Description
Technical field
The present invention relates to field of bridge construction, are a kind of bridge construction fall arrest devices particularly.
Background technique
When the two sides of bridge carry out the operations such as attachment installation, decoration, finishing, need installation personnel being hoisted to bridge
Side carries out construction operation, can not be from ground or the water surface by personnel since bridge floor height is higher, and not excessively high lifting setting
It is transported to bridge floor from bottom to top with crane system, lifting device have to be taken to carry out handling to personnel from top to bottom.
Wirerope is driven to move up and down along elevation of building by elevator in hoisting process, not due to outside environmental elements
Controllably, it being easy that wirerope is driven to swing when wind-force is larger, the frequency and range ratio that wirerope is swung at this time are big under normal circumstances,
As the abrasion of the increase wirerope of hunting frequency also can be relatively serious, it is less favorable for using safely.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of bridge construction fall arrest device.
To achieve the goals above, the present invention is to realize by the following technical solutions: a kind of bridge construction is fallen with anti-
Fall equipment, structure includes that hanging basket, rope sling, hoist are connected the crossbeam of two sides hoist with level, the rope sling be connected to
Auxiliary girder between hoist and hanging basket forms tripodia and is distributed fixed structure, and the hoist upper end is equipped with fishhook and hollow shaft,
It is internally provided with solid spacing tooth and reciprocal circuit in the hoist, the solid spacing tooth is closed to be formed with reciprocal circuit
One round fixed structure, the circle fixed structure are welded in hoist, and the inside of the circle fixed structure is installed with backswing
Part and tensioning wheel, the tensioning wheel are cooperated by the wirerope and discus of winding traction, two tensioning wheels and wirerope with
Discus combination backswing part collectively constitutes the traction mechanism of hoist.
As a further improvement of the present invention, the backswing part includes foot prop, center drum, directive wheel, fast pulley, described
Foot prop is equipped with idler wheel, and the bolt axle and deck of promising V-shaped structure are welded on the center drum, and the foot prop passes through welding
Deck and bolt axle be fixed on the drum of center, there are two the directive wheel is set.
As a further improvement of the present invention, the foot prop is concave-shaped structure, and raised both ends are living by idler wheel respectively
Dynamic cooperation is on fast pulley, and the appearance periphery clearance fit for the horizontal plane and fast pulley being recessed.
As a further improvement of the present invention, two perforation for reeving are opened up in the solid spacing tooth.
As a further improvement of the present invention, the fast pulley is equipped with the interior circuit being flexibly connected with idler wheel, the interior circuit
With fast pulley concentric.
As a further improvement of the present invention, the steel wire penetrating perforation is drawn by tensioning wheel along fast pulley circular groove
It is placed in rope sling to directive wheel.
As a further improvement of the present invention, the directive wheel is set to the bottom end of center drum and has passed through connecting rod and fixes,
Angle cooperates the fixation of hanging basket two sides between 60 ° -70 ° between the connecting rod.
As a further improvement of the present invention, the directive wheel activity is brushed in wind on reciprocal circuit in order to realize
With wirerope synchronous hunting, wirerope is avoided to be worn by swing.
As a further improvement of the present invention, it is separately installed with contact sensor at the both ends for realizing spacing tooth, when
When directive wheel touches contact sensor, the internal alarm system for starting contact sensor can realize safety alarm.
Compared with prior art, the invention has the following beneficial effects:
1, present invention improves over the internal structure of hoist, fast pulley is fixed between two tensioning wheels, and fast pulley is matched
In the swing generated under wirerope is acted on by wind-force, foot prop can be cooperated foot prop, center drum and the directive wheel of conjunction using idler wheel
Interior circuit along fast pulley periphery synchronous reciprocating swing, avoid mechanical structure conflict may wear to wirerope, to avoid
Hunting frequency is excessive and leads to the case where wearing disconnected rope.
2, the round fixed structure that the present invention is formed using solid spacing tooth and reciprocal circuit stablizes directive wheel in reciprocal ring
The sliding generated on road.
3, distance is 8cm between directive wheel of the present invention, which can reduce directive wheel at a distance from the solid spacing tooth in two sides,
So that hanging basket is swung in safe range, reality can be contradicted when directive wheel oscillating stroke is larger when wind-force is larger in construction environment
Heart spacing tooth, therefore people is reminded to stop construction operation.
4, present invention foot prop for fixing is concave-shaped structure, is connected to by deck and completes to fix on bolt axle, and
The idler wheel installed on foot prop cooperates on interior circuit, and between the horizontal plane and fast pulley of foot prop there are gap can meet foot
Friction problem is not had when frame synchronous hunting.
5, for the present invention in the case where static wind-force is small, two directive wheels are in vertical straight line state, and directive wheel cooperates
Reciprocal circuit can meet and used under different wind direction environment.
