Abstract

The utility model discloses an automatic protecting device of gantry feed inlet, which is widely used on construction sites for lifting materials, wherein two guiding wheels (4) are respectively fixed on protective frames on two sides of the gantry by steel pipes, and the heights of the two guiding wheels are on one horizontal surface, two first steel wire ropes (3) are respectively penetrated through the grooves of the two guiding wheels (4), one ends thereof are connected with a protective door (5), and the other ends are connected with a drive rod (1) through a material disc (2), and two ends of the protective door (5) are hung on the feed inlet of the gantry by the steel wire ropes (3) through the guiding wheels (4). Since the automatic protecting device of gantry feed inlet utilizes the lifting self weight of the material disc of the gantry as a power source, the protective door is driven to automatically lift through the steel wire ropes and the guiding wheels, energy source is not needed to be additionally consumed, and the automatic protecting device of gantry feed inlet has convenient installation and simple use, which does not need a person to take charge and operate, and the safe protective automatic degree of a discharge hole is high. The automatic protecting device of gantry feed inlet effectively prevents operation staffs from getting in and out at random, not only guarantees security, but also improves working efficiency.

Description

Portal frame inlet point automatic protection device
Technical field:
The utility model relates to a kind of portal frame inlet point automatic protection device of using when the building ground promotes the material operation of being widely used in.
Background technology:
At present, along with improving constantly of level of mechanization, in the tier building work progress, all to use portal frame material bont.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 inlet point automatic protection device of making of knowing clearly is provided.Two track adjusting wheel 4 is 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 by material disc 2) be connected with drive link 1, protective door 5 two ends hang over portal frame inlet point place by track adjusting wheel 4 with steel rope 3.Because the utility model utilizes 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, 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.

Claims (2)

1, a kind of portal frame inlet point automatic protection device, it is characterized in that 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) groove 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).
