Abstract
The utility model discloses a novel self-closing type safety protective door. Inner stand columns are respectively arranged at two sides of a self-unloading platform, the inner stand columns at two sides are respectively provided with a hinged door body through a hinge, each of the inner stand columns at two sides inclines towards the inner side by an angle alpha, outer stand columns are respectively arranged at the outer sides of the inner stand columns at two sides, the outer side of each of the door bodies at two sides extends towards outwards to form an extension portion, and the width of each extension portion is larger than the distance between each outer stand column and each inner stand column. The novel self-closing type safety protective door achieves the purpose of automatic closing by utilizing the gravity of the door bodies, achieves self-closing, and eliminates the troublesome operation that the protective door is manually closed after each time of loading and unloading. After the novel self-closing type safety protective door is installed for use, human assistance is not needed in the process of closing the protective door, the protective door is closed automatically, and the self-closing rate reaches above 98%.
Description
Technical field
The utility model relates to safety protective door improvement technology in the building field, is specifically related to a kind of self-closing security protection gate.
Background technology
When tier building is constructed in building field, mainly adopt material elevator as the vertical transport instrument.But, exist a lot of not enough in making, installation and the use of traditional material hoist discharging platform safety protective door.Existing safety protection door of discharging platform has two kinds, and a kind of is to need artificial closed safe protective door, in case defective is to forget that the closed safe protective door will lose protective action, abnormally dangerous.Another kind is the safety protective door with elastic hinge, and this door body structure is complicated, and cost is high, receives restriction service life, and easily impaired, loses immediately protective action after impaired.
The utility model content
The utility model provides a kind of self-closing security protection gate for the problem and shortage that safety protective door in the existing building field exists.
The technical scheme in the invention for solving the technical problem is: a kind of self-closing security protection gate, both sides at the self-discharging platform are respectively arranged with inner column, by hinge the door body of splitting is installed respectively on the inner column of both sides, described both sides inner column difference is tilt angle alpha to the inside.
The outside at the both sides inner column is respectively arranged with outer column, and the microscler one-tenth extension of the lateral extension of two side door bodies, and the width of extension is greater than distance between outer column and the inner column.
Beneficial effect: the utility model can utilize a body self gravitation and realize the purpose of autoshutdown, realizes that protective door is self-closing, removes the loaded down with trivial details operation of manually closing protective door behind each loading, unloading material from.After self-closing security protection gate of the present utility model is installed and used, close protective door and need not human assistance, autoshutdown, and self-closing rate reaches more than 98%.
Description of drawings
Figure l is the construction profile schematic diagram of the utility model self-closing security protection gate;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is inner column and bottom surface installing condition schematic diagram among Fig. 1.
Number in the figure 1 is the self-discharging platform, and 2 is outer column, and 3 is the door body, and 4 is hinge, and 5 is inner column, and 6 is the extension bottom bar, and 7 is extension, and 8 is the vertical transport instrument.
The specific embodiment
Embodiment 1: referring to Fig. 1, Fig. 2 and Fig. 3, a kind of self-closing security protection gate, be respectively arranged with inner column 5 in the both sides of self-discharging platform, by hinge 4 the door body 3 of splitting is installed respectively on the both sides inner column 5, described inner column 5 is tilt angle alpha to the inside, because the unstable moment of torsion that exists of the door body weight heart of open mode, thus a body can be under the self gravitation effect autoshutdown.Be respectively arranged with outer column 2 in the outside of both sides inner column 5, and the microscler one-tenth extension 7 of the lateral extension of two side door bodies 3, the width of extension 7 is greater than distance between outer column 2 and the inner column 5, and outer column plays position-limiting action, prevents from the transition vibration problems occurring behind the body autoshutdown.
Embodiment 2: accompanying drawing is not drawn, and content is substantially the same manner as Example 1, and something in common does not repeat, and different is: outer column is not set, and its steadily of centre of gravity behind the door body autoshutdown no longer swings.
Claims (2)
1. self-closing security protection gate, it is characterized in that: the both sides at the self-discharging platform are respectively arranged with inner column, by hinge the door body of splitting are installed respectively on the inner column of both sides, and described both sides inner column is tilt angle alpha to the inside respectively.
2. self-closing security protection gate according to claim 1, it is characterized in that: the outside at the both sides inner column is respectively arranged with outer column, and the microscler one-tenth extension of the lateral extension of two side door bodies, the width of extension is greater than distance between outer column and the inner column.
