Description
Technical field
The utility model relates to a kind of safety device of building tower crane manned lift hanging basket, and particularly a kind of structure of building tower crane manned lift safety device of cableway basket, belongs to safety facilities technical field.
Background technology
Building tower crane is a kind of weight-lifting equipment the most frequently used on building ground, and common tower crane operative employee will climb up from ground the handling of tower top operational tower and turn, thereby this is an aloft work and is with dangerous work.Existing tower crane lacks the facility of protection tower crane operative employee person safety; especially climbing to the process of tower top, tower crane operative employee not only expends muscle power, and the safety factor of free-hand climbing is lower; just in case ascending stair corrosion or tower crane working are short of physical strength, hardly imaginable serious consequence will be caused.For improving tower crane operative employee's service conditions; and the protection facility that tightens security; the accident that prevents is in possible trouble; the utility model patent of declaring on the same day with the utility model provides a kind of building tower crane Worker carrying basket; it drives Worker carrying basket lifting by winch; make tower crane operative employee under the condition without free-hand climbing, realize freely upper and lower object and improved safety factor.But the security risk that hanging basket may exist in operational process should be predicted and should not underestimate, such as: being connected between lifting rope and hanging basket comes off; The fracture of lifting rope etc.Therefore, design the key that a kind of safety device matching is with it building tower crane Worker carrying basket safety work.
Summary of the invention
The utility model will be guaranteed the safe operation perfectly safely of building tower crane Worker carrying basket exactly, and a kind of safety device of building tower crane manned lift hanging basket is provided.
To achieve these goals, the utility model Bian gets following technical scheme and implements: a kind of safety device of building tower crane manned lift hanging basket, formed by Worker carrying basket, two lifting guide pillars, some support rails, a suspention lever and torsion springs, many the rollers that Worker carrying basket is provided with by the outside side of hanging basket respectively two lifting guide pillars of obvolvent also can move along guide pillar is upper and lower, it is characterized in that:
The spacing distance horizontal welding of some described support rails taking spacing as 30cm～40cm is connected between two lifting guide pillars;
Described suspention lever one end connects lifting rope, and middle part forms fixed hinge with Worker carrying basket bottom, and hinge axes, with to be welded on support rail between two lifting guide pillars parallel, suspended the other end sensing support rail of lever in midair, and is provided with hook in termination portion;
The rotation axis of described fixed hinge is to the vertical distance of support rail in horizontal surface, and the rotation axis that is less than fixed hinge is provided with the distance of hook end to suspention lever;
Described torsion spring is enclosed within outward on the rotation axis of fixed hinge, and suspention lever is subject to it to reverse the effect of reply power, and reverse restoring force the tangential direction of suspention lever and lifting rope point of connection with lift by crane rope to hang force direction contrary.
The utility model is by the fixed hinge forming between Worker carrying basket bottom and suspention lever middle part, make to be connected between the lifting rope of suspention lever one end and Worker carrying basket and form linking relationship, in the time that lifting rope imposes lifting force to suspention lever, suspention lever is made gyroscopic movement, drives Worker carrying basket to rise along two lifting guide pillars after being obstructed; And when lifting rope throw off suspention lever or lifting rope be pulled off and make Worker carrying basket glide time, suspention lever is done reversed turning motion under the restoring force effect of torsion spring, making to suspend in midair any one that this one end moment that lever is provided with hook drops between two lifting guide pillars supports on whippletree, stop Worker carrying basket to continue the effect of gliding thereby play, realize insurance object.
The utlity model has advantage reasonable in design, simple in structure, safe and applicable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in accompanying drawing 1,2,4, many rollers 5 that Worker carrying basket 1 is provided with by the outside side of hanging basket respectively two lifting guide pillars of obvolvent 2 also can move along lifting guide pillar 2 is upper and lower; The spacing distance horizontal welding taking spacing as 30cm～40cm of some support rails 6 is connected between two lifting guide pillars 2; Suspention lever 4 one end connect lifting rope 3, middle part forms fixed hinge with Worker carrying basket 1 bottom, hinge axes is with to be welded on support rail 6 between two lifting guide pillars 2 parallel, the other end of suspention lever 4 points to support rail 6, and be provided with hook 401 in termination portion, the rotation axis of above-mentioned fixed hinge is to the vertical distance of support rail 6 in horizontal surface, and the rotation axis that is less than fixed hinge is provided with the distance of hook 401 ends to suspention lever 4; As shown in Figure 4, torsion spring 7 is outer to be enclosed within on the axis of revolution 8 of fixed hinge, and suspention lever 4 is subject to it to reverse the effect of reply power, and reverse restoring force the tangential direction of suspention lever 4 and lifting rope 3 point of connection with lift by crane rope 3 to hang force direction contrary.
The utility model is by the fixed hinge forming between Worker carrying basket 1 bottom and suspention lever 4 middle parts, make to be connected between the lifting rope 3 of suspention lever 6 one end and Worker carrying basket 1 and form linking relationship, in the time that lifting rope 3 imposes lifting force to suspention lever 6, suspention lever 6 is made gyroscopic movement, drives Worker carrying basket 1 to rise along two lifting guide pillars 2 after being obstructed; As shown in accompanying drawing 3 and 5, when lifting rope 3 throws off that suspention levers 4 or lifting rope 3 are pulled off and when Worker carrying basket 1 is glided, suspention lever 4 is done reversed turning motion under the restoring force effect of torsion spring 7, making to suspend in midair any one that this one end moment that lever 4 is provided with hook 401 drops between two lifting guide pillars 2 supports on whippletree 6, stop Worker carrying basket 1 to continue the effect of gliding thereby play, realize insurance object.
