Description

Technical Field

[0001] This utility model relates to the field of tunnel construction escape passage technology, specifically to a rapid installation device for escape pipelines and a tunnel escape system. Background Technology

[0002] During tunnel construction, in the event of a collapse or other safety accident, escape routes are typically constructed within the tunnel to protect the lives of construction workers. These escape routes consist of multiple steel escape pipes connected sequentially. Due to the considerable length of tunnels, and the typical length of a single escape pipe being 3 meters, existing technology uses clamps to fix the ends of adjacent escape pipes to ensure they can be connected and form an escape route. While clamps can connect the escape pipes, the following problems exist in actual installation and use: 1. The escape pipes are cylindrical. When connecting two escape pipes using clamps, the ends of the two pipes need to be aligned. However, the tunnel surface may be uneven, and the escape pipes are heavy, requiring considerable time for hoisting and adjusting their position. This not only increases installation costs but also reduces installation efficiency; 2. Using clamps, the multiple escape pipes connected sequentially form a cylindrical shape. Under external forces within the tunnel, these pipes are prone to rolling and bending, causing the clamp connection to fail and rendering the entire escape route ineffective. Utility Model Content

[0003] The present invention aims to provide a rapid installation device for escape pipes and a tunnel escape system to solve the problems of low installation efficiency and poor connection stability of escape pipes when using clamps to install escape pipes in the prior art.

[0004] To solve the above problems, the present invention adopts the following technical solution: a quick installation device for escape pipes, comprising several installation mechanisms connected in sequence, with adjacent installation mechanisms being detachably connected; two end supports are provided in the installation mechanism facing each other, a bottom support is connected between the two end supports, and side blocking members are fixedly connected to both sides of the bottom support; the bottom support, the side blocking members, and the two end supports form an installation groove with an open top for installing the escape pipe, and the end supports are provided with escape holes that cooperate with the escape pipe.

[0005] The principles and beneficial effects of this application are as follows:

[0006] In this application, each installation mechanism is equipped with an end support, a bottom support, and a side blocking component. The end support, bottom support, and side blocking component form an installation groove with an open top. The escape pipe in the prior art can be placed into the installation groove from the top opening downwards. The bottom support provides vertical support for the installed escape pipe, and the side blocking component limits the escape pipe from both sides, enabling the escape pipe to be installed quickly and accurately in the installation groove. At the same time, one or multiple escape pipes can be installed in each installation groove, simply by setting the length of the installation groove to an integer multiple of the length of the escape pipe, further improving the installation efficiency of the escape pipe.

[0007] Compared to the existing technology that uses clamps to fix escape pipes, the technical solution of this application only requires the escape pipe to be hoisted and placed in the installation groove. The installation groove can automatically limit and fix the escape pipe, resulting in higher installation efficiency. Moreover, multiple escape pipes can be installed at the same installation groove, further improving the efficiency of escape pipe installation. On the other hand, the installation groove formed by the installation mechanism in this application limits and fixes the escape pipe. Even if an accident such as a collapse occurs during construction, the bottom, sides, and both ends of the escape pipe are stably supported and limited, which can effectively reduce the lateral displacement or swaying of the escape pipe, making the escape pipe stably form an escape channel, and making it safer and more stable to use.

[0008] Meanwhile, among the multiple installation mechanisms provided in this application, adjacent installation mechanisms are detachably connected. Therefore, when actually installing the escape tunnel, one or more escape tunnels can be installed into the installation slot first, and then the installation mechanism together with the installed escape tunnel can be hoisted to the predetermined position. The end supports at both ends serve as the lifting positions, so that the entire installation mechanism and escape tunnel can be hoisted stably. Then, the adjacent installation mechanisms are connected, so that the escape tunnels in the two adjacent installation slots can be connected as one. This not only makes the escape tunnel installed quickly and efficiently, but also ensures that when the installation is completed, all installation mechanisms are connected as one, resulting in higher overall structural stability. In the event of an accident such as a collapse, it can form an escape tunnel more stably, providing more stable protection for construction personnel.

[0009] Preferably, as an improvement, the end support includes a column and a crossbeam. There are two columns, both of which are vertically arranged. The bottom end of the column is fixedly connected to the bottom support, and the crossbeam is fixedly connected between the top ends of the two columns.

[0010] In this design, the end support includes columns and beams. When the two columns and the beam are fixed together, the beam, the two columns, and the bottom support form the escape hole. The structure is simple and very stable. The two columns can also play a lateral limiting and blocking role for the escape pipe, so that the escape pipe is more stably limited and fixed in the installation groove.

[0011] Preferably, as an improvement, an end plate is fixedly connected between the two columns, and the end plate is provided with a through hole, the diameter of which is equal to the inner diameter of the escape pipe.

[0012] An end plate is fixed between two columns. The end plate can limit the escape pipe in the axial direction, preventing it from sliding along its own axis after it is installed in the installation groove. This further improves the stability of the escape pipe after installation. Moreover, when hoisting the installation mechanism and the installed escape pipe, it can prevent the escape pipe from slipping out of the installation groove, thus improving the stability of the escape pipe during the installation process.

[0013] Preferably, as an improvement, the end face of the end plate facing out of the mounting groove is flush with the side of the column facing the adjacent end support, the thickness of the end plate is less than the width of the crossbeam, and the number of escape pipes installed in the mounting groove is greater than or equal to three.

[0014] In this design, the end face of the end plate facing out of the mounting groove is flush with the side of the column facing the adjacent end support. When adjacent mounting mechanisms are connected, the sides of the columns in the adjacent mounting mechanisms are in contact with each other, and the end plates of the two mounting mechanisms are also in a close fit, making the close fit between the adjacent mounting mechanisms more stable.

[0015] More importantly, in this design, the thickness of the end plate is less than the width of the crossbeam. With the end face of the end plate flush with the side of the column, the side of the crossbeam facing the mounting groove protrudes beyond the side of the end plate facing the mounting groove. When the escape pipe is installed in the mounting groove, the end of the escape pipe closest to the column contacts the side of the end plate facing the mounting groove. At this point, the portion of the crossbeam protruding from the side of the end plate provides vertical restraint on the end of the escape pipe, preventing it from moving freely in the vertical direction and ensuring a more stable installation within the mounting groove. Furthermore, this design specifically limits the number of escape pipes installed in the mounting groove to at least three. When installing the escape pipes, first install the escape pipes at both ends of the mounting groove, then install the remaining escape pipes vertically, ensuring that all escape pipes can be installed smoothly.

[0016] Preferably, as an improvement, the clearance hole on the end plate is provided with a locking hole.

[0017] In this design, since the end plate is fixedly connected between two columns, and the end plate has a square panel structure, while the end of the escape pipe is cylindrical, through holes are set on the end plate, and space is left at the four corners of the end plate. Lock holes are set within this range to avoid the through holes. When two adjacent installation mechanisms are connected to each other, the end plates in the two installation mechanisms fit together, and the lock holes on the end plates face each other. At this time, the two end plates are fixed with bolts, which can conveniently and stably connect the two installation mechanisms to each other.

[0018] Preferably, as an improvement, the bottom support includes a bottom support beam and a bottom connecting beam, the number of bottom support beams is two and the two ends of the bottom support beams are respectively connected to two end supports, and the bottom connecting beam is fixedly connected between the bottom support beams.

[0019] Preferably, as an improvement, the side blocking member includes a lateral stop post fixedly connected to the bottom support beam, and the lateral stop post is arranged vertically.

[0020] In this design, the bottom support beam and the bottom connecting beam provide vertical stability support for the escape pipe. The lateral support columns are vertically installed on the bottom support beam, which can limit the sides of the escape pipe, thereby providing stable support and limiting function for the escape pipe.

[0021] Preferably, as an improvement, the side blocking member further includes an inclined side stop bar, the bottom end of which is fixedly connected to the bottom support beam, and the top end of which is fixedly connected to the side stop post.

[0022] In this design, inclined lateral stops are installed on both sides of the escape tunnel, which can better limit and stabilize the escape tunnel. After the lateral stops are installed, the top of the lateral stops is fixed to the lateral stop post, making the connection between the lateral stop post and the bottom support beam more stable.

[0023] Preferably, as an improvement, a lifting ring is fixedly connected to the crossbeam.

[0024] In this design, lifting rings are connected to the crossbeams. After the escape pipe is installed into the installation groove, the installation mechanism and the escape pipe can be easily installed using the lifting rings.

[0025] The tunnel escape system includes the aforementioned rapid installation device for the escape pipe.

[0026] By installing a quick-installation device for escape pipes within the tunnel escape system, escape pipes can be installed conveniently and quickly, effectively improving installation efficiency. Furthermore, once installed, the escape pipes can be connected as a single unit, resulting in a stable structure and a reliable escape route. Attached Figure Description

[0033] The following detailed description illustrates the specific implementation method:

[0034] The reference numerals in the accompanying drawings include: bottom support beam 1, bottom connecting beam 2, column 3, crossbeam 4, side retaining column 5, side retaining bar 6, end plate 7, through hole 701, lock hole 702, bolt 8, nut 9, clamp 10, lifting ring 11, and escape pipe 1000.

[0035] Example 1

[0036] This embodiment is as shown in the appendix. Figure 1 and Figure 3 As shown: The escape tunnel quick-installation device includes several sequentially connected installation mechanisms, which are detachably connected to each other. Specifically, each installation mechanism has two opposing end supports, each with an escape hole that mates with the escape tunnel 1000. A bottom support is connected between the two end supports, and side blocking members are fixedly connected to both sides of the bottom support. The bottom support, side blocking members, and the two end supports form an installation groove with an open top for installing the escape tunnel 1000. One or more escape tunnels 1000 can be installed in the installation groove.

[0037] like Figure 1As shown, the bottom support includes a bottom support beam 1 and a bottom connecting beam 2. There are two bottom support beams 1 arranged parallel to each other. The bottom connecting beam 2 is vertically welded between the two bottom support beams 1, and there are multiple bottom connecting beams 2, which are spaced apart along the length of the bottom support beams 1. The end support includes a column 3 and a crossbeam 4. The column 3 is vertically arranged, and there are two columns 3. The bottom end of the column 3 is welded to the end of the bottom support beam 1, and the two ends of the crossbeam 4 are respectively welded to the top of the two columns 3. The two columns 3 and the crossbeam 4 form the aforementioned escape hole. After the escape pipe 1000 is installed in the installation groove, the end of the escape pipe 1000 is directly opposite the escape hole. The side blocking components include a lateral stop post 5 and a lateral stop bar 6, which are fixedly connected to the bottom support beam 1 by welding. The lateral stop post 5 is set vertically, the bottom end of the lateral stop bar 6 is welded to the bottom support beam 1, and the top end of the lateral stop bar 6 is welded to the top end of the lateral stop post 5. Furthermore, a lateral stop bar 6 is provided on both sides of each lateral stop post 5, making the connection between the lateral stop post 5 and the bottom support beam 1 more stable.

[0038] To improve the stability of the escape pipe 1000 after it is installed in the mounting slot, combined with Figure 1 and Figure 2 In this embodiment, an end plate 7 is welded and fixed between the two columns 3. The end plate 7 has a through hole 701 that mates with the escape pipe 1000, and the diameter of the through hole 701 is equal to the inner diameter of the escape pipe 1000. Simultaneously, the end face of the end plate 7 facing out of the mounting groove is flush with the side of the column 3 facing the adjacent end support. The thickness of the end plate 7 is less than the width of the crossbeam 4, causing the side of the crossbeam 4 facing into the mounting groove to protrude beyond the end face of the end plate 7 facing into the mounting groove. When the escape pipe 1000 is installed into the mounting groove, the end of the escape pipe 1000 closest to the end plate 7 contacts the end plate 7. The portion of the crossbeam 4 protruding into the mounting groove from the end face of the column 3 will limit the vertical upward movement of the escape pipe 1000, preventing it from... During use, the escape pipe 1000 can move upwards freely, effectively ensuring the stability of the escape pipe 1000 after installation. Therefore, in this embodiment, to ensure that the escape pipe 1000 can be smoothly installed into the installation groove from top to bottom, the number of escape pipes 1000 in the same installation groove is greater than or equal to three. First, the escape pipes 1000 at both ends are hoisted into the installation groove, and then the escape pipe 1000 is pushed along the axial direction of the escape pipe 1000 so that the end of the escape pipe 1000 contacts the end plate 7. In addition, in this embodiment, multiple locking holes 702 are opened in the clearance holes 701 on the end plate 7. When adjacent installation mechanisms are connected to each other, the end plates 7 in the adjacent installation mechanisms contact each other. At this time, the bolts 8 in the prior art are passed through the locking holes 702, and then the nuts 9 are used for fixing, so that the two installation mechanisms can be easily connected and fixed.

[0039] In this embodiment, when installing the escape pipe 1000, the escape pipes 1000 are first hoisted into the installation groove from top to bottom. For the escape pipes 1000 near both ends of the installation groove, after lowering them into the groove, they need to be moved laterally to bring their ends into contact with the end plate 7. Then, the remaining escape pipes 1000 are installed, simply by placing them downwards into the installation groove. Figure 3 and Figure 4 After the corresponding number of escape pipes 1000 are installed into the installation slot, the installation mechanism together with the escape pipes 1000 in the installation mechanism is hoisted to the predetermined position. Finally, the end plate 7 in the installation mechanism is connected and fixed to other end plates 7 in the installation mechanism that have been installed using bolts 8.

[0040] The tunnel escape system includes the aforementioned escape pipe installation device. Since installing the escape pipe 1000 is simple—just placing it into the installation groove—installation is convenient and highly efficient. Furthermore, after installation, the bottom, ends, and sides of the escape pipe 1000 are all restrained, ensuring its stable installation within the groove. When connected to escape pipes 1000 in adjacent installation mechanisms, it can stably form an escape passage, providing stable safety protection for construction personnel.

[0041] Example 2

[0042] The difference between Example 2 and Example 1 is as follows: Figure 5 As shown, in this embodiment, clamps 10 are installed at the contacting ends of two adjacent escape pipes 1000 in the same mounting groove. By using the clamps 10 for connection and fixation, all escape pipes 1000 in the mounting groove are connected as one, and the resulting escape channel has better sealing, stability and safety. In this embodiment, the escape pipe 1000 is cylindrical and the mounting groove has a square cross-section. There is an operating space between the outer wall of the cylindrical escape pipe 1000 and the bottom support beam 1, which can facilitate the installation of clamps 10.

[0043] Example 3

[0044] The difference between Example 3 and Example 2 is as follows: Figure 6 As shown, in this embodiment, a lifting ring 11 is welded to the top of the crossbeam 4. After the escape pipe 1000 is installed into the installation groove, the entire installation mechanism together with the escape pipe 1000 can be lifted conveniently and stably by the lifting ring 11, making the installation of the escape pipe 1000 safer and more efficient.
