Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery and equipment, in particular to a concrete sampler for concrete detection. Background Technique

[0002] Concrete, abbreviated as "砼", refers to a general term for engineering composite materials in which aggregate is cemented into a whole by cementitious materials. Generally, the term "concrete" refers to cement concrete made with cement as the cementitious material, sand and stone as aggregates; mixed with water (which may contain additives and admixtures) in a certain proportion and stirred. It is also called ordinary concrete and is widely used in civil engineering. In the production process of concrete, its proportion is very crucial. In the batching process of a small amount of concrete, small mechanical equipment is used for batching. After preliminary mixing and stirring, an appropriate amount of the stirred sample is generally taken for performance parameter detection such as slump.

[0003] A prior patent with the authorization announcement number CN 219870414 U and the patent name of "Concrete Detection Sampler" discloses a concrete detection sampler, which includes: a sampling cylinder, and a through hole is opened on the side wall of the sampling cylinder for the entry and exit of concrete; a sampling rod, the sampling rod is slidably arranged along the axis of the sampling cylinder, and a sampling plate is provided at the bottom of the sampling rod, and the periphery of the sampling plate is closely fitted with the inner wall of the sampling cylinder. When sampling, the bottom of the sampling cylinder is inserted into the concrete, and the concrete enters the inside of the sampling cylinder from the through hole and accumulates at the bottom end of the sampling cylinder. When different amounts of concrete sampling are required, only the height of the sampling rod needs to be adjusted up and down, and the positioning of the sampling plate is initially realized by using the friction between the sampling plate and the sampling cylinder, so that the distance between the sampling plate and the through hole can be changed. When pouring, the sampling rod is lifted upward, and the concrete can flow out naturally from the through hole.

[0004] During the use of the concrete sampler in the above patent, there will be concrete residues inside the sampling cylinder, which is not convenient for cleaning and affects the subsequent use of the concrete sampler. Content of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a concrete sampler for concrete detection, which is used to solve the technical problem that in the prior art, there will be concrete residues inside the sampling cylinder during the use of the existing concrete sampler, which is not convenient for cleaning for cleaning and affects the subsequent use of the concrete sampler.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a concrete sampler for concrete testing, comprising a sampling cylinder and a sampling tip, wherein the sampling cylinder and the sampling tip are fixedly connected, a first sampling port and a second sampling port are provided on the side of the sampling cylinder, the first sampling port and the second sampling port are used for sampling concrete, a water outlet pipe is provided inside the sampling cylinder, one end of the water outlet pipe extends out of the sampling cylinder and is connected to an external water tank, a booster water pump is provided on the water outlet pipe, and a plurality of water spray pipes are connected to one end of the water outlet pipe located inside the sampling cylinder, the water spray pipes respectively extend into the first sampling port and the second sampling port, a high-pressure nozzle is connected to the water spray pipe, and an isolation device for isolating the water spray pipe and the high-pressure nozzle is provided in the first sampling port and the second sampling port.

[0007] Working principle: When using this concrete sampler for concrete testing, technicians insert the sampling tube and sampling tip into the concrete, so that the sampler tip is in contact with the bottom of the container storing the concrete. The technician operates the sampling tube so that the first and second sampling ports sample the concrete in the container. After sampling, the sample is tested. During the sampling process, the isolation device remains closed. After sampling and testing, the technician opens the switch of the isolation device and the external water tank, so that the water in the external water tank flows into the spray pipe through the outlet pipe and the booster pump, and then sprays out a water jet through the high-pressure nozzle to rinse the concrete remaining in the first and second sampling ports.

[0008] Beneficial effects: Through the above technical solution, after the concrete sampler has finished sampling and testing, the inside of the first and second sampling ports can be cleaned through the water outlet pipe, water spray pipe and high-pressure nozzle, so as to avoid concrete residue on the inner walls of the first and second sampling ports during the sampling process, which would affect subsequent sampling after solidification; at the same time, a booster water pump is installed on the water outlet pipe, which can further increase the water pressure and increase the water pressure of the high-pressure nozzle, so that it can clean the inner walls of the first and second sampling ports more thoroughly.

[0009] The present invention is further configured such that: the isolation device includes a second hydraulic telescopic rod and a partition plate; the second hydraulic telescopic rod is fixedly mounted on the top wall of the sampling cylinder; the movable end of the second hydraulic telescopic rod is fixedly connected to the partition plate; the sampling cylinder has a channel for the second hydraulic telescopic rod and the partition plate to pass through; the channel forms passage openings on the side walls of the first sampling port and the second sampling port.

[0010] By adopting the above technical solution: when the technicians are taking samples for testing, they control the movable end of the second hydraulic telescopic rod to remain stationary, so that the baffle is able to block the high-pressure nozzle and the water spray pipe; after the sampling and testing is completed, the second hydraulic telescopic rod is activated, so that the movable end of the second hydraulic telescopic rod retracts, driving the baffle to move upward along the channel and the opening in the same direction inside the sampling tube, so that the baffle moves up to no longer block the high-pressure nozzle.

[0011] The present invention is further configured such that: sealing strips are provided at the passage openings on the side walls of the first sampling port and the second sampling port for the passage of the second hydraulic telescopic rod and the partition.

[0012] By adopting the above technical solution, when the partition moves, the sealing strip can increase the sealing between the passage opening and the partition, preventing concrete from leaking from the partition to the high-pressure nozzle during sampling and clogging the high-pressure nozzle.

[0013] The present invention is further configured such that: a sliding groove is provided on both sides of the first sampling port and the second sampling port, a slider is slidably connected in the sliding groove, a baffle is fixedly connected on the slider, a sampling hole of the same size as the first sampling port and the second sampling port is provided on the baffle, and an adjustment device is fixedly connected on the baffle.

[0014] By adopting the above technical solution: when the technician uses the concrete sampler to take samples, he activates the adjustment device, which causes the adjustment device to move the baffle. The slider connected to the baffle slides in the groove. When the baffle moves to the sampling hole without blocking the second sampling port, the technician moves the baffle to a suitable position according to the required amount of sample to take the sample. After the concrete enters the first and second sampling ports, the technician adjusts the baffle downwards to completely block the first and second sampling ports, leaving the concrete in the first and second sampling ports, thus completing the sampling.

[0015] The present invention is further configured such that: the adjusting device includes a first hydraulic telescopic rod and a connecting rod; a handle is provided on the top of the sampling cylinder; the first hydraulic telescopic rod is fixed on the handle on one side of the openings of the first and second sampling ports; the movable end of the first hydraulic telescopic rod passes through the handle and is fixedly connected to the connecting rod; and the end of the connecting rod away from the movable end of the first hydraulic telescopic rod is fixedly connected to the baffle.

[0016] By adopting the above technical solution: the technician holds the handle to take a sample. When taking a sample, the technician activates the first hydraulic telescopic rod, so that the movable end of the first hydraulic telescopic rod extends or retracts, which drives the connecting rod to move up and down, and then drives the baffle to move up and down to take a sample.

[0017] The present invention is further configured such that the grip has several rubber protrusions.

[0018] By adopting the above technical solution, the rubber protrusions can increase friction and prevent the gripper from slipping when gripping the handle.

[0019] The present invention is further configured such that: the connecting rod is provided with scale lines, and the sampling cylinder surface is provided with indicator lines.

[0020] By adopting the above technical solution: technicians determine the amount of concrete to be taken and adjust the position of the baffle moving up and down according to the scale lines.

[0021] The present invention is further configured such that the high-pressure nozzle faces the inner wall of the first sampling port and the second sampling port.

[0022] By adopting the above technical solution, the high-pressure nozzle can directly clean the inner walls of the first and second sampling ports, improving the cleaning effect. Attached Figure Description

[0028] Example:

[0029] like Figure 1 , Figure 2 and Figure 4As shown: A concrete sampler for concrete testing includes a sampling cylinder 1 and a sampling tip 2, which are welded together. A handle 3 is welded to the top of the sampling cylinder 1, and the handle 3 has several rubber protrusions 4. The concrete sampler is externally connected to a power source. A first sampling port 5 and a second sampling port 6 are opened on the side of the sampling cylinder 1. The first sampling port 5 and the second sampling port 6 are used to sample concrete. Sliding grooves 11 are opened on both sides of the first sampling port 5 and the second sampling port 6. A slider 22 is slidably connected in the sliding grooves 11. A baffle 7 is welded to the slider 22, and the baffle 7 has a... A sampling hole 20 of the same size as the first sampling port 5 and the second sampling port 6 is provided. An adjustment device is welded to the baffle 7. The adjustment device includes a first hydraulic telescopic rod 8 and a connecting rod 9. The first hydraulic telescopic rod 8 is installed on a handle 3 on one side of the openings of the first sampling port 5 and the second sampling port 6. The movable end of the first hydraulic telescopic rod 8 passes through the handle 3 and is welded to the connecting rod 9. The end of the connecting rod 9 away from the movable end of the first hydraulic telescopic rod 8 is welded to the baffle 7. The connecting rod 9 is provided with a scale line 10. The surface of the sampling cylinder 1 is provided with an indicator line 23, which is used to indicate the scale line 10.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown: The sampling cylinder 1 has an outlet pipe 17 inside, one end of which extends out of the sampling cylinder 1 and connects to an external water tank. A booster pump 13 is installed on the outlet pipe 17. Several spray pipes 15 are connected to the end of the outlet pipe 17 inside the sampling cylinder 1. The spray pipes 15 extend into the first sampling port 5 and the second sampling port 6, respectively. High-pressure nozzles 16 are connected to the spray pipes 15, facing the inner walls of the first sampling port 5 and the second sampling port 6. The first sampling port 5 and the second sampling port 6 are equipped with features for isolating the sprayed water. The isolation device for the pipe 15 and the high-pressure nozzle 16 includes a second hydraulic telescopic rod 12 and a partition 14. The second hydraulic telescopic rod 12 is installed on the top wall of the sampling cylinder 1. The movable end of the second hydraulic telescopic rod 12 is welded to the partition 14. The sampling cylinder 1 has a channel 21 inside for the second hydraulic telescopic rod 12 and the partition 14 to pass through. The side walls of the first sampling port 5 and the second sampling port 6 are provided with passage openings 18 for the second hydraulic telescopic rod 12 and the partition 14 to pass through. Each passage opening 18 is provided with a sealing strip 19.

[0031] Instructions for use: When using this concrete sampler for concrete testing, the technician inserts the sampling tube 1 and the sampling tip 2 into the concrete, so that the tip of the sampler is in contact with the bottom of the container storing the concrete. The technician then holds the handle 3 to take a sample.

[0032] In the initial state, the baffle 7 covers the first sampling port 5 and the second sampling port 6, and the sampling hole 20 on the baffle 7 is located between the first sampling port 5 and the second sampling port 6. The indicator line 23 is aligned with the zero mark of the scale line 10.

[0033] When sampling is required: First, the technician determines the amount of concrete to be sampled and adjusts the baffle 7 upward according to the scale line 10, thereby opening the lower parts of the first sampling port 5 and the second sampling port 6 and allowing adjustment of the opening size to ultimately determine the amount of concrete entering the first sampling port 5 and the second sampling port 6. The concrete at the first sampling port 5 flows in from below the baffle 7, and the concrete at the second sampling port 6 flows in through the sampling hole 20. Second, the sampler is vertically inserted into the concrete and left to stand for a period of time until the concrete has flowed into the first sampling port 5 and the second sampling port 6. Then, the baffle 7 is driven downward, at which point the baffle 7 covers the first sampling port 5 and the second sampling port 6 again, returning to its initial state. Third, the sampler is vertically pulled out of the concrete, thus completing the sampling work.

[0034] During sampling, the isolation device remains closed, and the movable end of the second hydraulic telescopic rod 12 remains stationary, ensuring that the partition 14 is positioned to block the high-pressure nozzle 16 and the water spray pipe 15. After sampling and testing, technicians connect the external water tank and the personnel outlet pipe 17, activate the movable end of the second hydraulic telescopic rod 12 to raise the partition 14, eventually moving it to a position where it no longer blocks the high-pressure nozzle 16. Then, the external water tank is opened, allowing water from the tank to flow through the outlet pipe 17 and the booster pump 13 into the water spray pipe 15, where it is then sprayed out through the high-pressure nozzle 16 to flush away the residual concrete in the first sampling port 5 and the second sampling port 6. After flushing, the second hydraulic telescopic rod 12 is activated, causing its movable end to retract, which moves the partition 14 down along the channel 21 and the passage opening 18 inside the sampling cylinder 1, re-blocking the water spray pipe 15 and the high-pressure nozzle 16.

[0035] When the partition 14 moves, the sealing strip 19 increases the sealing between the passage opening 18 and the partition 14, preventing concrete from leaking from the partition 14 to the high-pressure nozzle 16 during sampling and clogging the high-pressure nozzle 16. The high-pressure nozzle 16 can directly clean the inner walls of the first sampling port 5 and the second sampling port 6, improving the cleaning effect.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
