Detachable multiplexing single hole clip type anchor cable ground tackle
Technical field
The present invention relates to the anchoring support device of a kind of mine and geotechnical engineering, specifically, relate to a kind of detachable multiplexing single hole clip type anchor cable ground tackle.
Background technology
Cable bolting is widely used in Industrial Engineering such as colliery roadway, tunnel, side slope and ground stabilization, can be to big pretightning force and working resistance be provided by the anchor rock mass, security protection and reinforcement ability are 3~5 times of common bolt, owing to have flexibility, can realize installing greater than the deep hole of head-room, become one of indispensable supporting means of deep-well high-low pressure soft-rock tunnel.During Mine anchorage cable was used, the most extensive with the single hole clip type, its lockset constituted intermediate plate, anchor slab and pallet three parts, and wherein intermediate plate can be 2 chips or 3 chips, and all the other are all the integral type parts.After the anchor cable carrying, elongation rate is little, rigidity is strong, again pressurization after can not unloading, intermediate plate and anchor slab can not reclaim, often need in the repairing type tunnel anchor cable is carried out destructiveness cutting, thus can not the secondary anchoring, carry out in the volatile stope drift active workings of caving at needs, it is big to remove top board and ground tackle impact in the anchor cable hidden danger of hurting sb.'s feelings.
Summary of the invention
At above-mentioned deficiency of the prior art, the invention provides a kind of simple in structurely, easy to make, can treat and prevent the detachable multiplexing single hole clip type anchor cable ground tackle of multiple disease.
The technical solution used in the present invention is:
A kind of detachable multiplexing single hole clip type anchor cable ground tackle, comprise big pallet, one-level anchor slab, intermediate plate and anchor cable, anchor cable is arranged on the middle part, the anchor cable arranged outside has intermediate plate, the intermediate plate arranged outside has the one-level anchor slab, one-level anchor slab front end is provided with big pallet, and anchor cable runs through the through hole of big pallet, and described one-level anchor slab is made of two conically shapeds of splitting; The secondary anchor sleeve-board is contained in the external surface of one-level anchor slab; Secondary anchor slab and one-level anchor slab are provided with stopping means.
Described stopping means comprises that the ring-type stopper slot and the secondary anchor slab that are arranged on one-level anchor slab middle part radially are symmetrical arranged the perforation spacing hole; Spacing hole is disposed with position-limitting pin, rubber column and fastening bolt from inside to outside.
Be provided with little pallet between described one-level anchor slab and big pallet.
Described little pallet middle part is provided with locating slot; Insert in the locating slot one-level anchor slab end.
The beneficial effect of the relative prior art of the present invention:
The detachable multiplexing single hole clip type anchor cable ground tackle of the present invention, have lock members and dismantle multiplexing function, remove safe ready, mounting method is compared not change with equipment with conventional lockset, solid and reliable, the pallet power transmission is even, handling ease, material source is extensive, can realize that back the returning of adopting of pressure anchoring and coal-face crossheading support that allow of soft-rock tunnel removed.

The specific embodiment
It is following that the present invention will be described in detail with reference to drawings and Examples:
Accompanying drawing 1 as can be known, a kind of detachable multiplexing single hole clip type anchor cable ground tackle, comprise big pallet 1, one-level anchor slab 3, intermediate plate 8 and anchor cable 9, anchor cable 9 is arranged on the middle part, anchor cable 9 arranged outside have intermediate plate 8, and intermediate plate 8 arranged outside have one-level anchor slab 3, and one-level anchor slab 3 front ends are provided with big pallet 1, anchor cable 9 runs through the through hole of big pallet 1, and described one-level anchor slab 3 is made of two conically shapeds of splitting; Secondary anchor slab 4 is sleeved on the external surface of one-level anchor slab 3; Secondary anchor slab 4 is provided with stopping means with one-level anchor slab 3; Described stopping means comprises that the ring-type stopper slot and the secondary anchor slab 4 that are arranged on one-level anchor slab 3 middle parts radially are symmetrical arranged perforation spacing hole 11; Spacing hole 11 is disposed with position-limitting pin 5, rubber column 7 and fastening bolt 6 from inside to outside; Described one-level anchor slab 3 and big 1 on pallet are provided with little pallet 2; Described little pallet 2 middle parts are provided with locating slot 12; Insert in the locating slot 12 one-level anchor slab 3 ends.
The detachable multiplexing single hole clip type anchor cable ground tackle of the present invention, have lock members and dismantle multiplexing function, remove safe ready, mounting method is compared not change with equipment with conventional lockset, solid and reliable, the pallet power transmission is even, handling ease, material source is extensive, can realize that back the returning of adopting of pressure anchoring and coal-face crossheading support that allow of soft-rock tunnel removed.
The detachable multiplexing single hole clip type anchor cable ground tackle of the present invention, processing method is simply easy, and material source is extensive; , utilize two operating positions of the relative one-level anchor slab of secondary anchor slab, realize that one-level anchor slab locking to the split design is with lax; Offer stopper slot in the middle part on the one-level anchor slab, symmetry is offered the perforation spacing hole on the secondary anchor slab, position-limitting pin, rubber column and fastening bolt are installed in the hole, can realize to the locking of one-level anchor slab with unclamp, wherein rubber column can play to press and cut protective effect pin and bolt, guarantees its action flexibly in spacing hole; Lockset remove to adopt the socket wrench specially adapted for it roof pressure to remove, and is guiding with the anchor cable, after connect special-purpose unloader or hydraulic prop, can realize security protection that top board, lockset release are impacted also can during unloading, providing certain supporting drag, prevent that top board from collapsing; Have a shallow locating slot in the middle of the little pallet, can locate the one-level anchor slab, do not influence the spreading of one-level anchor slab bucket wall again, also have the evenly big stressed function of pallet; Lockset allows pressure as the need anchor cable in the soft rock large deformation tunnel, can remove the back secondary installing to lockset, avoids steel strand to be broken because elongation per unit length crosses low, also is beneficial to and realizes that with other support form rigidity is coupled; Lockset and metallic support form the collaborative supporting of canopy lock, can realize that the back of adopting of coal mining work plane crossheading support returns and to remove, anchor cable is removed with lockset and is recovered in upper and lower side head position, has saved for canopy material and man-hour, advance support district and end support district safety and firmness, sectional space is open.
