Description
Technical field
The utility model belongs to the method or equipment technical field for being exclusively used in setting up or assembling bridge.
Background technology
Bridge, refers to and is erected in rivers,lakes and seas, the building for making traffic etc. smoothly to pass through, referred to as bridge.Bridge one
As be made up of superstructure, substructure and attached structure, superstructure refers mainly to bridge span structure and support system；Lower junction
Structure includes abutment, bridge pier and basis；Attached structure then refers to transition slab at bridge head, truncated cone banking, shore protection, training works etc..In bridge
Build and maintenance during, can usually use many Architectural Equipments, hanging basket is exactly one kind therein, nacelle device quality it is good
The bad life security and building progress for directly affecting builder.In the hanging basket of existing bridge construction, usually occur,
Hanging basket low intensity, operation is unstable, and inclination, the phenomenon slid occur during long-term use, occurs when serious
The phenomenon dropped, has a strong impact on the life security of operating personnel.
In order to ensure the life security of operating personnel, there is the patent that a notification number is CN205205690U in the prior art
File, discloses a kind of nacelle device of bridge construction, with hanging basket body, and the upper end of the hanging basket body is connected by steel wire rope
Multigroup running block is connect, the steel wire penetrating running block connects the first fixed pulley group on top, the first fixed pulley group
The other end of steel wire rope connect the second fixed pulley group, the other end connection of the steel wire rope of the second fixed pulley group multigroup is batched
Machine.
The concrete operations flow of the nacelle device of the bridge construction is:When operating personnel need to move up and down hanging basket body
When, it is only necessary to control coiling machine to realize the rise and fall of hanging basket body, due to there are two strands on the upper surface of hanging basket body
Steel wire rope is around being connected on a movable pulley.So hanging basket body is very steady during operation, additional first is added calmly sliding
The transmission of wheel group, can make it that this running body of hanging basket is more steady, improve safety coefficient.
But said apparatus is in use, hanging basket is directly contacted with bridge, then in long-term raising and lowering mistake
Hanging basket is highly prone to abrasion in journey, or even can damage hanging basket, causes operating personnel to come to harm.
Utility model content
The purpose of this utility model is to provide a kind of nacelle device of bridge construction, it is to avoid hanging basket is worn, and improves
The security of operating personnel.
In order to achieve the above object, base case of the present utility model provides a kind of nacelle device of bridge construction, including
It is provided with the top of hanging basket, the hanging basket on steel wire rope, steel wire rope and is connected with the first fixed pulley group and the second fixed pulley group, second in turn
The side of fixed pulley group is provided with coiling machine, and steel wire rope is connected with coiling machine, and the is provided between the first fixed pulley group and hanging basket
Three fixed pulley groups, the 3rd fixed pulley group is located on bridge；The hanging basket is provided with groove, groove with the close side of bridge and is hinged

The principle of this base case is：In use, coiling machine is fixed on bridge, operating personnel enter hanging basket, so
After start coiling machine, begin paying out steel wire rope, so that hanging basket is slided along bridge, now operating personnel start to rotate screw thread
Bar, threaded rod is screwed out from cylinder, while pulling threaded rod, makes threaded rod drive support bar to stretch, so that support bar will
Threaded rod is pushed against, and now support bar, threaded rod and groove directly form the rock-steady structure of triangle, improves the smooth of hanging basket movement
Property, roller is pushed out groove with the final roller of the rotation of threaded rod, and roller directly offsets with bridge surface, and roller is in bridge
Surface scrolls realize that hanging basket is moved, and hanging basket is not contacted directly with bridge during hanging basket is moved.
When hanging basket is slid to operating position, opposite direction rotates threaded rod to operating personnel again, and threaded rod is revolved again
Enter cylinder, while cylinder is pushed back into inside grooves, now hanging basket is contacted with bridge, the skid resistant course on hanging basket and bridge directly against
Close, make hanging basket keep being relatively fixed with bridge, now operating personnel start bridge floor work, after operating personnel complete work, behaviour
Make personnel and just directly screw out threaded rod release roller again according to aforesaid way, roller protrudes again from groove to be contacted with bridge,
Hanging basket is pulled on into bridge again.
The beneficial effect of this base case is：Roller and skid resistant course are set in this programme roller is contacted with bridge so that
Slide up and down, it is to avoid hanging basket is directly contacted with bridge in motion process with bridge, so that the service life of hanging basket is improved,
The degree of wear that hanging basket is subject to during raising and lowering is reduced, so as to avoid hanging basket from being worn, while using anti-skidding
Layer is relatively fixed with bridge, and when the operating personnel is worked, hanging basket will not shake, the peace that raising operating personnel work in hanging basket
Quan Xing,
Scheme two：Scheme is preferred based on this, and the hanging basket bottom is provided with bearing.
After operating personnel complete work, hanging basket is placed on bridge surface, hanging basket bottom is not contacted directly with bridge,
Avoid hanging basket bottom from being worn, improve the service life of hanging basket.
Scheme three：This is preferred for scheme two, and the hanging basket side is hinged with the door-plate for being available for personnel to come in and go out.
Operating personnel just push door-plate open after completing work, then walk out, are jumped out compared to operating personnel from hanging basket from hanging basket,
Operating personnel, which directly walk out, more to be facilitated.
Scheme four：This is preferred for scheme three, and the steel wire rope at the top of the hanging basket is two strands, and two strand steel wire ropes are fixed along the 3rd
The direction that assembly pulley is rotated is around being connected in the 3rd fixed pulley group.
Two strand steel wire ropes are separately positioned on the both sides at the top of hanging basket, advantageously keep balancing in hanging basket, it is to avoid hanging basket exists
Tilted in the course of work, so as to improve the stability of hanging basket work.
Scheme five：This is preferred for scheme four, and the first fixed pulley group bottom is provided with mounting bracket.
First fixed pulley group is arranged on bridge by mounting bracket, easier for installation.
Scheme six：This is preferred for scheme five, and the coiling machine is connected with drive motor.
Worked using drive motor coiling machine, realize the movement of steel wire rope, so that steel wire rope drives hanging basket to rise
And decline, make hanging basket motion quicker.
