Abstract
A safety protection device for ends of an exposed rod belongs to the technical field of mine support equipment, and is used for preventing people hurt accidents when staff walk to be collided and ejection of anchor cables, anchor rods and clamp cables due to crack. The technical scheme includes that the safety protection device comprises an inner sleeve and an outer sleeve which are both cylindrical sleeves respectively with one closed end; the inner sleeve is made of hard materials; the outer sleeve is made of soft materials; the outer sleeve is sleeved on the periphery of the inner sleeve; an elastic lock opening is arranged on an end opening of the outer sleeve; and the elastic lock opening is closely wrapped at the end of the exposed rod on the upper portion of the end opening of the inner sleeve. In the safety protection device for the ends of the exposed rod, hard materials in the inner layer can function in safety protection when the ends of the rod are impacted by external force, soft rubber on the outer layer can contact buffering of the stressed two articles, and the inner layer and the outer layer can buffer and reduce penetrating capacity of end breaking of the rod. The safety protection device has the advantages of scientific integral structure, simplicity, low cost, uneasy falling, beauty and practicality, and is convenient in installation.
Description
Technical field
The utility model relates to shaft-like supportings such as a kind of colliery, non-coal mine anchor cable, anchor pole, metal shed card cable and exposes the safety device of termination, belongs to the mine support equipment technical field.
Background technology
Under underground and massif in colliery, non-coal mine and the tunnel construction, anchor cable, bolt support technology are widely used at present.According to technological requirement, anchor cable and anchor pole all must have the afterbody of exposing, and especially during cable bolting, because Handicraft utensil restriction and return and withdraw the anchor technological requirement, it is exposed size special requirement.Expose at afterbodys such as anchor cables under the objective condition of existence, because head-room restriction or tunnel are under the influence of mine pressure such as geostatic stress, sink, when causing lane space to reduce, generation personnel head or other position of health and the anchor cable injured accident of colliding with of walking repeatedly once in the colliery, What is more, when anchor cable is disrumpent feelings for some reason, suddenly penetrate, cause below personnel's penetrability severe injury and death by accident, therefore the security protection that anchor cable etc. is exposed supporting body of rod termination is very necessary.At present constituent parts is taked simple and easy processing more, as the cover mineral water bottle, increase temporary measures such as reflection alarming bar, it is reported also to have and use insulating sponge to wrap up protection, but from its protection effect and application, not a kind of as yet specification product is realized.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can the solution personnel walking collide with and anchor cable, anchor pole, the fracture of card cable are penetrated casualty accident and taken place, what also help anchor pole, the observation of anchor cable construction quality exposes body of rod termination protector.
The technical scheme that solves the problems of the technologies described above is:
A kind of body of rod termination safety device that exposes, it is made up of inner sleeve and outer sleeve, inner sleeve and outer sleeve are the cylindrical sleeve of end sealing, inner sleeve is that hard material is made, outer sleeve is that elastic soft material is made, outer sleeve is sleeved on the inner sleeve periphery, the inner sleeve internal diameter with expose body of rod end diameter and be complementary, the outer sleeve port has the elasticity fore shaft of being longer than the inner sleeve port, the internal diameter of elasticity fore shaft is less than exposing body of rod end diameter, tight-lipped close the exposing on the body of rod end of inner sleeve port top of being wrapped in of snap lock.
The above-mentioned body of rod termination safety device that exposes, the blind end of the cylindrical sleeve of described inner sleeve and outer sleeve is a hemispherical ends.
The above-mentioned body of rod termination safety device that exposes, described inner sleeve are that hard plastic material is made, and outer sleeve is that soft rubber material is made.
The above-mentioned body of rod termination safety device that exposes has annular reflecting strips on the outer sleeve periphery.
That adopts this structure exposes body of rod termination safety device, the internal layer duroplasts can play the effect of security protection when being subjected to external impacts in body of rod end, outer soft rubber can play the stressed both sides' of contact buffering, ectonexine is fitted together, and can also play buffering and reduce the body of rod most advanced and sophisticated penetration capacity that breaks.This device have the overall structure science, simple, cost is low, easy for installation, difficult drop-off, both artistic and practical advantage, the observation and the quality that help anchor pole, anchor cable construction improve.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: body of rod end 1, inner sleeve 2, outer sleeve 3, keeper 4, hemispherical ends 5, annular reflecting strips 6.
The specific embodiment
Show among the figure that the utility model is made up of inner sleeve 2 and outer sleeve 3.
In inner sleeve 2 outsides is outer sleeve 3, outer sleeve 3 is elastomeric flexible protective jackets, the part profile that is sleeved on inner sleeve 2 is identical with inner sleeve 2, its internal diameter is identical with inner sleeve 2 external diameters, outer sleeve 3 ports have the elasticity fore shaft 4 of being longer than inner sleeve 2 ports, the internal diameter of elasticity fore shaft 4 is less than exposing body of rod end 1 diameter, and elasticity fore shaft 4 closely is wrapped in exposing on the body of rod end 1 of inner sleeve 2 port tops.When assembling was used, elasticity fore shaft 4 dependence elastic force were held tightly and are exposed the body of rod, prevent that the whole protection device from coming off.
Increase annular reflecting strips 6 outside the soft protective jacket of outer sleeve 3, purpose is to make the staff can find projections such as anchor cable in a distant place under the light, and caution is dodged.
Easy for installation for making, this device is inserted in inner sleeve 2 in the outer sleeve 3 adding man-hour, and cover implantation site and collar extension are neat, and elasticity fore shaft 4 elastic force that utilize outer sleeve 3 are the hard protection cap fixedly.When mounted, be inserted in anchor cable etc. and expose the body of rod and slightly firmly one push away, then the hard protection cap of inner sleeve 2 enters in the cover fully, and elasticity fore shaft 4 elastic force are also normally held anchor cable etc. tightly, reach the fixed protection effect.
