This utility model relates to a quick-release clamping device for a single-sided rail web grinder, comprising an inverted L-shaped main frame, a convex-edge rail wheel, a movable side top plate, a rail jaw clamping wheel, a rail clamping top clip, a moving handle, a fixed handle, a T-shaped vertical sliding plate, a pneumatic support rod, an electric grinder main unit, a shock absorber, and a force-relieving lateral pull handle. The quick-release clamping device designed in this utility model adopts a balanced fixing method with two-point support on one side for rail clamping and downward pressure on the opposite side's center of gravity. The main frame of the clamping device is made of lightweight metal alloy, and the clamping device structure is extremely simple and lightweight. By pressing down on one side of the handle, the rail is clamped and locked, while on the other side, the grinding wheel presses firmly against the rail, and the device is fixed by the natural downward pressure of the center of gravity. This quick-release clamping device has an ingenious structural design, is easy to install and disassemble, and is simple to operate. It can quickly fix the rail web grinder to or remove it from the rail, effectively reducing on-site construction labor intensity and improving work efficiency.

The application discloses a wheel type red light connection early warning guide wheel device for a rail flaw detector, which comprises a device main body, the device main body is used for detachable connection with a double-track rail flaw detector, two groups of symmetrical conductive rail running wheels are arranged on the device main body, the two groups of conductive rail running wheels are respectively corresponding to two rails of the double-track rail flaw detector, and the conductive rail running wheels are made of conductive materials. The wheel type red light connection early warning guide wheel device for the rail flaw detector utilizes the original track circuit of a railway, controls the on-off of switches to make the two-side rails short-circuit, triggers a signal system "red light belt", realizes automatic and real-time early warning of an operation position, does not need manual additional protection, and can flexibly control the start and stop of the red light connection function according to operation requirements, and has compact structure, strong adaptability and greatly improved safety and operation efficiency of rail flaw detection operation.

The hook device for the side beam of the chassis belongs to the field of the lifting hook device of the chassis of the railway vehicle, comprising a sling shackle mechanism and a steel wire sling, the shackle mechanism comprising a shackle and a shackle connecting rod connected with each other in the rotation shaft, and the end section of the steel wire sling is suspended and linked with the shackle ring of the shackle; the hook device further comprises an outer hook, a rotation shaft bolt, a plurality of bolt fasteners, an inner hook, an inner pad, and an outer pad, the lower parts of the outer hook and the inner hook are fixedly connected through the plurality of bolt fasteners; the upper end of the outer side of the outer hook is rotationally connected with the lower end of the shackle connecting rod through the rotation shaft bolt; the outer pad is fixedly connected on the vertical inner end face of the outer hook in a detachable manner, and the inner pad is fixedly connected on the vertical outer end face of the inner hook in a detachable manner. The present application can reliably clamp and horizontally hoist the frame of the four corners of the chassis of any straight side beam or inclined side beam with any inclination angle and size parameters.

The utility model relates to a railway wagon loading state detection system based on 2D3D fusion belongs to the field of track vehicle three -dimensional imaging, solves the problem that the existing railway vehicle state monitoring system causes the problem that the measurement precision is influenced greatly based on image automatic identification, three multi -line laser radars of the utility model are installed to the top of truss and left and right side surface, and the controller is installed at the bottom of truss, one magnetic steel speed sensor is set in the direction of coming train of truss according to preset distance, and is fixed outside one side rail, and the remaining two magnetic steel speed sensors are set in the direction of leaving train of truss, and are set outside the same side rail, and there is interval between the two, and the controller carries out coordinate transformation, fusion, superposition and splicing according to three multi -line laser radars gathering three -dimensional point cloud data in proper order, and then combines speed information, restores three -dimensional point cloud image of whole railway wagon, extracts the profile size of goods in each compartment in the image, realizes loading state monitoring, and is mainly used for wagon loading state monitoring.
