Description

Technical Field

[0001] This utility model belongs to the technical field of rotary air preheater testing equipment, specifically relating to a preheater test hanging fixture. Background Technology

[0002] The preheater is mainly assembled from a central cylinder and multiple modular compartments. Each modular compartment has an upper and lower mounting plate fixed to its corresponding upper and lower ends on the central cylinder side. The upper mounting plate has fixing holes, and the lower mounting plate has U-shaped positioning grooves. The modular compartments are connected to the central cylinder through these mounting plates. Because the connection between the modular compartments and the central cylinder has a certain curvature requirement, if there are errors in the manufactured modular compartments during on-site installation, it will affect the installation of the preheater, requiring rework and causing significant economic losses. Therefore, a preheater trial-installation fixture is needed to solve the above technical problems. Utility Model Content

The multiple support tubes are evenly distributed along the circumference of the top plate. Multiple upper mounting holes are evenly distributed along the circumference of the edge of the top plate, and fixing pins are fitted into the upper mounting holes. An upper support ring is fixed to the upper surface of the bottom plate, and multiple lower mounting holes are evenly distributed along the circumference of the bottom plate corresponding to the outer ring surface of the upper support ring, and positioning pins are fitted into the lower mounting holes.

[0004] Preferably, a lower support ring is fixed to the lower surface of the base plate.

In addition, devices or components not limited in this utility model, such as modular compartments, upper hanging plates, lower hanging plates, upper support rings, and lower support rings, all adopt conventional technical means and conventional equipment in the field.

[0010] Working principle: A simple mounting frame is made to simulate the center cylinder. The pre-produced modular compartments are installed one by one on the mounting frame. The installation process is simple and efficient. It can confirm whether multiple modular compartments can be effectively spliced ​​together and whether their error is within the allowable range. Defective modular compartments can be repaired in time until they are qualified. This can avoid the situation of unqualified modular compartments during on-site installation, reduce costs and improve product quality.

[0011] The beneficial effects of this utility model are: simple structure, easy to use, can effectively pre-install the produced modular storage compartments, test whether the modular storage compartments are qualified, avoid the occurrence of unqualified modular storage compartments during on-site installation, reduce the cost of rework, and improve the factory quality of modular storage compartments.

[0022] Example

[0023] like Figure 1-7 As shown, this utility model provides a preheater trial mounting fixture, including a mounting frame that mates with the modular compartment 9 of the preheater; the mounting frame includes a circular top plate 1 and a circular bottom plate 5, the top plate 1 and the bottom plate 5 are fixedly connected by a plurality of vertical support pipes 3, the plurality of support pipes 3 are evenly distributed along the circumference of the top plate 1, the edge of the top plate 1 has a plurality of upper mounting holes 8 evenly distributed along the circumference, the upper mounting holes 8 are fitted with fixing pins 2, the upper surface of the bottom plate 5 is fixed with an upper support ring 7, the outer ring surface of the upper support ring 7 is corresponding to a plurality of lower mounting holes 6 evenly distributed along the circumference of the bottom plate 5, the lower mounting holes 6 are fitted with positioning pins 10.

[0024] A lower support ring 4 is fixed to the lower surface of the base plate 5.

[0025] The connection between the lower support ring 4 and the base plate 5 is an arc surface, and the base plate and the support ring are machined with double-sided bevels of 35°.

[0026] The number of upper mounting holes 8 and lower mounting holes 6 is the same, both being 24, and they correspond one-to-one.

[0027] The number of upper mounting holes 8 and lower mounting holes 6 is the same as the number of modular compartments 9 of the preheater.

[0028] The upper ends of the multiple support tubes are respectively located on the same diameter of the top plate and the corresponding upper mounting holes, while the lower ends of the multiple support tubes are respectively located on the same diameter of the bottom plate and the corresponding lower mounting holes. This ensures that the corresponding modular compartments can be supported, increasing the overall load-bearing capacity of the mounting frame.

[0029] Working Principle: A simple mounting frame is constructed to simulate the center cylinder. The pre-produced modular compartments (9) are installed one by one onto the mounting frame. Specifically, the modular compartments are placed in their corresponding positions on the base plate. At this point, the lower mounting plate is on the base plate, with the opening of the U-shaped positioning groove of the lower mounting plate facing the upper support ring. One end of the lower mounting plate is an arc surface that matches the outer ring surface of the upper support ring. The lower mounting plate and the outer ring surface of the upper support ring fit closely together. The positioning pin in one of the lower mounting holes on the base plate is precisely engaged in the positioning groove. The upper mounting plate is on the top plate, and a fixing pin passes through the fixing hole of the upper mounting plate and... The corresponding mounting holes allow the upper mounting plate to be fixed to the top plate, thus installing one modular compartment on the mounting frame. Installing all 24 modular compartments on the mounting frame effectively verifies the quality and conformity of the modular compartments. The entire process is simple and efficient, confirming whether multiple modular compartments 9 can be effectively spliced ​​together and whether their errors are within the allowable range. Defective modular compartments 9 can be promptly reworked until they are acceptable, thus avoiding the occurrence of defective modular compartments 9 during on-site installation, reducing costs, and improving product quality.
