Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically a concrete sampling mechanism. Background Technology

[0002] Concrete is an engineering composite material that binds aggregates together with cementing materials. Concrete is mainly composed of cement, water, sand and gravel. Concrete has a wide range of applications in the construction field, including the construction of houses, apartments, buildings, shops, schools and other buildings. In order to ensure the quality of concrete and the stability of construction quality, it is necessary to sample and test the concrete. At present, there are various concrete sampling agencies available on the market, but there are still some shortcomings.

[0003] Existing concrete sampling mechanisms cannot be quickly detached from the supporting bracket after sampling through the sampling tube, which affects subsequent testing. Furthermore, the lack of a shielding device below the sampling head after the concrete sample enters the sampling tube can cause the sample to slip out of the tube. For example, Chinese utility model patent CN220084390U discloses a concrete sampling mechanism in which a transmission sleeve is slidably sleeved at the middle of the outer side of a hollow tube. Transmission rods are hinged to the middle of both sides of the bottom of the transmission sleeve via rotating shafts. Each transmission rod has a connecting frame hinged to its bottom via a rotating shaft. A fixing rod is fixedly installed on both ends of the outer side of each hollow sealing frame, and the fixing rod is rotatably mounted inside the connecting frame. An adjusting bolt is threaded onto the inner side of the top of the hollow tube, and a push plate is slidably installed inside the hollow tube. The bottom of the adjusting bolt is rotatably mounted inside the middle of the push plate via a bearing. This invention utilizes a transmission rod to allow the operator to quickly rotate and adjust two sets of hollow sealing frames, enabling them to grip and collect the concrete to be tested. This facilitates rapid concrete sampling and improves subsequent concrete testing efficiency. However, this mechanism requires manual handling during sampling, which can lead to displacement and affect sampling efficiency. Therefore, we propose a concrete sampling mechanism to address these issues. Summary of the Invention

[0004] The purpose of this utility model is to provide a concrete sampling mechanism to solve the problems of the current concrete sampling mechanisms mentioned in the background art, such as the inability to quickly detach the sampling cylinder from the support, which affects the subsequent testing of concrete, the possibility of the sampling head slipping after the concrete is sampled, and the need for manual handling to sample concrete, which can lead to positional shifts during the sampling process and affect sampling efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete sampling mechanism, comprising:

[0006] A sampling tube, wherein a connecting ring is slidably connected to the outer side of the sampling tube;

[0007] Also includes:

[0008] The outer side of the connecting ring is provided with a disassembly mechanism, which includes a mounting block, a locking rod, a slot and a connecting block. The mounting blocks are fixedly installed symmetrically on the outer side of the connecting ring, and the connecting block is tightly fitted inside the mounting block. The mounting block and the connecting block are engaged with a locking rod inside, and a slot is opened inside the upper part of the connecting block.

[0009] A support mechanism is provided on the outside of the connecting block. The support mechanism includes a support frame, a support column, a fixed cone, a protective box, bolts, and a connecting rod. The support frame is slidably connected to the outside of the connecting block, and a support column is fixedly installed below the support frame. A fixed cone is installed in an array below the support column.

[0010] Preferably, a locking rod is engaged with the front side of the slot.

[0011] Preferably, a spring is fixedly connected to the top of the connecting block, and the top of the spring is fixedly connected to the upper interior of the support frame.

[0012] Preferably, a handle is provided on the top of the support frame.

[0013] Preferably, the sampling tube has grooves on the upper interior left and right sides, and a push shaft is slidably arranged in the middle of the sampling tube, with a push plate installed at the lower end of the push shaft.

[0014] Preferably, shielding boxes are symmetrically arranged on the front and rear sides below the sampling tube, and fixing blocks are symmetrically fixed on the left and right sides of the outer side of the shielding boxes.

[0015] Preferably, the internal threaded connection of the fixing block is a limiting threaded rod.

[0016] Preferably, a protective box is provided on the outer side of the fixed cone, and the upper interior of the protective box is in close contact with the outer side of the support column.

[0017] Preferably, the protective box and the support column are fixedly connected by bolts.

[0018] Preferably, a connecting rod is fixedly installed on the rear side of the support column.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: the concrete sampling mechanism is designed with a disassembly mechanism, which allows the sampling tube and the support to be quickly separated, providing convenience for subsequent concrete testing. At the same time, a shielding mechanism is set up with a shielding cover on the lower outer side of the sampling tube, which can effectively prevent concrete from slipping out of the sampling tube. In addition, a support mechanism is set up with the support to improve the stability of the sampling tube during sampling and greatly improve the sampling efficiency.

[0020] The device is equipped with a connecting ring, mounting block, locking rod, and locking groove. The connecting ring is slidably connected to the outside of the sampling cylinder, and the mounting blocks are fixedly installed on the left and right sides of the outside of the connecting ring. The inside of the mounting block is tightly fitted with the connecting block set on the inside of the support frame. At the same time, the mounting block and the connecting block are locked together by the locking rod. The upper inner side of the locking rod is locked together with the locking groove opened inside the upper part of the connecting block. That is, simply pulling the locking rod forward will cause the mounting block and the connecting block to separate, and the sampling cylinder can be removed from the mechanism.

[0021] Equipped with a spring, support frame, and handle slot, the sampling tube is supported on the outside of the connecting block, and a spring is installed on top of the connecting block. The spring is connected to the support frame. The spring has elasticity, meaning that by gripping the handle slots on the left and right sides of the top of the sampling tube, the sampling tube can be pushed downwards. The sampling tube is hollow, meaning that as the sampling tube moves downwards, it will come into contact with and be squeezed by the concrete. The concrete can enter the interior of the sampling tube through the bottom. Since the sampling tube and the connecting ring are rotatably connected, the sampling tube can also be rotated appropriately to make it sample faster. After sampling, the handle slot can be released, and the sampling tube will rebound due to the elasticity of the spring.

[0022] The system is equipped with a support frame, support column, fixed cone, and connecting rod. The support column is fixedly installed below the support frame, and the fixed cone is installed below the support column. When the equipment needs to be used, the protective box on the outside of the fixed cone can be removed first, and then the fixed cone can be inserted into the ground. At this time, the bottom of the support column and the connecting rod installed on the back of the support column will fit tightly with the ground, which can firmly fix and support the mechanism. When the worker pushes the sampling tube downward, he can also step on the connecting rod with his shoe, which can further improve the stability of the mechanism during sampling.

[0023] The device is equipped with a protective box and bolts. The protective box is installed on the outside of the fixed cone and is fixedly connected to the fixed cone by bolts. The protective box can protect the fixed cone when the device is not in use and can prevent workers from accidentally touching it and getting injured.

[0024] The sampling tube is equipped with a shielding box, a fixing block, and a limiting threaded rod. The shielding box is symmetrically set on the front and back sides below the sampling tube. The fixing block is installed on the left and right sides of the outer side of the shielding box. The limiting threaded rod is inserted into the inside of the fixing block for threaded connection. That is, after the sampling tube has finished sampling, the shielding box can be installed on the front and back sides below the sampling tube to ensure that the soil sample will not slip.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 This utility model provides a technical solution: Example 1

[0034] To address the problems existing in the prior art, this embodiment provides the following technical solution: a concrete sampling mechanism, comprising a sampling cylinder 1; a disassembly mechanism located on the outside of the connecting ring 2, which allows the sampling cylinder 1 to be quickly removed from the mechanism for subsequent concrete testing; and a shielding mechanism located below the sampling cylinder 1, which allows the shielding box 18 to be installed below the sampling cylinder 1 after sampling is completed, ensuring that the sample soil inside the sampling cylinder 1 does not slip.The support mechanism, located below the support frame 8, provides firm support for the entire mechanism, ensuring stable sampling by the sampling cylinder 1. First, the worker can hold the handle 9 installed on the top of the support frame 8 to move the mechanism to the sampling location. Then, the bolts 13 fixing the support column 10 and the protective box 12 are loosened and pulled out, separating the support column 10 from the protective box 12. Next, the fixing cone 11 below the support column 10 is inserted into the ground. At this point, the support column 10 and the connecting rod 14 installed behind it will be firmly attached to the ground, and the entire mechanism is fixed in place. Then, the limiting threaded rod 20 is rotated to... The 20 and the fixing blocks 19 installed on the left and right sides of the shielding box 18 are separated. The shielding box 18 is removed from the front and rear sides below the sampling cylinder 1. Then, the sampling cylinder 1 is held by hand with the handle grooves 15 on the left and right sides above it. Since the connecting ring 2 is installed on the outside of the sampling cylinder 1, the mounting blocks 3 are installed on the left sides of the connecting ring 2. The mounting blocks 3 and the connecting blocks 6 inside the support frame 8 are tightly fitted. Then, the mounting blocks 3 and the connecting blocks 6 are fixed by the locking rod 4. The upper part of the locking rod 4 is also firmly locked to the locking groove 5 inside the upper part of the connecting block 6. The upper part of the connecting block 6 is connected to the spring 7. The upper part of the spring 7 is connected to the support frame 8. The upper part of the support frame 8 is fixedly connected, and the spring 7 has elasticity. Holding the handle 15 pushes the sampling cylinder 1 downwards. Since the sampling cylinder 1 is hollow, it contacts and compresses the concrete as it moves downwards, allowing concrete to enter the interior of the sampling cylinder 1 through its lower part. Because the sampling cylinder 1 is rotatably connected to the connecting ring 2, it can also be rotated appropriately to allow for faster sampling. After sampling, the handle 15 can be released. Due to the elasticity of the spring 7, the sampling cylinder 1 will rebound. Then, the shielding box 18 can be reinstalled below the sampling cylinder 1 to prevent the sample inside the sampling cylinder 1 from being contaminated. If soil slippage occurs, after sampling is completed in sampling cylinder 1, the locking rod 4 can be pulled out from inside the mounting block 3, connecting block 6, and locking groove 5. At this point, mounting block 3 will detach from connecting block 6, allowing sampling cylinder 1 to be removed from the mechanism, facilitating subsequent testing. Additionally, a push shaft 16 is installed in the middle of sampling cylinder 1, with a push plate 17 below it. To test concrete, the push shaft 16 and push plate 17 can be pushed downwards to push the concrete out of sampling cylinder 1. When the mechanism is not in use, the protective box 12 can be reinstalled on the outside of the fixing cone 11 to prevent workers from accidentally touching it and getting injured.

[0035] Existing sampling mechanisms cannot quickly detach the sampling cylinder 1 from the support, which affects subsequent concrete testing. Therefore, this embodiment adopts the following technical solution, such as... Figure 1 , Figure 4 and Figure 6As shown, the easy-to-disassemble mechanism includes a connecting ring 2 located on the outside of the sampling cylinder 1. Mounting blocks 3 are fixedly installed on the left and right sides of the outer side of the connecting ring 2. The inner side of the mounting block 3 is tightly fitted with the connecting block 6 located on the inner side of the support frame 8. At the same time, the mounting block 3 and the connecting block 6 are internally engaged with a locking rod 4. The upper inner side of the locking rod 4 is engaged with a locking groove 5 opened inside the upper part of the connecting block 6. That is, simply pulling the locking rod 4 forward will cause the mounting block 3 and the connecting block 6 to separate, and the sampling cylinder 1 can be removed from the mechanism. Example 2

[0036] In existing sampling devices, the sample may slip off the sampling head after concrete sampling is completed. Therefore, this embodiment addresses this issue by implementing the following technical solution: Figure 1 , Figure 3 and Figure 5 As shown, the shielding mechanism includes shielding boxes 18 set on the front and rear sides below the dry sampling tube 1. Since fixing blocks 19 are installed on the left and right sides of the outer side of the shielding box 18, and the fixing blocks 19 are threadedly connected with limiting threaded rods 20 inserted inside, the shielding box 18 can be installed on the front and rear sides below the sampling tube 1 after the sampling tube 1 has finished sampling, ensuring that the soil sample will not slip. Example 3

[0037] Existing sampling mechanisms generally require manual operation to sample concrete. However, during the sampling process, the mechanism may shift position, affecting sampling efficiency. Therefore, this embodiment addresses this issue through the following technical solution: Figure 3 and Figure 4 As shown, the support mechanism includes a support column 10 located below the support frame 8, and a fixed cone 11 located below the support column 10. When the equipment needs to be used, the protective box 12 on the outside of the fixed cone 11 can be removed first, and then the fixed cone 11 can be inserted into the ground. At this time, the lower part of the support column 10 and the connecting rod 14 installed on the rear side of the support column 10 will fit tightly with the ground, which can firmly fix and support the mechanism. When the worker pushes the sampling tube 1 downward, he can also step on the connecting rod 14 with his shoe, which can further improve the stability of the mechanism during sampling.
