Description

Technical Field

[0001] This utility model relates to the technical field of roadbed compaction testing equipment, specifically to a hole-drilling machine for testing the compaction of filled roadbeds. Background Technology

[0002] After compaction, the compaction degree of a fill-filled roadbed needs to be tested, and the sand cone method is commonly used in current technology. When using the sand cone method to test the compaction degree of the roadbed, a circular sand-filling hole needs to be drilled along the path. After all the fill material in the hole is excavated, sand is filled in. The mass of the standard sand in the hole is calculated using a weighing device, and then divided by the density of the standard sand to obtain the volume of the hole. The weight of the soil removed from the hole is then divided by this volume to obtain the wet density of the soil sample, thus determining the compaction degree of the roadbed. Therefore, drilling is required in the fill-filled roadbed. However, because the hole is circular, existing roadbed drilling tools cannot quickly remove the material from the sand-filling hole, resulting in low testing efficiency. Utility Model Content

[0003] To address the technical problem that existing roadbed hole openers cannot directly remove the material from the sand-filled holes, this utility model provides a hole opener for testing the compaction degree of filled roadbeds. It can quickly remove the filler from the sand-filled holes along with the hole opener cylinder, thereby improving the testing efficiency of the compaction degree of filled roadbeds.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model provides a hole-drilling machine for detecting the compaction degree of fill roadbed, comprising: a hole-drilling frame; a hole-drilling cylinder, the lower end of which is blade-shaped; a linear actuator mounted on the hole-drilling frame for driving the hole-drilling cylinder to move up and down relative to the hole-drilling frame; and a material-supporting linkage mechanism installed inside the hole-drilling cylinder, which, when open, can compress the filler material inside the hole-drilling cylinder.

[0006] The hole-opening machine provided by this utility model includes a hole-opening frame, a hole-opening cylinder, a linear drive, and a material-supporting linkage mechanism. The lower end of the hole-opening cylinder is blade-shaped. The linear drive is installed on the hole-opening frame, and the material-supporting linkage mechanism is installed inside the hole-opening cylinder. In use, the hole-opening frame is moved to the desired hole-opening point, and then the linear drive drives the hole-opening cylinder to move up and down relative to the hole-opening frame. Since the lower end of the hole-opening cylinder is blade-shaped, it can be pressed into the filler subgrade. After the hole-opening cylinder is pressed into the set depth, the material-supporting linkage mechanism is driven to open to compact the filler inside the hole-opening cylinder. This allows the filler inside the hole-opening cylinder to move upward with the hole-opening cylinder when the linear drive drives it upward, eliminating the need to dig out the filler in the sand-filling hole. This improves the efficiency of detecting the compaction degree of the filler subgrade.

[0007] In an optional embodiment of this application, a mounting slide is further included. The mounting slide is slidably connected to the perforation frame. The perforation cylinder is mounted on the mounting slide, and the mounting slide is fixedly connected to the output end of the linear actuator. Compared with directly connecting the perforation cylinder to the linear actuator, this method facilitates the installation of the support rod mechanism and the opening of the drive support rod mechanism.

[0008] In an optional embodiment of this application, the linear actuator is a pneumatic cylinder, and the mounting slide is fixedly connected to the end of the piston rod of the linear actuator, so as to drive the pneumatic cylinder with compressed air to provide sufficient downward pressure to the perforated cylinder.

[0009] In an optional embodiment of this application, a pushing mechanism is further included. The pushing mechanism is installed on the perforated cylinder and is used to push out the packing material inside the perforated cylinder so as to quickly remove the packing material from the perforated cylinder.

[0010] In an optional embodiment of this application, the pushing mechanism includes: a pushing ring located inside the perforated cylinder and sleeved outside the supporting rod mechanism; and a pushing rod, one end of which is fixedly connected to the pushing ring and the other end of which is slidably inserted into the perforated cylinder.

[0011] Therefore, during the process of pressing down the perforated cylinder, the push rod and push ring move upward relative to the perforated cylinder under the push of the packing. After the perforated cylinder moves out of the sand filling hole, the push rod pushes the push ring to push the packing out of the perforated cylinder.

[0012] In an optional embodiment of this application, the mounting slide is provided with a first through hole, through which the upper end of the push rod can pass to ensure that the push rod can move upward relative to the perforated cylinder during the pressing down of the perforated cylinder.

[0013] In an optional embodiment of this application, both the push rod and the push ring are made of polytetrafluoroethylene (PTFE) to reduce the moving resistance of the push rod and the push ring by utilizing the self-lubricating properties of PTFE.

[0014] In an optional embodiment of this application, the support connection mechanism includes: a support rod, the upper end of which is screwed to the upper end of the perforated cylinder; a rotating ring, which is sleeved on the lower end of the support rod and is rotatable relative to the support rod; a first connecting rod, the upper end of which is hinged to the upper end of the perforated cylinder; a second connecting rod, which is disposed on the same side as the first connecting rod, with its upper end hinged to the lower end of the first connecting rod and its lower end hinged to the rotating ring; a third connecting rod, the upper end of which is hinged to the upper end of the perforated cylinder and is disposed on opposite sides of the support rod; and a fourth connecting rod, which is disposed on the same side as the third connecting rod, with its upper end hinged to the lower end of the third connecting rod and its lower end hinged to the rotating ring.

[0015] Therefore, by rotating the support rod, the rotating ring can be moved towards the upper end of the perforated cylinder, while simultaneously driving the first, second, third, and fourth connecting rods to move towards the corresponding side wall of the perforated cylinder. This causes the material support linkage mechanism to open, so that the first, second, third, and fourth connecting rods can squeeze the packing material inside the perforated cylinder, pressing it tightly inside the perforated cylinder, ensuring that the packing material inside can move synchronously when the perforated cylinder moves upward.

[0016] In an optional embodiment of this application, a second through hole is provided in the middle of the mounting slide, which allows the upper end of the support rod to pass through, so as to ensure that the support rod can move upward relative to the perforated cylinder.

[0017] In an optional embodiment of this application, the lower end of the support rod is conical, and the rotating ring is installed above the conical head of the support rod to reduce the resistance during the process of the linear actuator driving the perforated cylinder to move downward.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] This utility model provides a hole-drilling machine for testing the compaction degree of filled roadbeds. It includes a hole-drilling frame, a hole-drilling cylinder, a linear actuator, and a material-supporting linkage mechanism. The lower end of the hole-drilling cylinder is blade-shaped. The linear actuator is mounted on the hole-drilling frame, and the material-supporting linkage mechanism is installed inside the hole-drilling cylinder. In use, the hole-drilling frame is moved to the desired hole-drilling point. Then, the linear actuator drives the hole-drilling cylinder to move up and down relative to the hole-drilling frame. Because the lower end of the hole-drilling cylinder is blade-shaped, it can be pressed into the filled roadbed. After the hole-drilling cylinder is pressed into the set depth, the material-supporting linkage mechanism is driven to open, thus compacting the fill material inside the hole-drilling cylinder. This allows the fill material inside the hole-drilling cylinder to move upwards along with the hole-drilling cylinder when the linear actuator drives it upwards, eliminating the need to excavate the fill material in the sand-filling holes. Therefore, the efficiency of testing the compaction degree of filled roadbeds can be improved. Attached Figure Description

[0032] Example

[0033] Combination Figure 1 This utility model provides a hole-drilling machine for detecting the compaction degree of fill-filled roadbeds, comprising: a hole-drilling frame 10; a hole-drilling cylinder 20, the lower end of which is blade-shaped; a linear actuator 30, which is mounted on the hole-drilling frame 10 and is used to drive the hole-drilling cylinder 20 to move up and down relative to the hole-drilling frame 10; and a material-supporting linkage mechanism 40, which is installed inside the hole-drilling cylinder 20 and can compress the fill material inside the hole-drilling cylinder 20 when the material-supporting linkage mechanism 40 is open.

[0034] Combination Figure 2 This embodiment also includes a mounting slide 50, which is slidably connected to the opening frame 10. The opening cylinder 20 is mounted on the mounting slide 50, and the mounting slide 50 is fixedly connected to the output end of the linear driver 30. Compared with directly connecting the opening cylinder 20 to the linear driver 30, this method facilitates the installation of the material support linkage mechanism 40 and the opening of the material support linkage mechanism 40.

[0035] Specifically, the linear actuator 30 is a pneumatic cylinder, and the mounting slide 50 is fixedly connected to the end of the piston rod of the linear actuator 30, so as to provide sufficient downward pressure to the perforated cylinder 20 by driving the pneumatic cylinder with compressed air. Of course, a screw-slider mechanism driven by an electric motor or manually can also be used as the linear actuator 30.

[0036] Based on this, this embodiment also includes a pushing mechanism 60, which is installed on the perforated cylinder 20 and is used to push out the packing material inside the perforated cylinder 20 so as to quickly remove the packing material from the perforated cylinder 20.

[0037] Specifically, the pushing mechanism 60 includes: a pushing ring 61, which is located inside the perforated cylinder 20 and is sleeved outside the supporting rod mechanism 40; and a pushing rod 62, one end of which is fixedly connected to the pushing ring 61 and the other end is slidably inserted into the perforated cylinder 20.

[0038] Understandably, the inner diameter of the pusher ring 61 should be larger than the outer diameter of the upper end of the support linkage mechanism 40, while the outer diameter of the pusher ring 61 is smaller than the inner diameter of the perforated cylinder 20. Therefore, during the downward pressing of the perforated cylinder 20, the pusher rod 62 and the pusher ring 61 move upward relative to the perforated cylinder 20 under the push of the packing material. After the perforated cylinder 20 moves out of the sand filling hole, the pusher rod 62 pushes the pusher ring 61, thus pushing the packing material out of the perforated cylinder 20.

[0039] Correspondingly, the mounting slide 50 is provided with a first through hole 51, which allows the upper end of the push rod 62 to pass through, so as to ensure that the push rod 62 can move upward relative to the open cylinder 20 during the pressing down of the open cylinder 20.

[0040] The push rod 62 and the push ring 61 are both made of polytetrafluoroethylene (PTFE) to reduce the moving resistance of the push rod 62 and the push ring 61 by utilizing the self-lubricating properties of PTFE.

[0041] Combination Figure 2 and Figure 3The supporting connection mechanism includes: a support rod 45, the upper end of which is screwed to the upper end of the perforated cylinder 20; a rotating ring 46, which is sleeved on the lower end of the support rod 45 and is rotatable relative to the support rod 45; a first connecting rod 41, the upper end of which is hinged to the upper end of the perforated cylinder 20; and a second connecting rod 42, which is disposed on the same side as the first connecting rod 41, and the upper end of the second connecting rod 42 is connected to the upper end of the perforated cylinder 20. The lower end of the first connecting rod 41 is hinged to the rotating ring 46; the upper end of the third connecting rod 43 is hinged to the upper end of the perforated cylinder 20, and the third connecting rod 43 and the first connecting rod 41 are respectively located on opposite sides of the support rod 45; the fourth connecting rod 44 is located on the same side as the third connecting rod 43, the upper end of the fourth connecting rod 44 is hinged to the lower end of the third connecting rod 43, and the lower end is hinged to the rotating ring 46.

[0042] Therefore, by rotating the support rod 45, the rotating ring 46 can be driven to move towards the upper end of the perforated cylinder 20, and at the same time, the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 can be driven to move towards the corresponding side wall of the perforated cylinder 20, thereby causing the material support linkage mechanism 40 to open, so that the first connecting rod 41, the second connecting rod 42, the third connecting rod 43 and the fourth connecting rod 44 can squeeze the filling material inside the perforated cylinder 20 and press it tightly inside the perforated cylinder 20, ensuring that the filling material inside can move synchronously when the perforated cylinder 20 moves upward.

[0043] Optionally, a first pressure plate 47 and a second pressure plate 48 are fixed on the outer walls of the first connecting rod 41 and the third connecting rod 43 respectively. The lower ends of the first pressure plate 47 and the second pressure plate 48 extend to the lower end of the perforated cylinder 20, so that when the supporting connecting rod mechanism 40 is opened, the lower ends of the first pressure plate 47 and the second pressure plate 48 press the filler at the port of the perforated cylinder 20 to both sides, thereby ensuring that the filler at the port of the perforated cylinder 20 has sufficient compaction, ensuring that the filler inside the perforated cylinder 20 can be completely removed from the sand filling hole as the perforated cylinder 20 moves upward.

[0044] It is known that the mounting slide 50 is provided with a second through hole 52 in the middle. The second through hole 52 allows the upper end of the support rod 45 to pass through, so as to ensure that the support rod 45 can move upward relative to the perforated cylinder 20.

[0045] Preferably, the lower end of the support rod 45 is conical, and the rotating ring 46 is installed above the conical end of the support rod 45 to reduce the resistance during the process of the linear actuator 30 driving the perforated cylinder 20 to move downward.

[0046] In summary, the hole punching machine provided in this embodiment includes a hole punching machine frame 10, a hole punching cylinder 20, a linear actuator 30, and a material support linkage mechanism 40. The lower end of the hole punching cylinder 20 is blade-shaped. The linear actuator 30 is mounted on the hole punching machine frame 10, and the material support linkage mechanism 40 is installed inside the hole punching cylinder 20.

[0047] In use, the drilling frame 10 is moved to the desired drilling point. The operator stands on the base of the drilling frame 10 or adds a counterweight to the drilling frame 10 to prevent the drilling frame 10 from tilting upwards during the downward pressing of the drilling cylinder 20 by the linear actuator 30. Then, the drilling cylinder 20 is driven to move up and down relative to the drilling frame 10 by the linear actuator 30. Since the lower end of the drilling cylinder 20 is blade-shaped, it can be pressed into the filler roadbed. During the pressing of the drilling cylinder 20 into the roadbed, the material support connecting mechanism composed of the support rod 45 is simultaneously inserted into the filler. When the filler in the sand filling hole enters the drilling cylinder 20, it pushes the pusher ring 61 and the pusher rod 62 upwards.

[0048] After the perforated cylinder 20 is pressed into the set depth, the drive support linkage mechanism 40 opens to compress the filler inside the perforated cylinder 20. This allows the filler inside the perforated cylinder 20 to move upwards along with the perforated cylinder 20 when the linear actuator 30 drives it, eliminating the need to dig out the filler inside the sand filling hole. This improves the efficiency of detecting the compaction degree of the filler subgrade.

[0049] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
