Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to an engineering detection device. Background Art

[0002] Engineering testing is an important means to ensure the safety of construction projects. It covers testing and evaluation of many aspects, from foundation to building materials, construction technology and building structure. In engineering construction, soil sampling and testing is an important part of ensuring the safety and stability of the project. Use a drilling rig to drill soil samples at the predetermined location, and then test the soil samples. By sampling and analyzing the particle composition, density, porosity, etc. of the soil, the bearing capacity and suitability of the soil can be determined. After soil sampling, standard penetration tests and unconfined compressive strength tests can be carried out to determine the bearing capacity of the soil and ensure that the foundation design of the building is reasonable to prevent settlement and deformation. Detecting the pH value, organic matter content and pollutant composition of the soil helps to evaluate the corrosiveness of the soil to building materials and the sustainability of the soil. During the construction process, regular soil sampling can monitor changes in soil properties, such as moisture changes, soil structure changes, etc., and adjust the construction plan in time to ensure the quality of the project.

[0003] For example, a Chinese invention patent with announcement number CN108318283B provides a soil sampler, which is placed vertically on the soil through a guide frame, and the guide frame is used to ensure the verticality of the sampling tube when it slides up and down and between the horizontal plane. However, when the sampler is sampling, due to the mechanical operation during sampling, the structure of the soil may be changed, resulting in compaction or disturbance of the sample, causing the inner and outer layers of the sample to be misaligned or squeezed, that is, the outer layer error of the sample is large, thereby reducing the authenticity of the sample. If the water content in the sampled soil is large, the water content in the soil will be lost during sampling, and it is impossible to accurately reflect the water content in the soil. And after the sample is taken out, because the sample is columnar as a whole, when the sample is separated from the sleeve, it will collapse and disperse when laid flat, resulting in changes in the structure of the sample. Summary of the invention

[0004] The invention provides an engineering detection device to solve the problem that when the existing detection device is sampling, the structure of the soil is changed and the water in the soil is lost, thereby resulting in low authenticity of the sample.

[0005] An engineering inspection device of the present invention adopts the following technical solution: an engineering inspection device includes a frame, a rotating drum, a first fixed drum, a collecting mechanism and an adjusting mechanism.

The first end of the separation bag is located outside the first fixed cylinder, and the second end of the separation bag bypasses the lower end of the first fixed cylinder and is located inside the first fixed cylinder. The part of the separation bag outside the first fixed cylinder is the first part, and the part of the separation bag inside the first fixed cylinder is the second part. The transmission assembly is used to drive the second end of the separation bag to move upward in the first fixed cylinder to increase the proportion of the second part of the separation bag to the whole separation bag.

[0008] In the initial state, the first rubber band and the second rubber band are outside the first fixed tube and are in an expanded state. When the first rubber band and the second rubber band enter the inside of the first fixed tube along with the separation bag, the first rubber band and the second rubber band contract and drive the separation bag at the connection between the first rubber band and the second rubber band to move closer to the middle of the first fixed tube, and the second rubber band and the plurality of first rubber bands separate the sample in the first fixed tube into several portions.

The first support ring, the first rubber band and the second support ring are sequentially distributed along the direction from the first end to the second end of the separation bag. In the initial state, the first support ring and the second support ring are on the outside of the first fixed cylinder. When the first support ring and the second support ring enter the inside of the first fixed cylinder with the separation bag, the first support ring and the second support ring are used to abut the inner wall of the separation bag of the second part and the first fixed cylinder.

[0010] Furthermore, the second adjustment component also includes a third support ring, which is fixedly connected to the separation bag. The third support ring is coaxially arranged with the first fixed cylinder, and the second rubber band and the third support ring are sequentially distributed along the direction from the first end to the second end of the separation bag. In the initial state, the third support ring is on the outside of the first fixed cylinder. When the third support ring enters the inside of the first fixed cylinder along with the separation bag, the third support ring is used to abut the inner wall of the separation bag of the second part and the first fixed cylinder.

[0011] Furthermore, the first support ring, the second support ring and the third support ring are all able to expand and contract to adapt to the difference in inner and outer diameters of the first fixed tube. The first support ring and the second support ring are both magnetic and magnetically attracted to each other. When the first support ring and the second support are outside the first fixed tube, the first part of the separation bag at the first support ring and the second support ring is wrinkled and folded.

[0012] Furthermore, the collecting mechanism also includes a connecting assembly, which includes a connecting frame and a fixing ring, wherein the connecting frame is slidably arranged in the first fixing tube, the fixing ring is fixedly arranged on the connecting frame, and the fixing ring and the first fixing tube are coaxially arranged.

The upper end of the lead screw is rotatably arranged in the nut, the lower end of the lead screw is rotatably connected to the connecting frame, and the lead screw and the connecting frame can move up and down synchronously. The forward rotation of the nut drives the lead screw to move upward. The first motor is fixedly arranged on the frame, and the belt connects the output shaft and the nut of the first motor.

[0014] Furthermore, an engineering detection device also includes a driving mechanism, the driving mechanism includes a second motor, the second motor is fixedly arranged on the frame, and a gear is fixedly arranged on the output shaft of the second motor. A gear ring is fixedly arranged on the rotating drum, and the gear ring is meshed with the gear.

[0015] Furthermore, a drill bit is provided on the lower end surface of the drum.

[0016] Furthermore, an engineering inspection device also includes a second fixed cylinder, which is arranged outside the first fixed cylinder, and the second fixed cylinder and the first fixed cylinder are arranged coaxially. The upper end of the second fixed cylinder is fixedly connected to the frame, and a stripping cone is fixedly arranged at the lower end of the second fixed cylinder. Along the direction from top to bottom, the radius of the stripping cone gradually decreases. The stripping cone is in the rotating cylinder, and the stripping cone is at the lower end of the first fixed cylinder. The diameter of the stripping cone is smaller than the diameter of the drill bit.

[0017] Furthermore, a handle is fixedly arranged on the frame.

[0018] The beneficial effects of the present invention are as follows: the engineering detection device of the present invention is in the first state when the adjustment mechanism is set to start working. The rotating drum rotates and moves deep into the soil. The frame moves downward and drives the first fixed drum and the second fixed drum to move downward synchronously. At the same time, the second end of the separation bag is driven to move upward through the transmission component to increase the proportion of the second part of the separation bag to the whole separation bag. At this time, the sample enters the separation bag in the first fixed drum.

[0019] As the separation bags on the outside of the first fixed cylinder enter the first fixed cylinder one after another. The adjustment unit at the bottom of the first fixed cylinder first enters the first fixed cylinder along with the separation bag. The first rubber band shrinks rapidly after entering the first fixed cylinder, and cuts the sample entering the first fixed cylinder. Multiple adjustment units enter the first fixed cylinder in turn, and multiple first rubber bands separate the sample into several axially equidistant parts. When the second rubber band enters the first fixed cylinder and cuts the sample, all sampling is completed. The sample is divided into several parts, so that the soil is layered, which is convenient for layered detection. Each sample is isolated by a separation bag to prevent water loss, which can truly reflect the moisture content of the soil. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 9 As shown, an engineering inspection device provided by an embodiment of the present invention includes a frame 100, a rotating drum 700, a first fixed drum 900, a collecting mechanism and an adjusting mechanism. The rotating drum 700 is vertically arranged, and the upper end of the rotating drum 700 is rotatably connected to the frame 100. The first fixed drum 900 is arranged in the rotating drum 700 and is coaxially arranged with the rotating drum 700. The upper end of the first fixed drum 900 is fixedly connected to the frame 100.

[0033] The collecting mechanism includes a separation bag 800 and a transmission assembly. The separation bag 800 is sleeved on the first fixed cylinder 900, and the two ends of the separation bag 800 are respectively a first end and a second end. The first end of the separation bag 800 is located outside the first fixed cylinder 900, and the second end of the separation bag 800 bypasses the lower end of the first fixed cylinder 900 and is located inside the first fixed cylinder 900. The part of the separation bag 800 outside the first fixed cylinder 900 is the first part, and the part of the separation bag 800 inside the first fixed cylinder 900 is the second part. The transmission assembly is used to drive the second end of the separation bag 800 to move upward in the first fixed cylinder 900 to increase the proportion of the second part of the separation bag 800 to the whole separation bag 800.

[0034] The adjustment mechanism includes a first adjustment component and a second adjustment component, and the second adjustment component and the first adjustment component are sequentially distributed along the direction from the first end to the second end of the partition bag 800. The first adjustment component includes a plurality of adjustment units, and the plurality of adjustment units are sequentially arranged along the vertical direction, and each adjustment unit includes a first rubber band 831. The second adjustment component includes a second rubber band 841, and the first rubber band 831 and the second rubber band 841 are both fixedly connected to the partition bag 800.

[0035] In the initial state, the first rubber band 831 and the second rubber band 841 are outside the first fixed cylinder 900 and are in an expanded state. When the first rubber band 831 and the second rubber band 841 enter the inner side of the first fixed cylinder 900 along with the separation bag 800, the first rubber band 831 and the second rubber band 841 contract and drive the separation bag 800 at the connection point of the first rubber band 831 and the second rubber band 841 to move closer to the middle of the first fixed cylinder 900. The second rubber band 841 and the plurality of first rubber bands 831 separate the sample in the first fixed cylinder 900 into several portions.

[0036] When the operation starts, the adjustment mechanism is located outside the first fixed cylinder 900. The rotating cylinder 700 rotates and moves deep into the soil. The frame 100 moves downward and drives the first fixed cylinder 900 and the second fixed cylinder 901 to move downward synchronously. At the same time, the second end of the separation bag 800 is driven upward by the transmission component to increase the proportion of the second part of the separation bag 800 to the entire separation bag 800. At this time, the sample enters the separation bag 800 in the first fixed cylinder 900.

[0037] As the separation bags 800 outside the first fixed cylinder 900 enter the first fixed cylinder 900 one after another. The adjustment unit at the bottom of the first fixed cylinder 900 first enters the first fixed cylinder 900 along with the separation bag 800. The first rubber band 831 shrinks rapidly after entering the first fixed cylinder 900, and drives the separation bag 800 at the connection of the first rubber band 831 to shrink, so as to cut the sample entering the first fixed cylinder 900. Multiple adjustment units enter the first fixed cylinder 900 in turn, and multiple first rubber bands 831 separate the sample into several axially equidistant parts. When the second rubber band 841 enters the first fixed cylinder 900 and cuts the sample, all sampling is completed. The sample is divided into several parts, so that the soil is layered, which is convenient for layered detection. Each sample is isolated by the separation bag 800 to prevent water loss, which can truly reflect the water content of the soil.

[0038] In this embodiment, each adjustment unit further includes a first support ring 830 and a second support ring 832 , both of which are fixedly connected to the separation bag 800 , and both of which are coaxially arranged with the first fixed cylinder 900 .

[0039] The first support ring 830, the first rubber band 831, and the second support ring 832 are sequentially distributed along the direction from the first end to the second end of the separation bag 800. In the initial state, the first support ring 830 and the second support ring 832 are located outside the first fixed cylinder 900. When the first support ring 830 and the second support ring 832 enter the inside of the first fixed cylinder 900 along with the separation bag 800, the first support ring 830 and the second support ring 832 are used to abut the inner wall of the second part of the separation bag 800 and the first fixed cylinder 900.

[0040] In this embodiment, the second adjustment component also includes a third support ring 840, the third support ring 840 is fixedly connected to the separation bag 800, and the third support ring 840 and the first fixed cylinder 900 are coaxially arranged. The second rubber band 841 and the third support ring 840 are sequentially distributed along the direction from the first end to the second end of the separation bag 800. In the initial state, the third support ring 840 is on the outside of the first fixed cylinder 900. When the third support ring 840 enters the inside of the first fixed cylinder 900 along with the separation bag 800, the third support ring 840 is used to abut the inner wall of the second part of the separation bag 800 and the first fixed cylinder 900.

[0041] In this embodiment, the first support ring 830, the second support ring 832 and the third support ring 840 are all able to expand and contract to adapt to the difference between the inner and outer diameters of the first fixed cylinder 900. The first support ring 830 and the second support ring 832 are both magnetic and magnetically attracted to each other, and the first portion of the separator bag 800 at the first support ring 830 and the second support ring 832 is folded.

[0042] Since the first support ring 830 and the second support ring 832 are magnetic, the first support ring 830, the second support ring 832 and the first rubber band 831 first move downward synchronously, and then the first support ring 830, the second support ring 832 and the first rubber band 831 synchronously cross the lower end of the first fixed cylinder 900. Afterwards, the first support ring 830, the second support ring 832 and the first rubber band 831 enter the inner side of the first fixed cylinder 900, and the first support ring 830 and the second support ring 832 and the inner wall of the first fixed cylinder 900 are against each other. Since the first rubber band 831 shrinks rapidly after being unsupported, it squeezes the separation bag 800 and cuts the secondary cylindrical sample. During operation, the first support ring 830 and the second support ring 832 always maintain magnetic attraction, so that the slit of the first rubber band 831 is small enough. When the first rubber band 831 shrinks, it drives the wrinkled and folded separation bag 800 to move toward the center of the first fixed cylinder 900 and gradually expands.

[0043] In this embodiment, the collection mechanism further includes a connection assembly, which includes a connection frame 810 and a fixing ring 820. The connection frame 810 is slidably disposed in the first fixing tube 900, and the fixing ring 820 is fixedly disposed on the connection frame 810. The fixing ring 820 and the first fixing tube 900 are coaxially disposed. The second part of the separation bag 800 is fixedly connected to the fixing ring 820.

[0044] In this embodiment, the transmission assembly includes a first motor 400, a belt 500, a lead screw 600 and a nut 601. The nut 601 is arranged on the frame 100, and the nut 601 and the first fixed cylinder 900 are coaxially arranged, and the nut 601 can rotate around its own axis. The lead screw 600 is arranged in the first fixed cylinder 900, and the lead screw 600 and the first fixed cylinder 900 are coaxially arranged. The upper end of the lead screw 600 is rotatably arranged in the nut 601, and the lower end of the lead screw 600 is rotatably connected to the connecting frame 810, and the lead screw 600 and the connecting frame 810 can move up and down synchronously. The forward rotation of the nut 601 drives the lead screw 600 to move upward. The first motor 400 is fixedly arranged on the frame 100, and the belt 500 connects the output shaft of the first motor 400 and the nut 601.

[0045] At the same time, the first motor 400 is started, and the first motor 400 drives the nut 601 to rotate forward through the belt 500, thereby driving the lead screw 600 to move upward. When the lead screw 600 moves upward, it drives the connecting frame 810 and the second end of the separation bag 800 to move upward synchronously.

[0046] In this embodiment, an engineering inspection device further includes a driving mechanism, which includes a second motor 200, the second motor 200 is fixedly disposed on the frame 100, and a gear 210 is fixedly disposed on the output shaft of the second motor 200. A gear ring is fixedly disposed on the rotating drum 700, and the gear ring is meshed with the gear 210. When the second motor 200 is started, the second motor 200 drives the gear 210 to rotate, and the gear 210 is meshed with the gear ring, thereby driving the rotating drum 700 to rotate.

[0047] In this embodiment, a drill bit 710 is disposed on the lower end surface of the rotating drum 700. When the rotating drum 700 rotates, the drill bit 710 is driven to rotate, and the drill bit 710 cuts the soil.

[0048] In this embodiment, an engineering inspection device further includes a second fixed cylinder 901, which is arranged outside the first fixed cylinder 900, and the second fixed cylinder 901 and the first fixed cylinder 900 are arranged coaxially. The upper end of the second fixed cylinder 901 is fixedly connected to the frame 100, and a stripping cone 902 is fixedly arranged at the lower end of the second fixed cylinder 901. Along the direction from top to bottom, the radius of the stripping cone 902 gradually decreases. The stripping cone 902 is in the rotating cylinder 700, and the stripping cone 902 is at the lower end of the first fixed cylinder 900. The diameter of the stripping cone 902 is smaller than the diameter of the drill bit 710, and the minimum diameter of the stripping cone 902 is equal to the diameter of the inner circle of the first fixed cylinder 900.

[0049] The drill bit 710 first cuts the soil to obtain an initial cylindrical sample. Since the diameter of the stripping cone 902 is smaller than that of the drill bit 710, the stripping cone 902 once again cuts off the surface layer on the side wall of the initial cylindrical sample to obtain a secondary cylindrical sample. The cut soil enters between the second fixed cylinder 901 and the rotating cylinder 700, so that the retained samples are samples that can more accurately reflect the soil conditions.

[0050] In this embodiment, a handle 300 is fixedly disposed on the frame 100 .

[0051] Working process: When starting to work, the adjustment mechanism is outside the first fixed cylinder 900. Start the second motor 200, the second motor 200 drives the gear 210 to rotate, the gear 210 and the gear ring are meshed, and then drives the rotating cylinder 700 to rotate, and the rotating cylinder 700 drives the drill bit 710 to rotate. Hold the handle 300 and drive the frame 100 to move downward, so that the rotating cylinder 700 rotates and moves deep into the soil.

[0052] The first fixed cylinder 900 and the second fixed cylinder 901 move downward synchronously with the frame 100. The drill bit 710 first cuts the soil to obtain an initial cylindrical sample. Since the diameter of the stripping cone 902 is smaller than the diameter of the drill bit 710, the stripping cone 902 once again cuts off the surface layer on the side wall of the initial cylindrical sample to obtain a secondary cylindrical sample. The cut soil enters between the second fixed cylinder 901 and the rotating cylinder 700, so that the samples retained are those that can more accurately reflect the soil conditions.

[0053] At the same time, the first motor 400 is started, and the first motor 400 drives the nut 601 to rotate forward through the belt 500, thereby driving the lead screw 600 to move upward. When the lead screw 600 moves upward, it drives the connecting frame 810 and the second end of the separation bag 800 to move upward synchronously. When the second end of the separation bag 800 moves upward, the part of the separation bag 800 outside the first fixed cylinder 900 is gradually moved to the inside of the first fixed cylinder 900, so as to increase the proportion of the second part of the separation bag 800 to the whole separation bag 800. At this time, the secondary cylindrical sample enters the separation bag 800 in the first fixed cylinder 900.

[0054] Then, the separation bag 800 outside the first fixed cylinder 900 enters the first fixed cylinder 900 one after another. The adjustment unit at the lower end of the outer side of the first fixed cylinder 900 first moves with the separation bag 800. Since the first support ring 830 and the second support ring 832 are magnetic, the first support ring 830, the second support ring 832 and the first rubber band 831 first move downward synchronously, and then the first support ring 830, the second support ring 832 and the first rubber band 831 synchronously cross the lower end of the first fixed cylinder 900. Afterwards, the first support ring 830, the second support ring 832 and the first rubber band 831 enter the inner side of the first fixed cylinder 900, and the first support ring 830 and the second support ring 832 abut against the inner wall of the first fixed cylinder 900. Since the first rubber band 831 shrinks rapidly after being unsupported, it drives the separation bag 800 to shrink, so as to cut the secondary cylindrical sample. When the first rubber band 831 contracts, the folded partition bag 800 is driven to move toward the center of the first fixing tube 900 and gradually expand.

[0055] After the first rubber band 831 cuts the secondary cylindrical sample, the sample between the fixing ring 820 and the second support ring 832 forms the first final cylindrical sample. Under the support of the fixing ring 820 and the second support ring 832, the first final cylindrical sample can maintain its basic shape and avoid deformation.

[0056] Then the next adjustment unit enters the first fixed cylinder 900, and the first rubber band 831 in the next adjustment unit continues to cut the secondary cylindrical sample. The first support ring 830 in the previous adjustment unit and the second support ring 832 in the next adjustment unit form a final cylindrical sample. Then multiple adjustment units enter the first fixed cylinder 900 in sequence, and multiple first rubber bands 831 successively separate the secondary cylindrical sample into a number of final cylindrical samples with equal axial distances.

[0057] Then, when the third support ring 840 and the second rubber band 841 enter the first fixed cylinder 900, the second rubber band 841 continues to cut the secondary cylindrical sample, and at this time, the first support ring 830 and the third support ring 840 in the last adjustment unit form the last final cylindrical sample. The soil is separated into a plurality of final cylindrical samples, so that the soil is layered, which is convenient for layered detection. Each final cylindrical sample is isolated by the separation bag 800 to prevent water loss, which can truly reflect the water content of the soil.
