Abstract
The invention discloses a protective device of explosive-proof equipment, and belongs to the field of coal mining machinery. The protective device of the explosive-proof equipment includes perforated support columns, a protective plate and fastening screws, wherein four edges of the protective plated is folded into an L-shaped protective plate protrusion, holes are formed in the protective plate, the perforated support columns are positioned under the holes, and the fastening screws are fixed on the equipment through the holes in the perforated support columns. When the protective device of the explosive-proof equipment is fixed on the equipment through the fastening screws, rain is prevented from entering the equipment, dust retention is prevented, screws on the equipment are protected by preventing the screws from bumping against with other things, assembling and disassembling are convenient in the processes of mount and repair, labor time is saved, work efficiency is improved greatly, and structure of the protective device is simple.
Description
Technical field
The present invention relates to protector, be more particularly to a kind of explosion-proof device protector, belong to the Coal Mechanical field.
Background technology
In the mineral electrical apparatus of producing at present, the protector of screw adopts to increase and covers the thickness of flange and open the degree of depth and the groove of screw cap equal height on flange, plays the effect to the screw cap protection.Have water and flow in groove when rain drops on flange, in groove, ponding can make screw get rusty easily or water flows into device interior from screw hole equipment is caused damage; And the time grown easy laying dust.Its difficulty of processing is large, and in the installation and maintenance process dress, tear inconvenience open, bring inconvenience to the user.
Summary of the invention
The objective of the invention is to overcome above deficiency, a kind of simple and reliable, easy to use, a kind of explosion-proof device protector of saving man-hour is provided; It can prevent that rainwater from flowing into equipment, prevents laying dust, greatly increases work efficiency.
A kind of explosion-proof device protector comprises support column with holes, protective plate, trip bolt, and the protective plate surrounding becomes along edge break " L " type protective plate projection; Protective plate is provided with the hole, is provided with support column with holes below described hole, and trip bolt passes that on support column, the hole is fixed on equipment.
Described support column with holes is welded on the protective plate of bottom in described hole.
The invention has the beneficial effects as follows: when a kind of explosion-proof device protector is fixed on equipment by trip bolt; Just can prevent that rainwater from flowing into equipment, prevent laying dust, the screw on protection equipment prevents that the screw on equipment from being collided with, and fills in the installation and maintenance process, tears open conveniently, thereby save man-hour, greatly increases work efficiency; It is simple in structure.

Fig. 2 is vertical view of the present invention.
Fig. 3 is that the present invention is arranged on the structural representation on explosion-proof device.
Fig. 4 is that the present invention is arranged on the vertical view on explosion-proof device.
Fig. 5 is the structural representation of the protector of screw in the mineral electrical apparatus of producing at present.
EmbodimentDescribed in detail below in conjunction with accompanying drawing
A kind of explosion-proof device protector comprises support column with holes 1, protective plate 2, trip bolt 3, and protective plate 2 surroundings become along edge break " L " type protective plate projection 4; Protective plate 2 is provided with the hole, is provided with support column with holes 1 below described hole, and described support column 1 with holes is welded on the protective plate of bottom in described hole.Trip bolt 3 passes that on support column 1, the hole is fixed on equipment.Support column 1 with holes adopts the processing of diameter 8 ~ 35mm round steel; It is that 3 ~ 5mm steel plate processes that protective plate 2 adopts thickness.
When a kind of explosion-proof device protector is fixed on equipment by trip bolt 3; Just can prevent that rainwater from flowing into equipment, prevent laying dust, the screw 5 on protection equipment prevents that the screw 5 on equipment from being collided with, and fills in the installation and maintenance process, tears open conveniently, thereby save man-hour, greatly increases work efficiency; It is simple in structure.
The present invention is applied in mineral explosion and flame-proof type low-voltage protection box for mining, is used for the protection that junction box's cover plate tightens screw.
