Description
TECHNICAL FIELD
[0001] The present application relates to the field of highway construction quality detection equipment, in particular to a highway construction quality detection device. BACKGROUND
[0002] In the construction of highway traffic, the detection of the quality of the highway after construction is a key step to ensure the normal use of the highway. The detection of the quality of the highway construction generally uses a coring machine to drill a cylindrical core sample from the road surface, and analyzes the quality, thickness and material performance of the core sample to determine the construction quality of the highway.
[0003] However, after the coring machine drills the core column, the core column may fall into the core hole or be stuck in the drill cylinder. When it falls into the core hole, an additional clamping piece is usually used to clamp out the core sample, and since the gap between the core column and the core hole is small, the clamping piece increases the difficulty of taking the core. When the core column is stuck in the drill cylinder, the worker usually knocks the drill cylinder to move the core column out of the drill cylinder, but the knocking may cause the drill cylinder to deform and also reduces the work efficiency. SUMMARY

Meanwhile, the clamping assembly drives the first drill cylinder and the second drill cylinder to be close to each other, thereby clamping the push plate, and further improving the integrity of the cylindrical structure formed by the first drill cylinder, the second drill cylinder and the push plate.

[0014] Optionally, a shock-absorbing pad is installed in the mounting groove.
[0015] By adopting the technical scheme, the shock pad can reduce the impact force when the mounting block contacts with the inner wall of the mounting groove, thereby reducing the possibility of deformation of the mounting block.

[0019] By adopting the technical scheme, after the push plate continues to move to abut against the clearance block and the clearance surface, the first drill cylinder and the second drill cylinder are further away from each other, thereby facilitating the taking out of the core from between the first drill cylinder and the second drill cylinder.

[0027] 1. By coordinating the pushing and clamping components, the process of drilling, clamping, and removing the core column from the first and second drill barrels is realized, improving the efficiency of obtaining the core column during construction quality inspection. When sampling is required on the highway, the pushing drive drives the push plate to insert between the first and second drill barrels, forming an integral structure with the first and second drill barrels and the push plate, thus improving the deformation resistance of the first and second drill barrels. Simultaneously, the clamping component drives the first and second drill barrels closer together, clamping the push plate and further improving the overall integrity of the first and second drill barrels and the push plate. When the core column needs to be removed from the core hole, the push plate moves out from between the first and second drill barrels. At this time, the first and second drill barrels, driven by the clamping component, hold the core column tightly, facilitating its removal from the core hole. When the core column needs to be removed from between the first and second drill barrels, the push plate moves between them, further distancing the first and second drill barrels and releasing the core column for easy removal.

[0036] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.
[0037] This application discloses a highway construction quality testing device. For example... Figure 1 As shown, the testing device includes a base frame 1, a moving device 2, a core sampling device 3, and a support assembly 4.
[0038] Specifically, such as Figure 1 and Figure 2 As shown, casters 5 are installed on the base frame 1 to facilitate device movement. The support assembly 4 includes a support drive component 41 and a support plate 42. The body of the support drive component 41 is fixedly connected to the base frame 1, and the output end of the support drive component 41 is fixedly connected to the support plate 42. Preferably, the support drive component 41 is an electric push rod. In this embodiment, a support assembly 4 is installed at each of the four corners of the base frame 1. After the device moves to the designated position, the support drive component 41 drives the support plate 42 to move until it abuts the ground. The support plate 42 can support the detection device, reducing the possibility of the detection device moving during the acquisition of the core column.
[0039] like Figure 1 and Figure 2As shown, the moving device 2 includes a lifting mechanism 21 and a rotating mechanism 22. The lifting mechanism 21 includes a lifting support frame 211, a screw 212, a lifting seat 213, and a lifting drive component 214. Specifically, the lifting support frame 211 is fixedly connected to the base frame 1; both ends of the screw 212 are rotatably connected to the base frame 1 and the lifting support frame 211, respectively; the body of the lifting drive component 214 is fixedly connected to the lifting support frame 211, and the output end of the lifting drive component 214 is fixedly connected to the screw 212; the lifting seat 213 is slidably connected to the lifting support frame 211, and the lifting seat 213 is threadedly connected to the screw 212. The lifting drive component 214 drives the screw 212 to rotate, causing the lifting seat 213 to slide vertically on the lifting support frame 211. The rotating mechanism 22 includes a rotating drive component 221 and a rotating support frame 222. The body of the rotating drive component 221 is fixedly connected to the lifting seat 213, and the output end of the rotating drive component 221 is fixedly connected to the rotating support frame 222. Preferably, the rotating drive component 221 is a motor. Through the lifting mechanism 21 and the rotating drive component 221, the rotating support frame 222 can be raised, lowered, and rotated.
[0040] like Figure 1 and Figure 3 As shown, the core sampling device 3 includes a first drill barrel 31, a second drill barrel 32, a clamping assembly 33, and a pushing assembly 34. A diamond drill bit is fixedly connected to the bottom end of the first drill barrel 31, and the structure of the second drill barrel 32 is the same as that of the first drill barrel 31.
[0041] Furthermore, such as Figure 3 and Figure 4 As shown, the clamping assembly 33 includes a guide rod 331 and a first elastic element 332. The guide rod 331 passes between the first drill barrel 31 and the second drill barrel 32. In this embodiment, two guide rods 331 are installed. After passing through the first drill barrel 31 and the second drill barrel 32 respectively, the two ends of the guide rod 331 are fixedly connected to the rotating support frame 222, so that the first drill barrel 31 and the second drill barrel 32 can rotate together with the rotating support frame 222. The first elastic element 332 is sleeved on the guide rod 331. Preferably, the first elastic element 332 is a spring. One end of the first elastic element 332 is fixedly connected to the inner wall of the first drill barrel 31, and the other end is fixedly connected to the inner wall of the second drill barrel 32.
[0042] Furthermore, such as Figure 1 and Figure 3As shown, the pushing assembly 34 includes a pushing drive mechanism 341 and a pair of push plates 342. A connecting plate 343 is fixedly connected between the pair of push plates 342. The body of the pushing drive mechanism 341 is fixedly connected to the rotating support frame 222, and the output end of the pushing drive mechanism 341 is fixedly connected to the connecting plate 343. Preferably, the pushing drive component is a multi-stage electric push rod. By driving the connecting plate 343 to rise and fall through the pushing drive mechanism 341, the two push plates 342 can be simultaneously inserted between the sidewall edges of the first drill barrel 31 and the second drill barrel 32.
[0043] Among them, such as Figure 4 and Figure 5 As shown, a clearance surface 37, which is a slope, is provided at the upper end of the sidewall edge of both the first drill barrel 31 and the second drill barrel 32. An installation groove 35 is provided along the length of the sidewall edge of both the first drill barrel 31 and the second drill barrel 32. Installation blocks 36 are fixedly connected to both sides of the push plate 342. The shape of the installation groove 35 is adapted to the installation block 36, and the length of the push plate 342 is greater than the length of the installation block 36. When the push drive mechanism 341 drives the push plate 342 to insert between the first drill barrel 31 and the second drill barrel 32, the bottom of the push plate 342 first contacts the clearance surface 37, causing the first drill barrel 31 and the second drill barrel 32 to move away from each other, thus allowing the installation block 36 to be inserted into the installation groove 35.
[0044] In addition, a shock-absorbing pad is fixedly connected inside the mounting groove 35. The shock-absorbing pad can reduce the impact force when the mounting block 36 comes into contact with the inner wall of the mounting groove 35, thereby reducing the possibility of deformation of the mounting block 36.
[0045] It should be noted that when core drilling is required on the highway surface, the cylindrical structure formed after the pusher plate 342 is inserted between the first drill cylinder 31 and the second drill cylinder 32 contacts the ground and rotates at high speed to achieve core drilling. The design of the mounting block 36 and the mounting groove 35 improves the stability of the connection between the pusher plate 342 and the first drill cylinder 31 and the second drill cylinder 32.
[0046] Simultaneously, during the process of inserting the push plate 342 into the gap between the first drill barrel 31 and the second drill barrel 32, the first drill barrel 31 and the second drill barrel 32 move away from each other. After the push plate 342 is inserted, the first elastic element 332 is in a stretched state. At this time, under the action of the elastic force of the first elastic element 332, the first drill barrel 31 and the second drill barrel 32 clamp the push plate 342, further improving the stability of the connection between the first drill barrel 31, the second drill barrel 32 and the push plate 342.
[0047] After core drilling is completed in the cylindrical structure formed by the first drill barrel 31, the second drill barrel 32, and the pusher plate 342, the pusher drive mechanism 341 drives the pusher plate 342 to move upward. After the pusher plate 342 moves out from between the first drill barrel 31 and the second drill barrel 32, the first drill barrel 31 and the second drill barrel 32, under the elastic force of the first elastic member 332, clamp the core column, thereby removing the core column from the core hole when the lifting mechanism 21 moves the first drill barrel 31 and the second drill barrel 32 out of the core hole. Compared with the method of using additional clamping components to remove the core column from the core hole in related technologies, the work efficiency is improved.
[0048] In addition, such as Figure 5 As shown, a second elastic element 333 is also sleeved on the guide rod 331. Preferably, the second elastic element 333 is a spring. In this embodiment, a total of four second elastic elements 333 are installed. Two of the second elastic elements 333 are fixedly connected at one end to the first drill barrel 31 and at the other end to the rotating support frame 222. The other two second elastic elements 333 are fixedly connected at one end to the second drill barrel 32 and at the other end to the rotating support frame 222. The second elastic elements 333 can further improve the clamping force when the first drill barrel 31 and the second drill barrel 32 clamp the core column.
[0049] like Figure 3 As shown, a clearance block 38 is fixedly connected to the upper end of the push plate 342. After the first drill barrel 31 and the second drill barrel 32 remove the core column, the push plate 342 moves again between the sidewall edges of the first drill barrel 31 and the second drill barrel 32, and continues to move so that the clearance block 38 contacts the clearance surface 37. After the clearance block 38 contacts the clearance surface 37, the push plate 342 continues to move, causing the first drill barrel 31 and the second drill barrel 32 to move further away from each other, thereby releasing the core column and facilitating its removal. Compared with the method of removing the core column by striking the drill barrel in related technologies, this application reduces the possibility of drill barrel deformation and core column damage caused by striking, while also improving work efficiency.
[0050] The implementation principle of a highway construction quality testing device according to an embodiment of this application is as follows: The relative positions between the first drill barrel 31 and the second drill barrel 32 are divided into the initial position, the core drilling working position, and the core retrieval position during the core acquisition process. The distance between the sidewall edges of the first drill barrel 31 and the second drill barrel 32 increases sequentially in the initial position, the core drilling working position, and the core retrieval position.
[0051] Before core drilling begins, the detection device is moved to the target position and then supported on the ground using the support assembly 4 to ensure stability during core sample acquisition. At this time, the relative positions of the first drill barrel 31 and the second drill barrel 32 are in their initial positions. Then, the push drive mechanism 341 drives the push plate 342 to insert into the gap between the sidewall edges of the first drill barrel 31 and the second drill barrel 32. At this point, the relative position between the first drill barrel 31 and the second drill barrel 32 is in the core drilling working position.
[0052] When the first drill barrel 31 and the second drill barrel 32 are in the core drilling position, the rotating mechanism 22 drives the cylindrical structure formed by the first drill barrel 31, the second drill barrel 32 and the push plate 342 to rotate at high speed. At the same time, the lifting mechanism 21 drives the cylindrical structure to gradually move down until the core column is drilled out.
[0053] When it is necessary to remove the core column from the core hole, the push drive mechanism 341 drives the push plate 342 to move out of the space between the first drill barrel 31 and the second drill barrel 32. After the push plate 342 moves out, the first drill barrel 31 and the second drill barrel 32 hold the core column tightly under the elastic force of the first elastic element 332. At this time, the lifting mechanism 21 drives the first drill barrel 31 and the second drill barrel 32 to move out of the core hole and remove the core column.
[0054] When it is necessary to remove the core column from between the first drill barrel 31 and the second drill barrel 32, the push drive mechanism 341 drives the push plate 342 back between the first drill barrel 31 and the second drill barrel 32. After the push plate 342 moves until the clearance block 38 contacts the clearance surface 37, it continues to move, causing the first drill barrel 31 and the second drill barrel 32 to move further away from each other. At this time, the relative position between the first drill barrel 31 and the second drill barrel 32 is in the core-retrieving position. In the core-retrieving position, the inner walls of the first drill barrel 31 and the second drill barrel 32 cannot simultaneously contact the core column, thus facilitating core retrieval and completing the work of obtaining the core column in highway construction quality inspection.
[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
