[0034] The application will be further described below in conjunction with embodiments, and the purpose is only to better understand the content of the application, and thus the examples do not limit the protection scope of the application.

[0035] Referring to Figures 1 to 7 , the application provides a device installation correction construction method, and the construction process is as follows:

[0036] Firstly, after the device foundation 1 is constructed, the surface of the device foundation 1 is pre-marked, the spacer groups are set according to the marking, the elevation of the top plane of the spacer groups is detected by using a levelness detection device, the height of each spacer in the spacer groups is adjusted by using the first inclined spacer 3, all the top planes of the spacers in the spacer groups are on the same horizontal plane, so as to ensure the installation elevation of the device 5;

[0037] Secondly, the device 5 is hoisted to the spacer groups, and the device base plate 4 falls on the top surface of the spacer groups;

[0038] Third step, install the correction device at the appropriate position in each direction of the device 5:

[0039] S31, make the pull rod 6, the front end of which is provided with a hook head 7, and the rear end of which is provided with a vertical bolt hole plate 8; extend the front end of the pull rod 6 into the gap between the device base plate 4 and the device foundation 1, and hook the hook head 7 of the pull rod 6 on the fixed structure to limit the outward displacement of the pull rod 6;

[0040] S32, set the second inclined spacer 12 at the lower side of the rear end of the pull rod 6 to keep the pull rod 6 horizontal;

[0041] S33, make the top rod 9 of a certain length, and set a through threaded hole at the rear end of the top rod 9, and install the hand lever 10 through threaded connection in the through threaded hole;

[0042] S34, install the front end of the top rod 9 into the bolt hole plate 8, and rotate the hand lever 10 to make the top rod 9 pass through the bolt hole plate 8 and the front end contact the side wall of the device base plate 4;

[0043] Fourth step, continue to rotate the hand lever 10, and make the front end of the top rod 9 further move forward with the fixed structure at the front end of the pull rod 6 as the fulcrum, so as to push the device base plate 4 to move slowly, thereby finely adjusting the position and direction of the device 5 on the device foundation 1.

[0044] Determine the elevation of the device 5 by using the conventional spacer positioning method, and this construction method solves the problem of inaccurate position of the device 5 on the plane of the device foundation 1 when hoisting and placing, and the inaccurate position includes the overall offset error of the device 5, the skew of the device 5 (the offset of some points), etc. Since the shapes of the devices 5 are various and the offset errors are different, the point positions and the number of correction devices are not limited in this scheme. Assuming that it is a rectangular device base plate 4, one correction device can be installed on the short side and two correction devices can be installed on the long side, and the specific number is determined according to the offset of the device 5 after re-measurement. This method installs the correction device after the device 5 is hoisted onto the device foundation 1, and the correction device uses the fixed structure on the adjacent device foundation 1 as the fulcrum, and pushes the device base plate 4 through the top rod 9, thereby affecting the position of the device 5 in the plane. Compared with the chain block mechanism, the correction device provided in this scheme has small size and does not need to reserve space for installation and operation. This method can simultaneously adjust the position of the device 5 at multiple points, can translate the device 5 as a whole, can realize single-point movement of the device, has high speed and high precision.

[0045] Specifically, if the device foundation 1 adopts a straight-buried bolt 2 foundation, the fixing structure is a straight-buried bolt 2 rod pre-buried on the device foundation 1, the pull rod 6 adopts a hook head 7 with a question mark shape at the front end, and the front end is hooked on the straight-buried bolt 2. If the device foundation 1 adopts a reserved bolt hole 11 foundation, the fixing structure is a reserved bolt hole 11 on the device foundation 1, and the pull rod 6 adopts a hook head 7 with an L shape at the front end, and the front end is hooked on the reserved bolt hole 11.

[0046] The correction device provided by the application comprises:

[0047] The pull rod 6 is horizontally arranged, one end of the pull rod 6 is provided with a hook head 7, and the other end is vertically fixed with a bolt hole plate 8 provided with a bolt hole;

[0049] The hand rod 10 is provided with a threaded head at the lower end, and the threaded head is threadedly fixed with the through threaded hole.

[0050] In the scheme, the pull rod 6 is made of round steel or small square steel.

[0051] If the device foundation 1 adopts a straight-buried bolt 2 foundation, the pull rod 6 takes a round steel bar as the main structure, the front end of the round steel bar is bent to form a hook head 7 with a question mark shape, the rear end of the round steel bar is vertically welded with a bolt hole plate 8, and a bolt hole is arranged above the welding point between the round steel bar and the bolt hole plate 8. The hook head 7 with a question mark shape is hooked on the straight-buried bolt 2, and when the hand rod 10 is rotated to make the top rod 9 further extend to the direction of the base plate 4, the top rod 9 pushes the base plate 4 outward with the straight-buried bolt 2 as the base point.

[0052] If the device foundation 1 adopts a reserved bolt hole 11 foundation, the pull rod 6 takes a small square steel as the main structure, the front end of the small square steel is downwardly bent by 90 degrees to form an L-shaped hook head 7, or a vertical section is welded to form an L-shaped hook head 7; the rear end of the small square steel is upwardly bent by 90 degrees to form a bolt hole plate 8, or a plate block is welded to form a bolt hole plate 8. The vertical part of the L-shaped hook head 7 is hooked on the reserved bolt hole 11 of the device foundation 1, and the top rod 9 pushes the base plate 4 outward with the bolt hole wall as the base point.

[0053] The application has the following beneficial effects compared with the prior art:
