Description

Technical Field

[0001] The utility model belongs to the field of auxiliary equipment for mechanical equipment installation, and particularly relates to a universal rack for equipment installation in a chemical plant. Background Art

[0002] All kinds of pump bodies and motors or pump bodies and supporting motors are important production equipment in chemical plants. These equipment have the operating characteristics of long continuous operation time and large vibration, so they need to be frequently overhauled and repaired. However, at present, almost all the steel structure racks of fixed pump bodies and motors or pump bodies and supporting motors are directly fixed on special cement bases and cannot be moved. During the maintenance process, if the equipment is modified or transformed, the original rack will not be able to cooperate with the installation of the new equipment. Therefore, only pumps or motors of the same or the same type and size used in the preliminary design during the first installation can be replaced. In the case of equipment transformation or rack damage, the maintenance process requires drilling holes on the original rack or temporarily welding steel plates and then drilling holes again to solve the problem. However, processes such as drilling and welding will affect the strength of the original rack to varying degrees, and the repaired rack is likely to be damaged again in a short time, which may also leave certain potential safety hazards for the later operation of the pump body and motor equipment. Summary of the Invention

[0003] The purpose of the present utility model is to solve the technical problems in the prior art that the steel structure racks of pump bodies and motors or pump bodies and supporting motors in chemical plants are directly fixed on special cement bases and cannot be moved, resulting in inconvenient maintenance, and processes such as drilling holes on the original rack or temporarily welding steel plates and then drilling holes again will affect the strength of the rack to varying degrees, and the repaired rack is prone to be damaged again, thus leaving potential safety hazards for the later operation of the pump body and motor equipment.

The width of the moving slideway is slightly larger than the diameter of the bolt in the bolt assembly, so that the steel structure member can move back and forth in the moving slideway when the bolt assembly is loosened.

[0006] Preferably, in the universal rack of the utility model, the number M of the steel structure components is 4, the number N of the bolt assemblies is 4 groups, wherein 2 steel structure components are fixed in parallel on the surface of the cement base, and the other 2 steel structure components are installed in parallel on the horizontal plane formed by the 2 steel structure components fixed on the surface of the cement base through the bolt assemblies, and the steel structure components on the upper and lower surfaces form a "well"-shaped structure as a whole; and the 2 steel structure components on the upper surface can move relative to the 2 steel structure components on the lower surface in the moving slideway in the middle part of the 2 steel structure components on the lower surface when the bolts of the bolt assemblies are loosened.

[0007] Preferably, in the universal rack of the utility model, the number of the steel structure components is 3, the number of the bolt assemblies N is 2 groups, wherein the first steel structure component is fixed on the surface of the cement base, and the remaining two steel structure components are installed in parallel on the surface of the first steel structure component through the bolt assembly, forming a "艹"-shaped structure; and the two steel structure components on the upper surface can move in the moving slideway in the middle part of the first steel structure component on the lower surface or rotate relative to the bolts of the bolt assembly when the bolts of the bolt assembly are loosened.

[0008] Preferably, in the universal rack of the utility model, the number of the steel structure components is 3, the number of the bolt assemblies N is 1 group, wherein the first steel structure component is fixed on the surface of the cement base, and the remaining two steel structure components are fixed on the surface of the first steel structure component through the bolt assembly to form a "M"-shaped structure; and when the bolts of the bolt assembly are loosened, the remaining two steel structure components can move relative to the first steel structure component in the moving slideway in the middle part of the first steel structure component on the lower surface or rotate relative to the bolts of the bolt assembly.

[0009] The utility model is suitable for a universal rack for installing chemical plant equipment, and a movable slide and a track platform are provided in each steel structure component, wherein the slide ensures that the different positions of other steel structure components and motor foundation bolts can be relatively moved, and the setting of the track platform ensures the connection stability between the steel structure components, and at the same time, the bolts can be hidden to avoid interfering with the mobility of the rack. It can be seen that since the different steel structure components of the universal rack of the utility model can be relatively moved, the needs of equipment installation, adjustment, maintenance and replacement at different installation positions are met, so that in the production process, the running equipment can be repaired or replaced in time according to actual needs, which improves the efficiency of equipment inspection and maintenance and reduces the damage to the supporting infrastructure caused by the updated equipment.
