Description

Technical Field

[0001] The invention belongs to the technical field of anti-collision of industrial plant columns, and in particular relates to an anti-collision energy-absorbing pile for a structural column of an industrial plant. Background Art

[0002] At present, in order to meet the requirements of different functional uses, there are widespread cases of mechanical mobile operations in industrial plants. In addition, industrial plants are usually arranged with many structural columns during the design process. Therefore, during the operation of movable machinery, it is inevitable that the structural columns will be hit from different directions, which will cause damage to the structural columns and create safety hazards. Most commonly used industrial plant crash barriers are similar to bridges and roads, which are one-way crash barriers or independent crash barriers are arranged outside the structural columns. The materials are mostly round or square steel pipes, angle steels or pressed steel plates. Since there is a possibility that the structural columns in industrial plants may collide with each other from different directions, and designers usually focus on the simplicity of the structure and economy of the crash prevention device, but often ignore the absorption of energy by the plastic deformation of the device after the collision. At the same time, for the one-way crash barrier, the crash column cross-section is small, resulting in poor overall stability of the system. When the collision is transmitted, if a crash column is damaged and fails, the entire crash barrier will lose its function. These are all problems that need to be solved urgently. Summary of the invention

[0003] The purpose of the present invention is to provide an anti-collision energy-absorbing pile for the structural column of an industrial plant. The present invention is different from a one-way anti-collision device. By forming an anti-collision system, the multi-directional anti-collision capability of the structural column of an industrial plant to cope with impacts from different directions is improved; the present invention can ensure that when an impact occurs, the anti-collision pile forms a three-layer force transmission mechanism to fully improve the safety state of the structural column; the present invention improves the energy absorption effect of the anti-collision pile when an impact occurs from two aspects of material properties and geometric structure.

[0004] In order to achieve the above object, the present invention adopts the following technical solution:

[0005] An anti-collision energy-absorbing pile for a structural column of an industrial plant comprises four anti-collision columns, wherein the anti-collision columns are respectively arranged at four corners at a certain distance outside the structural column to facilitate assembly with adjacent connecting parts of the anti-collision columns to form four anti-collision surfaces, and three anti-collision beams are evenly arranged in the vertical direction between two adjacent anti-collision columns of each anti-collision surface and are connected to the anti-collision columns by high-strength bolts.

[0006] The anti-collision beam is welded with medium-wave galvanized corrugated steel and low-yield point high-strength steel plate to form an outer steel ring beam, and natural rubber is added inside to perform synthetic processing to form a composite anti-collision beam.

[0007] Both ends of the anti-collision beam are tightly connected to the anti-collision column through six high-strength bolts.

[0008] The anti-collision columns are all made of low-yield ratio high-strength steel round steel pipes, and the corrugated steel part of the anti-collision beam is made of medium-wave galvanized corrugated plate with a wave pitch of 200 mm, a wave depth of 55 mm, a wall thickness of 5.0 mm, and a tangent angle of 46.328 degrees.

[0009] After the anti-collision column and the anti-collision beam are completely connected, stiffening ribs are obliquely welded to every two horizontally adjacent anti-collision beams in the internal surrounding area to form an anti-collision system.

[0010] The beneficial effects of the present invention are as follows: since in industrial plants, there is often the possibility of collisions from all directions for structural columns, the present invention can resist multi-directional collisions; the anti-collision beam is welded into an outer steel ring beam by medium-wave galvanized corrugated steel and low-yield strength steel, and natural rubber is added inside the steel ring beam to form a composite anti-collision beam, so the corrugated geometric structure of the corrugated steel can provide plastic deformation ability in the process of responding to the collision, and the internal natural rubber is in a compressed state and deformed during the impact energy transmission, which also provides shock absorption and energy absorption effects from the material properties, thereby ensuring the overall excellent energy absorption performance of the anti-collision pile; the anti-collision column and the anti-collision beam are tightened and connected with high-strength bolts, and oblique support is provided along the oblique welding stiffening ribs on the inner side of every two horizontally adjacent anti-collision beams in the internal enclosed area of ​​the anti-collision column and the anti-collision beam to form an anti-collision system to improve the overall stiffness and stability of the anti-collision pile; during the collision process, the anti-collision pile can form a three-layer force transmission mechanism of "single-side corrugated steel-internal natural rubber-anti-collision columns on both sides" to give full play to the effect of each component itself and the coordinated work of multiple components, thereby improving the overall performance of the anti-collision pile.

DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementations.

[0018] like Figure 1-Figure 5 As shown, an anti-collision energy-absorbing pile for a structural column of an industrial plant includes an anti-collision column 1, an anti-collision beam 2, a stiffening rib 3 and a high-strength bolt 4.

[0019] The anti-collision beam 2 includes a medium-wave galvanized corrugated steel plate 201, a low-yield point high-strength steel plate 202 and a natural rubber 211, which improves the energy absorption capacity of the anti-collision beam from the perspective of geometric structure and material properties.

[0020] The anti-collision beam 2 needs to first place the medium-wave galvanized corrugated steel plate 201 on the outermost side of the anti-collision surface, and arrange the low-yield point high-strength steel plate 202 on the other three sides of the anti-collision beam 2 and weld them with the medium-wave galvanized corrugated steel plate 201 to form a steel ring beam.

[0021] After the steel ring beam is welded, the natural rubber 211 is added to the inside of the steel ring beam, and the natural rubber 211 is synthesized with the steel ring beam to form a composite anti-collision beam, ensuring that when an impact occurs, the impact force is transmitted through a two-layer force transmission mechanism of "single-side corrugated steel-internal natural rubber".

[0022] The two lateral steel plates of the anti-collision beam 2 are each provided with six anti-collision beam bolt holes 203 .

[0023] The anti-collision column 1 includes an anti-collision column body 11 and an anti-collision column bolt hole 12. Six high-strength bolts 4 are screwed into the anti-collision column bolt hole 12 and the anti-collision beam bolt hole 203 between the anti-collision column 1 and the anti-collision beam 2. When the high-strength bolts 4 are all tightened, the connection is completed, and a third-layer force transmission mechanism is formed to continue to transmit the impact force transmitted to the anti-collision beam 2 to the anti-collision columns 1 on both sides. The operation is repeated until all the anti-collision columns 1 and the anti-collision beams 2 in the four anti-collision surfaces are completely connected.

[0024] After the anti-collision column 1 and the anti-collision beam 2 are fully connected, the low-yield point high-strength steel plates 202 of every two horizontally adjacent anti-collision beams 2 inside the formed closed area are welded with oblique stiffening ribs 3 along a certain length to provide oblique support between the anti-collision beams 2, thereby forming an anti-collision system and enhancing the overall stiffness and stability of the anti-collision column.

[0025] The use process of the anti-collision energy-absorbing pile of the industrial plant structure column of the present invention is as follows: first, medium-wave galvanized corrugated steel plate 201 and low-yield strength steel plate 202 are welded into a steel ring beam, and natural rubber 211 is added inside the steel ring beam to be synthesized into a composite anti-collision beam; secondly, all anti-collision beams 2 are tightened by high-strength bolts 4 through the bolt holes reserved for the anti-collision beams 2 and the anti-collision columns 1; finally, when the anti-collision columns 1 and anti-collision beams 2 on the anti-collision surfaces in four directions are all connected, in the inner closed area, oblique stiffening ribs 3 are welded to every two horizontally adjacent anti-collision beams 2 along a certain length of the low-yield high-strength steel plate 202 on the inner side of the anti-collision beam 2.

[0026] The anti-collision column 1 and the anti-collision beam 2 in the present invention are connected by the high-strength bolts 4 and the anti-collision beam 1 is obliquely welded with the stiffening ribs 3 in the internal area to form an anti-collision system, which can ensure that the structural column is in an anti-collision protection state in all directions and realize a multi-directional anti-collision function.

[0027] In this embodiment, in actual installation, the specific dimensions and installation positions of certain main components should be determined according to the actual dimensions of the structural columns to achieve the most optimized anti-collision and energy absorption effect.

[0028] The above-mentioned embodiments of the present invention are not limited to this.
