Problems solved by technology
[0003] Existing protective devices include rigid protective devices and flexible protective devices. Rigid protective devices are bulky in structure, difficult to install, and have poor protective effects and are easily damaged
Most of the current flexible protective devices are connected to the hydraulic support with a flexible protective net to block one side of the hydraulic support, but there is still a safety hazard of coal flying into two adjacent hydraulic supports

Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as figure 1 The flexible protection device between the adjacent frames of the hydraulic support of the present invention includes a telescopic support rod 1 arranged on each hydraulic support 7, a lateral support rod 5 connected to the telescopic support rod 1, and a flexible folding rod connected to the lateral support rod 5 Protective net6.
[0026] Such as figure 1 The telescopic support rod 1 is installed between the top beam 71 and the base 72 of the hydraulic support 7. The telescopic support rod 1 has three sections, including a fixed rod 11 at the bottom end and a first movable rod set inside the fixed rod 11. 12 and the second movable rod 13 that is enclosed within the first movable rod 12, the diameter of the second movable rod 13 is smaller than the first movable rod 12, and the diameter of the first movable r...

A flexible protection device between adjacent frames of a hydraulic support, comprising a telescopic support rod installed between the top beam and the base of the hydraulic support, the top and bottom of the telescopic support rod are provided with connectors, the connectors are connected with universal joints, The universal joint is connected to the horizontal support rod, which can be set telescopically. The horizontal support rod is connected to the telescopic support rod of the adjacent hydraulic support through the universal joint. The flexible folding protective net is connected to the horizontal support rod, so that the flexible folding The protective net can be blocked between adjacent hydraulic supports to prevent coal from splashing in, which is safe and reliable; the lateral support rod can be extended and retracted. When the hydraulic supports move forward, the universal joint can ensure that the space between two adjacent hydraulic supports There is a corresponding angle between them to avoid breaking the horizontal support rod, and the telescopic horizontal support rod elongates with the forward movement of the hydraulic support to ensure the smooth movement of the hydraulic support.
Description
technical field [0001] The invention relates to the technical field of mining machinery, in particular to a protection device for adjacent frames of a hydraulic support. Background technique [0002] At present, mechanized comprehensive mining of coal mines is very common. During the coal mining process, the coal cut by the shearer and the gangue flying into the worker's work space often occur. The splashed coal and gangue can easily injure the staff and workers. 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. [0003] Existing protective devices include rigid protective devices and flexible protective devices. The rigid protective devices have a bulky structure, are not easy to install, and have poor protective effects and are easily damaged. Most...
