Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a protective hammer-type piling equipment. Background Art

[0002] Pile drivers are needed during construction. There are many types of pile drivers, one of which is a hammer pile driver. The counterweight is lifted to a certain height and then released, and the gravitational potential energy of the counterweight is used to hammer the pile body to achieve piling.

[0003] In the prior art, a pile driver consists of a machine body, a hammer arm, and a hammer head. After the machine body lifts the pile to an upright position relative to the ground, the hammer arm drives the hammer head to continuously hammer the pile, driving it into the ground. However, the underground soil structure is complex, with sand particles fine at the top and coarse at the bottom. As the depth of the sand increases, the resistance to pile driving increases, and the penetration rate decreases sharply, which can easily cause a sudden increase in the pile's rebound force on the hammer head. Continuously using the same hammer force can easily damage the pile and the hammer head. Summary of the Invention

[0004] In order to improve the above problems, the present application provides a protective hammer piling equipment.

[0005] The present application provides a protective hammer piling device that adopts the following technical solutions:

[0006] A protective hammer piling device comprising:

[0007] body;

[0008] A limiting assembly, comprising a limiting sleeve and a limiting bearing block, wherein the limiting sleeve is slidably connected to the body, the limiting bearing block is disposed in the limiting sleeve, and the limiting sleeve is sleeved on the end of the pile column, with one end of the pile column abutting against the limiting bearing block;

[0009] A hammer block, which slides in the limiting sleeve and abuts against a side of the limiting bearing block facing away from the pile column;

[0010] A lifting assembly is provided on the machine body, and includes a lifting drive source and a lifting member. The lifting drive source is used to drive the lifting member to move upward, and the lifting member is used to carry the hammer block for lifting;

[0011] The sliding assembly comprises a sliding drive source and a sliding baffle, the sliding drive source being arranged on the outer wall of the limiting sleeve, the limiting sleeve being provided with a docking long hole along its own length direction, the sliding baffle abutting the outer wall of the limiting sleeve, and the length of the sliding baffle being smaller than the length of the docking long hole, the sliding drive source drives the sliding baffle to slide, and when the sliding baffle slides downward, a first docking interface is formed between the upper end of the sliding baffle and the limiting sleeve; when the sliding baffle slides upward, a second docking interface is formed between the lower end of the sliding baffle and the limiting sleeve; the first docking interface and the second docking interface are both used for allowing the hammer block to enter the limiting sleeve;

[0012] A positioning assembly, comprising a positioning clamping block and a penetration meter. The positioning clamping block is provided on the machine body and is used to clamp and fix the pile. The penetration meter is provided on the positioning clamping block and is used to detect the penetration depth of the pile.

[0013] The penetration meter is electrically connected to the sliding drive source, and the penetration meter transmits a signal to the sliding drive source, and the sliding drive source receives the signal to drive the sliding baffle to slide.

[0014] By adopting the above technical solution, after the pile is hoisted to a vertical state, the pile is clamped and fixed by the positioning clamp to keep it vertical, and the hammer block enters the limiting sleeve through the first pair of interfaces to hammer the limiting bearing block, thereby achieving hammering of the pile and reducing direct damage to the pile itself caused by the hammer block; when the penetration meter detects that the penetration depth of the pile does not meet the preset detection range, the penetration meter transmits a signal to the sliding drive source, and the sliding drive source drives the sliding baffle to move upward to block the first pair of interfaces, while the second pair of interfaces is opened, so that the next hammer block enters the limiting sleeve through the second pair of interfaces, reducing the energy storage of the hammer block, thereby reducing the hammering force on the pile, and at the same time reducing the rebound force caused by the pile on the hammer block, reducing the damage to the pile and the hammer block itself caused by excessive hammering force and small penetration.

[0015] Preferably, the positioning assembly also includes a positioning clamp rod, which is slidably connected to the machine body, and the positioning clamp block is detachably connected to the end of the positioning clamp rod away from the machine body by a bolt. The positioning clamp block is provided with a detection connection groove, and the detection connection groove is for placing a penetration meter.

[0016] By adopting the above technical solution, after the positioning clamps are brought close to each other and clamp the pile, the penetration meter is set to an initial state and placed in the detection connection groove. When the pile begins to sink and penetrate, the penetration meter can detect the penetration depth of the pile.

[0017] Preferably, the lifting assembly also includes a lifting column, which is relatively fixed to the limiting sleeve, and the lifting column is provided with a lifting groove along its own length direction. The lifting column is located in the lifting groove and is rotatably connected to a lifting screw. The lifting drive source is a lifting motor, and one end of the lifting screw is coaxially fixedly connected to the output shaft of the lifting motor. The lifting member includes a connecting block, which is threadedly connected to the lifting screw and is located in the lifting groove and moves.

[0018] By adopting the above technical solution, the lifting motor starts to drive the lifting screw to rotate, and the lifting screw rotates to drive the connecting block to move upward along the lifting chute, thereby realizing the lifting of the hammer block, which is convenient for the hammer block to store energy itself.

[0019] Preferably, a docking outlet is provided on the limiting sleeve, and the lifting member further comprises a connecting plate, which is slidably connected to the connecting block. When the connecting plate extends into the docking outlet, the hammer block is located thereon.

[0020] By adopting the above technical solution, the connecting block moves downward to the docking outlet, the connecting plate extends out and docks with the limit bearing block, making it easier for the hammer block to be moved out of the limit sleeve.

[0021] Preferably, a plurality of inserting strips are provided at one end of the connecting plate away from the connecting block, and a plurality of inserting holes are opened on the limiting bearing block, and the positions and numbers of the inserting holes correspond one-to-one to the inserting strips.

[0022] By adopting the above technical solution, the hammer block falls on the limit bearing block. When the connecting plate extends, the driving strip is inserted into the insertion hole, so that the strip is against the bottom of the hammer block. When the connecting plate contracts, the strip is convenient for lowering the hammer block and taking it away from the limit sleeve.

[0023] Preferably, it also includes a pushing component, which includes a pushing hydraulic cylinder and a pushing plate. The pushing hydraulic cylinder is fixedly connected to the outside of the limiting sleeve, and the pushing plate is fixedly connected to the piston rod of the pushing hydraulic cylinder. A placement groove for the push plate is opened in the second sleeve.

[0024] By adopting the above technical solution, when the insertion strip is inserted into the insertion hole, the hydraulic cylinder is started, driving the push plate to move away from the placement slot, and pushing the hammer block to move further onto the insertion strip, so that when the connecting plate contracts, the hammer block is driven to move away from the limiting sleeve more smoothly, making it easier for the subsequent connecting block to carry the hammer block up and move.

[0025] Preferably, the side of the connecting plate away from the connecting block is rotatably connected to a lifting plug plate, the telescopic insert is fixedly connected to the side of the lifting plug plate away from the connecting plate, and limiting vertical rods are provided on opposite sides of the lifting plug plate.

[0026] By adopting the above technical solution, when the connecting block carries the connecting plate and the hammer block and moves upward to the first docking interface or the second docking interface, the connecting plate extends, so that the end of the insert extends into the limiting sleeve. At this time, the lifting insert plate rotates downward relative to the connecting plate, so that the hammer block slides into the limiting sleeve under the action of its own gravity to hammer the pile column.

[0027] Preferably, the sliding drive source is a sliding motor, the end of the output shaft of the sliding motor is fixedly connected to a sliding gear, the sliding baffle is provided with a sliding gear row, and the sliding gear row is engaged with the sliding gear.

[0028] Preferably, it also includes a linkage component, which includes a linkage rod and a linkage block. One end of the linkage rod is hinged to the end of the sliding baffle, and the end of the linkage rod away from the sliding baffle is hinged to the linkage block. The linkage block is slidably connected to the lifting column in the vertical direction.

[0029] By adopting the above technical solution, when the sliding motor drives the sliding baffle to move, the linkage rod drives the linkage block to slide up and down along the lifting column, thereby limiting the rising position of the connecting block. When the connecting block abuts against the linkage block, the connecting block stops rising, thereby facilitating the alignment of the hammer block with the first pair of interfaces or the second pair of interfaces.

[0030] Preferably, a pressure sensor is provided on the linkage block, and the pressure sensor is electrically connected to the lifting motor. The connection block moves upward along the lifting chute. When the connection block abuts against the pressure sensor, the pressure sensor detects the pressure and transmits a signal to the lifting motor.

[0031] By adopting the above technical solution, when the connecting block rises and moves to abut against the linkage block, the pressure sensor detects the abutting force exerted by the connecting block on it, and the pressure sensor sends a signal to the lifting motor, which stops immediately after receiving the signal. At this time, the connecting block carries the hammer block to the corresponding first pair of interfaces or the second pair of interfaces, which is beneficial to improving the accuracy of the rising position of the hammer block and the consistency of the rising position of the hammer block during multiple continuous hammering.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. Through the arrangement of the penetration meter, the docking slot, and the sliding baffle, when the penetration meter detects that the pile penetration depth does not meet the preset detection range, the penetration meter transmits a signal to the sliding drive source, which drives the sliding baffle upward, blocking the first pair of interfaces and simultaneously opening the second pair of interfaces, allowing the next hammer block to enter the limiting sleeve through the second pair of interfaces, reducing the stored energy of the hammer block, thereby reducing the hammer force on the pile and the rebound force caused by the pile on the hammer block, thereby reducing damage to the pile and the hammer block itself caused by excessive hammer force and low penetration;

[0034] 2. By lifting the insertion plate, the insertion strip and the push plate, the hammer block falls on the limit bearing block. When the connecting plate is extended, the insertion strip is driven to be inserted into the insertion hole. When the insertion strip is extended into the insertion hole, the insertion strip is pressed against the bottom of the hammer block, pushing the hydraulic cylinder to start, driving the push plate to move away from the placement slot, and pushing the hammer block further to move onto the insertion strip. When the connecting plate contracts, the hammer block is driven to move away from the limit sleeve more smoothly, making it easier for the subsequent connecting block to carry the hammer block to move upward.

[0042] The following is combined with Figure 1-6 This application is described in further detail.

[0043] The embodiment of the present application discloses a protective hammer-type piling device, such as Figure 1 As shown, it includes a body 1, on which are provided a limiting assembly 3, a hammer block 4, a lifting assembly 5 and a positioning assembly 6. The positioning assembly 6 is used to clamp the pile column 10, and the limiting assembly 3 is used to cooperate with the positioning assembly 6 to limit the position of the pile column 10. The lifting assembly 5 is used to drive the lifting of the hammer block 4. After the hammer block 4 is lifted, the corresponding gravitational potential energy is stored, and its own potential energy is used to hammer the pile column 10, thereby realizing the penetration of the pile column 10 into the ground.

[0044] like Figure 1 and 2 As shown, the positioning assembly 6 includes a positioning clamping rod 61 and a positioning clamping block 62. Two positioning clamping rods 61 are provided, and both positioning clamping rods 61 are slidably connected to the lower portion of the machine body 1. The positioning clamping blocks 62 correspond one to one with the positioning clamping rods 61. The positioning clamping blocks 62 are detachably connected to the end of the positioning clamping rod 61 away from the machine body 1 via bolts. Each positioning clamping block 62 is semicircular in shape. The two positioning clamping blocks 62 move toward each other to clamp and position the lower end of the pile 10, so that the pile 10 remains in a vertical position. The positioning clamping blocks 62 can be replaced and adjusted according to the diameter of the pile 10 to be constructed.

[0045] like Figure 1 and 3As shown, the body 1 is slidably connected to a sliding platform 11. The limiting assembly 3 includes a limiting sleeve 31 and a limiting block 32. The limiting sleeve 31 is fixedly connected to the sliding platform 11, and the limiting block 32 is fixedly connected to the limiting sleeve 31. The limiting block 32 divides the limiting sleeve 31 into two parts, an upper part and an lower part. The lower end of the limiting block 32 is a first sleeve 311, and the upper end of the limiting block 32 is a second sleeve 312. The end of the pile 10 away from the positioning clamp 62 extends into the first sleeve 311 and abuts against the limiting block 32. The inner wall of the limiting sleeve 31 contacts the outer wall of the pile 10. The limiting sleeve 31 and the positioning clamp 62 further cooperate to keep the pile 10 perpendicular to the ground, facilitating the angular stability of the pile 10 during subsequent hammering. The second sleeve 312 is provided with a docking outlet 3123 near the limiting bearing block 32 , and the docking outlet 3123 is used for the hammer block 4 to move out of the second sleeve 312 .

[0046] like Figure 2 、 4 As shown in Figure 5, the second sleeve 312 also includes a hammer block 4. The hammer block 4 is located in the second sleeve 312 and falls by its own gravity. When the hammer block 4 falls, it hammers the limit bearing block 32, thereby generating a hammering force on the pile column 10. Under the action of the hammering force, the pile column 10 continuously penetrates the ground. The second sleeve 312 has a long docking hole 3121 opened along its own length. The second sleeve 312 is also provided with a sliding assembly 8. The sliding assembly 8 includes a sliding drive source and a sliding baffle 82. The sliding drive source is a sliding motor 81. The sliding motor 81 is fixedly connected to the outer wall of the limit sleeve 31. The output shaft end of the sliding motor 81 is coaxially fixedly connected to the sliding gear 811. The sliding baffle 82 is fixedly connected to the sliding gear row 821. The sliding gear 811 meshes with the sliding gear row 821. The sliding baffle 82 is attached to the outer wall of the second sleeve 312. The sliding baffle 82 is used to block the docking elongated hole 3121 and is shorter than the docking elongated hole 3121. When the sliding motor 81 is activated and drives the sliding baffle 82 downward, a first docking interface 83 is formed between the upper end of the sliding baffle 82 and the second sleeve 312. When the sliding motor 81 drives the sliding baffle 82 upward, a second docking interface 84 is formed between the sliding baffle 82 and the second sleeve 312. Both the first docking interface 83 and the second docking interface 84 are used to allow the hammer block 4 to enter the second sleeve 312 to hammer the limit bearing block 32.

[0047] like Figure 1As shown, the machine body 1 is equipped with a built-in sliding drive (not shown) for driving the sliding platform 11 to move upward and downward relative to the machine body 1. A penetration meter 9 is fixedly connected to the positioning clamp 62 and is electrically connected to the sliding drive of the sliding platform 11. According to the preset PLC program, the penetration meter 9 can detect the penetration depth range of the pile 10 based on the force of the hammer. The hammer block 4 drops onto the limit bearing block 32, which transmits force to the pile 10, driving the pile 10 downward. If the depth of the pile 10 falls within the set penetration depth range, the penetration meter 9 sends a signal to the sliding drive each time it detects the pile 10 sinking. Upon receiving the signal, the sliding drive then drives the sliding platform 11 downward.

[0048] like Figure 5 As shown, the penetration meter 9 is also electrically connected to the sliding motor 81, and the penetration meter 9 transmits a signal to the sliding motor 81. When the hammer block 4 enters the second sleeve 312 from the first docking port 83, the hammer block 4 has a large amount of stored gravitational potential energy. At this time, if the penetration meter 9 detects that the penetration depth of the pile column 10 is within the preset range, it proves that the pile column 10 has penetrated the lower end of the ground smoothly and the piling construction can continue. If the penetration meter 9 detects that the penetration depth of the pile column 10 is less than the preset range, it means that the pile column 10 encountered an obstacle during penetration, such as a large stone. At this time, due to the sudden decrease in the penetration depth of the pile column 10, the rebound force of the pile column 10 on the limit bearing block 32 suddenly increases, and the rebound force on the hammer block 4 increases, which is more likely to cause self-vibration damage to both the pile column 10 and the hammer block 4. After this occurs, the penetration meter 9 sends a signal to the sliding motor 81. Upon receiving the signal, the sliding motor 81 starts, driving the sliding gear 811 to rotate. The sliding gear 811 then drives the sliding gear row 821, which in turn drives the sliding baffle 82 upward. As the sliding baffle 82 moves upward, it blocks the first docking port 83 and opens the second docking port 84. Because the vertical distance between the second docking port 84 and the stop block 32 is smaller than the vertical distance between the first docking port 83 and the stop block 32, when the hammer block 4 enters the second sleeve 312 through the second docking port 84, the gravitational potential energy stored in the hammer block 4 is smaller. When the hammer block 4 falls to hammer, the force exerted on the pile 10 is smaller, and the rebound force exerted by the pile 10 on the hammer block 4 is also relatively small. This allows for continued hammer penetration of the pile 10 while minimizing potential damage to the pile 10 and the hammer block 4 itself.

[0049] like Figure 3 、 5As shown in Figure 6, the lifting assembly 5 includes a lifting drive source, a lifting column 51, and a lifting member 53. The lifting drive source is a lifting motor 52, which is fixedly connected to the sliding platform 11. The lifting column 51 is vertically fixedly connected to the sliding platform 11. The lifting column 51 has a lifting slot 513 along its length. The lifting column 51 is rotatably connected to a lifting screw 511 in the lifting slot 513. One end of the lifting screw 511 is coaxially fixedly connected to the output shaft of the lifting motor 52. The lifting member 53 includes a connecting block 531, a connecting plate 532, a lifting plug 533, and a limiting rod 535. The connecting block 531 is threadedly connected to the lifting screw 511, and the connecting plate 532 is slidably connected to the connecting block 531. The connecting block 531 has a built-in driving source (not shown in the figure) that drives the connecting plate 532 to slide relative to the connecting block 531. The lifting plate 533 is rotatably connected to the end of the connecting plate 532 away from the connecting block 531. The lifting plate 533 incorporates a drive source (not shown) that drives the lifting plate 533 relative to the connecting plate 532. Several inserting bars 534 are integrally formed on the end of the lifting plate 533 away from the connecting plate 532. The retaining block 32 is provided with several insertion holes 321 on the side facing the second sleeve 312 for the inserting bars 534 to extend into. Restricting rods 535 are fixedly connected to opposite sides of the lifting plate 533 to limit the hammer block 4 and reduce the possibility of displacement or falling of the hammer block 4 during the lifting process.

[0050] like Figure 3 As shown, after the hammer block 4 is hammered down for the last time, the lifting motor 52 drives the connecting block 531 to move downward along the lifting chute 513, so that the lifting plug plate 533 is aligned with the insertion hole 321, and then drives the connecting plate 532 to move relative to the connecting block 531, and inserts the plug 534 into the corresponding insertion hole 321, so that the lifting member 53 can accommodate the hammer block 4. In order to make the position transfer of the hammer block 4 more smooth, the second sleeve 312 is provided with a pushing assembly 7, which includes a pushing hydraulic cylinder 71 and a push plate 72. The pushing hydraulic cylinder 71 is fixedly connected to the sliding platform 11, and a placement slot is provided in the second sleeve 312. The push plate 72 is fixedly connected to the piston rod of the pushing hydraulic cylinder 71. When the hammer block 4 falls to hammer the pile 10, the push plate 72 is located in the placement groove, making way for the movement of the hammer block 4 and reducing the possibility of resistance to the hammer block 4. When the hammer block 4 completes the hammering, the hydraulic cylinder 71 is pushed to start driving the push plate 72 to move. The push plate 72 pushes the hammer block 4 accordingly. The push plate 72 cooperates with the insert 534 to smoothly transfer the hammer block 4 to the lifting member 53. When the lifting member 53 carries the hammer block 4 to the corresponding docking port, the connecting plate 532 extends relative to the connecting block 531, allowing the insert 534 to overlap the end of the sliding baffle 82, and then drives the lifting insert 533 to rotate downward relative to the connecting plate 532, so that the hammer block 4 enters the second sleeve 312 under the action of its own gravity.

[0051] like Figure 5 and 6 As shown, it also includes a linkage assembly 2, which includes a linkage rod 21, an auxiliary rod 23 and a linkage block 22. A dovetail groove 512 is provided on the lifting column 51 for the linkage block 22 to be placed and slided. The length direction of the dovetail groove 512 is consistent with the length direction of the lifting column 51. One end of the linkage rod 21 is hinged to the sliding baffle 82, and the other end is hinged to the linkage block 22. The auxiliary rod 23 is fixedly connected to the outer wall of the limiting sleeve 31. The linkage rod 21 is provided with an auxiliary waist hole 211 along its own length. The end of the auxiliary rod 23 away from the limiting sleeve 31 is located in the auxiliary waist hole 211 and slides. A pressure sensor 221 is fixedly connected to the side of the linkage block 22 facing the connecting block 531. The pressure sensor 221 is electrically connected to the lifting motor 52. After the pressure sensor 221 detects pressure, it transmits a signal to the lifting motor 52.

[0052] like Figure 2 and 5 As shown, when piling is in normal operation, the sliding baffle 82 slides downward, opening the first interface 83. At this time, the linkage block 22 slides upward along the dovetail groove 512 under the cooperative drive of the linkage rod 21 and the auxiliary rod 23. When the connecting block 531 carrying the hammer block 4 is lifted to abut against the linkage block 22, the pressure sensor 221 detects the abutting force of the connecting block 531 and sends a signal to the lifting motor 52. The lifting motor 52 stops running immediately after receiving the signal. At this time, the connecting block 531 carrying the hammer block 4 is located at a position corresponding to the first interface 83, facilitating the hammer block 4 to enter the second sleeve 312. When the pile 10 encounters an obstacle during penetration, the sliding baffle 82 moves upward, blocking the first interface 83 and opening the second interface 84. At this time, the linkage block 22 slides downward along the dovetail groove 512 under the cooperative drive of the linkage rod 21 and the auxiliary rod 23. When the connecting block 531 carrying the hammer block 4 is lifted to abut against the linkage block 22, the pressure sensor 221 detects the abutting force of the connecting block 531 and sends a signal to the lifting motor 52. The lifting motor 52 stops running immediately after receiving the signal. At this time, the connecting block 531 carrying the hammer block 4 is located at the position corresponding to the second docking interface 84, which is beneficial to improving the position consistency of the hammer block 4 during multiple consecutive operations.

[0053] The implementation principle of a protective hammer piling device in the embodiment of the present application is as follows:

[0054] The pile 10 is clamped by the positioning assembly 6, and then one end of the pile 10 is extended into the first sleeve 311. Then the lifting member 53 moves the hammer block 4 out of the docking outlet 3123, and the hammer block 4 is lifted and moved to the first docking port 83 through the connecting block 531, and the hammer block 4 is sent into the second sleeve 312 through the first docking port 83, so that the hammer block 4 hammers the limit bearing block 32 and the pile 10 through its own stored gravitational potential energy, so that the pile 10 penetrates into the ground.

[0055] When the pile 10 encounters an obstacle during penetration, the penetration meter 9 detects that the penetration depth does not meet the preset range, and the penetration meter 9 sends a signal to the sliding motor 81, which drives the sliding baffle 82 upward. Simultaneously, the linkage block 22 moves downward, allowing the connecting block 531 to carry the hammer block 4 and align with the second docking port 84. Since the second docking port 84 is located below the first docking port 83, the hammer block 4 has less potential energy when entering the second sleeve 312 from the second docking port 84. This reduces the hammering force of the hammer block 4 on the pile 10 after it falls, and further reduces the rebound force of the pile 10 on the hammer block 4. This protects both the pile 10 and the hammer block 4, reducing damage to the pile 10 and the hammer block 4 due to excessive rebound force.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
