Description

Technical Field

[0002] This invention relates to the technical field of tunnel construction equipment, specifically to a rapid installation support assembly for composite panels used in tunnel evacuation platforms. Background Technology

[0004] With the rapid development of my country's transportation infrastructure, tunnel projects such as railways, highways, and subways are increasing. As a crucial passageway for personnel escape and rescue in emergencies, the safety and stability of evacuation platforms within tunnels are paramount. Currently, most tunnel evacuation platforms are constructed using composite panels, which are typically fixed to the tunnel sidewalls by support components.

[0005] Currently, when installing composite panels, a trolley is typically used inside the tunnel to move the panel onto a support assembly. Workers stand on the trolley, place the composite panel on the support assembly, and then push it to the installation position. However, because the composite panel is quite heavy, and there is significant resistance between the panel and the support assembly during the pushing process, the panel is prone to shifting relative to the support assembly due to this resistance, requiring workers to adjust the installation position multiple times. This results in both high labor intensity for workers and low installation efficiency.

[0006] Therefore, there is an urgent need for a support device that can assist in the quick, labor-saving, and safe installation of composite panels. Summary of the Invention

[0008] The main objective of this invention is to provide a quick-installation support assembly for composite panels in tunnel evacuation platforms. This aims to solve the problems in related technologies, such as the high resistance between the heavy composite panels and the support assembly, which leads to high labor intensity for workers during installation, and the low installation efficiency caused by workers having to repeatedly calibrate the position of the composite panels due to force displacement.

[0009] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0010] The tunnel evacuation platform composite panel quick-installation support assembly includes a support rod connected to the tunnel sidewall. The support rod has clearance grooves and receiving grooves, and the support rod also features:

[0011] The guiding assembly includes a guide member slidably disposed in the relief groove and a guide post rotatably connected to the guide member; the guide member is used to support the end of the composite panel and guide its movement direction, and the outer peripheral surface of the guide post makes rolling contact with the bottom of the relief groove to reduce the resistance when the guide member moves along the support rod.

[0012] The limiting assembly includes a drive rod rotatably disposed in a receiving groove, an extension plate fixedly disposed on the drive rod, a limiting shaft disposed on the end of the extension plate away from the drive rod, a limiting post rotatably disposed on the limiting shaft, and a limiting plate disposed at a preset angle with the extension plate.

[0013] An adjustment assembly, connected to the drive rod, is used to limit and release the rotation of the drive rod relative to the support rod;

[0014] The limiting component has an extended state and a retracted state. In the extended state, the extension plate drives the limiting post to extend out of the receiving groove to support the bottom of the composite plate and cooperate with the guiding component to tilt the composite plate. The extension plate is tilted towards the tunnel sidewall.

[0015] When the guide moves to the extreme position at one end of the tunnel sidewall and the limiting component is in the retracted state, the limiting column retracts into the receiving groove, the composite plate is laid flat on the support rod, and the limiting plate abuts against the end of the composite plate.

[0016] Specifically, each support rod is provided with a set of guide components, limit components and adjustment components on opposite sides along the tunnel extension direction; each composite plate spans between two adjacent support rods and cooperates with the guide components and limit components on the opposite sides of the two adjacent support rods.

[0017] Specifically, the guide includes a support plate, limiting side plates located on both sides of the support plate and extending downward, and a connecting shaft located between the two limiting side plates, with the guide column rotating coaxially on the connecting shaft.

[0018] Specifically, there are two sets of connecting shafts and guide columns. The two connecting shafts are distributed at intervals along the extension direction of the support rod, and the axial direction of the connecting shafts is perpendicular to the extension direction of the support rod.

[0019] Specifically, the upper surface of the support plate coincides with the upper surface of the non-yielding groove of the support rod.

[0020] Specifically, the adjustment assembly includes an adjustment block coaxially mounted on the drive rod, a limiting block mounted on the adjustment block, and a baffle slidably mounted on the support rod, with a limiting groove provided on the limiting block;

[0021] When the baffle is inserted into the limiting groove, it restricts the rotation of the drive rod. When the baffle is removed from the limiting groove, it releases the restriction on the rotation of the drive rod.

[0022] Specifically, there are two limit blocks, which are distributed at intervals along the circumference of the drive rod. Each limit block has a limit groove so that the limit component can be limited by the baffle when it is in the extended or retracted state.

[0023] Specifically, the axis of the drive rod is set parallel to the axis of the connecting shaft.

[0024] Specifically, a positioning plate is fixedly installed on the side of the support plate near the tunnel sidewall. The positioning plate is used to limit the position of the composite plate on the support plate.

[0025] Specifically, the limiting plate has mounting holes for inserting external tools to drive the limiting plate to rotate.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. By guiding the movement of the composite panel through the guide component, the installation accuracy of the composite panel can be improved, and the displacement of the composite panel relative to the installation position during the movement can be avoided, which would require repeated adjustments by the staff, thus simplifying the installation steps.

[0028] 2. By designing the guiding and limiting components—namely, the support plate and the limiting posts—the composite panel is tilted during installation, making it easier for workers to push it. Simultaneously, the rolling design of the guiding and limiting posts reduces resistance during panel movement, making installation easier and less strenuous for operators.

[0029] 3. The automatic rotation and storage of the limiting components after unlocking ensures that the composite panel can be accurately and flatly positioned, and the limiting plate provides lateral limiting, ensuring the structural stability after installation. Attached Figure Description

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0048] Reference Figures 1 to 9 The tunnel evacuation platform composite panel quick-installation support assembly includes a support rod 11 connected to the tunnel sidewall, a guide assembly 2, a limiting assembly 3, and an adjusting assembly 4 mounted on the support rod 11. A clearance groove 111 is provided on the side of the support rod 11 near the tunnel sidewall, and a receiving groove 112 is provided on the side of the support rod 11 away from the tunnel sidewall. During composite panel installation, the guide assembly 2 supports and guides the composite panel's movement. The limiting assembly 3 supports the composite panel and restricts its direction of movement. The adjusting assembly 4 controls whether the limiting assembly 3 is in an extended or retracted state. After the composite panel is moved to the installation position, the limiting assembly 3 switches from the extended state to the retracted state, allowing the composite panel to rest on the support rod 11 and limiting its position.

[0049] Reference Figure 1 and Figure 2As shown, a fixing plate 12 is fixedly installed on the support rod 11 near the tunnel sidewall, and several expansion bolts are provided on the fixing plate 12. The fixing plate 12 is fixed to the tunnel sidewall by the expansion bolts. The support rod 11 is horizontally positioned and extends away from the tunnel sidewall. The surface height of the portion of the support rod 11 that is in the sliding path of the guide assembly 2, i.e., the relief groove 111, is lower than the surface height of the portion of the support rod 11 that is not in the relief groove 111. The depth of the relief groove 111 is configured such that the upper surface of the support plate 211 is flush with the upper surface of the portion of the support rod 11 that is not in the relief groove.

[0050] In this embodiment, two sets of guide components 2, limiting components 3, and adjusting components 4 are provided on the same support rod 11. The composite plate is installed on two adjacent support rods 11, that is, one composite plate is used in conjunction with two sets of guide components 2, limiting components 3, and adjusting components 4 that are close to each other on the two support rods 11.

[0051] Reference Figures 2 to 4 The guide assembly 2 includes a guide member 21 and a guide post 22. The guide member 21 is slidably disposed within the relief groove 111. The guide member 21 includes a support plate 211, two limiting side plates 212, and a connecting shaft 213. The two limiting side plates 212 are respectively fixedly installed on both sides of the support plate 211 perpendicular to its direction of movement. The limiting side plates 212 extend downward. An installation groove 114 is provided at the center of the upper surface of the support rod 11 along its extension direction. The installation groove 114 divides the support rod 11 within the relief groove 111 into two independent sliding parts. The two limiting side plates 212 respectively abut against the sidewalls of the sliding parts, thereby restricting the sliding direction of the support plate 211. A sliding groove 113 is provided on the sidewall of the sliding part, and a guide plate 23 adapted to the sliding groove 113 is fixedly disposed on the side of the limiting side plate 212 away from the support plate 211. The guide plate 23 is horizontally disposed and slides within the sliding groove 113. The limiting side plate 212 and guide plate 23 restrict the support plate 211 to move only along the extension direction of the support rod 11. In this embodiment, the upper surface of the support plate 211 coincides with the upper surface of the non-yielding groove 111 portion of the support rod 11.

[0052] A connecting shaft 213 is fixedly disposed between two limiting side plates 212. The connecting shaft 213 is horizontally positioned, and its axial direction is perpendicular to the extension direction of the support rod 11. A guide post 22 is coaxially rotatably disposed on the connecting shaft 213. The guide post 22 contacts the bottom surface of the relief groove 111. In this embodiment, two connecting shafts 213 and two guide posts 22 are provided, and the two connecting shafts 213 are spaced apart along the moving direction of the support plate 211. The support plate 211 moves horizontally and stably by abutting against the bottom of the relief groove 111 with the two guide posts 22.

[0053] A positioning plate 24 is fixedly installed on the upper surface of the support plate 211 on the side near the tunnel sidewall to limit the position of the end of the composite plate on the support plate 211.

[0054] When installing the composite panel, place one end of the composite panel on the support plate 211 near the end of the positioning plate 24, and then apply a pushing force to the composite panel. This causes the composite panel to move the support plate 211 along the extension direction of the support rod 11. The guide post 22 reduces the friction between the support plate 211 and the support rod 11, making it easier for the operator to push the support plate 211. At the same time, guiding the movement direction of the composite panel through the support plate 211 prevents displacement of the composite panel relative to the support plate 211, thus improving the installation accuracy of the composite panel.

[0055] Reference Figures 3 to 6 The limiting assembly 3 includes a drive rod 31, an extension plate 32, a limiting shaft 33, a limiting post 34, and a limiting plate 35. The drive rod 31 is rotatably disposed within the receiving groove 112, and its axis is parallel to the axis of the connecting shaft 213. The extension plate 32 is fixedly disposed on the drive rod 31 and can rotate synchronously with it, extending radially along the drive rod 31. The limiting shaft 33 is fixedly disposed on the extension plate 32 at the end away from the drive rod 31, and its axial direction is parallel to the axial direction of the drive rod 31. The limiting post 34 is coaxially rotatably disposed on the limiting shaft 33. The limiting plate 35 is fixedly disposed on the side of the extension plate 32 opposite to the limiting shaft 33, and a preset angle is set between the limiting plate 35 and the extension plate 32. When the drive rod 31 rotates, the extension plate 32 drives the limiting shaft 33, the limiting post 34, and the limiting plate 35 to rotate synchronously. The limiting component 3 has two states: extended state and retracted state.

[0056] Reference Figure 7 and Figure 8 In the extended state: the extension plate 32 and the limiting post 34 are located outside the receiving groove 112, used to support the bottom of the composite plate, and cooperate with the support plate 211 to make the composite plate tilted. The composite plate is located on the side of the extension plate 32 away from the tunnel sidewall.

[0057] Reference Figure 9 In its stored state: the extension plate 32 and the limiting post 34 are stored in the receiving groove 112, and the limiting plate 35 is flipped to a position close to the side of the composite plate. This limits the position of the composite plate.

[0058] In this embodiment, when the limiting component 3 is in the extended state, the extension plate 32 is inclined and biased towards one side of the tunnel sidewall. The angle between the extension plate 32 and the limiting plate 35 is set such that when the limiting post 34 retracts into the receiving groove 112, the limiting plate 35 abuts against the sidewall of the composite plate.

[0059] When installing the composite panel, the limiting component 3 is in the extended state. First, place one end of the composite panel on the support plate 211 and adjust its position. Then, place the bottom of the composite panel on the limiting post 34. At this time, the composite panel is tilted, and the operator can easily push the composite panel away from the support plate 211 to move the support plate 211. Continue until the support plate 211 reaches its limit position. Adjust the limiting component 3 to the retracted state, that is, retract the limiting post 34 into the receiving groove 112. At this time, the end of the composite panel near the limiting post 34 descends synchronously until it lands on the support rod 11. The upper surface of the support plate 211 coincides with the upper surface of the non-yielding groove 111 part of the support rod 11 to ensure the horizontal installation of the composite panel. The limiting plate 35 and the positioning plate 24 restrict the movement of the composite panel along the extension direction of the support rod 11.

[0060] Reference Figures 3 to 7 The adjusting assembly 4 includes an adjusting block 41, a limiting block 42, and a baffle 43. One end of the drive rod 31 extends through the support rod 11 and beyond it. The adjusting block 41 is annular and coaxially fixed to the end of the drive rod 31 located outside the support rod 11. The limiting block 42 is fixedly mounted on the adjusting block 41 and extends radially along the adjusting block 41. A limiting groove 421 is formed on the limiting block 42 along its extending direction.

[0061] The baffle 43 is slidably positioned on the side of the support rod 11 corresponding to the adjusting block 41. The baffle 43 slides along the extending direction of the support rod 11. When the baffle 43 is inserted into the limiting groove 421, the position of the drive rod 31 relative to the support rod 11 is restricted. When the baffle 43 is removed from the limiting groove 421, the drive rod 31 can rotate relative to the support rod 11.

[0062] Two limiting blocks 42 are provided, and the two limiting blocks 42 are distributed at intervals along the circumference of the adjusting block 41. Each limiting block 42 has a limiting groove 421, which corresponds to the extended state and the retracted state of the limiting component 3, respectively. When the limiting component 3 is in the extended state, one limiting groove 421 corresponds to the baffle 43; when the limiting component 3 is in the retracted state, the other limiting groove 421 corresponds to the baffle 43, so as to restrict the position of the limiting component 3.

[0063] A second sliding groove is provided on the side of the support rod 11, extending along the extension direction of the support rod 11. A second positioning plate 44, adapted to the sliding groove, is fixedly provided on the side of the baffle 43 near the support rod 11. The second positioning plate 44 slides within the second sliding groove and is used to limit the sliding direction of the baffle 43.

[0064] In this embodiment, two limiting blocks 42 are provided on the adjusting block 41, and each limiting block 42 has a limiting groove 421. The two limiting blocks 42 are distributed at intervals along the circumference of the adjusting block 41. The angle between the two limiting grooves 421 is adapted to the angle between the extension plate 32 and the limiting plate 35. That is, when the limiting component 3 is in the extended state, the baffle 43 corresponds to one limiting groove 421, that is, the baffle 43 is inserted into the limiting groove 421, restricting the rotation of the drive rod 31. When the limiting component 3 is in the retracted state, the baffle 43 corresponds to the other limiting groove 421. By inserting the baffle 43 into the limiting groove 421, the rotation of the drive rod 31 is restricted. This further enhances the limiting effect of the limiting plate 35 on the composite plate and prevents the limiting plate 35 from deflecting under force.

[0065] Reference Figure 3 and Figure 7 To improve the stability of the baffle 43, a support platform 51 is fixedly installed on the support rod 11 on the lower side of the baffle 43. A support plate 52 is provided on the side of the baffle 43 away from the support rod 11. The support plate 52 extends toward the support platform 51 and abuts against the support platform 51. This is to share the force on the baffle 43 and improve the stability of the baffle 43.

[0066] Reference Figure 5 A mounting hole 351 is provided on the limiting plate 35. When it is necessary to disassemble the composite panel, a lever is inserted into the mounting hole 351, which drives the limiting plate 35 to rotate. This, in turn, drives the extension plate 32 and the limiting post 34 to rotate, thereby lifting the composite panel. This facilitates the disassembly of the composite panel by the operator.

[0067] The specific working method is as follows:

[0068] Before installing the composite panel, the guide 21 is moved to the end of the clearance groove 111 away from the tunnel sidewall, and the limiting component 3 is kept in the extended state by the adjusting component 4. At this time, the limiting post 34 extends out of the receiving groove 112. The operator places one end of the composite panel on the support plate 211, and makes the bottom of the composite panel contact the limiting post 34, so that the composite panel is in an inclined state. Then, the composite panel is pushed to move along the extension direction of the support rod 11. The composite panel drives the support plate 211 to move synchronously in the clearance groove 111. During the movement, the guide post 22 rolls in contact with the bottom of the support rod 11 to reduce the movement resistance of the composite panel. When the support plate 211 moves to the predetermined position, the control baffle 43 exits the corresponding limiting groove 421, releasing the rotation restriction on the drive rod 31. Under the action of gravity of the composite panel, the extension plate 32 and the limiting post 34 are driven to rotate, so that they switch from the extended state to the retracted state. The composite panel then descends and falls horizontally onto the support rod 11. Simultaneously, the limiting plate 35 rotates synchronously with the extension plate 32 to the end face of the composite plate and abuts against the end face of the composite plate to restrict the movement of the composite plate along the extension direction of the support rod 11. After the limiting assembly 3 rotates to the retracted state, the baffle 43 is inserted into the corresponding other limiting groove 421 to restrict the position of the drive rod 31, thereby completing the installation of the composite plate.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
