DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 7 , in an embodiment of the present invention, a floor hoist includes a lifting mechanism 6, and the lifting mechanism 6 has two symmetrically arranged outer C-shaped sliding frames 61. Both ends of the two outer C-shaped sliding frames 61 are fixed by outer fixing plates 62; an inner C-shaped sliding frame 63 is slidably connected to the inner side of each outer C-shaped sliding frame 61, and both ends of the two inner C-shaped sliding frames 63 are fixed by inner fixing plates 64; The outer C-shaped sliding frame 61 and the outer fixing plate 62 form an external rectangular frame; the inner C-shaped sliding frame 63 and the inner fixing plate 64 form an internal rectangular frame; the internal rectangular frame can move up and down along the external rectangular frame through a traction mechanism; A sliding frame 69 is provided at the middle position of the internal rectangular frame. The sliding frame 69 is in a "π" shape, and rollers are movably connected to both sides of the sliding frame 69 through rotating shafts, and the rollers are slidably connected to the inner C-shaped sliding frame 63; a cargo lifting assembly 613 is further fixed to the outer side of the sliding frame 69.

[0025] Specifically, the traction mechanism for controlling the lifting of the internal rectangular frame includes first pulleys 68 provided at both ends of the outer C-shaped sliding frame 61. The two first pulleys 68 are传动连接 by a first traction belt 66, and a first motor 67 is further installed in cooperation with the outside of one of the first pulleys 68; The first traction belt 66 is also riveted and fixed to a traction frame 65, and the traction frame 65 is fixed to the inner fixing plate 64 located below the internal rectangular frame.

[0026] By adopting the above technical solution, when in use, first, the relative height of the internal rectangular frame and the external rectangular frame needs to be adjusted according to the site or the height of cargo transportation. During adjustment, the first motor 67 drives one of the first pulleys 68 to rotate. With the cooperation of the other first pulley 68 and the first traction belt 66, the internal rectangular frame can be driven to rise along the external rectangular frame through the traction frame 65, so that the hoist has sufficient height and can be adjusted according to different usage scenarios to meet the needs of cargo transmission.

[0027] In this embodiment, the sliding frame 69 is riveted and fixed to the second traction belt 610, and second pulleys 611 are installed at both ends of the second traction belt 610. The two second pulleys 611 are installed at the middle position of the two ends of the internal rectangular frame through a rotating shaft, and one of the second pulleys 611 is also connected to the second motor 612.

[0028] By adopting the above technical solution, when transporting goods, the goods are placed on the cargo lifting assembly 613, and then the second motor 612 drives a second pulley 611 to rotate, and with the cooperation of another second pulley 611 and the second traction belt 610, the sliding frame 69 is driven to move up and down along the internal rectangular frame, thereby realizing the transportation of the goods.

[0029] In this embodiment, the cargo lifting assembly 613 includes an outer frame 614 fixed on the outside of the sliding frame 69, and two flip arms 615 are provided on the inner side of the outer frame 614; the middle position of the flip arm 615 is movably connected to the outer frame 614 through a rotating shaft; and the inner end of the flip arm 615 is installed on the cylinder rod of the electric push cylinder 617 through a fisheye joint.

[0030] More specifically, one end of the flip arm 615 away from the electric push cylinder 617 is movably connected to a connecting rod 616 via a rotating shaft; the other end of the connecting rod 616 is movably connected to the inner side of the outer frame 614 .

[0031] By adopting the above technical solution, when lifting the goods, the cylinder rod of the electric push cylinder 617 is first contracted, and the flip arm 615 flips around its middle rotating shaft until the flip arm 615 is in a horizontal state. In addition, with the cooperation of the connecting rod 616, the stability of the flip arm 615 in supporting the goods is improved, thereby ensuring that the goods can be transported stably.

[0032] In this embodiment, the lower ends of the two outer C-shaped slides 61 are movably connected to the inner side of the movable frame body 1 through a rotating shaft, and a side support arm 5 is also movably connected to the outer side of the outer C-shaped slide 61; the lower end of the side support arm 5 is fixed to the movable frame body 1 by bolts; the side support arm 5, the outer C-shaped slide 61 and the movable frame body 1 are arranged in a right-angled triangle shape.

[0033] By adopting the above technical solution, when transporting goods, the side arm 5 is unfolded at a certain angle and connected to the mobile frame 1 by bolts, so that the lifting mechanism 6 can be fixed; when not in use, the side arm 5 can be retracted to both sides of the lifting mechanism 6, and the lifting mechanism 6 can be folded onto the mobile frame 1 for movement.

[0034] In this embodiment, a plurality of transmission rollers 4 are arranged in a line in an array on the inner side of the mobile frame 1; a plurality of running wheels 2 are arranged at the bottom of the mobile frame 1, and a traction mechanism 3 is movably connected to one end of the mobile frame 1.

[0035] By adopting the above technical solution, when moving, the cylinder rod of the electric push cylinder 617 is first extended, and the flip arm 615 flips around its middle rotating shaft until the flip arm 615 is in a vertical state. At this time, the contraction of the cargo lifting component 613 is realized. Since a rectangular cavity is provided at one end of the mobile frame 1 connected to the lifting mechanism 6, the size of the cavity is larger than the outer size of the cargo lifting component 613. Therefore, the cargo lifting component 613 is slid to a suitable position, and the lifting mechanism 6 is folded onto the mobile frame 1, so that the cargo lifting component 613 is in the cavity, thereby improving the fitting effect of the lifting mechanism 6 and the mobile frame 1.

[0036] The arrangement of the transport rollers 4 can be used as a roller conveyor to transport goods.

[0037] The working principle is: when transporting goods, the side arm 5 is unfolded at a certain angle and connected to the mobile frame 1 by bolts, so that the lifting mechanism 6 can be fixed; the relative height of the inner rectangular frame and the outer rectangular frame is adjusted according to the site or the height of the goods to be transported. During adjustment, the first motor 67 drives a first pulley 68 to rotate, and the inner rectangular frame can be driven to rise along the outer rectangular frame through the traction frame 65 under the cooperation of another first pulley 68 and the first traction belt 66, so that the hoist has enough height and can be adjusted according to different usage scenarios to meet the needs of cargo transportation.

[0038] When the goods are transported, the cylinder rod of the electric push cylinder 617 contracts, and the flip arm 615 flips around the central rotating shaft until the flip arm 615 is in a horizontal state. In addition, the cooperation of the connecting rod 616 improves the stability of the flip arm 615 in supporting the goods, thereby ensuring that the goods can be transported stably. Then, the goods are placed on the goods lifting assembly 613, and then the second motor 612 drives a second pulley 611 to rotate, and the sliding frame 69 is driven to move up and down along the internal rectangular frame under the cooperation of another second pulley 611 and the second traction belt 610, thereby realizing the transportation of the goods. When not in use, the cylinder rod of the electric push cylinder 617 is first extended, and the flip arm 615 is flipped around its middle rotating shaft until the flip arm 615 is in a vertical state. At this time, the cargo lifting component 613 is retracted. Since a rectangular cavity is provided at one end of the mobile frame 1 connected to the lifting mechanism 6, the size of the cavity is larger than the outer size of the cargo lifting component 613. Therefore, the cargo lifting component 613 is slid to a suitable position, and the lifting mechanism 6 is folded onto the mobile frame 1, so that the cargo lifting component 613 is in the cavity, thereby improving the fitting effect of the lifting mechanism 6 and the mobile frame 1; combined with the walking wheels 2 and the traction mechanism 3 at the bottom, the movement of the equipment is greatly facilitated.
