Description

Technical FieldThe present invention relates to the technical field of maintenance of box beams, and more particularly to a maintenance apparatus for a box beam.Prior ArtAs the quality standards for box carriers become more stringent, conventional maintenance methods are difficult to meet requirements. Conventional maintenance techniques have many shortcomings. One of these is that a fixed spraying method is used for maintenance in the inner cavity of the hollow box carrier, in which method the concrete of the box body is sprayed and sprayed via the spray nozzles of the spray pipes. However, the fixed spray method has uneven spray widths and uneven spray distribution, and tends to form "water spots" on the concrete surface, which deteriorates the appearance of the support body. A second drawback is the water storage maintenance of the bottom plate of the hollow box beam, which requires the construction of a water storage basin and the construction of enclosures, which increases the construction costs and the level of difficulty. At the same time, there are some potential safety risks in the water collection process, such as the collapse of the water collection basin and the lowering of the storage bar base during the maintenance process, which can lead to damage to operating personnel and equipment. The conventional maintenance methods are associated with a high level of personnel outlay and a high water requirement during the maintenance of the base plate and of the interior space of the hollow box carrier.Summary of the Utility ModelThe purpose of the invention is to provide a maintenance device for a box carrier to solve the problems of high personnel costs and high water requirements when maintaining the floor panel and the interior of the box carrier in the conventional maintenance methods described in the prior publication.The utility model provides a maintenance device for a box carrier, comprising a housing, a box end maintenance tool, and a humidification device; wherein the housing is provided at the bottom of the box carrier; the housing forms an annular region along an edge of a bottom surface of the box carrier; an upper part of the housing abuts a bottom of the box carrier; the box end maintenance tools are configured to close two ends of an inner cavity of the box carrier; and the humidification device is configured to supply mist to the bottom of the box carrier and the inner cavity of the box carrier.The maintenance device for the box carrier described in the present application comprises a housing, wherein the housing is located on the underside of the box carrier and forms an annular region along the edge of the underside of the box carrier, so that an annular region is formed on the underside of the box carrier.

At the same time, the upper part of the casing 2 abuts the bottom of the hollow box beam 1 so that the casing 2 forms a maintenance space at the bottom of the hollow box beam 1, and then closes two ends of the inner cavity of the hollow box beam 1 via a box end maintenance device 3, and then sends mist via the humidification device 4 into the maintenance space at the bottom of the hollow box beam 1 and into the inner cavity of the hollow box beam 1 to maintain the bottom of the hollow box beam 1 and the inner cavity of the hollow box beam 1, thereby achieving comprehensive maintenance of the bottom surface of the hollow box beam 1 and the concrete surface of the hollow box beam 1 to maintain the bottom of the box beam 1 and the inner cavity of the box beam 1, thereby reducing the labor. Further, by the case 2 at the bottom of the box beam 1 and the box end maintenance device 3, the bottom and the inner cavity of the box beam 1 are closed so that the inner cavity of the box beam 1 and the bottom plate of the box beam 1 are both in the closed space, and the water atomization maintenance method is used, thereby effectively improving the concrete maintenance quality of the lower surface of the hollow box beam 1 and the inner cavity of the hollow box beam 1.In one or more embodiments, as shown in Figures 1 and 3, it further comprises a piping system 5 through which the humidification device 4 discharges mist to the bottom of the box beam 1 and into the cavity of the box beam 1.

One end of the inner cavity air duct 53 is connected to the lower air duct 52, and the other end of the inner cavity air duct 53 extends into the inner cavity of the box beam 1 via the water discharge opening of the bottom plate of the box beam 1.In an alternative embodiment, the moistening device 4 is an automatic ultrasonic spray moistening device for supplying mist to the bottom of the box carrier 1 and to the interior of the box carrier 1.In one or more embodiments, the housing 2 includes baffles circumferentially disposed along the edge of the bottom surface of the box beam 1 and columns connected to the baffles, the columns spaced along the length of the baffles.Here, the baffle plate is a colored steel plate, the column is a square steel, and the baffle plate is supported and reinforced by the square steel. The housing 2 is arranged around the maintenance base 6 and corresponds to the height of the maintenance base 6. After being raised onto the maintenance base 6, the box carrier 1 forms a closed space, i.e. the housing 2 and the underside of the box carrier 1 form a maintenance space.In one or more embodiments, as shown in FIG. 2, the carrier end maintenance device 3 includes a tool frame 31 and a resin sheet 32, the tool frame 31 is disposed at the end portion of the inner cavity of the box carrier 1, and the resin sheet 32 covers the tool frame 31. Before the maintenance of the case carrier 1, the tool frame 31 is installed at the end of the inner cavity of the case carrier 1, the resin sheet 32 is laid over the tool frame 31, and the inner cavity of the case carrier 1 is sealed by the resin sheet 32 and the tool frame 31, so that a sealed space is formed in the inner cavity of the case carrier 1. In this way, the subsequent moistening device 4 can emit mist into the interior of the box beam 1 in order to achieve the maintenance of the surface concrete of the interior of the hollow box beam 1.Here, the size of the tool frame 31 is set according to the size of the end face of the box beam 1. The tool frame 31 is welded from 20×20×2 mm square steel. The tool frame 31 is wrapped with geotextile and flat iron, and the plastic film 32 is laid over the tool frame 31 to close the interior of the hollow box carrier 1.In an alternative embodiment, as shown in FIG. 2, the box end maintenance tool 3 further comprises a support frame 33 and a peripheral frame 34. the peripheral frame 34 is arranged along the outer edge of the end portion of the box carrier 1.One end of the support frame 33 is connected to the peripheral frame 34, and the other end of the support frame 33 is connected to the tool frame 31.The peripheral frame 34 is disposed along the outer edge of the end portion of the case carrier 1. The peripheral frame 34 is located outside the tool frame 31 and surrounds the tool frame 31, and then the peripheral frame 34 and the tool frame 31 are supported and fixed by the peripheral frame 34 and the support frame 33 to ensure the stability of the tool frame 31.Here, the peripheral frame 34 is fixedly attached to the outer edge of the end portion of the case carrier 1.In an alternative embodiment, the support frame 33 is arranged circumferentially along the tool frame 31.Example 2Based on Example 1, the maintenance apparatus for the box carrier according to the present embodiment further includes, as shown in FIG. 3, a maintenance pedestal 6 disposed in the annular region to support the bottom of the box carrier 1.During maintenance, the box carrier falls onto a maintenance base 6 which supports the bottom of the box carrier 1.In one or more embodiments, as shown in FIGS. 4 and 5, the maintenance base 6 includes a base base 61 and a lifting bracket 62 provided on the base base 61, the lifting bracket 62 being used for adjusting the vertical height of the hollow box carrier 1.Before lowering the carrier, first, the lifting support 62 is controlled to be raised so that the lower surface of the hollow box carrier 1 falls on the lifting support 62, and then the lifting support 62 is controlled to be lowered so that the box carrier 1 is slowly lowered until the lower surface of the box carrier 1 contacts the housing 2 to prevent the housing 2 from being damaged and not closing tightly because the box carrier 1 abuts against the housing 2 due to vibrations during the lifting operation.In an alternative embodiment, as shown in FIGS. 6 and 7, the lift bracket 62 includes a frame 621, a telescoping cylinder 622, a support plate 623, and a lift plate 624.The support plate 623 is connected to the top of the frame 621, and a lifting plate 624 is movably disposed inside the support plate 623.The telescopic cylinder 622 is mounted in the frame 621, and a telescopic rod of the telescopic cylinder 622 is connected to the lifting plate 624.The telescopic cylinder 622 is mounted in the frame 621, the frame 621 is connected to the base 61, and the telescopic rod of the telescopic cylinder 622 is connected to the lifting plate 624. By controlling the telescopic cylinder 622, the up and down movement of the lifting plate 624 is controlled. When the box carrier 1 falls downward, first, the telescopic cylinder 622 is controlled to move upward, so that the lifting plate 624 is lifted and located above the support plate 623, as illustrated in FIGS. 4 and 5. Thereby, the lower part of the box carrier 1 falls on the lifting plate 624, and then the telescopic cylinder 622 is controlled to contract, so that the lifting plate 624 falls downward, thereby causing the box carrier 1 to fall slowly downward. When the bottom surface of the case carrier 1 comes into contact with the housing 2 to prevent the case carrier 1 from falling down directly, the case carrier 1 is shaken during the lifting operation to collide with the housing 2, resulting in damage to the housing 2 and improper sealing of the housing 2.Moreover, the support plate 623 is connected to the top of the frame 621, and the lifting plate 624 is movably disposed inside the support plate 623. After the lifting plate 624 is lowered to a height below the supporting plate 623 as shown in FIG. 6, the box carrier 1 falls on the supporting plate 623, and at this time, the supporting plate 623 supports the box carrier 1. Since the supporting plate 623 is connected to the upper surface of the frame 621, the weight of the box carrier 1 is transmitted to the base 61 via the frame 621, whereby a long-term force by the telescopic cylinder 622 is prevented and the box carrier 1 is stably supported.In the present application, the height of the top surface of the support plate 623 is the same as the height of the housing 2 to ensure that the bottom surface of the box carrier 1 abuts the housing 2 after the surface area of the box carrier 1 has fallen onto the support plate 623.In an alternative embodiment, as shown in FIG. 8, the frame 621 includes a bottom plate 6211, a top plate 6212, and vertical rods 6213.

The locking component 625 is divided into a first locking plate 6251 and a second locking plate 6252. A telescopic cylinder 622 is disposed between the first lock plate 6251 and the second lock plate 6252. The both ends of the first lock plate 6251 and the second lock plate 6252 abut on a vertical rod 6213 and the first lock plate 6251 and the second lock plate 6252 are connected to each other via a bolt. The telescopic cylinder 622 is clamped by the first lock plate 6251 and the second lock plate 6252 and fixed to the vertical rod 6213.Further, an L-shaped plate 626 is provided. On the outside of the vertical rod 6213, a spacer plate 6214 is attached. One side of the L-shaped plate 626 is fixed to the spacer plate 6214, and the other side of the L-shaped plate 626 is fixed to the support plate 623. The support plate 623 is reinforced by the L-shaped plate 626.The foregoing are only preferred embodiments of the utility model and are not intended to limit the utility model. All modifications, equivalents, and improvements within the spirit and spirit of the invention are intended to be included within the scope of the invention.The present invention relates to the technical field of box carrier maintenance and, more particularly, to a hollow box carrier maintenance apparatus comprising a housing, the housing being disposed on the lower surface of the hollow box carrier and forming an annular region along the edge of the lower surface of the hollow box carrier so as to form an annular region on the lower surface of the hollow box carrier.
