Description

Technical Field

[0001] The present invention belongs to the technical field of pile drivers, and specifically relates to a foundation pile driver adaptable to complex terrains. Background Art

[0002] A foundation pile driver is a mechanical device used for driving piles into the ground. Pile driving is a common foundation treatment method in construction engineering. The purpose is to drive piles into the ground to improve the bearing capacity of the foundation or prevent problems such as settlement and displacement of buildings.

[0003] For example, the utility model with the publication number CN219992446U discloses a walking mechanism of a pile driver, including an installation base. A moving mechanism is arranged at the bottom of the installation base. The moving mechanism includes a moving base, an engine, driving wheels, supporting wheels, and a crawler. A supporting mechanism is arranged on the side wall of the installation base. A pile driving mechanism is arranged in the center of the top of the installation base, and a control mechanism is arranged at the edge of the top of the installation base; by providing a moving mechanism, the engine drives the driving wheels to rotate, the driving wheels drive the crawler to rotate, and the crawler drives the pile driver to move. Multiple supporting wheels support the crawler. Using the crawler as the driving component of the pile driver enables the pile driver to be used on complex terrains, increases the passability of the pile driver, and improves the compatibility of the pile driver in use. A supporting mechanism is provided for the horizontal support operation of the pile driver to prevent the pile driver from tilting during pile driving operations, improving the quality and efficiency of pile driving; When the above device is in use, the height is measured by a level and multiple support legs are driven to move downward synchronously, thereby achieving the horizontal support effect of the pile driver. However, when the pile driver works on complex terrains, although the device can measure the height through the level and drive the support legs to move downward, for some extremely uneven situations, such as large pits, large protrusions, or irregular slopes, it may be difficult to quickly and accurately adjust to a completely horizontal state, thus affecting the stability and working accuracy of the pile driver. At the same time, the level may malfunction during use, which may cause the entire horizontal support adjustment system to stop working or become chaotic, and then lead to the pile driver having to suspend operations for repair or debugging, affecting the construction progress and increasing the construction cost. Therefore, a foundation pile driver adaptable to complex terrains is proposed to solve the problems raised in the background art. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides a foundation pile driver adaptable to complex terrains, which has the advantage of conveniently fixing the support legs at the four corners of the pile driver according to the height of the complex terrain.

The pile driver further includes: A cloth crawler is installed on both sides of the base to increase the stability and adaptability of the pile driver on complex terrains; Tilting cylinders are symmetrically arranged on both sides of the top of the base, and a pile driving assembly is hinged to the top ends of the tilting cylinders. A limiting block is fixedly connected to one side of the pile driving assembly; Positioning assemblies, the number of which is four, are respectively fixedly connected to the four corners of the base; An adjusting assembly is movably connected inside the base; Among them, the positioning assembly includes a support block. A support leg is movably connected inside the support block. A plurality of anchor nails are fixedly connected to the bottom of the support leg. A wire drum is movably connected to the top of the support block. A steel wire rope is wound and connected to the outside of the wire drum; A spring is fixedly connected to the top of the support leg. A threaded rod is threadedly connected to one side of the support leg. One end of the threaded rod is movably clamped with an inclined block. Tooth blocks are movably connected to both sides of the inclined block inside the support leg. Tooth plates are fixedly connected to both sides of the inner wall of the support block.

[0006] Preferably, the adjusting assembly includes a limiting plate. A second inclined groove and a first inclined groove are respectively formed on the upper and lower sides of the surface of the limiting plate. A support plate is movably connected inside the base. A placement box is arranged at the top of the end of the support plate away from the pile driving assembly.

[0007] Preferably, two pulleys are installed on both sides of the support plate. A chute matched with the pulley is arranged on the inner wall of the base. The chute provides a clear moving track for the pulley, so that the pulley can only drive the support plate to move along a predetermined direction.

[0008] Preferably, the first inclined groove and the second inclined groove face in opposite directions. A connecting column movably clamped inside the first inclined groove is arranged in the middle of the support plate. A round rod movably clamped inside the second inclined groove is arranged at the end of the limiting block away from the pile driving assembly.

[0009] Preferably, a counterweight block is placed inside the placement box. A first connecting rod is hinged to the bottom of the end of the support plate close to the placement box. A second connecting rod is hinged to the end of the base close to the first connecting rod. A triangular structure is formed among the first connecting rod, the support plate and the side wall of the base.

[0010] Preferably, a straight groove is formed on the surface of the second connecting rod. The bottom end of the first connecting rod is movably clamped inside the straight groove of the second connecting rod; A square groove for limiting the limiting plate in the vertical direction is formed on the inner wall of the base. A control room is arranged in the middle of the top end of the base.

[0011] Preferably, the bottom end of the support leg penetrates through the outer wall of the support block and extends to the outside of the support block. The bottom end of the steel wire rope is fixedly connected to the top end of the support leg. A round hole for reducing the friction between the steel wire rope and the inner wall of the support block is formed at the top end of the support block.

[0012] Preferably, a handle is fixedly connected to one end of the wire drum. The top end of the spring is fixedly connected to the inner wall of the support block. The tooth block is engaged with the tooth plate in the initial state.

[0013] Preferably, the tooth block penetrates through the outer wall of the support leg and extends to the outside of the support leg. A elastic sheet is fixedly connected between the two tooth blocks. One end of the tooth block close to the inclined block is beveled.

[0014] Preferably, both ends of the inclined block are beveled. The two ends of the inclined block are respectively abutted against the beveled surfaces of the two tooth blocks. A vertical groove matching with the threaded rod is formed on one side of the outer wall of the support block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation between structures such as anchor nails, springs, tooth blocks and tooth plates, the present invention facilitates the fixing of the support legs at the four corners of the pile driver according to the height of complex terrains. When the engagement between the tooth block and the tooth plate is released, the support leg will drive the anchor nail to quickly move downward under the action of the spring force, so that the anchor nail generates a large impact force on the soil and is stuck into the soil. Subsequently, by rotating the threaded rod, the inclined block is made to squeeze the two tooth blocks to move in opposite directions and be stuck into the inside of the tooth plate, so as to fix the position of the support leg after moving downward. Subsequently, the same steps are implemented for the other three positioning components in turn, so that the other three support legs are stuck into the soil at different heights, thereby realizing the support effect of the pile driver on complex terrains.

[0016] Through the cooperation between structures such as the limiting block and the adjusting component, the present invention facilitates maintaining the gravity balance during the operation of the pile driver. When the pile driving component moves, it will drive the limiting block to move in the same direction, so that the round rod at one end of the limiting block slides inside the second inclined groove, thereby driving the limiting plate to move upward. Since the first inclined groove and the second inclined groove face in opposite directions, when the limiting plate moves upward, it will drive the connecting column of the support plate to slide inside the first inclined groove, thereby driving the placement box to move through the support plate, so that the pile driving component and the counterweight always move in opposite or the same direction, so that the overall center of gravity of the pile driver always remains within a relatively stable range, thereby improving the stability of the pile driver during operation on complex terrains.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 7 shown, the present invention provides a foundation pile driver adaptable to complex terrains, including a base 1, and further including: Cloth crawler 2, and the cloth crawler 2 is installed on both sides of the base 1; Tilting cylinders 4, the tilting cylinders 4 are symmetrically arranged on both sides of the top of the base 1, and the top ends of the tilting cylinders 4 are hinged with a pile driving component 3, and a limit block 7 is fixedly connected to one side of the pile driving component 3; Positioning components 6, the number of the positioning components 6 is four, and they are respectively fixedly connected to the four corners of the base 1; Adjusting component 8, and the adjusting component 8 is movably connected to the inside of the base 1; Among them, the positioning component 6 includes a support block 61, a support leg 62 is movably connected inside the support block 61, a plurality of anchor bolts 63 are fixedly connected to the bottom of the support leg 62, a wire reel 64 is movably connected to the top of the support block 61, and a steel wire rope 66 is wound and connected to the outside of the wire reel 64; A spring 67 is fixedly connected to the top of the support leg 62. One side of the support leg 62 is threadedly connected with a threaded rod 68. One end of the threaded rod 68 is movably clamped with an inclined block 69. Inside the support leg 62, there are tooth blocks 610 movably connected on both sides of the inclined block 69. On both sides of the inner wall of the support block 61, there are fixedly connected tooth plates 611.

[0021] Adopting the above scheme: Through the design of the cloth crawler 2, the stability and adaptability of the pile driver on complex terrains are increased. Since the pile driver itself is relatively heavy, therefore, on some complex terrains with low bearing capacities such as soft soil foundations and sandy lands, if ordinary tires or other support methods are used, the concentrated pressure can easily cause the pile driver to sink into the ground. However, through the design of the cloth crawler 2, the weight of the pile driver can be evenly distributed over a larger ground area, thereby reducing the pressure on the ground, and then ensuring the normal movement and operation of the equipment on complex terrains. The positioning components 6 are arranged at the four corners of the base 1. Its function is that when the pile driver works on complex terrains, the soil surface is mostly uneven. Therefore, the horizontal heights of the pile driver in the front, back, left, and right directions may not be the same. At this time, by arranging the positioning components 6 at the four corners of the base 1, support can be provided for the pile driver in four directions, forming a stable quadrilateral support structure, and then effectively supporting the pile driver on complex terrains.

[0022] As Figure 1 and Figure 7 As shown, the adjusting component 8 includes a limiting plate 81. Second inclined grooves 83 and first inclined grooves 82 are respectively formed on the upper and lower sides of the surface of the limiting plate 81. Inside the base 1, there is a support plate 84 movably connected. At the top of the end of the support plate 84 far from the pile driving component 3, there is a placement box 85. On both sides of the support plate 84, two pulleys 86 are installed. On the inner wall of the base 1, there are chutes that cooperate with the pulleys 86. The end of the support plate 84 far from the pulleys 86 penetrates the outer wall of the base 1 and extends to the outside of the base 1. The first inclined groove 82 and the second inclined groove 83 face in opposite directions. A connecting column that is movably clamped inside the first inclined groove 82 is arranged in the middle of the support plate 84. At the end of the limiting block 7 far from the pile driving component 3, there is a round rod that is movably clamped inside the second inclined groove 83.

[0023] Adopting the above scheme: Through the design of the pulleys 86 and the chutes inside the base 1, its function is that the chutes provide a clear moving track for the pulleys 86, so that the pulleys 86 can only drive the support plate 84 to move along a predetermined direction. At the same time, the rolling of the pulleys 86 in the chutes greatly reduces the frictional force compared to the direct sliding of the support plate 84 on the inner wall of the base 1. This makes it easier for the support plate 84 to drive the counterweight 89 to move, can quickly respond to operation instructions, thereby reducing power loss, and then quickly and efficiently completing the position adjustment of the counterweight 89, thus improving work efficiency.

[0024] As Figure 1 and Figure 7 shown, a counterweight 89 is placed inside the placement box 85. One end of the bottom of the support plate 84 close to the placement box 85 is hinged with a first connecting rod 87. One end of the base 1 close to the first connecting rod 87 is hinged with a second connecting rod 88. A straight groove is formed on the surface of the second connecting rod 88. The bottom end of the first connecting rod 87 is movably clamped inside the straight groove of the second connecting rod 88. A square groove for vertically limiting the limiting plate 81 is formed on the inner wall of the base 1. A control room 5 is arranged in the middle of the top end of the base 1.

[0025] Adopting the above solution: Through the design of the first connecting rod 87 and the second connecting rod 88, its function is that when the support plate 84 moves away from the pile driving assembly 3, at this time, the bottom end of the first connecting rod 87 will slide inside the straight groove of the second connecting rod 88, so as to adjust the length between the first connecting rod 87 and the second connecting rod 88 after the support plate 84 moves. After the support plate 84 slides, at this time, a triangular structure will be formed between the first connecting rod 87, the support plate 84 and the side wall of the base 1. This triangular structure can effectively support one end of the support plate 84 close to the counterweight 89. At the same time, the triangular structure increases the overall support surface and stability, and thus can effectively improve the anti-overturning ability of the support plate 84 when moving.

[0026] As Figures 2 to 6 shown, the bottom end of the support leg 62 penetrates through the outer wall of the support block 61 and extends to the outside of the support block 61. The bottom end of the steel wire rope 66 is fixedly connected to the top end of the support leg 62. A round hole is formed in the middle of the top end of the support block 61. One end of the wire reel 64 is fixedly connected with a handle 65. The top end of the spring 67 is fixedly connected to the inner wall of the support block 61. The tooth block 610 is initially clamped with the tooth plate 611. The tooth block 610 penetrates through the outer wall of the support leg 62 and extends to the outside of the support leg 62. An elastic sheet 612 is fixedly connected between the two tooth blocks 610. One end of the tooth block 610 close to the inclined block 69 is beveled. Both ends of the inclined block 69 are beveled. Both ends of the inclined block 69 are respectively abutted against the beveled surfaces of the two tooth blocks 610. A vertical groove matched with the threaded rod 68 is formed on one side of the outer wall of the support block 61.

[0027] Adopting the above solution: Through the design of the handle 65, its function is that after the pile driver operation is completed, at this time, the operator rotates the handle 65, thereby driving the wire reel 64 to rotate, and then winding the steel wire rope 66. While the steel wire rope 66 is being wound, it drives the support leg 62 and the anchor 63 to move upward, so as to reset the support leg 62. After the support leg 62 is reset, the operator rotates the threaded rod 68 again to fix the support leg 62, so as to facilitate the reset of the support leg 62 after use for the next use.

[0028] It should be noted here that: if the ground soil texture is hard and dense, such as rock or compact clay, a single impact of the support leg 62 is difficult to drive the anchor 63 into the ground in place, and multiple operations are often required. At this time, the wire reel 64 can also be rotated to drive the wire rope 66 to take up the line, so that the support leg 62 compresses the spring 67. When the operator stops rotating the wire reel 64, the support leg 62 will drive the anchor 63 to continue to impact the ground under the action of the elastic force of the spring 67. Repeating this operation will gradually increase the penetration depth and thus improve the anchoring effect.

[0029] The working principle and usage process of the present invention: When the device travels to the predetermined position, due to the uneven ground, it is necessary to fix the four support legs 62 at different heights in sequence. At this time, the operator rotates the threaded rod 68, and through the threaded connection between the threaded rod 68 and the support leg 62, drives the inclined block 69 to move away from the tooth block 610. After the inclined block 69 moves, it will release the abutment with the inclined surfaces of the two tooth blocks 610, and then the two tooth blocks 610 will move towards each other under the action of the tensile force of the elastic piece 612, and thus contract into the interior of the support leg 62, and then release the engagement with the tooth plate 611. Subsequently, the support leg 62 quickly moves downward under the action of the elastic force of the spring 67, generating a strong impact force in a short time and transmitting the impact force to the anchor 63, thereby greatly increasing the pressure of the anchor 63 on the ground. When the pressure exceeds the compressive strength of the ground soil, several anchors 63 are inserted into the soil; When the anchor 63 is inserted into the soil and tightly engages and anchors with the soil, at this time, the operator reversely rotates the threaded rod 68, and through the threaded rod 68, drives the two ends of the inclined block 69 to abut against the inclined surfaces of the two tooth blocks 610 again, so that the two tooth blocks 610 move in opposite directions under extrusion and re-engage into the interior of the tooth plate 611, thereby fixing the position of the support leg 62 after it has moved downward, and thus improving the fixing effect between the anchor 63 and the soil, preventing the anchor 63 from shifting during the operation of the device. Subsequently, the operator, according to the above operation, sequentially inserts the anchors 63 at the remaining three corners into the soil respectively and fixes the support legs 62 at different heights, so as to facilitate the effective fixation of the four corners of the pile driver, and thus improve the safety and efficiency of the pile driver working on complex terrains; Subsequently, the operator controls the device in the control room 5, so that the pile driving assembly 3 moves away from the control room 5 until it moves to a predetermined position for pile driving. When the pile driving assembly 3 moves, it will also drive the limit block 7 at its top to move together, so that the round rod at the top of the limit block 7 slides inside the second inclined groove 83. Since the second inclined groove 83 is limited in the vertical direction by the square groove, when the limit block 7 moves towards the pile driving assembly 3, it will drive the limit plate 81 to move upward along the track of the second inclined groove 83. During the upward movement of the limit plate 81, the connecting columns on both sides of the support plate 84 move outward along the track of the first inclined groove 82 towards the outside of the base 1, so as to drive the placement box 85 and the counterweight 89 inside it to move together through the support plate 84, thereby realizing the synchronous and opposite movement of the pile driving assembly 3 and the counterweight 89. Thus, through the movement of the counterweight 89, the change in the center of gravity caused by the movement of the pile driving assembly 3 is balanced, so that the overall center of gravity of the pile driver always remains within a relatively stable range, thereby preventing the possibility of the pile driver tipping or tilting due to center of gravity imbalance under complex geological conditions, and thus improving the stability of the device during operation on complex terrains.
