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.
Utility model content
Its purpose of the utility model, which is that, provides a kind of deck unit erection gantry device with automatic aligning pressure-bearing shearing resistance, solves
Positioning, problem difficult to install when conventional hoist pressure-bearing shearing-resistance blocks switching position, have easy to operate, mode of transfer force can
It leans on, the characteristics of work efficiency is high.
It adopts the technical scheme that achieve the above object, a kind of deck unit erection gantry dress with automatic aligning pressure-bearing shearing resistance
It sets, including the suspender connecting with end carriage, suspender lower end is fixed with heavy mail, cord clip is equipped on the downside of the end carriage both ends, under end carriage
End is additionally provided with multiple pressure-bearing shearing-resistance blocks, and 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
Main push-towing rope, 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, on top plate upper surface
It is further fixed on 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 corresponding with pin shaft
Pin shaft hole.
Beneficial effect
The utility model has the following advantages that compared with prior art.
The utility model has the advantages that solving in the bolt fixing method between traditional pressure-bearing shearing-resistance blocks and end carriage, bolt
Interporal lacuna is small, positioning, difficult to install, and the problem of need to repeatedly tighten bolt, has easy to operate, and what is improved work efficiency is excellent
Point.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the part-structure side view of the utility model；
Fig. 3 is the partial structure diagram of pressure-bearing shearing-resistance blocks in the utility model；
Fig. 4 is the structural schematic diagram in the utility model between pressure-bearing shearing-resistance blocks and main push-towing rope.
Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
A kind of deck unit erection gantry device with automatic aligning pressure-bearing shearing resistance, including the suspender 4 being connect with end carriage 1, under suspender 4
End is fixed with heavy mail 5, as Figure 1-Figure 4, is 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-bearing 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 master
Cable 12, main push-towing rope 12 are 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
Pin shaft 8 is further fixed on 10 upper surfaces, 1 bottom end face of end carriage is equipped with end carriage bottom plate 7, and end carriage bottom plate 7 is equipped with multiple rows of
Pin shaft hole 6 corresponding with 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.
