Technical Field

[0001] The invention belongs to the technical field of equipment installation construction, and in particular relates to an equipment installation correction construction method. Background Art

[0002] With the development of electrical and automation technology, the accuracy of equipment installation has become increasingly important, playing an important role in ensuring equipment operation, increasing equipment service life, ensuring safe production, and improving production efficiency.

[0003] The installation and construction of the equipment includes two aspects of precision calibration. One is whether the bottom surface of the equipment on the vertical plane is on the same level. The other is that the position of the equipment on the horizontal plane needs to be finely adjusted.

[0004] In traditional equipment installation and correction construction, the layout must be done in advance first; then the elevation is set, and the horizontal position is fine-tuned by positioning and adjusting the pads. Specifically, the position and height of each pad in the composite pad group are measured using a level and other measuring equipment. The construction accuracy of each pad ensures the equipment installation elevation; In order to ensure the position accuracy of the equipment on the basic plane, fall chains are usually set in the four directions of the equipment. The fall chains are pulled and acted on the equipment to adjust the installation accuracy of the equipment on the plane.

[0005] The existing fall chain adjustment method is cumbersome to operate, and requires an assumed fall chain connection point, requiring sufficient space around the equipment to install the fall chain mechanism. Under some special conditions, the fall chain cannot be pulled and installed due to environmental limitations. The adjustment operation is inconvenient and the accuracy is not easy to control. Equipment calibration takes a long time. Summary of the invention

[0015] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0016] See also Figures 1 to 7 The present invention provides an equipment installation and correction construction method, and the construction process is as follows: In the first step, after the construction of the equipment foundation 1 is completed, the surface of the equipment foundation 1 is pre-laid out, and the shim group is set according to the laid-out. The elevation of the top plane of the shim group is detected by using the level detection equipment, and the height of each shim in the shim group is adjusted by using the first inclined shim 3, so that the tops of all shims in the shim group are on the same horizontal plane, thereby ensuring the installation elevation of the equipment 5; The second step is to hoist the equipment 5 onto the pad iron group so that the equipment base plate 4 falls on the top surface of the pad iron group; The third step is to select a suitable position in each direction of the device 5 to install the correction device: S31, a pull rod 6 is made, the front end of the pull rod 6 is provided with a hook head 7, and the rear end is provided with a vertical bolt hole plate 8; the front end of the pull rod 6 is extended into the gap between the equipment base plate 4 and the equipment foundation 1, and the hook head 7 of the pull rod 6 is hooked on the fixed structure to limit the outward displacement of the pull rod 6; S32, a second inclined washer 12 is provided at the lower side of the rear end of the pull rod 6 to keep the pull rod 6 horizontal; S33, taking a threaded rod of a certain length to make a push rod 9, a through threaded hole is set at the rear end of the push rod 9, and a hand rod 10 is installed in the through threaded hole through a threaded connection; S34, insert the front end of the push rod 9 into the bolt hole plate 8, and rotate the hand lever 10 so that the push rod 9 passes through the bolt hole plate 8 and the front end contacts the side wall of the equipment base plate 4; The fourth step is to continue rotating the hand lever 10 so that the front end of the top screw moves further forward with the front end fixed structure of the pull rod 6 as a lever point, thereby pushing the equipment base plate 4 to move slowly, thereby finely adjusting the position and direction of the equipment 5 on the equipment foundation 1.

[0017] The elevation of the equipment 5 is determined by the conventional shim positioning method. This construction method specifically solves the problem of inaccurate position of the equipment 5 when it is hoisted and placed on the plane of the equipment foundation 1. The inaccurate position includes the overall deviation of the equipment 5 to the left, the deviation of the equipment 5 (some point deviation), etc. Since the equipment 5 has various shapes and different deviation errors, this scheme does not limit the points and number of corrections. Assuming that it is a rectangular equipment base plate 4, one correction device can be installed on the short side and two correction devices can be installed on the long side. The specific situation depends on the deviation of the equipment 5 obtained after re-measurement. This method installs the correction device after the equipment 5 is hoisted to the equipment foundation 1. The correction device uses the fixed structure on the adjacent equipment foundation 1 as a leverage point, and pushes the equipment base plate 4 through the push rod 9, thereby affecting the position of the equipment 5 in the plane. Compared with the chain-falling mechanism, the correction device provided by this scheme is small in size and does not need to reserve space for its installation and operation. This method can adjust the position of the equipment 5 at multiple points at the same time, and can translate the equipment 5 as a whole, or realize the single-point movement of the equipment, with fast adjustment speed and high precision.

[0018] Specifically, if the equipment foundation 1 adopts a direct-buried bolt 2 foundation, the fixing structure is a direct-buried bolt 2 rod pre-buried on the equipment foundation 1, and 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 direct-buried bolt 2. If the equipment foundation 1 adopts a reserved bolt hole 11 foundation, the fixing structure is a reserved bolt hole 11 on the equipment foundation 1, and the pull rod 6 adopts a hook head 7 with an L-shaped front end, and the front end is hooked on the reserved bolt hole 11.

[0019] The correction device of the present invention comprises: The pull rod 6 is arranged horizontally, a hook head 7 is arranged at one end of the pull rod 6, and a bolt hole plate 8 is vertically fixedly connected to the other end, and the bolt hole plate 8 is provided with bolt holes; A push rod 9 is provided with an external thread on its surface and is installed in the bolt hole plate 8. The push rod 9 is parallel to the pull rod 6, and a through threaded hole is provided at one end of the push rod 9 away from the hook head 7; The hand lever 10 has a threaded head at its lower end, which is threadedly fixed to the through threaded hole.

[0020] In this solution, the pull rod 6 is made of round steel or small square steel.

[0021] If the equipment foundation 1 adopts the direct-buried bolt 2 foundation, the pull rod 6 is made of round steel bars as the main structure, the front end of the round steel bars is bent to form a question mark-shaped hook head 7, the rear end of the round steel bars is vertically welded to the bolt hole plate 8, and a bolt hole is set above the welding point between the round steel bars and the bolt hole plate 8. The question mark-shaped hook head 7 is hooked on the direct-buried bolt 2, and when the hand lever 10 is rotated to make the push rod 9 further extend toward the base plate 4, the push rod 9 pushes the base plate 4 outward with the direct-buried bolt 2 as the base point for leverage.

[0022] If the equipment foundation 1 adopts the foundation with reserved bolt holes 11, the pull rod 6 is made of small square steel as the main structure, the front end of the small square steel is bent downward 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 bent upward by 90 degrees to form a bolt hole plate 8, or a plate 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 equipment foundation 1, and the bolt hole wall is used as the base point for leverage, and the top rod 9 pushes the base plate 4 outward.

[0023] The beneficial effects of the present invention compared with the prior art are as follows: The correction device provided by the present invention is small in size and has no requirements on the size of the equipment space. The method solves the problem of being restricted by installation conditions and does not require any additional hanging points. The operation is simple, convenient and flexible, and the construction efficiency is significantly improved. The method has a wide range of uses and can be used in various equipment installation and correction scenarios. It can effectively improve installation accuracy, shorten the correction cycle, and create conditions for project performance.

All equivalent changes made using the contents of the present specification and its drawings are included in the scope of rights of the present invention.
