Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, and in particular to a positioning device and positioning method for a pile driver used in civil engineering. Background Technology

[0002] The pile driver consists of a pile hammer, a pile frame, and auxiliary equipment. The pile hammer is attached between two parallel vertical guide rods (commonly known as a gantry) at the front of the pile frame and is lifted by a lifting hook. The pile frame is a steel structure tower with a winch at the rear for lifting the pile and pile hammer. There is a guide frame composed of two guide rods at the front of the pile frame to control the direction of pile driving, so that the pile can accurately penetrate the stratum according to the design orientation.

[0003] Existing pile drivers require manual directional stabilization during use, which increases the workload of workers to some extent. At the same time, the pile rod is prone to tilting when workers operate the pile driver, causing errors in pile driving. Therefore, we need a positioning device for pile drivers in civil engineering to solve the problems of manual directional stabilization and positional errors of the pile rod when workers operate the pile driver. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a positioning device and method for a pile driver used in civil engineering. This device enables the pile driver to move stably without the need for manual directional stabilization, avoiding shaking during movement and improving pile driving accuracy.

[0005] To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problem is as follows: the positioning device for a pile driver in civil engineering includes a support platform, side plates are respectively arranged opposite to each other on both sides of the support platform, and telescopic pressing mechanisms are slidably connected to the inner side of the side plates. The two telescopic pressing mechanisms press and position the pile driver body, and a pile rod is connected to the output end of the pile driver body. An adjustment mechanism for vertically guiding and positioning the pile rod is provided on the support platform.

[0006] The inner side of the side plate is provided with a vertical sliding groove along the vertical direction. A stop block is detachably connected to the top of the vertical sliding groove. A slider is slidably connected in the vertical sliding groove and connected to the telescopic pressing mechanism through the slider.

[0007] The telescopic clamping mechanism includes multiple horizontal telescopic rods that are slidably connected to the side plate. The telescopic ends of the multiple horizontal telescopic rods are connected to a vertical pressure plate. The upper end of the vertical pressure plate is slidably connected to the pile driver body. The two vertical pressure plates clamp the pile driver body tightly and then securely connect it.

[0008] The upper end of the vertical pressure plate is provided with a horizontal sliding groove along its length. The upper sides of the pile driver body are respectively welded with strip-shaped support feet that slide in cooperation with the horizontal sliding groove. A sealing plate is detachably connected to the end of the horizontal sliding groove. The outer end of the pile driver body is provided with a handle for easy sliding.

[0009] The inner side of the vertical pressure plate is provided with a protective pad that abuts against the body of the pile driver. The lower inner side of the vertical pressure plate is fixed with a baffle that supports the body of the pile driver. The two vertical pressure plates are detachably connected by a bolt assembly.

[0010] The output end of the pile driver body is provided with an internally threaded cylindrical section, and a sleeve is internally threaded to the internally threaded cylindrical section, and the pile rod is inserted into the sleeve for positioning.

[0011] The support platform is provided with an installation hole at a position opposite to the pile. The adjustment mechanism includes two connecting blocks welded to each other on the inner wall of the installation hole. A hydraulic cylinder I is welded and fixed on each connecting block along the radial direction of the installation hole. An arc-shaped plate is welded on the piston rod of the hydraulic cylinder I. The two arc-shaped plates are symmetrically arranged and cover the outer periphery of the pile.

[0012] The support platform is equipped with a storage box for placing installation components. The storage box includes a box body with an opening on one side, a partition fixed inside the box body, a protective plate connected to the side of the partition near the opening, and a door with a lock hinged to the opening of the box body.

[0013] The support platform includes a base plate, on which the side plates are fixed. Track structures are installed on both sides of the base plate. Connecting plates are fixed at both ends of the base plate. The lower ends of the connecting plates are connected to the support plates through multiple hydraulic cylinders II. The support plates are in contact with the ground.

[0014] A positioning method for a pile driver used in civil engineering, utilizing the aforementioned positioning device, includes the following steps:

[0015] Step 1: Position the pile driver body stably to ensure the smooth up-and-down movement of the pile driver body;

[0016] Step 2: Install the piles and guide them into position;

[0017] Step 3: Move the pile driver to the pile driving position to perform the pile driving operation.

[0018] The beneficial effects of this invention are:

[0019] 1. This invention designs a piling machine positioning device. The piling machine body can be pressed and positioned by a telescopic clamping mechanism. When the piling machine is performing piling operation, the piling machine body moves up and down along the two side plates following the telescopic clamping mechanism. Moreover, the pile rod at the output end of the piling machine body moves vertically under the action of the adjustment mechanism. The entire piling operation can make the piling machine body move stably without manual stabilization of the direction, avoiding shaking during the movement of the machine body and improving the accuracy of piling.

[0020] 2. This invention features a sleeve threadedly connected to the output end of the pile driver body, into which a pile rod is inserted and positioned. The sleeve with the appropriate hole diameter can be selected and rotated to install on the output end of the pile driver body according to the required pile rod size. This makes installation convenient and quick, avoids the need for workers to replace the pile driver multiple times, and reduces the operating cost of pile driving on the construction site to a certain extent.

[0021] 3. This invention provides mounting holes on a support platform at positions opposite to the pile rod, and fixes hydraulic cylinder I at corresponding positions on the inner wall of the mounting holes. An arc-shaped plate is connected to the piston rod of hydraulic cylinder I. The extension distance of the piston rods of the two hydraulic cylinders I can be adjusted according to the size of the pile rod, so that the two arc-shaped plates are adapted to the pile rod. This avoids the pile rod from shaking to a certain extent, and also avoids the need to replace the fixing device of the pile rod multiple times due to different pile rod sizes.

[0022] In summary, this positioning device for pile drivers in civil engineering is highly versatile and suitable for guiding and positioning piles of various sizes. It allows the pile driver to move stably without the need for manual directional stabilization, avoiding shaking during movement and improving the accuracy of pile driving.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The specific implementation scheme of this invention is as follows: Figures 1-3As shown, a positioning device for a pile driver used in civil engineering includes a support platform 1. Side plates 2 are respectively arranged opposite each other on both sides of the support platform 1. Telescopic clamping mechanisms 3 are slidably connected to the inner side of the side plates 2. The two telescopic clamping mechanisms 3 clamp and position the pile driver body 4. The output end of the pile driver body 4 is connected to a pile rod 5. An adjustment mechanism 6 is provided on the support platform 1 to vertically guide and position the pile rod 5. This allows the pile driver body 4 to move stably without manual stabilization of the direction during the entire pile driving operation, avoiding shaking during the movement of the machine body and improving the accuracy of pile driving.

[0035] Specifically, such as Figure 4 As shown, a vertical slide groove 2-1 is provided on the inner side of the side plate 2 along the vertical direction. The top cross section of the vertical slide groove 2-1 is L-shaped. After the top of the vertical slide groove 2-1 is inserted into the stop block 7, a threaded hole is provided on one side of the vertical slide groove 2-1. A threaded blind hole is provided on the stop block 7 at the position opposite to the threaded hole. The stop block 7 is fixed to the side plate 2 by screws. A slider 8 is slidably connected in the vertical slide groove 2-1 and is connected to the telescopic pressing mechanism 3 through the slider 8. The detachable installation structure of the stop block 7 prevents the slider 8 from sliding out of the vertical slide groove 2-1 when the pile driver body 4 moves, and also facilitates the installation and disassembly of the telescopic pressing mechanism 3.

[0036] Specifically, the telescopic clamping mechanism 3 includes multiple horizontal telescopic rods 3-1 that are slidably connected to the side plate 2. The telescopic ends of the multiple horizontal telescopic rods 3-1 are connected to the vertical pressure plate 3-2. After the two vertical pressure plates 3-2 are fastened together by the bolt assembly 3-6, they can hold the pile driver body 4 tightly, thus avoiding the problem of the pile driver body 4 shaking due to the gap between the pile driver body 4 and the vertical pressure plate 3-2.

[0037] To prevent the vertical pressure plate 3-2 from directly pressing and damaging the pile driver body 4, a protective pad 3-4 is installed on the inner side of the vertical pressure plate 3-2 to abut against the pile driver body 4. The protective pad 3-4 can be made of rubber and is attached to the vertical pressure plate 3-2 by adhesive. This reduces the pressure exerted by the vertical pressure plate 3-2 on the pile driver body 4 and improves the service life of the pile driver. To prevent the pile driver body 4 from detaching from the vertical pressure plate 3-2 during downward movement, a baffle 3-5 supporting the pile driver body 4 is fixed to the lower inner side of the vertical pressure plate 3-2.

[0038] The upper end of the vertical pressure plate 3-2 is slidably connected to the pile driver body 4. The specific structure is as follows: a horizontal groove 3-3 is provided at the upper end of the vertical pressure plate 3-2 along its length direction. Strip-shaped support legs 9 that slide with the horizontal groove 3-3 are welded to the upper two sides of the pile driver body 4. A sealing plate (not shown in the figure) is detachably connected to the end of the horizontal groove 3-3. A handle 10 is provided at the outer end of the pile driver body 4 for easy sliding. By holding the handle 10, the pile driver body 4 can be easily slidably installed in the horizontal groove 3-3. Fixing the sealing plate at the end of the horizontal groove 3-3 completes the initial positioning of the pile driver body 4.

[0039] Specifically, such as Figure 6 As shown, the output end of the pile driver body 4 is provided with an internal thread section 11, and a sleeve 12 is internally threaded to the internal thread section 11. A pile rod 5 is inserted and positioned inside the sleeve 12. The pile rod 5 can be stably positioned by screws installed around the sleeve 12. The sleeve 12 with the corresponding hole diameter can be selected and rotated to be installed at the output end of the pile driver body 4 according to the required size of the pile rod 5. The installation is convenient and quick, which to a certain extent avoids the need for workers to replace the pile driver multiple times, and also reduces the operating cost of pile driving on the construction site to a certain extent.

[0040] Specifically, such as Figure 5 As shown, the support platform 1 has a mounting hole 13 at a position opposite to the pile 5. The adjustment mechanism 6 includes two connecting blocks 6-1 welded to each other on the inner wall of the mounting hole 13. A hydraulic cylinder I 6-2 is welded and fixed to the connecting block 6-1 along the radial direction of the mounting hole 13. An arc plate 6-3 is welded to the piston rod of the hydraulic cylinder I 6-2. The two arc plates 6-3 are symmetrically arranged and cover the outer periphery of the pile 5. The extension distance of the piston rods of the two hydraulic cylinders I 6-2 can be adjusted according to the size of the pile 5, so that the two arc plates 6-3 are adapted to the pile 5. This avoids the pile 5 from shaking to a certain extent and avoids the need to replace the fixing device of the pile 5 multiple times due to different sizes of the pile 5.

[0041] Specifically, such as Figure 2 and Figure 3As shown, the support platform 1 is equipped with a storage box 14 for placing installation parts. The storage box 14 includes a box body 14-1 with an opening on one side. The box body 14-1 can store items that can be disassembled from the device, which is convenient for the staff to install and use. A partition 14-2 is fixed inside the box body 14-1. One or more partitions 14-2 can be provided to classify the items inside the box body 14-1, making it easier for the staff to find the corresponding items. A protective plate 14-3 is connected to the side of the partition 14-2 near the opening of the box body. The protective plate 14-3 protects the items stored on the partition 14-2, preventing the items on the surface of the partition 14-2 from falling off when the device moves and the storage box 14 shakes. A box door 14-4 with a lock is hinged to the opening of the box body 14-1, which protects the items inside the storage box 14.

[0042] Specifically, such as Figure 1 and Figure 2 As shown, the support platform 1 includes a base plate 1-1, with side plates 2 fixed on the base plate 1-1. Track structures 1-2 are installed on both sides of the base plate 1-1. Activating the track structures 1-2 moves the entire device. Simultaneously, the track structures 1-2 allow the base plate 1-1 to move on muddy surfaces, thus mitigating the problem of the base plate 1-1 being unable to move on muddy terrain. Connecting plates 1-3 are fixed to both ends of the base plate 1-1. The lower ends of the connecting plates 1-3 are connected to a support plate 1-5 via multiple hydraulic cylinders II 1-4. The support plate 1-5 is in contact with the ground. Activating the hydraulic cylinders II 1-4 keeps the base plate 1-1 in a relatively level position for pile driving, thus mitigating the problem of the pile rod 5 deviating from its original fixed position due to a large ground inclination. Furthermore, by setting up the support plates 1-5 to support the hydraulic cylinders II 1-4, the problem of the hydraulic cylinders II 1-4 tilting on soft ground is mitigated.

[0043] The method for positioning a pile driver using the designed positioning device of this invention includes the following steps:

[0044] Step 1: Stabilize the pile driver body 4 to ensure smooth vertical movement: First, the operator holds the handle 10 and slides the pile driver body 4 into the horizontal slide groove 3-3 via the strip-shaped support legs 9 on both sides, positioning the pile driver body 4 above the baffle 3-5 for protection. A sealing plate is installed at the end of the horizontal slide groove 3-3. Then, the operator activates the horizontal telescopic rods 3-1 on both sides, causing the protective pads 3-4 on the vertical pressure plates 3-2 to abut against the outer surface of the pile driver body 4. Finally, the two vertical pressure plates 3-2 are fastened together using bolt assemblies 3-6, holding the pile driver body 4 firmly in place and preventing movement between the two vertical pressure plates 3-2 to a certain extent.

[0045] Step 2: Install and guide the pile rod 5: First, according to the piling requirements, rotate the sleeve 12 of the appropriate size to the output end of the piling machine body 4, and insert and position the pile rod 5 inside the sleeve 12 so that the lower end of the pile rod 5 passes through the mounting hole 13; then, according to the diameter of the pile rod 5, start the piston rod of the hydraulic cylinder I 6-2 on both sides of the inner wall of the mounting hole 13 according to the set program to move the set distance, so that the distance between the two arc plates 6-3 is adapted to the pile rod 5, and the cavity formed by the two arc plates 6-3 is in clearance fit with the pile rod 5 to ensure a good guiding effect.

[0046] Step 3: Move the pile driver body 4 to the pile driving position for pile driving operation: Start the track structure 1-2 to move the entire device to the designated position, start the hydraulic cylinders II 1-4 at both ends of the floor to move the support plate 1-5 to contact the ground, and ensure that the base plate 1-1 is kept in a relatively horizontal state, which can further improve the accuracy and quality of pile driving.

[0047] In summary, this positioning device for pile drivers in civil engineering is highly versatile and suitable for guiding and positioning piles of various sizes. It allows the pile driver to move stably without the need for manual directional stabilization, avoiding shaking during movement and improving the accuracy of pile driving.

[0048] The above description is merely an illustration of some principles of the present invention. This specification is not intended to limit the present invention to the specific structures and applicable scope shown. Therefore, all possible modifications and equivalents that may be used fall within the scope of the patent application of this invention.
