Abstract
The utility model relates to a gate type rock burst prevention support, in particular to a gate type rock burst prevention support of the field of underground coal mine roadway support equipment. The support comprises a crown, landing legs, a clamping cable and an invert. The two ends of the crown are respectively in lap joint with the upper end of one landing leg and then connected with the upper end of one landing leg through the clamping cable, and the lower ends of the two landing legs are fixedly connected with the two ends of the invert respectively. The support is high in bearing capacity and high in stability, and has certain rock burst prevention capacity.
Description
[technical field]
The utility model relates to coal mine down-hole tunnel support apparatus field, especially relate to a kind of door type structure protecting against shock press support.
[background technology]
Known, bump claims again rock burst, refers to roadway or work plane surrounding rock body, because the instantaneous relase of elastic deformation energy produces the suddenly violent dynamic phenomenon destroying, often with coal and rock dish out, the phenomenon such as loud noise and blast; Because bump has very large destructiveness, and it is occurring as last there is no macroscopical omen, but with suddenly, sharply, fierce form dishes out coal and rock, thereby not only can cause support damage, wall caving roof fall or tunnel to stop up, but also can cause that constructor is injured by a crashing object, tumble injury or squeeze wound, when serious, even can make constructor stop up death by suffocation because of tunnel, therefore, bump is worldwide all regarded as one of the most serious natural calamity in coal mine; At present, along with the continuous increase of China's coal-mine mining depth, rock blast hazard also presents more and more serious trend, and this has caused great threat to the life security of Safety of Coal Mine Production and vast Coal Mine Staff.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of gate-type protecting against shock and press support, described support not only supporting capacity is strong, and stability is strong, but also has the ability of certain defence bump.
For achieving the above object, the utility model adopts following technical scheme:
Support is pressed on a kind of gate-type protecting against shock ground, and described support comprises crown, supporting leg, card cable and end arch; Described crown two ends are connected by card cable after overlapping with the upper end of a supporting leg respectively, and the lower end of two supporting legs is fixedly connected with the two ends of end arch respectively.
Support is pressed on described gate-type protecting against shock ground, and described crown, supporting leg or end arch are made as the U-shaped steel of whole, and the length of crown and supporting leg and radian all with the net section Corresponding matching of construction tunnel.
Support is pressed on described gate-type protecting against shock ground, and described termination, arch two ends, the end and termination, supporting leg lower end are welded with respectively one for by the corresponding steel plate being fixedly connected with of bolt.
Support is pressed on described gate-type protecting against shock ground, and the contact surface of described crown and supporting leg overlap joint is provided with rubber spacer.
Support is pressed on described gate-type protecting against shock ground, and described supporting leg encircles the end of with the contact surface being connected and is provided with rubber spacer.
Support is pressed on described gate-type protecting against shock ground, and described card cable is dual-trench type clamping plate type cast steel card cable.
Owing to adopting technical scheme as above, the utlity model has following beneficial effect:
Gate-type protecting against shock described in the utility model ground presses supporting structure simple, is easy to application; Described support can effectively strengthen supporting capacity and increase scalable amount, thereby not only effectively raises the ability of defence bump, but also has ensured accordingly the safety of equipment and constructor in tunnel.
[accompanying drawing explanation]
Fig. 1 is schematic diagram of the present utility model.
In figure: 1, crown; 2, supporting leg; 3, card cable; 4, end arch.
[specific embodiment]
By the following examples, can explain in more detail the present invention, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Support is pressed on gate-type protecting against shock described in 1 ground by reference to the accompanying drawings, and described support comprises crown 1, supporting leg 2, card cable 3 and end arch 4; For increasing supporting capacity, described crown 1, supporting leg 2 or end arch 4 can be made as to the U-shaped steel of whole, and the length of crown 1 and supporting leg 2 and radian are made as and the net section Corresponding matching of construction tunnel; Described crown 1 termination, two ends firmly links together by dual-trench type clamping plate type cast steel card cable 3 after overlapping with the termination, upper end of a supporting leg 2 respectively again, thereby reach, make the bolt that connects crown 1 and supporting leg 2 only bear longitudinal pulling force, and the object of not bearing cross shear, effectively increase the resistance to tension of connecting bolt, and then strengthened accordingly the bearing capacity of described support;
The lower end of two described supporting legs 2 is fixedly connected with the two ends of end arch 4 respectively, as required, can encircle the end of at the termination at 4 two ends and a block plate is welded respectively in the termination of supporting leg 2 lower ends, and then by bolt, the corresponding end steel plate of end arch 4 and supporting leg 2 is fixed together; In addition, for increasing the scalable amount of described support, the contact surface that can overlap at crown 1 and supporting leg 2 arranges rubber spacer, at supporting leg 2, with end arch 4 contact surfaces that are connected, rubber spacer is set, thereby reach the working resistance that increases described support, increase the object of the pretightning force of bolt and the scalable amount of support, and then strengthened accordingly the bearing capacity of described support.
When implementing gate-type protecting against shock described in the utility model and pressing support, only need by the net section shape of construction tunnel and in requisition for bearing capacity select corresponding crown 1, supporting leg 2 and end arch 4, then end arch 4 is placed on to ground stably, then the net section in crown 1 and supporting leg 2 corresponding tunnels is in place.
The utility model does not describe part in detail for prior art, therefore the utility model is not described in detail.
