[0037] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0038] Embodiment 1:

[0039] Reference Figure 1 and Figure 2 The present embodiment provides a pile driver, including a locomotive, a boom assembly 1, a positioning mechanism 2, a hammering mechanism 3, a clamping mechanism 4 and a swing adjustment mechanism 5; the boom assembly 1 is used to install the positioning mechanism 2, the hammering mechanism 3, the clamping mechanism 4 and the swing adjustment mechanism 5 on the working platform of the locomotive. When not working, the boom assembly 1 is parallel to the working platform as a whole, firstly to realize the supporting function, and secondly to realize the driving function when working, that is, the boom assembly 1 can be a Z-folding shape or other shapes that are convenient for telescopic changes; the hammering mechanism 3 is fixed on the boom assembly 1 along the side of the boom assembly 1 away from the working platform of the locomotive, and the hammering mechanism 3 mainly includes a support frame (not shown in the figure), a pile hammer 34, a hammer cover 35, a chain 37 and a sprocket tightening mechanism 38, wherein the support frame ( The chain 37 is arranged on the support frame (not shown in the figure) and can roll along the support frame. The sprocket tightening mechanism 38 is used to adjust the tightness of the chain 37 in real time to ensure the normal operation of the chain 37. The pile hammer 34 is arranged in the support frame (not shown in the figure) through the chain 37. The chain 37 drives the pile hammer 34 to perform a hammering-retracting cycle operation toward one end of the boom assembly 1 under power drive. The pile hammer 34 performs hammering construction along the boom assembly 1. The hammer cover 35 is sleeved on the outer periphery of the pile hammer 34 and is slidably connected to the support frame (not shown in the figure). The hammer cover 35 moves with the pile hammer 34 to limit the pile hammer 34 from moving along a predetermined track to prevent the pile hammer 34 from swinging at will.

[0040] In order to cooperate with the pile hammer 34 to drive the pile, replace manual pile support, improve the efficiency of pile driving, and avoid the occurrence of safety accidents, a dedicated clamping mechanism 4 is set on one side of the hammering mechanism 3. The clamping mechanism 4 is fixed on the arm assembly 1 and is used to clamp the pile body. When the pile hammer is driving the pile, it plays a role in replacing manual pile support and improves the accuracy of the pile position.

[0041] The swing adjustment mechanism 5 is hinged inside the boom assembly 1, and its main function is to adjust the telescopic changes of the boom assembly 1, thereby driving the hammering mechanism 3 and the clamping mechanism 4 to swing, and then the position of the hammering mechanism 3 can be flexibly adjusted according to the actual working conditions to ensure the accuracy of the piling position and angle; at the same time, the swing adjustment mechanism 5 is hinged inside the boom assembly 1, which ensures the realization of the adjustment function while also streamlining the overall structure of the equipment and saving space.

[0042] The positioning mechanism 2 is arranged at one end of the boom assembly 1, and its position is opposite to the hammering direction of the pile hammer 34. The positioning mechanism 2 is a radar antenna. The radar antenna feeds back positioning information to the on-board positioning system arranged on the locomotive, and draws a pile position map through a computer to achieve accurate positioning of the piling point. Then, a command is issued through the computer to control the swing adjustment mechanism 5 to adjust the piling position and angle of the hammering mechanism 3 through the boom assembly 1. The entire positioning process is intelligent, convenient and accurate.

[0043] Reference Figure 1 and Figure 3 In order to accurately adjust the position of the beating mechanism 3, the arm assembly 1 is provided with a first hinge shaft 11 and a second hinge shaft 12, and the first hinge shaft 11 is perpendicular to the second hinge shaft 12; the swing adjustment mechanism 5 is provided with a pitch adjustment component 51 and a yaw adjustment component 52, and the pitch adjustment component 51 drives the beating mechanism 3 and the clamping mechanism 4 to pitch and swing relative to the locomotive platform around the first hinge shaft 11 through its own telescopic movement, such as Figure 1 As shown, the beating mechanism 3 and the clamping mechanism 4 can realize a continuous large rotation of the second pitch angle b, so as to push the beating mechanism 3 to a vertical state and enter a working state. Then, if it is necessary to further tilt up, the first pitch angle a can be further tilted up under the action of the pitch adjustment component 51, wherein the first pitch angle a is a maximum of 10°, and the second pitch angle b is a maximum of 87°. In this process, fine adjustment of any angle can be performed according to the working conditions. In addition, the yaw adjustment component 52 drives the beating mechanism 3 and the clamping mechanism 4 to swing around the second hinge shaft 12 through its own telescopic movement, as shown in FIG. Figure 3As shown, the hammering mechanism 3 and the clamping mechanism 4 can realize left and right lateral swing, swinging to the left by a first swing angle c, and swinging to the right by a second swing angle d, and the maximum values ​​of the first swing angle c and the second swing angle d are both 10°; in this way, under the instruction of the positioning mechanism 2, the pitch adjustment component 51 and the swing adjustment component 52 can perform adaptive fine-tuning on the hammering mechanism 3 and the clamping mechanism 4 from four directions, for example: when the surface of the pile driving roadbed is inclined by 8°, in order to achieve pile driving in the vertical direction, the second pitch angle b can be adjusted to 82° by the pitch adjustment component 51, so that the hammering mechanism 3 can pile in the vertical direction; when it is necessary to adjust the hammering mechanism 3 to deviate 3° to the left, the first swing angle c can be adjusted to 3° by the swing adjustment component 52; and the needs of the two directions can be met at the same time to meet the needs of pile driving in different directions, thereby ensuring the accuracy of the orientation of the hammering mechanism 3 and improving the overall adaptability of the equipment for use in a variety of different working conditions.

[0044] Among them, the pitch adjustment component 51 and the yaw adjustment component 52 are both telescopic cylinders, and each component can work with a single cylinder alone or with multiple cylinders; at the same time, the telescopic cylinder can also be other structures with similar functions, which are not specifically limited here.

[0045] Reference Figure 1 and Figure 2 In order to further enhance the azimuth adjustment function of the pile driver, a slewing mechanism 6 is arranged between the boom assembly 1 and the locomotive, the slewing mechanism 6 is fixed on the locomotive, and then the boom assembly 1 is installed on the upper side of the slewing mechanism 6, the slewing mechanism 6 drives the boom assembly 1 to complete the slewing action through its own rotation, and can rotate to both sides of the locomotive respectively, and the rotation to one side of the locomotive can achieve a maximum rotation of 90°, that is, the slewing mechanism 6 can drive the hammering mechanism 3 and the clamping mechanism 4 to rotate relative to itself through the boom assembly 1; in this way, it is not only conducive to accurately adjusting the position of the hammering mechanism 3, but also when the locomotive is inconvenient to move or the construction space is limited, it can expand the construction range of the pile driver to a certain extent, and improve the overall flexibility of the equipment.

[0046] Reference Figure 1 and Figure 2In order to further expand the application scope of the pile driver, a down-the-hole drilling mechanism 7 is arranged on the arm assembly 1 in parallel with the hammer mechanism 3. The down-the-hole drilling mechanism 7 is used when the roadbed is relatively hard and it is difficult to directly pile. For example, when the roadbed contains a lot of stone, the down-the-hole drilling mechanism 7 is used to drill holes first, and then the hammer mechanism 3 is used to pile. The down-the-hole drilling mechanism 7 includes a drilling drive assembly 71 and a down-the-hole hammer 72 in sequence along the direction away from the positioning mechanism 2. The drilling drive assembly 71 and the down-the-hole hammer 72 are connected to the down-the-hole hammer through a drill rod 74. 72 is connected, and the drilling drive assembly 71 includes a rotating power part (not shown in the figure) and an impact power part (not shown in the figure). The rotating power part provides rotational power for the down-the-hole hammer 72, and the impact power part provides impact power for the down-the-hole hammer 72, so that the down-the-hole hammer 72 completes the drilling work under the combination of rotation and impact; in addition, the positioning process of the down-the-hole drilling mechanism 7 is the same as the positioning process of the hammering mechanism 3, and the switching between the down-the-hole drilling mechanism 7 and the hammering mechanism 3 is completed by the cooperation of the swing adjustment mechanism 5 and the rotary mechanism 6, which will not be repeated here.

[0047] Reference Figure 1 and Figure 2 In order to prevent the down-the-hole drilling mechanism 7 from generating dust during the drilling process, a dust collecting mechanism 73 is sleeved on the working end of the down-the-hole hammer 72. The dust collecting mechanism 73 is connected to the arm assembly 1. The dust collecting mechanism 73 can be a simple dust collecting hood or an integrated device with an additional water pump, a water tank and a nozzle. The water pump pumps water from the water tank to the dust collecting hood, and sprays it out in an atomized form through the nozzle to achieve the purpose of dust reduction, thereby improving the environmental protection of the equipment.

[0048] Reference Figure 4 and Figure 5 In order to further improve the automation and universality of the clamping mechanism 4, the clamping mechanism 4 is provided with a bracket 41, a guide block 42, a jaw plate 43, a clamping drive 44 and a swinging drive 45; one end of the bracket 41 is connected to the arm assembly 1, and the other end of the bracket 41 is connected to the guide block 42, and the guide block 42 is used to provide a holding space for the pile body; the clamping drive 44 and the swinging drive 45 are arranged on the bracket 41, and the jaw plate 43 is hinged at the upper end of the clamping drive 44, and the clamping drive 44 drives the jaw plate 43 to approach or move away from the guide block 42, so that the jaw plate 43 cooperates with the guide block 42 to clamp Or loosen the pile body; when the guide block 42 and the jaw plate 43 clamp the pile body, the pile body is parallel to the hammering mechanism 3 and is directly below the pile hammer 34; the swing driving member 45 drives to adjust the distance between the clamping mechanism 4 and the hammering mechanism 3. When the clamping mechanism 4 is away from the hammering mechanism 3, the guide block 42 and the jaw plate 43 are separated, and the pile body is loaded therein, and the guide block 42 and the jaw plate 43 are clamped. Then the swing driving member 45 drives the clamping mechanism 4 to be directly below the pile hammer 34, which is convenient for subsequent piling work, that is, the automatic return of the pile body is realized. At the same time, the jaw plate 43 cooperates with the guide block 42 to be suitable for different types of piles.

[0049] Reference Figure 6 In order to further improve the accuracy of the position of the pile body in the hammering mechanism 3, a limiter 31 is set at the end of the hammering mechanism 3. The limiter 31 is used to further limit the position of the pile body. The limiter 31 includes a limit bracket 311, an adjusting bolt assembly 32 and a guide roller assembly 33. The limit bracket 311 is an arc-shaped structure. Both ends of the limit bracket 311 are connected to the supporting frame (not shown in the figure) of the hammering mechanism 3. The hollow area inside the arc-shaped structure is for the pile body to pass through; the adjusting bolt assembly 32 is composed of a plurality of bolt structures, and the plurality of bolt structures are distributed on the periphery of the limit bracket 311 and are all facing the limit bracket 311. Internal hollow area; the guide roller assembly 33 is composed of multiple guide rollers, and the multiple guide rollers are distributed inside the arc structure along the circumference of the limit bracket 311, and the multiple guide rollers are slidably arranged on the guide roller support frame 39, and the roller body wall of the guide roller faces the internal hollow area of ​​the limit bracket 311, that is, it is used to contact the pile body. The setting of multiple guide rollers can achieve the clamping of the pile body while facilitating the falling of the pile body, killing two birds with one stone; at the same time, the bolt assembly 32 is adjusted to movably resist the guide roller to adjust the reciprocating movement of the guide roller on the guide roller support frame 39, thereby adjusting the caliber of the limiter 31 to adapt to different types of pile bodies.

[0050] Reference Figure 7 In order to further enhance the comprehensive functions of the pile driver, a pile pulling mechanism 8 is further provided on the side wall of the hammer cover 35. When pile pulling is required, the pile pulling mechanism 8 is used to perform the pile pulling operation. The pile pulling mechanism 8 comprises a pile pulling bracket 81, a lever 82 and a pulling tool 83. One end of the pile pulling bracket 81 is connected to the side wall of the hammer cover 35, and the other end is hinged to the middle part of the lever 82. One end of the lever 82 is detachably connected to the hammering surface of the pile hammer 34, and the other end is hinged to the pulling tool 83. The pulling tool 83 is used to fix the pile body to be pulled out. When pile pulling is required, one end of the lever 82 is connected to the hammering surface of the pile hammer 34. When the pile hammer 34 performs the pile driving operation, the pulling tool 83 at the other end of the lever 82 is driven, that is, the pile pulling is realized by the principle of the lever 82. When pile pulling is not required, the pile pulling mechanism 8 is hung up by the chain 84 without affecting the pile driving process. The structure is simple, occupies little space, has multiple uses, and is easy to operate.

[0051] Reference Figure 7 In order to effectively reduce construction noise and avoid environmental noise pollution, the pile hammer 34 adopts a hydraulic silent hammer. A sound insulation cover 36 is arranged near the hammering surface of the hydraulic silent hammer. The sound insulation cover 36 is connected to one end of the hammer cover 35. The sound insulation cover 36 is composed of a perforated plate and glass wool, which can effectively reduce the noise by 10-20db. At the same time, a layer of sound insulation cotton can be covered on the pile hammer 34 to further reduce the construction noise.

[0052] The specific operation process of the pile driver in this embodiment is as follows: first, the pile driver is transported to the working position by a locomotive, and then the pile driving position is determined by the positioning mechanism 2, and at the same time, the swing adjustment mechanism 5 and the slewing mechanism 6 are adjusted according to the pile driving position indication, and the swing adjustment mechanism 5 and the slewing mechanism 6 adjust the hammering mechanism 3 and the clamping mechanism 4 to the accurate working position and pitch and yaw angles through the boom assembly 1, and the clamping mechanism 4 grabs the pile body and returns it to its position, and then the aperture is adjusted to adapt to different types of pile bodies through the limiter 31. After double positioning, the hammering mechanism 3 starts to implement pile driving; if drilling is required, the down-the-hole drilling mechanism 7 is called, and the above operation is repeated.
