Description

Technical Field

[0001] The utility model relates to the technical field of core sampling for road concrete detection, and particularly relates to a core sampling device for road concrete detection. Background Art

[0002] A road is an infrastructure for various trackless vehicles and pedestrians. According to its usage characteristics, it is divided into urban roads, highways, factory roads, forest roads, rural roads, etc. A road usually consists of a road surface, road shoulders, roadbeds, slopes, retaining walls, bridges and culverts, traffic engineering facilities, etc. In the construction and use process of a road, concrete is one of the key materials, and its quality and performance directly affect the safety, durability and service life of the road. Therefore, during the construction of a road, it is necessary to detect the concrete of the road, and during the detection process, a core sampling device is required to take samples of the detection samples. Currently, most core sampling devices are handheld sampling devices. When taking cores, in order to remove the dust generated during core sampling, water is splashed on the operation port during core sampling. As the device rotates and operates, the water used for dust removal will be splashed around, and thus the sewage will be splashed onto the bodies of the staff. Therefore, it is necessary to provide a core sampling device for road concrete detection to solve the above technical problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a core sampling device for road concrete detection to solve the problems raised in the above background art.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0005] A core sampling device for road concrete detection includes a vertical plate; one side of the bottom end of the vertical plate is fixedly installed with a horizontal plate, one side of the top end of the vertical plate is fixedly installed with a mounting plate, the upper surface of the mounting plate is fixedly installed with a mounting seat, a worm is rotatably connected inside the mounting seat, a worm gear is rotatably connected inside the mounting seat, and the worm and the worm gear are meshed and connected. One end of the worm passes through the side wall of the mounting seat and is fixedly installed with a handwheel. Two fixing seats are symmetrically and fixedly installed on one side of the vertical plate, a lead screw is rotatably connected between the two fixing seats, one end of the lead screw passes through the mounting plate and the side wall of the mounting seat and is fixedly connected with the worm gear, a sliding block is threadedly connected to the lead screw, and one end of the sliding block passes through the side wall of the vertical plate and is fixedly installed with a sampling assembly. The sampling assembly includes a rotating device, the rotating device is fixedly connected with one end of the sliding block, the input end of the rotating device is cooperatively connected with the input end of a motor, and the motor is fixedly installed at the top of the rotating device. The output end of the rotating device is fixedly connected with the top end of a sampling cylinder, and guiding grooves are symmetrically formed on both sides of the sampling cylinder.

[0006] The further improvement of the technical solution of the present utility model lies in that: currently, most core sampling devices are handheld sampling devices. When taking cores, in order to remove the dust generated during core sampling, water is splashed on the operation port during core sampling. As the device rotates, the water used for dust removal will be splashed around, which will splash the sewage onto the staff. In this solution, when the staff starts to use this device to take cores, the staff moves the device to the selected sampling point. At this time, the staff steps on the cross plate with their feet to limit the position of the device. Subsequently, the staff starts to rotate the handwheel. As the handwheel rotates, the worm will drive the worm gear to rotate, and the worm gear is fixedly connected to the lead screw. As the worm gear rotates, the lead screw will rotate synchronously, thereby causing the sliding block to descend along the vertical plate. As the sliding block descends, the sampling assembly fixedly connected to the sliding block will descend synchronously. The rotating device drives the sampling cylinder to rotate through a motor, and the sampling cylinder gradually contacts the concrete to carry out the sampling work. The water splashed during sampling will be blocked by the vertical plate, preventing it from splashing onto the staff.

[0007] Adopting the above technical solution, the symmetric fixed installation of the support frames at the connection between the vertical plate and the cross plate in this solution can increase the connection stability between the vertical plate and the cross plate, thereby increasing the overall connection stability of the device.

[0008] Adopting the above technical solution, a groove is provided on the upper surface of the cross plate in this solution.

[0009] The further improvement of the technical solution of the present utility model lies in that: the groove provided on the upper surface of the cross plate can be stepped on by the staff to limit the position of the device, thereby increasing the stability of the device during operation and making it more convenient for the staff to use.

[0010] Adopting the above technical solution, the sampling assembly in this solution further includes a sliding rod, the sliding rod is slidably connected in the guiding groove of the sampling cylinder, installation rib plates are fixedly installed at equal intervals on both sides of the sliding rod, the lower surface of the installation rib plate is fixedly connected to the upper surface of the pressing net, and the pressing net is slidably connected inside the sampling cylinder. Both ends of the sliding rod pass through the side wall of the sampling cylinder and are rotatably connected to a lower pressing block through a torsion spring. A sliding ring is slidably connected to the outside of the sampling cylinder, and the sliding ring is fixedly connected to the sliding rod.

[0011] A further improvement of the technical solution of the present utility model lies in that: as the sampling cylinder continues to move downward, the sampling cylinder begins to come into contact with the concrete and starts the sampling work. When the sampling cylinder finishes sampling, the staff resets the sampling cylinder. At this time, the staff flattens the pressing block, and then simultaneously applies a downward force to the pressing block with both hands. As the pressing block receives the downward force, the sliding rod, the mounting rib plate, and the pressing net connected and cooperated with the pressing block will move downward synchronously, realizing the downward pressing of the sample core in the sampling cylinder and taking out the sample core from the sampling cylinder. The setting of the sliding ring can increase the stability of the sliding rod during sliding, making the device operate more stably.

[0012] Adopting the above technical solution, through grooves are equidistantly arranged on the pressing block in the solution.

[0013] A further improvement of the technical solution of the present utility model lies in that: the arrangement of the through grooves on the pressing block forms several grooves on the surface of the pressing block, thereby increasing the friction between the pressing block and the staff's hand, making it more convenient for the staff to use the device.

[0014] Adopting the above technical solution, support seats are symmetrically and fixedly installed on the lower surface of the sliding ring in the solution.

[0015] A further improvement of the technical solution of the present utility model lies in that: the setting of the support seats can support the pressing block, so that when the pressing block is pressed downward, the support seats provide a certain supporting force, making the device operate more stably during operation.

[0016] Adopting the above technical solution, handles are symmetrically and fixedly installed on both sides of the vertical plate in the solution.

[0017] A further improvement of the technical solution of the present utility model lies in that: the setting of the handles makes it more convenient for the staff to carry the device.

[0018] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0019] 1. The present utility model provides a core sampling device for road concrete detection. Through the self-locking transmission mechanism formed by the worm and the worm wheel, the sampling cylinder can be stably lifted and lowered according to the working requirements, facilitating the staff to carry out the sampling work of the test samples. The setting of the vertical plate and the horizontal plate can separate the working area from the staff when the device is sampling, so that the water splashed during sampling will be blocked by the vertical plate, preventing it from splashing onto the staff.

[0020] 2. The utility model provides a core sampling device for road concrete inspection. The sliding rod, mounting rib plate and pressing net connected and matched with the lower pressing block will move downward synchronously to press the core sample in the sampling cylinder, so as to take out the core sample from the sampling cylinder, increasing the convenience of taking out the core sample and making it more convenient for the staff to use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following further elaborates on the present utility model in detail with reference to the embodiments:

[0031] Embodiment 1

[0032] As Figures 1-7As shown in the figure, the utility model provides a core sampling device for road concrete detection, which includes a vertical plate 1; one side of the bottom end of the vertical plate 1 is fixedly installed with a horizontal plate 2, one side of the top end of the vertical plate 1 is fixedly installed with a mounting plate 4, the upper surface of the mounting plate 4 is fixedly installed with a mounting seat 5, a worm 6 is rotatably connected inside the mounting seat 5, a worm gear 7 is rotatably connected inside the mounting seat 5, and the worm 6 and the worm gear 7 are meshed and connected. One end of the worm 6 passes through the side wall of the mounting seat 5 and is fixedly installed with a hand wheel 8. On one side of the vertical plate 1, fixing seats 9 are symmetrically and fixedly installed. A lead screw 10 is rotatably connected between the two fixing seats 9. One end of the lead screw 10 passes through the side walls of the mounting plate 4 and the mounting seat 5 and is fixedly connected with the worm gear 7. A sliding block 11 is threadedly connected to the lead screw 10, and one end of the sliding block 11 passes through the side wall of the vertical plate 1 and is fixedly installed with a sampling assembly. The sampling assembly includes a rotating device 12, the rotating device 12 is fixedly connected with one end of the sliding block 11, the input end of the rotating device 12 is cooperatively connected with the input end of a motor 13, and the motor 13 is fixedly installed at the top end of the rotating device 12. The output end of the rotating device 12 is fixedly connected with the top end of a sampling cylinder 14. Guide grooves 15 are symmetrically formed on both sides of the sampling cylinder 14.

[0033] In this embodiment, when the staff starts to use the device for core sampling, the staff moves the device to the selected sampling point. At this time, the staff steps on the horizontal plate 2 with their foot to limit the position of the device. Subsequently, the staff starts to rotate the hand wheel 8. As the hand wheel 8 rotates, the worm 6 will drive the worm gear 7 to rotate. Since the worm gear 7 is fixedly connected to the lead screw 10, as the worm gear 7 rotates, the lead screw 10 will rotate synchronously, thereby causing the sliding block 11 to descend along the vertical plate 1. As the sliding block 11 descends, the sampling assembly fixedly connected to the sliding block 11 descends synchronously. The rotating device 12 drives the sampling cylinder 14 to rotate through the motor 13, and the sampling cylinder 14 gradually contacts the concrete to perform the sampling work. The water splashed during sampling will be blocked by the vertical plate 1 to prevent it from splashing onto the staff.

[0034] As Figure 1 and Figure 2 shown, preferably, support frames 3 are symmetrically and fixedly installed at the connection between the vertical plate 1 and the horizontal plate 2.

[0035] In this embodiment, the setting of the support frames 3 can increase the connection stability between the vertical plate 1 and the horizontal plate 2, thereby increasing the overall connection stability of the device.

[0036] As Figure 2 shown, preferably, a groove is formed on the upper surface of the horizontal plate 2.

[0037] In this embodiment, the groove on the upper surface of the cross plate 2 is provided for the staff to step on, so as to limit the position of the device, thereby increasing the stability of the device during operation and making it more convenient for the staff to use.

[0038] Embodiment 2

[0039] As Figures 4-7 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the sampling assembly further includes a sliding rod 16, the sliding rod 16 is slidably connected in the guiding groove 15 of the sampling cylinder 14, and mounting rib plates 17 are fixedly installed at equal intervals on both sides of the sliding rod 16. The lower surface of the mounting rib plate 17 is fixedly connected to the upper surface of the pressing net 18, and the pressing net 18 is slidably connected inside the sampling cylinder 14. Both ends of the sliding rod 16 pass through the side wall of the sampling cylinder 14 and are rotatably connected with a pressing block 19 through a torsion spring. A sliding ring 20 is slidably connected to the outside of the sampling cylinder 14, and the sliding ring 20 is fixedly connected to the sliding rod 16.

[0040] In this embodiment, as the sampling cylinder 14 continues to move downward, the sampling cylinder 14 begins to contact the concrete and starts the sampling work. When the sampling cylinder 14 completes the sampling, the staff resets the sampling cylinder 14. At this time, the staff flattens the pressing block 19, and then, both hands apply a downward force to the pressing block 19 at the same time. As the pressing block 19 receives the downward force, the sliding rod 16, the mounting rib plate 17 and the pressing net 18 connected and cooperated with the pressing block 19 will move downward synchronously, so as to press the sample core in the sampling cylinder 14 and realize the extraction of the sample core from the sampling cylinder 14. The setting of the sliding ring 20 can increase the stability of the sliding rod 16 during sliding, making the device run more stably.

[0041] As Figures 4-7 shown, preferably, through grooves are equidistantly formed on the pressing block 19.

[0042] In this embodiment, the through grooves on the pressing block 19 make several grooves formed on the surface of the pressing block 19, thereby increasing the friction between the pressing block 19 and the staff's hand, making it more convenient for the staff to use the device.

[0043] Embodiment 3

[0044] As Figures 4-7 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, support seats 21 are symmetrically and fixedly installed on the lower surface of the sliding ring 20.

[0045] In this embodiment, the setting of the support seats 21 can support the pressing block 19, so that when the pressing block 19 is pressed downward, the support seats 21 provide a certain supporting force, making the device run more stably during operation.

[0046] Example 4

[0047] As Figure 1 and Figure 2 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, handles 22 are symmetrically and fixedly installed on both sides of the vertical plate 1.

[0048] In this embodiment, the provision of the handles 22 makes it more convenient for the staff to carry the device.

[0049] Next, the working principle of the core sampling device for road concrete detection will be specifically described.

[0050] As Figures 1-5 shown, when the staff starts to use the device for core sampling, the staff moves the device to the selected sampling point. At this time, the staff presses on the transverse plate 2 with their foot to limit the position of the device. Subsequently, the staff starts to rotate the handwheel 8. As the handwheel 8 rotates, the worm 6 drives the worm wheel 7 to rotate. Since the worm wheel 7 is fixedly connected to the lead screw 10, as the worm wheel 7 rotates, the lead screw 10 will rotate synchronously, causing the sliding block 11 to descend along the vertical plate 1. As the sliding block 11 descends, the sampling assembly fixedly connected to the sliding block 11 descends synchronously. The rotating device 12 drives the sampling cylinder 14 to rotate through the motor 13. As the sampling cylinder 14 continues to move downward, the sampling cylinder 14 starts to contact the concrete and begins the sampling work. When the sampling cylinder 14 completes the sampling, the staff resets the sampling cylinder 14. At this time, the staff flattens the pressing block 19, and then simultaneously applies a downward force to the pressing block 19 with both hands. As the pressing block 19 receives the downward force, the sliding rod 16, the mounting rib plate 17, and the pressing mesh 18 connected and cooperated with the pressing block 19 will move downward synchronously to press down the core sample in the sampling cylinder 14 and take out the core sample from the sampling cylinder 14.

[0051] Generally speaking, the present utility model has been described in detail above. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
