Abstract

This application provides a traveling device and a tunneling machine. The traveling device includes a track frame, a track section, a drive unit, and an elastic element. The track section is fitted onto the track frame and has track teeth, with multiple track teeth spaced apart on one side of the track section away from the track frame. The drive unit is mounted on the track frame and connected to the track section, and is used to drive the track section. The elastic element is disposed between some adjacent track teeth. The traveling device proposed in this application, by incorporating an elastic element between the track teeth, can simultaneously contact the mountain surface using both the track teeth and the elastic element under conditions of steep downhill slopes and hard rock. This increases the contact area between the traveling device and the mountain rock, combining the shear resistance between the track teeth and the hard rock with the frictional force between the elastic element and the hard rock, thereby improving the traveling device's adhesion to the mountain and reducing the risk of slippage.

Description

Technical Field

[0001] This application relates to the field of tunneling machine equipment technology, and more specifically, to a traveling device and a tunneling machine. Background Technology

[0002] Currently, when tunneling machines are excavating tunnels, they often encounter working conditions with steep downhill slopes and hard rock. Under such circumstances, the track teeth of the tunneling machine are difficult to penetrate into the rock, which can easily cause the tunneling machine to slide down, posing a safety hazard. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this application proposes a traveling device.

[0005] The second aspect of this application proposes a tunneling machine.

[0006] In view of the above, the first aspect of this application provides a traveling device, including a track frame, a track section, a drive section, and an elastic element; the track section is sleeved on the track frame and has track teeth, with a plurality of track teeth spaced apart on one side of the track section away from the track frame; the drive section is disposed on the track frame and connected to the track section, and is used to drive the track section for transmission; the elastic element is disposed between two partially adjacent track teeth.

[0007] In this technical solution, the traveling device includes a track frame, track section, drive unit, and elastic element. The track section is fitted onto the track frame, and the drive unit is mounted on the track frame and connected to the track section. Thus, the drive unit can drive the track section for transmission, achieving the effect of walking. Furthermore, the track section is provided with multiple track teeth, spaced apart on the track section, located on the side of the track section opposite to the track frame. These track teeth are used to abut against the ground where the traveling device is located. In practical applications, the track teeth... The track teeth penetrate the mountain below the traveling device, and the force between the track teeth and the mountain provides an anti-slip function, thus ensuring stable movement of the traveling device. In addition, the traveling device proposed in this application has elastic elements between some adjacent track teeth. Under the action of its own weight, the elastic elements are compressed and deformed, so that even when the mountain rock is hard, the elastic elements can make full contact with the mountain, increasing the friction between the traveling device and the mountain. This helps the track teeth to further improve the adhesion of the traveling device to the mountain and reduce the probability of the traveling device sliding down.

[0008] It should be noted that in related technologies, under conditions of steep downhill slopes and hard rock, the track teeth of the tunneling machine are difficult to penetrate the rock. This reduces the contact area between the track plates and the bottom plate, and the shear resistance between the track teeth and the rock surface alone is insufficient to provide adequate resistance, easily leading to the tunneling machine slipping and posing a safety hazard. In contrast to related technologies, the traveling device proposed in this application, by incorporating elastic elements between the track teeth, allows the traveling device to simultaneously contact the mountain surface using both the track teeth and the elastic elements under conditions of steep downhill slopes and hard rock. This increases the contact area between the traveling device and the rock, combining the shear resistance between the track teeth and the hard rock with the frictional force between the elastic elements and the hard rock, thus improving the traveling device's adhesion to the mountain and reducing the risk of slippage.

[0009] It is understandable that the traveling device can move on, but is not limited to, the surface of the mountain.

[0010] This technical solution provides a traveling device, which, in addition to the technical features of the above-mentioned technical solution, further includes the following technical features.

[0011] In some technical solutions of this application, the elastic element may optionally protrude from the track teeth.

[0012] In this technical solution, the elastic element protrudes beyond the track teeth. This design ensures that even when the track teeth cannot penetrate the mountain rock, the elastic element can still make full contact with the mountain rock and be squeezed. The contact area between the squeezed elastic element and the mountain rock will be further increased, thereby further improving the friction between the traveling device and the mountain and reducing the risk of the traveling device sliding down.

[0013] For example, the elastic element can be made of rubber, which is highly resistant to the environment and can adapt to a variety of complex working conditions. On the other hand, it can also absorb impact, reduce vibration and noise, which is conducive to the smooth movement of the traveling device.

[0014] In some technical solutions of this application, optionally, the track section includes: a plurality of first track plates, each first track plate having at least two track teeth; a plurality of second track plates, each second track plate having at least two track teeth; wherein, an elastic element is disposed on the second track plate, located between the track teeth, and each second track plate connects two first track plates.

[0015] In this technical solution, the track section includes multiple first track plates and multiple second track plates, and each first track plate and each second track plate is provided with at least two track teeth. Elastic elements are provided on the second track plates, while no elastic elements are provided on the first track plates. This allows the first track plates to maintain a form where there are no other arrangements between the track teeth, so that the track teeth of the first track plates can more easily penetrate the mountain surface with less hardness. At the same time, each second track plate is connected to two first track plates, allowing the second track plate to pass between the first track plates. Thus, along the direction of track drive of the traveling device, the elastic elements can be arranged at intervals on the track section. On the one hand, this saves material for the elastic elements, and on the other hand, it also helps each elastic element to be fully compressed and play an anti-slip role.

[0016] In some technical solutions of this application, the elastic element and the second track plate are optionally integrated into one structure.

[0017] In this technical solution, the elastic element and the second track plate are an integral structure, which can prevent the elastic element from falling off and improve the force transmission between the elastic element and the second track plate.

[0018] For example, the elastic element and the second track plate are formed into an integral structure through vulcanization.

[0019] For example, the elastic element and the second track plate are bonded and cured to form an integral structure.

[0020] In some technical solutions of this application, optionally, one side of the second track plate has two connectors and the other side of the second track plate has two lugs, and the second track plate is hinged to the first track plate through the connectors or lugs.

[0021] In this technical solution, the second track plate is hinged to the first track plate via connectors and lugs. The second track plate has two connectors on one side and two lugs on the other side. Similarly, the first track plate has two connectors on one side and two lugs on the other side. Thus, the connectors of the first track plate can be hinged to the lugs of the second track plate, and the lugs of the first track plate can be hinged to the connectors of the second track plate. This arrangement makes the track section both flexible and stable, and this connection method is also easier to install and disassemble.

[0022] For example, the connector of the first track plate and the lug of the second track plate, as well as the connector of the lug of the first track plate and the second track plate, can be hinged by a pivot bolt.

[0023] In some technical solutions of this application, optionally, the drive unit includes: a drive component and a reducer; the drive component is disposed on the track frame, the drive component is used to provide driving force, the input end of the reducer is connected to the drive component, and the output end of the reducer is connected to the track unit.

[0024] In this technical solution, the drive unit includes a drive component and a reducer. The drive component is connected to the track plate through the reducer. The drive component can provide driving force for the transmission of the track plate. The reducer reduces the speed of the drive component, thereby improving control accuracy and increasing the torque transmitted by the drive component. This allows the traveling device to maintain high-precision control and have greater power when moving, making it more suitable for adapting to various complex working conditions.

[0025] The second aspect of this application provides a tunneling machine, including a traveling device as described in any of the above technical solutions.

[0026] In this technical solution, since it has the traveling device of any of the above technical solutions, all the beneficial effects of the traveling device of any of the above technical solutions will not be elaborated here.

[0027] Optionally, in some technical solutions of this application, the tunneling machine may also include a body and a control panel. The body is located on the traveling device and has a control space. The control panel is located in the control space and is communicatively connected to the drive unit.

[0028] In this technical solution, the tunneling machine also includes a body and a control panel. The body is mounted on the traveling device, and the control panel is located within the control space of the body. The control panel is communicatively connected to the drive unit, thereby controlling the driving force provided by the drive unit. With this configuration, the operator can control the control panel within the control space, thus controlling the traveling device. The control space also provides a certain degree of protection for the operator.

[0029] For example, the tunneling machine also includes an electrical control box, through which the control panel controls the drive unit, support unit, etc.

[0030] Optionally, in some technical solutions of this application, the tunneling machine may further include: a support unit, which is movably disposed on the main body of the vehicle body, and the control panel is communicatively connected to the support unit; wherein, the support unit has an extended state and a retracted state; when the support unit is in the extended state, the support unit is used to abut against the work site; when the support unit is in the retracted state, the support unit retracts into the main body of the vehicle body.

[0031] In this technical solution, the tunneling machine also includes a support unit, which is movably mounted on the main body of the machine. The support unit has an extended state and a retracted state. The control panel is communicatively connected to the support unit, thereby controlling the switching between the extended and retracted states. When the support unit is in the extended state, it extends and can abut against the work site, such as the rock wall of a mountain, thus creating a certain resistance between the support unit and the mountain. This improves the stability of the tunneling machine when it stops moving. When the support unit is in the retracted state, it retracts into the main body of the machine, thereby preventing the support unit from interfering with the movement of the tunneling machine.

[0032] Understandably, the support can be placed against the ground of the mountain or against the side wall of the mountain.

[0033] Optionally, in some technical solutions of this application, the tunneling machine may further include: a cutting section and a shovel section. The cutting section is disposed on the main body of the vehicle body, and the extending direction of the cutting section is the same as the moving direction of the traveling device. The cutting section is communicatively connected to the control panel. The shovel section is movably disposed on the main body of the vehicle body, and the shovel section is located on the side of the main body of the vehicle body closer to the cutting section. The shovel section is communicatively connected to the control panel.

[0034] In this technical solution, the tunneling machine also includes a cutting section and a shovel section. The tunneling machine can use the cutting section to cut the roadway and use the shovel section to collect the cut material.

[0035] For example, the tunneling machine also includes a first conveyor, which is equipped with a scraper chain inside. A chute is provided in the middle of the shovel section. The first conveyor is configured to correspond to the chute. The shovel section collects the cut material into the chute in the middle. The chute is connected to the first conveyor, and the material is transported out of the tail end by the scraper chain inside the first conveyor.

[0036] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0039] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0041] The following reference Figures 1 to 3 The present application describes a traveling device 10 and a tunneling machine 1 according to some embodiments.

[0042] like Figure 1 and Figure 2 As shown, this application provides a traveling device 10, including a track frame 12, a track section 14, a drive section 16, and an elastic element 18; the track section 14 is sleeved on the track frame 12, and the track section 14 is provided with track teeth 142, with a plurality of track teeth 142 spaced apart on one side of the track section 14 away from the track frame 12; the drive section 16 is disposed on the track frame 12, and the drive section 16 is connected to the track section 14, and the drive section 16 is used to drive the track section 14 for transmission; the elastic element 18 is disposed between two partially adjacent track teeth 142.

[0043] In this embodiment, the traveling device 10 includes a track frame 12, a track section 14, a drive unit 16, and an elastic element 18. The track section 14 is fitted onto the track frame 12, and the drive unit 16 is mounted on the track frame 12 and connected to the track section 14. Thus, the drive unit 16 can drive the track section 14 for transmission, achieving the effect of walking. Furthermore, the track section 14 is provided with multiple track teeth 142, spaced apart on the track section 14, and located on the side of the track section 14 opposite to the track frame 12. The track teeth 142 are used to abut against the ground where the traveling device 10 is located. In actual application… In use, the track teeth 142 can penetrate the mountain below the traveling device 10, and the force between the track teeth 142 and the mountain can play an anti-slip role, so as to make the traveling device 10 move stably. In addition, the traveling device 10 proposed in this application has an elastic element 18 between some adjacent track teeth 142. Under the action of its own weight, the elastic element 18 will be squeezed and deformed, so that even if the mountain rock is hard, the elastic element 18 can make full contact with the mountain, increasing the friction between the traveling device 10 and the mountain, thereby assisting the track teeth 142 to further improve the adhesion of the traveling device 10 to the mountain and reduce the probability of the traveling device 10 sliding down.

[0044] It should be noted that in related technologies, under conditions of steep downhill slopes and hard rock, the track teeth 142 of the tunneling machine 1 are difficult to penetrate the rock. This reduces the contact area between the track plates and the bottom plate, and the shear resistance between the track teeth 142 and the rock surface alone is insufficient to provide adequate resistance, easily leading to the tunneling machine 1 sliding downhill, posing a safety hazard. Compared to related technologies, the traveling device 10 proposed in this application, by also providing elastic elements 18 between the track teeth 142, allows the traveling device 10 to simultaneously contact the mountain surface using both the track teeth 142 and the elastic elements 18 under conditions of steep downhill slopes and hard rock. This increases the contact area between the traveling device 10 and the rock, combining the shear resistance between the track teeth 142 and the hard rock with the frictional force between the elastic elements 18 and the hard rock, thereby improving the adhesion of the traveling device 10 to the mountain and reducing the risk of the traveling device 10 sliding downhill.

[0045] It is understood that the traveling device 10 can move on, but is not limited to, the surface of a mountain.

[0046] This embodiment provides a traveling device 10, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0047] like Figure 1 and Figure 2As shown, in some embodiments of this application, the elastic element 18 may optionally protrude from the track tooth 142.

[0048] In this embodiment, the elastic element 18 protrudes beyond the track teeth 142. This arrangement ensures that even if the track teeth 142 cannot penetrate the mountain rocks, the elastic element 18 can still make full contact with the mountain rocks and be squeezed. After being squeezed, the contact area between the elastic element 18 and the mountain rocks will be further increased, thereby further improving the friction between the traveling device 10 and the mountain and reducing the risk of the traveling device 10 sliding down.

[0049] For example, the elastic element 18 can be made of rubber, which is highly resistant to the environment and can adapt to a variety of complex working conditions. On the other hand, it can also absorb impact, reduce vibration and noise, which is conducive to the smooth movement of the traveling device 10.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments of this application, optionally, the track section 14 includes: a plurality of first track plates 144, each first track plate 144 having at least two track teeth 142; a plurality of second track plates 146, each second track plate 146 having at least two track teeth 142; wherein, an elastic member 18 is disposed on the second track plates 146, located between the track teeth 142, and each second track plate 146 connects two first track plates 144.

[0051] In this embodiment, the track section 14 includes a plurality of first track plates 144 and a plurality of second track plates 146, and each first track plate 144 and each second track plate 146 is provided with at least two track teeth 142. Elastic members 18 are provided on the second track plates 146, but no elastic members 18 are provided on the first track plates 144. This allows the first track plates 144 to maintain a form where there are no other arrangements between the track teeth 142, so that the track teeth 142 of the first track plates 144 can more easily penetrate the mountain surface where the traveling device 10 has low hardness. At the same time, each second track plate 146 is connected to two first track plates 144, allowing the second track plate 146 to pass between the first track plates 144. Thus, along the direction of track drive of the traveling device 10, the elastic members 18 can be arranged at intervals on the track section 14. On the one hand, this can save material of the elastic members 18, and on the other hand, it can also help each elastic member 18 to be fully compressed and play an anti-slip role.

[0052] In some embodiments of this application, the elastic element 18 and the second track plate 146 are optionally an integral structure.

[0053] In this embodiment, the elastic element 18 and the second track plate 146 are an integral structure, which can prevent the elastic element 18 from falling off and improve the force transmission between the elastic element 18 and the second track plate 146.

[0054] For example, the elastic element 18 and the second track plate 146 are formed into an integral structure through vulcanization.

[0055] For example, the elastic element 18 and the second track plate 146 are bonded together to form an integral structure.

[0056] like Figure 2 As shown, in some embodiments of this application, optionally, one side of the second track plate 146 has two connectors 1462, and the other side of the second track plate 146 has two lugs 1464. The second track plate 146 is hinged to the first track plate 144 through the connectors 1462 or the lugs 1464.

[0057] In this embodiment, the second track plate 146 and the first track plate 144 are hinged together by connectors 1462 and lugs 1464. The second track plate 146 has two connectors 1462 on one side and two lugs 1464 on the other side. The first track plate 144 also has two connectors 1462 on one side and two lugs 1464 on the other side. Thus, the connectors 1462 of the first track plate 144 can be hinged to the lugs 1464 of the second track plate 146, and the lugs 1464 of the first track plate 144 can be hinged to the connectors 1462 of the second track plate 146. This arrangement makes the track section 14 both flexible and stable, and this connection method is also easier to install and disassemble.

[0058] For example, the connector 1462 of the first track plate 144 and the lug 1464 of the second track plate 146, as well as the lug 1464 of the first track plate 144 and the connector 1462 of the second track plate 146, can be hinged by a pivot bolt.

[0059] like Figure 1 As shown, in some embodiments of this application, optionally, the drive unit 16 includes: a drive member 162 and a reducer 164; the drive member 162 is disposed on the track frame 12, the drive member 162 is used to provide driving force, the input end of the reducer 164 is connected to the drive member 162, and the output end of the reducer 164 is connected to the track unit 14.

[0060] In this embodiment, the drive unit 16 includes a drive member 162 and a reducer 164. The drive member 162 is connected to the track plate through the reducer 164. The drive member 162 can provide driving force for the transmission of the track plate. The reducer 164 reduces the rotational speed of the drive member 162, thereby improving control accuracy and increasing the torque transmitted by the drive member 162. This allows the traveling device 10 to maintain high-precision control and have greater power when moving, making it more suitable for adapting to various complex working conditions.

[0061] like Figure 3 As shown, a second aspect of this application provides a tunneling machine 1, including a traveling device 10 as described in any of the above embodiments.

[0062] In this embodiment, since it has the traveling device 10 of any of the above embodiments, it has all the beneficial effects of the traveling device 10 of any of the above embodiments, which will not be described in detail here.

[0063] like Figure 3 As shown, in some embodiments of this application, optionally, the tunneling machine 1 further includes a body 20 and a control console 30. The body 20 is disposed on the traveling device 10 and has a control space 22. The control console 30 is disposed in the control space 22. The control console 30 is communicatively connected to the drive unit 16.

[0064] In this embodiment, the tunneling machine 1 also includes a body 20 and a control panel 30. The body 20 is mounted on the traveling device 10, and the control panel 30 is located within the control space 22 of the body 20. The control panel 30 is communicatively connected to the drive unit 16, thereby controlling the driving force provided by the drive unit 16. With this configuration, the operator can control the control panel 30 within the control space 22, thus controlling the traveling device 10. The control space 22 also provides a certain degree of protection for the operator.

[0065] For example, the tunneling machine 1 also includes an electrical control box, through which the control panel 30 controls the drive unit 16, support unit 40, etc.

[0066] like Figure 3 As shown, in some embodiments of this application, optionally, the tunneling machine 1 further includes: a support part 40, the support part 40 being movably disposed on the vehicle body 20, and the control panel 30 being communicatively connected to the support part 40; The support part 40 has an extended state and a retracted state; when the support part 40 is in the extended state, the support part 40 is used to abut against the work site; when the support part 40 is in the retracted state, the support part 40 is retracted into the vehicle body 20.

[0067] In this embodiment, the tunneling machine 1 also includes a support part 40, which is movably mounted on the main body 20 of the machine. The support part 40 has an extended state and a retracted state. The control panel is communicatively connected to the support part 40, thereby controlling the switching between the extended and retracted states of the support part 40. When the support part 40 is in the extended state, it extends out and can abut against the working site, such as the rock wall of a mountain, thereby creating a certain resistance between the support part 40 and the mountain. This can improve the stability of the tunneling machine 1 when it stops moving. When the support part 40 is in the retracted state, it retracts into the main body 20 of the machine, thereby preventing the support part 40 from interfering with the movement of the tunneling machine 1.

[0068] Understandably, the support 40 can abut against the ground of the mountain or against the side wall of the mountain.

[0069] like Figure 3 As shown, in some embodiments of this application, the tunneling machine 1 may optionally include: a cutting section 50 and a shovel section 60. The cutting section 50 is disposed on the vehicle body 20, and the extending direction of the cutting section 50 is the same as the moving direction of the traveling device 10. The cutting section 50 is communicatively connected to the control panel 30. The shovel section 60 is movably disposed on the vehicle body 20, and the shovel section 60 is located on the side of the vehicle body 20 close to the cutting section 50. The shovel section 60 is communicatively connected to the control panel 30.

[0070] In this embodiment, the tunneling machine 1 also includes a cutting section 50 and a shovel section 60. The tunneling machine 1 can use the cutting section 50 to cut the roadway and use the shovel section 60 to collect the cut material.

[0071] For example, the tunneling machine 1 also includes a first conveyor 70, which is equipped with a scraper chain inside. The shovel section 60 is provided with a chute in the middle. The first conveyor 70 is provided with a corresponding chute. The shovel section 60 collects the cut material into the chute in the middle. The chute is connected to the first conveyor 70. The material is transported out of the tail end by the scraper chain inside the first conveyor 70.
