[0039] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0040] The rust removing vehicle chassis and the rust removing vehicle of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figure 1 As shown, the present invention provides a rust removal vehicle chassis, wherein the rust removal vehicle chassis comprises:

[0042] Frame 1;

[0043] The axle assembly includes a front axle 201 and a rear axle 202 respectively arranged at the front and rear ends of the frame 1. The front axle 201 and the rear axle 202 both include a steering mechanism 21, a first steering knuckle 22 and a second steering knuckle. The first steering knuckle 22 and the second steering knuckle are rotatably arranged on opposite sides of the frame 1 and are both equipped with a tire driving mechanism 3. The steering mechanism 21 is arranged on the frame 1 and has two driving ends, and the two driving ends are drivingly connected to the first steering knuckle 22 and the second steering knuckle in a one-to-one correspondence.

[0044] When the rust removal vehicle uses the above-mentioned rust removal vehicle chassis, the rust removal vehicle chassis includes a frame 1 and an axle assembly, and the axle assembly includes a front axle 201 and a rear axle 202 respectively arranged at the front and rear ends of the frame 1. Since the front axle 201 and the rear axle 202 of the rust removal vehicle chassis both include a steering mechanism 21, a first steering knuckle 22 and a second steering knuckle, the front and rear wheels of the rust removal vehicle can be swung at a certain angle respectively by controlling the steering mechanisms 21 of the front axle 201 and the rear axle 202, and in conjunction with the tire drive mechanism 3 on each steering knuckle, the four-wheel steering and four-wheel drive of the rust removal vehicle chassis can be realized. Compared with the existing rust removal In the vehicle chassis structure, the rear wheels are driven and the front wheels are steered. The rust removal vehicle chassis of the present invention allows the rear wheels and the front wheels to steer in different directions or angles. This coordinated work can significantly reduce the lateral swing and yaw angle of the rust removal vehicle, thereby accelerating the flexibility of low-speed turning and reducing the turning radius, effectively improving the passability of the rust removal vehicle in a narrow space, reducing the difficulty of operating the rust removal vehicle, and the four-wheel four-wheel drive solution can also improve the driving stability of the rust removal vehicle. On slippery, muddy and complex roads, the rust removal vehicle can be effectively prevented from slipping or losing control by reasonably distributing the driving force of the four tire drive mechanisms 3.

[0045] Preferably, the structure of the rear axle 202 can be consistent with that of the front axle 201 , which can facilitate assembly and reduce material costs.

[0046] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the steering mechanism 21 includes two telescopic driving members 211, the fixed ends of the two telescopic driving members 211 are both hinged to the frame 1, and the telescopic ends of the two telescopic driving members 211 are arranged away from each other and are respectively hinged to the first steering knuckle 22 and the second steering knuckle in a one-to-one correspondence. When the rust removal vehicle performs a steering action, the two telescopic driving members 211 on the same axle, one cylinder rod extends, and the other cylinder rod retracts to achieve tire steering. It can be understood that the conventional steering system uses a single steering tie rod, and the steering tie rod is respectively connected to the steering knuckles on both sides. The driver turns the steering wheel to control the left and right movement of the steering tie rod to control the wheel swing, while the first steering knuckle 22 and the second steering knuckle in the present application are both equipped with independent telescopic driving members 211, and the telescopic driving member 211 can be connected to the frame 1, the overall structural strength of the axle assembly is better, and the telescopic driving member 211 can swing synchronously, and the pressure angle between the telescopic driving member 211 and the corresponding steering knuckle is smaller, which can reduce the steering force required for steering.

[0047] Specifically, the telescopic drive member 211 is preferably a cylinder to adapt to the harsh working environment of the rust removal vehicle. By arranging a fuel tank, a hydraulic pump, a controller with a communication function and a corresponding electromagnetic control valve group on the frame 1, automatic control of the cylinder can be achieved. The operator only needs to input the corresponding control signal to the controller, and the controller controls the formation of the cylinder by controlling the on and off of each electromagnetic valve in the electromagnetic control valve group, thereby controlling the swing angle of the steering knuckle. Furthermore, the controller can be equipped with a wireless communication module, and the operator can send instructions to the controller at a location far away from the rust removal vehicle to achieve remote control of the rust removal vehicle. Accordingly, the cab on the frame 1 can be cancelled, further reducing the size of the rust removal vehicle, and being more suitable for operation in a narrow space. Of course, it is also possible for the telescopic drive member 211 to be arranged in other forms such as an electric push rod and a screw mechanism.

[0048] Specifically, the telescopic driving member 211 is connected to the vehicle frame 1 and the steering knuckle via a pin shaft, which is convenient for assembly and maintenance.

[0049] Specifically, the telescopic drive components 211 of the front and rear axles are built into the space between the frame 1 and the front and rear axles, which provides good protection for the structure of the telescopic drive components 211 itself, thereby preventing the telescopic drive components 211 from being damaged by collision during harsh dock operations, causing the chassis to fail to work properly.

[0050] like Figure 2 and Figure 3 As shown, in the embodiment of the present invention, the first steering knuckle 22 and the second steering knuckle are both formed with a first articulated seat 221 and a second articulated seat 222 spaced apart along the height direction of the vehicle frame 1, the first articulated seat 221 is correspondingly articulated with the telescopic end of the telescopic driving member 211, and the steering mechanism 21 also includes a steering link 212, and the two ends of the steering link 212 are respectively articulated with the first steering knuckle 22 and the second articulated seat 222 of the second steering knuckle in a one-to-one correspondence. The setting of the steering link 212 realizes the rigid connection between the first steering knuckle 22 and the second steering knuckle on the same axle. When one of the first steering knuckle 22 and the second steering knuckle swings, under the traction of the steering link 212, the other will also swing with the same amplitude, thereby ensuring the synchronization of the steering of the left and right wheels of the rust removal vehicle.

[0051] It should be noted that the steering amplitudes of the front axle 201 and the rear axle 202 may be the same or different. Different turning radii may be obtained by controlling the different steering amplitudes of the front axle 201 and the rear axle 202, thereby adapting to various complex road conditions.

[0052] like Figure 3As shown, in the embodiment of the present invention, the first articulated seat 221 includes two first ear plates 221a spaced apart in the height direction of the vehicle frame 1, and the telescopic end of the telescopic driving member 211 is provided with a sleeve portion 211a, which is placed between the two first ear plates 221a and connected in series with the two first ear plates 221a through a pin. When the telescopic driving member 211 is extended or retracted, the telescopic driving member 211 acts on the two first ear plates 221a of the first articulated seat 221 through the pin, and the upper and lower ends of the pin are both in a stressed state, which can achieve symmetry of the torque on the upper and lower sides, making the steering process smoother.

[0053] like Figure 3 As shown, in the embodiment of the present invention, two connecting parts 212a are arranged at intervals along the height direction of the frame 1 at both ends of the steering link 212, and the two connecting parts 212a are connected in series to the upper and lower sides of the second hinge seat 222 through a pin shaft, and the hinge point of the second hinge seat 222 is horizontally offset from the hinge point of the first hinge seat 221. Similar to the function of the first hinge seat 221, the two connecting parts 212a of the steering link 212 can also achieve moment symmetry on the upper and lower sides, and by setting the second hinge seat 222 as a single second ear plate, the interval between it and the first hinge seat 221 can be increased, which is convenient for operators to weld and assemble the second hinge seat 222 during the production process; the hinge point of the second hinge seat 222 is horizontally offset from the hinge point of the first hinge seat 221, which can avoid interference between the pin shafts on the two, and is convenient for operators to disassemble or assemble the axle assembly.

[0054] Specifically, the steering link 212 includes two connecting rods and a reinforcing rib connecting the two connecting rods, the two connecting rods are flat, and the ends of the two connecting rods exceed the reinforcing rib to form a connecting portion 212a. Of course, the present invention is not limited to this, and in other embodiments, the steering link 212 may also use a hinge or other connection forms.

[0055] like Figure 3 As shown, in the embodiment of the present invention, the first steering knuckle 22 and the second steering knuckle both include a mounting base plate 223, a first protective plate 224, a second protective plate 225 and two connecting plates 226, the two connecting plates 226 are respectively arranged at the upper and lower ends of the mounting base plate 223, and a steering shaft 227 for connecting the frame 1 is passed through the two connecting plates 226, the first protective plate 224 and the second protective plate 225 are respectively arranged at the front and rear sides of the mounting base plate 223, the mounting base plate 223 can be used for the installation of the tire drive mechanism 3, and the rotating drive component 31 in the tire drive mechanism 3 is placed in a protective space enclosed by the first protective plate 224, the second protective plate 225 and the two connecting plates 226 to reduce the risk of the rotating drive component 31 being hit by debris.

[0056] Specifically, see Figure 4The frame 1 includes a frame body 11 and a steering connector 12. The frame body 11 includes two parallel mounting vertical plates. A bottom plate and a plurality of reinforcing cross plates are connected between the two mounting vertical plates. The plurality of reinforcing cross plates separate the frame body 11 into a plurality of accommodating spaces. The plurality of accommodating spaces are used to respectively accommodate various actuators of the rust removal vehicle, such as a high-pressure water pump, a hydraulic oil pump, etc., and windows are also provided between the connecting cross plates for laying pipelines (the pipelines can be any one or a combination of the following: electric wires, water pipes, and oil pipes). Both ends of the mounting vertical plates are provided with downward mounting openings, and the steering connector 12 is embedded in the mounting openings. Both ends of the steering connector 12 extend laterally from the mounting vertical plates, and two corresponding mounting portions 121 are formed on the two connecting plates 226 corresponding to the steering knuckles.

[0057] Further, see Figure 3 and Figure 4 , both ends of the steering shaft 227 are sleeved with a connecting end cover, a first connecting ring and a second connecting ring, the connecting end cover, the connecting plate 226 and the first connecting ring are fixedly connected by bolt connectors, and the connecting portion 212a and the second connecting ring are fixedly connected by bolt connectors to realize the articulation of the steering knuckle and the steering connecting body 12. The connecting end cover is used to axially limit the steering shaft 227 to prevent the steering shaft 227 from coming out, the first connecting ring and the second connecting ring are used to radially limit the steering shaft 227, and the first connecting ring and the second connecting ring are set to be matched with the steering shaft 227 with high precision, so as to reduce the shaking of the steering shaft 227 and the entire steering knuckle.

[0058] Furthermore, an inclined reinforcing rod is welded between the steering connector 12 and the mounting vertical plate to improve the structural strength of the vehicle frame 1 .

[0059] like Figure 3 As shown, in the embodiment of the present invention, one of the first protective plate 224 and the second protective plate 225 is provided with a first hinge seat 221 and a second hinge seat 222, and the other is provided with a wiring hole 224a for the pipeline to pass through.

[0060] Preferably, the first protective plate 224 of the front axle 201 is located on the front side of the mounting substrate 223, the second protective plate 225 of the front axle 201 is located on the rear side of the mounting substrate 223, the rear axle 202 is symmetrically arranged with the front axle 201, the first protective plate 224 of the rear axle 202 is located on the rear side of the mounting substrate 223, and the second protective plate 225 of the rear axle 202 is located on the front side of the mounting substrate 223; the first protective plate 224 is provided with a wiring hole 224a for the passage of pipelines.

[0061] like Figure 4As shown, in the embodiment of the present invention, a limit block 13 is further provided on the frame 1, and the limit block 13 is used to abut against the connecting plate 226 of the steering knuckle when the steering knuckle is turned to the maximum steering angle, so as to avoid over-steering causing the tire body 32 of the tire drive mechanism 3 to collide with the frame 1.

[0062] Specifically, the limit blocks 13 are arranged at both ends of the steering connector 12, and four limit blocks 13 are arranged corresponding to the front axle 201 and the rear axle 202 to meet the needs of four-wheel steering.

[0063] Specifically, the limit block 13 can be elastically compressed to provide a buffer for the steering knuckle, avoid rigid collision, and protect the steering knuckle.

[0064] Specifically, the first hinge seat 221 and the second hinge seat 222 are both formed with a clamping opening on one side facing the mounting base plate 223, and the clamping opening can be used for the second protective plate 225 to be embedded. This clamping method can increase the contact area between the two hinge seats and the second protective plate 225 and the mounting base plate 223, thereby improving the structural strength of the steering knuckle after welding; see Figure 3 The position of the wiring hole 224a is exactly opposite to the oil port of the rotating driving member 31. The pipeline directly passes through the wiring hole 224a and connects with the oil port of the rotating driving member 31 to avoid a large bend in the pipeline at the second protective plate 225, thereby ensuring the reliability of oil supply.

[0065] Furthermore, the width of the second protective plate 225 along the horizontal direction is greater than the width of the first protective plate 224 along the horizontal direction, and the two connecting plates 226 are inclined toward one side of the first protective plate 224 .

[0066] In the embodiment of the present invention, the tire driving mechanism 3 includes a rotary driving member 31 and a tire body 32, wherein the rotary driving member 31 is arranged on the first steering knuckle 22 or the second steering knuckle and drives the tire body 32, wherein the rotary driving member 31 is configured as a hydraulic motor, which can provide high torque at low speed, and is very suitable for equipment that needs to move slowly and carry heavy loads, such as a rust removal vehicle, and the hydraulic motor still has high reliability even in harsh environments. Of course, the present invention is not limited to this, and in other embodiments, the rotary driving member 31 can also be configured as an electric motor or a pneumatic motor.

[0067] like Figure 4 As shown, in an embodiment of the present invention, the chassis of the rust removal vehicle also includes a slewing mechanism 4 arranged on the frame 1, and the slewing mechanism 4 includes a slewing cylinder 41, a fixed seat 42 and a rotating seat (not shown in the figure), and the rotating seat is located between the front axle 201 and the rear axle 202, and the fixed seat 42 is located on the rear side of the rotating seat. The rotating seat can be rotatably set and used to install the arm device of the rust removal vehicle. The upper end of the arm device is used to set the rust removal device, and the piston rod of the slewing cylinder 41 is connected to the fixed seat 42, and the cylinder barrel of the slewing cylinder 41 is connected to the rotating seat.

[0068] In the existing rust removal vehicle, a rotary reducer is mainly used as a driving part and the rotating seat is driven to rotate through a gear transmission mechanism. Due to the tooth side clearance when the gears are meshed, a large impact will be generated during the process of the rotating seat starting to rotate or rotating to change direction, resulting in poor stability and micro-motion of the rotating seat. The cleaning disc at the top of the rust removal device is difficult to quickly and accurately fit the rust removal surface, resulting in low quality and efficiency of rust removal. The present invention drives the rotating seat to rotate horizontally through the steering mechanism 21, so that the cleaning disc of the rust removal device is close to the working area. The rotary oil cylinder 41 adopts stepless adjustment, and the transmission process is more stable.

[0069] In addition, the cylinder barrel of the rotary cylinder 41 is connected to the rotating seat as the driving end, and the piston rod is connected to the fixed seat 42. The cylinder barrel part has a larger force-bearing area and can withstand a larger workload. The cylinder barrel part of the rotary cylinder 41 can be designed as needed to achieve a longer stroke.

[0070] Furthermore, the hinge points on the fixed seat 42 and the rotating seat for connecting the rotary cylinder 41 are arranged at intervals along the width direction of the frame 1, see Figure 4 This arrangement can make the pressure angle between the extension direction of the rotary cylinder 41 and the rotation direction of the rotating seat smaller, thereby reducing the load of the rotary cylinder 41 and allowing the rotating seat to obtain a larger rotation range.

[0071] In order to achieve the above objectives, the present invention further provides a rust removal vehicle, wherein the rust removal vehicle includes the above rust removal vehicle chassis.
