Description

Technical Field

[0001] This utility model relates to the field of road surface quality testing technology, specifically a road construction quality testing sampling device. Background Technology

[0002] Road construction quality testing sampling equipment is mainly used to drill or cut representative samples from the road structure to test its physical and mechanical properties. By analyzing the sample data, the bearing capacity, skid resistance and structural integrity of the road can be evaluated, construction defects or potential problems can be detected in a timely manner, and a scientific basis can be provided for project quality acceptance and maintenance decisions.

[0003] For example, Chinese Patent (Announcement No.: CN218546184U) discloses a drilling and coring device for municipal roads, including a device body. The device body includes a movable frame, with a bracket fixedly connected to the upper end of the movable frame. A housing is vertically and slidably connected to the bracket, and a core cylinder is rotatably connected to the lower end of the housing. A scraper ring is detachably installed on the bracket, and a material drop groove is provided inside the scraper ring. The outer wall of the core cylinder is inserted into the scraper ring. In this invention, the core cylinder moves downward to drill and cor through the municipal ground. The concrete adhering to the outer wall can be scraped off by the scraper ring during the upward movement of the core cylinder, so that the scraped concrete falls into the material drop groove, which facilitates the rapid cleaning of the outer wall of the core cylinder and prevents concrete from hardening on the outer wall of the core cylinder, which would cause drilling difficulties. Moreover, the scraper ring is detachable, which makes it convenient to replace the scraper ring after long-term friction damage, and facilitates the cleaning of the outer wall of the core cylinder.

[0004] However, the device is not easy to move and needs to be placed on an auxiliary structure such as a trolley to move, which is not convenient for actual use. Therefore, a road construction quality testing and sampling device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a road construction quality testing and sampling device that combines the advantages of convenient mobility and stable sampling, thus solving the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a road construction quality testing and sampling device, comprising a stabilizing component, four connecting rods fixed to the top of the stabilizing component, a top plate fixed to the top of the four connecting rods, a rotating mechanism penetrating the top plate and providing stable rotational force for sampling, a lifting component located to the right of the rotating mechanism and providing power for the lifting and lowering of the rotating mechanism, the lifting component penetrating the top plate, a water supply component providing stable water supply to the top of the top plate, a mudguard fixed to the top of the stabilizing component, and a handrail fixed between the stabilizing component and the top plate;

[0022] 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.

[0023] Please see Figures 1 to 2This embodiment of a road construction quality testing sampling device includes a stabilizing component 1. Four connecting rods 2 are fixed to the top of the stabilizing component 1, providing stable and reliable support for the top plate 3 and providing necessary space for the rotating mechanism 4 and the lifting component 6. The top of the four connecting rods 2 is fixed to the top plate 3. A rotating mechanism 4 penetrates the top plate 3 and provides stable rotational force for sampling. A lifting component 6, located to the right of the rotating mechanism 4 and providing power for its lifting and lowering, is located on the top of the top plate 3. The lifting component 6 penetrates the top plate 3. A water supply component 5 provides stable water supply to the top of the top plate 3. A mudguard 7 is fixed to the top of the stabilizing component 1, used to block mud generated during drilling and sampling, reducing the possibility of mud splashing onto workers. A handrail 8 is fixed between the stabilizing component 1 and the top plate 3.

[0024] Additionally, the stabilizing component 1 includes a base 101, with support heads 103 fixed on both the left and right sides of the base 101. The support heads 103 serve as an auxiliary tool, helping the user to more easily lift the device. The base 101 has two moving parts 102, and the bottom of the base 101 has two clearance grooves and two stabilizing grooves. The depth of the clearance grooves is greater than that of the stabilizing grooves. When the horizontal axis 1023 is located in the clearance groove, the two tires 1024 are only in contact with the ground. The base 101 also has two hinge holes, which provide reliable stability for the hinge rod 1021. Each movable part 102 provides a certain support function. Each movable part 102 includes a hinge rod 1021 fixed to the inner side of the hinge hole. Two hinge plates 1022 are rotatably connected to the outer surface of each hinge rod 1021. The two hinge plates 1022 are located on the front and rear sides of the base 101, respectively. A horizontal shaft 1023 is rotatably connected between each pair of hinge rods 1021. Two tires 1024 are rotatably connected to the outer surface of each horizontal shaft 1023. Each pair of tires 1024 is located on the opposite side of the two hinge plates 1022, and the two hinge plates 1022 serve as a connection.

[0025] It is known that a sampling hole is provided at the top of the base 101, and the top of the base 101 is fixed to the mudguard 7. Mud generally flies out from the sampling hole. At this time, the mudguard 7 can effectively block the mud. Since the mudguard 7 is circular in shape, it can block the mud more comprehensively. The mudguard 7 is circular in shape and is coaxial with the sampling hole.

[0026] In this embodiment, the support head 103 and the handrail 8 work together to make it easy for the user to lift the device. At the same time, by moving the two moving parts 102 in conjunction with the clearance groove and the stabilizing groove, the ease of moving the device can be improved, and the stability during sampling can be guaranteed.

[0027] Please refer to it again. Figure 1 and Figure 3 To improve the sampling quality, the rotating mechanism 4 in this embodiment includes a reducer 402 fixed to the top of the top plate 3. The main function of the reducer 402 is to increase the torque by reducing the rotation speed, thereby increasing the force of the drill bit 405. A drive motor 401 is fixed to the top of the reducer 402. The output shaft of the drive motor 401 is fixed to the input end of the reducer 402. The output end of the reducer 402 passes through the top plate 3. An active gear 403 is fixed to the outer surface of the output end of the reducer 402 and located below the top plate 3. The rotating mechanism 4 also includes a driven rod 404 that passes through the top plate 3. The bottom of the driven rod 404 is fixedly connected to the drill bit 405. When the driven rod 404 rotates, it can smoothly drive the drill bit 405 to rotate.

[0028] It should be further explained that the bottom of the top plate 3 is rotatably connected to the driven gear through a bearing. The driven gear meshes with the driving gear 403. The pitch circle diameter of the driven gear is larger than that of the driving gear 403. This can further reduce the output speed to increase the torque, thereby effectively improving the power of the driven rod 404 and the drill bit 405 below it when rotating. Multiple transmission keys are fixed on the outer side of the driven rod 404. Multiple keyways are opened on the inner side of the driven gear, which are adapted to the multiple transmission keys respectively. Through the cooperation of the transmission keys and keyways, it can be ensured that the rotational power can still be continuously transmitted during the downward movement of the driven rod 404.

[0029] In addition, the water supply assembly 5 includes a water pump 501 fixed to the top of the top plate 3. A water inlet pipe 502 is fixedly connected to the right side of the water pump 501. A water tank is fixedly connected to the side of the water inlet pipe 502 away from the water pump 501. An outlet pipe 503 is fixedly connected to the top of the water pump 501. A connecting pipe 504 is fixedly connected to the side of the outlet pipe 503 away from the water pump 501. The inner side of the connecting pipe 504 is rotatably connected to the driven rod 404 through a bearing. The connecting pipe 504 is connected to the driven rod 404. The center of the driven rod 404 is hollow. Since the driven rod 404 will rotate continuously, a bearing is needed to isolate the rotation of the driven rod 404 in order to ensure that water can be stably transmitted to the driven rod 404.

[0030] In addition, the lifting assembly 6 includes an electric push rod 601 that is fixed to and passes through the top plate 3. A connecting frame 602 is fixed to the bottom of the electric push rod 601. Two recessed seats 603 are fixed to the outer surface of the drill bit 405. Both recessed seats 603 are rotatably connected to the connecting frame 602. A bearing is fixed to the outer side of the recessed seat 603. The recessed seat 603 is rotatably connected to the connecting frame 602 through the bearing.

[0031] In this embodiment, the rotating mechanism 4 and the lifting component 6 work together to ensure that the drill bit 405 rotates and descends smoothly, thereby successfully sampling the road surface. Furthermore, the lifting component 6 can independently control the descent speed of the drill bit 405, improving the sampling quality.

[0032] It is understandable that by cooperating with the moving part 102 and the support head 103, portability is improved while ensuring good stability of the device during sampling. At the same time, by cooperating with the rotating mechanism 4, the water supply component 5 and the lifting component 6, the sampling quality is further improved.

[0033] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0034] The working principle of the above embodiments is as follows:

[0035] When in use, the user first holds the handle 8 and uses the support head 103 as a fulcrum to lift the device, then moves the two horizontal shafts 1023 into the clearance slots. Next, the device is lowered, ensuring the base 101 is fully in contact with the ground. The drive motor 401 is then started, and simultaneously the electric actuator 601 and water pump 501 are slowly activated. The power of the drive motor 401 is reduced by the reducer 402, amplifying the torque and further driving the drive gear 403 to rotate. The power is transmitted to the driven rod 404 and drill bit 405 through the driven gear, achieving stable rotation. The electric actuator 601 drives the connecting frame 602 to move, causing the drill bit 405 to slowly descend and sample the road surface. During sampling, the water pump 501 continuously supplies water to the drill bit 405 to ensure it does not overheat and improves construction safety.
