Description

Technical Field

[0001] The utility model relates to the technical field of sampling for project supervision, in particular to a sampling device for project supervision. Background Technique

[0002] Project supervision means that a supervision unit with relevant qualifications is entrusted by Party A. According to the contract, design documents and relevant standards, the construction quality of the project is comprehensively monitored to ensure that the project quality meets the design requirements and specifications. When conducting project supervision, a sampling device is usually used for sampling and testing for subsequent testing and analysis. It provides reliable data support for project quality supervision through scientific sampling methods and accurate sampling operations. When using the sampling device for project supervision, it is usually necessary to first determine the sampling position, then install the sampling device and perform the sampling operation, and finally process the sampled samples.

[0003] For example, the Chinese patent "A Sampling Device for Project Supervision" with the publication number CN210513749U includes a first sleeve, a screw conveyor assembly, a pointed head, a lead screw, a handwheel and a threaded sleeve; a threaded sleeve is arranged at the front part of the inner cavity of the first sleeve, the lead screw is sleeved with the threaded sleeve, and one end of the lead screw is fixedly connected with the handwheel, and the other end is fixedly connected with the screw conveyor assembly; the screw conveyor assembly is arranged at the rear part of the inner cavity of the sleeve and is fixedly connected with the pointed head at the end, and the outer diameter of the large end of the pointed head is smaller than the inner diameter of the first sleeve; a sample outlet is arranged at the lower bottom of the first sleeve, the screw conveyor assembly includes a rotating shaft and screw blades arranged on the rotating shaft, a handle is arranged at the upper part of the first sleeve, the pointed head is detachably and fixedly connected with the screw conveyor assembly, a sample collection bag is sleeved at the sample outlet, and the rotating shaft, the screw blades and the pointed head are all made of stainless steel materials.

[0004] Although the above-mentioned prior art can achieve sampling for project supervision, in actual use, on the one hand, the sampling effect of the sampling device is not good enough. Usually, the operator rotates the sampling rod, and the sampling is carried out through the screw blades on the sampling rod, resulting in difficulty for the sampling rod to penetrate into a relatively hard sampling surface, thus reducing the sampling efficiency. On the other hand, the sampling device is prone to position deviation. The vibration generated by the internal mechanical work of the sampling device will be transmitted to the sleeve, resulting in the vibration driving the sampling rod to deviate from its position, thus affecting the accuracy of the sample. Therefore, it does not meet the existing requirements. For this reason, we propose a sampling device for project supervision. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sampling device for project supervision to solve the problems of poor sampling effect of the sampling device and easy position deviation of the sampling device mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A sampling device for engineering supervision, including a sleeve. At the middle position inside the sleeve, a sampling cylinder is provided. The sampling cylinder is slidably matched with the sleeve, and the lower end of the sampling cylinder extends below the sleeve. On both sides inside the sleeve, telescopic grooves are provided. The telescopic grooves are of an open structure. On both sides of the sampling cylinder, fixing plates are fixedly provided. The fixing plates extend outside the sleeve. At the upper end of the sleeve, a mounting plate is fixedly provided. On both sides of the upper end of the mounting plate, hydraulic telescopic devices are fixedly provided. The telescopic ends of the hydraulic telescopic devices extend below the mounting plate and are fixedly connected to the fixing plates. Outside the sampling cylinder below the fixing plate, a discharge pipe is fixedly provided. The discharge pipe is communicated with the sampling cylinder.

[0007] Preferably, a rotating rod is provided inside the sampling cylinder. The rotating rod is rotatably connected to the upper end surface inside the sampling cylinder. On the outer part of the rotating rod, spiral blades are fixedly provided. At the upper end of the sampling cylinder located inside the sleeve, a motor is fixedly provided. The output shaft of the motor extends inside the sampling cylinder and is fixedly connected to the rotating rod.

[0008] Preferably, bases are provided at the front and rear ends outside the sleeve. Inside the bases near the sleeve side, fixing cavities are provided. The fixing cavities are of an open structure. At the front and rear ends outside the sleeve, connecting plates are fixedly provided. One end of the connecting plates extends inside the fixing cavities.

[0009] Preferably, at the lower end of the connecting plate located inside the fixing cavity, a damper is fixedly provided. The fixed end of the damper is fixedly connected to the inner wall of the fixing cavity. Between the fixed end and the telescopic end of the damper, a support spring is fixedly provided.

[0010] Preferably, scale lines are provided outside the sleeve at the opening side of the telescopic groove. The scale lines are flush with the lower end of the fixing plate.

[0011] Preferably, bolts are provided at the upper ends of the bases on the side of the fixing cavities. The bolts are threadedly connected to the bases, and the lower ends of the bolts extend into the sampling surface.

[0012] Preferably, a handle is fixedly provided at the middle position of the upper end of the mounting plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. The utility model can make the sampling device sample more easily through the hydraulic telescopic device and the motor. Before sampling, place the sampling device on the sampling surface and then fix the base through bolts. At this time, turn on the motor and the hydraulic telescopic device. The output shaft of the motor drives the rotating rod to rotate, and at the same time, the rotating rod rotates the external spiral blade together. The sampling surface is loosened by the spiral blade. At the same time, the telescopic end of the hydraulic telescopic device extends, and the sampling cylinder is pushed into the sampling surface by the extension of the telescopic end of the hydraulic telescopic device. At this time, during the rotation of the spiral blade, the sample is lifted upward and discharged from the sampling cylinder through the discharge pipe. At this time, the operator detects the discharged sample, thereby improving the power of the sampling device.

[0015] 2. The utility model can keep the sleeve stable through the damper and the connecting plate. When sampling, during the process of the motor and the hydraulic telescopic device pushing the fixing plate downward, vibration is likely to occur. At this time, the vibration is transmitted to the sleeve through the sampling cylinder, and the vibration on the sleeve is transmitted to the connecting plate. The connecting plate squeezes the damper due to the vibration. At this time, the damper undergoes compressive deformation, and the vibration is absorbed through the compressive deformation of the damper and the support spring. When sampling is completed, the damper and the support spring are reset. During the reset process of the damper and the support spring, the absorbed energy is released and the connecting plate is pushed back to its original position, preventing the vibration from being directly transmitted to the base, thereby maintaining the stability of the sampling rod during sampling.

[0016] 3. The utility model can display the sampling depth in real time by setting scale lines. When sampling, the fixing plate and the sampling cylinder move downward together. At this time, the sampling cylinder enters the sampling surface. During the downward movement of the fixing plate, it always remains horizontal with the scale line. At this time, the operator observes the position of the fixing plate on the scale line until the fixing plate is adjusted to the appropriate position. At this time, the scale line flush with the lower end of the fixing plate is the insertion depth of the sampling cylinder, which is convenient for the operator to observe the sampling depth of the sampling cylinder in real time, thereby improving the efficiency of the sampling operation.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Please refer to Figures 1-4 , an embodiment provided by the present invention: A sampling device for project supervision, including a sleeve 1. A sampling cylinder 2 is arranged at the middle position inside the sleeve 1. The sampling cylinder 2 is slidably matched with the sleeve 1. The lower end of the sampling cylinder 2 extends below the sleeve 1. Telescopic grooves 6 are arranged on both sides inside the sleeve 1. The telescopic grooves 6 are of an open structure. Fixed plates 5 are fixedly arranged on both sides of the sampling cylinder 2. The fixed plates 5 extend outside the sleeve 1. A mounting plate 3 is fixedly arranged at the upper end of the sleeve 1. Hydraulic telescopic devices 4 are fixedly arranged on both sides of the upper end of the mounting plate 3. The telescopic ends of the hydraulic telescopic devices 4 extend below the mounting plate 3 and are fixedly connected to the fixed plates 5. A discharge pipe 7 is fixedly arranged outside the sampling cylinder 2 below the fixed plate 5. The discharge pipe 7 is communicated with the sampling cylinder 2.

[0024] During use, before sampling, place the sampling device on the sampling surface, and then fix the base 9 through the bolts 10. At this time, turn on the motor 13 and the hydraulic telescopic device 4. The output shaft of the motor 13 drives the rotating rod 14 to rotate. At the same time, the rotating rod 14 rotates the external spiral blade 15 together. The sampling surface is loosened by the spiral blade 15. At the same time, the telescopic end of the hydraulic telescopic device 4 extends. The extension of the telescopic end of the hydraulic telescopic device 4 pushes the sampling cylinder 2 into the sampling surface. At this time, during the rotation of the spiral blade 15, the sample is lifted upward and discharged from the sampling cylinder 2 through the discharge pipe 7. At this time, the operator detects the discharged sample.

[0025] Please refer to Figure 2 and Figure 3 , a rotating rod 14 is arranged inside the sampling cylinder 2. The rotating rod 14 is rotatably connected to the upper end surface inside the sampling cylinder 2. A spiral blade 15 is fixedly arranged on the outside of the rotating rod 14. A motor 13 is fixedly arranged at the upper end of the sampling cylinder 2 inside the sleeve 1. The output shaft of the motor 13 extends into the sampling cylinder 2 and is fixedly connected to the rotating rod 14, which is convenient for driving the rotating rod 14 to rotate through the motor 13.

[0026] Please refer to Figure 1 and Figure 3 At both the front and rear ends outside the sleeve 1, there are bases 9 provided. Inside the base 9 near the side of the sleeve 1, there is a fixed cavity 12. The fixed cavity 12 is an open structure. At both the front and rear ends outside the sleeve 1, connecting plates 11 are fixedly arranged. One end of the connecting plate 11 extends into the interior of the fixed cavity 12, facilitating the installation of the damper 17 and the connecting plate 11 through the fixed cavity 12.

[0027] Please refer to Figure 3 and Figure 4 At the lower end of the connecting plate 11 located inside the fixed cavity 12, a damper 17 is fixedly arranged. The fixed end of the damper 17 is fixedly connected to the inner wall of the fixed cavity 12. Between the fixed end and the telescopic end of the damper 17, a support spring 18 is fixedly arranged, facilitating the absorption of vibrations generated during the operation of the sampling device through the damper 17.

[0028] Please refer to Figure 1 Outside the sleeve 1 on the side of the opening of the telescopic groove 6, there is a scale line 8. The scale line 8 is flush with the lower end of the fixing plate 5, facilitating the real-time display of the depth of the sampling cylinder 2 through the scale line 8.

[0029] Please refer to Figure 1 and Figure 3 On the upper end of the base 9 on the side of the fixed cavity 12, there is a bolt 10. The bolt 10 is threadedly connected to the base 9, and the lower end of the bolt 10 extends into the sampling surface, facilitating the fixation of the base 9 through the bolt 10.

[0030] Please refer to Figure 1 At the middle position of the upper end of the mounting plate 3, a handle 16 is fixedly arranged, facilitating the more convenient handling of the sampling device through the handle 16.

[0031] Working principle: When sampling, during the process of the motor 13 and the hydraulic telescopic device 4 pushing the fixing plate 5 downward, vibrations are likely to occur. At this time, the vibrations are transmitted from the sampling cylinder 2 to the sleeve 1, and the vibrations on the sleeve 1 are transmitted to the connecting plate 11. The connecting plate 11 squeezes the damper 17 due to the vibrations. At this time, the damper 17 undergoes compressive deformation, and the vibrations are absorbed through the compressive deformations of the damper 17 and the support spring 18. When the sampling is completed, the damper 17 and the support spring 18 return to their original positions. During the process of the damper 17 and the support spring 18 returning to their original positions, the absorbed energy is released and the connecting plate 11 is pushed back to its original position. When sampling, the fixing plate 5 and the sampling cylinder 2 move downward together. At this time, the sampling cylinder 2 enters the sampling surface. During the process of the fixing plate 5 moving downward, it always remains horizontal with the scale line 8. At this time, the operator observes the position of the fixing plate 5 on the scale line 8 until the fixing plate 5 is adjusted to the appropriate position. At this time, the scale line 8 flush with the lower end of the fixing plate 5 is the insertion depth of the sampling cylinder 2.
