Description

Technical Field

[0001] This application relates to the field of tunnel boring machine transportation technology, and in particular to a transportation mechanism for hoisting anchor bolt trolleys. Background Technology

[0002] During tunnel excavation, tunnel boring machines (TBMs) are typically used. However, when the excavation length is large, tunnel collapse can occur, severely impacting project progress and worker safety. Therefore, anchor bolts are laid within the tunnel walls to provide support and stability. However, due to the large size of both the TBM and the anchor bolt trolley, they cannot operate simultaneously in ordinary tunnels. Currently, to ensure the anchor bolt trolley reaches the work site, it is usually driven into the tunnel after the TBM has left, which undoubtedly increases the time cost of tunnel excavation.

[0003] Generally, the soil at the bottom of the tunnel after excavation by a tunneling machine is relatively loose and contains many water-filled puddles. Allowing the bolting trolley to travel directly through these puddles would not only severely impact its speed but could also cause it to get stuck or overturn, negatively affecting personnel safety and tunnel construction. Therefore, there is an urgent need for a transportation mechanism that can ensure the bolting trolley can reach the work site safely and quickly. Utility Model Content

[0004] One objective of this application is to provide a transport mechanism for hoisting anchor bolt trolleys that can overcome at least one of the deficiencies in the aforementioned background art.

[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a transportation mechanism for hoisting anchor bolt trolleys, comprising a track installed above a roadway and the anchor bolt trolley, wherein at least one lifting device and at least one drive trolley are slidably mounted on the track; a drive device for controlling the lifting device and the drive trolley is provided on the track, the anchor bolt trolley is provided with a lifting point, and the lifting device is used to cooperate with the lifting point to lift the anchor bolt trolley; the drive trolley is used to drive the anchor bolt trolley to move along the track direction.

[0006] With the above setup, the drive unit can provide power to the lifting device and the drive trolley. The lifting device lifts the anchor bolt trolley and passes it over the water pit below. The drive trolley can then move the anchor bolt trolley on the track and pass it over the tunneling machine in the roadway. After the passing is completed and the anchor bolt trolley approaches the predetermined work position, the lifting device lowers the anchor bolt trolley to the ground for construction.

[0007] Preferably, the drive device is a hydraulic control box, which is connected to the power unit of the anchor bolt trolley. This configuration allows the hydraulic control box to be powered by the power unit of the anchor bolt trolley.

[0008] Preferably, the drive device is an external mining power system. This configuration further improves the versatility of the lifting device. When it is necessary to transport materials or non-anchor trolley type machinery, the external mining power system can maintain the normal operation of the lifting device and the drive trolley.

[0009] Preferably, the lifting device is a hydraulic winch, which includes a winch and a hook. The winch and the hook are connected by a chain. The winch controls the raising and lowering of the hook, and the hook works in conjunction with the lifting point to lift the anchor bolt trolley. With this configuration, when the anchor bolt trolley needs to be repositioned, the hook can be used to hook onto the lifting point, and then the winch can be used to control the cable to move upwards, thereby raising the anchor bolt trolley.

[0010] Preferably, a housing is installed between the winch and the hook, the housing being parallel to the track, the chain portion being located inside the housing, and the hook being perpendicular to the housing. This arrangement protects the chain through the housing, ensuring the hook is directly above the lifting point for vertical lifting of the anchor trolley.

[0011] Preferably, a connector is installed between the hook and the lifting point. This arrangement allows the hook and lifting point to be connected via the connector, preventing wear on the hook and lifting point structures and further extending their service life.

[0012] Preferably, a hook is rotatably mounted on the hook, the hook being used to close the opening of the hook. This arrangement ensures that the connecting parts will not detach from the hook during lifting, further improving the safety and stability of the lifting process.

[0013] Preferably, the anchor bolt trolley is equipped with a front shovel and a rear outrigger. The front shovel is rotatably mounted on the front of the anchor bolt trolley, and the rear outrigger is telescopically mounted on the rear of the anchor bolt trolley. This configuration allows the anchor bolt trolley to be lifted by the front shovel and / or the rear outrigger, preventing the trolley from sinking directly into the mud and becoming immobile.

[0014] Preferably, a retractable track is installed between the front shovel and the rear outriggers. The track is used for lateral fine-tuning of the position of the anchor bolt trolley. With this configuration, when the construction point deviates, one side of the track can be extended outward and the other side retracted inward. By repeating this process, the position of the anchor bolt trolley can be fine-tuned in a manner similar to walking.

[0015] Preferably, the anchor bolt trolley is equipped with a remote control component, which is simultaneously connected to the front shovel, the rear outriggers, and the tracks. This configuration eliminates the need for construction personnel to disembark for adjustments; fine-tuning of the anchor bolt trolley can be achieved solely through the onboard remote control component.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] The hook can work with the boom on the anchor bolt trolley to lift the anchor bolt trolley, preventing it from getting stuck in the mud pit below. The drive trolley can move the anchor bolt trolley on the track and pass it over the tunneling machine in the tunnel. Once the passing is completed and the anchor bolt trolley is close to the predetermined work position, the lifting device will lower the anchor bolt trolley to the ground for construction, thus ensuring that the anchor bolt trolley can quickly reach the work point.

[0018] Both the front shovel and the rear outriggers provide support. When the position of the anchor bolt trolley needs fine-tuning, the front shovel and rear outriggers are used to lift the trolley and extend its tracks. The tracks allow for precise adjustment of the trolley's position until the anchor bolting operation is complete. Furthermore, the retractable track design further reduces the overall width of the anchor bolt trolley when lifted, making it easier for the trolley to pass over the tunneling machine. This invention can quickly deliver the anchor bolt trolley to the designated location and offers advantages such as simple operation and high safety. Attached Figure Description

[0027] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0029] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0030] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0031] One aspect of this application provides a transport mechanism for lifting the anchor bolt trolley 1, such as... Figure 1 , Figure 2 and Figure 3 As shown, one preferred embodiment includes a track 100 and an anchor bolt trolley 1 installed above the tunnel. At least one lifting device 2 and at least one drive trolley 3 are slidably mounted on the track 100, wherein the lifting device 2 and the drive trolley 3 are interconnected to ensure that the drive trolley 3 can move the lifting device 2 on the track 100. The anchor bolt trolley 1 is provided with lifting points 200, which the lifting device 2 can use to lift the anchor bolt trolley 1, preventing the anchor bolt trolley 1 from being trapped in the mud pit below. In addition, to provide power to the drive trolley 3 and the lifting device 2, a drive device 4 is also provided on the track 100 to ensure that the anchor bolt trolley 1 can move along the track 100 according to the wishes of the construction personnel.

[0032] Understandably, once the anchor bolt trolley 1 is lifted, there is no need to consider ground factors. On the one hand, this can prevent the anchor bolt trolley 1 from getting stuck in the mud pit and affecting the construction progress. On the other hand, it can more quickly pass the excavating machine (tunneling machine) in the tunnel. After the passing is completed and the anchor bolt trolley 1 approaches the predetermined work position, the lifting device 2 lowers the anchor bolt trolley 1 to the ground for construction.

[0033] In this application, the drive device 4 is configured in ways including but not limited to the following two.

[0034] Configuration Method 1: The drive unit 4 is a hydraulic control box, which is connected to the power unit of the anchor bolt trolley 1. The power unit of the anchor bolt trolley 1 provides power to the hydraulic control box. The start / stop and movement direction of the anchor bolt trolley 1 on the track 100 can be controlled by the driver of the anchor bolt trolley 1.

[0035] Option 2: The drive device 4 is an external mining drive power system. The lifting device 2 and the drive trolley 3 do not need to rely on the power of the anchor bolt trolley 1, which can further improve the versatility of the lifting device 2. When it is necessary to transport materials or non-anchor bolt trolley 1 type machines, the normal operation of the lifting device 2 and the drive trolley 3 can be maintained through the external mining drive power system.

[0036] It should be noted that both of the above settings can meet the requirements of this application, and those skilled in the art can choose for themselves.

[0037] In this embodiment, as Figure 1 and Figure 2 As shown, the lifting device 2 is a hydraulic winch, and there are two hydraulic winches. Lifting points 200 are distributed at the front and rear ends of the anchor bolt trolley 1 to facilitate simultaneous lifting of the anchor bolt trolley 1 from both ends. The hydraulic winch includes a winch 21 and a hook 22, which are connected by a chain 23, allowing the winch 21 to control the lifting of the hook 22. The hook 22 is used to cooperate with the lifting points 200 to lift the anchor bolt trolley 1. When the anchor bolt trolley 1 needs to be moved, the hook 22 can be fixedly connected to the lifting points 200, and then the winch 21 can be used to control the cable to move upwards, thereby raising the anchor bolt trolley 1.

[0038] Specifically, such as Figure 2 As shown, a housing 24 parallel to the track 100 is installed between the winch 21 and the hook 22. A portion of the chain 23 is located inside the housing 24 to prevent it from rusting due to prolonged exposure to a humid environment. The portion of the chain 23 extending out of the housing 24 is perpendicular to the housing 24, ensuring that the hook 22 is directly above the lifting point 200, applying a vertically upward force to the lifting point 200, thereby vertically lifting the anchor trolley 1.

[0039] It should be understood that if the hook 22 is directly connected to the lifting point 200, long-term use may cause wear and tear on the lifting point 200 and the hook 22, increasing the maintenance cost of the mechanism; in addition, it will increase the length of the chain 23, which in turn will increase the volume of the housing 24, making the already cramped space even smaller, thereby reducing the height that the anchor trolley 1 can be lifted.

[0040] To address the aforementioned problems, in some embodiments of this application, such as Figure 2 and Figure 3 As shown, a connector 300 is installed between the hook 22 and the lifting point 200. One end of the connector 300 is connected to the hook 22, and the other end is connected to the lifting point 200. In this way, the hook 22 and the lifting point 200 can be connected through the connector 300, avoiding wear on the structure of the hook 22 and the lifting point 200, and further improving the service life of the hook 22 and the lifting point 200.

[0041] It should be noted that the connector 300 should have properties such as anti-slip and wear-resistant properties, and high tensile strength, and the hardness of the connector 300 should not be greater than that of the hook 22 and the lifting point 200. In this application, the preferred connector 300 is a lifting rope.

[0042] Furthermore, such as Figure 2 As shown, in order to prevent the lifting rope from coming off the hook 22 during operation, a hook 220 is rotatably installed on the hook 22 to close the opening of the hook 22. When the rope is connected to the hook 220, the movable end of the hook 220 can be abutted against the opening of the hook 22 to ensure that the connector 300 will not come off the hook 22 during the lifting process, thereby further improving the safety and stability of the lifting.

[0043] In this embodiment, as Figure 1 and Figure 3 As shown, the anchor bolt trolley 1 is equipped with a front shovel 11 and a rear outrigger 12. The front shovel 11 is rotatably mounted on the front of the anchor bolt trolley 1 to facilitate the removal of obstacles in front. The rear outrigger 12 is telescopically mounted on the rear of the anchor bolt trolley 1 to lift the vehicle body. When the anchor bolt trolley 1 is located in a tunnel, the vehicle body of the anchor bolt trolley 1 can be lifted by rotating the front shovel 11 and / or telescopically extending the rear outrigger 12, preventing the vehicle body from sinking directly into the mud and becoming immobile.

[0044] It should be noted that, in order to pass the tunneling machine in the tunnel, the track 100 is usually installed on the side of the tunnel. As a result, it is not possible to accurately transport the anchor bolt trolley 1 directly to the optimal working point. Therefore, in most cases, the anchor bolt trolley 1 is lowered to a place close to the working point, and then the anchor bolt trolley 1 is finely adjusted in position by itself. However, due to the large number of mud pits and the narrow space in the tunnel, the anchor bolt trolley 1 cannot be quickly adjusted to the correct position, which may delay the project.

[0045] In some embodiments of this application, such as Figure 1 , Figure 4 and Figure 5 As shown, a retractable track 13 is installed between the front shovel 11 and the rear outrigger 12. The track 13 is used for lateral fine-tuning of the position of the anchor bolt trolley 1. When there is a deviation in the construction point, one side of the track 13 can be extended outward and the other side can be retracted inward. By repeating this process, the position of the anchor bolt trolley 1 can be fine-tuned in a manner similar to walking, thereby avoiding the need for the anchor bolt trolley 1 to repeatedly turn to reach the optimal working point.

[0046] Furthermore, such as Figure 6 and Figure 7 In addition to fine-tuning the position of the bolting trolley 1, the telescopic function of the track 13 can also effectively reduce the lateral dimension of the bolting trolley 1. When the bolting trolley 1 is lifted, the tracks 13 on both sides retract inward to ensure that there is more space when passing the tunneling machine and to avoid collisions.

[0047] In addition, to further simplify the operation steps for construction personnel, the anchor bolt trolley 1 is equipped with a remote control component, which is simultaneously connected to the front shovel 11, the rear outriggers 12, and the tracks 13. When fine-tuning of the position of the anchor bolt trolley 1 is required, construction personnel do not need to disembark for adjustment; it can be achieved solely through the onboard remote control component. The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made without departing from the spirit and scope of this application, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
