An adjustable counterforce support for a device resistance testing system

Abstract

This invention proposes an adjustable reaction support for an equipment resistance testing system, comprising: a fixed support frame, a support, vertical beams, and horizontal beams. The fixed support frame is installed on the ground, and its upper surface is flat. A base plate is fixedly connected to one side of the upper part of the flat surface. Side plates are fixedly connected to the opposite sides of the two vertical beams. A flat plate is fixedly connected to the lower end face of the horizontal beam. The side plates, flat plate, base plate, and panel form a closed cavity with an opening only on the right side. The adjustable reaction support proposed in this invention allows adjustment of the positions of the horizontal and vertical beams according to the size of the equipment being tested, thereby changing the structural strength of the support and avoiding insufficient reaction support strength in equipment resistance testing. Furthermore, the horizontal and vertical beams form a relatively closed testing area, which can eliminate the influence of reflected waves from the surrounding walls and improve the accuracy of equipment testing.

Description

Technical Field

[0001] This invention relates to explosion shock wave testing technology, and more particularly to testing technology for the explosion resistance performance of equipment, specifically an adjustable reaction support for an equipment resistance testing system. Background Technology

[0002] The equipment resistance testing system includes an explosion wave simulation device and a test section. The explosion wave simulation device uses chemical explosion to generate simulated explosion shock waves. The equipment under test is installed in the test section, and the explosion resistance performance of the equipment under test in the ground or underground engineering structure under specific explosion loads is obtained through testing.

[0003] In existing stress testing systems, to ensure sufficient structural strength during testing, the test sections are fixed once connected. The equipment under test (mainly protective doors and windows) is directly fixed to the shock wave channel of the test section via a closed frame, with the frame providing support and reaction force. However, in actual testing, because the measuring points are fixed, the cross-sectional area of ​​the shock wave channel is also fixed. Since doors and windows vary in size and blast resistance, the simulated explosion shock waves in the drive section also vary in size. Consequently, the impact on the closed frame also varies. The portion of the frame supporting the equipment under test is prone to strain due to excessive load, and in some cases, the frame support may deform even without damage to the equipment under test, thus affecting the final test results. Summary of the Invention

[0004] In response to the problems mentioned in the background, the purpose of this invention is to provide an adjustable reaction support for an equipment resistance testing system, so as to solve the problem that the strength of the reaction support is often insufficient in equipment resistance testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable reaction support for an equipment resistance testing system includes: a fixed support frame, a support, a vertical beam and a horizontal beam. The fixed support frame is installed on the ground, and the upper surface of the fixed support frame is a plane. A base plate is fixedly connected to one side of the upper part of the plane, and multiple mounting holes are evenly distributed on the base plate.

[0007] The bracket is a vertical plate frame structure. Its lower end is fixedly connected to the upper surface of the fixed support frame and is located on the right side of the base plate. The left side of the bracket is covered with a panel. A set of connection holes is provided on both sides of the upper part of the panel. Each set of connection holes has multiple holes.

[0008] The panel has a doorway for installing testing equipment at the bottom center.

[0009] Vertical beams are provided on both sides of the doorway. The lower end of each vertical beam is connected to the mounting holes on the base plate by bolts, and the upper end of each vertical beam is provided with a positioning slot.

[0010] A horizontal beam is provided above the doorway. The two ends of the horizontal beam are respectively connected to the connecting holes on both sides of the upper part of the panel by bolts, and the two ends of the horizontal beam are respectively positioned in the positioning slots of the two vertical beams.

[0011] The two vertical beams are each fixedly connected to a side plate on their opposite sides, and the horizontal beam is fixedly connected to a flat plate on its lower end face. The side plates, flat plates, bottom plates, and panel form a closed cavity with an opening only on the left side.

[0012] The vertical beam is composed of a vertical rectangular frame and a positioning rod. The rectangular frame is vertically installed on the left side of the panel, and the lower end of the rectangular frame is connected to the upper surface of the base plate. The positioning rod is fixedly connected to the left side of the rectangular frame, and the lower end of the positioning rod is connected to the left end face of the base plate. The upper end of the positioning rod extends to the top of the rectangular frame, forming the positioning slot with the top of the rectangular frame.

[0013] The beam is a horizontal rectangular frame structure, with its right side frame connected to the connecting holes on the panel and its left side frame connected to the positioning rod by bolts.

[0014] The vertical beam also has a positioning support component installed in its positioning slot, which is used to adjust the positioning height of the horizontal beam.

[0015] The positioning support assembly includes multiple U-shaped plates connected in parallel. The right end of each U-shaped plate abuts against the panel, and the left end is connected to the positioning rod by bolts.

[0016] A first mating beam connects the upper left ends of the two vertical beams, and a second mating beam connects the lower left ends of the two vertical beams. Both the first and second mating beams are parallel to the horizontal beam. The left end face of the horizontal beam is connected to the first mating beam, and the left end face of the base plate is connected to the second mating beam.

[0017] The beneficial effects of the present invention are as follows: The adjustable reaction support for equipment resistance testing system proposed in this invention can adjust the position of the horizontal and vertical beams according to the size of the testing equipment, thereby changing the structural strength of the adjustable reaction force, avoiding the problem of insufficient reaction support strength in equipment resistance testing, and the horizontal and vertical beams form a relatively closed testing area, which can eliminate the influence of reflected waves from the surrounding walls and improve the testing accuracy of the equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-4 As shown, an adjustable reaction support for an equipment resistance testing system includes: a fixed support frame 101, a bracket 201, a vertical beam 203, and a horizontal beam 204. The fixed support frame 101 is installed on the ground, and its upper surface is flat. A base plate 208 is fixedly connected to one side of the upper part of the flat surface, and multiple mounting holes are evenly distributed on the base plate 208. The bracket 201 is a vertical plate frame structure. Its lower end is fixedly connected to the upper surface of the fixed support frame 101 and is located on the right side of the base plate 208. The left side of the bracket 201 is covered by a panel 207. A set of connecting holes is provided on each of the upper two sides of the panel 207, and each set of connecting holes has multiple holes. The testing equipment is installed at the lower middle position of the panel 207. The doorway 205 has vertical beams 203 on both sides, and the lower end of each vertical beam 203 is bolted to the mounting holes on the base plate 208. The upper end of each vertical beam 203 is provided with a positioning slot 233. A horizontal beam 204 is provided above the doorway 205. The two ends of the horizontal beam 204 are bolted to the connecting holes on both sides of the upper part of the panel 207, and the two ends of the horizontal beam 204 are respectively positioned in the positioning slots 233 of the two vertical beams 203. The two vertical beams 203 are fixedly connected to side plates 209 on their opposite sides, and the lower end of the horizontal beam 204 is fixedly connected to a flat plate 210. The side plates 209, the flat plate 210, the base plate 208, and the panel 207 form a closed cavity with an opening only on the left side.

[0025] Specifically, the above structure can adjust the position of the vertical beam 203 and the horizontal beam 204, thereby changing the strength of the combined structure of the bracket 201 and the panel 207. The mounting holes on the base plate 208 and the connecting holes on both sides of the upper part of the panel 207 are used only a portion each time according to the position changes of the horizontal beam 204 and the vertical beam 203. The unused mounting holes and connecting holes are sealed with bolts during the test.

The rectangular frame 231 is vertically installed on the left side of the panel 207, and its lower end is connected to the upper surface of the base plate 208. The positioning rod 232 is fixedly connected to the left side of the rectangular frame 231, and its lower end is connected to the left end face of the base plate 208. The upper end of the positioning rod 232 extends above the rectangular frame 231, forming the positioning slot 233 with the top of the rectangular frame 231. The positioning slot 233 is designed to facilitate assembly and make the combined structure more robust.

[0027] The beam 204 is a horizontal rectangular frame structure. Its right side is connected to the connecting hole on the panel 207, and its left side is connected to the positioning rod 232 by bolts.

[0028] The vertical beam 203 also has a positioning support component 234 installed in its positioning slot 233, which is used to adjust the positioning height of the crossbeam 204. The positioning support component 234 is used to compensate for the gap generated when the crossbeam 204 moves up and down, and together with the side plate 209, the flat plate 210, the first bottom plate 208, and the front panel 207, it forms a closed cavity with an opening only on the left side.

[0029] The positioning support assembly 234 includes multiple U-shaped plates 235 connected in parallel. The right end of each U-shaped plate 235 abuts against the panel 207, and the left end is connected to the positioning rod 232 by bolts.

[0030] A first cooperating beam 205 is connected between the upper left ends of the two vertical beams 203, and a second cooperating beam 206 is connected between the lower left ends of the two vertical beams 203. Both the first cooperating beam 205 and the second cooperating beam 206 are parallel to the horizontal beam 204. The left end face of the horizontal beam 204 is connected to the first cooperating beam 205, and the left end face of the base plate 208 is connected to the second cooperating beam 206.

[0031] The parts of this invention not described in detail are prior art.
