Description
Technical field
The present invention relates to a kind of deck unit erection gantries with automatic aligning pressure-bearing shearing resistance.
Background technique
Deck unit erection gantry is a kind of suspension bridge construction special equipment, and working method is provided across two main push-towing ropes of suspension bridge
On, the girder steel under bridge is promoted, is installed, currently, deck unit erection gantry have been widely used in the construction of Chinese large-sized suspension bridge.
As China's deck unit erection gantry designing technique and construction technology are more and more mature, under the premise of meeting construction feasibility, reliability,
Construction party requires the convenience that deck unit erection gantry operates also higher and higher.
It is general on deck unit erection gantry that all there is pressure-bearing shearing resistance system, pressure-bearing shearing-resistance blocks are loaded on to the lower section of end carriage, when cable load is hung
Before machine lifting, pressure-bearing shearing-resistance blocks need to be pressed on the main push-towing rope in front of cord clip, and by the rear end of pressure-bearing shearing-resistance blocks and cord clip
On the one hand on the other hand front end fitting, the main push-towing rope gradient is caused by pressure-bearing shearing-resistance blocks by loop wheel machine weight transfer to main push-towing rope
Sliding force be transferred on main push-towing rope cord clip.Since the position that deck unit erection gantry is stood when every section of girder steel is promoted is different, to guarantee
The rear end of pressure-bearing shearing-resistance blocks is bonded with the front end of cord clip, need to often adjust front-rear position of the pressure-bearing shearing-resistance blocks on end carriage.
And the mode that pressure-bearing shearing-resistance blocks and end carriage bottom plate are often connected by screw bolts by previous deck unit erection gantry, pressure-bearing shearing-resistance blocks are adjusted every time
When position, it is both needed to remove multiple bolts, pressure-bearing shearing-resistance blocks is shifted, are positioned, then re-tighten bolt, operating procedure is numerous
It is trivial.And due to sliding force need to by multiple bolt uniform forces, bolt interporal lacuna design value generally no more than 0.5mm,
The requirement of bolt hole aligning accuracy is very high, this just brings bigger inconvenience to positioning process.To sum up, the pressure-bearing being connected by screw bolts
Shearing-resistance blocks can bring very big difficulty to the operation of field worker, and have certain shadow to the construction efficiency of deck unit erection gantry
It rings.
Summary of the invention
Its purpose of the invention, which is that, provides a kind of deck unit erection gantry with automatic aligning pressure-bearing shearing resistance, solves tradition and rises
Positioning, problem difficult to install when heavy-duty machine pressure-bearing shearing-resistance blocks switching position, with easy to operate, mode of transfer force is reliable, work effect
The high feature of rate.
It adopts the technical scheme that achieve the above object, a kind of deck unit erection gantry with automatic aligning pressure-bearing shearing resistance,
Including the suspender connecting with end carriage, suspender lower end is fixed with heavy mail, is equipped with cord clip on the downside of the end carriage both ends, end carriage lower end is also
Equipped with multiple pressure-bearing shearing-resistance blocks, the pressure-bearing shearing-resistance blocks include top plate, and top plate lower end is fixed with bottom plate, and bottom plate lower end is equipped with master
Cable, main push-towing rope are fixed on the lower end of bottom plate through cord clip, and 4 corners on top plate upper surface are equipped with anti-hook, go back on top plate upper surface
It is fixed with pin shaft, the end carriage bottom end face is equipped with end carriage bottom plate, and end carriage bottom plate is equipped with multiple rows of pin corresponding with pin shaft
Axis hole.
Beneficial effect
The present invention has the following advantages that compared with prior art.
It is an advantage of the invention that solving in the bolt fixing method between traditional pressure-bearing shearing-resistance blocks and end carriage, between bolt hole
Gap is small, positioning, difficult to install, and the problem of need to repeatedly tighten bolt, have it is easy to operate, the advantages of improving work efficiency.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawing.
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is part-structure side view of the invention；
Fig. 3 is the partial structure diagram of pressure-bearing shearing-resistance blocks in the present invention；
Fig. 4 is the structural schematic diagram in the present invention between pressure-bearing shearing-resistance blocks and main push-towing rope.
Specific embodiment
With reference to the accompanying drawing, the present invention is further illustrated.
A kind of deck unit erection gantry with automatic aligning pressure-bearing shearing resistance, including the suspender 4 connecting with end carriage 1,4 lower end of suspender is solid
Surely there is heavy mail 5, as Figure 1-Figure 4, be equipped with cord clip 3 on the downside of 1 both ends of end carriage, 1 lower end of end carriage is additionally provided with multiple pressure-bearings
Shearing-resistance blocks 2, the pressure-bearing shearing-resistance blocks 2 include top plate 10, and 10 lower end of top plate is fixed with bottom plate 11, and 11 lower end of bottom plate is equipped with main push-towing rope
12, main push-towing rope 12 is fixed on the lower end of bottom plate 11 through cord clip 3, and 4 corners on 10 upper surface of top plate are equipped with anti-hook 9, top plate 10
Be further fixed on pin shaft 8 on upper surface, 1 bottom end face of end carriage is equipped with end carriage bottom plate 7, end carriage bottom plate 7 be equipped with it is multiple rows of with
The corresponding pin shaft hole 6 of pin shaft 8.
The pressure-bearing shearing-resistance blocks 2 are 3, and are evenly distributed between 2 cord clips 3.
The top of the pin shaft 8 is pyramidal structure, and pin shaft 8 is 4, and is fixed on the middle position of 10 upper surface of top plate,
Pin shaft hole 6 on corresponding end carriage bottom plate 7 is more than the amount of pin shaft 8.
The contact surface of the bottom plate 11 and main push-towing rope 12 is arc structure, to adapt to the shape of main push-towing rope 12.
In the present invention, including 1 end carriage, 1,3 pressure-bearing shearing-resistance blocks 2, pressure-bearing shearing-resistance blocks 2 be installed on 1 lower section of end carriage before,
In, rear three positions, the pressure-bearing shearing-resistance blocks 2 include that bottom plate 11,10,4, top plate pin shaft 8,4 instead hook 9, are set below bottom plate 11
For arc structure, to adapt to the shape of main push-towing rope 12 on suspension bridge, bottom plate 11 is fixedly arranged above top plate 10, leans on centre above top plate 10
Position is fixed with 4 pin shafts 8, and the top of pin shaft 8 is pyramidal structure, and the position at 4 angles is leaned on to be fixed with 4 instead above top plate 10
9 are hooked, the end carriage bottom plate 7 of 1 bottom of end carriage is equipped with multiple rows of pin shaft hole 6, for matching with the pin shaft 8 in pressure-bearing shearing-resistance blocks 3
It closes.
Due to needing demolition, installation 10 or more bolts when existing pressure-bearing shear resistance system changes position every time, and bolt hole fills
With precision within 0.5mm, assembly difficulty is very big, and traditional bolted pressure-bearing shear resistance system is changed to pin shaft by the present invention
The pressure-bearing shearing-resistance blocks 2 of formula connection, and special structure is used, weight when need to only be pushed using deck unit erection gantry when changing position every time
Power automatic aligning is not required to demolition, installation bolt, have it is easy to operate, the characteristics of improving work efficiency.
