Description

Technical Field

[0001] The invention relates to the field of equipment manufacturing, and in particular to an assembly system for a bridge steel box girder diaphragm and a bottom plate. Background Art

[0002] The steel box girder of a bridge is generally made up of a bottom plate, a web plate, a transverse diaphragm, a longitudinal diaphragm, etc. connected by a full welding method, wherein the plates need to be assembled first and then welded.

[0003] Among them, when assembling the diaphragm and the bottom plate, the current method is to use a lifting equipment to move it above the bottom plate, and then lower the lifting equipment to make the diaphragm fall on the bottom plate. However, this method can only ensure that the diaphragm falls on the bottom plate, but cannot accurately adjust its position, resulting in a large assembly error, affecting the overall quality of the steel box girder, such as stress effect and structural strength. At the same time, due to the large number of diaphragms and the fact that the diaphragms can only be positioned one by one at present, it further leads to low production efficiency of the steel box girder and cannot meet the needs of mass production. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] like Figure 1-3 As shown, the bridge steel box girder includes: a bottom plate 1, a corrugated steel web 2 vertically connected to the bottom plate 1 at the top, a connecting plate 4 vertically connected to the bottom of the corrugated steel web 2, and a partition 3 vertically connected to the bottom plate 1; there are two groups of corrugated steel webs 2, which are relatively parallelly arranged, each partition 3 is located between two groups of corrugated steel webs 2, and each partition 3 is perpendicular or nearly perpendicular to the corrugated steel webs 2 on both sides.

[0034] On this basis, this embodiment provides a bridge steel box girder diaphragm and bottom plate assembly system, such as Figure 4-5 As shown, it includes:

[0035] A bottom plate support block 10, which is used to support the bottom plate 1. In this embodiment, there are a plurality of bottom plate support blocks 10, which are arranged along the length direction and / or width direction of the bottom plate 1;

[0036] A linear guide rail 20, which is arranged on the side of the bottom plate 1 supported by the bottom plate support block 10 and extends along the length direction of the bottom plate 1. In this embodiment, there are two groups of linear guide rails 20, which are respectively located on both sides of the bottom plate support block 10 and the bottom plate 1;

[0037] a partition support rib 70 connected to the surface of the partition 3;

[0038] A partition bottom slot 30, which is provided at the bottom of the partition 3;

[0039] Bottom plate rib 40, which is vertically connected to the bottom plate 1 and is used to cooperate with the bottom slot 30 of the partition;

[0040] The partition support mechanism 50 is used to support the partition 3 by cooperating with the partition support rib 70 after the partition bottom slot 30 of a partition 3 cooperates with the bottom plate rib 40 of the bottom plate 1 (such as snapping), so that the partition 3 and the bottom plate 1 remain perpendicular to complete the positioning of the partition 3 on the bottom plate 1; in this embodiment, the partition support mechanism 50 includes a hydraulic push rod, one end of which cooperates with the partition support rib on the surface of the partition 3 (such as snapping), and the other end is detachably connected to the surface of the bottom plate 1 to support the partition 3 to prevent the partition 3 from tipping over, and at the same time, the inclination angle of the partition 3 is finely adjusted through telescopic movement to keep it perpendicular to the bottom plate 1, thereby completing the positioning of the partition 3 on the bottom plate 1;

[0041] A moving unit 60, which cooperates with the linear guide rail 20 through a slider 601 and can slide along the linear guide rail 20;

[0042] The partition plate positioning clamping assembly is connected to the moving unit 60 and is used to clamp the side of a partition plate 3 after it is supported by the partition plate supporting mechanism 50 to prevent the partition plate 3 from tilting, so as to facilitate the subsequent welding of the joint between the bottom plate 1 and the partition plate 3 by the welding unit to ensure the assembly accuracy;

[0043] And a bottom plate height adjustment mechanism 80 (such as a telescopic cylinder, etc.), which is arranged below the bottom plate 1 and is used to adjust the height position of the bottom plate 1.

[0044] When in use, the bottom plate 1 is first moved to above the bottom plate support block 10 by means of a crane hoisting device, and then the bottom plate 1 is slowly dropped so that the bottom plate 1 is supported by the bottom plate support block 10;

[0045] A partition 3 is hoisted above the bottom plate 1 using a crane hoisting device, and then the partition 3 is slowly lowered until the bottom slot 30 of the partition is matched with the bottom plate rib 40 (such as snap-fitting);

[0046] The partition 3 is supported by the partition support mechanism 50, and the partition 3 is kept vertical to the bottom plate body 11 of the bottom plate 1 by fine adjustment of the partition support mechanism 50, so as to complete the positioning of the partition 3 on the bottom plate 1, and then the lifting equipment is removed;

[0047] The partition plate positioning and clamping assembly and the moving unit 60 slide as a whole along the linear guide rail 20 to the side of the partition plate 3, the partition plate positioning and clamping assembly clamps the partition plate 3, and then the partition plate supporting mechanism 50 is removed;

[0048] The welding unit welds the joint between the bottom plate 1 and the partition 3. After the welding is completed, the partition positioning clamping assembly releases the clamping of the partition 3 to release the welded partition 3, thereby completing the assembly of the bottom plate 1 and the partition 3.

[0049] Repeat the above steps to complete the assembly of several partitions 3 and the bottom plate 1.

[0050] Therefore, in the assembly system of this embodiment, the assembly of the partition 3 and the bottom plate 1 can be quickly completed in cooperation with the lifting equipment to greatly improve the work efficiency. At the same time, the partition 3 can be accurately positioned by the partition support mechanism 50 to ensure the assembly quality. Furthermore, the assembly accuracy of the bottom plate 1 and the partition 3 is also ensured by a movable partition positioning clamping assembly.

[0051] Embodiment 2:

[0052] The difference between this embodiment and embodiment 1 is that Figure 6 The partition positioning and clamping assembly includes: a mounting frame 300; a clamping jaw driving mechanism 301 (such as a cylinder, etc.), which is connected to the mounting frame 300; and a clamping jaw 302, which is connected to the clamping jaw driving mechanism 301 and can be opened and closed under the control of the clamping jaw driving mechanism 301 to achieve clamping / releasing of the side of the partition 3; and a pushing mechanism 303 (such as a cylinder, a hydraulic cylinder, etc.), which is installed on the moving unit 60 and connected to the mounting frame 300, and is used to drive the mounting frame 300, the clamping jaw driving mechanism 301, and the clamping jaw 302 to move synchronously toward the side of the partition 3 / away from the side of the partition 3.

[0053] The partition positioning clamping assembly and the moving unit 60 slide as a whole along the linear guide rail 20 to the side of the partition 3, and the jaw driving mechanism 301 drives the jaw 302 to open, and then the pushing mechanism 303 drives the mounting frame 300, the jaw driving mechanism 301, and the jaw 302 to move synchronously toward the partition 3 through telescopic movement, and the jaw driving mechanism 301 drives the jaw 302 to close to complete the clamping of the partition 3; after the welding of the joint between the base plate 1 and the partition 3 is completed, the jaw driving mechanism 301 drives the jaw 302 to open again, and the pushing mechanism 303 drives the mounting frame 300, the jaw driving mechanism 301, and the jaw 302 to move synchronously away from the partition 3 through telescopic movement to release the partition 3 that has been welded.

[0054] Embodiment 3:

[0055] The difference between this embodiment and embodiment 1 or 2 is that Figure 6 As shown, there are several (such as 3) clamping drive mechanisms 301, which are sequentially connected to the mounting frame 300 from top to bottom in the height direction. Correspondingly, there are also several (such as 3) clamping jaws 302, and each clamping jaw 302 is correspondingly connected to a clamping drive mechanism 301. Thus, different positions of the side of the partition 3 can be clamped by the several clamping jaws 302 arranged along the height direction to firmly fix the relative position of the partition 3 and the base plate 1, thereby avoiding position displacement during welding and affecting the welding quality.

[0056] Embodiment 4:

[0057] The difference between this embodiment and any one of the embodiments 1-3 is that Figure 4 As shown, an oblique guide plate 101 extends from the upper end surface of the bottom plate support block 10, whereby the bottom plate 1 can slide along the oblique guide plate 101 onto the bottom plate support block 10 to be supported by the bottom plate support block 10, thereby realizing rapid positioning of the bottom plate 1.

[0058] Embodiment 5:

[0059] The only difference between this embodiment and any of the embodiments 1-4 is that the bridge steel box girder diaphragm and bottom plate assembly system in this embodiment further includes:

[0060] The control system is connected to a plurality of partition support mechanisms 50 and is used to control the plurality of partition support mechanisms 50 to operate simultaneously, thereby achieving simultaneous adjustment of the positions of a plurality of partitions 3, thereby greatly improving work efficiency.

[0061] In summary, the bridge steel box girder partition and base plate assembly system of the present invention can cooperate with the lifting equipment to quickly complete the assembly of the partition 3 and the base plate 1, so as to greatly improve the work efficiency. At the same time, the partition 3 can be accurately positioned by the partition support mechanism 50 to ensure the verticality of the base plate 1 and the partition 3. Furthermore, the assembly accuracy of the base plate 1 and the partition 3 is ensured by a movable partition positioning clamping assembly, thereby ensuring the quality of the welding assembly.
