[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] As attached Figure 1-4 The described pile driver chassis with high efficiency in mobilization and assembly and its mobilization and assembly method include a chassis frame 1, on which a walking mechanism 2 and a pile driver connection mechanism 3 are arranged; wherein the chassis frame 1 is preferably a symmetrical structure, the walking mechanism uses a walking wheel with a self-contained driving module, and a plurality of walking wheels are symmetrically arranged about the chassis frame, preferably four, respectively arranged at the four corners of the chassis frame, and the driving modules of the plurality of walking wheels are cooperatively controlled by a control system to realize the basic functions of the chassis frame such as movement and steering. The pile driver connection mechanism is mainly used to realize the rapid connection between the chassis and the pile driver body.

[0029] The walking mechanism 2 is movably connected to the chassis frame 1 through an adjustment mechanism 4, which is used to switch the walking form and the supporting form of the walking mechanism 2; wherein, in the walking form, multiple walking wheels are in an upright state and in the same direction, realizing the basic forward and backward movement function, and in the supporting form, the walking wheels are in contact with the ground at an arbitrary angle relative to the chassis, so that the side of the walking wheels can bear the main weight of the chassis and the pile driver body. The walking wheels in the relatively upright state have a larger supporting area, can bear a larger weight, and provide a more stable support.

[0030] The reserved connection structure of the pile driver connection mechanism 3 and the pile driver body 5 is relatively plugged in and limited and pressed and fixed; the plug-in connection has fast positioning and efficient assembly, and the connection strength of the connection is improved with pressurized tightening to ensure the stable connection between the pile driver body and the pile driver chassis, and ensure the stability of the body during operation.

[0031] The pile driver connection mechanism 3 is provided with a plug-in positioning structure and a pressurized fastening structure, and the chassis frame 1 is provided with a power device, and the power device drives the plug-in positioning structure to be plugged and fitted with the reserved connection structure, and the power device is connected to the pressurized fastening structure and the adjustment mechanism 4 through a transmission structure 6; the assembly action, the pressurized fastening action and the support posture adjustment action are linked together through a set of transmission structures, and are driven by only one set of power devices, which can reduce output energy consumption, ensure that multiple actions are carried out synchronously to improve efficiency, and ensure the coordination of multiple actions without mutual interference, so that each action process is very smooth, ensuring efficiency while ensuring stability and safety.

[0032] The transmission structure 6 includes an assembly transmission structure 61 and an adjustment transmission structure 62. The deeper the insertion depth of the plug-in positioning structure driven by the power device, the greater the clamping force applied by the assembly transmission structure 61 to drive the pressurized fastening structure to move, and the greater the degree to which the adjustment transmission structure 62 drives the adjustment mechanism 4 to adjust the walking mechanism 2 to a fully horizontal support state; in the fully horizontal support state, the walking mechanism switches to the extreme position state of the support form, that is, corresponding to the support form supported on the horizontal ground. At this time, the insertion depth and the degree of clamping are the largest. Most common scenarios are carried out on the horizontal ground, thereby ensuring that the theoretical maximum connection strength can be effectively guaranteed in most operating scenarios. In other support forms, the walking wheels are in an inclined state but still fully fit with the ground. For example, when working in a small-sized pit, the walking wheels and the surrounding annular pit wall supports are relatively weak in insertion depth and compression relative to horizontal supports, but the connection strength can meet the operating requirements. In addition, due to the supporting effect of the annular wall and the horizontal component of the supporting force, the connection strength between the chassis and the pile driver is further strengthened. Therefore, while achieving coordinated and synchronous adjustment and rapid positioning, the support strength and connection strength in any support angle scenario are guaranteed, that is, the stability of the body during operation is guaranteed, ensuring operation safety.

[0033] The multiple walking mechanisms 2 are adjusted synchronously. During the adjustment process, the positions and postures of the multiple walking mechanisms 2 are always symmetrical relative to the chassis frame 1, and the height of the chassis frame 1 from the ground remains unchanged. Since the height of the center of gravity of the walking wheel changes during the flipping from the upright state to the horizontal state, it will affect the height of the pile driver chassis. If the chassis and the pile driver body are plugged in horizontally, it may cause mutual interference. In addition, during the assembly process, the change in the height of the chassis or the tilting will affect the assembly effect and the overall stability and safety of the pile driver after assembly. This solution ensures the synchronous adjustment of multiple walking mechanisms 2 through the design of the adjustment mechanism 4 and the adjustment transmission structure 62, and the adjustment degree remains consistent. At the same time, it will not affect the height of the pile driver chassis, which not only ensures the stability and smoothness during the assembly process, but also ensures the stability during the operation after the assembly is completed.

[0034] The power device drives the two plug-in positioning structures to approach each other synchronously, so as to achieve the clamping effect on the pile driver body from both sides. The plug-in positioning structure includes a movable frame 31 connected to the power device, and the movable frame 31 slides horizontally toward or away from the pile driver body 5. A plug-in plate 32 is provided on the side of the movable frame 31 close to the pile driver body 5, and the plug-in plate 32 is inserted and matched with the inner wall slot of the pile driver body 5. Among them, the plug-in plate can adopt a pin structure, and the corresponding reserved plug-in structure adopts a socket structure. The preferred embodiment of this scheme is a plug-in plate structure, which has a larger area of ​​lateral pressure, a better fastening effect, and a stronger connection strength.

[0035] Each of the plug-in positioning structures is provided with two plug-in plates 32, and the movable frame 31 is fixedly provided with a transverse guide rod 33, and a transfer bracket 34 is slidably sleeved on the transverse guide rod 33. The transfer bracket 34 is fixedly connected to the plug-in plate 32 on one side close to the pile driver body 5, and the transfer bracket 34 is used for transmission connection with the assembly transmission structure 61, and the assembly transmission structure 61 pushes the two plug-in plates 32 relatively far apart following the insertion action of the plug-in plate 32. Among them, the plug-in plate is relatively perpendicular to the movable frame, and the relatively close external clamping of the movable frames on both sides, combined with the relatively distant internal non-clamping of the two plug-in plates in the orthogonal direction, can realize the complete limit fixation of the chassis and the pile driver body in the horizontal plane, and the limit of the plug-in plate by the slot realizes the complete limit in the vertical direction, thereby realizing the complete limit fixation between the chassis and the pile driver body as a whole.

[0036] Among them, the movable frame is parallel to the slot insertion port and symmetrical with respect to the chassis frame, and the plug board and the slot are symmetrical with respect to the chassis frame. The power device pushes the movable frame to move horizontally close to the slot port, so that the plug board is inserted into the slot accordingly. Two guide holes are symmetrically opened on the movable frame, and the bearing in the guide hole is connected to a driving nut. The nut is determined to cooperate with the threaded guide rod thread. By rotating the driving nut, the nut pushes the movable frame to move along the direction of the threaded guide rod. The threaded guide rod is laterally fixed on the chassis frame. The parallel arrangement of the two threaded guide rods can enhance the moving stability of the movable frame. Preferably, the surfaces of the two driving nuts are processed with gear surfaces, and both are engaged with the driving gear. The driving gear is driven to rotate by the motor, so that the two driving nuts on the movable frame are pushed synchronously, thereby ensuring that the movable frame is always close to the slot port in a state parallel to the slot port, thereby ensuring the accurate insertion of the plug board.

[0037] By inserting two plug plates on the inner side of the pile driver body frame and driving the two plug plates relatively away from each other, a horizontal pressure is generated from the inside to the outside, and a horizontal inward limiting force is generated through the pile driver frame structure, thereby achieving a fastening connection between the chassis and the pile driver body. This plug-in fastening connection method has a simple structure, is easy to position and insert, and is conducive to improving assembly efficiency.

[0038] Preferably, as attached Figure 2As shown in, the assembly transmission structure 61 includes a bidirectional screw 611, and the bidirectional screw 611 is provided with two equal-length relatively opposite threaded surfaces, and the two ends of the bidirectional screw 611 are respectively connected to the movable frame 31 through bearings, and the middle part of the bidirectional screw 611 is fixedly sleeved with a first transmission gear 612, and the first transmission gear 612 is meshed with a first rack 613, and the first rack 613 is fixedly connected to the chassis frame 1, and the first rack 613 is horizontally arranged; the adapter bracket 34 is provided with a screw hole adapted to the bidirectional screw 611, and the two adapter brackets 34 are respectively matched with the threaded surfaces of different rotation directions on both sides of the first transmission gear 612. When the movable frame moves in close contact with the chassis frame and approaches the pile driver body, it will drive the horizontal movement of the bidirectional screw. Due to the meshing and limiting effect of the gear rack, the first transmission gear 612 will rotate, thereby driving the bidirectional screw to rotate, so that the adapter bracket will move along the axial direction of the screw. Since the threads on both sides rotate in opposite directions, the two adapter brackets will move away from each other synchronously, thereby increasing the pressure of the plug plate on the side wall of the slot.

[0039] An elastic seal is provided between the insert plate 32 and the slot surface to which it is pressed and fitted, preferably a rubber pad, which can play a buffering role and provide space for the lateral movement of the insert plate. A plurality of suction cup cavities are provided on the fitting surface of the elastic seal and the slot. When the insert plate compresses the rubber pad, the air in the suction cup cavity is squeezed out, so that there is not only a pressing force but also a suction force between the insert plate and the slot, making the connection between the two more reliable; preferably, a plurality of pressure valves are provided on the groove surface of the elastic seal corresponding to the plurality of suction cup cavities, which are used to discharge the air in the suction cup cavity when the pressure on the elastic seal increases, and to fill the suction cup cavity with air when the pressure on the elastic seal decreases. The pressure valve includes a channel connecting the suction cup cavity and the outside atmosphere after being pressed and fitted, and a valve core is connected to the channel through an elastic reset member. When the insert plate compresses the rubber pad, the air pressure in the suction cup cavity increases, thereby pushing open the valve core, so that excess air is discharged from the channel. After the compression stops and the air pressure on both sides of the valve core is balanced, the valve core is reset under the action of the reset elastic member. In the normal connection state, the plug plate is pressed against the inner wall of the slot, and the external atmospheric pressure presses the slot wall and the plug plate against each other. The two-way force makes the connection more reliable. When the plug plate tends to move away from the slot and fit the slot wall due to some faults, affecting the connection strength, the suction cup cavity tends to become larger, making the internal air pressure smaller. Under the action of atmospheric pressure, the valve core is pressed, and air cannot enter, so the plug plate and the slot are firmly sucked together to avoid loose connection in the working state. The valve core can also be actively driven to open. When it is necessary to separate the pile driver chassis from the pile driver body, the valve core is actively opened to allow air to enter, which plays a certain role in promoting the separation of the plug plate and the slot. At the same time, in the working state, if the power device is started by mistake, the chassis is separated from the pile driver body. At this time, since the valve core is not actively opened, there is a relative adsorption effect between the plug plate and the slot. Before the driving force of the plug plate retreats completely overcomes the tensile stress of the rubber pad, the chassis will not be separated from the pile driver, thereby providing a buffer time for rescue of erroneous operation. During this period of time, safety accidents can be avoided by issuing alarms or emergency measures.

[0040] The walking mechanism 2 is movably connected to the chassis frame 1 through the swing arm 40, and the adjusting mechanism 4 adjusts the angle between the outer end surface of the walking wheel and the ground, and adaptively adjusts the height of the swing arm 40 away from the chassis frame 1. That is, the angle adjustment of the walking wheel and the angle adjustment of the swing arm are coordinated, thereby achieving a constant height between the chassis frame and the ground.

[0041] Preferably, as attached Figure 3As shown in, the adjustment mechanism 4 includes a sleeve 41, and the sleeve 41 is rotatably sleeved on the upper end of the vertical shaft 11, and the vertical shaft 11 is fixedly set on the chassis frame 1; a first hinge shaft is symmetrically arranged on the outer side of the tube wall of the sleeve 41, and the swing arm 40 swings around the first hinge shaft; the hinge hole of the swing arm 40 away from the sleeve 41 is matched with the second hinge shaft 21 on the walking mechanism 2; a short shaft 42 is fixedly connected to the outer side of the swing arm 40, and the short shaft 42 is coaxially arranged with the first hinge shaft, and the short shaft 42 is connected to the second hinge shaft 21 through a sprocket structure; a bevel gear plate 43 is fixedly sleeved on the bottom end of the vertical shaft 11, and a bevel gear ring 44 meshing with the bevel gear plate 43 is fixedly sleeved on the short shaft 42. The rotation of the sleeve can drive the swing arm to swing in the horizontal plane, thereby driving the rolling of the helical gear ring 44 relative to the helical gear disc 43, and then driving the rotation of the short shaft 42. The rotation of the short shaft drives the swing arm to swing in the vertical direction, and at the same time drives the rotation of the sprocket structure pulley, thereby driving the angle adjustment of the running wheel through the sprocket structure transmission. When the swing arm swings from the left and right sides of the chassis frame to the front and back sides, the running wheel just flips from the upright form to the horizontal support form, and the inclined support form in the middle transition, and multiple swing arms present a divergent angle position, which is very consistent with the support requirements of the pit working environment. Here, left and right, front and back are relative to the movement direction of the chassis frame in the walking form, and the forward and backward directions are front and back, and the two sides are left and right. When the running wheel is adjusted to a certain tilt angle state, the horizontal orientation of the chassis frame can also be changed by the running wheel, that is, the steering function of the chassis frame is realized, and a certain position adjustment function is activated during assembly and positioning.

[0042] Preferably, as attached Figure 4 As shown in , the adjustment transmission structure 62 includes a second transmission gear 621, the second transmission gear 621 is fixedly sleeved on the outside of the sleeve 41, the second transmission gear 621 is meshed with a second rack 622, and the two second racks 622 are symmetrically fixedly connected to the two ends of the movable frame 31, and the second rack 622 is arranged horizontally. That is, the movement of the movable frame can simultaneously drive the two walking mechanisms symmetrical about the chassis frame to adjust synchronously, and correspondingly, the other symmetrical movable frame can drive the two walking mechanisms on the other side to adjust synchronously. Under the condition that the movable frames located on both sides of the pile driver body are ensured to move close synchronously, the four walking mechanisms can be ensured to adjust the angle and posture synchronously, and due to the structural constraints of the transmission structure and the adjustment mechanism, the degree of synchronous adjustment is guaranteed to be consistent, thereby fully ensuring the stability of the chassis during the adjustment process and ensuring the precise and stable assembly connection.

[0043] The outer end surface of the walking wheel is provided with a buffer wear-resistant component 22, and the buffer wear-resistant component 22 has a built-in pressure sensing module, and the pressure feedback signal output of the pressure sensing module is electrically connected to the drive control module of the power device. Preferably, the buffer wear-resistant component 22 is set as an annular structure, and adopts a highly elastic rubber structure or annular airbag to buffer the support, and at the same time forms a cavity inside. When the annular buffer wear-resistant component 22 is completely in contact with the ground, it is compressed to a certain extent by pressure, and the air in the internal cavity is squeezed out to form a certain negative pressure cavity, so that the atmospheric pressure presses the walking wheel against the ground to ensure the stability of the support. The built-in pressure sensing module is evenly arranged on the annular contact surface on the bottom side, and the degree of contact with the ground and the force distribution are obtained through pressure feedback, so as to feedback control the progress of the adjustment and ensure that the final adjustment is the best support state.

[0044] Guide frames 7 are also provided on the left and right sides of the chassis frame, respectively, for guiding the walking mechanism to guide and limit the walking wheels during the switching to the walking mode. The front and rear sides of the surface are arranged as inclined surfaces, corresponding to the front and rear walking wheels respectively. In the process of the swing arm driving the walking wheels to swing from the front and rear sides to the left and right sides, the walking wheels will contact with the inclined guide sliding surface, and finally fit and limit with the lateral vertical surface, thereby improving the accuracy of adjustment and ensuring the stability of the movement of the chassis frame.

[0045] The method for mobilizing and assembling the pile driver chassis with high efficiency mobilization and assembly comprises the following steps:

[0046] S1. Adjust the posture of the chassis frame 1 and move it close to the pile driver body 5 in a walking state until the multiple plug-in positioning structures on it correspond to the positions of the reserved connection structures on the pile driver body 5; when actually transferring the working position, the pile driver body is separated from the chassis, and the body is transported to the target position by hoisting and positioned. The chassis frame is then switched to a walking state, moved to the target position and assembled with the pile driver body. Since the working point of the pile driver has been determined, the chassis frame only needs to be accurately positioned relative to the pile driver position and assembled.

[0047] S2, the power device works, drives multiple plug-in positioning structures to plug in with corresponding connection structures at the same time, and drives the pressure-adding and tightening structures to press together, and drives the control-adjusting mechanism 4 to adjust the posture of the walking mechanism 2 in a coordinated manner; it realizes the rapid assembly and synchronous switching of the supporting form, improves the assembly efficiency, and can quickly enter the working state

[0048] S3. According to the actual terrain feedback, the walking mechanism is adjusted to a suitable position and posture relative to the chassis frame 1 and the ground, and the switching of the support form is completed to ensure that the chassis frame 1 supported by multiple walking mechanisms is stable relative to the ground. The pressure sensing feedback controls the adjustment progress and stops the adjustment at the optimal position, reducing unnecessary adjustment steps and further improving efficiency.

[0049] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the above principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
