Technical Field

The invention relates to the technical field of belt conveyors, in particular to a belt conveyor provided with a driving part balance adjusting device.

Background

The belt conveyor transport system is the most important bulk cargo transport system at present, and has wide application in both underground mines and strip mines.

In recent years, with the progress of open-pit mining technology in China, newly-built open-pit mines in China are more and larger in scale, and the displacement and semi-displacement belt conveyor replaces the original automobile transportation system to become main transportation equipment of the open-pit mine, and is throat equipment in both a soil layer stripping system and a material mining system, which can be called as huge!

Because of the particularity of the working condition of the strip mine, the whole belt conveyor is not fixed on the basis regardless of displacement or semi-displacement, and only fixed by adopting the anchoring devices at the head station and the tail station, the ground for mounting the conveyor is not hardened, so that the driving part of the conveyor cannot be fixed on the ground like the driving part of a conventional conveyor, and only fixed on the head station or the tail station, and the driving part base cannot be integrally fixed due to limited space of the head station and the tail station, only one end of the driving part base can be fixedly connected with the transmission roller shaft by using the output shaft of the reducer, and the other end of the driving part base is supported on the supporting beam by adopting a single-point floating type hinging device. Therefore, the hinge device at the supporting position becomes very important, and the common hinge device only adopts a simple pin shaft and a bearing bush to be matched for use, so that the degree of freedom at the hinge point is limited to be too much, and the deformation of the driving part caused by external factors cannot be released, and finally the bearing bush of the hinge device is damaged, the pin shaft is broken, or the axial additional force borne by the shaft head of the transmission roller is too large, so that the service life of the bearing of the transmission roller is influenced.

In the prior art, the driving part is radially arranged in two modes, the first mode is that the driving part is directly fixed on the supporting beam or the ground, the driving part is fixedly connected with the ground or the supporting beam in the mode, relative displacement or buffering between the driving part and the ground cannot be realized, the second mode is that a sleeve structure is arranged between the bottom of the driving part and the supporting beam, and the structure can only realize displacement buffering in the vertical direction between the driving part and the ground and cannot realize buffering in other directions. Both of these methods are liable to cause damage to the driving portion. As shown in fig. 8.

Preferably, the upper hinge seat is connected with the driving part in a welding mode, and the lower hinge seat is detachably connected with the supporting beam.

Preferably, the inner ring is in transition fit with the upper pin shaft, a positioning ring is directly arranged on the inner ring and the upper connecting lug to lock and connect the inner ring and the upper pin shaft, and a positioning ring is directly arranged on the inner ring and the lower connecting lug to lock and connect the inner ring and the lower pin shaft, so that the inner ring, the upper pin shaft and the lower pin shaft are fixedly connected, and the inner ring and the upper pin shaft and the lower pin shaft are prevented from relative displacement.

Preferably, a check ring is arranged between the upper pin shaft and the outer wall of the upper connecting lug, and a check ring is arranged between the lower pin shaft and the outer wall of the lower connecting lug so as to lock and connect the inner ring and the lower pin shaft, so that the inner ring, the upper pin shaft and the lower pin shaft are fixedly connected, and the inner ring and the upper pin shaft and the lower pin shaft do not generate relative displacement.

Preferably, the end parts of the upper pin shaft and the lower pin shaft are provided with oil filling cups so as to inject lubricating grease into the universal joint.

In the invention, because the upper universal joint can bear the radial stress and the axial stress, the whole driving part can move back and forth and left and right around the fixed ends of the output shaft of the speed reducer and the shaft of the transmission roller, so that when the driving part is deformed or displaced under the influence of external factors, the deformation or the displacement can be eliminated through the displacement of the upper hinging device and the lower connecting device, and no additional force can be generated on the hinging device or the shaft head of the transmission roller, thereby ensuring the normal operation of equipment. And the characteristic can also solve the problem that the reaction torque generated by the transmission roller is too large to bring influence to the output shaft of the speed reducer when the conveyor is started under heavy load or is subjected to impact load in the running process.

The invention has the beneficial effects that: the damage to the transmission roller bearing and the hinging device caused by the deformation of the driving part of the floating type hinging support adopted by the displacement and semi-displacement belt conveyor for the strip mine under the influence of external factors is effectively solved, and the service life of the bearing is prolonged. The floating type articulated support device has an obvious effect on solving the working condition that a driving part of a high-power belt conveyor adopts a floating type articulated support, solves the big problem by adopting low cost, not only improves the overall economy of the conveyor, but also provides powerful guarantee for the normal operation of the conveyor.
