Description

Technical Field

[0001] The utility model relates to the technical field of engineering investigation, in particular to a protection device for a surveyor used in engineering investigation. Background Art

[0002] Civil engineering is a general term for the science and technology of building various types of engineering facilities. It refers to the materials and equipment used, and the technical activities such as survey, design, construction, maintenance, and repair carried out, as well as the objects of engineering construction. Engineering exploration is a very important part of civil engineering. It is a technical means to determine the basic characteristics and spatial distribution of subsurface soil, groundwater and adverse geological effects.

[0003] After searching, Chinese patent number CN210834270U is a device for engineering investigation. By setting a sampling mechanism, the soil is sampled and observed. The existing soil sampling method generally uses a traditional T-type sampler. The traditional sampler has a simple structure and is easy to transport and carry. However, it is difficult to sample hard soil. The traditional sampler cannot be extended or the extension length is short, and deeper soil samples cannot be obtained. At the same time, when taking out the soil from the sampler, the soil is generally pushed out by external force. Since the soil sticks to the inner wall of the sampler, it is inconvenient to take out the soil. Therefore, a protective device for a surveyor for engineering investigation is proposed to solve the above problems. Utility Model Content

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, A protection device for a survey instrument used in engineering surveys in this embodiment includes a fixed base 1. A protection structure 2 is provided on the top of the fixed base 1. A support frame 3 is fixedly installed on the top of the fixed base 1. A hydraulic cylinder 4 is fixedly installed on the top of the support frame 3. An installation pipe 5 is fixedly installed on the top of the fixed base 1. A motor box 6 is fixedly installed at the bottom of the hydraulic cylinder 4. A motor 7 is fixedly installed inside the motor box 6. A spiral blade shaft 8 is fixedly connected to the output shaft of the motor 7. A balance weight 9 is fixedly installed at the bottom of the motor box 6. Balance rods 10 are fixedly installed on both the left and right sides of the balance weight 9. A sampling pipe 11 is fixedly installed at the bottom of the balance weight 9. Four universal wheels 12 are movably installed at the bottom of the fixed base 1.

[0025] As Figure 1 and Figure 4 shown in the figure, the protection structure 2 includes a fixed shell 201, an electric telescopic rod 202, a support rod 203, a hinge seat 204, a perforated ear plate 205, a movable block 206 and a stabilizing cone 207. Two fixed shells 201 are fixedly installed on the top of the fixed base 1. Electric telescopic rods 202 are fixedly installed on the inner walls of one side of the two adjacent fixed shells 201. Support rods 203 are hinged on the opposite sides of the two electric telescopic rods 202. Two hinge seats 204 are fixedly installed on the top of the fixed base 1. Perforated ear plates 205 are provided on the front and back sides of the two hinge seats 204. Movable blocks 206 are fixedly installed on the opposite sides of the two groups of perforated ear plates 205. A number of stabilizing cones 207 are provided at the bottom of the movable block 206. Before sampling and surveying the soil, start the protection structure to fix the position of the survey instrument and make the sampling process stable to avoid errors.

[0026] As Figure 2 and Figure 3 shown in the figure, two clamping blocks 13 are fixedly installed on the rear side of the installation pipe 5. A sampling box 14 is slidably fitted between the two clamping blocks 13. The sampled soil enters the inside of the sampling box 14. Then, slide the sampling box 14 along the two clamping blocks 13 and remove the sampling box 14 for surveying.

[0027] As Figure 2 and Figure 3 shown in the figure, a spring is fixedly installed on the rear side of the sampling pipe 11. A baffle is fixedly installed at the top of the spring. After sampling is completed inside the sampling pipe 11, the sampling pipe 11 is driven upward by the hydraulic cylinder 4. The baffle is blocked by the connecting pipe, causing the spring to compress and the first through hole to be exposed.

[0028] As Figure 2 and Figure 3As shown, a first through hole is provided at the rear side of the sampling tube 11, and a connecting tube is fixedly connected to the inner wall at the rear side of the mounting tube 5. When the baffle is blocked by the connecting tube, the first through hole is connected to the connecting tube. The spiral blade shaft 8 continues to rotate, causing the soil to reach the inside of the connecting tube from the first through hole and then enter the inside of the sampling box 14.

[0029] As Figure 3 shown, the bottom of the connecting tube is in contact with the top of the baffle. Sliding grooves are provided on the inner walls of the left and right sides of the mounting tube 5. The two balance rods 10 are slidably connected to the two sliding grooves. When the motor 7 drives the spiral blade shaft 8 to rotate, the sampling tube 11 will vibrate. The two balance rods 10 are engaged and slide with the two sliding grooves, allowing the balance block 9 to control the sampling tube 11 to avoid shaking.

[0030] As Figure 1 and Figure 2 shown, a second through hole is provided at the top of the fixed base 1. The sampling tube 11 extends to the bottom of the fixed base 1 through the second through hole. When sampling the soil, the hydraulic cylinder 4 drives the sampling tube 11 to move downward through the second through hole. The sampling tube 11 passes through the fixed base 1 and samples the soil while moving.

[0031] During implementation, the operation is carried out according to the following steps:

[0032] 1) First, start the two electric telescopic rods 202 to move the two movable blocks 206 to the left and right sides;

[0033] 2) Then, the two groups of stabilizing cones 207 fix the movable blocks 206 above the soil;

[0034] 3) Then, start the hydraulic cylinder 4 and the motor 7 to lower the sampling tube 11 to sample the soil;

[0035] 4) Finally, the soil enters the connecting tube and reaches the inside of the sampling box 14. The sampling box 14 is removed for investigation.

[0036] In summary, for the detector protection device for engineering investigation, by setting the protection structure 2, when soil sampling is carried out, two electric telescopic rods 202 are activated. The two electric telescopic rods 202 move the support rod 203 to the left and right sides, causing the two movable blocks 206 to move to the left and right sides. At the same time, the two groups of perforated ear plates 205 rotate on the two hinge seats 204, so that the bottoms of the two movable blocks 206 contact the ground. At the same time, the two groups of stabilizing cones 207 extend into the soil to fix the two movable blocks 206, thereby ensuring the stability of the detector and protecting the detector from shaking. For the detector protection device for engineering investigation, by setting the motor 7, after the detector is fixed in a suitable position, the hydraulic cylinder 4 is activated. The hydraulic cylinder 4 moves the motor box 6 together with the balance weight 9 downward. At the same time, the motor 7 is activated. The motor 7 drives the spiral blade shaft 8 to rotate. The spiral blade shaft 8 rolls the soil into the sampling tube 11. Subsequently, the sampling tube 11 is moved upward so that the top of the baffle contacts the bottom of the connecting pipe, causing the spring to contract. The first through hole is connected to the connecting pipe, and the soil is conveyed from the connecting pipe to the inside of the sampling box 14. Subsequently, the sampling box 14 is removed for investigation, thereby completing the function of soil investigation.
