Problems solved by technology

However, due to the impact of mining and technical conditions, the pump workers, electricians and transfer machine drivers of the equipment team in the mining face cannot stop working in dangerous areas. For this reason, the management requires employees to work standing in the middle of the roadway, and it is strictly forbidden to sit. Lane side and equipment rest on materials
The following problems existed during the on-site operation: First, the impact of ground pressure during the standing period of the workers can only effectively reduce the injuries of the waist and above, but it is very easy to cause leg fractures; second, the workers are required not to sit on the ground during the eight-hour working time Breaks are unrealistic and difficult to execute

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0022] refer to Figure 1-5 , an anti-shock spring chair, comprising a chair frame, a bottom buffer mechanism 5, a back buffer mechanism 6 and a limit mechanism, a seat cushion 4 is installed on the top of the chair frame, and a backrest 1 is installed on one side of the top of the chair frame, and a welding support is installed at the bottom of the chair frame The legs 3 and the bottom buffer mechanism 5 are arranged directly below the seat cushion 4, and the back buffer mechanism 6 is arranged on one side of the backrest, and the limit mechanism is arranged at the center of one side of the chair frame.

[0023] In the present invention, the limiting mechanism inclu...

Abstract

The invention discloses an anti-impact spring chair comprising a chair frame, a bottom buffer mechanism, a back buffer mechanism and a limiting mechanism, a cushion is mounted at the top of the chairframe, a backrest is mounted on one side of the top of the chair frame, supporting legs are welded to the bottom of the chair frame, the bottom buffering mechanism is arranged under the cushion, the back buffering mechanism is arranged on one side of the backrest, and the limiting mechanism is arranged in the center of one side of the chair frame. Through buffering and counteracting in the three directions, force acting on a chair and a human body is greatly weakened, and the safety of operators is effectively protected.

Description

technical field [0001] The invention relates to the technical field of mine disaster prevention and control, in particular to an anti-shock spring chair. Background technique [0002] With the increase of mining depth and intensity, rock burst has become one of the major disasters hindering the safe production of coal mines. In order to reduce its threat, various methods such as regional prevention and control, monitoring and monitoring, local hazard relief and on-site management have been adopted for comprehensive prevention and control. However, limited by the current level of theory and technical equipment, it is still impossible to prevent the occurrence of rock burst. Therefore, strengthening on-site management and effectively reducing or even eliminating the number of operators in dangerous areas of rock burst is the most effective way to reduce losses caused by rock burst appearance. However, due to the impact of mining and technical conditions, the pump workers, ele...
