Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery, and more particularly to a crawler chassis and a crawler vehicle. Background Art

[0002] Existing spider vehicles and excavators mostly use integral or combined crawler walking chassis. Common crawler walking chassis adopt H-shaped or X-shaped crawler tracks. This structure has large external dimensions, uses a lot of materials, and has high mass. For spider vehicles, however, the chassis is required to be small, light, and narrow, with good overall passability and good stability. Especially for high-meter sections, the length of the whole machine is longer, and to achieve better stability, the length requirement for the chassis is also longer. For example, when passing through a climbing section or a low-lying section, when the chassis is moving, at the junction of the climbing section or the low-lying section and the horizontal section, part of the chassis will be in contact with the climbing section or the low-lying section, and part of the chassis will be suspended in the air. Therefore, in order to ensure the stability of the vehicle, higher requirements are also placed on the chassis length.

[0003] In summary, how to effectively solve the problem of balancing the stability of tracked vehicles with the small size requirement of the tracked chassis is a problem that currently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide a crawler chassis and a crawler vehicle, the structural design of which can effectively solve the problem of difficulty in balancing the stability of the crawler vehicle and the small size requirement of the crawler chassis.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] Second crawler mechanism;

[0008] a transition bracket, one end of which is connected to the second crawler mechanism, and the other end of which is rotatably connected to the other end of the chassis, with a rotation axis parallel to the chassis;

[0009] A driving component is connected to the transition bracket to drive the transition bracket to rotate relative to the chassis.

[0010] Optionally, in the above-mentioned crawler chassis, the driving component is a telescopic cylinder, one end of the telescopic cylinder is rotatably connected to the chassis, and the other end is rotatably connected to the transition bracket.

[0011] Optionally, in the above-mentioned crawler chassis, a mounting groove is provided on the transition bracket, and one end of the telescopic cylinder is placed in the mounting groove and hinged to the transition bracket.

[0012] Optionally, in the above-mentioned crawler chassis, a support is provided on the side of the chassis, and the transition bracket is rotatably connected to the support.

[0013] Optionally, the above-mentioned crawler chassis also includes a first steering mechanism, which is arranged at one end of the transition bracket, and the output end of the first steering mechanism is connected to the second crawler mechanism to drive the second crawler mechanism to rotate, and the rotation axis of the first steering mechanism is perpendicular to the second crawler mechanism.

[0014] Optionally, the above-mentioned crawler chassis further includes a transition connecting plate, which is fixedly connected to the first steering mechanism, and a transition connecting seat is provided on the top surface of the transition connecting plate to connect with one end of the transition bracket.

[0015] Optionally, in the above-mentioned crawler chassis, the transition connecting plate is rotatably connected to the transition bracket, and the rotation axis is parallel to the transition connecting plate.

[0016] Optionally, in the above crawler chassis, the first crawler mechanism is hinged to the chassis.

[0017] Optionally, in the above-mentioned crawler chassis, the first crawler mechanism is rotatably connected to the chassis through a second steering mechanism, and the rotation axis of the second steering mechanism is perpendicular to the first crawler mechanism.

[0018] The crawler chassis provided by the present invention includes a chassis, a first crawler mechanism, a second crawler mechanism, a transition bracket, and a drive component. The first crawler mechanism is provided at one end of the chassis, the transition bracket is rotatably connected to the other end of the chassis with a rotation axis parallel to the chassis, and the transition bracket is connected to the second crawler mechanism. The drive component is rotatably connected to the transition bracket to drive the transition bracket to rotate relative to the chassis.

[0019] The crawler chassis provided by the present invention is provided with a first crawler mechanism and a second crawler mechanism. The second crawler mechanism can rotate relative to the chassis along with the transition bracket under the drive of the driving component, thereby achieving up and down floating. Therefore, when passing through a pothole section or a climbing section or when the first crawler mechanism and the second crawler mechanism have different slopes, the first crawler mechanism remains on the ground and drives the second crawler mechanism to float according to the terrain through the driving component. Then, the second crawler mechanism can also always be on the ground, so that the whole vehicle will not be suspended in the air. In summary, the crawler chassis achieves stable walking in pothole sections or climbing sections through the cooperation of the first crawler mechanism and the second crawler mechanism. In addition, the walking occupies a small space, uses less material, and saves costs.

[0020] In order to achieve the above object, the present invention further provides a crawler vehicle comprising any one of the above crawler chassis. Since the above crawler chassis has the above technical effects, the crawler vehicle having the crawler chassis should also have corresponding technical effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The embodiment of the present invention discloses a crawler chassis and a crawler vehicle, which take into account both the stability of the crawler vehicle and the small size of the crawler chassis.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The crawler chassis provided by the present invention is applicable to, but not limited to, crawler vehicles, including but not limited to spider vehicles and excavators. The present invention primarily enhances the chassis's stability by providing a first crawler mechanism and a second crawler mechanism. The specific structures of each crawler mechanism and the chassis structure can be referenced to conventional chassis and crawler structures. The following embodiments primarily illustrate how the first crawler mechanism and the second crawler mechanism are connected to the chassis.

[0034] See also Figure 1-Figure 5 , Figure 1 This is a schematic structural diagram of a crawler chassis according to a specific embodiment of the present invention; Figure 2 for Figure 1 A schematic structural diagram of the assembly of the second crawler mechanism, the first steering mechanism and the transition connection plate; Figure 3 for Figure 2 Schematic diagram of the explosion structure; Figure 4 It is a structural diagram of the transition connection plate; Figure 5 Schematic diagram of the structure of the transition bracket; Figure 6 It is a structural diagram of the first crawler mechanism.

[0035] In a specific embodiment, the crawler chassis provided by the present invention includes a chassis 1, a first crawler mechanism 2, a second crawler mechanism 3, a transition bracket 4, and a drive component 5. The chassis 1 is the main structure of the crawler chassis, and the first crawler mechanism 2 and the second crawler mechanism 3 are respectively mounted on the chassis 1. Specifically, the first crawler mechanism 2 is arranged at one end of the chassis 1, and the second crawler mechanism 3 is connected to the chassis 1 via the transition bracket 4. It is understood that the transition bracket 4 and the second crawler mechanism 3 can be directly or indirectly connected. The transition bracket 4 is rotatably connected to the other end of the chassis 1, and the rotation axis is parallel to the chassis 1. The second crawler mechanism 3 is connected to the transition bracket 4. The drive component 5 is rotatably connected to the transition bracket 4 to drive the transition bracket 4 to rotate relative to the chassis 1. In other words, the drive component 5 is used to drive the transition bracket 4 to rotate relative to the chassis 1 around the rotation axis parallel to the chassis 1, thereby driving the second crawler mechanism 3 on the transition bracket 4 to rotate relative to the chassis 1, so as to achieve the up and down floating of the second crawler mechanism 3.

[0036] The crawler chassis provided by the present invention is provided with a first crawler mechanism 2 and a second crawler mechanism 3. The second crawler mechanism 3 can rotate relative to the chassis 1 along with the transition bracket 4 under the drive of the driving component 5, thereby achieving up and down floating. Therefore, when passing through a pothole section or a climbing section or when the first crawler mechanism 2 and the second crawler mechanism 3 have different slopes, the first crawler mechanism 2 remains on the ground and drives the second crawler mechanism 3 to float according to the terrain through the driving component 5. Then, the second crawler mechanism 3 can also always be on the ground, so that the whole vehicle will not be suspended in the air. In summary, the crawler chassis 1 achieves stable walking in pothole sections or climbing sections through the cooperation of the first crawler mechanism 2 and the second crawler mechanism 3. In addition, the walking structure occupies little space, uses less material, and saves costs.

[0037] In one embodiment, the driving component 5 is a telescopic cylinder, one end of which is rotatably connected to the chassis 1 and the other end of which is rotatably connected to the transition bracket 4. Specifically, the telescopic cylinder can be a hydraulic cylinder, a pneumatic cylinder, or other device. The telescopic movement of the telescopic cylinder drives the reliable rotation of the transition bracket 4. Using a telescopic cylinder for driving the transition bracket 4 offers a simple structure, easy installation, minimal space requirements, and stable and reliable driving force. In other embodiments, the transition bracket 4 can also be driven by a torque output device such as a motor.

[0038] Furthermore, the transition bracket 4 is provided with a mounting slot 41, into which one end of the telescopic cylinder is placed and hingedly connected. The provision of mounting slot 41 provides clearance for the telescopic cylinder, further conserving space. In other embodiments, a lug or other structure may be provided on the transition bracket 4 to provide a hinged connection to one end of the telescopic cylinder.

[0039] In one embodiment, a support 11 is provided on the side of the chassis 1, and the transition bracket 4 is rotatably connected to the support 11. The provision of the support 11 facilitates a rotatable connection with the transition bracket 4, specifically, by means of a hinged connection. Furthermore, the support 11 is located on the side of the chassis 1, specifically the side facing away from the second crawler mechanism 3, fully utilizing the space within the chassis 1. In other embodiments, the transition bracket 4 may also be directly rotatably connected to the chassis 1.

[0040] In one embodiment, the crawler chassis also includes a first steering mechanism 6, which is provided at one end of the transition bracket 4, and the output end of the first steering mechanism 6 is connected to the second crawler mechanism 3 to drive the second crawler mechanism 3 to rotate, and the rotation axis of the first steering mechanism 6 is perpendicular to the second crawler mechanism 3. By providing the first steering mechanism 6 to drive the second crawler mechanism 3 to rotate, the second crawler mechanism 3 can not only rotate around a rotation axis parallel to the chassis 1, but also rotate around a rotation axis perpendicular to the second crawler mechanism 3, that is, it can realize walking and steering functions, so that the crawler chassis has more comprehensive performance. The specific structure of the first steering mechanism 6 can refer to the structural setting of the conventional steering mechanism, and is not specifically limited here. It can be driven by a telescopic cylinder such as an oil cylinder, or by a slewing reducer.

[0041] Specifically, the first steering mechanism 6 can realize 360-degree rotation, thereby driving the second crawler mechanism 3 to rotate within a range of 360 degrees, so as to drive the entire vehicle to turn accordingly.

[0042] In one embodiment, the crawler chassis further includes a transition plate 7, which is fixedly connected to the first steering mechanism 6. A transition seat 8 is provided on the top surface of the transition plate 7 for connection to one end of the transition bracket 4. The connection between the first steering mechanism 6 and the transition bracket 4 is achieved through the transition plate 7. When the transition bracket 4 rotates relative to the chassis 1 about a rotation axis parallel to the chassis 1, driven by the drive component 5, the transition plate 7 connected thereto rotates accordingly, thereby driving the first steering mechanism 6 connected to the transition plate 7 to rotate accordingly, and the second crawler mechanism 3 connected to the output end of the first steering mechanism 6 to rotate accordingly. Specifically, the transition bracket 4 is provided with a first mounting hole 42 and a second mounting hole 43 at each end. The first mounting hole 42 is used for rotational connection with the chassis 1, specifically, it can be rotationally connected to the support 11 on the chassis 1. The second mounting hole 43 is used for connection to the second crawler mechanism 3, specifically, it can be connected to the transition seat 8 on the transition plate 7. In this embodiment, the second crawler structure 3 is connected to the transition bracket 4 in sequence through the first steering mechanism 6 and the transition plate 7. In the case where the first steering mechanism 6 is not provided, the second crawler structure 3 may also be directly connected to the transition bracket 4 .

[0043] In one embodiment, the transition connection plate 7 is rotatably connected to the transition bracket 4, and the rotation axis is parallel to the transition connection plate 7. Specifically, the transition connection plate 7 and the transition bracket 4 can be hinged. Then, when the transition bracket 4 is rotated to different angles relative to the chassis 1, the transition connection plate 7 can adaptively rotate relative to the transition bracket 4, so that the second crawler mechanism 3 always maintains a consistent angle with the ground. In other embodiments, since the transition bracket 4 can be rotated to adjust the angle, the transition connection plate 7 can also be fixedly connected to the transition bracket 4, and the transition bracket 4 can be driven to rotate by the driving component 5, thereby realizing active adjustment of the angle of the second crawler mechanism 3.

[0044] In one embodiment, the first crawler mechanism 2 is hinged to the chassis 1. Based on the undulations of the ground, the first crawler mechanism 2 can rotate relative to the chassis 1, with its axis of rotation parallel to the chassis 1, to adapt to the ground angle and maintain ground contact. In other words, the angle of the first crawler mechanism 2 can be adaptively adjusted to the ground angle, allowing for better ground contact and enhancing the stability of the crawler chassis. Specifically, a crawler connector 9 can be provided on the first crawler mechanism 2, which is hinged to the chassis 1 via the crawler connector 9.

[0045] In one embodiment, the first crawler mechanism 2 is rotatably connected to the chassis 1 via a second steering mechanism, and the rotation axis of the second steering mechanism is perpendicular to the first crawler mechanism 2. By providing a second steering mechanism to drive the first crawler mechanism 2 to rotate, the first crawler mechanism 2 can rotate around a rotation axis perpendicular to the second crawler mechanism 3, that is, it can realize walking and steering functions, so that the crawler chassis has more comprehensive performance. The specific structure of the second steering mechanism can refer to the structural setting of a conventional steering mechanism and is not specifically limited here. It can be driven by a telescopic cylinder such as an oil cylinder or by a rotary reducer.

[0046] Based on the crawler chassis provided in the above embodiments, the present invention further provides a crawler vehicle, which includes any one of the crawler chassis in the above embodiments. Since the crawler vehicle adopts the crawler chassis in the above embodiments, the beneficial effects of the crawler vehicle can be referred to the above embodiments. Figure 7 , the crawler vehicle can be a spider vehicle.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
