Detailed Description

The present invention is described in further detail below with reference to the attached drawings and examples, which are only used to enable those skilled in the art to more fully understand the technical features and advantages of the present invention, but do not constitute a limitation to the scope of the present invention.

Example 1

Referring to fig. 1, the utility model provides a multi-functional safety protection casing for chemical industry, the mainly used chemical production equipment machine seals the protection of splashing of preventing of department such as bearing, flange, safety protection casing is including being first cover case 1 and the second cover case 2 of arched door form (the type of falling U), and the bottom of the both sides wall face of first cover case 1 has sliding plate 8, and the bottom of the both sides wall face of second cover case 2 has sliding tray 6, and first cover case 1 links to each other with the sliding plate 8 that is located the upside among them, and second cover case 2 links to each other with the sliding tray 6 that is located the downside. One end of the first cover box 1 is embedded in one end of the second cover box 2, and a distance of about 0.5cm is formed between wall surfaces of the two embedded ends, so that the safety protection cover can move left and right through horizontal sliding between the upper sliding plate 8 and the lower sliding groove 6, and the protection volume of the safety protection cover can be adjusted. But first cover case 1 and second cover case 2's outer end (non-nested end) supports through telescopic bracket 4, and telescopic bracket 4 includes outer support tube and with correspond the interior support tube that sliding tray 6, sliding plate 8 outer end (coincide region about the non) link to each other, installs on the interior support tube to be used for being close to the adjustable stop button 3 of the flexible regulation hole matched with spring of upper end one side different height position department with processing outside the stay tube, can realize telescopic bracket 4's length adjustment. One end (lower end) of the outer support pipe, which is not provided with the telescopic adjusting hole, is arranged on a support 5, and a foot brake type universal pulley is arranged on the support 5 or a foundation bolt hole is processed on the support 5, so that two base body fixing forms of the safety protection cover are provided, and when the safety protection cover is applied to a machine seal and a bearing, the support 5 can be fixed by using a foundation bolt; when the safety shield is applied at the flange, the support 5 may be fixed or movable by means of a foot-brake type universal pulley.

Referring to fig. 2 and 3, horizontal protruding strips 9 are formed on two side wall surfaces of the first cover box 1 (the processing position is slightly higher than the sliding plate 8), horizontal sliding ways 10 which are opposite to the horizontal protruding strips 9 but have a slightly shorter length are formed on two side wall surfaces of the second cover box 2, and when the horizontal protruding strips 9 slide leftwards along the horizontal sliding ways 10, the horizontal protruding strips are blocked at the left end closed position of the horizontal sliding ways 10, so that the telescopic bracket 4 below the first cover box 1 and the sliding grooves 6 are prevented from colliding with each other.

The working principle of the multifunctional safety shield for chemical engineering is as follows: according to the equipment specification, if the coverage area of the first cover box 1 is smaller than the required protection size, the first cover box 1 is manually pulled out of the second cover box 2, so that the protection volume is increased to meet the protection size. When the protection object is a machine seal and a bearing of equipment, a support 5 of the safety protection cover is fixed on the equipment by using foundation bolts, in order to reduce the influence of equipment vibration on the installation stability of the safety protection cover, a section (namely an outer support pipe) of the telescopic support 4 connected with the support 5 can be reinforced by using a detachable cross rod 7 (namely the telescopic supports 4 positioned on the two side wall surfaces of the first cover box 1 and the second cover box 2 respectively are reinforced), and the stability of the safety protection cover is improved. When the protection object is a flange of equipment, the height positions of the first cover box 1 and the second cover box 2 are adjusted by utilizing the spring type adjustable limiting button 3 on the upper part of the telescopic support 4, the safety protection cover is moved into the flange installation position along the ground by utilizing the foot brake type universal pulley, and the safety protection cover is fixed on the ground after the protection volume is adjusted. After the safety protection cover is installed in place, the first cover box 1 and the second cover box 2 can be used for blocking splashed liquid, and the arc-shaped wall surfaces and the two side wall surfaces at the tops of the first cover box 1 and the second cover box 2 are used for guiding the splashed liquid to the installation positions of the sliding plate 8 and the sliding groove 6 below the interiors of the first cover box 1 and the second cover box 2.

Example 2

Different from the embodiment 1, the horizontal slideways 10 with two closed ends are processed on the two side wall surfaces of the second cover box 2, and the length of the horizontal raised lines 9 correspondingly processed on the two side wall surfaces of the first cover box 1 is far smaller than that of the horizontal slideways 10, so that the sliding of the first cover box 1 is limited in two directions.

The utility model has the characteristics as follows:

1) this safety protection casing can realize the protection of splashing and the possible mechanical injury of separation to the splash liquid of equipment relevant position department to play protection operating personnel's effect.
