New Design about Crane Rail Flat Bar Inspection Device


New Design about Crane Rail Flat Bar Inspection Device
Crane rail flat bar detection requires the detector to be as smooth as possible to reduce vibration and shaking during operation. The overall center of gravity should be as close as possible to the top of the crane rail flat bar and near the center axis of the crane rail flat bar to keep the unit stable. The target of the reflective target should be as close as possible to the center line of the top surface of the crane rail flat bar and ensure that the light is not blocked by itself when measuring. The crane rail flat bar clamping device of the instrument clamps the side of the rail through the guide wheel to maintain the running posture, and a spring urging mechanism is used to maintain the tension of the guide wheel to facilitate the passage of the rail joint and the unevenness of the side of the rail. The detector components are mainly designed with positioning components, clamping components, proximity switches, front wheel components, drive components, circuit board brackets, rear wheel components, trays, frames, reflective target lifting rods, reflective target bases, reflective targets, etc. One side of the instrument is a positioning component, which is used to ensure the running direction of the rail along the rail direction, and to ensure that the center line of its shape coincides with the center line of the top surface of the rail. The positioning arm is in contact with the inclined side of the rail 1:10, and the joint bearing is used as the contact part, and the contact has become the surface contact, which ensures the positioning and clamping clarity.
The other side of the instrument is a clamping part. The joint bearing seat and the positioning arm are connected by springs and bolts, mainly for the purpose of ensuring that the positioning parts are not stuck during operation under the premise of packaging positioning accuracy. During the installation process of the rail, the two clamping members and the two positioning members can be rotated 180° about the fixed axis to the rail face to clamp the side of the track to clamp the track. Both the clamping part and the positioning part are equipped with anti-rollover arms, which can be twisted around the rotating shaft under the action of the torsion spring. When an obstacle is encountered, the rollover arm can be rotated to avoid the obstacle. When the device is turned over in an unexpected situation, the anti-rollover arm can hold the track tightly to ensure safety and reliability. The reflective target lifting rod can adjust the elongation distance of the reflective target to ensure that the measured light is not blocked by the instrument itself at different orbital heights.

Welding Process of Overhead Crane Rail Joint

Welding Process of Overhead Crane Rail Joint In order to make the overhead crane rail transport more stable, rail splints will not be used for the overhead crane rail joint connection, but welded joint connection will be used. The main key to the welded joint is to solve the bending deformation and weld cracking of the overhead crane rail joint. During the welding process of the overhead crane rail joint, the overhead crane rail joint is deformed downwardly, so the overhead crane rail end must be padded to a certain height before welding to ensure that the rail joint can be kept straight after the welding is completed. The height of the rail end pad is determined by factors such as the type of rail, length, fixing method and ambient temperature. The rails are fixed to the crane beam by means of hook bolts, and each joint is provided with four fixed points. After the bottom of the rail is welded, reduce the height to 20mm, and then tighten the hook bolts to continue welding. When the o...

Study on the Influence of 40×60 Crane Rail Plate Stres

Study on the Influence of 40×60 Crane Rail Plate Stress The main operation mode of the overhead crane is the orbital operation, that is, the wheel supports the whole crane and transmits the gravity to the lower 40×60 crane rail , and the 40×60 crane rail receives the concentrated pressure from the crane wheel and guides the wheel to run. Therefore, the track device is the direct load-bearing structure of the crane device. Usually, special rails that meet the requirements of the wheels are used as crane rails. These rails are fixed with the pressure plate and the structure of the plant. If the crane runs at a slow speed, the operating frequency is not high, and the wheel pressure is not large, this solution can still meet the requirements. However, if the crane is in a high-speed, frequent or large-wheel working environment, the existing fixing method cannot meet the performance requirements. At this time, the phenomenon that the rail press plate bolt is broken is extremely likely to ...
