Soil-based strength detection device

Abstract

The invention relates to the technical field of soil-based strength detection equipment, in particular to a soil-based strength detection device which comprises a first support, a supporting structure, a rotating structure, a levelness adjusting structure, a lubricating structure and a cleaning structure. The first support and the supporting structure are connected in a clamped mode, so that the first support and the supporting structure are more convenient and faster to mount and dismount, meanwhile, the first support and the supporting structure are connected more stably, and the firmness between the first support and the supporting structure is improved; the rotating structure serving as a lever fulcrum of a beam levex deflectometer is connected with the supporting structure in a clamped way, so that the rotating structure and the supporting structure are more convenient and faster to mount and dismount, and the rotating effect of the rotating structure is better; the thread position of the levelness adjusting structure is not exposed, then the situation that levelness adjustment is affected due to the fact that dust and scraps block the thread position is effectively prevented,and meanwhile the levelness adjusting structure can be lubricated every time the levelness adjusting structure is adjusted through cooperation with the lubricating structure.

Description

technical field [0001] The invention relates to the technical field of soil foundation strength detection equipment, in particular to a soil foundation strength detection device. Background technique [0002] The Beckman deflection meter is also called the lever deflection meter or the Beckman beam for short; it is an instrument for measuring the rebound deflection value of the road surface under the action of the vehicle load; it can also be used for the rebound deflection value of the entire soil foundation and the base; the main component is a A lever with a length ratio of 2:1 between the forearm and the rear arm at the root fulcrum; when measuring, insert the side of the forearm into the middle of a set of double tires on the rear axle of a car with a specified load, and record the percentage mounted on the end of the rear arm After the car moves forward and leaves the deflection influence radius, write down the dial gauge reading, and multiply the difference between th...

Problems solved by technology

[0003] However, the traditional Beckmann deflection instrument is composed of two or more sections of brackets. The joints of the brackets are connected by at least three bolts. The large axial pressure will easily cause damage to the bolts. The connecting shaft between the base and the bracket is also spliced ​​with bolts, which is inefficient in installation and disassembly. If the bolts are used for connection, when the tightness of the bolts is not adjusted properly, it is easy to cause a slight gap between the bracket and the base. At the same time, during the construction process, dust and debris are easy to stick to the connection between the base and the bracket, causing the connecting shaft to jam, which affects the efficiency of detection. At the same time, the level of the base is adjusted by bolts, and the thread is easy to accumulate dust , affecting the flexibility of the operation
