Abstract
The utility model discloses a kind of hollow type bolt support structure, it comprises bolt body, adapter sleeve, spacing block set, steel band, pallet, spherical ball pad, packing ring, tray nut, spring, cone column sleeve and reinforces nut; Its reasonable in design, modern design is unique, simple to operate, easy to use, adopt between tray nut and pallet, increase spherical ball pad, can by spherical ball pad fine setting anchor pole in the position of vertical direction, steel band structural strength is large, the applying of anchor pole high pretightening force can be born, ensure supporting quality; And structure is simple, low cost of manufacture, prevents anchor pole exposed junction overlength by adapter sleeve and spacing block set, economic, practical.
Description
Technical field:
The utility model relates to anchor pole field, is specifically related to a kind of hollow type bolt support structure.
Background technology:
Along with the development of economic construction, as mine, tunnel etc. need the engineering of carrying out underground or massif excavation also increasing in Process of Engineering Construction, in these engineerings usually after shield machine is shaping, need to carry out safety support in case wall rock loosening, sillar come off to country rock; And in the supporting and protection structure of country rock, usually need to use support anchor rod, this anchor pole generally includes a set of compressing member of attacking the externally threaded body of rod in side and being arranged on the body of rod, and these compressing members comprise the pallet or joist that are socketed with the body of rod and spin with the body of rod and nut structure near external screw thread outer end; But the usual structure of existing anchor structure is simple, and anchor rod body, nut and pallet or joist section are all rigidly connected usually, and pallet or joist section just adopt the trapezoidal steel plate of single structure usually; When rock stratum occurs to loosen, anchor rod body partial feedback poor-performing, if anchor pole is screwed into slightly pine, it is easily caused to get loose from pallet or joist, if and screw portion is screwed into too tight, be very easy to cause pallet or joist easily rupture or are out of shape, and then cause Surrounding Rock Movement distortion to cause pretightning force to lose, make bolt portion lose anchored force because of lax, and the original built-up arch structure evenly closed also can be thinning or lost efficacy, cause bolt support failure.
Utility model content:
In order to solve the problem, the utility model provides a kind of technical scheme: a kind of hollow type bolt support structure, main body is bolt body, and its innovative point is: also comprise adapter sleeve, spacing block set, steel band, pallet, spherical ball pad, packing ring, tray nut, spring, cone column sleeve and reinforce nut; Described spacing block set is fixedly connected on the upper end outer round surface of bolt body; Described adapter sleeve is fixedly connected on the upper end of spacing block set; Described pallet is arranged on the outer round surface in the middle of bolt body; The upper end of described pallet is fixedly connected with steel band; The lower end of described pallet is fixedly connected with spherical ball pad; The lower end of described spherical ball pad is provided with packing ring; Described packing ring lower end is provided with tray nut; Described tray nut lower end is provided with spring; Described lower spring end is provided with cone column sleeve; Described cone column sleeve lower end is provided with reinforcing nut.
As preferably, described spring is disk spring.
As preferably, the external surface of described cone column sleeve and reinforce the inner surface phase profiling of nut.
As preferably, the soffit of described pallet and the upper surface of spherical ball pad are arc surface.
The beneficial effects of the utility model: its reasonable in design, modern design is unique, simple to operate, easy to use, adopt between tray nut and pallet, increase spherical ball pad, can by spherical ball pad fine setting anchor pole in the position of vertical direction, steel band structural strength is large, the applying of anchor pole high pretightening force can be born, ensure supporting quality; And structure is simple, low cost of manufacture, prevents anchor pole exposed junction overlength by adapter sleeve and spacing block set, economic, practical.
