[0002] At present, the dismantling of large-span beam truss structures is difficult. According to the order of installation first and then dismantling, the truss system needs to be dismantled first. However, after the construction of the truss system is completed, the upper load is huge, and it is difficult to remove the truss. The dismantling process is time-consuming and labor-intensive, and it is also prone to safety accidents. After the construction is completed, the upper structure itself has the supporting capacity. By lowering the truss position by a few centimeters through the unloading block, the load of the upper structure can be removed from the truss system, so as to achieve the purpose of easily dismantling the truss structure. The current unloading device is relatively complicated to install and unload. Some unloading devices have poor unloading effects and are prone to jamming. How to make the entire unloading device easier to install and operate, and can be reused many times to meet the needs of the construction site is an urgent problem to be solved.

[0019] 1. An integrated hydraulic unloading device for dismantling trusses of a beam truss structure of the present invention is used. When a large-span beam truss is under construction in an engineering project, it is supported at the bottom of the truss. After the construction is completed, the unloading rod is rotated to make the oil hole coincide with the connecting pipe, so that the pressure chamber and the oil storage chamber are connected, so that the liquid oil in the pressure chamber flows into the oil storage chamber, the oil pressure in the pressure chamber drops, the pressure seat drops, the truss drops, and the truss load is converted into oil pressure that is easy to unload.

[0034] Please refer to Figure 1 and 2 An embodiment of the present invention provides an integrated hydraulic unloading device for dismantling a truss of a beam truss structure, comprising a housing 1, a connecting pipe 4, a pressure bearing seat 2, and an unloading rod 3.

[0035] Combination Figure 3 , 4 As shown in Figures 1 and 5, the housing 1 is provided with a pressure chamber 5 and an oil storage chamber 6 spaced apart from each other, and liquid oil 10 is stored in the pressure chamber 5 and the oil storage chamber 6. The shapes of the housing 1, the pressure chamber 5 and the oil storage chamber 6 can be flexibly set according to the actual application scenario. For example, in this embodiment, the housing 1 is a cylinder with a closed lower end, the pressure chamber 5 is cylindrical, and the oil storage chamber 6 is approximately hemispherical. The housing 1, the pressure chamber 5 and the oil storage chamber 6 are coaxially arranged.

[0036] The connecting pipe 4 is connected between the pressure chamber 5 and the oil storage chamber 6, and the lower end of the connecting pipe 4 extends to the bottom of the oil storage chamber 6. Specifically, a vertically arranged connecting hole 8 is provided between the pressure chamber 5 and the oil storage chamber 6, and the connecting hole 8 is coaxially arranged with the pressure chamber 5. The connecting pipe 4 is vertically arranged, and the upper end is connected to the lower end of the connecting hole 8 and extends to the bottom surface of the pressure chamber 5. The lower end of the connecting pipe 4 extends to the bottom of the oil storage chamber 6 and does not contact the bottom surface of the oil storage chamber 6.

[0037] like Figure 6 As shown, the bottom of the pressure-bearing seat 2 can be vertically slidably connected to the upper part of the pressure-bearing chamber 5. Specifically, a pressure plate 9 is provided at the bottom of the pressure-bearing seat 2, and the pressure plate 9 is embedded in the pressure-bearing chamber 5 and can slide vertically. In order to ensure the seal between the pressure plate 9 and the inner wall of the pressure-bearing chamber 5, the side wall of the pressure plate 9 is provided with a first sealing ring 11, and the pressure plate 9 contacts the inner wall of the pressure-bearing chamber 5 through the first sealing ring 11.

[0038] In some embodiments, the pressure-bearing seat 2 is in an I-shape, which can, on the one hand, allow the upper portion of the pressure-bearing seat 2 to stably support the truss, and, on the other hand, facilitate pulling the pressure-bearing seat 2 to slide upward.

[0039] In some embodiments, the pressure-bearing seat 2 is provided with height scale marks along the vertical direction, and the vertical distance that the pressure-bearing seat 2 slides relative to the pressure-bearing chamber 5 can be accurately determined by the height scale marks.

[0040] like Figure 7 As shown, the unloading rod 3 can rotate through the housing 1, and an oil hole 7 is provided in the middle of the unloading rod 3. The unloading rod 3 can rotate to make the oil hole 7 coincide with the connecting pipe 4 or staggered with the connecting pipe 4.

[0041] Specifically, a horizontally penetrating mounting hole 12 is provided in the housing 1 between the pressure chamber 5 and the oil storage chamber 6, the mounting hole 12 is arranged to intersect the connecting hole 8 vertically, and the unloading rod 3 can rotatably penetrate the mounting hole 12. In order to prevent the liquid oil 10 from leaking from the mounting hole 12, the portions of the unloading rod 3 located on both sides of the connecting hole 8 are provided with second sealing rings 13, and the contact portion between the unloading rod 3 and the inner wall of the mounting hole 12 is sealed by the second sealing rings 13.

[0042] In order to facilitate the rotation of the unloading rod 3, at least one end of the unloading rod 3 is provided with a handle 14, and the unloading rod 3 can be easily rotated by holding the handle 14. As in this embodiment, the unloading rod 3 is provided with handles 14 at both ends.

[0043] In order to control the rotation of the unloading rod 3 so that the oil hole 7 coincides with the connecting tube 4 or is offset from the connecting tube 4, the unloading rod 3 is provided with angle scale marks, which are arranged on the outer wall of the unloading rod 3 and are arranged circumferentially around the unloading rod 3. By observing the rotation angle of the unloading rod 3, the relative position state of the oil hole 7 in the unloading rod 3 and the connecting tube 4 can be judged.

[0044] The process of dismantling a large-span beam truss by using the integrated hydraulic unloading device for dismantling the truss of a beam truss structure of the present invention is as follows:

[0045] During the construction of the engineering project, the integrated hydraulic unloading device for dismantling the trusses of the beam-type truss structure of the present invention is supported at the bottom of the truss. At this time, the oil hole 7 is relatively staggered with the connecting pipe 4, and the connecting pipe 4 between the pressure chamber 5 and the oil storage chamber 6 is separated by the outer wall of the unloading rod 3. The integrated hydraulic unloading device for dismantling the trusses of the beam-type truss structure of the present invention supports the truss through the oil pressure in the pressure chamber 5.

[0046] After the construction of the project is completed, the unloading rod 3 is rotated, the oil hole 7 overlaps with the connecting pipe 4, so that the connecting pipe 4 between the pressure chamber 5 and the oil storage chamber 6 is opened, and part of the liquid oil 10 in the pressure chamber 5 flows into the oil storage chamber 6 along the connecting pipe 4, and the air in the upper part of the pressure chamber 5 is compressed, so that the pressure seat 2 moves downward, thereby unloading the truss. Since air is easier to compress than liquid oil 10, the pressure seat 2 can slide down easily.

[0047] It should be noted that when the pressure seat 2 moves downward, when the truss is unloaded to the desired height, the unloading rod 3 can be rotated to stagger the oil hole 7 and the connecting pipe 4, so that the pressure seat 2 is locked. Compared with the traditional unloading device, which is difficult to adjust its own height according to the construction site environment, the integrated hydraulic unloading device for dismantling the truss of the beam truss structure of the present invention can adjust the height of the pressure seat 2 by adjusting the unloading rod 3 to control the amount of oil in the pressure chamber 5, thereby accurately adjusting the height of the truss.

[0048] After the whole truss is disassembled and removed, the integrated hydraulic unloading device for dismantling the truss of the beam truss structure of the present invention is removed, the unloading rod 3 is rotated to overlap the oil hole 7 with the connecting pipe 4, the pressure seat 2 is lifted, and the liquid oil 10 in the oil storage chamber 6 is slowly sucked into the pressure chamber 5, and then the unloading rod 3 is rotated to stagger the oil hole 7 with the connecting pipe 4, so that the pressure chamber 5 is sealed, and the integrated hydraulic unloading device for dismantling the truss of the beam truss structure of the present invention can bear pressure again, so it can be used repeatedly. By observing the height scale mark on the pressure seat 2, it can be ensured that the height of the pressure seat 2 meets the use requirements of the next project.

[0049] In this article, the directional words such as front, back, top, and bottom involved are defined by the positions of the parts in the drawings and the positions of the parts relative to each other, just for the sake of clarity and convenience in expressing the technical solution. It should be understood that they are relative concepts and can change accordingly according to different ways of use and placement, and the use of the directional words should not limit the scope of protection claimed in this application.
