Steel wire breakage detection trolley for prestressed steel cylinder concrete pipe

Abstract

The invention discloses a steel wire breakage detection trolley for a prestressed steel cylinder concrete pipe. The steel wire breakage detection trolley for the prestressed steel cylinder concrete pipecomprises a main body support, a fixing rod, a first roller device, a second roller device, a third roller device, telescopic supporting arms, a transmitting probe array, a receiving probe array, amain control computer and a detection control circuit, wherein the main body support is in an isosceles triangle shape; two ends of the fixing rod are provided with horizontal clamping grooves; the second roller device and the third roller device are respectively arranged on the horizontal clamping grooves at the two ends of the fixing rod; the two telescopic supporting arms are respectively arranged on the horizontal clamping grooves at the two ends of the fixing rod; the transmitting probe array and the receiving probe array are respectively fixed on the two telescopic supporting arms; the main control computer is electrically connected with the detection control circuit; and the detection control circuit is respectively electrically connected with the transmitting probe array and the receiving probe array. According to the steel wire breakage detection trolley for the prestressed steel cylinder concrete pipe, the detection efficiency of steel wire breakage of the prestressed steel cylinder concrete pipe is improved.

Description

technical field [0001] The invention belongs to the field of detection of broken steel wires of prestressed steel cylinder concrete pipes, and in particular relates to a trolley for detecting broken steel wires of prestressed steel cylinder concrete pipes. Background technique [0002] Prestressed steel cylinder concrete pipe structure such as figure 1 As shown, there are five layers of structure from inside to outside, which are concrete layer, steel cylinder layer, concrete layer, steel wire layer and mortar layer. Explosion accidents of prestressed steel tubular concrete pipes are mostly due to the corrosion of steel bars and subsequent fractures of hoop prestressed steel wires under the long-term action of various factors in the service environment, resulting in a decrease in the compressive strength of the pipe wall until the pipe bursts. The number of broken wires and the approximate location of broken wires in prestressed steel cylinder concrete pipes can be detected...
