Abstract
The utility model belongs to the technical field of steel ladder hand rail, the problem that sets up for solving the hand rail of underground structure access hole department provides a hidden steel ladder hand rail, including steel ladder hand rail, gliding sleeve about the followed montant of setting on steel ladder hand rail montant, a couple and iron chain for fixing steel ladder hand rail lower part horizontal pole, be provided with a sleeve on every montant of steel ladder hand rail, sleeve fixed mounting is on the inner wall of building access hole, telescopic upper end is greater than the diameter of steel ladder hand rail upper portion horizontal pole to the distance of building access hole upper surface, link up with rotatable the installation on building access hole inner wall between two sleeves, the one end of iron chain is connected with steel ladder hand rail's upper portion horizontal pole, the other end is connected with the couple. Adopt the utility model discloses can be convenient raise steel ladder hand rail and lower can reach building access hole department apron confined effect, potential safety hazard when having avoided walk up and down stairs simultaneously.
Description
Technical field
The utility model belongs to steel ladder hand rail technical field, is specifically related to a kind of concealed steel ladder hand rail.
Background technology
As unimpeded in lower channel such as fire cistern, pump house, equipment machine rooms for guaranteeing underground structure, generally all stairway step is provided with in building, but due to the current mouth narrow space of the building such as fire cistern, pump house, equipment machine room maintenance and top requires closeable slide cover, if so arrange fixing hand rail at the current mouth place of these buildings maintenance, the slide cover at top cannot close, if do not arrange hand rail, then during stair activity owing to not having hand rail can some potential safety hazards.
Summary of the invention
The utility model is the offering question solving access hole place, underground structure hand rail, provides a kind of concealed steel ladder hand rail.
The technical solution adopted in the utility model is as follows:
A kind of concealed steel ladder hand rail, comprise steel ladder hand rail, be arranged on the sleeve that can slide up and down along montant on steel ladder hand rail montant, for hook and the iron chains of fixing steel ladder hand rail lower crosspiece, the every root montant of steel ladder hand rail is provided with a sleeve, described sleeve is fixedly mounted on the inwall of building access hole, the upper end of sleeve is greater than the diameter of steel ladder hand rail upper cross bar to the distance of building access hole upper surface, described hook can be rotatably installed on building access hole inwall between two sleeves up and down, one end of described iron chains is connected with the upper cross bar of steel ladder hand rail, the other end is connected with hook.
The utility model also comprises a brace, and one end of described brace and the upper cross bar of steel ladder hand rail are rotatably connected, and the other end is detachably fixed on building access hole upper surface.
The beneficial effects of the utility model:
1. adopt concealed steel ladder hand rail of the present utility model, can easily steel ladder hand rail be risen and fall, the effect of building access hole place cover closure can be reached, avoid potential safety hazard during stair activity simultaneously.
2. the utility model makes simple, economical and practical, safe and reliable.

In figure: 1-sleeve, 2-links up with, 3-iron chains, 4-upper cross bar, 5-montant, 6-lower crosspiece, 7-building access hole upper surface, 8-brace.
Detailed description of the invention
As Fig. 1, 2, shown in 3, a kind of concealed steel ladder hand rail, comprise steel ladder hand rail, be arranged on the sleeve 1 that can slide up and down along montant 5 on steel ladder hand rail montant 5, for hook 2 and the iron chains 3 of fixing steel ladder hand rail lower crosspiece 6, the every root montant 5 of steel ladder hand rail is provided with a sleeve 1, described sleeve 1 is fixedly mounted on the inwall of building access hole, the upper end of sleeve 1 is greater than the diameter of steel ladder hand rail upper cross bar 4 to the distance of building access hole upper surface 7, described hook 3 can be rotatably installed on building access hole inwall between two sleeves 1 up and down, one end of described iron chains 3 is connected with the upper cross bar 4 of steel ladder hand rail, the other end is connected with hook 3.
In order to ensure the resistance to overturning of steel ladder hand rail, the utility model also comprises a brace 8, and one end of described brace 8 and the upper cross bar 4 of steel ladder hand rail are rotatably connected, and the other end is detachably fixed on building access hole upper surface 7.
When steel ladder hand rail of the present utility model needs to rise, by iron chains 3 by hook 2 pull-up, then mentioned by steel ladder hand rail, unclamp iron chains 3, steel ladder hand rail falls to making the lower crosspiece 6 of steel ladder hand rail to be fixed on hook 2 naturally; When steel ladder hand rail needs to fall, first mention steel ladder hand rail again by 2 pull-ups of iron chains 3 handle hook, after steel ladder hand rail puts down naturally, unclamp iron chains 3 again.
Adopt steel ladder hand rail of the present utility model, can easily steel ladder hand rail be risen and fall, when the slide cover at building access hole place needs closed, steel ladder hand rail is fallen, the effect that building access hole place slide cover is closed can be reached, when stair activity, steel ladder hand rail is risen, avoid potential safety hazard during stair activity.
