[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the terms "center", "up", "down", "front", "back", "top", "bottom", "left", "right", "vertical", "horizontal", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] The first clamp 2 and the second clamp 6 have the same structure and adopt the existing scissor-type clamp. After the bagged material is placed between the two clamp arms of the clamp, the two clamp arms clamp the bagged material in the middle by the gravity of the bagged material.

[0024] Working principle: When in use, the truck is parked under the second clamp 6, the electric lifting mechanism 3 is controlled to descend, so that the second clamp 6 descends, and the worker clamps the bagged material with the second clamp 6, and then the second clamp 6 is pulled up by the electric lifting mechanism 3 until it is at the same height as the first clamp 2; at this time, all the first clamps 2 are pulled close to the second clamp 6, and the first clamp 2 farthest from the second clamp 6 is first clamped on both sides of the lifted bagged material, and the electric lifting mechanism 3 is controlled to lower the second clamp 6, and the weight of the bagged material is gradually transferred to the first clamp 2. After the first clamp 2 clamps the bagged material, the second clamp 6 is removed. The first clamp 2 with the bagged material can be pushed along the track to the other end of the transverse slide rail 4 to complete the unloading; then the second clamp 6 continues to clamp the second bag of material and transfers it to each first clamp 2 in sequence from far to near. After all the first clamps 2 are pushed to the other end of the transverse slide rail 4, the workers remove them from the first clamp 2, and then push all the first clamps 2 to one end of the second clamp 6 to start the second round of transportation; the electric lifting mechanism 3 replaces manpower to lift the bagged material, which reduces the labor intensity of the workers. The transverse slide rail 4 can slide on the transverse slide rail 4 through the pulley block 5, replacing manual transportation, thereby improving the efficiency of unloading and transfer.

Both ends of the connecting pipe 103 pass through the slide rail support 701 and are symmetrically integrally formed with inclined surfaces at both ends. One end of the transverse pipe 104 passes through the column 101 and is fixed to the top of the column 101. The other end of the transverse pipe 104 is integrally formed with an inclined surface that matches the end edge of the connecting pipe 103. The inclined surface of the transverse pipe 104 and the inclined surface of the connecting pipe 103 play a limiting role to prevent the connecting pipe from being The connecting pipe 103 and the cross pipe 104 rotate relative to each other; one end of the fixing rod 702 passes through the cross beam 102 from one column 101 and passes through the other column 101. One end of the fixing rod 702 is fixed with a limit cap 703 clamped on one column 101, and the other end of the fixing rod 702 is screwed with a locking nut 704 clamped on the other column 101. The fixing rod 702 presses the cross pipes 104 on both sides toward the middle, and the two oblique contacts between the cross pipe 104 and the connecting pipe 103 are The surfaces match each other, which can prevent the connecting tube 103 and the cross tube 104 from rotating relative to each other, thereby keeping the column 101 and the transverse track 4 vertical, thereby preventing the column 101 from tilting; the fixing rod 702 can be pulled out during transportation to separate the column 101 from the transverse track 4 for easy transportation. When it is needed to be built, it is inserted into the cross beam 102, and the columns 101 on both sides are fixed to the transverse track 4 through the locking nut 704 on the other side, which is convenient for assembly and construction.

The speed-changing wheel group 302 includes an input reel 304, an output reel 305, a bearing seat 306 and a transmission shaft. The bearing seat 306 is fixedly connected to the top surface of the second slide rail 402. The transmission shaft is penetrated on the bearing seat 306. The transmission shafts on both sides of the bearing seat 306 are respectively fixedly sleeved with input The diameter of the input reel 304 is smaller than that of the output reel 305. The electric winch 301 has a large traction force, but a slow lifting speed. Therefore, the lifting speed of the second clamp 6 is increased by the variable speed wheel group 302, thereby improving the efficiency. A guide wheel 303 is fixedly installed on the top surface of the second slide rail 402 and on the other side of the electric winch 301. The electric winch 301 is connected to the input reel 304 of the variable speed wheel group 302 through a steel wire rope. The steel wire rope on the output reel 305 of the variable speed wheel group 302 passes around the guide wheel 303 and is connected to the second clamp 6.

[0027] When in use, the electric winch 301 can be controlled to rotate forward and reverse to control the lifting and lowering of the second clamp 6. A certain length of wire rope is wound in the input reel 304 and the output reel 305 of the variable speed wheel group 302. When the second clamp 6 needs to rise: the electric winch 301 rotates forward to reel in the wire rope, pull the wire rope in the input reel 304 out, drive the input reel 304 and the output reel 305 to rotate together, the output reel 305 rotates, reels in the wire rope, tightens the wire rope on the output reel 305, pulls the wire rope bypassing the guide wheel 303, and thus pulls up the second clamp 6 connected to the other end of the wire rope; when the second clamp 6 needs to be lowered: the electric winch 301 rotates reversely to prevent the wire rope from loosening, and the second clamp 6 pulls the wire rope in the output reel 305 out by its own gravity, and at the same time the input reel 304 also rotates synchronously to reel the wire rope extended by the electric winch 301 into the reel groove of the input reel 304.

The second pull rod 804 transmits the load gravity and its own weight of the second slide rail 402 to the first slide rail 401 through the two fixed columns 801 through the transverse pull rod and the first pull rod 802, so that the second slide rail 402 and the first slide rail 401 can be kept horizontal, and the overall structure is kept stable during operation; when the second slide rail 402 is folded, the connecting sleeve 803 can rotate around the fixed column 801, and the second pull rod 804 rotates horizontally together with the second slide rail 402, so as to realize the folding function and facilitate transportation and storage.
