Abstract
The invention discloses a device for testing pressure on the side wall of granular media. The device comprises an earth pressure cell (1) and a frame body (2) having a recessed cross section; edges (3) are arranged on two sides of the frame body (2); a plurality of through holes (4) are uniformly distributed on the frame body (2); the earth pressure cell (1) is sleeved in the through hole (4); a permanent magnet (6) is arranged on an inner wall (5) of the frame body (2); a cavity (7) is reserved between the permanent magnet (6) and the earth pressure cell (1); a lifting hole (8) is reserved on each edge (3). The device for testing the pressure on the side wall of the granular media has the advantages of simple structure, convenient use, excellent measuring effect, and accurate positioning.
Description
Technical field
The present invention relates to a kind of measurement mechanism, especially a kind of simple in structure, easy to operate, be mainly used in the proving installation that coal car, granary etc. are stored bulk material storing body sidewall pressure.
Background technology
In prose style free from parallelism experimental study, generally adopt soil pressure cell to be arranged under the material of certain depth and measure.But at the scene when in-situ test or shop experiment, a large amount of engineering practices show, how burying soil pressure cell underground can directly exert an influence to test result, when burying underground, the depth of burying is difficult to the location, and bury the destruction that improper meeting causes soil pressure cell and data line thereof underground, directly cause test result inaccurate.And the soil pressure cell that this mode is buried underground can't be tested for the prose style free from parallelism of mobile or height change, and can influence production, even the original structure of the equipment of destruction.
Summary of the invention
The present invention is in order to solve existing in prior technology the problems referred to above, to provide a kind of simple in structure, easy to use, and measurement effect is good, the device for testing pressure on side wall of granular media of accurate positioning.
Concrete solution of the present invention is: a kind of device for testing pressure on side wall of granular media, comprise that soil pressure cell 1 and cross section are the support body 2 of groove shape, the both sides of support body 2 are provided with edge 3, it is characterized in that: be evenly equipped with a plurality of through holes 4 at described support body 2, soil pressure cell 1 is socketed in the through hole 4, the inwall 5 of support body 2 is provided with permanent magnet 6, leaves cavity 7 between permanent magnet 6 and soil pressure cell 1, and 3 offer and lift hole 8 at the edge.
The present invention compares with prior art, has following advantage:
This device simple in structure, easy to use, can exactly soil pressure cell be positioned at desired height, and needn't worry that its height changes in the process of material of packing into, and then influence the accuracy of measurement data, and it is often destroyed to have solved in the traditional approach data line, the problem that surveying work can't be gone on; The measurement result of this device is accurate, can measure a prose style free from parallelism mobile or height change, possesses market outlook widely, very is conducive to apply in the art.
Description of drawings
Fig. 1 is front view of the present invention.
Fig. 2 is the cut-open view of A-A of the present invention portion.
Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.As shown in Figure 1 and Figure 2: a kind of device for testing pressure on side wall of granular media, comprise the soil pressure cell 1 for test prose style free from parallelism force value, described proving installation comprises support body 2, the cross section of support body 2 is the groove shape, is provided with edge 3 in the both sides of support body 2, is evenly equipped with a plurality of through holes 4 on the surface of support body 2, through hole 4 matches with the upper end of soil pressure cell 1, soil pressure cell 1 is socketed in the through hole 4 in use, and the inwall 5 of support body 2 is provided with permanent magnet 6, leaves cavity 7 between permanent magnet 6 and soil pressure cell 1; And 3 offer and lift hole 8 at the edge.
The course of work of the device for testing pressure on side wall of granular media of the embodiment of the invention is as follows: at first this proving installation is placed on the sidewall of prose style free from parallelism container, because inwall 5 is provided with permanent magnet 6, this proving installation just fixedly is adsorbed on the desired height of sidewall; 3 the hole 8 that lifts is installed with rope at the edge at this moment, so that test after finishing is taken out this proving installation; After the installation of this proving installation, in container, fill a prose style free from parallelism (as coal, cereal etc.), the soil pressure cell 1 that is socketed in the through hole 4 is just measured the force value of this prose style free from parallelism highly, and be transferred to by data line and be arranged on the outer display device of container, data line is embedded in the cavity 7, prevents that exposed data line is former thereby destroyed because of friction, collision etc.; After surveying work finishes, pull rope, this proving installation is pulled out from a prose style free from parallelism, wait for next time and using.
Claims (1)
1. device for testing pressure on side wall of granular media, comprise that soil pressure cell (1) and cross section are the support body (2) of groove shape, the both sides of support body (2) are provided with edge (3), it is characterized in that: be evenly equipped with a plurality of through holes (4) at described support body (2), soil pressure cell (1) is socketed in the through hole (4), the inwall (5) of support body (2) is provided with permanent magnet (6), leaves cavity (7) between permanent magnet (6) and soil pressure cell (1), and (3) offer and lift hole (8) at the edge.
