Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bridge engineering construction, and particularly relates to an air exchange auxiliary tooling for a steel box girder. Background Art
[0002] In the technical field of bridge engineering construction, the steel box girder is located below the bridge deck, and its interior is a relatively enclosed box structure. Ventilation openings are reserved on its side walls during factory production. The number of these ventilation openings is small and the aperture of the ventilation openings is small, so the ventilation effect is limited.
[0003] When it is necessary to perform in - position internal welding repair work on the U - ribs of an orthotropic steel bridge deck, during the in - position internal welding repair work of the U - ribs, a large amount of smoke and dust will be generated and accumulate inside the steel box girder, deteriorating the construction environment inside the steel box girder. Moreover, construction workers need to stay inside the steel box girder for a long time to carry out construction.
[0004] In order to solve the above - mentioned technical problems, it is necessary to additionally increase ventilation equipment to ventilate the steel box girder. The method in the prior art is to transport the fan into the steel box girder and then connect the power supply to ventilate the inside of the steel box girder. At this time, if manual handling is used, there is a technical problem that it is difficult to handle due to the large weight of the fan itself. If mechanical equipment such as a crane is used for handling, there is a problem of high usage fees, increasing the construction cost. Therefore, how to effectively and conveniently improve the construction environment inside the steel box girder is a difficult problem that urgently needs to be solved. Content of the Utility Model
[0005] Therefore, the utility model provides an air exchange auxiliary tooling for a steel box girder, which can facilitate the transportation, protection and use of the ventilation equipment, and thus effectively and conveniently improve the construction environment inside the steel box girder.
[0006] The technical solution adopted by the utility model is as follows:
[0007] An air exchange auxiliary tooling for a steel box girder includes a ventilation pipe and an auxiliary trolley located outside the steel box girder and including a mobile platform. The auxiliary trolley further includes a protective cover connected to the mobile platform and used to protect the ventilation equipment. The first end of the ventilation pipe is connected to the air inlet of the ventilation equipment, and the second end of the ventilation pipe is connected to the inner cavity of the steel box girder.
[0008] Furthermore, the protective cover includes a ventilation cover, a front panel and a rear panel. The ventilation cover is fixedly connected to the mobile platform. The front panel and the rear panel are respectively fixedly connected to the front and rear sides of the ventilation cover. The front panel is provided with an air - outlet reserved hole and an air - inlet reserved hole for the ventilation pipe to pass through.
[0009] Furthermore, a handle is fixedly connected to the front panel and / or the rear panel.
[0010] Furthermore, a plurality of ventilation slots are provided in the ventilation hood and / or the rear panel.
[0011] Furthermore, an observation hole is provided in the front panel.
[0012] Furthermore, a spare hole for the passage of a circuit or a reserved hole for installing an aviation plug is provided in the front panel.
[0013] Furthermore, the ventilation duct is a flexible hose or a corrugated pipe.
[0014] Furthermore, the second end of the ventilation duct is branched into two or more ventilation duct openings, and the two or more ventilation duct openings are respectively extended to different construction positions inside the steel box girder.
[0015] Furthermore, the mobile platform is provided with a locking device.
[0016] Furthermore, the moving member of the mobile platform is a universal wheel.
[0017] The steel box girder is located below the bridge deck, making it extremely inconvenient to enter and exit and the internal space is relatively enclosed. Based on the unique construction scenario inside the steel box girder, the steel box girder ventilation auxiliary tooling provided by the present utility model includes a ventilation duct and an auxiliary trolley with a mobile platform. The auxiliary trolley has an internal space formed by its protective cover and the mobile platform for accommodating the ventilation equipment, and the ventilation equipment is placed in this internal space. The presence of the protective cover of the auxiliary trolley effectively prevents external soot and dust from entering the ventilation equipment, thereby improving the working efficiency of the ventilation equipment and extending the service life of the ventilation equipment; the mobile platform of the auxiliary trolley facilitates the movement and transportation of a relatively heavy blower by itself. When the ventilation equipment is working, the auxiliary trolley carrying the ventilation equipment is pushed onto the corresponding bridge deck of the steel box girder, one end of the ventilation duct is connected to the air inlet of the ventilation equipment, and the other end is connected to the inner cavity of the steel box girder for ventilation.
[0018] First, the steel box girder ventilation auxiliary tooling provided by the present utility model changes the traditional method of transporting the ventilation equipment into the steel box girder by adding a ventilation duct to the ventilation equipment, that is, directly placing the ventilation equipment on the corresponding bridge deck of the steel box girder, and both ends of the ventilation duct are respectively communicated with the air inlet of the ventilation equipment and the inner cavity of the steel box girder, so as to complete the ventilation of the internal space of the steel box girder, realizing the efficient, low-cost and convenient improvement of the construction environment inside the steel box girder; second, the steel box girder ventilation auxiliary tooling provided by the present utility model includes an auxiliary trolley with a mobile platform, and the ventilation equipment is placed on the auxiliary trolley to realize the convenient movement and transportation of the ventilation equipment; third, the steel box girder ventilation auxiliary tooling also includes a protective cover, which can prevent external soot and dust from entering the ventilation equipment, thereby improving the working efficiency of the ventilation equipment and extending the service life of the ventilation equipment.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.
[0027] As Figures 1-4 shown, this embodiment provides a steel box girder ventilation auxiliary tooling, including a ventilation duct 12 and an auxiliary trolley. The ventilation equipment 1 is taken as an example of a fan. The auxiliary trolley includes a mobile platform 2 and a protective cover. The protective cover is fixedly connected to the mobile platform 2. The protective cover encloses the fan inside it to protect its normal operation. The mobile platform 2 is used to carry the fan to facilitate the movement and transportation of the fan. When it is necessary to ventilate the internal space of the steel box girder, one end of the ventilation duct 12 is connected to the air inlet 4 of the fan, and the other end surrounds the outer wall of the steel box girder and then accesses the inner cavity of the steel box girder for ventilation.
[0028] In specific practice, the steel box girder is located below the bridge deck, making it extremely inconvenient to access and the internal space is relatively enclosed. Based on the unique construction scenario inside the steel box girder, the steel box girder ventilation auxiliary tooling provided by the present utility model includes a ventilation pipe 12 and an auxiliary trolley with a mobile platform 2. The auxiliary trolley has an internal space formed by its protective cover and the mobile platform 2 for accommodating the fan, and the fan is placed in this internal space. The presence of the protective cover of the auxiliary trolley effectively prevents external soot and dust from entering the fan, thereby improving the working efficiency of the fan and extending the service life of the fan; the mobile platform 2 facilitates the movement and transportation of the fan with a relatively large self-weight. When the fan needs to work, the auxiliary trolley carrying the fan is pushed onto the corresponding bridge deck of the steel box girder, one end of the ventilation pipe 12 is connected to the air inlet 4 of the fan, and the other end is connected to the inner cavity of the steel box girder for ventilation.
[0029] First of all, the steel box girder ventilation auxiliary tooling provided by the present utility model changes the traditional method of transporting the fan into the steel box girder by adding a ventilation pipe 12 to the fan, that is, directly placing the fan on the corresponding bridge deck of the steel box girder. The two ends of the ventilation pipe 12 are respectively connected to the air inlet 4 of the fan and the inner cavity of the steel box girder, and the ventilation of the internal space of the steel box girder can be completed, realizing the improvement of the construction environment inside the steel box girder efficiently, at low cost and conveniently; secondly, the steel box girder ventilation auxiliary tooling provided by the present utility model includes an auxiliary trolley with a mobile platform 2, and the fan is placed on the auxiliary trolley to realize the convenient movement and transportation of the fan; thirdly, the steel box girder ventilation auxiliary tooling also includes a protective cover, which can prevent external soot and dust from entering the fan, thereby improving the working efficiency of the fan and extending the service life of the fan.
[0030] In this embodiment, the mobile platform 2 and the protective cover are detachably connected. The advantage of this setting is that it is convenient to take out the ventilation equipment 1 from the auxiliary trolley when the ventilation equipment 1 fails and needs to be repaired or replaced. In a specific implementation manner, the mobile platform 2 and the protective cover can also be fixedly connected.
[0031] In this embodiment, the ventilation equipment 1 is fixedly connected to the mobile platform 2. The advantage of this setting is that it avoids the relative movement between the ventilation equipment 1 and the mobile platform 2 of the auxiliary trolley during the movement or transportation, and effectively avoids phenomena such as rubbing and collision between the ventilation equipment 1 and the side wall of the auxiliary trolley.
[0032] In this embodiment, the protective cover includes a ventilation cover 8, a front panel 6 and a rear panel 7. The ventilation cover 8 is fixedly connected to the mobile platform 2, and the front panel 6 and the rear panel 7 are respectively fixedly connected to the front and rear sides of the ventilation cover 8. The front panel 6 is provided with an air outlet reserved hole 10 and an air inlet reserved hole 9 for the ventilation pipe 12 to pass through.
[0033] In a specific embodiment, it further includes a ventilation duct connecting the air outlet 3 of the ventilation equipment 1 to the outside.
[0034] To provide protection for the auxiliary trolley, the bottom sides of the front panel 6 and the rear panel 7 are buckled on the edge of the mobile platform 2 and fixed by bolts. The left and right end faces of the ventilation hood 8 are buckled on the edge of the mobile platform 2 and fixed by bolts. The edges of the front panel 6 and the rear panel 7 are provided with bending sections, and the bending sections are located inside the ventilation hood 8. The ventilation hood 8 is fixedly connected to the bending sections.
[0035] In a specific embodiment, when installing the ventilation hood 8, the front panel 6 and the rear panel 7, the bottom sides of the front panel 6 and the rear panel 7 are buckled on the edge of the mobile platform 2 and bolted. Then, the front and rear edges of the ventilation hood 8 are buckled above the edges of the front panel 6 and the rear panel 7 and bolted. Finally, the left and right end faces of the ventilation hood 8 are buckled on the edge of the mobile platform 2 and fixed by bolts. Since the ventilation hood 8 is arched, it is prone to deformation when there is no support at the top. By fixedly connecting the bending parts of the front panel 6 and the rear panel 7 to the ventilation hood 8, the front panel 6 and the rear panel 7 can support the top surface of the ventilation hood 8, improving the top protection of the auxiliary trolley.
[0036] To facilitate the staff to push the auxiliary trolley carrying the ventilation equipment 1, the front panel 6 and / or the rear panel 7 can be provided with a handle 13. In a specific embodiment, the number of handles 13 can be one or more, and the installation position of the handle 13 can also be outside the ventilation hood 8.
[0037] To facilitate the heat dissipation of the ventilation equipment 1, the ventilation hood 8 and / or the rear panel 7 can be provided with a plurality of ventilation slots.
[0038] To facilitate observing the operation of the ventilation equipment 1, the front panel 6 can be provided with an observation hole 11.
[0039] To facilitate connecting the ventilation equipment 1 to an external power source, the front panel 6 can be provided with a spare hole for the passage of wires or a reserved hole for installing an aviation plug.
[0040] In this embodiment, the ventilation duct 12 is a flexible hose, and the advantage is that the pipeline dredging direction can be changed according to needs, facilitating its connection to the inner cavity of the steel box girder through the side wall of the steel box girder. In a specific embodiment, the ventilation duct 12 can also be a corrugated pipe, or other ventilation ducts that meet certain rigidity requirements and can change the pipeline dredging direction.
[0041] In a specific embodiment, the second end of the ventilation duct can be split into two or more ventilation duct openings, and each of the two or more ventilation duct openings extends to different construction positions within the steel box girder that require dust removal and ventilation. The advantage of this setting is that, according to the specific construction needs within the steel box girder, the same ventilation device 1 can be used to ventilate and remove dust from different construction positions simultaneously.
[0042] To facilitate the control of the movement of the auxiliary trolley, the moving platform 2 of the auxiliary trolley provided by the present utility model is provided with a locking device. When ventilating the steel box girder, the moving platform 2 is locked through the locking device, thereby fixing the position of the auxiliary trolley carrying the ventilation device 1. To enable the auxiliary trolley to move in all directions, the moving member of its moving platform 2 is a universal wheel 5 that can rotate 360° around its internal rotation axis.
