Abstract

The utility model provides a movable type automatic safety device, which can effectively ensure the safety of material lifting and personal in construction, and in the construction plays two obvious roles that when heavier articles are carried by a hanging scaffold to be conveyed to a construction floor, the barycenter is shifted to the edge of the hanging scaffold to generate overturning torque. The hanging scaffold is passed on a safety support frame to ensure the safety of the construction. When a winding engine is failed, a steel wire is broken, and the hanging scaffold rapidly slips downwards along a slide rail and touches the safety device, the hanging scaffold obtains reaction force, and is braked immediately, and the safety of the construction is ensured.

Description

Movable automatic safety device

The utility model is a kind of movable automatic safety device, in promoting all kinds of constructional materialss and member, can effectively guarantee safety in construction to the commonly used portal frame of building enterprise and well formula hoist, break building enterprise simultaneously and in building operations, mustn't go up people's construction safety standard to portal frame and well formula hoist, it has reliable degree of safety, guarantee the safety of lives and properties, execution conditions have been improved, the movable automatic safety device of the utility model, it is applicable to small and medium construction enterprise, in industry and civilian construction are constructed, in employed portal frame and the well formula hoist.

Current employed portal frame of small and medium construction enterprise and well formula hoist are from security standpoint, the problem that has 2 outstanding needs to solve, 1, when portal frame in operate as normal, hanging scaffold is loaded with weight or large-scale component, member transports the construction floor to from hanging scaffold, center of gravity moves on to the hanging scaffold edge, produce bigger tilting force distance, cause the derailing of hanging scaffold displacement or hanging scaffold easily, for fear of unsafe factor, employing is manually rolled bar power is passed on the scaffold, so promptly increases the labour, and (particularly many floors haul seems more outstanding) produces the unsafe factor of a work high above the ground again; 2, in case machinery is malfunctioning, the disconnected rope of steel wire, or pulley frame and head sheave breakage are malfunctioning, hanging scaffold directly land face from the high-altitude with the acceleration of gravity of approximate 9.8 meters of per second, and irresistible serious accident takes place at this point.

The purpose of this utility model is that a kind of reliable degree of safety that has will be provided, guarantee the movable automatic safety device of the security of the lives and property, it can effectively make portal frame and well formula hoist in building operations, guarantee the better effect of performance under the safe prerequisite, raise the efficiency, improve execution conditions, when portal frame in operate as normal, when hanging scaffold is loaded with weight or large-scale component and rises to needed construction floor, by transporting floor on the hanging scaffold to, center of gravity moves on to the hanging scaffold edge, produce bigger tilting force distance, at this moment the bar that rolls automatically that is provided with below by hanging scaffold passes on the emergency support, opposing tilting force distance, make hanging scaffold be in steadily normal duty, guarantee safe construction.

The purpose of this utility model provides a kind of portal frame and well formula hoist is under abnormal duty, can guarantee safe " movable automatic safety device ", in construction, in case hoist is malfunctioning, disconnected rope of steel wire or head sheave breakage are malfunctioning, hanging scaffold is out of control sharply to glide along slide rail acceleration of gravity, when running into safety device, gives by hanging scaffold a reaction force, make the mechanism on the hanging scaffold, block slide rail, hanging scaffold brakes immediately, does not directly land face, guarantees the security of the lives and property in the construction, because the utility model provides a kind of safety that can guarantee lives and properties in construction, so broken portal frame and well formula hoist mustn't be gone up people's construction safety standard in construction, given in the construction and provide convenience, thereby improved execution conditions.

Movable automatic safety device of the present utility model is made up of three parts: at first be to be welded in slide plate (13) by A-frame (4) upward to be fixed on needing on the position of steel portal frame (3) by set bolt (2), movable pressure pin (5) that can change 135 ° of weldering on slide plate, the hanging scaffold supporting stabilizing mechanism of being formed (1), it 2 is to be welded with the angle steel that tilts to (3) on the skeleton to roll bridge (8) below hanging scaffold (6), placing steel tubes is rolled bar (11), rolling bar two is welded with round steel resistance head (7) and forms and roll linkage, its 3, oval hanging scaffold locator card (15) is housed below hanging scaffold (6) and control pin (14) safety spring (16) draws the emergent automatic brake mechanism of forming in (17) and support (18).

The purpose of this utility model is finished as follows: when portal frame (3) operate as normal, hanging scaffold (6) rises to hanging scaffold supporting stabilizing mechanism (1) by wire rope (12), at this moment roll bar (11) automatically under the effect of A-frame (4) hypotenuse, outside rolling bridge (8), move, when rolling bar (11) movable pressure pin (5) held up, it is close to steel portal frame (3) along the gradient of rolling bridge (8) automatically under action of gravity to roll bar (11), wire rope (12) is transferred 15-20cm and is rolled bar (11) and fall on the A-frame (4), held hanging scaffold (6), at this moment can load and unload object, if not needing to stop herein wire rope (12) continue to promote and to roll bar (11) movable pressure pin (5) is lifted, when rolling bar (11) and exceed movable pressure pin (5) length, pressure pin (5) automatically resets under the effect of deadweight, when hanging scaffold (6) descends by hanging scaffold supporting stabilizing mechanism (1), roll bar (11) outwards displacement under the effect of movable pressure pin (5), by after roll bar (11) the deadweight effect automatically reset, thereby hanging scaffold (6) along slide rail (9) can freedom about, when the volume camera of portal frame (3) malfunctioning, disconnected rope of wire rope (12) or head sheave breakage cause that hanging scaffold (6) is out of control to glide rapidly along slide rail (9), the movable pressure pin (5) of running into hanging scaffold supporting stabilizing mechanism (1) at this moment rolls bar (11) and will roll bar (11) be bound to the termination of rolling bridge (8) under the quick reaction of movable pressure pin (5), run into pull bar (17), pull bar (17) pulls control pin (14) again, at this moment safety spring (16) plays a role hanging scaffold locator card (15) is strained, and the hanging scaffold locator card be Sui Yuan prejudicially, so blocking tighter and tighter in action of gravity can block inflexibly, the slide rail (9) of steel portal frame (3) is not put, and support (18) relatively firmly, so active force is very big, produce emergent self-actuating brake immediately, hanging scaffold (6) and contained personnel and material safety are not had suddenly.
