Abstract
The utility model discloses a changeover valve control device whose shell top is provided with an air outlet connector. The circumference of the connector bottom is provided with a sealing ring which contacts with a flash board which is connected with a bracket. The utility model is also provided with a lever type rotary arm with the pivot hinged on the changeover valve shell and the resistance force pivot hinged on the bracket and the motion point provided with a pulley. A glide way that matches the pulley is installed on the movable discharge vehicle. When the movable discharge vehicle travels to certain mine groove, the glide way on the movable vehicle is inserted under the pulley on the rotary arm. The rotary arm is lifted to operate the flash board to move down to the seal, so as to suck the powder to a dedusting wind pipe. After finishing discharging, the glide way on the discharge vehicle will leave the pulley, the rotary arm and the pulley will be suspended due to the self-weight to automatically close the flashboard. The utility model has simple structure, reliable performance, low rate of malfunction and good dedusting effect.
Description
Technical field
The utility model relates to the dusting apparatus on a kind of mobile dummy car, specifically is a kind of switching valve control gear of controlling the dedusting air quantity.
Technical background
Mobile dummy car can gush out a large amount of dust at discharge opening when the groove discharging of ore deposit, need in the discharge opening both sides dusting apparatus to be set, and dust is evacuated to dedust air duct by the exhausting arm that switching valve is housed.At present, the dedusting air quantity of groove top, ore deposit mobile dummy car adopts electric valve to switch more, and promptly mobile dummy car is when the groove discharging of a certain ore deposit, and corresponding dedusting valve is just opened, and the electric valve on other ore deposit groove dedust air duct is closed.But because electric valve and electric interlock control switch contact are influenced by dust, easy break-down causes switching malfunctioning.
Summary of the invention
The purpose of this utility model is to provide a kind of by air quantity switching valve and the machinery action that the switching driving mechanism matches, and realizes switching a kind of switching valve control gear of air quantity.
The technical solution of the utility model is: in the switching valve cover top portion air outlet joint that connects the exhausting arm is arranged, the joint base layer perimeter is equipped with seal ring, the flashboard of the support of ining succession that contacts with seal ring.A lever-type pivoted arm is arranged, and fulcrum is hinged on the switching valve shell, and resistance is point articulated on support, and pulley is being assembled in power point position.Match with pulley, have a slide rail to be installed on the mobile dummy car.The utility model is matched with slide rail by the pulley on the pivoted arm with the exhausting of gate control by switching valve, realizes the open and close of gate, thereby reaches the purpose that air quantity switches.This mechanical device, simple in structure, reliable, fault is few, good dedusting effect.
Description of drawings
Fig. 1 is the tectonic maps of switching valve in the model utility;
Fig. 2 is installation, the user mode figure that switching valve cooperates with slideway.
Mode of execution
Introduce the utility model below in conjunction with drawings and Examples.
With reference to accompanying drawing, air outlet joint 2 is equipped with at switching valve shell 1 top, and the joint top has flange to connect exhausting arm 12, and the joint base layer perimeter has seal ring 3, and seal ring is that the frame at a trough of belt is embedded in Stamping Steel Ribbon.There is a shoe brake plate 4 to contact with seal ring 3, flashboard is installed on the support 5, and support is by bearing pin 7 articulated straight-arms 6, and the straight-arm the other end is fixed a pivoted arm 9, pivoted arm and straight-arm joint are hinged on the switching valve shell 1 by axle 8, and pivoted arm 9 the other ends are equipped with pulley 10.On mobile dummy car 13, the slide rail 14 of a level is housed, the slide rail two ends are downward camber line, and camber line bottom height is located the sagging position of pulley 10 deadweights.
When mobile dummy car 13 advanced to a certain mine box position discharging, the slide rail 14 on it will insert the pulley 10 times on the pivoted arm, lifts pivoted arm, handles flashboard 4 and moves down, and opens joint 2 bottoms and seals, and dust is evacuated to dedust air duct.Discharging finishes, and the slide rail on the unloading vehicle leaves pulley 10, and pivoted arm and pulley are sagging because of conducting oneself with dignity, and closes flashboard again automatically.
