Abstract

The utility model relates to a yieldable lock device for supporting and protecting an anchor cable or an anchor cable beam. The yieldable lock device for supporting and protecting the anchor cable or the anchor cable beam comprises a sleeve and a yieldable device. An open mouth is formed in the left side of the sleeve, and an anchor cable hole is formed in the right side of the sleeve. The yieldable lock device is composed of an anchor cable lock, an annular steel sheet and a high intensity spring. The left surface of the steel sheet is tightly attached to the anchor cable lock, and the right surface of the steel sheet is connected with one end of the high intensity spring. The yieldable device is installed inside the sleeve from one side where the open mouth of the sleeve is formed. The other end of the high intensity spring is tightly attached to the side where the anchor cable hole is formed. When the anchor cable is tightly pulled, a certain degree of contraction displacement of the high intensity spring in the yieldable device is generated, and a certain initial pre-stress is provided. When a surrounding rock continuously deforms, larger contraction displacement of the high intensity spring is generated, larger resisting force is generated, and therefore the purpose of high resistance pressure yielding is achieved.

Description

It is a kind of to be used for anchor cable or the contractibility lock device of anchor cable beam supporting
Technical field
The utility model is related to a kind of lock device, more particularly to a kind of to be used for anchor cable or the contractibility lock device of anchor cable beam supporting. 
Background technology
As mining mineral resource develops to deep, the Deep Soft Rock tunnel of increasing high-ground stress, High-geotemperature and high karst water is showed, with deflection is big and the features such as continuous deformation, it is desirable to the characteristics of supporting construction has suitable for surrounding rock large deformation.Anchor cable or the supporting of anchor cable beam play irreplaceable effect as a kind of active support form in Deep Soft Rock roadway support, especially the control effect highly significant to high-ground stress weak surrounding rock, are greatly improved resource recovery ratio and reduction cost of winning.At present, although anchor pole and cable bolting structure all have certain contractibility, but can contracting amount it is little, it is impossible to the large deformation feature of suitable for surrounding rock, therefore anchor cable often occur and the phenomenon such as be pulled off. 
Utility model content
In order to solve the above-mentioned technical problem, the utility model, which provides one kind, can allow anchor cable to adapt to roadway surrounding rock large deformation, and applied to anchor cable or the contractibility lock device of anchor cable beam supporting. 
The technical scheme that the utility model solves the above problems is:Including sleeve and yieldable means, it is open on the left of the sleeve, right side sets an anchor cable hole, the yieldable means is made up of anchor cable lock, annular steel disc and high-strength spring, it is close to anchor cable lock in the left side of steel disc, the right side is fixed in one end of high-strength spring, and the yieldable means is placed among sleeve from sleeve openings side, and the other end of high-strength spring is close to sleeve anchor cable hole side. 
The size of above-mentioned yieldable means matches with sleeve dimensions. 
The opening diameter of above-mentioned sleeve anchor cable hole is slightly larger than anchor cable diameter but is slightly less than the diameter of high-strength spring. 
Above-mentioned steel disc is annular steel disc. 
The beneficial effects of the utility model are:High-strength spring after anchor cable is tensed in contractibility connector produces a certain degree of contraction displacement because of compression, and certain structural initial pre stress is provided to anchor cable;When country rock continuous deformation, increased with the tension on anchor cable, the compression suffered by yieldable means also increases so that high-strength spring produces bigger compression displacement, bigger resistance is produced, so as to reach that anchor cable adapts to the purpose of the large deformation of country rock. 
Brief description of the drawings
Fig. 1 is the structural representation of the utility model contractibility lockset. 
Fig. 2 is that the utility model is used for the structural representation of cable bolting. 
Fig. 3 is that the utility model is used for the structural representation of anchor cable beam supporting. 
Embodiment
The utility model is further described with reference to the accompanying drawings and examples. 
Referring to Fig. 1, the utility model includes slidable sleeve 4 and yieldable means 7, the left end opening of sleeve 4, right-hand member sets an anchor cable hole 5, the yieldable means 7 includes anchor cable lock 1, annular steel disc 2, high-strength spring 3, the internal diameter of annular steel disc 2 is equal to the aperture of anchor cable hole 5, external diameter is slightly less than the internal diameter of sleeve 4, it is close to the side of anchor cable lock 1 in the left side, the right side is fixed in the one end of high-strength spring 3, the high-strength spring 3 is made up of big rigidity, high strength steel, and the affixed annular steel disc 2 of left end, right-hand member is close to the side of anchor cable hole 5 of sleeve 4. 
Referring to Fig. 2, Fig. 3, the contractibility lockset can be used for the contractibility supporting of anchor cable and anchor cable beam, anchor cable backing plate 8 be provided between contractibility lockset 7 and lane side rib, the contractibility supporting of anchor cable is just completed.At the anchor hole up and down for the both sides of anchor cable connector 9 contractibility lockset 7 being separately mounted on anchor cable beam, the contractibility supporting of anchor cable beam is so just completed. 
The operation principle of the utility model anchor cable contractibility supporting:Anchor cable 6 is worn and locked out of backing plate 8 and contractibility lock device 7 anchor cable hole 5 successively, this completes the connection of the contractibility of cable bolting stream line 6;High-strength spring 3 after anchor cable 6 is tensed in contractibility lockset 7 produces a certain degree of contraction distortion because of compression, and certain structural initial pre stress is provided to anchor cable 6;When country rock continuous deformation, increased with the tension on anchor cable 6, the compression suffered by contractibility lock device also increases so that high-strength spring 3 produces compression, so as to reach that anchor cable 6 adapts to the purpose of the large deformation of country rock. 
The operation principle of the utility model anchor cable beam contractibility supporting:A contractibility lock device 7 is each passed through after two on anchor cable beam opposite anchor cables 6 are passed through out of different anchor cable holes of the both sides of anchor cable connector 9 respectively again and anchor cable is locked, this completes the connection of the contractibility of anchor cable beam supporting stream line 6;High-strength spring 3 after anchor cable 6 is tensed in contractibility lockset 7 produces a certain degree of contraction distortion because of compression, and certain structural initial pre stress is provided to anchor cable 6;When country rock continuous deformation, increased with the tension on anchor cable 6, the compression suffered by contractibility lock device also increases so that high-strength spring 3 produces compression, so as to reach that anchor cable 6 adapts to the purpose of the large deformation of country rock. 
The utility model can be used among the support technologies relevant with anchor cable such as the cable bolting in deep-well, anchor rope truss supporting.Using above technical scheme, the related contractibility of deep-well cable bolting can be effectively realized, its supporting effect is reached most preferably. 
Above instantiation is only a kind of preferable example of the utility model, but not the utility model content is whole, and all equivalents done in the utility model scope all will be within the utility model protection domain.
