Abstract
The middle of a bottom force transferring plate 1 of the present invention is provided with a jack installation seat 3 connected by a positioning pin 2. A middle hole of the jack installation seat 3 is provided with a shaft with a rocking handle 6, and a displacement meter regulating shaft 4 whose surface forms a convex wedge shape, and the exterior of the jack installation seat is provided with a jack 5 communicated with an oil pipe 10; a cambered force transferring plate 8 with a force transferring plate fixing nut 7 is connected to the top of the jack 5, and the inner wall of the cambered force transferring plate is in the shape of a rib; a displacement meter 9 is arranged in a hole of the force transferring plate 8; the other end of the displacement meter 9 contacts the displacement meter regulating shaft 4 in the shape of a convex mould, and the output end of the displacement meter 9 is connected with a signal wire. The present invention has the advantages of simple and compact structure, convenient operation, reliable data, good simulation factuality, etc.
Description
One, technical field
The present invention relates to a kind of tunnels mimic experimental rig, especially show it is internal loading actuator for analyzing stability of channel.
Two, background technology
Construction of tunnel is analyzed tunnel and adjoining rock stability simulated test in advance, will provide a kind of scientific basis to later engineering design, construction, operation.Have loading of the hollow body of employing and solid drill bit driving to load two kinds at present, but the former can only carry out static analysis, can not simulate digging process; And the latter can simulate the excavation form, but can't test weak points such as hole peripheral wall surfaces displacement.
Three, summary of the invention
But the purpose of this invention is to provide a kind of vertical, can be to the internal loading actuator for analyzing stability of channel of its inwall control loaded, unloading and testing tunnel inner wall deformation.
The object of the present invention is achieved like this, Bao Zhi has the microcomputer analysis system, vasculum, holding wire, pumping plant, stabilizator, oil pipe, the jack mount pad that part device connects with alignment pin in its end force transmitting board, jack mount pad mider hole is equipped with the surperficial displacement meter regulating shaft that is protruding wedge-like of axle of rocking handle, the jack that communicates with oil pipe is equipped with in the outside, the top of jack is connected with the force transmitting board that is circular arc of the inwall arc reinforcement shape of band force transmitting board hold-down nut, in the power transmission plate hole displacement meter is housed, the other end of displacement meter contacts with the displacement meter regulating shaft that is protruding wedge-like, and the displacement meter output line is connected with holding wire.
The present invention is by means of pumping plant, and stabilizator and oil pipe output oil pressure masterpiece are used for jack, along with stretching and stable state of jack controlled in the variation of oil pressure, simultaneously by loading, the unloading of force transmitting board realization to the tunnel inwall; Displacement meter is installed on the jack mount pad, its most advanced and sophisticated bulb stretches out contact tunnel inwall by the aperture of force transmitting board, the displacement meter afterbody displacement meter regulating shaft interior with being installed on the jack mount pad contacts by the outer rocking handle control displacement meter of rotation displacement meter regulating shaft flexible, vasculum, microcomputer analysis system that the final reading of displacement meter connects by holding wire, analyze the information of tunnel inner wall deformation, and can be stored in the computer.
Characteristics such as the present invention compared with prior art has simple and compact for structurely, easy for operation, and data are reliable, and the simulation authenticity is good.
Four, description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1-end force transmitting board 2-alignment pin 3-jack mount pad 4-displacement meter regulating shaft 5-jack 6-rocking handle 7-force transmitting board hold-down nut 8-force transmitting board 9-displacement meter 10-oil pipe 11-stabilizator 12-pumping plant 13-holding wire 14-vasculum 15-microcomputer analysis system
Five, the specific embodiment
As shown in drawings, force transmitting board 1 usefulness alignment pin 2 in the end is fixed with jack mount pad 3, the displacement meter regulating shaft 4 of band rocking handle 6 is housed in the jack mount pad 3, jack 5 is housed outward, jack 5 tops link with the force transmitting board 8 of band force transmitting board hold-down nut 7, force transmitting board 8 apertures are passed on displacement meter 9 tops, the lower end contacts with displacement meter regulating shaft 4, oil pipe 10 1 ends are connected with jack 5, the other end links to each other with stabilizator 11, pumping plant 12, and 13 1 of holding wires and displacement meter 9 output lines join, the other end joins with vasculum 14, microcomputer analysis system 15.
