[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] like Figure 1-Figure 3 As shown, a belt conveyor leg rapid lifting mechanism comprises a mounting beam 1, first legs 2 are fixedly mounted at both ends of the mounting beam 1, sleeves 3 are sleeved on the upper ends of the two first legs 2, a connecting rod 4 is arranged between the two sleeves 3, and both ends of the connecting rod 4 are fixedly connected to the sleeves 3; a mounting seat 5 and a support rod 6 are fixedly mounted on the mounting beam 1, a fixed pulley 7 is arranged on the upper end of the support rod 6, a pull rope 9 is wound around the fixed pulley 7, one end of the pull rope 9 is fixedly connected to the connecting rod 4, and a driving mechanism 8 for retracting and releasing the pull rope 9 is arranged on the mounting seat 5; the upper end of the sleeve 3 is fixedly mounted on a support frame 11, a second leg 10 is fixedly mounted on the lower part of the support frame 11 away from the sleeve 3, and a belt conveyor 12 is arranged on the support frame 11; a universal self-locking wheel is fixedly mounted on the lower end of the first leg 2; and a directional wheel is fixedly mounted on the lower end of the second leg 10.

[0022] The driving mechanism 8 includes a support 81 fixedly mounted on the mounting base 5, and the support 81 is a U-shaped groove steel structure. A rope-collecting roller 82 is arranged on the inner side of the support 81 close to the support rod 6, and the core shaft of the rope-collecting roller 82 is installed on the support 81 through a bearing. A driven gear 83 fixedly mounted on the core shaft of the rope-collecting roller 82 is arranged at one end of the rope-collecting roller 82, and a driving gear meshing with the driven gear 83 is arranged on the inner side of the support 81 away from the support rod 6. The core shaft of the driving gear is installed on the support 81 through a bearing, and the core shaft of the driving gear extends out of the support 81 and is fixedly mounted with a crank 85. A self-locking mechanism for preventing the gear from reversing is also arranged on the inner side of the support 81.

[0023] The self-locking mechanism includes a self-locking block 86, on which a rotating shaft is fixed and passed. Both ends of the rotating shaft are respectively mounted on the support 81 through bearings. The self-locking block 86 is in the shape of a triangle. In the natural state, the self-locking block 86 has one corner at the bottom and two corners at the top, and one of the corners at the top is set to bend downward and press on the upper half of the driving gear 84 on the side close to the self-locking block 86.

[0024] Working principle: When in use, by shaking the crank 85, the driving gear rotates and the self-locking block 86 is toggled, the driven gear 83 rotates, so that the rope roller 82 rotates to reel in the pull rope 9, and the pull rope 9 pulls the connecting rod 4 to rise, so that the sleeve 3 rises, and the sleeve 3 and the first leg 2 are extended, so as to adjust the inclination angle of the belt conveyor 12. After adjusting to the required state, under the action of gravity, the connecting rod 4 will have a downward force, so that the pull rope 9 is transmitted, and the rope roller 82 and the driven gear 83 have a reverse rotation force, which is caused by Since the driving gear and the driven gear 83 are meshed, the driving gear is also subjected to a reverse rotation force, and the self-locking block 86 presses on the driving gear to prevent the driving gear from rotating in the reverse direction, thereby realizing self-locking and preventing the sleeve 3 from falling due to gravity; when the sleeve 3 needs to fall, the convex corner of the upper part of the self-locking block 86 away from the driving gear side is pulled to make it disengage from the driving gear, and then the crank 85 is rotated in the reverse direction to realize the falling control of the sleeve 3. After falling to the use height, the self-locking block 86 is released, and the self-locking block 86 presses on the driving gear to achieve locking.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements shall fall within the scope of the utility model to be protected.
