Description
Technical Field
[0001] This utility model relates to the field of arc gate arm welding technology, and in particular to a device for assisting in the positioning and welding of arc gate arms. Background Technology
[0002] In water conservancy projects, the arc-shaped gate is an important hydraulic structure, and the installation and welding of its support arms are crucial to ensuring the overall performance of the arc-shaped gate. However, during the installation process of the arc-shaped gate, there are many technical challenges in the welding and positioning of the support arms, which directly affect the stability and sealing performance of the arc-shaped gate.
[0003] Traditional methods for positioning the outriggers primarily rely on manual measurement and adjustments using lifting equipment. Due to the complex geometry and large spatial span of the curved gate outriggers, precise positioning in three-dimensional space is extremely challenging. Specifically, traditional methods suffer from the following problems:
[0004] Insufficient positioning accuracy: The complex shape of the support arm of the arc gate and the high requirements for its installation position make it difficult to adjust the position of the support arm in real time using traditional methods. This results in insufficient alignment accuracy between the support arm and the gate leaf or other components during welding. This deviation directly affects the quality of the welded joint, and consequently, the overall performance of the arc gate.
[0005] Low construction efficiency: Manual measurement and adjustment require a lot of time and manpower, especially in large-scale projects with long construction cycles, where efficiency issues are particularly prominent.
[0006] High risk of welding deformation: Inaccurate positioning can lead to uneven stress distribution during welding, resulting in welding deformation or stress concentration. These problems not only reduce welding quality but may also shorten the service life of the arc gate.
[0007] Unable to meet the needs of modern engineering: As the requirements for the installation accuracy of arc gates in modern water conservancy projects continue to increase, traditional temporary positioning measures are no longer sufficient to meet the needs of high-precision installation, and a new type of auxiliary positioning device is urgently needed to solve the above problems. Utility Model Content
[0008] To address the aforementioned problems, this utility model provides a simple and easy-to-operate auxiliary arc gate support arm positioning and welding device, which can effectively overcome the limitations of traditional methods and provide reliable technical support for the installation and welding of arc gate support arms.
[0009] The technical solution adopted in this utility model is as follows:
[0010] A device for assisting in the positioning and welding of an arc-shaped gate arm is disclosed. The device has an overall frame structure, including a base frame and sleepers for mounting the top side of the base frame. The base frame is constructed by welding several I-beams and steel bars, and a mounting seat is formed on the top side of the base frame to accommodate the sleepers. The sleepers are rectangular strip structures that are placed at an angle, and their top plane can support the bottom of the arc-shaped gate arm.
[0011] Furthermore, the basic frame includes four columns, each of which is an I-beam of equal height, with reinforcing bars welded into the grooves of the I-beams; the columns are connected laterally by two transverse fixing bars welded to the reinforcing bars of the columns; and the columns are connected longitudinally by two longitudinal fixing bars welded to the transverse fixing bars.
[0012] Furthermore, the basic frame also includes reinforcing bars welded between the columns.
[0013] Furthermore, positioning steel bars are welded to the outside of the basic frame, and the positioning steel bars are welded and fixed to the pre-embedded iron parts embedded in the ground.
[0014] Furthermore, the mounting base includes an I-beam, with reinforcing bars welded into the groove of the I-beam. The I-beam is fixed to the upper part of the end face of the two columns by welding the reinforcing bars. Vertical supporting bars are welded to the outer side of the I-beam of the mounting base relative to the columns. The top surface of the I-beam of the mounting base is provided with a slot for positioning the edge of the sleeper. Adjusting bars are also welded to the two columns of the foundation frame near the mounting base.
[0015] The beneficial effects of this utility model are:
[0016] Improved positioning accuracy: This auxiliary arc gate arm positioning and welding device, through the design of its basic frame, mounting base, sleepers, and positioning steel bars, enables high-precision positioning of the arc gate arm. In particular, the inclined placement of the sleepers, combined with the slot design on the mounting base, ensures the stability of the arm's position and the accuracy of its angle during welding, effectively avoiding the positional deviation problems caused by manual adjustment in traditional methods.
[0017] Improving construction efficiency: This auxiliary arc gate support arm positioning and welding device has an overall frame structure, which is simple to manufacture and install, and easy to operate. By fixing the positioning steel bars to the pre-embedded iron parts in the ground, the time spent on manual measurement and repeated adjustments is reduced, significantly improving construction efficiency. It is especially suitable for the installation of arc gates in large-scale water conservancy projects.
[0018] Reduce welding deformation and stress concentration: Precise positioning and stable support frame design can effectively reduce the problem of uneven stress distribution caused by inaccurate positioning during welding, thereby reducing the risk of welding deformation and stress concentration, improving the quality of welded joints, and extending the service life of the arc gate.
[0019] Enhancing structural stability: The foundation frame is constructed from welded I-beams and reinforcing bars, with the columns reinforced by transverse, longitudinal, and supporting reinforcing bars, forming a rigid and highly stable overall frame. This design not only ensures the stability of the device itself but also provides reliable support for the arc-shaped gate arm.
[0020] Adaptable to complex boom installation requirements: The rectangular strip structure and inclined placement design of the sleepers can flexibly adapt to the complex geometry and spatial span requirements of curved gate booms. Meanwhile, the slots and adjusting steel bars on the mounting base further enhance the device's adaptability to booms of different specifications, meeting diverse engineering needs.
[0021] Reduced manual labor intensity: The device achieves precise positioning of the outrigger through mechanical structure, reducing reliance on manual measurement and adjustment, thus reducing the labor intensity of construction workers and also reducing the possibility of human error.
[0022] In summary, the auxiliary arc gate support arm positioning and welding device provided by this utility model not only solves the problems of insufficient positioning accuracy, low construction efficiency, and high risk of welding deformation in traditional methods, but also has the advantages of simple structure, convenient operation, strong stability, and wide adaptability. It provides reliable technical support for the installation and welding of arc gate support arms and has important engineering application value. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0027] To address the problems of insufficient positioning accuracy, low construction efficiency, and high risk of welding deformation in the traditional installation of arc-shaped gate support arms, this embodiment provides a device to assist in the positioning and welding of arc-shaped gate support arms. For example... Figure 1 As shown, the auxiliary arc-shaped gate support arm positioning and welding device has an overall frame structure, including a base frame 1 and sleepers 2 installed on one side of the top of the base frame 1. The base frame 1 is the core structure of the entire device, providing overall support and stability. The base frame 1 is constructed from several I-beams and reinforcing bars welded together, and its top side forms a mounting base 3 for mounting the sleepers 2. The sleepers 2 are the part that directly contacts the arc-shaped gate support arm; they are rectangular strip structures. The sleepers 2 are placed at an angle, and their top plane provides support to the bottom of the arc-shaped gate support arm.
[0028] Specifically, such as Figure 1 As shown, the basic frame 1 in this embodiment is a frame structure with a width of 700 mm, a length of 1040 mm, and a height of 700 mm. The basic frame 1 includes four columns 4, each of which is an I-beam of equal height. The columns 4 form the vertical support structure of the device, ensuring the overall height and stability of the device. Reinforcing steel bars 5 are welded into the grooves of the I-beams of the columns 4, further improving the bending resistance and load-bearing capacity of the columns 4. Two transverse fixing steel bars 6 are welded to the reinforcing steel bars 5 of the columns 4 laterally. The transverse fixing steel bars 6 connect adjacent columns 4, ensuring the horizontal stability of the basic frame 1, preventing lateral displacement or tilting between the columns 4, and improving the overall rigidity and shear resistance of the frame. Two longitudinal fixing steel bars 7 are welded to the transverse fixing steel bars 6 between the columns 4 longitudinally. The longitudinal fixing steel bars 7 and the transverse fixing steel bars 6 cooperate to form a complete frame structure with the four columns 4, ensuring a firm longitudinal connection between the columns 4, preventing the frame from twisting or deforming, and improving the overall stability of the device in three-dimensional space.
[0029] Furthermore, as a preferred technical solution in this embodiment, such as Figure 1As shown, the basic frame 1 in this embodiment also includes supporting steel bars 8 welded between the columns 4. The supporting steel bars 8 are welded between the columns 4 to enhance the local stability of the frame. The supporting steel bars 8 form diagonal supports inside the frame, distributing loads and improving bending resistance, while reducing the risk of deformation caused by external loads or vibrations. Furthermore, as... Figure 1 As shown, in this embodiment, a positioning steel bar 9 is also welded to the outside of the basic frame 1. One end of the positioning steel bar 9 is welded to the column 4 of the basic frame 1, as shown. Figure 2 As shown, its other end is welded and fixed to the pre-embedded iron part 10 embedded in the ground; the entire device is firmly fixed to the ground by the positioning steel bar 9 to prevent the device from moving due to external force or vibration, thereby ensuring that the device remains stable during the welding process and avoiding the impact of device displacement on the positioning accuracy of the arc gate support arm.
[0030] like Figure 1 As shown, the mounting base 3 in this embodiment includes an I-beam. Reinforcing steel bars 5 are welded into the groove of the I-beam. The I-beam is fixed to the upper end face of the two columns 4 by welding the reinforcing steel bars 5. Vertical supporting steel bars 11 are welded to the outer side of the I-beam of the mounting base 3 relative to the columns 4. The bottom of the vertical supporting steel bars 11 contacts the ground. These bars enhance the local stability of the mounting base 3, prevent bending or deformation of the mounting base 3 due to excessive load on the arc-shaped gate arm, improve the load-bearing capacity of the mounting base 3, and ensure the reliability of the support for the sleepers 2 and the arc-shaped gate arm.
[0031] The top surface of the I-beam of the mounting base 3 is provided with a slot for positioning the edge of the sleeper 2. The slot is not shown in the figure. The two columns 4 of the foundation frame 1 near the mounting base 3 are also welded with adjusting steel bars 12. When the sleeper 2 is subjected to the pressure load of the arc gate support arm, the adjusting steel bars 12 and the slots position the sleeper 2 to prevent the sleeper 2 from sliding or shifting during use. At the same time, the adjusting steel bars 12 limit the inclined surface at the bottom of the sleeper 2 to ensure the docking accuracy of the arc gate support arm with other components.
[0032] Based on the specific structure of the aforementioned auxiliary arc-shaped gate support arm positioning and welding device, its usage method is as follows:
[0033] like Figure 2As shown, before hoisting the support arm 13, the installation of the hinge and gate leaf 14 must be completed to ensure their accurate positioning. This is the basis for the subsequent precise positioning of the support arm 13. Then, using hoisting equipment, the support arm 13 of the arc gate is hoisted to the installation position; one end of the support arm 13 is connected to the pre-installed hinge, ensuring a firm connection; the other end of the support arm 13 is placed on the auxiliary arc gate support arm positioning and welding device, using the sleepers 2 on the device to support the bottom of the support arm 13. Then, the position of the support arm 13 is adjusted to ensure that the docking accuracy between the support arm 13 and the gate leaf 14 meets the design requirements; during the adjustment process, measuring tools such as laser rangefinders or levels can be used to further confirm the spatial position of the support arm 13. Finally, after the positional accuracy of the support arm 13 and the gate leaf 14 is adjusted, the gate can be... Figure 2 Welding is performed at position A, where the support arm 13 contacts the door leaf 14.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
