Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.It should be noted that in the absence of conflict, embodiment in the present invention and
Feature in embodiment can be combined with each other.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Referring to fig. 2 to Fig. 4, it illustrates it is provided in an embodiment of the present invention avoid rolling-mill housing from jacking when the installation side that interferes
The preferred structure of method.As shown, this method comprises the following steps:
Vehicle making step S1, the interference position according to interference to hoisting frame determine two of transport to hoisting frame both ends
Difference in height between a transport vehicle, and make two transport vehicles.
Specifically, firstly, confirmation interference especially interferes 21 phase of position to the position at the interference position 21 of hoisting frame 1
For when hoisting frame 1 lift when relative position, i.e., be horizontally set with when hoisting frame 1 in installed position, interference position 21 with
To the relative position between hoisting frame 1；Then, confirmation transport is to the height between two transport vehicles 3 at 1 both ends of hoisting frame
Difference is carried out by left transport vehicle 31 and right transport vehicle 32 respectively to the both ends of hoisting frame 1 (left and right ends as shown in Figure 3)
The tilt angle that support, i.e. confirmation step down to interference position 21 when hoisting frame 1 is located at installation site, and combine wait hang
The length of installation frame 1, calculates in the difference in height and transport vehicle 3 between the i.e. left transport vehicle 31 of two transport vehicles 3 and right transport vehicle 32
Minimum altitude, that is, left transport vehicle 31 height so that the both ends to hoisting frame 1 are individually positioned in left transport vehicle 31 and right fortune
On defeated vehicle 32, to not interfered between hoisting frame 1 and interference position 21, wherein minimum altitude, that is, left fortune in transport vehicle 3
The height of defeated vehicle 31 can be the height of interference part position 21；Finally, being left transport vehicle 31 and right transport vehicle according to two transport vehicles 3
Minimum altitude, that is, left transport vehicle 31 height in difference in height and transport vehicle 3 between 32, makes two transport vehicles 3.Its
In, interference position 21 can on installation frame 2 position or dependency structure, also can treat hoisting machine certainly for other equipment
The interference position of frame 1 or dependency structure.
Rack shift step S2 will be lifted to hoisting frame to two transport vehicles, be hung with being treated by two transport vehicles
The both ends of mounting mechanism are supported, so as to step down to hoisting frame to interference position.
Specifically, firstly, will be hung to hoisting frame 1 on two transport vehicles 3, i.e., to the left and right ends of hoisting frame 1 point
It is not hung on left transport vehicle 31 and right transport vehicle 32, is supported with the both ends for treating hoisting mechanism 1 by two transport vehicles 3.
Since there are differences in height between two transport vehicles 2, therefore it is obliquely installed on two transport vehicles 2 to hoisting frame 1；Further preferably
Ground, to the end (left end as shown in Figure 3) on hoisting frame 1 from separate interference position 21 extremely close to the end at interference position 21
(right end as shown in Figure 3, the i.e. head to hoisting frame 1) is obliquely installed upwards to hoisting mechanism 1, i.e., from left to right wait lift
Rack 1 tilts upwards.
Vehicle trafficking step S3, will be traversing to installation site to hoisting frame by two transport vehicles.
It specifically, is that left transport vehicle 31 and right transport vehicle 32 will be transported to hoisting mechanism 1 to installation by two transport vehicles 3
Position.Due to being tilted upwards to hoisting frame 1 from left to right, that is to say, that the height of left transport vehicle 31 is lower than right transport vehicle 32
Height so that when hoisting frame 1 is located at installation site, the head to hoisting frame 1 is higher than interference position 21, avoids
The interference of the jacking installation of hoisting frame 1 is treated at interference position 21, especially, be can avoid installation frame 2 and is treated installing mechanism 1
Interference, moreover, being higher than interference position 21 also when the head of hoisting frame 1 can avoid waiting hanging when the jacking of the head of hoisting frame 1
Interference between the head and interference position 21 of installation frame 1, to solve, two rolling-mill housing spacing are too short to be led to not install
The case where, the efficient installation of rolling-mill housing under confined condition is realized, jacking number is reduced, shortens the lifting time, it can be into one
Step expands the scope of application of hydraulic jacking device.
Rack jacks step S4, jacks to hoisting frame.
Specifically, the jacking for realization to hoisting frame 1, it is preferable that hoisting frame can be treated by hydraulic jacking device 4
1 carries out jacking installation；Firstly, by revolute hydraulic will be connected to the head of hoisting frame 1 (right part as shown in Figure 3)
It rises on device 4；Then, the head to hoisting frame 1 is jacked by hydraulic jacking device 4, so as to jack to hoisting frame 1 same
When rotated around the link position to hoisting frame 1 and hydraulic jacking device 4 so that waiting for hoisting machine while 1 raising of rolling-mill housing
Frame 1 rotates counterclockwise therewith, until being in upright state to hoisting frame 1, wherein due to the head connection to hoisting frame 1
On hydraulic jacking device 4, and to the close interference position 21 in the head of hoisting frame 1, therefore will be first and by near-end to hoisting frame 1
The transport vehicle 3 of position separates, i.e., can the first fortune with close to interference position 21 to hoisting frame 1 during jacking to hoisting frame 1
Defeated vehicle 3 is that right transport vehicle 32 separates, and the transport vehicle 3 that can first will be close to interference position 21 is withdrawn, i.e., to hoisting frame 1 and right fortune
Defeated vehicle 32 can first withdraw right transport vehicle 32 after separating；Finally, continuing through the jacking of hydraulic jacking device 4 to hoisting frame 1
Head, so that being separated between hydraulic jacking device 4 and left transport vehicle 31.
To sum up, the installation method provided in this embodiment interfered when rolling-mill housing being avoided to jack passes through two height and exists
The transport vehicle 3 of difference in height treats hoisting frame 1 and is supported and transports, so as to be obliquely installed to hoisting frame 1, and then avoids doing
The interference that the jacking installation of hoisting frame 1 is treated at position 21 is related to, especially, installation frame 2 is can avoid and treats the dry of installing mechanism 1
It relates to, to solve two rolling-mill housing spacing too short the case where leading to not installation, realizes rolling-mill housing under confined condition
Efficiently installation reduces jacking number, shortens the lifting time.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
