Description

Technical Field

[0001] The utility model belongs to the technical field of box-type culverts and relates to a construction hanging device for an assembled box culvert. Background Art

[0002] A box culvert is a culvert whose body is constructed with reinforced concrete box-shaped pipe sections. It is often used in drainage locations. As a high-strength and easy-to-manufacture drainage tool, it is an important water conservancy tool in rural suburbs of my country. Made of concrete and steel bars, box culverts have high structural strength, long service life and large load-bearing capacity. At the same time, the size of the box culvert can be changed by simply changing the position of the steel bars to meet different drainage requirements. In the existing technology, culverts are a relatively large component of railways, highways, and municipal engineering, and the design and construction technology is relatively mature. At present, box culvert devices have become the preferred solution for large-span water crossings or traffic culverts. Compared with pipe culverts, arch culverts and other forms, they have a wide range of applications, a larger span, and good force-bearing performance. In recent years, prefabricated and assembled concrete box culverts have been used more and more in China. Prefabricated prefabricated box culverts are a kind of box-shaped structure prefabricated with reinforced concrete. It is a rapid construction process for box culverts. It mainly adopts centralized prefabrication on site and can be prefabricated in advance in the factory. It has a fast production speed and the construction quality is easy to control. It has fast mechanical transportation and on-site assembly construction speed, which can effectively shorten the construction period. It has the advantages of easy control of construction quality, short construction period and high construction efficiency.

[0003] In the traditional construction of prefabricated box culverts, cranes are usually used for lifting. This method requires a lot of manpower and material resources, and has low construction efficiency and poor safety. In addition, due to the complex construction site environment, cranes are difficult to adapt to various terrains and environments, which limits their application in some special occasions. Utility Model Content

[0004] The utility model aims to solve the technical problems of low construction efficiency and poor safety of the hoisting method of the assembled box culvert in the prior art, and to provide a construction hoisting device for the assembled box culvert.

[0007] The further improvement of the utility model is:

[0008] The support groove is made of metal.

[0009] The movable support device is an L-shaped structure, one side of the L-shaped structure is slidably connected in the groove of the support groove, and the other side is parallel to the top of the support groove, and is used to place the support legs of the assembled box culvert.

[0010] A plurality of rollers are arranged on the sliding matching surfaces of the L-shaped structure and the groove of the supporting groove.

[0011] A groove is arranged on the sliding matching surface between the L-shaped structure and the groove of the supporting groove, and a plurality of rollers are arranged in the groove, and the rollers are in contact with the bottom surface of the groove of the supporting groove.

[0012] The widths of the support groove and the movable support device are both smaller than the width of the support legs of the assembled box culvert.

[0013] It also includes an infrared sensor which is arranged on the wall surface of the groove for placing the conveying device during operation; the infrared sensor and the traction device are both connected to a controller.

[0014] The lifting height of the lifting device is greater than the total height of the assembled box culvert.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model discloses a construction hanging device for an assembled box culvert. Two ground trenches with a width smaller than the width of the legs are dug at the positions where the legs on both sides of the assembled box culvert are to be set. Then, a middle ground trench with a width capable of placing 2-3 construction hanging devices is dug at the position between the two ground trenches. A corresponding number of construction hanging devices are arranged in the ground trench. During construction, the lifting device rises so that the movable support device of the construction hanging device is exposed from the ground trench. The legs are placed on the movable support device. The traction device pulls the legs to the installation position. The lifting device descends so that the legs are placed on the ground. The legs are integrated with the side wall. After the legs on both sides are installed, the top plate is placed on the movable support device of the construction hanging device in the middle ground trench. The lifting device is lifted to a suitable position and the top plate is installed on the side wall. Compared with traditional lifting equipment, the utility model can accurately position the box culvert, construct the assembled box culvert through a liftable conveying device, improve safety, and reduce the impact on the environment. The device has a simple structure, is easy to operate, and has strong adaptability. It can be used for the hanging and installation of longer box culverts. The construction method is highly efficient and does not require large lifting equipment, which can significantly reduce manpower and material costs and construction time. It has little impact on the construction site environment, can adapt to various terrains and environmental conditions, and can be used in complex terrains and environments. At the same time, through the precise control of the conveyor belt, the position accuracy and verticality of the prefabricated box culvert can be greatly improved, reducing the workload of adjustment and correction.

[0017] Furthermore, the utility model also includes an infrared sensor which is arranged on the wall surface of the groove for placing the conveying device during operation; the infrared sensor and the traction device are both connected to a controller. When the side wall is transported to the infrared sensor, the infrared rays emitted by the infrared sensor are blocked, and the infrared sensor issues a command to stop the new conveying device and move the side wall downward to a designated position, making the installation position more accurate and saving manpower.
