Escape protective net of excavator, escape method and excavator

Abstract

The invention discloses an escape protective net of an excavator, an escape method and the excavator. The escape protective net comprises a fixed support, a rotary protective net body, a sliding protective net body and a locking mechanism; the fixed support is installed on a front windshield of the excavator; the bottom of the rotary protective net body is hinged to the fixed support, so that the rotary protective net body can rotate around the fixed support; the side part of the sliding protective net body is slidably connected to the side part of the rotary protective net body; the locking mechanism is mounted at the top of the sliding protective net body; after the locking mechanism is connected with the fixed support, the rotary protective net body and the sliding protective net body are limited in the fixed support and used for preventing foreign objects from hitting the front windshield; and after the locking mechanism is separated from the fixed support, the rotary protective net body and the sliding protective net body are pushed outwards, the rotary protective net body drives the sliding protective net body to rotate outwards, and after the rotary protective net body rotates to a horizontal position, the sliding protective net body extends under the action of gravity to form an escape ladder for a driver to escape. The escape protective net is simple in structure, high in reliability and suitable for mining excavators.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to an escape protection net for an excavator. Background technique [0002] Now the working conditions of mining excavators are relatively bad. In order to effectively protect the driver from being injured by the cracked ore, a protective net will be designed at the front windshield of the cab to resist the damage of the cracked ore. In landslides or other emergencies, it is necessary to escape from the cab of the excavator, usually through the cab door or the rear window of the cab, but the mining excavator is large in size, the site is relatively high from the ground, and it is performing excavation operations. During the process, there is a high probability that the outside of the cab door is not above the track. At this time, jumping directly from the cab door is not conducive to escape, because when it is necessary to escape from the mining excavator, the place where the mining ...

Problems solved by technology

[0002] Now the working conditions of mining excavators are relatively bad. In order to effectively protect the driver from being injured by the cracked ore, a protective net will be designed at the front windshield of the cab to resist the damage of the cracked ore. In landslides or other emergencies, it is necessary to escape from the cab of the excavator, usually through the cab door or the rear window of the cab, but the mining excavator is large in size, the site is relatively high from the ground, and it is performing excavation operations. During the process, there is a high probability that the outside of the cab door is not above the track. At this time, jumping directly from the cab door is not conducive to escape, because when it is necessary to escape from the mining excavator, the place where the mining excavator is usually located It is a rocky road, and jumping directly from the car is easy to sprain your feet, which is not conducive to quickly evacuating from the dangerous area

Moreover, the rear window of the cab is small, and it will take longer to escape from the rear window of the cab, and there is no suitable escape ladder after going out from the rear window, and you will also face the problem of sprained feet.
