Embodiment Construction
[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0014] Such as figure 1 and figure 2 Commonly shown, the hydraulic support protective net device includes a flexible protective net 3 arranged between the hydraulic support top beam 1 and the cable groove 2, the hydraulic support top beam 1 is provided with a protective net expansion rod 4, and the protective net expansion rod The two ends of 4 are bent, and there is a gap through which the flexible protective net 3 passes between the middle part and the hydraulic support top beam 1. One end of the flexible protective net 3 is connected to the cable groove ...

The invention discloses a hydraulic support protection net device, belonging to the technical field of mining machines. The hydraulic support protection net device comprises a flexible protection net which is arranged between a hydraulic support top beam and a cable trough. A protection net unfolding rod is arranged on the hydraulic support top beam. One end of the flexible protection net is connected onto the cable trough and the other end of the flexible protection net is connected with an elastic retractable element through the protection net unfolding rod. A rigid rod is arranged at one end of the flexible protection net, which is connected with the elastic retractable element. By using the device, the protection space is effectively widened; the personal safety and the equipment safety are protected; when a scraper conveyer moves, the elastic retractable element can compensate the protection space of the flexible protection net to prevent a large open area from occurring between the hydraulic support top beam and the scraper conveyer and to further protect the working personnel and the equipment; the structure is simple, light and ingenious; and the protection effect is good.
Description
technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a protective net device for a hydraulic support. Background technique [0002] At present, mechanized comprehensive mining of coal mines is very common. During the coal mining process, the coal and gangue cut by the shearer often fly into the work space of workers. The splashed coal and gangue are very easy to injure the staff and Damage to comprehensive mining equipment, resulting in extremely serious personal and equipment safety accidents. Therefore, installing a protective device between the shearer and the worker's workspace has also attracted the attention of many hydraulic support manufacturers. However, most of the existing protective devices are rigid gangue board structures or use waste conveyor belts to play a protective role. These structures are heavy and have poor protective effects. Contents of the invention [0003] The purpose of the embo...
