Connection structure for wheel shaft assemblies for angle sensor of wireless inclinometer and sleeve

Abstract

The invention discloses a connection structure for wheel shaft assemblies for an angle sensor of a wireless inclinometer and a sleeve. An upper wheel shaft assembly (A) is disposed right above a lower wheel shaft assembly (B). The upper wheel shaft assembly and the lower wheel shaft assembly are in the same structure. All the wheel shaft assemblies comprise wheel shafts (1). Elongated through holes (1a) are formed in shaft bodies of the wheel shafts (1) and internally provided with a wheel carrier (2). Two ends of the wheel carrier (2) stretch out of the peripheral side wall of each wheel shaft (1). End portions at two ends of the wheel carrier (2) are provided with rollers (3). A sleeve (7) is arranged between the upper wheel shaft assembly (A) and the lower wheel shaft assembly (B). The end opening of the sleeve (7) enables an end head of a corresponding wheel shaft (1) to be sleeved and fixed. The connection structure for the wheel shaft assemblies for the angle sensor of the wireless inclinometer and the sleeve has following beneficial effects: the connection structure is few in component, simple and compact in structure, small in size, convenient in assembly, fine in connection firmness and low in cost; the rollers rotate flexibility and do not oscillate; and the angle sensor can move more smoothly and reliably.

Description

technical field [0001] The invention relates to the field of engineering measurement, especially the field of space physics and geophysics, especially to monitoring the lateral displacement of landslide areas and excavated soil in deep tunnels, in particular to a wheel shaft assembly and a wireless inclinometer angle sensor Sleeve connection structure. Background technique [0002] The inclinometer is an in-situ detection instrument for measuring the lateral displacement of a borehole. It can be used in in-situ detection of geotechnical engineering in transportation, metallurgy, coal, water conservancy and hydropower departments, and urban construction departments, especially in slopes, It has irreplaceable superiority and practicability in the depth and lateral displacement detection of foundations, earth-rock dams and underground caverns. At present, most of the inclinometers on the market use multi-core cables to connect with the inclinometer probe. On the one hand, this...

Problems solved by technology

At present, most of the inclinometers on the market use multi-core cables to connect with the inclinometer probe. On the one hand, this connection plays the role of data communication, and on the other hand, it plays the role of supporting connection. When measuring and using, multi-core cables will break, which will increase the cost of testing

In addition, multi-core cables are bulky and increase in weight as the depth of measurement increases, making handling even more inconvenient
