Description

Technical Field

[0001] This invention relates to the technology of strengthening nodes of power transmission towers, and in particular to a multi-energy-dissipating strengthening device and method for K-type nodes of steel pipe towers. Background Technology

[0002] Transmission towers are subjected to loads such as earthquakes, icing, or strong winds during their service life, and the nodes of the transmission towers are easily damaged by external forces. The nodes are very important for the safety of the transmission towers. Once the nodes fail, they will not be able to provide sufficient restraint, resulting in the destruction of the structural system.

[0003] Currently, the main reinforcement measures for transmission tower nodes are to install reinforcement devices at critical nodes to improve their load-bearing capacity. However, the main materials at critical nodes are also prone to local buckling due to insufficient load-bearing capacity. Traditional node reinforcement measures only install reinforcement devices at critical nodes and cannot provide overall reinforcement and support, resulting in poor protection capabilities. Furthermore, under extreme loads or seismic conditions, traditional node reinforcement measures do not have energy dissipation effects and have poor self-regulation capabilities. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a multi-energy-dissipating reinforcement device and method for K-type nodes of steel pipe towers. This invention enables reinforcement of existing nodes on transmission towers without damage, offering advantages such as high reliability, ease of operation, and convenient construction. Furthermore, it features a simple structure, good overall integrity, and wide applicability. This invention can reinforce important nodes and main materials at nodes on transmission towers, maintaining good overall integrity and improving the reinforcement efficiency of transmission tower nodes. Simultaneously, the use of an energy-dissipating device enhances its adaptability.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a multi-energy-dissipating reinforcement device for K-type nodes of steel pipe towers, employing the following technical solution:

[0006] A multi-energy-dissipating reinforcement device for K-type nodes of steel pipe towers includes an upper reinforcement structure, a lower reinforcement structure, an upper reinforcement telescopic plate, and a lower reinforcement telescopic plate. The upper and lower reinforcement structures are symmetrically arranged vertically and each includes a reinforcement annular plate, a reinforcement sleeve without an annular plate, a reinforcement sleeve with an annular plate, and a connecting rod. The upper and lower surfaces of the reinforcement annular plate are respectively attached to the annular plate to be reinforced and the reinforcement sleeve with an annular plate. The reinforcement sleeve without an annular plate and the reinforcement sleeve with an annular plate are placed on the main material to be reinforced, and are open to traffic. The upper and lower reinforcing structures are connected together by the connecting rods; the upper reinforcing telescopic plate is attached to the upper annular plate to be reinforced and connected to the upper reinforcing structure, applying a clamping force to the upper annular plate to be reinforced; the lower reinforcing telescopic plate is attached to the lower annular plate to be reinforced and connected to the lower reinforcing structure, applying a clamping force to the lower annular plate to be reinforced; the upper and lower reinforcing telescopic plates are fixed together after being inserted, and energy dissipators are provided on both the upper and lower reinforcing telescopic plates.

[0007] As a further technical solution, the upper reinforcement structure has an annular plate at the bottom of the annular plate reinforcement sleeve, and the upper reinforcement telescopic plate has an annular plate at the top, with the two annular plates connected by bolts.

[0008] As a further technical solution, the lower reinforcement structure has an annular plate at the top of the annular plate reinforcement sleeve, and the lower reinforcement telescopic plate has an annular plate at the bottom, with the two annular plates connected by bolts.

[0009] As a further technical solution, the connecting rod is fitted with a sleeve without an annular plate and a sleeve with an annular plate in a concave-convex fit.

[0010] As a further technical solution, one end of the energy dissipator on the upper reinforced telescopic plate is fixed to the upper reinforced telescopic plate, and the other end is fixed to the lower reinforced telescopic plate. Similarly, one end of the energy dissipator on the lower reinforced telescopic plate is fixed to the lower reinforced telescopic plate, and the other end is fixed to the lower reinforced telescopic plate.

[0011] As a further technical solution, the energy consuming device includes a first energy consuming device sleeve, a second energy consuming device sleeve, a force transmission rod, a soft steel rod, and a spring; the first energy consuming device sleeve and the second energy consuming device sleeve are connected, the force transmission rod, the soft steel rod, and the spring are located in the space after the first energy consuming device sleeve and the second energy consuming device sleeve are connected, and the end of the force transmission rod with the bolt hole is located outside the second energy consuming device sleeve; a rubber slider is fixed on the force transmission rod.

[0012] As a further technical solution, the bottom of the second energy consumer sleeve is provided with a switchable through hole.

[0013] As a further technical solution, the insertion height of the upper and lower reinforcing telescopic plates is adjustable.

[0014] As a further technical solution, the thickness of the reinforcing annular plate is less than or equal to the thickness of the annular plate to be reinforced.

[0015] To achieve the above objectives, in a second aspect, the present invention also provides a method for multi-energy-dissipating reinforcement of K-type nodes in steel pipe towers, employing the following technical solution:

[0016] The outer sides of the reinforcing annular plate and the annular plate to be reinforced are attached together, and the annular plate with the annular plate reinforcing sleeve is attached to the reinforcing annular plate.

[0017] The main material is reinforced by clamping the non-ring plate reinforcing sleeve and the ring plate reinforcing sleeve of the upper reinforcement structure and the non-ring plate reinforcing sleeve and the ring plate reinforcing sleeve of the lower reinforcement structure with connecting rods, and connecting the two connecting rods. The ring plate of the upper reinforcement telescopic plate is attached to the inner side of the upper ring plate to be reinforced; the ring plate of the lower reinforcement telescopic plate is attached to the inner side of the lower ring plate to be reinforced.

[0018] The lengths of the upper and lower reinforcing telescopic plates are adjusted and fixed. The annular plate with the annular plate reinforcing sleeve, the annular plate of the upper reinforcing telescopic plate, and the annular plate of the lower reinforcing telescopic plate fix the reinforcing annular plate and the annular plate to be reinforced.

[0019] Install energy dissipators on the upper and lower reinforced expansion plates;

[0020] By adjusting the nuts on the bolts between the annular plate of the annular plate reinforced sleeve, the annular plate of the upper reinforcing telescopic plate, and the annular plate of the lower reinforcing telescopic plate, the reinforcing annular plate and the annular plate to be reinforced are further clamped.

[0021] The beneficial effects of this invention are:

[0022] When the original main material is subjected to lateral tensile or compressive forces, for the cross-section of the main material, adding this reinforcement device can effectively disperse the stress on the original main material to the non-ring plate reinforcement sleeve and the ring plate reinforcement sleeve. For the weak section of the original main material, the stress can be effectively dispersed to the non-ring plate reinforcement sleeve, the ring plate reinforcement sleeve, and the connecting rod, thereby reducing the stress on the original main material and preventing buckling. For the ring plate to be reinforced, adding this reinforcement device can effectively disperse the stress of the ring plate to be reinforced to the reinforced ring plate, the ring plate reinforcement sleeve, and the ring plate with the ring plate reinforcement sleeve and the lower reinforcement expansion plate. This improves the load-bearing capacity and stability of the original main material and the steel pipe tower joint. Under seismic action or extreme load, the energy dissipator will participate in the operation. It dissipates energy by generating frictional resistance between the rubber slider and the inner wall of the second energy dissipator sleeve, as well as through the spring and soft steel rod. When the annular plates on the upper and lower reinforced telescopic plates suddenly deform slightly, the force can be transmitted to the main plates of the upper and lower reinforced telescopic plates, and then to the rib plate (which has high rigidity and is not easily damaged). Subsequently, the spring will work to reset it, thus playing the role of energy dissipation and buffering.

[0023] The node reinforcement device of this invention has a reasonable structural design. Compared with existing technologies, it not only enhances the load-bearing capacity of the nodes but also the load-bearing capacity of the main materials. This invention can act as an energy-dissipating buffer during earthquakes or extreme loads, effectively improving the load-bearing capacity and overall stability of transmission tower nodes. This invention eliminates the need for temporary dismantling of existing load-bearing components, avoiding complex stress redistribution in localized areas. It has the advantages of simple construction, convenient maintenance, and significant effects. Attached Figure Description

[0034] The present disclosure will be further described below with reference to the accompanying drawings and embodiments.

[0035] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0036] With rapid economic development, the demand for electricity has increased dramatically, making electrical energy a necessity for social development. The nodes of long-span transmission towers are critical load-bearing components, highly susceptible to failure under loads from earthquakes, icing, or strong winds, leading to transmission line damage. This severely impacts people's normal lives and even disaster relief efforts. Therefore, improving the power grid's ability to withstand natural disasters and reinforcing transmission towers after their service life are crucial for the safe and stable operation of the power grid and the security of power supply under severe natural disasters.

[0037] This embodiment proposes a multi-energy-dissipating reinforcement device for K-type nodes of steel pipe towers, including a reinforcing annular plate, a reinforcing sleeve, a connecting rod, and a reinforcing telescopic plate. The reinforcing annular plate is fitted to the annular plate to be reinforced. The reinforcing sleeve is placed on the upper and lower sides of the main material to be reinforced. The connecting rod, through its convex plate passing through the groove of the reinforcing sleeve, can better fit with the reinforcing sleeve. The upper and lower connecting rods are connected by high-strength bolts. The reinforcing telescopic plate is divided into upper and lower parts, both of which fit to the annular plate to be reinforced. The lower reinforcing telescopic plate main board can freely pass through the upper reinforcing telescopic plate main board, and the upper reinforcing telescopic plate... The main board has five pairs of bolt holes. Once the positions of the upper and lower reinforcing telescopic plates are determined, the bolts on the main board of the upper reinforcing telescopic plate can be tightened to fix the length of the reinforcing telescopic plate. The annular plates of the reinforcing sleeve and the reinforcing telescopic plate clamp the reinforcing annular plate and the annular plate to be reinforced. High-strength bolts apply reinforcing force to the reinforcing annular plate and the annular plate to be reinforced through the bolt holes of the annular plates of the reinforcing sleeve and the reinforcing telescopic plate. Bolt holes are present at the connection points at both ends of the energy dissipator. Bolt holes are also present at the corresponding connection points of the lower reinforcing telescopic plate annular plate, the main board, and the upper telescopic plate annular plate. High-strength bolts can fix the energy dissipator through these bolt holes. This embodiment eliminates the need for temporary disassembly of the original load-bearing components, avoiding the problem of complex stress redistribution in localized areas that could lead to a dangerous state for the transmission tower during reinforcement.

[0038] Furthermore, the side wall of the reinforcing sleeve is provided with a groove, which can better fit with the reinforcing plate; one side of the reinforcing node is provided with an annular plate and bolt holes, which can serve as a clamping plate for the reinforcing annular plate.

[0039] Furthermore, the inner walls on both sides of the connecting rod are provided with protruding plates, which can better fit with the sleeve, and there are bolt holes at the bottom of the connecting rod.

[0040] Furthermore, the length of the reinforced telescopic plate can be changed. After the reinforced telescopic plate is adjusted to the correct position, the final length can be fixed by tightening the bolts on the main board.

[0041] Furthermore, the reinforcing ring plate is determined according to the ring plate to be reinforced, so that the reinforcing ring plate can fit into the ring plate to be reinforced, and the thickness of the reinforcing ring plate is less than or equal to the thickness of the ring plate to be reinforced.

[0042] Furthermore, the reinforcing telescopic plate has an annular plate and bolt holes, which can be used as a clamping plate for reinforcing the annular plate; the annular plate of the upper reinforcing telescopic plate, the annular plate of the lower reinforcing telescopic plate, and the main plate are provided with connection points at corresponding positions.

[0043] Furthermore, the high-strength bolts can apply a reinforcing force to the reinforcing annular plate and the annular plate to be reinforced through the bolt holes of the annular plate of the sleeve and the bolt holes of the reinforcing telescopic plate; the high-strength bolts are connected to the reinforcing sleeve through the bolt holes of the upper and lower reinforcing plates.

[0044] Furthermore, the nodes at the corresponding positions of the reinforced telescopic plate can be connected to the nodes at both ends of the energy dissipator.

[0045] Furthermore, the energy dissipator includes a first energy dissipator sleeve, a second energy dissipator sleeve, a force transmission rod, a soft steel rod (made of soft steel, which can also exert a good energy dissipation effect under small displacement), and a spring; the first energy dissipator sleeve and the second energy dissipator sleeve are connected, the force transmission rod, the soft steel rod and the spring are located in the space after the first energy dissipator sleeve and the second energy dissipator sleeve are connected, and the end of the force transmission rod with bolt holes is located outside the second energy dissipator sleeve; the bottom of the force transmission rod is provided with a gasket to fix a rubber slider, the rubber slider is provided with a through hole, and the bottom of the second energy dissipator sleeve is also provided with a switchable through hole.

[0046] The present invention will now be described in detail with reference to the accompanying drawings:

[0047] Example 1:

[0048] like Figure 1 and Figure 2 As shown, this embodiment provides a multi-energy-consuming reinforcement device for K-type nodes of steel pipe towers, including two non-annular plate reinforcement sleeves 2-1, two annular plate reinforcement sleeves 2-2, two connecting rods 3, two reinforcement annular plates 4, two upper reinforcement telescopic plates 6-1, two lower reinforcement telescopic plates 6-2, and four energy-consuming devices 10.

[0049] One non-ring plate reinforcing sleeve 2-1, one ring plate reinforcing sleeve 2-2, a connecting rod 3, and a reinforcing ring plate 4 form the upper reinforcing structure. The other non-ring plate reinforcing sleeve 2-1, one ring plate reinforcing sleeve 2-2, a connecting rod 3, and a reinforcing ring plate 4 form the lower reinforcing structure. The upper reinforcing structure is connected to two upper reinforcing telescopic plates 6-1, and the lower reinforcing structure is connected to two lower reinforcing telescopic plates 6-2. The corresponding upper reinforcing telescopic plates 6-1 are connected to... The lower reinforcing telescopic plates 6-2 are connected by bolts to form a telescopic structure. Two upper reinforcing telescopic plates 6-1 and two lower reinforcing telescopic plates 6-2 form two sets of telescopic structures. These two sets of telescopic structures are located on both sides of the reinforcing plate 8. One set of telescopic structures is equipped with two energy dissipators 10, and the ends of the force transmission rods of the two energy dissipators 10 are located at the same node, both on the main plate of the lower reinforcing telescopic plate 6-2. Furthermore, the connecting rod 3 of the upper reinforcing structure is connected to the connecting rod 3 of the lower reinforcing structure. Specifically:

[0050] The two reinforcing annular plates 4 are respectively attached to the outer sides of the upper and lower annular plates 5 to be reinforced;

[0051] The axial direction of the non-annular plate reinforcing sleeve 2-1 and the annular plate reinforcing sleeve 2-2 of the upper and lower reinforcing structures is consistent with the axial direction of the original main material 1. The annular plate reinforcing sleeve 2-2 of the upper reinforcing structure is placed on the upper side of its corresponding reinforcing annular plate 4, and the annular plate reinforcing sleeve 2-2 of the lower reinforcing structure is placed on the lower side of its corresponding reinforcing annular plate 4. The non-annular plate reinforcing sleeve 2-1 and the annular plate reinforcing sleeve 2-2 are arranged around the outer ring of the original main material 1. The connecting rod 3 connects its corresponding non-annular plate reinforcing sleeve 2-1 and the annular plate reinforcing sleeve 2-2, and is connected to the connecting rod 3 of the other reinforcing structure by high-strength bolts 9.

[0052] After the upper reinforcing telescopic plate 6-1 and the lower reinforcing telescopic plate 6-2 are positioned, their lengths are fixed by tightening high-strength bolts. The two ends of the energy dissipator 10 are connected to the connection points of the upper reinforcing telescopic plate 6-1 and the lower reinforcing telescopic plate 6-2. The annular plate bolt holes of the annular plate reinforcing sleeve 2-2 correspond to the annular plate bolt holes of the upper reinforcing telescopic plate 6-1 or the lower reinforcing telescopic plate 6-2. After being connected by high-strength bolts, a reinforcing force can be applied to the reinforcing annular plate 4 and the annular plate 5 to be reinforced.

[0053] like Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the non-annular plate reinforcing sleeve 2-1 has grooves I 2-1-1 on both sides, and the annular plate reinforcing sleeve 2-2 has grooves II 2-2-1 on both sides, which facilitates the fit and connection with the protrusion 3-1 of the connecting rod 3. The annular plate reinforcing sleeve 2-2 has an annular plate I 2-2-2, and the outer diameter of the annular plate I 2-2-2 is larger than that of the reinforcing annular plate 4 and the annular plate 5 to be reinforced, so it can be used as a clamping plate for the reinforcing annular plate 4 and the annular plate 5 to be reinforced. The annular plate of the annular plate reinforcing sleeve 2-2 has bolt holes I 2-2-3, which can be used to further reinforce the reinforcing annular plate 4 and the annular plate 5 to be reinforced by high-strength bolt connection.

[0054] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the inner side of the connecting rod is provided with a protruding plate 3-1, which better fits with the grooves I 2-1-1 and II 2-2-1 of the sleeve without an annular plate and the sleeve with an annular plate 2-2. The end is provided with a bolt hole II 3-2, and a high-strength bolt is connected through the bolt holes II 3-2 of the upper and lower reinforcing plates, which can reinforce the original main material 1.

[0055] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the upper reinforcing telescopic plate 6-1 and the lower reinforcing telescopic plate 6-2 are provided with annular plate II 6-1-1 and annular plate III 6-2-1, and their outer diameters are larger than the outer diameters of the reinforcing annular plate 4 and the annular plate 5 to be reinforced. They can serve as clamps for the reinforcing annular plate 4 and the annular plate 5 to be reinforced. The annular plates of the upper reinforcing telescopic plate 6-1 and the lower reinforcing telescopic plate 6-2 are provided with bolt holes III 6-1-4 and VI 6-2-4, which can be connected to the annular plate I 2-2-2 with the annular plate reinforcing sleeve 2-2 by high-strength bolts to further reinforce the reinforcing annular plate 4 and the annular plate 5 to be reinforced.

[0056] The upper reinforcing telescopic plate 6-1 has a connection point I 6-1-3 on the annular plate II 6-1-1, and a bolt hole IV 6-1-5 on the connection point I 6-1-3; the lower reinforcing telescopic plate 6-2 has a connection point III 6-2-6 on the annular plate III 6-2-1, and a bolt hole VIII 6-2-7 on the connection point III 6-2-6; and the lower reinforcing telescopic plate main plate 6-2-2 has a connection point II 6-2-3, and a bolt hole VII 6-2-5 on the connection point II 6-2-3.

[0057] One end of the upper energy dissipator 10 is connected to bolt hole IV 6-1-5, and the other end is connected to bolt hole VII 6-2-5. One end of the lower energy dissipator 10 is connected to bolt hole VIII 6-2-7, and the other end is connected to bolt hole VII 6-2-5.

[0058] The lower reinforcing telescopic plate main board 6-2-2 is inserted into the upper reinforcing telescopic plate main board 6-1-2. The upper reinforcing telescopic plate main board 6-1-2 is provided with five pairs of bolt holes V 6-1-6, which can be tightened to fix the length of the upper reinforcing telescopic plate 6-1 and the lower reinforcing telescopic plate 6-2.

[0059] like Figure 6 As shown, in this embodiment, the energy consumer 10 includes a first energy consumer sleeve 10-1, a second energy consumer sleeve 10-2, a force transmission rod 10-3, a soft steel rod 10-4, and a spring 10-6.

[0060] One end of the first energy consumer sleeve 10-1 is connected to one end of the second energy consumer sleeve 10-2;

[0061] After the two parts are connected, a cavity is formed. The other end of the second energy consumer sleeve 10-2 is provided with a switchable through hole II 10-10. A spring 10-6, a soft steel rod 10-4, a spring 10-6, and a force transmission rod 10-3 are arranged in sequence in the cavity. The end of the force transmission rod 10-3 with a bolt hole passes through the through hole II 10-10 and extends to the outside of the second energy consumer sleeve 10-2. The two ends of the soft steel rod 10-4 are symmetrically and coaxially arranged with springs 10-6, which are located in trapezoidal slots 10-5. The trapezoidal slots are respectively located at the bottom of the first energy consumer sleeve 10-1 and the end of the force transmission rod 10-3. The end of the force transmission rod 10-3 is provided with a gasket to fix the rubber slider 10-7. The rubber slider 10-7 is provided with a through hole I 10-9, through which the force transmission rod 10-3 passes.

[0062] Specifically, the energy consumer 10 can be configured as multiple units, and in this embodiment, it can be configured as four units. Each energy consumer 10 consists of two sleeves, a force transmission rod 10-3, a soft steel rod 10-4, and a spring 10-6. The two sleeves are threaded (one end of the first energy consumer sleeve 10-1 is provided with an internal thread, and one end of the second energy consumer sleeve 10-2 is provided with an external thread to achieve a connection). The installation and energy consumption effect of the energy consumer 10 can be adjusted by rotating the sleeves. The rubber slider 10-7 is in close contact with the inner wall of the second energy consumer sleeve 10-2. After the positions of the force transmission rod 10-3, the first energy consumer sleeve 10-1, and the second energy consumer sleeve 10-2 are fixed, the switchable through hole II 10-10 at the bottom of the second energy consumer sleeve 10-2 can be closed. Energy consumption is achieved by the frictional resistance generated between the rubber slider 10-7 and the inner wall of the second energy consumer sleeve 10-2, and by the spring 10-6 and the soft steel rod 10-4.

[0063] like Figure 1 and Figure 2 As shown, in this embodiment, the energy consumer 10 can be connected to the annular plate of the reinforced telescopic plate via bolt holes IV 6-1-5 and bolt holes VII 6-2-5 at both ends.

[0064] The working principle of this embodiment is as follows:

[0065] When the original main member 1 is subjected to lateral tensile or compressive forces, for the cross-section of the main member, adding this reinforcement device can effectively disperse the stress on the original main member 1 to the non-annular plate reinforcement sleeve 2-1 and the annular plate reinforcement sleeve 2-2. For the weak section of the original main member 1, the stress can be effectively dispersed to the non-annular plate reinforcement sleeve 2-1, the annular plate reinforcement sleeve 2-2, and the connecting rod 3, thereby reducing the stress on the original main member 1 and preventing buckling. For the annular plate 5 to be reinforced, adding this reinforcement device can effectively disperse the stress of the annular plate to be reinforced to the reinforced annular plate 4, the annular plate reinforcement sleeve 2-2, the annular plate reinforcement sleeve 6-1, and the lower reinforcement telescopic plate 6-2. This improves the bearing capacity and stability of the original main member 1 and the steel pipe tower node. Under seismic action or extreme load, the energy dissipator 10 will participate in the operation. The frictional resistance generated by the rubber slider 10-7 and the inner wall of the second energy dissipator sleeve 10-2, as well as the spring 10-6 and the soft steel rod 10-4, will dissipate energy. When the annular plate II 6-1-1 on the upper reinforcing telescopic plate and the annular plate III 6-2-1 on the lower reinforcing telescopic plate suddenly deform, the force can be transmitted to the main plate 6-1-2 of the upper reinforcing telescopic plate and the main plate 6-2-2 of the lower reinforcing telescopic plate, and then to the rib plate 8 (which has high rigidity and is not easy to be damaged). Subsequently, the spring 10-6 will work to reset it, playing the role of energy dissipation and buffering.

[0066] The device has a reasonable structural design, which, compared with existing technologies, not only enhances the load-bearing capacity of the nodes but also the load-bearing capacity of the main materials.

[0067] This device acts as an energy-dissipating buffer under seismic action or extreme loads, effectively improving the load-bearing capacity and overall stability of transmission tower nodes.

[0068] This device eliminates the need for temporary disassembly of existing load-bearing components, avoids complex stress redistribution in localized areas, and boasts advantages such as simple construction, convenient maintenance, and significant effectiveness.

[0072] The main material is reinforced by the non-ring plate reinforcing sleeve and the ring plate reinforcing sleeve clamped by the device reinforcing plate, and the ring plate of the reinforcing telescopic plate is attached to the inner side of the ring plate to be reinforced.

[0073] The length of the telescopic plate is fixed by adjusting the bolts on the main board of the upper telescopic plate of the device. The annular plate with the annular plate reinforcement sleeve and the annular plate of the telescopic plate fix the reinforcing annular plate and the annular plate to be reinforced. The nodes of the annular plate on the telescopic plate and the nodes of the main board on the telescopic plate are connected to the energy dissipator.

[0074] By adjusting the nuts on the bolts between the annular plate of the annular plate reinforced sleeve and the annular plate on the reinforced telescopic plate, the reinforced annular plate and the annular plate to be reinforced are further clamped.
