Description

Technical Field

[0001] This utility model belongs to the field of civil defense engineering technology, and in particular relates to an RFP type filter absorber bracket. Background Technology

[0002] As a key component of the ventilation system for toxic substances in civil defense projects, the RFP series filter absorber can effectively filter out harmful substances such as toxic fumes, toxic fog, bioaerosols, radioactive dust, and persistent toxic agent vapors from contaminated air, providing clean air for personnel inside the project.

[0003] In the application of RFP type filter absorbers, the bracket is usually a fixed structure, which is difficult to adjust according to the actual installation space, the number of filter absorbers and their layout. It cannot adapt to different installation conditions. The fixed structure of the bracket may not be able to meet the installation requirements of multiple filter absorbers. Moreover, the installation of filter absorbers often requires the cooperation of many people, with the help of complex hoisting equipment and tools. The operation process is complicated and consumes a lot of manpower and time. Therefore, there is a need to provide an RFP type filter absorber bracket that can increase the installation height and position according to the actual working conditions. At the same time, it adopts an integrated hanger design to hoist the filter absorber at a specified height. Utility Model Content

[0013] In the following description, embodiments of the RFP type filter absorber support of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates an embodiment of an RFP-type filter absorber bracket, comprising a support base 1; an expansion bracket 2 is mounted on the top of the support base 1, and a top bracket 3 is mounted on the top of the expansion bracket 2; gas pipes 8 are mounted on both sides of the support base 1, and the gas pipes 8 are connected to the inlet and outlet ends of the filter absorber 4 via flexible compensation pipes; insertion posts 9 are welded to the four corners of the bottom of the expansion bracket 2 and the top bracket 3; and rectangular slots 10 adapted to the insertion posts 9 are provided at the four corners of the top of the support base 1, the expansion bracket 2, and the top bracket 3. The insert 9 is inserted into the inner cavity of the rectangular slot 10. A bolt 11 is provided through one side of the insert 9. The insert 9 is fixedly installed in the inner cavity of the rectangular slot 10 by the bolt 11. With the cooperation of the insert 9, the rectangular slot 10 and the bolt 11, the number of support positions can be increased according to the actual installation requirements, so as to adapt to different installation conditions. The top of the support base 1 and the expansion bracket 2 are both equipped with filter absorbers 4. The top of the support base 1, the expansion bracket 2 and the top frame 3 are all equipped with positioning components 5. The support frame 5 includes two slidable support beams 51. The right side of the inner cavity of the support base 1, the auxiliary frame 2, and the top frame 3 are all rotatably connected to a double-threaded screw 52 via bearings. A threaded sleeve 53 is fixedly connected to the bottom of the support beam 51, and the threaded sleeve 53 is threaded onto the surface of the double-threaded screw 52. A rocker plate 54 is fixedly connected to the left end of the double-threaded screw 52. Guide rails 55 are fixedly connected to the front and rear sides of the top of the support base 1, the auxiliary frame 2, and the top frame 3. Slide seats 5 are fixedly connected to the front and rear ends of the support beam 51. 6. The slide block 56 is slidably connected to the surface of the guide rail 55. Through the cooperation of the guide rail 55 and the slide block 56, the support beam 51 is limited and guided, which improves the stability of the support beam 51 during the sliding process. At the same time, the synchronously sliding support beam 51 enables the filter absorber 4 to be centrally installed. The rear side of the top of the top frame 3 is fixedly connected to the hoisting frame 6. The top of the inner cavity of the hoisting frame 6 is fixedly installed with a hand chain hoist 7. The lifting end of the hand chain hoist 7 is fixedly connected to the filter absorber 4 located above through the sling.

[0015] Working Principle: In use, the user moves the filter absorber 4 to the lower part of the inner cavity of the hoisting frame 6, then releases the lifting end of the hand chain hoist 7 and secures the filter absorber 4 to the lifting end using slings. The user then operates the chain of the hand chain hoist 7, causing it to lift the filter absorber 4. Once the filter absorber 4 reaches the designated installation height, the user pushes it backward and releases the chain of the hand chain hoist 7 a certain length, allowing the filter absorber 4 to reach the top of the top frame 3, the auxiliary frame 2, or the support base frame 1, placing it on top of two adjacent support beams 51. The user then rotates the rocker disc 54, which in turn rotates the bidirectional threaded screw 52. The interaction between the threads on the surface of the bidirectional threaded screw 52 and the threads on the inner wall of the threaded sleeve 53 further facilitates the operation of the filter absorber. This causes the two supporting beams 51 to move in opposite directions, while the slide block 56 slides on the surface of the guide rail 55. This causes the supporting beams 51 to press against the bottom edge of the filter absorber 4 (the filter absorber 4 shell is composed of a square center and two bucket-shaped sides, with a certain height difference between the center and the sides). This fixes the filter absorber 4 in place. Then, the slings and the lifting end of the hand chain hoist 7 are untied, and the next filter absorber 4 can be hoisted and installed. After all the filter absorbers 4 are installed, the inlet and outlet ends of the filter absorbers 4 are connected to the gas pipeline 8 through the flexible compensation pipe. The number of installations using the additional bracket 2 can be increased or decreased according to actual usage needs (the length of the hoisting bracket 6 is set according to actual support needs), thereby meeting the installation needs of different numbers of filter absorbers 4.

[0016] In summary, the RFP-type filter absorber bracket supports the filter absorber 4 through the combined use of the base frame 1, the auxiliary frame 2, and the top frame 3. The filter absorber 4 is then hoisted using the hoisting frame 6 and the hand-operated hoist 7. Finally, with the assistance of the positioning component 5, the filter absorber 4 is stably installed, thus achieving the goals of labor-saving and convenient installation and easy adjustment of installation specifications.
