Description

Technical Field

[0001] This utility model relates to the field of underground urban auxiliary maintenance, specifically a movable combination template for underground integrated pipe corridors. Background Technology

[0002] Underground utility tunnels, also known as integrated utility tunnels, are underground urban pipeline corridors that integrate various engineering pipelines such as electricity, communications, gas, heating, and water supply and drainage into a single tunnel space built underground in a city. Mobile modular formwork is an auxiliary device used in underground integrated utility tunnels, designed for smooth movement within the tunnel.

[0003] For example, in the patent document with application number 201721432879.2, a mobile modular formwork for underground integrated pipe gallery is disclosed. The mobile modular formwork adopts a combination of retractable mobile support and wheels to facilitate the movement and fixing of the mobile modular formwork during construction.

[0004] In the above technical solution, the pipe gallery has spaces of different sizes. When the movable template moves in different spaces, the size of its external support is difficult to accommodate. It is necessary to replace the movable template with a different size to achieve fixation and support in different spaces. At the same time, in the above technical solution, when the support plate is away from the support frame, the support plate contacts the side wall of the pipe gallery, and its stability cannot be maintained. Therefore, the stability of the movable template cannot be guaranteed. Utility Model Content

[0005] The technical problem solved by this utility model is to address the issue that the stability of the movable template cannot be guaranteed when adjusting its horizontal width in the prior art.

[0006] This utility model can be achieved through the following technical solution: a movable combined formwork for an underground integrated pipe gallery, including a formwork support frame, a number of sets of bottom rollers rotatably arranged at the bottom of the formwork support frame, damping rotating bases slidably arranged on both sides of the formwork support frame, a fixed push plate rotatably arranged on the damping rotating base, and the distance between adjacent damping rotating bases is adjustable.

[0007] A further technical improvement of this utility model is that: the damping rotation base is fixedly installed on the sliding rod, the template support frame is provided with an adjustment cavity, the sliding rod and the template support frame are slidably connected, and an arc-shaped mating plate is fixed at the end of the sliding rod, and the distance between the arc-shaped mating plates is adjustable.

[0008] A further technical improvement of this utility model is that an adjusting spring is fixed between the arc-shaped mating plate and the template support frame, and a downward pressure support rod is threaded on the template support frame. A downward pressure plate and an adjusting plate are fixed at both ends of the downward pressure support rod, and the adjusting plate and the arc-shaped mating plate are mated together.

[0009] A further technical improvement of this utility model is that a support base is fixed to the top of the template support frame, and a top handle is rotatably provided on the support base.

[0010] A further technical improvement of this utility model is that a top telescopic rod is fixed on the top handle, a support base is fixed at the output end of the top telescopic rod, and a support grid for placing tools is fixed on the support base.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This application utilizes a sliding connection between the damping rotating base and the template support frame to control the distance between adjacent damping rotating bases, thereby adjusting the distance between the fixed push plates. This facilitates the contact of the fixed push plates with the side wall of the pipe gallery, thus limiting the position of the template support frame. Furthermore, this application utilizes a rotating connection between the damping rotating base and the fixed push plates, allowing for further adjustment of the distance between the fixed push plates by rotating them 90 degrees. Adjusting the rotation angle of the fixed push plates ensures that the movement distance of the damping rotating base is stable and short, thus guaranteeing the stability of the damping rotating base during lateral movement and further ensuring the stability of the moving template.

[0013] 2. This application provides a support base at the top of the template support and a top handle that is rotatably mounted on the support base. This allows the height of the top to be controlled by rotating the top handle, further ensuring that the movable template can be used in pipe gallery spaces of various heights and facilitating the movement of the movable template. Additionally, a support grid for placing tools is provided on the top handle, ensuring the functionality of the movable template. Attached Figure Description

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Please see Figure 1-3 As shown, a movable combined formwork for an underground integrated utility tunnel includes a utility tunnel 1 and a movable formwork 2, wherein the movable formwork 2 slides inside the utility tunnel 1, and in this application, the utility tunnel 1 has several movable spaces of different sizes. In this application, the movable formwork 2 can be stably moved and fixed within movable spaces of different sizes.

[0021] In this application, the movable template 2 includes a template support frame 8, wherein four sets of template bottom rollers 9 are rotatably provided at the bottom of the template support frame 8, the template bottom rollers 9 are used to realize the movement of the template support frame 8, and a top handle 3 is provided at the top of the template support frame 8 to realize the movement of the template support frame 8 inside the pipe gallery 1.

[0022] Furthermore, fixed push plates 6 are symmetrically arranged on both sides of the template support frame 8 for contacting the inner wall of the pipe gallery 1. The fixed push plates 6 move in opposite directions or backwards under different forces. When the fixed push plates 6 are in the backward movement state, one of the fixed push plates 6 contacts the inner wall of the pipe gallery 1. Then the fixed push plates 6 continue to be in the backward movement state, so that the position of the template support frame 8 inside the pipe gallery 1 is adjusted laterally, so that both sets of fixed push plates 6 contact the inner wall of the pipe gallery 1, realizing the function of fixing the template support frame 8, thereby facilitating the maintenance of the inside of the pipe gallery 1.

[0023] The fixed push plate 6 is rotatably mounted on the damping rotating base 5, so the angle of the fixed push plate 6 can be controlled. At the same time, the damping rotating base 5 is fixedly mounted on the end of the sliding rod 11. An adjustment cavity 7 is provided on the template support frame 8, in which the adjustment cavity 7 and the sliding rod 11 are slidably connected. An arc-shaped mating plate 10 is fixed to the end of the sliding rod 11 away from the damping rotating base 5. The lateral position of the arc-shaped mating plate 10 is adjustable. An adjustment spring 12 is fixed to the side of the arc-shaped mating plate 10 near the damping rotating base 5, and the other end of the adjustment spring 12 is fixedly mounted on the template support frame 8. In use, by adjusting the distance of the arc-shaped mating plate 10, it is convenient to adjust the movement of the sliding rod 11 inside the adjustment cavity 7, thereby facilitating the adjustment of the distance between the damping rotating bases 5 and the distance between the fixed push plates 6.

[0024] To adjust the position of the arc-shaped mating plate 10, a downward pressure support rod 14 is threaded onto the template support frame 8. An adjustment plate 13 is fixed to the end of the downward pressure support rod 14, and a downward pressure plate 15 is fixedly installed at the end of the downward pressure support rod 14 away from the adjustment plate 13. At the same time, the adjustment plate 13 acts between the two sets of arc-shaped mating plates 10. In use, the rotation of the downward pressure plate 15 controls the rotation of the downward pressure support rod 14, thereby controlling the longitudinal height of the downward pressure support rod 14 and the longitudinal height of the adjustment plate 13. This allows the adjustment plate 13 to act on the arc-shaped mating plate 10, controlling the distance of the arc-shaped mating plate 10, and thus controlling the distance of the fixed push plate 6.

[0025] As a further embodiment of this application, the lateral dimension and longitudinal height of the movable template 2 need to be matched with the dimensions of the pipe gallery 1. Therefore, in this application, a support base 4 is fixedly installed on the top of the template support frame 8, and a top handle 3 is rotatably provided on the support base 4. When the longitudinal height of the pipe gallery 1 is low, the top handle 3 can be controlled so that the top handle 3 can rotate under the action of the support base 4, thereby adjusting the height of the top handle 3 to adapt to pipe galleries of various sizes.

[0026] Meanwhile, during use, a top telescopic rod 16 is fixedly installed on the top handle 3, and a support base 17 is fixedly installed on the output end of the top telescopic rod 16. The support base 17 is slidably connected to the top handle 3. At the same time, several sets of support grids 18 for supporting tools are evenly installed on the support base 17. Therefore, when the top handle 3 is rotated during use, the height of the top handle 3 is reduced, and the position of the support grids 18 is adjusted under the action of the top telescopic rod 16, so that tools can be placed on the support grids 18, ensuring the functionality of the pipe gallery 1 during maintenance.

[0027] In use, this utility model first determines the usage form of the movable template 2 based on the dimensions of the pipe gallery 1. When the height of the pipe gallery 1 is high, the top handle 3 is in a high position. Then, when it is necessary to fix the movable template 2, the rotation of the lower pressure plate 15 is used to control the rotation of the lower pressure support rod 14, thereby controlling the longitudinal height of the lower pressure support rod 14 and the longitudinal height of the adjusting plate 13. This allows the adjusting plate 13 to act on the arc-shaped mating plate 10, controlling the distance of the arc-shaped mating plate 10, thereby controlling the distance of the fixed push plate 6. When the fixed push plate 6 is in the back-moving state, one of the fixed push plates 6 contacts the inner wall of the pipe gallery 1. Then, the fixed push plate 6 continues to be in the back-moving state, causing the template support frame 8 to be laterally adjusted inside the pipe gallery 1. This allows both sets of fixed push plates 6 to contact the inner wall of the pipe gallery 1, achieving the function of fixing the template support frame 8, thus facilitating the maintenance of the inside of the pipe gallery 1.

[0028] When it is necessary to further control the distance between the fixed push plates 6, the fixed push plates 6 can be adjusted to ninety degrees, thereby further controlling the distance between the fixed push plates 6. The damping rotating base 5 and the fixed push plates 6 are fixed only by damping force to prevent them from rotating when moving. However, when an external force is applied, the fixed push plates 6 can be made to rotate.

[0029] When it is necessary to control the height of the movable template 2, the top handle 3 is rotated on the support base 4 to make the top handle 3 rotate to a horizontal state. At the same time, the position of the support grid 18 is adjusted under the action of the top telescopic rod 16, so that tools can be placed on the support grid 18 to ensure the functionality of the pipe gallery 1 during maintenance.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
