Abstract
The utility model relates to a segmented hinge seat for corridor safety door for construction elevator, which in characterized in that the utility model comprises rivets, a left semi-circle hinge seat, a right semi-circle hinge seat, screw bolts, a limit corner step and a jack. One end of the left semi-circle hinge seat is concave, one end of the right semi-circle hinge seat is convex, and after the concave and the convex ends are tightly meshed, the concave and the convex ends are connected via the rivets. The other ends of the left semi-circle hinge seat and the right semi-circle hinge seat can be connected via the screw bolts, the outside of the middle ends of the left semi-circle hinge seat and the right semi-circle hinge seat is provided with limit corner steps whose inner roof corners are provide with the jack which can be used to plug a door. The jack can be installed on standing poles at the both sides of the elevator, after the safe door is plugged, the safe door is opened in a finite angle and blocked by the limit corner step. The utility model has the advantages of reliable structure and convenient and simple dismounting and mounting, and the segmented hinge seat for corridor safety door for construction elevator can control the abversion angle of opening of the safe door.
Description
Technical field
The utility model relates to a kind of active free bearing that is used for building hoist corridor safety door, is the adjustable load-supporting part of safety door, belongs to construction safety gate technique field.
Background technology
The safety door free bearing sees it is that L type bearing pin is welded in the building hoist vertical rod or employing book iron sheet rolls folder more at present, do not possess the opening angle effect of control safety door, in case the latch of safety door is not plugged, because door outwards produces, the operation up and down of building hoist will directly be influenced, the normal safety door that takes place breaks, even the high-altitude falls, and brings serious potential safety hazard to building operation.
Summary of the invention
The purpose of this utility model is a kind of outer commentaries on classics opening angle that can control safety door of invention, reliable in structure, and easy accessibility simply is used for the active free bearing of building hoist corridor safety door.
For realizing above purpose, the technical solution of the utility model provides a kind of active free bearing that is used for building hoist corridor safety door, its characteristics are, form by rivet, left semicircle free bearing, right semicircle free bearing, bolt, limit angle step, jack, left semicircle free bearing one end is spill, right semicircle free bearing one end is convex, connect by rivet after the machicolated form end tight engagement, the left semicircle free bearing, the right semicircle free bearing other end can be by bolted connection, the external finite angle step of the middle-end of left semicircle free bearing, right semicircle free bearing, the interior drift angle of limit angle step is equipped with the jack that door is inserted in a confession.
The utility model adopts existing building hoist vertical rod to make doorframe, and active free bearing is contained in the vertical rod, then the latch on the safety door is inserted in the jack of limit angle step, is promptly blocked by limit angle step after door is opened certain angle, has avoided hidden danger.
The utility model has the advantages that:
1. adopt the building hoist vertical rod to make doorframe, needn't establish doorframe in addition;
2. the utility model can be installed on any position in the building hoist vertical rod, realizes any adjusting of safety door height;
3. owing to can control the outer commentaries on classics opening angle of safety door,, do not influence the operation up and down of building hoist yet, avoid safety door to break and fall with the high-altitude even latch is not plugged in the middle of the two fan doors;
4. reliable in structure, easy accessibility is simple, and is reusable, cost-cutting.
Description of drawings
Fig. 1 is the active free bearing structural representation that is used for building hoist corridor safety door;
Fig. 2 is the structural representation after door is loaded onto.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, for being used for the active free bearing structural representation of building hoist corridor safety door, form by rivet 1, left semicircle free bearing 2, right semicircle free bearing 3, bolt 4, limit angle step 5, jack 6.
Adopt 20# aluminium close cast left semicircle free bearing 2 and right semicircle free bearing 3, make left semicircle free bearing 2 one ends be spill, right semicircle free bearing 3 one ends are convex, diameter specifications is pressed the vertical rod diameter of building hoist and is decided, the external finite angle step 5 of the middle-end of left semicircle free bearing 2, right semicircle free bearing 3, the interior drift angle of limit angle step 5 is equipped with the jack 6 that door is inserted in a confession.
As shown in Figure 2, press the height of safety door latch, two active free bearings respectively are installed in the vertical rod of the both sides of building hoist, 3 liang of slit bamboo or chopped wood half gardens of left semicircle free bearing 2 and right semicircle free bearing clamp the vertical rod of building hoist, a left side half
Fixing after the machicolated form end tight engagement of circle free bearing 2 and right semicircle free bearing 3 by rivet 1, left semicircle free bearing 2, right semicircle free bearing 3 other ends can be fixing by bolt 4, the latch of safety door is inserted in the jack 6 on the interior drift angle of limit angle step 5, opening safety door is promptly limit angle step 5 to block to certain angle.
