Abstract
The utility model relates to a bagged cement car loader unpowered safety device, wherein a hook is movably installed at the front end of a long rack of a car loader, and the hook part of the hook is just capable of hooking a hanging beam device of the car loader. The upper portion of the hook is connected with cylindrical sticks. The cylindrical sticks pass through a supporting plate welded on a positioning rack of the car loader. A stretchable spring is sleeved on the cylindrical sticks between the supporting plate and the hook. The bagged cement car loader unpowered safety device fully utilizes the principle of balance force. When wrong operation occurs, or electricity is out of control, an oblique belt conveyor continuously rises to the top until a steel wire rope of a suspending device is broken, a hanging beam device of the oblique belt conveyor falls on the hook part below the hook, and the oblique belt conveyor and the hanging beam device produce downward gravity after the steel wire rope is broken, the hook is under the action of a shaft and produces upward supporting force, Therefore, the belt conveyor stands on the bagged cement car loader unpowered safety device, the rack is prevented from falling off, and the safety of people and equipment is ensured. The bagged cement car loader unpowered safety device is simple in structure and high in safety coefficient and economic and practicable.
Description
Technical field
The utility model relates to technical field of engineering machinery, particularly relates to a kind of bag-pack cement loading machine power-free safety device.
Background technology
In the prior art, most of bag-pack cement loading machines all as shown in Figure 1, by lead aircraft frame 1, the frame 1 top fixedly positioning frame 2 of cable wire suspension device 4, one end is hingedly fixed in the inclination belt feeder 7 on the frame 1, and steel wire erecting by overhang 4, oblique belt feeder lifting beam device 6 and pulley 5 that inclination belt feeder leaning angle is adjusted form.This kind carloader is in uphill process, because misoperation or automatically controlled part are malfunctioning, cable wire suspension device 4 can constantly rise by pulling inclination belt feeder 7, when rising to top limit position, the steel rope of steel wire erecting by overhang 4 can be broken, inclination belt feeder 7 will fall with acceleration due to gravity, and this situation all can not provide safety assurance for operating personal, inclination belt feeder and loading vehicles, even personal injury can occur.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of bag-pack cement loading machine power-free safety device of effective supply safety control is provided.
The technical solution of the utility model is:
A kind of bag-pack cement loading machine power-free safety device, it is characterized in that: the lead aircraft frame front end at carloader is movably installed with the hook that its hook portion can be hooked the carloader lifting beam device just, the top of this hook is connected with cylindrical rod, described cylindrical rod passes the stay bearing plate on the connection gusset that is welded on the carloader positioning frame, and the cylindrical rod cover between stay bearing plate and hook has coil tension spring.
On the described cylindrical rod trip ring is installed, coil tension spring is enclosed within on the cylindrical rod between trip ring and the stay bearing plate.
The end of described cylindrical rod is equipped with nut.
Described cylindrical rod cooperates with interporal lacuna on the stay bearing plate, and has higher right alignment.
Described hook is installed in lead aircraft frame front end by the axle connection mode.
Described axle connection mode refers to that axle is through in this hole in the perforate of lead aircraft frame front end.
Perforate free-running fit on described axle and the frame.
The safety device of bag-pack cement loading machine of the present utility model takes full advantage of the principle of balancing force, when misoperation or electric when out of control occurring, the inclination belt feeder will continue to rise to the top, until the steel rope of erecting by overhang is broken, after steel rope disconnects, the lifting beam device of inclination belt feeder will drop on the hook portion place of safety device hook below, and produce a downward gravity, hook is under the effect of axle, produce a bearing force upwards, thereby belt feeder is still on the safety device, frame can not fallen down, guaranteed the safety of the person and equipment.The utility model is simple in structure, and is economical and practical, and safety factor is high.
