Embodiment 1

[0036] refer to Figure 1~3 , which is the first embodiment of the present invention, this embodiment provides a stacker-reclaimer coal drop pipe diverter door angle adjustment buffer device, which includes an angle adjustment assembly 100 and a coal drop assembly 300, the angle adjustment assembly 100 is arranged at the drop The outer wall of the coal assembly 300 is used to control the mixing ratio of the two coals in the coal drop assembly 300 .

[0037] The coal drop assembly 300 includes a coal drop pipe 301, a shunt door 302 and a rotating shaft 303. The coal drop pipe 301 is an existing device, and the shunt door 302 is a square plate structure, which is arranged inside the coal drop pipe 301, and the rotation shaft 303 passes through the The coal drop pipe 301 is erected on the outer walls of both sides of the coal drop pipe 301, and then one end of the diverter door 302 is fixed on the rotating shaft 303. The rotation of the rotating shaft 303 can drive the diverter d...

Embodiment 2

[0044] refer to Figure 4-10 , is the second embodiment of the present invention, this embodiment is based on the previous embodiment, and further includes a buffer assembly 200 , the buffer assembly 200 is arranged on both sides inside the installation shell 101 and is movably connected with the angle adjustment assembly 100 .

[0045] The buffer assembly 200 includes a lifting member 201, a floating block 202 and a gear 203. Specifically, the lifting member 201 includes a first elastic member 201a and a block 201b. The bottom is provided with a second elastic member 201b-2, and the other end of the second elastic member 201b-2 is fixedly provided with an insert 201b-3.

Abstract

The invention discloses a stacker-reclaimer coal drop pipe shunting door angle adjusting buffer device which comprises an angle adjusting assembly and a buffer assembly, the angle adjusting assembly comprises a mounting shell, a push plate, a hinge plate and a rotating block, the two sides of the push plate are slidably connected with the inner wall of the mounting shell, one end of the hinge plate is hinged to the push plate, and the other end of the hinge plate is hinged to the rotating block. The buffer assembly comprises lifting pieces, floating blocks and gears, the lifting pieces are arranged on the two sides of the inner wall of the mounting shell and connected with the push plate, the floating blocks are arranged in the inner walls of the two sides of the mounting shell, and the gears are mounted on the floating blocks. The stacker-reclaimer coal drop pipe shunting door angle adjusting buffer device is short in response time, high in environment adaptability and high in reliability, has a certain buffering distance, and avoids the situation that a shunting door is damaged due to errors of a push rod motor.

Description

technical field [0001] The invention relates to the technical field of angle adjustment of a coal drop pipe diversion door, in particular to a buffer device for adjusting the angle of a coal drop pipe diversion door of a stacker-reclaimer. Background technique [0002] Today, under the dual pressure of environmental protection and high coal prices, and on the premise of ensuring that the environmental protection indicators meet the standards, power plants use more good coal and poor coal for blending to reduce power generation costs. When coal enters the raw coal bunker from the wharf through the coal drop pipe of the stacker-reclaimer, if the blending plan of the two types of coal is implemented, the driver changes the coal flow in the coal drop pipe by adjusting the position of the diverter door. Although the coal flow rate can be known through the belt scale on the downstream belt conveyor, the feedback time is too long for one reason, and it needs to be conveyed through ...
