Abstract
The invention discloses a kind of anchor pole erosion control and allow pressure component and processing and using method, it comprises one section of section is horseshoe-shaped seamless steel pipe, seamless steel pipe length is greater than the width of its u-shaped cross-section, insert in seamless steel pipe length same with it and there is certain flexible curved plate, and be just in time at the bottom of the arc of curved plate at the bottom of horseshoe-shaped string, common composition composite component, the axis of symmetry of composite component is processed with bolthole.Add man-hour, one section of seamless pipe is forged into the shape of a hoof and heat treatment; The steel plate of length same with above-mentioned steel pipe fitting and one fixed width is cold-pressed into arc-shaped steel plate; Arc-shaped steel plate is loaded in seamless shape of a hoof steel pipe fitting with the form of structure of interference fit; The axis of symmetry of composite component bores bolthole.During use, be arranged between the damping nut of anchor pole and anchor rod pallet board, play and once allow pressure and secondary allow pressure effect, thus reach anchor pole erosion control and allow the effect of pressing.
Description
Technical field
The present invention relates to anchor pole, particularly relate to anchor rod member.
Background technology
At present, in coal mine underground bolt support, installation is needed to allow pressure component in order to control anchor stress change.Allow pressure component have perhaps various ways, but their laminated structure that allows can only make anchor pole simply allow pressure under usually stress condition, can all put on anchor pole when there is shock loading for the second time, anchor pole can be broken, and does not have the protective effect to anchor rod body.
Summary of the invention
The object of the invention is to design a kind of anchor pole erosion control and allow pressure component, anchor pole can be made to allow pressure, anchor pole impact-proof loading can be made again, realize allowing pressure and effective unification of erosion control, reach the object having protection effect anchor rod body under impact loading.
For achieving the above object, anchor pole erosion control provided by the invention allow pressure component structure be, it comprises one section of section is horseshoe-shaped seamless steel pipe, seamless steel pipe length is greater than the width of its u-shaped cross-section, insert in seamless steel pipe length same with it and there is certain flexible curved plate, and be just in time at the bottom of the arc of curved plate at the bottom of horseshoe-shaped string, a common composition composite component, the axis of symmetry of composite component is processed with bolthole.
Above-mentioned anchor pole erosion control allow pressure component processing method be:
The first step, intercept on the seamless pipe of one section of certain wall thickness, intercepted length should be greater than its diameter, the seamless pipe intercepted is forged into the shape of a hoof and heat treatment, becomes seamless shape of a hoof steel pipe fitting; What the wall thickness of seamless pipe should meet anchor pole allows pressure value;
Second step, is cold-pressed into arc-shaped steel plate by the steel plate of length same with above-mentioned steel pipe fitting and one fixed width; The thickness of arc-shaped steel plate should meet the shock loading value of anchor pole, and the arc bottom width degree of arc-shaped steel plate should match with the insied width of shape of a hoof steel pipe fitting, and meets the requirement of interference fit;
3rd step, loads arc-shaped steel plate in seamless shape of a hoof steel pipe fitting with the form of structure of interference fit, makes just in time to be at the bottom of the arc of arc-shaped steel plate at the bottom of the string of the seamless shape of a hoof steel pipe fitting during loading, a common composition composite component;
4th step, the axis of symmetry of composite component bores bolthole.
During use, be arranged between the damping nut of anchor pole and anchor rod pallet board.When usually stress, first the shape of a hoof cambered surface of composite component is allowing the internal strain of pressure scope allow pressure; when second time occur shock loading exceed allow pressure scope time; the steel plate arcwall face of composite component accepts surge; thus reach anchor pole erosion control allow pressure effect; available protecting effect is played to anchor rod body, makes anchor pole remain supporting intensity to roadway surrounding rock.
The present invention significantly can promote the ability of anchor pole resistance to deformation and antagonism impact stress, and can realize anchor pole secondary and allow pressure, improves the sensitivity of anchor rod system to impact stress response.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the embodiment of the present invention is further illustrated.
Fig. 1 is the front view of the embodiment of the present invention;
Fig. 2 is the top view of Fig. 1.
In figure: 1-seamless steel pipe part, 2-arc-shaped steel plate, 3-bolthole.
Detailed description of the invention:
As depicted in figs. 1 and 2, a kind of anchor pole erosion control allows pressure component, it comprises one section of section is horseshoe-shaped seamless steel pipe part 1, the length of seamless steel pipe part 1 is greater than the width of its u-shaped cross-section, insert in seamless steel pipe part 1 length same with it and there is certain flexible arc-shaped steel plate 2, and be just in time at the bottom of the arc of arc-shaped steel plate 2 at the bottom of horseshoe-shaped string, common composition composite component, the axis of symmetry of composite component is processed with bolthole 3, namely at the top of seamless steel pipe part 1, the bottom of bottom and arc-shaped steel plate 2 is processed with through bolthole 3.
Above-mentioned anchor pole erosion control allow pressure component processing method be:
The first step, the seamless pipe of certain wall thickness intercepts one section, and intercepted length should be greater than its diameter, the seamless pipe intercepted is forged into the shape of a hoof and heat treatment, becomes shape of a hoof seamless steel pipe part 1; What the wall thickness of seamless circular pipe fitting 1 should meet anchor pole allows pressure value;
Second step, is cold-pressed into arc-shaped steel plate 2 by with the steel plate of the same length of above-mentioned steel pipe fitting 1 and one fixed width; The thickness of arc-shaped steel plate 2 should meet the shock loading value of anchor pole, and the arc bottom width degree of arc-shaped steel plate 2 should match with the insied width of shape of a hoof seamless steel pipe part 1, and meets the requirement of interference fit;
3rd step, loads arc-shaped steel plate 2 in shape of a hoof seamless steel pipe part 1 with the form of structure of interference fit, makes just in time to be at the bottom of the arc of arc-shaped steel plate 2 at the bottom of the string of shape of a hoof seamless steel pipe part 1, a common composition composite component during loading;
4th step, the axis of symmetry of composite component bores bolthole 3.
