Abstract
The utility model relates to an expansion anchor rod capable of being used repeatedly, relating to a support device, in particular to relates to an anchor rod capable of being used repeatedly for tunneling during mining and rock excavation. The aim is that providing the anchor rod which can be repeatedly used and can save resources. The expansion anchor rod capable of being used repeatedly comprises a main rod body, an auxiliary rod body, a block plate and a fastening bolt, the auxiliary rod body is sleeved on the main rod body, the front end of the main rod body is provided with a cone body, and the front part of the auxiliary rod body is provided with at least two elastic expansion plates. When the cone body arranged at the front end of the main rod body is arranged deep into the auxiliary rod body, the expansion plates on the front part of the auxiliary rod body can be expanded to squeeze surrounding rocks and increase the anchoring force, and thus the anchor rod can be fixed in the rocks to realize anchoring. When the anchor rod does not need to be used, the fastening bolt and the block plate are removed, the expansion plates on the front part of the auxiliary rod body restore the original shapes, the auxiliary rod body and the main rod body are then removed, and the operation is simplified. Therefore, the anchor rod can be used repeatedly and the resources can be saved.
Description
Technical field
The utility model relates to a kind of suspension device, reusable anchor pole when particularly relating to a kind of mine and rock mass opening driving.
Background technology
Bolt support has a wide range of applications in the rock mass engineering project of many departments such as mine, tunnel, highway.Present anchor pole mainly contains formations such as baffle plate, the body of rod, anchored end, during use, at first utilizes rig on rock mass, to hole; In body of rod load hole, expand and the surrounding rock body chucking through anchored end, produce frictional resistance; Baffle plate is held the rock mass outer wall, utilizes the anchoring pulling force, and just anchored end and pallet are to the extruding force of casing; By many anchor pole actings in conjunction, the roadway surrounding rock in institute's anchoring scope is formed a whole the opposing pressure from surrounding rock.Mostly anchor pole is disposable input, in case no longer take out after the i.e. anchoring, but in the short engineering of some lengths of service; Caused the waste of resource; And for follow-up work, as for the temporary working under the coal mine, the anchor metal that can not take out also can influence normally carrying out of mechanical coal mining.
The utility model content
The technical problem that the utility model will solve provides a kind of simple in structure, expansion type roof bolt that cost is low, easy and simple to handle, and this anchor pole can be reused, and has practiced thrift resource, for interim coal road, also can not hinder the carrying out of next procedure.
The reusable formula expansion anchor rod of the utility model comprises main rod body, baffle plate and fastening bolt, and baffle plate and fastening bolt are installed in the main rod body rear portion; This anchor pole also comprises the secondary body of rod, and the secondary body of rod becomes the pipe shape, is sleeved on the main rod body; Front end in main rod body is provided with a cone; The big end of cone forward, small end extend in the secondary body of rod, secondary body of rod front portion is provided with at least two elastic expansion sheets.
The reusable formula expansion anchor rod of the utility model, the tail end of wherein said main rod body is provided with clamping part.
The utility model is reused formula expansion anchor rod difference from prior art and is, is deep in the secondary body of rod through the cone that is arranged on the main rod body front end, and the anterior expansion piece of the secondary body of rod is opened; The extruding surrounding rock body; Increase anchored force, anchor pole is fixed in the rock mass, form anchoring; In the time need not using anchor pole, fastening bolt and baffle plate to be unloaded, the expansion piece reinstatement that the secondary body of rod is anterior gets final product the main rod body taking-up after then the secondary body of rod being taken out again, and is easy and simple to handle; Therefore, this anchor pole can use repeatedly, has practiced thrift resource.And can practice thrift the temporary lining of a large amount of soft rock boring head for gun diging face and perhaps fix the wasting of resources of holing.
Below in conjunction with accompanying drawing the reusable formula expansion anchor rod of the utility model is described further.
Description of drawings
Fig. 1 looks sectional view for the master of the reusable formula expansion anchor rod of the utility model;
Fig. 2 is the structural representation (expansion piece distending state) of the secondary body of rod in the reusable formula expansion anchor rod of the utility model;
Fig. 3 looks sectional view (expansion piece distending state) for the right side of the reusable formula expansion anchor rod of the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2, the reusable formula expansion anchor rod of the utility model comprises main rod body 1, the secondary body of rod 4, baffle plate 2 and fastening bolt 3.1 one-tenth of main rod body is cylindric, is welded with one at the front end of main rod body 1 and holds towards precentrum 5 greatly, and the rear portion of main rod body 1 is processed with the screw thread that matches with fastening bolt 3, in the rear end of main rod body 1, and the rear side that is positioned at screw thread to be provided with cross section be oblong clamping part 8; 4 one-tenth pipe shapes of the secondary body of rod are sleeved on the main rod body 1, and wherein the small end of the cone 5 of main rod body 1 front end extend in the secondary body of rod 4, and 6, three otch 6 of the otch distance between any two that offers three the secondary body of rod 4 axis directions in edge on the sidewall of the secondary body of rod 4 front portions equates; On the secondary body of rod 4, constitute expansion piece 7 between two adjacent otch 6, the secondary body of rod 4 is processed by polyvinyl chloride or No. 45 steel; 2 one-tenth on baffle plate is discoid, is sleeved on the main rod body, and the front end face of baffle plate 2 contacts with the rear end face of the secondary body of rod 4, and fastening bolt 3 is installed in the rear portion of main rod body 1, and the front end face of fastening bolt 3 contacts with the rear end face of baffle plate 2.
The reusable formula expansion anchor rod of the utility model at first punches on the rock mass of anchoring needing in use, and this anchor pole is inserted in the hole; Contact with the rock mass external surface up to baffle plate, then fastening bolt is tightened, simultaneously with the fixing clamping part of main rod body rear end of spanner; Prevent the main rod body rotation, as shown in Figure 3, along with tightening of fastening bolt; The cone 5 of main rod body 1 front end is backed down the expansion piece 7 of secondary lever front end, and expansion piece extruding surrounding rock body increases anchored force; Anchor pole is fixed in the rock mass, forms anchoring; In the time need not using anchor pole, fastening bolt and baffle plate are unloaded, inside hammering main rod body makes it the secondary relatively body of rod and moves inward, and the expansion piece reinstatement that the secondary body of rod is anterior gets final product main rod body and the taking-up of the secondary body of rod then.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
