Description

Technical Field

[0001] The utility model relates to the technical field of concrete sampling, in particular to a concrete monitoring on-site sampler. Background Art

[0002] Concrete is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates mixed with water in a certain proportion, and the resulting cement concrete, also known as ordinary concrete, is widely used in civil engineering.

[0003] During the construction process, concrete needs to be sampled and tested before pouring in order to understand the mixing state of the concrete. Most existing concrete samplers are unable to sample concrete at different depths, and cannot detect the mixing state and humidity of concrete at different depths, and the detection range is limited. Utility Model Content

[0004] The purpose of the utility model is to provide a concrete monitoring on-site sampler to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete monitoring on-site sampler, comprising a supporting platform, the outer surface of the supporting platform is equidistantly provided with four brackets, one end of the four brackets is hingedly installed with a limit block, the bottom end of the limit block is provided with a telescopic support, a through column is inserted through the center position of the supporting platform, the bottom end of the through column is rotatably connected to a sampling barrel, the outer surface of the sampling barrel is equidistantly provided with four sampling ports, the same side of the four sampling ports is hingedly installed with a baffle, a low-speed motor is provided at the top end of the sampling barrel inside the through column, a reinforcement rod is provided at the output shaft position of the low-speed motor, four positioning columns are provided at the top of the supporting platform, the top ends of the four positioning columns are commonly connected to a top plate, the outer surfaces of the four positioning columns are commonly sleeved with a drive plate, and an electric push rod is provided at the middle position of the top plate.

[0006] Preferably, the output end of the electric push rod is fixedly connected to the top of the driving plate. When the electric push rod is in operation, it pushes or pulls the driving plate to make the through column move linearly upward or downward to adjust the height of the sampling tube.

[0007] Preferably, a positioning card is provided at one end of the bracket above the limit block to limit the rotation angle of the limit block. When the telescopic support is flipped outward to support the support platform, it will not flip excessively and cause unstable support.

[0008] Preferably, a protective cover is hingedly installed on the top of the sampling tube on one side of the through column. When sampling, the protective cover seals the top of the sampling tube to prevent concrete from different layers from entering the sampling tube. When sampling is completed, the protective cover is flipped open to facilitate the removal of concrete from the sampling tube.

[0009] Preferably, a telescopic sleeve is hingedly installed between one side of the baffle and the upper part of the inner wall of the sampling port, and a reset spring is provided inside the telescopic sleeve. The sampling tube is driven by a low-speed motor to rotate counterclockwise, and the concrete will squeeze the baffle to shrink the telescopic sleeve. The baffle is opened to allow the concrete to enter the sampling tube through the sampling port. When the sampling is completed, the reset spring pushes the telescopic sleeve to close the baffle to prevent concrete from different layers from entering the sampling tube.

[0010] Preferably, the bottom end of the driving plate is fixedly connected to the top end of the through column, so that the through column is limited by the positioning column, ensuring that the through column does not tilt when it is driven to perform linear motion.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The concrete monitoring on-site sampler is used in conjunction with a sampling tube through a through column. When sampling, the electric push rod pushes the drive plate to make the through column move linearly downward, so that the sampling tube is inserted into the concrete. The outer surface of the through column is provided with a scale. When sampling, the layer depth at the sampling position can be observed according to the scale on the top of the concrete. When the sampling tube is pushed to the layer depth required for sampling, the sampling tube is driven by a low-speed motor to rotate counterclockwise. The concrete will squeeze the baffle to shrink the telescopic sleeve, and the baffle is opened to allow the concrete to enter the sampling tube through the sampling port. When the sampling is completed, the reset spring pushes the telescopic sleeve to close the baffle to prevent concrete from different layers from entering the sampling tube. The concrete monitoring on-site sampler can sample concrete at different depths, which is convenient for comparing the mixing conditions and humidity of concrete at different positions.

[0020] like Figures 1 to 4As shown, the concrete monitoring site sampler of this embodiment includes a support platform 1. Four brackets 8 are equidistantly arranged on the outer surface of the support platform 1. One end of the four brackets 8 is hingedly installed with a limit block 9. The bottom end of the limit block 9 is provided with a telescopic support 7. The telescopic support 7 contains a spring button and an inner support rod for easy height adjustment, which supports the support platform 1 and ensures the stability of the concrete monitoring site sampler. A through column 6 is inserted through the center position of the support platform 1. The bottom end of the through column 6 is rotatably connected to a sampling barrel 12. Four sampling ports 13 are equidistantly arranged on the outer surface of the sampling barrel 12. A baffle 17 is hingedly installed on the same side of the four sampling ports 13. A low-speed motor 15 is provided at the top of the sampling barrel 12 inside the through column 6. The output shaft position of the low-speed motor 15 is set There is a reinforcing rod 14, which is fixedly connected to the sampling tube 12. When the low-speed motor 15 is running, it will drive the sampling tube 12 to rotate counterclockwise, and the concrete will squeeze the baffle 17 to open the baffle 17. The concrete enters the sampling tube 12 through the sampling port 13. Four positioning columns 2 are provided at the top of the supporting platform 1. The tops of the four positioning columns 2 are commonly connected to the top plate 3. The outer surfaces of the four positioning columns 2 are commonly sleeved with a driving plate 5. An electric push rod 4 is provided at the middle position of the top plate 3. When the electric push rod 4 is running, it will push or pull the driving plate 5 to make the through column 6 move linearly upward or downward to adjust the height of the sampling tube 12. The outer surface of the through column 6 is provided with a scale. When sampling, the layer depth at the sampling position can be observed according to the scale on the top of the concrete.

[0021] Specifically, the output end of the electric push rod 4 is fixedly connected to the top of the driving plate 5. When the electric push rod 4 is in operation, it pushes or pulls the driving plate 5 to make the through column 6 move linearly upward or downward to adjust the height of the sampling tube 12.

[0022] Furthermore, a positioning card plate 10 is provided at one end of the bracket 8 above the limit block 9, so that the rotation angle of the limit block 9 is limited. When the telescopic support 7 is flipped outward to support the support platform 1, it will not flip excessively and cause unstable support.

[0023] Furthermore, a protective cover 11 is hingedly installed on the top of the sampling tube 12 on one side of the through column 6. When sampling, the protective cover 11 seals the top of the sampling tube 12 to prevent concrete from different layers from entering the sampling tube 12. When sampling is completed, the protective cover 11 is flipped open to facilitate the removal of the concrete inside the sampling tube 12.

[0024] Furthermore, a telescopic sleeve 18 is hingedly installed between one side of the baffle 17 and the upper part of the inner wall of the sampling port 13. A reset spring 16 is provided inside the telescopic sleeve 18. The sampling tube 12 is driven by the low-speed motor 15 to rotate counterclockwise. The concrete will squeeze the baffle 17 to shrink the telescopic sleeve 18. The baffle 17 is opened to allow the concrete to enter the sampling tube 12 through the sampling port 13. When the sampling is completed, the reset spring 16 pushes the telescopic sleeve 18 to close the baffle 17 to prevent concrete from different layers from entering the sampling tube 12.

[0025] Furthermore, the bottom end of the driving plate 5 is fixedly connected to the top end of the through column 6, so that the through column 6 is limited by the positioning column 2, ensuring that the through column 6 does not tilt when being driven to perform linear motion.

[0026] The method of using this embodiment is as follows: when sampling concrete, first flip the four telescopic pillars 7 outward to support the support platform 1 steadily so that the sampling tube 12 is above the concrete to be sampled, and the driving plate 5 is pushed by the electric push rod 4 to make the through column 6 move linearly downward so that the sampling tube 12 is inserted into the concrete. The outer surface of the through column 6 is provided with a scale. When sampling, the layer depth at the sampling position can be observed according to the scale at the top of the concrete. When the sampling tube 12 is pushed to the layer depth required for sampling, the sampling tube 12 is driven by the low-speed motor 15 to rotate counterclockwise. The concrete will squeeze the baffle 17 to shrink the telescopic sleeve 18, and the baffle 17 is opened to allow the concrete to pass through the sampling port 13 into the sampling tube 12. When sampling is completed, the return spring 16 pushes the telescopic sleeve 18 to close the baffle 17 to prevent concrete from different layers from entering the sampling tube 12.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
