Description

Technical Field

[0001] This utility model belongs to the field of tunnel excavation technology, specifically relating to a replaceable track structure for an auxiliary device of a tunnel steel reinforcement trolley. Background Technology

[0002] The steel rebar trolleys used in tunnel construction are often equipped with rails on which the loads are mounted, allowing them to slide along the rails and be used in different locations. Common loads include steel rebar sleeve extrusion machines and sliding hooks (used for transporting goods). However, in the traditional way, each load requires an independent rail to be used. If two loads share a rail, interference will occur when the two loads move towards each other. Of course, setting an independent rail for each load not only takes up space but also increases the weight of the trolley. Utility Model Content

[0003] To address the problems mentioned in the background section, this invention provides a detachable track structure for an auxiliary device for a tunnel rebar trolley. The traditional track is replaced with an I-shaped suspended rail, where both the upper and lower flanges allow for the movement of the load. By rotating the rail, the downward-facing load can slide freely.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a replaceable track structure for an auxiliary equipment for a tunnel steel reinforcement trolley, comprising an I-shaped suspension rail rotatably connected to the frame;

[0005] One end of the frame is fixedly connected to a central shaft via an axle bracket. A rotating sleeve is rotatably connected to the outer side of the central shaft. A connecting plate is fixedly connected to the plane of the rotating sleeve via a connecting sleeve. The plane of the connecting plate is fixedly connected to the end of the overhead rail. One end of the rotating sleeve is rotatably connected to one end of a hook-shaped rod. The other end of the hook-shaped rod is rotatably connected to one end of a hydraulic cylinder A. The other end of the hydraulic cylinder A is rotatably connected relative to the frame.

[0006] As a preferred alternative track structure for the auxiliary equipment of the tunnel steel reinforcement trolley structure of this utility model, the rotating sleeve can rotate within the range of 0-180 degrees.

[0007] As a preferred alternative track structure for the auxiliary equipment of the tunnel rebar trolley structure of this utility model, the other end of the hook-shaped rod is provided with a flat part. Before the rotating sleeve rotates, the flat part of the hook-shaped rod is used to contact the blocking plane A. After the rotating sleeve rotates, the flat part of the hook-shaped rod is used to contact the blocking plane B.

[0008] As a preferred alternative to the detachable track structure of the tunnel steel reinforcement trolley structure of this utility model, several hanging rails are arranged linearly, and a through hole is opened between two adjacent hanging rails for the screw to pass through. The connecting parts are fixedly connected to the hanging rails by screws and nuts.

[0009] As a preferred alternative track structure for the auxiliary equipment of the tunnel steel reinforcement trolley structure of this utility model, the middle part of the connector is provided with an annular groove that rotates with the hook-shaped part of the hook-shaped rod, and the distance between two adjacent suspension rails is not less than the diameter of the hook-shaped rod.

[0010] As a preferred alternative track structure for the auxiliary equipment of the tunnel steel reinforcement trolley structure of this utility model, the top end of the hook-shaped lifting rod is fixedly connected to the lifting frame through a hydraulic rod connecting frame, and the lifting frame is fixedly connected to one end of the frame through bracket B.

[0011] As a preferred alternative track structure for the auxiliary equipment of the tunnel steel reinforcement trolley structure of this utility model, a hydraulic cylinder B is fixedly connected to the inner side of the hydraulic rod connecting frame. The hydraulic cylinder B is a double-shaft hydraulic cylinder. A slider joint is fixedly connected to the end of the telescopic main shaft of the hydraulic cylinder B. The sliding fit part of the slider joint is slidably fitted with the rotating part. A clamp is rotatably connected to one end of the rotating part. One end of the clamp is rotatably connected to the rotating bracket. The rotating bracket is fixedly connected to the hanger. The clamp is used to clamp and lock two adjacent hanging rails.

[0012] Compared with existing technologies, the beneficial effects of this utility model are: The traditional track is replaced with an I-shaped suspension rail. Both the upper and lower flanges of the suspension rail allow for the movement of the load. By flipping the suspension rail, downward-facing loads can slide freely, while upward-facing loads can only move within a limited range. Upward-facing loads can be temporarily unused or used only within a limited area. For example, a rebar sleeve extrusion machine, after being flipped upwards, can only be used within a limited range. The rebar sleeve extrusion machine is fixedly connected to a sliding platform via ropes. For example, load A can be represented as a rebar sleeve. The extruder, with its mounting B represented as a sliding hook, rotates the suspension rail via the extension and retraction of hydraulic cylinder A. Hydraulic cylinder A drives the hook-shaped rod to move, and the movement of one end of the hook-shaped rod causes the rotating sleeve to rotate around the central axis. The rotation of the rotating sleeve causes the connecting sleeve to rotate, which in turn causes the connecting disc to rotate. The rotation of the connecting disc then causes the suspension rail to rotate, thus achieving the rotation of the suspension rail. Compared to traditional motor drives and rotating cylinders, which are bulky and incompatible with the trolley structure, this solution features a simple structure, small size, low failure rate, and flexible rotation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-10 As shown:

[0028] A replaceable track structure for an auxiliary equipment for a tunnel steel reinforcement trolley includes an I-shaped hanging rail 2 that is rotatably connected to the frame 1.

[0029] One end of the frame 1 is fixedly connected to a central shaft 6 via a shaft bracket 7. A rotating sleeve 5 is rotatably connected to the outer side of the central shaft 6. A connecting plate 9 is fixedly connected to the plane of the rotating sleeve 5 via a connecting sleeve 8. The plane of the connecting plate 9 is fixedly connected to the end of the hanging rail 2. The inner side of one end of the rotating sleeve 5 is rotatably connected to one end of the hook rod 10. The other end of the hook rod 10 is rotatably connected to one end of the hydraulic cylinder A11. The other end of the hydraulic cylinder A11 is rotatably connected relative to the frame 1.

[0030] The steel rebar trolleys used in tunnel construction are often equipped with rails on which the loads are hung, allowing them to slide along the rails and be used in different positions. Common loads include steel rebar sleeve extrusion machines and sliding hooks (used for transporting goods). However, in the traditional way, each load needs to be used with an independent rail. If two loads share a rail, they will interfere when they move towards each other. Of course, setting an independent rail for each load not only takes up space but also increases the weight of the trolley.

[0031] The traditional track is replaced with an I-shaped lifting rail 2. Both the upper and lower flanges of the lifting rail 2 allow for the movement of the suspended load. By flipping the lifting rail 2, downward-facing loads can slide freely, while upward-facing loads can only move within a limited area. Upward-facing loads can be temporarily unused or used only within a limited area. For example, a rebar sleeve extrusion machine, after being flipped upwards, can only be used within a limited area. The rebar sleeve extrusion machine is fixedly connected to a sliding platform via ropes. For example, load A3 can be represented as the rebar sleeve extrusion machine, and load B4 can be represented as a sliding hook. When rotating the hanging rail 2, it is achieved by the extension and retraction of the hydraulic cylinder A11. The hydraulic cylinder A11 drives the hook rod 10 to move. The movement of one end of the hook rod 10 will drive the rotating sleeve 5 to rotate around the central axis 6. The rotation of the rotating sleeve 5 will drive the connecting sleeve 8, which in turn drives the connecting plate 9 to rotate. The rotation of the connecting plate 9 will drive the hanging rail 2 to rotate, thus realizing the flipping of the hanging rail 2. Compared with the traditional motor drive and rotating cylinder used to drive the rotation of the hanging rail 2, the motor drive and rotating cylinder are large in size and their shape is not compatible with the trolley structure. However, the structure of this solution is simple, small in size, has a low failure rate, and is flexible in flipping.

[0032] In an optional embodiment, the rotating sleeve 5 is capable of rotating within a range of 0-180 degrees.

[0033] In this embodiment, for the I-shaped hanging rail 2, it is best if the planes of the upper and lower flanges are both horizontal before and after flipping.

[0034] In an optional embodiment, the other end of the hook rod 10 is provided with a flat portion 12. Before the rotating sleeve 5 rotates, the flat portion 12 of the hook rod 10 is used to contact the blocking plane A13. After the rotating sleeve 5 rotates, the flat portion 12 of the hook rod 10 is used to contact the blocking plane B14.

[0035] In this embodiment, as Figure 6 and Figure 7As shown, the rotation center of the hook rod 10 and the rotating sleeve 5 coincides with the extension line of the flat part 12. When the hydraulic cylinder A11 extends, it drives the hook rod 10 to move until the flat part 12 of the hook rod 10 moves to be in contact with the blocking plane A13. Due to the influence of the plane blocking, the flat part 12 is forced to be perpendicular, thereby realizing that the rotation center of the rotating sleeve 5 and the hook rod 10 is located at the lowest position. Similarly, when the hydraulic cylinder A11 retracts, it drives the flat part 12 to be in contact with the blocking plane B14. When the surfaces are in contact, the plane is blocked, which forces the plane part 12 to be horizontal. At this time, the rotation center of the rotating sleeve 5 and the hook rod 10 is located at the uppermost position, so that the rotating sleeve 5 can rotate exactly 180 degrees each time. The blocking plane A13 and the blocking plane B14 are fixedly connected to the frame 1 through the bracket A15. Therefore, the hydraulic cylinder A11 can be a type with a built-in limit switch or pressure switch, or the hydraulic cylinder A11 can be selected with a stroke that matches the required movement stroke of this structure.

[0036] In one optional embodiment, several hanging rails 2 are arranged linearly, and a through hole is provided between two adjacent hanging rails 2 for the screw to pass through. The connector 17 is fixedly connected to the hanging rail 2 by the screw and nut.

[0037] In this embodiment, when a complete hanging rail 2 connects the two ends of the frame 1, its structural strength is insufficient because the hanging rail 2 is too long and has no support in the middle. In addition, there are few I-shaped hanging rails 2 on the market that can directly connect the two ends of the frame 1. They are costly and inconvenient to transport. Therefore, relatively short hanging rails 2 are usually purchased in combination. Through holes are opened between two adjacent hanging rails 2, and the connecting piece 17 is used to cooperate with the screw and nut for initial fixation.

[0038] In an optional embodiment, the middle part of the connector 17 is provided with an annular groove that rotatably engages with the hook-shaped part of the hook-shaped rod 16, and the distance between two adjacent suspension rails 2 is not less than the diameter of the hook-shaped rod 16.

[0039] In this embodiment, the connector 17 is suspended by the hook-shaped rod 16, thereby fixing the connection between the two suspension rails 2 relative to the frame 1 and preventing it from falling. At the same time, when the suspension rail 2 rotates, the suspension rail 2 drives the connector 17 to rotate, thereby driving the other suspension rail 2 to rotate. Since the connector 17 has an annular groove in the middle that rotates with the hook-shaped part of the hook-shaped rod 16, the connector 17 can rotate relative to the hook-shaped rod 16.

[0040] In an optional embodiment, the top end of the hook-shaped boom 16 is fixedly connected to the hanger 19 via a hydraulic rod connector 18, and the hanger 19 is fixedly connected to one end of the frame 1 via a bracket B20.

[0041] In an optional embodiment, a hydraulic cylinder B21 is fixedly connected to the inner side of the hydraulic rod connecting frame 18. The hydraulic cylinder B21 is a dual-axis hydraulic cylinder. A slider joint 25 is fixedly connected to the end of the telescopic main shaft of the hydraulic cylinder B21. The sliding engagement part of the slider joint 25 is slidably engaged with the rotating part 22. One end of the rotating part 22 is rotatably connected to a clamp 23. One end of the clamp 23 is rotatably connected to a rotating bracket 24. The rotating bracket 24 is fixedly connected to the hanger 19. The clamp 23 is used to clamp and engage two adjacent hanging rails 2.

[0042] In this embodiment, the hook-shaped rod 16 alone is insufficient to achieve sufficient stability at the junction of the two hanging rails 2. The hook-shaped rod 16 and the connector 17 are mainly used to maintain the suspension state when the hanging rail 2 is flipped. The stability after the flip is completed mainly depends on the two clamps 23 clamping the junction of the two adjacent hanging rails 2. By retracting the hydraulic cylinder B21, the clamps 23 can be flipped and opened around the rotation axis of the rotating bracket 24, thereby releasing the clamping restriction on the hanging rail 2. In this process, the rotating component 22 will slide relative to the slider joint 25 for displacement compensation. After the displacement is completed, the hanging rail 2 can be flipped. After the flip is completed, the extension of the hydraulic cylinder B21 drives the clamps 23 to rotate back to the original position, thereby clamping and fixing the hanging rail 2 again.

[0043] It should be noted that when flipping the lifting rail 2, the loads A3 and B4 should be staggered from the hanger 19 to avoid interference between the loads A3 and B4 and the hanger 19 when flipping the lifting rail 2.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
