[0016] In order to allow those skilled in the art to better understand the present invention, the following clearly and completely describes the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, but it is clear that the described embodiments are only some embodiments of the present invention and do not represent all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in the present invention without any creative work should fall within the scope of protection of the present invention.
[0017] Furthermore, if there is no conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0018] Note that like symbols and letters represent like items in subsequent figures, so once an item is defined in one figure, it need not be further defined and interpreted in subsequent figures.
[0019] (Example) 1 to 3, the present invention proposes a vertical shaft portal frame lifting device, which includes a beam 1, support frames 101 installed on both sides of the bottom of the beam 1, bottom beams 103 connected to the bottoms of both support frames 10, reinforcing structures 2 installed on both bottom beams 103, reinforcing structures 2 including connecting members connected to the bottom beams 103, support beams 204 connected to the connecting members, and second foot brake universal wheels 205 installed at the bottom of the support beams 204. The reinforcing structure 2 forms multi-point support through the support beams 204 and the bottom beams 103, and the support area is larger than that of traditional designs. Combined with the locking function of the second foot brake universal wheels 205, the reinforcing structure 2 can reduce lateral sway during the lifting process and improve operational safety.
[0020] The connecting member further includes a support block 201 fixedly connected to the side of the bottom beam 103, with a support frame 202 disposed on top of the support block 201, and the support frame 202 inserted into and connected to the outer surface of the support beam 204. A second hand screw 203 passing through the support frame 202 and the support beam 204 in sequence is threadedly connected to the support block 201. The mutual engagement of the support block 201, the support frame 202, and the second hand screw 203 can connect the bottom beam 103 welded to the support frame 101 and the support block 201 with the support beam 204.
[0021] Furthermore, a position limiting ring 206 is provided on the outer surface of the second hand screw 203, and the position limiting ring 206 contacts the top of the support frame 202. The position limiting ring 206 can function as a stopper when the second hand screw 203 is tightened downwards, to ensure that the second hand screw 203 is in a predetermined position when tightened.
[0022] After loosening the second hand screw 203, the support beam 204 can be rotated parallel to the bottom beam 103 around the second hand screw 203, i.e., as shown in FIG. 4, making the overall structure more compact and easier to transport when not in use.
[0023] Furthermore, a first foot brake universal wheel 104 is connected to both sides of the bottom of the bottom beam 103. The bottom of the first foot brake universal wheel 104 and the bottom of the second foot brake universal wheel 205 are flush with each other.
[0024] Furthermore, a plurality of first hand screws 105 are threadedly connected to the bottom beam 103, and spacers 106 are provided at the bottom ends of the first hand screws 105. During lifting, by rotating the first hand screws 105, the spacers 106 can be lowered until they contact the support surface, thereby increasing the overall stability. The spacers 106 are welded to the bottom ends of the first hand screws 105.
[0025] Furthermore, a connecting holder 102 is welded to the side of the top of the support frame 101, and the connecting holder 102 is connected to the bottom of the beam 1 via a bolt.
[0026] Furthermore, a slide table 107 provided with a hoist 108 is slidably connected to the beam 1. The hoist 108 is used to lift an article, and the slide table 107 is horizontally movable along the longitudinal direction of the beam 1.
[0027] Furthermore, two partition plates 109 are provided on both the front and back of the beam 1, and the partition plates 109 are welded to the beam 1, and a buffer material is provided on the partition plates 109. The buffer material includes a connecting rod 3 inserted and connected to the partition plate 109, and a pad 301 is fixedly connected to one end of the connecting rod 3 adjacent to the slide table 107, and a stop ring 302 and a nut 304 are provided on the outer surface of the connecting rod 3, and the stop ring 302 and the nut 304 are located on both sides of the partition plate 109, respectively, and a spring 303 is provided on the outer surface of the connecting rod 3, and the spring 303 is located between the pad 301 and the stop ring 302. When the slide table 107 collides with the pad 301 as it moves toward the partition plate 109, the spring 303 is compressed to buffer the impact force, and the pad 301 is made of a metal block welded to the connecting rod 3 and a rubber sleeve wrapped around the outer surface of the metal block.
[0028] Referring to FIG. 1, in order to enhance the stability of the support of the beam 1 by the support frame 101, the first foot brake universal wheel 104, the second foot brake universal wheel 205, the spacer 106 and other parts can be used to enhance the stable bottom support, and the corresponding goods can be lifted by the hoist 108.
