High-safety locking device capable of achieving hydraulic crusher maintenance conveniently

Abstract

The invention provides a high-safety locking device capable of achieving hydraulic crusher maintenance conveniently. Transmission rods are fixedly mounted at the left end and the right end of a crushing roller, the rear surfaces of the transmission rods are engaged with discs, clamped connection plates are arranged on the left side and the right side of each disc, the bottom ends of the adjacent clamped connection plates are movably connected, auxiliary rods are connected to the tops of the clamped connection plates, adjusting frames are movably connected to the top ends of the auxiliary rods, and pressing columns are movably mounted at the top ends of the adjusting frames. When a machine body is maintained, after the pressing columns are extruded downwards, spring clamping blocks on the surfaces of the pressing columns are in clamped connection with the machine body, and the pressing columns drive the adjusting frames to move downwards, the adjusting frames drive the auxiliary rods to move inwards, the clamped connection plates at the bottom ends of the auxiliary rods move inwards at the same time, and therefore the adjacent clamped connection plates are driven to be engaged with tooth blocks on the surfaces of the discs to limit rotation of the discs, the discs cannot drive the transmission rods to rotate, and therefore the situation that the crushing roller rotates freely due to outside vibration and hurts personnel is avoided.

Description

technical field [0001] The invention belongs to the technical field of hydraulic breakers, and in particular relates to a high-safety locking device convenient for maintenance of hydraulic breakers. Background technique [0002] Hydraulic crusher refers to the crushing machine whose particle size is greater than 3 mm in the discharge, accounting for more than 50% of the total discharge volume. The crushing operation is often divided into coarse crushing, medium crushing and fine crushing according to the size of the feeding and discharging particles. , and when the crusher is in the maintenance room, it can still rotate under the condition of external force, which is easy to cause accidents for maintenance personnel, so a specific locking device is required for assistance. [0003] When the crusher is running, it cannot absorb the dust generated inside the machine body, and the inside will be blocked during screening, resulting in low crushing efficiency. At the same time, t...

[0002] Hydraulic crusher refers to the crushing machine whose particle size is greater than 3 mm in the discharge, accounting for more than 50% of the total discharge volume. The crushing operation is often divided into coarse crushing, medium crushing and fine crushing according to the size of the feeding and discharging particles. , and when the crusher is in the maintenance room, it can still rotate under the condition of external force, which may easily lead to accidents for maintenance personnel, so a specific locking device is required for assistance

[0003] When the crusher is running, it cannot absorb the dust generated inside the machine body, and the inside will be blocked during screening, resulting in low crushing efficiency. At the same time, the crushing roller will rotate freely due to external vibration during maintenance and cause harm to personnel. Therefore, in view of this , research and improve the existing structure and defects, and provide a high-safety locking device for hydraulic crusher maintenance, in order to achieve more practical value
