Description

Technical Field

[0001] This utility model relates to the technical field of cable crane systems, and more specifically, to a small cable crane system for hoisting in rugged mountain valleys. Background Technology

[0002] In small-scale hoisting operations in complex terrains such as mountain valleys and canyons, traditional hoisting equipment often uses a crude structure with single cable support and simple pulley combinations. It lacks precise positioning and low-friction sliding design for high-altitude operations in canyons. When the load is uneven, there is wind disturbance, or the cable is deformed, it is easy to derail or get stuck, making it difficult to ensure the safety of the hoisting process. The support fixing system continues the traditional idea of ​​single-point rigid anchoring, relying on a single support point to bear the load. It has not formed a multi-directional connection and flexible load sharing mechanism. When geological conditions change in mountainous areas, such as rock weathering and slope settlement, stress concentration can easily cause the support to tilt or even collapse.

[0003] The existing publication number CN221988015U discloses a cable hoisting device, including cable towers, with cable towers set on both sides of a canyon; multiple cable hoisting mechanisms are spaced apart on the cable towers, each cable hoisting mechanism including two saddles, which are respectively set on the two cable towers, and several load-bearing cables are set between the two saddles; two trolleys are slidably mounted on the several load-bearing cables, and the two ends of a first connecting rod are respectively hinged to the two trolleys; the ends of the two trolleys that are far apart from each other are each connected to a first winch after passing around the corresponding cable saddle with a traction rope; a lifting seat is connected to the bottom of the trolleys through a pulley block, and a hook is set at the bottom of the lifting seat; one end of the lifting rope on one pulley block is connected to one end of the lifting rope on the other pulley block, and the ends of the two lifting ropes that are far apart from each other are wound around the corresponding cable saddles and are each connected to a second winch; this device solves the problems of existing cable hoists, which usually have a single hook, such as limited lifting capacity, low efficiency, and unstable structure that is prone to swaying during the hoisting process. The inventors discovered the following problems with the existing technology in the process of realizing this utility model:

[0004] Traditional cableless hoisting equipment relies on simple pulleys or single cables for support when the main structure moves. The traction wheel is prone to derailment or jamming due to load skewing or environmental disturbances, resulting in high sliding resistance and poor operational stability. Furthermore, existing hoisting equipment without rigid anchors cannot evenly distribute the force of the support structure to the rock mass through flexible chains. It is prone to tilting or collapse due to stress concentration in the terrain, making it difficult to adapt to the complex geological conditions of mountainous canyons.

[0005] Therefore, a small-scale cable crane system for hoisting in rugged mountain valleys is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a small-scale cable crane system for lifting in difficult mountain valleys, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a small cable crane system for lifting in rugged mountain valleys, comprising a main body, a support mechanism, and a traction component. The traction component is disposed below the support mechanism, and the main body is mounted on the side of the support mechanism. The main body includes a sliding component, a connecting component, and a cable component. The cable component is mounted on the outer diameter surface of the sliding component, and a connecting component is mounted below the sliding component. The support mechanism includes a fixing component, a supporting component, and a reversing component. The supporting component is mounted on the side of the fixing component, and a reversing component is mounted on the side of the fixing component away from the supporting component.

[0008] Preferably, the traction assembly includes a winch, a traction cable, and a traction block, wherein the traction cable is mounted on the outer diameter surface of the winch, and the traction block is mounted on the side of the traction cable.

[0009] Preferably, the sliding assembly includes a traction wheel, a rotating shaft, and a limiting groove block, wherein the rotating shaft is mounted on the inner diameter surface of the traction wheel, the limiting groove block is mounted on the side of the rotating shaft, and the traction wheel and the rotating shaft are connected by a bearing.

[0010] Preferably, the connecting assembly includes a connecting plate, a first fixing block, and a first fixing shaft, with the first fixing block installed below the connecting plate and the first fixing shaft installed on the side of the first fixing block.

[0011] Preferably, the cable assembly includes a first fixing cable, a second fixing cable, and a limiting ring, and the second fixing cable is provided on the side of the first fixing cable, and the limiting ring is installed on the side of the second fixing cable away from the first fixing cable.

[0012] Preferably, the fixing component includes a first fixing ring, a second fixing block, and a chain, wherein the second fixing block is installed below the first fixing ring, and the chain is installed on the side of the first fixing ring.

[0013] Preferably, the support assembly includes a support foot, a connecting column, and a bracket body, with the connecting column mounted above the support foot and the bracket body mounted above the connecting column.

[0014] Preferably, the reversing assembly includes a fixed pulley, a second fixed shaft, and a third fixed block, wherein the second fixed shaft is mounted on the inner diameter surface of the fixed pulley, the fixed pulley and the second fixed shaft are connected by a bearing, and the third fixed block is mounted on the side of the second fixed shaft.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with the prior art, this small cable crane system for lifting in difficult mountain valleys achieves efficient and stable sliding guidance through the limiting structure of the sliding component. The traction wheel is mounted on the rotating shaft through a bearing and can rotate freely around the shaft to reduce frictional resistance. The limiting groove block on the side of the rotating shaft fits into the double cable structure of the cable assembly to form a track-type constraint guidance mechanism. When the main body moves along the cable direction, the limiting groove block is embedded in the preset trajectory of the cable, forcing the traction wheel to maintain the predetermined direction of movement and avoiding the risk of derailment caused by load imbalance, wind disturbance or slight deformation of the cable.

[0017] 2. Compared with the existing technology, this small cable crane system for lifting in difficult mountain valleys uses fixed components as the connection hub between the support mechanism and the rock mass of the mountain valley. Its first fixed ring and second fixed block are directly anchored to the rock mass or stable structure to form a rigid connection, while the side chains flexibly interconnect the fixed components and the support components. This not only provides the support body with the ability to share loads in the horizontal and vertical directions, but also offsets some of the stress concentration caused by terrain subsidence or vibration through flexible constraints.

[0024] Example 1

[0025] As attached Figures 1 to 4 The system shown is a small cable crane system for lifting in difficult mountain valleys, including a main body 1, a support mechanism 2, and a traction component 3. The traction component 3 is located below the support mechanism 2, and the main body 1 is mounted on the side of the support mechanism 2. The main body 1 includes a sliding component 4, a connecting component 5, and a cable component 6. The cable component 6 is mounted on the outer diameter surface of the sliding component 4, and the connecting component 5 is mounted below the sliding component 4.

The support component 8 is mounted on the side of the fixing component 7, and the reversing component 9 is mounted on the side of the fixing component 7 away from the support component 8.

[0026] In this system, the support mechanism 2 serves as the overall support foundation, with its fixing component 7 anchored to a stable structure in the mountain valley, providing a stable anchor point for the system. The support component 8 forms a support force chain from below, ensuring the overall stability of the support mechanism 2. The reversing component 9 forms a direction conversion node on the support mechanism 2. The main body 1 is the core part that realizes the hoisting function. The cable component 6 is connected to the support mechanism 2, forming a double-cable supported load-bearing track. The sliding component 4 slides along the cable component 6, providing guidance for the movement of the main body 1. The connecting component 5 is connected below the sliding component 4 to suspend the hoisting load and transfer the load weight to the sliding component 4 and the cable component 6. The traction component 3 serves as a power source, changing the direction of the force by cooperating with the reversing component 9, driving the main body 1 to move horizontally along the direction of the cable component 6, thereby realizing the horizontal transportation of the hoisting load in the mountain valley. All components work together to adapt to the complex environment of the rugged mountain valley and complete small hoisting operations.

In the support assembly 8, the support foot 25 contacts the ground or rock mass, and the load is transferred to the support body 27 through the connecting column 26, forming a bottom-up support force chain to ensure that the support body 27 remains horizontal.

[0035] In a preferred embodiment, the reversing assembly 9 includes a fixed pulley 28, a second fixed shaft 29, and a third fixed block 30. The second fixed shaft 29 is mounted on the inner diameter surface of the fixed pulley 28. The fixed pulley 28 and the second fixed shaft 29 are connected by bearings.

[0036] In this embodiment, the winch 10 is a commercially available device known to those skilled in the art. It can be customized or a specific model can be selected according to actual needs. Here, we are simply using it without making any structural or functional improvements, and we will not elaborate further on that.

[0037] The working process of this utility model is as follows: First, when the operator uses the system, he / she needs to check whether the support mechanism 2 is stable, confirm that the first fixing ring 22, the second fixing block 23 and the chain 24 of the fixing component 7 are reliably anchored to the rock mass, the support foot 25 of the support component 8 is firmly grounded, the connecting column 26 and the support body 27 are not loose, and the fixed pulley 28 of the reversing component 9 is firmly installed through the second fixing shaft 29 and the third fixing block 30 and rotates smoothly. Then check the main body mechanism 1, the first fixing cable 19 and the second fixing cable 20 of the cable assembly 6 are tightly connected to the support mechanism 2 through the limiting ring 21 and the tension is appropriate, the traction wheel 13 of the sliding component 4 is mounted on the cable through the rotating shaft 14, the limiting groove block 15 fits the cable to ensure that it does not derail, the connecting plate 16 of the connecting component 5 is firmly fixed to the bottom of the sliding component 4, and the hinge structure formed by the first fixing block 17 and the first fixing shaft 18 can stably suspend the load.

[0038] Once ready, the hoisting load is hung on the connecting assembly 5 via the first fixed shaft 18. The winch 10 of the traction assembly 3 is operated, causing the traction cable 11 to change direction via the fixed pulley 28 of the reversing assembly 9. This causes the main body mechanism 1 to move via the traction block 12. At this time, the traction wheel 13 of the sliding assembly 4 rolls around the rotating shaft 14 along the first fixed cable 19 and the second fixed cable 20. The limiting groove block 15 maintains directional stability. The load weight is transmitted to the sliding assembly 4 and the cable assembly 6 via the first fixed shaft 18, the first fixed block 17, and the connecting plate 16. The chain 24 of the fixed assembly 7 assists the support assembly 8 in sharing the load. The support feet 25 and the connecting column 26 of the support assembly 8 ensure the stability of the support body 27. The above describes the working principle of this small hoisting cable crane system for difficult mountain valleys.
