Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel construction technology, specifically to a tilting secondary lining template trolley grouting device. Background Technology
[0002] In the construction of tunnel secondary lining, there are currently two grouting methods used for tunnel secondary lining formwork trolleys: one is the insert plate type, and the other is the cover plate type.
[0003] Currently, the most common type of grouting port used on tunnel lining formwork trolleys is the cover-plate type. This involves installing a rotatable cover plate on the outside of the trolley panel at the grouting port. When pouring concrete, the cover plate is rotated open. After pouring, the cover plate is rotated again using a handle to seal the grouting port. After lining using this method, a groove will appear at the rotating cover plate on the tunnel ceiling. Another method is the insert-plate type grouting port sealing. This involves installing a pull-out cover plate inside the trolley panel at the grouting port. When pouring concrete, the insert plate is pulled out. After pouring, the insert plate is extended using a telescopic device to seal the grouting port. After lining using this method, a protrusion will appear at the insert plate on the tunnel ceiling, requiring a more cumbersome later aesthetic finishing process. Utility Model Content
[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model to solve its technical problems is: a flip-type secondary lining template trolley grouting device, comprising: a trolley top panel, an outer frame symmetrically and fixedly connected to the outer wall of the trolley top panel, a hinge pin fixedly connected to the outer wall of the outer frame, a support telescopic device rotatably connected to the inner wall of the hinge pin, a flipping component provided at the bottom end of the trolley top panel, and a grouting feed pipe fixedly connected to the bottom end of the flipping component.
[0005] Preferably, the flipping assembly includes a fan-shaped grouting cavity. A cavity hinge pin is rotatably connected to the inner wall of the fan-shaped grouting cavity. A fan-shaped sealing rotating block is slidably connected to the inner wall of the fan-shaped grouting cavity. A connecting lug is fixedly connected to the outer wall of the fan-shaped sealing rotating block. A grouting pipe is fixedly connected to the outer wall of the fan-shaped grouting cavity. The fan-shaped sealing rotating block rotates via the cavity hinge pin, causing grouting material to be injected through the grouting feed pipe. The grouting feed pipe delivers the grouting material to the grouting pipe fixedly connected to it. The grouting pipe is connected to the fan-shaped grouting cavity. After entering the fan-shaped grouting cavity, the grouting material diffuses in all directions under pressure, evenly filling the areas requiring grouting.
[0006] Preferably, the outer wall of the top end of the fan-shaped grouting cavity is fixedly connected to the outer wall of the top panel of the trolley, the outer wall of the fan-shaped sealing rotating block is fixedly connected to the inner wall of the cavity hinge pin, and the end of the grouting pipe away from the fan-shaped grouting cavity is fixedly connected to the outer wall of the grouting feed pipe.
[0007] Preferably, the support telescopic device includes a rotating cylinder, the inner wall of which is symmetrically threaded with a support rod, and the end of the support rod away from the rotating cylinder is fixedly connected to a connecting block.
[0008] Preferably, the outer wall of one of the connecting blocks is rotatably connected to the inner wall of the hinge pin, and the outer wall of the other connecting block is rotatably connected to the inner wall of the connecting lug. By rotating the rotating cylinder to adjust the extension length of the support rod, the connecting lug is pulled or pushed, which in turn drives the fan-shaped sealing rotating block to rotate through the cavity hinge pin, thereby completing the opening and closing operation.
[0009] The beneficial effects of this utility model are as follows:
[0010] 1. This utility model, through the setting of a device and the adoption of a fan-shaped grouting cavity structure, enables the grouting material to diffuse evenly in all directions under pressure during grouting, ensuring uniform distribution of the grouting material in the areas to be filled, effectively improving the grouting quality and making the tunnel lining structure more stable. In the sealing operation after grouting, the fan-shaped sealing rotating block rotates through the cavity hinge pin and slides in the fan-shaped grouting cavity to achieve sealing, and its plane contacts the top panel of the trolley, avoiding the problem of grooves or protrusions after sealing like traditional cover plate or insert plate grouting ports, thereby improving the quality of the secondary lining construction at the top of the tunnel and reducing the need for subsequent tunnel top beautification procedures.
[0011] 2. This utility model optimizes the structure of the trolley, significantly reducing the volume occupied by the trolley in the tunnel clearance. While the trolley is performing secondary tunnel lining construction, other tunnel construction processes can be carried out simultaneously without interference. This greatly improves tunnel construction efficiency, shortens the construction period, and uses a rotating cylinder with a support telescopic device to adjust the extension length of the support rod, thereby controlling the movement of the tilting component. The operation is simple and easy to understand, requiring no complex tools or techniques, thus reducing the operational requirements for construction personnel. Attached Figure Description

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0019] Example:
[0020] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a flip-type secondary lining template trolley grouting device, comprising: a trolley top panel 1, an outer frame 2 symmetrically fixedly connected to the outer wall of the trolley top panel 1, a hinge pin 5 fixedly connected to the outer wall of the outer frame 2, a support telescopic device 6 rotatably connected to the inner wall of the hinge pin 5, a flipping component 4 provided at the bottom end of the trolley top panel 1, and a grouting feed pipe 3 fixedly connected to the bottom end of the flipping component 4.
[0021] The flipping assembly 4 includes a fan-shaped grouting cavity 41. A cavity hinge pin 42 is rotatably connected to the inner wall of the fan-shaped grouting cavity 41. A fan-shaped sealing rotating block 43 is slidably connected to the inner wall of the fan-shaped grouting cavity 41. A connecting lug 44 is fixedly connected to the outer wall of the fan-shaped sealing rotating block 43. A grouting pipe 45 is fixedly connected to the outer wall of the fan-shaped grouting cavity 41. The fan-shaped sealing rotating block 43 rotates via the fixedly connected cavity hinge pin 42. Grouting material is injected through the grouting feed pipe 3, which transports the grouting material to the fixedly connected grouting pipe 45. The grouting pipe 45 is connected to the fan-shaped grouting cavity 41. After entering the fan-shaped grouting cavity 41, the grouting material diffuses in all directions under pressure, evenly filling the areas requiring grouting.
[0022] The top outer wall of the fan-shaped grouting cavity 41 is fixedly connected to the outer wall of the top panel 1 of the trolley, the outer wall of the fan-shaped sealing rotating block 43 is fixedly connected to the inner wall of the cavity hinge pin 42, and the end of the grouting pipe 45 away from the fan-shaped grouting cavity 41 is fixedly connected to the outer wall of the grouting feed pipe 3.
[0023] The support telescopic device 6 includes a rotating cylinder 61, with a support rod 62 symmetrically threaded to the inner wall of the rotating cylinder 61, and a connecting block 63 fixedly connected to the end of the support rod 62 away from the rotating cylinder 61.
[0024] The outer wall of one of the connecting blocks 63 is rotatably connected to the inner wall of the hinge pin 5, and the outer wall of the other connecting block 63 is rotatably connected to the inner wall of the connecting lug 44.
[0025] Working principle:
[0026] In use, the entire device is installed on a tunnel secondary lining formwork trolley. The top panel 1 of the trolley serves as the basic component, and the outer frame 2, symmetrically fixed to its outer wall, provides support and connection points for subsequent components. The support telescopic device 6 is rotatably connected to the outer frame 2 via a hinge pin 5, and its other end is rotatably connected to the connecting lug 44 of the tilting assembly 4 via a connecting block 63. At this time, the extension length of the support rod 62 can be adjusted by rotating the rotating cylinder 61, thereby adjusting the initial position and angle of the tilting assembly 4 to place it in a suitable grouting-ready state.
[0027] When grouting is required, the support telescopic device 6 is operated to move the support rod 62 inward, pulling the connecting lug 44, which in turn drives the fan-shaped sealing rotating block 43 to rotate through the cavity hinge pin 42. This allows the grouting material to be injected through the grouting feed pipe 3. The grouting feed pipe 3 delivers the grouting material to the grouting pipe 45, which is fixedly connected to it. The grouting pipe 45 is connected to the fan-shaped grouting cavity 41. After the grouting material enters the fan-shaped grouting cavity 41, it diffuses in all directions under pressure, evenly filling the area requiring grouting. After grouting is completed, the grouting port needs to be sealed. Then, by operating the support telescopic device 6, the support rod 62 extends outward, pushes the connecting ear seat 44, and drives the fan-shaped sealing rotating block 43 to rotate through the cavity hinge pin 42. The fan-shaped sealing rotating block 43 slides in the fan-shaped grouting cavity 41, gradually sealing the grouting port to prevent the grouting material from flowing back and to ensure the tightness of the seal. The contact between the plane of the fan-shaped sealing rotating block 43 and the top panel 1 of the trolley prevents grooves or protrusions from appearing at the rotating cover plate of the concrete outline at the top of the tunnel.
[0028] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
