Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, in particular to a valve seat transport hopper for a crane. Background Art

[0002] A crane refers to a multi-action lifting machinery that vertically lifts and horizontally moves heavy objects within a certain range. It is also called an overhead crane, overhead crane, or hoist.

[0003] In order to facilitate the use of cranes to transport valve seats, valve seat transport hoppers are usually used to collect the valve seats. However, in the existing technology, most valve seat transport hoppers do not have a cover plate on the top. As a result, when a crane is used to transport the valve seat transport hopper on rainy days, rainwater will enter from the top of the valve seat transport hopper and accumulate in the valve seat transport hopper, which can easily cause the valve seat in the valve seat transport hopper to be corroded by rainwater and rust, thereby affecting the normal use of the valve seat. Utility Model Content

[0004] The purpose of the utility model is to provide a valve seat transport hopper for a crane to solve the problems raised in the background technology.

[0008] As a preferred embodiment, the rack is in meshing transmission with the gear.

[0009] As a preferred embodiment, the limiting assembly includes a limiting groove and a limiting block; a limiting groove is formed on one side of the fixing plate away from the valve seat transport hopper body; the limiting block is fixedly arranged on the side of the rack away from the counterweight block.

[0010] As a preferred embodiment, the limiting block is in sliding fit with the limiting groove.

[0011] As a preferred embodiment, the limiting block is of an isosceles trapezoid structure, and the dimension of the limiting block close to the rack is smaller than the dimension of the limiting block away from the rack.

[0012] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0013] For the valve seat transport hopper for the crane, by arranging an opening and closing assembly, during use, first, an appropriate amount of valve seats are placed into the valve seat transport hopper body.

[0037] Working principle

[0038] This crane uses a valve seat transport hopper. When in use, first, place an appropriate amount of valve seats into the valve seat transport hopper body 1. Then, connect the lifting steel bar ring 311 to the crane. By pulling the lifting steel bar ring 311 upward with the crane, the rack 309 drives the counterweight 310 to move upward, causing the limit block 402 to slide upward in the limit groove 401, making the rack 309 engage and drive with the gear 308, causing the gear 308 to rotate through the rotating shaft A, causing the rotating plate A306 to rotate, causing the rotating plate A306 to rotate with the rotating plate B307 through the rotating shaft B, causing the rotating plate B307 to rotate through the limit post block B305, making the limit post block A304 act as a rotating shaft, causing the limit post block B305 to slide in the wedge groove 3022, causing the rotating member 303 to drive the cover body 2 to rotate until the limit post block B305 slides to the intersection of the sliding groove 3021 and the wedge groove 3022. At this time, the limit post block B305 slides downward in the sliding groove 3021 until the top surface of the limit block 402 contacts the inner top wall of the limit groove 401. At this time, the limit post block B305 contacts the inner bottom wall of the sliding groove 3021, realizing the closing of the cover body 2 (as Figure 1 shown), and then the valve seat transport hopper body 1 can be transported;

[0039] After transporting the valve seat transport hopper body 1 to a suitable position, move the valve seat transport hopper body 1 downward until the valve seat transport hopper body 1 contacts the ground. At this time, due to the gravity of the counterweight 310, the rack 309 and itself, the rack 309 drives the counterweight 310 to move downward, causing the limit block 402 to slide downward in the limit groove 401, making the rack 309 engage and drive with the gear 308, causing the gear �08 to rotate in the opposite direction through the rotating shaft A, causing the rotating plate A306 to rotate in the opposite direction, causing the rotating plate A306 to rotate with the rotating plate B307 in the opposite direction through the rotating shaft B, causing the rotating plate B307 to rotate in the opposite direction through the limit post block B305, causing the limit post block B305 to slide upward in the sliding groove 3021, causing the limit post block A304 to slide upward in the sliding groove 3021, causing the rotating member 303 to move upward until the limit post block A304 slides to the inner top wall of the sliding groove 3021. At this time, the limit post block A304 acts as a rotating shaft, causing the limit post block B305 to slide in the opposite direction in the wedge groove 3022, causing the rotating member 303 to drive the cover body 2 to rotate in the opposite direction until the top surface of the limit block 402 contacts the inner bottom wall of the limit groove 401. At this time, the limit post block B305 contacts the inner top wall of the wedge groove 3022, realizing the opening of the cover body 2 (as Figure 2 shown), and then valve seats can be added to the valve seat transport hopper body 1.
