Description

Technical Field

[0001] The invention relates to a loading mechanical equipment in the technical field of coal coke chemical industry, in particular to a track guide frame for a residual coal single bucket elevator. Background Art

[0002] During coking production, a certain amount of excess coal will be brought out during the leveling process of the coke pusher. This excess coal is collected in the excess coal hopper of the coke pusher in advance. When the excess coal hopper is full, the coke pusher puts the excess coal into the excess coal elevator hopper located in the coke oven platform, and the excess coal elevator sends it to the coal tower for recycling. The current excess coal lifting device consists of a hopper, a feeder and a belt. The hopper is provided with a discharge port, and the spiral feeder and the lifting belt are connected to it. When in use, the excess coal collected by the coke pusher is first poured into the elevator hopper, sent to the lifting belt by the spiral feeder, and then sent to the coal tower for recycling by the excess coal elevator. The defect is that since the coking coal has a small fineness (75% of the particles are less than 3mm) and contains about 10% water, it is easy to adhere to the hopper wall. The accumulated thickness over a long period of time directly affects the material discharge, causing the excess coal to overflow, pollute the environment, and waste resources. At this time, the excess coal lifting device needs to be closed and manually shoveled, which destroys the continuity of production; at the same time, the excess coal slides down under the action of gravity, often causing the excess coal in the lifting belt to overflow; the lifting belt needs to be replaced regularly, which affects the release of the excess coal by the coke pusher, thereby affecting the stability and continuity of the coke oven production.

[0003] For this reason, it is urgent to develop a special single-bucket elevator for residual coal, including a fixed track, a single-bucket trolley, a residual coal collecting chute and a lifting device. Summary of the invention

[0004] In order to overcome the defects of the prior art, the technical problem solved by the present invention is to provide a rail guide frame used in conjunction with a residual coal single-bucket elevator. Through its guidance, the residual coal single-bucket trolley can rise to the top to complete the flipping action, thereby achieving the purpose of the residual coal single-bucket trolley transporting all the residual coal to the upper coal hopper. It can be automatically put back to the bottom of the lower coal hopper when it descends, and automatically docked with the lower coal hopper through the flipping spout.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] There are a plurality of fixing plates, which are evenly distributed and welded between the first track guide frame and the second track guide frame at a certain interval.

[0008] The connecting ends of the bottom track frame, the first track guide frame and the second track guide frame are arc transitions, and the angle a between them is 20-30°.

[0009] The bottom movable rail is composed of a blocking wheel, a connecting rod, a rocker arm, a counterweight and a rocker rail, wherein there are two rocker arms, two rocker rails and two guide wheels, the two rocker rails are arranged equidistantly from the bottom track frame, and the upper part is hinged to the bottom track frame through a connecting shaft; one end of the two rocker arms is respectively welded to the outer side of the rocker rail, and the other end is hinged through the connecting rod, and the middle end near the rocker rail is hinged to the bottom track frame through a rotating shaft; the counterweight is assembled on the connecting rod, and the two guide wheels are respectively arranged at the end of the rocker arm near the rocker rail.

[0019] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0020] See Figure 1 to Figure 3 As shown, the present invention relates to a track guide frame for a residual coal single bucket elevator, comprising a first track guide frame 41, a second track guide frame 42, a bottom track frame 43, a bottom movable rail 44, a connecting shaft 447, a rotating shaft 448 and a fixed plate 45, wherein the first track guide frame 41 is a special-shaped structure, wherein the upper portion is a horizontal straight line type, the lower portion is a vertical straight line type, and the angle between the upper portion and the lower portion is a 90° arc transition; the second track guide frame 42 is a vertical straight line type, and is welded to the side wall of the coke oven coal tower at a certain distance from the first track guide frame 41, and is welded and fixed between them The bottom track frame 43 is a double-track integrated structure equidistant from the first track guide frame 41 and the second track guide frame 42, the upper part of which is welded to the first track guide frame 41 and the second track guide frame 42, and the lower part is fixed to the ground by anchor bolts; the upper part of the bottom movable rail 44 is assembled with the bottom track frame 43 through a connecting shaft 447, and the lower part is assembled with the bottom track frame 43 through a rotating shaft 448, thereby constituting the track guide frame of the device of the invention.

[0021] There are a plurality of fixing plates 45 , which are evenly welded between the first track guide frame 41 and the second track guide frame 42 at a certain interval to reinforce and ensure the parallelism between the first track guide frame 41 and the second track guide frame 42 .

[0022] The connection ends of the bottom track frame 43, the first track guide frame 41 and the second track guide frame 42 are arc transitions, and the angle a between them is 20-30°.

[0023] The bottom movable rail 44 is composed of a blocking wheel 441, a connecting rod 442, a rocker arm 443, a counterweight 444 and a swing rail 445, wherein there are two rocker arms 443, two swing rails 445 and two guide wheels 441, the two swing rails 445 are arranged equidistantly from the bottom track frame 43, and the upper part is hinged to the bottom track frame 43 through a connecting shaft 447; one end of the two rocker arms 443 is respectively welded to the outer side of the swing rail 445, and the other end is hinged through a connecting rod 442, and the middle end near the swing rail 445 is hinged to the bottom track frame 43 through a rotating shaft 448; the counterweight 444 is assembled on the connecting rod 442, and the two guide wheels 441 are respectively arranged at the end near the swing rail 445 of the rocker arm 443, which can prevent the single-bucket trolley from rushing out of the track during the falling process.

[0024] During operation, when a sufficient amount of residual coal is collected in the single-bucket trolley, the bottom movable rail 44 is pressed to touch the limit device to give a start command to the drive device. Driven by the drive device, the single-bucket trolley of the inventive device moves up to the intersection of the horizontal track and the vertical track of the first track guide frame 41, and changes direction, from vertical upward to horizontal left movement, so that the single-bucket trolley automatically flips over to pour out all the residual coal in it; after that, the single-bucket trolley descends to the bottom, automatically docks with the lower coal hopper through the flipping spout, continues to receive the residual coal, and completes a working cycle.
