Description

Technical Field

[0001] The invention relates to a locomotive control panel connection technology, in particular to a concealed connection method for a locomotive control panel panel. Background Art

[0002] With the rapid development of my country's railways, various types of locomotives have been rapidly improved. The locomotive cab is equipped with various types of main control electrical appliances that control the operation of the train, especially the locomotive control panel is equipped with driver controllers, levers, computer screens, buttons and other main switch electrical appliances that control the operation and braking of the locomotive. Taking into account the reasons of later maintenance, the locomotive control panel is generally installed with the control panel frame by screw live connection. At the same time, the lower part of the control panel is connected to the locomotive frame, and the control panel is matched with the outline of the driver's cab steel structure. Because the steel structure of the locomotive driver's cab is a gradual arc, the cross-sectional dimensions of the outline of the steel structure of the driver's cab at different heights are different. If the control panel is aligned with the mounting hole of the control panel frame, there is a problem of uneven matching gap between the control panel and the steel structure of the driver's cab, and the front and back and left and right cannot be adjusted at the same time. If the matching gap between the control panel and the steel structure of the driver's cab is adjusted evenly, there is a problem that the control panel and the frame mounting holes are not easy to align. In addition, the control panel and the control panel frame are directly connected with screws, which has a small adjustment range and is troublesome to install. When the panel needs to be removed for subsequent electrical maintenance, the instrument panel electrical appliances need to be removed to remove the internal connection screws, which makes maintenance difficult. If the connection screws are exposed, although it is easy to disassemble, it affects the overall appearance of the control panel. Summary of the invention

[0003] The purpose of the present invention is to provide a concealed connection method for a locomotive control panel. The control panel can be adjusted forward and backward and left and right without being restricted by the structural form. In particular, the control panel can be infinitely adjusted in the left and right directions with a large adjustment range. At the same time, the front of the control panel adopts a snap-on structure. When installing, the panel is directly pushed into place, and the snap-on spring can firmly fix the front of the panel. After the control panel is installed in place, the panel can be quickly fixed with screws only from the back of the panel (driver's seat). This method does not allow the fixing screws to leak out, and the installation and disassembly are quick and convenient, and the connection is firm and reliable. At the same time, the installation error between the control panel frame and the panel caused by the error of the locomotive steel structure can be absorbed.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is: it relates to a concealed connection method for a locomotive control panel, which is characterized by: comprising a control panel panel assembly, a snap assembly, a pressure block assembly, a control panel frame, a driver's cab steel structure and its matching gap; the control panel panel assembly comprises: a panel table, a panel folding edge, and a panel pressing edge.
