Description
Technical field
The present invention is a kind of overhead job platform of bridge construction, belongs to bridge construction with overhead job platform field.
Background technology
So-called high-rise working refers to the operation that eminence of the people on the basis of certain position is carried out.Standard GB/T/T 3608-
2008《High-rise working is classified》Regulation：" all eminences for (containing 2m) more than height of fall reference plane 2m and being possible to fall are made
Industry, referred to as high-rise working." according to this regulation, the scope that high-rise working is related in construction industry is quite extensive.
In building during operation, if being operated on more than 2m shelf, as high-rise working.
When altitude effect is often to use to arrive aerial work platform, especially bridge building operations, the high construction dimension of height
Repair that difficulty is big, the overhead job platform then to arise at the historic moment shows particularly significant, excessive height during due to construction, existing safety
Problem can not be ignored, although being equipped with safety belt, when careless generation personnel fall, often simply be hung in personnel aerial etc.
Wait to rescue, can not voluntarily rise, if rescue has huge potential safety hazard not in time.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the present invention to provide a kind of bridge construction with overhead job platform, with

Safety belt of the present invention is high-rise working type, is after preventing high-rise working personnel from falling or falling
By the Individual protection equitment of operating personnel's safety suspension.According to the difference of use condition, following 3 class, railing operation can be divided into
Safety belt, human body is bundled near fixed structure by the rope or belt being centered around in fixation construct, makes operating personnel
Both hands can carry out other operation safety belt；Region limits safety belt, to limit the scope of activities of operating personnel, avoids
It reaches the safety belt in the region that may fall；Fall suspension safety belt, will when high-rise working or the personnel of ascending a height fall
The safety belt of operating personnel's suspension.
Pulley of the present invention, typically can be around the circle wheel that central shaft rotates in mechanics.In the circle of circle wheel
Side face has groove, rope is wound in into groove, firmly the either end at rope for traction both ends, then the friction between rope and circle wheel
Power can promote circle wheel to be rotated around central shaft.Pulley is actually lever deforming, can rotating.The main function of pulley is to lead
Draw load, change force direction, transimission power etc..The machinery that multiple pulleys collectively constitute is referred to as " assembly pulley ", or " compound cunning
Wheel ".The mechanical advantage of assembly pulley is larger, can pull heavier load.Pulley can also turn into the group of Chain conveyer or V belt translation
Part, power is transferred to another rotary shaft from a rotary shaft.
Whether moved by the position of pulley center axle, pulley can be divided into " fixed pulley ", " movable pulley "；The center of fixed pulley
Axle is fixed, and the central shaft of movable pulley can move, each have their own Pros and Cons.And fixed pulley and running block are mounted in
Assembly pulley is may make up together, and assembly pulley is not only laborsaving but also can change the direction of power.
In bridge construction with overhead job platform in use, personnel are in higher position, once fall accidentally, fastening now
Ined succession personnel's tenesmus in the safety belt of personnel's loins, safety rope 101 now 105 surpasses in operating desk 11 vertically downward, by diving board
Portion direction pressure is gone, and the second metal contact wires 1065 then tensed originally loosen drawing and slided along the 5th pulley 1064 and the 6th
Wheel 1066 slide, due to without the second metal contact wires 1065 drawing limitation, recover spring 1042 acting force of the spring from
Right-to-left is ejected, and push pedal 1043 is released along slide rail 1045, and push pedal 1043 mutually agrees with gravity block 1024, then gravity
Block 1024 is pushed out, and the first metal contact wires 1023 being connected with gravity block 1024 produce the power of drawing, by electric motor starting
Unlatching slider 1022 pull down, open motor 102；After motor 102 is opened, safety rope roll 1020 starts to rotate, and is pacified
The pulling force of full rope roll 1020, safety rope 101 is multiple to be wound on safety rope roll 102, the personnel then to drop immediately with
Safety rope 101 to be raised above, avoid continuing to drop, until when personnel climb back operating desk 11, the no longer vertical court of safety rope 101
Under, then diving board 105 is restricted the power ejection of spring 1050 and returns to initial position, by the second metal contact wires 1065 towards outside
Drawing, then push pedal 1043 are set back by the drawing of the second metal contact wires 1065, then open slider 1022 and also recover
To original position, motor 102 is closed, by safety belt protection mechanism with reach automatically by drop personnel's pull-up purpose, in practical bridge
If beam construction, in use, when fall event occurring accidentally, automatically can be risen personnel with safety belt with overhead job platform,
Save oneself in time.
The present invention solves the problems, such as it is that the overhead job platform of bridge construction can not possess when fall event occurs, can
Automatically rise the function of being saved oneself, due to construction when excessive height, existing safety problem can not be ignored, although being equipped with pacifying
Full band, but generation personnel are when falling accidentally, are often simply hung in personnel and wait for rescue in the air, can not voluntarily rise, if rescuing
Help not in time and huge potential safety hazard be present, being combined with each other by above-mentioned part of the invention, it is high to realize practical bridge construction
If personnel can be risen, saved oneself in time in use, when fall event occurring accidentally by frame job platform with safety belt automatically,
The situation for avoiding rescuing not in time occurs, and improves safety in utilization.
In embodiments of the invention 1, the push pedal 10463 is plastic material；
In embodiments of the invention 2, the push pedal 10463 is metal material；
| Embodiment 1 | Embodiment 2 | |
| Weight | Gently | Weight |
| Cost | It is low | It is higher |
In summary, when the push pedal 10463 of the present invention is plastic material, use weight of the invention is lighter, is easy to push away
Dynamic, cost is relatively low, is easy to promote, and using effect reaches optimal.
