Abstract
The utility model relates to an anchor cable retractable connector for a steel beam. The anchor cable retractable connector comprises a sleeve and a retractable device, wherein two anchor cable hole sides of the sleeve are respectively provided with a common anchor cable lockset; one side of the sleeve is opened and other side of the sleeve is provided with two anchor cable holes; the retractable device comprises solid connectors and two parallel springs arranged between the two solid connectors; the two ends of the springs are respectively and fixedly connected with the two solid connectors; axes of the springs are aligned to the anchor cable holes of the solid connectors; and the retractable device is placed in the sleeve. Two anchor cables with the same direction on the steel beam can penetrate through different anchor cable holes in the two ends of the retractable connectors and then are locked by using the anchor cable locksets; when the anchor cables are tensioned, the springs in the retractable connectors are pressed to generate certain degree of retraction displacement; and meanwhile, the anchor cable retractable connector has the high resistance and can achieve high-resistance yielding, so that the retractable requirements of the large-rigidity steel beam and an anchor cable support are met.
Description
Technical field
The utility model relates to a kind of for the anchor cable contractibility connector on girder steel.
Background technology
At present, the combined supporting of large rigidity girder steel and anchor cable is widely used in the large distortion coal road of high-ground stress and half rock coal road, due to the control effect highly significant of this support form to heavily stressed weak surrounding rock, therefore, provide advantage to the production environment of improving bargh, thereby greatly improved the resource recovery ratio in mine, reduced cost of production.But, existing anchor cable can the contracting amount less, and in the supporting of deep-well high stress coal roadway, require supporting and protection structure to have certain contractibility, satisfy couple hardness with softness, high resistant allows the supporting principle of pressing.
The utility model content
In order to solve the problems of the technologies described above, it is a kind of simple in structure, can the contracting amount large, practical a kind of for the anchor cable contractibility connector on girder steel that the utility model provides.
The technical scheme that the utility model solves the problems of the technologies described above is: comprise sleeve and yieldable means, sleeve both sides anchor cable hole side is respectively arranged with two common anchor cable locks, described sleeve one side opening, opposite side is provided with two anchor cable holes, described yieldable means comprises entity connector and two springs that are parallel to each other that are provided with between two entity connectors, the two ends of described spring are fixed in respectively on two entity connectors, axle of spring aligns with entity connector anchor cable hole, and described yieldable means is placed in sleeve.
The slightly larger in diameter of above-mentioned anchor cable hole is in the diameter of anchor cable.
The size of above-mentioned yieldable means and the size of sleeve are complementary.
OnStating sleeve is made by plain cast iron.
Above-mentioned entity connector is made by two blocks of common cast irons.
The beneficial effects of the utility model are: after two anchor cables in opposite directions on girder steel are passed in the different anchor cable holes in contractibility connector two ends, lock with anchor cable lock respectively again, spring in yieldable means after anchor cable tension produces to a certain degree contraction displacement because of pressurized, has again simultaneously higher resistance, realize that high resistant allows pressure, thereby reach the contractibility requirement of large rigidity girder steel and Application of Combined Support with Anchor.
Description of drawings
Fig. 1 is the utility model each several part structural representation;
Fig. 2 is overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
referring to Fig. 1, the utility model comprises sleeve 3 and the yieldable means that can be free to slide, described sleeve 3 left side openings, its right side is provided with two anchor cable holes 4 in up and down, the slightly larger in diameter of anchor cable hole 4 is in the diameter of anchor cable 6, described yieldable means comprises entity connector 1, be provided with two springs that are parallel to each other 2 in the middle of two entity connectors 1, the two ends of described spring 2 are fixed in respectively on two entity connectors 1, and spring shaft aligns to the anchor cable hole with the entity connector, described yieldable means is placed in sleeve 3, the size of the size of described yieldable means and sleeve 3 is complementary, sleeve 3, entity connector 1 is made by plain cast iron, spring 2 is large rigidity, high-intensity steel are made, the median pore diameter of spring 2 is slightly larger than the diameter of anchor cable.
Referring to Fig. 2, sleeve 3 both sides are respectively arranged with on two anchor cable holes up and down that 5, two anchor cable locks 5 of two common anchor cable locks are fastened on respectively sleeve 3 both sides.
Operating principle of the present utility model is: after the anchor cable 6 of two opposite directions on girder steel is passed in the anchor cable hole 4 at contractibility connector two ends and the spring 2 respectively, respectively with anchor cable lock 5 lockings, the contractibility of so just having completed anchor cable 6 on high rigidity girder steel connects again.Spring 2 in contractibility connector after anchor cable 6 tension produces to a certain degree contraction displacement because of pressurized, realizes that high resistant allows pressure, thereby reaches the contractibility requirement that large rigidity girder steel adds cable bolting.Can the contracting amount and the size of resistance regulated by material and the length of spring according to Hooke's law.
Above content described in this manual is only to the explanation of the utility model structure example.The various modifications that the described specific embodiments of the utility model is made, replenish; perhaps adopt similar mode to replace; only otherwise depart from structure of the present utility model, perhaps do not surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
