Abstract
An anti-falling support for an installation screen board comprises a hollow rectangular steel, wherein the hollow rectangular steel is molded by being bent for three times, one side is provided with an opening, the side adjacent to the side which is provided with the opening is provided with at least two assembly holes, the side opposite to the side which is provided with the assembly holes is provided with at least two round holes; an anti-falling support platform is arranged at one end of the hollow rectangular steel of which one side is provided with the opening; one inclined side is arranged at the end part of the anti-falling support platform. The inclined side which is arranged at the end part of the anti-falling support platform provides the front guide for assembling the installation screen board so that the installation screen board is convenient to install; the support platform bears one part of gravity of the installation screen board and secondary components assembled on the installation screen board, consequently the falling problem of the installation screen board is solved when the secondary components are installed on the spot and the stuck phenomenon of a manual bolt and the installation screen board, which is caused by the deformation of the installation screen board after spot hoisting and long-distance transport, is avoided.
Description
Technical field
The utility model belongs to the metal clad switchgear technical field, relates to a kind of installation screen board fall arrest support specifically.

At present, the Quadratic Finite Element device mounting screen board (double-acting door) of Chang Yong 10kV metal clad switchgear secondary meter case often is directly fixed on by hand-tight screw the screen board support is installed.After the Quadratic Finite Element device is covered with the installation screen board; because the deadweight of screen board and Quadratic Finite Element device is installed; screen board is installed usually can be occurred tilting or the phenomenon of falling; after through on-the-spot lifting and long-distance transport; hand-tight screw stuck phenomenon often occurs with the installation screen board; hand-tight screw can't normally screw or unscrew, and can't lean on human body self strength to screw or unscrew.
Summary of the invention
At above-mentioned situation, the utility model provides a kind of installation screen board fall arrest support, occur tilting or the phenomenon of falling owing to the gravity of the Quadratic Finite Element device that is covered with and self to solve present installation screen board, cause hand-tight screw and the problem that screen board is stuck, can't lean on human body self strength normally to screw or unscrew is installed.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of installation screen board fall arrest support, it is characterized in that, comprise three bending and moldings, wherein a side is provided with the hollow rectangle steel of opening, the described side adjacent with a side that is provided with opening is provided with at least two pilot holes, and the described side relative with the side that is provided with pilot hole is provided with at least two circular holes; An end that is provided with the hollow rectangle steel of opening in a described side is provided with a fall arrest support platform.
Further, described fall arrest support platform comprises a flanging that is provided with outside bending 90 degree of lateral ends of at least two pilot holes by described; These flanging both sides be respectively arranged with downward 90 the degree contour flangings, the end be provided with downward 30 ~ 60 the degree, with the contour flanging of two side edgefolds, the flanging of end flanging and both sides welds together.
Further, described pilot hole is positive hexagon ring, is respectively arranged with riveting nut in the hole.
Further, the width of described hollow rectangle steel opening is not less than 8mm.
Further, sheet metal thickness of the present utility model is 1.5 ~ 3mm.
The beneficial effects of the utility model are, the bottom support that screen board is installed is on support platform of the present utility model, make support platform of the present utility model bear the gravity of a part of installation screen board and the Quadratic Finite Element device that is fitted thereon, screen board tenesmus phenomenon is installed when having solved on-the-spot installation Quadratic Finite Element device, has avoided on-the-spot lifting and long-distance transport back because of the screen board distortion is installed hand-tight screw that causes and the stuck phenomenon that screen board is installed.The installation that being set to of support platform end 30 ~ 60 degree flangings installed screen board provide leading to, make and install when screen board part gravity is born by the utility model and can also assemble very easily.
Description of drawings
Fig. 1 is a kind of structural representation that screen board fall arrest support is installed of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of installation screen board fall arrest support, comprise three bending and moldings, wherein a side is provided with the hollow rectangle steel 100 of opening 111, the described side 120 adjacent with a side 110 that is provided with opening 111 is provided with at least two pilot holes, and the described side 130 relative with the side 120 that is provided with pilot hole is provided with at least two circular holes 131; An end that is provided with the hollow rectangle steel 100 of opening 111 in a described side is provided with a fall arrest support platform 200.
Described fall arrest support platform 200 comprises a flanging 210 of being spent by the described outside bending 90 in end that is provided with the side 120 of at least two pilot holes; These flanging both sides are respectively arranged with the contour flangings 220 of downward 90 degree, the end be provided with downward 30 ~ 60 degree, with the contour flanging 230 of two side edgefolds, end flanging 230 welds together with the flanging 220 of both sides.
Described pilot hole is positive hexagon ring, is respectively arranged with riveting nut 121 in the hole.The width W of described hollow rectangle steel opening 111 is not less than 8mm.Sheet metal thickness of the present utility model is 1.5 ~ 3mm.
During use, at first adopt bolt fastener the utility model to be fixed on the relevant position of shrouding behind the metal clad switchgear secondary meter case by the circular hole on the side 130 131, doing guiding by flanging 230 of the present utility model again will install screen board and be placed on the fall arrest support platform 200 of the present utility model, hand-tight screw is tightened by installing hole and riveting nut of the present utility model 121 that screen board is installed, thereby the installation screen board is fixed on a kind of installation screen board of the utility model fall arrest support.
