Abstract
The utility model relates to an elevating mechanism of a boring tower cage. A cantilever beam is fixed at the top of a boring tower, the upper part of the external end of the cantilever beam is fixed on the boring tower roof via a lifting rope, and the lower part of the external end of the cantilever beam fixes the upper end of a balance weight guiding rope, the lower end of the balance weight guiding rope is fixed to a fixing rod, the fixing rod is inserted on the base of the boring tower, a left swinging ring and a right swinging ring are respectively fixed at the two ends of the cantilever beam, hooks are respectively hooked on the left and right swinging rings, a pulley is fixed on the hooks via a bearing, a steel wire rope is wound on the pulley, one end of the steel wire rope is fixed to the balance weight, the other end of the steel wire rope is fixed to the cage, a sliding ring is fixed on the balance weight, the sliding ring is sleeved on the balance weight guiding rope, and the cage is connected with the inclined guide rail of the boring tower via a cage guiding rope. The elevating mechanism is less in area occupation, convenient in detachment, safe and reliable.
Description
Technical field
The utility model relates to a kind of lifting mechanism of boring tower cage.
Background technology
In the pitshaft freezing hole construction process, cage is the requisite device that the operating personnel carries out high-rise working, its Reliability Assurance operating personnel's personal safety and engineering smooth construction, but traditional cage is installed and has been had following several deficiencies: 1, occupied ground is large; 2, the labour power of paying in the time of about the personnel is strong; Needing a large amount of manpowers to carry out falling mound when 3, moving tower after the Completion of Drilling Hole removes, installs; 4, cage steel rope and the friction of boring tower flat-topped ridge cause steel rope and flat-topped ridge to wear and tear simultaneously in the time of about the personnel, have also produced potential safety hazard in the time of the waste material; 5, personnel's falling mound and falling mound guide steel wire rope when tower is worked causes a hidden trouble to passing worker's personal safety easily.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of boring tower cage lifting mechanism, and its occupied ground is little, and convenient disassembly is safe and reliable.
The technical scheme in the invention for solving the technical problem is: the top cantilever mounted beam of boring tower, the top of the outer terminal of cantilever beam is fixed on the described boring tower top by lifting rope, the bottom of the outer terminal of cantilever beam is the upper end of falling mound guide rope fixedly, lower end and the hold-down bars of falling mound guide rope are fixed, and hold-down bars is inserted on the base of described boring tower; The two ends of described cantilever beam are fixing left and right sides suspension ring respectively, minute hang with hook on the suspension ring of the left and right sides, pass through the bearing dead sheave on the hook, are wound with steel rope on the pulley, and an end and the falling mound of steel rope are fixed, and the other end and cage are fixed; Be fixed with slip ring on the described falling mound, slip ring sleeve is on described falling mound guide rope; Described cage links to each other with the inclined guide rails of boring tower by the cage guide rope.
The utlity model has following advantages: 1, the falling mound guide rope is basic parallel with the boring tower edge, and it is large to have solved occupied ground, the shortcoming of length of steel rope.2, falling mound guide rope angle becomes large, has reduced the friction force of guide rope and falling mound pulley, has reduced the up and down labour intensity of boring tower of personnel.When 3, the boring tower pore-forming moves tower, solved installation and the dismounting of personnel to the falling mound guide rope, reduced the labour intensity of removing and installing and saved a large amount of installations, dismounting time.4, because the top steel pipe has certain distance in boring tower, guaranteed to connect the steel rope of cage and the distance of boring tower flat-topped ridge, saved material, eliminated again potential safety hazard.5, cage and falling mound guide steel wire rope be at a distance of nearer, makees an easy guardrail and just can prevent simultaneously damage personnel's the accident generation of cage and falling mound, avoided traditional not firm danger that causes falling mound to hurt sb.'s feelings of out boxing falling mound guide rope earth anchor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model scheme drawing.
The specific embodiment
As shown in Figure 1, the top cantilever mounted beam 3 of boring tower 1, the top of the outer terminal of cantilever beam 3 is fixed on described boring tower 1 top by lifting rope 2, the bottom of the outer terminal of cantilever beam 3 is the upper end of falling mound guide rope 7 fixedly, the lower end of falling mound guide rope 7 and hold-down bars 10 are fixing, and hold-down bars 10 is inserted on the base of described boring tower 1; The two ends of described cantilever beam 3 are fixing left and right sides suspension ring respectively, minute hang with hook 4 on the suspension ring of the left and right sides, by the bearing dead sheave, are wound with steel rope 6 on the pulley on the hook 4, and an end of steel rope 6 is fixing with falling mound 5, and the other end and cage 9 are fixed; Be fixed with slip ring on the described falling mound 5, slip ring sleeve is on described falling mound guide rope 7; Described cage 9 links to each other with the inclined guide rails of boring tower 1 by cage guide rope 8.
For convenient disassembly, described cantilever beam 3 is bolted with boring tower 1.
