Description

Technical Field

[0001] This invention belongs to the technical field of civil engineering and mechanical engineering protective equipment, specifically relating to the plastic energy dissipation protective beam structure of vertical shaft derricks. Background Technology

[0002] In modern technological research, accidental impacts on structures are mostly studied and controlled as harmful effects. In the field of civil engineering, once structural components are subjected to accidental external impacts, steel structural components will undergo significant plastic deformation, or even failure, posing safety hazards or even causing collapse of the building. In the field of mechanical engineering, without protective devices, if mechanical lifting equipment collides directly with structural load-bearing components due to overwinding, it will not only cause damage or destruction to the structural load-bearing components, but also damage to the mechanical components of the lifting equipment, resulting in casualties and economic losses.

[0003] Currently, the anti-collision beams used in ground-lifting structures in the coal, power, and metallurgical industries are simply made of materials such as cushioning rubber pads and wood to buffer the impact of lifting equipment. Although these materials have a certain impact-absorbing effect, their ability to dissipate impact energy is limited. A large part of the impact energy is ultimately transferred to the load-bearing components in the form of elastic energy. However, elastic energy can only store energy and cannot dissipate it. This portion of elastic energy stored in the load-bearing components can only be released and dissipated in the form of vibration of the load-bearing components, plastic deformation, and failure of connection nodes. However, this dissipation has already damaged the load-bearing components and even the entire structure, reducing the safety and reliability of the building structure. Summary of the Invention

[0004] The purpose of this invention is to provide a plastic energy dissipation protective beam structure for vertical shaft derricks, which solves the problems of limited plastic energy dissipation and inconvenience in replacing existing anti-collision beams.

[0005] The technical solution adopted in this invention is a plastic energy-dissipating protective beam structure for a vertical shaft derrick, including a plastic energy-dissipating component. A supporting component is fixedly connected to the upper side of the plastic energy-dissipating component by several bolts. Soft steel energy-dissipating supports are fixedly connected to both sides of the supporting component. The other side of the two soft steel energy-dissipating supports is fixedly connected to a steel column. The structure also includes several buffer supports, which are fixedly connected to the lower side of the steel beam. The steel beam is located above the supporting component, and the buffer supports correspond to the supporting component.

[0006] The invention is further characterized by:

[0007] The plastic energy-dissipating component comprises several energy-dissipating component units, which are arranged side by side and fixed to the supporting component by several bolts.

[0008] The energy-dissipating component unit includes a plastic energy-dissipating roof plate, which is fixed to the supporting component by several bolts. A corresponding plastic energy-dissipating soft steel plate is vertically fixed to the lower end face of the plastic energy-dissipating roof plate, and the two plastic energy-dissipating soft steel plates are jointly fixed to the impact-resistant unit.

[0009] The impact-resistant unit includes an isosceles triangular frame consisting of an impact-resistant base plate and two plastic energy-dissipating guide plates connected end to end.

Symmetrical second plastic energy-dissipating reinforcing plates are provided on both sides of the first plastic energy-dissipating reinforcing plate inside the isosceles triangular frame.

[0010] The supporting components include a base plate and a top plate. The base plate and the plastic energy-dissipating top plate are fixed together by several bolts. A web plate and two reinforcing plates are fixed between the base plate and the top plate. The two reinforcing plates are symmetrically arranged about the web plate.

[0011] The mild steel energy-dissipating support includes a first mild steel energy-dissipating support base plate and a second mild steel energy-dissipating support base plate. The first mild steel energy-dissipating support base plate is fixedly connected to the base plate of the supporting member and the top plate of the supporting member, respectively. The second mild steel energy-dissipating support base plate is fixedly connected to the steel column. A plurality of perforated mild steel energy-dissipating plates are provided between the first mild steel energy-dissipating support base plate and the second mild steel energy-dissipating support base plate.

[0012] The buffer support includes a sleeve, one end of which is fixedly connected to a sleeve base plate, and the other end of which is fixedly connected to a sleeve end plate. A polyurethane spring is fixedly connected to the sleeve base plate inside the sleeve. The sleeve end plate has a through hole, and a sleeve rod is provided in the through hole.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] The vertical shaft derrick plastic energy dissipation protection beam structure provided by this invention, such as Figure 1 As shown, the system includes a plastic energy-dissipating component 1. A supporting component 2 is fixed to the upper side of the plastic energy-dissipating component 1 by several bolts. Soft steel energy-dissipating supports 3 are fixed to both sides of the supporting component 2. The other sides of the two soft steel energy-dissipating supports 3 are fixed to steel columns. The system also includes several buffer supports 4, which are fixed to the lower side of a steel beam. The steel beam is positioned above the supporting component 2, and the buffer supports 4 correspond to the supporting component 2. When the supporting component 2 undergoes a certain deformation, it will contact the buffer supports 4 at the bottom of the steel beam, preventing damage to the steel beam. Figure 2As shown, the plastic energy-dissipating component 1 includes several energy-dissipating component units 23, which are arranged side by side and fixed to the supporting component 2 by several bolts. Each energy-dissipating component unit 23 includes a plastic energy-dissipating top plate 9, which is fixed to the supporting component 2 by several bolts. A corresponding plastic energy-dissipating soft steel plate 8 is vertically fixed to the lower end face of the plastic energy-dissipating top plate 9. The two plastic energy-dissipating soft steel plates 8 are jointly fixed to the impact-resistant unit. The impact-resistant unit includes an isosceles triangular frame composed of an impact-resistant bottom plate 5 and two plastic energy-dissipating guide plates 7 connected end to end. The two plastic energy-dissipating guide plates 7 are fixed to the two plastic energy-dissipating soft steel plates 8 respectively. It also includes a first plastic energy-dissipating reinforcing plate 6, which is fixed to the isosceles triangle. Within the frame, the first plastic energy-dissipating reinforcing plate 6 is positioned at the height of the isosceles triangle. Symmetrical second plastic energy-dissipating reinforcing plates 24 are located on both sides of the first plastic energy-dissipating reinforcing plate 6 within the isosceles triangle frame to enhance rigidity and fix the guide plate 7. The guide plate 7 is used to change the direction of the impact, making it easier for shear stress and normal stress to be generated within the two plastic energy-dissipating soft steel plates 8, thus promoting energy-dissipating plastic deformation. The supporting member 2 includes a supporting member base plate 10 and a supporting member top plate 13. The supporting member base plate 10 and the plastic energy-dissipating top plate 9 are fixedly connected by several bolts. A supporting member web plate 11 and two supporting member reinforcing plates 12 are fixedly connected between the supporting member base plate 10 and the supporting member top plate 13. The two supporting member reinforcing plates 12 are symmetrically arranged about the supporting member web plate 11. Figure 3 As shown, the soft steel energy-dissipating support 3 includes a first soft steel energy-dissipating support base plate 14 and a second soft steel energy-dissipating support base plate 25. The first soft steel energy-dissipating support base plate 14 is fixedly connected to the support member base plate 10 and the support member top plate 13, respectively. The second soft steel energy-dissipating support base plate 25 is fixedly connected to the steel column for easy replacement later. A plurality of perforated soft steel energy-dissipating plates 15 are provided between the first soft steel energy-dissipating support base plate 14 and the second soft steel energy-dissipating support base plate 25. Figure 4 As shown, the buffer support 4 includes a sleeve 17. One end of the sleeve 17 is fixedly connected to a sleeve base plate 20, and the other end of the sleeve 17 is fixedly connected to a sleeve sealing plate 16. A polyurethane spring 19 is fixedly connected to the sleeve base plate 20 inside the sleeve 17. The sleeve sealing plate 16 has a through hole, and a sleeve rod 18 is provided in the through hole. The sleeve rod 18 is located inside the polyurethane spring 19. A limiting ring 22 is fitted on the outer wall of the sleeve rod 18 near the sleeve sealing plate 16. The limiting ring 22 is located inside the sleeve 17 and is engaged with the other end of the polyurethane spring 19. A buffer rubber pad 21 is fixedly connected to the end of the sleeve rod 18 away from the sleeve base plate 20 to buffer the impact. When the sleeve rod 18 slides, the limiting ring 22 begins to compress the polyurethane spring 19 to buffer the displacement speed of the sleeve rod 18.

[0022] The working principle of the vertical shaft derrick plastic energy-dissipating protective beam structure provided by this invention is as follows: When the hoisting device over-winds and impacts the protective beam structure, it first impacts the plastic energy-dissipating component 1. The guide plate 7 inside the plastic energy-dissipating component 1 changes the direction of the impact, causing shear stress and normal stress to be generated in the two plastic energy-dissipating soft steel plates 8, making it easier to generate energy-dissipating plastic deformation and consume part of the impact energy. The remaining impact energy is transferred to the support component 2. The soft steel energy-dissipating supports 3 fixed to both sides of the support component 2 further consume part of the impact energy through several perforated soft steel energy-dissipating plates 15. When the impact energy is not completely consumed, the soft steel energy-dissipating support 3 further dissipates the impact energy. As the steel energy-dissipating support 3 continues to deform, the supporting member 2 comes into contact with several buffer supports 4. The sleeve rod 18 in the several buffer supports 4 compresses the polyurethane spring 19 through the limiting ring 22. The remaining impact energy is converted into elastic potential energy and stored in the polyurethane spring 19 in the buffer support 4. When the impact energy is completely dissipated, the compressed polyurethane spring 19 returns to the undeformed state from the compressed state, releases the internal elastic energy, and pushes the supporting member 2 in the opposite direction. The supporting member 2 deforms in the opposite direction, driving the soft steel energy-dissipating supports 3 on both sides, and dissipating the final remaining elastic energy through the plastic energy-dissipating soft steel plate 8 of the soft steel energy-dissipating support 3.
