Abstract
The invention discloses an anchor rod scour-prevention yielding component and a processing and usage method of the component. The component comprises a section of seamless steel tube, of which the section is in a horseshoe shape, the length of the seamless steel tube is larger than the width of the horseshoe-shaped section, an arc-shaped steel plate which has the same length as that of the seamless steel tube and has certain elasticity is arranged in the seamless steel tube, an arc bottom of the arc-shaped steel plate is arranged on a horseshoe-shaped chord bottom, a composite component is formed, and an anchor rod hole is processed on a symmetry axis of the composite component. During processing, a section of the seamless steel tube is forged and pressed into a horseshoe shape and subjected to heat processing; a steel plate with the same length as that of the steel tube part and a certain width is subjected to cold pressing to form an arc-shaped steel plate part, the arc-shaped steel plate part is embedded into the seamless horseshoe-shaped steel tube part in an interference fit structure mode, and the anchor rod hole is drilled on the symmetry axis of the composite component. During usage, the component is installed between a damping nut of the anchor rod and a tray of the anchor rod, and a primary yielding function and a secondary yielding function are achieved, so that scour-prevention yielding effects of the anchor rod are achieved.
Description
Technical field
The present invention relates to anchor pole, relate in particular to anchor rod member.
Background technology
At present, in the underground bolt support in colliery, need to install and to let the pressure member in order to control the anchor stress variation.Let and press member that many kinds of forms are arranged, but their laminated structure that lets can only make anchor pole simply let pressures under stress condition usually, when shock loading appears in the second time, can all put on the anchor pole, anchor pole can be broken, and does not have the protective effect to anchor rod body.
Summary of the invention
The objective of the invention is to design a kind of anchor pole erosion control and let the pressure member, can make anchor pole let pressure, can make anchor pole protecting against shock load again, realize letting and press the effective unification with erosion control, reaching has protection to imitate the purpose of anchor rod body under impact loading.
For achieving the above object; Anchor pole erosion control provided by the invention lets presses the structure of member to be, it comprises that one section section is horseshoe-shaped seamless steel pipe, and seamless steel pipe length is greater than the width of its u-shaped cross-section; Insert in the seamless steel pipe length same and have certain flexible curved plate with it; And on just in time being at the bottom of the horseshoe-shaped string at the bottom of the arc of curved plate, form a composite component jointly, on the axis of symmetry of composite component, be processed with bolthole.
Above-mentioned anchor pole erosion control lets presses the processing method of member to be:
The first step, on the seamless pipe of one section certain wall thickness of intercepting, intercepted length should be greater than its diameter, and the seamless pipe of intercepting is forged into the shape of a hoof and heat treatment, makes it become seamless shape of a hoof steel pipe fitting; What the wall thickness of seamless pipe should satisfy anchor pole lets the pressure value;
In second step, will be cold-pressed into curved plate spare with the steel plate of same length of above-mentioned steel pipe fitting and certain width; The thickness of curved plate spare should satisfy the shock loading value of anchor pole, and the arc bottom width degree of curved plate spare should match with the insied width of shape of a hoof steel pipe fitting, and satisfies the requirement of interference fit;
The 3rd step, curved plate spare is packed in the seamless shape of a hoof steel pipe fitting with the form of structure of interference fit, make at the bottom of the string that just in time is in seamless shape of a hoof steel pipe fitting at the bottom of the arc of curved plate spare when packing on, form a composite component jointly;
In the 4th step, boring bolthole on the axis of symmetry of composite component.
During use, it is installed between the damping nut and anchor pole pallet of anchor pole.The shape of a hoof cambered surface of composite component is at first letting the internal strain of pressure scope let pressure when stress usually; Exceed when letting the pressure scope when shock loading for the second time occurring; The steel plate arcwall face of composite component is accepted surge; Let the effect of pressing thereby reach the anchor pole erosion control, anchor rod body is played effective protective effect, make anchor pole remain supporting intensity roadway surrounding rock.
The present invention can significantly promote the ability of anchor pole resistance to deformation and antagonism impact stress, and can realize that the anchor pole secondary lets pressure, the sensitivity that has improved anchor rod system impact stress response.
Description of drawings:
Below in conjunction with accompanying drawing the embodiment of the invention is further specified.
Fig. 1 is the front view of the embodiment of the invention;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1-seamless steel pipe spare, 2-curved plate spare, 3-bolthole.
The specific embodiment:
As depicted in figs. 1 and 2; A kind of anchor pole erosion control lets the pressure member; It comprises that one section section is horseshoe-shaped seamless steel pipe spare 1, and the length of seamless steel pipe spare 1 is greater than the width of its u-shaped cross-section, insert in the seamless steel pipe spare 1 length same with it and have certain flexible curved plate spare 2; And on just in time being at the bottom of the horseshoe-shaped string at the bottom of the arc of curved plate spare 2; Common form a composite component, on the axis of symmetry of composite component, be processed with bolthole 3, promptly be processed with the bolthole 3 of perforation in the bottom of top, bottom and the curved plate spare 2 of seamless steel pipe spare 1.
Above-mentioned anchor pole erosion control lets presses the processing method of member to be:
The first step, intercepting is one section on the seamless pipe of certain wall thickness, and intercepted length should be greater than its diameter, and the seamless pipe of intercepting is forged into the shape of a hoof and heat treatment, makes it become shape of a hoof seamless steel pipe spare 1; What the wall thickness of seamless circular pipe fitting 1 should satisfy anchor pole lets the pressure value;
In second step, will be cold-pressed into curved plate spare 2 with the steel plate of above-mentioned steel pipe fitting 1 same length and certain width; The thickness of curved plate spare 2 should satisfy the shock loading value of anchor pole, and the arc bottom width degree of curved plate spare 2 should match with the insied width of shape of a hoof seamless steel pipe spare 1, and satisfies the requirement of interference fit;
The 3rd step, curved plate spare 2 is packed in the shape of a hoof seamless steel pipe spare 1 with the form of structure of interference fit, make at the bottom of the string that just in time is in shape of a hoof seamless steel pipe spare 1 at the bottom of the arc of curved plate spare 2 when packing on, form a composite component jointly;
