Abstract
The utility model discloses a loading device of a shield segment ring model test. The loading device comprises a segment ring model (1), a smooth circular ring (2), a fixing device (3), a rope (4), a pulley wheel (5) and a weight (6). The loading device is characterized in that the smooth circular ring (2) is fixed at the center of the segment ring model (1); the fixing device (3) is fixed on the inner side wall of the segment ring model (1); one end of the rope (4) is connected with the fixing device (3) and the other end of the rope (4) penetrates through the smooth circular ring (2) and the pulley wheel (5) respectively; and the weight (6) is mounted at the tail end of the rope (4). According to the loading device of the shield segment ring model test disclosed by the utility model, the simulation of actual uniformly distributed load of a shield tunnel segment ring is realized, and the size of the load is controllable, so that a test result can be more accurate.
Description
Technical field
The utility model relates to a kind of charger of shield duct piece ring model test, specifically relates to a kind of charger that can apply evenly load around the ring model of section of jurisdiction.
Background technology
The test that often uses a model in the mechanical property research of shield tunnel loop is carried out, and for the actual forced status of simulative tube loop accurately, choosing of load mode just seems very important.
Common load mode has following several at present:
The first load mode is that the section of jurisdiction ring model is fixed on the bottom support bracket, adopt counterweight vertically to load on model top, a counterweight is the one-level load, the angle of the application point of power and the line of circle ring center and vertical direction is about 30 °, the operation of this load mode is fairly simple, yet that shield tunnel is in is underground, and the existence of load is arranged around the ring of section of jurisdiction, this loading and actual conditions deviation are larger, certainly will exert an influence to test findings.
The second load mode adopts a plurality of load(ing) points of disposed outside, be distributed in model around, this load mode, the size of power is difficult to control, and the equipment such as milscale in the test have not had the space of arranging yet.
The section of jurisdiction ring is in underground, has native load, water ballast(ing), vibrations load etc. around it, and above dual mode all can't well be simulated the stress of actual shield duct piece, exists error larger.
Summary of the invention
The purpose of this utility model is to have overcome deficiency of the prior art, provides a kind of load to control, and relatively encircles simultaneously the charger of the shield duct piece model test of actual forced status near the section of jurisdiction.
In order to solve the problems of the technologies described above, the utility model is to be achieved through the following technical solutions:
A kind of charger of shield duct piece ring model test, comprise section of jurisdiction ring model, smooth annulus, stationary installation, rope, pulley, counterweight, it is characterized in that: described smooth annulus is fixed in the center of section of jurisdiction ring model, stationary installation is fixed on the madial wall of section of jurisdiction ring model, described rope one end links to each other with stationary installation, the other end passes respectively smooth annulus and pulley, and at its end counterweight is installed.
Described rope is provided with many, and the even circle distribution of a plurality of stationary installations of its correspondence is at the madial wall of section of jurisdiction ring model.
Compared with prior art, the beneficial effects of the utility model are:
Having realized that load is uniform is carried on the ring model of section of jurisdiction, more approaching with the actual forced status of shield tunnel loop, power on each root rope can be controlled, can calculate first the size of the power that every rope should apply, then each root rope is carried out counterweight and load, and can realize hierarchical loading.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, the utility model comprises section of jurisdiction ring model 1, smooth annulus 2, stationary installation 3, rope 4, pulley 5, counterweight 6.Smooth annulus 2 is fixed in the center of section of jurisdiction ring model 1, consists of concentric circles.Pulley 5 is fixed on the not far place of distance model.Stationary installation 3 is fixed on the madial wall of section of jurisdiction ring model 1.Rope 4 one ends link to each other with stationary installation 3, and the other end passes respectively smooth annulus 2 and pulley 5, and at its end counterweight 6 are installed.Described rope 4 is provided with many, and a plurality of stationary installations 3 even circle distribution of its correspondence are at the madial wall of section of jurisdiction ring model 1.The weight of the utility model counterweight can be controlled, be applied on the ring model of section of jurisdiction by the gravity of rope with counterweight, thereby realize the uniform loading of section of jurisdiction ring model, can also encrypt load(ing) point if needed, the load that this load mode produces and the actual forced status of shield duct piece ring are comparatively approaching, thereby make the result of model test more accurate.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.
Claims (2)
1. the charger of shield duct piece ring model test, comprise section of jurisdiction ring model (1), smooth annulus (2), stationary installation (3), rope (4), pulley (5), counterweight (6), it is characterized in that: described smooth annulus (2) is fixed in the center of section of jurisdiction ring model (1), stationary installation (3) is fixed on the madial wall of section of jurisdiction ring model (1), described rope (4) one ends link to each other with stationary installation (3), the other end passes respectively smooth annulus (2) and pulley (5), and at its end counterweight (6) is installed.
