Description

Technical Field

[0001] This utility model relates to the field of tunnel support technology, specifically to an arch frame installation platform for water conveyance tunnels. Background Technology

[0002] Support structures are crucial safety features in engineering construction. They are primarily used to support and stabilize underground or surface structures, ensuring smooth construction and structural integrity. These devices typically consist of robust support materials and precise fixing systems, and come in various forms, such as sheet piles, continuous walls, and cast-in-place piles, to adapt to different geological conditions and construction requirements. They effectively prevent soil and rock displacement and collapse, while also serving as water stoppers and retaining walls. In projects such as deep foundation pits, underground tunnels, and mines, the role of support structures is particularly critical. They not only concern the safety of construction workers but also directly affect the overall stability and service life of the structure. Therefore, when selecting and applying support structures, it is essential to fully consider geological conditions, construction conditions, and structural requirements to ensure they possess sufficient strength and stability to guarantee the safety and quality of the project.

[0003] During the construction of the transport tunnel, an arch frame installation platform is usually required to support the installation of the arch frame. However, since the position of the upper components of the supporting arch frame is relatively fixed, it is not convenient to adjust the position of the clamping plate. Utility Model Content

[0004] To address the technical problem that existing arch support installation platforms for water conveyance tunnels are inconvenient for adjusting the position of the curved arch plates, this utility model provides an arch support installation platform for water conveyance tunnels that can adjust the position of the abutment plates longitudinally, laterally, and vertically within the tunnel. This facilitates position adjustment of the abutment plates, thereby improving the support efficiency of the water conveyance tunnel and further ensuring construction safety.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides an arch frame installation platform for a water conveyance tunnel, comprising: a support base with a slide rail at its upper end; multiple lifting support columns, each with its lower end slidably connected to a corresponding slide rail, and each lifting support column capable of extension and retraction; an arc-shaped support plate installed on the upper end of the lifting support columns, with at least one lifting support column located at each corner of the arc-shaped support plate; a longitudinal drive mechanism connected to the lower end of the lifting support columns for driving the lifting support columns to move longitudinally along the corresponding slide rail; multiple abutment plates for supporting the tunnel's top wall; and a lateral adjustment mechanism installed on the top of the arc-shaped support plate for adjusting the position of the abutment plates circumferentially on the arc-shaped support plate.

[0007] The water conveyance tunnel arch frame installation platform provided by this utility model includes a support base, a lifting support column, an arc-shaped support plate, a longitudinal drive mechanism, a clamping plate, and a lateral adjustment mechanism. A slide rail is provided at the upper end of the support base, and the lower end of the lifting support column is slidably connected to the corresponding slide rail. The longitudinal drive mechanism is driven to move the lifting support column longitudinally along the corresponding slide rail, thereby adjusting the longitudinal position of the lifting support column in the tunnel. Simultaneously, the lifting support column is telescopic. The arc-shaped support plate is installed at the upper end of the lifting support column to adjust the arc-shaped support plate through the telescopic movement of the lifting support column. Vertically within the tunnel, and at least at each corner of the curved support plate, lifting support columns are installed to ensure the stability of the curved support plate during lifting and operation. Furthermore, the abutment plate is installed on top of the curved support plate via a lateral adjustment mechanism, allowing adjustment of its position circumferentially. Thus, through the cooperation of the longitudinal drive mechanism, the lateral adjustment mechanism, and the lifting support columns, this invention enables longitudinal, lateral, and vertical position adjustment of the abutment plate within the tunnel, facilitating position adjustment and improving the support efficiency of the water conveyance tunnel, further ensuring construction safety.

[0008] In an optional embodiment of this application, two slide rails are arranged in parallel to ensure that each corner of the arc-shaped support plate is supported by a lifting support column.

[0009] In an optional embodiment of this application, the lifting support column is an electric push rod, so as to control the lifting and lowering of the lifting support column.

[0010] In an optional embodiment of this application, a slider is provided at the lower end of the lifting support column, and the slider is slidably connected to the slide rail; the longitudinal drive mechanism includes: a drive screw, which is arranged parallel to the corresponding slide rail, the drive screw is screwed to the corresponding slider, and the drive screw is rotatably connected to the corresponding slide rail; a drive motor, the output end of which is provided with a drive wheel; and a driven wheel, which is fixedly connected to the corresponding drive screw, and each driven wheel is connected to the drive transmission to ensure that the longitudinal drive mechanism can lift and lower the support column and move it longitudinally along the corresponding slide rail.

[0011] In an optional embodiment of this application, both the drive wheel and the driven wheel are synchronous wheels or sprockets to ensure that the two drive screws can move synchronously, thereby avoiding jamming during the movement of the lifting support column.

[0012] In an optional embodiment of this application, the longitudinal drive mechanism further includes a threaded sleeve, which is sleeved on the corresponding drive screw and fixedly connected to the corresponding slider, so as to screw the drive screw and the slider together.

[0013] In an optional embodiment of this application, limit blocks are provided on both sides of the slider along its length, and multiple balls are adapted to the upper and lower sides of each limit block; the slide rail is a grooved slide rail, and limit grooves are provided on both inner sidewalls of the slide rail. The limit grooves are adapted to the limit blocks, and the limit blocks are inserted into the corresponding limit grooves. Thus, the setting of the limit blocks and limit grooves facilitates efficient limiting of the slider, thereby improving the stability of the slider's movement. The ball bearings effectively reduce the frictional force when the limit blocks and limit grooves slide relative to each other.

[0014] In an optional embodiment of this application, the lateral adjustment mechanism includes: an arc-shaped guide rod fixed to the arc-shaped support plate and extending circumferentially along the arc-shaped support plate; a rotating platform mounted on the arc-shaped guide rod, the position of the rotating platform along the length of the arc-shaped guide rod being variable; and a support platform connected to the rotating platform. The abutment plate is fixedly mounted on the support platform to ensure that the lateral adjustment mechanism can adjust the position of the abutment plate circumferentially on the arc-shaped support plate. The support platform provides good support for the abutment plate and facilitates replacement of the abutment plate to accommodate different specifications of abutment plates.

[0015] In an optional embodiment of this application, the rotating platform is bolted to the arc-shaped guide rod to facilitate adjustment of the position of the rotating platform on the arc-shaped guide rod.

[0016] In an optional embodiment of this application, the side of the abutment plate away from the support platform is fitted with an anti-slip pad, which facilitates the abutment plate to fit against the tunnel top and avoids slippage, thereby improving the safety of use.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] The water conveyance tunnel arch frame installation platform provided by this utility model includes a support base, a lifting support column, an arc-shaped support plate, a longitudinal drive mechanism, a clamping plate, and a lateral adjustment mechanism. A slide rail is provided at the upper end of the support base, and the lower end of the lifting support column is slidably connected to the corresponding slide rail. The longitudinal drive mechanism is driven to move the lifting support column longitudinally along the corresponding slide rail, thereby adjusting the longitudinal position of the lifting support column in the tunnel. Simultaneously, the lifting support column is telescopic. The arc-shaped support plate is installed at the upper end of the lifting support column to adjust the arc-shaped support plate through the telescopic movement of the lifting support column. Vertically within the tunnel, and at least at each corner of the curved support plate, lifting support columns are installed to ensure the stability of the curved support plate during lifting and operation. Furthermore, the abutment plate is installed on top of the curved support plate via a lateral adjustment mechanism, allowing adjustment of its position circumferentially. Thus, through the cooperation of the longitudinal drive mechanism, the lateral adjustment mechanism, and the lifting support columns, this invention enables longitudinal, lateral, and vertical position adjustment of the abutment plate within the tunnel, facilitating position adjustment and improving the support efficiency of the water conveyance tunnel, further ensuring construction safety.

[0034] Example

[0035] Combination Figure 1 This embodiment provides a water conveyance tunnel arch frame installation platform, including: a support base 1, with a slide rail 2 provided on the upper end of the support base 1; multiple lifting support columns 5, the lower ends of the lifting support columns 5 being slidably connected to the corresponding slide rail 2, and each of the lifting support columns 5 being extendable and retractable; an arc-shaped support plate 6, the arc-shaped support plate 6 being installed on the upper end of the lifting support columns 5, and at least each corner of the arc-shaped support plate 6 being provided with a lifting support column 5; a longitudinal drive mechanism 8, the longitudinal drive mechanism 8 being drively connected to the lower end of the lifting support column 5, for driving the lifting support column 5 to move longitudinally along the corresponding slide rail 2; abutment plates 7, multiple abutment plates 7 being provided, for supporting the top wall of the tunnel; and a lateral adjustment mechanism 9, the lateral adjustment mechanism 9 being installed on the top of the arc-shaped support plate 6, capable of adjusting the position of the abutment plates 7 in the circumferential direction of the arc-shaped support plate 6.

[0036] It is understandable that two slide rails 2 are arranged in parallel to ensure that each corner of the arc-shaped support plate 6 is supported by a lifting support column 5.

[0037] The lifting support column 5 can be a hydraulic rod, a threaded jack, etc. In this embodiment, the lifting support column 5 is an electric push rod, so as to control the lifting and lowering of the lifting support column 5.

[0038] Combination Figure 2 and Figure 3 The lower end of the lifting support column 5 is provided with a slider 4, which is slidably connected to the slide rail 2. The longitudinal drive mechanism 8 includes: a drive screw 85, which is arranged parallel to the corresponding slide rail 2, screwed to the corresponding slider 4, and rotatably connected to the corresponding slide rail 2; a drive motor 81, the output end of which is provided with a drive wheel; and a driven wheel, which is fixedly connected to the corresponding drive screw 85, and each driven wheel is connected to the drive transmission to ensure that the longitudinal drive mechanism 8 can lift and lower the support column 5 and move it longitudinally along the corresponding slide rail 2.

[0039] It should be understood that there are two driven wheels, and both the drive wheel and the driven wheel are either synchronous wheels or sprockets to ensure that the two drive screws 85 can move synchronously, thereby avoiding jamming during the movement of the lifting support column 5. In this embodiment, both the driven wheel and the drive wheel are synchronous wheels, namely the first synchronous wheel 82 and the second synchronous wheel 84, and the first synchronous wheel 82 and the second synchronous wheel 84 are connected by a synchronous belt 83.

[0040] It is known that the longitudinal drive mechanism 8 also includes a screw sleeve 86, which is sleeved on the corresponding drive screw 85 and is fixedly connected to the corresponding slider 4 so as to screw the drive screw 85 and the slider 4 together.

[0041] Based on this, limit blocks 87 are provided on both sides of the slider 4 along its length, and multiple balls 89 are adapted to the upper and lower sides of each limit block 87; the slide rail 2 is a grooved slide rail 2, and limit grooves 88 are provided on both inner sidewalls of the slide rail 2. The limit grooves 88 are adapted to the limit blocks 87, and the limit blocks 87 are inserted into the corresponding limit grooves 88. Thus, the setting of the limit blocks 87 and the limit grooves 88 facilitates efficient limiting of the slider 4, thereby making the movement of the slider 4 more stable, while the setting of the balls 89 effectively reduces the friction when the limit blocks 87 and the limit grooves 88 slide relative to each other.

[0042] Combination Figure 5 The lateral adjustment mechanism 9 includes: an arc-shaped guide rod 92, which is fixed on the arc-shaped support plate 6 and extends circumferentially along the arc-shaped support plate 6; a rotating platform 93, which is mounted on the arc-shaped guide rod 92 and whose position along the length of the arc-shaped guide rod 92 is variable; and a support platform 94, which is connected to the rotating platform 93. The clamping plate 7 is fixedly mounted on the support platform 94 to ensure that the lateral adjustment mechanism 9 can adjust the position of the clamping plate 7 circumferentially on the arc-shaped support plate 6. The support platform 94 provides good support for the clamping plate 7 and facilitates replacement of the clamping plate 7 to accommodate clamping plates of different specifications.

[0043] Specifically, the rotating platform 93 is bolted to the arc-shaped guide rod 92 to facilitate adjustment of its position on the rod. Rotation is achieved through a damped sliding connection to the arc-shaped guide rod 92 and secured with bolts. Simultaneously, the support platform 94 is bolted to the rotating platform 93. Furthermore, the arc-shaped guide rod 92 is fixed to the arc-shaped support plate 6 via vertical plates 91 mounted on both sides of the top of the support plate 6.

[0044] In an optional embodiment of this application, the side of the abutment plate 7 away from the support platform 94 is fitted with an anti-slip pad 95, such as a soft pad made of rubber, to facilitate the abutment plate 7 to fit against the top of the tunnel, while avoiding slippage and improving the safety of use.

[0045] In summary, the water conveyance tunnel arch frame installation platform provided in this embodiment includes a support base 1, lifting support columns 5, arc-shaped support plates 6, a longitudinal drive mechanism 8, a clamping plate 7, and a lateral adjustment mechanism 9. The support base 1 has a slide rail 2 at its upper end, and the lower end of the lifting support column 5 is slidably connected to the corresponding slide rail 2. The longitudinal drive mechanism 8 is drively connected to the lower end of the lifting support column 5, driving the lifting support column 5 to move longitudinally along the corresponding slide rail 2, thereby adjusting the longitudinal position of the lifting support column 5 in the tunnel. Simultaneously, all lifting support columns 5 are telescopic. The arc-shaped support plate 6 is installed at the upper end of the lifting support column 5, allowing adjustment of the vertical position of the arc-shaped support plate in the tunnel through the telescopic movement of the lifting support column 5. At least each corner of the arc-shaped support plate 6 is equipped with a lifting support column 5, ensuring the stability of the arc-shaped support plate 6 during lifting and operation. Furthermore, the clamping plate 7 is installed on top of the arc-shaped support plate 6 through the lateral adjustment mechanism 9, allowing adjustment of the circumferential position of the clamping plate 7 on the arc-shaped support plate 6.

[0046] Specifically, in use, the rotation of the drive motor 81 drives the first synchronous pulley 82 to rotate, which in turn drives the synchronous belt 83 to rotate. The synchronous belt 83 drives the second synchronous pulley 84 to rotate, which in turn drives the two drive screws 85 to rotate, causing the corresponding screw sleeves 86 to move. The screw sleeves 86 then drive the corresponding slider 4 to move laterally along the limit block 87 and the limit groove 88, thereby driving the top lifting support column 5 to move longitudinally along the corresponding slide rail 2. At the same time, the lifting support column 5 drives the top arc-shaped support plate 6 to rise and fall.

[0047] Simultaneously, by adjusting the position of the rotating platform 93 on the arc-shaped guide rod 92, the tunnel inner wall at different angles can be firmly fixed. Furthermore, by adjusting the position of the rotating platform 93 with bolts, the position of the clamping plate 7 on the circumferential direction of the arc-shaped support plate 6 can be adjusted via the lateral adjustment mechanism 9. After further adjustment, the arc-shaped support plate 6 is finally moved towards the top of the tunnel by the lifting support column 5, causing the clamping plate 7 to firmly press against the tunnel inner wall, thus providing efficient support.

[0048] In summary, the water conveyance tunnel arch frame installation platform provided in this embodiment, through the cooperation of the longitudinal drive mechanism 8, the lateral adjustment mechanism 9 and the lifting support column 5, can adjust the position of the abutment plate 7 in the tunnel in the longitudinal, lateral and vertical directions, so as to improve the support efficiency of the water conveyance tunnel and further ensure construction safety.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
