Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of underground shovel loader, in particular to a connecting device of a cab roof of an underground shovel loader. BACKGROUND

[0002] The underground shovel loader is a loading, transporting and unloading equipment with a diesel engine or a motor powered by a towed cable as a prime mover, a hydraulic or hydrodynamic mechanical transmission, an articulated frame, a tire walking, a front-end front-dumping bucket, mainly used in underground mines and tunnel engineering.

[0003] As an important part of the cab, the roof needs to rely on the frame to provide stable support. The underground shovel loader will face various complex working conditions and road conditions during the working process, generating relatively large vibration and impact. By connecting the roof and the frame, the roof can transmit these external forces to the frame, which is borne and dispersed by the frame as a whole, thereby ensuring the integrity and stability of the roof structure, preventing the roof from deforming, damaging or even falling off due to vibration and impact, and providing a safe working space for the driver.

[0004] In the prior art, the common connection methods of the cab roof and the frame are welding or connecting through a pin shaft. When welding, the upper end of the frame side plate and the roof are firmly connected together through the welding process. The welding method makes the roof and the frame have high connection strength, which can withstand large external forces and vibrations. However, when the roof or the frame needs to be repaired or replaced later, the disassembly of the welding part is relatively difficult. The pin shaft connection can make the roof have a certain degree of rotational freedom relative to the frame. However, the pin shaft connection mainly relies on the pin shaft to transmit force and torque, and the shear force and tensile force it can withstand are usually relatively small. Long-term use can easily cause the pin shaft to wear, thereby affecting the connection strength. Therefore, it is urgent to provide a connecting device that is easy to disassemble and has high connection strength. CONTENT OF THE UTILITY MODEL
