Detailed Description
The embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in fig. 1, an anti-collapse supporting device for a roadway roof comprises a base 13 for supporting the supporting device, a fixed cylinder 12 fixedly connected to the base, a hydraulic device 11 installed at the bottom in the fixed cylinder and used for providing hydraulic supporting force, a bearing rod 7, a bearing platform 8, a protective cover 1 and a scissor-type supporting structure, wherein the fixed cylinder is detachable and is formed by fixedly connecting a left part and a right part, and a movement space and an action space can be provided for the bearing rod and other devices mainly when the bearing rod is provided with the supporting force in stages;
the bearing rod 7 is sleeved in the fixed cylinder 12, one end of the bearing rod is abutted against the hydraulic rod 10 of the hydraulic device 11, and the other end of the bearing rod is fixedly connected with the middle part of the bottom surface of the bearing platform 8, so that a stable bearing force body is provided for bearing above the platform; the bearing rod 7 is fixedly connected with a latch 9, a tooth groove is formed in the fixed cylinder 12, the latch 9 is matched with the tooth groove to provide initial bearing force for the bearing rod, when acting force borne by the bearing rod is larger than limit bearing of the latch 9, a latch acting structure fails, the latch breaks, the bearing rod descends and acts on the hydraulic rod; the latch is tightly suspended on the bearing rod in a screw shape and is not integrated with the bearing rod; the hydraulic device is characterized in that after the latch structure fails, the bearing rod acts on the hydraulic rod rapidly, the hydraulic rod bears force and transmits the force to the hydraulic device, the hydraulic device works and provides bearing force for the bearing rod through the hydraulic rod, and the hydraulic device can be connected externally;
the bearing platform 8 is connected with the protective cover 1 through a telescopic rod 4, a spring 5 is sleeved outside the telescopic rod 4, one end of the spring 5 is connected with the bearing platform 8, the other end of the spring 5 is connected with the protective cover 1, the telescopic rod and the spring are combined to provide bearing force in the vertical direction of the protective cover, and the protective cover is buffered again through the telescopic rod and the spring in a telescopic mode; the protective cover is used for bearing broken stones adjusted by the roof collapse; the bearing platform 8 provides a lower acting plane for devices such as a sliding chute, a sliding rod, a telescopic rod, a spring and the like, and provides supporting force for the devices;
cut formula bearing structure, the upper end is connected with the protection casing, and the lower extreme is connected with load-bearing platform, and specific formula bearing structure of cutting is: the device comprises two sliding rods 6, the middle parts of which are hinged, two ends of each sliding rod 6 are respectively connected with a bearing platform and a protective cover through sliding chutes 3 arranged on the bearing platform and the protective cover, the sliding rods 6 can move back and forth in the sliding chutes 3, the sliding rods 6 move back and forth in the sliding chutes according to the stress, the acting force applied by the protective cover is buffered and used for assisting in supporting the protective cover, and the sliding rods 6 are hinged and combined through balls to form a sliding rod group; the lifting of the protective cover can be realized by the movement of the sliding rod 6 and the telescopic rod 4, and meanwhile, the size of the device above the interface and the size of the device below the interface are in a ratio of 1:5 by taking the bearing platform as a boundary;
the protective cover is provided with a wingspan and further comprises a wingspan telescopic rod 2, one end of the wingspan telescopic rod 2 is hinged with the wingspan, the other end of the wingspan telescopic rod is hinged with the protective cover, two wings can be expanded outwards through the wingspan telescopic rod, and the protective space of the protective cover is enlarged.
When in use, the device is arranged in a region where the top plate is easy to generate rockfall or has larger deformation, wherein the base 13 is ensured to fall to the ground stably, and the protective cover 1 is contacted with the top plate, so that the protective cover can be contacted without being excessively close to the top plate; meanwhile, 5-6 sliding rods 6 are installed and provided with corresponding sliding chutes 3, and the elasticity of the telescopic rods and the springs needs to meet the requirement that the protective cover still can effectively stretch under heavy load; the wingspan telescopic rod 2 is used for effectively unfolding the side wings of the protective cover, and the side wings can be unfolded if necessary.
If the caving condition of the roadway roof is serious, the hydraulic device 11 can be externally connected, and the external hydraulic device is utilized to provide more sufficient hydraulic power.
Coal caving rock mass can accumulate around the device after a period of time and even block the safe passage under the device, so that the rock mass needs to be cleaned regularly.
The device latch 9 defaults to 3-5, and the latch is disposable, so the latch need be changed again in later stage multiplexing, and needn't change the carrier bar again, when the circumstances such as cylinder body latch draw-in groove wearing and tearing appear, need restore the cylinder body this moment even change.
It should be noted that, in the application process of the device, according to different roadway environments, the corresponding construction can be adjusted, for example, the number of the sliding rods or the clamping teeth and the like can be increased or decreased appropriately, whether the hydraulic device is externally connected or not can be adjusted, and the like.
