Abstract
The utility model relates to an OV steel disc for anchoring. The OV steel disc for anchoring solves the problems that mine underworkings shoring surrounding rock is little in contact area, small in flexibility and poor in stability, the self-supporting capability of the surrounding rock is insufficient and rock leaks. The OV steel disc for anchoring is characterized in that an oval steel disc body (1) is arranged; a V steel plate (3) is arranged in the oval steel disc body (1) and machined into an OV steel disc; a through hole (2) for being connected with an anchor rod is formed in the OV steel disc. The OV steel disc for anchoring has the advantages that surrounding rock is large in contact area, large in flexibility and good in stability, the rock is prevented from leaking and the self-supporting capability of the surrounding rock can be fully made use of and the OV steel disc for anchoring is suitable for mine underworkings shoring application.
Description
Technical field
Utility model is specifically related to OV shaped steel dish for a kind of anchoring, belongs to the technical field that mine down-hole tunnel support apparatus is made, and is adapted to mine down-hole tunnel supporting application.
Large, flexible large, the anti-leak-stopping rock of country rock contact area, can support large deformation and press, the OV shaped steel dish for anchoring of performance country rock self-supporting ability.
Background technology
At present, known Xishan coal electricity Co., Ltd " ' W ' shaped steel belt used for anchoring for mine ", the patent No. is at zL00264256.5, this steel band is shaped with the outstanding reinforcing rib with surface on belt body, with corresponding connection anchor pole compared with large through-hole, can change loose band and shave structure, be suitable for many bars and share, entire combination supporting is strengthened.Although there is certain flexibility, allow country rock to produce a certain amount of distortion, limit again country rock and produce excessive distortion, to give full play to the self-supporting ability of country rock.But owing to only having the outstanding reinforcing rib with surface to contact with country rock, cause contact area little.After surrouding rock deformation produces crack, in the place of not contact, make broken surrounding rock produce excessive distortion, cause anchor pole to get loose or produce Lou rock whole supporting was lost efficacy.
Utility model content
The purpose of this utility model is exactly for overcoming above deficiency, and large, flexible large, the good stability of a kind of country rock contact area, anti-leak-stopping rock are provided, and can give full play to the OV shaped steel dish for anchoring of the self-supporting ability of country rock.
The technical solution of the utility model is achieved in that OV shaped steel dish for described anchoring, it is characterized in that arranging an oval steel disk body 1, in oval steel disk body 1, be provided with V-type steel plate 3 and make OV shaped steel dish-type, in OV shaped steel dish, be provided with and connect the through hole 2 that anchor pole is used.This OV shaped steel dish is that the method for bending, welding fabrication and pressure punching is manufactured.
The beneficial effects of the utility model are that, owing to having adopted such scheme, when having rock deformation pressure, OV shaped steel is checked and regulated body, under the effect of rock deformation pressure, shrinks.Now country rock moves to lane space, and country rock breaks, and the country rock volume after breaking increases.Meanwhile, thus because the rock of OV shaped steel after checking and regulating body and being close to country rock restriction and breaking produces excessive distortion, the rock breaking is tightly crowded together and is not caving, and so just from load, becomes structure, not only can support the pressure that oneself can also support overlying rock.That is to say the self-supporting ability of having given full play to country rock.Thereby reach large with country rock contact area, flexible large, anti-leak-stopping rock, can support large deformation and press, the object of performance country rock self-supporting ability.In structure, only on O shaped steel body, weld V-type steel plate and make OV type, and in OV type, have the through hole that connects anchor pole, simple in structure.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation
In figure: 1. oval steel disk body, 2. connects the through hole that anchor pole is used, 3.V shape steel plate.
The specific embodiment
Below in conjunction with drawings and Examples, to this use is novel, further illustrate.OV shaped steel dish for anchoring as shown in Figure 1, adopts the forming of method manufacture of steel plate bending, welding fabrication and pressure punching.Its structure is that an oval steel disk body 1 is set, and is provided with V-type steel plate 3 and makes OV shaped steel dish-type in oval steel disk body 1, is provided with and connects the through hole 2 that anchor pole is used in OV shaped steel dish.
Claims (1)
1. OV shaped steel dish for anchoring, it is characterized in that arranging an oval steel disk body (1), in oval steel disk body (1), be provided with V-type steel plate (3) and make OV shaped steel dish-type, in OV shaped steel dish, be provided with and connect the through hole (2) that anchor pole is used.
