Description

Technical Field

[0001] This utility model relates to the field of core sample drilling support technology, specifically to a core sample drilling support for road engineering. Background Technology

[0002] In road engineering quality inspection, core sampling is a crucial step in assessing the structural strength of the pavement. Traditional drilling equipment often relies on a motor to drive the sampling cylinder to rotate. However, in field operations, the motor is prone to damage due to humid environments or overload, leading to sampling interruptions.

[0003] Furthermore, when encountering soft geological sections, the downward pressure from rotation alone is insufficient, causing the sampling cylinder to slip and affecting the integrity of the core sample. While existing supports can adjust the drilling depth, they lack emergency auxiliary power, making them unable to cope with sudden equipment failures or complex geological conditions, leading to reduced testing efficiency. Therefore, there is an urgent need for a drilling support that combines electric drilling and manual impact modes to improve equipment reliability and adaptability. This paper proposes a core sample drilling support for road engineering. Utility Model Content

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A core sample drilling support for road engineering includes a base frame, with support columns symmetrically and vertically fixedly installed on the upper side of the base frame. A fixing plate is fixedly sleeved on the upper side of the support column, and a movable frame is movably sleeved on the side of the support column. An adjusting rod is threaded through the side of the movable frame and is rotatably installed through the fixing plate and the base frame. An installation plate is provided on the side of the movable frame, and an auxiliary component for manual sampling is provided on the side of the movable frame.

[0007] Furthermore, the auxiliary component includes an active cavity formed on the side of the active frame, and a mounting plate is movably disposed inside the active cavity. A constraint rod is symmetrically fixedly installed inside the active cavity and passes through the mounting plate. A support spring is symmetrically fixedly connected between the lower side of the mounting plate and the bottom wall of the active cavity, and the support spring is movably sleeved on the side of the constraint rod.

[0008] Furthermore, an impact rod is provided on the upper side of the mounting plate, and a support cylinder is fixedly connected between the side of the impact rod and the top wall of the movable cavity. A counterweight is provided on the upper side of the impact rod, and a mating cavity is opened on the lower side of the counterweight.

[0009] Furthermore, the impact rod extends through the movable frame. The impact rod is a T-shaped round rod with threads on the side. The support cylinder is a corrugated cylinder made of elastic material. The mating cavity is threadedly fitted onto the side of the impact rod. The mating cavity is a convex cylindrical threaded groove.

[0010] Furthermore, the bottom side of the impact rod has an inner cavity that extends through it, and a trigger rod is movably installed inside the inner cavity. A connecting cylinder is fixedly connected between the side of the trigger rod and the upper side of the impact rod, and a nail gun cartridge is snapped into place inside the inner cavity.

[0011] Furthermore, the inner cavity is a T-shaped cylindrical groove, the trigger rod extends from the inner cavity to the mating cavity, the trigger rod is a T-shaped round rod, the connecting cylinder is movably sleeved on the side of the trigger rod, the connecting cylinder is a corrugated cylinder of elastic material, and the nail gun is attached to the upper side of the mounting plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1.

[0024] Example: Figures 1 to 2 As shown, a core sample drilling support for road engineering includes a base frame 1, which is an "H"-shaped frame. Support columns 11 are symmetrically and vertically fixed on the upper side of the base frame 1. The support columns 11 are cylindrical rods. A fixing plate 12 is fixedly sleeved on the upper side of the support columns 11. The fixing plate 12 is a rectangular plate with two sets of circular grooves on the side. A movable frame 13 is movably sleeved on the side of the support columns 11. The movable frame 13 is a convex-shaped plate with two sets of circular grooves on the side. An adjusting rod 14 is threaded through the side of the movable frame 13 and is rotatably installed through the fixing plate 12 and the base frame 1. The adjusting rod 14 is a "T"-shaped cylindrical threaded rod. An mounting plate 15 is provided on the side of the movable frame 13. The mounting plate 15 is a rectangular plate with circular grooves on the side. An auxiliary component 2 for manual sampling is provided on the side of the movable frame 13.

[0025] Specifically, the sampling cylinder can be placed on the lower side of the mounting plate 15, and a motor can be fixed on the upper side. The sampling cylinder is driven to rotate by the motor, and the adjusting rod 14 is driven to rotate manually or electrically. The adjusting rod 14 is threadedly engaged with the movable frame 13, and the fixed plate 12 is moved in a constrained position on the side of the support column 11. This allows for normal sampling. The auxiliary component 2 can be used in cases where the motor is damaged or the soil is soft.

[0026] As shown in Figure 2, auxiliary components to Figure 5 As shown, the auxiliary component 2 includes a movable cavity 21 formed on the side of the movable frame 13, and a mounting plate 15 movably disposed inside the movable cavity 21. The movable cavity 21 is a rectangular groove. A constraint rod 22 is symmetrically fixedly installed inside the movable cavity 21, and the constraint rod 22 passes through the mounting plate 15. The constraint rod 22 is a cylindrical rod. A support spring 23 is symmetrically fixedly connected between the lower side of the mounting plate 15 and the bottom wall of the movable cavity 21, and the support spring 23 is movably sleeved on the side of the constraint rod 22. The support spring 23 provides elastic support to the mounting plate 15. An impact rod 24 is provided on the upper side of the mounting plate 15, and the impact rod 24 extends through the movable frame 13. The impact rod 24 is a T-shaped cylindrical rod with threads on its side. A support cylinder 25 is fixedly connected between the side of the impact rod 24 and the top wall of the movable cavity 21. The support cylinder 25 is a corrugated cylinder made of elastic material. A counterweight 26 is provided on the upper side of the impact rod 24. The counterweight 26 is a round counterweight block. A mating cavity 261 is formed on the lower side of the counterweight 26, and the mating cavity 261 is threaded onto the side of the impact rod 24. The mating cavity 261 is a U-shaped cylindrical threaded groove. An inner cavity 241 is formed on the bottom side of the impact rod 24, and the inner cavity 241 is a T-shaped cylindrical groove. A trigger rod 242 is movably installed inside the inner cavity 241, and the trigger rod 242 extends out of the inner cavity 241 to the mating cavity 26. Inside 61, the trigger rod 242 is a "T"-shaped round rod. A connecting cylinder 243 is fixedly connected between the side of the trigger rod 242 and the upper side of the impact rod 24. The connecting cylinder 243 is movably sleeved on the side of the trigger rod 242. The connecting cylinder 243 is a corrugated cylinder made of elastic material. A nail gun cartridge 27 is snapped into the inner cavity 241 and is attached to the upper side of the mounting plate 15. The nail gun cartridge 27 can be a commonly available nail gun cartridge.

[0027] Specifically, in the event of motor damage or soft ground, manually pulling the counterweight 26 causes the impact rod 24 to deform by compressing the support cylinder 25. Releasing the counterweight 26 allows the impact rod 24 to impact the mounting plate 15 due to its inertia. This, combined with the adjusting rod 14, moves the movable frame 13 downwards, allowing the sampling cylinder to be inserted under the road surface for sampling. Simultaneously, when the impact rod 24 impacts the side of the mounting plate 15, the trigger rod 242 slides downwards under inertia, compressing and deforming the connecting cylinder 243. The impact of 42 triggers the explosive impact of the nail cartridge 27 on its side, and the impact force can enhance the pushing of the mounting plate 15. The usage logic is as follows: when not driven into the road surface, the nail cartridge 27 is installed inside the inner cavity 241. Pulling the counterweight 26 to impact the mounting plate 15 at the same time triggers the nail cartridge 27 to impact the mounting plate 15, so that the sampling tube can be steadily inserted into the road surface. Then the nail cartridge 27 can be replaced for use, or it can be used without installing the nail cartridge 27. The sampling tube can be inserted into the road surface for sampling by the inertial impact of the counterweight 26.

[0028] In summary: The sampling cylinder height is precisely adjusted by the cooperation of the support column 11 of the base frame 1 and the threaded adjusting rod 14 of the movable frame 13. Under normal operating conditions, the motor drives the sampling cylinder to rotate, and the adjusting rod 14 controls the downward drilling. When the motor fails or the ground is soft, auxiliary component 2 is activated: the counterweight 26 is manually lifted, driving the impact rod 24 to apply impact force to the mounting plate 15. Simultaneously, the trigger rod 242 inertially triggers the nail cartridge 27 to explode, and the dual force propels the sampling cylinder to quickly penetrate the road surface. The support spring 23 and the constraint rod 22 ensure the mounting plate 15 returns to its original position. The replaceable design of the nail cartridge 27 meets the needs of multiple impacts, achieving seamless switching between electric and manual modes.
