Description

Technical Field

[0001] This utility model relates to the field of track welding technology, specifically to an intelligent detection device for track weld seams used in track fault diagnosis. Background Technology

[0002] Because of its unique supporting function, the rail is made of steel with compressive and shock resistance. Since the rail changes length as the journey progresses, welding machines are needed to weld the joints during assembly. To prevent the welds from cracking or misaligning, testing devices are required to test the welds.

[0003] Traditional inspection methods require applying developing agents to the surface of the object before taking a picture. When processing the negative of the photograph, the silver ions can be revealed during the light exposure, and the shape of the gap can be clearly shown on the film. However, such institutions often require manual assistance and are difficult to move automatically to the required position, which is labor-intensive and time-consuming.

[0004] Now, a novel intelligent detection device for track welds used in track fault diagnosis is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent detection device for track welds for track fault diagnosis, so as to solve the problem of the inconvenience of moving the device mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent detection device for track welds for track fault diagnosis, comprising a base plate and a rail. A rail is provided on the left side of the base plate, a base is fixed on the top of the base plate, electric wheels are installed at the four corners of the bottom of the base plate, a housing is installed on the top of the base plate, and a tube is welded to the front and rear ends of the left side of the housing. A movable chamber is provided between the two sides inside the tube, and a lead screw is horizontally assembled in the movable chamber. Threaded blocks are sleeved on both sides of the lead screw. A lifting rod is welded to the bottom of the threaded block, and a guide wheel is movably connected to the bottom of the lifting rod.

[0007] Preferably, the guide wheel is attached to both sides of the rail, and the guide wheel can rotate horizontally on both sides of the rail.

[0008] Preferably, the tube is attached to the top of the rail, and the tube is symmetrically distributed at the front and rear ends on the left side of the base.

[0009] Preferably, a sliding groove is provided between the upper and lower parts of the left side inside the housing, and a motor is installed above the sliding groove. A screw is assembled between the upper and lower parts of the inner side of the sliding groove. A sliding sleeve is sleeved on the outside of the screw, and a crossbar is welded to the left side of the sliding sleeve. A short tube is fixed longitudinally inside the crossbar, and a limit block is fixed at the top of the short tube. A diverter tube is welded to the bottom of the short tube, and a spraying plate is installed laterally at the bottom of the diverter tube. A camera is installed at the center of the spraying plate.

[0010] Preferably, the bottom shaft of the motor is fixedly connected to the screw, and the screw and the sliding sleeve are arranged in concentric circles.

[0011] Preferably, the crossbar can be vertically raised and lowered with the sliding sleeve, and the crossbar passes through the left side inside the sliding groove.

[0012] Preferably, a liquid pump is installed at the center of the top of the housing, and a water pipe is fixed between the output end of the liquid pump and the limiting block. A display screen is installed on the right side of the exterior of the housing, a suction tube is fixed at the bottom of the output end of the liquid pump, and a liquid tank is provided on the right side of the interior of the housing.

[0013] Preferably, the water pipe is connected between the liquid pump and the limiting block, and the bottom of the suction tube is embedded in the liquid tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the intelligent detection device for track weld seams for track fault diagnosis not only realizes the automatic sliding of the device and the adjustment of the spraying and shooting height, but also realizes the automatic application of developing agent;

[0015] (1) By welding tubes to the front and rear ends of the outer left side of the housing, the base plate with electric wheels is moved horizontally so that the two tubes on the left side are attached to the top of the rail. Then the left side of the screw is rotated so that the threaded blocks sleeved on both sides of the screw slide along the inner wall of the movable cavity. Under the connection of the hanger, the guide wheel is forced to be attached to both sides of the rail. When the electric wheel is started, it is attached to the main body of the rail moving device on the left side, which facilitates automatic application of developing solution and taking pictures at the weld of the rail.

[0016] (2) By installing a spray plate horizontally at the bottom of the shunt pipe, when the right-side display screen shows the spray plate moving to the weld seam through the camera, the top motor can be turned on and the slide sleeve and crossbar can be raised and lowered vertically in the lower slide groove to adjust the height of the shunt pipe and the bottom spray plate and attach it to the top of the weld seam. The developing liquid is sprayed out from the nozzles on both sides and then the camera is used to take pictures for observation of the shape of the weld seam, so as to avoid the developing liquid flowing to other places and causing pollution.

[0017] (3) By setting a liquid tank on the right side inside the housing, the housing at the top of the base stores the developer through the liquid tank on the right side. The bottom of the liquid pump is inserted into the liquid tank by means of a suction tube. After the liquid pump is turned on, it can be drawn through the water pipe and flow through the limiting block and short pipe into the diversion pipe, and discharged through the nozzles on both sides of the bottom. Even if the developer is used up, it can be replenished in time without the need to replenish the material from elsewhere. Attached Figure Description
