[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1 to 10 , the present invention provides a technical solution:

[0037] A reversible unloading material box for a monorail crane, such as Figures 1 to 3 As shown, it includes a box body 2, and both sides of the box body 2 are fixedly connected with a lifting mechanism 1, and the lifting mechanism 1 includes a lifting plate 101, a butterfly pressure plate 102, a lifting ring 103, a handle 104, a pin assembly 105, a spring tensioning pin 106, a lock 107 and a latch 108. The lifting ring 103 is clamped and movably connected between the lower block 1025. The pin assembly 105 passes through the lower pin hole 1026. One end of the handle 104 is movably inserted into the sleeve 1021 and the connecting hole 1012. The lock 107 is movably located between the upper block 1027. The spring tensioning pin 106 passes through the upper pin hole 1028 and the lock 107. The latch 108 is inserted into the socket 1022. The above-mentioned lifting mechanism 1 can overcome the shortcomings of the existing technology and provide a device with both safety protection and flexibility. Its structure is simple and efficient, and can solve the defects and shortcomings of existing material transport devices.

[0038] like Figure 4 As shown, the lifting plate 101 is fixedly connected to the side of the box body 2, and a pin 1011 is fixedly connected to the side of the lifting plate 101 away from the box body 2, and connection holes 1012 are opened on both sides above the pin 1011.

[0039] like Figure 5 and Figure 6 As shown, a pin connection hole 1024 is provided in the center of the side of the butterfly pressure plate 102, and sleeves 1021 are fixedly connected to both ends of the side of the butterfly pressure plate 102. Lower blocks 1025 are fixedly connected to the side of the butterfly pressure plate 102 on both sides of the pin connection hole 1024, and lower pin holes 1026 are defined within each lower block 1025. Above the pin connection hole 1024, an upper block 1027 is fixedly connected to the side of the butterfly pressure plate 102, and an upper pin hole 1028 is defined within the upper block 1027. The pin 1011 is inserted into the pin connection hole 1024 to flexibly connect the lifting plate 101 to the butterfly pressure plate 102. An insertion hole 1022 is defined on the outer side of the sleeve 1021, away from the pin connection hole 1024, and a pin slot 1023 is defined on the outer side of the sleeve 1021, opposite the insertion hole 1022.

[0040] like Figure 7 and Figure 8 As shown, the handle 104 includes an upper plate 1041, a shaft 1042, a handle pin 1043, a rib 1044, and a baffle 1045, with one end of the upper plate 1041 fixedly connected to the shaft 1042. The rib 1044 and the baffle 1045 are both fixedly connected to the outer side of the upper plate 1041, and the handle pin 1043 is fixedly connected to the outer side of the shaft 1042. Turning the handle 104 can drive the handle pin 1043 forward or backward. The shaft 1042 of the handle 104 is inserted and movably connected between the sleeve 1021 and the connecting hole 1012, and the handle pin 1043 is located and movably located in the pin groove 1023. The latch 108 passes through the rib 1044 and the baffle 1045 and is inserted into the interior of the insertion hole 1022. The latch 108 can prevent the shaft 1042 of the handle 104 from rotating. One end of the shaft rod 1042 away from the upper plate 1041 is fixedly connected with a protrusion, which reduces the resistance of the shaft rod 1042 to advance.

[0041] like Figure 3 and Figure 4 As shown, the pin connection hole 1024 comprises a circular groove and a U-shaped groove, with the U-shaped groove located at the lower end of the circular groove and communicating with it. A circular anti-slip piece is fixedly connected to the end of the pin 1011 away from the lifting plate 101. The diameter of the circular anti-slip piece is smaller than the diameter of the circular groove and larger than the width of the U-shaped groove. The arrangement of the circular groove and the U-shaped groove facilitates the insertion of the pin 1011.

[0042] like Figure 9 and Figure 10As shown, the lifting ring 103 includes a lifting ear 1031 and a lifting block 1032 fixedly connected to both sides of the lower end of the lifting ear 1031. The outer side of the lifting block 1032 is provided with a connecting pin hole 1033. The lifting block 1032 is clamped between the lower block 1025. The pin assembly 105 passes through the lower pin hole 1026 and the connecting pin hole 1033 to movably connect the lifting block 1032 and the lower block 1025. The lifting block 1032 is used to connect the butterfly pressure plate 102. The pin assembly 105 includes a pin rod 1051, a blocking piece 1052 fixed to one end of the pin rod 1051, and a diaphragm 1053 sleeved on the other end of the pin rod 1051. The pin rod 1051 passes through the connecting pin hole 1033 and the lower pin hole 1026 on the lifting block 1032. A stopper 1052 and a diaphragm 1053 are located on either side of the lower block 1025. An elastic pin 1054 is inserted into the end of the pin 1051 near the diaphragm 1053. The stopper 1052 and the elastic pin 1054 prevent the pin 1051 from falling off. A notch is provided in the middle of the outer side of the lifting lug 1031. The notch is used to pass a lifting rope.

[0043] Working principle: The monorail crane uses a reversible unloading material box. When in use, first, insert the pin 1011 on the lifting plate 101 into the pin connection hole 1024 of the butterfly pressure plate 102. During the insertion process, first insert the pin 1011 from the circular groove of the pin connection hole 1024 and then move it into the U-shaped groove.

[0044] Then, the upper plate 1041 of the handle 104 is rotated to a horizontal position, and the latch 108 is inserted through the rib 1044 and the baffle 1045 and into the insertion hole 1022. The rib 1044 and the baffle 1045 can define the position of the latch 108. At this time, the shaft 1042 passes through the sleeve 1021 and is screwed into the connecting hole 1012 of the lifting plate 101, thereby restricting the butterfly pressure plate 102 and the lifting plate 101 from rotating relative to each other.

[0045] Subsequently, the lock buckle 107 is placed between the two upper stoppers 1027 , and the spring tensioning pin 106 is inserted into the upper pin hole 1028 and the lock buckle 107 , thereby confining the lock buckle 107 between the two upper stoppers 1027 .

[0046] Next, the lifting block 1032 of the lifting ring 103 is inserted between the corresponding lower stoppers 1025, and the pin 1051 of the pin assembly 105 is inserted into the lower pin hole 1026 and the connecting pin hole 1033, with one end extending out. The diaphragm 1053 is placed on the extended end of the pin 1051 and the elastic pin 1054 is inserted, thereby connecting the lifting ring 103 and the butterfly pressure plate 102 together.

[0047] After the lifting ring 103 is installed, the lifting rope can be passed through the notch on the lifting ear 1031 of the lifting ring 103 to start lifting.

[0048] When the box 2 is lifted to a certain position by the lifting rope and needs to be turned over, it is only necessary to pull out the latch 108 and then rotate the upper plates 1041 of the two handles 104 counterclockwise by 90 degrees, so that the handle pin 1043 moves from one end of the pin slot 1023 to the other end. At this time, the shaft 1042 is disengaged from the connecting hole 1012, and the butterfly pressure plate 102 and the lifting plate 101 can rotate relative to each other.

[0049] When the butterfly pressure plate 102 and the lifting plate 101 can rotate relative to each other, the staff only needs to apply force to the box body 2 to push the box body 2 and the lifting plate 101 to flip over. During the flipping process, the lock buckle 107 can resist the pin shaft 1011 to restrict it, preventing the pin shaft 1011 from falling off from the pin shaft connecting hole 1024.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
