Abstract
The utility model discloses a novel anti-fracture anchor rod structure. According to the novel anti-fracture anchor rod structure, a casing pipe, a tray and a washer are sequentially fixed to a rod body in a penetrating mode from top to bottom, the middle portion of the casing pipe protrudes outwards, the top surface of the tray is concave inwards, the bottom surface of the tray is a plane, the casing pipe is arranged in the tray, a groove is formed in a pipe wall in the middle of the washer, the diameter of the bottom end of the rod body is larger than the diameter of the main part of the rod body, and the novel anti-fracture anchor rod structure further comprises an anti-fracture early warning device which is composed of a pressure analyzing module, a display module, an alarm module and a pressure sensor. The novel anti-fracture anchor rod structure is good in supporting effect, high in protective strength, and capable of effectively protecting an anchor rod against fractures.
Description
Technical field
The utility model relates to a kind of device that prevents tunnel supporting anchor rod fracture.
Background technology
Current mine timbering anchor poles made from Steel material that adopt more, when the roof pressure of anchor pole institute supporting is excessive, anchor pole is dared not accept pressure and is caused fracture because hold, thereby caused danger in tunnel, when being about to fracture, also cannot predicting, thereby easily cause the accident simultaneously.
Summary of the invention
The problems referred to above that exist for solving existing anchor pole, the utility model provides a kind of Novel anti-fracture anchor structure, its technical scheme of taking is: comprise the body of rod, and the sleeve pipe of being mutually close to, pallet and packing ring, sleeve pipe, pallet and packing ring intert and are fixed on the body of rod successively from the top down, the mid portion evagination of sleeve pipe, the end face indent of pallet, its bottom surface is plane, make sleeve pipe be positioned at pallet, the tube wall of the mid portion of packing ring is provided with groove, body of rod bottom diameter is greater than body of rod main diameter, this structure also comprises by Pressure Analysis module, display module, the anti-fracture prior-warning device that alarm module and pressure sensor form, wherein Pressure Analysis module respectively with display module, alarm module is connected with pressure sensor, pressure sensor is located at the top of the body of rod.
Sleeve pipe evagination can be protected pallet; and when being subject to pressing consumingly impact; the first stress deformation compensator or trimmer pressure of sleeve pipe, thus anchor pole is protected, and the structure of pallet can increase its bulk strength; packing ring can protect anchor pole to be not easy to be pulled off; body of rod bottom is thick can improve tensile strength, increases anchored force, and anti-fracture prior-warning device can show the pressure condition of anchor pole; and report to the police before anchor pole fracture prerequisite, prevent that contingency from occurring.
The utility model supporting effect is good, and protection intensity is high, can effectively prevent the fracture of anchor pole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structured flowchart of anti-fracture prior-warning device in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As depicted in figs. 1 and 2, sleeve pipe 2, pallet 3 and packing ring 4 are close to mutually, they intert and are fixed on the body of rod 1 successively from the top down, the mid portion evagination of sleeve pipe 2, the end face indent of pallet 3, its bottom surface is plane, makes sleeve pipe 2 be positioned at pallet 3, the tube wall of the mid portion of packing ring 4 is provided with groove, and the body of rod 1 bottom diameter is greater than the body of rod 1 main diameter.This structure also comprises the anti-fracture prior-warning device being comprised of Pressure Analysis module, display module, alarm module and pressure sensor, wherein Pressure Analysis module is connected with display module, alarm module and pressure sensor respectively, and pressure sensor is located at the top of the body of rod 1.
During use, also fixing in the insertion coal seam, top of the body of rod 1 or rock stratum, the bottom of the body of rod 1 can be fixed on auxiliary rack.The pressure sensor of anti-fracture prior-warning device can be pressure signal transmission to Pressure Analysis module, and shows pressure index by display module, and when pressure index is greater than setting pressure, Pressure Analysis module can be controlled alarm module and report to the police.
