Description

Technical Field

[0001] This utility model relates to the field of roadbed coring technology, specifically to a roadbed paving thickness detection device. Background Technology

[0002] Roadbed thickness measurement is a core part of road engineering quality control. Roadbed thickness measurement requires the use of a core drilling machine to drill holes in the road surface to obtain core samples. As the drill rod rotates at high speed and drills into the road surface, it will generate high temperatures due to strong friction. In order to extend the service life of the drill rod, it is necessary to spray water for cooling.

[0003] However, adding extra water will cause the water to carry the drilled dust across the paved road surface, and some of the polluted water will seep under the road surface, contaminating the already paved road.

[0004] This solution provides a roadbed paving thickness detection device, which adds a physical barrier mechanism to the existing core drilling rig to ensure that the cooling water is controllable. Utility Model Content

[0005] (a) Technical issues

[0006] The present invention aims to at least solve the problem in the prior art that the cooling water used during core drilling carries dust and overflows onto the road surface, causing pollution.

[0007] (II) Technical Content

[0008] This solution provides a roadbed paving thickness detection device, achieved through the following specific technical means, including:

[0009] A U-shaped base frame with its opening facing forward is provided, and a core drilling machine is installed in the middle and rear of the U-shaped base frame, with the core cylinder of the core drilling machine located in the middle and front of the U-shaped base frame.

[0010] The barrier tube is positioned directly opposite the core drill tube. The bottom end of the barrier tube is placed on the road surface and surrounds the location where the core sample is to be taken. When the core drill tube moves down, it will enter the barrier tube.

[0011] The pressure-applying mechanism is installed on a U-shaped base frame and connected to the barrier cylinder. It is used to transmit the force exerted by the worker stepping on the pressure-applying mechanism to the barrier cylinder.

[0012] Preferred technical solution 1: A discharge port is provided on the barrier cylinder wall near the bottom, and a plug or connecting hose is inserted into the discharge port.

[0013] Preferred technical solution 2: The pressing force application mechanism consists of two sets of pedal components. The two sets of pedal components are respectively movably installed on two opposite sides of the U-shaped base frame, and the close ends of the two components are movably connected to the outer walls of both sides of the barrier cylinder.

[0014] The pedal assembly includes a support fixed to the side wall of the U-shaped base and a pedal hinged to the support. A horizontal shaft is fixed at one end of the pedal near the barrier cylinder, and a horizontal frame is fixed on the side wall of the barrier cylinder. The horizontal shaft passes through a horizontal hole opened on the horizontal frame and can slide along the horizontal hole.

[0015] Preferred technical solution 3: An elastic gasket is wrapped around the bottom opening of the barrier cylinder to increase the sealing effect between the barrier cylinder and the road surface.

[0016] Preferred technical solution four: A spring is connected between the support and the pedal, and the spring provides elastic support for the pedal.

[0017] Preferred technical solution five: A crossbar is fixed on the outside of the support, and a baffle is fixed at the end of the crossbar. At the same time, a movable plate is slidably sleeved on the crossbar, and the two ends of the spring sleeved on the crossbar are connected to the baffle and the movable plate respectively.

[0020] (III) Technical Effects

[0021] The above structure gives this solution the following advantages:

[0022] 1. By adding a barrier cylinder, the cooling water surrounding the core sample can be physically blocked during core sampling, facilitating subsequent collection and processing.

[0023] 2. By using the stepping component connected to the barrier cylinder, the weight of the construction workers is applied to the barrier cylinder, which further improves the contact effect with the road surface and reduces the impact of equipment vibration on the barrier effect.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-3 The roadbed paving thickness detection device includes a U-shaped base frame 1, a barrier cylinder 3, and a compaction mechanism 4. The U-shaped base frame 1 has its opening facing forward. A core drilling rig 2 is installed at the rear of the U-shaped base frame 1. The core drilling cylinder 29 on the core drilling rig 2 is located at the front of the U-shaped base frame 1. The specific structure of the core drilling rig 2 is as follows:

[0032] The core drilling rig 2 includes a frame 21 fixed on a U-shaped base frame 1 and a mounting base 22 that slides and rises on the frame 21. The mounting base 22 is threadedly connected to a screw 23 rotatably mounted on the U-shaped base frame 1 through a threaded hole. A handwheel 24 is fixed to the top of the screw 23. Rotating the handwheel 24 controls the rotation of the screw 23, thereby adjusting the height of the mounting base 22. A motor 25 is fixed in the housing on the rear side of the mounting base 22. A rotating shaft 26 is rotatably mounted through the mounting cavity on the front side of the mounting base 22. The top of the core barrel 29 is fixed to the bottom of the rotating shaft 26. A transmission belt 28 is connected between the output shaft of the motor 25 and the pulley 27 fixed on the rotating shaft 26. The tensioned transmission belt 28 transmits the power of the output shaft of the motor 25 to the rotating shaft 26 to drive the core barrel 29 to rotate.

[0033] It is worth noting that the specific models of the motor 25 and screw 23 mentioned in this embodiment, as well as their matching power supply and control switch, can also be provided by the manufacturer. For example, the power supply can be provided by an external mobile power supply. The circuits, electronic components and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and there is no need to elaborate.

[0034] The mounting base 22 is also fixed with a water inlet pipe 210. The top of the water inlet pipe 210 is connected to a water supply device (such as a water pump), and the bottom end passes through the inner cavity of the rotating shaft 26 (the diameter of the water inlet pipe 210 is smaller than the inner cavity diameter of the rotating shaft 26) and enters the core barrel 29. Cooling water is added to the water inlet pipe 210 through the external water supply device and then sprayed into the core barrel 29 for cooling.

[0035] The barrier cylinder 3 is directly opposite the core cylinder 29, and its inner diameter is larger than that of the core cylinder 29. During core drilling, the bottom end face of the barrier cylinder 3 is placed on the road surface and surrounds the core sampling position (an elastic washer 32 is wrapped around the bottom opening of the barrier cylinder 3 to increase the sealing effect between the barrier cylinder 3 and the road surface). When the core cylinder 29 moves down, it will enter the barrier cylinder 3. At this time, the cooling water used in the core drilling process will accumulate in the barrier cylinder 3 to prevent the cooling water from flowing out randomly.

[0036] The pressing force application mechanism 4 is installed on the U-shaped base frame 1 and connected to the barrier cylinder 3. Before drilling, the worker needs to step on the pressing force application mechanism 4. The force transmission makes the barrier cylinder 3 pressed tightly on the ground. On the one hand, it can increase the contact force between the barrier cylinder 3 and the road surface and improve the sealing effect. On the other hand, the application of the stepping force can also reduce the impact of the vibration generated during the operation of the device on the barrier cylinder 3, and prevent the barrier cylinder 3 from reducing the sealing effect due to vibration. A discharge port 31 is opened on the wall of the barrier cylinder 3 near the bottom. A plug or connecting hose is inserted into the discharge port 31.

[0037] If a plug is used, the sewage can be retained in the barrier cylinder 3, which facilitates subsequent centralized treatment, such as using other suction tools or dipping tools to remove the sewage.

[0038] The flexible hose is laid and transferred to the dustproof cloth or plastic sheet laid on the ground or roadside, and then put into a sealed bag for disposal as construction waste.

[0039] Please see Figure 1 , Figure 4 The roadbed paving thickness detection device and the compaction force application mechanism 4 consist of two sets of compaction components 41. The two sets of compaction components 41 are respectively movably installed on two opposite sides of the U-shaped base frame 1, and their close-to-each ends are movably connected to the outer walls of both sides of the barrier cylinder 3. Specifically:

[0040] The pedal assembly 41 includes a support 411 fixed on the side wall of the U-shaped base frame 1 and a pedal 412 hinged to the support 411. The pedal 412 has an anti-slip structure. A horizontal shaft 413 is fixed at one end of the pedal 412 near the barrier cylinder 3. At the same time, a horizontal frame 33 is fixed on the side wall of the barrier cylinder 3 corresponding to the position of the pedal assembly 41. The horizontal shaft 413 passes through a horizontal hole 331 opened on the horizontal frame 33 and can slide along the horizontal hole 331. The two ends of the horizontal hole 331 face the support 411 and the barrier cylinder 3 respectively. The horizontal shafts 413 on the two sets of pedals 412 are slidably connected to the two sets of horizontal frames 33 on both sides of the barrier cylinder 3. When in use, the operator's two feet step on the two sets of pedals 412 respectively, and the weight of the human body provides downward pressure to the barrier cylinder 3.

[0041] The sliding fit between the horizontal hole 331 and the horizontal shaft 413 can adapt to the change in the distance between the blocking cylinder 3 and the support 411 when the pedal 412 is stepped on. When stepped on, the gravity is transmitted to the horizontal frame 33 through the pedal 412 and the horizontal shaft 413, providing the force to press down on the blocking cylinder 3.

[0042] Please see Figure 4 The roadbed paving thickness detection device has a crossbar 414 fixed on the outside of the support 411, and a baffle 415 fixed at the end of the crossbar 414. A movable plate 416 is slidably sleeved on the crossbar 414. A spring 418 slidably sleeved on the crossbar 414 is connected at both ends to the baffle 415 and the movable plate 416 respectively. The spring 418 is in a compressed state. A protruding handle 417 is fixed at the connection end between the pedal 412 and the support 411. The protruding handle 417 contacts the movable plate 416. When not stepped on, the spring 418 pushes the movable plate 416 closer to the support 411. The pushing force of the movable plate on the protruding handle 417 causes the pedal 412 to tilt upward and lift the barrier cylinder 3.

[0043] When the pedal 412 is stepped on, gravity causes the pedal 412 to be pressed down. At this time, the convex handle 417 swings outward, pushing the movable plate 416 to further compress the spring 418. At the same time, the horizontal shaft 413 slides along the horizontal hole 331 and approaches the barrier cylinder 3. It is worth noting that the barrier cylinder 3 can be a lightweight cylinder. At the same time, the rebound force of the spring 418 is much less than the weight of the construction worker. When the construction worker steps on the pedal 412 with his feet apart, he can use both hands to grasp the handwheel 24 to rotate it. When the construction worker steps on the pedal 412, it can not only provide enough force to compress the spring 418, but also apply enough force to the barrier cylinder 3.
