The invention relates to the field of bridge concrete barrier overhauling device and in particular relates to an automatic flaw detection device for cracks of a bridge concrete barrier. The automaticflaw detection device comprises two guide structures, a first driving structure, flaw detection structures, a second driving structure, a third driving structure, a push rod, a supporting frame, a fixing structure and a sliding structure, wherein the sliding structure is arranged at the bottom end of the supporting frame; the supporting frame is provided with the fixing structure for clamping a barrier; the supporting frame is provided with the third driving structure for driving the fixing structure; the supporting frame is provided with the two guide structures which are symmetrically arranged; the guide structures are connected to the second driving structure; each guide structure internally provided with the flaw detection structure which is in sliding connection; each flaw detection structure is connected to the first driving structure connected onto the supporting frame. According to the automatic flaw detection device provided by the invention, the two guide structures which aresymmetrically arranged are arranged at two ends of the supporting frame; the guide structures are provided with the flaw detection structures which are connected through the first driving structure,so that the first driving structure is used for driving the flaw detection structures to carry out flaw detection on the concrete barrier in all directions.

The invention discloses an ultrasonic flaw detection system used for a pipeline. The system includes a base seat. A through hole is formed on the base seat. Riser plates are fixedly mounted on an inner wall of one side of the through hole. Sliding holes are formed on the riser plates. A carrier block is mounted in the sliding holes in a sliding manner. One side of the carrier block extends to theoutside of a riser plate. A mounting seat is fixedly mounted on the one side of the carrier block, and is located above the base seat. A mounting hole is formed on the mounting seat. An ultrasonic flaw detector is mounted in the mounting hole. A plurality of mounting blocks are fixedly mounted at the bottom of the mounting seat. A pushing block is mounted at the bottom of each mounting block. A probe is mounted on one side of the pushing block. According to the system, adjustment on a position of the probe is facilitated, flipping of the probe is also facilitated, flaw detection on pipelines which are laid underground and erected in the air is facilitated, time and effort are saved, disassembly on the ultrasonic flaw detector is facilitated at the same time, maintenance is facilitated whena fault occurs, a structure is simple, and use is convenient.

The invention relates to a composite silicate high viscosity hot and cold smear insulation slurry, which is prepared by the following materials mixed with water and comprises: expanded perlite 4 to 9 percent by weight, diatomite 2.8 to 6 percent by weight, hill cork 1.2 to 2.6 percent by weight, bentonite 3 to 6.5 percent by weight, alumina fiber 1 to 2.5 percent by weight, glass fiber 1 to 2.5 percent by weight, alumino-silicate fiber 1 to 2.5 percent by weight, vermiculite 0.5 to 1.3 percent by weight, polyvinyl alcohol 1.2 to 2.6 percent by weight, sodium silicate solution 0 to 0.2 percentby weight, and marginal water. The slurry is compounded by the above components, the inner part of the material forms a plurality of closed micropores, and the density is reduced obviously; the micropores are filled with static air having weaker heat conductive property, which can restrain the transmission of external heat effectively. The composite silicate high viscosity hot and cold smear insulation slurry has the advantages of light weight, low thermal conductivity, obvious heat preservation, insulation and deafening effect, high tensile strength, water and oil resistance, wide applied temperature scope and high bond force.

The invention discloses pump part machining and flaw detection equipment. The pump part machining and flaw detection equipment comprises a machine base, universal wheels and a machining and a flaw detection box body, wherein the inner cavity of the machining and flaw detection box body is divided into a left side machining chamber and a right side cleaning and flaw detection chamber through a partition plate, a first supporting plate is arranged in the middle of the left side machining chamber cavity, a pump part intelligent machining device is arranged at the upper end of the first supportingplate, a feeding mechanism is arranged at the lower end of the left side machining chamber cavity, the feeding mechanism is composed of first screw rods, feeding plates, a worm and worm wheels, the right side cleaning and flaw detection chamber is provided with a second supporting plate, a cleaning and flaw detection assembly, a water collecting tank and a belt conveyor, and the cleaning and flawdetection assembly is composed of a disc shaped placing frame, an air cylinder, a pressing plate, an arc-shaped groove, an arc-shaped seat, a second screw rod, a sliding seat, a water spraying head,a drying head, an ultrasonic flaw detector and a transmission assembly.

The invention relates to a cleaning process for bearing repairing. The cleaning process comprises the following steps: a bearing is disassembled into single parts, and the single parts are placed on acommodity shelf in classified and layered modes; the commodity shelf is hoisted into a degreasing cleaning pool to degrease the bearing parts; the degreased bearing parts and the commodity shelf aresubjected to still standing, and a rust remover is sprayed on the surfaces of the bearing parts; the rust remover and rust stains on the surfaces of the bearing parts and the commodity shelf are rinsed off with clear water, and the bearing parts and the commodity shelf are dried; appearance flaw detection is conducted firstly through manual work, then internal flaw detection is conducted through aflaw detector, and the bearing parts with repairing value are screened to enter into the next procedure; and the bearing parts are immersed into rust-proof liquid to be subjected to rust-proof treatment, and after being taken out, the bearing parts are subjected to a bearing repairing process of the next step. According to the cleaning process and equipment, equipment for bearing cleaning can bereduced, the cleaning step is simplified, and the cleaning efficiency and the repairing efficiency of the bearing are improved.
