Description

Technical Field

[0001] The utility model belongs to the technical field of land surveying, and particularly relates to a light-duty penetration instrument for detecting the bearing capacity of soil layers. Background Art

[0002] Soil bearing capacity refers to the maximum pressure that soil can withstand without becoming unstable when subjected to structural loads. Understanding the bearing capacity of soil is crucial to ensuring the safety of buildings and infrastructure. Therefore, during land surveys, a lightweight penetration tester is required to assess soil bearing capacity on-site. It estimates the soil's bearing capacity by measuring the soil's resistance.

[0003] The existing light-weight probe for detecting the bearing capacity of soil layers uses a bracket to set up the detection module at the position where measurement is required, and then the personnel firmly insert the fixing bolt on the bracket into the soil with the help of tools or feet. The detection module consists of a hammering device and a rod with a probe. The rod with the probe is driven into the soil by hammering, and the depth of the probe entering the soil is recorded to estimate the bearing capacity of the soil. However, in actual detection, when the fixing bolt on the bracket is firmly inserted into the soil with the help of tools or feet, in order to ensure the firmness of the connection between the bracket and the ground and avoid the bracket from tilting and falling when hammering the rod with the probe, the personnel need to step on it multiple times or hammer the fixing bolt with the help of tools, which requires a lot of time and energy for the personnel, increases the workload of the personnel, and is not conducive to personnel use. Utility Model Content

[0004] In view of this, the utility model addresses the deficiencies of the existing technology and provides a lightweight probe for detecting the bearing capacity of soil layers. When it needs to be fixed to the ground, the fixing bolts around it can be electrically controlled to be firmly inserted into the soil, so that the bracket can be quickly and stably fixed to the ground, reducing the time required for installation and fixing by personnel and alleviating the workload of personnel.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a light-weight sounding instrument for detecting the bearing capacity of soil layers, including a shell, a sliding rod is slidably provided on the lower side of the shell, a probe is provided at the bottom end of the sliding rod, a sliding sleeve is slidably provided on the upper side of the outer arc surface of the sliding rod, the outer arc surface of the sliding sleeve is slidably connected to the shell, a handle is provided at the top of the sliding sleeve, a hammer is provided on the lower side of the outer arc surface of the sliding sleeve, a hammer seat is provided on the upper side of the outer arc surface of the sliding rod, the hammer and the hammer seat are installed in cooperation, and a fixing module for fixing is also provided on the shell; the outer fixing sleeve of the handle is provided with symmetrically distributed rubber sleeves.

[0006] As a further improvement of the present invention, the fixing module includes mounting seats evenly arranged on the outer side surfaces of the shell, and symmetrically distributed rotating shafts are rotatably arranged inside the mounting seats.

[0011] Secondly, by controlling the operation of motor 1, the fixing bolt is driven downward into the soil, thereby increasing the fixing effect of the support leg.

[0012] Third, through the cooperation of motor 1 and motor 2, after the support legs drive the lower fixing bolts to insert into the soil towards each other, they move towards each other, controlling the fixing bolts to insert downward into deeper soil, so that the support legs can be quickly and stably fixed on the ground, reducing the time required for personnel to install and fix.

[0013] Fourthly, the rubber cover on the outside of the handle can enhance the gripping experience of the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1 、 2 As shown, it includes a shell 101, a slide rod 102 is slidably provided on the lower side of the shell 101, a probe 103 is provided at the bottom end of the slide rod 102, a sliding sleeve 104 is slidably provided on the upper side of the outer arc surface of the slide rod 102, the outer arc surface of the sliding sleeve 104 is slidably connected to the shell 101, a handle 105 is provided on the top of the sliding sleeve 104, a hammer body 107 is provided on the fixed sleeve on the lower side of the outer arc surface of the sliding sleeve 104, a hammer seat 108 is provided on the fixed sleeve on the upper side of the outer arc surface of the slide rod 102, the hammer body 107 and the hammer seat 108 are installed in coordination, and a fixing module for fixing is also provided on the shell 101.

[0022] like Figure 2 、 4As shown, the fixing module includes a mounting base 201 evenly arranged on the outer side of the shell 101, and the interior of the mounting base 201 is rotatably provided with symmetrically distributed rotating shafts 202, and the outer arc surface of the rotating shaft 202 is fixedly sleeved with a rotating frame 203, and the bottom ends of two vertically adjacent rotating frames 203 are respectively rotatably provided with support legs 204, and the lower sides of the support legs 204 are slidably provided with fixing bolts 205, and the mounting base 201 is also provided with a driving unit 1 for driving the rotating frame 203 to rotate, and the support legs 204 are also provided with a driving unit 2 for driving the fixing bolt 205 to move.

[0023] like Figure 2 、 3 As shown, the drive unit 1 includes a worm wheel fixedly mounted on the outer arc surface of the rotating shaft 202 on the lower side, and a worm 209 is rotatably arranged inside the mounting seat 201. The worm 209 is respectively engaged with the adjacent worm wheels. The mounting seat 201 is also provided with an electric control component 1 for driving the worm 209 to rotate; the electric control component 1 includes a motor seat 210 arranged on the outside of the mounting seat 201, and a motor 211 is provided inside the motor seat 210. The output shaft of the motor 211 is respectively fixed to the adjacent worm 209 through a coupling.

[0024] like Figure 2 、 3 As shown, the driving unit 2 includes a support 206 arranged inside the support leg 204, and an adjusting screw 207 is rotatably arranged on the lower surface of the support 206.

[0025] During use, by controlling the operation of motor 211, the output shaft of motor 211 drives the worm 209 connected thereto to rotate, and then the meshing relationship between the worm 209 and the worm wheel causes the worm wheel to drive the lower rotating shaft 202 to rotate, so that the rotating shaft 202 drives the rotating frame 203 connected thereto to rotate.

When a person lifts the handle 105, the rubber sleeves 106 on the outer side of the handle 105 can enhance the person's grip experience, making it easier for the person to better detect the bearing capacity of the soil layer.
