As shown in fig. 1, the utility model provides a tower crane hopper, which comprises a hopper cylinder 1 and a movable base, wherein the hopper cylinder 1 is detachably connected with the movable base, the hopper cylinder 1 is of a hollow cube structure without a cover and a bottom, and a lifting lug 7 is arranged at the top of the hopper cylinder 1; the hopper is characterized in that side plates 2 are arranged on two opposite side surfaces of the hopper cylinder body 1, sliding grooves 3 are formed in two ends of each side plate, sliding grooves 3 on the same side of each side plate 2 form a guide rail for sliding of a movable clamping piece 4, the movable clamping pieces 4 are lapped on the guide rails, positioning blocks 5 are arranged at two ends of each movable clamping piece 4, each movable clamping piece 4 is made of round steel, threads are formed in two ends of each round steel, and the positioning blocks 5 are in threaded connection with two ends of each round steel. For fixing the position of the movable clip 4 and preventing the movable clip 4 from moving axially;

the movable base comprises a bottom plate 8, and a movable clamping piece fixing device is arranged at the bottom edge of the bottom plate 8 and used for clamping the movable clamping piece 4 to complete the assembly of the hopper barrel 1 and the movable base; the bottom of the bottom plate 8 is further provided with four groups of moving devices 9, and in this embodiment, the moving devices 9 are universal wheels; one side of the bottom plate 8 is provided with a pull ring 12, the pull ring 12 is provided with a pull rod 13, and in this embodiment, the pull ring 12 is hinged with the pull rod 13.

One side of the hopper cylinder 1 is provided with a pull rod fixing device 6, in this embodiment, the pull rod fixing device 6 is an L-shaped buckle, the position of the L-shaped buckle and the pull rod 13 are located on the same axis, when the hopper cylinder 1 and the movable base are assembled, as shown in fig. 2, the pull rod 13 is rotated along the pull ring 12 to be almost perpendicular to the ground, and then the pull rod 13 is clamped into the L-shaped buckle.

As shown in fig. 3, the chute 3 is of an L-like structure, in order to ensure that the positioning block 5 fixes the position of the movable clamping piece 4 and prevent the movable clamping piece 4 from axially moving, in this embodiment, the diameter of the positioning block 5 is larger than the width of the chute 3, that is, the position of the positioning block 5 is always located at the outer side of the side plates 2, when the round steel needs to be fixed, the positioning block 5 is screwed with the threads at the end parts of the round steel, so that the positioning block 5 is tightly attached to the side plates 2, when the position of the round steel does not need to be fixed, the positioning block 5 is slightly loosened, the positioning blocks at the two ends of the round steel can prevent the round steel from axially moving, and the axial movement mainly refers to relatively larger axial movement, so that the round steel is separated from the chute 3 at the same side of the two side plates 2, and forms a guide rail for sliding of the movable clamping piece 4.
