[0002] In the construction and development of projects such as tunnels, nuclear power plants, and mines, situations often arise where construction needs to be carried out within narrow, elongated ramps. These ramps are sloping structures with a unique spatial form, characterized by a length far exceeding their width, and typically featuring gentle slopes, a single path, and limited space. Due to the constraints of the narrow construction site space, conventional transportation equipment, such as overhead cranes and elevators, cannot access the site for material handling. When continuous material handling is required, it relies primarily on manual labor and simple tools. However, manual handling is inefficient, carries high risks, and impacts construction progress.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] like Figures 1 to 6 As shown, this embodiment provides a transfer platform for narrow ramps. The transfer platform includes a truss structure and a transfer mechanism. The truss structure includes an I-beam guide rail 1 and multiple suspension frames 2. The I-beam guide rail 1 includes multiple I-beam guide rail segments. The multiple suspension frames 2 are spaced apart in the ramp direction, with one I-beam guide rail segment suspended between every two adjacent suspension frames 2. The multiple I-beam guide rail segments are sequentially connected in the ramp direction to form the I-beam guide rail 1. The transfer mechanism includes a traction device 6, a traction rope 7, and a transport trolley 8. The traction device 6 is located at one end of the truss structure. The traction rope 7 forms a loop on the truss structure, and the traction device 6 can drive the traction rope 7 to reciprocate on the truss structure. The transport trolley 8 is slidably mounted on the I-beam guide rail 1 and can reciprocate along the traction rope 7 on the I-beam guide rail 1. The transport trolley 8 is used to suspend materials.

[0047] This utility model provides a transfer platform for narrow ramps. Based on the length of the ramp, the truss structure is designed as multiple independent modules consisting of I-beam guide rail segments and multiple suspension frames 2. When installing the truss structure within the ramp, only multiple suspension frames 2 need to be spaced apart along the ramp direction, with an I-beam guide rail segment suspended between every two adjacent suspension frames 2. These multiple I-beam guide rail segments are sequentially connected along the ramp direction to form an I-beam guide rail 1. A traction device 6 is installed at one end of the truss structure, and a traction rope 7 forms a loop on the truss structure. A transport trolley 8 is slidably mounted on the I-beam guide rail 1. When transporting materials, the materials are suspended on the transport trolley 8. The traction device 6 then drives the traction rope 7 to reciprocate along the truss structure, thereby causing the transport trolley 8 to move the materials back and forth along the I-beam guide rail 1, thus realizing the transport of materials within the ramp. Through the modular design of the truss structure and transfer mechanism, this transfer platform is easy to assemble and use, occupies little space, has a stable and reliable structure, is simple to install, and can meet the construction needs of narrow ramps.

[0048] Optionally, in this embodiment, the traction device 6 is a double-drum horizontal winch. The two drums of the double-drum horizontal winch can be controlled separately or operated in conjunction, which can reduce downtime caused by rope changing or reversing. It is especially suitable for long-distance traction or continuous hoisting scenarios. At the same time, the horizontal layout reduces the overall height of the equipment, making it suitable for scenarios with limited vertical space, such as tunnels, underground mines, and ship cabins. Of course, it is understood that in some other embodiments, the traction device 6 may also adopt other devices according to actual needs, such as a double-drum synchronous winch, a rail traction winch, etc., which are not limited here.

[0049] Optionally, in this embodiment, the traction rope 7 is a steel wire rope. Steel wire ropes have high tensile and compressive strength, are durable, and have low cost. Of course, it is understood that in some other embodiments, other types of ropes, such as aramid fiber ropes, may be used according to actual needs, and this is not a limitation.

[0050] like Figure 1 and Figure 2 As shown, the suspension frame 2 includes a suspension beam 22 and two columns 21. The two columns 21 are respectively set on both sides of the narrow ramp, and the suspension beam 22 is set between the two columns 21 and located above the slope of the narrow ramp. The I-beam guide rail 1 is installed on the lower side of the suspension beam 22. By setting the suspension beam 22 and the columns 21 into a portal frame structure and installing the I-beam guide rail 1 on the lower side of the suspension beam 22, not only can the space occupied by the suspension frame 2 and the I-beam guide rail 1 in the narrow ramp be saved, but the truss structure can also be easily dismantled after construction.

[0051] Furthermore, such as Figure 1 and Figure 2 As shown, a crossbeam 10 and a diagonal brace 11 are also provided at the unloading end of the truss structure. The crossbeam 10 is located between the columns 21 on the same side of two adjacent suspension frames 2 at the unloading end, and the diagonal brace 11 is located between the I-beam guide rail 1 at the unloading end and the column 21 of the adjacent suspension frame 2. By providing the crossbeam 10 and the diagonal brace 11, the structural strength of the truss structure at the unloading end can be further enhanced, and it also facilitates the unloading process for workers.

[0052] Optionally, such as Figure 2 As shown, the I-beam guide rail 1 has two first steering wheels 12 at one end near the traction device 6, and a second steering wheel 13 at the other end. One end of the traction rope 7 is connected to the output end of the traction device 6, and the other end passes sequentially around one of the first steering wheels 12, the second steering wheel 13, and the other first steering wheel 12 to connect to the input end of the traction device 6. This arrangement allows the traction rope 7 to form a loop on the truss structure, and the traction device 6 can retract and extend the traction rope 7 at both the input and output ends, thereby achieving the reciprocating motion of the traction rope 7 on the truss structure.

[0053] It is understood that in some other embodiments, other types of steering devices may also be used, such as providing steering grooves at both ends of the I-beam guide rail 1 and providing a lubricating layer that can reduce friction on the surface of the steering groove that contacts the traction rope 7, so that the traction rope 7 can travel around in the steering groove. This is not a limitation.

[0054] like Figure 2 and Figure 3 As shown, the transfer mechanism also includes multiple first sheaves 3 and multiple second sheaves 4. Each first sheave 3 is mounted on an I-beam guide rail 1, and each second sheave 4 is mounted on a suspension frame 2. The first sheaves 3 are used for the traction rope 7 located on the lower side of the suspension frame 2 to wind around, and the second sheaves 4 are used for the traction rope 7 located on the upper side of the suspension frame 2 to wind around. By setting the first sheaves 3 and the second sheaves 4 to support and guide the traction rope 7 between the first steering wheel 12 and the second steering wheel 13, the traction rope 7 can move more smoothly and stably on the truss structure.

[0055] like Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the first pulley 3 includes a first mounting member 31 and a first pulley 32. One end of the first mounting member 31 is mounted on the upper flange of the I-beam guide rail 1, and the other end faces the lower flange of the I-beam guide rail 1. The first pulley 32 is mounted on the end of the first mounting member 31 facing the lower flange. Specifically, the first mounting member 31 is roughly a triangular plate structure. One bottom edge of the triangular-shaped first mounting member 31 is mounted on the upper flange of the I-beam guide rail 1. The first pulley 32 is mounted at a diagonal position opposite to the bottom edge, and the first pulley 32 is located on the side of the first mounting member 31 away from the web of the I-beam guide rail 1. A first rotating shaft 33 is also provided on the first mounting member 31, and the first pulley 32 is rotatably mounted on the first rotating shaft 33.

[0056] It is understood that in some other embodiments, the specific structure of the first mounting member 31 can be designed according to actual needs and is not limited to a triangular plate structure; it is also understood that the first rope pulley 3 can be installed on the left side of the web plate of the I-beam guide rail 1 or on the right side of the web plate, without any limitation.

[0057] like Figure 3 , Figure 9 and Figure 10As shown, the second rope pulley 4 includes a second mounting member 41 and a second pulley 42. One end of the second mounting member 41 is mounted on the suspension frame 2, and the second pulley 42 is mounted on the other end of the second mounting member 41. Specifically, the second mounting member 41 is generally a U-shaped plate structure. The open end of the U-shaped plate is mounted on the suspension frame 2, and the second pulley 42 is mounted between the two side walls of the U-shaped plate. A second rotating shaft 43 is provided through the two side walls of the U-shaped plate, and the second pulley 42 is rotatably mounted on the second rotating shaft 43.

[0058] It is understood that in some other embodiments, the closed end of the U-shaped plate may also be mounted on the suspension bracket 2, and this is not a limitation. It is also understood that in some other embodiments, the specific structure of the second mounting member 41 can be designed according to actual needs and is not limited to a U-shaped plate structure.

[0059] Furthermore, such as Figure 3 As shown, a portion of the traction rope 7 winds around the upper side of the first pulley 32 and the second pulley 42, while another portion winds around the lower side of the first pulley 32 and the second pulley 42. By alternately winding the traction rope 7 around the upper and lower sides of the first pulley 32 and the second pulley 42, it can be ensured that the traction rope 7 is always located on the first pulley 32 and the second pulley 42. This avoids the situation where the traction rope 7 detaches from the first pulley 32 or the second pulley 42 when it only winds around the upper or lower side of the pulley, and further ensures the stability of the traction rope 7 during reciprocating motion on the truss structure.

[0060] like Figure 2 As shown, the transfer mechanism also includes an adjustment device 5, which is mounted on the I-beam guide rail 1. The traction rope 7 can travel around the adjustment device 5, and the adjustment device 5 is used to adjust the tension of the traction rope 7. By setting the adjustment device 5, the traction rope 7 on the truss structure can be tightened when it becomes loose, or the tension of the traction rope 7 can be adjusted when transporting materials of different weights, thereby achieving stable transportation of materials.

[0061] Optionally, such as Figure 11 and Figure 12As shown, in this embodiment, the adjusting device 5 includes a mounting frame 51 and a guide wheel 52. The mounting frame 51 is mounted on the I-beam guide rail 1, and the guide wheel 52 is rotatably mounted on the mounting frame 51. The position of the guide wheel 52 on the mounting frame 51 is adjustable, and the guide wheel 52 is used to guide the traction rope 7. Specifically, the mounting frame 51 includes two clamping plates, and a third rotating shaft 53 is provided through the two clamping plates. The guide wheel 52 is rotatably mounted on the third rotating shaft 53. Further, the two clamping plates are provided with multiple alignment through holes along their length, and the third rotating shaft 53 can be passed through each pair of alignment through holes. Thus, when the guide wheel 52 is positioned at different alignment through holes, the position of the guide wheel 52 on the clamping plates can be adjusted. When the traction rope 7 on the truss structure becomes loose, the guide wheel 52 on the mounting frame 51 can be adjusted to move away from the truss structure, thereby tightening the traction rope 7. Furthermore, the mounting bracket 51 also includes a support bracket 54, which is disposed on both sides of the clamping plate to assist the clamping plate in being stably mounted on the I-beam guide rail 1.

[0062] It is understood that in some other embodiments, the adjusting device 5 may also be other devices capable of tensioning the traction rope 7, such as a spiral tensioner, which adjusts the length of the traction rope 7 by rotating the threaded rod to achieve tension control, and is not limited here.

[0063] like Figure 2 , Figure 4 and Figure 5 As shown, the transport trolley 8 includes a frame 81, wheels 82, and a hook 83. The frame 81 is generally a U-shaped frame structure, with the open end of the U-shaped frame facing the I-beam guide rail 1. Wheels 82 are installed on both side walls of the U-shaped frame, and the wheels 82 are located between the side walls, so that when the transport trolley 8 is installed on the I-beam guide rail 1, the wheels 82 can roll on the lower flange of the I-beam guide rail 1. The hook 83 is located at the closed end of the U-shaped frame. The hook 83 is used to lift materials, allowing the materials to be suspended on the transport trolley 8. A connecting plate is also provided between the hook 83 and the frame 81 to ensure the connection strength between the hook 83 and the frame 81.

[0064] It is understood that in some other embodiments, the structure of the transport vehicle 8 can also be designed as other structures, such as an H-shaped frame structure, which is not limited here.

[0065] Optionally, in this embodiment, four wheels 82 are provided, with two wheels on each of the two side walls of the frame 81. This arrangement allows the transport trolley 8 to move more stably on the I-beam guide rail 1. It is understood that in some other embodiments, the number of wheels 82 can also be set according to actual needs, and is not limited here.

[0066] Furthermore, in this embodiment, the wheel 82 is a flanged roller. During the movement of the transport trolley 8, the flanges on the flanged rollers located on both sides of the I-beam guide rail 1 can restrict the wheel 82 to the I-beam guide rail 1, thereby preventing the wheel 82 from shifting left and right and causing one side to derail, and further ensuring the stable movement of the transport trolley 8 on the I-beam guide rail 1.

[0067] Furthermore, in this embodiment, the hook 83 is a hook with automatic lifting function. Thus, during loading and unloading, the materials can be lifted and lowered by the automatic lifting of the hook 83, thereby reducing the labor intensity of the workers.

[0068] like Figure 5 and Figure 6 As shown, the transport trolley 8 is also equipped with a cable gripper 9, which includes a connecting end and a clamping end. The connecting end is connected to the transport trolley 8, and the clamping end is used to clamp the traction rope 7. Specifically, the cable gripper 9 is located at the open end of the frame 81 and on the same side of the I-beam guide rail 1 as the first rope sheave 3, so that the clamping end of the cable gripper 9 can clamp the traction rope 7 that is wound around the first rope sheave 3. When the traction rope 7 reciprocates on the truss structure, it can drive the transport trolley 8 to reciprocate synchronously on the I-beam guide rail 1. It should be noted that the clamping end of the cable gripper 9 clamps the part of the traction rope 7 that is not in contact with the first rope sheave 3, so it will not affect the sliding of the traction rope 7 on the first rope sheave 3.

[0069] Optionally, in this embodiment, two grippers 9 are provided to ensure a stable connection between the transport trolley 8 and the traction rope 7. It is understood that in some other embodiments, the number of grippers 9 can be set according to actual needs and is not limited here.

[0070] Furthermore, such as Figure 6 As shown, the connecting end of the cable gripper 9 is hinged to the transport trolley 8. The hinge allows the cable gripper 9 to float up and down within a certain range, enabling the transport trolley 8 to smoothly pass through the turns of the uphill and downhill sections, ensuring the stable transportation of materials.

[0071] The specific working process of the transfer platform for narrow ramps provided in this embodiment is as follows:

[0072] When transporting materials, the materials are first hoisted onto the transport trolley 8, and then the traction device 6 is turned on. The traction device 6 drives the traction rope 7 to reciprocate on the truss structure, which in turn drives the transport trolley 8 to reciprocate on the I-beam guide rail 1, thereby realizing the transport of materials between the loading end and the unloading end of the transfer platform.

[0073] The transfer platform for narrow ramps provided by this utility model, through the modular design of the truss structure and transfer mechanism, makes the transfer platform easy to assemble and use, occupies little space, has a stable and reliable structure, is simple to install, and can meet the construction needs in narrow ramps.

[0074] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
