Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and particularly relates to a lengthened support device for a steel cage transported by a truck crane. Background Art

[0002] This area is located in the mountainous area of ​​Guangxi, with dense mountains and poor access conditions for construction access roads. In addition, large-diameter steel cages for structures such as bridges are mostly 12m in length, which need to be transported one by one from the steel processing plant to the bridge construction site for installation. In the past, when using a truck crane for transportation, the length of the truck crane compartment generally did not meet the length requirements of the steel cage, resulting in the steel cage not only sliding during transportation due to lack of effective support, but also the steel cage length exceeding the length of the truck crane compartment is very easy to deform due to road bumps and lack of effective support during long-distance transportation. This problem seriously affects the safety and quality requirements of bridge construction.

[0003] After reviewing the existing similar auxiliary equipment for transporting steel cages, there is only one self-made transfer vehicle in the field of building construction and other construction sites that can transport steel cages over short distances. Because it does not have the transportation capacity itself, it needs to be connected to a trailer for power traction. In addition, due to its simple structure and poor stability, it cannot meet the safety requirements for long-distance transportation of steel cages for linear engineering construction such as highways. In view of the actual situation of on-site construction of linear engineering such as highways, a truck crane with self-unloading capacity and good construction access road traffic capacity is still the first choice for long-distance transportation of steel cages for linear engineering construction such as highways. In the case that it is impossible to increase the length of the truck crane used to transport the steel cage, it is necessary to develop a telescopic extension support device to cooperate with truck cranes and other transportation tools to ensure that the steel cage will not be deformed during long-distance transportation due to road bumps and lack of effective support. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to solve the problem of long-distance transportation of steel cages used in the construction of linear projects such as highways. It not only avoids the risk of the steel cages slipping during transportation, but also greatly ensures that the steel cages will not be deformed due to road bumps and lack of effective support, thereby ensuring the quality requirements of bridge structure construction.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a lengthened support device for transporting a steel cage with a truck crane, characterized in that it includes a bracket, a telescopic rod, a hydraulic rod, and a mounting connector; the bracket includes a cross brace, a column, and an arc bracket, the midpoint of the cross brace is connected to the end of the telescopic rod, the column is vertically connected to the two ends of the cross brace, and the upper ends of the columns are connected through arc brackets; the telescopic rod has a built-in hydraulic cylinder that utilizes the truck crane's own hydraulic oil pipe to extend and retract, and the front end of the telescopic rod is connected to the bottom beam of the truck crane's car body through a mounting connector; the hydraulic rod is fixed between the telescopic rod and the mounting connector.

[0006] The cross brace is made of 2000mm long 10# square steel pipe, the column is made of 600mm~800mm long 10# channel steel, and the arc support is made of round steel. The cross brace and the column are connected by welding and bolts. The central angle of the arc support is 120°~180°.

[0007] The telescopic rod is made of square steel pipe, and its length is appropriately adjusted according to the length of the transport steel cage.

[0008] The hydraulic rod is a cylinder with a stroke of 1504mm, which is lifted by the hydraulic oil pipe of the truck crane itself to achieve the purpose of controlling the extension support device to adjust the telescopic length.

[0009] The installation connecting parts include a cross bar and a connecting steel plate. The cross bar is made of 10# square steel pipe, and both ends are welded and connected to the bottom beam of the truck crane compartment. The cutting length is determined according to the spacing of the bottom beams of the truck crane compartment. The cross bar is connected to the telescopic rod by a connecting steel plate with a thickness of 20 mm.

[0010] The utility model aims at transporting steel cages for construction of structures such as bridges in linear projects such as highways. The extended support device is installed on the basis of existing transport tools such as truck cranes with built-in hydraulic oil pipes, and the hydraulic oil pipes of the truck cranes themselves are used to extend and retract the telescopic rods and hydraulic rods of the support device, so as to achieve the purpose of controlling the extended support device to adjust the telescopic length and angle, so that the bracket provides auxiliary support for the steel cage that exceeds the length of the car body, which not only avoids the risk of the steel cage sliding during transportation, but also greatly ensures that the steel cage will not be deformed due to lack of effective support during long-distance transportation, thereby ensuring the construction quality requirements.

[0011] The utility model is easy to install and, in order to meet its economic efficiency, is particularly suitable for transport vehicles with built-in hydraulic oil systems such as truck cranes. It is extended and retracted through hydraulic jacks to adapt to the length of the transported steel cage and can be fully retracted under the carriage when not in use, without affecting the vehicle's transportation function for other types of goods.
