Description

Technical Field

[0001] This invention relates to the technical field of gate installation methods, and more specifically, to a method for installing a large-span gate. Background Technology

[0002] Gates are key structural components in water conservancy projects, used for water retention and storage. They typically consist of gate leaves installed within a gate slot; specifically, the left end of the gate leaf is located on the left side of the slot, and the right end on the right side. Depending on usage requirements, the gate span may need to be increased to create large-span gates. However, this increases the gate's size and weight, and existing lifting equipment has limited load-bearing capacity, making it difficult to lift the entire gate as a whole. To facilitate the lifting and transportation of large-span gates, they can be divided into multiple units along the left-right direction, and these units can be assembled sequentially from the left side of the gate slot to the right side.

[0003] Because of the large span of the gate, when there is a small deviation between the unit body on the left end of the gate and the left side of the gate slot, when this deviation extends to the right end of the gate, it will cause a large deviation between the unit body on the right end of the gate and the right side of the gate slot. This makes it difficult to connect the unit body on the right end of the gate and the right side of the gate slot, increasing the installation difficulty of the gate. Summary of the Invention

[0037] In this embodiment, the first component is first positioned on one side of the door slot, and the installation accuracy of the first component is adjusted using a first adjusting mechanism until the installation accuracy of the first component meets a first preset condition. Then, the first component is connected to one side of the door slot. Next, the second component is positioned in the middle of the door slot, and the installation accuracy of the second component is adjusted using a second adjusting mechanism until the installation accuracy of the second component meets a second preset condition. Then, the second component and the first component are connected.

[0038] In summary, when the first component is installed, the first adjusting mechanism is used to adjust the installation precision of the first component, so as to reduce the installation error between the first component and the gate slot; when the second component is installed, the second adjusting mechanism is used to adjust the installation precision of the second component, so as to reduce the installation error between the second component and the first component; when the third component is installed, the third adjusting mechanism is used to adjust the installation precision of the third component, so as to reduce the installation error between the third component and the second component and the gate slot. In this way, the first adjusting mechanism, the second adjusting mechanism and the third adjusting mechanism are used to respectively adjust the installation precision of the first component, the second component and the third component, so as to reduce the installation error of the first component, the second component and the third component, and ensure that the third component can be accurately installed to the right side of the gate slot, thereby simplifying the installation process of the large-span gate and reducing the installation difficulty of the large-span gate.

[0039] Optionally, the first preset condition comprises that the first component is perpendicular to the installation platform and parallel to the left side of the gate slot.

[0040] The second preset condition comprises that the second component is perpendicular to the installation platform and parallel to the first component.

[0041] The third preset condition comprises that the third component is perpendicular to the installation platform and parallel to the second component and the right side of the gate slot.

[0042] In this embodiment, the first component is installed on the left side of the gate slot, the first adjusting mechanism is used to adjust the inclination of the first component in the front-rear direction and the left-right direction, wherein the inclination in the front-rear direction is adjusted to be perpendicular to the installation platform, and the inclination in the left-right direction is adjusted to be parallel to the left side of the gate slot; the second component is arranged in the middle of the gate slot, the second adjusting mechanism is used to adjust the inclination of the second component in the front-rear direction and the left-right direction, wherein the inclination in the front-rear direction is adjusted to be perpendicular to the installation platform, and the inclination in the left-right direction is adjusted to be parallel to the first component; the third component is arranged on the right side of the gate slot, the third adjusting mechanism is used to adjust the inclination of the third component in the front-rear direction and the left-right direction, wherein the inclination in the front-rear direction is adjusted to be perpendicular to the installation platform, and the inclination in the left-right direction is adjusted to be parallel to the second component and the right side of the gate slot. In this way, the first adjusting mechanism is used to adjust the first component to be perpendicular to the installation platform and parallel to the left side of the gate slot, the second adjusting mechanism is used to adjust the second component to be perpendicular to the installation platform and parallel to the first component, and the third adjusting mechanism is used to adjust the third component to be perpendicular to the installation platform and parallel to the right side of the gate slot, so as to reduce the installation error of the first component, the second component and the third component, and ensure that the third component can be accurately installed to the right side of the gate slot, thereby simplifying the installation process of the large-span gate and reducing the installation difficulty of the large-span gate.

[0043] Optionally, the driving the first adjusting mechanism to adjust the levelness and the inclination of the first assembly, and connecting the first assembly to one side of the gate slot comprises: when the levelness of the first assembly is the same as the levelness of the installation platform, and the inclination of the first assembly is the same as the inclination of the gate slot, setting a first supporting pad between the gap between the first assembly and the installation platform;

[0044] the driving the second adjusting mechanism to adjust the levelness and the inclination of the second assembly, and splicing the second assembly and the first assembly comprises: when the levelness of the second assembly is the same as the levelness of the installation platform, and the inclination of the second assembly is the same as the inclination of the first assembly, setting a second supporting pad between the gap between the second assembly and the installation platform;

[0045] the driving the third adjusting mechanism to adjust the levelness and the inclination of the third assembly, and connecting the third assembly to the other side of the gate slot comprises: when the levelness of the third assembly is the same as the levelness of the installation platform, and the inclination of the third assembly is the same as the inclination of the second assembly, setting a third supporting pad between the gap between the third assembly and the installation platform.

[0046] In the embodiment, when the first adjusting mechanism is used to adjust the parallelism and the inclination of the first assembly, a gap between the first assembly and the installation platform can be caused, and the first supporting pad is set between the gap to support the first assembly; similarly, when the second adjusting mechanism is used to adjust the parallelism and the inclination of the second assembly, a gap between the second assembly and the installation platform can be caused, and the second supporting pad is set between the gap to support the second assembly; in addition, when the third adjusting mechanism is used to adjust the parallelism and the inclination of the third assembly, a gap between the third assembly and the installation platform can be caused, and the third supporting pad is set between the gap to support the third assembly. Thus, the first supporting pad, the second supporting pad and the third supporting pad are respectively set to support the first assembly, the second assembly and the third assembly, which can ensure the stability of the first assembly, the second assembly and the third assembly, and is beneficial to splicing the first assembly, the second assembly and the third assembly, thereby simplifying the installation process of the large-span gate and reducing the installation difficulty of the large-span gate.

[0047] Optionally, as shown in Figure 2 the second assembly comprises a first sub-assembly 21 and a second sub-assembly 22;

[0048] The driving of the second adjusting mechanism adjusts the levelness and the inclination of the second assembly, and the splicing of the second assembly and the first assembly further comprises: arranging the first sub-assembly 21 on the mounting platform, arranging the second adjusting mechanism on the mounting platform, and connecting the second adjusting mechanism and the first sub-assembly 21, driving the second adjusting mechanism to adjust the levelness and the inclination of the first sub-assembly 21, until the levelness of the first sub-assembly 21 is the same as the levelness of the mounting platform, and the inclination of the first sub-assembly 21 is the same as the inclination of the first assembly, and a second supporting pad is arranged between the gap between the first sub-assembly 21 and the mounting platform; and splicing the second sub-assembly 22 with the first sub-assembly 21.

[0049] The second sub-assembly 22 is arranged at the upper end of the first sub-assembly 21. At the same time, the splicing part of the first sub-assembly 21 and the second sub-assembly 22 is spot-welded to strengthen the connection.

[0050] In the embodiment, the second assembly is arranged as the first sub-assembly 21 and the second sub-assembly 22, the first sub-assembly 21 can be hoisted first, until the first sub-assembly 21 is located between the first assembly and the third assembly, and the first sub-assembly 21 is connected with the first assembly and the third assembly; then the second sub-assembly 22 is hoisted, until the second sub-assembly 22 is located at the upper end of the first sub-assembly 21 and between the first assembly and the third assembly, and the lower end of the second sub-assembly 22 is connected with the upper end of the first sub-assembly 21. Thus, since the height of the second assembly is large, it is inconvenient to transport, the second assembly can be divided into the first sub-assembly 21 and the second sub-assembly 22 with smaller height, which is convenient for transportation. At the same time, the first sub-assembly 21 and the second sub-assembly 22 can be hoisted respectively, which reduces the hoisting weight when the second assembly is installed, and facilitates the splicing of the second assembly with the first assembly, thereby simplifying the installation process of the large-span gate and reducing the installation difficulty of the large-span gate.

[0051] Optionally, as shown in Figure 2 The first sub-assembly 21 comprises a plurality of first sub-assembly units, and the plurality of first sub-assembly units are distributed from left to right. The driving of the second adjusting mechanism adjusts the installation precision of the second assembly until the installation precision of the second assembly meets the second preset condition. The splicing of the second assembly and the first assembly further comprises: arranging the first sub-assembly unit on the mounting platform, arranging the second adjusting mechanism on the mounting platform, and connecting the second adjusting mechanism and the first sub-assembly unit, driving the second adjusting mechanism to adjust the installation precision of the first sub-assembly unit until the installation precision of the first sub-assembly unit meets the second preset condition, and arranging a second supporting pad between the gap between the first sub-assembly unit and the mounting platform; repeating the above operation until the plurality of first sub-assembly units all meet the second preset condition; and splicing the plurality of first sub-assembly units.

[0052] The first sub-assembly 21 is divided into several first sub-unit bodies, and the first sub-unit bodies are arranged in the left-to-right direction. The second unit body 211 is arranged on the left side and connected with the first assembly. The third unit body 212 is arranged in the middle of the gate slot and connected with the second unit body 211. The fourth unit body 213 is arranged on the right side of the gate slot and connected with the third unit body 212. Thus, the first sub-assembly 21 is divided into several first sub-unit bodies with moderate width, which facilitates the transportation of the first sub-assembly 21. Meanwhile, the several first sub-unit bodies are hoisted respectively, which reduces the hoisting weight during the installation of the first sub-assembly 21, facilitates the splicing of the first sub-assembly 21 and the first assembly, and thus simplifies the installation process of the large-span gate and reduces the installation difficulty of the large-span gate.

[0053] In the embodiment, the first sub-assembly 21 is divided into several first sub-unit bodies, and the first sub-unit bodies are arranged in the left-to-right direction. The second unit body 211 is arranged on the left side and connected with the first assembly. The third unit body 212 is arranged in the middle of the gate slot and connected with the second unit body 211. The fourth unit body 213 is arranged on the right side of the gate slot and connected with the third unit body 212. Thus, the first sub-assembly 21 is divided into several first sub-unit bodies with moderate width, which facilitates the transportation of the first sub-assembly 21. Meanwhile, the several first sub-unit bodies are hoisted respectively, which reduces the hoisting weight during the installation of the first sub-assembly 21, facilitates the splicing of the first sub-assembly 21 and the first assembly, and thus simplifies the installation process of the large-span gate and reduces the installation difficulty of the large-span gate.

[0054] Optionally, as shown in FIG. 6, the second sub-assembly 22 includes several second sub-unit bodies. The splicing of the second sub-assembly 22 and the first sub-assembly 21 includes: first, splicing the several second sub-unit bodies into the second sub-assembly 22, and then splicing the second sub-assembly 22 and the first sub-assembly 21.

[0055] The second sub-assembly 22 includes several second sub-unit bodies, and the splicing of the second sub-assembly 22 and the first sub-assembly 21 includes: first, splicing the several second sub-unit bodies into the second sub-assembly 22, and then splicing the second sub-assembly 22 and the first sub-assembly 21. Thus, the second sub-assembly 22 is divided into several second sub-unit bodies with moderate width, which facilitates the transportation of the second sub-assembly 22. Meanwhile, the several second sub-unit bodies are hoisted respectively, which reduces the hoisting weight during the installation of the second sub-assembly 22, facilitates the splicing of the second sub-assembly 22 and the first sub-assembly 21, and thus simplifies the installation process of the large-span gate and reduces the installation difficulty of the large-span gate. Figure 2 The second sub-assembly 22 includes several second sub-unit bodies, and the splicing of the second sub-assembly 22 and the first sub-assembly 21 includes: first, splicing the several second sub-unit bodies into the second sub-assembly 22, and then splicing the second sub-assembly 22 and the first sub-assembly 21. Thus, the second sub-assembly 22 is divided into several second sub-unit bodies with moderate width, which facilitates the transportation of the second sub-assembly 22. Meanwhile, the several second sub-unit bodies are hoisted respectively, which reduces the hoisting weight during the installation of the second sub-assembly 22, facilitates the splicing of the second sub-assembly 22 and the first sub-assembly 21, and thus simplifies the installation process of the large-span gate and reduces the installation difficulty of the large-span gate.

[0056] In the embodiment, the second sub-assembly units are first arranged on the upper end of the first sub-assembly 21, and the positions of the second sub-assembly units are confirmed; then the second sub-assembly units are arranged on the mounting platform, and the second sub-assembly units are spot-welded at the joint to obtain the second sub-assembly 22; finally, the second sub-assembly 22 is hoisted to the upper end of the first sub-assembly 21, and the second sub-assembly 22 and the first sub-assembly 21 are spliced. In this way, when the second sub-assembly units are arranged on the upper end of the first sub-assembly 21, the height is large, and it is difficult for the workers to access and spot-weld the joint of the second sub-assembly units. The second sub-assembly units are arranged on the mounting platform, and the height is small, so that the workers can easily access and spot-weld the joint of the second sub-assembly units, thereby facilitating the installation process of the large-span gate and reducing the installation difficulty of the large-span gate.

[0057] Optionally, the preparation of the first assembly, the second assembly and the third assembly comprises: pre-assembling the first assembly, the first sub-assembly units, the second sub-assembly units and the third assembly into a leaf.

[0058] The first assembly is the first unit 1, and the third assembly is the eighth unit 3. The width of the first unit 1 is 3500 mm, the height is 8500 mm, and the thickness is 3814 mm. The width of the eighth unit 3 is 3500 mm, the height is 8500 mm, and the thickness is 3814 mm. Meanwhile, the joint of the first unit 1 and the second unit 211 and the fifth unit 221 is spot-welded to strengthen the connection, and the joint of the eighth unit 3 and the fourth unit 213 and the seventh unit 223 is spot-welded to strengthen the connection.

[0059] In the embodiment, during the preparation of the first assembly, the second assembly and the third assembly, the first assembly, the first sub-assembly units, the second sub-assembly units and the third assembly are pre-assembled into a leaf, so that the first assembly, the first sub-assembly units, the second sub-assembly units and the third assembly can be combined into a leaf.

[0060] Optionally, the preparation of the first assembly, the second assembly and the third assembly further comprises: numbering the first assembly, the first sub-assembly units, the second sub-assembly units and the third assembly according to the installation sequence.

[0061] In the embodiment, the numbering is performed according to the installation sequence, so that the workers can accurately install the large-span gate according to the number, thereby facilitating the installation process of the large-span gate.

[0062] Optionally, the first component and the third component are arranged as an integral structure, and the height of the first component and the third component is equal to the height of the door leaf.

[0063] In the embodiment, the front side of the first component and the third component is provided with a supporting sliding block, and the two supporting sliding blocks are respectively arranged in the left side of the gate slot and the right side of the gate slot, and the supporting sliding block is made of engineering plastic alloy. Arranging the first component and the third component as an integral structure can ensure the installation accuracy of the supporting sliding block and ensure the effect of reducing the friction force between the large-span gate and the left side of the gate slot and the right side of the gate slot.

[0064] Meanwhile, the rear side of the first component and the third component is provided with a water seal structure, and the two water seal structures are respectively arranged in the left side of the gate slot and the right side of the gate slot, and the water seal structure is made of rubber material. Arranging the first component and the third component as an integral structure can ensure that the water seal structure is completely arranged on the first component and the third component, avoid segmenting the water seal structure, ensure that the water seal structure prevents water from entering the gate slot, and avoid the effect of rusting of the large-span gate and the supporting sliding block.

[0065] In addition, the left and right sides of the installation platform are provided with gate embedded parts, and the left side of the gate slot and the right side of the gate slot are respectively arranged in the left gate embedded part and the right gate embedded part. Since the first component and the third component are respectively connected with the left side of the gate slot and the right side of the gate slot, i.e., the left side of the first component is arranged in the left side of the gate slot, and the right side of the third component is arranged in the right side of the gate slot, and the distance between the left and right gate embedded parts is less than the width of the large-span gate. Therefore, the first component and the third component need to be installed by hoisting, and a lifting lug is arranged at the upper end of the first component and the third component, and the lifting lug is connected with a hook to hoist the first component and the third component. Arranging the first component and the third component as an integral structure can strengthen the structural strength of the first component and the third component, and avoid damage to the lower end of the first component and the third component due to stress during hoisting.

[0066] Optionally, the large-span gate installation method further comprises: welding and reinforcing the splicing part of the first component, the second component and the third component.

[0067] In the embodiment, during the assembly process, the first component, the second component and the third component are first spot-welded to be fixed; and when the door leaf is installed into the gate slot, the splicing part of the first component, the second component and the third component is welded and reinforced. Therefore, the structural strength of the door leaf composed of the first component, the second component and the third component can be improved. Meanwhile, the areas with large stress deformation are first welded, and the left and right sides of the door leaf can also be simultaneously welded and reinforced in a symmetrical manner to prevent deformation of the door leaf during the welding process.
