Problems solved by technology

However, there is no direct shear instrument capable of performing direct shear tests on the rock and soil materials to be cut under different temperature conditions, so it is difficult to study the relationship between the shear performance of the rock and soil materials to be cut and the temperature conditions

Embodiment 2

[0079] See attached image 3 And attached Figure 4 , improve on the basis of the cutting device and the direct shearing instrument for geotechnical materials provided in the first embodiment of the present invention, in the cutting device and the direct shearing instrument for geotechnical materials provided in the embodiment of the present invention, the control terminal 17 and the heating The communication mode between the chips 15 is wireless communication, and the wireless communication is selected from one of Bluetooth technology, Wi-Fi, 4G, 3G, GPRS, and zigbee. In this case, there is no need to process the first through hole 29 on the upper shear box 9 or the lower shear box 3, nor need to process the second through hole 30 on the heat insulating member 18-19-20-21, and, The movement range of the control terminal 17 is larger, and the control of the heating sheet 15 can also be realized remotely.

Abstract

The invention discloses a cutting device and a geomaterial direct shear apparatus and belongs to the technical field of cutters. The cutting device comprises a first tongs, a second tongs, a force arm, a fixed part, a stepping driving mechanism and a temperature adjusting device, wherein an accommodating space is formed between the first tongs and the second tongs; a to-be-cut object is divided into a first part and a second part and accommodated in the accommodating space to ensure that the first part is clamped by the first tongs and the second part is clamped by the second tongs; the temperature adjusting device is used for adjusting the temperature in the accommodating space; one end of the force arm is fixedly connected at the right side of the first tongs and the other end of the force arm is propped against the fixed part; and the stepping driving mechanism is used for providing a rightward acting force to the second tongs. The geomaterial direct shear apparatus comprises the cutting device. The cutting device has the advantages that the temperature of the to-be-cut object per se can be adjusted and the experimental study is carried out without changing the environment temperature, so that the operation is convenient and much energy can be saved.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a cutting device and a direct shearing instrument for rock and soil materials. Background technique [0002] Most of the cutting devices used in the prior art are in the form of knives, which can only cut the object to be cut under ambient temperature conditions, and cannot set different temperature parameters by itself. During the experiment and on-site operation of the relationship between cutting objects, it is necessary to change the environment temperature. Due to the large environment range, when the temperature parameters are studied in this way, the environment needs to be heated or refrigerated. More energy is consumed. [0003] Specifically in the field of geotechnical engineering technology, the direct shear test is a common method for determining the shear strength of rock and soil. Usually, four samples are used to shear with horizontal shear force under diffe...
