It is connect with the basket body, the basket body is installed on close to the side of bridge, for the basket body to be suspended on
The guardrail of the bridge both sides is so that the movable type construction hanging basket moves freely when constructing on the guardrail.The program is led to
It crosses on the guardrail that hanging basket is arranged on to bridge railing both sides, solves in the prior art that personnel's handling appliance is bulky, structure bulky
The problem of.But operating personnel help object because not climbing, cause operating personnel that can only jump into when entering hanging basket from bridge
In hanging basket.Operating personnel are caused during hanging basket is jumped into, there are problems that the security risk fallen from bridge.
Utility model content
The purpose of this utility model is to provide a kind of bridge construction fall arrest devices, are resulted in solving the prior art
There is the security risk fallen from bridge during hanging basket is jumped into operating personnel.
In order to achieve the above object, the base case of the utility model provides a kind of bridge construction fall arrest device, packet
Include hanging basket, hanging basket is equipped with slidable connection in the first hanging portion of bridge guardrails of both sides and the second hanging portion, further includes pulling
Part and connecting cylinder, between the first hanging portion and the second hanging portion, drawing article one end is fixed with the first hanging portion to be connected drawing article
It connects, the other end of drawing article has external screw thread, and connecting cylinder is slidably connected on the guardrail of bridge, close to drawing article one in connecting cylinder
End is equipped with the internal thread with the external screw thread cooperation on drawing article, is equipped with several lozenges close to drawing article one end in connecting cylinder,
Drawing article is equipped with several and matched wedge block of lozenges close to connecting cylinder side, and wedge block is made of elastic component, on connecting cylinder
It is fixed with and climbs handrail.
The principle of this base case is：For operating personnel when entering hanging basket, handrail is climbed in rotation rotates connecting cylinder, connects
During cylinder rotation, the external screw thread cooperation on the internal thread and drawing article inside connecting cylinder drives connecting cylinder to be moved to drawing article, connection
During cylinder is mobile, wedge block is relatively moved with lozenges, so as to be compacted wedge block.Because wedge block is elasticity
Part, wedge block deform during being compacted, and Bridge guardrail is held tightly, so as to which connecting cylinder to be fixed on to the guardrail of bridge
On, and then make to climb handrail and fix.At this point, operating personnel help and climb handrail and enter in hanging basket, avoid in a manner of jump into hanging basket
In caused by security risk.In addition, when wedge block holds Bridge guardrail tightly, hanging basket is made not move, so as to avoid blowing
When hanging basket is blown, influence operating personnel work.
The advantageous effect of this base case is：1. the present apparatus can avoid operating personnel from being caused during jumping into hanging basket
The problem of security risk fallen from bridge.
2. hanging basket is blown when can avoid blowing, influence operating personnel's work.
3. present apparatus result is simple, easily operated.
Prioritization scheme one：Guide cylinder is further included, guide cylinder is slidably connected on the guardrail of bridge, and guide cylinder is fixed on second
On hanging portion, connecting cylinder is slidably connected on guide cylinder.The setting of guide cylinder makes connecting cylinder more steady when moving, so as to make
Internal and external threads easily coordinate, member people's operation easy to operation.
Prioritization scheme two：Further including check lock lever, check lock lever one end, which is hinged on, climbs handrail close to the first hanging portion side, and first
Hanging portion top is equipped with card slot corresponding with another end position of check lock lever.Make to climb handrail position after check lock lever clamping card slot completely solid
Fixed, when preventing from personnel from helping climbing handrail and enter hanging basket, connecting cylinder reversing causes personnel to fall.
Prioritization scheme three：Connection sheet is further included, connection sheet one end is connect with drawing article, and the connection sheet other end connects with wedge block
It connects, connection sheet is made of spring steel.It is easily deformed because connection sheet cross-sectional area is small, reduces the connection of wedge block and drawing article
And it is easily deformed, is easier wedge block the guardrail side chain of bridge is tight.
Prioritization scheme four：The check lock lever is caught in the wedge shaped shape in one end of card slot.After check lock lever is caught in card slot, then in card slot
Corresponding wedge-shaped fixture block is inside squeezed into, makes structure more firm, personnel safety is further protected.
