Description

Technical Field

[0001] This utility model belongs to the field of box girder maintenance technology, specifically relating to a railway box girder spray maintenance device. Background Technology

[0002] In railway bridge construction, box girders serve as the main load-bearing structure, and the quality of their concrete curing directly affects the long-term durability and operational safety of the bridge. Spray curing is a common method for curing box girder concrete. By continuously spraying water to keep the concrete surface moist, it promotes full cement hydration and prevents the formation of shrinkage cracks.

[0003] Currently, most existing railway box girder spray curing devices employ fixed nozzle installation structures. The nozzle positions are typically pre-set during manufacturing, making it impossible to flexibly adjust them according to the actual size, shape, or specific curing requirements of the box girder. This fixed structure has significant limitations: firstly, for different types of box girders, the nozzle coverage may be insufficient or excessive, leading to uneven curing and affecting concrete strength development; secondly, fixed nozzles cannot target specific areas of the box girder (such as the web or bottom slab) for focused curing, reducing the targeted nature and effectiveness of the curing process. Therefore, there is an urgent need in this field for a spray curing device that allows for flexible and rapid nozzle position adjustment to adapt to diverse box girder curing needs and improve curing efficiency and quality.

[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown: A railway box girder spraying maintenance device includes a nozzle 1, a mounting base 2, a connector 3, and two upright baffles 4. The passage between the two baffles 4 serves as the box girder placement area. The mounting base 2 is distributed on the inner side of the two baffles 4. The nozzle 1 is installed on the connector 3. The nozzle 1 is optionally connected to the mounting base 2 through the connector 3. The water supply pipe connected to the nozzle 1 is a flexible hose.

[0019] The mounting brackets 2 are arranged in a rectangular array on the baffle 4, providing a variety of installation points. Users can select the optimal nozzle layout according to the specific shape of the box girder and the maintenance requirements to achieve comprehensive and uniform spraying maintenance and improve the quality of concrete curing.

[0020] like Figure 4 , Figure 5 As shown: Card holder 2 has a first slot 2.1 perpendicular to baffle 4, and the bottom of the first slot 2.1 is provided with an open slot 2.2; plug-in seat 3 has a second slot 3.1, the second slot 3.1 of plug-in seat 3 can be inserted into the first slot 2.1 of card holder 2, and the plug-in seat 3 is provided with a locking mechanism, which can be engaged with card holder 2 through slot 2.2.

[0021] The connector 3 also includes a push rod 3.3, which is slidably inserted into the guide hole at the bottom of the second slot 3.1. A push plate 3.4 is provided at one end of the push rod 3.3 that passes through the second slot 3.1, and a mounting plate is provided at the exposed end of the push rod 3.3. The nozzle 1 is fixed on the mounting plate. A first spring 3.5 is fitted on the push rod 3.3 between the push plate 3.4 and the bottom of the second slot 3.1. The first spring 3.5 pushes the push plate 3.4 to keep the push rod 3.3 moving towards the second slot 3.1. When the connector 3 is separated from the card holder 2, the nozzle 1 approaches the connector 3, and the overall length of the connector 3 is reduced. When the connector 3 is inserted into the card holder 2, the card holder 2 pushes the push plate 3.4 to push the push rod 3.3 out of the second slot 3.1, and the nozzle 1 approaches the box girder, reducing the spray distance and increasing the spray effect.

[0022] A rubber pad 3.2 is provided on the side wall of the second slot 3.1 of the connector 3 to prevent the connector 3 from shaking on the card holder 2 when the nozzle 1 sprays water. The ends of the rubber pads are sloped, and the ends of the rubber pads 3.2 are also sloped to further facilitate the insertion and alignment.

[0023] The locking mechanism includes a guide rod 3.6, a second spring 3.7, and a limiting block 3.8. The guide rod 3.6 is disposed in the recess of the connector 3, and a slider is slidably sleeved on the guide rod 3.6. The limiting block 3.8 is fixedly connected to the slider. The second spring 3.7 is sleeved on the guide rod 3.6 and is used to push the slider, causing the limiting block 3.8 to extend from the connector 3. The limiting block 3.8 can be locked onto the retaining seat 2 to prevent the connector 3 from falling off. The collision point between the retaining seat 2 and the limiting block 3.8 is rounded. When the connector 3 is inserted into the retaining seat 2, the retaining seat 2 presses against the limiting block 3.8, pushing the limiting block 3.8 away. The limiting block 3.8 is provided with a gripping groove.

[0024] The locking mechanism can automatically lock in the slot of the card holder after insertion, preventing the nozzle from loosening or falling off during spraying; at the same time, the limit block is equipped with a gripping groove, which facilitates manual unlocking, making insertion and removal labor-saving and efficient.
