[0036] Embodiment:
[0037] As shown in Figure 1-2 The present application discloses a single track turnout beam curved beam assembly and welding precision guarantee tool, which is used for controlling the curved line type and ensuring the product quality of the single track turnout beam curved beam.
[0038] The specific structure of the present application includes:
[0039] A plurality of support assemblies 1 are distributed at intervals, a corresponding number of support assemblies can be rotated according to the length of the actual product, and then a corresponding line type is formed, so as to ensure the curvature of the product;
[0040] A plurality of cross braces 2 are installed between two adjacent support assemblies 1 respectively, and the cross braces 2 are combined to form an arc-shaped tooling surface, the cross braces 2 are used to connect the corresponding support assemblies 1, so as to ensure the stability of the adjacent support assemblies 1, thereby ensuring the stability of the overall structure.
[0041] Further limited to the support assembly 1, wherein the support assembly 1 comprises:
[0042] Two ground platforms 101 are arranged at intervals, and the arrangement is that the ground platforms 101 are arranged at intervals along the length direction of the curved beam and are divided into outer sides and inner sides.
[0043] A support plate 102 is installed on the ground platform 101 one by one.
[0044] Two side stops 103 are installed at both ends of the ground platform 101 on the outer side respectively, and the top of the side stop 103 is at the same horizontal plane. The support assembly 1 is designed to add a support plate 102, and the top surface of the support plate 102 is used as a support surface. The top surface of the support plate 102 is a precisely processed plane, and the corresponding flatness needs to be ensured, so as to ensure the precision of the final processing of the product. Meanwhile, the side stop 103 is also provided, which is used for installing components such as jacks in the subsequent process and plays a supporting role, so as to ensure the precision of the product.
[0045] Specifically, the top of the support plate 102 of the support assembly 1 is at the same horizontal plane, so as to ensure the support precision.
[0046] In an embodiment, as shown in Figure 2 The side stop 103 comprises:
[0047] A bottom plate 104 is installed on the ground platform 101, and the bottom plate 104 is used as a support and can be fixedly connected with the ground platform 101 directly.
[0048] A first support plate 105 is installed vertically on the bottom plate 104.
[0049] A second support plate 106 is installed obliquely on the bottom plate 104, and the second support plate 106 is on the outer side, so as to better ensure the stability of the side stop 103.
[0050] A plurality of connecting plates 107 are arranged at intervals from top to bottom between the first support plate 105 and the second support plate 106, and an assembly cavity 108 is formed between any two connecting plates 107. The assembly cavity 108 in the application is convenient for the connection of the cross brace 2 in the subsequent process, and also ensures the stability of the structure.
[0051] The present application utilizes upper and lower adjacent connecting plates 107 to form an assembly cavity 108 to match the cross brace 2 , thereby preventing the cross brace 102 from deflecting, thereby ensuring stability.
[0052] Among them, four cross braces 2 are arranged between two adjacent support components 1, and the cross braces 2 are grouped in pairs. The two groups of cross braces 2 are respectively located at both ends of the support component 1, that is, there are two upper and lower cross braces 2 on one side of the two support components 1, which facilitates the subsequent formation of an arc-shaped processing surface to ensure accuracy.
[0053] The two ends of the cross brace 2 are arranged inside the assembly cavity 108 , so that the cross brace 2 can be more stable during installation.
[0054] Further explanation for this application:
[0055] The installation process of this application can be carried out in the following steps.
[0056] ①First, connect the floor platform to the ground through anchor bolts;
[0057] ② Spot weld the support plate on the ground platform. Before spot welding, the support plate should be erected first and its height should be measured to make sure that the height error of each support plate does not exceed 0.5mm before spot welding. After spot welding, measure the support plate height again and complete the welding after confirming that it does not exceed the error.
[0058] ③ According to the linear layout of the single track switch beam and curved beam, the position of the side guard is set out in advance. The corresponding position is found on site according to the layout position and spot welded first. After secondary calibration, the welding is completed;
[0059] ④ The cross brace is connected to the side guard and is located on the same height partition as the side guard. If an error occurs during the welding process, the top pressure device can be placed on the cross brace at the error position to adjust the turnout beam.
[0060] Among them, the ground platform adopts a combined base, which has high rigidity and is not easy to deform; bolt holes need to be reserved to connect and fix the ground platform to the ground through anchor bolts.
[0061] The steel plates required for the side guards are laser-cut, straightened, and welded after cutting. The side guard partitions' tolerances must be within 1mm during welding. The side guards are spaced apart on both sides of the turnout beam. After spot welding on the ground platform, the height of each side guard partition is measured to ensure that the height tolerance of the partitions in the same position does not exceed 1mm. Welding is performed only after the tolerances are met.
[0062] Among them, the cross brace connects the side guard. As for the position of the partition at the same height, the cross brace adopts [20 channel steel which is not easy to deform and has a large bearing capacity;
[0063] The support plate is made of 16-20mm thick steel plate, which is cut and straightened, and the flatness of the support plate is controlled within 1mm and the perpendicularity is controlled within 0.5mm. The support plate is spot-welded to the ground platform, and the height error of the support plate is ensured to be less than 0.5mm after measurement, and then the support plate can be put into use.
[0064] In use, the following steps are installed:
[0065] S1: group welding of the jig frame, arranging longitudinal and transverse reference lines and detecting the jig frame (i.e. the present application);
[0066] S2: on the special jig frame, the segment assembly is carried out by using the "inverted mounting method", and the longitudinal and transverse reference lines of the jig frame are used as the reference to position the top plate unit, the partition plate, the web plate and the bottom plate, and the box type welding is completed;
[0067] S3: after the box type welding is completed, the geometric size of the track beam is detected, the distance between the beam segment and the side stop is measured, and the distance between the same side and the side stop should be consistent, if the error occurs, the pressing device is placed on the transverse support of the error position to adjust the turnout beam;
[0068] S4: the distance between the top plate and the support plate can directly show the flatness of the whole beam segment, and the flame correction is carried out according to the deformation condition;
[0069] S5: after the detection is qualified, the trolley and the bearing seat are assembled, and after the assembly welding is completed, the secondary detection is carried out again by using the above method;
[0070] S6: after the detection is qualified, the body is turned over and the tire is removed and handed over to the painting workshop.
