Description

Technical Field

[0001] This utility model belongs to the field of rail transit technology, specifically relating to a tooling for installing and debugging a rail transit floodproof door. Background Technology

[0002] In rail transit engineering, drop-down floodgates are important civil defense and flood control equipment. Their doors typically consist of an H-shaped steel frame and sealing plates. During the door manufacturing process, a large sealing base plate needs to be precisely installed into the H-shaped steel frame.

[0003] Taking a common type of drop-down floodgate as an example, the dimensions of its sealing base plate on the door leaf are: length 6900mm, width 366mm, and thickness 15mm. According to the installation process requirements, this sealing base plate needs to be lowered by 5mm before being welded to the edge of the H-shaped steel frame. In the existing installation process, no dedicated positioning auxiliary structure is usually set up, and the installation process relies entirely on workers using measuring tools (such as steel rulers and levels) to repeatedly measure, adjust, and position manually.

[0004] This purely manual installation method has the following obvious problems and drawbacks:

[0005] 1. Positioning accuracy is difficult to guarantee. Since the sealing base plate is 6900mm long, it is very difficult to accurately control the overall 5mm sinking requirement without any auxiliary positioning reference, which can easily lead to excessive deviation in the installation position.

[0006] 2. Flatness control is difficult. Long, thin plates (15mm thick) will deflect under their own weight. During welding, welding thermal stress can also cause uneven stress on the plates, resulting in further deformation. Without effective multi-point support, the overall flatness cannot be guaranteed, which will ultimately seriously affect the sealing performance of the floodgate.

[0007] 3. Low work efficiency: During installation, workers need to repeatedly measure and calibrate multiple locations, making the process cumbersome and the installation of a single door time-consuming, resulting in low overall production efficiency and a high dependence on the experience and sense of responsibility of the operators. Utility Model Content

[0008] The present invention aims to solve, at least to some extent, the aforementioned technical problems. Therefore, the purpose of this invention is to provide a tooling for installing and debugging flood-proof doors for rail transit.

[0009] The technical solution adopted in this utility model is as follows:

[0010] A fixture for installing and debugging a floodgate for rail transit, used to install a sealing base plate onto an H-shaped steel frame, includes: at least two positioning base plates spaced apart along the length of the H-shaped steel frame, the positioning base plates being fixed to the flanges of the H-shaped steel frame for bottom support and initial positioning of the sealing base plate; and at least two adjusting components, the adjusting components being disposed on the web of the H-shaped steel frame and used to apply adjusting force to the sealing base plate to precisely adjust the installation height and flatness of the sealing base plate.

[0011] In a preferred embodiment, the positioning base plates are equidistantly distributed along the length of the H-shaped steel frame and symmetrically fixed to the flanges on both sides of the H-shaped steel frame. This symmetrical multi-point support structure can evenly distribute the self-weight of the sealing base plates, effectively preventing them from deflecting due to their own weight, and providing a basis for ensuring flatness.

[0012] In a preferred embodiment, the adjustment components are arranged along the length of the H-beam steel frame, and the position of each adjustment component corresponds to the position of a symmetrically arranged positioning base plate in the length direction. This ensures that on each support section formed by the positioning base plate, there is an adjustment component providing precise height fine-tuning capability.

[0013] In a preferred embodiment, the adjusting assembly includes a nut and a screw. The nut is welded and fixed to the web of the H-beam steel frame; the screw is threaded into the nut, and the top end of the screw abuts against and supports the bottom surface of the sealing base plate. By rotating the screw, small vertical displacement adjustments of the sealing base plate can be easily achieved.

[0014] In a preferred embodiment, the number of positioning base plates is 20, symmetrically arranged on the flanges of both sides of the H-shaped steel frame, 10 on each side. Correspondingly, the number of adjusting components is also 20.

[0015] In a preferred embodiment, the spacing between two adjacent positioning base plates is approximately 345 mm. This spacing design is sufficient to provide adequate support for the sealing base plate, which is up to 6900 mm long.

[0016] In a preferred embodiment, the nut is an M20 hexagonal nut; the screw is an M20 high-strength screw to provide sufficient support and adjustment strength.

[0017] In a preferred embodiment, the positioning base plate is a steel plate with a thickness of 5mm to 8mm and a width of 25mm to 40mm, ensuring sufficient support rigidity.

[0018] In a preferred embodiment, the vertical distance between the top surface of the positioning base plate and the inner plane of the H-beam frame flange is set according to the thickness of the sealing base plate and the required settlement amount, so as to achieve preliminary height positioning of the sealing base plate. For example, when the thickness of the sealing base plate is 15mm and the required settlement amount is 5mm, its bottom surface should be located 20mm below the top surface of the H-beam flange. In this case, the top surface of the positioning base plate can be welded to a position 20mm below the top surface of the H-beam flange to achieve coarse positioning.

[0019] The beneficial effects of this utility model are as follows:

[0020] This invention provides stable and uniform bottom support for the sealing base plate by setting a multi-point positioning base plate on the H-shaped steel frame, effectively controlling its flatness. At the same time, with the help of the screw-type adjustment component, the height of the sealing base plate can be finely adjusted at the millimeter level or even more precisely, thereby accurately achieving the required amount of sinking and ensuring that the final installation accuracy meets the design specifications.

[0021] The tooling structure is simple, and the adjustment method is intuitive. Operators do not need advanced skills or extensive experience to easily complete high-precision installation and debugging work, reducing reliance on manual labor. The number, spacing, and specific parameters of the positioning base plate and adjustment components can be flexibly adjusted according to different sizes and installation requirements of the sealing base plate, making it suitable for mass production of similar flood-proof doors or other similar panel installations.

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings herein can generally be arranged and designed in various different configurations.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, the installation and commissioning fixture for a rail transit floodgate in this embodiment integrates positioning and adjustment functions on the H-shaped steel frame 1 of the floodgate, which is used to install a long sealing base plate 2 into place.

[0030] In this embodiment, a sealing base plate 2 with a length of 6900mm, a width of 366mm, and a thickness of 15mm is used as an example. The installation requirements are that the top surface of the sealing base plate 2 needs to be 5mm lower than the top surface of the flange of the H-shaped steel frame 1, and the overall flatness tolerance requirement is ±0.2mm.

[0031] The tooling mainly includes a positioning base plate 3 and an adjustment assembly 4.

[0032] In this embodiment, 20 Q235 steel plates are used as positioning base plates 3. Each steel plate has dimensions of 8mm thickness and 40mm width. These 20 positioning base plates 3 are symmetrically welded to the inner flanges of both sides of the H-shaped steel frame 1, 10 plates on each side, equidistantly distributed along a length of 6900mm, with a center-to-center distance of approximately 345mm between adjacent positioning base plates 3. The welding method is double-sided full welding, with a weld height of 3mm to ensure a firm connection.

[0033] The installation height of the positioning base plate 3 is crucial. Since the sealing base plate 2 is 15mm thick, its top surface is required to be recessed by 5mm. This means its bottom surface needs to be 20mm (15mm + 5mm) below the top surface of the flange of the H-beam frame 1. Therefore, when welding the positioning base plate 3, the vertical distance between its top surface (i.e., the supporting surface) and the top surface of the flange of the H-beam frame 1 must be precisely controlled at 20mm. In this way, when the sealing base plate 2 is placed on all the positioning base plates 3, its height basically meets the design requirements, achieving rapid initial positioning.

[0034] In this embodiment, 20 adjustment components 4 are provided, each corresponding one-to-one with one of the 20 positioning base plates 3 in the length direction. For example... Figure 2 and Figure 3As shown, each adjusting component 4 consists of a nut 41 and a screw 42. The nut 41 is an M20 hexagonal nut, and the screw 42 is an M20 high-strength screw with a length of 70mm. The nut is firmly welded to the web plate in the middle of the H-beam frame 1, positioned at the center of the cross-section and aligned with the positioning base plates 3 on both sides along its length. The screw 42 is screwed into the nut 41, its axis perpendicular to the web plate of the H-beam frame 1, and its top end is used to press upward against the bottom surface of the sealing base plate 2.

[0035] The installation and debugging process of the tooling described in this utility model is as follows:

[0036] Step 1: Tooling preparation. On the H-beam frame 1, weld 20 positioning base plates 3 and 20 nuts 41 to the side flanges and center web plate respectively according to the predetermined positions. Screw all the screws 42 into the nuts 41, and initially adjust their top height to be slightly lower than the top surface of the positioning base plates 3.

[0037] Step 2: Preliminary Positioning. The sealing base plate 2 is hoisted and placed inside the H-beam steel frame 1, ensuring its bottom rests on the supporting surfaces of the 20 positioning base plates 3. At this point, the lateral position and approximate height of the sealing base plate 2 are determined.

[0038] Step 3: Precision Adjustment. Rotate each of the 20 screws 42 one by one, causing them to move upwards and press against the bottom surface of the sealing base plate 2. Use a precision measuring instrument such as a laser level or dial indicator to perform multi-point measurements on the upper surface of the sealing base plate 2. By fine-tuning the rotation of each screw 42, apply a small lifting force to the sealing base plate 2 to eliminate the deflection caused by the plate's own weight, and precisely adjust the height of each point until the top surface of the entire sealing base plate 2 meets the requirement of sinking 5mm, and the overall flatness error is within ±0.2mm.

[0039] Step 4: Welding and Fixing. After the sealing base plate 2 is precisely fixed in the target position using the positioning base plate 3 and the adjusting assembly 4, welding can be performed. To prevent welding heat deformation from affecting the adjusted precision, preliminary fixing can be done using segmented spot welding. After the overall position is stable, full welding can be performed. Throughout the welding process, this fixture continuously provides stable support, effectively suppressing welding deformation. After welding is completed, the high-precision installation of the sealing base plate is finished.

[0040] Those skilled in the art will understand that the above embodiments are merely preferred examples of this utility model. Various transformations and modifications can be made without departing from the principle of this utility model. For example, the number and spacing of the positioning base plate and adjusting components can be adjusted according to the size and rigidity of the sealing base plate; the adjusting components can also take other forms, such as wedge block adjusting mechanisms or eccentric wheel adjusting mechanisms, as long as they can achieve the vertical fine-tuning function of the sealing base plate; the connection between the positioning base plate and the H-beam can also be a bolted connection for reuse. All these transformations and modifications should fall within the protection scope of this utility model.
