Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road engineering, in particular to a sample taker for road engineering detection. Background Art
[0002] Road engineering is an important branch of civil engineering, which involves the process of planning, designing, constructing and maintaining roads and related infrastructure. These infrastructures include but are not limited to highways, urban roads, bridges, tunnels, traffic management and control systems, etc. The goal of road engineering is to provide a safe, efficient and sustainable transportation network to support the movement of people and goods.
[0003] Sample samplers used in road engineering usually use coring machines to sample roads. However, existing coring machines for road coring sampling have some shortcomings. The height of the coring barrel is usually achieved by threaded rods and guide arm threaded feed movement. Since the guide arm is connected to support plates, drivers and other structures, the guide arm needs to bear the weight of various components, which will apply pressure to the threaded rod. The threaded rod is a frequently used component, and the threaded rod will be worn during the mutual movement of the guide arm and the threaded rod. Utility Model Content
[0004] The utility model provides a sampler for road engineering detection, which solves the problems mentioned in the above background technology.

[0021] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Reference Figure 1-2 A sample sampler for road engineering inspection includes a base 100, a guide mechanism 200 and a sampling mechanism 300; the guide mechanism 200 includes a guide column 210 symmetrically arranged on the base 100 and a guide arm 220 sleeved on the outside of the guide column 210 and guided to move along the guide column 210; the guide column 210 is a threaded column, and threaded barrels 221 are respectively arranged on both sides of the inside of the guide arm 220, and the inner side of the threaded barrel 221 is threadedly connected with the outer side of the threaded column.
[0023] The base 100 serves as the basic part of the sampler, supporting the entire structure and providing stability. The guide mechanism 200 includes a guide post 210 and a guide arm 220. The guide post 210 is symmetrically arranged on the base and plays a major guiding role. The guide arm 220 is sleeved on the outside of the guide post and performs guiding movement along the guide post. The sampling mechanism 300 is located at the bottom of the guide arm and is used for actual sampling operations. The key technical feature lies in the design of the guide post 210 and the guide arm 220. The guide post 210 is a threaded post, and threaded barrels 221 are respectively provided on both sides of the interior of the guide arm 220. The inner side of the threaded barrel 221 is connected to the external thread of the guide post 210 to form a mechanical matching relationship.
[0024] Through this design, the threaded connection between the guide post 210 and the guide arm 220 provides a stable guiding mechanism. This mechanism can ensure the accuracy and repeatability of the sampling mechanism 300 during the sampling operation. Since the guide arm 220 moves along the thread of the guide post 210, this design also helps to disperse the pressure generated during the sampling process, thereby reducing the wear on individual components and improving the durability and service life of the entire sampler.
[0025] In some embodiments, guide holes 222 are respectively provided on both sides of the inner part of the guide arm 220, and the guide holes 222 are adapted to the outer part of the threaded barrel 221. The existence of the guide holes 222 provides additional support and positioning for the threaded barrel 221, which helps to ensure the accuracy and stability of the guide arm 220 when it moves along the guide column 210. The design of the guide holes makes the guide arm more stable during movement, reducing sampling errors caused by vibration or offset.
[0026] In some embodiments, the inner diameter of the upper and lower openings of the guide hole 222 is smaller than the inner diameter of the middle portion. By making the inner diameter of the upper and lower openings of the guide hole 222 smaller than the inner diameter of the middle portion, this design enhances the limiting effect on the threaded barrel 221. The smaller inner diameter means that the threaded barrel 221 has a tighter fit at the upper and lower openings of the guide hole 222, which helps prevent the threaded barrel from being displaced or disengaged inside the guide hole. This design may also help optimize the mechanical properties of the sampler. The smaller inner diameter means that the pressure distribution of the threaded barrel 221 is more concentrated at the upper and lower openings of the guide hole 222, which helps to increase the friction between the guide arm and the threaded barrel, thereby providing better control during the sampling process.
[0027] In some embodiments, the guide arm 220 is symmetrically arranged by two plate-like members, and adjacent plate-like members are fixed by bolts. The guide arm 220 is symmetrically arranged by two plate-like members. This design simplifies the structure of the sampler and makes the guide arm easier to disassemble. When the threaded barrel 221 needs to be maintained or replaced, the plate-like members can be separated by loosening the bolts, so that the threaded barrel can be quickly accessed and processed, thereby improving maintenance efficiency. The design of the plate-like members and the bolt fixing method also help to enhance the durability of the guide arm. When subjected to repeated sampling operation forces, this structure can better disperse stress and reduce wear on a single connection point, thereby extending the service life of the guide arm.
[0028] In some embodiments, the guide mechanism 200 also includes a top plate 230 fixed on the top of the guide column 210, and the bottom of the top plate 230 is rotatably connected to a spiral rod 240 located between adjacent guide columns 210 and rotatably set at one end to the base 100, and the outer part of the spiral rod 240 is connected to the inner thread of the guide arm 220.
[0029] The addition of the top plate 230 provides additional support for the guide column 210, thereby enhancing the stability of the entire guide mechanism 200. This design helps to reduce the movement or deformation of the guide column caused by vibration or external force during the sampling process. The rotational connection between the bottom of the top plate 230 and the screw rod 240 provides an effective force transmission mechanism. The rotation of the screw rod 240 can be converted into a linear motion of the guide arm 220, and this conversion is achieved by the threaded connection between the outside of the screw rod and the inside of the guide arm. A rocking wheel is also provided on the top of the threaded rod 240. The rocking wheel design allows the operator to control the movement of the screw rod by turning the rocking wheel, thereby achieving precise control of the position of the guide arm 220. This design simplifies the operation process and makes the use of the sampler more convenient and intuitive. Through the coordinated use of the screw rod 240 and the rocking wheel, the position of the guide arm 220 can be finely adjusted. The proportional relationship between the rotation of the screw rod and the linear motion of the guide arm (i.e., the pitch) determines the accuracy of the control, making the adjustment of the sampling depth more precise.
[0030] The operator rotates the crank to drive the screw rod 240 to rotate. The rotation of the screw rod is transmitted to the guide arm 220 through the threaded connection. As the screw rod 240 rotates, the guide arm 220 performs linear motion along the external thread of the guide column 210 to adjust the vertical position of the sampler. When the guide arm 220 moves to the appropriate position, the sampling mechanism 300 can perform the sampling operation.
[0031] In some embodiments, the sampling mechanism 300 includes a support plate 310 that is bolted to the bottom of the guide arm 220. A driver 320 is provided on one side of the support plate 310, and a core barrel 330 is provided on the other side. The output shaft of the driver 320 is connected to the external transmission of the core barrel 330 through a belt.
[0032] The support plate 310, as a basic component, provides sufficient support force, making the sampling process more stable and accurate. A driver 320 is provided on one side of the support plate 310, which indicates that the sampling mechanism is equipped with a power source for driving the core barrel 330. The driver includes but is not limited to an electric motor, a diesel engine or other types of mechanical power devices, which provide the necessary power for the sampling mechanism. The output shaft of the driver 320 is connected to the external transmission of the core barrel 330 through a belt, and this transmission method is simple and efficient. Belt drive can provide smooth power transmission, reduce energy loss, and allow a certain degree of speed adjustment.
[0033] The driver 320 on the support plate 310 is started to generate rotational power. The output shaft of the driver 320 transmits power to the coring barrel 330 through a belt, causing the coring barrel to rotate. As the operator rotates the crank, the driving screw 240 drives the coring barrel 330 to descend, and the coring barrel 330 in the rotating process will penetrate the road surface and obtain samples.
[0034] In some embodiments, a steering wheel 110 and pulleys 120 are provided on one side of the base 100. A handrail 130 is also provided on the top of the base 100 away from the guide column 210.
[0035] The provision of the steering wheel 110 allows the base 100 to be easily moved on the ground. This design reduces the labor required to transfer the sampler between different sampling points, improves work efficiency, and enables the sampler to adapt to a variety of different working environments. The pulleys 120 are located on both sides of the other side of the base, and this design helps to provide additional stability when fixing the sampler. The armrest 130 is provided on the top of the base, providing the operator with a component to hold in order to maintain balance and stability during sampling operations.
[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
