Abstract
The utility model relates to a foundation bolt assembly which comprises screw threads, a ground anchor and a positioning plate. The ground anchor is fixed on the ground and provided with a threaded hole for nesting, a gasket, the positioning plate and a buffer pad are downward and sequentially fixed through the screw threads, and a limiting sleeve is arranged on the peripheral direction of the screw threads and connected with the positioning plate in a stepped mode. By adopting the technical scheme, the foundation bolt assembly can effectively prevent the screw threads from deforming and improve the stability.
Description
Technical field
The utility model relates to stone bolt technical field, is specifically related to a kind of stone bolt assembly.
Background technique
Stone bolt is for trapped orbit steel plate, the fixing bolt of main equipment, one is earth anchor, be fixed on underground, conventionally earth anchor is cast in ground, other end is screw screw thread, be fixed on equipment, conventionally in main equipment work, or when train passes through track, can produce strong vibration, stone bolt is subject to the stress of horizontal and vertical direction, at present, screw screw thread is by the spacing hole on positioning plate and earth anchorage, when main equipment or rail steel panel vibration are when larger, easily there is deformation in screw screw thread, cause stone bolt fixing unstable on equipment, accidents caused, make troubles to enterprise.
Model utility content
The purpose of this utility model is to provide a kind of stone bolt assembly that can effectively prevent the distortion of screw screw thread, strengthen stability.
To achieve these goals, the utility model provides a kind of stone bolt assembly, comprise screw screw thread, earth anchor and positioning plate, described earth anchorage is at the bottom of ground, on described earth anchor, offer the tapped hole of nested use, described screw screw thread is fixed with packing ring, positioning plate and cushion pad downwards successively, and described screw screw thread week is upwards provided with stop collar, and described stop collar becomes stepped joint with positioning plate joint.
Adopt the stone bolt assembly of technique scheme to have following advantage: in the time that main equipment running or train produce judder by track, stone bolt is subject to horizontal and vertical direction stress, Vertical direction is by the cushion pad longitudinally arranging, reduce the impact of vertical stress to stone bolt, upwards be provided with stop collar in screw screw thread week, positioning plate is subject to horizontal stress, first remake and be used on stone bolt by stop collar, make screw screw thread entirety stressed, strengthen the resistance ability of stone bolt, the setting of stop collar, also horizontal stress is played to buffer function, avoid stone bolt generation deformation, make bolt fixed structure stable.
As preferred version, consider that positioning plate is subject to horizontal stress, energy and stop collar effectively cushion, and described stop collar and positioning plate end face are in same plane.
As preferred version, consider that positioning plate is in the time being subject to vertical stress, cushion pad is buffering vertical stress effectively, avoid stone bolt to be subject to vertical stress effect, cause bolt to connect loosening, described cushion pad is nylon sheet, the nylon sheet of flexible plastic material, can effectively cushion vertical stress.
Accompanying drawing explanation
Fig. 1 is the utility model stone bolt assembly embodiment's structural representation;
Wherein: 1, screw screw thread, 2, earth anchor, 3, positioning plate, 4, packing ring, 5, cushion pad, 6, stop collar.
embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
As shown in Figure 1, the utility model provides a kind of stone bolt assembly, comprise screw screw thread 1, earth anchor 2 and positioning plate 3, earth anchor 2 is fixed on the end, ground, be fixed on underground by concreting, on earth anchor 2, offer the tapped hole of nested use, screw screw thread 1 forms locking structure by the tapped hole on earth anchor 2, screw screw thread 1 is fixed with packing ring 4, positioning plate 3 and cushion pad 5 downwards successively, screw screw thread is upwards provided with stop collar 6 for 1 week, stop collar 6 inwalls and the laminating of screw screw thread outer surface, stop collar 6 becomes stepped joint with positioning plate 3 joints; In addition, as preferred version, consider that positioning plate 3 is subject to horizontal stress, energy and stop collar 6 effectively cushion, and stop collar 6 and positioning plate 3 end faces are in same plane; As preferred version, consider that positioning plate 3 is in the time being subject to vertical stress, cushion pad 5 is buffering vertical stress effectively, avoid stone bolt to be subject to vertical stress effect, cause bolt to connect loosening, cushion pad 5 is nylon sheet, the nylon sheet of flexible plastic material, can effectively cushion vertical stress.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (3)
