Description

Technical Field

[0001] This utility model relates to the field of combined platform support and alignment technology, and more specifically, to a bottom alignment structure for a large equipment combined platform. Background Technology

[0002] Currently, the levelness requirements for the combined platforms of various large equipment are high. Levelness is used to ensure the accuracy of the equipment combination on the platform. Previously, the bottom of the combined platform of this type of large equipment was aligned by pre-embedded base plate and the addition of shims. However, this process requires repeated measurement, addition and adjustment of shims. The number of shims is large, and grouting of the shims is required after installation. The installation accuracy of the combined platform is poor. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a bottom alignment structure for a large equipment combination platform.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A bottom alignment structure for a large equipment assembly platform includes several channel steels installed at the bottom of the large equipment assembly platform, as well as a mounting frame, a base plate, side plates, fasteners, screws, nuts, a mounting plate, connecting rollers, a limit plate, and scale lines.

[0006] The mounting frame includes a base plate and side plates that are symmetrically distributed about the base plate and welded perpendicularly to the base plate. The inner side of the side plates is tightly fitted to the side wall of the channel steel, and several fasteners are welded to the bottom of the base plate.

[0007] One end of the screw is rotatably connected to the center of the base plate, and a nut is threaded onto the screw.

[0008] The main body is a rectangular mounting plate welded to the nut, and the mounting plate has a through hole in the center that allows the screw to pass through;

[0009] The two ends of the connecting roller are welded to the outer side of the side plate and the U-shaped limiting plate of the main body, respectively. The limiting plate is closely attached to the front and rear sides of the channel steel and is spaced apart from the mounting plate.

[0010] The scale lines are marked on the front side of one of the side panels.

[0011] Furthermore, a rotating component for easy operation is welded to the other end of the screw.

[0012] Furthermore, the fastener is an anchor bolt.

[0013] Furthermore, the mounting plate is covered with a transparent protective shell located on the outside of the rotating component.

[0014] Furthermore, the mounting plate is provided with fillet welds.

[0015] Furthermore, the screw is made of alloy steel.

[0016] Furthermore, both the base plate and the side plates are made of Q420B steel.

[0017] Furthermore, the side plate is provided with several reinforcing ribs.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Compared with existing technologies, this application adopts a finely adjustable lifting bottom alignment structure. The bottom of the combined platform support channel steel is equipped with an adjustable mounting plate, and the center of the mounting plate is equipped with a bolt adjustment structure. The bottom adopts a U-shaped mounting frame structure for installation, so the channel steel can be freely adjusted up and down inside the mounting frame. When the upper ends of several channel steels are adjusted to the same height, welding can be carried out between the contact surfaces of the channel steel and the side plate. This technical solution ensures the installation quality of the bottom alignment structure of the large equipment combined platform and has the technical characteristics of feasibility, safety and stability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0026] like Figure 1 and Figure 2As shown, a bottom alignment structure for a large equipment assembly platform includes several channel steels 1 installed at the bottom of the large equipment assembly platform, as well as a mounting frame 2, a base plate 21 (made of Q420B steel), side plates 22 (made of Q420B steel), fasteners, screws 3 (made of alloy steel), nuts 4, mounting plates 5, connecting rollers 6, limiting plates 7, and scale lines 8.

[0027] Mounting bracket 2 includes a base plate 21 and side plates 22 that are symmetrically distributed about the base plate 21 and welded perpendicularly to the base plate 21. The inner side of the side plate 22 is tightly fitted to the side wall of the channel steel 1. Several fasteners are welded to the bottom of the base plate 21 (specifically, the fasteners are anchor bolts, which are not shown in the figure).

[0028] One end of the screw 3 is rotatably connected to the center of the base plate 21, and a nut 4 is threaded onto the screw 3;

[0029] The mounting plate 5, which is rectangular in shape, is welded to the nut 4, and the mounting plate 5 has a through hole in the center that allows the screw 3 to pass through;

[0030] The two ends of the connecting roller 6 are welded to the outer side of the side plate 22 and the U-shaped limiting plate 7 respectively. The limiting plate 7 is closely attached to the front and rear sides of the channel steel 1 and is distributed at intervals with the mounting plate 5.

[0031] The scale line 8 is marked on the front side of one of the side plates 22.

[0032] To ensure that the side plate 22 is always in close contact with the channel steel 1, the above embodiment is further optimized by providing several reinforcing ribs on the side plate 22 to further improve its bending resistance. The reinforcing ribs are not shown in the figure.

[0033] To facilitate the rotation of the drive screw 3 and thus adjust the height of the channel steel 1, further optimizations to the above embodiment are made, such as... Figure 1 As shown, the other end of the screw 3 is welded with a convenient rotating part 9, which can be a knob or nut 4.

[0034] The working process of this utility model is as follows:

[0035] First, complete the full welding of the base plate 21 and the side plate 22. Then, weld several anchor bolts from the bottom of the base plate 21. Then, the mounting frame 2 can be firmly anchored on a flat ground. During installation, ensure that the verticality and horizontality of the mounting frame 2 meet the standards.

[0036] Then, the channel steel 1 is placed from top to bottom. At this time, the front and back sides of the channel steel 1 are tightly fitted with the inner walls of the two sides of the limiting plate 7, and the side walls of the channel steel 1 are tightly fitted with the two side plates 22. When the bottom surface of the channel steel 1 reaches the area where the lowest point of the scale line 8 is located, it stops moving downward. The purpose of setting the scale line 8 is to ensure that the bottom position of several channel steels 1 is basically the same when they are placed into different mounting brackets 2, so that no large-scale adjustment is needed later.

[0037] After the channel steel 1 is limited by the limiting plate 7 and the scale line 8 and is tightly attached to the side plate 22, the mounting plate 5 is then welded to the inner wall of the channel steel 1 (before welding, a level is used to ensure that the surface of the mounting plate 5 is flush). After the welding is completed, the rotating part 9 is rotated so that the mounting plate 5 can be adjusted and raised synchronously with the channel steel 1. When the tops of several channel steels 1 are all at the same height, the full welding between the channel steel 1 and the side plate 22 can be completed one after another. At this time, the alignment process is completed to overcome the errors in the production and preparation process of the mounting frame 2 and the channel steel 1. Finally, the large equipment combination platform is installed with the channel steel 1, so that the level of the large equipment combination platform is qualified. This solution does not require the addition of multiple shims to achieve alignment, and the alignment accuracy is significantly improved. The operation process is convenient.

[0038] To provide a stable base for subsequent welding and reduce assembly difficulty, the above-described embodiment is further optimized by providing a fillet weld on the mounting plate 5. The fillet weld allows the mounting plate 5 to be welded to the channel steel 1 with a certain error angle, without the need for precise alignment.

[0039] To prevent the rotating component 9 from being accidentally rotated after the height of the channel steel 1 has been adjusted but before the welding of the channel steel 1 to the side plate 22 is completed, in some embodiments, such as Figure 3 As shown, the mounting plate 5 is covered with a transparent protective shell located outside the rotating part 9.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
