Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Present embodiment discloses a kind of rolling-mill housing from discharging method, comprising the following steps:
1) as shown in figure 3, driving into the transport vehicle 1 for loading organic frame 3 to drop off location, and on the ground 4 of 1 two sides of transport vehicle
Dumping device 2 is placed, dumping device 2 includes hydraulic jack 22；
It is to be appreciated that dumping device 2 can be arranged before transport vehicle 1 drives into drop off location, arrangement as shown in Fig. 2,
It can also carry out the arrangement of dumping device 2 again after transport vehicle 1 drives into drop off location, the position of dumping device 2 is root
It is determined according to the size and supporting plane of rolling-mill housing 3.
In a wherein embodiment, as shown in Figure 1, the dumping device 2 for being located at 1 two sides of transport vehicle is arranged symmetrically,
Stationarity when better ensuring that rack 3 is jacked.
Further, two dumping devices 2 are at least arranged in 1 the same side of transport vehicle, to guarantee the steady jacking of rack 3.
Preferably, as shown in Figure 1, two dumping devices 2 are respectively arranged in 1 the same side of transport vehicle.
Further, the summation positioned at the arrangement spacing of the dumping device 2 of 1 the same side of transport vehicle is not less than 3 length of rack
0.5 times, if such as 1 the same side of transport vehicle be sequentially arranged four dumping devices 2, respectively A1, A2, A3 and A4, A1 and A2 it
Between spacing be L1, spacing between A2 and A3 is L2, and the spacing between A3 and A4 is L3, in addition defines the length of rack 3
For L, then L1, L2 and L3 and be not less than 0.5L.The arrangement can greatly improve the jacking of rack 3 or fall the steady of process after rise
It is qualitative.
2) as shown in figure 3, the piston rod of driving all hydraulic jack 22 stretches out, until the top of piston rod and rack 3
Bottom surface be in contact, then stop driving all hydraulic jack 22, until rack 3 is in steady state；
It should be understood that when arranging hydraulic jack 22, since the width of rack 3 is typically larger than the width of transport vehicle 1
So that hydraulic jack 22 is located at the sections bottom that 3 edge of rack exceeds transport vehicle 1, and when in order to piston rod stretching, top
It is convenient to be in contact with 3 bottom surface of rack.
Further, when the top of all piston rods and the bottom surface of rack 3 are in contact, the top surface of all piston rods is in same
On one horizontal plane, to better ensure that subsequent stability rack 3 rise and fallen after rise.
3) as shown in figure 4, the piston rod of all hydraulic jack 22 is driven to continue synchronous stretch out and jack up rack 3 simultaneously,
Piston rod remains at the uniform velocity when stretching out, until rack 3 and transport vehicle 1 are separated；
In a wherein embodiment, when rack 3 and transport vehicle 1 are separated, between 3 bottom surface nadir of rack and transport vehicle 1
Spacing be 30~50mm, namely disengaging gap between rack 3 and the transportation surface of transport vehicle 1 is made to be 30~50mm, should between
Gap can preferably guarantee that transport vehicle 1 is smoothly driven out to drop off location, without interfering with rack 1.
4) transport vehicle 1 is sailed out of into drop off location；
5) as shown in figure 5, the piston rod of driving all hydraulic jack 22 bounces back simultaneously and falls rack 3 to setting height after rise,
To complete unloading for rack 3.
In a wherein embodiment, as shown in fig. 6, dumping device 2 further includes unloading kickstand 21,21 He of kickstand is unloaded
Hydraulic jack 22 is connected.At this time in step 5), the piston rod of all hydraulic jack 22 can be bounced back to mutually to be taken off with rack 3
From, and 3 bottom end of rack is made to drop down onto the top surface for unloading kickstand 21 completely so that piston rod top end no longer stress, completely by
21 framework for support 3 of kickstand is unloaded, prevents rack 3 from reducing smoothness because of the oil pressure of hydraulic jack 22 shakiness, while can also have
Effect protection hydraulic jack 22.
Unloading kickstand 21 can also be used structure shown in Fig. 7.
In a wherein embodiment, unloading kickstand 21 is triangular supports, and stability is good.
In a wherein embodiment, the top surface of the piston rod of hydraulic jack 22 is pasted with rubber pad, is subtracted with playing
The effect shaken and prevent 3 surface of rack from wearing.
The rolling-mill housing of the present embodiment is easy to operate from discharging method, effectively reduces construction cost, and it is special both to have saved lease
The expense that large size driving generates, also saves the expense being transformed because using large-scale drive a vehicle to workshop or workshop；Also significantly
It improves and unloads vehicle speed and efficiency of unloading, and is versatile, it is easy for construction.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.Those skilled in the art's made equivalent substitute or transformation on the basis of the present invention, in the present invention
Protection scope within.Protection scope of the present invention is subject to claims.
