[0051] Preferably, in an embodiment, the U-shaped support frame 11 is provided with a stop plate 113, which is used to abut against the flange fixing surface 320 at the lower end of the hopper neck 300. That is, when the support frame 10 abuts against the hopper neck 300, the stop plate 113 abuts against the flange fixing surface 320, thereby further ensuring the reliability of the abutment between the support frame 10 and the hopper neck 300. That is, in an embodiment, the support frame 10 locks the hopper neck 300 by means of the U-shaped support frame 11 combined with the movable rod 12, and a reliable force structure is achieved by abutting the bottom of the stop plate 113 against the flange fixing surface 320. Such a structure can cope with more complex installation conditions, and the overall structure is light, convenient, and reliable in force.

[0052] Specifically, in an embodiment, the stop plate 113 is provided with four, and the four stop plates 113 are distributed in a rectangular shape as a whole, so that the support frame 10 can abut against the flange fixing surface 320 more stably.

[0053] Preferably, in an embodiment, the hanging mechanism 30 includes a hanging plate 31 and a locking member 32, and the hanging plate 31 is connected with the lifting rope 21 of the driving mechanism 20. The locking member 32 is detachably connected with the hanging plate 31, and the locking member 32 is used to connect and fix the hanging plate 31 with the bottom plate 210. That is, the hanging mechanism 30 and the discharger 200 are specifically detachably connected through the locking member 32, when the discharger 200 needs to be disassembled, the hanging plate 31 and the bottom plate 210 are fixed to each other through the locking member 32, and then the hanging plate 31 is lifted through the lifting rope 21, so that the discharger 200 is lifted synchronously. By installing the hanging plate 31 at the bottom plate 210, the lifting process is more stable.

[0054] Specifically, in an embodiment, the locking member 32 is a bolt and a nut.

[0055] Preferably, in an embodiment, one end of the hanging plate 31 is provided with an open slot 311, and the locking member 32 is correspondingly arranged at the open slot 311.

The driving assembly 23 is arranged on the support frame 10 and connected with the rotating shaft 22, and the driving assembly 23 is used to drive the rotating shaft 22 to rotate. The driving assembly 23 provides driving force to drive the rotating shaft 22 to rotate, so as to correspondingly wind or release the hanging rope 21, thereby driving the hanging mechanism 30 to rise or fall, so as to realize the installation or disassembly of the discharger 200.

[0057] Specifically, in an embodiment, the hanging rope 21 is a steel hanging rope, which can better guarantee the structural strength.

[0058] Preferably, in an embodiment, the rotating shaft 22 is provided with two rotating shafts 22, which are arranged at intervals along the radial direction of the rotating shaft 22. Along the axial direction of the rotating shaft 22, the two ends of each rotating shaft 22 are wound with the hanging rope 21, and the lower end of each hanging rope 22 is provided with the hanging mechanism 30. That is to say, the discharger dismounting tool 100 is provided with four hanging mechanisms 30, so that when the discharger 200 is dismounted, the four hanging mechanisms 30 can be fixed at the four corners of the discharger 200, which better guarantees the force balance of the discharger 200 and better guarantees the safety.

[0059] Specifically, in an embodiment, the U-shaped support frame 11 is provided with a rotating shaft mounting plate 115 outside the side frame 114, and the rotating shaft 22 is rotatably arranged on the rotating shaft mounting plate 115, which better guarantees the reliability of the installation of the rotating shaft 22.

That is to say, in this embodiment, the driving assembly 23 is a manual driving mechanism, which can drive the gear box 231 to operate by rotating the hand wheel 233, so as to drive the rotating shaft 22 to rotate through the output gear of the gear box 231, and then drive the discharger 200 to rise and fall. Through this structure, the overall structure is more light and simple, and at the same time, the driving mechanism 20 does not need to rely on external energy, which saves the installation of the cable, further reduces the installation difficulty, and makes the discharger dismounting tool 100 not limited by the installation environment.

[0061] Specifically, in an embodiment, the bottom frame 116 of the U-shaped support frame 11 is provided with a gear box mounting plate 117, and the box body of the gear box 231 is arranged on the gear box mounting plate 117.

[0062] Specifically, in an embodiment, the gear box 231 is provided with two output gears, one of which is connected to one of the rotating shafts 22 through one of the chains 232, and the other of which is connected to the other rotating shaft 22 through the other chain 232.

[0064] The discharger dismounting tool 100 fully utilizes the commonality that the position, size and shape of the neck part of the hopper and the flange fixing surface are basically the same, designs to use a U-shaped support frame combined with a movable rod to lock the neck part of the hopper and abut against the bottom flange fixing surface to realize a reliable force structure, and copes with relatively complex installation conditions, and has the advantages of being light, convenient, reliable in force bearing and the like. And the use of steel lifting rope winding and lifting can adapt to application occasions with large change in loading and unloading height. The use of a speed reduction device, such as a chain, a gear and a hand wheel combination, ensures that the operation is easy and stable. The mass of the discharger dismounting tool 100 is not more than 10 kg, and it is convenient to carry.
