Abstract
The utility model discloses an automatic protecting device for a portal frame, which is widely applied to material lifting operation on construction sites. Two guide wheels 4 are respectively fixed on protecting frames on two sides of the portal frame by steel tubes; the heights of the two guide wheels are required to be positioned on the same horizontal plane; two first steel wire ropes 3 respectively penetrate through grooves of the two guide wheels 4; one end of each steel wire rope 3 is connected with a protecting door 5; the other end of each steel wire rope 3 is connected with a driving rod 1 through a material tray 2; and two ends of the protecting door 5 are hung at a feed opening of the portal frame by the steel wire ropes 3 through the guide wheels 4. In the automatic protecting device, by using the lifting dead weight of the material tray of the portal frame as a power source, the protecting door is driven to automatically lift by the steel wire ropes and the guide wheels without additionally consuming energy sources; the automatic protecting device is convenient to mount and simple to use; the operation is not needed to be watched by a special person; the automatic degree for safety protection of a discharge opening is high; operators are effectively prevented from coming in and going out freely; and the safety is ensured and the work efficiency is improved.
Description
Technical field: the utility model relates to a kind of portal frame automatic protection device of using when the building ground promotes the material operation of being widely used in.
Background technology: at present,, in the tier building work progress, all will use portal frame material bont along with improving constantly of level of mechanization.But, all have great security breaches therebetween, after promptly material disc promotes, formed a hole that the workman can pass in and out arbitrarily at ground inlet point place, even if some engineering has been taked some measures, done some interim protection, but because of not having regularization, mechanization, open inconvenient, it is bothersome to take a lot of work, and performs practically no function, and causes the ground feed inlet and outlet, is in unshielded state, there is bigger potential safety hazard, causes bottom operating personnel's injures and deaths.
The utility model content: the utility model efficiently solves the drawback that former portal frame material bont exists, and a kind of simple, safe in utilization simple and direct portal frame automatic protection device of making of knowing clearly is provided.The technical scheme that its technical matters that solves the utility model adopts is: described two track adjusting wheels 4 are fixed on the protective frame of portal frame both sides with steel pipe respectively, it highly will be on a horizontal surface, two first steel ropes 3 pass in two track adjusting wheels, 4 grooves respectively, one end is connected with protective door 5, one end is connected with drive link 1 by material disc 2, protective door 5 two ends hang over portal frame inlet point place by track adjusting wheel 4 with steel rope 3.
The beneficial effects of the utility model are: owing to utilize portal frame material disc lifting deadweight as propulsion source, by steel rope and track adjusting wheel, drive the protective door automatic lifting, do not need the additive decrementation energy, and easy for installation, use simply, need not establish the special messenger and keep an eye on operation, discharging opening safety precaution degree of automation height, prevented that effectively the operating personnel from arbitrarily coming in and going out, not only guaranteed safety but also improved work efficiency.
Description of drawings: Fig. 1 is a front view of the present utility model.
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment: as shown in Figure 1 and Figure 2, described two track adjusting wheels 4 are fixed on the protective frame of portal frame both sides with steel pipe respectively, it highly will be on a horizontal surface, two first steel ropes 3 pass in two track adjusting wheels, 4 grooves respectively, one end is connected with protective door 5, one end is connected with drive link 1 by material disc 2, and protective door 5 two ends hang over portal frame inlet point place by track adjusting wheel 4 with steel rope 3; Material disc 2 tops are connected with winch by the guide rail of portal frame both sides and the pulley at top by one second steel rope 6.
Principle of work of the present utility model is: steel rope one end is a drive link, utilize portal frame material disc lifting deadweight as propulsion source, when material disc lands, pressing drive link to descend jointly, by steel rope and track adjusting wheel, drive the protective door automatic lift, after installing need lifting material, along with the rising of material disc, drive link pressure is removed, protective door is slowly falling under the effect of gravity, and up to falling earthward, the portal frame inlet point is lived in protection.Realize the automatic lifting of ground feed inlet and outlet safety protective door, be safety precaution propulsion source is provided, guaranteed the personal security of portal frame material mouth again.
