Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, and in particular to a butterfly-shaped ditch construction device. Background Technology

[0002] In the construction of highway subgrades and various infrastructure projects, butterfly-shaped side ditches are important drainage structures. Their construction quality and efficiency directly affect the overall drainage performance and service life of the project. At present, the industry mostly adopts the slipform construction technology for the construction of butterfly-shaped side ditches. This technology relies on the slipform machine to drive the slipform template to continuously form materials such as concrete. It has advantages such as high construction efficiency and stable forming quality, and has become the mainstream technical means for the construction of butterfly-shaped side ditches.

[0003] Existing sliding membrane machines and sliding membrane templates are generally designed as a single unit, forming an inseparable whole structure. However, due to the different inclination angles of butterfly-shaped ditches in different engineering scenarios, and the fixed inclination angle of the sliding membrane template in integrated sliding membrane equipment, which cannot be adjusted according to construction needs, construction units must purchase a separate set of sliding membrane machines for each inclination angle if they need to construct butterfly-shaped ditches with different inclination specifications. This not only requires repeated investment of a large amount of money to purchase the main body of the sliding membrane machine, but also incurs the transportation and storage costs of multiple machines. Therefore, we have launched a new butterfly-shaped ditches construction device. Utility Model Content

[0004] The main objective of this invention is to provide a butterfly-shaped ditch construction device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A butterfly-shaped ditch construction device includes a sliding membrane machine body and a sliding membrane template. The lower left and lower right ends of the sliding membrane machine body are fixedly connected to connecting ear plates. The upper front and upper rear ends of the two connecting ear plates are provided with through mounting holes. A butterfly bolt is installed in each of the four mounting holes. Two T-shaped positioning grooves are provided at the lower ends of the two connecting ear plates. Threaded holes are provided at the four corners of the upper end of the sliding membrane template. Two T-shaped positioning strips are fixedly connected to the upper left and upper right ends of the sliding membrane template.

[0006] Preferably, the two connecting ear plates are symmetrically distributed on both sides of the synovial machine body.

[0007] By adopting the above technical solution, it can be ensured that the connecting ear plates on both sides of the main body of the sliding film machine are subjected to balanced forces, so that the forces on both sides are symmetrical after the sliding film template is installed.

[0008] Preferably, the four mounting holes correspond to the positions of the four threaded holes.

[0009] By adopting the above technical solution, it can be ensured that the wing bolts can accurately pass through the mounting holes and mate with the corresponding threaded holes, providing an installation benchmark for the fixed connection between the sliding template and the main body of the sliding machine, and avoiding problems such as installation difficulties or unstable connections caused by hole position deviations.

[0010] Preferably, the four wing bolts are threadedly connected to the four threaded holes respectively.

[0011] By adopting the above technical solution, the stability of the threaded connection can be used to reliably fix the sliding formwork to the bottom of the sliding formwork machine body. At the same time, the wing bolts can be manually tightened or disassembled without special tools, which facilitates the quick completion of the installation and replacement of the sliding formwork and improves the convenience of construction.

[0012] Preferably, all four T-shaped positioning slots are open at the front and closed at the rear.

[0013] By adopting the above technical solution, the T-shaped positioning strip can be easily pushed into the groove from the front to achieve initial installation. At the same time, the rear closed structure can axially limit the T-shaped positioning strip, ensuring that the positioning strip is fixed in position after it is fully inserted, avoiding excessive pushing or displacement of the positioning strip during installation, and providing a guarantee for subsequent hole alignment.

[0014] Preferably, the four T-shaped positioning strips are respectively engaged and connected to the four T-shaped positioning slots.

[0015] By adopting the above technical solution, the relative displacement of the sliding template in the horizontal and vertical directions can be restricted by the interlocking action of the T-shaped structure, so as to achieve rapid positioning of the sliding template and the connecting ear plate, ensure that the mounting hole and the threaded hole are automatically aligned, and enhance the initial stability of the connection between the two, providing a reliable foundation for subsequent bolt fixing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By using four T-shaped positioning strips on the sliding template to cooperate with four T-shaped positioning grooves on the ear plate of the main body of the sliding template machine, which are open at the front and closed at the rear, the four threaded holes can be quickly aligned with the four mounting holes after the T-shaped positioning strips are fully inserted into the T-shaped positioning grooves. At the same time, the T-shaped positioning groove structure, which is open at the front and closed at the rear, can also form a preliminary limit after the T-shaped positioning strips are inserted, so as to prevent the sliding template from shifting during the subsequent installation of the wing bolts. 2. When the four threaded holes correspond to the four mounting holes, the four wing bolts can be passed through the mounting holes in sequence and screwed into the corresponding threaded holes, so that the sliding formwork can be installed under the main body of the sliding formwork machine. It is also convenient to replace the sliding formwork with different tilt angles. By designing the sliding formwork as a detachable structure, it is not necessary to prepare multiple specifications of sliding formwork machines for the construction needs of ditches with different tilt angles. Only sliding formwork of different specifications needs to be prepared, which reduces equipment procurement costs and inventory management costs. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: A butterfly-shaped ditch construction device includes a sliding membrane machine body 1 and a sliding membrane template 2. The lower left and lower right ends of the sliding membrane machine body 1 are fixedly connected to connecting ear plates 3. The upper front and upper rear ends of the two connecting ear plates 3 are provided with through mounting holes 4. The four mounting holes 4 are provided with butterfly bolts 5. The lower ends of the two connecting ear plates 3 are provided with two T-shaped positioning grooves 6. The upper four corners of the sliding membrane template 2 are provided with threaded holes 7. The upper left and upper right ends of the sliding membrane template 2 are fixedly connected with two T-shaped positioning strips 8.

[0023] In this embodiment, two connecting ear plates 3 are symmetrically distributed on both sides of the slide film machine body 1, four mounting holes 4 correspond to the positions of four threaded holes 7 respectively, and four wing bolts 5 are threadedly connected to the four threaded holes 7 respectively.

[0024] With the above solution: the two connecting ear plates 3 are symmetrically distributed on both sides of the slipform machine body 1, which can make the force on both sides of the slipform machine body 1 even. The positions of the four mounting holes 4 and the four threaded holes 7 correspond to each other, providing precise guidance for the installation of the wing bolts 5. This avoids the problem that the wing bolts 5 cannot be smoothly inserted or the connection will be loose after installation due to hole position deviation. At the same time, the threaded connection between the four wing bolts 5 and the threaded holes 7 can not only achieve a stable fixation between the slipform template 2 and the slipform machine body 1, preventing the slipform template 2 from falling off or shifting during construction, but also improve the convenience of installation and subsequent replacement of the slipform template 2 and save construction time because the wing bolts 5 can be manually tightened or disassembled without special tools.

[0025] In this embodiment, all four T-shaped positioning slots 6 are open at the front and closed at the rear, and the four T-shaped positioning strips 8 are respectively engaged and connected with the four T-shaped positioning slots 6.

[0026] The above solution allows for the following: the open front design of the four T-shaped positioning slots 6 facilitates the smooth pushing of the T-shaped positioning strips 8 on the sliding template 2 into the slots from the front, reducing the operational difficulty of installing the T-shaped positioning strips 8 and improving the initial assembly efficiency; the closed rear structure of the T-shaped positioning slots 6 can axially limit the T-shaped positioning strips 8 after they are fully pushed in, preventing them from being over-push in and ensuring the stability of their position; at the same time, the engaging connection between the four T-shaped positioning strips 8 and the four T-shaped positioning slots 6 can quickly achieve the initial positioning of the sliding template 2 and the connecting ear plate 3, ensuring that the subsequent mounting holes 4 and threaded holes 7 can be accurately aligned, laying the foundation for the smooth installation of the wing bolts 5.

[0027] It should be noted that this utility model is a butterfly-shaped ditch construction device. During use, the first step is to assemble the sliding formwork template 2 with the main body 1 of the sliding formwork machine. The operator aligns the four T-shaped positioning strips 8 on the upper left and right sides of the sliding formwork template 2 with the four T-shaped positioning grooves 6 at the lower left and right ends of the connecting ear plates 3 of the main body 1 of the sliding formwork machine (because the T-shaped positioning grooves 6 are open at the front and closed at the rear). The operator pushes the T-shaped positioning strips 8 into the T-shaped positioning grooves 6 from the front until the T-shaped positioning strips 8 touch the closed rear end of the T-shaped positioning grooves 6. At this point, the four T-shaped positioning strips 8 and the four T-shaped positioning grooves 6 are completely engaged. Simultaneously, because the two connecting ear plates 3 are symmetrically distributed and the four pre-set mounting holes 4 correspond to the four threaded holes 7 at the four corners of the upper end of the sliding formwork template 2, precise alignment of the mounting holes 4 and the threaded holes 7 can be achieved. Then, the operator installs the four butterfly bolts... 5. Insert the four mounting holes 4 on the two connecting ear plates 3 respectively, and screw the wing bolts 5 into the corresponding threaded holes 7. The wing template 2 is securely installed under the body of the wing machine 1 through the threaded connection. After assembly, the construction stage begins. The body of the wing machine 1 runs, driving the fixed wing template 2 below to move along the construction path of the wing ditch, thus realizing the construction of the wing ditch. When it is necessary to construct wing ditches with different inclination angles, simply unscrew the wing bolts 5 in the opposite direction, remove the T-shaped positioning strip 8 from the front opening of the T-shaped positioning groove 6, replace it with a wing template 2 with the corresponding inclination angle and matching the structure of the T-shaped positioning strip 8 and threaded holes 7, and repeat the above assembly steps to continue construction. There is no need to prepare wing machines of various specifications for the construction needs of ditches with different inclination angles. Only wing templates of different specifications need to be prepared, which reduces equipment procurement costs and inventory management costs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
