The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 and 2, the present invention provides an embodiment of a quick-release chute observation door, which comprises a cover plate 201 disposed on the chute observation hole 101, a supporting and limiting part disposed on the chute wall 102,
the supporting and limiting part comprises two pairs of supporting and limiting plates 202 which are oppositely arranged on the chute walls 102 on the left side and the right side of the cover plate 201, wherein one pair of supporting and limiting plates 202 is positioned on the upper part of the cover plate 201, and the other pair of supporting and limiting plates 202 is positioned on the lower part of the cover plate 201. All span the activity on every supporting part that supports limiting plate 202 and support and be provided with a crossbeam 203, threaded fit has three can support tight complex tensioning bolt 204 with apron 201 on the crossbeam 203, supports tight complex tensioning bolt 204 with apron 201 and can make crossbeam 203 both ends stop the position cooperation with the spacing portion on the corresponding supporting limiting plate respectively.
If meet chute jam incident, loosen tensioning bolt 204 on each crossbeam 203, the screw rod tip of tensioning bolt 204 separates with apron 201 surface for crossbeam 203 both ends break away from separately with the spacing portion on the support limiting plate that corresponds respectively, tear open crossbeam 203 that supports on the supporting part that supports limiting plate 202, apron 201 loses pressure, and the landing comes down from chute wall 102 department, and the staff observes hole 101 through the chute and handles the inside jam problem of chute. After the blockage problem is processed, the cover plate 201 is covered on the chute observation hole 101, all the cross beams 203 on the supporting limiting parts are correspondingly arranged on the supporting parts of the supporting limiting plate 202 respectively, the tensioning bolt 204 is screwed, the end part of the tensioning bolt 204 is in contact with the outer surface of the cover plate 201, the cross beams 203 and the limiting parts on the supporting limiting plate are gradually in stop fit until the end part of the tensioning bolt 204 is tightly abutted to the outer surface of the cover plate 201, and the cover plate 201 is installed. Simple to use, and the dismouting is quick, moreover because tensioning bolt 204 does not with the chute direct contact, has slowed down the corrosion problem that brings because of the moist environment in the chute. And tensioning bolt 204 in this embodiment need not to dismantle from crossbeam 203 in the use, only need make the both ends of crossbeam 203 with support spacing portion on the limiting plate break away from can, consequently do not have original hole or step such as to sell, further promoted dismouting efficiency.
As shown in fig. 2, the utility model provides a support a specific embodiment of limiting plate 202, promptly support limiting plate 202 and be L type plate body, the horizontal limit that supports limiting plate 202 is the supporting part, and the perpendicular limit that supports limiting plate 202 is spacing portion. In this embodiment, two ends of the cross beam 203 can be supported on the lateral edges of the supporting limiting plate 202, and when the end of the long bolt 204 abuts against the outer surface of the cover plate 201, the vertical edges serving as the limiting parts can be in stop fit with two ends of the cross beam 203.
In order to avoid the problems of coal leakage, water leakage, medium leakage and the like between the chute observation hole 101 and the cover plate 201, a sealing pressing sheet 205 is arranged between the cover plate 201 and the chute wall 102. Specifically, the sealing rubber sheet 205 is made of a rubber material. The sealing pressing skin 205 in this embodiment may be a sealing pressing skin 205 of an annular structure surrounded along the periphery of the chute observation hole 101, or may be a sealing pressing skin 205 of a whole piece shape, and the periphery of the sealing pressing skin 205 can cover the periphery of the chute observation hole 101. During installation, when the cover plate 201 gradually approaches the chute wall 102, the sealing pressing skin 205 is compressed and deformed, and can realize a sealing effect between the cover plate 201 and the chute wall 102 along with the change of the gap between the periphery of the cover plate 201 and the chute wall 102.
In this embodiment, there are three tension bolts 204 on each beam 203. Specifically, the end of each tension bolt 204 is located within the chute sight hole 101 area.
In order to improve the installation stability and the use fluency, nuts are fixedly arranged on the cross beam 203 corresponding to the tensioning bolts 204, and the tensioning bolts 204 can be in threaded fit with the cross beam 203 and the corresponding nuts.
