Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a foundation probing device. Background Technology

[0002] Probing is an engineering test used in construction projects. After the foundation pit has been excavated to the design elevation, the soil layer below the bottom of the pit is probed to determine its hardness. Typically, a 10-kilogram drop hammer is used to drive the probe into the soil from a fixed height. The number of blows required to penetrate 30 centimeters is recorded, and this data is used to determine the soil's hardness.

[0003] Currently, most conventional probing machines only have one drop hammer. After the drop hammer is raised to a certain height by a lifting mechanism, it is allowed to fall freely to strike the probe, completing one hammer strike. In the whole process, the time it takes for the drop hammer to complete the hammer strike to the highest point is relatively long, which reduces the construction efficiency. Therefore, a high-efficiency foundation probing construction device is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a foundation probing construction device that improves construction efficiency by setting two drop hammers to alternately strike the ground.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foundation probing device, comprising

[0007] The support mechanism includes a horizontally arranged base frame, two side frames vertically fixed in the middle of the base frame, and a crossbeam horizontally fixed at the upper end of the two side frames, with a core rod installed at the center of the crossbeam;

[0008] A chisel hammer mechanism is installed inside a support mechanism. The chisel hammer mechanism includes a vertical tube that is rotatably installed between the bottom frame and the crossbeam. A lifting frame slides on the two vertical tubes. An inner drop hammer is slidably mounted on the lifting frame through the core rod. An outer drop hammer is coaxially mounted on the outer side of the inner drop hammer. A smooth rod is vertically fixed inside the lifting frame. The smooth rod is slidably connected to the outer drop hammer through the lifting frame. Two hammer-pulling assemblies are installed inside the lifting frame. The two hammer-pulling assemblies push the inner drop hammer and the outer drop hammer to rise respectively.

[0009] The probing mechanism is slidably mounted on the core rod and located below the inner and outer drop hammers.

[0010] Preferably, the lower end of the lifting frame is provided with a hollow hole corresponding to the probing mechanism.

[0011] Preferably, the inner drop hammer includes

[0012] The inner tube hammer is slidably mounted on the core rod.

[0013] Side wing plate one, vertically fixed to the outside of the inner tube hammer;

[0014] The first pivot is fixed to the upper end of the first side wing plate.

[0015] Preferably, the outer drop hammer includes

[0016] The outer tube hammer is coaxially arranged with the inner tube hammer and slides on the smooth rod;

[0017] Side wing plate two is vertically fixed to the outside of the outer tube hammer;

[0018] The second pivot is fixed to the upper end of the second side wing plate;

[0019] The opening slots are set on the outer tube hammers on both sides away from the side wing plates and correspond to the side wing plates.

[0020] Preferably, the hammer assembly includes

[0021] The power shaft is rotatably mounted on the lifting frame;

[0022] The lever is fixed to the side of the power shaft;

[0023] A sleeve is fitted onto the actuating lever;

[0024] The lever is fixed on the sleeve and has a curved section at the end away from the power shaft.

[0025] A spring is disposed between the power shaft and the sleeve.

[0026] Preferably, the curved section of the dial plate has a V-shaped opening.

[0027] Preferably, the probe mechanism includes

[0028] The probe rod has a pointed tip at the lower end;

[0029] A diameter-enlarging seat is provided at the upper end of the probe rod;

[0030] The impact plate is fixed to the upper end of the diameter-increasing seat.

[0031] Preferably, the foundation probing device further includes a probe extraction mechanism, the probe extraction mechanism comprising:

[0032] A transverse beam is fixed to the upper end of the core rod;

[0033] Two threaded columns are provided, and the two threaded columns are respectively threadedly connected to two vertical pipes. The horizontal beam is fixed to the upper end of the two threaded columns.

[0034] The cylindrical head is coaxially fixed to the lower end of the core rod and slides within the probe rod.

[0035] Preferably, each of the four corners of the base frame is vertically fixed with a support pipe seat, the lower end of each of the four support pipe seats is fixed with a bottom ring, and a moving mechanism is telescopically installed inside each of the four support pipe seats.

[0036] Preferably, the moving mechanism includes

[0037] There are four mounting pipes, and the four mounting pipes slide through the four branch pipe seats respectively;

[0038] The flat plate bracket is fixed to the upper end of the four mounting tubes;

[0039] The system has four casters, which are mounted on four mounting tubes for rotation.

[0040] There are two rotating wheels, which are respectively installed at the front and rear ends of the bottom frame and are synchronously connected for transmission.

[0041] Two threaded rods are provided, which are coaxially fixed to the upper ends of the two rotating wheels and are threadedly connected to the plate frame.

[0042] The present invention has the following beneficial effects:

[0043] In actual use, the two hammer-pulling assemblies respectively pull the inner and outer hammers upwards. After rising to a certain height, the hammer-pulling assemblies separate from the inner or outer hammers, allowing the inner and outer hammers to alternately fall freely and strike the probing mechanism. Thus, compared to single-hammer hammering operations, the alternating hammering of the inner and outer hammers means that while one hammer is finishing its strike and being raised to its highest point, the other hammer has already completed its strike, greatly shortening the time interval between two strikes and improving construction efficiency. In addition, by setting up a probe-pulling mechanism, it can be ensured that the probe rod will not deform when it is pulled out. Attached Figure Description

[0066] Combination Figure 1-5This invention provides a foundation probing construction device, including a support mechanism 1. The support mechanism 1 includes a horizontally arranged base frame 11, two side frames 12 vertically fixed in the middle of the base frame 11, and a horizontal beam 13 horizontally fixed to the upper ends of the two side frames 12. A core rod 14 is installed at the center of the horizontal beam 13. A drill hammer mechanism 2 is installed inside the support mechanism 1. The drill hammer mechanism 2 includes vertical pipes 21 vertically rotatably installed between the base frame 11 and the horizontal beam 13, and lifting frames sliding on the two vertical pipes 21. 22, the core rod 14 passes through the lifting frame 22 and an inner drop hammer 23 is slidably mounted on it. An outer drop hammer 24 is coaxially mounted on the outer side of the inner drop hammer 23. A smooth rod 25 is vertically fixed inside the lifting frame 22. The smooth rod 25 and the outer drop hammer 24 are slidably connected through it. Two hammer-pulling assemblies 26 are installed inside the lifting frame 22. The two hammer-pulling assemblies 26 respectively push the inner drop hammer 23 and the outer drop hammer 24 to rise. The probing mechanism 3 is slidably mounted on the core rod 14 and is located below the inner drop hammer 23 and the outer drop hammer 24.

[0067] Specifically, the base frame 11, two side frames 12, and crossbeam 13 form a frame, and an installation space is formed within the frame for installing the vertical pipes 21, keeping the two vertical pipes 21 in a vertical state, and allowing the lifting frame 22 installed on the two vertical pipes 21 to move up and down within the frame. The core rod 14 is located at the center of the installation space and extends vertically downward from the crossbeam 13, passing through the drill hammer mechanism 2 and the probing mechanism 3 in sequence, thereby limiting the probing mechanism 3. At the same time, it ensures that the inner hammer 23 and the outer hammer 24 can land directly above the probing mechanism 3 when they alternately hammer, ensuring the hammering effect. The lifting frame 22 is also equipped with a smooth rod 25 to limit the outer hammer 24, ensuring that the hammer-pulling assembly 26 can push the outer hammer 24 to move up and down reciprocally.

[0068] In actual use, the support mechanism 1 is placed at the construction position, and the lower end of the probing mechanism 3 is aligned with the probing point. The lower end of the lifting frame 22 is pressed against the upper end of the probing mechanism 3. Then, the two hammer-pulling assemblies 26 are activated, which respectively pull the inner hammer 23 and the outer hammer 24 upward. After rising to a certain height, the hammer-pulling assembly 26 separates from the inner hammer 23 or the outer hammer 24, allowing the inner hammer 23 and the outer hammer 24 to alternately fall freely and strike the probing mechanism 3. Figure 6-7 As shown, in contrast to a single hammer strike, the inner hammer 23 and the outer hammer 24 are set to strike alternately. When one hammer finishes its strike and is raised to its highest point, the other hammer has already completed one strike, which greatly shortens the time interval between the two strikes and improves construction efficiency.

[0069] It is worth noting that after the lower end of the probing mechanism 3 is aligned with the probing point, the level of the support mechanism 1 needs to be adjusted to ensure that the probing mechanism 3 is perpendicular to the ground.

[0070] Combination Figure 5In some embodiments, the lower end of the lifting frame 22 is provided with a hollow hole corresponding to the probe mechanism 3.

[0071] Specifically, the lifting frame 22 is also a frame structure with perforated holes on its lower side plate. The perforated holes allow the inner hammer 23 and outer hammer 24 to strike the probe mechanism 3 directly when they fall, ensuring the hammering effect of the inner hammer 23 and outer hammer 24 on the probe mechanism 3. Compared to the hammer striking the lifting frame 22 and then transferring the hammering force to the probe mechanism 3, this reduces the influence of friction between the lifting frame 22 and the vertical pipe 21.

[0072] Combination Figure 8 In some embodiments, the inner drop hammer 23 includes an inner tube hammer 231 that slides on the core rod 14; a side wing plate 232 that is vertically fixed to the outside of the inner tube hammer 231; and a lever 233 that is fixed to the upper end of the side wing plate 232.

[0073] Specifically, the inner tube hammer 231 is in the shape of a tube, and its inner hole is fitted onto the core rod 14, which limits the inner tube hammer 231 to only be able to move up and down. At the same time, through the radial extension of the side wing plate 232 on the outside of the inner tube hammer 231, the deflector 233 is installed and fixed away from the inner tube hammer 231, which facilitates cooperation with the hammer deflector assembly 26. When the hammer deflector assembly 26 rotates, the inner tube hammer 231 can be driven to slide upward along the core rod 14 by deflecting the deflector 233. At the same time, after the hammer deflector assembly 26 separates from the deflector 233, the inner tube hammer 231 falls freely along the core rod 14 and strikes the upper end of the probing mechanism 3.

[0074] Combination Figure 9 In some embodiments, the outer drop hammer 24 includes an outer tube hammer 241 coaxially arranged with the inner tube hammer 231 and sliding on the guide rod 25; a second side wing plate 242 is vertically fixed to the outside of the outer tube hammer 241; a second detonator 243 is fixed to the upper end of the second side wing plate 242; and an opening slot 244 is provided on the outer tube hammer 241 on the side away from the second side wing plate 242 and corresponds to the first side wing plate 232.

[0075] Specifically, the outer tube hammer 241 is in the shape of a tube, and its inner diameter is slightly larger than that of the inner tube hammer 231, so that the outer tube hammer 241 can be coaxially sleeved on the outside of the inner tube hammer 231. At the same time, it has an opening slot 244 on one side to facilitate the passage of the side wing plate 232, so as not to affect the alternating lifting and hammering operation of the inner hammer 23 and the outer hammer 24. The side wing plate 242 also extends radially at the outer end of the outer tube hammer 241, providing an installation position for the second detonator 243. It is also convenient to cooperate with another hammer assembly 26. When the hammer assembly 26 rotates, the outer tube hammer 241 can be driven to slide upward along the smooth rod 25 by detonating the second detonator 243. At the same time, after the hammer assembly 26 separates from the second detonator 243, the outer tube hammer 241 falls freely along the smooth rod 25 and hammers the upper end of the probing mechanism 3.

[0076] It should be noted that by sequentially mounting the outer tube hammer 241 and the inner tube hammer 231 in a tube shape and coaxially with the core rod 14, it is easy to ensure that the center of gravity of the outer tube hammer 241 and the inner tube hammer 231 is infinitely close to the central axis. Thus, when the hammer is dropped, it ensures that its center of gravity is infinitely close to the central axis of the probing mechanism 3, and ensures that the probing mechanism 3 will not tip over after being hammered and inserted into the ground.

[0077] Combination Figure 9 In some embodiments, the hammer assembly 26 includes a power shaft 261 rotatably mounted on the lifting frame 22; a toggle lever 262 fixed to the side of the power shaft 261; a sleeve 263 slidingly mounted on the toggle lever 262; a toggle plate 264 fixed to the sleeve 263 and having a curved section at the end away from the power shaft 261; and a spring 265 disposed between the power shaft 261 and the sleeve 263.

[0078] Specifically, the power shaft 261 is horizontally mounted on the lifting frame 22, and a first motor is installed on the lifting frame 22 to drive the power shaft 261, causing the power shaft 261 to drive the actuating lever 262 to rotate in the plane of the lifting frame 22. When the actuating lever 262 drives the actuating plate 264 to rotate to the position of the first actuating post 233 or the second actuating post 243 via the sleeve 263, the actuating plate 264 will push the first actuating post 233 or the second actuating post 243, causing the inner tube hammer 231 or the outer tube hammer 241 to slide upward. As the inner tube hammer 231 or the outer tube hammer 241 moves upward, the first actuating post 233 or the second actuating post 243 will gradually approach the power shaft 261, thereby forming a counterbalance to the actuating plate 264. The pressure causes the lever 264 to slide on the lever 262 via the sleeve 263, compressing the spring 265. As the inner tube hammer 231 or the outer tube hammer 241 continues to move upward, the first lever 233 or the second lever 243 will gradually move away from the power shaft 261. As a result, the spring 265 will push the sleeve 263 to drive the lever 264 to keep the first lever 233 or the second lever 243 pressed against it, causing the inner tube hammer 231 or the outer tube hammer 241 to move upward until the inner tube hammer 231 or the outer tube hammer 241 rises to the highest point. Then, the lever 264 will separate from the first lever 233 or the second lever 243, allowing the inner tube hammer 231 or the outer tube hammer 241 to fall freely and complete the hammering operation.

[0079] Each power shaft 261 has two parallel actuating rods 262 fixed on it, and a retaining ring is provided at the end of the actuating rod 262 away from the power shaft 261 to limit the sleeve 263 and prevent the sleeve 263 from being pushed away from the actuating rod 262 by the spring 265. When the sleeve 263 slides on the two actuating rods 262 toward the power shaft 261, the side wing plate 1 232 or the side wing plate 242 near the power shaft 261 can enter between the two actuating rods 262 to avoid interference.

[0080] Meanwhile, by providing a curved section at the end of the lever plate 264 away from the power shaft 261, the lever plate 264 can push the first lever 233 or the second lever 243 to the highest point through the curved section, and then slide away from the first lever 233 or the second lever 243.

[0081] In addition, preferably, in some embodiments, the side wing plate 232 or the side wing plate 242 is far from the edge of the core rod 14 and has an inclined shape that moves from top to bottom toward the core rod 14, so that the rotating plate 264 can slide over the side wing plate 232 or the side wing plate 242 to press against the pivot 233 or the pivot 243, so that the inner tube hammer 231 or the outer tube hammer 241 rises.

[0082] Furthermore, in some embodiments, the curved segment of the dial 264 is provided with a V-shaped opening 266.

[0083] In actual use, in order to ensure that the inner tube hammer 231 and the outer tube hammer 241 alternately rise and fall to hammer, it is necessary to ensure that the side wing plate 232 and the opening slot 244 are aligned. However, when the inner tube hammer 231 or the outer tube hammer 241 completes the hammering, there will be a certain degree of vibration, which will cause the inner tube hammer 231 to rotate around the core rod 14 as the axis and the outer tube hammer 241 to rotate around the smooth rod 25 as the axis. This will cause the side wing plate 232 and the opening slot 244 to be unable to keep aligned, and even the inner diameter of the outer tube hammer 241 may not correspond to the outer diameter of the inner tube hammer 231, which will prevent the two from alternating rise and fall and affect the construction operation.

[0084] Based on this, the curved section of the lever 264 away from the power shaft 261 is extended, and a V-shaped opening 266 is provided in the middle of the distal end. This allows the lever 264 to first contact the side wing 232 or side wing 242 through the V-shaped opening 266 when it rotates to the side wing 232 or side wing 242. At this time, the hammer has just finished its hammering vibration, and the deflected side wing 232 or side wing 242 will first contact the side of the V-shaped opening 266. The upward rotation of the lever 264 causes the side of the V-shaped opening 266 to slide at the edge of the first side wing plate 232 or the second side wing plate 242, which will center and guide the first side wing plate 232 or the second side wing plate 242. After the first side wing plate 232 or the second side wing plate 242 automatically returns to its original position, the lever 1 or the lever 243 is pushed to raise the inner tube hammer 231 or the outer tube hammer 241, ensuring that the inner tube hammer 231 and the outer tube hammer 241 rise and fall alternately, and quickly complete the construction operation.

[0085] Combination Figure 11 In some embodiments, the probing mechanism 3 includes a probing rod 31 with a pointed end at the lower end; a diameter-enlarging seat 32 disposed at the upper end of the probing rod 31; and an impact plate 33 fixed at the upper end of the diameter-enlarging seat 32.

[0086] Specifically, the probe rod 31 is straight with a pointed tip at the bottom for easy insertion into the ground. The diameter of the expanding seat 32 is larger than that of the probe rod 31 and is located at the upper end of the probe rod 31 to facilitate the transmission of hammering force to the probe rod 31, allowing the probe rod 31 to be inserted into the ground axially. The impact plate 33 is a circular plate structure, coaxially fixed at the upper end of the expanding seat 32, used to receive the hammering of the inner tube hammer 231 and the outer tube hammer 241. At the same time, the diameter of the impact plate 33 is larger than the perforated hole at the lower end of the lifting frame 22, so that the inner tube hammer 231 and the outer tube hammer 241 can directly hammer the impact plate 33 through the perforated hole, ensuring the hammering effect while the impact plate 33 can support the lifting frame 22, so that the lifting frame 22 is always above the impact plate 33, ensuring that the hammering height of the inner tube hammer 231 and the outer tube hammer 241 is consistent during free fall.

[0087] Combination Figure 2 , Figure 5 , Figure 12 In some embodiments, the foundation probing construction device further includes a probing mechanism 4, which includes a horizontal pulling beam 41 fixed to the upper end of the core rod 14; two threaded columns 42 are provided, and the two threaded columns 42 are respectively threadedly connected to two vertical pipes 21, and the horizontal pulling beam 41 is fixed to the upper end of the two threaded columns 42; a cylindrical head 43 is coaxially fixed to the lower end of the core rod 14 and slides within the probing rod 31.

[0088] Specifically, the upper ends of the two vertical tubes 21 are coaxially fixed with transmission wheels, and the center of the two transmission wheels is provided with threaded holes. The threads on the outer surface of the threaded column 42 are engaged with the threaded holes to form a threaded connection between the threaded column 42 and the vertical tube 21. The diameter of the cylindrical head 43 is larger than the diameter of the core rod 14. The center of the impact plate 33 is provided with a central hole that is engaged with the diameter of the core rod 14. The probe rod 31 is provided with a core hole that is engaged with the diameter of the cylindrical head 43. Through the sliding of the cylindrical head 43 and the core hole, and the sliding of the core rod 14 and the central hole, the coaxial positioning of the core rod 14 and the probe mechanism 3 is formed.

[0089] When the hammer-driven probing mechanism 3 is inserted into the ground, the cylindrical head 43 is located at the lower end and does not affect the probing mechanism 3. When the probing hole construction is completed and the probing rod 31 is pulled out of the ground, the second motor installed on the crossbeam 13 is started to synchronously drive the two transmission wheels, so that the two vertical tubes 21 rotate synchronously on the crossbeam 13, and then rotate synchronously relative to the two threaded columns 42. Thus, through the threaded engagement, the two threaded columns 42 rise synchronously in the two vertical tubes 21, and then drive the core rod 14 to move upward through the crossbeam 41. When the cylindrical head 43 presses against the impact plate 33, as the core rod 14 continues to rise, the cylindrical head 43 will push the impact plate 33 to rise, and then drive the probing rod 31 to move upward until it is pulled out of the ground. During this process, the probing rod 31 is initially inserted into the ground downward along the core rod 14. Finally, the probing rod 31 is pulled out by the axial rise of the core rod 14, which is equivalent to rising along the core rod 14, thus greatly avoiding the deformation of the probing rod.

[0090] It should be noted that the cylindrical head 43 and the core rod 14 are connected by threads. The diameter-increasing seat 32 is hollow inside and has multiple through holes on its outer side, which facilitates the installation and removal of the cylindrical head 43 and the core rod 14 through the through holes.

[0091] Combination Figure 3 , Figure 4 , Figure 13 In some embodiments, each of the four corners of the base frame 11 is vertically fixed with a support pipe seat 15, and the lower end of each of the four support pipe seats 15 is fixed with a bottom ring 16. A moving mechanism 5 is telescopically installed inside each of the four support pipe seats 15.

[0092] Specifically, the four branch pipe seats 15 form a support for the bottom frame 11, which makes it easier to adjust the horizontal state of the bottom frame 11 during operation. At the same time, the bottom ring 16 increases the contact area between the branch pipe seats 15 and the ground, ensuring the overall stability.

[0093] When the device needs to be moved to perform the next drilling operation, the control moving mechanism 5 slides out from the four branch pipe seats 15 and replaces the bottom ring 16 to contact the ground, which can quickly move the device to the construction position. This improves the efficiency of the moving device. At the same time, the ability of the moving mechanism 5 to extend and retract within the four branch pipe seats 15 ensures the stability of the device operation.

[0094] Combination Figure 13 In some embodiments, the moving mechanism 5 includes four mounting tubes 51, which slide through four support pipe seats 15 respectively; a flat plate frame 52 is fixed to the upper end of the four mounting tubes 51; four casters 53 are rotatably mounted on the four mounting tubes 51 respectively; two rotating wheels 54 are rotatably mounted at the front and rear ends of the bottom frame 11 respectively, and the two rotating wheels 54 are synchronously connected; and two threaded rods 55 are coaxially fixed to the upper end of the two rotating wheels 54 and are threadedly connected to the flat plate frame 52.

[0095] Specifically, the lower end of the branch pipe seat 15 is hollowed out to provide space for the universal wheel 53, so that the universal wheel 53 can slide into the hollowed-out space, forming the retraction of the universal wheel 53, so that the whole device can contact the ground by relying on the bottom ring 16 at the lower end of the four branch pipe seats 15.

[0096] When the device needs to be moved, the third motor installed on the base frame 11 is started to drive one of the rotating wheels 54, which in turn drives the other rotating wheel 54. The two rotating wheels 54 rotate synchronously, which in turn drives the two threaded rods 55 to rotate synchronously. Utilizing the threaded engagement between the threaded rods 55 and the flat plate frame 52, the flat plate frame 52 will remain horizontal and descend on the two threaded rods 55. This causes the four mounting tubes 51 to slide downwards and insert into the four support tube seats 15 at the same time, thereby driving the four universal wheels 53 to move out of the hollow space at the lower end of the support tube seat 15 and replace the bottom ring 16 to contact the ground. At this time, the device is pushed, allowing the device to move quickly in any direction via the four universal wheels 53, thereby improving the device's movement efficiency.

[0097] The two rotating wheels 54 are connected by a synchronous belt or chain, which avoids the probe rod 31 to prevent interference.

[0098] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
