Abstract
The utility model provides an auto-close ladder protective fence which is arranged on the top of a factory vertical ladder at the part with the height the same as that of the protective fence. The proper position of a left ladder column of the vertical ladder is drilled to be fixedly provided with a hydraulic hinge, and the other fan of the hinge is fixedly provided with a steel pipe which has the proper length and is pored, so that the possible staff falling since the vertical ladder is not provided with the protective fence can be offset. The automatic close of the protective fence can be realized according to the automatic extension function of the hydraulic hinge.
Description
Affiliated technical field
The utility model relates to a kind of helper protective guard, belongs to factory's eminence personal protection safety device.
Background technology
Eminence tower district of factory generally have People's Bank of China's inclined ladder or vertical ladder sensible, be convenient to the upper and lower of personnel.The Ta Qu of factory appropriate location operated by rotary motion platform is convenient to personnel inspection or operation use, and platform adds protective guard protection personnel around and falls from edge.But vertical ladder forms hole passing through after tower district platform, and the existence of hole easily causes falling carelessly of platform operating personnel to cause injures and deaths.When hole has been solved by patent 201220243026.5 in the time that platform is inner.In the time that vertical ladder is welded on platform circumference, the fixed protective guard of platform surrounding has to disconnect one section.Although also there is self-protection hurdle vertical ladder periphery, the hole that vertical ladder self forms still can cause that personnel are casual to fall.Described this place's protective guard that is applied to of patent 201220088268.1 adopts fixing welded type and is with baseboard, exists and trips current personnel and current inconvenient defect.
Summary of the invention
Easily trip the personnel of passing through and cause new injury for overcoming the current inconvenience of fixed protective guard and baseboard, the utility model is cancelled described baseboard, and changes fixed protective guard into automatically closing.
The utility model addresses this problem adopted technical scheme: choose the hydraulic hinge of current mature technology, this hinge nature extended configuration is 180 ° of two fan angles, and 90 ° of the compressible one-tenth maximums of two fans also can be launched naturally.The steel pipe that polishes off burr of fixing a length 35-40cm diameter 3-5cm with bolt on a fan of hinge is (for ease of being connected of round steel pipe and plane hinge, need flatten and hole powerful steel pipe one end according to hinge shape and perforate), another fan of hinge is fixed on vertical ladder top with bolt by corresponding perforate, and fixed position is higher than platform plane 95-110cm place.Because vertical ladder width is about 60cm, select length 35-40cm steel pipe both can ensure the interspace personnel that can not drop, area inswept when being also convenient to this protective guard and being opened is less, does not hinder the personnel that are about to current or operation on platform.
The beneficial effects of the utility model are:
The hydraulic hinge of 1 selected technology maturation, reduces the workload of constructing in the factory workload of welding of especially getting angry, thereby reduces the process units security risk in rich accumulation of oil and gas district.
The hydraulic hinge that 2 technology maturations, market are easy to get has than more good quality and long life more of the restoring spring of free accessory assembling.The hydraulic hinge nature of choosing keeps 180 °, just in time protective guard default platform is done to extend, and can resist the supporting role that personnel rely on protective guard to play.
The automatic closing function of 3 hydraulic hinges, can automatic homing after personnel are passed through, and recovers safeguard function, and the personnel of preventing do not playback and cause protection actual effect.
4 selected protection do not cover whole vertical ladder breach with steel pipe, are on the one hand the stayed breach personnel that can not fall, and in the time that protective guard is opened, on platform, inswept area is as far as possible little on the other hand, to reduce the obstruction to operating personnel on platform.
5 movable protective guards are convenient to pass through, and skirtless plate can avoid current personnel to trip and cause new injury.
brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Tu1Shi Ta district vertical ladder and guardrail figure.In figure, 1 is vertical ladder, the 2nd, and protective guard, the 3rd, platform, the 4th, default guardrail.
Fig. 2 is selected hydraulic hinge and steel pipe schematic diagram.In figure, 1 is steel pipe, and 2 is the perforate on steel pipe, the 3rd, and hydraulic hinge.
detailed description of the invention
In Fig. 1, the 1st, for the vertical ladder of the upper and lower tower body of personnel platform climbing; The 2nd, platform is the edge protection hurdle of welding around, highly about 95-110cm; The 3rd, horizontal welding is connected to the platform of tower body; The 4th, the position that Terrace prevention hurdle is default because of vertical ladder, is also the place that the utility model is installed.
Now choose the segment length 35-40cm as shown in Fig. 21, the steel pipe of diameter 3-5cm, polish off sharp parts, then will after powerful steel pipe one end flattening, open the hole as shown in 2, hole size should be corresponding with hydraulic hinge 3 with spacing.The natural extended configuration of hinge 3 is 180 ° of two fan angles, and two fans close up rear minimum angle and are no more than 90 °.
Complete after material preparation described above, carry out in the following manner scene and install:
One, hydraulic hinge is installed: according to selected hydraulic hinge, keep hinge vertical, one fan is adjacent to the left cleat stanchion of vertical ladder, height 95-110cm At The Height, another fan can freely, please be adjusted if direction is anti-loaded in time to platform inner side (making sure to keep in mind: direction is anti-loaded will lose safeguard function) folding.The perforate of hinge is signed on the left cleat stanchion of being close to marking pen; Use Churn drill in mark perforate, perforate is complete is that available suitably large stove bolt is fixed to hydraulic hinge on the left cleat stanchion of vertical ladder again.
Two, protective guard is installed: according to the perforate of another fan of mounted hydraulic hinge, the steel pipe of a selected length 35-40cm diameter 3-5cm is kept to level, keep corresponding with another fan perforate of hydraulic hinge, then steel pipe and hydraulic hinge are fixed with suitable stove bolt greatly.Complete installation of the present utility model.
Claims (1)
1. an automatic closed helper protective guard, is characterized in that: this protective guard is made up of a hydraulic hinge and a steel pipe; Hinge be installed on factory ascend a height the top of vertical ladder, higher than platform 95-110cm place, steel pipe length 35-40cm, diameter 3-5cm; The connected mode of vertical ladder and hinge, hinge and steel pipe is bolt; On vertical ladder, steel pipe, perforate size is consistent with spacing and hinge perforate.
