Description

Technical Field

[0001] The present application relates to the technical field of asphalt sampling equipment, and in particular to a flexible asphalt sampling cylinder. Background Art

[0002] Asphalt sampling is performed to assess the quality and performance of asphalt. By testing and analyzing the sampled asphalt, we can determine whether it meets specific standards or specifications and is suitable for a specific project or application. This helps ensure the quality and safety of projects such as roads and buildings, while also helping to control costs and improve efficiency. Therefore, asphalt sampling is a crucial step in construction.

[0003] The prior art discloses an asphalt sampler, which includes a sampler body, a through hole is opened on the sampler body and along the length direction of the sampler body, a closing cover is provided at the upper end of the sampler body, a piston rod capable of moving up and down is installed in the through hole, the upper end of the piston rod extends out of the closing cover, and the lower end of the piston rod is connected to a sealing head adapted to the wall of the through hole. The shell of the sampler body is a hollow structure, a heat-conducting medium is installed in the shell, a heating resistor wire and a temperature sensor are provided in the shell, the temperature sensor is connected to a temperature controller, the heating resistor wire is connected to a power supply through an electric wire, a relay is connected to the electric wire, and the temperature controller is connected to the relay.

[0004] Regarding the above-mentioned related technologies, when sampling, the heating resistor wire is first powered by an external power supply. The heating resistor wire converts electrical energy into thermal energy to heat the shell, causing the shell temperature to rise. When sampling, the heated shell can increase the melting rate of the asphalt to speed up the sampling speed. However, when sampling the asphalt in the asphalt storage container, the through hole at the lower end of the shell is always open. In the process of sampling from the shell, the surface asphalt sample will also be included in the inner cavity of the shell. The surface asphalt sample is often prone to segregation and is not representative, thus affecting the accuracy of the detection after asphalt sampling. Utility Model Content

[0005] In order to improve the representativeness of asphalt sampling and ensure the accuracy after sampling and testing, the present application provides a flexible asphalt sampling cylinder.

[0006] The flexible asphalt sampling tube provided in this application adopts the following technical solution:

[0007] A flexible asphalt sampling cartridge comprising:

[0008] A sampling cylinder with an opening on the top wall;

[0009] a mounting rod connected to the sampling cylinder;

[0010] A cylinder cover, the cylinder cover is located on one side of the mounting rod, and the cylinder cover can cover the sampling cylinder and seal the top wall opening of the sampling cylinder;

[0011] A driving member is used to drive the cylinder cover to cover the top wall of the sampling cylinder. The driving member is installed on the installation rod and connected to the cylinder cover.

[0012] By adopting the above technical solution, force is first applied to the driving member, which drives the cylinder cover to move, so that the cylinder cover is pressed onto the top wall opening of the sampling cylinder and blocks the top wall opening of the sampling cylinder. Then, force is applied to the mounting rod, which drives the sampling cylinder to move toward the asphalt in the storage barrel until the sampling cylinder breaks through the surface asphalt and inserts to the target depth. Then, force is applied to the cylinder cover again by the driving member, so that the cylinder cover no longer blocks the top wall opening of the sampling cylinder, and the asphalt enters the sampling cylinder. Then, the driving member is used again to press the cylinder cover onto the top wall opening of the sampling cylinder. , and then apply tension to the mounting rod in the reverse direction. After taking out the sampling cylinder, the asphalt sample can be obtained for performance testing. The flexible asphalt sampling cylinder is designed to form a holding cavity for temporarily holding the asphalt sample through the sampling cylinder. The mounting rod can provide external support for the sampling cylinder to extend into the asphalt. The cylinder cover cooperates with the driving part to realize the opening and closing of the top wall of the sampling cylinder, and then the opening and closing of the sampling cylinder can be controlled during the asphalt sampling process to reduce the possibility of surface asphalt entering the holding cavity and finally affecting the accuracy of the test data after asphalt sampling and testing.

[0013] In a specific possible implementation scheme, the driving member includes a first pull rod, which is slidingly connected to the mounting rod, and the sliding direction of the first pull rod is consistent with the axial direction of the mounting rod. The first pull rod is connected to the barrel cover and is used to drive the barrel cover toward or away from the sampling barrel.

[0014] By adopting the above technical solution, the designed driving member can drive the cylinder cover to slide along the long side direction of the mounting rod through the first pull rod, thereby realizing the opening or closing of the top wall opening of the sampling cylinder.

[0015] In a specific embodiment, an oblique support rod is connected between the first pull rod and the cylinder cover.

[0016] By adopting the above technical solution, the designed diagonal support rod can increase the stability of the connection structure between the first pull rod and the cylinder cover, and reduce the possibility of the cylinder cover sinking into the asphalt.

[0017] In a specific possible implementation scheme, the driving member includes a second pull rod, the cylinder cover is rotatably connected to the mounting rod, two abutment blocks are connected to the second pull rod, and the cylinder cover extends between the two abutment blocks and can abut against the abutment blocks.

[0018] By adopting the above technical solution, the designed driving member can realize the rotation opening and closing action of the cylinder cover through the second pull rod and the abutment block cooperating with the mounting rod, thereby realizing the opening or closing of the top wall opening of the sampling cylinder.

[0019] In a specific possible implementation manner, the mounting rod is hollow, the driving member is slidably connected to the inner cavity of the mounting rod, and a strip-shaped clearance groove for the cylinder cover connecting section to pass through is formed on the mounting rod.

[0020] By adopting the above technical solution, the hollow installation rod and the strip-shaped clearance groove are designed to improve the position limitation and guidance of the installation rod movement.

[0021] In a specific possible implementation scheme, two sealing plugs are connected to the driving member, and the sealing plugs separate the inner cavity of the mounting rod into two chambers, and the strip-shaped clearance groove is connected to the cavity between the two sealing plugs.

[0022] By adopting the above technical solution, the sealing plug designed can confine the asphalt between the two sealing plugs, reducing the possibility of the asphalt flowing around after entering the inner cavity of the mounting rod through the strip-shaped give way groove during sampling.

[0023] In a specific embodiment, the mounting rod is covered with a rubber pad layer, and a plurality of friction protrusions are integrally formed on the rubber pad layer.

[0024] By adopting the above technical solution, the designed rubber pad layer can firstly play the role of isolating the heat of the installation rod, and secondly can facilitate the application of force to the installation rod.

[0025] In a specific embodiment, the lower end of the sampling cylinder is configured to be conical.

[0026] By adopting the above technical solution, the lower end of the design is set as a conical sampling cylinder, which makes it easier to break the asphalt surface and penetrate into the asphalt interior.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The flexible asphalt sampling cylinder is designed to form a holding cavity for temporarily accommodating asphalt samples through the sampling cylinder body. The mounting rod can provide external support for the sampling cylinder to extend into the asphalt. The cylinder cover cooperates with the driving member to realize the opening and closing of the top wall of the sampling cylinder body, thereby controlling the opening and closing of the sampling cylinder body during the asphalt sampling process to reduce the possibility of surface asphalt entering the holding cavity and ultimately affecting the accuracy of the test data after asphalt sampling and testing.

[0029] 2. The asphalt sampling cylinder is designed to be flexible. The cylinder cover can be opened and closed by rotating the second pull rod in conjunction with the mounting rod, thereby opening or closing the opening on the top wall of the sampling cylinder.

[0030] 3.
