Description

Technical Field

[0001] This invention relates to a grounding device and its construction method for a walking pile driver. Background Technology

[0002] Traditional methods for fixing the grounding angle iron in walking pile drivers involve connecting the angle iron or copper rod with an electrical wire, then manually or mechanically inserting the angle iron into the ground. This is inconvenient, and if the soil is hard, mechanical equipment is required for insertion. Manual operation alone is inefficient, results in inconsistent insertion quality, and is time-consuming.

[0003] Therefore, a grounding device and its construction method for walking pile drivers are proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technology by providing a grounding device and its construction method for walking pile drivers, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grounding device for a walking pile driver, comprising a frame, the frame being composed of two horizontally placed I-beams and a panel welded to the top surface of the I-beams, the frame being fixed to the body of the walking pile driver, and a drive motor and a plugging / unplugging mechanism being installed on the panel. The insertion and extraction mechanism includes a body, a worm gear, a connecting shaft, a worm wheel, a lead screw, a slider, and a slide bar; The output end of the drive motor is connected to the worm gear, which is located inside the machine body. The worm gear is meshed with a worm wheel for transmission, and the worm wheel is fixedly connected to the lead screw via a connecting shaft. The lead screw is threadedly connected to the slider, and the slider is fixedly connected to the slide rod to form an L-shaped structure. The slide rod is slidably connected to the machine body. The lower end of the slide rod is connected to a connecting mechanism, which is connected to a grounding angle iron; The connecting mechanism includes a square block, inside which is a plug rod. The plug rod is controlled to extend and retract by a positioning bolt and a pressing block, and is used to fix the grounding angle iron.

[0006] Preferably, the back of the machine body is provided with a bracket, which is fixedly connected to the panel.

[0007] Preferably, a fixing rod is fixed to the top surface of the machine body, a top plate is fixed to the upper end of the fixing rod, and an auxiliary shaft is fixed to the upper end of the lead screw, and the auxiliary shaft is rotatably connected to the top plate.

[0008] Preferably, the top surface of the square block of the connecting mechanism is provided with an upper baffle for limiting the grounding angle iron.

[0009] Preferably, the square block of the connecting mechanism has two insert rods inside, and the two insert rods are arranged alternately vertically.

[0010] Preferably, the inner end of the insertion rod is provided with a round head, which contacts the extrusion block.

[0011] Preferably, a return spring is provided between the round head and the inner wall of the square block cavity.

[0012] Preferably, the bottom surface of the lower baffle of the square block is provided with a cone block.

[0013] A construction method for a grounding device for a walking pile driver includes the following steps: S1: Install the grounding angle iron: Attach the inner right-angled side of the grounding angle iron to the front right-angled side of the square block of the connecting mechanism, and limit it through the upper baffle on the top surface of the square block, so that the auxiliary hole of the grounding angle iron is aligned with the insertion rod inside the square block. S2: Tighten the positioning bolt. The inner end of the positioning bolt pushes the extrusion block, which is slidably set inside the square block, to move. The extrusion block, with its outward-expanding inclined surface based on the contact point between its round head and the insertion rod, pushes the round head and the insertion rod outward, so that the insertion rod is inserted into the auxiliary hole of the grounding angle iron and the grounding angle iron is fixed. S3: Grounding plugging and unplugging: Start the drive motor, the output end of the drive motor drives the worm to rotate, and then the worm wheel drives the lead screw to rotate. The lead screw drives the slider and the slide rod to slide vertically up and down the L-shaped structure, thereby driving the grounding angle iron to be inserted or pulled out of the ground through the connection mechanism; S4: Remove the grounding angle iron: Loosen the positioning bolts. Under the elastic force of the return spring, the insertion rod and the round head retract into the square block, and the grounding angle iron can be removed.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1) This invention relates to a grounding device and its construction method for a walking pile driver. Through a linkage mechanism consisting of a positioning bolt, a compression block, a round head, and a plug rod, tightening or loosening one bolt simultaneously drives the insertion or withdrawal of two plug rods, achieving rapid locking and releasing. The plug rods are directly inserted into the auxiliary holes of the grounding angle iron, forming a reliable pin connection that effectively resists forces from all directions. The staggered arrangement of the plug rods further enhances their resistance to torsion and pull-out. The return spring ensures that the plug rods automatically and quickly return to their original position after the locking force is released.

[0015] 2) This forms a single-bolt linkage double-rod mechanism. Tightening just one bolt simultaneously drives both rods to insert or retract from the grounding angle iron auxiliary hole, eliminating the tedious process of individual operations. Locking and releasing are completed in one step. The rods are directly inserted into the holes to form a pin connection, ensuring easy alignment without additional adjustments. The staggered layout enhances stability without increasing operational steps. The return spring automatically and quickly returns to its original position after locking, requiring no manual intervention. The overall operation is extremely simple, significantly reducing assembly and disassembly time and improving construction efficiency. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, a grounding device for a walking pile driver includes a frame 1, which consists of two horizontally placed I-beams 11 and a panel 12 welded to the top surface of the I-beams 11. The frame 1 is fixed to the body of the walking pile driver. The I-beams 11 provide extremely high bending strength and load-bearing capacity to ensure that the equipment will not deform when the heavy pile driver is working. A drive motor 2 and a plug-in mechanism 3 are installed on the panel 12.

[0020] The insertion and removal mechanism 3 includes a body 31, a worm gear 39, a connecting shaft 311, a worm wheel 310, a lead screw 32, a slider 33, and a slide bar 37; a bracket 38 is provided on the back of the body 31, and the bracket 38 is fixedly connected to the panel 12.

[0021] The output end of the drive motor 2 is connected to the worm gear 39, which is located inside the machine body 31. The worm gear 39 is meshed with the worm wheel 310 for transmission. The huge reverse force of the worm wheel 310 cannot drive the worm gear 39, which allows the grounding angle iron 4 to be firmly locked in its current position after being inserted into the ground. It will not rise on its own due to the huge reaction force of the soil or the vibration of the equipment, ensuring safety. The worm wheel 310 is fixedly connected to the lead screw 32 through the connecting shaft 311. The lead screw 32 is threadedly connected to the slider 33, and the slider 33 is fixedly connected to the slide rod 37 to form an L-shaped structure. The slide rod 37 is slidably connected to the machine body 31. The top of the machine body 31... A fixing rod 34 is fixed to the surface, and a top plate 35 is fixed to the upper end of the fixing rod 34. An auxiliary shaft 36 is fixed to the upper end of the lead screw 32, and the auxiliary shaft 36 is rotatably connected to the top plate 35. The fixing rod 34 and the top plate 35 provide an auxiliary support point at the top for the high-speed rotating lead screw 32, which greatly enhances the system rigidity of the lead screw 32, prevents it from bending and shaking under pressure, thereby ensuring the vertical accuracy of the insertion and extraction action, and extending the service life of the lead screw 32 and the motor. This solves the problem of insufficient rigidity and stability of the long-stroke, high-load lead screw 32, and avoids shaking and structural deformation during equipment operation.

[0022] The lower end of the slide bar 37 is connected to a connecting mechanism 5, which is connected to the grounding angle iron 4.

[0023] The connecting mechanism 5 includes a square block 51, inside which is a rod 56. The rod 56 is controlled to extend and retract by a positioning bolt 55 and a pressing block 59, and is used to fix the grounding angle iron 4. The top surface of the square block 51 of the connecting mechanism 5 is provided with an upper baffle 52 for limiting the grounding angle iron 4. The upper baffle 52 provides quick and accurate initial positioning. The operator only needs to lean and stick the grounding angle iron 4 upwards to complete the coarse positioning without repeated adjustments, which prepares for subsequent automatic locking. This solves the problems of difficulty in drilling, need for multiple people to cooperate, or repeated adjustments during installation, resulting in low efficiency. The square block 51 of the connecting mechanism 5 has two rods 56 inside, which are staggered vertically. Two staggered insertion rods 56 form a stable two-point locking system, which can effectively resist forces from all directions on the grounding angle iron 4, especially resisting torsion and pull-out. The connection reliability is far superior to single-point fixing. The inner end of the insertion rod 56 is provided with a round head 57, which contacts the extrusion block 59. A return spring 58 is provided between the round head 57 and the inner wall of the square block 51. The bottom surface of the lower baffle 53 of the square block 51 is provided with a cone block 54. The sharp end of the cone block 54 can crush some hard soil, opening a path for the subsequent square block 51 with a larger cross section, significantly reducing the insertion resistance, so as to ensure the insertion depth of the grounding angle iron 4 and enhance the adaptability of the equipment to complex strata.

[0024] A construction method for a grounding device for a walking pile driver includes the following steps: S1: Install grounding angle iron 4: Attach the inner right-angled side of grounding angle iron 4 to the front right-angled side of square block 51 of connecting mechanism 5, and limit it by the upper baffle 52 on the top surface of square block 51, so that the auxiliary hole of grounding angle iron 4 is aligned with the insertion rod 56 inside square block 51. S2: Tighten the positioning bolt 55. The inner end of the positioning bolt 55 pushes the pressing block 59, which is slidably set inside the square block 51, to move. The pressing block 59, with its outwardly expanding inclined surface based on the contact point between its round head 57 and the insertion rod 56, pushes the round head 57 and the insertion rod 56 outward, so that the insertion rod 56 is inserted into the auxiliary hole of the grounding angle iron 4 and the grounding angle iron 4 is fixed. S3: Grounding insertion and removal: Start the drive motor 2. The output end of the drive motor 2 drives the worm 39 to rotate. Then, the worm wheel 310 drives the lead screw 32 to rotate. The lead screw 32 drives the L-shaped structure formed by the slider 33 and the slide bar 37 to slide vertically up and down, thereby driving the grounding angle iron 4 to be inserted into or pulled out of the ground through the connecting mechanism 5. S4: Remove grounding angle iron 4: Loosen the positioning bolt 55. Under the elastic force of the return spring 58, the insertion rod 56 and the round head 57 retract into the square block 51, and the grounding angle iron 4 is removed.

[0025] Working principle: A frame 1 is formed by welding a panel 12 to the top surface of two horizontally placed I-beams 11. The frame 1 is fixed to the body of the walking pile driver, serving as the foundation of the entire grounding device. A drive motor 2 and a plug-in mechanism 3 are installed on the upper surface and side of the panel 12, respectively. After starting the drive motor 2, its output end drives the worm gear 39 inside the machine body 31 fixed to the side of the panel 12 to rotate. The worm wheel 310 inside the machine body 31 rotates through the connecting shaft 311, and rotates with the worm gear 39. The upper end of the moving shaft 311 is fixed with a lead screw 32. The lead screw 32 is connected to the L-shaped structure formed by the slider 33 and the slide rod 37. The slider 33 is threadedly connected to the lead screw 32, and the slide rod 37 is slidably connected to the machine body 31. Therefore, after the lead screw 32 rotates, the entire L-shaped structure formed by the slider 33 and the slide rod 37 will slide vertically or up or down. The lower end of the slide rod 37 is connected to the grounding angle iron 4 through the connecting mechanism 5. Therefore, the grounding angle iron 4 can slide together with it to realize the insertion and removal action in the grounding process.

[0026] During the installation or replacement of the grounding angle iron 4, the main body of the connecting mechanism 5 is used to fix the square block 51 at the lower end of the slide rod 37. First, the inner right-angled side of the grounding angle iron 4 is aligned with the front right-angled side of the square block 51. The baffle 52 on the top surface of the square block 51 limits the position, so that the auxiliary hole of the grounding angle iron 4 is aligned with the insertion rod 56 inside the square block 51. Then, the positioning bolt 55 located on the back of the square block 51 is tightened. The inner end of the positioning bolt 55 pushes the pressing block 59, which is slidably set inside the square block 51, to slide towards the round head 57 at the inner end of the insertion rod 56. Using the inclined surface of the pressing block 59, which expands outward with its contact point with the round head 57 as a reference, the round head 57 and the insertion rod 56 are pushed outward. Rod 56, at this time, the return spring 58, which is fixedly connected to the round head 57 and the square block 51 at both ends respectively, is in a compressed state, and the two insert rods 56 adjacent to the right angle side of the front of the square block 51 are simultaneously inserted into the auxiliary hole of the grounding angle iron 4 to restrict the movement of the grounding angle iron 4 and achieve quick installation. At the same time, after loosening the positioning bolt 55, the restriction on the compression block 59 is released. Under the elastic force of the return spring 58, and with the two insert rods 56 set up alternately, and sufficient space can be preset inside the square block 51 for its movement, the insert rods 56 and the round head 57 will retract into the square block 51. At this time, the grounding angle iron 4 can be removed, achieving quick dismantling.

[0027] Meanwhile, a bracket 38 is added to the back of the body 31 to increase the contact area between it and the panel 12 and improve stability. A fixing rod 34 is fixed to the top surface of the body 31, and the top plate 35 is fixed to the upper end of the fixing rod 34. The upper end of the lead screw 32 is rotatably connected to the top plate 35 through the auxiliary shaft 36. With the additional support points provided by the fixing rod 34 and the top plate 35, the stability of the lead screw 32 is ensured.

[0028] Furthermore, the bottom surface of the lower baffle 53 of the square block 51 is provided with a cone 54 with its sharp end pointing downwards, so that the entire connecting mechanism 5 can be inserted into the deep underground along with the grounding angle iron 4.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
