Loose detecting device for arm support bearing cap

Abstract

The invention discloses a loosening detecting device of an arm support bearing cap, belongs to the bearing protection devices of engineering crushing machines, and particularly relates to a bearing protection device of a taper crushing machine. The arm support bearing cap is connected with an arm support bearing holder, an arm support bearing is fixed inside the arm support bearing holder, and the key technical points of the bearing protection device of the taper crushing machine is that a contact position with the arm support bearing cap on the arm support bearing holder is provided with an orifice, the outer wall of the arm support bearing holder is provided with a nick that is communicated with the orifice, a proximity switch is arranged inside the orifice, and a conducting line on theproximity switch runs through the nick to be connected with a signal lamp. The bearing protection device of the taper crushing machine does not need operators to observe the loosening situation of the arm support bearing cap on the spot, but discovers the loosening and dropping situations of the arm support bearing cap in time by utilizing limit sensing techniques and alarming signals, has high alarming sensitivity, improves the observing accuracy and lowers the labor intensity of operators. The bearing protection device of the taper crushing machine solves the unsolvable problem that in a long time, the operators need to observe the loosening and dropping situations of the arm support bearing cap on the spot.

Description

technical field [0001] The utility model relates to a loose detection device for an arm frame bearing cover of a cone crusher, which belongs to a bearing protection device for an engineering crusher, and in particular relates to a protection device for an upper bearing of a cone crusher. Background technique [0002] The cone crusher is suitable for the production of artificial aggregates with a particle size of 20mm to 80mm for engineering. It mainly uses the cone to vibrate to squeeze the material with a particle size of 150mm to 200mm, and breaks the material into useful aggregates with a particle size of 20mm to 80mm. The upper part of the cone is used The arm frame bearing is fixed, the arm frame bearing is fixed in the arm frame bearing seat, the top is covered with the arm frame bearing cover, and the arm frame bearing cover is connected with the arm frame bearing seat with screws. During the operation of the crusher, materials of 150mm to 200mm hit the bearing cover ...

AI Technical Summary

Problems solved by technology

During the operation of the crusher, materials of 150mm to 200mm hit the bearing cover of the boom, which caused a large vibration of the bearing cover of the boom, causing the connecting screws to loosen and fall off, and the materials of 150mm to 200mm directly impacted the bearing of the boom, causing boom The frame bearing is damaged, so that the equipment cannot operate normally, and the economic loss cannot be underestimated

The discovery of this phenomenon during operation has been observed manually for a long time. Since the cone crusher inevitably has material splashes during operation, the observation position of personnel is far away, which is not conducive to timely detection of problems and increases the labor of operating personnel. strength

People have always wanted to solve the problem of not having to manually go to the scene to observe the looseness of the bearing cap, but they have not been able to do so
