Abstract
The utility model relates to a crack preventing safety retainer ring for an anchor rod. The safety retainer ring is provided with a ring-shaped sleeve ring at the bottom; the two sides of the safety retainer ring extend towards the inclined upper part to form support arms with hooks at the tail ends; the ring-shaped sleeve ring of the safety retainer ring is matched with an anchor rod head and sleeved with the anchor rod head; and the hooks on the two sides of the safety retainer ring are hung on a steel mesh. The sleeve ring on the safety retainer ring can tightly support the anchor rod head, so that people can not be injured by the broken anchor rod head; and the structure is simple.
Description
Technical field
The utility model relates to a kind of protector of underground mining, is that a kind of anchor pole prevents collapsing safe collar.
Background technology
At present, known underground mining guard system is to be made up of anchor pole, gauze wire cloth.System is fastening through packing ring and nut by steel column, anchor pole and gauze wire cloth, and institute's zone of protection is formed the stress protection, thereby prevents the avalanche tenesmus of the rock soil body; Play the effect of protection; But, in the process of protection, because anchor pole has high-intensity stress all the time; The anchor pole on gauze wire cloth top is easy to break, and this part that breaks can cause serious injury accident to personnel in the pit's personal safety.
The utility model content
The personnel in the pit is damaged easily the problem of accident for the fracture location that overcomes anchor pole; The utility model provides a kind of anchor pole to prevent collapsing safe collar; This anchor pole prevents that collapsing safe collar can make the position that breaks of anchor pole be stuck tightly, can fully guarantee underground work personnel's personal safety.
The utility model solves the technical scheme that its technical problem adopted: this safe collar comprises anchor pole, gauze wire cloth and safe collar, and this safety card snare is contained on the device of a cylindricality anchor pole silk head; This safe collar is the lasso that a bottom has annular, and its two side direction oblique upper extends, and forms the terminal support arm that has hook, and the circular lasso of a safe collar and anchor pole silk engage sleeves is installed, and the hook of the both sides of safe collar is hooked on the gauze wire cloth; When the anchor pole on the gauze wire cloth ruptured, the lasso on the safe collar will be held anchor pole silk head tightly, the anchor pole silk head of fracture can not collapsed fly to hurt sb.'s feelings.
This safe collar is the integral structure that steel bar folding circle folding colludes, and the diameter of its lasso is greater than the diameter of anchor pole silk head, less than the diameter of anchor pole locking nut.
The distance of this safe collar between the extended support arm of oblique upper should be greater than the diameter of anchor pole locking nut and packing ring, and the length of support arm is greater than the thickness of locking nut and packing ring.
The beneficial effect of the utility model is: the lasso on this safe collar can be held anchor pole silk head tightly, the anchor pole silk head of fracture can not collapsed fly to hurt sb.'s feelings, and is simple in structure.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of the utility model.
Among the figure, 1. anchor pole, 2. gauze wire cloth, 3. safe collar, 4. anchor pole silk head.
The specific embodiment
In Fig. 1, this safe collar comprises anchor pole 1, gauze wire cloth 2 and safe collar 3, and this safe collar 3 is sleeved on the device of a cylindricality anchor pole silk 4; It is characterized in that: this safe collar 3 is the lasso that a bottom has annular; Its two side direction oblique upper extends; Form the terminal support arm that has hook, the circular lasso of safe collar 3 and anchor pole silk 4 engage sleeves are installed, and the hook of safe collar 3 both sides is hooked on the gauze wire cloth 2; When the anchor pole on the gauze wire cloth 21 fracture, the lasso on the safe collar 3 will be held anchor pole silk 4 tightly, the anchor pole silk 4 of fracture can not collapsed fly to hurt sb.'s feelings.
In Fig. 1, this safe collar 3 is the integral structure that steel bar folding circle, folding collude, and the diameter of its lasso is greater than the diameter of anchor pole silk 4, less than the diameter of anchor pole 1 locking nut.
In Fig. 1, the distance of this safe collar 3 between the extended support arm of oblique upper should be greater than the diameter of anchor pole 1 locking nut and packing ring, and the length of support arm is greater than the thickness of locking nut and packing ring.
