Description

Technical Field

[0001] This utility model relates to the field of construction machinery and equipment technology, and more specifically, it relates to a universal electric chassis for pile drivers. Background Technology

[0002] As an important construction equipment in civil engineering, the sluice gate loader mainly consists of three parts: chassis, main frame, and power system, each playing a crucial functional role. However, in practical applications, these components still have many limitations and shortcomings.

[0003] The chassis, serving as the moving and supporting foundation for the insert press, is currently mainly divided into three types: rail-mounted chassis, hydraulic walking chassis, and tracked chassis. Rail-mounted chassis are commonly used in softer geological conditions. Under these conditions, the rails provide better support and guidance, ensuring the accuracy of the insert press's movement and operation. Rail-mounted chassis have a relatively simple structure and lower cost, but their adaptability to complex terrain is not as good as tracked chassis. Hydraulic walking chassis offer convenient and flexible movement, allowing for 360° rotation, facilitating turning and position adjustments on the construction site. The hydraulic system provides stable power, making the machine's movement and operation smoother. Tracked chassis are suitable for harder geological conditions, offering good passability and stability, enabling movement and operation on more complex terrain. Their track structure distributes the machine's weight, reducing pressure on the ground and preventing the machine from sinking into the ground during operation. Nevertheless, none of these chassis types offer automatic driving capabilities, limiting the adaptability and application range of the insert press in different scenarios.

[0004] The main frame, as the main structure of the plate-inserting machine, is responsible for supporting and installing other components. Its height and driving depth have certain ranges, generally 20-30 meters in height and 20-25 meters in driving depth. The main frame is usually welded from steel pipes or structural steel, possessing high strength and rigidity. However, to meet the requirements of the hanging hammer, the main frame is designed to be quite bulky, resulting in a large overall size and weight for the plate-inserting machine. Typically, existing plate-inserting machines are 12 meters long, 8 meters wide, and weigh 22-30 tons, causing significant inconvenience for installation and transportation.

[0005] In terms of the power system, the vibratory hammer is one of the core components of the plate-inserting machine. It generates excitation force by being powered to drive the insertion tube into the soil. Its frequency and amplitude can be adjusted according to geological conditions and construction requirements to achieve the best plate-inserting effect. However, the vibratory hammer produces tremendous hammering noise, causing serious noise pollution.

[0006] In terms of application scenarios, traditional electric chassis have a relatively high ground pressure, making them unable to pass through soft soil sites such as mud and wetlands.

[0007] In summary, existing board insertion machines have significant shortcomings in areas such as automated driving, installation and transportation, noise pollution, and adaptability. Therefore, it is necessary to innovate and improve these machines to overcome these deficiencies. Utility Model Content

[0008] To address this problem in practical applications, the purpose of this utility model is to propose a universal electric chassis for pile drivers, thereby improving the performance and adaptability of the pile driver. The specific solution is as follows:

[0009] A universal electric chassis for pile drivers includes a tracked drive chassis, a load-bearing platform, and an unmanned control system, wherein the load-bearing platform is mounted on the tracked drive chassis.

[0010] The unmanned control system includes a sensor system, a control system, a communication system, and an execution system. The control system is connected to the sensor system and the execution system through the communication system. The sensor system includes several sensor groups installed on a tracked drive chassis or a carrier platform for collecting environmental information around the electric chassis.

[0011] Furthermore, the tracked drive chassis includes a main beam, tracks, and a track drive transmission mechanism. Guide wheels and drive wheels are respectively mounted at the four corners of the main beam. The drive wheels are driven and connected by the track drive transmission mechanism. Track rollers and support rollers of the whole machine are respectively installed on the upper and lower parts of both sides of the main beam. Tracks with both sides are mounted on the guide wheels, track rollers, support rollers, and drive wheels.

[0012] Furthermore, the load-bearing platform is located in the middle of the main beam and is arranged along the axial direction of the main beam, with tracks extending through both ends of the platform.

[0013] Furthermore, the application to the inserting plate machine also includes a main frame and a winch, both of which are installed on the carrying platform. The main frame is located directly above one side of the track on the carrying platform, and the winch is located on the carrying platform near the other side of the track.

[0014] Furthermore, the winch speed is 36-60 m / min.

[0015] Furthermore, the sensor group includes a position sensor, an attitude sensor, and a vision sensor.

[0016] Furthermore, the communication system adopts any one of 4G / 5G / ZigBee wireless communication methods.

[0017] Furthermore, the execution system includes a power system control component and a steering system control component. The power system control component is used to adjust the driving speed and power output of the electric chassis, and the steering system control component is used to control the steering of the electric chassis.

[0018] Furthermore, it also includes safety guardrails, which are installed on the upper part of the side of the chassis adjacent to the tracks.

[0019] Furthermore, it also includes a generator set output cable hanger, which is installed on the front, rear, or both sides of the support platform.

[0020] Furthermore, it also includes a pontoon structure, which comprises at least one pontoon installed at the bottom of the main beam.

[0021] Furthermore, the pontoon is made of wear-resistant plate and consists of several outer plates that surround the pontoon to form a box structure and several reinforcing plates located inside the box structure.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] (1) An electric chassis is adopted and an unmanned driving system is configured to realize unmanned driving, which can adapt to more usage scenarios and improve the versatility and applicability of the electric chassis;

[0024] (2) By using a winch to replace the vibratory hammer in the traditional plate inserter, the problem of noise pollution from the vibratory hammer is avoided, and the winch speed of the winch is increased, thus achieving efficient plate inserting.

[0025] (3) The electric chassis is used in the insertion machine and in conjunction with the winch. There is no need to consider the hanging hammer requirement or the need for additional counterweight, which ensures the working and walking stability of the electric chassis. The size and weight of the equipment are reduced, making it easier to install and transport.

[0026] (4) By setting a floating box structure at the bottom of the chassis, the ground pressure of the chassis is reduced, so that the electric chassis can meet all terrain conditions, such as wetlands, mudflats, and soft soil backfill. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Example 1

[0037] like Figure 1-3 As shown, a universal electric chassis for pile drivers includes a tracked drive chassis, a load-bearing platform 7, and an unmanned control system 8. The load-bearing platform 7 is mounted on the tracked drive chassis. The unmanned control system 8 is used to control the electric chassis to achieve unmanned driving. It includes a sensor system 81, a control system 82, a communication system 83, and an execution system 84. Both the sensor system 81 and the execution system 84 are mounted on the electric chassis.

[0038] Specifically, the tracked drive chassis preferably has a length and width of (3200-7000) * (2500-5500) m, and includes a main beam 1, tracks 2, and a track drive transmission mechanism (not shown in the figure). The main beam 1 is a rectangular frame structure formed of I-beams, and the weight of the tracked drive chassis is concentrated on the main beam 1, thus lowering the center of gravity. The tracks 2 are located on both sides of the main beam 1, and the width of the tracks 2 is preferably 600-900 mm, the pitch is 190 mm, and the front-to-rear center distance of the tracks 2 is preferably 4790 mm. The tracks 2 are connected to the main beam 1 via wheel hubs. Specifically, in one possible embodiment, guide wheels 3 and drive wheels 4 are respectively mounted at the four corners of the main beam 1. The drive wheels 4 are driven and connected by a track drive transmission mechanism. Track rollers 5 and support rollers 6 are respectively installed on the upper and lower parts of both sides of the main beam 1. Tracks 2 with both sides are mounted on the guide wheels 3, track rollers 5, support rollers 6 and drive wheels 4. The track drive transmission mechanism is used to drive the electric chassis and can be driven and connected to the guide wheels 3 and drive wheels 4. In this embodiment, its drive source is electric drive, such as motor, electric motor, etc.

[0039] It should be noted that the track drive transmission mechanism is an existing technology, such as the power drive and steering mechanism of the track chassis in a new type of cutting groove well drilling rig disclosed in CN105888546B. This application does not involve any improvement to it, so its specific structure and working principle will not be described in detail here.

[0040] In the unmanned control system 8, such as Figure 2 As shown, the control system 82 is connected to the sensor system 81 and the execution system 84 through the communication system 83.

[0041] Specifically, the sensor system 81 includes several sensor groups installed on the tracked drive chassis and / or the carrier platform 7 for collecting environmental information around the electric chassis. The sensor groups include a position sensor 811, an attitude sensor 812, and a vision sensor 813. The position sensor 811, such as using GPS or BeiDou systems, is used to accurately determine the position information of the electric chassis, including latitude, longitude, and altitude, to achieve positioning and navigation functions. The attitude sensor 812, such as using a gyroscope or accelerometer, can sense changes in the electric chassis's tilt and other attitude changes, ensuring stability during operation. The vision sensor 813, such as using a camera, can identify the growth status of surrounding crops, row spacing, obstacles, etc., providing visual information for agricultural machinery operations. It should be noted that the specific arrangement of each sensor group can be adjusted and determined according to actual usage conditions; this embodiment does not impose any limitations.

[0042] The control system 82, including a central controller, can be located in a monitoring center or as a handheld terminal. It receives information from several sensor groups, analyzes and processes it, and then issues control commands to the execution system 84. The control system 82 includes path planning and automatic obstacle avoidance for the electric chassis, ensuring that the equipment operates according to predetermined requirements. It should be noted that the central controller is prior art, and will not be described in detail here.

[0043] The communication system 83 adopts any wireless communication method such as 4G / 5G / ZigBee to realize data transmission between the electric chassis and the remote monitoring center or the operator's handheld terminal, so as to facilitate remote monitoring of machine status and remote transmission of operation commands.

[0044] The execution system 84 is specifically a track drive transmission mechanism, including a power system control component 841 and a steering system control component 842. The power system control component 841, such as a motor controller or engine speed governor, adjusts the travel speed and power output of the electric chassis according to the instructions transmitted from the control system 82. The steering system control component 842, such as an electric power steering system, precisely controls the steering of the electric chassis to achieve automatic steering function.

[0045] The working principle of the unmanned control system 8 is as follows: the sensor system 81 collects information such as the machine's position, attitude, and surrounding environment, and transmits this data to the control system 82; the central controller in the control system 82 uses control algorithms to analyze and process the data, such as planning the next action based on the position information and the preset work path, and making obstacle avoidance decisions based on the obstacle information detected by the vision sensor 813; then, the electric chassis status information can be sent to a remote monitoring center or handheld terminal through the communication system 83, while receiving remote control commands; finally, the control system 82 sends commands to the execution system 84, which drives the machine's power, steering, and working implements to achieve automatic unmanned operation.

[0046] In addition, the electric chassis includes a safety guardrail (not shown in the figure), which is installed on the upper part of the side of the chassis adjacent to track 2. The safety guardrail serves a protective function to ensure operational safety.

[0047] The electric chassis also includes a generator output cable bracket (not shown in the figure). The generator output cable bracket is installed at the front, rear or both sides of the bearing platform 7 to ensure that the cable does not interfere with the track 2 when moving, thus ensuring safe driving.

[0048] If manual driving is required in actual use, the electric chassis can also be equipped with a cab (not shown in the figure) to ensure a more comfortable environment for manual operation.

[0049] In this embodiment, the electric chassis has a total vehicle weight of 12-28T, a transport load of not less than 15t, a travel speed of 10-50m / min, and a chassis ground pressure control between 15.4-60.

[0050] Example 2

[0051] The chassis provided in this application is a general-purpose chassis that can adapt to various working scenarios, such as being used in jacking machines, geological exploration machines, cement mixing pile foundations, and as a transport trolley.

[0052] like Figure 4 As shown, when the electric chassis is applied to a plate inserter in this embodiment, it also includes a main frame 9 and a winch 10, both of which are installed on the upper part of the support platform 7. The main frame 9 is located directly above the track 2 on one side of the support platform 7, and weighs approximately 3.5T. The winch 10 is located on the support platform 7 near the track 2 on the other side, and weighs approximately 4T. The purpose of this arrangement is to ensure the balance of both sides when the electric chassis is moving or working, so that there is no need to add additional counterweights to the chassis to maintain balance, thus ensuring the working and moving stability of the electric chassis.

[0053] Specifically, the installation method of the main frame 9 and the winch 10 is as follows: the support platform 7 is located in the middle of the main beam 1 and is arranged along the axial direction of the main beam 1, with both ends extending through and outwards from the track 2. A mounting bracket (not shown in the figure) is provided on one side of the support platform 7, located above the track 2, with one end hinged to the support platform 7 and the other end fixed to the support platform 7. The main frame 9 is fixed to the mounting bracket to avoid interference with the movement of the track 2. The winch 10 is fixed to the other side of the support platform 7.

[0054] During operation, the main frame 9 is usually subjected to a reaction force of less than 10T, which is less than the weight of a single electric chassis and the main frame 9 (10.5T), to ensure that the inserting machine will not overturn when it moves and operates.

[0055] A winch 10 replaces the vibratory hammer used in traditional pile driver machines. The maximum pulling force of the winch 10 is 15T. The winch 10 avoids the hammering noise of the vibratory hammer, thus preventing noise pollution. It also enables rapid lifting and movement, and precise control of the pile driving speed, which helps improve construction efficiency and quality. Furthermore, the main frame 9 does not require a hanging hammer, allowing for a reduction in size and weight. This makes it suitable for different types of main frames and facilitates installation and transportation.

[0056] Furthermore, since the traditional winch speed is 10m / min, it is not suitable for the plate insertion machine. In this embodiment, the winch speed is 36-60m / min, which can achieve efficient plate insertion.

[0057] Example 3

[0058] like Figure 5 As shown, the chassis also includes a pontoon structure, which comprises at least one pontoon 11 installed at the bottom of the main beam. The number of pontoons 11 can be one, two, etc., but preferably the number of pontoons 11 is [number missing]. Figure 5 The image shows two floating boxes located at the bottom of the main beam.

[0059] In addition, the pontoon 11 can be easily assembled and disassembled by fixing it with bolts.

[0060] The pontoon 11 is made of wear-resistant steel plate, and as... Figure 6 As shown, the pontoon is composed of several outer plates 111 forming a box structure and several reinforcing plates 112 located inside the box structure. The box structure formed by the outer plates 111 is boat-shaped, and the reinforcing plates 112 inside the box structure are stacked in a cross shape to increase the overall strength of the pontoon.

[0061] The design of setting a floating box structure at the bottom of the chassis can reduce the ground pressure of the chassis. Table 1 shows the ground pressure of six tracked chassis with different axle weights, ground lengths, and ground widths.

[0062] Table 1

[0063]

[0064] As shown in Table 1, under the same weight and grounding length, the smaller the grounding width of the tracked chassis, the greater its grounding specific pressure. When pontoons 11 are added, the grounding specific pressure of the tracked chassis decreases, and the grounding specific pressure decreases further as the number of pontoons 11 increases.

[0065] Therefore, the pontoon structure enables the chassis to operate in muddy and wetland environments, thereby expanding the chassis's application range.

[0066] In addition, such as Figure 7 As shown, the floating box structure can also be applied to the plate insertion machine. When the plate insertion machine is working on a soft soil platform such as muddy or wetland, the floating box structure can be added to adapt to the plate insertion in muddy or wetland conditions.

[0067] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
