Embodiment Construction

[0023] see figure 2 And Fig. 3, a kind of cam control device that is used for dustproof device turnover plate of the present invention is installed on the dustproof device, and dustproof device is equipped with dustproof device casing 2 and dustproof device turnover plate 3. The cam control device is installed beside the side of the supporting roller 1, and can be installed on one side of the supporting roller 1, and can also be installed on both sides of the supporting roller 1.

[0024] A cam 4 is housed in the dustproof device casing 2, and a camshaft 5 is fixedly arranged on the cam 4. The axle end of camshaft 5 is equipped with wrench, is convenient to rotate camshaft 5. Cam cover plate 8 is housed above cam 4. The upper end of the cam cover plate 8 is connected with the dust-proof flap 3 through a living hinge 9 . The cam cover plate 8 has a certain discharge angle during work, which can prevent the material blocks from accumulating on the cover plate surface, and pre...

Abstract

The invention relates to a cam control device used for a reverse turning bed of a dust excluder, which comprises a riding wheel, a case body of the dust excluder and the reverse turning bed of the dust excluder, wherein, a cam is arranged in the case body of the dust excluder; a cam shaft is fixed on the cam; a shifting shaft is fixed on the lower end part of the reverse turning bed of the dust excluder; two ends of the shifting shaft are respectively embedded in a slotted hole on side surfaces of the case body; the upper end part of the reverse turning bed is provided with a blade; the blade is closely attached on the surface of the riding wheel while working. The invention controls the stability of the reverse turning bed of the dust excluder and the blade in working state by a cam mechanism, leads the reverse turning bed of the dust excluder to be quickly opened backwards by the rotation of the cam so as to expose a cleaning inspection area under the riding wheel with larger space, and prevents block of the riding wheel and deposition of splashed materials under the riding wheel. An operator can achieve clear and quick cleaning inspection only by simple operation, so that the standing time of the operator in a dangerous place can be reduced, and the safety factor for production is improved.

Description

technical field [0001] The invention relates to a trolley in an ironworks, in particular to a cam control device for a dust-proof flap of a supporting wheel on a running track of the trolley. Background technique [0002] The ironmaking plant mixes the ironmaking raw materials to make pellets and then sinters them. The granulated spherical ore is poured into the trolley of the belt cooler. The trolley moves slowly through flexible transmission traction and runs on the track. Send it to the high-temperature zone for sintering. The calcination temperature reaches about 700°C, and then it is forced to blast to cool it to about 150°C to complete the sintering process and enter the next process. [0003] The running track of the trolley is composed of many support wheels symmetrically installed on both sides of the steel structure support. There is a certain distance between adjacent support wheels, but it is guaranteed that there are at least four sets of support wheels and the ...
