Base fixing device for mining equipment

Abstract

The invention discloses a base fixing device for mining equipment which uses the gravity of the mining equipment itself for installation and fixing, the fixing and clamping are more stable, and at the same time, the counterweight damping ball can be used to relieve the vibration force in the vertical direction of the large mining equipment. The base fixing device cooperates with the guide sleeve structure to buffer the vibration force in the horizontal direction. On the fixed ring, a plurality of the steel ropes cooperate to form a steel rope net, and the damping ball is placed in the steel rope net, and a plurality of damping springs are arranged on the outer wall of the protective shell, and the damping springs are set There is a mounting seat, the bottom of the fixed seat is equiangularly provided with a plurality of fixed sliding bars, the guide sleeve is correspondingly placed on the fixed sliding bars, and the two sides of the fixed sliding bars are provided with support plates.

Description

technical field [0001] The invention relates to a base fixing device for mining equipment, which relates to a device capable of fixing the base of mining equipment, and belongs to the field of coal mine equipment. In particular, it relates to a mining equipment that uses its own gravity to install and fix, and the fixed clamping is more stable. At the same time, the counterweight damping ball can be used to relieve the vibration force in the vertical direction of large mining equipment, and cooperate with the guide sleeve structure to reduce vibration in the horizontal direction.

AI Technical Summary

Problems solved by technology

[0002] At present, most of the mining equipment used in coal mines are electromechanical equipment with high-power output, and the equipment itself will generate severe vibration along with its high-power operation, while the existing fixing devices for the base of mining equipment are mostly Using a shock-absorbing spring or an elastic shock-absorbing mechanism for shock absorption, the shock-absorbing force is single, and the vibration transmitted by the equipment is poorly relieved, causing the vibration of the equipment to be transmitted to the ground, causing cracks, depressions, and unevenness on the ground for a long time. It will greatly affect the stability of the equipment during operation, and even cause the equipment to overturn in serious cases. Moreover, the cushioning force of a single shock-absorbing structure is small. For large-scale and high-power equipment, it is often necessary to prepare a variety of shock-absorbing structures for shock absorption to meet its shock absorption. Vibration energy demand

[0003] Notification number CN210600722U discloses a kind of damping base for coal mine excavation construction, including: placement plate, support plate, first damping spring, clamping and positioning device and other structures. The fixed damping effect of the fixed equipment is poor, and it cannot effectively dampen the vibration kinetic energy of large equipment

[0004] Notification number CN211009706U discloses a shock absorbing device for a base of a coal mining machine, including a base, a device housing and a fixing plate. The top of the base is fixed with a device housing, and a fixing plate is installed above the device housing. It can buffer the vibration force in the vertical direction of the equipment, but cannot buffer and discharge the vibration force in various directions in the multi-horizontal direction
