustrate the embodiment, some components in the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. DETAILED DESCRIPTION

[0031] The technical scheme in the embodiment of the utility model will be clearly and completely described below in combination with the drawings in the embodiment of the utility model.

[0032] As Figures 1 to 7 shown, the embodiment provides a portable transfer device for small-batch profiles of a unit, which comprises a bottom plate 11 with universal casters, and two support frames 12 are respectively installed on the front and rear positions on the bottom plate 11. The support frame 12 is a reversed V-shaped structure, an axle hole is formed in the upper end of the support frame 12, and a main shaft 13 extending in the front and rear directions is installed in the axle hole.

[0033] The two ends of the main shaft 13 are respectively provided with a grabbing mechanism 10, and the two grabbing mechanisms 10 are located at the same horizontal height. The front and rear grabbing mechanisms 10 can simultaneously grab multiple profiles, and the number of profiles to be transported is equal to the number of profiles to be grabbed, thereby saving the resource of a crane.

[0034] In the embodiment, a connecting arm 14 is further rotationally connected to the two sides of the bottom plate 11, a push rod 15 is arranged between the two connecting arms 14, the two ends of the push rod 15 extend out of the connecting arms 14 and are provided with a handle 16. Meanwhile, a recess 17 is formed in the top of each support frame, and when the push rod 15 approaches one of the support frames, it gradually falls into the recess 17. When the transfer device is pushed to move, the push rod 15 and the recess 17 are used for reversing, and the device can be moved on the left and right sides, so that the transfer device can be avoided to turn around, thereby solving the problem that it is inconvenient to change the direction of long profiles during transportation in a workshop.

[0035] In the embodiment, the grabbing mechanism comprises a boom 1, and the upper end of the boom is a lifting hole for connecting with the main shaft 13. The lower end of the boom 1 is connected with a horizontal rod 2 extending in the front and rear directions, and the boom 1 is connected to the middle position of the horizontal rod 2.

[0036] An even number of connecting rods 3 are rotatably connected to the horizontal rod 2, with each two connecting rods 3 forming a group to form a scissor-fork structure; the lower ends of the connecting rods 3 are rotatably connected to grab hooks 4, and the two grab hooks 4 in each group are symmetrical arc structures, and the two grab hooks 4 in the same group are cross-arranged.

[0037] The lower ends of the grab hooks on one side are both fixed to the first connecting block 5, and the lower ends of the grab hooks on the other side are both fixed to the second connecting block 6. A crossbar assembly is provided between the first connecting block 5 and the second connecting block 6. The crossbar assembly includes a plurality of crossbars 7 arranged in a front-to-back direction. The crossbars 7 extend in a left-to-right direction and slide vertically through the first connecting block 5 and the second connecting block 6.

[0038] The first connecting block 5 and the second connecting block 6 are provided with perforations at positions corresponding to the cross bar 7. In order to ensure smooth sliding between the cross bar 7 and the first and second connecting blocks, the inner diameter of the perforations should be 2-3 mm larger than the outer diameter of the cross bar 7.

[0039] In order to prevent the cross bar 7 from falling off from the first connecting block 5 and the second connecting block 6 , stoppers 8 are fixedly provided at both ends of the cross bar 7 , and the stoppers 8 are larger than the through holes.

[0040] In this embodiment, the main shaft 13 is a stepped shaft structure, and has a third shaft section 133 , a second shaft section 132 and a first shaft section 131 in sequence from both ends toward the center.

[0041] The first shaft segment 311 is connected to the support frame 12. The second shaft segment 132 is fitted with a retaining ring. The third shaft segment 133 is connected to the upper end of the boom 1, with a bearing installed between the lifting hole and the third shaft segment 133. An end cap 134 is provided at the end of the third shaft segment 133. The end cap 134 cooperates with the retaining ring to secure the boom 1 axially to the third shaft segment 133.

[0042] The working principle of this utility model is as follows:

[0043] Before use, manually separate the left and right hooks 4 of the two grabbing mechanisms 10. As the hooks 4 separate, the first connecting block 5 and the second connecting block 6 separate toward the ends along the crossbar 7, while the crossbar 7 moves upward. When the profile is placed between the two hooks, the crossbar 7 descends due to gravity, and the connecting rod 3 and hooks 4 converge inward under the scissor action. Gravity pulls the hooks 4 closer and closer, holding the profile tightly.

[0044] Then, the base plate 11 is manually pushed by the handle 16 to move until it reaches a predetermined position.
